City Engineer City of College Station P.O. Box 9960 College Station, Texas 77842 Re.: Copperfield Parkway Apartments Proposed Water System Changes COCS No. 14-00900017 MBESl No. 10000265 Dear Carol, As per our conversation on Friday afternoon and to address Stephen Maldonado's concerns regarding the ve locities in the proposed water main for the above referenced project, it is my understanding that the BCS Unified Design Guidelines requires the developer to provide a water system that will be capable of meet fire flows plus the average dail y flow for the development while maintaining 20 p.s.i . in the system while keeping the velocities below 12 f.p.s. For as long as I have been working in College Station, we have always applied the fire flow to the hydrant or hydrants that produce the "worst" conditions on the system. The fire code states that if flows are below 1,750 g.p.m. the flow can be distributed by a minimum of one fire hydrant (i.e. this is how I elected to analyze the system which produced the velocity of 12.05 f.p.s.) Because the fire code states that a minimum of one hydrant can be used, this allows the engineer the flexibility to spli t the flow between more than one hydrant. Therefore, I have reanalyzed the proposed water system improvements by splitting the fire flow (i.e. 825 g.p.m. per hydrant) between junctions J-14 and J-15 (i.e. the two most remote fire hydrants.) Based on the KYPipe results, the maximum velocity will be approximately 10 . 7 f.p.s. and will occur in Pipes P-15 and P-20 (refer to the attached results.) The results show that the proposed water system improvements are in compliance with the BCS Unified Design Guidelines; therefore, I respectfully request approval of the revised waterline drawings as submitted. Please review this information at your earliest convenience and let me know when you are ready for the signed/sealed copies for your approval stamp. Let me know if you have any questions or need any additional information regarding this matter. Sincerely, f!U J. Dale Browne, Jr., P.E.

Box 9960 College Station, Texas 77842 Re.: Copperfield Parkway Apartments Proposed Water System Changes COCS No. 14-00900017 MBESI No. 10000265 Dear Carol, This letter is being sent to you to request approval of a proposed change to the water system improvements for the above referenced project. The Owner has requested that we connect to the existing 8" waterline that crosses under Crescent Pointe Parkway near the southeast comer of the site. This will be in lieu of boring Crescent Pointe Parkway at the proposed entrance to the development. Please find attached the following for your review: • • • • • Two set of the revised construction drawings for Sheets C5.1 , C5.2 and C5.3. The proposed water line changes are all on Sheet C5.1. The stations for Waterline WA-1 and WA-2 were the only elements that were impacted on Sheets C5.2 and C5.3. Figure "A" Revised Water System Model Attachment "A-1 " -Revise Water Model Summary of the Input Data Attachment "A-2" -Revised Water System Model Results Scenario 1 Attachment "A-3" -Revised Water System Model Results Scenario 2 (Refer to the design report for this project for a description of scenarios.) Based on the KYPipe results, the velocity in P-15 and P-20 will be approximately 12.05 fps when the fire hydrant a J-15 is flowing at 1,650 g.p.m. We believe this is negligible and certify that the proposed changes are in general compliance with the BCS Unified Design Guidelines. Please review this information at your earliest convenience and let me know when you are ready for the signed/sealed copies for your approval stamp. Let me know if you have any questions or need any additional information regarding this matter. Sincerely, fiLt J. Dale Browne, Jr., P.E.

This report includes the traffic impact analysis, water system analysis and drainage system analysis for the proposed project. General Location and Description The project is located on Lot 3R, Block 2 of the Crescent Pointe Phase 2 subdivision. Refer to Figure "A" for the Location Map. It is located on Crescent Pointe Parkway approximately 700 feet west of the intersection of the north intersection of Crescent Pointe Parkway and Copperfield Parkway. The entire project is located within the city limits of College Station. The development will consist of 14 acres and involve the construction of 12 3-story apartment buildings with a total of 280 units, clubhouse/leasing office with pool area and associated parking facilities. The new apartment buildings will be construction type V-B and will be equipped with a sprinkler system. The clubhouse/leasing office will not be equipped with a sprinkler system and is also type V-B construction. Traffic Impact Analysis As stated previously, the proposed development will consist of 280 units and falls under the definition of a mid-rise apartment development as defined by the Trip Generation Report, 81h Edition, Volume 2 of 3 published by the Institute of Transportation Engineers. Page 384 of the Trip Generation Report shows the highest average peak hour trip rate is 0.44 per units which occurs on weekdays. Refer to Attachment "A" for the trip generation data. This property will only generate 124 trips during the peak hour according to the trip generation data. Therefore, this development will not have an significant impact on the traffic within the area and further traffic impact analysis is not warranted. Water System Design The largest building within the apartment complex is contains 35,034 square foot and is type V-B construction. Since the building is sprinkled, the required fire flow will be 1,650 g.p.m. However, the clubhouse is 6,909 square foot, type V-B construction and will not have a sprinkler system. The required fire flow for the clubhouse is 2,250 g.p.m. which must be provided by two hydrants as required by the International Fire Code. While providing the fire flow and in accordance with the BCS Unified Design Guidelines, the maximum velocity within the system is 12 f.p.s. and the system must maintain a residual pressure of 20 p.s.i. Refer to Figure "B'' for a layout of the proposed water system for this development. Two scenarios were analyzed to ensure proposed water system improvements are capable of meeting the above requirements. The system was first ran (Scenario 1) with a fire flow of 1,650 g.p.m. at a single hydrant which would produce the "worst" condition (J -15). During the second ran (Scenario 2), the system fire flow was 2,250 g.p.m. split between two hydrants Copperfield Parkway Apartments Design Report Page 1 MBESI No. 10000265 closest to the club house (i.e. the proposed hydrant directly in front of the clubhouse (J-18) and the hydrant just north of the club house(J-8).) Fire flow information from two fire hydrants located adjacent to the project site was obtained from City of College Station. Refer to the Attachment "B" that shows the location City Fire Hydrants G-099 and G-102. Following is a summary of the fire flow information provided by the City: Hydrant Flow Static Hydrant Residual (g.p.m.) Low Pressure Pressure (p.s.i.) (p.s.i.) G-099 1,455 100 92 G-102 1,455 101 93 Based on this information, the water model was analyzed using a pressure of 90 p.s.i. The water system model analysis shows that the maximum velocity and minimum pressure for Scenario 1 occurs in pipes P-15 and P-20 and is 11.2 f.p.s. and the minimum pressure is 82. 7 p.s.i.. For Scenario 2, the maximum velocity occurs in P-27 with a velocity of 11 .9 f.p.s. and a minimum pressure of 87.0 p.s.i which occurs at Junction J-4. Under both scenarios, the system maintains pressure well above 20 p.s.i. Refer to Attachments "C-1" and "C-2" for the analysis results for Scenario 1 and 2, respectively. Base on these results, the proposed water system is more than capable of providing fire flow protection to this site in accordance with the BCS Unified Design Guidelines. Drainage System Design Part 1 -Executive Summary The site is undeveloped and consisted of mostly grass cover, trees and brush. The property is has a gentle slope from the north to the south with the elevation at the north end around 295.00 to an elevation at the southern end of 278.00. Refer to Figure "C" that shows the proposed developed site drainage areas and the proposed stormwater drainage system. Runoff from site will be collected in a private drainage system that will discharge into the existing detention pond what was built as part of the Crescent Pointe development (i.e. Common Area "F" Detention Pond.) In accordance with the drainage report prepared by Kling Engineering & Surveying (KES) for the Crescent Pointe development, the detention pond was designed such that all of the stormwater runoff from the project site (i.e. Lot 3R) and future Lot 2 (i.e. estimated 4.77 acres) is to be conveyed through the Common Area "F" detention pond . Therefore, the drainage collection has been designed to convey the 100-year storm to the existing detention pond for both Lots 2 and 3R. A 36" storm pipe will be extended to the property line of Lot 2 for future use. The KES drainage report assumed an average runoff coefficient of 0.78 for post development conditions. The proposed post development runoff coefficient for the project is 0. 71; therefore, no improvement to the existing detention pond will be necessary. Copperfield Parkway Apartments Design Report Page 2 MBESI No. 10000265 The proposed drainage system for the development will consist of 8" to 42" HOPE pipe, curb inlet boxes , grate inlet boxes, junction boxes and necessary fittings to convey the water to the detention pond . Sizing of the grate inlets was based on a maximum depth of 3" and an assumed blockage of 25%, while curb inlets based on being at low points with a maximum throat depth of 9" and an assumed blockage of 10%. Attachment "D-1" shows the drainage areas, run off coefficients, flow rate per drainage basin and the required grate inlet or curb inlet. Grate inlets range from 12" x 12" to 34" x 34" and curb inlets range from 5' and 1 O' long. Attachment "D-2" shows the stormwater system model result for the storm drainage collection system analysis for a 100-year storm event. According to the KES drainage amendment letter, the maximum water elevation in the detention pond will be 279.9. The lowest grate inlet in the development is Grate Inlet #12 which is 279.40. During the 100-year storm event, the maximum water depth in the driveway will be 6 inches and will be isolated around the grate inlet. According to the Flood Insurance Rate Maps for Brazos County, Texas and Incorporated Areas, Map Number 48041 C0220E, revised May 16, 2012 this property is not located within a FEMA 100-year flood hazard area. Refer to Figure "D" for a portion of the FIRM map that shows the location of the proposed development. Parts 2 - 6 are included in the B/CS Unified Stormwater Design Guidelines, Technical Design Summary that is attached as Attachment "E". Conclusions Based on the trip generation information provided , the proposed development will not generate more than 150 peak hour trips and therefore a more detailed traffic impact analysis is not warranted. The proposed water distribution system and the existing water facility adjacent to the site will be adequate to provide the necessary domestic and fire protection for this project in accordance with BCS Unified Design Guidelines. The proposed storm water improvements for this project are anticipated to mitigate any impacts of the stormwater runoff from this development and will convey all stormwater to the existing Crescent Pointe Common Area "F" detention pond. Therefore, to the best of my knowledge, information and believe, this development will have no impacts on the adjacent or downstream property owners which is in accordance with the Bryan/College Station Design Guidelines.

Appendix D -Technical Design Summary Copperfield Parkway Apartments Design Report MBESI No. 10000265 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. 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 applications that are in process with either City: plat(s), site plans, zoning requests, STORMWATER DESIGN GUIDELINES Effective February 2007 Page 1 of 26 APPENDIX. D: TECH. DESIGN SUMMARY As Revised February 2009 SECTION IX APPENDIX D -TECHNICAL DESIGN SUMMARY 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."

Box 9960 College Station, Texas 77842 Re.: Copperfield Parkway Apartments Supplemental Drainage Information COCS No. 14-00900017 MBESI No. 10000265 Dear Carol, This letter is being sent to you to address your question regarding the impact on above referenced development if the outlet of the detention pond is blocked. The 100-year water surface elevation is 279.90 for the detention pond as per the Kling Engineering & Surveying drainage report. The pond's emergency overflow is at 280.00 and the top-of-berm elevation is 281.00. If the outlet of the pond is 100% blocked, the pond will first begin to overflow through the emergency overflow. If the emergency overflow cannot handle the incoming water, the water will begin to back up into the parking lot areas of the development. The back water will first begin to flow out of the parking area through the dumpster pad, which will have a finished elevation of 280.04 and is located at the very southern end of the property. If the water continues to rise, the back water will overflow the top-of-curb (±350 LF) along the southern property line which will be set at 280.61. The water that over tops the curb will sheet flow onto the adjacent property (TAMU property) which is approximate 2' to 3' lower. The 100-year flow into the pond is 309 cfs as per the Kling Engineering & Surveying drainage report. Therefore if 100% of the water was over topping the curb, the depth would be 0.41 feet (i.e. 281.02). Once the water reached 281.00, the water will be over flowing the detention pond berm and at other locations within the Crescent Pointe development. Please let me know if you have any questions or need any additional information regarding this matter. Sincerely, fdvt J. Dale Browne, Jr., P.E.

Box 9960 College Station, Texas 77842 Re.: Copperfield Parkway Apartments Supplemental Drainage Information COCS No. 14-00900017 MBESI No. 10000265 Dear Carol, This letter is being sent to you to address drainage impacts of the addition of three new parking areas within the above referenced development. The three parking lots will add approximately 36,914 square feet (0.85 acres) of impervious area to the development. The revised Grate Inlet and Curb Inlet Sizing Calculations (Exhibit "D-1 ") and the Stormwater System Model Results for the 100-year Storm Event (Exhibit "D-2") are attached. Based on the attached calculations, the proposed addition of the three parking lots will have minimal impact on the drainage improvements that have been installed. With the exception of Pipes 82, 83 and 84 (i.e. show in the original Figure "C"), the drainage system will be capable of handling the additional flow. Original Pipes 82, 83 , 84 and a junction box will be abandoned and new drainage pipes along with the associated structures will be installed that will be sized to carry the stormwater runoff from the new parking lot to be constructed northeast of Building 1. Also, the overall runoff coefficient will be increased from 0.71 (originally calculated) to 0.72. The revised overall runoff coefficient is still below 0.78 which was the assumed runoff coefficient by the original drainage report prepared by Kling Engineering & Surveying. Therefore, no improvements to the regional detention facility will be required due to the addition of the three parking areas. Please let me know if you have any questions or need any additional information regarding this matter. Sincerely, fdv& J. Dale Browne, Jr., P.E.

It appears that there are seventy-three (73) canopy trees on site. Please revise. 6. Please remove the symbols that are smaller canopy trees and streetscape trees as they are not included on this plan and are somewhat confusing on the planting schedule. 7. It appears that there are eight-three (83) shrubs -the circle symbol with no dot in the middle. Please revise the planting schedule to include the remaining shrubs. 8. Of the much smaller symbol (shown along the southern property line), there are at least ninety-six (96) screening shrubs. Please include these in the planting schedule. 9. Please include the pool court's landscaping in the planting schedule. This area also counts for site landscaping point credits. 10. Please revise the landscape points on site based on the requested revisions . 11 . Please include what plants will specifically be used on this site in the planting schedule rather than listing what plants are 'typical'. 12. Please revise the scientific name for Cedar Elm to Ulmus crassifolia and Shining Sumac to Rhus copal/ina. Reviewed by: Morgan Hester Date: February 10, 2014 ENGINEERING COMMENTS NO. 1 1. Add inlet protection to Crescent Point Drive along construction vehicle route. 2. Contractor may need to provide signage to keep construction vehicles from using non- construction access points. 3. Relocate retaining wall out of PUE. There is a concern that it could affect safety of our crews that may have to work on the sewer line in close proximity. 4. Portions of the water line appear to be closer than 20 feet from proposed structures (Bldg 2, Bldg 10 and Maintenance). Please adjust layout. 5. Landscape Plan shows canopy trees directly over existing public sewer and proposed water line. These trees may not only compromise the integrity of the infrastructure, but are typically destroyed during repairs with mature trees not easily replaced. Please revise Landscape Plan to either replace those canopy trees that are proposed directly over public infrastructure with non-canopy trees and/or shrubs, reduce number of canopy trees in conflict with these utilities, or relocate the utilities. Landscape point/planting requirement will still need to be achieved. 6. Fire flow Scenario 2 of the Water Report utilizes a hydrant across the street from this project. You will need to utilize one of the on-site hydrants as your second hydrant. Update model to reflect changes. 7. Please add storm and sanitary sewer layers to waterline Plan View (Sheets C5.0-C5.3) so that I may better check conflicts. 8. A minimum of 6" separation is needed between storm and waterline in order to get a clamp on the waterline . 9. Add valves to water line in accordance with Design Guidelines. Plans do not indicate any valves on the main lines, only the fire hydrant leads. 10. Provide radius of curvature at deflections in waterline, or call out fittings. 11 . FYI-Fire hydrant assemblies are called out at Sta 10+39.27 (WA-1) and Sta 2+24.02 (WA- 2), but not completely depicted in Plan View. 12. There is and exiting 8" waterline stub at southeast corner of property that may provide cost savings with the elimination of one of the bores. Existing 30' PUE along southern property line could also be utilized to provide loop to your system. 13. Indicate limits of structural backfill on plans . 14. Portions of the existing sanitary sewer line appear to be closer than 15' feet from proposed structures (Bldg 6, Bldg 11 and Bldg 12). Please adjust layout. 15. Clearly indicate in the construction plans that the proposed onsite sanitary sewer is private. 16. Flow lines in/out on private sanitary appear to be reversed. 17. Provide flowlines of public mains where you are proposing connection. 18. FYI-Contractor will need to pull plumbing permit for private sanitary sewer. This permit may need to be done ahead of full building perm it since part of site utility work. 19. Please confirm the WSELs mentioned in your Drainage Report (297s). Original Drainage Report for existing pond indicates water surface and berm elevations in the 279-281 range. 20. Although the 100 year WSEL for the existing pond is 279 .9, the Top of Berm elevation is 281 . If the overflow is blocked, how does this affect the ponding in your project? 21 . Please confirm that the pipe stub to the adjacent property to the north and subsequent downstream system is adequately sized to convey their 100-year flows to the existing detention pond as prescribed in the common drainage plan . Attachment D-2 appears to indicate Total Flow in excess of Full Capacity on several of the pipe segments. 22 . Fire Department is requesting a more continuous defining edge (like rollback or ribbon curb) to the grasscrete emergency access drive since the access drive will need to be clearly defined. It will also need to be painted red . 23. The City's preference is that Detectible Warning Pavers only be placed at public street intersections and/or signalized commercial driveways in accordance with TDLR. 24. Please include doghouse manholes in Engineer's Estimate. Reviewed by: Carol Cotter Date: February 10, 2014 FIRE 1. No combustibles will be allowed on site until all-weather roads and fire hydrants have been accepted by the City. 2. No more than a six percent (6%) grade is allowed on any length of fire lanes. 3. Fire lanes will be constructed using the "Fire Apparatus Turning Radius Template" and have a fire lane sign at the entrance. Curbs to be marked "Fire lane, No Parking, Tow Away Zone" with a minimum of four (4") letters. 4. A "Knox Box" security key system is required on all buildings and a Knox Switch is required on all gated entrances. 5.

Reviewed by: Steve Smith Date: January 29, 2014 ELECTRICAL COMMENTS REQUIRING IMMEDIATE ATTENTION 1. LOAD DATA: The developer will provide load data to CSU as soon as it is available. This information is critical for CSU to accurately determine the size and number of transformers, and other equipment, required to provide service to the project. Failure to provide load data will result in construction delays and , due to clearance requirements, could affect the final building footprint. Delivery time for transformers and other equipment not in stock is approximate 26 weeks . 2. EASEMENTS: Developer provides descriptive easements for electric infrastructure as designed by CSU, as shown on plat or site plan . 3. If easements are existing, the developer will be responsible for locating easements on site to insure that electrical infrastructure is installed within easement boundaries. GENERAL ELECTRICAL COMMENTS 1. Developer installs conduit per CSU specs and design. 2. CSU will provide drawings for electrical installation . 3. Developer will intercept existing conduit at designated transformers or other existing devices and extend as required . 4. If conduit does not exist at designated transformer or other existing devices, developer will furn ish and install conduit as shown on CSU electrical layout. 5. Developer pours electric device pads or footings, i.e. transformers, pull boxes, or other device, per CSU specs and design. 6. Developer installs pull boxes per CSU specs and design, Pull boxes provided by CSU. 7. Final site plan must show all proposed electrical facilities necessary to provide electrical service, i.e. transformers, pull boxes, or switchgears, all meter locations, and conduit routing as designed by CSU. 8.
