Summit County districting commission reviews legal limits, scheduling and first draft precinct groupings

The Summit County Districting Commission met in person for its inaugural session to begin drawing five council districts required by the Utah Legislature and to set a short timeline for map development and review.

The commission was told the state law requires districts to be based on total population from the most recent decennial census, to be contiguous and reasonably compact, and to keep existing voter precincts intact. “The county districting commission shall divide the county into districts by, a, relying on the total population enumeration of the most recent decennial census, b, ensuring that between districts, there is less than 10% total population deviation, c, ensuring that each district is contiguous and reasonably compact, b, ensuring that district boundaries do not divide existing voter precincts, and, e, complying with the United States Constitution,” said Eve, Summit County clerk, while reading the statute aloud.

Why it matters: House Bill 356 (2025) requires Summit County to move from at-large council elections to five geographic districts. The commission must produce a map that the county council can hold a public hearing on and approve; the commission was told a completed map is needed by Oct. 1 so the council can meet the bill’s subsequent 30-day hearing/approval window.

Key legal and procedural constraints discussed included: the use of total population (not registered voters) from the 2020 census, a maximum total population deviation between the largest and smallest districts of less than 10% (the commission cited U.S. Supreme Court guidance for the 10% rule), contiguity and reasonable compactness, and the prohibition on splitting existing voter precincts. Commission members also discussed the statutory process for assigning council members to districts after maps are adopted: the council will draw lots (after the council approves a map), the clerk’s office confirmed.

The commission also agreed to a practical schedule for its own work. The chair said two upcoming meetings — June 30 and July 7 — would be removed from the calendar to reduce scheduling conflicts; members tentatively agreed to reconvene on July 17 and to keep later dates available if necessary. The clerk’s office will circulate a revised schedule to members.

Staff assignments and next steps: the Summit County clerk’s office will produce three items for the commission before the next meeting: (1) a PDF map showing the precinct groupings discussed at the meeting, (2) a spreadsheet listing each precinct name with its 2020 census population, and (3) a printable PDF of the interactive voter-precinct map for reference. The clerk said she would confirm that the population numbers staff are providing are the official 2020 census figures and aimed to deliver materials at least one to two weeks before the July meeting so commissioners have time to review them.

Population targets and first grouping work: staff described rough population targets and initial precinct groupings. Using 2020 census totals, staff said the rough target per district is roughly 8,000–9,000 residents (county population divided by five). Staff gave school-district-level totals as context: Park City School District ~27,665; North Summit ~6,063; South Summit ~8,981. Eve and staff showed how several small adjacent precincts could be added to North Summit to reach a working district total of about 8,520 (examples cited in discussion: Silver Creek Upper 50 — 9 people, Wanship West 8B — 3 people, SCRU 5 — 531, Kimball Canyon 5 — 239, Silver Creek Lower 5 — 841, Bittner North 15 — 826). Staff also reported a Park City municipal total of about 8,365 (precinct aggregation) and suggested keeping municipal boundaries intact where feasible as a community-of-interest.

Commissioners discussed a straightforward approach proposed by Mayor Wilson Hume — start at the county edges and work toward the center (leave South Summit alone initially, add adjacent precincts to North Summit until population targets are met, then reconcile the Snyderville Basin/Park City area). “I don't know as we need to over complicate it… my thinking is… leave [South Summit] alone and then go to North Summit and go west until they've got their number,” Mayor Wilson Hume said.

The clerk’s interactive precinct map (publicly available via the clerk’s elections page) was used in real time to show precinct names and point out small unpopulated or very-low-population precincts that will need to be assigned for contiguity even though they add little population. Commissioners asked staff to provide clearer, printable PDFs with visible cross-hatching and a numbered list of included precincts and populations to make it easier to compare options.

Decisions and directions (non-vote): the commission chair instructed staff to remove two planned meeting dates (June 30 and July 7) and to circulate a revised schedule; staff agreed to provide the maps and spreadsheets before the next meeting. Commissioners agreed to notice subsequent meetings as “discussion and possible decision” so members and the public know a formal vote could occur.

Formal action: the meeting ended with a motion to adjourn moved by Mayor Worrall and seconded by Mayor McCormick; the chair called the voice vote and the motion carried.

What’s next: Staff will return with precinct-level maps and a population spreadsheet based on 2020 census counts for commissioners to review in advance of the July meeting; commissioners said they expect to review multiple map options, refine precinct groupings, and — with adequate notice — could make a final vote at a later meeting once all members have had time to review proposed maps.
