Wetland Restoration & Preservation Plan (WRAPP)
WRAPP Given the Green Ribbon Award
The Friends of the Chicago River honored the SMC with a Green Ribbon Award for the Wetland Restoration and Preservation Plan at the Big Fish Ball and Chicago River Blue Awards annual event on June 1, 2022. The Green Ribbon Award recognizes projects that demonstrate a high level of river-sensitive design and consideration. Accepting the award on behalf of SMC were Mike Prusila (WRAPP project manager) as well as Glenn Westman and Juli Crane (Principal Wetland Specialists). SMC appreciates the support and effort of all who participated in developing the WRAPP, especially the members of our Technical Advisory Group. We look forward to folks using the WRAPP to identify some great projects within our County.
The WRAPP was funded through a USEPA Region 5 Wetlands Program Development Grant.
SMC classified 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 is the foundation for the assessment of wetland function and provides a basis for comparison of wetlands across the County.
Functional Assessment and Examples of Wetland Functions
Wetland functions are properties that a wetland performs naturally. Typically, they relate to a physical and/or biological process. Sometimes, functions are linked to processes within other habitats connected to the wetland or water body. Functions may have economic, social, or cultural benefits to humans or provide environmental or ecological value. Not all wetlands perform all functions, nor do they perform all functions equally well.
The WRAPP assesses 13 functions (services) as selected by a Technical Advisory Group (TAG). The TAG also rated the level to which an existing wetland performs each function compared to other wetlands in the County. The WRAPP estimates the degree to which functions are performed by existing wetlands, and it estimates the degree to which functions might be restored for potentially restorable wetlands.
The following table identifies the 13 wetland functions assessed in the WRAPP.
|Hydrologic Functions||Biodiversity Functions||Water Quality Functions|
|Flood Water Storage||Native Fish Habitat||Carbon Sequestration|
|Stream Baseflow Maintenance||Unique Wetland Resources||Nutrient Transformation (P-focus)|
|Stream Shading||Sediment and Other Particulate Retention|
|Waterfowl Habitat||Shoreline/Stream Bank Stabilization|
|Wetland-dependent Bird Habitat (Other)|
|Wildlife Movement Corridors|
|Woodland Amphibian Habitat|
Technical Report & Decision Support Tool
The Technical Report (Volume 1) and Appendices (Volume 2) describe WRAPP development and methodology and summarize its findings. The Decision Support Tool is an online mapping application that allows users to view the WRAPP results in an interactive environment.
