Riley’s Is Our Last Name
This isn’t a franchise or a corporate paving company. When you hire Riley’s, you’re working directly with the family whose name is on the truck. That kind of accountability doesn’t come from a corporate handbook — it comes from 30 years of building a reputation one job at a time.

You’ll Always Know What to Expect
Clear quotes. No surprise charges. Upfront communication about scheduling and timelines. We know your time matters, and we treat it that way.

Local Knowledge That Shows Up in the Work
We know Colorado soil and what Centennial’s climate does to pavement over time. That’s the kind of expertise that only comes from decades of working in this market, and it’s the difference between pavement that lasts and pavement that needs to be redone too soon.

Centennial sits on the Front Range plains at roughly 5,800 feet, on the swelling clay soils that define the Denver south metro. Much of the area is underlain by clay-rich plains soils and, in places, claystone bedrock of the Denver Formation. These soils swell when they take on moisture and shrink as they dry — often unevenly across a single lot. That movement is the root cause behind three of the most common driveway failures here: the low spot that forms at the garage apron, edge cracking over disturbed fill, and the slow differential heaving that opens hairline cracks into structural ones.

Building for that subgrade isn’t optional, it’s the whole job. Riley’s engineers base depth, compaction, and moisture control for expansive soil rather than placing a standard plains spec. In newer subdivisions — Greenfield, Smoky Ridge, Willow Trace — builder fill is frequently less compacted than native subgrade, so we compact well beyond the driveway edge and build a thicker base shoulder to keep edges from dropping. Where drainage or slope demands it, we cut a sub-drain or re-grade the base before any asphalt goes down.

Most homeowners won’t need a permit, but it depends on what changes. The general rule:

• Standard repaving in the same footprint — No permit required. Same dimensions, same approach, same drainage.
• Widening the drive, adding a parking pad, or a new curb cut — Likely triggers a permit and an impervious-surface review through the Centennial Building Division. The City and Arapahoe County track impervious coverage on lots that drain into the Cherry Creek and South Platte watersheds, and a footprint change can push a lot over its allowable coverage.
• Drainage modifications — Reviewed for stormwater compliance before work proceeds.
• Commercial work — May add Arapahoe County Public Works review for stormwater and ADA compliance on top of the City process.
• Unincorporated Arapahoe County pockets — Fall under County rather than City jurisdiction, with slightly different access and permit requirements.

For any project that touches the footprint, drainage, or a shared element, Riley’s flags the requirement before quoting, confirms the impervious calculations, and manages the Building Division and County process so the work clears review the first time. HOA architectural approval is handled in parallel where material, footprint, or apron changes require it.
