OPERATIONS AND MAINTANENCE MANUAL
CAMBERLY ESTATES SUBDIVISION STORMWATER CONSTRUCTED WETLAND AREA
This manual establishes procedures for maintenance and operation of the Camberly Estates
Subdivision constructed wetland area(s) in accordance with Wake County guidelines as set forth
in the UDO.
MAINTAINENCE OF CONSTRUCTED WETLAND AREAS
Vegetation- The drainage areas have ground cover of wetland plantings outside of the ponding
area, which if properly maintained will prevent erosion of the embankment and provide an easy
surface for inspection. The grass will be most difficult to obtain in the area subject to water
level fluctuation, and has been planted above the inundated areas. Grass should be fertilized
every October and April. Wetland plants are located within all water level fluctuation areas.
Check vegetation conditions within all water level fluctuation areas. Check vegetation
conditions within the constructed wetland area and replace if necessary any damaged plant
materials.
Re -seeding- Periodic re -seeding may be required to establish grass on areas where seed did not
take or have been destroyed. 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 covered to the depth of
approximately %". Immediately following the planting, the area should be mulched with straw.
Trees and Shrubs- Trees, shrubs and other landscape vegetation should be permitted only as
shown on the approved planting plan. The vegetation should be kept healthy and vibrant. If a
tree or shrub dies it should be replaced with another tree or shrub from the same species (see
attached maintenance schedule).
Mowing- Grass mowing, brush cutting and removal of weed vegetation will be necessary for
the proper maintenance of the areas. All area slopes and vegetation should be mowed when
the grass exceeds 8" in height. Acceptable methods include the use of weed whips or power
brush cutters and mowers.
Erosion- Erosion occurs when the water concentrates causing failure of the vegetation or when
the vegetation dies and sets up the environment for rill erosion and eventually guiles from the
storm water runoff. The areas should be inspected. Proper care of vegetative areas that
develop erosion is required to prevent more serious damage to the site. Rills and guiles should
be filled with suitable 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
constructed wetland 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 in this urban environment, 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 constructed wetland
area, the rodents should be dealt with by removal.
Trash and Debris- Trash acts as a barrier to storm water infiltration and attracts unwanted
pests. The constructed wetland 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 CONTRIL 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 o 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.
OPERATION
Drainpipes- Drainpipes should always be operable so that the water can be drain down in the
event of severe rain or for repairs or maintenance.
Record Keeping- operation of constructed wetland area should include recording the following:
Annual Inspection Reports- A collection of written inspection reports should be kept on
record in Section IV of this manual. Inspection should be conducted annually. Copiers
should be provided to the City of Raleigh storm water management section of the
engineering department.
Observations- All observations should be recorded. Where periodic inspections are
performed following significant rainfall, these inspections should be logged into the
Periodic Inspection, Operations and Maintenance Form in Section IV of this manual.
Maintenance- Written records of maintenance and/or repairs should be recorded on the
Periodic Inspection, Operations and Maintenance Form in Section IV of this manual.
Other Operational Procedures- the owner should maintain a complete and up-to-date set of
plans (as -built drawings) and all changes made to the constructed wetland area over time
should be recorded on the as-builts.

Sedimentation and Dredging- sedimentation from on-site and off-site soils will eventually
result in the clogging of the drainage conduits and will have to be removed. The frequency of
this sediment removal can be reduced by the ensuring that the site areas around the building
be stabilized with a vegetative ground cover such that it restrains erosion. This would include a
periodic application of fertilizer and/or other treatment necessary to promote a stable
groundcover and minimize sedimentation to the pond. The removed material should be hauled
offsite to a suitable landfill site or mounded somewhere on site and stabilized with a ground
cover sufficient to restrain erosion.
