Description This project consists of the construction of proposed professional building and associated parking areas and landscaped areas. Additional project activities include the construction of a proposed storm sewer system on-site as well as off- site for draining the site to the existing pond on east side of existing retail complex. u Existinq Site Description The site is presently undeveloped. Under existing conditions, the project site consists of grass and some trees that will be removed by the developer. A soil map from United States Department of Agriculture Soil Conservation Service identifies Miami (MmB2) soil on the property and is included in the Reference Maps. Existing drainage characteristics are such that the site generally sheet flows from the northwest corner of the site to the southeast corner of the site. Proposed Conditions Proposed drainage, for the developed site, consists of a system of new storm inlets and connecting pipes on-site and off-site. The proposed drainage system will convey the run-off from the subject site to the existing detention facility located on the northeast side from the site. The storm drainage system is designed to accommodate the direct runoff from the subject site. All new storm sewers are designed to accommodate a 1 O-year storm event using the Rational Method. Calculations are included in this report. u u v SOILS MAP '-' Mid-States Engineering, L.L.C. STOR~I DRAIN FLO\\"TABlLATION FOR)!
