Castro Valley doesn’t have its own city hall. It’s the largest unincorporated community in Alameda County, which means driveway and paving rules here come from the County, not a local city government the way they do in Walnut Creek or Dublin. That single fact changes who homeowners and businesses need to talk to before starting a paving project, and it’s often the first thing that trips people up.
Huff General Engineering provides asphalt paving services throughout Castro Valley, CA. Based nearby in Walnut Creek, we work with homeowners in the canyon neighborhoods, HOA boards, and business owners along the Castro Valley Boulevard corridor.
Our services include driveway paving, private road paving, parking lot paving, asphalt repair, crack repair, and sealcoating.

Castro Valley sees mild, wet winters and warm, dry summers, with somewhere around 20 to 21 inches of rain a year, most of it falling between November and March. On its own, that’s a pretty normal Bay Area pattern. What makes it matter more here is the terrain. A lot of Castro Valley sits on hillsides and in canyon pockets, so rain that would just soak into a flat yard somewhere else tends to run downhill fast, right across driveways and private roads.
Castro Valley is really a collection of neighborhoods spread across a valley and its surrounding hills, so we plan work around where a property actually sits rather than treating the whole area as one flat job site.
A driveway in the hills of Five Canyons and a storefront lot near the Boulevard call for different equipment, different scheduling, and often different grading work, even though they’re only a few miles apart.
For anything that touches a county road, you’d go through the Alameda County Public Works Agency, since Castro Valley is unincorporated and doesn’t have its own separate city permit office. We help figure out what applies to your project before we start.
Usually yes. Pooling water at the low point of a sloped driveway is almost always a grading or drainage issue rather than a problem with the asphalt itself, and it’s something we look at closely on any hillside property.
Cost depends on the size of the driveway, how steep or sloped the lot is, the condition of what’s already there, and how easy the site is for our equipment to reach.
Yes. Huff General Engineering paves driveways in Castro Valley’s canyon neighborhoods and parking lots along the Boulevard corridor, using the same crews and the same standards for both.
