Rio Vista committee recommends new sewer rates after debate over funding and timeline

The Rio Vista Municipal Rates & Utilities Committee voted 3–1 on July 25, 2024, to recommend proposed sewer-rate adjustments for the city’s Northwest and Beach wastewater plants to the full city council, following a multi‑hour presentation by consultants and a detailed exchange about financing, capital projects and outreach.

Consultant Margo from NBS summarized the study methodology and five‑year financial plan, saying the model separates operations and maintenance from capital reserves and assumes the two plants will be consolidated after the five‑year rate period. “So next slide 15 reflects that, is that 1st year adjustment is reduced to 60% rather than the 65 that was shown in the last presentation,” the consultant said, describing how the first‑year increase was adjusted in response to committee feedback.

Why it matters: the package is intended to fund immediate deferred maintenance at the Beach plant and interim improvements at the Northwest plant, while also establishing a rate path the city can show to potential Clean Water State Revolving Fund (SRF) lenders. Committee members pressed staff for clarity on which capital projects would be financed by SRF loans, grants, connection‑fee reserves and rate‑funded capital. The consultant said SRF funding was assumed at $11,360,000 overall and identified the wastewater consolidation project and a recycled‑water tank/pump/distribution project as major SRF candidates; staff said an anticipated $960,000 grant would assist the recycled‑water project.

Several members raised accounting questions and asked for clearer documentation. Finance staff (Jen Lee) explained a historical coding issue that moved some vendor payments between accounting lines. “The number in 2324 budget is the correct number,” she said, explaining that Veolia costs and other contractual services were recorded separately in different years and that the rate model contains a table showing the detailed breakdown; staff offered to provide supplemental tables and footnotes for transparency.

Committee members debated rate design and timing. One member criticized the draft as “front‑loaded,” citing an example the consultant had shown where the Northwest customer charge would rise roughly 60% in year one, 30% in year two and then smaller increases in following years; that member urged smoothing the increases to make them more palatable to the public. Other members pushed back, saying the city’s deferred maintenance and permit risks require aggressive near‑term funding. Staff emphasized that demonstrating the ability to repay SRF debt is essential to scoring well in the SRF application process and to keeping the consolidation schedule on track.

On the Beach plant specifically, staff and consultants described a list of near‑term upgrades—electrical work, blower modifications and diffuser upgrades—deemed necessary to keep the facility operating within permitted limits until consolidation. Committee members warned postponing those repairs could risk permit violations or emergency shutdowns.

Outcome and next steps: the committee voted to forward the proposed Northwest and Beach sewer rates to the city council with a recommendation (committee reported the vote as 3–1). Members requested that staff prepare supplemental financial tables showing the use of connection‑fee reserves, grants and rate funds; include revision dates on slide decks; and develop an expanded public‑outreach plan. Michelle (committee member) offered to draft an outreach schedule and convene a subcommittee to accelerate public engagement.

What comes next: staff will supply the supplemental tables and work with the committee on outreach materials before the council receives the recommendation; the SRF application process and the calendar for design and environmental review will continue to be coordinated with the goal of meeting the state funding cycle.
