MCM Utility Services, Inc. on Riverside Drive in Lakeside holds CSLB license #1070956 (C-10 Electrical) and operates as a certified Woman-Owned Business providing commercial, industrial, and low-voltage electrical services throughout Southern California. Underground utility trenching for data, fiber-optic, and power distribution systems runs parallel to the subsurface plumbing and backflow work that Tatum Plumbing Co performs from Woodside Avenue when both trades occupy the same construction site. As an IBEW Local 569 signatory staffing all field crews with union-card journeymen, the service portfolio covers electrical system design, engineering, procurement, and installation for conventional building construction, underground utility distribution, and communication infrastructure. Solar-farm electrical integration and utility-scale interconnection work shares the same medium- and high-voltage distribution expertise that Clayco Electric Inc. Solar Specialist applies to rooftop photovoltaic systems on Alpine Blvd. The highest-specification projects involve complete underground electrical and fiber-optic distribution networks for commercial developments, requiring engineered duct-bank layouts, concrete-encased conduit runs, and transformer-pad coordination with SDG&E interconnection standards.
