The Lake County Watershed Development Ordinance (WDO) regulates new development including government projects, residential, commercial and industrial development, public roads as well as some home additions and the redevelopment of existing sites. New development meeting one or more of the following criteria for typical development will need a Watershed Development Permit. There are instances where a development may be exempt from certain portions of the WDO.
Typical Development Requiring a Watershed Development Permit
The project is in a floodplain or a floodprone area
If you are developing in a Non-Certified Community (PDF), SMC is the WDO permitting agency. You are strongly encouraged to set up a pre-application meeting with SMC by calling 847-377-7700.
The Watershed Development Permit is usually separate from a local building permit. However, a Certified Community may have included the Watershed Development Permit within its own current site development or building permit procedures, so check with the community.
