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.
