National Assessment of Coastal Vulnerability to Sea-Level Rise: Preliminary Results for the Atlantic Coast
1999
One of three national assessments of U. S. coastal regions conducted in the late 1990's, this assessment focused on the Atlantic coastline, while the other two focused on the Gulf Coast and Pacific coastlines. The overall goal of these studies was to identify those portions of the U. S. coastal regions at risk and the nature of that risk (e. g. , inundation, erosion, etc. ). The long-term goal of this study is to predict future coastal changes with a degree of certainty useful for coastal management, following an approach similar to that used to map national seismic and volcanic hazards.

Rising Seas, Coastal Erosion, and the Takings Clause: How to Save Wetlands and Beaches Without Hurting Property Owners
1998
This law review article discusses ways in which states can protect their public trust lands from sea-level rise while remaining respectful of property owners' rights and investments. The article examines land use planning options by which coastal states might retain some of their public trust tidelands 'in perpetuity' no matter how much the sea rises, at least in areas that have not yet been developed.

City of Marina, California Urban Growth Boundary Initiative
November 2000
In November 2000, the City of Marina approved an update to add an Urban Growth Boundary (UGB) to its city General Plan and Local Coastal Program (LCP) to prevent urban sprawl and to preserve undeveloped land near the coast. The main purpose of the UGB Initiative is to restrict land within the UGB to open space and recreational uses until at least December 31, 2020 (when the current initiative expires, unless it is extended by the city). Low-density zones that were mapped along the coast provide the guidance and land-use controls for these areas. While the UGB and low-density zones were not established for the explicit purpose of managed retreat, they can serve as an example of land-use and zoning tools other municipalities could consider to conserve coasts, natural resources, and other open spaces in the face of sea-level rise and erosion.

Sea Level Rise and Global Climate Change: A Review of Impacts to U.S. Coasts
February 2000
This early report, published by the Pew Center on Global Climate Change (now Center for Climate and Energy Solutions, C2ES), describes the threat that sea level rise poses, and identifies the specific types of impacts this phenomenon will likely have. The state of understanding of the impacts on U.S. coasts is reviewed, and impacts described include inundation of wetlands and lowlands, coastal erosion, increased vulnerability to flooding, and salinization of the water supply.

FGDC GeoPlatform Website
The Federal Geographic Data Committee (FGDC) GeoPlatform website provides access to federally-maintained data and resources related to coastal flooding, sea level rise, and their impacts. The website also provides data from government partners (state, tribal, regional and local) and non-governmental organizations. Platform users can access available data and share customized maps through web browsers and mobile applications.

Connecticut Coastal Hazards Viewer
The Connecticut Coastal Hazards Viewer is designed to allow users access to several pertinent suites of data for coastal Connecticut. Presented here are data representing sea level rise, high-resolution coastal elevation, hurricane storm surge, coastal erosion, and environmental observations such as tides, water quality, waves and currents.

Lessons Learned from Delaware Lidar
A case study of Delaware's efforts to obtain LiDAR elevation maps of its coastline and the lessons that can be learned from the process, this short report may be useful to other states or localities looking to assess impacts from sea level rise and storm surge using LiDAR technology. After describing Delaware's need for LiDAR data in its coastal planning process, the authors address the specific lessons the state learned. These lessons relate to the need for properly scoping and defining a LiDAR mapping project, the need for data standardization, and the need to ensure that end users (in this case, planners) are sufficiently competent with information systems to put the elevation data to good use.

Nature Conservancy Coastal Resilience Program
A program from The Nature Conservancy (TNC), Coastal Resilience is dedicated to providing information to communities, planners, businesses and policy makers to help them integrate sea-level rise and coastal hazards into their decision-making, and mitigate both community and natural resources vulnerabilities. The program consists of an approach, a web mapping tool, and a network of practitioners around the world supporting hazard mitigation and climate adaptation planning.

Maryland Coastal Atlas
The Coastal Atlas is an online mapping and planning tool that allows state and local decision-makers to visually analyze and explore data for coastal and ocean planning activities. The site provides shoreline mapping data for shoreline and flood planning in Maryland. The maps are based on erosion, storm inundation and sea level rise data developed from fifty years of observations, and display future shoreline positions up to fifty years in the future. The data available through the Coastal Atlas includes physical characteristics, human uses and ecological resources.

Coastal Zone Management Administration Awards
Coastal Zone Management Administration formula grants and project grants are awarded to assist any coastal state, including those that border the Great Lakes and non-continental U.S. territories, in implementing and enhancing coastal zone management and related programs that have been approved by the Secretary of Commerce.
