LG Equipment in Alpine operates from 3220 Alpine Blvd as a site-preparation and utility-infrastructure contractor, holding general contracting licenses in both California and Arizona. With more than 70 years of combined crew experience, the firm handles grading, trenching, and underground conduit installation — groundwork phases that typically conclude when Arrow Fence sets perimeter posts and rails on the finished grade across Alpine projects. Federal contracting credentials under NAICS code 238910 qualify LG Equipment for government site-preparation bids alongside its private-sector residential and commercial work. Finish-grading precision on Alpine Blvd commercial pads requires accurate elevations before vertical construction begins, a foundational accuracy that determines the quality of every subsequent trade including the protective exterior coatings applied by JT Coatings on Marshall Court. Project scopes at the highest tier include rough and finish grading to engineered pad elevations, utility-trench excavation with bedding material and backfill compacted to agency-specified density standards, and concrete-foundation formwork for commercial building pads.
