About the Permit

The Lake County Watershed Development Ordinance (WDO) Permit is required when a project is located in a floodplain or floodprone area; may impact a wetland; will hydrologically disturb more than 5000 sq. ft.; or will modify the site drainage.

If you are developing in a Certified Community, the municipality is the permitting agency.

If you are developing in an unincorporated area, Lake County Planning, Building and Development (PB&D) is the permitting agency. Contact Mea Blauer, PB&D, 847.377.2333.

If your project is not within a Certified Community or in an unincorporated area, SMC is the permitting agency for Non-Certified Communities.
