Arroyo Seco Road Storm Damage at Milepost 0.75: County Proposed Soil-Nail Wall Repairs

ARROYO SECO, Monterey County — October 29, 2026. A Monterey County road-repair record documents damage at Arroyo Seco Road milepost 0.75 following an atmospheric-river storm on February 13, 2025. In an October 2025 capital-improvement discussion, county staff proposed adding the emergency repair to the road fund’s annual work program.

What was damaged?

The road site is in inland mountainous Monterey County, where storms can destabilize slopes and roadway edges. Public Works identified two storm-related projects for additional funding consideration: one at Arroyo Seco Road and another on Fern Canyon Road near Carmel Highlands. These are geographically separate repair locations.

What method did engineers recommend?

The staff report recommended soil-nail retaining walls to stabilize damaged sections. The combined estimated cost for the Arroyo Seco and Fern Canyon sites was approximately $996,500, proposed to be paid from a county road-fund operational reserve. That amount covered two sites and must not be described as the price of the Arroyo Seco repair alone.

Did a disaster declaration fund the project?

The county said the February 2025 weather event was not declared a local, state or federal emergency. Its proposal therefore relied on county funding, not on a confirmed federal disaster reimbursement.

What is the latest confirmed construction status?

The cited October 2025 committee item is a proposal to add the work to the annual program. It does not confirm completion, contractor payment or that the road is open today. For actual restrictions consult Monterey County road advisories. This is also distinct from the later Timber Fire restriction affecting an Arroyo Seco Road intersection.
