Phase 108 is a townhouse residential development, which will include the construction of utility and roadway infrastructure. Location: Description: • Area: • Proposed Land Use: • #of Lots: • Existing Land Use: • Land Description: Primary Drainage Facility: Flood Hazard Information: FEMAFIRM: Floodplain: Phase 108 is located northeast of Phase 105 of the Barracks II Development. The Barracks II Subdivision is a 108-acre development located midway between Rock Prairie Road and Cain Road in south College Station. It is bounded on the west by Holleman Drive South and on the east by Old Wellborn Road. 6.909 Acres Townhouse Residential 63 lots Vacant The terrain slopes generally towards the north. Tributary B.3 of Bee Creek #48041C0305F, Dated April 2, 2014 None of this phase of the development lies within the floodplain. ! HYDROLOGIC CHARACTERISTICS The existing site is cleared. The elevations range from 305 to 302, sloping generally in a northerly direction. The majority of the runoff will be directed to the roadways and the proposed storm sewer system and will discharge into Old Wellborn Road roadside ditch. The stormwater detention facility drainage report prepared by Kimley-Horn will be revised to evaluate the proposed drainage. The remaining runoff will be directed to the roadways and the proposed storm sewer system and will discharge into the existing detention facilities on Lot 1, Block 28 Phase 300 of The Barracks II Subdivision. Ultimately, this runoff flows into Tributary B.3 of Bee Creek. GENERAL STORMWATER PLAN The drainage plan for this development will involve the installation of storm sewer pipes and inlets, which will collect and convey a portion of the runoff into the existing storm sewer system and then to the existing detention pond. This development will also involve the use of the existing drainage ditch along Old Wellborn Road which will collect and convey the runoff downstream. The runoff that is collected by the existing detention ponds and the Old Wellborn Road ditch will be discharged into tributary B.3 of Bee Creek. The detention pond analysis and design for this phase is covered under the drainage report titled, "The Barracks Detention Facility Design City of College Station, Texas, Dated July 2012" prepared by Kimley-Horn and as modified in September 2013 and by a revised design being prepared by Kimley-Horn. This revised report will take into account the development of the adjacent tract to the north which has been acquired and will become part of the Barracks. COORDINATION & STORMW ATER PERMITTING This project has a Notice oflntent filed with the Texas Commission for Environmental Quality. No other permits are anticipated for this project. DRAINAGE DESIGN General Information: Street Design: Tc Methodology: Tc Minimum: Design Storm Event: Pipe Materials: Manning's n Values: Runoff Coefficients: Design Constraints: Stormwater runoff from Phase 108 of the subdivision will be collected by a storm sewer system. The location of the drainage areas for evaluation of the gutter depth check, inlet sizing, pipe evaluation and channel sizing are shown on Exhibit A & B. Refer to Exhibit B for the locations of the inlets and storm sewer pipes. Armored Avenue: Standard Cross-Section (3% cross-slope, 27' B-B Residential Roadway) Lay down and standard curb and gutter on residential streets Tang Cake Drive: Collector Street Cross-Section (3% cross-slope, 38' B-B) Standard Curb and gutter Concrete Pavement Standard recessed curb inlets (5', 10', & 15' in length) TR55 10 Minutes 10 year design storm & 100 year analysis for residential and collector streets & storm sewer Class III RCP, Profile Gasket in accordance with ASTM C443, ASTM C76 and Corrugated HDPE Storm Sewer Pipe with smooth interior 0.013 for pipes 0.018 for Streets 0.75 for developed lots 0.45 for undeveloped land Max. water depth in gutter: 4.5" or 0.375' for the 10 year design storin for residential and collector streets Min. pipe flow velocity: 2.5 fps Max. pipe flow velocity: 15 fps 100-yr storm runoff maintained within the ROW (3" above curb) 25% reduction of cross-sectional area of pipes less than 24" in diameter Min. 1' freeboard for the 10 year design storm depth of flow Design Software: Design Results: Detention Analysis: Applicable Exhibits: CONCLUSION Excel Spreadsheets, Hydraflow Express Extension for AutoCAD Civil 3D 2013, & Autodesk Civil 3D Storm Sewer Analysis. The software was used to compute pipe capacities, flow rates and velocities, compute hydraulic grade line elevations, headwater elevations, gutter depth & inlet sizing. The requirement for a 25% reduction in cross sectional area of pipes 24" in diameter or less 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. runoff from the Barracks II Subdivision was previously studied and detention ponds were designed for the entire development including this phase. See the drainage report titled, "The Barracks Detention Facility Design City of College Station, Texas, Dated July 2012" and as modified in September 2013 and by a revised design being prepared by Kimley-Horn. Sheet 05, ''Proposed Condition Drainage Area Map'', from the Kimley-Horn September 2013 ''Modicfications to The Barracks Detention Facility" design 'shows Drainage Area Cl, 16.82 acres of the project area discharging into the Old Wellbron Road right of way. With the final design of Phase 107 and 108 the computed area discharging into the Old Wellborn Road right of way is 16.66 acres. Since this is less than the area shown by Kimley-Horn the existing detention facilities for The Barracks are adequate for this phase of the subdivision and no additional pond construction or modifications are necessary.

Channel No. 1 parallel to Old Wellborn Road will have 2 different cross sections. From station 0+00 to station 7+50 the proposed channel will have a trapezoidal cross section with a 6 foot bottom width and 4 to 1 side slopes. From station 7+50 to station 12+00 the proposed channel will have a "V" cross section with 4 to 1 side slopes. Channel reports are attached to this letter evaluating the channel at the two different cross sections. The channel reports show that in the first cross section there is a minimum of 0 .14' freeboard in the 100-yr storm event and in the second cross section there is a minimum of 0.05 ' freeboard in the 100-yr storm event.

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 dig itized. 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. Part 1 -Executive Summary Report Part 2 -Project Administration Part 3 -Project Characteristics Part 4 -Drainage Concept and Design Parameters Part 5 -Plans and Specifications Part 6 -Conclusions and Attestation 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 Effective February 2007 Page 1of26 APPENDIX. D: TECH . DESIGN SUMMARY As Revised August 2012 SECTION IX APPENDIX D -TECHNICAL DESIGN SUMMARY 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 culverts; 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. Coordination 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 elements 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 ___ -page specifications document dated comprise the drainage report for this project."

GENERAL INFORMATION The Barracks II Subdivision is a 108-acre development in the area generally bounded by Wellborn Road on the east, Holleman Drive South on the west, Cain Road to the north and Rock Prairie Road to the south. It is zoned PDD and is comprised of a mixture of residential and commercial land uses as shown on Exhibit A. There are 425 residential lots planned for the site and 25.3 acres of commercial property. The area surrounding the site is generally undeveloped, with the exception of three residential developments adjoining the tract on the south. The majority of the area between Cain Road and Rock Prairie Road is described as General Suburban in the City's Comprehensive Plan, which implies that it is likely to develop in a similar manner as The Barracks II Subdivision Phases 100-106, 200 and 300 have been completed or are under construction. Phases 108 1s unchanged from the Preliminary Plat and will add 63 new lots. Sewer service to the area is provided by 18" and 12" lines running along Old Wellborn Road and along the south property line of The Barracks II Subdivision. These lines will be the primary outfall for this development, but they are also intended to serve other adjoining tracts in the same sewer basin. These adjoining areas are identified as: CSISD Tract-23.50 acres Mayo Tract -24.99 acres Turner Tract (partial)-15.08 acres Barger Tract (partial)-18.06 acres All four of these tracts are presently zoned R. None of these tracts affect this portion of the Sewer System. Design Criteria: Primary Sewer Outfall: Domestic Demand: Avg. Pop Density: Average Flow: Peaking Factor: Commercial Demand: Avg.

Phase 108 is a townhouse residential development, which will include the construction of utility and roadway infrastructure. Location: Description: • Area: • Proposed Land Use: • #of Lots: • Existing Land Use: • Land Description: Primary Drainage Facility: Flood Hazard Information: FEMAFIRM: Floodplain: Phase 108 is located northeast of Phase 105 of the Barracks II Development. The Barracks II Subdivision is a 108-acre development located midway between Rock Prairie Road and Cain Road in south College Station. It is bounded on the west by Holleman Drive South and on the east by Old Well born Road. 6.909 Acres Townhouse Residential 63 lots Vacant The terrain slopes generally towards the north. Tributary B.3 of Bee Creek #48041C0305F, Dated April 2, 2014 None of this phase of the development lies within the floodplain. ! HYDROLOGIC CHARACTERISTICS The existing site is cleared. The elevations range from 305 to 302, sloping generally in a northerly direction. The majority of the runoff will be directed to the roadways and the proposed storm sewer system and will discharge into Old Wellborn Road roadside ditch. The stormwater detention facility drainage report prepared by Kimley-Hom will be revised to evaluate the proposed drainage. The remaining runoff will be directed to the roadways and the proposed storm sewer system and will discharge into the existing detention facilities on Lot 1, Block 28 Phase 300 of The Barracks II Subdivision. Ultimately, this runoff flows into Tributary B .3 of Bee Creek. GENERAL STORMWATER PLAN The drainage plan for this development will involve the installation of storm sewer pipes and inlets, which will collect and convey a portion of the runoff into the existing storm sewer system and then to the existing detention pond. This development will also involve the use of the existing drainage ditch along Old W ellbom Road which will collect and convey the runoff downstream. The runoff that is collected by the existing detention ponds and the Old Wellborn Road ditch will be discharged into tributary B.3 of Bee Creek. The detention pond analysis and design for this phase is covered under the drainage report titled, "The Barracks Detention Facility Design City of College Station, Texas, Dated July 2012" prepared by Kimley-Hom and as modified in September 2013 and by a revised design being prepared by Kimley-Hom. This revised report will take into account the development of the adjacent tract to the north which has been acquired and will become part of the Barracks. COORDINATION & STORMWATER PERMITTING This project has a Notice of Intent filed with the Texas Commission for Environmental Quality. No other permits are anticipated for this project. DRAINAGE DESIGN General Information: Street Design: Tc Methodology: Tc Minimum: Design Storm Event: Pipe Materials: Manning's n Values: Runoff Coefficients: Design Constraints: Stormwater runoff from Phase 108 of the subdivision will be collected by a storm sewer system. The location of the drainage areas for evaluation of the gutter depth check, inlet sizing, pipe evaluation and channel sizing are shown on Exhibit A & B. Refer to Exhibit B for the locations of the inlets and storm sewer pipes. Armored Avenue: Standard Cross-Section (3% cross-slope, 27' B-B Residential Roadway) Lay down and standard curb and gutter on residential streets Tang Cake Drive: Collector Street Cross-Section (3% cross-slope, 38' B-B) Standard Curb and gutter Concrete Pavement Standard recessed curb inlets (5 ', 10', & 15' in length) TR55 10 Minutes 10 year design storm & 100 year analysis for residential and collector streets & storm sewer Class III RCP, Profile Gasket in accordance with ASTM C443, ASTM C76 and Corrugated HDPE Storm Sewer Pipe with smooth interior 0.013 for pipes 0.018 for Streets 0.75 for developed lots 0.45 for undeveloped land Max. water depth in gutter: 4.5" or 0.375' for the 10 year design storin for residential and collector streets Min. pipe flow velocity: 2.5 fps Max. pipe flow velocity: 15 fps 100-yr storm runoff maintained within the ROW (3" above curb) 25% reduction of cross-sectional area of pipes less than 24" in diameter Min. l' freeboard for the 10 year design storm depth of flow Design Software: Design Results: Detention Analysis: Applicable Exhibits: CONCLUSION Excel Spreadsheets, Hydraflow Express Extension for AutoCAD Civil 3D 2013, & Autodesk Civil 3D Storm Sewer Analysis. The software was used to compute pipe capacities, flow rates and velocities, compute hydraulic grade line elevations, headwater elevations, gutter depth & inlet sizing. The requirement for a 25% reduction in cross sectional area of pipes 24" in diameter or less 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. runoff from the Barracks II Subdivision was previously studied and detention ponds were designed for the entire development including this phase. See the drainage report titled, "The Barracks Detention Facility Design City of College Station, Texas, Dated July 2012" and as modified in September 2013 and by a revised design being prepared by Kimley-Horn. Sheet 05, "Proposed Condition Drainage Area Map", from the Kimley-Horn September 2013 "Modicfications to The Barracks Detention Facility'' design -shows Drainage Area Cl, 16.82 acres of the project area discharging into the Old Wellbron Road right of way. With the final design of Phase 107 and 108 the computed area discharging into the Old Wellborn Road right of way is 16.66 acres. Since this is less than the area shown by Kimley-Horn the existing detention facilities for The Barracks are adequate for this phase of the subdivision and no additional pond construction or modifications are necessary.

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. Part 1 -Executive Summary Report Part 2 -Project Administration Part 3 -Project Characteristics Part 4 -Drainage Concept and Design Parameters Part 5 -Plans and Specifications Part 6 -Conclusions and Attestation 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 Effective February 2007 Page 1 of26 APPENDIX. D: TECH. DESIGN SUMMARY As Revised August 2012 SECTION IX APPENDIX D -TECHNICAL DESIGN SUMMARY 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 culverts; 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. Coordination 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 elements 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 ___ -page specifications document dated ____ comprise the drainage report for this project."

DESIGN SUMMARY As Revised August 2012 Water System Report for The Barracks II Subdivision Phase 108 College Station, Texas June 2014 Prepared Bv: TBPE Firm Registration No. 12327 2730 Longmire, Suite A College Station, Texas 77845 979.764.3900 F-123.27 SCHULTZ ENGINEERtNGt LL,C,. General Information Location: General Note: Land Use: Phase 108 is located northeast of Phase 105 of the Barracks II Development. The Barracks II Subdivision is a 108-acre development located midway between Rock Prairie Road and Cain Road in south College Station. It is bounded on the west by Holleman Drive South and on the east by Old Wellborn Road. The water lines to serve these 63 residential lots will be a 6" line along Armored Avenue, 6" & 8" line along Old Wellborn Road and an 8" line along Tang Cake Drive. These lines will create a loop in the system. These lines will connect to existing waterlines constructed in previous phases. Single family residential Design Criteria/ Analysis Primary Water Supply: Existing 8" water line along Tang Cake Drive and existing 6" waterline along Armored A venue.

This report provides the results of the water system analysis under the fire flow and domestic demand requirements, (1,552 gpm) which produced the lowest pressure in the system. Conclusion Summary of Calculations Pressure 70.1 Domestic Demand Min. Velocity Max 1.55 Pressure 55.6 Domestic Demand & Fire Min. Hydrant 5 Velocity Max 5.43 Pressure 54.1 Domestic Demand & Fire Min. Hydrant 6 Velocity Max 6.28 The minimum pressure (54.1 psi) for this system occurs when a Fire Flow demand is set at Fire Hydrant Number 6. The Max Velocity for this system occurs at the same demand when the velocity in Pipe P-87 has a velocity of 6.28 fps. All of these pressures exceeds the 20 psi and 35 psi minimum pressure requirements, respectively. The maximum pipe velocities are less than 12 fps. The proposed 8" and 6" water lines meet or exceed all of the design criteria for the City of College Station and the Wellborn Special Utility District. It will provide adequate water pressure, flowrate and velocity for both domestic and fire flow demands.

Civil Engineer City of College Station 1101 Texas Avenue College Station, TX 77840 Re: The Barracks II Subdivision-Ph 108-14-00900151 Dear Ms. Singh: Office: 979.764.3900 Fax: 979.764.3910 Attached are test results for the lime stabilized subgrade for the streets and alley in Phase 108. The lime stabilized subgrade did not meet the pH requirement of 12.4 as shown on report 0002. The Plasticity Index, PI, of all of the samples was 18 or less. Report 0003 shows the thickness of the lime stabilized subgrade to be more than 2" greater than the required thickness. The additional thickness reduced the amount of lime in the soil thereby also reducing the pH. Based on the thickness and PI of the lime stabilized subgrade and since the reinforced concrete pavement is being used for these streets and alley, it is my recommendation to accept the lime stabilized subgrade.
