Chippewa Falls-Eau Claire Urban Sewer Service Area Plan Update
​
2024 Plan Update
The existing Sewer Service Area (SSA) Plan for the Chippewa Falls-Eau Claire urban area has not been fully updated since its adoption in 2007, and the urban area has changed significantly since that time. West Central Wisconsin Regional Planning Commission (WCWRPC) is working with the Metropolitan Planning Organization’s (MPO) Policy Council and Wisconsin Department of Natural Resources (WDNR) to update the SSA Plan. The plan update process commenced in May 2024 and a draft plan is expected to be completed in 9-15 months, then submitted to WDNR for approval.
This INFORMATIONAL SHEET provides an overview of the SSA Plan update purpose, scope, and approach.​​
​The MPO Policy Council has approved this Study Area map for the SSA Plan update. The Study Area is area for which data is being gathered during the planning process and has no regulatory significance. The Study Area is not the Sewer Service Area and there is no expectation that the entire Study Area will be developed or provided sanitary sewer within the next 20 years.

The sewer service area (SSA) delineates areas with a potential for sewered development by 2025, excluding ESAs. Inclusion of lands within the SSA boundary does NOT determine or guarantee that these lands will be developed, sewered, or annexed by 2025.

SSA & ESA Map
The Sewer Service Area & ESA webmap was developed using ESRI ArcGIS to allow users to quickly view layers developed for the 2018 policy update. This map contains all SSA & ESA layers described above using the most recent available data as of January 2018.
Click on the image below to access the webmap and once loaded, the map will only display the Sewer Service Area Boundary. As users zoom into the map, layers will become active, which helps improve the speed of the webmap layers loading in the viewer.
SSA Plan Conformance Tracking
Tracking of conformance with the Sewer Service Area Plan is required. In particular, a brief tracking form is completed for any Section 208 review, steep slope (20+%) or other ESA encroachment, or SSA Plan amendment. Direct access to this web-based form is limited to WCWRPC, county, or municipal staff responsible for reviewing or approving the related SSA planning actions, though the data entered into the form is available upon request as a public record.
