Accept informational report regarding the issuance of Emergency Coastal Development Permit EM_2025-0004 (Caltrans) to replace a failed 5-foot diameter culvert with an 8-foot diameter culvert at post mile marker 0.6 (PM 0.6) on State Route 1 (SR 1), located at the intersection of State Route 1 (SR 1) and Old State Highway (CR 501A).

Previous Board/Board Committee Actions:
In 1991 the Board adopted Division II of Title 20 of Mendocino County Code through Ordinance No. 3785. Included in Division II is Section 20.536.055 which allows Permits for Approval of Emergency Work. In cases of a verified emergency, temporary emergency authorization to proceed with remedial measures may be given by the Director or his or her designee until such time as a Coastal Development Permit application is filed. The Director shall report in writing to the Board of Supervisors at each meeting the emergency permits applied for or issued since the last report, with a description of the nature of the emergency and the work involved. The report of the Director shall be informational only. The decision to issue an emergency permit is solely at the discretion of the Director. Notice of emergency permits shall be provided by phone or letter to the California Coastal Commission within three (3) days, following issuance of the emergency permit.
Summary of Request:
The emergency is the result of a large sinkhole developed in the roadway at the intersection of Old State Highway and State Route 1. After inspections, it was determined that the sink hole was caused by the failing culvert. Heavy winter rains during late January/early February caused sudden, unexpected damage to the roadway at the intersection of State Route 1 and Old Stage Road in Gualala (post mile 0.6 on SR 1). A large sink hole developed due to a failed, separated culvert. The culvert conveys China Gulch to the Gualala River estuary. Caltrans Maintenance crews made temporary repairs to the roadway to refill the sink void and repave; however, this is not sustainable as there is ongoing movement and a high risk for sudden road collapse. The roadway is in imminent danger of further damage and the traveling public. Immediate action is required to prevent or mitigate the loss or impairment of life, health, property, and essential services. Caltrans issued a Director’s Order in order to obtain emergency funding for this project. The CA Department of Transportation (Caltrans) has an emergency project on MEN 1 at post mile 0.6. A large sinkhole developed in the roadway at the intersection of Old State Highway and State Route 1. After inspections, it was determined that the sink was caused by the failing culvert. The project proposes replacing the existing 5-foot diameter culvert with an 8-foot diameter culvert with baffles. The existing culvert at this location, China Gulch, is listed as a total barrier to anadromous salmonids.
The emergency permit was issued on October 3, 2025, and becomes null and void at the end of sixty (60) days. Prior to expiration of this Emergency Permit, the applicant shall submit a standard Coastal Development Permit application for the work authorized by the permit.
