STORMWATER MANAGEMENT PERMIT APPLICATION FORK[
LOW DENSITY SUPPLEMENT N1 WMI
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

•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 2008-21 1.
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 any item is not met,
then _iustification must be attached. Only complete items n through p for projects with curl) outlets.
Page/Plan�At
Initials Sheet No.
a. f For projects in the 20 coastal counties: Per NCAC 2H.1005, a 50 foot wide vegetative buffer
is provided adjacent to surface waters. For Redevelopment projects, a 30' wide vegetative
buffer adjacent surface waters is provided.
b. t For HQW or ORW projects outside the 20 coastal counties: A 30 foot wide vegetative
buffer is provided adjacent to surface waters.
C. t For Phase II Post -Construction projects: All built upon area is located at least 30 feet
landward of all perennial and intermittent surface waters.
d. Deed restriction language as required on form SWU- l 01 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.
f. Project conforms to low density requirements within theplieable-per
15 f1-I 1W si -u1c. �
g. Side slopes of swales are no steeper than 3:1; or no steeper than 5:1 for cci oi�twales.
h. Longitudinal slope of swales is no greater than 5%; fornon-curb outlet projects,
calculations for shear stress and velocity are provided if slope is greater than 517o.
i. At a minimum, swales are designed to carry the 10 year storm velocity at a non -erosive rate.
j. Swales discharging to wetlands are designed to flow into and through the wetlands at a non -
erosive velocity (for this flow requirement into wetlands, non -erosive is velocity a 2 ft/s).
k. Swale detail and permanent vegetation is specified on the plans.
1. Swale detail provided on plans; includes grass type(s) for permanent vegetative cover.
m. Swales are located in recorded drainage easements.
n.tt Length of Swale or vegetated area is at least 100 feet for each curb outlet.
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).
p." 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.
S. 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.
