The Potential Impacts of Global Sea Level Rise on Transportation Infrastructure

October 2008

Prepared by the U. S. Department of Transportation, this report provides a high-level estimate of the net effect of sea level-rise and storm surges to transportation infrastructure on the U. S. eastern seaboard by 2100. The study integrates estimates of eustatic sea-level rise based on IPCC scenarios and digital elevation maps to identify areas that will either be inundated or placed at risk during storms. These estimates do not account for local variations. Based on 9 modeling outputs, from 6cm to 59cm, the study identifies the roads, airports, ports, and rail lines at risk from New York down to Florida, and it provides quantitative data on the extent to which each state in the study area will be affected by sea-level rise.

Caltrans District Climate Change Vulnerability Assessments (2019)

October 2019

Between 2017 and 2019, the California Department of Transportation (Caltrans) produced climate change vulnerability assessments and corresponding GIS mapping tools for each of its twelve districts covering the state to help build resilience through transportation decisionmaking. For each Caltrans district, the assessments include high-level overviews of climate change impacts (summary reports) and detailed technical reports on the processes used to identify relevant climate impacts. The reports and mapping tools are designed to help Caltrans planners understand impacts to the portions of the State Highway System (SHS) and other assets in each district, and plan projects accordingly to ensure resilience under future conditions.

Incorporating the Costs and Benefits of Adaptation Measures in Preparation for Extreme Weather Events and Climate Change (NCHRP Report 938)

2020

This guidebook, Incorporating the Costs and Benefits of Adaptation Measures in Preparation for Extreme Weather Events and Climate Change (Guidebook), provides a comprehensive resource to help transportation agencies incorporate cost-benefit analysis (CBA) into planning processes and decisions regarding needs for adapting to climate change and extreme weather. The Guidebook was published in 2020 and developed through the National Cooperative Highway Research Program, with input from practitioners at state departments of transportation (DOTs).

CalTrans Climate Change Vulnerability Assessment 2018 Summary Report - District 4

January 2018

The California Department of Transportation (CalTrans) vulnerability assessment of California’s District 4 (9 San Francisco Bay area counties) is a result of the 2013 CalTrans report on the department’s activities and plans to address and adapt the sector to climate change. The vulnerability assessment summary report describes the impacts of climate change on California’s Highway System in District 4, and a companion Technical Report describes the processes used to identify these impacts.

Post Hurricane Sandy Transportation Resilience Study in New York, New Jersey, and Connecticut

October 2017

The Federal Highway Administration led a Hurricane Sandy Resiliency Study to inform ways to improve resilience of the tri-state New York - New Jersey - Connecticut region's transportation system and to inform disaster recovery efforts. The study, which began in 2013 and was completed in late 2017, involved a detailed assessment of the impacts and disruption caused by Hurricane Sandy as well as from several other extreme weather events occurring in the area in 2011, and analyzed vulnerability and risk to the tri-state transportation system at three different scales: regional (entire study area), subarea (corridor/small network), and facility.

California State Route 37 Stewardship Study

February 2016

The University of California Davis Road Ecology Center undertook a stewardship study to assess the risk to California State Route 37 (SR 37) from sea-level rise.  SR 37 passes near San Francisco Bay, connecting Interstate 80 and Highway 101.  The road corridor and surrounding wetlands are threatened by sea-level rise and flooding. The road bed sits below sea level at its lowest elevation and is likely to experience erosion, flooding during storms, and inundation due to sea-level rise. The State Road 37 Stewardship Study (Study) included a stakeholder process and technical analyses to determine possible future solutions to reduce the vulnerability of the highway to climate impacts.

New York’s Expanded USGS StreamStats Tool

December 2015

The U. S. Geological Survey (USGS) has developed a web-based application that operates in conjunction with the existing StreamStats application for New York State to incorporate projected precipitation changes under various 21st century climate change scenarios. This application will allow transportation planners and engineers to explore how climate change may affect high flows, which can assist with the design of over-water infrastructure (such as culverts and bridges) to accommodate these changes.

Highways in the River Environment - Floodplains, Extreme Events, Risk, and Resilience - FHWA Hydraulic Engineering Circular 17 (HEC-17)

June 2016

The Federal Highway Administration (FHWA) manual Highways in the River Environment - Floodplains, Extreme Events, Risk, and Resilience provides technical guidance to assist transportation agencies in assessing vulnerabilities of assets and facilities to climate change and extreme events occurring in riverine environments. It includes new information on how to account for changing precipitation conditions including more frequent and extreme weather events that may affect transportation infrastructure and drainage systems in riverine environments, consisting of rivers and streams, lakes, wetlands, and other natural features conveying water.

U.S. Department of Transportation CMIP Climate Data Processing Tool

March 2016

The U. S. Department of Transportation's Coupled Model Intercomparison Project (CMIP) Climate Data Processing Tool provides readily available downscaled climate data in a format that is relevant and useful for transportation planners at a local level. The tool, which is in Excel format, processes raw climate model output to produce projections that are meaningful for transportation planners to consider design or operational changes needed to create transportation infrastructure and services that are more resilient to climate change impacts.

Florida Sea-level Rise Sketch Planning Tool for Transportation

October 2015

The University of Florida (UF) developed a geographic information system (GIS)-based “sketch planning tool” to help transportation planners in Florida identify transportation infrastructure potentially vulnerable to projected sea-level rise. The sketch planning tool offers a mapping function to visualize areas that will be affected by different sea-level rise scenarios based upon surface elevations and the location of infrastructure.   The tool is also customizable for experienced users to allow them to create more spatially refined inundation surfaces.
