Update on Landslide Near North Marin Aqueduct

(Updated June 20, 2023) We continue to assess the landslide along Redwood Blvd. near Olompali State Park and potential impacts to the North Marin Aqueduct. Our current assessments have not found significant issues and we have resumed operation of the aqueduct to accommodate demands as of late-April. We have special operational and communications protocols in place with partner agencies in case there is an immediate need to shut down the pipeline and we have ordered spare sections of pipe in case an emergency repair is needed. Caltrans has begun repair work of the landslide area consisting of a new retaining wall. We plan further assessments in coordination with this work’s completion and in the event that we find impacts to the aqueduct that would affect operation, we will update through a website news story. We appreciate the effort from our customer to curtail outdoor irrigation back in April during the early stages of the emergency when the aqueduct was shut-off and water for the service area was solely supplied by Stafford Lake Treatment Plant.
