Wetland and Stream Mitigation

 Wetlands and streams provide vital ecological functions, such as filtering and storing water, and providing habitat for wildlife and plants. If development affecting a wetland or stream is inevitable, laws usually require that the loss be mitigated by creating and protecting wetland and stream either on the property or elsewhere in the watershed before any development is allowed. To speed up this process, wetlands are created ahead of time, and credits are sold through a wetland mitigation banking program. OES plans mitigation of the impacted wetland or stream, assesses wetland or stream quality, and delineates wetlands. OES buys and sells wetland mitigation credits through the wetland mitigation banking program. For more information on regulatory compliance services, see the "Permitting" section under "Plan."
