The line will service th e proposed development of Phase 1 of the Spring Creek Townhomes Subdivision . 2.0 SANITARY SEWER -Design Flow and Pipe Size Calculations The proposed sewer line is to be constructed of 6"and 8" diameter SDR-26, PVC pipe which meets the requirements of ASTM-D3034. Four of the proposed manholes are 4 ' in diameter, and the one tying into the existing 27" line is 6' in diameter. The manholes vary from 9' to 20' in depth, with sewer line slopes ranging from 0.4% to 2.0%. The maximum distance between manholes is 189', which is less than 500 feet, as required by the Texas Commission on Environmental Quality (TCEQ). The minimum allowable slopes fo r 8" and 6" pipes per TCEQ requirements are 0.33% and 0.50% respectively. All construction shall meet the current City of College Station Standard Specifications for Sanitary Sewer Construction. The sewer line information is summarized in Table 1. 3.0 DETERMINATION OF PEAK FLOW VALUES The peak flows were based on using a daily use of 300 gallons per day for each dwelling unit. The design peak flow is determined by multiplying the average daily flow by 1.5, which results in the adjusted dai ly flow. This value is then multiplied by 3.0 to detem1ine the peak hourl y flow. The velocities for the lines were calculated using Manning's Equation. According to the TCEQ, the minimum velocity for sewer systems flo wing full is 2.0 feet per second. As shown in Table 1, the minimum anticipated flow velocities for the proposed sewer lines at 50% full meet this requirement. The flow for 100% full will not be less than the flow for 50% full; therefore, the TCEQ requirement is met. The TCEQ requires that the maximum velocity for sewer systems flowing full not exceed l 0 feet per second. The values in Table 1 are well below this maximum ve locity.

GENERAL LOCATION AND DESCRIPTION The project is located on a portion of a 62.18 acre tract located north of Greens Prairie Road along the West Frontage Road of State Highway 6 in College Station, Texas. This report addresses Phase 1, which is made up of 4.120 acres of the 62.18 acre tract. The site is pastureland with approximately 30% of the area wooded. The existing ground elevations range from elevation 268 to elevation 284. The general location of the project site is shown on the vicinity map in Exhibit A. FLOOD HAZARD INFORMATION The project site is located in the Spring Creek branch of the Lick Creek Drainage Basin. A portion of the site is located within a special flood hazard area according to the Flood Insurance Rate Map prepared by the Federal Emergency Management Agency (FEMA) for Brazos County, Texas and incorporated areas dated February 9, 2000, panel numbers 48041C0205-D and 48041C0201-D. LJA Engineering & Surveying, Inc. submitted a Request for Conditional Letter of Map Revision (CLO MR) to FEMA to outline a proposed 100-year floodplain area. This CLOMR No. 00-06-844R was approved by FEMA on 91912000. A proposed common area lies partially in this proposed floodplain. DEVELOPMENT DRAINAGE PATTERNS Prior to development, the runoff flows in a southerly direction until it enters a tributary of Spring Creek or into the proposed regional detention facility. DRAINAGE DESIGN CRITERIA The design parameters for the storm sewer are as follows: • Design Storm Frequency Stonn Sewer system 10 and 100-year storm events • Runoff Coefficients Post-development (townhomes) c = 0.65 • Rainfall Intensity val ues for Brazos County for a minimum time of concentration of I 0 minutes can be found in Table 1. Where a longer time of concentration was necessary, it is noted in the respective table, and the intensities are calculated with the hi gher va lu es where req uired. J • Time of Concentration, tc -A tc of 10 minutes is used to detennine the rainfall intensity values. Where a longer time of concentration was necessary, it is noted and used accordingly. STORM WATER RUNOFF DETERMINATION The peak runoff values were determined in accordance with the criteria presented in the previous section for the 5, 10, 25, 50, and 100-year stom1 events. The runoff coefficients are based on the future development of this tract. Exhibit A shows the post-development drainage areas for the evaluation of the runoff in Spring Hill Drive. This runoff was determined using the Rational Equation. These results are summarized in Table 2.

The detention facility is located adj acent to Spring Creek prior to Spring Creek entering the State Highway 6 right- of-way. The location of this proposed detention fac ility is shown on Exhibit A. The runoff from this project flows into the existing drainage channel constructed with the detention facility or into the detention pond. The detention facility was designed to control the increased runoff from the development of the Castlegate Subdivision and the Crowley Tract. Refer to the Request for Conditional Letter of Map Revision (CLO MR) for details of the design of the detention facility. STORM SEWER DESIGN There is no storm sewer piping or inlets proposed for thi s phase of this project. Future inlets were designed based on a l 0-year design stom1. As per College Station guidelines, the capacities of inlets in sump were reduced by l 0% to allow for clogging. Calculations concerning future inlets will be addressed in subsequent drainage reports. Evaluation of the gutter flow on Spring Hill Dri ve involved verifying the gutter flow depth was 7" or less. This design depth wi II prevent the spread of water from reachin g the crown of the road fo r th e IO-year stom1 event. The depth of fl ow in the gutter was determined by using the Straight Crown Flow eq uation.

The runoff will be coll ected in the street gutters and directed into a fut ure storm sewer system or detention pond, whi ch will adequately control th e runoff and release it into the existing drainage channel. Also, the regional detention facility should adequately reduce the peak post-development runoff to less than the pre-development runoff for the design storm event. This wi ll prevent any impact on the properties downstream of this project. 6 EXHIBIT A Post-Development Drainage Area Map 7
