Wetland Restoration & Preservation Plan

Project Overview
The Lake County Wetland Restoration and Preservation Plan ("WRAPP") will identify and assess the functional significance of existing, historic, and potentially restorable wetlands in Lake County, Illinois. The WRAPP report and interactive online planning tool will include data available to the development, environmental, and government sectors and the general public as well.

This information can be used to guide planning decisions throughout the County and provide a basis for prioritizing wetland restoration and preservation efforts based on specific "wetland functions" (e.g., flood protection, water quality, wildlife habitat, etc.). Preserving existing wetland functions will help retain many important green infrastructure benefits.

The WRAPP is funded through a USEPA Region 5 Wetlands Program Development Grant. Project updates will be posted.

Wetland Classification
The current Lake County Wetland Inventory (LCWI) map will be refined to reflect changes that have occurred since the last LCWI update. SMC staff will classify wetlands based on the Landscape, Landform, Waterbody, and Water Flow Path (LLWW) hydrogeomorphic wetland classification scheme developed by the U.S Fish and Wildlife Service. This classification will be the foundation for the assessment of wetland function and provide a basis for comparison of wetlands across the County.

Functional Assessment
A Technical Advisory Group will convene to determine the functions (services) Lake County wetlands provide and the degree to which each function is performed, relative to other wetlands in the County​​​​. ​​

Examples of Wetland Functions
  • Floodwater storage
  • Surface water quality improvement
  • Groundwater recharge
  • Aquatic and wildlife habitat
  • Recreational and aesthetic benefits for communities
The outlined areas are identified as wetlands in the Lake County Wetlands Inventory. The two wetlands in green are clearly different from those in the pink and also from one another, and likely provide different wetlands functions. The WRAPP will provide information on the functions of individual wetlands.

Field Verification
Field verification of the functional assessment data will be conducted at several wetlands to confirm and calibrate the functional assessment methodology. The TAG will assist in developing the methods for the field verification.

Summary Report & Online Planning Tool
The information will identify opportunities for preserving, restoring and enhancing wetlands to maintain and increase wetland function. Both products will be available to the development, environmental and government sectors, and the general public.
