Staff reports SURPAC submission and developer interest in unmapped Ryan Road area (Winkelman Farms)

Staff informed the committee that the city has submitted a plan overview to SewerPAC (SURPAC) to map the remaining unmapped areas of Pewaukee required for DNR approvals. The submission begins a process of survey, review and consultation with adjacent communities.

Staff said the unmapped area includes the Ryan Road/Ryan Park area and noted a preliminary developer interest in a project referred to as Winkelman Farms. That project could require upsizing sewer mains and new connections; the original plan would have routed service through the Kotmeyer lift station, but city staff and the village of Pewaukee are exploring an alternative connection route to reduce the need for multiple lift‑station upgrades.

The staff member said SURPAC declined to process piecemeal plan amendments and that a full plan overview was therefore necessary. Staff also said the developer has so far been unwilling to fund the detailed studies needed to determine precise infrastructure changes and costs.

Staff confirmed required notifications were sent to neighboring jurisdictions during SURPAC’s outreach and said there were no requests to amend the plan in the earlier round of notices. The city will wait for SURPAC’s review, which staff said is expected to take at least about a year before approvals would be in place.

Next steps: SURPAC will review the overview, consult adjacent communities and environmental resources, and staff will return with any findings or project-specific study results when developers provide funding for the necessary analysis.
