MCAS Beaufort Mitigation Bank
Beaufort, South Carolina
Marine Corps Air Station (MCAS) Beaufort contracted Tidewater to develop a wetland mitigation bank so that appropriate mitigation is available for unavoidable wetland impacts within the Installation’s properties. A 155-acre parcel owned by MCAS Beaufort was identified as a suitable mitigation bank due to the potential to restore extensive hydrologic and vegetative alterations that occurred over 100 years of agricultural land use. To date, the MBI has been accepted by the IRT and the USACE Section 404 permit application is pending review. Site preparation activities, including invasive species management, have commenced in upland and prior converted areas.
