Parking Lot Paving in Ontario, CA

Parking lot paving in Ontario has to account for the region's freight economy. Ontario International Airport is a major cargo hub for FedEx and UPS, and the city sits where Interstate 10, Interstate 15 and State Route 60 meet. That means many lots here see delivery trucks, box vans and semis alongside customer cars. A lot built only for cars will rut and break up along truck routes, at dumpster pads and at loading areas within a few summers.

Designing the section

HomeGuide recommends 4 inches or more of asphalt for commercial lots and heavy wear. In practice we often split a lot into zones: a standard section for parking stalls and a heavier section, or concrete pads, where trucks turn, stop and load. Trash enclosures are a common failure point because the truck's front wheels land on the same square of asphalt every week; a concrete pad there usually pays for itself.

Drainage

Ontario gets only about 11.6 inches of rain a year, but it arrives in a handful of storms. Lots that pond after those storms lose their base and start to pothole. We check the existing grades, inlets and gutters and set slopes so water moves off the pavement. Many newer commercial sites have stormwater features in their approved plans, so we work to the existing drainage design and do not reroute water without the owner's engineer.

Keeping the business open

Most lots can be paved in sections. We map out phases so customers, tenants or residents always have an entrance and some parking, and we schedule noisy work around business hours where we can. Fresh asphalt in summer heat needs time to cool before traffic, so phases are planned with that in mind.

Reconstruction, overlay or repair?

Not every worn lot needs to be torn out. If the base is solid and the problems are surface cracking and oxidation, a milled overlay can give you a new surface for less. If there are areas of alligator cracking and potholes, those sections are cut out and rebuilt first. We walk the lot with you and mark which areas need which treatment, so the quote reflects the actual condition.

Striping and accessibility

A new or resurfaced lot needs a new layout. When restriping, the 2010 ADA Standards apply to accessible stalls, aisles and signs, and we lay out the lot to those dimensions. Striping is quoted as its own line.
