Issaquah Asphalt Paving Guide: Costs, Permits, and Timing

Issaquah has mild summers, cool winters with regular freezes, and rain that falls mostly from November through March, and new, relocated, or expanded driveways need a Site Work permit. This guide covers Issaquah's driveway permit rules and how to time paving around the local weather. We did not find a published Issaquah 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 Issaquah 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.

Site Work permit. Issaquah's driveway customer assistance memo says a Site Work permit is required for new driveway construction, driveway relocation, or driveway expansion, and the size of the project sets the stormwater requirements. The site plan must show the existing and proposed driveway, nearby utilities, and the proposed grade, which cannot exceed 12 percent under the Issaquah Street Standards unless a deviation is approved.

Issaquah weather and the best time to pave

Issaquah does not have its own NOAA normals station, so we use nearby Renton Municipal Airport. Its 1991 to 2020 normals show about 34.7 inches of rain a year. November is the wettest month at about 5.61 inches, and July is the driest at about 0.60 inches. About 22.0 inches falls from November through March.

August is the warmest month, with highs averaging about 78 degrees. Winters bring about 30 nights a year at freezing or colder, and January highs average about 48 degrees.

Our tip for Issaquah homeowners: summer is the best window for paving and sealcoating, since most rain falls from November through March. Sealcoat needs dry days to cure, so watch the forecast in spring and fall.
