Allred-Collins Business Park

Allred-Collins Business Park is a 135-acre planned industrial development featuring wide industrial collector roads, a significant sewer pump station, and extensive off-site roadway widenings. The project lies in Kearny Mesa and required comprehensive planning for grading, drainage, and utilities. SB&O prepared a tentative subdivision map, cost estimates, feasibility studies, and final designs for major storm drains (72–96 inches in diameter), slope grading, and riparian detention structures. Coordination with CALTRANS involved securing permits for grading near SR-52. Survey tasks included boundary surveys, aerial photogrammetry control, and final monumentation. Construction staking covered mass grading, storm drains, sewer lines, and pump station facilities.
