The City is embarking on a comprehensive Stormwater Planning effort to meet Council priorities for an Island-wide Stormwater System Plan and also to meet Stormwater Planning requirements included in the 2019-2024 Western Washington Phase II Municipal Stormwater National Pollutant Discharge Elimination System (NPDES) Permit.
Stormwater System Plan (SWSP) Primary Objectives:
- Offer a single comprehensive resource guide for stakeholders, staff, and decision makers for sustainable and adaptive stormwater and surface water management on Bainbridge Island.
- Support full compliance of the Western Washington Phase II Municipal Stormwater NPDES permit and Industrial Stormwater General Permit; and provide a Stormwater Management Action Plan to follow.
- Inform strategy and transparency with identifying and prioritizing stormwater infrastructure asset improvement projects. Including enhancements to address deficiencies in asset inventory data, tracking, and reporting.
- Appraisal of current and needed relevant City programs, projects, and staff levels to meet present and future service demands and regulatory requirements for surface water and stormwater management, operations and maintenance, planning, development, and re-development.
- Evaluation of funding sources and fund utilization for surface water and stormwater management, including but not limited to grants and Storm and Surface Water Utility (SSWM) fee rates and revenue.
- Assess real and potential impacts of climate change on surface water and stormwater on Bainbridge Island and measures and activities to apply to minimize impacts.
- Propose improvements to internal and external enforcement mechanisms and procedures to implement to successfully achieve the objectives therein.
The NPDES requirements achieved by this effort briefly entail the following:
