Civil Engineering in Parma, Idaho.
Canyon County's westernmost incorporated city — agricultural, stable-population, historically low-development-activity. Parma shares area of impact administration with Canyon County under a joint exercise of power agreement.
Agricultural character with joint Canyon County administration.
For parcels in the impact area but outside city limits, both Canyon County's zoning code AND the City of Parma's Subdivision Ordinance apply — with the subdivision ordinance controlling in cases of conflict, except for flood hazard and addressing matters.
Notus/Parma Highway District 2 (separate from ACHD) — coordinate directly on any access or improvements.
Applications converting agricultural land face the strongest public scrutiny. Parma was not seeking AOI expansion in the 2025 Canyon County review.
