Local Expertise, Limitless Solutions

The staff at Diamond West has worked on numerous public improvement projects throughout Southern California for both public and private sector clients. 

 In fact, several project staff members have direct professional experience as employees for state and local government.

Diamond West employees have considerable experience working with the California Department of Transportation (Caltrans), Metropolitan Transportation Agency (MTA), Regional Water Quality Control Board, Army Corps of Engineers, California Department of Fish and Game and other State and Federal Agencies. We believe our experience from “both sides of the counter” is an immeasurable asset and provides our clients with valuable services such as: thorough understanding of agency processes, applications of various regulations, and close relationships and communication with local agencies.
