Stream Compensatory Mitigation -- The Watershed Approach

December 14, 2018 1:00 pm — 2:30 pm

ELI is hosting a series of webinars on the policy, practice, and science of stream compensatory mitigation. Webinar topics are based on the findings and recommendations of the 2017 report Stream Mitigation: Science, Policy, and Practice and selected in coordination with an Advisory Committee of stream mitigation experts. The series will cover a range of issues from assessing stream functions and conditions to restoration approaches and long-term success of compensation projects. This ten-part series is funded by an EPA Wetland Program Development Grant.

Stream Compensatory Mitigation Webinar Series: The Watershed Approach

The 2008 Rule requires that the Corps “use a watershed approach to establish compensatory mitigation requirements in DA permits to the extent appropriate and practicable.” (33 C.F.R. § 332.3(c)(1)). Stream compensatory mitigation guidance documents generally do not address in detail what a watershed approach entails or provide specific instructions on how watershed concerns should influence site selection or mitigation design, especially when watershed plans are absent. This webinar will examine the watershed approach in practice. First, Nick Miller (Science Director, The Nature Conservancy in Wisconsin) provided an overview of a watershed approach framework and TNC's experience with the development of an online decision support tool for a watershed approach. Then, Tim Baumgartner (NC DMS) discussed watershed planning in North Carolina and how it is applied to ILF decision-making. Finally, Dana Hicks (Oregon Department of State Lands) focused on how Oregon has integrated the watershed approach into mitigation policy with a focus on the state’s stream assessment tool.
