STORMWATER NARRATIVE

STORMWATER NARRATIVE
Proiect Description
This report addresses expected stormwater runoff and water quality for the proposed
development of a Biscuitville restaurant. The property is located on the corner of NC Hwy 24/87
and Percy Blvd. at the coordinates 35° 15'21.2076" N, 79° 2' 10.5756" W. The site is a vacant
property. The total site area is 1.06 acres and there is no existing impervious. After proposed
development, the site will have 28,030sf /0.64 acres impervious and 1,794sf /0.04 acres of
permeable paving.
Adiacent Areas
The site is a corner lot with commercial uses on adjacent parcels. Limits of disturbance for the
development will remain onsite with the exception of utility connections.
Existing Conditions
The runoff on-site sheet flows from the south to the northeast and an existing storm drainage
system. The proposed development will maintain existing drainage patterns.
Site Area =1.06 acres
Existing Impervious = 0.00 acres
Existing Open Space = 1.06 acres
The NRCS Soils Survey mapping shows that the soils on the site are:
CaB — Candor sand, belonging to hydrologic soil group A.
Proposed Conditions
The proposed construction will consist of one single -story 2,982sf building for a Biscuitville
restaurant, curb islands and associated parking. Majority of stormwater runoff will enter into a
conveyance system on-site that outlets into an existing stormwater detention pond in the rear of
property. The stromwater run-off in the front of building sheet flows to a permeable pavement
parking area along right-of-way.
Site Area =1.06 acres
Proposed Impervious = 0.64 acres
Proposed Open Space = 0.42 acres
Proposed Stormwater Management Requirements
The existing stormwater pond in the rear of site will be used to meet stormwater requirements.
The existing pond was approved for a maximum built upon area of 33,106sf for this site under
Permit No. SW6111206.
