Kleinfelder provided geotechnical engineering and environmental permitting services during the preliminary design, final design, and construction phases of the Tustin Avenue/Rose Drive overcrossing. The project was completed as part of the OC Bridges program. The Tustin/Rose grade separation increases driver/pedestrian safety, eliminates delays traffic delays, and improves air/noise conditions.
By demonstrating to MWD that the grade separation project would not adversely affect the pipeline, no design changes were required and the project remained both on-schedule and on-budget. Additionally, by securing
a Revalidation of the Environmental Document on an extremely short deadline, the team avoided significant schedule delays associated with changes to the Environmental Document.
