Compensatory mitigation offers a viable way to protect the long-term health of the nation’s watersheds, and its success relies on a robust review and approval process that ensures that the protections in federal regulations are implemented in practice on the ground and that compensation projects effectively offset permitted impacts. However, the review and approval process can often be lengthy, sometimes greatly exceeding the regulatory timelines. In this episode, Rebecca Kihslinger, Director of ELI’s Wetlands Program, discusses a new ELI research report that aims to identify some of the main impediments to efficiency in compensatory mitigation project review, as well as best practices to improve the process and ensure timely, ecologically viable mitigation outcomes.
