WETLANDS AND STORMWATER UGH

Existing Conditions
The existing site conditions were determined from a site field survey by Boswell
Surveyors, Inc. of Burlington, North Carolina and were supplied to BWSC by the
developer. The approximately 80 acre site is a composite of land parcels previously
undeveloped that are northeast and immediately adjacent to the Burlington Regional
Airport. The site was previously used as pasture and forest and is located in the Cape
Fear River Basin according to NCDENR. Soils mapping information from the U.S.
Department of Agriculture, Natural Resources Conservation Service web site
(httn://websoilsurvgy nres usda oy/app/WebSoilSurvey asmx) is included. The soil
survey shows primarily sandy clay loams which are classed as type C soils by for the
SCS method.
Proposed Conditions
The current planned facility will contain a corporate office building and an aircraft engine
production facility. The topography for the area planned for the facility drains to Gunn
Creek. Drainage from the facility will be collected into pipes and conveyed into a
detention pond which will empty to the stream. The pond is intended to serve all phases
of the development.
Methods and Assumptions
The hydrology and hydraulics were simulated in the inteliSOLVE Hydraflow
Hydrographs 2004 software and the Bentley CivilStorm software, V8 XM Edition. An
SCS approach was used for the curve numbers and times of concentration. The detention
pond was designed as a dry pond in order to avoid classification by the Federal Aviation
Administration as a hazardous wildlife attractant (Section 3, FAA Advisory Circular AC
No. 150/5200-33) and the resulting wildlife hazard mitigation techniques.
Results
The stage-storage relationship for the detention pond was calculated using Microsoft
Excel and an average end area approach. Data and a graph are enclosed. The required 1
year storm storage volume for water quality was calculated using Mathcad v13 by
Mathsoft Engineering and Education, Inc. The volume required was 49,904 cubic feet
and corresponds to an elevation of 544.28 in the proposed pond. The pond unfiltered
outlets were set at 544.3 which corresponds with a volume of 50,281 cubic feet. The
pond surface area at this elevation was calculated at 24,212.3 square feet. The City of
Greensboro Stormwater Management Manual was used to evaluate the particle size
removal efficiency. A 90% removal efficiency was assumed and a particle size of 4.6
microns was calculated as the minimum particle size meeting the 90% removal
efficiency.

Additionally, the one year event storm was routed and results are included for an
extended period of 2.8 days. Review shows the pond at final drawdown at around 2.74
days giving a residence time of about 2.3 days.
