Technique Practice How it works When to apply Comments
Pre-construction planning Site planning and grading Minimizes soil disturbance and unprotected exposure Planning Expose only as much as needed for immediate construction
Sequencing Limits amount of soil exposed Planning
Resource protection Forest conservation and water resource buffers Establishes protective zone around valued natural resources Early Buffer variable from a few feet to 100 feet depending uopn resource being protected and local regulations
Perimeter control Access and egress control Minimizes transport of soil off-site Early Must be in place prior to commencement of construction activities
Inlet protection Stops movement of soil into drainage collection system Early
Slope stabilization Grade breaks Minimizes rill and gully erosion Early No unbroken slopes > 75 feet on 3:1 side slopes or greater
Silt curtain Stops sediment from moving Early
Runoff control Stabilize drainageways Minimizes increased erosion from channels All construction phases Possible to convert these into permanent open channel systems after construction
Sediment control basins Collects sediment that erodes from site before it leaves site or impacts resource All construction phases Possible to convert these into post construction practices after construction
Rapid stabilization of exposed soils Seeding and mulch Immediately established vegetative cover on exposed spoil All construction phases Apply seed as soils are exposed
Blankets Provides extra protection for exposed oil or steep slopes All construction phases Apply blanket as exposed soil cover until plants established
Inspection and maintenance Formalized I&M program Assures that BMPs are properly installed and operating in anticipated manner All construction phases Essential to proper BMP implementation
