Increased sea level rise (SLR) due to climate change is a well supported by scientific evidence, and we can expect to see as much as 6ft of SLR by 2100. Surfrider San Diego is working with coastal cities to help them plan and prepare for SLR in a way that protects our precious coastal resources. AB 691 requires coastal cities to plan for SLR by 2019. Many cities in San Diego County are beginning this important process, and Del Mar is the furtherest along. The widest part of the beach in Del Mar is anticipated to disappear sometime between 2030 and 2060, which would significantly reduce and elimate coastal access and recreation. So we need to do proper planning now! Time is of the essense!
Many of the adapation startegies require long planning horizons, so we advocate for early planning, soft solutions that maintain our beaches, setting community priorities, and Sea Level Rise based triggers for adapation strategies. The SLR based triggers protect us from a false sense of security associated with a timeline, since changes could accelerate. If the significant amounts of SLR never happen, then communities will not be bound to pursuing unneeded adaptation strategies. Surfrider San Diego is also currently working in Imperial Beach and Oceanside on this important subject.
