Watershed Management Ordinance and Infiltration/Inflow
Watershed Management Ordinance (WMO)
The Watershed Management Ordinance (WMO) applies to all development within the boundaries of Cook County, Illinois, and qualified sewer construction within the MWRD’s corporate boundaries or service agreement areas. Components which are regulated under the WMO include qualified sewer construction, drainage and detention, volume control, floodplain management, isolated wetland protection, riparian environment protection, and soil erosion and sediment control. The WMO went into effect on May 1, 2014.
The WMO Stormwater Management Report provides the cumulative progress of the implementation of the WMO, including the number of permits issued, the number of acres developed/redeveloped, and the total volume control storage, detention storage and compensatory storage approved under WMO permits.
