Wausau Completes Stormwater Utility Feasibility Study and Management Plan Update

In the heart of Wausau's city hall, a pivotal discussion unfolded as the Infrastructure & Facilities Committee convened to address the pressing issue of stormwater management. On August 14, 2025, city officials and engineers gathered to unveil the findings of a comprehensive stormwater quality management plan update and a feasibility study for a proposed stormwater utility, a project funded by a grant from the Department of Natural Resources.

Justin Getoski, a municipal engineer from Strand Associates, presented the findings, emphasizing the need for a stormwater utility to alleviate the financial burden on property taxpayers. The proposed utility would charge users based on the amount of stormwater runoff generated by impervious surfaces, such as rooftops and parking lots, rather than relying solely on property taxes. This approach aims to create a fairer system where those contributing more to runoff pay accordingly.

The feasibility study revealed that Wausau has approximately 30,419 equivalent runoff units (ERUs), with one ERU representing an average of 2,836 square feet of impervious area. The projected annual costs for single-family residential property owners would range from $64.51 to $170 over the next 30 years, depending on the stormwater budget needed to maintain and improve the city's stormwater infrastructure.

As the discussion progressed, committee members learned that the implementation of a stormwater utility could provide a stable revenue source for necessary projects, including compliance with state regulations and improvements to water quality in local rivers and lakes. The study highlighted the potential for a credit system, rewarding residents who take steps to reduce runoff, such as installing rain gardens or rain barrels.

The meeting concluded with a call to action for the city to consider the next steps in establishing the stormwater utility, including forming a task force to guide the implementation process and ensuring transparency with the community. As Wausau faces increasing challenges from climate change and urban development, the proposed stormwater utility represents a proactive measure to safeguard the city's infrastructure and enhance the quality of life for its residents.
