Grand Junction, CO Environmental Rules: Erosion Control (2026)

Grand Junction Municipal Code § 13.28.030(a) requires all covered development to provide on-site erosion and sediment control, illegal-discharge control, and runoff collection consistent with the City's Stormwater Management Manual. Under (a)(2), any owner whose project disrupts or exposes soil or removes vegetation on one acre or more during the life of the project must obtain a State discharge permit and use specific best management practices (BMPs) adopted by the City. Subsection (a)(5), Erosion and Sediment Control, requires BMPs to prevent sediment release, minimizes disturbed areas, and requires disturbed soil, including at site entrances and exits, to be managed to prevent tracking, blowing and fugitive emissions; sediment, dirt or mud tracked onto public streets must be removed immediately by sweeping, scooping or shoveling at the owner's expense, and if not removed within the time stated in a City notice, the City or its contractor removes it and bills the property owner, with unpaid costs becoming a property lien.

Section 13.28.030(b) requires a written construction storm water management plan, reviewed and approved by the Community Development Department before construction starts, for any project (including phased common plans of development) disturbing one acre or more; the plan must be prepared under a qualified person per (c), and under (d) the owner must inspect all BMPs at least once every 14 days and after any precipitation or snowmelt event causing erosion, correcting major modifications within seven calendar days of an inspection showing they are needed. Post-construction, permanent BMPs must be maintained in good working condition for the life of the development under (e), and a qualified person must certify compliance before a certificate of occupancy issues under (f).
