Summary of temporary construction sediment control techniques
Link to this table
| 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 |
