City of McCall presents data-driven area-of-impact map; commissioners question sewer capacity, public-land inclusions

City of McCall staff and outside consultants presented a data-driven proposal to redraw the city's Area of City Impact (AOI) boundary at a joint meeting with the Valley County Board of Commissioners, citing Idaho Code criteria and a 2-mile statutory planning buffer. The presentation used 24 mapped criteria organized under five categories drawn from Idaho law (anticipated growth, geographic factors, transportation, water/sewer service horizons, and other public-service districts) to score parcels and produce a modified AOI boundary for county consideration.

The proposal was described to commissioners and the public as a starting point for negotiation rather than a final decision. Diane Kushline, principal consultant with Kushlin Associates, said the project's goals included statutory compliance and better intergovernmental coordination: "the overarching goal is for us to work together to meet the requirements, on the goals and policies," she said. Megan Moore, senior associate planner with Logan Simpson, and Ben Esterling, GIS analyst with Logan Simpson, explained the methodology: they assembled 24 spatial layers, weighted them into the five statute-based categories, and aggregated those into an overall suitability map that produced specific expansions and exclusions compared with the current AOI.

Why it matters: the AOI defines the transitional planning area between the City of McCall and unincorporated Valley County and informs annexation planning, service provision and zoning relationships. Bill Punkenny, city attorney, reviewed relevant state law and emphasized criteria the county and city must "consider" under Idaho Code 67-65-26, including anticipated growth, geographic factors, transportation connectivity, areas where municipal water and sewer are expected within five years, and public-service district boundaries. He added the statute also directs that an area of impact generally should not exceed lands "very likely to be annexed" within five…
