Loveland, CO Environmental Rules: Erosion Control (2026)

Erosion control on Loveland construction sites is enforced under LMC Chapter 13.20 and the Loveland Storm Drainage Criteria (LSDC), an addendum to the Mile High Flood District (MHFD) Urban Storm Drainage Criteria Manual. Every site — public or private, residential or commercial — must implement temporary BMPs adequate to prevent sediment, concrete washout, fuels, and other pollutants from leaving the property. Required BMPs per MHFD Vol. 3 Ch. 7 typically include silt fence at the down-gradient site perimeter, wattles, vehicle tracking control (VTC) pads at every site egress, inlet protection on adjacent storm drains, stabilized stockpiles, concrete washout containment, sediment traps and ponds, dewatering structures, rip rap, and erosion control mats, plus prompt seeding or mulching of disturbed areas. Sites of 1/2 acre or more need a city Stormwater Quality Permit and a Stormwater Management Plan (SWMP) reviewed by the Stormwater Utility Division. Sites of 1 acre or more must also enroll in the State CDPS Stormwater Construction Permit administered by CDPHE under the Colorado Water Quality Control Act and maintain the SWMP on site for inspection. Failure to install BMPs before ground disturbance is one of the most common Stop Work triggers issued by the city.
