Asphalt & Concrete Enterprises (A.C.E.) in Santee's Woodside Avenue industrial corridor holds CSLB license #953331 (A–General Engineering) and DIR registration #1000006255 for prevailing-wage public-works projects. Full-service grading and paving contracts cover rough earthwork, fine grading, asphalt placement, and concrete flatwork, with pre-paving site clearing often requiring the mature-tree removal and stump-grinding services of Liberty Tree Services in Santee. The firm is a member of both the Associated General Contractors (AGC) San Diego chapter and the California Asphalt Pavement Association (CalAPA), and carries California Department of General Services DVBE (Disabled Veteran Business Enterprise) certification. ADA-upgrade scopes include parking-lot re-striping, accessible-ramp construction with truncated-dome detectable warnings, and path-of-travel slope corrections to meet the 2 percent cross-slope maximum under current federal accessibility guidelines. Electrical conduit and junction-box placement beneath planned asphalt surfaces requires pre-pour coordination with the underground rough-in teams at contractors such as Solid Electrical Services on Magnolia Avenue. The heaviest paving scopes involve full-depth asphalt reclamation using Wirtgen W 210 Fi cold-milling machines cutting 14-inch lifts across roadway sections exceeding 50,000 square feet per shift.
