The line is proposed to be constructed on the Marsh-Reeves Property located north of the intersection of State Highway 6 and Green's Prairie Road in College Station, Texas . The initial purpose of the line is to provide sanitary sewer service to a 1.75 acre tract located at the southwest comer of the property (at the intersection of SH 6 and Green's Prairie Road). The line has been designed to provide service to this tract as well as provide service for future development of the property. Approximately 60 acres of property is available for future development that could utilize this line. No additional area is proposed to be served by this line since this area is bounded by SH 6 , Green's Prairie Road, Spring Creek and the proposed Pebble Hills Subdivision. 2.0 Design Characteristics The alignment of the proposed sewer line is shown on Exhibit 1. The line is 2 ,548 ' in length and drops 38 feet in elevation. There are eight manholes and 7 sections of pipe. The line will tie into the proposed Spring Creek 27" Collector Line that is scheduled for construction in the near future . The sewer line is proposed to be constructed using SDR- 26 PVC pipe which meets the requirements of ASTM D3034 . The diameter of the sewer pipe varies in size from 6" to 12 ". The proposed manholes are 4 ' diameter manholes except for Manhole No . 8, which ties into the 27" line, and is a 6 ' diameter manhole . Due to its proximity to the 100-year floodplain, Manhole No . 8 shall have a watertight ring and cover. The manholes vary in depth from 9 ' to 13' in depth and 3 have drop connections. The maximum distance between manholes is 437 feet and there are no curves in the lines . All construction shall meet the current City of College Station Water and Sewer Specifications . 3.0 Design Flow and Pipe Size Calculations The property was divided into 3 areas for determining the flows for future development of the property. These areas are shown on Exhibit 1. The design flows were based on the Gross Area Determination Method as presented in the "draft" Uniform Design Manual for the Cities of Bryan & College Station . The calculations of the design peak flows are as follows : Determination of Design Flow Average Daily Design Flow (Tributary Area less than 250 acres)= 7,000 gpd/acre Adjusted Daily Flow = Avg . Daily Flow* 1.5 Peak Hourly Flow = Adjusted Daily Flow * 3 .0 Peak Flow = 7,000 gpd/acre * 1.5 * 3 .0 = 31 ,500 gpd/acre Estimated Infiltration = 1,500 gpd/acre Design Peak Flow= 33 ,000 gpd/acre = 22.9 gpm/acre -0.05 cfs/acre / Table 1 -Sewer Line Flow Data Total Velocity,. fps Line Pipe Slope Service Design Design Min .

The design flows for Lines 3,4,5 and 6 were calculated by taking one-fourth the area of Area 2 and adding it to the previous total service area acreage. The velocities for the lines were calculated using Manning's Equation. As shown in Table 1, the minimum and maximum anticipated flow velocities for the proposed sewer line area within the acceptable limits of 2.5 fps for minimum velocity and 8.0 fps for maximum velocity. 4.0 Conclusions It is our determination based on the describ ed criteria and data that the proposed sewer line will provide sufficient capacity for the antieipated wastewater flows generated by future development. 5.0 Cost Estimate Table 2 presents the Engineer's cost estimate for the construction of the sewer line .
