Design-Build Emergency Mission Gorge Road Repair – San Diego, CA

The City of San Diego contracted Orion to identify the cause of Mission Gorge Road’s two foot settlement and to design and construct a permanent fix.  Orion quickly determined the cause of the settlement to be a ruptured sewer line 28’ underground. Orion demolished over 2,100 feet of road and landscaped median to access the ruptured pipe via 28ft deep shored trenches. The sewer was placed on bypass and the damaged sections repaired. Because this repair caused major disruptions to local traffic, Orion and its designers worked on an accelerated schedule to get the road back in service. 

Design-Build Hector Avenue Storm Drain Repair – San Diego, CA

The Hector Avenue Storm drain failed during one of San Diego’s largest storms in recent years. When the storm drain failed, the embankment where it was located rapidly eroded and threatened private homes on the above canyon walls. The City of San Diego tapped Orion as an emergency design-builder to mobilize to the site, stabilize the area, and design and construct a permanent fix.

Orion worked with local homeowners and through City easements to access to the steep slopes to remove the storm drain. The area was over-excavated and backfilled with fill soil which was later re-vegetated over a period of several months to prevent future erosion. This project was exceptionally challenging given the storm drain’s location on a steep embankment and the rapid mobilization needed to protect private property.
