Selecting Wetland Mitigation Sites Using a Watershed Approach

This class will teach you how to apply a "watershed approach" when selecting sites for compensatory wetland mitigation in western Washington. Such an approach is now required by recently adopted federal rules. The training is based on the guide for "Selecting Wetland Mitigation Sites Using a Watershed Approach (Western Washington)" that was jointly written by the Department of Ecology, the U.S. EPA, and the U.S. Army Corps of Engineers to meet this need. A watershed approach means that a site is selected based on the environmental conditions of the surrounding watershed as well as at the site itself. The training will include several exercises that apply the method to real sites. You will also receive a copy of the manual.

Lunch is provided.

Note:  This is an excellent class to take before attending the “Using the Credit-Debit Method for Estimating Needs in Compensatory Wetland Mitigation” class.
