Wetland & Stream Mitigation

Streamlined Permits, Rich Ecologies, Predictable Costs.

RES Wetland and Stream Mitigation Solutions enable a clear path to project permits. We deliver credits at any required scale and of such high quality that we back them with a guarantee, allowing us to effectively absorb the regulatory risk for our clients.

RES is uniquely structured to deliver timely mitigation credits that also endure the test of time, all under fixed-price contracts. We offer end-to-end turnkey solutions and have assembled in-house all the interrelated capabilities needed to move quickly, build high-performing sites, and control costs. We implement projects at every scale, including large areas of impact that may require both wetland and stream mitigation. RES guarantees the performance of our projects, and can offer the security of surety bonding even for the largest, landscape-scale projects.

Our teams have deep knowledge, across wide geographies, of nuances in Section 404 permitting of the Clean Water Act, as well as specific understandings of state-level factors in watersheds across regulated districts. Among regulators, RES has a reputation for high-quality mitigation solutions, whether in the form of bank credits or permittee-responsible mitigations (PRMs). We have the industry’s largest portfolio of successful wetlands and stream mitigation assets, along with over $500 million in surety bonding capacity from A-rated or higher institutions, including Zurich, to cover the entire lifecycle of any project.
