Transportation Sector Case Studies

These resources include case studies of adaptation in the transportation sector, developed by the Georgetown Climate Center as part of a cooperative agreement with the Federal Highway Administration. The case studies include examples of how adaptation has been incorporated into decisionmaking at all stages of the transportation lifecycle: assessing vulnerability, planning, design, and operations and maintenance.

Resources are automatically presented by rating, but can also be sorted by date and title. Apply additional filters to narrow the list by climate impact, region, transportation mode or stage of decision-making, state, or jurisdictional focus.

North Carolina Highway 12 Storm Recovery

The North Carolina Department of Transportation (NCDOT) is implementing several different solutions to address frequent overwashes, erosion, and more severe damage to North Carolina Highway 12 (NC 12) following Hurricanes Irene and Sandy. These measures, intended to improve the future resilience of the highway, include bridge construction and temporary beach nourishment.

Norwegian Public Roads Administration's Climate and Transport R&D Project

May 2013

Beginning in 2007, the Norwegian Public Roads Administration (NPRA) conducted a major research and development project to evaluate the impacts of climate change on Norwegian roads and recommend adaptation measures to be incorporated into road design, construction, operation, and maintenance and help ensure safety and accessibility of roads in a changing climate. The project, entitled “Climate and Transport,” has resulted in revised guidelines and specifications, to better plan and design for increasing risk related to flooding and sea-level rise.

Oregon Dept. of Transportation Climate Change Adaptation Strategy Report

April 2012

The Oregon Department of Transportation’s (ODOT) Climate Change Adaptation Strategy Report is intended to provide a preliminary assessment of likely climate change impacts on ODOT assets and operations and adaptation strategies. ODOT is responsible for more than 19,000 lane miles of state highway, 2,700 bridges, thousands of culverts, and other critical infrastructure. All of this infrastructure is potentially vulnerable to the impacts of climate change, such as increased incidence of landslides, flooding, coastal erosion, and wildfires.

Oregon Guidance on Biofilters for Storm Water Discharge Pollution Removal

January 2003

In 2003, the Oregon Department of Environmental Quality (DEQ) published guidance on the use of “biofilters” to remove pollution from stormwater. Biofilters include a variety of green infrastructure techniques installed along roadways to filter pollution from stormwater runoff such as constructed wetlands and bioswales (vegetated swales or ditches), among others. The guidance details the design best management practices (BMPs) that have been proven to work well in constructing biofilters, and argues that biofilters may be the “most economical” way to remove sediment and other pollutants from runoff.

Oyster River (New Hampshire) Culvert Analysis Project

March 2010

In this project the Piscataqua Region Estuaries Partnership (PREP) performed a vulnerability assessment of the hydrology and drainage system of the Oyster River watershed in southeastern New Hampshire and its capacity to adapt to climate change impacts and increased development. The project used a geographic information system (GIS) based watershed model to identify the road/stream crossing culverts that are vulnerable to failure due to extreme storms with increased precipitation, in combination with development of the watershed.

PANYNJ Assessment of the Vulnerability to the Impacts of Climate Change

April 2011

The Port Authority of New York and New Jersey (PANYNJ) conducted a vulnerability and risk assessment of the agency’s critical infrastructure to the anticipated effects of climate change, including sea-level rise and increased storm surge, precipitation, and temperatures.   PANYNJ analyzed climate-related vulnerability and level of risk for a wide variety of agency infrastructure, including airports, marine terminals, tunnels and bridges, rails, bus stations, and other facilities.   The risk analysis was used to prioritize the highest risk assets and develop adaptation strategies for those assets.

Paths to a Sustainable Region - Boston Region Long-Range Transportation Plan

September 22, 2011

The Boston Region Metropolitan Planning Organization’s (MPO) Long Range Transportation Plan (LRTP), “Paths to a Sustainable Region,” outlines policies, programs, and projects of regional significance or major infrastructure projects that have been identified as priorities for the region between now and 2035. The Boston LRTP adds climate change as an area of emphasis, and acknowledges the importance of adaptation measures to lessen or avoid potential impacts from climate change.

Pennsylvania Climate Adaptation Planning Report – Infrastructure Chapter

March 2010

The Pennsylvania Climate Adaptation Planning Report presents climate adaptation recommendations and strategies developed by stakeholder working groups from key sectors, including the infrastructure sector with a focus on transportation. The Infrastructure working group identified the key focus areas, vulnerabilities and risks to infrastructure assets; and prioritized actions (high, medium or low) based upon specific criteria including cost, timeliness of implementation, political support, data availability, planning, risk level, co-benefits, and risks to public health and safety.

Piedras Blancas Highway 1 Realignment - Caltrans/San Luis Obispo

2015

The California Department of Transportation (Caltrans) is planning to realign a 2. 8 mile section of iconic Highway 1 to address current and anticipated impacts from coastal erosion and storm surge.  This section of Highway 1, which is north of the Piedras Blancas Lighthouse in San Luis Obispo County, is already experiencing increased storm damage from flooding and erosion, and these impacts are projected to increase with rising sea levels and higher storm surge caused by climate change.  Realigning the highway away from the coast will reduce its vulnerability to current damage as well as to future climate impacts and will protect the highway from bluff retreat for the next 100 years.

Pilsen Sustainable Streets (Chicago, Illinois Department of Transporation)

October 9, 2012

On October 9, 2012, the Chicago Department of Transportation (CDOT) completed the first phase of the Pilsen Sustainable Streets project, which uses permeable pavement and green infrastructure elements to address current and projected increases in temperature and precipitation. The sustainability project, described as the “greenest street in America,” consists of a two-mile stretch of Blue Island Avenue and Cermak Road located in the Pilsen neighborhood. The project features will help reduce flooding, manage stormwater, and reduce temperatures, allowing CDOT to address two potential climate impacts with the same project.
