The sanitary sewer has been prepared in general conformance with the requirements of College Station and TxDOT. The purpose of the report is to verify adequate capacity of the proposed sanitary sewer line for the drainage area discharging into the system for the commercial development. This sanitary sewer analysis consists of this narrative plan, the accompanying exhibits included in the appendices. PROJECT DESCRIPTION Location and Outfall Information The site is located is at approximately Latitude 30° 33' 31 " N and Longitude 96° 15' 40" W determined using the USGS map. The site is located in the Wellborn SE Quadrangle Brazos County, Texas. The site slopes to the west and northwest of the property. Existing Conditions The site of the project is located approximately at the west corner of the intersection of Highway 6 and Highway 40 in College Station, Texas. The site is bounded by Highway 6 to the north, Highway 40 to the east and private development to the south and west. The project size is approximately 32 acres in size and is currently not developed. The site consists of primarily rocky soil with minimal vegetation. Sanitary Sewer Report Tower Point Infrastructure Development Page 2 Proposed Site Conditions Proposed development consists of a commercial retail shops with associated parking, drives, sidewalk, and landscaping. The public infrastructure being constructed consists of new public roadways, public water mains, public storm sewer systems, and public sanitary sewer systems. The public sanitary sewer will be connected to an existing 1 O" PVC sanitary sewer system located at the east of the existing round-about. The new sanitary sewer extension will be extended to the south and southeast along the new private drive C with lateral lines stubbed for future development on the west and southwest portion of the development. Two additional sanitary sewer lines will be extended from private drive C to the HEB property line to serve the HEB gas station and retail center (See Exhibit 1). HEB engineers will design the sanitary sewers within the HEB site. SANITARY SEWER ANALYSIS Existing Analysis The existing sanitary sewer manhole at the east side of the round-about which is the point of connection collecting approximately 34.5 acres of commercial development (See Exhibit 2). The existing 1 O" PVC sanitary sewer system at the round-about has a maximum peak hourly flow of 7. 76x1 QA5gpd or 1.20cfs and slopes to the northwest along Arrington Road. Proposed Analysis The proposed sanitary sewer drainage area discharging to the existing system is analyzed below: A=34.5 acres Capita=30 persons/acre Retail=25gpd/person Design (8" PVC) => Q Average Daity Flow = 25,875gpd Q Peak Hourty Flow = ( Q Average Daity Flow )* ( 4) Sanitary Sewer Report Tower Point Infrastructure Development Page 3 Proposed Site Conditions Proposed development consists of a commercial retail shops with associated parking, drives, sidewalk, and landscaping.

The existing 1 O" PVC sanitary sewer system at the round-about has a maximum peak hourly flow of 7.76x1 QA5gpd or 1.20cfs and slopes to the northwest along Arrington Road. Proposed Analysis The proposed sanitary sewer drainage area discharging to the existing system is analyzed below: A=34.5 acres Capita=30 persons/acre Retai l=25gpd/person Design (8" PVC)=> 0 Average Daily Flow = 25,875gpd Q Peak Hourly Flow= {Q Average Daily Flow )*{4) Sanitary Sewer Report Tower Point Infrastructure Development Page 3 Q Peak Hourly Flow = 1 Q3,50Qgpd Or 0.16cfS FUTURE DEVELOPMENT The sanitary sewer for the future development to the north, northwest, and west of HEB will be designed and submitted to the city for approval as Jots are developed for each phase. CONCLUSION The existing sanitary sewer system has adequate capacity to handle the new sanitary sewer flows discharging to the existing system at the connection point located east of the existing round-about.
