The 119.35 acre parcel (PIN 0784132319) is undeveloped forest land. The parcel is located in the Crabtree Creek watershed in the Neuse River Basin. The overall drainage pattern for this site will remain unchanged as the site is developed. The site contains one main type of soil, Cecil, and has been determined to be in hydrologic group "B" per the Wake County soil report. The site does contain blue line streams but will not impact any buffers. The site is located within zone X, per FIRM map # 3720078400J dated May 2, 2006. PROJECT WATER MANAGEMENT Two underground sand filters and two underground detention systems are proposed in order to meet water quality and quantity requirements. The project will have an increase of 6.14 acres of impervious area on site. The sand filters will treat the first flush for 85% TSS for 5.88 acres of the increased BUA. The remaining untreated portion of impervious area is located at the entrances which is impractical to drain to the SCMs. The sand filters will also treat for nutrients such as nitrogen. The SNAP tool has been included in the report to calculate both the reduction in nitrogen loading and required offset to buy down. Underground detention systems will be connected downstream of the sand filters and will provide peak flow attenuation for the 1-year 24-hour storm. Routing results show that the post -development peak flow will not exceed the pre -development peak flow for this storm event.
