Grantsville staff and consultants propose annual capital‑plan and impact‑fee updates; changes reflect growth assumptions and project timing

Robert Russo of Ensign Engineering presented proposed annual amendments to Grantsville’s capital facilities plans and impact‑fee analyses at the combined Council and Planning Commission meeting on April 14. Russo said the transportation impact‑fee update will follow adoption of the transportation master plan; tonight’s packet addresses parks, water, wastewater, storm drainage and public safety.

Why it matters: The amendments update growth and demand assumptions used to size capital projects and calculate impact fees charged to new development. Changes affect the queue of public projects, the list of fee‑eligible costs and per‑unit fees that developers and future homeowners would pay if adopted.

Key takeaways: Russo said the consultant team updated demographics and used a ten‑year planning horizon with residential growth projections starting at about 3.5% and leveling to 4% in later years. He described changes to impact‑fee eligibility and per‑unit calculations: for example, the Northstar tank was removed from fee‑eligible costs until the connecting water line is available; the Bates Well is under construction; the satellite fire station remains on the long‑range project list but not fee‑eligible now. Public safety fee calculations were revised using 2025 police call data to estimate calls per unit (single‑family ~0.575 calls/unit; multifamily and nonresidential show higher call rates), which changed fee allocations across land‑use types.

Projects and funding: Russo listed roughly 28 projects in the ten‑year window, including wastewater improvements (Westbank interceptor upsizing and treatment‑plant upgrades), water main replacements and collector lines. He said some storm‑drain projects to date have been developer‑constructed and therefore not currently fee‑eligible; if the city later undertakes regional drainage projects, those could be added. Russo cautioned the council that impact‑fee levels are legally constrained and locally competitive; setting fees too high risks developer pushback and potential legal challenges, but setting them too low leaves capital shortfalls.

Policy questions raised: Council and commission members asked whether the city should use a buffer to keep fees competitive with neighboring jurisdictions and whether the city will continue to grant fee waivers for economic development. Russo said impact‑fee decisions are a balance: cities try to stay competitive while covering necessary improvements, and fees are adjusted annually to reflect changing needs and capacity.

Next steps: The amendments are part of the annual update process; transportation figures will be revisited after the transportation master plan is finalized. The consultants will provide full reports and cost tables for staff review and future hearings.
