Erosion will worsen as sea levels continue to rise. University of Southern California (USC) Sea Grant funded a study to use the most recent data to update cliff retreat rates statewide. Understanding the processes that drive cliff erosion and quantifying the rates at which they operate are essential for coastal managers and for building resilient communities.<\/span><\/p>\n\n\n\n<\/div>\n      \n      \n    <\/div>\n  \n  \n  \n\n  <\/div><\/div>\n\n\n\n\n  \n    \n\n\n\n\n\n\n<div\n  class=\"cc--component-container cc--rich-text \"\n\n  \n  \n  \n  \n  \n  \n  >\n  <div class=\"c--component c--rich-text\"\n    \n      >\n\n    \n      \n<div class=\"f--field f--wysiwyg\">\n\n    \n  <h3><b>Key Results<\/b><span style=\"font-weight: 400;\">:<\/span><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Provided the first modern, high-resolution erosion rates for about half of California<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Identified hot spots, detected regional and local trends, and validated an experimental cliff top hazard index designed to better direct management efforts<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Journal publications in <\/span><i><span style=\"font-weight: 400;\">Geomorphology <\/span><\/i><span style=\"font-weight: 400;\">and<\/span><i><span style=\"font-weight: 400;\"> Geoscientific Model Development<\/span><\/i><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h3><b>Project Impacts &amp; Application:<\/b><\/h3>\n<ul>\n<li aria-level=\"1\"><span style=\"font-weight: 400;\">Created an online data portal for coastal managers, scientists, engineers, and the public (<\/span><a href=\"https:\/\/siocpg.ucsd.edu\/data-products\/ca-cliff-viewer-guide\/\"><span style=\"font-weight: 400;\">https:\/\/siocpg.ucsd.edu\/data-products\/ca-cliff-viewer-guide\/<\/span><\/a><span style=\"font-weight: 400;\">)<\/span><\/li>\n<\/ul>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Presentations: American Geophysical Union Conference, Scripps Directors Council, AGU Ocean Sciences, Office of Management and Budget &#8211; Executive Office of the President, Osher Lifelong Learning Institute<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Briefings: CA Assemblymember Davies; Staff of US Senator Padilla; Marine Corp Air Station Miramar; City of San Diego Chief Sustainability Officer Shelby Rust Bus\u00f3<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Webinars for staff from California State Parks and California Coastal Commission<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Media attention: front-page articles on the LA Times, San Francisco Chronicle, and San Diego Union-Tribune; features on KQED, KPCC, KPBS, The Weather Channel, The Coast News, Lost Coast Outpost, Pacifica Tribune, and The San Diego Reader<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h3><b>Principal Investigators:<\/b><\/h3>\n<ul>\n<li><span style=\"font-weight: 400;\">Adam Young, Ph.D., University of California San Diego\u00a0<\/span><\/li>\n<li><span style=\"font-weight: 400;\">Mark Merrifield, Ph.D., University of California San Diego\u00a0<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h3><b>Funding: <\/b><\/h3>\n<p><span style=\"font-weight: 400;\">California Ocean Protection Council, 2018-2021<\/span><\/p>\n<p>&nbsp;<\/p>\n<h3><b>Additional Info and Publications<\/b><span style=\"font-weight: 400;\">:\u00a0<\/span><\/h3>\n<ul>\n<li><a href=\"https:\/\/siocpg.ucsd.edu\/cliffs\/\"><span style=\"font-weight: 400;\">https:\/\/siocpg.ucsd.edu\/cliffs\/<\/span><\/a><span style=\"font-weight: 400;\">\u00a0<\/span><\/li>\n<li><a href=\"https:\/\/siocpg.ucsd.edu\/data-products\/ca-cliff-viewer-guide\/\"><span style=\"font-weight: 400;\">https:\/\/siocpg.ucsd.edu\/data-products\/ca-cliff-viewer-guide\/<\/span><\/a><\/li>\n<li><span style=\"font-weight: 400;\">Swirad, Z.
