Dan Cronin Trenching in Alpine holds CSLB license #649937 under the Trenching (Only) classification, cutting subgrade channels for residential and commercial foundation footings throughout East County. Water-line cuts routed to Alpine Plumbing & Backhoe run through the same trenches the crew opens for footing pours, reducing excavation passes on tight lots along the Alpine Blvd corridor. The equipment yard at Monterey Place stages wheel trenchers, backhoes, and skip loaders sized for local terrain, where decomposed granite and hardpan clay require chain-driven cutting heads over standard bucket excavation. Electrical conduit runs for panel upgrades and meter relocations share trench profiles with Reddy Electric, coordinating depth-to-cover requirements under California Electrical Code Table 300.5. Standard trench profiles range from 12- to 36-inch widths at depths up to 60 inches, cut to Cal/OSHA Title 8 shoring thresholds for Type B and Type C soils.
