Pewaukee council directs staff to draft policy on capping water and sewer assessments, delays final cap decision

Pewaukee — The Common Council on Tuesday directed staff to draft a formal policy on capping special assessments for municipal water and sanitary sewer connections and to return with recommended cap amounts and supporting cost information, after more than two hours of discussion but no final vote on a cap.

Council members said the issue matters because construction prices and the cost to serve isolated parcels have risen sharply, producing assessments that some property owners have described as potentially life-changing.

City Engineer Maggie (last name not stated) told the council that "in the community, we have 998 parcels that have sewer available to them. 611 parcels are not connected, so that's about 9%" and that 1,623 parcels — about 23% — do not have municipal water available. She said the city’s connection requirements differ: a mandatory sewer hook-up for residential properties occurs within 15 years of availability while water has in the past been required only at time of sale.

Maggie presented analysis and several example calculations the staff used to evaluate the fiscal impact of different caps. Using broad assumptions, she said a scenario with a $50,000 total cap (split between water and sewer) would shift roughly $12.8 million from future property owners to the sewer utility and about $4.8 million to the water utility over the period in which properties are ultimately served. "I wanted to give you an idea of what kind of financial impact that could potentially be to the utilities," she told the council.

Council members expressed conflicting priorities in a lengthy debate. Some members, including those representing neighborhoods with private wells and septic systems, said forcing connections into areas where residents are satisfied with their private systems risks saddling longtime homeowners with heavy bills and shifting the difference onto current ratepayers. Others emphasized long-term public-health and environmental benefits of extending municipal services and said deferred private wells and failing septic systems threaten groundwater and can become more expensive over time.

Councilmembers asked for a policy that would ensure staff bring preliminary cost information earlier in project development — before the city spends significant engineering funds — so elected officials can decide whether to require service extensions when road projects or other triggers arise. The council also asked staff to collect comparative data from recent development projects and contractors on typical per-lot utility installation costs to help set a fair cap.

No formal cap was adopted at the meeting. Mayor (name not provided) summarized the outcome: staff will draft a written policy describing when the city will pursue municipal service extensions, what information must be presented to the council before costly engineering is authorized, and the mechanics for a prospective assessment cap. "I'm gonna do my best to put a policy together for you guys to consider," Maggie said. The council agreed to revisit the cap numbers and adopt specific amounts in a future meeting.

Next steps: staff will prepare a draft ordinance/policy for council consideration that (1) defines the decision point in the road/project schedule when council direction is required; (2) proposes specific cap amounts (and the methodology used to compute them); and (3) compiles contractor/developer cost information to justify the proposed cap. Public hearings on individual projects will still be required under state and local law.

The discussion will shape several projects already on the near-term calendar, including a public hearing that followed later in the same meeting on a Blue Mound Road water and sewer extension.
