Caltrans Activities to Address Climate Change - Reducing Greenhouse Gas Emissions and Adapting to Impacts

This report provides a comprehensive overview of activities undertaken by Caltrans statewide to reduce greenhouse gas emissions resulting from our operations and adapt the State's highway system to prepare for the impacts of climate change.

 

 

 

 

 

 

 

 

 

 

 

 

Addressing Climate Change Adaptation in Regional Transportation Plans: A Guide for California MPOs and RTPAs

The 2010 RTP Guidelines currently provides little direction for regions to analyze and address climate change adaptation. This effort will provide a clear methodology for regional agencies to address climate change impacts through adaptation of transportation infrastructure. The purpose of this manual is to expand knowledge and develop tools that will assist California MPOs and RTPAs with incorporating climate change impacts into planning, design, engineering, and operational decisions.

 

Guidance for Incorporating Sea Level Rise in the Project Initiation Document Process

The Caltrans Divisions of Environmental Analysis, Design and Transportation Planning have developed a guidance document for incorporating sea level rise into the project planning process. The documents include a technical guidance for the engineering design and a planning level document to determine what projects should consider sea level rise.

Both documents will be updated to include the sea level rise projections from the National Academies of Sciences study (above).

This guidance begins to incorporate sea level rise into the planning and design of projects vulnerable to the effects of sea level rise. The guidance provides sea level rise assumptions for the state along with criteria for determining when sea level rise should be incorporated into projects. [PDF]

 

Caltrans Climate Change Adaptation Hot Spot Map

The goal of this research project is to create a GIS-based assessment of transportation infrastructure vulnerabilities using available data and studies and to identify critical transportation hotspots (areas of increased vulnerability due to population, travel or climate effects). This research will also result in the development of a climate vulnerability plan that will assess the level and type of transportation infrastructure vulnerability, the adaptation options and strategies, and a framework for prioritizing implementation efforts.

National Academy of Sciences (NAS) Study of Sea-Level Rise by the National Research Council (NRC)

California Executive Order S-13-08 directed state agencies to plan for sea-level rise and coastal impacts, and it also requested the National Research Council (NRC) to establish a committee to assess sea-level rise to inform these state efforts. The states of Washington and Oregon, the U.S. Army Corps of Engineers, the National Oceanic and Atmospheric Administration, and the U.S. Geological Survey subsequently joined California in sponsoring this study to evaluate sea-level rise in the global oceans and along the coasts of California, Oregon, and Washington for 20130, 2050, and 2100.

East San Francisco Bay Sea Level Rise Vulnerability Study

Phase One

San Francisco Metropolitan Commission (MTC) conducted this project in partnership with the California Department of Transportation District 4 and the San Francisco Bay Conservation and Development Commission (BCDC). These three agencies constituted the Project Management Team.

The project was completed with support from the National Oceanic and Atmospheric Administration Coastal Services Center (CSC), the Association of Bay Area Governments (ABAG), the Bay Area Air Quality Management District (BAAQMD), and the Federal Highways Administration (FHWA).

Phase Two

The follow-up work (Phase Two) of this project will be conducted by the California Department of Transportation, District 4, using a grant from a FHWA with support from San Francisco Metropolitan Commission (MTC), San Francisco Bay Conservation & Development Commission (BCDC), and Bay Area Rapid Transit (BART).
