Site Description:
The subject site is 25.18 acres total. The site is situated South of Church Street, East of Freedom
Lane and North of Rockfish Creek, and approximately 2975' East of the intersection of NC 59
(Main Street) and SR 2996 (Church Street). The site has a cummulative wetland area of 9.55
acres. The site is covered by mature trees with thick undergrowth. There is a Fayetteville Public
Works Commission Sewer Main traversing the property, as well. The site is naturally divided
into two (2) drainage basins.
Description of Development:
The project will consist of a 60 lot (single family) subdivision, served by public water and
sanitary sewer. The roads will be built to NCDOT standards, with subsequent drainage.
Drainage Area #1 will have 41 single family residential lots.
Drainage Area #2 will have 19 single family residential lots..
The entire project collectively, and Areas #1 & #2 individually, will have less than 24%
impervious area. The DWQ 401 Section has classified Area #1 (only) as a High Dens' Area
and has, therefore. required a BMP to handle this drainage basins storm drainage collection
s sV tem.
V
Page 2 of 2
Stormwater Impact:
There will be no stormwater impact to surrounding properties. Infrastructure is being installed to
handle off-site stormwater discharge. There will be no impact to the downstream property, in
that a wet-detention pond (based on 90% TSS removal), will be installed to control the post-
development stormwater discharge rate to the pre-development discharge rate.
Stormwater Management System:
A Wet-Detention Pond (90% TSS Removal) is being utilized to handle the storm drainage
system discharge. Lots 27 - 46 are not being diverted to the wet-detention pond, in that each lot
will have at minimum of a 35' buffer to the rear of each lot. Additionally, each of these lots will
have, at most, approximately, 20% impervious area.

Wet Detention Basin Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
The wet detention basin system is defined as the wet detention basin,
pretreatment including forebays and the vegetated filter if one is provided.
This system (check one):
? does ® does not incorporate a vegetated filter at the outlet.
This system (check one):
? does ® does not incorporate pretreatment other than a forebay.
Important maintenance procedures:
- Immediately after the wet detention basin is established, the plants on the
vegetated shelf and perimeter of the basin should be watered twice weekly if
needed, until the plants become established (commonly six weeks).
- No portion of the wet detention pond should be fertilized after the first initial
fertilization that is required to establish the plants on the vegetated shelf.
- Stable groundcover should be maintained in the drainage area to reduce the
sediment load to the wet detention basin.
- If the basin must be drained for an emergency or to perform maintenance, the
flushing of sediment through the emergency drain should be minimised to the
maximum extent practical.
- Once a year, a dam safety expert should inspect the embankment.
After the wet detention pond is established, it should be inspected once a month and
within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a
Coastal County). Records of operation and maintenance should be kept in a known set
location and must be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.
