This two-day class will provide wetland regulators and consultants with a practical tool for calculating if mitigation projects will adequately replace the functions and values lost to altered wetlands. The class is based on a new method developed by the Department of Ecology called ""Calculating Credits and Debits for Compensatory Mitigation in Wetlands of Western Washington"" (Ecology Publication #10-06-11). This method is designed to provide guidance for both regulators and applicants during two stages of the mitigation process: 1) estimating the functions and values lost when a wetland is altered, and 2) estimating the gain in functions and values that result from the mitigation.

The Credit Debit Method is based on the Washington State Wetland Rating System for Western Washington (Ecology publication #04-06-025). This workshop however does not provide training in the wetland rating system. Training in the wetland rating system is strongly suggested as a PRE-REQUISITE for this workshop.

This training will take place at the Lacey Community Center and include instruction  wetlands in near the training site, so dress appropriately. (6 CM AICP Credits/CEP Points).

You will receive a copy of the “Credit-Debit” manual. Note:  This class will qualify you to use the 2014 Wetland Rating System if you have already taken the 2-day training in the older rating system in Western WA.

Please reach out to Sara Brostrom (bros461@ecy.wa.gov) if you require an accommodation for this training (audio, visual, mobility, or other). 

Washington State Department of Ecology staff, if you need a reasonable accommodation to successfully attend this training, please contact the Core Training Team.

Additionally, we can offer scholarships to cover the registration fees with each training. Please reach out if you need a scholarship in order to participate in the training.
