local stormwater requirement, etc.):
Current land use in the vicinity of the pond:
Size of watershed draining to pond: Expected pond surface area:
VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts. The proposed impacts will
provide the necessary road and utilities to construct the proposed residential neiuhborhood.
Road impacts have been minimized by crossing the proposed stream at a perpendicular angle and
utilizing headwalls to decreasing the volume of fill and subsequent fill slopes. The ROW for this
extension was~reviously dedicated and the existing road stubbed just short of the crossm~ so
there was no opportunity to avoid this connection and impacts No additional wetlands or
buffers are impacted by the proposed project
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
Page9of13

USAGE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on January 15, 2002, mitigation will be required when
necessary to ensure that adverse effects. to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USAGE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete.
An applicant may also choose to review the current guidelines for stream restoration in DWQ's
Draft Technical Guide for Stream Work in North Carolina, available at
httu:/i h2o.enr .state.nc.us/ncwetlands%strn~~ridel-~tml.
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
The proposed impacts due to the road crossing is less than 150 feet therefore stream
mitigation is not required In addition all on-site Neuse Riparian Buffers have been placed
in open mace to be dedicated to the Town of Wake Forest or placed m a conservation
easement No other environmental features (wetlands and streams) have been impacted by
the ro osed develo ment.
2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement
Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at
[phone] to determine availability, and written approval from the NCEEP indicating
that they are will to accept payment for the mitigation must be attached to this form. For
additional information regarding the application process for the NCEEP, check the NCEEP
website at http•//h2o eau state.nc.us~v~-t~/index.lltm. If use of the NCEEP is proposed, please
check the appropriate box on page five and provide the following information:
Amount of stream mitigation requested (linear feet): 0
Amount of buffer mitigation requested (square feet): 0
Amount of Riparian wetland mitigation requested (acres): 0
Amount ofNon-riparian wetland mitigation requested (acres): 0

LEVEL SPREADER SYSTEM OPERATION AND MAINTENANCE AGREEMENT (1/2007)
A level spreader system includes: a forebay, diverter box, level spreader, riparian buffer/vegetated filter strip,
and flow bypass channel.
Name of Project: The Registry at Bennett Park 0 `1 - 1 ~1 S la y Z
Address: Intersection of West Holding Avenue and Richland Ridge Drive
Maintenance activities shall be performed as follows:
MAINTENANCE ACTIVITY FREQUENCY
Post-construction monitoring-inspect for vegetation, Check after every heavy rainfall for first 6 months
settlin ,erosion, or concentrated flow. followin construction.
Inspect Diverter Box and clean and/or make repairs. Once a month and after heavy rainfalls/storms.
Look for:
• Clogged inlet or outlet pipes.
• Trash/debris in the box.
Inspect Forebay + Level Spreader. Clean and/or Once a month and after heavy rainfalls/storms.
make repairs. Look for:
• Sediment in forebay and along level spreader
lip;
• Trash and/or leaf buildup.
• Scour, undercutting of level spreader.
• Settlement of level spreader structure (no
longer level; you see silt downhill below level
spreader).
• Fallen trees on level spreader.
• #57 stone washin downhill.
Inspect the Riparian Buffer and the Bypass Swale Once a month and after heavy rainfalls/storms.
and make repairs as needed'. Look for:
• Damaged turf reinforcement or riprap rolling
downhill.
• Erosion within the buffer or swale.
• Concentrated flows downhill of level
s reader-look for ullies or sediment flows.
Mow grass to a 6" height. As needed during growing season.
Remove any weeds/shrubs growing on level spreader Once a year.
or in swale.

Ms. Karoly,
Please find attached the information you requested in your letter dated December 20, 2007 and
received January 7, 2008. We would like to respond to your questions with the following
information:
1. The approval for the project from the Town of Wake Forest limited the impervious surface of
the site to 24%. The attached Staff Report from Chad Sary with the Town of Wake Forest
confirms the 24% limitation on the project (page 2).
2. Level spreaders are placed at both of the proposed stormwater outlets. The outlets are located
outside the NRRB. The attached plan sheets identify the location of the outlets and the detail
sheets provide further information on the construction of the level spreaders.
3. This does not apply since level spreaders are provided as outlined in #2 above.
Please let me know if you have any questions or comments. Thank you for your time and
consideration.
Sincerely,
Michael D. Allen, P.E.
