Study recommends Ivins set aside 0.826% of sewer replacement value (about $834,000/year) to fund repairs

A lifecycle analysis presented at the Ivins City Council work meeting on June 19 recommends the city begin setting aside roughly 0.826% of its sewer system replacement value each year to build a repair-and-replacement (R&R) fund.

Chuck, the presenter, said the recommendation comes from an intern-driven GIS inventory and a decade-by-decade financial model that uses conservative assumptions: 2.5% annual inflation, a 5% nominal investment return (about 2.5% real), a 50/50 split between rehabilitation and full replacement, and an assumed service life of about 75 years for many components. "If we save this point 826%, right now that's $834,000 per year," Chuck said.

The presentation traced how the model assigns ages to every pipe and then projects repair and replacement needs as the system grows. Chuck said the model was run out 200 years to test stability and to see whether repair and replacement costs would stabilize or escalate under the assumptions. He stressed the model is conceptual and omits bonding assumptions: "It's not a real projection of what's actually going to happen," he said, "it's a conceptual idea of how the system behaves under these assumptions."

Why it matters: Council members framed the recommendation as a way to avoid large future bond debt and to smooth costs across generations of residents. The mayor said the state may eventually require a similar approach for cities, noting that legislatures have already required some HOA reserve studies; council members agreed that a long-term fund reduces the chance of imposing large bond burdens on future residents.

Legal and governance issues: Several council members and staff raised questions about how to protect a built-up fund from future political decisions. Dale, identified in the transcript as city attorney and city manager, explained the legal distinction: "There's a difference between a dedicated account and a restricted account," he said, and advised the council that whether funds can be restricted by law depends on state code and will require follow-up.

Documentation and next steps: Chuck offered to document the R&R-philosophy in a memorandum and include it as an appendix to the master plan. Staff suggested the council could also note the approach in the rate study and the annual financial report to make the intent explicit to future councils. Staff and Chuck said they will provide the model and supporting spreadsheets to the council; Kate (staff) agreed to research any statutory limits on restricted accounts.

Interjurisdictional coordination and public hearing timing: Staff noted Santa Clara had submitted a memo asking for adjustments to assumptions on projects shared between the cities. Because some projects are shared, staff said they would review Santa Clara's memo before finalizing a public hearing originally targeted for July; if changes are minor the July hearing can proceed, but significant changes could require postponing the hearing.

What the council agreed to do: The council did not adopt a formal ordinance at the meeting but directed staff to provide the model and documentation, research statutory options for restricting or dedicating funds, and to proceed toward a public hearing (timing contingent on the Santa Clara memo review). The presentation also included an offer to provide the full spreadsheet to council members after the meeting.

Ending: The council continued the master-plan conversation with several follow-up assignments to staff and asked staff to return with final materials for public review and the scheduled hearing window.
