Location
This filing changes the city's rules rather than a specific site, so there's nothing to map.
From the filing
The application's description as it appears in Canyon County's record. See the official record
Canyon County commissioners adopted an ordinance that confirms and modifies the area of impact boundary for the City of Greenleaf, which sets the unincorporated land where the city has a say in planning. The boundary is shown on a map dated October 30, 2025, and the ordinance says the boundary may be reevaluated later by the city and county.
The applicant, City of Notus, represented by Mayor David Porterfield, requests an ordinance update to comply with State Law 67-6526, by reducing the Area of Impact on all. The original request supplied by the applicant asked for a reduced area of impact with two potential map options. Map #1 (Exhibit A2) showed a reduction that was approved by the Notus City Council. Map #2 (Exhibit A3) was created after more reflection on the State law and the five criteria.
