PAST WORKSHOPS

Descriptions and PowerPoint presentations from past workshops are available below.

STORMWATER SITE PLAN TRAINING WORKSHOPS – May and June 2005 (Completed)

Ecology hired TetraTech/KCM to conduct three free training workshops on preparing stormwater site plans.  The purpose of the training was to help design professionals and project reviewers begin to address the specific requirements of the Stormwater Management Manual for Eastern Washington when designing new development and redevelopment projects. During the workshop, participants applied the manual to a set of actual commercial, residential subdivision, and road project sites.  Changes in the design approach to accommodate new stormwater requirements were highlighted for each project.

INTRODUCTORY WORKSHOPS – Fall 2004 and Winter 2005 (Completed)

Ecology hosted eight free introductory workshops on the manual at locations throughout eastern Washington; the dates and locations are listed below. These workshops introduced the Manual to people unfamiliar with its purpose and contents and provided them with a brief overview and basic understanding of the “Core Elements” of stormwater management.  At the workshops, participants were asked to identify specific types of trainings that would be of interest and use to various user groups in the future. 

Here are the topics that were covered:

·        Eastern Washington Stormwater Project background information

·        Purpose of the manual and its application to development projects

·        Organization and contents of the manual

·        "Core Elements" of stormwater management

·        Next steps
