The Delaware Department of Transportation (DelDOT) has submitted a Prospectus to establish an Umbrella Mitigation Banking Instrument (UMBI) for future umbrella mitigation bank sites and Department of the Army permits. According to a mitigation needs assessment that DelDOT has completed for New Castle County, out of 54 projects proposed from 2020 to 2024, 42 are anticipated to have wetland impacts. As a result, DelDOT anticipates a significant future need for compensatory mitigation. The proposed UMBI would create a framework for restoring, enhancing, establishing and/or preserving tidal and non-tidal wetlands, riparian systems, streams and contiguous buffer corridors, as well as uplands and/or other aquatic resources, and their functions and values to compensate for unavoidable and permitted wetland and stream impacts. The purpose of this notice is to solicit comments and recommendations from the public concerning the Prospectus. More details are available in the “Public Notice” and “UMBI Prospectus” documents. Public comments are due by December 30, 2021.
