Environmental Mitigation


Streamlined Permits, Rich Ecologies, Predictable Costs

Our Wetland & Stream Mitigation Solutions enable a clear path to project permits by delivering credits at any required scale and of such high quality that we back them with a guarantee.


RES effectively absorbs 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.

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).

RES guarantees the performance of our projects and can offer the security of surety bonding even for the largest, landscape-scale projects.
