OF ~~•a Date ~yiJ~'~ €~{ ........ "tT l' KENTM . Ii! ~e?iJ OS SUMMARY "'(~\.~--- ~,~~,- The A&M Church of Christ plans to add overflow parking on the east and west sides of their existing facility . This additional parking requires modifications to the existing drainage system . These modifications include the construction of a new detention pond on the west side of the site and a reduction in size of the existing detention pond on the east side of the site . Modifications also include the relocation of inlets and the eh.'tension of underground pipes to carry water to the t\vo ponds . All of these changes are designed to integrate with the existing drainage system . The modified drainage system for the A&M Church of Christ meets all requirements of the City of College Station 's Drainage Policy and Design Standards . It will effectively control the stonnwater runoff from the site with no significant adverse impacts to the surrounding or downstream properties . The information that follows shows the parameters under which the design was prepared. Specific details are included in the applicable exhibits at the end of the report. GENERAL INFORMATION Area encompassed by entire facility: Anticipated land use : Notes on surrounding development : FLOOD HAZARD INFORMATION FEMA FIRM Map#: 48041COI61 C Effective Date: July 2, 1992 29.35 acres Church and associat ed parking lots The work associated with this project is an expansion of the recently completed church facility . All of the new work lies within the bow1daries of the existing site . Bordering the existing site on the east is the Raintree Subdivision, Section 2. The south side is bordered by property owned by Northrop Grumman Corporation. The West is bordered by the Earl Rudder Freeway (Sii 6 Bypass). Comments: No portion of the site is shown to be within the 100-year floodplain, so it is not currently regulated under the National Flood Insurance Program . Applicable Exhibits: A -· Excerpt of FEMA FIRM DESCRIPTION OF DRAINAGE SYSTEMS Primary System: The site was cleared, graded and landscaped with the original church construction . The parking lot expansion will be made on grassy fields adjacent to the existing parking lots . Natural drainage of the site is toward the northeast and southeast comers of the site where it flows into un-named tributaries of Wolf Pen Creek. Secondary System : Runoff from most of the site will be captured in the driveways and pa rking areas whe re it is directed into inlets and flumes that lead to the detention facilities . As indicated in th e original drainage report, there is one significant drainage area that b ypasses the storm drain system and detention pond . It is an undeveloped section of the site and there are no plans for development at this time . Runoff from this area is included in the peak flow calculation to accurately reflect all pre"'1evelopmcnt and post"'1evclopment flowrntcs . There is one other undeveloped area in the southwest comer of the site that drains into a separate outfall . This area is not being developed and its runoff rate is unchanged. Applicable I'<.xhibits : B-1 -Drainage Arna Map (Proposed Conditions) SECONDARY STORM DRAIN DESIGN General Note : The secondary drainage system is privately owned and maintained by the church . No underground pipes or inlets are dedicated to the public . The system consists of inlets and underground pipes that carry runoff from the building and parking areas to the two detention ponds . DETENTION REQUIREMENTS General Note: Detention Ponds l and 2 will work in series. The outfall from Pond 1 will flow to Pond 2 . The outfall from Pond 2 flows to Study Point A .
