Conserving California’s Coastal Habitats - A Legacy and a Future with Sea Level Rise
March 15, 2018
The Nature Conservancy in California and the California State Coastal Conservancy collaborated on this sea level rise vulnerability assessment of California’s coastal habitats, imperiled species, and conservation lands. This study is the first of its kind to assess the sea level rise vulnerability of all coastal habitats along the entire coast of California, including the San Francisco Bay and Delta. Vulnerability results were used to develop key strategies to protect coastal habitats and at-risk species from sea level rise and other stressors, as well as determine new priority areas to preserve these habitats.

California Coastal Commission DRAFT Coastal Adaptation Planning Guidance: Residential Development
March 2018
In March 2018, the California Coastal Commission (CCC) released Draft Coastal Adaptation Guidance for Residential Development (Draft Guidance) to provide local governments sea-level rise adaptation strategies and example legal and policy tools for residential development. CCC is an independent, quasi-judicial state agency that exercises oversight for activities affecting California’s coast. Through the Draft Guidance, CCC seeks to provide state and local decisionmakers with tools to address the complexities associated with coastal land uses across approaches to residential development that are compounded by variation in the physical environment. Specifically, the Draft Guidance offers a range of legal and policy tools to help facilitate local planning for resilient shorelines and protect coastal resources, including through potential managed retreat strategies. The guidance explores the advantages and disadvantages of many adaptation options, and offers model policy language that could be used to implement best practices. The guidance and model policy language examples may be useful for other coastal jurisdictions planning for or regulating the impacts of sea-level rise on development as the language can be customized and adapted to specific situations and contexts. This guidance can assist coastal managers, local governments, and planners to address climate impacts within their jurisdictions and improve the resiliency of their coastlines and communities.

California Sea-Level Rise Guidance - 2018 Update
March 14, 2018
The Ocean Protection Council’s 2018 update of the California Sea-Level Rise Guidance is designed in support of state agencies and local governments preparation for and adaption to sea-level rise (SLR). The report includes a step-by-step approach to SLR risk analysis, and incorporating these projections into planning, permitting, and investment decisions. Recommended adaptation strategies are given for priorities such as bolstering the resilience vulnerable communities and coastal habitats, and incorporating climate change impacts into project design and coastal planning.

Sea-Level Report Cards: Trends, projections, and processes to aid coastal planning
2018
This tool is created and maintained by the College of William and Mary’s Virginia Institute of Marine Science (VIMS) and provides annual sea-level rise projections and trends for 32 localities across the nation where the National Oceanic and Atmospheric Administration (NOAA) maintains tidal gauges. The report cards are novel in that sea-level rise projections are presented on a local scale and expected to be updated annually (in January) as tidal gauge data becomes available. In comparison, similar data sets are often on a global scale and released after longer time spans.

County of San Mateo, California Sea Level Rise Vulnerability Assessment
March 13, 2018
San Mateo County, California is particularly vulnerable to sea level rise as it is bound by the Pacific Ocean to the west and the San Francisco Bay to the east. This comprehensive 200+ page sea level rise vulnerability assessment offers a highly detailed analysis of the current and future coastal flooding and erosion risks for the County in terms of various sectors and networked infrastructure including critical infrastructure assets, impacts on human mental and physical health, vulnerable populations, and natural communities and ecosystems.

Marin County, California Ocean Coast Sea-Level Rise Adaptation Report
February 27, 2018
Marin County’s “Collaboration: Sea-level Marin Adaptation Response Team” (C-SMART) is a multi-stakeholder, inter-governmental partnership that collaborates to determine sea level rise impacts and adaptation options for the county. This comprehensive analysis from C-SMART presents strategies for increasing resiliency of Marin’s coast with options to accommodate, protect against, or retreat from the threats of sea level rise and coastal hazards.

Patterns and Projections of High Tide Flooding Along the U.S. Coastline Using a Common Impact Threshold
February 2018
The National Oceanic and Atmospheric Administration (NOAA) analyzes "high tide flooding" (also known as "nuisance flooding") in this report, and finds that it is becoming more commonplace due to sea level rise. High tide flooding impacts roads, beaches, parks, and private property, and is generally more disruptive than damaging. However, there are places such as Norfolk, Virginia; San Diego, California; and the U. S Marshall islands where it is currently a serious problem. Even more, with continued sea level rise, flooding is likely to increase.

Hawaii Sea Level Rise Vulnerability and Adaptation Report
December 29, 2017
Hawaii’s Sea Level Rise Vulnerability and Adaptation Report was initially mandated by the Hawaii Climate Change Adaptation Initiative (Act 83, 2014, and expanded by Act 32, 2017). This report represents the first state-wide vulnerability assessment for sea level rise (SLR) coastal hazards in Hawaii. Statewide and island specific adaptation recommendations are given to help reduce Hawaii’s exposure to sea level rise and increase coastal hazard resilience.

Planning for Change in Chatham County, Georgia
December 21, 2017
Chatham County is vulnerable to sea level rise, flooding, and erosion. Increasing the ability of the county to adequately prepare for and recover from the impacts of climate change are important goals of the Chatham County Savannah Metropolitan Planning Commission (MPC). These goals have expanded into ensuring that all areas of the county are preparing for climate change, including public works, fire departments, hospitals, board of educators, and county engineers. The MPC sees itself as a driver for sustainability and resilience for all sectors in Chatham County. As a result of a 2010 climate change planning workshop, community meetings, and surveys, the MPC released an updated comprehensive plan in 2016 to guide development decisions and promote resilience. An update (Plan2040) is in development, using guidance and lessons learned from the 2016 plan.
