Colorado Construction
Stormwater Inspections
Colorado's COR400000 permit is administered by the Colorado Department of Public Health and Environment and applies to construction activities disturbing one or more acres. The permit requires a Stormwater Management Plan (SWMP) and places emphasis on maintaining BMPs throughout the project lifecycle. Colorado's semi-arid climate and sensitive mountain watersheds require particular attention to erosion control during snowmelt and summer storm events.
