WES identified approximately 15 members of the development community (development engineers, planners, and others who utilize the rules and standards) to interview about sanitary and stormwater design standards. Information obtained during the interviews was compiled into a Stakeholder Interview Summary Memo.
WES convened a Task Force to review and come to consensus regarding policy issues and technical standards that will be addressed in the rules and standards update. Members of the Task Force included both developers and municipal agency partners. The Task Force workshops were intended to introduce and get feedback on proposed policy and technical decisions.
Task Force Workshops included the following topics:
| Workshop #1 Project Overview and Task Force Role | agenda | notes | presentation |
| Workshop #2 Stormwater Performance Standards (Site Planning, Water Quality and Flow Control) | agenda | notes | presentation |
| Workshop #3 Stormwater Minimum Requirements and Facility types (including green infrastructure and proprietary systems) | agenda | notes | presentation |
| Workshop #3A Flow Duration Matching Tools | agenda | presentation | |
| Workshop #4 Sanitary and stormwater fiscal policies | agenda | notes | presentation |
| Workshop #5 Proposed Policies | agenda | presentation |
WES has completed an extensive Stakeholder Outreach Process. Below are summary documents from the Stakeholder Outreach.
