Fountain, CO Environmental Rules: Erosion Control (2026)

170 sets the rule: no land area in Fountain can be graded, stripped, excavated, filled, or disturbed without a grading permit from the city engineer, and every development or construction plan submitted for approval must carry a soil erosion/dust control plan prepared to the city's Best Management Practices manual. Once work starts, operators must maintain acceptable erosion and sediment control BMPs matching the manual's technical standards. The section adds specific field duties: stormwater leaving a construction site cannot cause or threaten pollution of state waters; concrete washout water cannot be discharged to any drainage system; building materials, waste, or debris cannot sit in a street or alley outside an approved traffic control plan; vehicle tracking of soil off site must be minimized; and the contractor is responsible for removing sediment and debris that accumulates in the city's storm sewer as a result of the work.

Operators must comply with the Colorado Water Quality Control Act, the city's MS4 discharge permit, and federal Clean Water Act permitting on top of the local plan. A copy of the stormwater management plan (SWMP) must be filed with the city engineer and kept on the construction site until the work is accepted. This section was last amended by Ordinance No. 1450 in 2009, adding the low-impact development BMP requirements for new development and redevelopment, on top of the original 2006/2007 grading and erosion text.
