BACKGROUND/DISCUSSION:
On January 22, 2016, the Director of Emergency Services proclaimed the existence of a local emergency along the Pacifica coastline from Westline Drive to the end of Beach Boulevard due to El Nino storm activity. Extreme wave heights for extended periods of time caused top-of-bluff retreat at several locations along the Pacifica coast and damage to City infrastructure. Since this date, the Director of Emergency Services has proclaimed the existence of other local emergencies along this same stretch of coastline. These emergencies are described below:
• Failure of the sea wall and promenade on Beach Blvd. (in the vicinity of Santa Maria Avenue), which have been repaired, from the January 22, 2016 storm. • The 300 & 400 block of Esplanade experience episodic bluff erosion. In recent years (2016-2018), the bluff erosion has progressed to a point where the erosion is now threatening public infrastructure and utilities.
• Undermining of a seven-foot diameter storm drain outfall and concrete headwall for the discharge of Milagra Creek into the Pacific Ocean in the vicinity of 700 Palmetto Avenue from the January 22, 2016, storm. Construction is scheduled to restart in February of 2021 due to project delays.
• A failure of the seawall and promenade on Beach Blvd. in the vicinity of Santa Rosa Avenue and the Pier was discovered on December 16, 2020. Ocean waves, king tides, and high swells undermined a portion of the sea wall and created a large void (25’x25”) between the pier abutment seawall connection, affecting the sidewalk and promenade.
City staff and contractors stabilized and repaired the large void on January 22, 2021.
The sidewalk and promenade restoration were completed on February 22, 2021.
Monitoring of the repaired area is on-going.

• On December 29, 2020, another failure of the seawall occurred approximately 150-200 feet north of the intersection of Beach Blvd. and Santa Rosa Avenue. A void, approximately 10’ deep by 15’ long, was found behind the seawall and was repaired with geotextiles and concrete slurry on January 5, 2021. Full restoration of this section was complete in February 2021. Monitoring of the repaired area is on-going. • On January 14, 2021, a combination of high tides and large waves damaged a forty-foot section of the Pacifica Municipal Pier’s west facing deck and concrete railing. Following this event, the Pier was closed due to safety concerns. City staff requested a structural engineering assessment of the above deck pier elements and a proposed repair and associated cost from a local engineering consultant. This information was provided to the City by the end of March 2021. The pier was reopened on April 2, 2021, but the damaged portion was fenced off for safety reasons. The City is currently moving forward with a repair project and is designing the repair. Construction will be funded by grant money provided through a Senate Bill 129. The City Council approved a resolution on December 13, 2021, to approve the application of the state grant funds for the repair of the pier and the application has been sent to the State Department of Parks and Recreation for processing. On May 13, 2022, the City received a Coastal Development Permit waiver from the California Coastal Commission to perform this work. A bid opening for the repair was held on June 9, 2022, and the City received one bid, which was $2 million above the project budget. Council rejected the bid and authorized the project to be rebid.
The City Council first ratified this proclamation (Attachment 1) at its regular meeting of January 25, 2016. Since that date, additional damage had occurred along Beach Boulevard and Esplanade Avenue as noted above.
Pursuant to Government Code section 8630(c), the City Council must review the need for continuing the local emergency at least every 60 days until the City Council terminates the local emergency. Conditions of local emergency still exist since the City Council first acted to declare a local emergency on January 25, 2016, and since that time staff has brought the continuance of Proclamation confirming the existence of local emergency exists within the Pacifica Coastline from Westline Drive to the end of Beach Boulevard every 30 days with July 10, 2023, being the most recent.
The City is using a combination of city staff, contractors, and consultants to manage the discussed emergency work. Staff will bring recommendations to the Council to end the emergency designation for projects on the list once conditions stabilize and the projects are no longer in need of the emergency designation.
The City Manager recommends that the City Council make a determination that conditions of local emergency continue to exist within the Pacifica Coastline from Westline Drive to the end of Beach Boulevard.
