Building Resilience to Coastal Hazards and Climate Change in Hawaii
April 2019
From May 2016 until April 2019, the Hawaii Department of Land and Natural Resources and the Office of Planning partnered with the University of Hawaii Sea Grant College Program to create three tools that support adaptation at the local level: an interactive data map—the Hawaii Sea-Level Rise Viewer, and two guidance documents—Integrating Coastal Hazards and Sea-Level Rise Resilience in Community Planning and Guidance for Disaster Recovery Preparedness in Hawaii. Much of Hawaii’s population and development exist on low-lying coastal plains that are vulnerable to erosion, flooding, and inundation. Building on the state’s 2017 Hawaii Sea Level Rise Vulnerability and Adaptation Report, the complementary tools are aimed at helping communities better prepare for future sea-level rise and other climate change impacts.

Texas 2019 Coastal Resiliency Master Plan
March 14, 2019
The Texas General Land Office (GLO) updated Coastal Resiliency Master Plan provides a framework for the protection and adaptation of coastal infrastructure and natural resources across the most vulnerable regions of the Texas Gulf coast. The Resiliency Plan adopts the most current storm surge and sea level rise models to determine the implication of projected climate impacts, coastal hazards, and prioritization of these projects. The priority issues of concern identified for resilience planning on the Texas coast focus on degraded or lost habitat, beach and dune erosion, storm surge, coastal flooding, impacts on water quality and quantity, loss of marine and coastal resources, and shoreline debris.

Mexico Beach, Florida - Floodplain Ordinance 712
February 5, 2019
Mexico Beach is on the Gulf of Mexico in Bay County, Florida and faces climate enhanced hurricanes, coastal storm surge, sea level rise and flooding impacts. In October 2018, Hurricane Michael, a Category 4 storm, made landfall in Mexico Beach demolishing 70% of the town’s homes. The coastal community has amended the Federal Emergency Management Agency (FEMA) flood zones maps to reflect storm surge flood levels and high risk floodplain areas as implicated by Hurricane Michael flooding. An ordinance has been adopted in which new construction in Mexico Beach must be elevated at least a foot and a half higher than FEMA's base-level flood predictions in both the region’s 100-year and 500-year floodplains.

Rigorously Valuing the Role of U.S. Coral Reefs in Coastal Hazard Risk Reduction
2019
This report issued by the U. S. Geological Survey and the U. S. Department of the Interior quantifies the value of U. S. coral reefs in protecting people and infrastructure from coastal hazards that will be exacerbated by climate change and sea-level rise including extreme weather events, flooding, and erosion. The report is intended to inform stakeholders and decision-makers of the value of coral reefs in reducing risk from coastal hazards, and to provide quantitative data that can be used to consider the role coral reefs should play in adaptation and risk mitigation planning.

Mainstreaming Sea Level Rise Preparedness in Local Planning and Policy on Maryland's Eastern Shore
January 2019
The Eastern Shore Land Conservancy partnered with the Georgetown Climate Center (GCC), the Eastern Shore Regional GIS Cooperative, and the University of Maryland Environmental Finance Center for this analysis on sea level rise preparedness in Maryland’s Eastern Shore region. GCC offers a discussion of strategies related to floodplain, zoning and regulatory standards to support sea level rise and coastal flooding resilience policies and decision making.

Northeast Florida Regional Resilience Exposure Tool
The Regional Resilience Exposure Tool (R2ET) is an interactive mapping tool that illustrates current and projected coastal flooding risks to resources in the Northeast Florida region. The types of flooding mapped are FEMA flood hazard zones, storm surge, depth of flood at defined storm occurrence intervals, and sea level rise at defined water levels. Users can select data layers for resources to overlay on flooding layers including critical facilities, priority wildlife species, and vulnerable populations.

Sea-level Rise: Projections for Maryland 2018
2018
Maryland’s shoreline and coastal bays are highly vulnerable to sea-level rise (SLR), causing shoreline erosion, deterioration of tidal wetlands, saline contamination of low-lying farm fields, "nuisance” tidal flooding, and more. Fulfilling requirements of Maryland’s Commission on Climate Change Act of 2015, this report provides updated projections of sea-level rise expected into the next century along Maryland’s coast. The probabilistic SLR projections presented in the report offer a scientifically sound and readily applicable basis for planning and regulation, assessments of changes in tidal range and storm surge, development of inundation mapping tools, infrastructure siting and design, and identification of adaptation strategies for high-tide flooding and saltwater intrusion.

Resilient Boston Harbor
October 17, 2018
The plan to develop a climate resilient Boston Harbor in the City of Boston, Massachusetts offers strategies for Boston's 47-mile shoreline that will increase access and open space along the waterfront while better protecting the city during a major flooding event. The plan focuses on green infrastructure and natural solutions to lowering the severity of sea level rise and flooding from climate change. “Resilient Boston Harbor” invests in Boston's waterfront with a proposed restructuring of Fort Point Channel, and development of coastal protection from East Boston to the Dorchester shoreline.

CA AB 3012 State Coastal Conservancy: grants: climate change projects
September 21, 2018
AB 3012 authorizes the State Coastal Conservancy to address climate change impacts on California’s coastal resources through funding projects that reduce greenhouse gas emissions, address extreme weather events, sea level rise, storm surge, beach and bluff erosion, salt water intrusion, flooding, and other coastal hazards that threaten coastal communities, infrastructure, and natural resources.

Climate Ready Boston Coastal Resilience Tracker
September 2018
The City of Boston, Massachusetts is implementing many coastal resilience projects through the Climate Ready Boston program. This project tracker maps and describes a number of these progressive approaches to coastal resilience. The projects included in this tool are recommendations from the coastal resilience solutions plans for East Boston, Charlestown and South Boston.
