Canyon County roads are split among 4 highway districts, while Nampa and Caldwell run their own city streets. A porta potty on a public road or shoulder needs an OK from whichever agency owns that road. A unit on private farm ground or a driveway needs no road permit.
The county keeps a list of Canyon County highway districts with each website. Land use outside city limits goes through Canyon County Planning and Zoning.
State highways like US-95 and ID-55 belong to the Idaho Transportation Department. Keep units well off those shoulders.

Canyon County farm ground turns soft after irrigation and spring rain. The delivery truck needs firm ground within about 30 feet of the drop spot. Open fields catch strong wind. A lone 165-pound unit does best beside a building, fence or parked trailer.
Gravel farm lanes work fine in dry weather. Tell us about canal crossings, low bridges or narrow gates before the drop.
From November through March, every tank gets antifreeze at no charge. Hand-wash stations can freeze, so winter crews often switch to sanitizer.
