Oak Park requires erosion and sediment control measures during construction and land-disturbing activities. Contractors and property owners must prevent soil, sediment, and construction debris from entering streets, storm drains, and neighboring properties. The village enforces MWRD watershed standards and IEPA NPDES requirements.
Erosion and sediment control is required for all construction, demolition, and grading activities in Oak Park. The village enforces requirements consistent with the Metropolitan Water Reclamation District (MWRD) Watershed Management Ordinance and the Illinois Environmental Protection Agency's NPDES General Permit for Stormwater Discharge from Construction Activities. Projects disturbing one acre or more require an NPDES permit and a Storm Water Pollution Prevention Plan (SWPPP). Even smaller projects must implement basic erosion control measures. Required measures include silt fencing around disturbed areas, inlet protection for nearby storm drains, stabilized construction entrances to prevent mud tracking onto streets, proper stockpile management, and timely revegetation of disturbed areas. Dewatering of excavations must be filtered or settled before discharge. Construction debris and washout water (particularly concrete washout) must be contained on-site. The village's building inspectors verify erosion control measures as part of site inspections during the permit process. Measures must remain in place until the site is fully stabilized with permanent vegetation or impervious surfaces.
Failure to install or maintain erosion controls can result in stop-work orders and fines of $100 to $750 per day. Discharging sediment-laden water into storm drains or onto neighboring properties is a separate violation. IEPA can impose additional penalties for NPDES violations.
