Caldwell Asphalt Paving Guide: Costs, Permits, and Timing

Caldwell has warm summers, cold winters with frequent freezes, and a dry climate, and work in the City right-of-way needs an approved right-of-way permit and a Public Works License. This guide covers Caldwell's right-of-way permit rules and how to time paving around the local weather. We did not find a published Caldwell cost guide, so we do not list local prices; get written quotes from more than one contractor. The contractor list above shows paving pros who serve Caldwell on Main Street.

City permits and the public right-of-way

Paving that stays entirely on your own lot does not touch the public right-of-way, but driveway, sidewalk, and curb work at the street does.

Right-of-way permit. Caldwell's Right-of-Way Permits page says to allow at least 2 business days for processing and not to start work until the permit is approved. A traffic control plan must accompany the application, along with proof of at least $1,000,000 in insurance naming the City, and payment.

License and penalties. A valid Public Works License from the State of Idaho is required to work in the right-of-way. The City lists a penalty of $1,270.21 per day for work without an approved permit, rising for repeat violations. Questions go to Engineering at (208) 455-4639.

Caldwell weather and the best time to pave

Caldwell does not have its own NOAA normals station, so we use nearby Deer Flat Dam. Its 1991 to 2020 normals show about 10.0 inches of rain a year. January is the wettest month at about 1.22 inches, and August is the driest at about 0.19 inches.

July highs average about 90 degrees, and the station averages about 41 days a year at 90 degrees or hotter. Winters bring about 106 nights a year at freezing or colder, and January highs average about 40 degrees.

Our tip for Caldwell homeowners: late spring through early fall is the best window for paving and sealcoating. Fresh asphalt and sealcoat need warm, dry days, so plan around the long freeze season.
