Paving for Byron Homes, Farms and Yards
Asphalt paving in Byron serves a small, spread-out community 5.5 miles southeast of Brentwood. Byron's 2020 population was 1,140 across 6.52 square miles, and most properties are rural or semi-rural. Average July highs reach about 93 degrees. The typical job is a long driveway, an equipment or truck yard, or the conversion of a dusty gravel drive to asphalt.
Built for heavy use
Rural driveways carry delivery trucks, farm equipment and trailers. We use a thicker base and asphalt section where heavy loads travel and give the road a crown so water runs off.
Heat
Hot summers mean new asphalt stays soft longer. We pave early, keep heavy vehicles off until it cures, and recommend sealcoat once the surface has had a few months to set up.
County rules
Byron is unincorporated, so driveways that meet a County road fall under Contra Costa County Public Works encroachment permits. The County's minimum asphalt driveway section is 2 inches of asphalt over 6 inches of Class 2 aggregate base, and the inspector needs at least two working days' notice before work starts.
Near the airport
Byron Airport, dedicated in 1994, sits 2 miles south of town on 1,307 acres, 814 of them set aside as San Joaquin kit fox habitat. Properties nearby can have their own access and land-use considerations, which we discuss at the estimate.
Long drives and county roads
Many Byron properties sit along long County roads, with driveways that run hundreds of feet to a home or barn. Paving the full length is a large investment, so some owners pave the first stretch from the road, where dust and mud are worst and the County standards apply, and keep gravel farther in. We price both options. Byron's first post office opened in 1878, and some properties have farm roads that have been built up with rock for generations; where that rock is firm and drains, it can become part of the new base. Byron Hot Springs, south-southeast of town, and the airport area have their own access considerations we discuss at the estimate.

Byron Questions
Can you pave a truck or equipment yard in Byron?
Yes, with a heavier base and asphalt section sized for the loads.
Do I need a permit to connect my driveway to a County road?
Yes, Contra Costa County requires an encroachment permit for work in its road right-of-way.
Is gravel or asphalt better for a long rural drive?
Gravel is cheaper up front; asphalt cuts dust, mud and regrading. We price both if you are deciding.
Can I pave just part of my long drive?
Yes. Many owners pave the first section from the road and keep gravel beyond. We transition cleanly between the two.
Is old farm rock good enough for a base?
If it is firm and drains, often yes. We test it before relying on it.
