BMP Element Frequency Problem
Yes
Corrective Action
or No?
Channel
Annually
Debris and sediment build-up is
present at the top of the filter strip
or other landsca
in
.
Check the tributary flows for trouble
spots and correct any problems
immediately. Manually remove buildup.
Gravel
diaphragm
Every two
years
Foot or vehicular traffic is
compromising the gravel diaphragm.
Create to block traffic. Re-stabilize
immediately.
Level Spreader
Twice per
year
Level spreader is not performing
properly. Flows are concentrating on
the outflow side of the element.
Search the spreader for chips, cracks, or
any other fundamental compromise of
the structure. Immediately repair.
Vegetation
Monthly
Vegetative density is less than 90%
cover in the boundary zone or grass
filter.
Reseed and fertilize (if necessary)
exposed soil.
Plant composition consistent with
approved plans.
Presence of invasive species/weeds
Dead vegetation/exposed soil
Outlet
On-going
Outlets provide stable conveyance out
of facility.
Excessive trash/debris/sediment
accumulation at inlet
Evidence of erosion at/around inlet
Overall
On-going
Maintenance access to facility
Condition of structural components
Condition of hydraulic control
components
Excessive trash/debris/sediment
Evidences of erosion
Evidence of oil/chemical
accumulation
Evidence of standing water; ponding,
noticeable odors, water stains,
presence of algae or floating aquatic
vegetation
Complaints from local residents
Mosquito proliferation
Encroachment on facility or easement
by buildings or other structures
Once established, filter strips have minimal maintenance needs outside of the Spring clean up: regular mowing, repair of
check dams and other measures to maintain the hydraulic efficiency of the strip and a dense, healthy grass cover. Grass
filter strips and boundary zones of conservation filter strips must be mowed at least twice a year to prevent woody
growth.
