RE: O'Reilly Auto Parts HWY 64 Road Widening
Cyndi,
Following are our responses to your review comments dated July 24, 2008. After recognizing
that a wet pond is not meant to service a site as small as this one I received verbal approval
from Joseph Gyamfi to substitute an open basin sand filter for the wet pond and grass swale
that was previously submitted. Although the grass swale remains as a conveyance we are no
longer seeking nutrient removal credit for it.
Additional Information Requested
Wet Pond (Changed to Open Basin Sand Filter w/ Forebay)
a. The correct supplement form for a sand filter has been filled out and stage storage
calculations have been added to sheet 19.
b. Required items checklist for a Sand Filter has been completed and is attached.
c. A cross section of the new sand filter is provided on sheet 19 along with flow splitter
device details and all related calculations.
d. No planting plan is required for the sand filter.
e. In lieu of a soil report we have designated that a clay liner be installed under and around
the sand filter which should give the same benefit for this device that it would have
given the wet pond.
f. There is no outlet structure in the new sand filter (Over flow is handled by the flow
splitter at the head of the forebay.)
2. Grass Swale (Now utilized for conveyance only)
a. The required items checklist for a grassed swale is no longer relevant since all nutrient
removal is being handled through sand filter.
b. The maximum velocity of flow in the swale is acceptable for a conveyance with no
nutrient removal.
c. A cross section of the grass conveyance swale has been added with pertinent details.

Sand Filter 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.
Important maintenance procedures:
- The drainage area will be carefully managed to reduce the sediment load to the
sand filter.
- Once a year, sand media will be skimmed.
- The sand filter media will be replaced whenever it fails to function properly after
vacuuming.
The sand filter will be inspected quarterly 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 will be kept in a known set location and will be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall be
repaired immediately.

Abstract:
This is an existing 2.06 acre site. There will be a right-of-way dedication of 0.04 acres at the
intersection of New Bern Avenue and Raleigh Beach Road. This will leave a net site area of
2.02 acres.
The existing site stormwater drains to the west corner of the site to the intersection of New Bern
Avenue and Raleigh Beach Road.
For the new development stormwater detention will be required to restrict the peak post-
development stormwater discharge to the pre-development rate of flow. The detention will be
provided with the use of an above ground dry detention pond with a restrictor opening in the
riser structure in the bottom of the pond. The post development stormwater discharge has been
divided into two drainage areas. Area A is the lower undeveloped portion of the site. The
stormwater discharge from this area is un-detained. Area B is the portion of the site being
developed and this discharge will be captured and detained in above ground detention pond.
The stormwater routing calculations were performed using Hydra Flow Hydrographs to satisfy
the City of Raleigh requirements for stormwater detention.
Findings
Peak Discharge Reduction for the 2 and 10 Year Storm
Pre-Development
Q2 = 3.37 cfs
Q,o=4.23cfs
Post-Development (Un-detained)
Q2 = 6.28 cfs
Q,a=7.88cfs
Post-Development (Detained in Above Ground Dry Detention Pond)
Q2 = 3.34cfs
Q,o = 4.13 cfs
Nitrogen Reduction Calculations
Nitrogen reduction measures are required for this development by NC DWQ. The nitrogen
reduction will be achieved with the use of an Open Basin Sand Filter with Forebay. A 35% TN
removal is provided with this structure. The Open Basin Sand Filter is designed to handle the
first inch of rainfall over the drainage area. A Flow Splitter Storm structure will be utilized to
divert the amount of stormwater discharge over the one inch rainfall event directly into the
above ground detention pond.
Conclusions
The site meets the City of Raleigh's requirements for peak discharge and nitrogen reduction.
