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).
1. PROJECT INFORMATION
Project Name : BRE NC Solar 1. LLC
Contact Person: Richard Wright Phone Number: ( 804 )912 -7999
Number of Lots:I Allowable Built Upon Area (BUA) Per Lot *:31,537
Number of Dwelling Units Per Acre* *:N /A
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 Q Post - Construction [non -SA] 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. (httn: / /nortal.ncdenr.ora/web/Ir /state- stonnwater -forms 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 sum 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: 1.576,872 ft2 x DF: 0.02) — (RA: 0 ft2) — (OA: 0 ft2) = BUA per Lot = 31,537 ft2
(No of Lots: j)
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
III. DESIGN INFORMATION
Complete the following table. If additional space is needed the information should be provided in the same
format as Table 1 and attached to this form. Rainfall intensity data can be found in Appendix 8.03 of the State
of North Carolina Erosion and Sediment Control Planning and Design Manual or at

IV. REQUIRED ITEMS CHECKLIST
The following checklist outlines design requirements per the North Carolina Administrative Code Section 15A
NCAC 2H.1000, NCDENR BMP Manual (2007), Session Law 2006 -246, and Session Law 2008 -211.
Please indicate the page or plan sheet numbers where the supporting documentation can be found. An
incomplete submittal package will result in a request for additional information. This will delay final
review and approval of the project. Initial in the space provided to indicate that the following requirements
have been met and supporting documentation is provided as necessary. If the applicant has designated an agent
on the Stormwater Management Permit Application Form, the agent may initial below. If anv item is not met.
then iustification must be attached. Only complete items n through p for projects with curb outlets.
Page/Plan
Initials Sheet No,
N/A a. tFor projects in the 20 coastal counties: Per NCAC 2H.1005, a 50 foot wi&vegetative buffer is
provided adjacent to surface waters. For Redevelopment projects, a 30' wide vegetative
buffer adjacent surface waters is provided.
N/A b. tFor HQW or ORW projects outside the 20 coastal counties: A 30 foot wide vegetative buffer is
provided adjacent to surface waters.
N/A c. tFor Phase lI Post - Construction projects: All built upon area is located at least 30 feet landward of
all perennial and intermittent surface waters.
N/A d. Deed restriction language as required on form S WU -101 shall be recorded as a restrictive
covenant. A copy of the recorded document shall be provided to DWQ within 30 days of
platting and prior to the sale of any lots.
e. Built upon area calculations are provided for the overall project and all lots.
N/A f. Project conforms to low density requirements within the ORW AEC. (if applicable per
15A NCAC 2H .1007)
N/A g. Side slopes of swales are no steeper than 3:1; or no steeper than 5:1 for curb outlet swales.
N/A h. Longitudinal slope of swales is no greater than 5 %; for non -curb outlet projects, calculations for
shear stress and velocity are provided if slope is greater than 5 %.
N/A i. At a minimum, swales are designed to carry the 10 year storm velocity at a non - erosive rate.
N/A j. Swales discharging to wetlands are designed to flow into and through the wetlands at anon-
erosive velocity (for this flow requirement into wetlands, non - erosive is velocity <_ 2 ft/s).
N/A k. Swale detail and permanent vegetation is specified on the plans.
N/A 1. Swale detail provided on plans; includes grass type(s) for permanent vegetative cover.
N/A m. Swales are located in recorded drainage easements.
N/A n.tt Length of swale or vegetated area is at least 100 feet for each curb outlet.
N/A o.tt The system takes into account the run -off at ultimate built -out potential from all surfaces
draining to the system (delineate drainage area for each swale).
NIA p.tt Curb outlets direct flow to a swale or vegetated area.
t Projects in the Neuse, Tar - Pamlico, Catawba River basins, and Randleman Lake may require additional buffers.
tt Only complete these items for projects with curb outlets.

V. SWALE SYSTEM MAINTENANCE REQUIREMENTS
1. 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 ".
2. Swales will be inspected monthly or after every runoff producing rainfall event for sediment build -up,
erosion, and trash accumulation.
3. Accumulated sediment and trash will be removed as necessary. Swales will be reseeded or sodded
following sediment removal.
4. Eroded areas of the swales will be repaired and reseeded. Swales will be revegetated as needed and in a
timely manner based on the monthly inspections. Side slopes must be maintained at the permitted slope.
5. Catch basins, curb cuts, velocity reduction devices, and piping will be inspected monthly or after every
significant runoff producing rainfall event. Trash and debris will be cleared away from grates, curb cuts,
velocity reduction devices and piping.
6. Swales will not be altered, piped, or filled in without approval from NCDENR Division of Energy, Mineral
and Land Resources.
I acknowledge and agree by my signature below that I am responsible for the performance of the six
maintenance procedures listed above. I agree to notify DEMLR of any problems with the system or prior to any
changes to the system or responsible party.
