SANITARY SEWER DESIGN REPORT
Introduction
The proposed site will consist of 0 .937 AC of multi -family residential development. The
proposed Sterling Heights Apartments will contain 24 units and 40 total bedrooms .
Wastewater from the site will be collected into a cleanout which connects to a proposed
6" sanitary sewer service. The proposed service will tie into an existing 6" sanitary
sewer line that runs eastward along the rear of the property. The locat ion of the
proposed service is shown in the site plan attached in Exhibit 1.
Analysis of Proposed Systems
As d iscussed in the introduction, wastewater from the site will be collected into the
existing 6" sanitary sewer line south of the site. The flow generation for the system was
calculated using the fixture unit method, as outlined in the BCS Unified Design
Guidelines, wh ich specifies a load factor per fixture. This factor is then multiplied by the
number of fixtures to find the total number of fixtu re units . Table II in the BCS Unified
Guidelines was used to find the total number of gpm per fixture. The contribution of
flows within the proposed site was determined using the method shown below:
Sterling Heights Fixtures
• 24 kitchen sinks @ 2 units per each
• 40 showers/baths @ 2 units per each
• 40 toilet @ 2 units per each
• 40 vanity sinks @ 2 units per each
• 24 washing machines @ 4 units per each
• 24 dishwashers @ 2 units per each
Total proposed flow:
Total fixture units: 432
Total peak flow : 125gpm/500units (Table II of BCS Unified)=
.25gpm per fixture unit=.25(432) = 108 gpm = 0 .24 cfs

RE: Revi sed Ster ling H eights Fire Flow Analysis
Dear Erika,

Bryan, Texas 77802
Tex. Reg. No. F-678
As requested the fire flow capacity from the exi sting City of College Station 6" AC waterline on the north
side of Sterling Stree t to the propos ed Sterling Heights d eve lopment ha s been analyzed . The subject tract is
loca ted on 218 Sterling Street in College Station approximately two blocks south of Holleman on the east side
of Texas Avenue.
A fire flow tes t was completed by th e City of College Station on a fire hydmnt located adjacent the property
at 211 Sterling Street. This fire hydrant is known as FH (E-151) under the Ci ty of College Station
nomenclature . Fire Hydrant (E-012) was also an alyzed during this flow test for static and residu al pressures
while FH (E-151 ) was fl owed . The fire hydran t fl ow tes t is su mmarized in Table 1 below as well as attached
for your reference .

The existing City of College Station waterline was modeled in Bentley WaterCad V8i to determine th e
available amount of fire flow to the proposed development. A schematic layo u t of the model and th e
WaterCAD input and output d ata is attached for your reference . The fir st step in the modeling proc ess was to
calibrate the model to accurately represent the flo ws and pressures determined during the fire flo w test. First
the model was set up to have a static pres sure in the system of 100 psi as determined in the fire flow test. The
approximate elevation of the exi sting line at this lo catio n i s 300'. A pressure h ea d of 531 ' was assigned to the
reservoir, "R-1 '', serving our model. Tlus difference in pres sure head is 231 ' or exactly 10 0p si. A reservoir was
used to recreate the static pressure found in FH (E-112) simplifying the model to avoid recreating the system
upstream of our area of concern . R-1 represents pressures served by tl1e City of College Statio n water sy stem .
The second calibra tion was d one was to ensure that FH-(E-151) wa s left with a p re ssure of 70psi when
flowing at 1,455gpm. This was comple ted by ass igning a calculated lengtl1 to P-1, the pipe connecting "R-1"
and FH-(E-151 ). This calculated length created the head loss required to decre ase the pressure in FH-(E-151)
to 70 psi when flowing at 1,455gpm. This length , although arbitrary in itself, represe nts the headlo ss

determined in the City of College Station fire flow te st through the existing piping, bends , etc . thus
simplifying the model.
Once the model wa s calibrated a single fire flow analysi s was completed of the subject development with a
single fire wall . The results the scenarios are summarized in Table 2 below.

Notes:
(1) The average velocities were determined by taking the velocity in P-1 and dividing it by two. Currently the Bleyl
& Associate> model only feeds FH(E-151) from one direction . Th.is assumption was made knowing that the
actual distribution system feeds FH(E-151) from both directions creating a looping system. The flow was
assumed to be fed evenly from b oth side of the distribution system in fire flow conditions thus decreasing the
ve loci ty in each supply pipe by half. The BCS Unified Guidelines limit velocities in a main to 12ft/sec under
fire flow conditions. The maximum velocity may be increased on a case by case basis.
The single fire wall sce nario anal yz ed the proposed development as a "double " unit with .QDS fire wall . As
previously stated the proposed apartments are a 28,861 SF Type V-B construction development. Under the
International Building Code (IB C) a Type V-B construction area between 15,601SF-18,000SF requires
3,500gpm of fire protection. Since this de v elopment will include fire protection sprinklers the required fire
flow can be reduced by 50 % to 1,7 50gpm. Under a fire fl ow analysis of 1,750 gpm, including residential and
fire sprinkler demand, a minimum press ure of 44 psi was maintained at FH(E-151) and the proposed Sterling
Heights development.
To summarize, the analysis proves that if the buil ding is constructed as proposed with 28,861SF, Type V-B
construction, 108 gpm maxi.mum re sidential demand, and 180gpm fire sprinkler demand that one fire wall
will be required to meet fire flow regulations. Under these condition s 1,750 gpm of fire flow will be required
which would leave a pressure of 44psi in the distribution system. Under this flow scenario the velocity in the
existing 6" main wou ld be 11.569ft/sec which under the 12ft /sec limit.

SANITARY SEWER DESIGN REPORT
Introduction
The proposed site will consist of 0.937 AC of mult i-family res idential development. The
proposed Sterling Heights Apartments will contain 24 units and 40 total bedrooms.
Wastewater from the site will be collected into a cleanout which connects to a proposed
6" sanitary sewer service . The proposed service will tie into an existing 6" sanitary
sewer line that runs eastward along the rear of the property . The location of the
proposed service is shown in the site plan attached in Exhibit 1.
Analysis of Proposed Systems
As discussed in the introduction , wastewater from the site will be collected into the
existing 6" sanitary sewer line south of the site. The flow generation for the system was
calculated using the land use determination method , as outlined in the BCS United
Design Guidelines, which specifies a residential population factor of 2 .67 capita per unit.
This factor is then multipl ied by the residential average flow generation per capita of 100
GPO. The contribution of flows within the proposed site was determined using the
method shown below:
Sterling Heights
• 2.67 persons per unit
• 100 gallons per day per person
• 24 units
• Peaking Factor= 4
Total proposed flow:
Residential lot average flow: (2.6 7 p ers.onx 10 0 gpd J = (267 gp~ x 24 units J
unit p erson urut
= 6 ,40 8gpd = 4.45 gpm
Total peak flow : 4.4 5 gpm (4 ) = 17 .8 gpm = 0.04 cfs
Mann ing 's equation was used to calculate the capacity of the proposed 6" sanitary
sewer service line. The slope of the service line was designed at 1 %.

As shown in the calculations above the proposed sanitary sewer service line has
adequate capacity to serve Sterling Heights. Using these flows, the City can verify the
capacity of the existing 6" sanitary sewer line to serve the proposed development.

As requested the fire flow capacity from the existing City of College Station 6" AC waterline on the north
side of Sterling Street to the proposed Sterling Heights development has been analyzed. The subject tract is
located on 218 Sterling Street in College Station approximately two b locks south of Holleman on the east side
of Texas Avenue.
A fire flow test was completed by the City of College Station on a fire hydrant located adjacent the property
at 211 Sterling Street. This fire hydrant is known as Ff--{ (E-151) under the City of College Station
nomenclature. Fire Hydrant (E-012) was also analyzed during this flow test for static and residual pressures
while FH (E-151) was flowed . The fire hydrant flow test is summarized in Table 1 below as well as attached
for your reference.

111e existing City of College Station waterline was modeled in Bentley WaterCad V8i to determine the
available amount of fire flow to the proposed development. A schematic layout of the model is attached for
your reference. The first step in the modeling process was to calibrate the model to accurately represent the
flows and pressures determined during the fire flow test. First the model was set up to have a static pressure
in the system of 100 psi as determined in the fire flow test. Tbe approximate elevation of the existing line at
this location is 300'. A pressure head of 53 1' was assigned to the reservoir, "R-1", serving our model. This
difference in pressure head is 231' or exactly l OOpsi. A reservoir was u sed to recreate the static pressure found
in FH (E-112) simplifying the model to avoid recreating the system upstream of our area of concern. R-1
represents pressures served by the City of College Station water system.
The second calibration was done was to en sure that FH-(E-151) was left with a pressure of 70psi when
flowing at 1,455gpm. This was completed by assigning a calculated length to P-1, the pipe connecting "R-1"
and FH-(E-151). This calcu lated le ngth created the head loss required to decrease th e pressure in FH-(E-151 )
to 70 psi when flowing at l,455gpm. This length, although arbitrary in itself, represents the headloss
detem1ined in the City of College Station fire flow test through the existing piping, bends, etc. thus
simplifying the model.

No tes:
(1) The avera ge velocities were determin ed by taking the velocity in P-1 and dividing it by two. Currentl y th e Bl ey l
& Associates model onl y feed s FH(E -151 ) fr om one direction . Thi s ass umption wa s made knO\ving that th e
actual di stribution sys tem feed s FH(E -151 ) from both directions creating a looping sys tem. The flow was
ass umed to be fed evenl y from both side of the di stribution sys tem in fire flow condition s thu s decreas ing the
velocity in each su pply pipe by half. The BCS Unified Guidelines limit velocities in a main to 12ft /sec under
fire flow conditions. Th e maximum velocity may be increas ed on a ca se by case ba sis.
The first sce n ario was "Ultim ate Fire Flow" and analyze d the maximum fire flow that could be harnes sed
from the existing lin e. Under TCEQ nile 290.46 (r) a minimum press ure of 20 p si is required during fire fl ow
conditio ns. This r equirement is al so adhered to b y the BCS Unified Guidelines . It was determined th a t a
maximum fire flow of 2,280 gpm could be pulled from FH (E-151 ) and maintain 20psi in the di stri bution
sys tem. This fire flow scenario also took into account the peak re sidential demand of 17.8gpm and the fire
sprinkler demand of 180 gpm.
The second scenario analyzed was the development as a single unit with .!1Q fire walls. The proposed
apartments are a 28,861 SF Type V-B construction development. Under the International Building Code
(IBC) a Type V -B construction area between 26,301SF-29,300SF requires 4,SOOgpm of fire protection. Since
this develo pment will include fire protection sprinklers the required fire flow can be reduced b y 50% to
2,250gpm. Under a fire flow analys is of 2,250gpm, including residential and fire sprinkler demand, a
minimum pres sure of 22psi wa s maintained at FH (E-151 ) and the propose d Sterling Heights dev elo pment.
The third scenario analyze d w as the development as a "double" unit with one fire wall . As previously stated
the proposed apartments are a 28 ,8 61 SF Type V -B cons truction development. U nder the Interna tional
Building Code (IBC) a Type V -B construction area between 15,601SF-18,000SF requires 3,500gpm of fire
protection . Since thi s development will include fire protection sprinkler the r eq uir ed fire flow can be reduced
b y 50 % to 1,750gpm. Under a fire flow anal ys is of 1,7 50 gpm, including r esiden tial and fire sprinkler dem and,
a minimum press ur e of 49 p si was maintained at FH(E-151 ) and the propos ed Sterling Heights development.
To summarize, the an al ys is proves that if the building is cons tructed as proposed with 28 ,861SF, Type V -B
cons truction, 17.8pgm maximum r esid ential d emand , an d 180gpm fire sprinkler demand that no fire wall will
be required to meet fire flow regu lation s. Under these conditions 2,250 gpm of fire flow will be required
which would leave a pressure of 22 p si in th e dis tribution sy s tem. Und er this flow scenario the velocity in the
exi s ting 6" main would b e 13.89ft/sec which is 1.89ft/sec above the 12 ft/sec limit. A discu ss ion would be
r equired with the City to see if this velocity would be accep ted.
If a fire wa ll is considered and 1,7 50gp m is u sed a pressure of 49gpm wou ld be left in the distribution sy s tem.
Under this fl ow scenario the velocity in the existin g main would be 11.05 ft/sec .

Notes:
(1) The average velocities were determin ed by taking the veloci ty in P-1 and dividing it by two . Currentl y the Bley l
& Associates model only feed s FH(E-151) from one direction. This ass umption was made kno ... ving that th e
actual distribution syste m feeds FH(E -15 1) from both directions cre ating a looping system . The flow was
assumed to be fed evenly from both side of the distribution sys tem in fire flow conditions rhus dec re as ing the
ve locity in each suppl y pipe by half. The BCS Unified Guidelines limit velocities in a main to 12ft /sec under
fire flow conditions . "The maximum ve locity may be increased on a case by case bas is .
The first scenario was "Ultimate Fire Flow" and analyzed the maximum fire flow that could be harnessed
from the existing line. Under TCEQ rule 290.46 (r) a minimum pressure of 20 p s i is required during fire flow
conditions. This requirement is also adhered to by the BCS Unified Guidelines. It was determined that a
maximum fire flow of 2,280 gpm could be pulled from FH (E-151) and maintain 20psi in th e distribution
system. This fire flow scenario also took into account the peak res idential demand of 17.8gp m an d the fire
sprinkler demand of 180 gpm.
The second scenario analyzed was the development as a single unit with Il.Q fire walls . The proposed
apartments are a 28,861 SF Type V-B construction developme nt. Under the International Building Code
(IBC) a Type V -B construction area between 26,301SF-29,300SF requires 4,500gpm of fire protection. Since
this development will include fire protection sprinklers the required fire fl o w can be reduced by 50% to
2,250gpm. Under a fire flow analysis of 2,250gpm, including residential and fire sprinkler demand, a
minimum pressure of 22psi was maintained at FH (E-151) and the proposed Sterling Heights development.
The third scenario analyzed was the development as a "double" unit with Qfil'. fire wall. As previously stated
th e proposed a partments are a 28,861 SF Type V-B construction development. Under the International
Building Code (IB C) a Type V-B construction area between 15 ,601SF-18,000 SF reguires 3,SO Ogp m of fire
protection. Since this develo pment will include fire protection spri nklers the required fire flow can be reduced
b y 50 % to 1,750gpm. Under a fire flow analysis of 1,750 gpm, including residentia l and fire sprinkler demand,
a minimum pressure of 49 psi was maintained at FH(E-151 ) and the proposed Sterling Heights development.
To su mmarize, the analysis proves that if the building is constructed as proposed with 28,861SF, Type V-B
construction, l 7.8pgm maximum residential demand, and 180gpm fire sprinkler demand that no fire wall will
be required to meet fire fl ow regulations. Under these conditions 2,250 gpm of fire flow will be required
which would leave a pressure of 22psi in the distributio n system. U nder this flow scenario the velo city in the
existing 6" main would b e 13.89ft/sec w hich is l.89ft/sec above the 12ft/sec limit. A discussion would be
required with the City to see if this velocity would be accepted.
If a fire wall is considered and 1,7 50gpm is u sed a pressure of 49gpm would be left in the distribution system .
Under this flow scenario the velocity in the existing main would be 11.05 ft/sec.

GENERAL LOCATION AND DESCRIPTION
Scope of Drainage Plan
The purpose of this drainage letter is to analyze the hydrological effects of site developmen t for Sterling
Heights .
This project is located on 218 Sterling Street within the Wolf Pen Creek Watershed . This drainage study
analyzes flows from the drainage area immediately surrounding the proposed development.
Description of Property
The site of the proposed Sterling Heights is currently undeveloped grass land with a few trees . The site
will be developed into approximately 1 acre of medium density residential housing . The surrounding
drainage areas are comprised of approximately 17 acres of single fam i ly and multi-family res idential
housing .
DRAINAGE DESIGN CRITERIA
Hydrologic Criteria
The following design criterion was used :
1. The rational method was used for determining rainfall storm events and runoff.
2. The equat ions for calculating rainfall intens ities were taken from BCS Unified Stormwater Design
Guidelines : Table C-1.
3. Runoff coefficients were taken from BCS Unified Stormwater Design Guidelines: Tabl es C-1 & 2.
Existing Drainage Characteristics
There ar e no existing storm drainage features on the proposed site or along Sterling Street. A single
outfall, consisting of a 20' inlet in sump and 4 grate inlets located at the north eastern end of Richard
Street, receives all existing flows from the site.
Proposed Drainage Characteristics
The proposed site will consist of one building comprising 24 units and a total area of 28,86 1 ft2
• The site
will also include 52 parking spaces and 1,028 ft2 of parking islands . All storm water will be carried above
ground by overland flow throughout the parking lot and will be conveyed into Sterling Street. The water
will flow northeast down Sterling Street for approximately 430' until the intersection with Crest Street . It
will then flow northwest along Crest Street for approximately 250' until its intersection with Richard
Street . It then flows approximately 90' northeast before it enters the existing grate and curb inlets at the
end of Richard Street . These inlets will receive flows undetained. A picture of the existing inlet structure
is attached in Exhibit 4.
Drainage System Analysis
The total area contributing to the flows at the outfall consist of two drainage areas , DA -1 and DA -2.
Exhibit 1 shows the overall drainage map .
DA -1 is approximately 15.64 acres and was analyzed using pavement, grass and residential areas . The
proposed site is located within DA -1. For pre -developed conditions, the proposed site was analyzed as
grass , and the overall drainage area had a weighted runoff coefficient of C=0.75. For post -developed
conditions, the proposed site was analyzed as pavement and grass areas, and the overall drainage area
had a we ighted runoff coefficient of C=0 .78.
DA -2 is approximately 2.09 acres and was analyzed using pavement and residential areas . It was
assumed that due to a valley gutter at the intersection of Manuel and Crest Streets that approximately
half of the flow from DA -2 would contribute to the total flow at the outfall point. For both pre and post -
developed cond itions, the overall drainage area had a weighted runoff coefficient of C=0 .77 . Exhibit 2
shows the rational method calculations . Flow differences and percentage calculations for each storm
event can be found in Exhibit 3.
A capac ity analys is was done for the existing 20 ' sump inlet and the four existing grate inlets . Equation 1
was used to determine the capacity of the sump inlet.
Q = 3.0Ly 1 ·5 [Equation 1]
The depth from the gutter to the top of the inlet was measured in the field and was found to be 1411
•
The total capacity of the inlet was determined to be 75.61 cfs . This calculated capacity was r educed by
ten percent per BCS guidelines to yield an effective capacity of 68 .05 cfs .
A capacity analys is was also done for the four existing grate inlets . Equation 2 was used to determine
the capacity for each grate inlet.
Q = 4.8 2 A9 y 0 ·5 [Equation 2]
The same depth of water on the inlet was approximated to be 12 11
• Each grate inlet had 60 clear
openings, and the size of each clear opening was measured to be 7 .25 11 x 1.37511
• The total capacity of
the four inlets was determi ned to be 80 .35 cfs . This calculated capacity was reduced by twenty five
percent per BCS guidelines to yield an effective capacity of 60 .26 cfs for all four inlets .
Inlet capacity calculations can be found in Exhibit 4 . Table 1 shows the existing capacity for the sump
and grate inlets compared to the anticipated flows for each storm event .

100 Year 100.10 103 .77 128.31 24 .54
Note : The above table summarizes flows based on the equation (DA -1) +(DA-2)/2 . This is to account for
the bypass flow of DA -2 as discussed above .
From COCS GIS information an existing 42" pipe at a slope of 1.07% was found to convey flow from the
analyzed inlets . Using manning's full flow analysis the pipe was found to have a capacity of 104 .07cfs
with a velocity of 10 .82 ft/sec. This full flow capacity is just above the estimated developed 100 year
flow of 103 .77cfs anticipated to be received by the inlets . The existing 42 " pipe has a flowline of 272 .67 '.
Under full flow conditions the headwater of the pipe would be at 276 .17 '. The elevation of the grate
inlets is located at 278.5'. This allows adequate room for the grate inlets to receive flow without having
tailwater effects from the existing 42" pipe. The existing 42 " pipe calculations and COCS GIS information
are attached in Exhibit 5.
CONCLUSIONS
From Table 1 it can be seen that the inlets will have sufficient capacity to receive post-developed flows
from the Sterling Heights development. For the post -development analysis, the inlets will have an excess
capacity during the 100 year storm event of 24 .5 cfs .

11 . Sh .5 -The proposed 4-inch waterline must be looped back to the 6-inch main rather than
dead-ended as shown .
12 . Sh .5 -Where the joint of 6-inch main is being replaced , please add a valve on the 6-inch
and specify the proposed fittings between the C-900 and AC pipe . Also , it should be noted
that additional portions of the curb & gutter and driveway will need to be removed/replaced
with the replacement of that joint of pipe .
13 . Sh .5 -The proposed 4-inch water main is required to be at least 15-ft away from the
building.
14 . Sh .5 -Show and label the proposed PUE along the front of the property on this sheet.
15 . Sh .5 -Please locate the isolation valve and meters at the edge of the PUE such that the fire
line or service line is private beyond the valve/meter.
16 . Sh .5 -The waterline should have a 4 '-5 ' bury depth . It looks like this depth requ irement is
not being met throughout the length of the pipe .
17 . Sh.6 -It looks like there should also be silt fence on portions of the eastern and southern
sides of the property based on the existing contours .
18 . Sh . 7 -FYI. .. Public works is reviewing the Traffic Control Plan , so additional comments may
be forwarded shortly .
19 . Fire Flow Report -Per the Water Department , the velocities exceeding 12 fps will not be
permitted . It appears that a fire wall will need to be utilized for this development.
20 . Fire Flow Report -The report should include the WaterCad input and output data showing
assumptions , velocities , flow , pressures , etc. within the system .
21 . San itary Sewer Report -The fixture un it method is the more conservative means to
calculate the sewer demands for the development. The "Land Use Determination " method
is meant to help estimate the demands when a project is in preliminary stages and doesn 't
necessarily know exactly what full build-out will look like.

Sterling Heights Revised Landscape Plan P&DS Project Number 15-00900019
Mr. Schubert,
I've addressed the comments to the Landscape Plan, listed on the memo sent from you on
Lrt 1 rLu·1 ::>. 1 nave oniy addressed the Landscape plan comments. Mr. Sam Vernon, P .E. has
addressed the other comments in a separate submittal. The following changes, have been
made to the site plan to address your comments. Please note that the overalt plan has
cnanged to accommodate other site plan requirements. our response to the
landscaping/Streetscaping/Buffering section are listed below in order of your comments.
1-) T he width of the driveways and visibility triangles have been removed from the linear feet of
streetscape frontage. The linear footage of the areas as they pass through the proposed right
of way is shown on the landscape plan L 1 . The calculation is shown on the landscape key
notes
2} The 10; buffer areas on each side of the property have been removed from the site area, and
the area point calculation.
3) Existing and proposed easements are now shown on the plans.
4} Planting used to meet buffering requirements have been removed from the landscape point
calculation. Note that some additional landscaping that exceeds the landscape buffer
requirement that is in the landscape buffer is counting in the total point calculation. However,
these points are non-critical to meet the overall point requirements.
5) Four canopy trees have been provided on each side of the property.
6) seven non-canopy trees have been provided on each side of the property
7) The shade tree requirement calculation has been revised to be half of the total required points.
Buffer area trees are not being used to meet this requirement.
8) Twenty crepe -myrtle non-canopy trees are being used to meet the street scape I right of way
requ irements. These crepe-myrtles are not other-wise being counted toward landscape
points.
9) The Boxwood shrub count has been revised and reconciled to meet the revised plan
10) The Savanna Holly shrub count has been revised and reconciled to meet the revised plan
11) The landscape legend has been revised to indicate caliper location requirements. Please
note that larger, greater than 3 .5 caliper inch trees have been substituted for the 2 .1 to 3 .4
cafi per inch trees.
12) The landscape legend has been revised to specify that the minimum 1.25" caliper for non-
canopy trees is measured on a single cane of a multi-trunk species.
13) The 6 ' privacy fence has been labeled.
14) The adjacent lot 4 and lot 61A--R have been labeled to include that they are single family.
The properties to the south have been labeled multi famil-y .

RE : Easements , final plat , approved site plan , order?
Matt,
For order of approvals, the final plat needs to be recorded at courthouse first, then site plan can be approved/development
permit issued, and then building permits can be issued . If a blanket easement is needed by electric it is dedicated prior to site
plan approval.
Electric transformers need to be located within PU Es so additional easement would be necessary if it would be located where a
PUE is not already existing or proposed with the plat . The typical site plan process is that a blanket easement is dedicated prior
to site plan approval as the electric layout may change in the field and CSU personnel are installing the equipment. For this
project Weldon Dav is said a blanket easement was not needed as the transformer location was set, though you'd need to make
sure all of the conduit was installed in the proposed 20 -ft PUE that would be dedicated with the plat. I'll refer you to him
r egarding what implications a second transformer would have on the electric design/layout and if a blanket easement would be
needed after all.
Thanks,
Jason

Project: Sterling Heights Apartments (SP) 15-00900019
PLANNING
1. Provide a vicinity map on the site plan, sheet C1 .0 .
2. Provide the area of the site in the site plan title block .
3 . Label the side and rear setback lines as done with the front setback.
4. All required minimum parking dimensions are measured to face of curb (wall to wall). It
appears that the dimensions and arrows have the minimum dimension but are measured to
the back of curb . Please revise accordingly .
5 . The minimum number of required handicap spaces for multi-family projects is 2% of the
spaces provided. Given 52 spaces provided , only 2 handicap spaces are required (4 are
provided), w ith one needing to be a van accessible space. Revise the ADA Parking
Requirement calculation accordingly.
6 . As the islands on the inside of the drive aisle where it bends to go along the rear serves as
the end island for both the rear and side parking rows , they must be at least 360 square feet
in area each (2x180 sq . ft.). Please revise .
7 . Revise the Parking Island Requirement on the site plan to state there are 38 interior spaces
(28 rear row+5 side row+5 side row). As such, an additional 456 square feet of island area is
to be provided (38/15x180=456). This can be incorporated into end island areas but only the
port ions of end islands that exceed their minimum requirement (180 or 360 square feet) can
count toward meeting the interior island requirement.
8. Please verify the Sterling Street pavement width . It appears to be greater than 20 feet wide.
9 . Remove the fire lane stripe along Sterling Street as public streets are not striped as fire
lanes .
1 O. As the buildings are over 30 feet in height , an aerial access fire lane of 26 feet wide (face of
curb to face of curb) needs to be provided on the site as the existing street pavement is not
wide enough to accommodate it. It may be provided on either of the sides of the site and the
remainder of the drive aisle around the building to the other driveway is also striped as a fire
lane , though not needing to be 26-foot wide for aerial access . Also, please ensure the curb
radii on the driveways and drive aisle corners meets the turning requirements for an aerial
access fire truck.
11 . If parking lot lighting is anticipated, please show the location of light poles . Please note that
private light poles cannot be placed in PUEs.
12 . Remove the existing driveway cut from Sterling Street by replacing it with the standard 6-
inch curb .
13. Label the 6-foot privacy fence along the side lots lines as well .
14. Label the zoning of the subject property and adjacent properties .
15. The layout of the interior of the units is not necessary to be depicted on the site plan .
16. Label the proposed buildings so that the number and type multi-family units that are located
in each is clear.
17 . More clearly distinguish the lines that show the building eaves going into the front setback.
Please note that the ordinance allows up to six-foot extension into front setbacks for covered
porches that are open on three sides, or balconies or decks located more than 8 feet from
the ground . Provide a note or description on the site plan stating how the extension into the
front setback is allowed .
18 . Interior clearance, inside the dumpster enclosure , must be at least 12 feet by 24 feet for two
dumpsters. It appears the dimensions are measures to the back of curb and include the
enclosure . Please revise.
19. Label or provide a detail for the specification for the dumpster enclosure .
20. Prov ide a general note on the site plan that states the following: Exterior build ing and site
lighting will meet the standards of Section 12-7 .11 of the Unified Development
Ordinance . The light source shall not project below an opaque housing and no fixture shall
directly project light horizontally . Fixtures will be mounted in such a manner that the
projected cone of light does not cross any property line .
21 . Please note that fee in lieu of parkland dedication of $1 ,636 per multi-family unit will be
requ ired prior to the issuance of building permits . For the proposed development , $39 ,264
(24 units x $1 ,636) in total will be due .
22 . Please note that any changes made to the plans that have not been requested by the City of
College Station must be explained in your next transmittal letter and "bubbled " on your
plans .

LANDSCAPING/STREETSCAPING/BUFFER
1. The width of the proposed driveway openings , as measured at the new property line , and
sight vis ibility triangles may be subtracted from the linear feet of streetscape frontage on the
landscape plan . Revise the calculations accordingly .
2 . Remove 10-foot buffer areas on each side of the site from the square feet used for the site
area and site area point calculation .
3. Illustrate the location of existing and proposed easements and ut i lities on the landscape plan
so potential conflict can be identified .
4 . Plantings used to meet buffer requirements do not receive landscape points or count toward
the streetscape plantings or canopy tree points. Move the buffer plantings to be a separate
row in the legend or provide a separate table and revise the calculations.
5 . As one canopy tree is required for every 25 linear feet of buffer, four canopy trees are
requ ired to be planted w ithin the 10-foot buffer yard on each side of the property .
6 . As one non-canopy tree is required for every 15 linear feet of buffer, seven non-canopy
trees are requ ired to be planted within the 10-foot buffer yard on each side of the property . If
des ired, the buffer yard non-canopy trees may be substituted with minimum five-gallon
shrubs that are three feet in height with one shrub per every three linear feet of buffer yard
length.
7. Rev ise the Shade Tree Requ irement calculation to be half of the total required po ints , not
half of the site area points. Please note that it appears the proposed plantings will need to
be revised as the buffer yard canopy trees cannot be used to meet this requirement.
8 . The amount of crepe myrtles counted for points is the total number proposed (streetscape
and general landscape) but not those used for buffer plantings . The current plans reflects 57
crepe myrtles that are not part of the buffe r yard . Stated differently , plantings used to meet
street scape planting requirements also are counted toward the total landscape po ints .
9. Only 83 Boxwood shrubs were counted on the plan though 100 is reflected in the legend .
Please reconcile.
10 . There were 27 Savannah Holly shrubs counted on the plan but only 25 were reflect in the
legend . Please reconcile.
11 . Rev ise the landscape legend to specify that to receive 150 point credit , the canopy tree
caliper, as measured 12 inches above grade , is between 2 .1 inches and 3.4 inches .
12. Rev ise the landscape legend to specify that the minimum 1.25-inch caliper for non-canopy
trees is measured on a single cane of multi-trunk species (crepe myrtles , etc).
13 . Label the 6-foot privacy fence along the side lots lines as wel l.
14 . Label the adjacent Lot 4 and Lot 61A-R as single-family and the properties to the south as
mu lti-family .
15 . Update the ownership of adjacent Lot 4 to the west to be Trey Adam Clark .
16 . Prov ide a general note on the landscape plan that 100% coverage of groundcover,
decorative pav ing , decorative rock (not loose), or a perennial grass is required in park ing lot
islands , swales and drainage areas , the parking lot setback , rights-of-way, and adjacent
property disturbed during construction .
17 . Revise Note 3 on the landscape plan to include the irrigation system must be protected by a
Pressure Vacuum Breaker, a Reduced Pressure Principle Back Flow Device , or a Double-
Check Back Flow Device , and installed as per City Ordinance 2394 and all BackFlow
dev ices must be installed and tested upon installation as per City Ordinance 2394 .

ENGINEERING COMMENTS NO. 1
1. Based on the scope of the project , it looks like an engineer will be needed . The water
service , as shown , is deficient and public mains will need to be extended . There are a
couple of different ways that water service can be provided , but all options will involve open
cutting the street multiple times and installing public water lines to provide domestic and fire
lines (serving each building 's sprinkler system).
2. Please provide a drainage letter from the engineer. Based on t he size of the property , this
project is eligible to request exemption from detent ion requirements .
3. Please provide a plan and profile drawing and Engineer's cost estimate for the public water
main and street repair.
4 . A traffic control plan will be needed for the street closures while connecting to the waterl ine
on the north side of Sterling and repairing the street.
5. Please submit a fire flow report indicating the necessary fire flow demands for the site per
the International Fire Code . Also, a copy of the actual fire flow test from the City and an
analysis of the available fire flow needs to be included .
6 . C1 .0 -It appears that the buildings are proposed to be sprinkled . If this is the case , a fire

RE: Revised Sterling Heights Fire Flow Analysis
Dear Erika,
I 722 Broadmoor
Suite 210
Bryan, Texas 77802
Tex. Reg. No. F-678
As requested the fire flow capacity from the existing City of College Station 6" .r\C waterline on the north
side of Sterling Street to the proposed Sterling Heights development has been analyzed. 111e subject tract is
located on 218 Sterling Street in College Station approximately two blocks south of Holleman on the cast side
of Texas A venue.
A fire flow test was completed by the City of College Station on a fire hrdrnnt located adjacent the property
at 211 Sterling Street. This fire hydrant is known :ts Fl-I (E-151) under the City of College Station
nomenclature. Fire Hydrant (E-012) was also analyzed during this flow test for static and residual pressures
while FH (E-151) was flowed. The fire hydrant flow test is summarized in Table 1 below as well as attached
for your reference.
Table 1: Fire Hydrant Flow Test
FH (E-151) FH (E-012)
Flow (gpm) 1,455 NA
Pilot reading (psi) 70 NA
Static pressure (psi) NA 100
Residual pressure {psi) NA 94
The existing City of College St:ttion waterline was modeled in Bentler WaterCad V8i to determine the
available amount of fire flow to the proposed development. A schematic layout of the model and the
\VaterCAD input and output data is attached for your reference. 111c first step in the modeling process was to
calibrate the model to accurately represent the flows and pressures determined during the fire flow test. First
the model was set up to ha\•e a static pressure in the system of 100 psi as determined in the fire flow test . 111e
npproximate elevation of the existing line at cl1is location is 300'. A pressure head of 531' was assigned to the
reservoir, "R-1 ", sen·ing our model. This difference in pressure head is 231' or exactly 1 OOpsi. A reservoir was
used to recreate the static pressure found in FH (E-112) simplifying the model to avoid recreating the system
upstream of our area of conccm. ll-1 represents pressures served by the City of College Station water system .
The second calibration was done was to ensure that FH-(E-151) was left with a pressure of 70psi when
flowing at 1,45Sgpm . This was completed by assigning a calculated length to P-1, tl1e pipe connecting "R-1"
and FH-(E-151). This calculated length created the head loss required to decrease the pressure in FTI-(E-151)
to 70 psi when flowing at 1,455gpm. 111is length, although arbitrary in itself, represents the headloss

1) The actual velocities were determined by taki ng the velocity in P-1 and dividing It by two. Currently the Bleyl & Associates model only feeds FH(E-151) from one d i rection . This assumption was made knowing
that the actual distribution system feeds FH(E-151) from both directi ons creating a looping system. The flow was assumed to be fed evenly from both side of the distribution system in fire flow conditions thus
decreasing the velocity in each supply pipe by half. The velocities In the existing City of College Station System(P·l) meet the BCS Unified Guidelines vel ocity limit of 12ft/sec under fire flow condillons.
Demand talculatlons:
• Residential demand was calculated to be 108gpm using the fixture unit method outlined in the ecs unified guidelines . See sanita ry sewer report for detailed calculations.
• The fire sprinkler demand was calculated to be 180gpm bv a licensed fire system designer.
• A fire flow demand of l, 750gpm was used for a Type V-B construction unit with a single fire wall .
