'\J --'~ IOlfA\..., .-~-1 {, Parking Lot Expansion College Station Institute of Religion I. General Location A. The project site is located at the intersection of Dexter and Old Jersey Street B. The Primary Drainage System that the site ultimately drains to is Bee Creek. the site is located in the upper reach of the creek in basin 3. II. Description of Property A. The site is a 1.3 acre tract with an existing building and parking areas. B. The purpose of the project is to expand the parking area from 10 spaces to 25 spaces. C. The additional parking spaces increase the impervious ground cover by 1,205 square feet or by 0.03 ·acres. D. The project also proposes to relocate and replace the existing 12" culvert between the existing parking area and the building with a 15" and 18" PVC drainage system. Ill. Drainage Basins and Sub-Basins A. The Primary Drainage System that the site drains to is Bee Creek. The site is at the most upstream reach of the creek and is found on the Flood Insurance Rate Map number48041C0144 C dated July 2, 1992. Though the 1" to 1000' scale of the maps are not accurate for such small areas, a portion of the site could be located in Zone X. This zone does not have a base flood elevation and is not mapped in the 100 year flood plain. B. The existing site drainage generally sheet flows to the southwest side of the tract. The only proposed impact of this project on the secondary drainage system will be from increasing the impervious area of the parking lot by 0.03 acres. Page 2 Parking Lot Expansion College Station Institute of Religion IV. Drainage Design Criteria A. The scope of this project from a drainage perspective is so small that the procedures for evaluating the impact outlined in the Drainage Policies and Design Standards manual are not applicable. The proposed improvement is only 1,205 square feet (0.03 acres). By inserting extreme values in the rational formula for the 25 year event (C=1, 1=10,A=0.03) yields a runoff for the parking area of 0.3 cfs. It would be impractical to attempt to detain any impact due to the proposed development for this project. V. Drainage Facility Design A. The proposed parking addition will collect runoff in area drain 2 as shown on SD-2 of the plans and will carry the flow to area drain 1 via a 12" pvc pipe. The overall drainage patterns for the site will remain the same as the existing conditions. VI. Conclusions A. No detention is recommended. As stated previously, the impact of such a small amount of development is impractical to quantify and would be very impractical to mitigate.
