Re: Water Quality Certification Approval & Condition #6 Requirement
Rolesville High School (WCPSS-H6 Project)
Wake County, NC
To Ms. Higgins and Mrs. Gilleski:
On May 20, 2011, S&EC received a copy of the 401 Water Quality Certification and Authorization
Certificate Approval for the Rolesville High School project (DWQ #: EXP 11-0387). Condition #6
of this Approval required additional information to be submitted to your office. As such, please
see attached signed and notarized Operations & Maintenance Agreement for the bioretention
basin & vegetated filter strip/level spreader. Additionally, we have again included a copy of the
Letter of Conditional Stormwater Approval from Wake County; however copies of the Approved
Plans and calculations were submitted with the Pre-Construction Notification Application and
therefore should be referenced within the file.
We anticipate that this is all that the DWQ needs with regard to the Stormwater Management
Plan and Condition #6 of the written Water Quality Certification Approval. If you have any
questions or any additional explanation is needed, please don't hesitate to call.
Sincerely,
SOIL & ENVIRONMENTAL CONSULTANTS, PA

OPERATIONS AND MAINTENANCE MANUAL
ROLESVILLE HIGH SCHOOL BIO-RETENTION BASIN & VEGETATED FILTER
STRIP/LEVEL SPREADER
This manual establishes procedures for maintenance and operation of the Rolesville
High School Bio-Retention Basin and Vegetated Filter Strip/Level Spreader in
accordance with NC DWQ and Wake County guidelines and as set forth for the Town of
Rolesville, NC storm water management program.
BIO-RETENTION BASIN
MAINTENANCE
Vegetation-The drainage basin bottom and dam has a ground cover of Tifton Bermuda
419 sod, which if properly maintained will prevent erosion of the embankment and
provide an easy surface for inspection. The grass will be most difficult to retain in the
area subject to water level fluctuation. Make certain the grass is not "scalped" too low
when mown.
Re-Seeding-Periodic re-seeding may be required to establish grass on areas where
sod did not take or has been destroyed or have become bare. Before seeding, fertilizer
(12-12-12) should be applied at a minimum rate of 12 to 15 pounds per 1,000 SF. The
seed should be evenly sown at a rate of three pounds per 1,000 SF. The seed should
be covered with soil to the depth of approximately '/". Immediately following the
planting, the area should be mulched with straw and tacked into place with a
biodegradable slurry. If any area greater than 100 square feet is in need of repair,
Tifton 419 Bermuda Sod will be required, seeding will NOT be permitted.
Mowing-Grass mowing, brush cutting and removal of weed vegetation will be
necessary for the proper maintenance of the bio-retention area. All area slopes and
vegetation should be mowed when the grass exceeds 6" in height. Acceptable methods
include the use of weed whips or power brush cutters and mowers. Do Not cut lower
than 2" above grade.
Page 2 of 8
Erosion-Erosion occurs when the water concentrates causing failure of the vegetation
or when vegetation dies and sets up the environment for rill erosion and eventually
gullies from the stormwater runoff. The areas should be inspected as per the attached
schedule. Proper care of vegetative areas that develop erosion is required to prevent
more serious damage to the site. Rills and gullies should be filled with suitable loamy
sand soil compacted and then seeded. Methods described earlier on vegetation should
be used to properly establish the grass surface. Where eroded areas are detected, the
cause of the erosion should be addressed to prevent a continued maintenance problem.
Frequently, problems result from the concentration of runoff to one point of the bio-
retention area instead of a uniform distribution of runoff. This can be corrected by
reshaping, to more evenly distribute the runoff to areas not experiencing erosion
problems.
Rodent Control-Generally, rodents are not a problem. Rodents such as groundhogs,
muskrats and moles are attracted to moist, wet areas and can be quite dangerous to
structural integrity and proper performance of the earthwork and drainage. Groundhogs
and muskrats thrive on burrowing into the manmade earthwork, which become
pathways for seepage. In the event that burrows are detected within the bio-retention
area or dam, the rodents should be dealt with by legal removal and then repairs shall be
made.
Trash and Debris--Trash acts as a barrier to stormwater infiltration and attracts
unwanted pests. The bio-retention area should be kept clear of debris such as loose
bottles, cans, food containers and other forms of rubbish. The area should be cleared
of debris as needed, but no less than twice a year.
MAINTENANCE OF SPILLWAYS AND CONTROL STRUCTURE
Inspection of Conduits--Conduits should be inspected thoroughly once a year. Conduits
should be visually inspected at the joints. Pipes should be inspected for proper
alignment (sagging), elongation and displacement at joints, cracks, leaks, surface wear,
loss of protective coating, corrosion and blocking. Problems with conduits most often
occur at joints and special attention should be given to them during inspection. Joints
should be checked for gaps caused by elongation or settlement and loss of joint filler
material. Open joints can permit erosion of the earthwork and possibly the piping of soil
material through the joints. A depression in the soil surface over the pipe may be signs
that soil is being removed from around the pipe. DO NOT just fill this in with more earth
material. Excavate to locate the joint problem and correct that problem before
backfilling.
OPERATION
Sub-surface Drainpipes--Drainpipes should always be operable so that the water can be
drawn down in the event of severe rain or for repairs or maintenance. Using cleanouts
provided, power flush the system once each year to confirm there are no blockages or
disconnects. If repairs are required, backfill material in basin must be as originally
installed and specified.

VEGETATED FILTER STRIP/LEVEL SPREADER
MAINTENANCE
Vegetation-The vegetated filter strip has a ground cover of Tifton Bermuda 419, which
if properly maintained will prevent erosion of the ground surface from pipe outflow and
provide an easy surface for inspection. No woody species, volunteer species or weed
species are permitted within the filter strip area and shall be removed or sprayed with
herbicide as necessary.
Re-Seeding- Annually, the filter strip will be re-seeded with Tifton Bermuda 419 to
maintain a dense growth of vegetation, aerated (if necessary) and soil pH tested (add
lime if necessary).. Before seeding, fertilizer (12-12-12) should be applied at a
minimum rate of 12 to 15 pounds per 1,000 SF. The seed should be evenly sown at a
rate of three pounds per 1,000 SF. The seed should be covered with soil to the depth of
approximately'/". Immediately following the planting, the area should be mulched with
straw and tacked into place with a biodegradable slurry. If any area greater than 100
square feet is in need of repair, Tifton 419 Bermuda Sod will be required, seeding will
NOT be permitted.
Mowing- Two to three times a year, grass filter strip will be mowed and the clippings
harvested to promote the growth of thick vegetation with optimum pollutant removal
efficiency. Turf grass should not be cut shorter than 2 inches and may be allowed to
grow as tall as 12 inches. Make certain the grass is not "scalped" too low when mown.
Grass mowing, brush cutting and removal of weed vegetation will be necessary for the
proper maintenance of the filter strip area. All area slopes and vegetation should be
mowed when the grass exceeds 12" in height. Acceptable methods include the use of
weed whips or power brush cutters and mowers. Do Not cut lower than 2" above grade.
Erosion-Erosion occurs when the water concentrates causing failure of the vegetation
or when vegetation dies and sets up the environment for rill erosion and eventually
gullies from the storm water runoff. The areas should be inspected as per the attached
schedule. Proper care of vegetative areas that develop erosion is required to prevent
more serious damage to the site. Rills and gullies should be filled with suitable loamy
sand soil compacted and then seeded. Methods described earlier on vegetation and re-
seeding should be used to properly establish the grass surface. Where eroded areas
are detected, the cause of the erosion should be addressed to prevent a continued
maintenance problem. Frequently, problems result from the concentration of runoff to
one point instead of a uniform distribution of runoff. This can be corrected by reshaping,
to more evenly distribute the runoff to areas not experiencing erosion problems.
Rodent Control-Generally, rodents are not a problem. Rodents such as groundhogs,
muskrats and moles are attracted to moist, wet areas and can be quite dangerous to
structural integrity and proper performance of the earthwork and drainage. Groundhogs
and muskrats thrive on burrowing into the manmade earthwork, which become
pathways for seepage. In the event that burrows are detected within the filter strip/level
spreader area, the rodents should be dealt with by legal removal.
Page 4 of 8
Trash and Debris--Trash acts as a barrier to storm water infiltration and attracts
unwanted pests. The filter strip/level spreader area should be kept clear of debris such
as loose bottles, cans, food containers and other forms of rubbish. The area should be
cleared of debris as needed, but no less than twice a year.
MAINTENANCE OF LEVEL SPREADER STRUCTURE
Inspection of Levels Spreader Structure--The concrete level spreader structure should
be inspected thoroughly once a year. The structure shall be visually inspected at the
joints, ends and checked for level. Problems with concrete level lips most often occur
at joints and special. attention should be given to them during inspection. Joints should
be checked for gaps caused by expansion or settlement and loss of joint filler material.
Open joints can permit erosion of the earthwork. The intent is to have a level flow of
water over the concrete structure. If joints, cracks or settlement occurs, then repairs will
be required to ensure an even flow of water over the level spreader structure per the
original design.
Blind Storage Swale--Inspect area behind concrete level spreader structure. Area
should be clear of all vegetation, trash, weeds and sediment. If area is clogged with
sediment, remove layer of sediment and replace with clean stone per the original
design.
Outlet Pipe to Blind Swale--Inspect pipe entering blind swale for blockage, debris and
erosion. If any of these conditions are present then repairs as necessary shall be
made.
RECORD KEEPING
Operation of bio-retention area and vegetated filter strip/level spreader should include
recording of the following:
Annual Inspection Reports--A collection of written inspection reports should be
kept on record, see Inspection Form in this manual. Inspection should be
conducted annually. Copies should be provided to the Town of Rolesville and
Wake County Environmental Services - Flood and Storm Water Section.
Observations--All observations and corrective actions should be recorded.
Where periodic inspections are performed following significant rainfall, these
inspections should be logged into the Inspection Form of this manual.
Maintenance--Written records of maintenance and/or repairs should be recorded
on the Inspection Form of this manual.
Other Operational Procedures--The owner should maintain a complete and up-to-date
set of plans (as-built drawings) on-site and all changes made to the bio-retention area
over time should be recorded on the as-builts.

Dear Mr. Desmoreaux:
The above-referenced stormwater management plan has been reviewed and conditionally approved for the
addition of 23 acres of impervious cover for the project. The project shall provide peak flow and nitrogen
control through a bio-retention basin. The stormwater improvements and all conditions of approval must be
completed and approved by Wake County prior to final signoff of the Certificate of Occupancy (C.O.) for
your building permit. It is very important that your contractor, engineer and yourself be aware of these
additional provisions to insure that the outstanding stormwater management requirements are submitted,
reviewed, approved and installed, such that these conditions are satisfied. Items required prior to building permit
approval are listed below.
Maintenance Plan: The developer must record and reference a maintenance plan that instructs
the property owner about the annual maintenance tasks and associated costs for at least a 20-year
period. It will be the responsibility of the property owner to update the maintenance plan at least
every 10 years.
2. Maintenance Agreements: The developer must record, and reference a maintenance agreement
that sets forth the property owner's continuing responsibilities for maintenance. The Stormwater
Agreement document shall be completed and recorded; the agreement shall be cross referenced
with the easement plat.
3. Maintenance Easements: The developer must record easements for access, maintenance and
inspections by Wake County Government. The record plat shall indicate the boundaries of each
BMP, label the type of BMP and indicate the boundary of a 20' access and maintenance
easement.
4. As Built Plans: Upon completion of required improvements, the developer or the developer's
representative must submit an as-built survey of the required stormwater improvements to the
Rolesville high School
SW Approval
April 27, 2011
Page 2 of 2
Wake County Department of Environmental Services. This survey shall indicate whether
stormwater improvements were constructed in accordance with the County approved stormwater
plan.
Additional Plat requirements: Plat should show and call out the entire project area used in
storm water calculations. Any future development not related to the school will require an
amendment to this plan as well as a new storm water permit for the new developed area. Final
plat submittal must also be in accordance with the attached Final Plat Submittal document as
applicable.
Finally, there is a Stormwater Permit Fee of $ 24,250.00 and a Stormwater Review Fee of $ 24,250 to
be paid to Wake County. Please contact Lori Gorman of the WCPSS (919-857-9692) Email
lgorman ,wcpss.net for remittance of these fees to Wake County. Your memo should reference your
Stormwater Permit # S 2528.
This request for Wake County to evaluate a stormwater management plan does not relieve the applicant
from their responsibility to meet all applicable State and Federal Laws, including, but not limited to
necessary approvals from Federal Emergency Management Area Flood regulations/requirements,
Division of Water Quality stormwater or other water quality regulations/requirements, U.S. Army Corps
of Engineers Article 404/401 (Wetlands/Streams) jurisdiction/requirements, and/or any Federal, State,
County and Local municipal regulations or permit requirements. The approval issued in this letter cannot
supersede any other required permit or approval.
If you have any questions about this approval please call me at [phone].
Sincerely,
611??
