The Lake County Watershed Development Ordinance (WDO) Permit is required when a project is located in a floodplain or flood-prone area; may impact a wetland; will hydrologically disturb more than 5000 square feet; or will modify the site drainage.
Flood Insurance Rate Maps
The Federal Emergency Management Agency (FEMA) publishes Flood Insurance Rate maps, or FIRMS, that depict floodplain boundaries. Further explanation of this information is available on the FEMA website.
Stormwater Management Commission
The Lake County Stormwater Management Commission (SMC) was established in 1991 through state legislation to coordinate stormwater management activities from a countywide and interjurisdictional perspective. The main components of their program are:
Flood damage reduction through flood hazard mitigation projects, and implementing best management practices (BMPs), watershed management plans and effective floodplain and stormwater management regulations
Managing Lake County's floodplains and watersheds by administering countywide floodplain and stormwater management standards
Natural resource protection and restoration by utilizing a mix of funding sources and partnerships to restore and enhance the natural drainage system
