OPERATION AND MAINTENANCE AGREEMENT
I will keep a maintenance record on the Bioretentin Cell (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 r replaced immediately. These
deficiencies can affect the integrity of structures, safety of the public, and the
pollutant removal efficiency of the BMP.
1. General
A. During each inspection of the stormwater drain ge system, the attached checklist
shall be completed and filed with other maint ,nance records for the stormwater
drainage system.
B. The vegetated areas shall be maintained to keep a dense and healthy grass cover.
Grassed areas shall be mowed according tc the season while maintaining a
minimum height of 2 inches and a maximum he ght of 4 inches. The Bermuda Sod
shall not be fertilized but watered as needed tc maintain the grass in an optimum
condition.
C. All storm drainage pipes and structures shall at gall times remain clear and clean of
litter, leaves, debris, and silt.
D. The bioretention cell shall be inspected after all major storms. A major storm is a
rain even which produces 1 inch or more duri�g any 24 hour period of time. If
stormwater from a major storm is not draining after 48 hours, remove debris
blocking any inlet or outlet structures and any tither areas of clogging. Wash out
the underdrain system. t
E. Snow, mulch or any other material shall nev r be piled on the surface of the
bioretention cell.

F. Heavy equipment shall never be driven over the surface of the bioretention cell.

H. Once a year, a soil test of the soil media sh1 II be conducted and the results
provided in the required annual inspection repo to the Town of Wake Forest.

I. All components, devices and structures of the stormwater drainage system shall
be maintained in proper working condition at al times. Repair and replacement of
components shall meet the original design spe ifcations.

5. Annually
A. The bioretention cell and stormwater pipe sy em shall be thoroughly inspected
once a year by a qualified North Carolina F Iegistered Professional Engineer,
Registered Landscape Architect or Registered Professional Land Surveyor. This
inspection is required per the Town of Wake F rest UDO Code Section 12.5.6.E,
and a written report is due on the anniversary lispection
the issuance of the Certificate of
Occupancy. A copy of the annual inspectionnd maintenance records shall be
submitted to the Town of Wake Forest Engineeng Department. The report should
be sent to 301 South Brooks Street, Wake IF rest, NC 27587, Attn: Director of
Engineering. All deficiencies identified in the report shall be corrected
within thirty (30) days.
B. Once a year, a soil test of the cell media shall `be conducted. If the cell media is
not in compliance with the original design and s clogged then the media shall be
replaced. When replacing the cell media the k the No. 57 washed stone layer
and underdrain system below the cell media E nd remove any sediment material
that may cause clogging. The old cell media hall be disposed of in a landfill in
compliance with current Federal, State and Lo 1 regulatory requirements.
C. Visually inspect pipes for proper alignment, sag ing, elongation & displacement of
joints, cracks, leaks, surface wear and blockage. Most problems occur at the joints
where gaps develop from settlement or elongation & loss of joint sealant 1 filler
material. Pipes should also be checked for s Igns of water seeping along their
exterior surface. A depression in the surface over the pipe may be a sign that soil
is being washed around the pipe. Effective rep it of the internal surface or joint of
a conduit is often difficult, even hazardous, anto should not be attempted without
appropriate professional supervision.
D. Perform all required maintenance for the Semi-�nnual inspection.
