DEVELOPMENT SUMMARY

The site is located on Rea Road in Union County, NC, roughly 0.4 miles northwest of
the intersection of Rea Road and Tom Short Road. The 8.68-acre site currently consists
of open vegetated area with some trees and is zoned as PUD6-B2. The adjacent
parcels are a single-family residential subdivision, a day care, and an undeveloped
parcel. McBride Branch runs along the southwest property line and the entire site is
sloped downward from the roadway towards the creek.

PROPOSED DEVELOPMENT

The proposed development of the site includes four commercial buildings and
associated parking lots. The estimated build-upon area, including the concrete,
asphalt, and buildings, is 71.6%, based on the drainage area of 4.3-acres.

The storm drainage system will be installed in order to capture all on-site runoff and
route the stormwater to the sand filter dry detention pond. The pond has been designed
to treat the 1-inch water quality volume and attenuate the 10- and 25-year peak flow
rate. The stormwater will then be discharged along the existing slope where it will flow
into the creek. A riprap apron has been designed in order to avoid erosion issues.
