Mountain Road Development & Utility Infrastructure
Problem: A partially developed mountain subdivision needed a full restart — roads, drainage, and a complete water distribution system across steep, rocky terrain adjacent to active public roads.
Solution: Rock excavation, road and ditch construction, slope grading, and phased utility installation across a 27-lot development, with ongoing geotechnical coordination for a summit bulk water storage tank.
Skills Used: Rock excavation, mountain grading, erosion control, water main installation, retaining wall preparation, geotechnical coordination, traffic and safety management.
A Texas-based land developer acquired a stalled 27-lot mountain subdivision in Conifer, Colorado after the original developer was unable to complete the project. CJB's Excavation was engaged to restart construction from the ground up — roads, drainage, and a full water distribution system — across a technically demanding mountain site.
This project required rock excavation on a steep mountain slope directly above an active public road. During blasting and breaking operations, controlling material movement — including large boulders — was non-negotiable. The development also required a bulk water storage tank at the summit, served by a water main running the full length of the site with individual meter pits at each of the 27 lots. Three large retaining walls are planned for a steep hairpin turn, and geotechnical boring across near-vertical rock faces is required before the tank pad can be designed. Jefferson County's seeding window adds an additional scheduling constraint for slope stabilization.
CJB's Excavation established the main drive lanes, cut roadside ditches on the uphill side, and graded all slopes for seeding and erosion blanket installation. Rock excavation near the public road was executed with strict safety procedures to protect passing traffic. The team is currently building access routes to near-vertical rock faces to position boring equipment for geotechnical investigation — a prerequisite for the water tank foundation design. Water main installation, booster station connections, and lot meter pits are planned across all four project phases. This is an active, evolving project expected to span 18 to 24 months, with CJB's on site throughout.
Roads are cut in, slopes are graded, and the project is approximately 25% complete with zero safety incidents. The developer has a reliable, experienced contractor managing a scope that demands both heavy civil capability and mountain terrain expertise — and the confidence that comes from working with a team that has done this before.
