Grantsville Council directs staff to refine sewer-rate options amid bond-financing constraints

Grantsville City Council on March 4 heard detailed analysis from municipal finance and engineering consultants on options for funding the city’s planned sewer improvements and directed staff to return with refined rate models.

City Manager Michael Resare introduced Alex Buxton of Zions Public Finance and Robert Rousselle of Ensign Engineering, who said the project currently has roughly $16 million identified from the State Water Quality Board plus some City funds but will likely require bonding to cover remaining costs. Buxton said the bond package must meet a minimum debt-service-coverage ratio of 1.25, which will require sufficient ongoing sewer revenue to support repayment.

Buxton and Rousselle presented a rate framework that combines a base fee with a usage-based component calculated from winter water-use averages. According to staff, the hybrid model would distribute costs more equitably across households—so that low-use residences would pay less than larger water users—while preserving revenue stability needed for bond covenants. Staff cautioned, however, that implementing usage billing will require system upgrades, additional data collection and administrative work.

Multiple council members raised equity concerns. Councilmember Butler said the city must balance affordability for residents on fixed incomes with the need to meet financing covenants and long-term maintenance costs. Councilmember Thomas asked about data and meter limitations; staff confirmed additional administrative changes would be necessary to support usage-based billing.

Public commenters who spoke earlier in the meeting had urged fairness in rate design. Leisa Lingwall questioned why prior developer impact-fee adjustments and proceeds from a prior water sale were not being directed toward sewer infrastructure, and Jeff Downward urged a usage-based sewer rate tied to water consumption rather than a flat charge.

City staff said some funding—approximately $16 million from the State Water Quality Board—was already identified, that other City funds had been applied, and that lower-interest or additional state funding could reduce long-term costs if secured. Resare and consultants emphasized timing considerations: pursuing certain funding sources or changing the rate structure at particular stages could trigger different regulatory or program requirements.

The Council generally supported exploring a usage-based option and directed staff to refine the model and provide multiple scenarios, including variations in base and usage fees and an analysis of implementation costs, equity impacts, and timing constraints. Staff were asked to return with options at a future meeting for further policy direction.

The discussion concluded with no formal rate adoption; Council action on rates will follow after staff returns with the refined proposals and supporting analyses.
