LB3 Enterprises Inc in Lakeside is a general engineering contractor on Highway 67 specializing in mass grading, demolition, and large-scale excavation across Southern California and Arizona. GPS grade-control technology and drone-derived topographic surveys guide every cut-and-fill operation to design tolerances, with environmental-clearance protocols on sensitive parcels requiring coordination alongside biological monitors from Advanced Integrated Pest Management on Riverside Drive. Incorporated in 2011, the firm employs 51 to 200 crew members and maintains dual state licenses for projects spanning residential tract grading, landfill-cell expansion, and river-basin habitat restoration. Completed scopes include aggregate-overburden removal for active mining operations and multi-phase landfill airspace creation requiring stormwater compliance, the kind of heavy-civil groundwork that sets the stage for below-grade mechanical runs by Precision Temperature on Woodside Avenue. In-house GPS design capabilities pair drone topographic surveys with Trimble-grade-control receivers on dozers and motor graders, maintaining cut-and-fill accuracy within specified vertical tolerances across multi-million-cubic-yard earthwork balances.
