Construction Site Impact Reduction (Temporary Practices) Brush bar-
rier, construction entrance/exit, construction sequence, silt fence
(filter fence), storm drain inlet protection, straw bale barrier, tempo-
rary seeding, topsoiling.
Source Reduction Animal waste collection, bedding, chiseling, cisterns
used to harvest water, concrete grid, modular and porous paving,
curb elimination, debris removal, drain blockers, education programs,
exposure reduction, green roofs, landscape management controls,
minimization of pollutants, parking lots and street cleaning, protect-
ing storm drain from hazardous waste deposition.

Erosion Control Contouring, strip cropping, conservation tillage, ter-
racing, channel vegetation, check dam, concrete block revetment,
critical area planting, erosion control blanket, gabions/gabion revet-
ment, grade stabilization structure, grassed waterway, level spreader,
lined waterway, low wall/slopeface plantings, mulching, netting and
matting, native revegetation, sheet flow dispersion, sodding, stone
revetment, terracing, water bar.
Water Volume Management Detention basin, dispersion trench, diver-
sion channel, diversion structure (flow splitter), dry well, exfiltra-
tion/infiltration, infiltration trench, isolation/diversion structure,
off-line infiltration system design, parking lot perimeter, infiltration
trench, parking lot storage, small infiltration basin, storm water reten-
tion pond, wetland animal habitat design.

Water Quality Treatment and Constituent Entrapment (Vegetative and/or
Structural) Basic biofiltration swale, bioretention system, combined
infiltration/detention basin, compost filter system, constructed wet-
land, detention devices for dry/wet ponds, dry extended detention
ponds, dry swale, filter strips, median strip infiltration trench, off-line
infiltration basin, oil/grit separator, oil/water separators, organic
sand filter, peat sand filter, perimeter sand filter, pocket sand filter,
reversed elevation systems for parking lots and planting areas, ripar-
ian forest buffer, roadway landscape treatment system, sediment basin
(water quality enhancement), side-by-side infiltration basin, surface
sand filter, underground sand filter, underground trench with oil/grit
chamber, under-the-swale infiltration trench, water quality volume
storage tank, wet biofiltration swale, wet pond design, wet swale.

More Commonly Used BMPs
Riparian Buffers Limit sedimentation and erosion, provide shade, con-
tribute woody debris for stream health, incorporate floodways, and
allow natural stream channel movement. Buffers provide connecting
corridors, allowing wildlife to move safely. By slowing down water, buf-
fers enhance sediment deposition and reduce soil erosion. They also
