Redmond requires construction-phase erosion and sediment control BMPs on any ground disturbance over 2,000 sf under RMC Title 15 and the DOE Stormwater Manual, with daily inspection during wet season.
Redmond erosion and sediment control is implemented through Redmond Municipal Code Title 15 and the Washington Department of Ecology 2019 Stormwater Management Manual for Western Washington. Any land-disturbing activity over 2,000 square feet, or less in steep-slope and critical areas, requires a Construction Stormwater Pollution Prevention Plan (SWPPP) and best management practices such as silt fence, wattles, stabilized construction entrances, catch-basin inserts, and cover for stockpiled soils. During the wet season (October 1 through April 30), stabilization of disturbed soil within 2 days is generally required, and the wet-season rules are strictly enforced near the Bear Creek, Evans Creek, and Sammamish River corridors because of salmon habitat. Projects over 1 acre also require coverage under the state Construction Stormwater General Permit through DOE. Redmond inspectors routinely check sites after storm events and can issue stop-work orders for uncontrolled sediment.
