Valley County Commissioners unanimously approved a massive reduction Thursday to the area of impact around the city of McCall. Impact areas are not part of a city, but are subject to the city zoning code. Valley County’s decision for McCall is its most drastic; Donnelly’s area of impact was recently reduced by about 20%. Impact area residents don’t pay city taxes or vote for the city council, even though its zoning code decisions can impact your property. “Any land use decision is appealable to the county commissioners if it's within the impact area,” she said.
