CalPortland Santa Maria Construction Services

CalPortland Santa Maria Construction Services is the Central Coast construction office of CalPortland Company, a producer of aggregates, asphalt, cement and ready-mixed concrete whose history goes back over 130 years. Located at 1625 E. Donovan Road in Santa Maria, California, the office handles construction work for public agencies and private owners.

Its main lines of work are earthwork, site development, asphalt paving and highway construction. The project list spans private jobs, commercial developments and local roads as well as major Caltrans highway contracts. Because it is part of a materials company, the Santa Maria team can draw on CalPortland asphalt and other construction materials, and it relies on in-house trucking to move material to job sites. Project teams provide planning and coordination support in addition to field construction.

The parent company operates cement terminals, ready-mix plants and other facilities in California, Nevada and Arizona. In 2026 it completed the purchase of Vulcan Materials' ready-mixed concrete assets in the Bay Area and San Diego. Six CalPortland facilities have met the ENERGY STAR Challenge for Industry by cutting energy intensity, and its ready-mix plant in El Segundo received a 2026 Tandem Global Landscaped Project Award for native habitat work.

The Santa Maria office is open weekdays from 9 a.m. to 5 p.m.
