Tinley Park is subject to the Metropolitan Water Reclamation District of Greater Chicago (MWRD) Watershed Management Ordinance (WMO), which regulates stormwater detention, volume control, floodplain, and wetland impacts. Development disturbing 0.5 acres or creating significant impervious surface triggers WMO permit review. The Village enforces local stormwater standards and illicit discharge prohibitions.
Tinley Park falls under the MWRD Watershed Management Ordinance (effective May 1, 2014, with subsequent updates), which governs stormwater management throughout Cook County. The WMO requires stormwater detention for development creating 0.5 acres of hydrologically-disturbed area or meeting other trigger thresholds, with detention release rates limited to 0.15 cfs per acre for 100-year events. Volume control standards require capture and retention of the first 1 inch of runoff from new impervious surface. Floodplain and wetland impacts trigger additional permitting. Tinley Park as the local municipality reviews WMO compliance for most projects and issues a Village stormwater permit tied to WMO approval. Projects in regulatory floodplain along Tinley Creek and tributaries require additional floodplain development permits and compliance with FEMA flood insurance rate map base flood elevations. The Village's MS4 (Municipal Separate Storm Sewer System) National Pollutant Discharge Elimination System permit prohibits illicit discharges of anything other than stormwater into the storm sewer system. Residents should not wash cars into storm drains, dump motor oil or paint into drains, or let grass clippings enter drainage swales.
Unpermitted development triggering WMO review results in stop-work orders, mandatory detention/volume control retrofits, and fines. Illicit discharges into the storm sewer system violate the Village's MS4 permit and may result in fines from $75 to $750 per day and EPA enforcement. Code Enforcement: (708) 444-5100.
