THE COTTAGES OF COLLEGE STATION SUBDIVISION
MARCH 2009
The Cottages of College Station Subdivision is located on the south side of FM2818 at the future
extension of Holleman Drive . The project will consist of commercial tracts near FM2818, with
multifamily developments west of the Holleman Drive extension. This report presents the water li ne
analysis for the Final Plat of Lot 1, Block 3 and Lot 2, Block 1, Manor Avenue and a Portion of
Cottage Lane, Holleman and Market Street Rights of Way, the Cottages of College Station
Subdivi sion .
The updated City of Co ll ege Stat ion water system ln foWate r model, compiled by Nick Dons at
Freese & Nichols in January 2008, was checked against a flow test performed on hydrants within
the 2818 Place Apartment Complex . Results were reasonably close to those found by flow tests
under both static and residual conditions . Please see Exhibit 1 for the hydrant flow test report and
Exhibit 2 for a map show in g the tested hydrants .
Flow Test and MikeNET Comparison
Method Static Residual Demand
Flow Test 108.0 psi 104.0 psi 1405 gpm
MikeNET 94 .6 psi 90. 7 ps i 1405 gpm
Domestic flows were based on the Sep t ember 2008 Conce pt Plan for the Cottages of College
Station (Ex hibit 3 ) using maximum densities as sho wn and 2 .7 people estimated per dwelling unit.
Open and green spaces were assumed to generate no domestic demands . A preliminary site layout
for the Cottages development (Lot 2, Block 1) was used to determine bedroom counts for this tract
and is provided in Exhibit 4 . Flows for the Cottages were based on a demand of 100 gpd/bed plus
an additiona l use for the clubhouse. Analyses we re performed with Phase 2 of the 2818 Place
development complete . Domestic demands for 28 18 Place were calculated as 100 gpd/person
based on bed counts as provided in the site plans for each phase. Flows for commercial uses were
based on Normal Flow Method 2 as described in the 2008 BCS Unified Design Guidelines .
Fire demands were est imat ed on typical demands for similar sized developments. Commercial land
uses were assumed to have a fire flow demand of 2500 gpm . This figure allows for a wide range of
building sizes, and larger sites if a 50% sprinkler reduction is util ized . Multifamily residential was
assumed to have a fire flow demand of 2000 gpm. This would allow for two story non-
sprinkler eq u ipped un its or spri nkler equ i pped three story units at the maximum densities
as shown in the Cottages of College Station Concept Plan (Exhibit 3). A fire flow of 1500
gpm for the Cottages was based on preliminary architectural designs, with the largest area

demands and fire demands for each area are shown in the tab le below .

The MikeNET model was updated with the waterlines proposed with the plat as well as future
waterlines which will ser ve ultimate development as described in the concept plan . The proposed
and future waterline alignments are shown in Exhibit 7. MikeNET line and node identifiers are
provided in Exhibit 8. Fires were placed on various sections of the system under different conditions
of development:
1. Plat waterlines (proposed) and cottages development constructed only (Exhibit 9)
2 . All waterlines (proposed and future) and all development constructed, with a fire at Area A
(Ex hibit 1 O)
3. All waterl ines (pr oposed and future) and all development constructed, with a fire at Area H
(Exhib it 11)
4. All waterl ines (proposed and future) and all development constructed, with a fire at Area F
(Ex hibit 12)
It was found that the proposed waterlines under proposed (plat) and future conditions will
sufficiently serve the water needs of the Cottages of College Station Subdivision, keeping
pres sures in the proposed waterlines above 30 psi, and velocities at or below 12 fps .

Fire Service Standards
limited to banquet halls, night clubs, restaurants, taverns, and bars that exceed 5,000
square feet in area shall require an automatic sprinkler system. A Fire Department
Connection (FDC) is required for all buildings utilizing an automatic sprinkler system.
The FDC must be located within 150 feet of a fire hydrant.
Fire Flow Requirements
In general , the calculation area for fire flow requirements is based on the total gross
area of the structure, including any area under the horizontal projections of the roof of
the structure . Port ions of the building that are separated by fire walls w ithout
openings and constructed in accordance with the International Building Code, may be
considered as separate areas for the pu r poses of fire flow calculations. For type IA
and type IB construction, the calculat ion shall be based on the area of th e three
largest successive floors.

Re : Capstone Development Preliminary Trip Generation Report
Dear Ms. Morgan:
As per your request I have developed some trip generation and directional assignment
numbers for the proposed development. These numbers are based on the conceptual site plan you
provided, a copy of which is attached to this report as Figure 1. If the site plan changes considerably
the analysis will have to be redone based on the actual development proposal. It is assumed for this
preliminary report that the reader is familiar with the general location of the development.
The general area for this proposed development is bounded by FM 2818 on the north. The
areas to the south and southwest of the development area are generally residential in nature with
several subdivisions present and additional residential development proposals currently possible.
The primary existing roadway under consideration herein is Jones-Butler Rd. which connects to FM
2818 and continues north across that highway toward Texas A&M University. Dowling Rd. also
abuts the property and heads southwest into additional residential areas .
The task identified for this analysis was to determine the average daily traffic (ADT)
volumes which would be produced by the proposed development. These volumes are the added
volumes over and above the existing volumes which are present on Jones Butler Road and Dowling
Road at this time. The projected volumes represent the condition at build out, which will obviously
not be reached immediately. The volumes developed are then be compared to the capacities
presented in the Bryan-College Station Unified Design Guide for Streets for the various roadway
classes identified to determine capacity will be consumed by this development. Please recognize
that the actual capacity of a roadway, such as the ones under consideration herein, is largely
controlled by the intersection capacity at adjacent intersections. The intersection capacity is based
on the geometrics and type of control at the intersection and the conflicting volumes. Intersection
capacity is beyond the scope of this initial assessment.
This assessment was produced in essentially three parts. The first is the trip generation
which is shown for ADT on Figure 2 and for Peak Morning Hour as Figure 3. The data is broken
down into small areas as shown on Figure 1 and is presented in tabular form. Both tables are based
on a determination of the number of actual beds (persons) in each sub-area identified, based on the
building type, and the trip generation rates taken from the Institute for Transportation Engineers
(ITE) Trip Generation data (7 1h ed .). This resource compiles data for numerous trip generation
Civil Engineering Transportation Engineering Accident Reconstruction
Capstone Prehn_ ,ry Trip Generation Report
Page 2
studies from around the United States and includes a number of potential land uses, each of which
is numbered for reference. For this study the residential land use fo,r Apartments (220) and Low
Rise Apartments (270) were considered. The data is given for ADT and for the morning peak
period, which is estimated to be the largest peak hour for this development. The commercial
development is non-specific in type at this point and was analyzed as generic Shopping Center
(820). Average values are used for each type.
Commercial development typically generates some new traffic but also captures some of the traffic
that is already on the roadway, or in this case, generated by this proposed additional residential
development. The interest in this study is for the new additional trip generation so the raw trip
generation numbers are reduced by a "Passerby Percentage". These reductions are shown in the trip
generation tables only for the commercial traffic since the residential traffic will generate totally
new volumes. The passerby percentage used in this analysis is 35% for the ADT and 45% for the
peak hour. These values should be reasonably accurate since the commercial development is not on
a major thoroughfare. The peak hour passerby figure is higher since the morning peak is the larger
and captured traffic is higher at that time since there are less general shoppers out then. Diverted
link trips are not analyzed in th is report as they are beyond the scope of this preliminary analysis .
The trip generation is summarized on Figures 2 and 3. The total additional ADT expected from this
development is about 8400 Vehicles per Day (VPD). The comparable maximum hourly volume
generated is about 644 Vehicles per Day (VPD).
The second task was to assign the newly generated traffic volumes to the driveways and roadways
in question. These driveways have been labeled on the site plan shown in Figure 1. The
development area was broken down in to contributory sub areas, much like a drainage analysis is
done. In this case the assignment of traffic from a particular area is somewhat subjective based on
the judgement of the author and experience in the field. Generally traffic will seek the path ofleast
resistance when entering and leaving a development area. In this case, the primary access location
will be from FM 2818 via the traffic signal at Jones Butler Rd. Traffic entering the development
will practically take the shortest route allowable and has been assigned that way. Traffic leaving
the development has to compete with existing traffic on the roadways and with other traffic leaving
the development. This typically produces a slightly more varied distribution where the shortest path
in distance is not necessarily the shortest path in time. For example, traffic exiting area #5 would
exclusively use Dowling Rd., whereas traffic from area #15 must choose between driveways 2, 3
and Dowling Rd., depending on the traffic conditions expected. The Directional Assignment data
for ADT is presented in Figure 4. The traffic assignments assume that all outbound traffic from the
residential area of th is development uses Jones-Butler to the north . This assumption is based on the
type of development in this proposal and the type of existing development to the south .
These data show total additional trips on Jones Butler of 8398 VPD and for Dowling Rd. of
1362 VPD. These compare to existing (2006) volumes of3818 VPD on Jones Butler and 3604 VPD
on Dowling Rd. The existing volumes were provided by Troy Rother, of the City of College Station
staff, based on a 2006 traffic count in the area in question.
The third area of work includes a comparison of projected volumes to the prescribed
volumes for the given roadway classifications included in the Street Design Guide mentioned above
and included attached to this report. The range of volume s for a Major Collector is from 5000-1000
VPD. The range of volumes for a Minor Arterial is from 5,000 to 30 ,000 VPD . Generally roadway
Capstone Prelin. .ry Trip Generation Report
Page 3
classification is based on roadway function which is affected by trip type and trip length. A
development such as the proposed one generates substantial traffic, but requires only a major
collector type street to allow access to the roadway network. For this development that trip is short,
essentially the distance to FM 2818. The traffic volume generated by this development contributing
to Jones-Butler falls primarily in the range for a Major Collector street which geometrically and
functionally would meet the needs of this development. The approaches to a signalized intersection
would be satisfactory as well with two approach lanes for the volumes presented here for this
development. While Jones-Butler may eventually function as a minor arterial because of trip length,
it will not do so based on this development.
The specified capacity of a minor collector street is 1000 to 5000 VPD. The trip generation
by this development which will contribute to Dowling Rd. is comfortably within this range.
Functionally, the traffic generated by this development using Dowling Rd. only needs a minor
collector for that service.
This completes the presentation of the preliminary analysis of this proposed development.
The conclusions presented below summarize the material contained in the body of the report.
Conclusions
1. The trip generation for this development proposal should be approximately 8400 VPD with
a morning peak of about 644 VPH.
2. Of these trips about 1263 will use Dowling Road and all 8400 will use Jones-Butler Road.
3. This development justifies the use of major collector geometrics on Jones-Butler and minor
collector geometrics on Dowling Road.
If you have questions regarding this information please direct them to me at your
convemence.
Sincerely,
Jeffrey T. Milburn, P .E.

The above construction estimate is based on the engineer's preliminary opinion of probable construction costs . This estimate constitutes our
best judgment at this time. Please note that the engineer does not have any control over contractor or supplier workloads and the degree to
which inflation may affect project costs between now and the bid date . During construction, additional features may become apparent as the
work progresses, which will result in an increase in cost.

(TXR 150000) is for construction activities disturbing at least 1 but less than 5 acres or is part of
a common plan of development disturbing at least 1 but less than 5 acres .
You will need to follow these step s to discharge storm water from your construction site to the
City of College Station's Munici pa l Separate Storm Water Sewer System (MS4):
1. Read the general permit (TXR 150000) to make sure it applies to your situation.
2 . Adhere to the requiremen ts of the general permit (TXR150000).
3 . Prepare and implem ent a Storm Water Pollution Prevention Plan in accordance with
Part Ill of the general pe r mit (TXR150000).
4 . Sign and post a con structi on site notice .
5 . At least 2 days befo re beg inning construction , provide a copy of the site notice to the
operator of any Mun icip a l Separate Storm Water Sewer System (MS4) into which storm
water will be discharged .
A MS4s include streets , channe ls, gutters , ditches or anything else that is publicly owned,
designed or used to collect or tra nsport storm water.
As long as you meet the co nditio ns of this general permit , you are authorized to discharge
storm water.
No notice of intent (NOi), notice of termination (NOT), or fee is required under this option-as
long as the requirements of this general permit are followed .

Holleman Drive Extension Meeting #9 -July 22, 2009 -2pm
Meeting Minutes
Attendees : Mark Smith , CS Public Works Director
Jeff Robertson , McClu r e & Brown e
Veronica Morgan, Mitchell & Morgan
Karl Nelson , TxDOT
Ryan Jackson , TxDOT
Troy Rother, CS Public Works
Meeting began with a discussion of the following it ems :
l. TxDOT/Wellborn Road Overpass Status -Mark asked how long TxDOT thought the right in/
right out status on Jones-Butler will remain . Ryan and Karl ind icated that they were working
with the contractor to keep that status as long as possible. The contractor had planned to use
the Jones -Butler area as a staging area but has been willing to work to keep it open . Mark
stated that his projection for Holleman extension is a bid letting i n October and completion in
March 2010 . Ryan stated the the contract or will have to rebuild Jones-Butler at the intersection
but that probably does not need to happen until after March .
2. TxDOT AFA-All parties discussed the fact t hat a driveway permit will no longer suffice for the
connection to FM2818 and that will need t o be changed to an AFA. Veronica agreed to call Bob

RE: Capstone -Revised Holleman Plans
Dear Josh:
June 3 , 2009
Attached are the revised plans for the first phase of Holleman Drive . You will note that Manor,
Market and Cottage are still shown but are shaded differently to denote that ONLY Holleman will
be constructed with this contract. We have removed all sheets from this plan set that involved
only Manor, Market and Cottage since they will be constructed with a future contract. The
splitting of this plan set is in an effort to move the Holleman construction forward wh ile the
details of the internal street system (i.e . Manor, Market and Cottage) are being resolved by the
developer. As discussed , we have changed the following details on these three internal streets
to meet the requests of the city , namely :
• Remove the "bump outs " at the intersections which were inserted to create protected
parallel parking stalls and increased pedestrian queuing area at the intersections ,
• Narrow the cross sections on these three streets from 4 7 feet to 44 feet wide to allow for
increased width for parallel parking and bus turning radius but not the extra width to
allow for the "bump outs ", and
• Remove all parallel parking striping .
We are only noting these changes because they do affect the apron sections of Manor and
Market that will be constructed with this contract. You will see the majority of these changes
with the revised set of plans for Manor, Market and Cottage Streets . As for changes to
Holleman Drive we did modify the right turn from FM2818 to Holleman to tighten the geometry
and kept the right turn from Holleman to FM2818 to allow for improved operation of the
intersection . We hope we have addressed all of the concerns expressed during our last
discussion on this project. Please let us know if we have missed anything or there are further
c mments on th is plan set. Thank you for all your help in moving this project forward .

PCN for Holleman
0716-delineation _map-Layout1 .PDF
You had one comment on our Holleman plans that sa id someth ing like con fi rm
that the re is no need for a USACE permit on this project. My response was we
did not need one and what type of confirmation are you requesting. Since
that time I called Loretta Mokry and she said to tell you guys that
Holleman Part 1 is covered under the Nationwide permit for Linear Roadway
Cross ings (NWP 14 ) And the threshold establ ished in that NWP is ONLY if your
disturbance of the regulatory stream (below mean high water mark) is over .1
acres do you have to submit a PCN (Preconstruction Notifica ti on). Our
disturbance as seen on the attached graphic at th is location is less than
the .1 acres . Does this help?

We appreciate you and your client's willingness to accelerate the design and construction of Holleman Drive extension to Jones
Bulter. We believe this effort and likely agreement is in the best interests of both the residents of this area, the developer, and
general mobility . Below are points of guidance:
-The street cross-section of lane widths (from B/C) of 12 .5, 12, 12, and 12.5 ft with a 5 ft median and bike path are acceptable
-noting is still has an outer curb of the standard 54 ft for a Major Collector. The "bulging" of the pavement and possible
increased ROW for left turn lanes with a minimum of 10 is acceptable as well.
-Staff will recommend participation for the costs of the roadway on the city property. The "bulging" left turn lane (similar to
Minor Arterial Section) is an acceptable addition if at the developer's cost -however the city participation for these additions will
need to be reviewed prior to staff indicating support for recommendation of city participation. Similarly the cost of the reduction
of the lanes to 3 through the city property needs to be reviewed prior to support, however there is less interest unless it could
be easily have the 4th lane added.
-The city's participation not exceed 30% due to the timing of the additional bidding requirements. A city participation
agreement cannot be reached until costs and percentages are initially agreed upon. Construction Plans will not be required for
the agreement, but an engineer's estimate and schematic with description will. The standard city participation agreement and
flowsheet is attached .
-12 ft bike path, 5 ft off the curb
-the sidewalk is preferred to be 3 ft off curb and 6 ft wide
-Public Access Easements are adequate where sidewalk/bike path extends beyond the ROW including a allotment for
maintenance and tying back to grade if necessary
-4 ft between the sidewalk/pathway and parking is adequate for screening planting. However note Jason's comment that this
POD doesn't allow parking infront of the buildings for all of the lots but one
I have copied others that may have additional comments.
Thanks.

Alan,

In follow ing up on our conversation regarding the bike path along Holleman Drive extension, I wanted to detail how we got to
where we are and what implication it may have on private property. I'll start with background and work up from there:
1) The Bikeway and Pedestrian Plan shows an off-street bike path along Jones Butler Road. Jones Butler has been realigned to
the signal at Holleman.
2) From the Sub Regs, the standard width of a bike path is 10 feet. Since it parallels a road and would duplicate the standard
sidewalk, we felt the two could be combined but it would need to be a 12-foot width the Sub Regs describes.
3) Work ing with the assumption that the ROW is 80 feet and the pavement is 54 feet back to back. This leaves 13 feet of ROW
outside the curb on each side . If a wider cross section is used, then some of the following statements would need to be
adjusted to reflect it.
4) The Sub Regs state bike paths adjacent to roadways are to be a minimum of 5 feet from the road .
5) With the bike path at least 5 feet off of the curb and 12 foot in width, the outside edge of it is at least 17 feet from the curb.
There is only 13 feet of ROW outside of the curb so a public access easement is necessary.
6) We've requ ired a minimum 6-foot public access easement outside the ROW edge that the bike path is on. This would allow 2
feet of wiggle room for the path and help account for any grading off of it.
As for private property implications, my understanding is this:
1) Provide a minimum 6-foot wide public access easement along the edge of the ROW.
2) Non-residential development meeting NRA has a minimum parking set back of 10 feet from the ROW . No multi-family (which
requires only a 6 foot parking setback) is directly adjacent to the Holleman Drive extension.
3) Note #5 on the approved POD Concept Plan precludes parking directly along Holleman. It states "Parking for the commercial
areas (Fl, Bl-B4) shall be located in a manner so as to be located on the interior of the commercial area or at the drive
entrances between buildings but not located parallel to Holleman and FM 2818 and in front of the commercial build in gs along
these roadways." In short, parking can be located directly along these ROWs, only off of entrance driveways going past
buildings which would need to meet a 25 foot throat depth too. This requirement does not apply to commercial area "F2"
however which is located at the southwest corner of Harvey Mitchell and Holleman Dr ive.
I know this has been a long explanation but I hope it provides insight to about all the factors involved . Let me know if you have
any questions.
Thanks,
Jason

Gentlemen,
Thanks so much for your time today .. It was extremely helpful and very very
much appreciated .... .! realize it was a long meeting but I think we actually
got through a lot of discussions/decisions that were very important. I
promise the next meeting will be more focused and we can get out quicker.
To synopsize our discussion/decisions today:
1. We will design a 12' hike/bike path along the east side of Holleman.
The city will be designing a project in the future to carry those bicyclists
along the existing Holleman Drive to the north. This may be on street bike
lanes with parking removed or a bike path, unknown at this point. We will
get the two way bike path across FM2818 in a single cross walk and when the
bike lanes/path are designed in the future that design will figure out how
to split the cyclists from a two way path to single lanes, if warranted .
2. Because of the concerns with left turning traffic blocking the
center thru lane and with the realization that curb cuts will be requested
and would meet driveway spacing along the retail side of Holleman and the
hard corner of Holleman/FM2818 it was decided to go to the following roadway
section. The standard for 4 lanes is 15'/12'/12'/15' lane configuration.
We will do 12.5'/12'/5.5'center median/12'/12.5' (b/c-b/c). Th is does not
meet any of the design guidelines for a major collector but is the best
configuration to avoid losing the capacity of the inside lane . We will keep
a min 10 ' left turn bay . The center median will allow for better control of
left turns and allow for ped/bike traffic to cross Holleman to/from the
retail without running across 4 lanes of traffic (it gives them a refuge
point in the center).
3. Where possible we will provide any location for trees in the median.
4. Within the area from Manor Avenue to just past Dowling Road we will
"bulge" out the pavement section to allow for left turn bays from Holleman
on to Market and Dowling. We will not allow for left turning traffic from
Manor to Holleman or vice versa. Because of the median continuing along
Holleman thru the Manor intersection, Manor and Market will really function
as a one-way loop although it will be two way traffic . Manor will become rt
in/ rt out.
5. It was agreed that Market should be revisited (not with this
project) so that it doesn 't become a cut-thru and replace Dowling as the
major collector in the area .
6. We looked at our intersection design already of Holleman/2818 and
everyone liked it with the addition of the median to be added. Alan wanted
us to talk to Eddie Hare re: TAS requirements for the he ramp crossing of
2818 .
7. Alan/Joe are going to find out ASAP if truly we w ill not have to do
any environmental studies for txdot so long as we don't apply for a driveway
permit prior to some magical date in March.
8. Alan is going to find out about placing the hike/bike path at back
of curb .
9. M&M is going to see if the "bulging" as described above will require
more row or if it will fit and we can dedicate an easement adjacent to the
row for maintenance purposes.
10. Alan said the "bulging" would be something we would apply for
oversize participation for.
11. We discussed two items with regard to how to work with the
construction phasing of the intersection of Jones-Butler and Dowling. We
would like to shut it down completely during the time the contractor has to
build just the intersection and reroute traffic to other locations. The
ideal would be for the city to place a culvert /base on part and seal coat
the street between the pump station and the school in Quail Run . This could
be the outlet for traffic during what we believe will be 3 weeks max to
construct the intersection. The east side of Dowling is a little more
tricky although volumes much less . With that area we would like to see if
txdot would let the contractor pave a temporary drive within the 2818 row
between Dowling and the driveway to the mobile home park . Txdot is having
to keep the mobile home park driveway operational during their construction
so this minimal Dowling Road traffic could use that same connection to 2818
for 3 weeks. It would then be removed. This will make the design and
construction go much faster and cheaper since we wont have to accommodate
that traffic within the intersection .
12. M&M will chk with bob cowell on dev agreement status and when that
will get to city council b/c we cant cut Mcclure/browne loose until council
agrees . Mcclure/browne is stuck and cant give m&m a proposal until txdot
answers #11 above. (it means a lot more design work if we cant do #11)
13 . City needs some graphics to go with dev agreement and prelim eng
estimates . We will use prelim plat figures and prelim estimates for dev
agreement.
14 . Streetscape and the council's desire to have trees along this
roadway was discussed but no conclusions drawn.
Ok I th ink I got it all .. If I missed anything please let me know ....

Sorry I didn't get back w you sooner. I spoke w Harvey re this and checked statute. Progress paymts along the lines you
reference are fine . modify the form participation agreement and Legal will review .
Also , since they'll be constructing on our property, we need to give them permission to be on our property to do the roadwork
and related work (utilities? drainage?), and they need to assume liabiity and indemnify us and name us as an insured for
anything that occurs on our property relating to the road construction .
Remember that sect. 212 .074 LGC requires this agreement be adopted by ordinance , absent having a provision in our UDO that
adequately addresses this issue.

Reminder as we discussed today, David Neeley has requested we consider allowing monthly payments on this pending city
participation agreement. Veronica has made this request for her client -Mark and I have a meeting with them at 3pm this
Thurday 4/2/09 .
I think we can cut and paste payment language from the standard construction contract to the city participation contract to cover
partial payments , retainage, material on hand , etc . This is intended to be a special agreement and not a standard agreement.
This oversizing (extension) is for a particular reach of Holleman proposed through city property -and I would suggest the
payments be for work specifically done on the city's reach as verified by myself and my inspector. Again I'm told this project is
critical to Council and Management -and is time sensitive due to TxDot project on 2818 by Wellborn Road . The City's share
looks to be -$1 M (this amount is currently available in OP street funds) and should be just under 30% of the total project, not
requiring public bidding . The Developer/Contractor would provide payment and performance bonds for -$3 .5M. Construction is
anticipated in next month or two , through the end of the year.
Thanks for your help . Let me know if you have questions .

Page 1of 3
Joe -Veronica is requesting $45k City participation for the free right turns at the intersection with 2818. She believes TxDot will
require the decell lane but not the free rights. Can you confirm whether the TIA speaks to the free rights?
Troy -Similarly, do you think the free rights are warranted and we should participate? Also, she has $16.Sk + $7k Dev /$5.Sk +
$15k City costs for signage and stripping included. We do not require the developer to stripe at all. I suppose we could OP if
we want them to stripe it.
Mark -This request is approximately $1M on a $3M. However, she did not include costs for the "purple" Market and Doweling,
nor extension of Cottage Lane, nor onsite public utilities -which she anticipates will bring it well under 30%. We had previously
discussed reducing the City portion's section if we simply don't have the money and operationally may not have a significant
impact? Do we want trees in City's portion?
Timeline: Construction plans are submitted for the "green" portion which could begin in coming weeks. Next they need the city
participation agmt (2 mos) approved so they can subcontract the design (2 mos) to McClure and Browne on the "blue" and
"yellow" extension of Holleman. That would leave 6 or 7 months to bid and construct the remainder of Holleman by the end of
the Calendar year.

Guys,
Here is the prelim estimate for Holleman. Notice that there are two sheets.
The first is Holleman from FM2818 to the end of the current Capstone
project. The only city cost participation that I am seeing right now on that
end is participation in the larger intersection (free rights) at the signal
that we would be applying for. I do not have costs in here yet for the
decel and accel lanes associated with those free rights.(still talking to
t:xdot and waiting for addt'I survey). The other cost I don't have in here
yet is for the upgrade in striping from paint to thermo. (still trying to
round up an estimate for that)
The second page is the remainder of Holleman from the end of the current
project to Jones-Butler. There are some costs on the city portion of this
file ://C:\Documents and Settings\agibbs.CSTX\Local Settings\Temp\XPgrpwise\49BA4ED7City of Colle ... 3/13 /2009
project that I pulled out of the air ( ie fiber reroute costs and
intersection cost) . It is too early in the design to know those costs
exactly. These may come down. The city IT dept is curious who is paying for
the fiber reroute work that would need to be done Uust fyi). The roadway
costs alone are coming in pretty close to what we estimated in the meeting
with the asst. city mgr. ($750,000 for the street). But the total est is
much higher .... There are things the city might want to do to get costs down.
(i.e. not construct the waterline at this time or the sidewalk or hike/bike
path). I don't know what you budget allotment is for this work but I can
help give you cost cutting ideas. This estimate carries the median cross
section and s/w and hike/bike through the existing dowling intersection to
the terminus with j-b. It does not include the quail run work to divert
traffic -we can add that if we need too. I think the estimate is high and
will come down as we get into the details of the design and know more.
Hope this helps and let me know if you need any other information. The
graphic is attached so that you can see the limits associated with these
costs.

schedule, unless objected to by the City, shall be used as a basis for reviewing the
Contractor's Applications for Payment. On or before the ___ day of each month, the
Contractor shall submit to City's Representative, for approval or modification, a statement
showing as completely as practicable the total value of the actual work performed by the

with this Agreement, the City shall pay the remainder of the balance due under this
Agreement, less any sums withheld under other terms of this Agreement and less the

16.05 . If the actual amount of work to be done and the materials to be furnished differ
from estimates and where the basis for payment is the unit price method, then payment shall
be for the actual amount of accepted work done and materials furnished on the Project.
16.06. Reduction in the scope or quantity of work on unit price items shall merely reduce
the number of units. In the event that materials have been delivered prior to notice of such
reduction, the City will have the option either to pay freight & transportation costs and any
re-stocking charges actually incurred by the Contractor or to purchase the materials. The
Contractor shall never be entitled to anticipated or lost profits on the deleted or reduced
portion of a job, whether bid on a unit price or lump sum basis.

delivered at the site and all required taxes, less applicable trade discounts;

Paragraph 16 .9(b).
16.10. Suspension of Payments. The City, at any time, may suspend monthly progress
payments on the work if it determines that the projected liquidated damages may exceed
retainage. The City, at any time, may suspend monthly progress payments if it believes that
the Contractor will not complete the work due to actual default or that the Contractor has
represented or done some act that indicates that it will not complete the work in accordance
with this Agreement or within the time period submitted in its bid. Provided, however, City
is in no way obligated to Contractor's surety to withhold payment pursuant to the provisions
of this Paragraph.
16.11. Withhold Funds. Regardless of any bond, the City may, on account of
subsequently discovered evidence and in addition to the retainage withheld under Paragraph

Ms. Loretta Mokry

1320 South University Drive, Suite 300
Fort Worth, Texas 76107-5737
Dear Ms. Mokry:
Thank you for your letter of May 13, 2009, and follow-up submittal dated October 2, 2009 ,
concerning a proposal by Capstone-CS, LLC to construct the proposed Capstone Cottages
Residential Development and Holleman Drive Phase I Extension located on a 105-acre tract of
land at the intersection of Harvey Mitchell Parkway and Holleman Drive in the City of College
Station, Brazos County, Texas. This project has been assigned Project Number SWF-2009-
00206. Please include this number in all future correspondence concerning this project. Failure
to reference the project number may result in a delay.
We have reviewed this project in accordance with Section 404 of the Clean Water Act and
Section 10 of the Rivers and Harbors Act of 1899. Under Section 404, the U.S. Army Corps of
Engineers (USA CE) regulates the discharge of dredged and fill material into waters of the United
States, including wetlands. Our responsibility under Section 10 is to regulate any work in, or
affecting, navigable waters of the United States. Based on your description of the proposed
work, and other information available to us, we have determined that this project will not involve
activities subject to the requirements of Section 10. However, this project will involve activities
subject to the requirements of Section 404. Therefore, it will require Department of the Army
authorization.
We have reviewed this project under the preconstruction notification (PCN) procedures of
Nationwide Permit (NWP) General Condition 27 (Federal Register, Vol. 72 , No. 47 , Monday,
March 12, 2007 and corrections in Federal Register Vol. 72, No. 99, Tuesday, May 8, 2007). We
have determined that this project is authorized by NWP 29 for Residential Developments and NWP
14 for Linear Transportation Projects. To use these permits, the person responsible for the project
1,
-2-
must ensure that the work is in compliance with the specifications and conditions listed on the
enclosures and the special conditions Jisted below. The special conditions for these permits are as
follows:
1. The permittee shall implement and abide by the mitigation plan titled 11 Proposed Mitigation Plan
for Capstone Cottages Residential Development, College Station, Brazos County, Texas, USA CE
Project No.: 2009-00206" prepared by Loretta Mokry, Alan Plummer Associates, Inc., dated
October 2, 2009. The permittee shall implement the mitigation plan concurrently with the
construction of the project. Completion of all elements of this mitigation plan is a requirement of
this permit.
2. The permittee shall debit 7.9 credits from the Steele Creek Mitigation Bank in compliance with
the provisions of the HMitigation Banking Instrument, Steele Creek Mitigation Bank, Robertson
County, Texas," dated May 2004. This debit shall compensate off-site for unavoidable adverse
project impacts that would not be compensated for by on-site mitigation. The permittee shall
complete the mitigation bank transaction and provide documentation to the USACE that the
transaction has occurred by December 1, 2009.
We have determined that the proposed activities would comply with all of the terms and
conditions ofNWPs 29 and 14, and that adverse environmental effects of the proposed project
would be minimal both individually and cumulatively. Therefore, we are waiving the 300 linear
foot limit for loss of stream bed in this case. Failure to comply with these specification and
conditions invalidates the authorization and may result in a violation of the Clean Water Act.
Our verification for the construction of these activities under these nationwide permits is valid
until March l 8 1 2012, unless prior to that date the nationwide permits are suspended, revoked, or
modified such that the activities would no longer comply with the terms and conditions of the
nationwide permits regionally or nationally. The USACE will issue a public notice announcing the
changes when they occur. Fut1hermore, activities that have commenced, or are under contract to
commence, in reliance on a nationwide permit will remain authorized provided the activity is
completed within 12 months of the date of the nationwide permit's expiration, modification, or
revocation, unless discretionary authority has been exercised on a case-by-case basis to modify
suspend, or revoke the authorization in accordance with 33 CFR 330.4(e) and 33 CFR 330.S(c) or
(d). Continued confirmation that an activity complies with the specifications and conditions, and
any changes to the nationviide permits, is the responsibility of the permittee.
Our review of this project also addressed its effects on threatened and endangered species.
Based on the information provided, we have determined that this project will not affect any species
listed as threatened or endangered by the U.S. Fish and Wildlife Service within our permit area.
However, please note that you are responsible for meeting the requirements of general condition 17
on endangered species.

-3-
The permittee must sign and submit to us the enclosed certification that the work, including any
required mitigation, was completed in compliance with the nationwide permits. You should submit
your certification with 30 days of the completion of work.
This permit should not be considered as an approval of the design features of any activity
authorized or an implication that such construction is considered adequate for the purpose intended .
It does not authorize any damage to private property, invasion of private rights, or any infringement
of federal, state, or local laws or regulations.
The USA CE based this decision on a preliminary jurisdictional determination that there are
water of the United States on the project site. It is incumbent upon the applicant to remain
infom1ed of changes in the Depat1ment of the Army regulations.

Include but are not llmlted to roads , parking lots, garages, yards, utility lines, storm water management facilities,
septic fields, and recreation facllitres such as playgrounds , playing fields, and golf courses (provided the golf
course Is an integral part of the residential development).
The discharge must not cause the loss of greater than 1/2-acre of non -tidal waters of the United States ,
including the loss of no more than 300 linear feet of stream bed, unless for intermittent and ephemeral stream
beds this 300 linear foot limit is wa ived in writing by the district engineer. This NWP does not authorize discharges
.into non-tidal wetlands adjacent to tidal waters . ·
Subdivisions: For residential subdivisions, the aggregate total loss of waters of United States authorized by
this NWP cannot exceed 1 /2 acre. This includes any loss of waters of the United States associated with
development of individual subdivision lots.
Notification : The permlttee must submit a pre-construction notification to the district engineer prior to
commenc ing the activity. (See general condition 27 .) (Sections 10 and 404)
NATIONWIDE PERMIT GENERAL CONDITIONS
General Conditions: The following general conditions must be followed in order for any autho rization by a NWP to
be valid :
1. Navigation. (a) No activity may cause more than a minimal adverse effect on navigation.
(b) Any safety lights and signals prescribed by the U.S. Coast Guard, through regulations or otherwise , must
be installed and maintained at the permitlee's expense on authorized facilities In navigable waters of the United
States.
(c) The pe rmittee understands and agrees that , if future operations by the United States requ ire the removal,
relocation , or other alteration, of the structure or work herein authorized, or if, in the opinion of the Secretary of the
Army or his authorized representative , said structure or work shall cause unreasonable obstruction to the free
navigation of the navigable waters , the permittee will be required, upon due notice from the Corps of Engineers , to
remove, re locate, or alter the structural work or obstructions caused thereby, without expense to the United
States . No claim shall be made aga inst the United States on account of any such removal or alteration .
2. Aquatic Life Movements . No ac ti vity may substantially disrupt the necessary life cycle movements of those
species of aquatic life indigenous to the waterbody, including those species that normally migrate through the
area, unless the activity's primary pµrpose is to impound water. Culverts placed in streams must be Installed to
maintain low flow cond itions .
3. Spawning Areas . Activities in spawning areas during spawning seasons must be avoided to the maximum
extent practicable . Activities that result in the physical destruction (e.g ., through excavation, fill , or downstream
smothering by substantial turbidity) of an important spawning area are not authorized.
4. Migratory Bird Breeding Areas . .Activities in waters of the Un ited States that serve as breeding areas for
migratory birds must be avoided to the maximum extent pract.lcable.
5. Shellfish Beds. No activity may occur In areas of concentrated shellfish populations , unless the activity is
directly related to a shellfish harvesting activity authorized by NWPs 4 and 48 .
6. Suitable Material. No activity may use unsuitable material (e.g., trash, debris , car bodies, asphalt, etc .).
Material used for construction or discharged must be free from toxic pollutants In toxic amounts (see Section 307
of the Clean Water Act).
7. Water Supply Intakes. No activity may occur in the prox imity of a public water supply intake, except where the
activity is for the repair or Improvement of public water supply Intake structures or adjacent bank stabilizat ion .
8. Adverse Effects From Impoundments . If the activlty creates an impoundment of water, adverse effects to the
aquatic system due to accelerating the passage of water, and/or restricting its flow must be minimized to the
maximum extent practicable.
9. Management of Water Flows. To the maximum extent practicable, the pre-construction course, condition,
capacity, and location of open waters must be maintained for each activity, Including stream channelization and
storm water management activities, except as provided below. The activlty must be constructed to withstand
expected high flows. The activity must not restrict or impede the passage of normal or high flows, unless the
primary purpose of the activity is to impound water or manage high flows. The activity may alter the pre-
construction course, condition, capacity, and location of open waters if it benefits the aquatic environment {e.g .,
stream restoration or relocation activities).
10. Fiiis Within 100-Year Floodplains . The activity must comply with applicable FEMA-approved state or local
floodplain management requirements.
11. Equipment. Heavy equipment working in wetlands or mudflats must be placed on mats, or other measures
must be taken to minimize soil disturbance.
12. Soll Erosion and Sediment Controls. Appropriate soil erosion and sediment controls must be used and
maintained in effective operating condition during construction, and all exposed soil and other fills, as well as any
work below the ordinary high water mark or high tide Hne, must be permanently stabilized at the earliest
practlcable date. Permittees are encouraged to perform work within waters of the United States during periods of
low-flow or no-flow .
13. Removal of Temporary Fiiis. Temporary fills must be removed in their entirety and the affected areas
returned to pre-construction elevations. The affected areas must be revegetated, as appropriate.
14. Proper Maintenance. Any authorized structure or fill shall be properly maintained, including maintenance to
ensure public safety.
15. Wild and Scenic Rivers. No activity may occur In a component of the National Wild and Scenic River
System, or in a river officially designated by Congress as a "study river" for possible Inclusion In the system while
the river is in an official study status, unless the appropriate Federal agency with direct management responsibllity
for such river, has determined In writing that the proposed activity will not adversely affect the Wild and Scenic
River designation or study status. Information on Wild and Scenic Rivers may be obtained from the appropriate
Federal land management agency In the area (e.g ., National Park Service, U.S. Forest Service, Bureau of Land
Management, U.S. Fish and Wildlife Service).
16 . Tribal Rights. No activity or its operation may impair reserved tribal rights, including, but not limited to,
reserved water rights and treaty fishing and hunting rights.
17. Endangered Species. (a) No activity is authorized under any NWP which is likely to jeopardize the continued
existence of a threatened authorized under any NWP which "may affect" a listed or endangered species or a
species proposed for such designation, as identified under the Federal Endangered Species Act (ESA), or which
wlll destroy or adversely modify the critical habitat of such species . No activity is species or critical habitat, unless
Section 7 consultation addressing the effects of the proposed activity has been completed.
(b) Federal agencies should follow their own procedures for complying with the requirements of the ESA.
Federal permittees must provide the district engineer with the appropriate documentation to demonstrate
compliance with those requirements .
(c) Non-federal permittees shall notify the district engineer if any listed species or designated critical habitat
might be affected or Is In the vicinity of the project, or if the project is located In designated critical habitat, and
shall not begin work on the activity until notified by the district engineer that the requirements of the ESA have
been satisfied and that the activity ls authorized. For activities that might affect Federally-listed endangered or
threatened species or designated critical habitat, the pre-construction notification must include the name{s) of the
endangered or threatened species that may be affected by the proposed work or that utilize the designated critical
habitat that may be affected by the proposed work. The district engineer will determine whether the proposed
activity "may affect" or will have "no effect" to listed species and designated critical habitat and will notify the
non-Federal applicant of the Corps' determination within 45 days of receipt of a complete pre-construction
2
notification. In cases where the non-Federal applicant has identified listed species or critical habitat that might be
affected or is in the vicinity of the project, and has so notified the Corps, the applicant shall not begin work until
the Corps has provided notification the proposed activities will have "no effect " on listed species or critical
habitat, or unt il Section 7 consultation has been completed.
(d} As a result of formal or Informal consultation with the FWS or NMFS the district engineer may add
species-specific regional endangered species conditions to the NWPs. .
(e) Authorization of an activity by a NWP does not authorize the "take" of a threatened or endangered
species as defined under the ESA. In the absence of separate authorization (e.g., an ESA Section 1 O Permit, a
Biological Opinion with "incidental take" provisions, etc.) from the U.S. FWS or the NMFS, both lethal and non-
lethal "takes" of protected species are in violation of the ESA. Information on the location of threatened and
endangered species and their critical habitat can be obtained directly from the offices of the U.S. FWS and NMFS
or their worldwide Web pages at hltp://www.fws .gov/ and htlp://www .noaa .gov/fisheries.html respectively.
18. Historic Properties. (a) In cases where the district engineer determines that the activity may affect properties
listed, or eligible for Hstlng, in the National Register of Historic Places, the activity Is not authorized, until the
requirements of Section 106 of the National Historic Preservation Act (NHPA) have been satisfied .
(b) Federal permittees should follow their own procedures for complying with the requirements of Section 106
of the National Historic Preservation Act. Federal permittees must provide the district engineer with the
appropriate documentation to demonstrate compliance with those requirements .
(c) Non-federal permittees must submit a pre-construction notification to the district engineer if the authorized
activity may have the potential to cause effects to any historic properties listed, determined to be eligible for listing
on, or potentially eligible for listing .on the National Register of Historic Places, including previously unidentified
properties . For such activities, the pre-construction notification must state which historic properties may be
affected by the proposed work or Include a vicinity map Indicating the location of the historic properties or the
potential for the presence of historic properties. Assistance regarding information on the location of or potential for
the presence of historfc resources can be sought from the State Historic Preservation Officer or Tribal Historic
Preservation Officer, as appropriate, and the National Register of Historic Places (see 33 CFR 330.4(g)). The
district engineer shall make a reasonable and good faith effort to carry out appropriate identification efforts, which
may include background research, consultation, oral history interviews, sample field investigation, and field ·
survey. Based on the information submitted and these efforts, the district engineer shall determine whether the
proposed activity has the potential to cause an effect on the historic properties. Where the non-Federal applicant
has Identified historic properties which the activity may have the potential to cause effects and so notified the
Corps, the non-Federal applicant shall not begin the activity until notified by the district engineer either that the
activity has no potential to cause effects or that consultation under Section 106 of the NHPA has been completed .
(d} The district engineer will notify the prospective permittee within 45 days of receipt of a complete pre-
construction notification whether NHPA Section 106 consultation Is required. Section 106 consultation is not
required when the Corps determines that the activity does not have the potential to cause effects on historic
properties (see 36 CFR 800.3(a)). If NHPA section 106 consultation is required and will occur, the district
engineer will notify the non-Federal applicant that he or she cannot begin work untif Section 106 consultation Is
completed.
(e) Prospective permlttees should be aware that section 11 Ok of the NHPA (16 U.S.C. 470h-2(k)) prevents the
Corps from granting a permit or other assistance to an applicant who, with intent to avoid the requirements of
Section 106 of the NHPA, has intentionally significantly adversely affected a historic property to which the permit
would relate, or having .legal power to prevent it, allowed such significant adverse effect to occur, unless the
Corps, after consultation with the Advisory Council on Historic Preservation (ACHP}, determines that
circumstances justify granting such assistance despite the adverse effect created or permitted by the applicant. If
circumstances justify granting the assistance, the Corps is required to notify the ACHP and provide
documentation specifying the circumstances, explaining the degree of damage to the integrity of any historic
properties affected, and proposed mitigation . This documentation must include any views obtained from the
applicant, SHPO!THPO, appropriate Indian tribes If the undertaking occurs on or affects historic properties on
tribal lands or affects properties of interest to those tribes, and other parties known to have a legitimate Interest in
the Impacts to the permitted activity on historic properties.
19. Designated Critical Resource Waters. Critical resource waters include, NOAA-designated marine
sanctuaries, National Estuarine Research Reserves, state natural heritage sites, and outstand ing national
resource waters or other waters officially designated by a state as having particular environmental or ecological
significance and identified by the district engineer after notice and opportunity for public comment. The district
engineer may also designate additional critical resource waters after notice and opportunity for comment.
3
(a) Discharges of dredged or fill material into waters of the United States are not authorized by NWPs 7, 12 ,
14, 16, 17, 21, 29, 31, 35, 39 , 40, 42, 43, 44, 49, and 50 for any activity within, or directly affecting, crltical
resource waters, including wetlands adjacent to such waters.
(b) For NWPs 3, 8, 10, 13, 15, 18, 19 , 22, 23, 25 , 27, 28, 30, 33,
34, 36 , 37, and 38 , notification is required in accordance with general condition 27 , for any activity proposed in the
designated critical resource waters including wetlands adjacent to those waters. The district engineer may
authorize activities under these NWPs only after it ls determined that the impacts to the critical resource waters
will be no more than minimal. ·
20 . Mitigation . The district engineer will consider the foUowing factors when determining appropriate and
practicable mitigation necessary to ensure that adverse effects on the aquatic env ironment are minima l:
(a) The activity must be designed and constructed to avoid and minimize adverse effects , both temporary and
permanent , to waters of the United States to the maximum extent practicable at the project site (i.e ., on site).
(b) Mitigation in all its forms (avoiding, minimizing , rectifying, reducing, or compensating) will be required to
the extent necessary to ensure that the adverse effects to the aquatic environment are minimal.
(c) Compensatory mitigation at a min imum one-for-one ratio will be required for all wetland losses that exceed
1/1 O acre and requlre pre-construction notification, unless the distr ict engineer determines in writing that some
other form of mitigation would be more environmentally appropriate and provides a project-spec ific waive r of this
requirement. For wetland losses of 1/10 acre or less that require pre-construct ion notification, the distr ict engineer
may determine on a case-by -case basis that compensatory mitigation is required to ensure that the activ ity results
In minimal adverse effects on the aquatic environment. Si nce the likelihood of success is greater and the Impacts
to potentially valuable uplands are reduced, wetland restoration should be the first compensatory mitiga ti on opt ion
considered .
(d) For losses of streams or other open waters that require pre-construction notification , the district engineer
may require compensatory mitigation, such as stream restoration, to ensure that the activity results in minimal
adverse effects on the aquatic environment.
(e) Compensatory mitigation will not be used to increase the acreage losses allowed by the acreage limits of
the NWPs . For example, if an NWP has an acreage limit of 1/2 acre, it cannot be used to authorize any project
resulting in the loss of greater than 1/2 acre of waters of the United States, even if compensatory mitigation is
provided that replaces or restores some of the lost waters . However, compensatory mitigation can and should be
used, as necessary, to ensure that a project already meeting the estab li shed acreage iimlts also satisfies the
minimal impact requirement associated with the NWPs .
(f) Compensatory mitigation plans for projects in or near streams or other open waters wlll normally include a
requ irement for the establishment, maintenance , and legal protection (e .g., conservation easements) of riparian
areas next to open waters. In some cases , riparian areas may be the only compensatory mltlgatlon required .
Riparian areas should consist of native species. The width of the required riparian area will address documented
water quality or aquatic habitat loss concerns . Normally, the riparian area wlll be 25 to 50 feet wide on each side
of the stream, but the district engineer may requ ire slightly wider riparian areas to address documented water
quality or habitat Joss concerns. Where both wetlands and open waters exist on the project site, the distr ict
engineer will determine the appropriate compensatory mitigation (e.g ., riparian areas and/or wetlands
compensation) based on what is best for the aquatic environment on a watershed basis. In cases where riparian
areas are determined to be the most appropriate form of compensatory mitigation , the district engineer may waive
or reduce the requirement to provide wetland compensatory mitigation for wetland losses.
(g) Permittees may propose the use of mltlgation banks, in -lieu fee arrangements or separate activity-specific
compensatory mitigation . In all cases , the mlUgation provisions will specify the party responsible for accomplishing
and/or complying with the mitigation plan .
(h) Where certain functions and services of waters of the United States are permanently adversely affected,
such as the convers ion of a forested or scrub-shrub wetland to a herbaceous wetland ln a permanently
maintained utility line right-of-way , mitigation may be required to reduce the adverse effects of the project to the
minimal level.
21 . Water Quality. Where States and authorized Tr ibes, or EPA where applicable, have not previously cert ified
compliance of an NWP with CWA Section 401 , ind ividual 401 Water Quality Certification must be obtained or
waived (see 33 CFR 330.4(c)). The district engineer or State or Tribe may require additional water quality
management measures to ensure that the authorized activ ity does not result in more than minimal degradation of
water quality.
22. Coastal Zone Management. Jn coastal states where an NWP has not previously received a state coastal
zone management consistency concurrence, an individual state coastal zone management consistency
4
concurrence must be obtained, or a presumption of concurrence must occur (see 33 CFR 330.4(d)). The district
engineer or a State may require additional measures to ensure that the authorized activity is consistent with state
coastal zone management requirements.
23 . Reglonal and Case-By-Case Conditions. The activity must comply with any regional conditions that may
have been added by the Division Engineer (see 33 CFR 330.4(e)) and with any case specific conditions added by
the Corps or by the state, Indian Tribe, or U.S. EPA in Its section 401 Water Quality Certification, or by the state In
its Coastal Zone Management Act consistency determination .
24. Use of Multiple Nationwide Permits. The use of more than one NWP for a single and complete project is
prohibited, except when the acreage loss of waters of the United States authorized by the NWPs does not exceed
the acreage limit of the NWP with the highest specified acreage limit. For example, If a road crossing, over tldal
waters is constructed under NWP 14 , wilh as·sociated bank stabilization authorized by NWP 13, the maximum
acreage loss of waters of the United States for the total project cannot exceed 1/3-acre.
25 . Transfer of Nationwide Permit Verifications. If the permittee sells the property associated with the
nationwide permit verification, the permittee may transfer the nationwide permit verification to the new owner by
submitting a letter to the appropriate Corps district office to validate the transfer . A copy of the nationwide permit
verification must be attached to the letter, and the letter must contain the following statement and signature:
"When the structures or work authorized by this nationwide permit are still in existence at the time the property is
transferred , the terms and conditions of this nationwide permit, includ ing any spec ial conditions , will continue to
be binding on the new owner(s) of the property. To validate the transfer of this nallonwide permit , and the
associated liabilities associated with compliance with its terms and conditions , have the transferee sign and date
below."
(Transferee}
(Date)
26. Compliance Certification. Each permittee who received the NWP verification from the Corps must submit a
signed certification regarding the completed work and any required mitigation. The certification form must be
forwarded by the Corps with the NWP verification letter and will Include :
(a) A statement that the authorized work was done In accordance with the NWP authorization , including any
general or specific conditions ;
(b) A statement that any required mitigation was completed In accordance with the permit conditions; and
(c) The signature of the permittee certifying the completion of the work and mitigation.
27. Pre-Construction Notification. (a) Timing . Where required by the terms of the NWP, the prospective
permittee must notify the district en9lneer by submitting a pre-construction notification (PCN) as early as possible .
The distr ict engineer must determine If the PCN Is complete wllhln 30 calendar days of the date of receipt and, as
a general rule, wlll request addltlonal Information necessary to make the PCN complete only once. However, If lhe
prospective permittee does not provide all of the requested Information , then the district engineer will notify the
prospective permittee that the PCN Is still Incomplete and the PCN review process will not commence until all of
the requested Information has been received by the district engineer. The prospective permittee shall not begin
the activity :
(1) Until notified in wri~ing by the district engineer that the activ ity may proceed under the NWP with any
special conditions imposed by the district or division engineer ; or
(2) If 45 calendar days have passed from the district engineer's receipt of the complete PCN and the
prospective permittee has not received written notice from the district or division engineer . However, If the
permittee was required to notify the Corps pursuant to general condition 17 that listed species or critical habitat
might be affected or in the vicinity of the project, or to notify the Corps pursuant to general condition 18 that the
activity may have the potential to cause effects to historic properties, the permittee cannot begin the activity unlil
receiving written notification · from the Corps that is "no effect" on listed species or "no potential to cause effects"
on historic properties, or that any consultation required under Section 7 of the Endangered Species Act (see 33
CFR 330.4(f)} and/or Section 106 of the National Historic Preservation {see 33 CFR 330.4(g)) is completed. Also ,
work cannot begin under NWPs 21, 49, or 50 until the permittee has received wr itten approva l from the Corps . If
the proposed activity requires a written waiver to exceed specified limits of an NWP, the permlttee cannot begin
5
the activity until the district engineer issues the wa iver . If the district or division engineer notifies the permlttee in
writing that an individual permit is required within 45 calendar days of receipt of a complete PCN , the permittee
cannot begin the activity until an individual permit has been obtained . Subsequently, the permiltee's right to
proceed under !he NWP may be modified , suspended, or revoked only in accordance with the procedure set forth
in 33 CFR 330.5(d)(2).
(b) Contents of Pre-Construction Notificat ion: The PCN must be in writing and include the following
information :
(1) Name, address and telephone numbers of the prospective permittee ;
(2) Location of the proposed project;
(3) A description of the proposed project ; the project's purpose ; direct and indirect adverse env ironmental
effects the project would cause; any other NWP(s), regional general permit(s), or individual permlt(s) used or
intended to be used to authorize any part of the proposed project or any related activity. The description should
be sufficiently detailed to allow the district engineer to determine that the adverse effects of the project will be
minimal and to determine the need for compensatory mitigation. Sketches should be provided when necessary to
show that the activity complies with the terms of the NWP . (Sketches usually clarify the project and when provided
results in a quicker decision .);
(4) The PCN must include a delineation of special aquatic sites and other waters of the United States on
the project site . Wetland delineations must be prepared In accordance with the current method requ ired by the
Corps. The permittee may ask the Corps to delineate the special aquatic sites and other waters of the United
States, but there may be a delay if the Corps does the dellneallon , especially if the project site is large or contains
many waters of the United States . Furthermore, the 45 day period will not start until the delineation has been
submitted to or completed by the Corps, where appropriate ;
(5) ff the proposed activity will resu lt in the loss of greater than 1/1 O acre of wetlands and a PCN Is
required , the prospective permi!tee must submit a statement describ ing how the mitigation requirement wlfl be
satisfied . As an alternative, the prospective perml!tee may submit a conceptual or detailed mitigation plan .
(6) If any listed species or designated critical habitat might be affected or is in the vicin ity of the project , or
if the proj ect is located in designated critical habitat , for non-Federal applicants the PCN must include the name(s)
of those endangered or threatened species that might be affected by the proposed work or utllize the designated
critical hab itat that may be affected by the proposed work . Federal applicants must provide documentation
demonstrating compliance with the Endangered Species Act; and
(7) For an activity that may affect a historic property listed on , determined to be elig ible for fis ti ng on, or
potentially eligible fo r fisting on, the NaUonal Register of Historic Places, for non-Federal applfcants the PCN must
state wh ich historic property may be affected by the proposed work or include a vicinity map Indicating the
location of the historic property. Federal applicants must prov ide documentation demonstrating compliance wi th
Section 106 of the National Historic Preservation Act.
(c) Form of Pre -Construction Notification : The standard individual permit appl ication form (Form ENG 4345)
may be used , but the completed application form must clearly indicate that it is a PCN and must Include all of the
informa ti on required in paragraphs (b}(1) through (7) of this general condition . A letter conta ining the requ ired
information may also be used ..
(d) Agency Coordination : (1) The district engineer will consider any comments from Federal and state
agencies ~oncerning the proposed activity's compliance with the terms and conditions of the NWPs and the need
for mitigation to reduce the project's adverse environmental effects to a minima l level.
(2) For all NWP 48 activities requir ing pre-construction notification and for other NWP activities requiring
pre -construction notification to the district engineer that result in the loss of greater than 1/2-acre of waters of the
United States, the district engineer will immediately provide (e.g ., via facsimile transmission, overnight mail, or
other expeditious manner) a copy of the PCN to the appropriate Federal or state offices (U .S. FWS, state natural
resource or water quality agency, EPA, State Historic Preservation Officer (SHPO) or Tribal Historic Preservation
Office (THPO), and, If appropriate, the NMFS). With the exception of NWP 37 , these agencies will then have 10
calendar days from the date the material is transmitted to telephone or fax the district engineer notice that they
intend to provide substantive, site -specific comments . If so contacted by an agency, the district engineer will wait
an additional 15 calendar days before making a decision on the pre-construction notification. The district engineer
will fully consider agency comments received within the specified time frame, but will provide no response to the
resource agency , except as provided below. The distric t engineer will indicate In the administrative record
associated with each pre-construction notification that the resource agencies ' concerns were cons idered . For
NWP 37 , the emergency watershed protection and rehabilitation activity may proceed immediately in cases where
there Is an unacceptable hazard to life or a significant loss of property or economic hardship will occur . The
district engineer will consider any comments received to decide whether the NWP 37 author ization should be
modified , suspended, or revoked in accordance wlth the procedures at 33 CFR 330.5.
6
(3) In cases of where the prospective permlttee is not a Federal agency, the district engineer will provide
a response to NMFS within 30 calendar days of receipt of any Essential Fish Habitat conservation
recommendations, as required by Section 305(b)(4)(B) of the Magnuson-Stevens Fishery Conservation and
Management Act.
(4) Applicants are encouraged to provide the Corps multiple copies of pre-construction notifications to
expedite agency coordination.
(5) For NWP 48 activities that require reporting, the district engineer will provide a copy of each report
within 10 calendar days of receipt to the appropriate regional office of the NMFS.
(e) District Engineer's Decision: In reviewing the PCN for the proposed activity, the district engineer will
determine whether the activity authorized by the NWP will result in more than minimal individual or cumulative
adverse environmental effects or may be contrary to the public interest. If the proposed activity requires a PCN
and will result in a loss of greater than 1 /1 o acre of wetlands, the prospective permittee should submit a mitigation
proposal with the PCN. Applicants may also propose compensatory mitigation for projects with smaller impacts.
The district engineer will consider any proposed compensatory mitigation the applicant has included in the
proposal in determining whether the net adverse environmental effects to the aquatic environment of the
proposed work are minimal. The compensatory mitigation proposal may be either conceptual or detaifed. If the
district engineer determines that the activ!ty complies with the terms and conditions of the NWP and that the
adverse effects on the aquatic environment are minlmal, after considering mitigation, the district engineer will
notify the permittee and include any conditions the district engineer deems necessary. The district engineer must
approve any compensatory mitigation proposal before the permittee commences work . If the prospective
permittee elects to submit a compensatory mitigation plan with the PCN, the district engineer will expeditiously
review the proposed compensatory mitigation plan. The district engineer must review the plan within 45 calendar
days of receiving a complete PCN and determine whether the proposed mitigation would ensure no more than
minimal adverse effects on the aquatic environment. If the net adverse effects of the project on the aquatic
environment (after consideration of the compensatory mitigation proposal) are determined by the district engineer
to be minimal, the district engineer will provide a timely written response to the applicant. The response will state
that the project can proceed under the terms and conditions of the NWP. If the district engineer determines that
the adverse effects of the proposed work are more than minimal, then the district engineer will notify the applicant
either :
(1) That the project does not qualify for authorization under the NWP and instruct the applicant on the
procedures to seek authorization under an individual permit;
(2) That the project is authorized under the NWP subject to the applicant's submission of a mitigation plan
that would reduce the adverse effects on the aquatic environment to the minimal level; or
(3) That the project is authorized under the NWP with specific modifications or conditions. Where the
district engineer determines that mitigation Is required to ensure no more than minimal adverse effects occur to
the aquatic environment, the activity will be authorized within the 45-day PCN period. The authorization will
Include the necessary conceptual or specific mltlgatlon or a requirement that the applicant submit a mitigation
plan that would reduce the adverse effects on the aquatic environment to the minimal level. When mitigation is
required, no work in waters of the United States may occur until the district engineer has approved a specific
mitigation plan. ·
28. Sing le and Complete Project. The activity must be a single and complete project. The same NWP cannot be
used more than once for the same single and complete project.
Further Information
1. District Engineers have authority to determine if an activity complies with the terms and conditlons of an NWP.
2. NWPs do not obviate the need to obtain other federal, state, or local permits, approvals, or authorizations
required by law.
3. NWPs do not grant any property rights or exclusive privileges.
4. NWPs do not authorize any injury to the property or rights of others .
5. NWPs do not authorize interference with any existing or proposed Federal project.
Definitions
Best management practices (BMPs): Policies, practices, procedures, or structures implemented to mitigate the
adverse environmental effects on surface water quality resulting from development. BMPs are categorized as
structural or non-structural.
7
Compensatory mitigation: The restoration, establishment (creation), enhancement, or preservation of aquatic
resources for lhe purpose of compensating for unavoidable adverse impacts which remain after all appropriate
and practicable avoidance and minimization has been achieved .
Currently serviceable: Useable as is or with some maintenance , but not so _degraded as to essentlally require
reconstruction.
Discharge: The term "discharge" means any discharge of dredged or fill material and any activity that causes or
results in such a discharge.
Enhancement: The manipulation of the physical, chemical, or biological characteristics of an aquatic resource to
heighten, intensify, or improve a specific aquatic resource functlon(s). Enhancement results in the gain of selected
aquatic resource functlon(s), but may also lead to a decline In other aquatic resource function(s). Enhancement
does not result in a gain In aquatic resource area.
Ephemeral stream: An ephemeral stream has flowing water only during, and for a short duration after,
precipitation events in a typical year. Ephemeral stream beds are located above the water table yeaHound.
Groundwater Is not a source of water for the stream. Runoff from rainfall is the primary source of water for stream
flow .
Establishment (creation): The manipulation of the physical, chemical, or blologlcal characteristics present to
develop an aquatic resource that did not previously exist at an upland site. Establishment results in a gain in
aquatic resource area.
Historic Property: Any prehistoric or historic district, site (including archaeological site), building, structure, or
other object included in, or eligible for inclusion in, the National Reglster of Histor ic Places maintained by the
Secretary of the Interior. This term includes artifacts, records, and remains that are related to and located within
such properties . The term includes properties of traditional religious and cultural importance to an Indian tribe or
Native Hawaiian organization and that meet the National Register criteria (36 CFR Part 60).
Independent utility: A test to determine what constitutes a single and complete project in the Corps regulatory
program . A project is considered to have Independent utility If It would be constructed absent the construction of
other projects in the project area. Portions of a multi-phase project that depend upon other phases of the project
do not h~ve independent utility. Phases of a project that would be constructed even if the other phases were not
built can be considered as separate single and complete projects with Independent utility.
Intermittent stream: An Intermittent stream has flowing water during certain times of the year, when groundwater
provides water for stream flow. During dry periods, Intermittent streams may not have flowing water . Runoff from
rainfall is a supplemental source of water for stream flow .
Loss of waters of the United States: Waters of the United States that are permanently adversely affected by
filling, flooding, excavation, or drainage because of the regulated activity. Permanent adverse effects include
permanent discharges of dredged or fill material that change an aquatic area to dry land, increase the bottom
elevation of a waterbody, or change the use of a waterbody. The acreage of loss of waters of the United States Is
a threshold measurement of the impact to jurisdictional waters for determining whether a project may qualify for
an NWP; it is not a net threshold that is calculated after considering compensatory mitigation that may be used to
offset losses of aquatic functions and services. The loss of stream bed includes the linear feet of stream bed that
is filled or excavated . Waters of the United States temporarily filled, flooded, excavated, or drained, but restored
to pre-construction contours and elevations after construction, are not included in the measurement of loss of
waters of the United States. Impacts resulting from actlvitfes eligible for exemptions under Section 404(f) of the
Clean Water Act are not considered when calculating the loss of waters of the United States .
Non-tidal wetland: A non-tidal wetland Is a wetland that is not subject to the ebb and flow of tidal waters. The
definition of a wetland can be found at 33 CFR 328.3(b). Non-tidal wetlands contiguous to tidal waters are located
landward of the high tide line (I.e., spring high tide llne).
Open water: For purposes of the NWPs, an open-water Is any area that in a year with normal patterns of
precipitation has water flowing or standing above ground to the extent that an ordinary high water mark can be
determined. Aquatic vegetation within the area of standing or flowing water is either non-emergent, sparse; or
absent. Vegetated shallows are considered to be open waters . Examples of "open waters" include rivers ,
streams, lakes, and ponds .
Ordinary High Water Mark: An ordinary high water mark is a line on the shore established by the fluctuations of
water and indicated by physical characteristics, or by other appropriate means that consider the characteristics of
the surrounding areas (see 33 CFR 328 .3(e)).
Perennial stream: A perennial stream has flowing water year-round during a typical year. The water table ls
located above the stream bed for most of the year. Groundwater is the primary source of water for stream flow.
Runoff from rainfall is a supplemental source of water for stream flow.
Practicable: Available and capable of being done after taking into consideration cost, existing technology, and
logistics in light of overall project purposes.
8
Pre-construction notification: A request submitted by the project proponent to the Corps for confirmation that a
particular activity Is authorized by nationwide permit. The request may be a perm it application, letter, or simlla(
document that Includes information about the proposed work and its anticipated environmental effects . Pre-
construction notification may be required by the terms and conditions of a nationwide permit , or by regional
conditions . A pre -conslruction notification may be voluntarlly submitted In cases where pre-construction
notification is not required and the project proponent wants confirmation that the activity Is authorized by
nationwide permit.
Preservation: The removal of a threat to, or preventing the decline of, aquatic resources by an action in or near
those aquatic resources . This term Includes activities commonly associated with the protection and maintenance
of aquatic resources through the implementation of appropriate legal and physical mechanisms . Preservation
does not result in a gain of aquatic resource area or functions.
· Re-establishment: The manipulation of the physical, chemical, or biological characteristics of a site with the goal
of return ing natural/historic functions to a former aquatic resource. Re -establishment results In rebuilding a former
aquatic resource and results in a gain in aquatic resource area.
Rehabllltatlon : The manipulation of the physical , chemical, or biological characteristics of a site with the goal of
repairing natural/historic functions to a degraded aquatic resource . Rehabilitation results in a gain in aquatic
resource function, but does not result In a gain in aquatic resource area.
Restoration: The manipulation of the physical, chemical , or biological characteristics of a site with the goal of
returning naturallhlstorlc functions to a former or degraded aquatic resource. For the purpose of track ing net gains
in aquatic resource area, restoration is divided into two categories: Re-establishment and rehabilitation .
Rlffle and pool complex: Riffle and pool complexes are special aquatic sites under the 404(b)(1) Guidelines.
Riffle and pool complexes sometimes characterize steep gradient sections of streams. Such stream sections are
recognizable by their hydraulic characteristics. The rapid movement of water over a course substrate Jn riffles
results in a rough flow, a turbulent surface, and high dissolved oxygen levels In the water. Pools are deeper areas
associated with riffles . A slower stream velocity, a streaming flow, a smooth surface , and a finer substrate ·
characterize pools.
Riparian areas: Riparian areas are lands adjacent to streams, lakes, and estuar ine -marine shorelines. Riparian
areas are transitional between terrestrial and aquatic ecosystems, through which surface and subsurface
hydrology connects waterbodies with their adjacent uplands . Riparian areas provide a variety of ecological
functions and services and help improve or maintain local water quality. (See general condition 20.)
Shellflsh seeding: The placement of shellfish seed and/or suitable substrate to increase shellfish production.
Shellfish seed consists of immature individual shellfish or Individual shellfish attached to shells or shell fragments
(i.e., spat on shell). Suitable substrate may consist of shellfish shells, shell fragments , or other appropriate
materials placed into waters for shellfish habitat.
Single and complete project: The term "single and complete project" is defined at 33 CFR 330 .2(i) as the total
project proposed or accomplfshed by one owner/developer or partnership or other association of
owners/developers. A single and complete project must have independent utility (see definition). For linear
projects, a "single and complete project" is all crossings of a slngle water of the United States (I .e., a single
waterbody) at a specific location. For linear projects crossing a single waterbody several times at separate and
distant locations, each crossing is considered a slngle and complete project. However, Individual channels in a
braided stream or river , or individual arms of a large, Irregularly shaped wetland or lake, etc., are not separate
waterbodies, and cross ings of such features cannot be considered separately.
Stormwater management: Stormwater management Is the mechanism for controlling stormwater runoff for the
pu rposes of reducing downstream erosion, water quallly degradation, and flooding and mitigating the adverse
effects of changes in land use on the aquatic environment.
Stormwater management facilities: Stormwater management facilities are those facilities, including but not
limited to , stormwater retention and detention ponds and best management practices, which retain water for a
perlod-otilme to control runoff and/or improve the quality (i.e., by reducing the concentration of nutrients,
sediments, hazardous substances and other pollutants) of stormwater runoff.
Stream bed: The substrate of the stream channel between the ordinary high water marks. The substrate may be
bedrock or inorganic particles that range in size from clay to boulders . Wetlands contiguous to the stream bed , but
outside of the ordinary high water marks, are not considered part of the stream bed .
Stream channelization: The manipulation of a stream's course, condition, capacity, or location that causes more
than minima l interruption of normal stream processes . A channelized stream remains a water of the Un ited
States .
Structure : An object that is arranged in a definite pattern of organization. Examples of structures Include, without
limitation, any pier, boat dock, boat ramp, wharf, dolphin, weir, boom, breakwater, bulkhead, revetment , riprap,
jetty, artific ial Island, artificial reef, permanent mooring structure, power transmission line, permanently moored
floating vessel, plling , aid to navigation, or ·any other manmade obstacle or obstruction .
9
Tidal wetland : A tidal wetland is a wetland (i.e ., water of the United States) that is inundated by tidal waters . The
definitions of a wetland and tidal waters can be found at 33 CFR 328.3(b) and 33 CFR 328.3(f), respectively. Tidal
waters rise and fall in a predictable and measurable rhythm or cycle due to the gravitational pulls of the moon and
sun . Tidal waters end where the rise and fall of the water surface can no longer be practically measured in a
predictable rhythm due to masking by other waters , wind, or other effects. Tida l wetlands are located channelward
of the high tide line , which Is defined at 33 CFR 328 .3(d).
Vegetated shallows : Vegetated shallows are special aquatic sites under the 404(b)(1) Gu idelines . They are .
areas that are permanently Inundated and under normal circumstances have rooted aquat ic vegetation, such as
seagrasses in marine and estuarine systems and a variety of vascu lar rooted plants in freshwater systems.
Waterbody: For purposes of the NWPs, a waterbody Is a jurisdictional water of the United States that , during a
year with normal pat terns of precipitation, has water flow ing or standing above ground to the extent that an
ordinary high water ma rk (OHWM) or other Ind icators of jurisdiction can be dete rmined , as well as any wetland
area {see 33 CFR 328 .3(b)). If a jurisdictional wetland is adjacent--meaning border ing, contiguous , or
neighboring--to a jurisdictional waterbody displaying an OHWM or other indicators of jurisd iction, that wate rbody
and its adj acent wetlands are considered together as a single aquatic unit (see 33 CFR 328.4(c)(2)}. Examples of
"waterbod ies" include streams, rivers, lakes, ponds , and wetlands .

Linear Transportation Projects
Effective Date: March 19, 2007
(NWP Final Notice, 72 FR 11181, para. 3)
L:lnear Transportation Projects. Activities required for the construction , expansion, modification, or improvement
of linear transportation projects (e.g., roads, highways, railways, trails, airport runways, and taxiways) in waters of
the United States. For linear transportation projects in non-tidal waters, the discharge cannot cause the loss of
greater than 1/2-acre of waters of the United States. For linear transportation projects in tidal waters, the discharge
cannot cause the loss of greater than 1 /3 -acre of waters of the United States. Any stream channel modification,
including bank stablllzatlon , Is limited to the minimum necessary to construct or protect the llnear transportation
project; such modificatlons must be in the immediate vicinity of the project. ·
This NWP also authorizes temporary structures, fills, and work necessary to construct the linear transportation
project. Appropriate measures must be taken to maintain normal downstream flows and minimize flooding to the
maximum extent practicable, when temporary structures, work, and discharges, including cofferdams, are
necessary for construction activities, access fills, or dewaterlng of construction sites . Temporary fills must consist of
materials, and be placed in a manner, that will not be eroded by expected high flows. Temporary fills must be
removed in their entirety and the affected areas returned to pre-construction elevations. The areas affected by
temporary fills must be revegetated, as appropriate. .
This NWP cannot be used to authorize non-linear features commonly associated with transportation projects,
such as vehicle maintenance or storage buildings , parking lots, train stations , or aircraft hangars.
Notification: The permlttee must submit a pre-construction notification to the district engineer prior to
commencing the activity If: (1) the loss of waters of the United States exceeds 1/10 acre; or (2) there is a discharge
in a special aquatic site, Including wetlands . (See general condition 27 .) (Sections 10 and 404)
Note: Some discharges for the constructlon of farm roads or forest roads, or temporary roads for moving mining
equipment, may qualify for an exemption under Section 404(f) of the Clean Water Act (see 33 CFR 323.4).

installed and maintained at the permittee's expense on authorized fac ilities in navigable waters of the United States .
(c) The permittee understands and agrees that, if future operations by the United States require the removal,
relocation, or other alteration , of. the structure or work herein authorized , or if, in the opinion of the Secretary of the
Army or his authorized representative , said structure or work shall cause unreasonable obstruction to the free
navigation of the navigable waters, the permittee will be required, upo!J due notice from the Corps of Engineers, to
remove, relocate, or alter the structural work or obstructions caused thereby, without expense to the United States.
No claim shall be made against the United States on account of any such removal or alteration.
2. Aquatic Life Movements. No activity may substantially disrupt the necessary life cycle movements of those
species of aquatic life indigenous to the waterbody, including those species that normally migrate through the area,
unless the activity's primary purpose is to impound water. Culverts placed In streams must be installed to maintain
low flow conditions. ·
3. Spawning Areas. Activities In spawning areas during spawning seasons must be avoided to the maximum
extent practicable. Activities that result in the physical destruction (e .g., through excavation, fill, or downstream
smothering by substantial turbidity) of an important spawning area are not authorized .
4. Migratory Bird Breeding Areas. Activities in waters of the United States that serve as breeding areas for
migratory birds must be avoided to the maximum extent practicable .
5. Shellfish Beds . No activity may occur in areas of concentrated shellfish populations, unless the activity is
directly related to a shellfish harvesting activity authorized by NWPs 4 and 48.
6. Suitable Materlal. No activity may use unsuitable material (e.g ., trash, debris, car bodies, asphalt, etc.). Materlal
used for construction or discharged must be free from toxic pollutants in toxic amounts (see Section 307 of the
Clean Water Act).
7. Water Supply Intakes. No activity may occur In the proximity of a public water supply intake, except where the
activity is for the repair or improvement of public water supply intake structures or adjacent bank stabilization .
8. Adverse Effects From Impoundments. If the activity creates an impoundment of water, adverse effects to the
aquatic system due to accelerating the passage of water, and/or restricting its flow must be minimized to the
maximum extent practicable .
9. Management of Water Flows. To the maximum extent practicable , the pre-construction course, condition,
capacity , and location of open waters must be maintained for each activity, Including stream channelization and
storm water management activities , except as provided below. The activity must be constructed to withstand
expected high flows . The activity must not restrict or impede the passage of normal or high flows , unless the
primary purpose of the activity is to Impound water or manage high flows . The activity may alter the pre-
construction course, condition, capacity, and location of open waters if it benefits the aquatic environment (e .g.,
stream restoration or relocation activities).
10. Fiiis Within 100-Year Floodplains . The activity must comply with applicable FEMA-approved state or focal

ensure public safety .
15. Wild and Scenic Rivers . No activity may occur in a component of the National Wild and Scenic River System,
or in a river officially designated by Congress as a "study river" for possible inclusion in the system while the river
is in an official study status, unless the appropriate Federal agency with direct management responsibility for such
river, has determined in wr iting that the proposed activity will not adversely affect the Wild and Scenic River
designation or study status. Information on Wild and Scenic Rivers may be obtained from the appropriate Federal
land management agency in the area (e .g .. National Park Service, U.S. Forest Service, Bureau of Land
Management , U.S . Fish and Wildlife Service).
16. Tribal Rights . No activity or its operation may impair reserved tribal rights , including, but not limited to,
reserved water rights and treaty fishing and hunting rights.
17. Endangered Species. (a) No activity is authorized under any_ NWP which is llkely to jeop.ardize the continued
existence of a threatened authorized under any NWP which "may affect" a fisted or endangered species or a
species proposed for such designaUon, as identified under the Federal Endangered Species Act (ESA), or which
will destroy or adversely modify the critical habitat of such species . No activity is species or critical habitat, unless
Section 7 consultation addressing the effects of the proposed act ivity has been completed .
(b) Federal agencies should follow their own procedures for complying with the requirements of the ESA.
Federal permiltees must provide the district engineer with the appropr iate documentation to demonstrate
compliance with those requirements. ·
(c) Non-federal permitlees shall notify the district engineer if-any listed species or designated critical habitat
might be affected or is in the vicinity of the project, or if the project is located in designated critical habitat, and shall
not begin work on the activity until notified by the district engineer that the requirements of the ESA have been
2
satisfied and that the activity ls authorized. For activltles that might affect Federally -listed endangered or threatened
species or designated critical habitat, the pre-construction notification must include the name(s) of the endangered
or threatened speclei; that may be affected by the proposed work or that utilize the designated critical habitat that
may be affected by the proposed work . The district eng ineer will determine whether the proposed activity "may
affect" or will have "no effect" to listed species and designated critical habitat and will notify the non-Federal
applicant of the Corps' determination within 45 days of receipt of a complete pre-construction notification . In cases
where the non-Federal applicant has Identified listed species or crltfcal habitat that might be affected or is In the
vicinity of the project , and has so notified the Corps, the applicant shall not begin work untll the Corps has provided
notification the proposed actlvltles will have '"no effect" on listed species or critical habitat, or until Sec ti on 7
consultation has been completed .
(d) As a result of formal or informal consultation with the FWS or NMFS the distr ict enginee r may add species -
specific reglonal endangered spec ies conditions to the NWPs .
(e) Authorization of an activity by a NWP does not authorize the "lake" of a threatened or endangered species
as defined under the ESA . In the absence of separate authorization (e.g ., an ESA Section 10 Permit , a Biological
Opinion with ''incidental take" provisions, etc.) from the U.S . FWS or the NMFS , both lethal and non -lethal "takes "
of protected species are In violation of the ESA. Information on the location of threatened and endangered species
and their cri tical habitat can be obtained directly from the offices of the U.S . FWS and NMFS or their worldwide
Web pages at http ://www .fws.gov/ and http ://www .noaa .gov/fisheries.html respectively .
18. Historic Properties . (a) In cases where the district engineer determines that the activity may affect properties
li sted, or elig lblafor listing, in the National Reg ister of Histor ic Places, the activ ity is not authorized , until the
requirements of Section 106 of the National Historic Preservation Act (NHPA) have been sat isfied .
(b} Federal permittees should follow their own procedures for comply ing with the requ irements of Section 106
of the National Historic Preservation Act. Federal permittees must prov ide the distr ict engineer with the appropriate
documentation to demonstrate compliance with those requ irements .
(c) Non-federal permittees must submit a pre-construction notification to the district engineer if the authorized
activity may have the potential to cause effects to any historic properties listed, determined to be eligible for listing
on, or potentially eligible for listing on the National Register of Historic Places, Including previously unidentified
properties. For such activities, the pre-construction notification must state which historic properties may be affected
by the proposed work or Include a vicinity map Indicating the location of the historic properties or the potential for
the presence of historic properties. Asslstance regarding Information on the location of or potential for the presence
of historic resources can be sought from the State Historic Preservation Officer or Tribal Historic Preservation
Officer , as appropriate , and the National Register of Historic Places (see 33 CFR 330.4(g)). The district engineer
shall make a reasonable and good fa lth effort to carry out appropriate Identification efforts, which may include
background research, consultation , oral history lntervlews , sample field investigation , and field survey . Based on
the informat ion submitted and these efforts , the district engineer shall determine whether the proposed activity has
the potential to cause an effect on the historic properties. Where the non-Federal applicant has Identified historic
properties which the activity may have the potential to cause effects and so notified the Corps, the non -Federal
applicant shall not begin the activity until notified by the district engineer either that the activity has no potential to
cause effects or that consultation under Section 106 of the NHPA has been completed .
(d) The district enginee r will notify the prospective permittee within 45 days of receipt of a complete pre-
construction notification whether NHPA Section 106 consultallon Is required. Sec ti on 106 consult<ition is not
required when the Corps determines that the activity does not have the potential to cause effects on historic
properties (see 36 CFR 800.3(a)}. If NHPA section 106 consultation Is required and will occur, the district eng ineer
will notify the non-Federal applicant that he or she cannot begin work until Sect ion 106 consultation is completed .
(e) Prospective permitlees should be aware that section 110k of the NHPA (16 U.S.C. 470h-2(k)) prevents the
Corps from granting a permit or other assistance to an applicant who, with intent to avoid the requirements of
Section 106 of the NHPA , has inten ti onally significantly adversely affected a historic property to which the permit
would rela te, or having legal power to prevent it, allowed such significant adverse effect to occur , unless the Corps ,
after consultation with the Advisory Council on Historic Preservation (ACHP), determines that circumstances justify
granting such assistance despite the adverse effect created or permitted by the appl icant. If circumstances justify
granting the assistance , the Corps is required to notify the ACHP and provide documentatlon specifying the
circumstances, explaining the degree of damage to the integrity of any historic properties affected, and proposed
mitigation . This documentation must include any views obtained from the applicant , SHPO!THPO , appropriate
lndlan tribes if the undertaking occurs on or affects historic properties on trlbal lands or affects properties of interest
to those tr ibes , and other parties known to have a legftlmate interest in the impacts to the permitted activ ity on
histor ic properties .

19. Designated Critical Resource Waters . Crit ical resource wate rs include, NOAA-des ignated marlne
sanctuaries, National Estuarine Research Reserves, state natural heritage sites , and outstand ing national resou rce
waters or other waters officially des ignated by a state as having part icu lar environmental or ecolog ical sign ificance
and identified by the dist rict engineer after notice and opportunity for public comment. The district engineer may
also designate addltlonal crltlcal resource waters after notice and opportunity for comment.
(a) Discharges of dredged or fill material into waters of the United States are not authorized by NWPs 7, 12, 14,
16, 17 , 21 , 29, 31 , 35 , 39 , 40 , 42 , 43, 44, 49, and 50 fo r any activity within, or directly affecting , critical resou rce
waters, Including wetlands adjacent to such wate rs.
(b) For NWPs 3, 8, 10, 13 , 15, 18, 19 , 22 , 23, 25, 27, 28, 30, 33 ,
34, 36, 37, and 38, notification is required in accordance wilh general condition 27, fo r any ac ti vity proposed ln the
designated critical resource waters including wetlands adj acent to those waters . The district engineer may
authorize activities under these NWPs only after it is determined that the Impacts to the critical resource waters wlll
be no more than minimal.
20 . Mitigation. The district engineer will consider the following factors when determining appropriate and
practicable mitigation necessary to ensure that adverse effects on the aquatic environment are minimal :
(a) The activity must be designed and constructed to avoid and minimize adverse effects, both temporary and
permanent , to wate rs of the United States to the maximum extent practicable at the project site (i.e ., on site).
(b) Mitigation In all Its forms (avoiding , minimizing, rectifying, reducing, or compensating) will be requ ired to the
extent necessary to ensure that the adverse effects to the aquatic environment are minimal.
(c) Compensatory mitigation at a minimum one-for-one ratio will be required for all wetland losses that exceed
1/10 acre and require pre-construction notification , unless the district engineer determ ines In wr iting that some
other form of mitigation would be more environmentally appropriate and provides a project-specific wa iver of this
requi remen t. For wetland losses of 1/1 O acre or less that require pre -construction notificatlon , the distr ict engineer
may determi ne on a case-by-case basis that compensatory mitigation is required to ensure that the actlv !ty results
in minimal adverse effects on the aquatic environment . Since the like li hood of success is greater and the impacts to
potentlally valuable uplands are reduced , wetland restoration should be the first compensatory mitigation option
considered . ·
(d) For losses of streams or other open waters that require pre-construction notification, the district engineer
may require compensatory mitigation , such as stream restorat ion , to ensure that the activity results In minima!
adverse effects on the aquatic env ironment.
(e) Compensatory mitigation will not be used to increase the acreage losses allowed by the acreage lim its of
the NWPs . For example , if an NWP has an acreage limit of 1/2 acre, ft cannot be used to authorlze any project
result ing in the Joss of greater than 1/2 acre of waters of the United States, even If compensatory mitigation is
provided that replaces or restores some of the lost waters . However , compensatory mitigation can and should be
used , as necessary, to ensure that a project already meeting the established acreage llm its also satisfies the
minimal impact requirement associated with the NWPs.
(f) Compensatory mitigation plans for projects In or near streams or other open waters will nonnally include a
requirement for the establishment, maintenance, and legal protection (e .g., conservation easements) of riparia n
areas next to open waters. In some cases, riparian areas may be the only compensatory mitigation required.
Riparian are<;is should consist of native species. The width of the required ripar ian area will address cjocumented
water quality or aquatic habitat loss concerns . Normally , the riparian area will be 25 to 50 feet wide on each side of
the stream , but the district engineer may require slightly wider riparian areas to address documented water qua li ty
or habitat loss concerns . 'Mlere both wetlands and open waters exist on the project site , the district eng fneer will
determ ine the appropriate compensatory mitigation (e .g., riparian areas and/or wetlands compensation) based on
what Is best for the aquatic environment on a watershed basis. In cases where riparian areas are determ fned to be
the most appropriate form of compensatory mitigation, the distr ict engineer may waive or reduce the requirement to
provide wetland compensatory mitigation for wetland losses .
(g) Permittees may propose the use of mitigation ban ks, in-lieu fee arrangements or sepa rate activity-specific
compensatory mitigation . In all cases, the mitigation provisions will specify the party responsible for accomplish ing
and/or complying with the mitigation plan.
(h)Where certain functions and services of waters of the United States are permanently adversely affected,
such as the convers ion of a forested or scrub-shrub wetland to a he rbaceous wetland fn a permanently maintained
utility line right-of-way , mitigation may be required to reduce the adverse effects of the project to the min imal level.
21 . Water Quallty. Where States and authorized Tr ibes , or EPA where applicab le, have not prev iously certified
compliance of an NWP with CWA Sect ion 401, Individual 401 Water Quality Certificat ion must be obta ined or
waived (see 33 CFR 330.4(c)). The district engineer or State or Tribe may requ ire additional water qua li ty
4
management measures to ensure that the authorized activ ity does not result In more than minimal degradation of
water quality .
22 . Coastal Zone Management. In coastal states where an NWP has not previously received a state coastal zone
management consistency concurrence, an individual state coastal zone management consistency concurrence
must be obtained, or a presumption of concurrence must occur (see 33 CFR 330.4(d)). The district engineer or a
State may require additional measures to ensure that the authorized activity ls cons istent with state coastal zone
management requirements.
23. Regional and Case -By-Case Conditions. The activity must comply with any regional cond itions that may have
been added by the Div ision Engineer (see 33 CFR 330.4(e)) and wit h any case specific cond itions added by the
Corps or by the state, Indian Tribe , or U.S. EPA in its section 401 Water Quality Certification , or by the state in its
Coastal Zone Management Act cons istency determination .
24. Use of Multiple Nationwide Permits. The use of more than one NWP for a single and complete project Is
prohibited, except when the acreage loss of waters of the United States authorized by the NWPs does not exceed
the acreage llmft of the NWP with the highest specified acreage ffmft. For example, If a road crossing , over tidal
waters Is constructed under NWP 14, with associated bank stabllizatlon authorized by NWP 13 , the maximum
acreage loss of waters of the United States for the total project cannot exceed 1/3-acre.
25. Transfer of Nationwide Permit Verifications. If the permittee se ll s the property associa ted with the
nationwlde permit verification, the permittee may transfer the nationwide permit verification to the new owner by
submitting a letter to the appropriate Corps district office to validate the transfer. A copy of the nat ionwide permit
ver ification must be attached to the letter, and the letter must contain the follow ing statement and signa ture:
"When the structures or work authorized by th is nationwide perm it are still in existence at the time the property is
transferred , the terms and conditions of this nationwide permit, including any special conditions , will continue to be
binding on the new owner(s) of the property. To validate the transfer of this nationwide perm it, and the assoc iated
liabilities associated with compliance with its terms and conditions, have the transferee sign and date be low."
(Transferee)
(Date)
26 . Compllanca Certification. Each perm fltee who rece ived the NWP verification from the Corps must submit a
signed certification regarding the completed work and any required mitigation . The certification form must be
forwarded by the Corps with the NWP verification letter and will include :
(a) A statement that the authorized work was done in accordance with the NWP authorization , inc luding any
general or specific conditions;
(b) A statement that any required mitigat ion was completed in acco rdance with the perm it cond iti ons ; and
(c) The signature of the permittee certify ing the completion of the work and mitigation .
27. Pre-Construction Notification. (a) Timing. Where required by the terms of the NWP, the prospective perm lttee
must notify the district engineer by submitting a pre-construction notification (PCN) as early as possible. The district
engineer must determine If the PCN Is complete within 30 calendar days of the date of receipt and, as a general
rule, will req uest addltlonal lnformation necessary to make the PCN complete only once . However, if the
prospective permittee does not provide all of the requested information , then the district engineer will notify the
prospective permittee that the PCN is still incomplete and the PCN review process will not commence until all of the
requested information has been received by the district engineer. The prospective permittee shall no t begin the
activity until either:
(1) He or she Is notified in writing by the district engineer that the activ ity may proceed under the NWP with
any special conditions imposed by the district or division engineer; or
{2) Forty-five calendar days have passed from the district engineer's receipt of the complete PCN and the
prospective permittee has not received written notice from the distr ict or division engineer. However, if the perm ittee
was required to notify the Corps pursuant to general condition 17 that listed species or critical hab itat might affected
or in the vicinity of the project, or to notify the Corps pursuant to general condition 18 that the activity may have the
potentia l to cause effects to historic properties , the permittee cannot begin the ac ti vity until receiving written
notification from the Corps that is "no effect " on listed species or "no potential to cause effects• on histor ic
5
properties, or that any consultation required under Section 7 of the Endangered Species Act (see 33 CFR 330.4(!))
and/or Secti on 106 of the Natlonal Historic Preservation (see 33 CFR 330.4(g)) is completed . Also, work cannot
begin under NWPs 21 , 49, or 50 until the permlttee has received written approval from the Corps. If the proposed
activity requires a written waiver to exceed specified limits of an NWP , the permittee cannot begin the activity until
the district engineer issues the waiver. If the district or division engineer notifies the permittee In writing that an
individual pe r mit is required within 45 calendar days of receipt of a complete PCN, the permittee cannot begin the
activity until an individual permit has been obtained . Subsequently, the permlltee's right to proceed under the NWP
may be modified, suspended, or revoked only in accordance with the procedure set forth in 33 CFR 330 .5{d}(2).
(b) Contents of Pre -Construction Notification: The PCN must be In writing and include the following information :
(1) Name, address and telephone numbers of the prospective permittee ;
(2) Location of the proposed project;
(3) A description of the proposed project; the project 's purpose; direct and indirect adverse env lronmental
effects the project would cause ; any other NWP(s), regional general permit(s). or individual permlt(s) used or
intended to be used to authorize any part of the proposed project or any related activity. The descriptfon should be
sufficiently detailed to allow the distr ict engineer to determine that the adverse effects of the project will be minimal
and to determ ine the need for compensatory mitigation . Sketches should be prov ided when necessary to show that
the activity complies with the terms of the NWP. (Sketches usually clar ify the project and when provided result in a
qu icker decision.);
{4) The PCN must include a delineation of special aquatic sites and other waters of the United States on
the project site . Wetland delineations must be prepared in accordance with the cu rrent method required by the
Corps. The permittee may ask the Corps to delineate the special aquatic sites and other wate rs of the United
States, but there may be a delay if the Corps does the de li neation, especially if the project site is large or contains
many waters of the Un ited States . Furthermore, the 45 day period will not start until the delineation has been
submitted to or completed by the Corps , where appropriate ;
(5) If the proposed activity will result In the loss of greater than 1/10 acre of wetlands and a PCN is
required , the prospective permittee must submit a statement describing how the mitigation requirement will be
satisfied . As an alternative, the prospectlve permlttee may submit a conceptual or detailed mitigation plan .
(6) If any listed species or designated critical habitat might be affected or is in the vicinity of the project , or if
the project is located in designated critical habitat, for non -Federal applicants the PCN must include the name(s) of
those endangered or threatened species that might be affected by the proposed work or utilize the des ignated
critical hab itat that may be affected by the proposed work. Federal applicants mus t provide documentation
demonstrat ing compliance with the Endangered Species Act; and
(7) For an actlvity that may affect a historic property listed on , determined to be eligible for listing on , or
potentially eligible for listing on, the National Register of Historic Places , for non-Federal applicants the PCN must
state which historic property may be affected by the proposed work or include a vicinity map indicating the location
of the histor ic property. Federal applicants must provide documentation demonstrating compliance with Section 106
of the National Historic Preservation Act.
(c) Form of Pre -Construction Notification: The standard individual permit application form (Form ENG 4345)
may be used , but the completed application form must clearly indicate that It is a PCN and must include all of the
information required in paragraphs (b)(1) through (7) of this general condition. A letter contain ing the required
information may also be used .
(d) Agency Coordination: (1) The district eng ineer will consider any comments from Federal and state agencies
concern ing the proposed activity's compliance with the terms and conditions of the NWPs and the need for
mitigation to reduce the project's adverse environmental effects to a minimal level.
(2) For all NWP 48 activities requiring pre-construction notification and for other NWP activities requiring
pre -construc ti on notification to the district engineer that result In the loss of greater than 1 /2 -acre of waters of the
United States, the district engineer will immediately provide (e .g., via facsimile transmission , overn ight mail, or other
expeditious manner) a copy of the PCN to the appropriate Federal or state offices (U.S. FWS , state natural
resource or water quality agency, EPA, State Historic Preservation Officer (SHPO) or Tribal Historic Preservation
Office (THPO), and, If appropriate , the NMFS). With the exception of NWP 37, these agencies will then have 1 O
calendar days from the date the material is transmitted to telephone or fax the distr ict engineer notice that they
Intend to provide substantive, site -specific comments . If so contacted by an agency, the district engineer will wait an
additional 15 calendar days before making a decision on the pre-construction notification . The district engineer will
fully cons ider agency comments received with in the specified time frame, but will provide no response to the
resource agency, except as provided below. The district engineer will ind icate In the admin istrative record
associated with each pre-construction notification that the resource agencies' concerns were considered . For NWP
37, the emergency watershed protection and rehabilitation activity may proceed immediate ly in cases where there
Is an unacceptable hazard to life or a significant loss of property or economic hardship will occur. The district
6
engineer will consider any comments received to dec ide whether the NWP 37 authoriza ti on should be modified ,
suspended, or revoked in accordance with the procedures at 33 CFR 330.5 .
(3) In cases of where the prospective permlltee is not a Federal agency, the district engineer will provide a
response to NMFS with in 30 calendar days of rece ipt of any Essential Fish Habitat conservation recommendations ,
as required by Section 305(b)(4)(8) of the Magnuson -Stevens Fishery Conservation and Management Act.
(4) Applicants are encouraged to provide the Corps multlple copies of pre-construction notifications to
expedite agency coordination.
(5) For NWP 48 activities that require reporting , the district engineer will provide a copy of each report
within 10 calendar days of receipt to the appropriate reg lonal office of the NMFS .
(e) District Engineer's Decision : In reviewing the PCN for the proposed activity, the district engineer will
determine whether the activity authorized by the NWP will result in more than min imal individual or cumulative
adverse environmental effects or may be contrary to the public interest. If the proposed activ ity requ ires a PCN and
will result in a loss of greater than 1/10 acre of wetlands, the prospective permittee should submit a mitigation
proposal with the PCN. Applicants may also propose compensatory mitigation for projects with smaller Impacts.
The district eng ineer will consider any proposed compensatory mlUgat ion the applicant has Included in the proposal
in determining wh.ethe r the net adverse environmental effects to the aquatic environment of the proposed work are
minimal . The compensatory mitigation proposal may be either conceptual or detailed . ff the district engineer
determines that the activity complies with the terms and conditions of the NWP and that the adverse effects on the
aquatic environment are minimal , after considering mitigat ion, the district engineer will notify the pe rmittee and
Include any condltrons the district engineer deems necessary . The district engineer must approve any
compensatory mitigation proposal before the permittee commences work. If the prospective perm ittee elects to
submit a compensatory mitigation plan with the PCN, the district engineer will expeditiously review the proposed
compensatory mitigation plan. The district engineer must review the plan within 45 calendar days of receiving a
complete PCN and determine whether the proposed mit igation would ensure no more than min imal adverse effects
on the aquatic environment. If the net adverse effects of the project on the aquatic environment (after consideration
of the compensatory mitigation proposa l) are determined by the district engineer to be minimal , the district engineer
will provide a timely written response to the applicant. The response will state that the project can proceed under
the terms and conditions of the NWP . If the district engineer determines that the adverse effects of the proposed
work are more than minimal, then the district engineer will notify the applicant either :
(1) That the project does not qualify for authorization under the NWP and Instruct the applicant on the
procedures to seek authorization under an indiv idual perm it;
(2) that the project is authorized under the NWP subject to the applicant 's subm ission of a mitigation plan
that would reduce the adverse effects on the aquatic environment to the minimal level; or
(3) that the project is authorized under the NWP with specific modifications or cond itions . Where the district
engineer determines that mitigation is required to ensure no more than minimal adverse effects occur to the aquat ic
environment , the activity will be authorized within the 45-day PCN period. The authorization will include the
necessary conceptual or specific mitigation or a requirement that the applicant submit a mitigation plan that would
reduce the adverse effects on the aquatic environment to the minimal level. When mitigation is requ ired , no work in
waters of the United States may occur until the district eng ineer has approved a specific mitigation plan .
28 . Single and Complete Project. The activity must be a single and complete project. The same NWP cannot be
used more than once for the same single and complete project.
Further Information
1. District Engineers have authority to determine if an activity complies with the terms and co nditions of an NWP .
2 . NWPs do not obviate the need to obtain other federal, state, or local permits , approvals, or autho ri zations
required by law.
3. NWPs do not grant any property rights or exclusive privileges.
4 . NWPs do not authorize any Injury to the property or rights of others .
5. NWPs do not authorize interference with any existing or proposed Federal project.
Definitions
Best management practices (BMPs): Policies, practices, procedures , or structures implemented to mitigate the
adverse environmental effects on surface water quality resulting from development. BMPs are categorized as
structural or non-structural.
7
Compensatory mitigation : The restoration, establishment (creation), enhancement, or preservation of aquatic
resources for the purpose of compensating for unavoidable adverse Impacts which remain afte r all appropriate and
practicable avoidance and minimization has been achieved .
Currently serviceable : Useable as is or with some maintenance, but not so degraded as to essentially require
reconstruction.
Discharge: The term "discharge" means any discharge of dredged or fill material.
Enhancement: The manipulation of the physical, chemical , or biological characteristics of an aquatic resource to
heighten, intensify, or improve a specific aquatic resource function(s). Enhancement results in the gain of selected
aquatic resource functlon(s), but may also lead to a decline in other aquatic resource function(s). Enhancement
does not result In a gain in aquatic resource area . ·
Ephemeral stream: An ephemeral stream has flowing water only during, and for a short duration after, precipitation
events In a typical year. Ephemeral stream beds are located above the water table year-round . Groundwater is not
a source of water for the stream . Runoff from ra!nfall ls the primary source of water for stream flow.
Establishment (creation): The manipulation of the phys ical, chemical, or biological character istics present to
develop an aquatic resource that did not prevlously exist at an upland site . Establishment results In a gain in
aquatic resource area.
Historic Property: Any prehistoric or historic district, site (including archaeologlcal site), building, structure , or other
object included in, or ellglble for inclusion in, the National Register of Historic Places maintained by the Secretary of
the Interior. This term includes artifacts, records, and remains that are related to and located within such properties .
The term includes properties of traditional religious and cultural importance to an Indian tribe or Native Hawaiian
organization and that meet the National Register criteria (36 CFR Part 60).
Independent utlllty: A test to determine what constitutes a single and complete project in the Corps regulatory
program. A project Is considered to have independent utility if it would be constructed absent the construction of
other projects In the project area . Portions of a multi-phase project that depend upon other phases of the project do
not have independent utility. Phases of a project that would be constructed even if the other phases were not built
can be considered as separate single and complete projects with Independent utility.
Intermittent stream: An Intermittent stream has flowing water during certain times of the year, when groundwater
provides water for stream flow. During dry periods, intermittent streams may not have flowing water. Runoff from
rainfall is a supplemental source of water for stream flow.
Loss of waters of the United States: Waters of the United States that are permanently adversely affected by
filling, flooding, excavation, or drainage because of the regulated activity. Permanent adverse effects Include
permanent discharges of dredged or fill material that change an aquatic area to dry land, increase the bottom
elevatlon of a waterbody, or change the use of a waterbody. The acreage of loss of waters of the United States is a
threshold measurement of the impact to jurisdictional waters for determining whether a project may qualify for an
NWP; it is not a net threshold that is calculated after consfdering compensatory mitigation that may be used to
offset losses of aquatic functions and services. The Joss of stream bed includes the linear feet of stream bed that is
filled or excavated. Waters of the United States temporarily filled, flooded, excavated, or drained, but restored to
pre-construction contours and elevations after construction, are not included In the measurement of loss of waters
of the United States. Impacts resulting from acUvities eligible for exemptions under Section 404(1) of the Clean
Water Act are not considered when calculating the loss of waters of the United States.
Non-tldal wetland: A non-tidal wetland is a wetland that is not subject to the ebb and flow of tidal waters . The
definition of a wetland can be found at 33 CFR 328 .3(b). Non-tidal wetlands contiguous to tidal waters are located
landward of the high tide line (i .e., spring high tide line).
Open water: For purposes of the NWPs, an open-water is any area that in a year with normal patterns of
precipitation has water flowing or standing above ground to the extent that an ordinary high water mark can be
determined . Aquatic vegetation within the area of standing or flowing water Is either non-emergent, sparse , or
absent. Vegetated shallows are considered to be open waters . Examples of "open waters" include rivers, streams,
lakes, and ponds .
Ordinary High Water Mark: An ordinary high water mark is a line on the shore established by the fluctuations of
water and indicated by physical characteristics, or by other appropriate means that consider the characteristics of
the surrounding areas (see 33 CFR 328.3(e)).
Perennial stream: A perennial stream has flowing water year-round during a typical year. The water table is
located above the stream bed for most of the year. Groundwater is the primary source of water for stream flow.
Runoff from rainfall is a supplemental source of water for stream flow .
Practicable: Available and capable of being done after taking into consideration cost , existing technology, and
logistics in light of overall project purposes.
Pre-construction notification : A request submitted by the project proponent to the Corps for confirmation that a
particular activity is authorized by nationwide permit. The request may be a permit application, letter, or similar
document that fncludes information about the proposed work and its anticipated environmental effects. Pre-
8
construction notification may be required by the terms and conditions of a nationwide permit , or by regional
conditions. A pre-construction notification may be vo luntarily submitted in cases where pre-construction notification
is not required and the project proponent wants confirmation that the activity is authorized by nationwide permit.
Preservation: The removal of a threat to, or preventing the decline of, aquatic resources by an action in or near
those aquatic resources. This term includes activities commonly associated with the protection and maintenance of
aquatic resources through the implementation of appropriate legal and physical mechanisms . Preservation does
not result In a gain of aquatic resource area or functions.
Re-establishment: The manlpulalion of the physical, chemical, or biological characteristics of a site with the goal of
returning natural/historic functions to a former aquatic resource . Re-establishment results in rebuilding a former
aquatic resource and results in a gain in aquatic resource area.
Rehabilitation: The manipulation of the physical, chemical, or biological characterlstlcs of a site with the goal of
repairing natural/historic functions to a degraded aquatic resource. Rehabilitation results In a gain In aquatic
resource function, but does not result in a gain In aquatic resource area.
Restoration : The manlpulation of the physical, chemical, or biological characteristics of a site with the goal of
returning natural/historic functions to a former or degraded aquatic resource . For the purpose of tracking net gains
Jn aquatic resource area , restoration Is divided into two categories : Re -establishment and rehabilitation .
Riffle and pool complex: Riffle and pool complexes are special aquatic sites under the 404(b)(1) Guidelines . Riffle
and pool complexes sometimes characterize steep gradient sections of streams. Such stream sections are
recognizable by their hydraulic characteristics. The rapid movement of water over a course substrate in riffles
results in a rough flow, a turbulent surface, and high dissolved oxygen levels in the water. Pools are deeper areas
associated with riffles . A slower stream velocity , a streaming flow, a smooth surface, and a finer substrate
characterize pools .
Riparian areas: Ripar ian areas are lands adjacent to streams, lakes, and estuarine-marine shorelines . Riparian
areas are transitional between terrestrial and aquatic ecosystems, through which surface and subsurface hydrology
connects waterbodies with the ir adjacent uplands . Rlpar fan areas provide a variety of ecological functions and
services and help Improve or maintain local water quality . (See general condition 20.)
Shellfish seeding : The placement of shellfish seed and/or suitable substrate to increase shellfish production .
Shellfish seed consists of Immature individual shellfish or Individual shellfish attached to shells or shell fragments
(i.e., spat on shell}. Suitable substrate may consist of shellfish shells , shell fragments, or other appropriate
materials placed into waters for shellfish habitat.
Single and complete project: The term "slngle and complete project" is defined at 33 CFR 330.2(i} as the total
project proposed or accomplished by one owner/developer or partnership or other association of
owners/developers. A single and complete project must have independent utility (see definition). For linear projects ,
a "single and complete project" ls all crossings of a single water of the United States (i.e., a single waterbody) at a
specific location . For linear projects crossing a single waterbody several times at separate and distant locations ,
each crossing is considered a single and complete project. However, individual channels in a braided stream or
river, or individual arms of a large, irregularly shaped wetland or lake, etc., are not separate waterbodies, and
crossings of such features cannot be considered separately.
Stormwater management: Stormwater management Is the mechanism for controlling stormwater runoff for the
purposes of reducing downstream erosion, water quality degradation, and flooding and mitigating the adverse
effects of changes In land use on the aquatic environment.
Stormwater management facllltles: Stormwater management facilities are those facilities , including but not
l!m!ted to , stormwater retention and detention ponds and best management practices, which retain water for a
period of time to control runoff and/or improve the quality (i.e., by reducing the concentration of nutrients ,
sediments, hazardous substances and other pollutants) of stormwater runoff.
Stream bed: The substrate of the stream channel between the ordinary high water marks. The substrate may be
bedr.ock or inorganic particles that range in size from clay to boulders. Wetlands contiguous to the stream bed, but
outside of the ordinary high water marks , are not considered part of the stream bed.
Stream channelization: The manipulation of a stream's course, condition, capacity, or location that causes more
than minimal interruption of normal stream processes. A channelized stream remains a water of the United States .
Structure: An object that Is arranged In a definite pattern of organization. Examples of structures include, without
limitation, any pier, boat dock, boat ramp, wharf , dolphin , weir, boom , breakwater, bulkhead , revetment, rlprap,
jetty, artificial Island, artificial reef, permanent mooring structure, power transmission line, permanently moored
floating vessel, piling, aid to navigation, or any other manmade obstacle or obstrucllon.
Tidal wetland: A tidal wetland is a wetland (I.e ., water of the United States) that is inundated by tidal waters . The
definitions of a wetland and tidal waters can be found at 33 CFR 328.3(b) and 33 CFR 328.3(f}, respectively . Tidal
waters rise and fall in a predictable and measurable rhythm or cycle due to the gravitational pulls of the moon and
sun . Tidal waters end where the rise and fall of the water surface can no longer be practically measured in a
9
predictable rhythm due to masking by other waters, wind, or other effects . Tldal wetlands are located channelward
of the high tide line, which is defined at 33 CFR 328 .3(d).
Vegetated shallows: Vegetated shallows are special aquatic sites under the 404(b)(1) Guidelines . They are areas
that are permanently inundated and under normal circumstances have rooted aquatic vegetation, such as
seagrasses in marine and estuarine systems and a variety of vascular rooted plants in freshwater systems .
Waterbody : For purposes of the NWPs, a waterbody is a jurisdictional water of the United States that, during a
year with normal patterns of precipitation, has water flowing or standing above ground to the extent that an ordinary
high water mark (OHWM) or other indicators of jurisdiction can be determined, as well as any wetland area (see 33
CFR 328 .3(b)). If a jurisdictional wetland is adjacent--meanlng bordering, contiguous, or neighboring --to a
jurisdictional waterbody displaying an OHWM or other Indicators of jurisdiction, that waterbody and its adjacent
wetlands are considered together as a single aquatic unit (see 33 CFR 328.4(c)(2)). Examples of "waterbodies"
include streams, rivers, lakes, ponds, and wetlands .

Re: USACB .Nationwide Permits
Dear Ms. Sloan:
This letl·~r is in response to your April 3, 2007, letter requesting Clean Ware: Act Section 401 certification of the
United States Army Corps of Engineen (Coxps) Nationwide Permits (NWPs). The Final Notice ofReissuancc
of Nationwide Permits was published in the Federal Regjstq (Part II, Vol. 72, No. 47, pages 11092-11198) on
March 12, 2007 •. Proposed regional conditions for NWPs in Texas were proposed in an October 12, 2006
public notice.
~ Tex.as Commission on Enviro:nn,.ental Quality (TCEQ) has reviewed the Final Notice of Reissuance of
Nationwide Permits and the proposed regional conditions. On behalf of the _Executive Direetor and based on
our evaluation of the infonnation contained in these docwnents , the TCEQ certifies that the activities authorized
by NWPs 1, 2, 4, 5, &, 9, '10, 11, 20, 23, 24, 28, 34, 35, and 48 should not result in a violation of established
Tex.as Surface Water Quality Standards as required by Section 401 of the Federal 9Iean Water Act and pursuant
to Title 30, Texas Administrative Code, Chapter 279.
The TCEQ conditionally certifies 'that the activities authorized byNWPs 3, 6, 1, 12, 13, 14, 15, 17, 18, 19, 21,
22, 25, 27, 29, 30, 31, 32, 33, 36, 37, 38, 39, 40, 41~ 42, 43, 44, 45, 46, 47, 49, and 50 should not result in a
violation of established Texas Surface Water Quality ~1andards as required by Seotion'401 of the Federal Clean
Water Act and pursuant to Title 30, Texas Administrative Code, Chapter 279 . Conditions for each NWP are
defined in Enclosure 1 and mqre detail on specific conditions are discussed below... ·
The TCEQ understands that?-prohibition against the use of NWPs in coastal dune swales will be included in the
2007 Texas Regional Conditions (Regional Conditions) for certain NWPs consistent with the 2002 Texas
Regional Conditions. Inclusion of a prohibition of using NWPs in coastal dune swales is a condition of this 401
TCEQ certification. ·
The proluoition of sidecasting of materials was removed from NWP 41 in the 2007 NWP renewal. Jn the
November 28, 2006 TCEQ conunent letter to the Corps regarding the Regional Conditions for NWP 41, the
TCEQ requested the prohibition against the pennanent sidecasting of excavated materials into waters of the

U.S. be llicluded as a regional condition.. The TCBQ recommended that if the sidccasting i)rolu'bition is not .
included in the Regional Conditions, that a limit on the amomit of waters of the U.S. that can be impactM by the
si<jecastingt and a requirement for mitigation of thoso impacts be fucluded as a regional condition. If the Corps
chooses to not include a prolu"bition against sidecasting material in the Regional Conditions, the TCEQ
conditional certification of NWP 41 is that the area impacted by the sidecasting should not exceed 3 acres or
1500 linear feet For purposes of calculating tli.e threshold one acre of impact is considered equal to 500 linear
feel Inclusion of a probJ.'biti.on against the permanent sidecasting of material that impacts more then 3 acres or
1500 linear feet under NWP 41 is a condition of this 401 TCBQ certification.
In the N~vembez 28, 2006 TCBQ comment letter to the Corps regarding the Regio~ Concliti.ons for NWP 46
(previously NWP B), the TCEQ requested a regional condition for NWP 46 th/it contains an upper limit no
greater than 1,500 linur feet Inclusion of a limit no greater than 1,500 linear feet W1der NWP 46 is a condition
of this 401 TCEQ certification. · · ·
The TCEQ wants to clarify the application ofNWP 16 in Texas. NWP 16 sJ:iould be limited to the return water
from upland contained dredged material disposal areas. It is important to euipbasize the intent for dredged ·
material disposal. The TCEQ understands dredged material to be associated with navigational dredging
activitics1 not commercial mining activities. To avoid confusion the TCEQ requests that a. regional condition be
added that prolu"bits the u'se of NWP 16 for activities that would be regulated unckz Standard Industrial
Classifieati.on (SIC).c0des ·t442 and 1446 (industrial an.d cons.truotion sand and gravel mining) .. This condition
is also included as pa.rt of the 401 certifica~on of ?-fWP 16. ·
. .
The final NWP 16 states · that the quality of the return water is controlled by the state through the 401
certification procedures. Consistent with previous NWPs certification decisions the TCEQ ·is conditionally
certifying NWP 16 for the return water from confined upland disposal not to exceed a 300 mWL Total
Suspended Solids (TSS) concentration and request the Corps to include this condition in ~ Regional
Conditions. The TCEQ reeo~ the usefulness of having an instantaneous method to d~ compliance
wi~ the 300 mg/L TSS limit However, existing literature and analysis of paired Sa.mpl~ of turbidity and TSS
from the Texas Surface Water Quality Data indicate this relationship m~ be a site specific charactem.ation of
the actual sediments to be dredged. To address this approach we have included ;iew language in the NWP 16
conditional certification that allows flexi'bility to use an instantaneous method in implementing the TSS limit
when a site specific correlation curve for turbidity (nephelomelric tmbidity wtlta (NIU)) versus TSS has been
approved by TCEQ. The TCBQ remains interested ~ working with the Corps in the development of these
curves. We encourage the Corps to accept the conditional certification ofNWP 16 as a Regional Condition and
that we work together to find the best methodS to implement this limit
In evaluating this condition for the Regional Conditions for NWPs the TCEQ encourages the Corps to consider
that TSS limits are promulgated as effluent limits under Title 40 of the Code of Federal Regulations . The
TCEQ requirement to control return water from confined upland disposal n9t to exceed a 300 mgi'L TSS has
also been included in individual 404 permits. It is also important to note that the TCEQ effectively imposes

federal Clean Water Act
The TCEQ is conditionally certifying NWP General Condition #12 Soil Erosion and Sediment Controls, and
General Condition #21 Water Quality. The conditions address three broad categories of water quality
management with speoific recommendations for Best Management Practices (BMPs) for each cate.gory. These
BMPs are intended to enhance the water quality ptotCction of these General Conditions. A list of TCBQ-
recommended BMPs is included as Enclosure 2. Enclosure 3 is provided as a quick reference for all NWPs. A
detailed description of the B!vfi>s is provided in Enclosure 4. Runoff from bridge decks has been exempted
from the requirement for post-construction total suspended solids (TSS) controls under General Condition 21.
As stated in om April 3, 2007 letter to the Corps, the TCEQ would like to include these BMPa for the jirotection
of waters in the state specific to each NWP as part o~ the regional conditions for Texas.

wri~ approvals of waivers for impacts to ephemeral, intermittent or perennial streams. The TCEQ is
~ditionally certifying NWP 36 to ~uirc the Corps to copy TCBQ on all written waivers for discharges
greater than the 50 cubic yard limit or boat ramps greater than 20 feet in width. The TCEQ is also conditionally
certifying General Condition 20 Mitigation to require the Corps · to copy TCEQ on any written notification of a
mitigation waiver. In addition. TCBQ understands that a regional condition will be adde4 that requires
mitigation for streams and 8pecial aquatic sites, such as pools/riffles, seagrass, and mudflats that will adequately
comptnsa!e for their functions and values. The TCEQ is requesting this information to fulfill its respollSloility
to ensure water of the state is aP.propriately protected by understanding the impact of waivers being granted in
~. .
This certification decision is limited t~ those activities under the jurisdiction of the TCEQ. For aqtivities related
to the production and exploration of oil and gas a Texas Railroad Commission certification is required as
provided in the Texas Water Code §26.131.
The TCEQ has reviewed the Notice ofReissuance of Nationwide Permim for consistency with the goals and
policies of the Texas Coastal Management Program (CMP) in accordance with the regulations of the Coastal
C~rdination Council, 31 TAC §505.30, and has determined that the action is consistent with the applicabJe
CMP goals and policies.
This certification was reviewed for ~onsistenoy with the CMP's development in critical areas policy {31 TAC
§501.14(h)} and dredging and dredged material di8posal and placement policy {31 TAC §50l.14(j)}. This
certification complies with the CMP goals {31 TAC §501.12(1,2,3,5)} applic~ble to these policies.
The TCEQ reserves the right to modify this certification if additional information identifies specific areas where
significant impacts, including cumulative or secondary impacts, are occurring, and the use of these NWPs
would be inappropriate.

·Description of BMPs
EROSION CONTROL BMPs
Temporary Vegetation
Description: Vegetation can be used as a temporary or permanent stablllzation technique for areas
disturbed by construction. Vegetation effectively reduces erosion In swales, stockpiles, berms, mild
to medium slopes, and along roadways. Other techniques such as matting, mulches, and grading
· may be required to assist ~n the establishment of vegetation.
Materials:
• The type of temporary vegetation used on a site is a function of the .season ~nd the availability of
. water for Irrigation. ·
~ Temporary vegetation should be selected appropriately for the area.
• County agricultural extension agents are a good source for suggestions for temporary vegetation.
•All seed should be high quallty, U.S.-Dept. of Agriculture certified seed.
Install atton:
• Grading must be completed prior to seeding.
• Slopes should be minimized .
• Erosion control struct(Jres should be installed.
• Seedbe_ds should be well pulverl~ed, loose, and uniform.
• Fertlllzers should be appl)ed at appropriate rates.
• Seeding rates should be applied as recommended by the county agricultural extension agent.
• The seed should be applied u.niformly.
• Steep slopes should be covered with appropriate soil stabilization matting.
Blankets and Matting
Description: Blankets and matting material can be used as an aid to control erosion on critical
sites during the establishment period of protective vegetation. The most common uses are in
channels, Interceptor swales, diversion dikes, short, steep slopes; and on tldal or stream banks.
Revised April 2, 2007 ·Page l of 32
Materials:
New types of blankets and mattlng materials are continuously being developed. The Texas
Department of Transportation (TxDOT) has defined the critic al performance factors for these types
of products and has established minimum performance standards which must be met for any
product seeking to be approved for use within any of TxDOT's construction or maintenance
activities. The products that have been approved by TxDOT are also appropriate for general
construction site stabilization. . TxDOT main.tains a web site . at
http://www.dot.state.tx.us/lnsdtdotlorgchart/cmd/eroslon/contents.httm which ls updated as new
products are evaluated.
lnstallatioh:
• Install in accordance with the manufacturers recommendations.
• Proper anchoring of the material.
• Prepare a friable seed bed relatlvely free from clods and rocks and any foreign ma~erfal.
• Fertilize and seed in accordance with seeding or other type of planting plan.
• Erosion stops should extend beyond the channel liner to full design cross-section of the channel.
· • A uniform trench perpendicular to l!ne offlow may be dug with a spade or a mechanical trencher.
•Erosion stops should be deep enough to penetrate solid materlal or below level of ruling In sandy
soils.
• Erosion stop mats should be wide enough to allow turnover at bottom of trench for stapling, while
maintaining the top edge flush with channel surface.
Mulch
Description: Mulching Is the process of applying a material to the exposed soil surface to protect it
~ram erosive forces and to cons·erve soil moisture untll plants can become established. When
seeding crltlcal sites, sites with adverse soil conditions or seeding on other than optimum seeding
dates, mulch material should be applied Immediately after seedlng. Seeding during optimum
seeclng dates ~nd with favorable soils and site conditions wlll not need to be mulched.
Materials:
• Mulch may be small grain straw which shoul~ be applied uniformly.
• On slopes 15 percent or greater, a binding chemical must be applied to the surface.
•Wood-fiber or paper-fiber mulch may be applied by hydroseeding.
• Mulch nettings may be used.
•Wood chips may be used where appropriate.
Revised April 2, 2007 Page 2 of32
lnstallatlon:
Mulch anchoring should be accomplished Immediately after mulch placement. This may be done by
one of the following methods: peg and twine, mulch netting, mulch anchoring tool, or liquid mulch
binders. · · ·
Sod
Description: Sod Is appropriate for disturbed areas which require Immediate vegetative covers, or ·
where sodding Is preferred to other means of grass ·establishment. Locations particularly suited to
stabillzatlon with sod are waterways carrying intermittent flow, areas around drop inlets or in grassed
swales, and residential or commercial. lawns where quick use or aesthetics are factprs. Sod Is
composed of living plants and those plants must receive . adequate care in order to provide
vegetative stablllzatton on a disturba.d area.
Materials:
• Sod should be machine cut at a unlfol'm soil thickness.
• Pieces of sod should be cut to the supplier's standard width and length.
• Tom or uneven pads are nqt acceptable.
• Sections of sod should be strong enough to support their own wefght and retain their size and
shape when .suspended from a firm grasp.
• Sod should be harvested, delivered, and Installed wlttJln a period of 36 hours. . . .
lnstaUatlon: ·
• Areas to be· sodded should be brought to f111al grade.
• The surface should be cleared of all trash and debris.
• Fertilize according to sell tests:
• Fertilizer should be worked Into the soll.
• Sod should not be cut or laid In excessively wet or dry weather.
• Sod should not be !aid on soil surfaces that are frozen.
• During periods of high temperature, the soil should be lightly Irrigated.
• The flrst row of sod should be laid in a straight line witli subsequent rows placed parallel to and
butt ing tightly against each other.
• Lateral joints should be staggered to promote more uniform growth and strength.
•Wherever eros ion may be a problem, sod should be laid with staggered joints and secured.
Revised April 2, 2007 Page 3 of32
•Sod should be installed with the length perpendicular to the slope {on the contour). ·
. • Sod should be rolled or.tamped.
• Sod should be lnjgated to a sufficient depth.
• Watering should be performed as often as necessary to maintain soll moisture.
• The first mowing should not be attempted until the sad Is flnnly rooted.·
• Not more than one third of the grass leaf should be removed at any one cutting.
Interceptor Swale
Interceptor swales are used to shorten the length of exposed slope by Intercepting runoff, prevent
off-site runoff from entering ·the disturbed area, and prevent sedlment~laden runoff from leaving a
disturbed site. They may have av-shape or bf! trapezoidal with a flat bottom and side slopes of 3:1
or flatter. The outflow from a swale should be directed to a stabilized outlet or sediment trapping
device. The swal~s should remain In place until the disturbed area Is permanently stabilized.
Materials:
• Stabilization should consist of a layer of crushed stone three inches thick, rlprap or high velocity
erosion control mats.
• Stone stablllzatlon should be used when grades exceed 2% or v'eloclties exceed 6 feet per
second. ·
• Stabilization should extend across the bottom of the swale and up both sides of 1he channel to a
minimum height of three Inches above the design water surface elevation based on a 2-year, 24~
hour storm. ·
Installation:
• An Interceptor swale should be installed across exposed slopes during c.onstruction and should
Intercept no more than 5 acres of runoff.
•All earth removed and not needed In construction should be disposed of in an approved spoils site
so that it will not interfere with the functioning of the swale or contribute to siltation In other areas
qf the site .
• All trees , brush , stumps, obstructions and other material should be removed and disposed of so as
not to interfere with !he proper functioning of the sw.ale.
• Swales should have a maximum depth of 1.5 feet with slde slopes of 3:1 or flatter. Swales should
have positive drainage for the entire length to an outlet..
• When the slope exceeds 2 percent, or velocities exceed 6 feet per second (regardless of slope),
stabilization Is required. Stabilization should be crushed stone placed in a layer of at least 3 inches
thick or may be high velocity erosion control matting. Check dams are also recommended to

reduce velocltles in the swales possibly reducing the amount of stabilization necessary.
• Minimum compaction for the swale should be 90% standard proctor density.
Divers I on Olk es
A temporary diversion dike Is a barrier created by the placement of an earthen embankment to
reroute the flow of runoff to an erosion control device or away from an open, easily erodl.ble area. A
diversion dike Intercepts runoff from small upland areas and diverts it away from exposed slopes to
a stabilized outlet, such as a rock berm, sandbag berm, or stone outlet structure. These controls can
be used on the perimeter of the site to prevent runoff from entering the construction area. Dikes are
generally used for the duration of construction to Intercept and reroute runoff from disturbed areas to
prevent excessive erosion untll permanent drainage features are Installed and/or slopes are
stablllzed. · · ·
Materlars:·
•Stone stabillzatlon (required forvelocltles In excess of 6 fps) should consist of rlprap placed In a
layer at least 3 .lnches thick and should extend a minimum height of 3 Inches above the design
· water surface up the existing slope and the upstream face of the dike.
• Geotextlle fabric should be a non-woven polypropylene fabric deslgned-speclficallyfor use as a
soll flltratlon media wltri an approximate weight of 6 oz./yd 2, a Mullen burst rating of 140 psi, and
having an equivalent opening size (EOS) greate·r than a #50 sieve.
lnstaflatlon:
• Diversion dikes should be installed prior to and maintained for the duration of construction and
should Intercept no more than 1 ~ ~cres of runoff.
• Dikes should have a minimum top width of 2 feet and a. minimum height of compacted fill of 18
Inches measured form the top of the existing ground at the upslope toe to top of the dike and h.ave
side slopes of 3: 1 or flatter.
• The soil for the dike should be placed In lifts of 8 Inches or less and be compacted to 95 %
standard proctor-density.
• The channel, which Is formed by th~ dike, must have positive drainage for its entire length to an
outlet
• When the slope exceeds 2 percent, or velocities exceed 6 feet per second (regardless of slope},
stabllfzatlon Is required. In situations where velocities do not exceed 6 feet per second,.
vegetation may be used to control erosion.
Erosion Control Compost
Descri ption: Erosion control compost (ECC) can be used as an aid to control erosion on critical
sites during the establ ishment period of protective vegetation. The most common uses are on steep
slopes, swales, diversion dikes, and on tidal or stream banks.

Mulch Filter Berms and Socks
Description: Mulch filter berms and socks are used to Intercept and detain sediment laden run-off
from unprotected areas. When properly used, mulch fllterberms and socks can be highly effective at
controlllng sedlmentfrom disturbed areas. They cause runoff to pond which allows heavier sollds to
settle. Mulch filter banns and socks are used during the period of construction near the perimeter of
a disturbed area to Intercept sediment while allowing water to percolate through. The benn or sock
should remain In place untll the area is permanently stabilized. Mulch filter berms should not be
used when there Is a concentration of water in a channel or drainage way. If concentrated flows
occur after installation, corrective action must be taken. Mulch filter soc}<s may be installed in
construction areas and temporarily moved during the day to allow construction activity provided It ls
replaced and properly anchored at the end of the day. Mulch fllter berms and socks may be seeded

SEDIMENT CONTROL BMPS
Sand Bag Berm
Description: The purpose of a sandbag berm Is fo detain sediment.carried in runoff from disturbed
areas. This objective Is accomplished by intercepting runoff and causing It to pool behind the sand
bag berm. Sediment carried in the runoff is deposited on the upstream side of the sand bag berm
due to the reduced flow ve locity . Excess runoff volumes are allowed to flow over the top of the sand
bag berm. Sand bag berms are used only during construction activiiies in streambeds when the
contr ibuting drainage area is between 5 and 10 acres and the slope is less than 15%, i.e., utility
construction in channels , temporary channel crossing for cohstruction equipment, etc . Plastic facing
shou ld be installed on the upstream side and the berm should be ·anchored to the st reambed by
dril li ng into the rock and driving in ''T" posts or rebar (#5 or #6) spaced appropriately.

· stabillty exceeding 70 percent.
•The bag length should be 24 to 30 inches, width should be 16to18 inches and thickness should
be 6 to 8 Inches. ·
• Sandbags should be filled with coarse grade sand and free from deleterious materiai. All sand
should pass through a No. 10 sieve. The filled bag should have an approximate weight of 40
pounds. · ·
• Outlet pipe should be schedule 40 or stronger polyvinyl chloride (PVC) having a nominal Internal
diameter of 4 inches.
Installation:

at the upslope toe to the top of the berm.
•The berm should be sized as shown In the plans but should have a minimum width of 48 Inches
measured at the bottom of the berm and 16 inches measured at the top of the berm.
. .
• Runoff water should flow over the tops of the sandbags or through 4-lnch diameter PVC pipes
embedde.d below t~e top layer of bags. · · ·. · ·
• When a sandbag Is filled with materfal1 the open end of the sandbag should .be stapled or tied with
nylon or poly cord. ·
• Sandbags should ·be stacked in at least three rows abutting each other, and in staggered
arrangement.
•The base of the berm should have at least 3 sandbags. These can be reduced to 2 and 1 bag in
the second and third rows respectively.
• For each additional 6 inches of height, an additional sandbag must be added to each row width.
• A bypass pump-around system, or simllar alternative, should be used on conJunctlon with the
berm for effective dewatering of the work area.
Slit Fence
Description: A silt fence is a barrier consisting of geotextlle fabric supported by metal posts to
prevent soil and sediment loss from a site. When properly used, silt fences can be highly effective
at controlling sediment from disturbed areas. They cause runoff to pond which allows heavier solids
to settle. If not properly installed, silt fences are not likely to be effective . The purpose of a silt fence
is to intercept and detain water-borne sediment from unprotected areas of a limited extent. Silt
fence is used during the period of construction near the perimeter of a disturbed area to intercept
sediment whlle allowing water to percolate through. This fence should remain in place until the
·disturbed area is permanently stabilized. Slit fence should not be used where there ls · a
Revised April 2, 2007 Page 10 of32
concentration of water In a channel or drainage way. If concentrated flow occurs after Installation,
corrective action must be taken such as placlng a rock berm in the areas of concentrated flow. Slit
fencing within the site may be temporarily moved during the day to allow construction activity ··
provided It Is replaced and properly anchored to the ground at the end of the day. Silt fences on the
perimeter of the site or around drainage ways should not be moved at any time.
Materials:
• Slit fence material should be polypropylene, polyethylene or polyam !de woven or nonwoven fabric.
The fabric width should be 36 Inches, with a minimum unit weight of 4.5 ozlyd, mullen burst

minimum-. ·
Installation:
•Steel posts, which support the silt fence, should be Installed on a slight angle toward the
anticipated runoff source. Post must be embedded a minimum of 1 foot deep and spaced not
more than 8 feet on center. Where water concentrates, the maximum spaci~g should be 6 feet.
• Lay out fencing down~slope of disturbed area, following the contour as closely as ppsslble. The
· fence should be sited so that the maximum drainage area Is Y4 acre/100 feet of fence.
• The toe of the slit fence should be tre·nched in with a spade or mechE1nical trencher, so that the
down~slope face of the trench Is flat and perpendicular to th~ line offlow. Where fen~e cannot be
trenched In (e.g., pavement or rock outcrop), weight fabric flap wit~ 3 inches of pea gravel on
uphlll side to prevent flow from seeping under fence.
•The trench must be a minimum of6 Inches deep and 6 inches wide to allowforthe slltfencefal;>ric
to be laid In the ground and backfilled with compacted material. ·
• Silt fence should be securely fastened to each steel support post or to woven wire, which is In tum
attached to the steel fen'ce post. There should be a 3-foot overlap, securely fastened where ends

Triangular Filter Dike
Description: The purpose of a triangular sediment filter dike is to intercept and detain water-borne
sediment from unprotected areas of limited extent. The triangular sediment filter dike is used where
there is no concentration of water in a channel or other drainage way above the barrier and the
contrlbutlng drainage area is less than one acre. If the uphill slope above the dike exceeds 10%1
the length of the slope above the dike should be less than 50 feet. If concentrated flow occurs after
Installat ion, corrective action should be taken such as placing rock berm in the areas of
concentrated flow. This measure is effective on paved areas where installation of silt fence Is nc;>t
possible or where vehicle access must be maintained. The advantage of these controls is the ease

Materials:
.. .
• Slit fence material should be polypropylene, polyethylene or polyamide woven or nonwoven fabric.
The fabric width should be 36 Inches, with a minimum unit weight of 4.5 ozJyd, mullen burst
strength exceeding 190 lb/ln 2 , ultraviolet stablllty exceeding 7d%, and minimum apparent
'opening size of U.S. Sieve No. 30.
• The dike structure should be 6 gauge 6" x 6" wire mesh folded Into triangular form being eighteen
(18) Inches on each side.
Installation:
• The frame of the triangular sediment filter dike should be constructed of 6" x 6H •. 6 gauge welded
wire mesh, 18 Inches per side, and wrapped with geotextile fabric the same composition as that
used for silt fences.
• Filter material should lap over ends six (6) Inches to cover dike to dike junction; each junction
should be secured by shoat rings.
• Position dike parallel to the contours, with the end of each section closely abutting the adjacent
sections.
•There are severa!'optlons for fastening the fllterdike to the ground. The fabric skirt may be toed-In
with 6 Inches cf ~ompacted material, or 12 inches of the fabric skirt should extend uphlll and be
secured with a minimum of 3 Inches of open graded rock, .or with staples or nails. If these two ·
options are not feasible the dike structure may be trenched in 4 Inches. ·
• Triangular sediment filter .dikes should be Installed across exp~sed slopes during construction with
ends of the dike tied Into existing grades to prevent failure and should Intercept no more than one
acre of runoff. ·
•When moved to allow vehicular access, the dikes should be reinstalled as soon ~s possible, but
always at the end of the workday. ·
Rock Berm
Description: The purpose of a rock berm Is to serve as a check dam in areas of concentrated flow,
to Intercept sediment-laden runoff, detain the sediment and release the water in sheet flow. The
rock berm should be used when the contributing drainage area Is less than 5 acres. Rock berms
are used In areas where the volume of runoff Is too great for a silt fence to contain. They are less
effective for sediment removal than silt fences, particularly for fine particles, but are able to
withstand higher flows than a silt fence. As such , rock berms are often used.in areas of channel
flows (ditches, gullies, etc.). Rock berms are most effective at reducing bed load in channels and
should not be substituted for other erosion and sediment control measures further up the watershed.
Materials :
• The berm structure should be secured with a woven wire sheathing having maximum opening of 1
Inch and a minimum wire diameter of 20 gauge galvanized and should be secured with shoat ·
rings.
Revised April 2, 2007 Page 12of32
•Clean, open graded 3;. to 5-inch diameter rock should be used, except In areas when~ high
·velocities or large volumes of flow are expected, where~ to 8~1nch diameter rocks may be used.
· · lnstallatlon:
. .
• Lay out the woven wire sheathing perpendicular to the flow llne. The sheathing should be 20
gauge woven wire mesh with 1 Inch openings.
•Benn should have a top width of 2 feet minimum with side slopes being 2:1 (H:V) or flatter.·.
• Place tne rock along the sheathing to a height not less than 1811
•
• Wrap the wire sheathing around the rock and secure with tie wire so that the ends of the
sheathing overlap at least 2 Inches, and the berm retains Its shape when walked upon.
• Berm shoulel be built along the contour at zero percent grade or as near as posslble.
• The ends of the berm should be tied Into existing upslope grade and the berm should be buried In
a trench approximately 3 to 4 Inches deep to prevent failure of the. control. ·
Hay Bale Dike · ·
Description: The purpose of a hay or straw bale dike Is to Intercept and detain small amounts of
sedlment-la!=lan runoff from relatively small unprotected areas. Straw bales are to be used when it Is
not feasible to install other, more effective measures or when the construction phase Is expected to
last less than 3 months. Straw bales should not be used on areas where rock or other hard
surfaces prevent the full and uniform anchoring of the bar!ler.
Materials:
Straw: The best quality straw mulch comes from wheat, oats or barley and should be free of weed
and grass seed which may not be desired vegetation for the area to be protected. Straw mulch Is
llght and therefore must be properly anchored to the ground.
Hay: This is very similar .to straw with the exception that It Is made of grasses and weeds and not
grain stems. This form of mulch Is very Inexpensive and Is widely available but does introduce weed
and grass seed to the area. Like straw, hay Is light and must be anchored. .
• Straw bales should weigh a minimum of 50 pounds and should be at least 30 Inches long.
· • Bales should .be composed entirely of vegetable matter and be free of seeds.
· • Binding should be either wire or nylon string, jute or cotton binding is unacceptable. Bales should
be used for not mor~ than two months before being replaced.
Installation:
" Bales should be embedded a minimum of 4 inches and securely anchored using 2" x 2JJ wood
· stakes or 3/8" diameter rebar driven through the bales into the ground a minimum of 6 inches.
• Bales are to be placed directly adjacent to one another leaving no gap between them .
R~v i sed April 2, 2007 Page 13of32

Brush Berms
Organic litter and spoil material from site clearing operations Is usually bu med or hauled away to be
dumped elsewhere. Much of this material can be used effectively on the construction site Itself. The
key to constructing an efficient brush berm is In the method used to obtain and place the brush. It
will not be acceptabl~ to simply take a bulldozer and push whole trees into a pile. This method does
not assure continuous ground contact with the berm and will allow uncontrolled flows under the
berm. .
Brush berms may be used where there Is little or no concentration of water In a channel or other
drainage way above the benn. The size of the drainage area should be no greater than one-fourth of
an acre per 100 feat of barrier. length; the maximum slope length behind the barrier should not
exceed 100 feet; and the maximum slope gradient behind the barrier should be less than 50 percent
(2:1). . .
Materials:
• The brush should consist of woody brush and branches, preferably less than 2 inches In diameter . . · .
• The filter fabric should conform to the speclflcatlons for filter fence fabric.
• The rope should .be V4 inch po.lypropylene or nylon rope.
• The anchors should be 3/8-inch diameter rebar stakes that are 18-inches long.
Installation:
• Lay out the brush benn following the contour as closely as possible.
• The juniper lim.bs should be cut and hand placed with the vegetated part of the limb in close
contact with the ground. Each subsequent branch should overlap the previous branch providing a ·
shingle effect.
•The brush berm should be constructed in lifts with each layer extending the entire length of the
berm before the next layer is started.
• A trench should be excavated 6-inches wide and 4-lnches deep along the length .of the barrier and
Immediately uphlll from the barrier.
• The filter fabric should be cut into lengths sufficient to lay across the barrier from its up-slope base
to just beyond Its peak. The lengths of filter fabric should be draped across the width of the barrier
with the uphill edge placed in the trench and the edges of adjacent pieces overlapping each other.
Where joints are necessary, the fabric should be spliced together with a minimum 6-inch overlap
Revi1ed April 2, 2007 Page 14of32
and ~ecurely sealed.
• The trench should be backfilled and the soil compacted ·over the filter fabric.
• Set stakes into the ground along the downhlll edge of the brush barrier, and anchor the fabric by
tying rope from the fabric to the stakes. Drive the rope anchors Into the ground at approximately a
45--degree angle to the ground on 6-foot centers.
• Fasten the rope to the anchors and tighten benn securely to the ground with a minimum tension
of 50 pounds. ·
• . The height of the brush benn should be a minimum of 24 inches after the securing ropes have
been tight~ned.
Stone Outlet Sediment Traps
A stone outlet sedlment trap is an lmpoundment created by. the placement of an earthen and stone
emb~nkment to prevent soil and sediment loss from a site. The purpose of a sediment trap ls to
Intercept sediment-laden runoff and trap the sediment In order to protect drainage ways; properties
and rights of way below the sediment trap from sedimentation. A sediment trap Is usually Installed at
points of dlscha·rge from disturbed areas. The drainage area for a sediment trap Is recommended to
be less than 5 acres.
Larger areas should be treated using a sediment basin. A sediment trap differs from a
sediment basin mainly in the type of discharge structure. The trap should be located to obtain the
maximum· storage benefit from the terrain, for ease of clean out and disposal of the trapped ·
sediment and to minimize Interference with construction activities. The volume of the trap should be
at least 3600 cubic feet per acre of drainage area.
Materials:
• All aggregate should be ,at lest 3 inches in diameter and should not exceed a volume of 0.5
cubic foot.
• The geotextlle fabric specification should be woven polypropylene, polyethylene or polyamide
geotextlle, minimum unit weight of :4.5 ozlyd 2, mullen burst strength at least 250 lb/in 2,
ultraviolet stability exceeding 70%, and equivalent opening size exceeding 40.
Installation:
• Earth Embankment Place fill material in layers not more than 8 inches In loose depth. Before
compaction, moisten or aerate each layer as necessary to provide the optimum moisture content
of the material. Compact each layer to 95 percent standard proctor density. Do not place
material on surfaces that are muddy or frozen. Side slopes for the embankment are to be 3:1.
The minimum width of the embankment should be 3 feet.
• A gap is to be left In the embankment in the location where the natural confluence of runoff
crosses the embankment line. The gap Is to have a width in feet equal to 6 times the drainage
area in acres.
Revi sed April 2, 2007 Page 15of32
• Geotextile Covered Rock Core: A core of filter stone having a minimum height of 1.5 feet and a
minimum width at the base of 3 feet should be placed across the opening of the· earth
embankment and should be covered_by geotextlle fabric which should extend a minimum
distance of 2 feet In either direction from the base of the fllter stone core.
• Filter Stone Embankment: Filter stone should be placed over the geotextile and is to have a side .
slope wtiich matches that of the earth embankment of 3: 1 and should cover the geotextile/rock
core a minimum of 6 inches when Installation is complete. The crest of the outlet should be at
least 1 foot below the top of the embankment.
Sediment Basins:
The purpose of a sediment basin is to intercept sediment-laden run<?ff and trap the sediment in order
to protect.drainage ways, properties and rights of way below the sediment basin from sedimentation.
A sediment basin is usual_ly Installed at points of discharge from disturbed areas. The drainage area
for a sediment basin Is recommended to be less than 100 acre~.
Sediment basins are effective for capturing and slowly releasing the runoff from larger disturbed
areas thereby allowlng sedimentation to take place. A sediment basin can be created where a
permanent pond BMP ls being constructed. Guidetlnes for construction of the permanent BMP
should be followed, but revegetatlon, placement of underdrain piping, and installatlon of sand or
other filter media should not be carried out until the site construction phase Is complete.
Materials:
• Riser should be corrugated metal or reinforced concrete pipe or box and should have watertight
fittings or end to end connections of sections.
• _An outlet pipe of corrugated metal or reinforced con9rete should be attached to the riser and
should have positive flow to a stabilized outlet on the downstream side of the embankment.
• An anti-vortex device and rubbish screen should be attached.to the top of the riser and should
be made of polyvinyl chloride or corrugated metal.
Basin Design and Construction:
• For common drainage locations that serve an area with ten or more acres disturbed at one time,
• a sediment basin should provide storage for a volume of rµnoff from a two-year, 24-hour storm
from each disturbed acre drained.
• The basin length to width ratio should be at least 2:1 to improve trapping efficiency. The shape
may be attained by excavation or the use of baffles. The lengths should be measured at the
elevatlon of the riser de-watering hole.
• Place .fl!! material in layers not more than 8 i~ches in loose depth. Before compaction, moisten or
aerate each layer as necessary to provide the optimum moisture content of the material.
Compact each layer to 95 percent standard proctor density. Do not place material on surfaces
that are muddy or frozen. Side slopes for the embankment should be 3:1 (H:V).
• An emergency spillway should be installed adjacent ~o the embankment on undisturbed son and

of freeboard fess the amount which can be carried by the principal outlet contra! device.
• The emergency spillway should be lined with rlprap as should the swale leading from the
spillway to the normal watercourse at the base of the embankment.
• The principal outlet control device should consist of a rigid vertically oriented pipe or box of
corrugated metal-or reinforced concrete . Attached to·this structure should be a horizontal pipe,
which should extend through the embankment to the toe of fill to provide a de-watering outlet for
the basin .
• An anti-vortex device .should be attached to the inlet portion of the principal outlet control device
to serve as a rubbish screen.
• A concrete base should be used to anchor the principal outlet control device and should be
sized to provide a safety factor of 1.5 (downward forces= 1.~ buoyant forces).
• The basin should Include a permanent stake to Indicate the sediment level in .the pool and
marked to Indicate when the sediment occupies 50% of the basin volume (not the top of the
stake). ·
• The top ofthe riser pipe should remain open and be guarded with a trash rack and antl·vortex
device. The top of the riser should be 12 lnche~ below the elevation of the emergency splllway.
The riser should be sized to convey the runoff from the 2-year, 3-hot.ir storm when the water
surface Is at the emergency spillway elevation . For basins with no spillway the riser must be
sized to convey the runoff from the 10-yr, 3-hour storm.
• Anti-seep · collars should be Included when soil conditions or length of service make piping ·
through the backfill a posslbility.
. • The 48-hour drawdown time will b·e achieved by using a riser pipe peiforated at the point
measured from the bottom of the riser pipe equal to 112 the volume of the basin. This ls the
maximum sediment storage elevation. The size of the perforation may be calculated as follows:
Where :
Ao= Asx~
Cdx980,000
A0 = Area of the de-watering hole, ft 2
A,= Surface area of the basin, ft 2
Cd= Coefficient of contraction, approximately 0.8
h = head of water above the hole, ft .
Perforating the riser with multiple holes with a comb ined surface area
equal to A 0 is acceptable.

POST-CONSTRUCTION TSS CONTROLS
Retention/Irrigation Systems
Description: Retention/irrigation systems referto the capture of runoff in a holdlng pond, then use
of the captured water for irrigation of appropriate landscape areas. Retention/irrigation systems are
characterized by the capture and disposal of runoff without direct release of captured flow to
receiv ing streams. Retention systems exhibit excellent pollutant removal but can require regular,
proper maintenance. Collection of roof runoff for subsequent use (rainwater harvesting) also
qua li fies as . a retention/Irrigation practice, but should be operated and sized to provide adequate
volume. This technology, which emphasizes beneficial use of stormwater runoff. Is particularly
appropriate fqr ar1d regions because of increasing demands on water supplies for agricultural
irrigat ion and urban water supply.

Design Consldera~lons: Retention/Irrigation practices achieve 100% removal efficiency of total
suspended solids contained within the volume of water captured. Design elements of
retention/irrigation systems Include runoff storage facility configura~ion and sizing, pump and wet
well system components, basin lining; basin detention time, and physical and operational
components of the Irrigation system: Retention/Irrigation systems are appropriate for large drainage
areas with low to moderate slopes. The retention capacity should be sufficient considering the
average rainfall eva.nt for the area. ·
Maintenance Requirements: Maintenance requirements for retention/irrigation systems include .
routine inspections, sediment removal, mowing, debris and litter removal, erosion control, and
nuisance control.
Extended Detention Basin
Description: Extended detention facilities are basins that temporarily store a portion of stonTiwater
runoff following a storm event. Extended detention basins are normally used to remove partlculate
pollutants and to reduce maximum runoff rates associated with development to their pre-
development levels. The water quality benefits are the removal of sediment and buoyant materials.
Furthennore, nutrients, heavy metals, toxic materials, and oxygen-demanding materials associated
with the particles also are removed. The control of the maximum runoff rates serves to protect
drainage channels below the device from erosion and to reduce doVi'.nstream flooding. Although
detention facilities designed for flood control have different design requirements than those used for
.water quality enhancement, It Is possible to achieve these two objectives In a single faclllty.
Design Considerations: Extended detention basins can .remove approximately 75% of 1he total
suspended solids contained within the volume of runoff captured in the basin .. Design elements of
extended detention basins Include basin sizing, basin conflguratlon, basin side slopes, basin lining,
Inlet/outlet structures, and erosion controls. Extended detention basins are .appropriate for large
drainage areas with low to moderate slopes. The retention capacity should be sufficient considering
the average rainfall event for the area.
Maintenance Requirements: Maintenance requirements for extended detention basins Include
routine Inspections, mowing, debris and litter removal, erosion control, structural repairs,·nulsance
control, and sediment removal.
Vegetative Filter Strips
Description: Filter strips, also known as vegetated buffer strips, are vegetated sections of land
similar to grassy swales except they are essentially flat with low slopes, and are designed only to
accept runoff as overland sheet flow. They may appear in any vegetated ·form from grassland to
forest, and are designed to Intercept upstream flow, lower flow velocity, and spread water out as
sheet flow. The dense vegetatlva cover facilitates conven'tional pollutant removal through detention,
filtration by vegetation, and Infiltration.
Filter strips cannot treat high velocity flows, and do not provide enough storage or infiltration to
effectively reduce peak discharges to predevelopment levels for design storms. This lack' of quantity
control favors use In rural or low-density development; however, they can provide water quality
benefits even where the impervious cover Is as high as 50%. The primary highway application for
vegetative filter strips Is along rural roadways where runoff that would otherwise discharge directly to
Rev ised April 2, 2007 Page 22 of32
a receiving water passes through the filter strip before entering a conveyance system. Properly
designed roadway medians and shoulders make effective buffer strips. These devices also can be
used on other types of development where land is available and hydraulic conditions are
appropriate.
Flat slopes and low to fair permeability of natural subsoil are required for effective performance of
fllter strips. Although an inexpensive control measure, they are most useful In contributing watershed
areas where peals runoff velocltles are low as they are unable to treat the high flow velocities.
typlcally associated wit~ high Impervious cover.
Successful performance of filter strips relies heavily or\ maintaining shallowunconcentratedflow. To
avoid flow channelization and maiAtaln perfonnance, a filter strip should:
• Be equipped with a level spreading device for even distribution of runoff
• Contain dense vegetation with a mix of erosion resistant; soil binding species
• Be graded to a uniform, even and relatively low slope
• Laterally traverse the contributing runoff area
Fiiter strips can be used upgradient from watercourses, wetlands, or other water bodies along toes
and tops of slopes and at outlets of other stormwater management structures. They should be
Incorporated Into street drainage and master drainage planning. The most important criteria for
·selection and use of this BMP are soils, space, and ·slope.
Design Considerations: Vegetative filter strips can remove approximately 85% of the total
suspended solids contained within the volume of runoff captured. Design elements of vegetative
filter strips include unlform,·shallow overland flow across th.a· entire filter strip area, hydraulic load Ing
rate, inlet structures, slope, and vegetative cover. The area should be free of gu111es or rills which
can concentrate flow. Vegetative filter strips are appropriate for small drainage areas with moderate .
slopes. Other desl~.n elements include the following: ·
• Solis and moisture are ad~quata to gro~ relatively dense vegetative stands
• Sufficient space is available
• Slope is less than 12%
• Comparable performance to more expensive structural controls
Maintenance Requirements: Maintenance requltements for vegetative filter strips Include pest
management, seasonal mowing and lawn care, routine Inspections, debris and litter removal,
sediment removal, and grass reseeding and mulching .
Constructed Wetlands
Description: Constructed wetlands provide physical, chemical, and biological water quallty

treatment of stormwater runoff. Physical treatment occurs as a result of decreasing flow velocities In
the wetland, and is present in the form of evaporation, sedimentation, adsorption, and/or filtration.
Chemical processes include chelation, precipitation,' and chemical adsorption. Biological processes
include decomposition, plant uptake and removal of nutrients, plus biological transformation and
degradation. Hydrology Is one of the most Influential factors in poilutant removal due to Its . effects
on sedimentation, aeration, biological transformation, and adsorption onto bottom sediments.
The wetland should be designed such that a mlnimum ·amount of maintenance is required. The
natural surroundings, Including such things as the potential energy of a stream or flooding river,
should be utilized as much as possible. The wetland should approximate a natural situation and
unnatural attributes, such as rectangular shape or rigid channel, should ~e avoided.
Site considerations should include the water table depth, sell/substrate, and space requirements.
Because the wetland must have a source offlow, it Is desirable that the water table Is at or near the
surface. If runoff is the only source of Inflow for the wetland, the water level often fluctuates and
establishment of vegetation may be difficult The soil or substrate of an artlflcial wetlan.d should be
loose loam to clay. A perennial baseflow must be present to sustain the artlflcla! wetland. The
presence of organic material Is often helpful In Increasing pollutant r,emoval and retention. A greater
amount of space Is required for a wetland system than Is required for a detention facility, treating the
same amount of area.
DesJgn Considerations.: Constructed wetlands can remove over90% of the total suspended solids
. contained within the volume of runoff captured In the weUand. Design elements of constructed
wetlands Include wetland sizing, wetland 'configuration, sediment forebay, vegetation, outflow
structure, depth of inundatlon during storm events, depth of mlcropools, and aeration. Constructed
wetlands are appropriate for large drainage areas with low to moderate slopes. ·
Maintenance Requirements: Maintenance requirements for constructed wetlands include mowing,
routine Inspections, debris and litter removal, erosion control, nuisance control, structural repairs,
sediment removal, harvesting, and maintenance of water levels.
Wet Basins
Description: Wet basins are runoff control facilities that maintain a permanent wet pool and a
standing crop of emergent littoral vegetation. These facilities may vary In appearance from natural
ponds to enlarged, bar.med (manmade) sections of drainage systems and may function as onllne or
offline facll!tles, although offllne configuration Is preferable. Offllne designs can prevent scour and
other damage to the wet pond and minimize costly outflow structure elements needed to
accommodate extreme runoff events .
During storm events, runoff inflows displace part or all of the existing basin volume and are retained
and treated in the facility until the next storm event. The pollutant removal mechanisms are settling
of so!lds, wetland plant uptake, and microbial degradation. When the wet basin is adequately sized,
pollutant removal performance can be excellent, especially for the dissolved. fraction. Wet basins
also help provide erosion protection for the receiving channel by limiting peak flows during larger
storm events. Wet bas ins are often perceived as a positive aesthetic element in a community and
offer significant opportunity for creative pond configuration and landscape design. Participation of
an experienced wetland designer is suggested. A significant potential drawback for wet ponds in
a~id climates is that the contributing watersh~d for these facilities is often incapable of providing an
adequate water supply to maintain the permanent pool, especially during the summer months.
Makeup water (i.e., well water or municipal drinking water) is sometimes used to supplement the

I·
ralnfall/runoff process, especially for wet basin facilities treatlng watersheds that generate
Insufficient runoff.
Design Considerations: Wet basins can remove over 90% of the total suspended solids contained
within tha volume of runoff captured In the basin. Design elements of wet basins include basin
sizing, basin configuration, basin side slopes, sediment forebay, inflow and outflow structures,
vegetation, depth of permanent pool, aeration, and erosion control. Wet basins are appropriate for
large drainage are1:1s with low to moderate slopes.
Maintenance Requirements: Maintenance requirements for wet basins include mowing, routine
inspections, debris and litter removal, erosion control, nuisance control, structural repairs, sediment
removal, and harvesting.
Grassy Swales
Grassy swales are vegetated channels that convey stonnwater and remove pollutants by flltratlon
through grass and 'infiltration through soll. They require shallow slopes and soils that drain well.
Pollutant removal capability is related to channel dimensions, longltudinal slope, and type of
vegetation. Optimum design of these components wlll ino~ease contact time of runoff through the
swale and Improve pollutant removal ·rates.
Grassy swales. are prlmarlly stormwater conveyance systems. They can provide sufficient control
under light to moderate runoff conditions, but their ability to control large storms Is limited. Thar.afore,
they are most applicable in low to moderate sloped areas qr along highway medians as an
alternative to ditches and curb and gutter drainage .. Their performance diminishes· sharply In highly
urbanized settings, and they are generally not effective enough to receive construction stage runoff
where high sediment load.s can ovaiwhelm the system. Grassy swales can be used as a
pretreatment measure for other downstream BMPs,.such as extended detention basins. Enhanced
grassy swales utlllze check dams and wide depressions to Increase runoff storage and promote
gre.ater settling of pollutants.
Grassy swales can be more aesthetically pleasing than concrete or rock-lined drainage systems and
ar& generally Jess expensive to construct and maintain. Swales can slfghtly reduce impeJVious area
and red'uce the pollutant accumulatlon and dellvery associate_d with curbs and gutters. The
disadvantages of this technique include the possibility of erosion and channelization over time, and
the need for more right-of-way as compared to a storm drain system. When properly constructed,
inspected, and maintained, the llfe
expectancy of a swale is estimated to be 20 years.
Design Con'slderatlons:
• Comparable performance to wet basins
· • Limited to treating a few acres
• Avallablllty of water during dry periods to maintain vegetation
• Sufficient available land area
The suitability of a swale at a site will depend on land use, size of .the area serviced, soil type , slope,
imperviousness of the contributing ~atershed, and dimensions and slope of the swale system. In

general, swales can be used to serve areas of less than 1 O acres, with slopes no greater than 5 %.
The seasonal high water table should be at least 4 feet below the surface. Use of natural
topographic lows is encouraged, and natural drainage courses should be regarded as significant
local resources to be kept In use. · ·
Maintenance Requirements:
Research in the Austin area indicates that vegetated controls are effective at removing pollutants
even when donnant. Therefore, irrigation Is not required to maintain growth during dry periods, but
may be necessary only to prevent the vegetation from dying. . ·
Vegetation Lined Drainage Ditches
Vegetation lined drainage ditches are simllar to grassy swales. These drainage ditches are
vegetated channels that convey storm water and remove pollutants by filtration through grass and
inflltratlon through soil. They require solls that drain well. Pollutant removal capablllty is related to
channel dimensions, longitudinal slope, and type of vegetation. Optimum design of these
components wlll lncrease contact time of runoff through the ditch and Improve pollutant removal
rates. Vegetation lined drainage ditches are primarily storm water conveyance systems. They have
vegetation lined In the low flow channel and may Include vegetated shelves.
Vegetation In drainage ditches reduces.erosion and removes pollutants by lowering water velocity
over the soil surface, binding soil particles with roots, and by filtration through grass and Infiltration
through soil. Vegetation lined drainage ditches can be used w~ere:
• A vegetative llnlng can provide sufficient stablllty for .the channel grade by Increasing maximum
permissible velocity
• Slopes are generally less than 5%, with protection from sheer stress as needed through the use of
BMPs, such as erosion control blankets
• Site conditions required to establish vegetation, I.e. cnmata, soils, topography, are present
Design Criteria: The sultablllty of a vegetation lined drainage ditch at a site will depend on land
use, size of the area serviced, sol! type, slope, imperviousness of the contributing watershed, and
dimensions and slope of the ditch system. The hydraulic capacity of the drainage ditch and other
elements such as erosion, siltation, and pollutant removal capability,. must be taken into
consideratl9n. Use of natural topographic lows Is encouraged, and natural drainage courses should
be regarded as significant local resources to be kept In use. Other items to consider Include the
following:
• Capacity, cross-section shape, side slopes, and grade
.. .Select appropriate native vegetation
• Construct in stable, low areas to conform with the natural drainage system. To reduce erosion
potential, design _the channel to avoid sharp bends and steep grades.
• Design and build drainage ditches with appropriate scour and eros ion protection. Surface
· water should be able to enter over the vegetated banks without eros ion occurring.
Rc vi sfd April 2, 2007 Page 26of32
• BMPs, such as erosion control blankets, may need to be installed at the time of seeding to
provide stablllty until the vegetation is fully established. It may also· be necessary to divert water
from the channel untll vegetation Is established or to line the channel with sod.
. .
• Vegetated ditches must not be subject to sedimentation from disturbed areas.
• Sediment traps may be needed at channel inlets to prevent entry of muddy runoff and channel
sedimentation.
• Avallabtllty of water during dry periods to maintain vegetation
• Sufficient avallable land area
·Maintenance:
During establishment, vegetation lined drainage ditches should be Inspected, repaired, and
vegetation reestablished if necessary. After the vegetation has become established, the ditch
should be checked perlodlcally to determine if the channel is withstanding flow velocities without
damage. Check the ditch for debris, scour, or erosion and Immediately make repairs If needed.
Check the channel outlet and all road crossings for bank stablllty and evidence of piping or scour
holes and make repairs Immediately. Remove all significant sediment accumulatlons to maintain
the designed carrying capacity. Keep ·the vegetation In a healthy condition at all times, sln~e It Is
the primary erosion protection for the channel. Vegetation lined drainage ditches should be
seasonally maintained by mowing or irrigating. depending on the vegetation selected. The long-
term management of ditches as stable, v~getated, "natural" drainage systems with native
vegetation buffers Is highly recommended due to the Inherent stability offered by grasses,
shrubs, trees, and other vegetation.
Research in the Austin area indicates that vegetated controls are effective at removing pollutants
even when dormant. Therefore, irrigation ls not required to maintain growth during dry periods, but
. may be necessary only to prevent-the vegetation from dying. ·
Sand Filter Systems
. .
The objective of sand filters is to remove sediment and the pollutants from the first flush of
pavement a.nd impervl:.us area runoff. The filtratlon of nubients, organics, and coliform bacteria Is
enhanced by a mat of bacterial sl!me that develops during normal operations. One of the main
advantages of sand filters ls their adaptability; they can be used on areas with thin soils, high
evaporation rates, low-so!I inflltratlon rates, in llmlted-space areas, and where groundwater Is to be

Since their original inception in AustJn, Texas, hundreds of intermittent sand filters have been
implemented to treat stormwater runoff. There have been numerous alterations or variations ln the
orig inal design as engineers in other jurisdictions have improved and adapted the technology to
meet their specific requirements. Major types include the Austin Sand Filter, the District of Columbia
Underground Sand Filter, the Alexandria Dry Vault Sand Filter, the Delaware Sand Filter, and peat-
s.and filters which are adapted to provide a sorption layer and vegetative cover to various sand filter
designs.

. Design Considerations:
• Appropriate for space-Hmlted areas
• Appllcable In arid climates where wet basins and constructed wetlands are not appropriate
• High TSS removal efficiency
Cost Considerations:
Filtration Systems may require less land than some other BMPs, reducing the land acquisition
cost; however the structure Itself Is one of the more expensive BMPs. In addition, maintenance
cost can be substantial. ·
Erosion Control Compost
Description: Erosion control compost (ECC) can be used as an aid to control erosion on crltlcal
sites during the establishment period of protective vegetation. The most common u~es are on steep
slopes, swales, diversion dikes, and on t!dal or stream banks . ·
Materlals:
New types of erosion control compost are continuously being developed. The Texas Department of
Transportation (TxDOT) has established minimum performance standards whlph must be met for
any products seeking to be approved for use within any of TxDOT's construction or maintenance
activities. Material used within any TxDOT construction or maintenance activities must meet .
material specl~catlons In accordance with current TxDOT specifications. TxDOT maintains a
website at http:l/www.dot.state.tx.us/des/landscape/compost/specitlcations.htm that provides
information on compost specification data. This website also contains lnfonnatlon on areas where
the Texas Commission on Envlronmental Quality (TCEQ) restricts the use of certain compost
products.
ECC' used for projects not related to TxDOT should also be of quality materials by meeting
performance standards and compost speplflcation data. To ensure the quality of compost used as
an ECC, products should meet all applicable state and federal regulations, Including but not limited
to the United States · Environmental Protection Agency (USEPA) Cade of Federal Regulations
(CFR), Title 40, Part 503 Standards for Class A blosollds and Texas Natural Resource Conservation
Commission (now. named TCEQ) Health and Safety Regulations as · defined In the Texas
Adrfllnistratlon Code (TAC), Chapter 33~, and all other relevant requirements for compost products
out li ned In TAC, Chapter 332. Testing requirements required by the TCEQ are defined in TAC
Chapter 332, includ ing Sections §332.71 Sampling and Analysis Requirements for Final Prod4cts
and §332.72 Final Product Grades. Compost specification data approved by TxDOT are
appropriate to use for ensuring the use of quality compost materials or for guidance.
Testing standards are dependent upon the Intended use for the compost and ensures product
safety, and product performance regarding the product's specific use. The app ropriate compost

Mulch Filter Berms and Socks
Description: Mulch filter berms and socks are used to Intercept and detain sediment laden run-off
from unprotected areas. When properly used, mulch filter berms and socks can be highly effective at
controlllng sediment from disturbed areas. They cause runoff to pond which allows heavier solids to
settle. Mulch filter berms and socks are used during the period of construction near the perimeter of
a disturbed area to Intercept sediment while allowing water to percolate through. The berm or sock
should remain In place until the area is permanently stablllzed. Mulch filter berms should not be
used when there Is a concentration of water in a channel or drainage way. If concentrated flows
occur after lnstallatlon, corrective action must be taken. Mulch filter socks may be Installed In
construction areas and temporarily moved during the day to allow construction activity provided it is
replaced and properly anchored at the end of th~ day. Mulch filter berms and socks may be seeded
to allow for quick vegetative growth and reduction In run-off velocity.

Sedimentation Chambers (only to be used when there Is no space available for other
approved BMP's) ·
Description: Sedimentation chambers are stormwater treatment structures that can be used
when space Is limited such as urban settlngs. These structures are often tied Into stormwater
drainage systems for treatment of stormwater prior to entering state waters. The water qualfty
benefits are the removal of sediment and buoyant materials. These structures are not designed
as a catch basin or detentipn basin and not typically used for floodwater attenuation.
Design Considerations: Average rainfall and surface area should be considered when
followlng manufacturer's recommendations for chamber sizing and/or number of units needed to
achieve effective TSS removal. If properly sized, 50~80% removal of TSS can be expected.
Maintenance Requirements: Maintenance requirements include routine Inspections, sediment,
debris and litter removaf, erosion control and nuisance control.

After further review of this Preliminary Plat the proposed driveway located approximately
570 ' east of Holleman Drive extension will not be all<;>wed access due to its proximity to the
proposed eastbound Loop Ramp @ the FM 2818 Overpas·s Bridge @ UPRR /FM 2154 . An
internal parallel roadway or access to an adjacent roadway will be required. Also, the 4. 36 acre
Oil Well I Utility Substation Site will be required to access this subdivision internally. Further,
the proposed extension of Holliman Drive may require additional environmental
clearance . Further information will be provided on this issue . Initial Tudor Project Schematic
was approved 2005. Please call 778-6233 if you have any questions.
R nse: We are working on TxDOT permits but they will not be ready until late March.
addition to the following standard comments , if more than 5 acres will be disturbed during
construction of this project a NOi must be filed with the state and a copy provided to the CoCS .
Storm water management requirements are as follows , any questions may be d i rected to

Re: COTTAGES AT COLLEGE STATION FINAL PLAT INFRASTRUCTURE PLANS
Dear Jason:
The purpose of this letter is to acknowledge that the construction plans for the water
and drainage for the above-referenced project , to the best of my knowledge , do not
deviate from the B/CS Design Guideline Manual.
The streets are designed with on street park ing per the approved Concept Plan . Rather
than us ing a standard 38 ' street cross section per the B/CS Design Guidelines which
allows 2 -8' parallel parking stalls and 2 -11 ' lanes we widened the cross section to
allow for large bus and fire truck turning rad i i. Our cross section is now 47' back to back
of curb allowing for 2-13 ' lanes and 2 -10 .5' parallel parking lanes. This wider cross
section will allow for more maneuverability of vehicles through the area . We intend to
stripe th e parallel parking stalls and I cannot find a prohibition of this st riping in the B/CS
Design Guidelines so I have assumed it is allowed . In addition we have provided w ider
pedest ri an areas "bump outs " at the intersections to create a more pedestrian friendly
e nvironment (i .e . the pedestrian crossing a 26 ' street as opposed to a 47' street) and to
protect t he end of the last parallel parking stall. We are also carrying the drainage flow
along a crease in the roadway at the common line between the 10.5 ' parking stall and
the 13 ' travel lane . This will allow us to carry the water around the "bump outs " more
effectively rather than carry a flume through the "bump out".
In addit ion the h ike/ bike trail shown has been brought to the back of curb when
crossing the dra inage structures .
I also acknowledge , to the best of my knowledge , that the details provided in the
nstruction plans are in accordance with the Bryan/College Station Standard Details.

ENGINEERING COMMENTS NO. 2
1. TxDOT Comments :
Cottages of College Station (Prelim . Plat) (FM 2818) -Access driveways to FM 2818 must
meet TxDOT's current "Regulations for Access Driveways to State Highways ".
Regulations are primarily based on posted speed limits and distances between
proposed & adjacent access points. Where the posted speed limit is 50 MPH or greater the
required spacing between access points is 425 '; @ 45 MPH the required spacing is 360 '.
Where access spacing is insufficient joint access will be required or access to
internal/external streets. Appropriate data , including drainage will be required for any future
work/permits in the ROW@ this development site .
Cottages of CS (Preliminary Plat) (FM 2818) -See Previous Comments. (January 14,
2008) Due to the complexity of the ongoing TxDOT Projects @ this location (FM
2154 Widening & FM 2818 Overpass@ UPRR /FM 2154) there will additional
comments furnished regarding this Preliminary Plat by January 23. 2009 . Please
call 778-6233 if you have any questions.
The proposed street connection to FM 2818 located between Lot 1, Block 2 and Lot 1,
Block 4 does not comply with TxDOT's current plans for the FM 2818 I 2154 grade
separation . Please address this issue with TxDOT.
To date what has been discussed and/or resolved with TxDOT?
2 . Based on the proposed phasing plan and the proposed 12 inch water main illustrated along
Dowling Road , the water system proposed for Lot 2 , Block 1 and Lot 1, Block 5 does not
meet the looping requirement in the BCS Design Guidelines, please revise . This may be
accomplished by illustrating the water mains needed to loop these dead end portions of
main back to the system , with the understanding that upon site development these
alignments may vary. 1..re.(I C'5 5.. cw~ -h, L.r I 1/._f< j'
3 . The radii proposed along the street separating Phase 1 and 3 , needs to meet the minimum
standards in the BCS Guidelines, please revise . fa~ 1._.\.. c..•L fl,...,( 1 ~J 1 ,·

Re: COTTAGES OF CS (PP)-PRELIMINARY PLAT (08-00500333)
Dear Jason ,
We would like to request a variance to the two following requirements :
1. Provide PUEs at the rear of all lots.
January 16 , 2009
Because this plat is for multi-family and commercial properties this Subdivision
Ordinance requirement is not applicable. Easements for utilities on multi-family and
commercial properties are not usually contained at the rear of the lots . Often these
utilities run through the property and are contained in easements under parking or in
green space areas . This ordinance requirement was really written for single family
residential properties where utilities are run along the rear property lines to be shared by
both tiers of lots and therefore is not extremely applicable to non single family
residential properties . We will be providing sufficient easements for all utilities for these
properties .
Provide sanitary sewer service to al/ lots.
e only lot which will not have access to sanitary sewer service is Lot 2, Block 4 which
is t lot currently being developed by the City as an electrical substation . The City of
College Station has been planning for this area to contain an electrical substation for
some time now . Their design plans never called for provision of sanitary sewer facilities
to this property .
Thanks for your assistance in processing these variance requests . Please do not
sitate to call if you have any questions .

TEXAS TITLE INSURANCE INFORMATION
Title insurance insures you against loss resulting from certain
risks to your title.
The Commitment for Title Insurance is the title insurance
company's promise to issue the title insurance policy. The
Commitment is a legal docwnent. You should review it
carefully to completely understand it before your closing date.
El seguro de titulo le asegura en relacion a perdidas resultantes
de ciertos riesgos que pueden afectar el titulo de su propiedad.
El Compromiso para Seguro de Titulo es la promesa de la
compania aseguradora de titulos de emitir la poliza de seguro de
titulo. El Compromiso es un documento legal. Usted debe
leerio cuidadosamente y entendario completamente antes de la
fecha para finalizar su transaccion.
Your Commitment for Title Insurance is a legal contract between you and us . The Commitment is not an opinion or report of your title . It is a contract to issue you a
policy subject to the Commitment's tenns and requirements .
Before issuing a Comm itment for Title Insurance (the Commitment) or a Title .Insurance Policy (the Policy}, the Title 1nsurance Company (the Company) detennines
whether the title is insurable . This detenn ination has already been made . Part "ofthat detennination involves the Company's decision to insure the title except for
certain risks that will not be covered by the Policy . Some of these risks are listed in Schedule B of the attached Commitment as Exceptions . Other risks are stated in
the Policy as Exclusions . These risks will not be covered by the Policy.
Another part of the determination involves whether the promise to insure is conditioned upon certa in requirements being met. Schedule C of the Commitment li sts
these requirements that must be satisfied or the Company will refuse to cover them. You may want to discuss any matters shown on Schedules Band C of the
Comm itment with an attorney . These matters will affect your title and your use of the land .
When your Policy is issued , the coverage will be limited by the Policy's Exceptions , Exclusions and Conditions , defined below .
-EXCEPTIONS are title risks that a Policy generally covers but does not cover in a particular instance . Exceptions are shown on Schedule B or discussed
in Schedule C of the Commitment. They can also be added if you do not comply with the Conditions section of the Commitment When the Pol icy is
issued , all Exceptions will be on Schedule B of the Policy.
-EXCLUSIONS are title risks that a Policy generally does not cover . Exclusions are contained in the Policy but not shown or discussed in the
Commitmen t.
-CONDmONS are additional provisions that qualify or limit your coverage . Conditions include your responsibilities and those of the Company. They are
contained in the Policy but not shown or discussed in the Commitment . The Policy Conditions are not the san1e as the Commitment Conditions .
You can get a copy of the policy form approved by the State Board of Insurance by calling the Title Insurance Company at or by calling the title insurance agent that
issued the Commitment The State Board oflnsurance may revise the policy fonn from time to time .
You can also get a brochure that explains the Policy from the Texas Department of Insurance by calling 1-800-252 -3439.
Before _the Policy is issued , you may request changes in the Policy . Some of the changes to cons ide r are:
-Request amendment of the "area and boundary" exception (Schedule B, paragraph 2). To get this amendment, you must furnish a survey or comply with
other requirements of the Company. On the Owner Policy, you must pay an additional premium for the amendment. If the survey is acceptable to the
Company or if the Company's other requirements are met, your Policy will insure you aga inst loss because of discrepancies or conflicts in boundary lines,
encroachments or protrusions, or overlapping of improvements . The Company may then decide not to insure against specific boundary or survey problems
by making special exceptions in the Policy. Whether or not you request amendment of the "area and boundary" exception , you should determine whether
you wan t to purchase and review a survey if a survey is not being provided to you .
-Allow the Company to add an exception to "rights of parties in possession ." If you refuse this exception , the Company or the ti tl e insurance agent may
inspect the property . The Company may except to and not insure you against the rights of specific persons, such as renters , adverse owners or easement
holders wh o occupy the land . The Company may charge you for the inspection . If you want to make your own inspection, you must sign a Waiver of
lnspect ion fonn and allow the Company to add this except ion to your Policy .
TI1e entire premium for a Policy must be paid when the Policy is issued . You will not owe any add itional premiums unles s you want to in crease your cove ra ge at a
later date and the Company agree s to add an Increased Value Endorsement.

DELETION OF ARBITRATION PROVISION
(Not Applicable to the Texas Residential Owner Policy)
Arbitration is a common form of alternative dispute resolution. It can be a quicker and cheaper means to settle
a dispute with your Title Insurance Company. However, if you agree to arbitrate, you give up your right to
take the Title Company to court arid your rights to discovery of evidence may be limited in the arbitration
process . In addition, you cannot usually appeal an arbitrator's award .
Your policy contains an arbitration provision (shown below). It allows you or the Company to require
arbitration if the amount of insurance is $2,000,000 or less. If you want to retain your right to sue the
Company in case of a dispute over a claim, you must request deletion of the arbitration provision before
the policy is issued. You can do this by signing this form and returning it to the Company at or before
the Closing of your real estate transaction or by writing to the Company.
The arbitration provision in the Policy is as follows:
"Either the Company or the Insured may demand that the claim or.controversy shall be submitted to arbitration
pursuant to the Title Insurance Arbitration Rules of the American Land Title Association ("Rules") .. Except as
provided in the Rules, there shall be no joinder or consolidation with claims or controversies of other persons.
Arbitrable matters may include, but are not limited to, any controversy or claim between the Company and the
Insured arising out of or relating to this policy, any service in connection with its issuance or the breach of a
policy provision, or to any other controversy or claim arising out of the transaction giving rise to this policy.
All arbitrable matters when the Amount of Insurance is $2,000,000 or less shall be arbitrated at the option of
either the Company or the Insured, unless the Insured is an individual person (as distinguished from an Entity).
All arbitrable matters when the Amount of Insurance is in excess of $2,000,000 shall be arbitrated only when
agreed to by both the Company and the Insured. Arbitration pursuant to this policy and under the Rules shall
be binding upon the parties. Judgment upon the award rendered by the Arbitrator(s) may be entered in any
court of competent jurisdiction."
I request deletion of the Arbitration provision.

Re: Capstone Development Preliminary Trip Generation Report
Dear Ms. Morgan:
As per your request I have developed some trip generation and directional assignment
numbers for the proposed development. These numbers are based on the conceptual site plan you
provided, a copy of which is attached to this report as Figure 1. If the site plan changes considerably
the analysis will have to be redone based on the actual development proposal. It is assumed for this
preliminary report that the reader is familiar with the general location of the development.
The general area for this proposed development is bounded by FM 2818 on the north. The
areas to the south and southwest of the development area are generally residential in nature with
several subdivisions present and additional residential development proposals currently possible.
Tue primary existing roadway under consideration herein is Jones-Butler Rd. which connects to FM
2818 and continues north across that highway toward Texas A&M University. Dowling Rd. also
abuts the property and heads southwest into additional residential areas .
The task identified for this analysis was to determine the average daily traffic (ADT)
volumes which would be produced by the proposed development. These volumes are the added
volumes over and above the existing volumes which are present on Jones Butler Road and Dowling
Road at this time. The projected volumes represent the condition at build out, which will obviously
not be reached immediately. The volumes developed are then be compared to the capacities
presented in the Bryan-College Station Unified Design Guide for Streets for the various roadway
classes identified to determine capacity will be consumed by this development. Please recognize
that the actual capacity of a roadway, such as the ones under consideration herein, is largely
controlled by the intersection capacity at adjacent intersections. The intersection capacity is based
on the geometrics and type of control at the intersection and the conflicting volumes. Intersection
capac ity is beyond the scope of this initial assessment.
This assessment was produced in essentially three parts. The first is the trip generation
wh ic h is shown for ADT on Figure 2 and for Peak Morning Hour as Figure 3. The data is broken
down into small areas as shown on Figure 1 and is presented in tabular form . Both tables are based
on a determination of the number of actual beds (persons) in each sub-area identified, based on the
building type, and the trip generation rates taken from the Institute for Transportation Engineers
(ITE ) Trip Generation data (7th ed .). This resource compiles data for numerous trip generation

studies from around the United States and includes a number of potential land uses, each of which
is numbered for reference. For this study the residential land use for Apartments (220) and Low
Rise Apartments (270) were considered. The data is given for ADT and for the morning peak
period, which is estimated to be the largest peak hour for this development. The commercial
development is non-specific in type at this point and was analyzed as generic Shopping Center
(820). Average values are used for each type.
Commercial development typically generates some new traffic but also captures some of the traffic
that is already on the roadway, or in this case, generated by this proposed additional residential
development. The interest in this study is for the new additional trip generation so the raw trip
generation numbers are reduced by a "Passerby Percentage". These reductions are shown in the trip
generation tables only for the commercial traffic since the residential traffic will generate totally
new volumes. The passerby percentage used in this analysis is 35% for the ADT and 45% for the
peak hour. These values should be reasonably accurate since the commercial development is not on
a major thoroughfare. The peak hour passerby figure is higher since the morning peak is the larger
and captured traffic is higher at that time since there are less general shoppers out then. Diverted
link trips are not analyzed in this report as they are beyond the scope of this preliminary analysis.
The trip generation is summarized on Figures 2 and 3. The total additional ADT expected from this
development is about 8400 Vehicles per Day (VPD). The comparable maximum hourly volume
generated is about 644 Vehicles per Day (VPD).
Tue second task was to assign the newly generated traffic volumes to the driveways and roadways
in question. These driveways have been labeled on the site plan shown in Figure 1. The
development area ~as broken down in to contributory sub areas, much like a drainage analysis is
done . In this case tbe assignment of traffic from a particular area is somewhat subjective based on
the judgement of the author and experience in the field. Generally traffic will seek the path ofleast
resistance when entering and leaving a development area. In this case, the primary access location
will be from FM 28 18 via the traffic signal at Jones Butler Rd. Traffic entering the development
will practically take the shortest route allowable and has been assigned that way. Traffic leaving
the development has to compete with existing traffic on the roadways and with other traffic leaving
the development. This typically produces a slightly more varied distribution where the shortest path
in distance is not necessarily the shortest path in time . For example, traffic exiting area #5 would
exclusively use Do'1'ling Rd ., whereas traffic from area #15 must choose between driveways 2, 3
and Dowling Rd ., depending on the traffic conditions expected. The Directional Assignment data
for ADT is presented in Figure 4. The traffic assignments assume that all outbound traffic from the
residential area of this development uses Jones-Butler to the north. This assumption is based on the
type of developmen1 in this proposal and the type of existing development to the south.
These data show total additional trips on Jones Butler of 8398 VPD and for Dowling Rd. of
1362 VPD. These compare to existing (2006) volumes of3 818 VPD on Jones Butler and 3604 VPD
on Dowling Rd. The existing volumes were provided by Troy Rother, of the City of College Station
staff, based on a 2006 traffi c count in the area in question .
The third area of work includes a comparison of projected volumes to the prescribed
volumes for the given roadway classifications included in the Street Design Guide mentioned above
and included attached to this report. The range of volumes for a Major Collector is from 5000-1000
VPD . The range of volumes for a Minor Arterial is from 5,000 to 30,000 VPD . Generally roadway

classification is based on roadway function which is affected by trip type and trip length. A
development such as the proposed one generates substantial traffic, but requires only a major
collector type street to allow access to the roadway network. For this development that trip is short,
essentially the distance to FM 2818. The traffic volume generated by this development contributing
to Jones-Butler falls primarily in the range for a Major Collector street which geometrically and
functionally would meet the needs of this development. The approaches to a signalized intersection
would be satisfactory as well with two approach lanes for the volumes presented here for this
development. While Jones-Butler may eventually function as a minor arterial because of trip length,
it will not do so based on this development.
The specified capacity of a minor collector street is 1000 to 5000 VPD. The trip generation
by this development which will contribute to Dowling Rd. is comfortably within this range.
Functionally, the traffic generated by this development using Dowling Rd. only needs a minor
collector for that service.
This completes the presentation of the preliminary analysis of this proposed development.
Tue conclusions presented below summarize the material contained in the body of the report.
Conclusions
1. The trip generation for this development proposal should be approximately 8400 VPD with
a morning peak of about 644 VPH.
2. Of these trips about 1263 will use Dowling Road and all 8400 will use Jones-Butler Road.
3 . This development justifies the use of major collector geometrics on Jones-Butler and minor
collector geometrics on Dowling Road.
If you have questions regarding this information please direct them to me at your
convemence.
Sincerely,
Jeffrey T. Milburn, P.E.

The Cottages of Colleg e Station Drainage Analysis
I NTRODUCTION
The purpose of this drainage report is t o pre sent an ana lysis of the n ec ess ary drainage
infrastructure for the proposed street syst em which entai ls Holleman Driv e, Market Street,
Manor Avenue, and Cottage Lane . The new street system will be located in south College
St ation, nea r Harvey Mitchell Pkwy (FM2818) and Jone s-Butler Road . The newly
con structed ro ads include extending Holle m an Dr ive from FM 2818 ultimately to Jones -
Butler Road . The proposed Market Stree t , Manor Avenue , and Cotta ge Lane will be
connected to the newly construct ed Hollem an Drive . The drainage report provides a flood
analysis extending onto the site property and analy sis for the infrastructure required for
removal of on site flow . The report includes the analy sis of the 52 .045 acre property .
GENERAL LOCATION & DESCRIPTION
The proposed Ho ll eman Dr ive extension , Manor Avenue, Market Street, and Cottage Lane
will be located in College Station, Te xas, south of Harvey M itchell Pkwy S (FM2818),
connect ing FM 2818 to Jones-Butler Road . The site is currently undeveloped. The
development is situated at the top of the White Creek Drainage Basin. The site will gain
driveway acce ss from FM 2818 and Jones-Butler Road . Manor Avenue and Market Street
will gain access from the newly constructed Ho lleman Driver . Cottage Lane will gain access
from Manor Avenue and Market Street. The propo sed deve lopment includes the extension
of Holleman Drive and addition of Market Street, Manor Avenue, and Cottage Lane .
Additio nally, the development will include the construct ion of storm sewer systems for
remova l of on site flow . Onsite flow from these street sys t ems only w ill be discharged un-
attenuated to White Creek Unnamed Tributary . Furthermore, two proposed cu lverts will be
const r uc t ed to convey flow from Unnamed Tributary due to construction of the Holleman
Dr ive extension . Please see Exhibit 1 for Genera l Locat ion Map .
DRAINAGE DESIGN CRITERIA
All drainage de sign is in accordance with the Bryan/College Station USDG . As such :
• Design rainstorm events consist of the 2-, 10-, 25-, 50 -and 100-year, 24 hour
duration hypothetical frequency storm events in order to ana lyze the effectiveness
of the detent ion faci lities as well as capt u re conserva ti ve peak flow va lues .
• Fl ow calculations are based on the Soi l Conservat ion Service Curve Number Loss
M ethod . Curve Numbers are based on soil type and land use in the subbasins and
imperv ious cover data was used to calculate percent imperv ious .
• The ta rget peak runoff rate for the post-development condition is that of the pre -
development peak flow rate at the study confluence .
The analysis confluence for the study is identified as White Creek Unnamed Tributary
located on the west property line of the subject tract. The effects of the proposed
development at the study confluences wil l be considered in determining whether the des ign
objectives were sat isfied .
PRIMARY DRAINAGE BASIN DESCRIPTION
The proposed project site is located within the White Creek Drainage Basin . As
demonstrated i n Exhibit 2 . 1, a smal l portion of the property lie s within the regulatory 100-
year floodpla in per the Federal Emergency Management Agency (FEMA ) Flood Insurance
Rate Map (FIRM ) panel 0182C, with an effective data of May, 22 , 2008 . With the adoption
of the LOMR on May ~2, 2008, the floodpl ain was no longer extended on Tributary 1 and 3

Drainag e Rep ort
in the su bje ct tract. On ly in the Unnamed Tributary did FEMA retain the approximated
Zone A de signation. Per FEMA regulation s con tain ed in 44 CFR 60 .3(b) (3) "Requi re that all
new subd ivision proposals and other proposed developments (including proposals for
manufactured home parks and subd ivi sions) great than 50 lots or 5 acres, whichever is the
lesser , inclu de within such proposals ba se flood elevation data ." To comply with this
section, thi s flood study will define the existing 100 year flood boundary but w ill not be
submitted for regulatory flood mapping . The flood study will be discussed in the
subsequent se ction of this report.
Current ly , there are no offsite drainage sources to the site . All drainage areas will be
located on si te and will drain we st, northwest to one of three tributaries of White Creek .
The flood study will be completed for all three tributaries. For the purpose of this drainage
report, the focus will be on the Unnamed Tributary of White Creek due to the location of
the proposed roadways . The site consists of grasslands and approximately 50% tree cover .
The tree cover is mainly concentrated along the tributaries of White Creek. Percent
impervious cover for the site will be computed for the pre -development and the post-
development conditions .
FLOOD BOUNDARY ANALYSIS PER EXISTING CONDITIONS
General In formation
The flood study discussed in this section will be an extension of a prev io usly determined
f lood analysis for the adjacent property, Place Propertie s, performed by Dodson A ssoc iates.
The Place Properties flood study (LOMR Case #07-06 -1353P) ends on the west property line
of the subject tract. The existing flood boundary shown on FIRM 0812C was adjusted and
updated with the Place Properties flood study. It was determined that the onsite flood
boundary as identified on FIRM 0812C was inaccurately located. Therefore, the purpose of
this flood study is to accurately locate the flood boundary area . This flood study will be
developed by using steady flow modeling . To complete the Capstone flood study, water
surface elevations per Place Properties flood study will be used as a downstream boundary
condition . The developed model will match the existing water surface elevations located at
the west property line of the site . See Table 1 for existing water su rf ace elevations used as
downst ream boundary conditions .

Drainage Patterns-Existing Conditions
Initially, drainage areas were determined by subbasin divides and location of tributaries .
Exhibit 3 illustrates the existing drainage basins used for determining hydrologic
parameters . Existing Drainage Area 8 will drain off site to Dowl ing Road and will not affect
the study of Tributary 1, Tributary 3 and Unnamed Tributary .
Hydrologic Analysis-Existing Conditions
For the purpose of this analysis, Flood Boundary Analysis, storms were generated for all
studied rainfall events using the depth-duration data taken from the National Weather
Service TP-40 . Using HEC-HMS, the storms generated were used for both the pre-and
post-development analyses. Pre-and post-development hydraulic mode ling was performed
for all specified rainfall events and included the required 2-through 100-year rainfall events
specified by Bryan/College Station USDG . Results can be found in Exhibits 8 .2 -8.7. Peak
drainage area flows were used as input parameters for the steady flow model. Runoff
losses due to infi ltration and initial abstractions were calculated using the SCS (NRCS) Curve
Number Loss Method. The se parameters were calcu lated using the Curve Number,
established from soil type in the Brazos County Soil Survey, and percentage of impervious
cover in the basins . The project drainage basin consists of Type D soil with a Curve Number
of 75 for Antecedent Moisture Condition (AMC) II. Direct runoff hydrographs were
generated using the calculated runoff depths and the SCS dimensionless unit hydrograph .
See Exhibit 8 . 1 for basin parameters used in the hydraulic model ing.
Hydraulic Analysis-Existing Conditions
It was initially assumed that the flood analysis study performed by Dodson Associates for
the adjacent property would be extended through the site property . However, after
The Cotta ges o f Co ll ege Station- Stree t Desig n
Drainage Rep ort

determining the drainage areas for the three onsite tributaries, it was determined that no
addition area, other than the site property, would drain to the tributar ies. Therefore, a
separate HEC-RAS model will be constructed for the tributarie s lo cation on the site property
and flood boundaries will be determined . As previously m entioned , water surface
elevations determined from the flood study for Place Properties at the site property line will
be used as downstream boundary condition s.
Cross sections were entered left to right, facing down stream. Cro ss sections are in serted at
changes in the channel to achieve opti mum channel character istics . Change s in the
channel result from a change in discharge, slope, shape, roughness, and hydraulic
structures . Also, they are constructed perpendicular to the flow line and were placed in a
manner to avo id overlap . The channel is not straight, so the cross sections are not parallel
to each other, resulting in different downstream re ach length s for right, left and channel
overbanks .
Once the geometry was defined, steady flow data was calculated for all storm events . The
pea k flows for each drainage subbasin would be intro duced into the model at a point of
intersection between the subbasin and the tributaries . Typically, the most downstream
point of intersection was used an insert ion location of peak flow data . Table 2 . 1 below
contains the flows used at cross sections throughout the three tributaries.

Due to the short length of the reache s and the steepne ss of the channel flowline, mi xed
flow regime was used . Therefore, sub-critical and super-critical flows are present in the
m o del. For a mi xed flow regime to work correctly, an upstream boundary condition ha s to
be defined . To satisfy this, normal depth was used . Normal depth was approximated with

the average slope of the reach . With the geometry, steady flow data, and boundary
conditions defined, the model was used to generate flood boundaries for the property .
Exhibit 2.2 illustrates these flood boundaries for the existing conditions. Modeling outputs
and profiles can be seen in Appendix B.
STORMWATER RUNOFF ANALYSIS
STREET DESIGN ONLY (Holleman Dr., Manor Ave., Market St., & Cottage ln.)
General Information
For the purpose of this drainage report, the focus will be on the location of the proposed
roadways which will affect the Unnamed Trib utary of White Creek. A proposed drainage
report will be generated at a later date for the development of the Cottages of College
Station Site Plan and the effects on Tributary 1 & 3.
Proposed Drainage Patterns
With the proposed development of the four streets and the future development of the
Cottages of College Station, proposed drainage areas were developed. For the proposed
analysis, the area of focus will be the drainage areas that will affect the Unnamed Tributary
of White Creek (see Exhibit 3).
Post-Development Drainage Basin
The development of the proposed roadways will result in a reasonable addition of
impervious cover. However, as seen on Exhibit 3, a large amount of drainage area has been
diverted from the Unnamed Tributary of White Creek to the tributaries 1 & 3 . Therefore,
even with the increase in impervious cover, there will be no increase of the peak flow rate
in the Unnamed Tributary from the site . With reduced peak runoff rates, the runoff
produced from development of the streets will be released un-detained. See Table 3 for a
comparison of the existing and proposed peak flow rates at the most downstream cross
section of the Unnamed Tributary .

The post-development analysis of this development included the drainage areas located
within the area of focus as seen in Exhibit 3 . As previously mentioned, the SCS curve
numbers remained the same while the percentage of impervious cover increased on the
project site within the majority of the subbasins. One subbasin, DA 64 will drain offsite,
while the majority of drainage subbasins will remain undeveloped and unchanged .
Proposed stormwater pipe will be used to remove runoff from the developed streets. There
will be five outfall points of discharge into the Unnamed Tributa ry. Three of the outfall
points will be located near the most upstream section of the reach . The remaining two
outfall points will be the proposed culverts 1 & 2 as previously mentioned. Exhibit 3
illustrates the point of discharge into the Unnamed Tributary.
Stormwater infrastructure was sized based on rat ional method flows. See Exhibit 4 for
runoff peaks for each drainage area and Exhibit 5 for pipe sizes calculated from runoff

peak s. HGL calculations were found for the stormwaterr system for the 10 -and 100-year
sto rm events . Tai lwater elevations for the stormwaterr system were based upon calculated
water surface elevat ions in the cu lvert. The water surface within culvert 2 was assumed to
be the soffit elevat ion w ithin t he culvert. Thi s assumption was made d ue to culvert 2 being
construct ed by others as mentioned later in thi s section . See Exh ibit 7. 1-7 .2 for HGL
calculat ions of proposed stormwater pipe . Stormwater prof ile s, including HGL calculations
can be found in Exhibits 7 .3-7.4 and road profiles for Holleman Drive and Manor Avenue .
In let capacity calculation s (Ex hibit 6. 1 &6.2) were performed for the 10-and 100-year storm
events to si ze proposed curb and grate in lets. Peak runoff rate s were calculated us ing the
Rationa l Method (Exhibit 4 ) and used to size the inlets. All curb inlets will be standard 5',
1 O' and 15' inlets .
Hydrologic Analysis-Proposed Conditions
For the purpose of th is analysis, si z ing the propo sed cu lverts cro ssing Holleman Drive,
storms were generated for all stud ied rainfall events usi ng the depth-duration data taken
from the National W eather Service TP-40. Us ing HEC -HMS, the storms generated were
used for both the pre-and post-development analyses. Pre -and po st -development
hydraulic modeling was performed for all specified ra i nfall events and included the required
2-through 100-year rainfal l events specified by Brya n/College Station USDG . Results can be
found in Exh ibits 8 .2-8. 7. Peak drainage are a flows were used as input parameters for the
steady flow model. Runoff losses due to infiltration and in itial abstractions we re calculated
us ing t he SCS (NRCS) Curve Number Loss Method . These parameters were calculated using
the Curve Number, establi shed from soil type in the Br azos County Soi l Su rvey, and
percentage of impervious co ver in the basins. The project drainage basin cons ist s of Type D
so il with a Curve Number of 7 5 for Antecedent M oisture Co ndition (AMC) II. Direct runoff
hydrographs were generated using the calculated runoff depths and the SCS dimensionless
un it hydrograph . See Exhibit 8 . 1 for basin parameters used in the hydraulic modeling .
Proposed Culvert
In designing the proposed culverts located on Holleman Drive, closest to FM 2818, HEC-
RAS was used in the sizing calculations . As mentioned ear lier, storm w ater pipe was sized
based on rationa l method . In determining the peak flows for flood ana lysis, the CN method
was im pl emented in HEC-HMS . W ith a con fl ict in meth odology, the drainage areas
correspo n ding to the stormwater system was me rged with t he undeveloped drainage areas
(see Exhibit 8 . !-Description). New peak flows were determined and used in a proposed
model for the Unnamed Tributary to Wh ite Creek . See Tab le 4 for peak flows and location
of insert ion into the HEC-RAS model.

In this proposed model, culverts were introduced at two locations on the proposed
Ho ll eman Dr ive . These two locations are labeled as Culverts 1 & 2 in Exhibit 3 . Once the
cu lverts were entered into the model, an iterative process was used in calculating the size of
the culverts . Final sizing was determined by the 100 year water surface elevation . The 100
year water surface elevation would not exceed to the road elevation . Due to the soil
condition currently located at the site and the susceptibility to erosion, erosion control
measures were taken . Culvert 1 was sized to be a 7' x S' RC box culvert. Dissipator blocks
wi ll be used at the downstream of the culvert. Additionally rip -rap will be present on both
upstream and downstream ends of the culvert. Culvert 2 located upstream near Market
Street and Holleman Drive was modeled to be a 6 ' x 5' RC box culvert. However, per the
location and extent of construction, the second culvert will be constructed by McClure
Engineer ing with the second construction phase of Holleman Dr ive, extending it to Jone s-
But ler Road.
In siz ing culvert 1, part of our design work, culvert 2 was defined to have a slope similar to
the ex isting ground . With a lack of geometry informat ion just upstream of culve rt 2, due to
an ex isting stock pond, a best approximation was used to define cross sectional geometry
just upst ream of cu lv ert 2. By vi ewing Exhibit 9, a hydraulic ju mp is present in the profil e of
the water surface elevations through culvert 2 . Th is is partially due to unknown reach
flowline elevations just upstream of the proposed culvert. However, the presence of the
second culvert in the HEC-RAS model was necessary to correctly size culvert 1.
Downstream effects of culvert 2 were needed to properly model culvert 1. All proposed
conditions output data from HEC-RAS can be found in Exhibit 9 as well.
CONCLUSION
Although the development of the new extension of Holleman Drive and addition of Market
Street, M anor Avenue, and Cottage Lane will increa se volume of runoff from the site, the
changes in drainage patterns will result in no attenuation needed for the effects of the
development of this tract (see Table 2). The changes in the dra inage patterns that occur as
the result of develop ing the tract will not have adver se effects on the properties
surrounding the Cottages of College Stat ion site .
