• Transportation Resources

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.

Federal Triangle Stormwater Drainage Study

October 2011

The Federal Triangle Stormwater Drainage study analyzed the causes of a 2006 flood event that put the Federal Triangle Area of Washington D. C. under up to 3 feet of water, including several major traffic arteries, tunnels, and subway stations. The Study analyzes possible alternatives to reducing the risk of interior drainage flooding, including permeable pavements and other Low Impact Development (LID) techniques. In considering the causes of flooding in the area, the Study uses the 200-year flood as a proxy for assessing how climate change may increase flood risks and the frequency of severe storm events.

Washington State DOT (WSDOT) Guidance for Project-Level Climate Change Evaluation

January 2017 Update

The Washington State DOT (WSDOT) issued this guidance to assist the agency’s project planners in considering climate change impacts, which is required for all WSDOT projects subject to the National Environmental Policy Act (NEPA) and Washington’s State Environmental Policy Act (SEPA). In addition to obligations under NEPA and SEPA, WSDOT’s 2011-2017 Strategic Plan directs the agency to evaluate future climate-related risks and identify strategies to reduce risk. The guidance provides a standard process for analysis and template language to enable planning-level consideration of Washington’s projected climate impacts.

NPS Gulf Islands National Seashore - Fort Pickens Ferry System

September 2015

In order to maintain cost-effective, sustainable visitor access to the Gulf Islands National Seashore (GUIS), the National Park Service (NPS) proposed the development of passenger ferry service from Pensacola, Florida, to Fort Pickens. Santa Rosa Island, the site of Fort Pickens and part of GUIS, is susceptible to coastal storms and erosion. The Fort Pickens Road within GUIS is frequently damaged by storms, including hurricanes in 2004 and 2005. The transportation system in the Fort Pickens area is particularly vulnerable to disruptions caused by these impacts.

California Climate Action Team Sea-Level Rise Guidance Document – for use by Caltrans and other State Agencies

March 2013

The State of California Sea-Level Rise Guidance Document was developed by the Coastal and Ocean Working Group of the California Climate Action Team (CO-CAT) to provide guidance for incorporating sea-level rise (SLR) projections into planning and decision-making in California. The guidance provides ranges of SLR for all California agencies, including the Department of Transportation (CalTrans), to be used for risk-based scenario planning and assessments, such as long term transportation planning and vulnerability assessments.

Confusion Hill Bypass in Mendocino County, California

2009

The California Department of Transportation (Caltrans) completed the Confusion Hill Bypass project to reduce the vulnerability of Highway 101 in Northern California to landslides. Between 1996 and 2003, Caltrans spent a total of $14 million repairing and maintaining a 2-mile stretch of the highway. In the winter of 2002/2003, Highway 101 was closed 10 times due to landslides. Caltrans identified landslides and flooding as constant challenges in Caltrans District 1, which includes Confusion Hill in Mendocino County.
