Accept the Informational Report regarding the issuance of Emergency Coastal Development Permit EM_2026-0003 (Caltrans) to address a landslide between two terraced sections of Highway 1 by removing slide material, installing a shear pile wall, grading slide material, replacing a guardrail, conducting pavement work, temporarily widening the roadway, and removing vegetation within the slide area, located on State Route 1 between Post Miles 31.0 and 31.5 approximately 3 miles south of its intersection with Philo Greenwood Road (CR 132) near Elk.

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:
Heavy winter rains in February 2026 caused a landslide between the switchbacks on the roadway south of Elk Creek due to oversaturated soil and erosion. Slide debris blocked both lanes of travel on the lower road, and the top of the slide has a risk of regressing to the upper road. The debris was cleared from the roadway allowing one-way traffic control. However, according to Caltrans, the roadway has been undermined and is at imminent risk of further failure. The project would involve removal of the slide material on the traveled way and shoulder, installation of a shear pile wall between the slide and guardrail of the upper road, and removal of failed material on the slide after installation of the shear pile wall. The project would also involve grading the slide material and road shoulder, removal and replacement of an existing guardrail, installation of a new concrete weed mat under the guardrail, pavement work, temporary roadway widening on the upper hairpin turn, and vegetation removal within the slide area. According to Caltrans, failure to act at this location would likely result in slide growth and further damage to the highway leading to full closure of State Route 1 in this area.
The Emergency Permit was issued on October 30, 2026 and becomes null and void at the end of sixty (60) days. Prior to expiration of this Emergency Permit, the applicant must submit a standard Coastal Development Permit application for the work authorized by the permit.
