What is wetland mitigation banking?

The concept of wetland mitigation banking has been around since the ’70’s. Basically, a wetland mitigation bank (bank) is a site where wetlands are restored, created, enhanced, or in exceptional circumstances, preserved, expressly for the purpose of providing compensatory mitigation in advance of unavoidable impacts to wetlands or other aquatic resources. Banking also creates an economic incentive for restoring, creating, enhancing and/or preserving wetlands.

Banks typically involve the consolidation of many small wetland mitigation projects into a larger, potentially more ecologically valuable site. Such consolidation encourages greater diversity of habitat and wetland functions. It also helps create more sustainable systems. Banks provide a greater likelihood of success over permittee-responsible mitigation projects, since the banks are up and running before unavoidable damage occurs to a wetland(s) at another site. With proper implementation, banking has the potential to increase ecological benefits, save money for project applicants, and improve efficiencies in application and permitting processes.

The wetland mitigation bank rule (WAC 173-700) identifies the criteria necessary for implementing and operating an environmentally sound banking system in Washington State.
