Locally in Marin County, the Quarry has responded to levee failures in Novato near Rowland Boulevard and Hamilton Field, hillside slides in Fairfax and Larkspur, and flooding in downtown San Anselmo.
On a broader scale, the Quarry is a major supplier of materials for the levee system in the Sacramento-San Joaquin Delta.
The Quarry was called upon to carry out the emergency repair of 29 levees in the Delta, whose collapse would have devastated not only the region but the state’s water supply. The Delta is home to thousands of residents, critical agricultural resources, and many avian and aquatic species.
