Kent requires Temporary Erosion and Sediment Control (TESC) plans for construction projects disturbing 7,000 sf or more per state rules. Silt fencing, cover, and stabilized entrances are standard.
Erosion control in Kent follows the Washington Department of Ecology Construction Stormwater General Permit and Kent Public Works standards. Sites disturbing 7,000 sf or more, or 1 acre for the state general permit, must submit a Temporary Erosion and Sediment Control plan with standard BMPs including silt fencing along the downgradient perimeter, stabilized gravel construction entrances, inlet protection at catch basins, mulched or hydroseeded slopes, and concrete washout containment. During the wet-season months (October to April) stricter rules require all exposed soil to be mulched or covered within 2 days, not 7. Sites near Mill Creek, the Green River, or steep-slope critical areas (above 15 percent) may need additional buffer maintenance and geotechnical oversight. Violations of erosion control are quickly enforced by Kent inspectors because sediment entering drainage ditches creates downstream flood and water quality issues.
