Stormwater Comprehensive Plan
The Stormwater Comprehensive Plan is the City's long-range Stormwater and Natural Resources planning document. The Plan provides goals and guidance for managing all aspects of stormwater management and basin planning within Redmond.
Major elements of the Stormwater Comprehensive Plan include:
- Discussion about the Stormwater Utility
- Stormwater Technical Notebook
- Stormwater and Natural Resources Capital Improvement Program
- Regional Stormwater Facilities Plan
- Regional Stormwater Facilities Map
- WA State Department of Ecology's Letter of Support
- NPDES Phase II Permit
Stormwater capital improvement projects (CIP) are necessary to alleviate problems caused by existing development, as well as to prevent future problems that could result from planned development. In the Public Works Department's Environmental and Utilities division, typical capital improvements are aimed at constructing natural (streams and wetlands) or built (pipes and pond) elements to convey, detain, and treat stormwater runoff from developed properties without causing erosion of streams or degradation of water quality that would be harmful to fish and wildlife.
This program develops a "master list" of needed projects including both funded and unfunded projects. The costs, staff time and other resource needs associated with identified projects far exceed the amount of funding and resources available. Only projects that provide a public benefit or are a public responsibility are included.
Stormwater Capital Improvement Projects are divided into four categories, each with their own objectives and rating criteria:
- Habitat projects address the needs of the natural systems within the City. Project types include stream stabilization and enhancement, habitat rehabilitation, fish passage improvement, and buffer enhancement.
- Stormwater projects address the man-made elements including conveyance, flooding, stormwater quality treatment, and stormwater flow control. Stormwater quality treatment is aimed at protecting surface water (streams, the river and the lake) and groundwater (the City's drinking water resource).
- Neighborhood projects are small localized projects that impact residential customers, cost is less than $40,000, and are the result of inadequate stormwater collection or conveyance systems.
- Regional Facility projects address water quality treatment and detention facilities, and large conveyance systems, strategically located within the watershed to accommodate public and private developments upstream in a comprehensive and coordinated approach. These projects are substantially funded by new development through the City's Regional Facilities Program.
The overall CIP document is updated periodically in preparation for the next budget cycle. During each biennial budget cycle Council selects projects which should be included in the next two-year budget and which projects should be included on the six-year CIP list. The CIP is a planning tool that is subject to revision as new projects are identified or existing problems change in severity or extent.
