Full Breakdown
Under Nampa City Code § 7-1-1, property owners must keep vegetation, fences, and obstructions clear of the public right-of-way and vision-clearance areas so they don't create a traffic hazard or block sightlines. Trees in these areas must be trimmed to at least 9 feet above the curb or sidewalk and at least 14 feet above the street. Shrubs, fences, or walls that obscure sightlines can't exceed 30 inches above the curb line. Trees within the public right-of-way itself must be pruned by a city-licensed tree contractor at the abutting owner's expense under § 5-2-10.
Violations & Fines
Untrimmed trees or obstructions in a vision-clearance area can be declared a nuisance and abated under Nampa City Code § 3-4-2, with costs assessed to the property owner.
