Dear Mr. Randall,
On behalf of Duke Energy Progress, and in regards to the referenced project, we are enclosing the
following for your review and approval:
• Two (2) copies of the executed Stormwater Management Permit Application
• $505 Application/Review Fee (DEP Check # 1000031488)
• Two (2) copies of the Low Density Supplement Form ��/
• Two (2) sets of Construction Plans 87
16
• Copy of Stormwater narrative & USGS Map
• Copy of Current Deed ¢Rlyiyy NDQ��
• Copy of Wetland Determination Report (prepared by ESI, Inc.) A%Rp�R077-ING
The proposed project will involve the expansion of an existing electric substation facility located on
Hunting Ridge Road in Hope Mills, NC. The project will disturb 4.94± acres of the 10.2 acre site. Site
improvements will include the following: (1) 2nd transformer bank addition (expand fenced area by
120'x205') with gravel surface for weed control; (2) Add 2"d gravel access drive: (3) Provide 20' gravel
access around exterior perimeter of expanded fence area; (4) Resurface (remove & replace) existing
substation yard gravel.
We trust this information is complete and will allow approval at an early date. Should you have
questions or require additional information, please let us know.
Sincerely,

STORMWATER MANAGEMENT PERMIT APPLICATION FORM
LOW DENSITY SUPPLEMENT
This form may be photocopied for use as an original
A low density project is one that meets the appropriate criteria for built upon area and transports stormwater
runoff primarily through vegetated conveyances. Low density projects should not have a discrete stormwater
collection system as defined by 15A NCAC 2H .1002(18). Low density requirements and density factors can be
found in Session Law 2008-211, 15A NCAC 2H .1000, Session Law 2006-246 and the State of North Carolina
Stormwater Best Management Practice Manual. Curb and gutter systems are allowed provided they meet the
requirements in 15A NCAC 2H .1008(g).

Number of Dwelling Units Per Acre**:
Low Density Development (check one): ® without curb & gutter ❑ with curb & gutter, outlets to (check one):
❑ Swales ❑ Vegetated Area
*If lot sizes are not uniform, attach a table indicating the number of lots, lot sizes and allowable built upon area for each lot.
The attachment must include the project name, phase, page numbers and provide area subtotals and totals. BUA shall be
shown in units of square feet.
**(Phase II Post -Construction [non -SAI only)
II. BUILT UPON AREA
Refer to DEMLR's forms and applications website for specific language that must be recorded in the deed
restrictions for all subdivided projects. (http://portal.nedenr.org/web/lr/state-stonnwater-fonns®docs)
Complete the following calculation in the space provided below where:
• SA Site Area - the total project area above Mean High Water.
• DF Density Factor - the appropriate percent built upon area divided by 100.
• RA Road Area - the total impervious surface occupied by roadways.
• OA Other Area - the total area of impervious surfaces such as clubhouses, tennis courts, sidewalks, etc.
• No. of Lots - the total number of lots in the subdivision.
• BUA per Lot - the computed allowable built upon area for each lot including driveways and impervious
surfaces located between the front lot line and the edge of pavement.
• Total allowable lot BUA - the computed allowable built upon area for all lots combined.
• Total BUA from lot listing - the sutra of built upon area allocated for each lot on the list of non-uniform lots.
Form SW401-Low Density-Rev.3-2/10/09 Page 1 of 4

Calculation:
For uniform lot sizes:
(SA: 445,183.20 ft2 x DF: .24) - (RA: 0 ft2) - (OA: 0 ft2) = BUA per Lot = 106,843.97 ft2
(No of Lots: 1)
For non-uniform lot sizes:
a. (SA: ft2 x DF: ) - (RA: ft2) - (OA: ft2) = Total allowable lot BUA = ft2
b. Total BUA from lot listing: sf. b must be < a

V. SWALE SYSTEM MAINTENANCE REQUIREMENTS
Mowing will be accomplished as needed according to the season. Grass height will not exceed six inches at
any time; and grass will not be mowed too close to the ground or "scalped".
