Section I has been constructed and the final plat has been recorded. Tanglewood Section E contains 67.95 acres and is located adjacent to US 17 South and Forman Bundy Road. Lot 4, Section D is a 1.91 -acre adjacent lot that is to utilize the drainage system that has been created for Section E. The total site area is 69.86 acres . The site is located in Pasquotank County zoning jurisdiction. The majority of soils found on the site is Roanoke and poorly drained. The site is drained predominately by a large ditch system that is comprised of US 17 roadside drainage. The main outlet for the subdivision travels south along US 17 to the headwaters of the Little River. Pasquotank County subdivision regulations have required a drainage review of this subdivision by the local USDA-NRCS representative, Dwane Hinson. The review of this drainage by Dwane required a HEC-RAS analysis of the downstream drainage system. During this modeling, it was determined that the downstream drainage was not capable of handling a 2 yr 24hr rainfall event. Based upon this finding, we are required to elevate finish lot grades to 14.5 If ASL and provide on -site storage of rainfall events in proximity of the I Oyr event. on -site storage of storm water was accomplished by constructing a surrounding drainage ditch.?N 4., A ZZ lize thisZ 0 de slopes.

This s sf of surface area of storm water wetland pocket and 83 470 sf of surface of swale. Based upon these numbers land treatment. we are rovi in m In addition to providing the SWWP's and the swale system, outlet control devices have been installed in the form of rip -rap protected earthen weirs with 4" pvc draw down pipes.
