Twin Falls County, ID Tree Protection: Parkway Planting (2026)

Title 2, Chapter 3 splits planting responsibility between county property and public road easements. Section 2-3-6, 'County Parks and County Property,' requires county parks and all other county property with growing trees to be kept to the same minimum tree-care standards, the International Society of Arboriculture ANSI A300 standards referenced in § 2-3-7, and directs the County Commissioners to promote certified-arborist training to implement that program. ' Because Twin Falls County contains several independent highway districts rather than a single county road department, the code deliberately defers the actual parkway-planting distance and species list to whichever highway district maintains the right of way, and to Idaho Power's own literature where an overhead line is involved.

The county tree board's role under § 2-3-4 is coordination, education and building the community forest master plan, not issuing a permit for a street tree or fixing how far back from the pavement it must sit. A resident planting a tree along a county or highway-district road therefore checks with that district rather than the county planning office for the governing distance.
