CPOA Update – County Community Working Group on SLR Vulnerability Assessment Project and changes to the LCP

At the 2nd meeting of the County Community Working Group on 2/19/25, the project team presented the preliminary findings of the SLR Vulnerability Assessment Study for the Santa Cruz County coastline. The Sea Level is projected to rise 0.6 to 1.0 feet by 2050, and 1.6 to 4.9 feet by 2100 (Statewide average: Intermediate Low – Intermediate High scenarios), CA Sea Level Rise Guidance Policy for 2024. The Consultants evaluated the incremental impact on coastal resources and shoreline protection of each foot (1 – 3 feet) of Sea Level Rise over the next 20 – 30 years, and the potential impact of 4-6 feet of SLR over the following 30 – 70 years (up to 2100). Countywide, there would be approximately 200 structures “at risk” with existing armoring and one foot of SLR, 1,500 structures “at risk” without any armoring. With three feet of SLR, 500 structures would be “at risk” with existing armoring and 2,400 structures would be “at risk” without any armoring. County beaches would be approximately 75 feet narrower on the average with existing armoring. Most vulnerabilities are caused by erosion to residential buildings, with Seacliff, Rio Del Mar and Aptos neighborhoods having the highest number of structures “at risk”.
