Addressing Climate Change Adaptation in Regional Transportation PlansA Guide for California MPOs and RTPAs1.3 DATA SOURCES AND STATE-LEVEL GUIDANCEAlthough there is currently no requirement at the federal or state level forincluding climate adaptation into the regional transportation planning process,the consideration of climate change is important in practicing good planning.This document refers to three levels of documentation that are used as datasources endorsed by the State of California and best practices information.Federal Highways Administration (FHWA) and Federal-Level Guidance.In general, activities to plan, design, and construct highways to adapt tocurrent and future climate change and extreme weather events are eligible forreimbursement under the federal-aid program and for funding under theFederal Lands program. However, program funds are limited and their usefor adaptation purposes should be considered as a cost-effective means toextend and preserve the useful life of federal-aid and Federal Lands highwayfacilities. This section provides high-level summary documentation thatMPOs and RTPAs should be aware of at the federal level.Caltrans and State-Level Guidance. The State of California addressesadaptation to climate change through its California Climate AdaptationStrategy and Adaptation Planning Guide (APG). The APG provides adecision-making framework intended for use by local and regionalstakeholders to aid in the interpretation of climate science and to develop asystematic approach to reducing risks caused, or exacerbated, by climatechange. The State’s third major assessment on climate change explores localand statewide vulnerabilities to climate change, highlighting opportunitiesfor taking concrete actions to reduce climate-change impacts. Backgrounddata and the latest information can be found on the Climate Change portal:http://www.climatechange.ca.gov/adaptation/.The Cal-Adapt On-line Tool. The California Natural Resources Agency andthe California Energy Commission have released Cal-Adapt, a web-basedtool which enables city and county planners, government agencies, and thepublic to identify potential climate change risks in specific areas throughoutCalifornia. At the time of writing, this is the pre-eminent statewide tool forclimate analysis in California.Details for the key documents referenced can be found in Table 1.1.1-4 Cambridge Systematics, Inc.

Adaptationinvolves adjusting the way the transportation community plans, designs, constructs, operates andmaintains transportation infrastructure to address the impacts of climate change and extreme weatherevents. This document provides important information for any project pursuing adaptation strategies.This guidance is intended for use by Caltrans Planning staff and Project Development Teams todetermine whether and how to incorporate sea-level rise concerns into the programming and design ofCaltrans projects. Because of the evolving nature of climate change science and modeling, this guidanceis subject to revision as additional information becomes available. Although MPO and RTPA planners willnot likely need to refer to these documents in the planning process, they will need to consider them at theproject level.The guidelines reflect recent revisions to address the planning requirements of Senate Bill (SB) 375 (SB375, Steinberg, Statutes of 2008) and other planning practices. SB 375 targets regional greenhouse gasemission reductions from passenger vehicles and light duty trucks through changes in land use andtransportation development patterns. To achieve these changes, the law encourages MPOs to thinkdifferently about how communities are designed. As a result, MPOs in partnership with local governmentsare now required to develop a sustainable communities strategy as part of the transportation planningprocess for inclusion in the RTP. The 2010 CTC RTP Guidelines provide only general guidance onclimate adaptation in Section 6.30 Adaptation of the Regional Transportation System to Climate Change.This guidance provides an overview of current climate projections for increased temperature and extremeheat conditions for California, describes the health effects of extreme heat, and presentsrecommendations for state and local planners, local governments, emergency response, and public healthand health care professionals and institutions.The APG consists of the Planning Guide overview document and three companion documents for use invarious combinations on an as-needed basis. In Planning for Adaptive Communities, the basis for climatechange adaptation planning is presented. The document introduces a step-by-step process for local andregional climate vulnerability assessment and adaptation strategy development. Three companion pieces:Defining Local and Regional Impacts, Understanding Regional Characteristics and Identifying AdaptationStrategies give more in-depth understanding of how climate change can affect a community, how theimpact of climate change varies across the State and explores potential adaptation strategies thatFHWACaltrans9/24/2012 FHWAandCaltransGuidance5/16/2011 FHWAandCaltransGuidanceCTC 4/7/2010 FHWAandCaltransGuidanceCEC8/31/2012 State-LevelGuidanceCNRA 7/2012 State-LevelGuidanceCambridge Systematics, Inc. 1-5
