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.

Mid-Atlantic Forest Ecosystem Vulnerability Assessment and Synthesis: A Report from the Mid-Atlantic Climate Change Response Framework Project

October 2018

This U. S. Forest Service report develop provides an assessment of the vulnerability of forest ecosystems in the Mid-Atlantic region and was designed to help resource managers incorporate climate change considerations into management practices. The report synthesizes the best available scientific information on climate change and forest ecosystems, focusing on a study area including 60 million acres of land across eastern Maryland, southern New York, Pennsylvania, New Jersey, and Delaware. Of this area, about 32 million acres are forested.

Changing Tides: How Sea-level Rise Harms Wildlife and Recreation Economies Along the U.S. Eastern Seaboard

August 15, 2016

From the National Wildlife Federation (NWF), “Changing Tides” delineates the risks of sea-level rise to wildlife, recreation, and local economies by outlining key impacts in 15 eastern U.S. states: Florida, Georgia, South Carolina, North Carolina, Virginia, Maryland, Delaware, Pennsylvania, New Jersey, New York, Connecticut, Rhode Island, Massachusetts, New Hampshire, and Maine. NWF also offers policy solutions for both mitigation and adaptation to climate change.

Trends in Extreme Precipitation Events for the Northeastern United States 1948-2007

March 2010

Based on the number and frequency of extreme precipitation events since the release of their 2005 report, entitled "Indicators of Climate Change in the Northeast," the authors sought to update information for this particular indicator in the Northeast, and apply more rigorous analysis to better enable local communities to take appropriate actions.

The Likelihood of Shore Protection Data Set

2009

This site provides the GIS data that was used for the study "State and Local Governments Plan for Development of Most Land Vulnerable to Rising Sea Level along the U. S. Atlantic Coast," published by James Titus. The GIS data are available in three formats: grid, polygon shape files, and vector shape files. This data identifies shoreline development and areas that will be vulnerable to sea level rise. .

Delaware 2017 Coastal Inundation Maps

2017

Delaware's Department of Natural Resources and Environmental Control (DNREC) and the scientists from Delaware Coastal Programs have developed Sea Level Rise (SLR) inundation maps for the state as an online interactive tool. The maps show the possible impacts of inundation based on various SLR scenarios for Delaware’s waterways and watersheds.  The maps are a representation of inundation based on local Mean Higher High Water (MHHW), which is the long-term average of the higher of the daily high tides.

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.

Recommendation of Sea Level Rise Planning Scenarios for Delaware: Technical Report

2017

The Delaware Department of Natural Resources and Environmental Control (DNREC) first developed Recommended Sea Level Rise Scenarios for Delaware in 2009.  In 2016-2017, a new Delaware Sea Level Rise Technical Committee was convened to update the scenarios based on the latest scientific research and modeling. Led by Delaware Geological Survey and DNREC Delaware Coastal Programs, the Committee and these sea-level rise (SLR) planning scenarios respond to 2013 Executive Order 41 - which requires Delaware state agencies to factor SLR into capital improvement projects and land use decisions, and for DNREC to periodically update SLR scenarios with the best scientific data available.

Coastal Inundation Toolkit

The Coastal Inundation Toolkit was developed by the Digital Coast Partnership Group to help communities understand and address coastal inundation issues - where water covers what is normally dry land. Information and resources are organized into 5 stages: understanding coastal inundation, identifying community risks and vulnerabilities, creating inundation maps, communicating risks and vulnerability, and discovering what others are doing to address inundation. For each of these 5 areas, explanations and guidance are provided with links to the specific resources available from Digital Coast to support that specific step in the process, making this a user-friendly way to support assessments and planning for sea level rise and extreme weather events.

Climate Change Tree Atlas

October 26, 2010

The Climate Change Tree Atlas helps determine current and future suitable habitat and distribution of 134 tree species in the Eastern United States based on current climate and projected suitable habitat for the year 2100. The Atlas provides detailed information on environmental characteristics defining these distributions for each species, and can be used to develop large-scale projections of species responses to climate change. By taking current distributions of tree habitat in the U. S.
