Mar’s other concern is the information gap about sea level rise. Supervisor Mar says that funding remains a hurdle, and he is looking for ways to raise revenue. “Sea level rise could bring other problems such as flood and erosion, and it’s better to take preventive action.” she said. San Francisco Supervisor Katy Tang has organized community meetings about the Ocean Beach Master Plan. “I hope the government could put every cent in the right place as well as shorten the duration of the construction.” “The budget to renovate the highway is all from taxpayers,” she said in Chinese. Wu says she’s more concerned about the cost and length of construction time for the Great Highway. Wu, who has lived on 18 Street in the Sunset District, which borders Ocean Beach, for over 15 years, says she believes sea level rise will not affect residents in the short term. Part of the plan is to plant more vegetation along the shoreline to further buffer against rising seas and reduce erosion. Grant, the program manager with SPUR, said the upper part of the Great Highway is frequently closed because sand dunes often spill onto the road. Climate Central also found that more than 700 housing units and more than $1 billion in property are located below the three feet water line. The analysis found that the cumulative risk of at least one flood exceeding three feet - historically, record floods in the area have reached this level - increased from 27 percent in 2030 to 87 percent by midcentury. Sea level rise, coupled with high tide and storm surges, increase the risk of floods and cause them to be more frequent and severe, according to new research released this week by Climate Central, a research and journalism organization. In California, the sea level is expected to rise by 16 inches by mid-century and 55 inches by the end of the century. Global warming is driving the rapid melting of the Antarctic and Greenland ice shelves, and causing oceans to rise. “The plan also helps to protect the overall ecological environment and to make residents in the Sunset and Richmond districts safe.
“The Ocean Beach Master Plan is important to prevent the Pacific Coast from sea level rise and erosion,” he said. San Francisco Supervisor Eric Mar, who was part of the plan’s advisory committee, says he has been working with the city and public to raise awareness of sea level rise threats. Under the plan, the Great Highway would be re-routed and its width reduced.īenjamin Grant, program manager of San Francisco Planning and Urban Research Association (SPUR), said “reducing the size of the road would give the beach more space to erode naturally” and “the closure area would be rebuilt into an artificial beach.” It offers a vision for how the to adapt to sea level rise in this part of the city, but many of the area’s residents are in the dark about the changes. Rather than building bigger levees or seawalls, the plan calls for a planned retreat from the water. In order to protect the beach, several government departments, including the California State Coastal Conservancy, launched the “Ocean Beach Master Plan,” a comprehensive strategy to address sea level rise, protect infrastructure, restore coastal ecosystems and improve public access. The road was closed for nearly a year, while the city installed a 425-feet stone revetment - a sloping structure to buffer against waves. In 20, storms brought high winds and crashing waves that caused major erosion and deterioration of the southbound section of the Great Highway that connects the northwestern and southwestern parts of the city.
