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.

Charlotte County-Punta Gorda 2035 Long Range Transportation Plan

December 2010

The Charlotte County – Punta Gorda Metropolitan Planning Organization’s (MPO) Long Range Transportation Plan contains a section on hazard mitigation designed to help the MPO identify specific roadways and properties within the region that are at risk of sea-level rise and storm surges, and identify strategies that can help protect the region from these climate-change-induced hazards. Chapter 13 profiles natural and man-made hazards that are common in the MPO area; presents estimates of the level of exposure and vulnerability of various components of the transportation system; describes a scenario-based planning exercise to integrate hazard mitigation into collaborative land-use and transportation planning; identifies various mitigation strategies to reduce the vulnerability of the transportation system; and suggests and incorporates a new set of goals and objectives into the LRTP.

Surfer’s Point Managed Retreat Project – Relocation of Transportation Facilities

The Surfer’s Point Managed Shoreline Retreat Project involved the relocation of a bike path and parking lot along 1,800 feet of shoreline in City of San Buenaventura, Ventura County. The transportation assets affected by the project include a damaged bike path, a 223-space parking lot for the Ventura County Fairgrounds, and Shoreline Drive.  Surfer’s Point is a beach and popular surf break at mouth of the Ventura River.

Edmonston, Maryland Green Streets Project

2010

Edmonston, a small town near Washington DC in Prince George’s County, MD, created a “green street” to address previous problems with flooding on Decatur Street near the Anacostia River. The town wanted to better manage that flooding and improve water quality, as well as to manage traffic by narrowing the street.   The project utilizes a variety of green infrastructure tools to reduce stormwater runoff, thereby decreasing the amount of polluted water that enters the Anacostia River.   While the project does not specifically reference climate change as a motivation, the methodology and considerations for this project, could be useful for a jurisdiction that will experience heavier precipitation due to climate change.

San Diego Association of Governments Climate Action Strategy – Transportation Goal

March 2010

The San Diego Association of Governments (SANDAG) 2010 Climate Action Strategy, intended to guide regional and local policymakers in addressing climate change and preparing for its effects, includes among its goals to “protect transportation infrastructure from climate change impacts. ” The Strategy identifies the climate change impacts most likely to affect the San Diego area, including extreme heat, greater risk of mudslides after wildfires, and sea-level rise and storm surge, and lists policy measures that SANDAG and local governments can take to address them.

Winslow Way Street Redesign (Bainbridge Island, WA)

2011

The City of Bainbridge Island redesigned its main downtown street to update aging water infrastructure, improve walkability and multimodal uses, and better manage stormwater using more natural and vegetated solutions. The new design is more walkable and accessible, supports biking, better manages stormwater with green infrastructure practices, and encourages social cohesion through smart design. Over half a mile in length, this innovative redesign protects street trees and incorporates stormwater planters, rain gardens, and other methods to retain stormwater and prevent flooding.

Greenworks Philadelphia Plan - Transportation Recommendations

2009

Greenworks Philadelphia is a comprehensive six-year plan (“Plan”) that sets goals for “greening” the City of Philadelphia – increasing the city’s energy efficiency, reducing greenhouse gas emissions, improving the environmental quality of the city, and adapting to the dangers posed by climate change. This case study focuses only on the transportation-related recommendations included in the Plan – increasing the percentage of city assets in a “state of good repair” and using green infrastructure strategies to improve stormwater management and reduce flood impacts to transportation infrastructure.

Chicago Green Alley Handbook

2010

The Chicago Department of Transportation (CDOT) authored the Green Alley Handbook to encourage the use of best management practices (BMPs) in and around Chicago alleyways and to address impacts to the city’s infrastructure likely to result from projected increases in precipitation and temperature. The handbook promotes sustainable alley design and adjacent landscaping practices to help reduce flooding and manage stormwater, reduce urban heat, promote recycling, and conserve energy.

Rainscaping Iowa - Permeable Pavement Projects

2010

Rainscaping Iowa, an educational campaign that promotes urban stormwater management practices, encourages the use of permeable pavement by featuring successful installations in the state. By gathering feedback on previous projects, Rainscaping Iowa simultaneously highlights the environmental benefits of permeable surfaces and provides lessons for future installations and maintenance. Importantly, the campaign’s literature describes how permeable paving surfaces can help reduce runoff and improve water quality in the face of changing precipitation and increasing heavy rainfall events.

California Department of Transportation (Caltrans) – Green Technologies for Reducing Slope Erosion

January 28, 2010

The California Department of Transportation (Caltrans) Division of Research and Innovation conducted a Preliminary Investigation (PI) to identify strategies for reducing roadside slope erosion and preventing costly slope failures as climate change alters patterns of precipitation in California. The PI found that in general, California is a leader in erosion control and stormwater management, but recommended follow-up research on the effectiveness of specific plants or “green” products that may enhance or improve the nature-based methods for stabilizing slopes that California has already begun to implement.

City of Toronto (Ontario, Canada) Climate Change Risk Assessment Tool

2010

The City of Toronto developed its Climate Change Risk Assessment Tool, a software program and review process, to enable Toronto’s service and infrastructure providers to identify climate change risks and assess potential actions to reduce the impacts of climate change on infrastructure. Toronto’s Transportation Services Division (TSD) tested the tool in a 2011 pilot study, examining the impacts on 90 assets and services from seven extreme weather event types over two time horizons. The TSD pilot found that the frequency and intensity of extreme weather events is expected to quadruple the number of extreme risk scenarios by 2050.
