Valley County commissioners table decisions on Cascade, Donnelly impact-area maps until next week

Valley County commissioners on April 28 opened a combined public hearing on draft ordinances and a resolution to adopt updated areas of city impact for the City of Cascade and the City of Donnelly, then delayed final votes until a follow-up meeting next week.

County planning staff told the board the 2024 change to Idaho Code 67-6526 requires counties and cities to update impact-area boundaries for adjacent municipalities and meet statutory criteria by Dec. 31, 2025. “The deadline for compliance with the state statute is Dec. 31, 2025,” planning staff member Cinda said during the staff presentation.

Staff presented two different ordinance drafts for Cascade — one that would reestablish a greatly reduced Cascade impact area matching the city limits and a second draft that would include two parcels requested by property owners identified in correspondence from Little Enterprises LLP. For Donnelly staff presented an agreed-upon map that reduces the Donnelly impact area from the previous boundary and a related Valley County resolution (Resolution 2025-10) to adopt the county comprehensive-plan provisions applicable to Donnelly’s impact area.

Why it matters: impact-area boundaries determine where cities may later annex property under Idaho law and which local land-use regulations apply in the interim. County staff also emphasized the statute’s five-year standard describing lands “very likely” to be annexed in the near future; commissioners repeatedly referred to that five-year annexation horizon during deliberations.

What speakers said and asked - Mark Butler, appearing as a representative for the City of Donnelly, praised the approach that makes the Valley County comprehensive plan the controlling policy within Donnelly’s impact area. “I really like that language,” Butler said, urging that the county apply its 2023 comprehensive-plan language rather than relying on Donnelly’s older 2002 plan. Butler also flagged typographical references in the draft Donnelly ordinance that incorrectly name “Cascade” and asked staff to correct them before adoption. - Planning staff described the technical criteria the board must weigh: anticipated commercial and residential growth, geographic features, transportation connectivity, areas where municipal sewer and water are expected within five years, and limits on impact areas (typically not more than two miles from city limits unless large parcels make that impractical). - City of Cascade had previously signaled it did not want to establish a broad area of city impact, but staff said the county received a request from adjacent property owners (the Littles) asking that two parcels be left in the Cascade impact area. Staff noted Cascade officials say they prefer infill development within current city limits and lack capacity to pursue aggressive annexation at this time.

Formal actions and next steps - No ordinances or resolutions were adopted. Commissioners voted to table the public hearing and associated ordinances/resolution so staff can prepare written findings of fact and conclusions of law for the board to review. The board scheduled a continuation for next week — a 30-minute session at 10:30 a.m. — to finish deliberations and consider final action.

Staff told the board the ordinances would not be recorded until the written findings and conclusions are approved; staff recommended the board choose between the two Cascade ordinance drafts (with or without the Little parcels) and adopt the Donnelly ordinance and the matching comprehensive-plan resolution once the findings are prepared.

Background and context Idaho Code 67-6526 sets standards for areas of city impact and states a county makes the final determination on impact-area boundaries. Idaho Code 50-2-222 governs annexation and generally requires annexations to occur inside established impact areas or follow the statutory annexation process. The county emphasized the statutory Dec. 31, 2025, compliance date during the hearing.

What remains unresolved Commissioners asked for more detail on infrastructure capacity (notably where sewer and water service is likely to be provided within five years) and requested staff complete the worksheet and prepare findings that document the board’s factual and legal rationale. The Little parcels’ inclusion in Cascade’s impact boundary and the exact text of Donnelly’s comprehensive-plan adoption language (and the typos Butler noted) must be finalized before the board can adopt the ordinances and resolution.

The board will reconvene next week for the continued hearing and possible final action.
