A wetland bank can be a successful and accepted way to mitigate for the loss of wetland habitat areas due to transportation projects.
The EPA s defines a wetland mitigation bank as a “a wetland, stream, or other aquatic resource area that has been restored, established, enhanced, or (in certain circumstances) preserved for the purpose of providing compensation for unavoidable impacts to aquatic resources…” The Water Resources Development Act of 2007 calls mitigation banking “the preferred mechanism for offsetting unavoidable wetland impacts associated with Corps Civil Works projects.” Wetland banks are regulated by the The U.S. Army Corps of Engineers and the U.S. Fish and Wildlife Service with guidance from the Environmental Protection Agency.
EPA rules call for a “no net loss” policy in compensating for wetlands that are impacted by transportation or other projects. An ecological assessment assures that the bank area is functioning as intended. A credit system, representing the value of the compensation, assures that lost wetlands are adequately compensated for. Banks must be monitored and managed on an ongoing basis to make sure performance standards are met.
UDOT has established a wetland a mitigation area, called the Northern Utah County Mitigation Bank, which compensates for of transportation project impacts in Utah County, including I-15 CORE and Pioneer Crossing. The NUCMB totals 120 acres and is located in Lindon, Utah. This wetland bank will eventually provide 76 mitigation credits — enough capacity to provide mitigation for any UDOT FHWA transportation project throughout the majority of Utah County .
Advantages of UDOT’s mitigation bank
The NUCMB provided a cost-effective way to mitigate wetland impacts in northern Utah County. Having a mitigation bank also accelerated the permitting process, saving taxpayers millions of dollars and years of time. UDOT, along with private sector partners, worked together throughout the process to design, permit and monitor the NUCMB.
