The parameters used for design and the existing conditions of the on-site area are incorporated to show how the final drainage design will accomplish the desired drainage objectives per the City of College Station Drainage Policy and Design Standards (DPDS.) GENERAL LOCATION AND DESCRIPTION: The proposed Center is located in the central portion of College Station. The site is located on Brentwood Street 700' east of Texas Avenue. The site is undeveloped and is gently rolling with an average of 1.5% slopes. PRIMARY DRAINAGE BASIN DESCRIPTION: The site drains to the northern right of way line of Brentwood.. The curbs convey the storm water to an inlet , and into an unnamed tributary of Bee Creek. No portion of the site is within the 100 year flood plain per the Federal Emergency Management Agency Flood Insurance Rate Maps for Brazos County, Texas and Incorporated Areas effective July 2 , 1992. STORM DRAINAGE REPORT HOPE PREGNANCY CENTER PAGE 1 DRAINAGE FACILITY DESIGN: The site will be served by a detention pond located in the parking area next to the southern property line . Exhibit "B-2" shows the proposed drainage areas for the pond. Drainage area "POND" flows to the Detention Pond and drainage area "BYPASS" is not detained by the Detention Pond. Exlnbit "B-1" shows the existing conditions drainage area. The study point for the project is the curb line of Brentwood where flows from the proposed detention facility and flows circumventing the detention pond come together. The outlet device for the pond is a 12" wide weir with an invert elevation of 295.00'. The top of berm elevation for the pond is 296.30'. DRAINAGE DESIGN CRITERIA: All drainage design is in accordance with the City DPDS. The design rainstorm is the 10 year event. Flow calculations for all drainage areas are based on the Rational Method. The storage volume required for the detention facility is based on a triangular hydrograph (base = 3* Tc) and peak flows computed using the rational method. The required volume shall be determined by the Storage-Routing Analysis. The proposed detention pond routings shown in Exhibit "D-1" and "D-2" demonstrate how the pond will :function. Exhibit "D-3" shows a stage storage and stage discharge curve for each pond. The following summary table shows the peak flow for the Pre-development events and the peak flows for the Post-development events.

The de tention pond discharges into the curb line near the Pre-development location. The drainage design for this site meets the requirements as stated in the City of College Station Drainage Policy and Design Standards.

DRAINAGE FACILITY DESIGN: The site will be served by a detention pond located in the parking area next to the southern property line. Exhibit "B-2" shows the proposed drainage areas for the pond. Drainage area "POND" flows to the Detention Pond and drainage area "BYPASS " are not detained by the Detention Pond. Exhibit "B-1" shows the existing conditions drainage area The study point for the project is the curb line of Brentwood where flows from the proposed detention facility and flows circumventing the detention pond come together. The outlet device for the pond is a 12" wide weir with an invert elevation of295 .00'. The top of berm elevation for the pond is 296 .00'. DRAINAGE DESIGN CRITERIA: All drainage design is in accordance with the City DPDS. The event. Flow calculations for all drainage areas are based on the Ra The storage volume required for the detention facility is b: (base= 3* Tc) and peak flows computed using the rational method determined by the Storage-Routing Analysis. the pond will function Exhibit "D-3" shows a stage storage and stage discharge curve for each pond. The following summary table shows the peak flow for the Pre-development events and the peak flows for the Post-development events.
