PROPOSED BID RECOMMENDATION
Department: Resource Management
Request: Authorization for the Forest Preserves of Cook County (the "Forest Preserves") to enter into a construction contract with CPMH Construction, Inc., Chicago, Illinois for drainage improvements at Eggers Marsh.
Reason: Contract #74000005477 issued under Project #18-31-106R consists of construction to replace failed stormwater infrastructure controlling drainage of the Eggers Grove wetland complex.

Hemi-marsh is a type of wetland habitat characterized by a ratio of open water and emergent aquatic vegetation that is favorable for migratory birds and amphibians.
The hydrologic recovery plan being implemented was developed by a consultant as part of a 2014 grant awarded to the Forest Preserves through the Illinois Department of Natural Resources Coastal Management Program. Additionally, the project will be partially funded through a $100,000.00 grant sub-awarded to the Forest Preserves by The Nature Conservancy via the National Fish and Wildlife Foundation, the receipt of which was approved by the Board of Commissioners on 12/13/2016.
