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.

Cost-Benefit Model Evaluation – Mud Bay Bridge, Puget Sound, Washington

2013

The Washington State Department of Transportation (WSDOT) tested a National Cooperative Highway Research Program (NCHRP) cost-benefit model by evaluating adaptation options for replacing Mud Bay Bridge on SR101 in Olympia. The bridge serves the community as a major corridor through Olympia and provides access to Interstate-5, the main north-south freeway in Puget Sound. Depending on the rate of sea-level rise in the region under various climate change scenarios, it is anticipated that Mud Bay Bridge will become inundated before 2100.

New Orleans Evacuspots and Evacuteers Program

2013

The New Orleans non-profit Evacuteer. org installed clearly recognizable public art in “Evacuspots,” New Orleans’ designated emergency evacuation locations, to facilitate public transportation during a mandatory evacuation in advance of a Category three or higher hurricane. Evacuteer. org partners with the New Orleans Office of Homeland Security and Emergency Preparedness to aid in the operation of City Assisted Evacuation (CAE), the city’s free, public evacuation program to assist residents without their own means of transportation.

Necanicum River - Highway 101 Flood Mitigation

2013

A flood mitigation and habitat restoration project led by the North Coast Land Conservancy (NCLC) and funded by the Oregon Department of Transportation (ODOT) removed a levee built in the 1960s and reestablished the Necanicum River floodplain, mitigating flooding of Highway 101.

Caltrans Devil’s Slide Realignment Project

2013

The California Department of Transportation (Caltrans) invested in an expensive relocation of the Devil’s Slide segment of Highway 1, a coastal highway linking Half Moon Bay and San Francisco in San Mateo County. The segment was repeatedly closed due to damage from rockslides and erosion. The state decided to relocate the road at additional up-front expense (approximately $342 million) to avoid the long-term maintenance costs of rebuilding the road repeatedly in its existing location. Although not specifically implemented in response to climate change, this project provides an example of how realignment may present a cost effective strategy for adapting transportation assets in the face of mounting maintenance costs from repeated damage due to climate-related events.

Port Authority of New York and New Jersey - PATH System Resiliency and Recovery Improvements

In the wake of Hurricane Sandy and the substantial damage done to the infrastructure managed by the Port Authority of New York and New Jersey (PANYNJ), PANYNJ has been repairing and rebuilding infrastructure components to make its PATH transit system more resilient to future Sandy-like storm events. The PATH system, the heavy rail (6 to 12-car trains) rapid transit system linking Manhattan to New Jersey cities and suburban communities, experienced the most severe flooding of any PANYNJ facilities during Hurricane Sandy.

Elevating Electrical Substations for Port Authority of New York and New Jersey

The Port Authority of New York and New Jersey (PANYNJ) has implemented projects to elevate electrical substations relied upon by critical transit systems – the Port Authority Trans-Hudson (PATH) and LaGuardia Airport in New York City – in order to better protect them from flooding during storm events.  PANYNJ is in the process of elevating two Substations for the PATH system that were damaged during Sandy and elevating and replacing an outdated substation at LaGuardia Airport.

Boston Complete Streets: Design Guidelines

2013

The Boston Transportation Department and other Boston city agencies have developed Complete Streets guidelines that incorporate green infrastructure components such as permeable pavements and street trees to address impacts of climate change including increased heat and precipitation. “Complete streets” are designed to create more sustainable transportation networks by encouraging multi-modal travel options and enhancing the natural environment within the public right-of-way.  By promoting the use of green infrastructure, the City can help reduce the urban heat island effect and mitigate flooding.

Redesign of 21st Street, Paso Robles, California

2013

The City of Paso Robles, California redesigned a downtown street utilizing complete and green street design principles to better manage precipitation and stormwater runoff in a natural drainage area.   The 21st Street redesign project has proven successful as a means of stormwater management.   In a three-month period, the street’s new features, which include pervious pavement, street trees, and a stream channel in the middle of the street, helped mitigate flooding from nine significant rain events, and recharged approximately 250,000 gallons of stormwater into the region’s groundwater basin.

Federal Transit Administration (FTA) Emergency Relief Program: Sandy Disaster Aid Resilience Projects

2013

In the aftermath of Hurricane Sandy, the Federal Transit Administration (FTA) allocated $4. 3 billion of its disaster recovery money specifically for projects in the Sandy-impacted areas that increase the resilience of public transportation systems and facilities to future disasters and the impacts of climate change. Funding for resilience projects was allocated in separate tiers. First, for “locally-prioritized projects,” which include resilience improvements made in conjunction with other recovery and rebuilding projects or lower cost stand-alone projects that could be implemented quickly.

Transportation Research Board (TRB) NCHRP: A Pre-Event Recovery Planning Guide for Transportation

2013

The Transportation Research Board (TRB) of the National Academies National Cooperative Highway Research Program (NCHRP) developed Report 753: A Pre-Event Recovery Planning Guide for Transportation, which provides an overview of steps involved in planning and preparing for the recovery of critical transportation infrastructure after a catastrophic event such as a severe storm or wildfire. The Guide was developed to assist transportation owners, operators and planners with pre-event recovery planning.
