STORMWATER DESIGN NARRTATIVE
BACKGROUND INFORMATION
Duke Energy Progress, LLC (DEP) intends to upgrade their existing Spring Hope 115kV
Substation located at 805 East Nash Street (US Hwy- 64 Alt.) in Nash County, North Carolina.
The 6.54-acre parcel is located 0.29 miles east from the intersection of NC-581 and US-64 Alt.
The existing grade of the site varies from 2 percent on substation pad to 13 percent in areas
surrounding the existing substation. The site contains approximately 0.50 acres of fenced
gravel substation/pad and an existing graveled access road.The remainder of the site is
grassed and wooded with understory growth.
A copy of the United States Geological Survey (USGS) map is attached (Appendix C) indicating
the project vicinity and general drainage patterns in the area.The United States Department of
Agriculture (USDA) soil survey map (attached) indicates the underlying soils within the project
area are predominantly Autryville Sand (AuB), Leon Sand (LnB), and Torhunta Fine Sandy Loam
(To).The Hydraulic Soil Group Classifications are A,A/D, and A/D respectively.
Stormwater runoff from the site discharges to Sapony Creek(Stream Index No.:28-55(1)).
According to the latest surface water classifications published by NCDEQ, Sapony Creek is
classified as C;NSW and is located within the Tar-Pamlico River Basin.The site does not drain to
Outstanding Resource Waters (ORW) designated waters; is not within %z - mile of and draining
to SA classified waters; and is not within 1-mile and draining to High Quality Water(HWQ)
designated waters.There are no known wetlands within the property boundary.
PROJECT DESCRIPTION
DEP plans to upgrade the existing substation internals which will require temporary
construction of a 115kV tap line and temporary mobile substation.The temporary mobile
substation footprint is 50-feet by 100-ft. DEP also plans to improve and widen the existing
gravel access road from East Nash Street to the substation fence as well as improving the
substation shoulders (6-feet gravel shoulder at 2%) to protect the grounding grid.
STORMWATER CONTROL NARRATIVE
The proposed project falls under the Low-Density category at 3.16% impervious. According to
the NCDEQ stormwater Design Manual (A-4: Built Upon Area), the area within the fenced yard
at electrical substations may be counted as pervious and this area has been excluded from the
overall impervious calculations. Surface runoff will be conveyed through grassed ditches where
applicable and discharge within the property boundary to existing grades or will drain back to
the ditch along East Nash Street.The proposed access road ditches are designed to convey the
10-year storm event. Prior to discharging, riprap outlet protection will be installed to dissipate
the velocity to ensure non-erodible velocities. Undisturbed areas within the project limits will
maintain existing drainage patterns.
