• 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.

Capitol Corridor (CA) Sea-Level Rise Vulnerability Assessment and 2014 Vision Plan Update

November 19, 2014

The Capitol Corridor Joint Powers Authority (CCJPA) conducted a sea-level rise vulnerability assessment for the corridor’s rail assets and is incorporating those findings into the agency’s Vision Plan, identifying sea-level rise as a critical issue in long-term planning and investments. The Capitol Corridor, which is managed but not owned by the CCJPA, serves as the primary public transportation connection between the Sacramento metropolitan area and the San Francisco Bay Area. Large stretches of the corridor run along waterfronts and through marshlands and other areas that will be increasingly vulnerable to inundation and flooding during storm events as sea levels rise.

Washington, DC Flood Levee System Improvements

December 2014

To prevent water from the Potomac and Anacostia rivers from flooding downtown Washington, D. C. , the U. S. Army Corps of Engineers (USACE) is improving the levee system along the north side of the National Mall, running from the Lincoln Memorial to the Washington Monument.   A levee system was originally erected to protect the District in 1939, following a major flood event in 1936.   This project will improve the levee system through a series of upgrades: a permanent closure at 23rd Street and Fort McNair, and the installation of a more robust removable wall, which will provide flood protection but also allow for traffic flow on 17th street between flood events.

Cape Cod Commission’s Adaptation Planning Activities for the Regional Transportation System

July 2015

The Cape Cod Commission (“Commission”) has begun to systematically consider the long-range impacts of climate change as it works to guide regional transportation- and development-planning efforts for an iconic but vulnerable area of coastal Massachusetts. The Commission is responsible for directing regional land-use policy, regulating developments whose impacts cross town boundaries, and supporting the 15 Cape Cod municipalities that make up Barnstable County with planning and technical expertise.

Plumb Beach Renourishment Project and Protection of Belt Parkway, Brooklyn, New York

2013

The Plumb Beach Renourishment Project involved the placement of sand on the beach to protect the Belt Parkway in Brooklyn, NY. The project, which is managed by the U. S. Army Corps of Engineers (Corps), is ongoing and is being implemented in two phases. In Phase I, the Corps nourished the beach with dredged sand and installed several geotube groins (sand bags) to prevent short-term erosion of the newly-deposited sand. Phase I was completed days before hurricane Sandy devastated the Northeast region.

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.
