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
