This analysis assesses the current conditions and projected trends for the Narragansett Bay, a watershed that spans Rhode Island and Massachusetts and is home to 1. 95 million people. The research is the culmination of multiple years of study by universities, organizations, federal partners, and agencies in Massachusetts and Rhode Island. The results are presented in a shorter summary document and a 500-page technical report. In addition to other stressors including water quality and pollution, urbanization, and changes to habitats, the researchers look at the impacts of climate change now and in the future.
The Regional Planning Association (RPA) – for the New York, New Jersey, and Connecticut region – developed this report on coastal climate change adaptation strategies and governance – responding to climate impacts projected for the area such as sea level rise, extreme storms, and severe flooding. According to the report, more than 20% of the region’s municipalities (167) face a future of coastal flooding (either intermittent from storms or permanent from sea level rise). Along with the report, RPA is recommending a new Regional Coastal Commission to help implement adaptation solutions across state lines, produce a regional coastal adaptation plan, and “award funding from new adaptation trust funds” – among other goals.
Utilizing GIS tools to overlay flood risk maps with Annapolis’ many historical sites, the interactive web-based resource help users to understand the threat to their community through images and story mapping. Spurred by the state’s 2008 Climate Action Plan, which assessed what approach (protecting, retreating, or abandoning) was most appropriate for coastal communities threatened by sea level rise, this tool brings together experts in planning, architecture, engineering, and historic preservation.
East Boston and Charlestown, Massachusetts are coastal communities that face significant vulnerability to sea-level rise and coastal flooding. Created with the support of the Commonwealth of Massachusetts and the Barr Foundation, this report describes local climate risks, and provides short- and long-term resilience strategies for these areas. This is the first neighborhood coastal resilience plan to be implemented from the Climate Ready Boston plan and initiative.
The Oregon Department of Transportation (ODOT) green infrastructure solutions for resilience documented in this report are the result of a Federal Highway Administration (FHWA) sponsored pilot project. ODOT analyzed how green infrastructure can help protect the Oregon Coast Highway (US 101) from the impacts of extreme storms and coastal bluff erosion. Through this study ODOT explored the use of nature-based design solutions to protect coastal transportation infrastructure from these climate enhanced impacts.
In 2017, New Hampshire passed a new law, New Hampshire Revised Statutes § 79-E:4-a, that enables municipalities to create a tax incentive program to encourage resiliency in coastal areas. Municipalities can establish “Coastal Resilience Incentive Zones” (CRIZ) in their jurisdictions to grant property owners tax relief for undertaking “resilience measures” for qualified properties or structures identified as impacted by storm surge, sea-level rise, or extreme precipitation projections.
PLAN Hermosa, for the City of Hermosa Beach, California, sets the overall policies and priorities to manage its structural, environmental, social, and economic resources. Climate change is a priority issue addressed in the plan, with a focus on the impacts of sea level rise and extreme heat.
The Maine Flood Resilience Checklist is a non-regulatory self-assessment tool that allows coastal and inland communities of all sizes to evaluate their vulnerability to flooding and sea level rise, examine areas where current policy and action could use improvements to better address the vulnerabilities, and identify specific strategies and actions to enhance flood resilience. The Checklist is designed to be completed through an interdepartmental, facilitated discussion between decision-makers and key municipal planning, management, emergency and enforcement staff.
According to the Union of Concerned Scientists (UCS), hundreds of coastal communities in the U. S. have, or can expect to have, chronic and disruptive flooding inundation from sea level rise in the next few decades. This study identifies all of these communities that will experience enough severe flooding to require either large investments to defend or accommodate sea level rise, or, have to retreat and relocate. The analysis also identifies the “response time” remaining before such flooding occurs, and therefore gives affected communities perspective on the time they have to prepare.
The City of Portland, Maine created the Bayside Adapts initiative to work with community members and organizations to adapt the Bayside neighborhood of downtown Portland to climate change impacts. The initiative includes two completed projects – the Bayside Adapts Design Challenge and the Sewer and Stormwater System Data Gap Analysis – which address the impacts of sea level rise, storm surges, and increased intense rainfall events in Bayside.
