Founded in 1926 in Lakeside, Hazard Construction Co holds CSLB License #750542 (A/C-31, General Engineering and Construction Zone Traffic Control) and operates from its Vine Street headquarters, which the firm has owned since 2019. A century of San Diego infrastructure work includes grading for segments of Interstates 5, 8, 15, and 805, construction support for the Cross Border Xpress binational terminal, and finish materials for large-scale site development supplied through partners at Alpine Landscape Materials on Tavern Road. The 2023 AGC Build San Diego Unique Small Project Award recognized the Creekside Park & Franklin Ridge linear park, and a 2025 AGC Award for Excellence in Heavy/Highway Construction followed for the Gillespie Field Runway 09R/27L rehabilitation. Current public-works contracts span I-805 improvements and SR-163 safety upgrades, projects whose underground mechanical systems coordinate with contractors at Slayton Mechanical Contractors on Vine Street. The firm's highest-capacity engagements involve full site-development packages exceeding 300 acres—including mass grading, wet-utility installation, and street improvements—for industrial parks serving San Diego County's logistics and manufacturing sectors.
