ENGINEERING COMMENTS NO. 2
4. Please Check Drainage Report . Pipe 560 is having flow even though the plans show that
the pipe is capped at the end . Please adjust slope of pipe 510 , so that it has a minimum
velocity of 2 .5 feet per second .
5. We considered your proposed waterline W-5 and W-8 going underneath the storm sewer

change the sections that do not meet a 4 foot depth to ductile iron pipe with cement
stabilized sand backfill.

ENGINEERING COMMENTS NO. 1
1. Please fix Drainage Report. On Append ix C1 , Pipes 511 , 512 , and 570 show 0 flow,
velocity , etc. On Appendix D page 24 , some of the design flow velocities are not matching
the provided spreadsheets .
2 . Check Storm Drain Pipe 570 . On Construction plan sheet 8 , p ipe 570 shows a 0.50% slope
while the same pipe in Storm Drain report shows a 1 % slope.
3. In lieu of ach ieving a minimum 4 foot depth on waterline W-8 , we would need to have the
sect ion that does not meet the minimum 4 foot depth (approximately Sta 3+80 to Sta 4+80 )
change to ductile iron pipe with cement stabilized sand backfill.
4 . Please fix Water system Report . Check if the Water System summary is congruent with
sect ion 105 due to the title summary saying section 104 . Minimum fire flow pressure
demand for FH 13 on the summary table is not match ing the spreadsheet.
5. Add the following note to Sewer plan "No sanitary sewer service will be left more than 3.5
feet deep at the point of terminus by developer's contractor."
6 . Please include the scale on the sewer profiles .
7. Due to the depth of Sewer lines S-14 and S-12 be ing greater than 6 foot , we would need an
add itional 5 foot width Public Utility easement total ing a 10 foot Public Utility easement on
property lots adjacent to sewer lines . Also we would need the Sewer lines adjusted to be
centered between behind the curb and the edge of the Public Utility easement in such a way
that there 's a 10 foot clearance to behind the curb and the outer edge of the Public Utility
easement.
8. On t he sewer line sheet 13 & 14 , the profiles indicate "see note 8" that is not provided on the
sewer plans .
9. Manhole No . 553 needs to be changed to standard drop manhole.

ENGINEERING COMMENTS NO. 1
y Please fix Drainage Report. On Appendix C1, Pipes 511 , 512 , and 570 show 0 flow ,
velocity, etc. On Appendix D page 24, some of the design flow velocities are not matching
the provided spreadsheets.
Appendix C1 is now shown without Pipes 511, 512 and 570 . These Pipes are
stubbed out for future phases of Castlegate II. The plans show that these Pipes
are capped at the end allowing zero flow. Since there is now flow in these pipes
they are not evaluated in the Drainage Report. They will be evaluated in the future
phases of Castlegate II
Page 24 of Appendix D has been updated and included in this submittal.
2 .f check Storm Drain Pipe 570 . On Construction plan sheet 8, pipe 570 shows a 0.50% slope
while the same pipe in Storm Drain report shows a 1 % slope.
Appendix C1 is updated with the slope of Pipe 570. A copy of the revised Appendix
C1 is included in this submittal.
@ In lieu of achieving a minimum 4 foot depth on waterline W-8, we would need to have the
section that does not meet the minimum 4 foot depth (approximately Sta 3+80 to Sta 4+80)
change to ductile iron pipe with cement stabilized sand backfill.
The profile of waterline W-5 and W-8 have been revised to have a minimum of 4' of
cover. Bends for vertical deflection have been used to take the waterline under the
storm sewer pipes.
/ Please fix Water system Report. Check if the Water System summary is congruent with
sect ion 105 due to the title summary saying section 104. Minimum fire flow pressure
demand for FH 13 on the summary table is not matching the spreadsheet.
The Water Report conclusion page has been updated. A copy of this page is
included in this submittal.
/.Add the following note to Sewer plan "No sanitary sewer service will be left more than 3.5
feet deep at the point of terminus by developer's contractor."
Note 10 has been added.
jl Please include the scale on the sewer profiles.
Scales have been added to the profile view on pages 13and14.
7. Due to the depth of Sewer lines S-14 and S-12 being greater than 6 foot, we would need an
addit ional 5 foot width Public Utility easement totaling a 10 foot Public Utility easement on
property lots adjacent to sewer lines. Also we would need the Sewer lines adjusted to be
centered between behind the curb and the edge of the Public Utility easement in such a way
that there's a 10 foot clearance to behind the curb and the outer edge of the Public Utility
easement.
The PUEs on the lots adjacent to the sewer lines have been increased to 10'. The
alignment of the sewer is already set by the existing sewer alignment. The sewer
alignment is the same as previous sections so the sewer line alignment has not
been adjusted. j On the sewer line sheet 13 & 14 , the profiles indicate "see note 8" that is not provided on the
sewer plans .
Note 8 has been added.
/(: Manhole No. 553 needs to be changed to standard drop manhole .

Project: CASTLEGATE II SEC 105 (FP) -14-00900175
PLANNING
1. Parkland dedication fees of $25,000 will be due upon filing of the final plat.
Noted.
2. 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. Any additional changes on these plans that the City has not been made
aware of will constitute a completely new review.
Noted.
3. Please note that you may be required to submit paid tax certificates if they are not
current prior to the filing of your plat.
Noted.
ENGINEERING COMMENTS NO. 2
4. Please Check Drainage Report. Pipe 560 is having flow even though the plans show that
the pipe is capped at the end. Please adjust slope of pipe 510, so that it has a minimum
velocity of 2 .5 feet per second .
The plans are incorrect. We are exposing Pipe 560 to allow up stream flow
into the pipe. The plans, engineer's estimate and a revised Appendix C1
are attached. Rock riprap was added to the engineer's estimate. Pipe 510
has a 4.42 fps velocity in the 10 year storm and a 4.39 fps velocity in the
100 year storm.
5. We considered your proposed waterline W-5 and W-8 going underneath the storm sewer
pipes. Due to the excessive depth, please change it back how you had it previously and
change the sections that do not meet a 4 foot depth to ductile iron pipe with cement
stabilized sand backfill.
W-8 is now ductile iron pipe. The Plans and the engineer's estimate have
been revised.

GENERAL DESCRIPTION AND LOCATION
Section 105 is the eleventh phase being constructed in the Castlegate II Subdivision. It lies on the west portion of the
subdivision, and is adjacent to Section 103. It consists of 40 residential lots, and includes an extension ofEntonbury
A venue, Kinnersley Lane and Hailes Lane. All ?! Section )_05 lies wi thin the Spring Creek Drainage Basin 1\fld will
drain into the previ ously constructed detention pond. That pond was designed to accommodate runoff from Section
105 and all assumptions associated with its design are still valid. No additional stormwater detention is being
proposed with Section 105.

12-06-1841P, Dated May 18 , 2012
None of this phase of the development lies within the floodplain .
HYDROLOGIC CHARACTERISTICS
The existing site is wooded with some cleared areas. The elevations range from 324 to 330, sloping generally in a
northeasterly direction . The runoff will be directed to the roadways and the proposed storm sewer system will
discharge into the existing storm sewer system constructed with Sections 103 & 101 and then discharges into the
existing detention facilities. Ultimately, this runoff flows into Spring Creek Tributary A2A.
GENERALSTORMWATERPLAN
The drainage plan fo r this development will involve the installation of storm sewer pipes and inlets, which will
collect and convey the runoff into the existing storm sewer system and then to the existing detention pond. The
runoff that is collected by the existing detention ponds will be discharged into Spring Creek Tributary A2A.
COORDINATION & STORMW ATER PERMITTING
This project has a Notice of Intent filed with the Texas Commission for Environmental Quality. No other permits
are anticipated for this project.

CONCLUSION
The requirement for a 25% reduction in cross sectional area of pipes less than
24" diameter is achieved by using internal pipe diameters that are less than the
standard diameter. The 24" diameter pipe areas were reduced by 25% and a
20.6" diameter pipe was used in the analysis and the 18" diameter pipe areas
were reduced by 25 % and a 15.6" diameter pipe was used in the analysis.
The data presented in the Appendices indicates the gutter depth, inlet sizing,
pipe sizes and channel sizing is in accordance with the requirements of and the
City of College Station.
The stormwater runoff from Castlegate II Subdivision was previously studied
and detention ponds were designed for the entire development including this
phase.

TECHNICAL DESIGN SUMMARY
SECTION IX
APPENDIX D -TECHNICAL DESIGN SUMMARY
The Cities of Bryan and College Station both require storm drainage design to follow these
Unified Stormwater Design Guidelines. Paragraph C2 of Section Ill (Administration) requires
submittal of a drainage report in support of the drainage plan (stormwater management plan)
proposed in connection with land development projects, both site projects and subdivisions .
That report may be submitted as a traditional prose report, complete with applicable maps,
graphs, tables and drawings, or it may take the form of a "Technical Design Summary". The
format and content for such a summary report shall be in substantial conformance with the
description in this Appendix to those Guidelines. In either format the report must answer the
questions (affirmative or negative) and provide , at minimum, the information prescribed in the
"Technical Design Summary" in this Appendix .
The Stormwater Management Technical Design Summary Report shall include several parts
as listed below . The information called for in each part must be provided as applicable. In
addition to the requirements for the Executive Summary, this Appendix includes several
pages detailing the requirements for a Technical Design Summary Report as forms to be
completed . These are provided so that they may be copied and completed or scanned and
digitized. In addition, electronic versions of the report forms may be obtained from the City.
Requirements for the means (medium) of submittal are the same as for a conventional report
as detailed in Section Ill of these Guidelines.
Note: Part 1 -Executive Summary must accompany any drainage report
required to be provided in connection with any land development project ,
regardless of the format chosen for said report.
Note: Parts 2 through 6 are to be provided via the forms provided in this
Appendix. Brief statements should be included in the forms as requested ,
but additional information should be attached as necessary.

STORMWATER MANAGEMENT TECHNICAL DESIGN SUMMARY REPORT
Part 1 -Executive Summary
This is to be a brief prose report that must address each of the seven areas listed below .
Ideally it will include one or more paragraphs about each item.
1. Name , address, and contact information of the engineer submitting the report, and
of the land owner and developer (or applicant if not the owner or developer). The
date of submittal should also be included.
2. Identification of the size and general nature of the proposed project, including any
proposed project phases. This paragraph should also include reference to
STORMWATER DESIGN GUIDELINES

applications that are in process with either City: plat(s), site plans, zoning requests,
or clearing/grading permits, as well as reference to any application numbers or
codes assigned by the City to such request.
3. The location of the project should be described. This should identify the Named
Regulatory Watershed(s) in which it is located , how the entire project area is
situated therein , whether the property straddles a watershed or basin divide , the
approximate acreage in each basin , and whether its position in the Watershed
dictates use of detention design. The approximate proportion of the property in the
city limits and within the ET J is to be identified , including whether the property
straddles city jurisdictional lines. If any portion of the property is in floodplains as
described in Flood Insurance Rate Maps published by FEMA that should be
disclosed.
4. The hydrologic characteristics of the property are to be described in broad terms:
existing land cover; how and where stormwater drains to and from neighboring
properties; ponds or wetland areas that tend to detain or store stormwater; existing
creeks , channels, and swales crossing or serving the property; all existing drainage
easements (or ROW) on the property, or on neighboring properties if they service
runoff to or from the property.
5. The general plan for managing stormwater in the entire project area must be
outlined to include the approximate size, and extent of use, of any of the following
features : storm drains coupled with streets ; detention I retention facilities ; buried
conveyance conduit independent of streets; swales or channels; bridges or cu lverts ;
outfalls to principal watercourses or their tributaries; and treatment(s) of existing
watercourses. Also, any plans for reclaiming land within floodplain areas must be
outlined.
6 . Coord ination and permitting of stormwater matters must be addressed. This is to
include any specialized coordination that has occurred or is planned with other
entities (local, state, or federal). This may include agencies such as Brazos County
government, the Brazos River Authority , the Texas A&M University System, the
Texas Department of Transportation , the Texas Commission for Environmental
Quality, the US Army Corps of Engineers, the US Environmental Protection Agency,
et al. Mention must be made of any permits, agreements, or understandings that
pertain to the project.
7. Reference is to be made to the full drainage report (or the Technical Design
Summary Report) which the executive summary represents. The principal
elemen ts of the main report (and its length), including any maps, drawings or
construction documents, should be itemized. An example statement might be:
"One -page drainage report dated one set of
construction drawings ( sheets) dated , and a

GENERAL INFORMATION
The Castlegate II Subdi vision is a 202-acre residential subdivision being developed immediately
southwest of the existing Castlegate Subdivision in College Station . The approved Preliminary Plat
shows a total of 645 lots in the whole development. Sections 200, 201, 202 , 203, 205 , 100, 101 , 103
and 104 have been completed or are under construction. Section 105 is unchanged from the
Preliminary Plat and will add 40 new lots .
The tract of land that comprises this subdivision lies across a drainage divide that cannot be crossed
using gravity lines . As a result , a lift station is being planned in a later phase of the development.
The force main from this development will empty into one of the trunk lines that serve much of the
rest of the development. On the spreadsheet shown in Exhibit C, the force main is shown as a 12 "
gra v ity line for computational purposes.
Design Criteria:
Primary Sewer Outfall: Section 105 -6" sewer line at existing terminus of Kinnersley Drive and a
6" sewer line at existing terminus of Hailes Lane both constructed with
Section 101 .

Exhibit A -Overall Sewer System Layout
Exhibit B -Section 105 Sewer System Layout
Exhibit C -Sanitary Sewer Analysis Spreadsheet
The sewer system shown in Exhibit A has been laid out using the criteria in the Bryan/College
Station Design Guidelines and TCEQ . It is analyzed assuming peak flow conditions when the
s ubdivision is fully developed . The spreadsheet in Exhibit C shows all lines depicted in Exhibit B to
be capable of carrying the flows that come to them under these conditions . This analysis will be used
as the basis for all subsequent sewer line designs in the subdivision. The system will function as
intended as long as the line sizes and slopes are equal to or greater than those shown herein . It should
be noted that any significant additional flow from off-site sources will likely exceed the capacity of
several lines , so careful study is advised of any changes to the contributing area.

General Information
Location : The Castlegate II Subdivision, Section 105 is a 8.551-acre residential
subdivision being developed immediately northwest of the existing
Castlegate II Subdivision, Section 103 in College Station. The Final Plat
shows a total of 40 lots in this section.
Gen eral Note: An analysis was conducted on the entire Castlegate II water system to
ensure its ability to serve all lots under fully developed conditions. This
analysis was conducted with water line sizes of 8" or less to demonstrate
that larger size lines are not necessary even though they may be required
by the City for future development in the area . Ref er to the report by
Phillips Engineering titled " Water System Report For Castlegate II,
Section 200 College Station , Texas", revised April 2011.
Primary Water Supply: Castlegate water service is provided by an existing 8" line on Victoria
A venue and an 8" line that lies in an easement in Section 7 of Castlegate.
Section 200 was connected to each of these lines, and both lines will be
used to provide looping in all future phases of the development. Section
105 connects to an existing 8" waterline that was constructed with
Castlegate II Section 103 and existing 6" waterlines constructed with
Castlegate II Section 101.
Land Use : Single family residential
Design Criteria/ Analysis
Primary Water Supply: Existing 6" water line along Kimbolton Drive, an existing 6" water line
along W arkworth Lane and an existing 8" water line along Etonbury
Lane .

Future Development (Section 107)-41 Lots = 61.5 gpm
Total Domestic Demand= 475.5 gpm
The proposed 8"& 6" water lines are in accordance with the BCS Water
Design Guidelines. This report provides the results of the water system
analysis under the fire flow and domestic demand requirements , (1475.5
gpm) which produced the lowest pressure in the system .

Conclusion
Velocity Max.
As shown above the system exceeds the minimum required
pressures of 35 psi for domestic flow and 20 psi for fire flow in
both analyses. The maximum velocity of 11. 72 fps is less than the
required maximum of 12 fps.
The proposed 8" and 6" water lines meet or exceed all of the design
criteria for the City of College Station. They will provide adequate water
pressure, flowrate and velocity for both domestic and fire flow demands .

The proposed 8"& 6" water lines are in accordance with the BCS Water
Design Guidelines. This report provides the results of the water system
analysis under the fire flow and domestic demand requirements, (1475.5
gpm) which produced the lowest pressure in the system.

Conclusion
Velocity Max.
As shown above the system exceeds the minimum required
pressures of 35 psi for domestic flow and 20 psi for fire flow in
both analyses. The maximum vel ocity of 11.72 fps is less than the
required maximum of 12 fps.
The proposed 8" and 6" water lines meet or exceed all of the design
criteria for the City of College Station. They will provide adequate water
pressure, flowrate and ve locity for both domestic and fire flow demands.
