1. You request an estimate — Call 303-437-0294 or submit the form. We respond same business day during paving season.
2. We walk the site in person — Every foothills job is assessed on-site. We measure slope, evaluate access, check drainage, and confirm whether the property falls under Town of Morrison or unincorporated JeffCo jurisdiction.
3. You receive a written, line-item bid — Detailed scope, materials, square footage, drainage features, and timeline.
4. We confirm permits and access requirements — JeffCo Access Permits, Town of Morrison reviews, and any HOA approvals are identified and filed before mobilization.
5. Crew arrives with the right equipment — Compact equipment for hillside access, full-size for commercial. Same foreman from quote to close-out.
6. Base, place, and compact — Subgrade re-shaped for drainage, base built to a depth that handles freeze-thaw and slope, hot-mix placed in the right temperature window, compaction to spec.
7. Final walk-through — We walk the surface with you, confirm drainage performs as designed, and address punch-list items. Warranty terms in writing.

Morrison’s geology is a different problem from the plains. Lots in the Bear Creek drainage and unincorporated Jefferson County sit between roughly 5,700 and 6,500 feet on rocky, shallow residual soils over Precambrian bedrock — granite and gneiss — often with decomposed granite and slope colluvium on top and fractured rock close to the surface. Unlike the deep expansive clay of the Denver metro, the foothills challenge is thin soil cover, variable bedrock depth, and slope, all of which demand a different base spec and far more attention to where water goes.

That’s why drainage design carries the job here. Foothills topography channels uphill runoff straight onto every downslope surface, and a driveway built without a crown, swale, or sub-drain becomes a streambed during snowmelt and summer storms, undermining the base from below. North-facing drives compound it by holding snow and ice for days, driving prolonged moisture into the surface. Riley’s re-shapes the subgrade to crown the surface, cuts roadside swales, and installs sub-drains where the slope demands it — then builds the base to a depth tuned to rock and shallow soil rather than a generic flatland section.

Morrison spans two jurisdictions, and getting the right one is the first step:

• Town of Morrison parcels — Reviewed through the Town of Morrison for in-town property.
• Unincorporated Jefferson County parcels — Governed by JeffCo Planning & Zoning.

Beyond jurisdiction, foothills access work carries requirements the plains don’t:

• Access Permit — Required for any new driveway or modification taking access from a county-maintained roadway, or any work within 15 feet of a public road (25 feet of a public arterial). JeffCo Road & Bridge reviews drainage, culvert sizing, plow operations, and sight distance, see the County’s driveway and access requirements.
• Driveway grade — Jefferson County limits private drives to a 10% maximum grade (12% if south-facing for ice-melt purposes), with fire-truck hammerheads required at intervals on longer drives and adequate turning radii built into the layout.
• Grading / earthwork — Slope work may require a separate grading permit or Notice of Intent depending on the volume of disturbance.
• Footprint and drainage changes — Standard in-place repaving generally needs no permit; new or expanded footprints, new curb cuts, and drainage modifications trigger review.

Riley’s assesses slope and jurisdiction before quoting, files the Access Permit and any grading application, coordinates the culvert and drainage spec, and schedules around the approved access plan so the project doesn’t get red-tagged mid-build.
