Addressing Climate Change Adaptation in Regional Transportation PlansA Guide for California MPOs and RTPAsareas consider various sea-level rise scenarios for the years 2050 and 2100. Thisprovides guidance specific to California as well.The 2010 CTC RTP Guidelines provide only general guidance on climateadaptation in Section 6.30 Adaptation of the Regional Transportation System toClimate Change. Specifically, the document suggests the following best practices:Notwithstanding a lack of reliable information on the future impacts ofsea-level rise, precipitation changes, or extreme heat events, MPOs andRTPAs should begin to address climate change in their long-rangetransportation plans. There are numerous ways planning agencies canbegin preparing for climate change adaptation on the transportationinfrastructure including preliminary mapping of infrastructure that isvulnerable to changes in precipitation, heat, and sea-level rise. It is alsorecommended that design and planning standards be re-evaluated toaccommodate potential changes. It is important to ensure that plannedinfrastructure is engineered and built in locations that can withstandfuture climate change impacts (CTC 2010).Because climate information, projections and the science are constantly evolving,it is important to incorporate the most up-to-date guidance available before theplanning process, and to stay up-to-datewith new information available.Developing Stakeholders in a Preliminary ClimateStudyIn the Arizona DOT’s Preliminary Study of ClimateAdaptation for the Statewide Transportation System inArizona (2012), the project team used a “knowledgemapping” approach to determine the process flow ofthe planning, project development, and assetmanagement activities within the agency. To achievethis, the project team reviewed agency organizationalcharts, and identified departments that could playimportant roles in addressing climate adaptation,including management staff, technical staff, and“cross‐cutting” departments, who would work acrossdisciplines to provide data to either the managementor technical staff. The project team then consideredthe potential climate impacts that could affect ArizonaDOT’s operations, and assigned roles related to theseimpacts to the departments identified through theorganizational chart exercise. After that, focus groupswere conducted with members of these identifieddepartments to clarify their roles, collect feedback, anddetermine if the “knowledge mapping” exercise” wasthorough and accurate.Source: ADOT (2012).Identify and CultivateStakeholdersCreate Stakeholder Knowledge MapBecause climate change adaptation is aninterdisciplinary responsibility, manyindividuals and departments within theMPO/RTPA and externally will beidentified for carrying out plans, riskassessments and adaptation actions.At the beginning of the RTP process, thelead coordinator should identifystakeholders both inside of theMPO/RTPA, as well as at the cities,counties, and at Caltrans, who might beinvolved in performing the planningassessment, engaging with operational ordesign practices, or providing monitoringand feedback in response to climateimpacts. Generally, there are threecategories of stakeholders who should beinvolved.8-4 Cambridge Systematics, Inc.
Addressing Climate Change Adaptation in Regional Transportation PlansA Guide for California MPOs and RTPAs Management/Board of the RTP Process. This includes individualssupporting the overall effort to include climate adaptation within the RTP,providing opportunities for cross-agency planning for a potential change inpractice or new opportunity to integrate climate adaptation into the planningand implementation processes.Technical Staff at the MPO/RTPA. This includes individuals who havedirect planning, operations or design responsibilities that would considerclimate adaptation in their practices. These individuals would have a directrole in preparing for or responding to climate impacts.Cross-Cutting Agencies. Individuals in these departments would likelywork across disciplines providing data or input to management and technicalstaff. There is a wide variety of expertise that could be included in thiscategory, including individuals in emergency response and natural hazardsplanning, economic development, public works engineering, regional entitiesincluding air districts and county agencies, regional science organizations oruniversities and local nongovernmental organizations.MPOs/RTPAs have an expansive role that spans planning, design andoperations functions. It is appropriate to coordinate with city agencies, publicworks, or state agencies to determine a transportation asset or facility’s resiliencyand develop relevant adaptation options.Set Up Advisory BoardThe MPO/RTPA would ideally select candidates from the stakeholders listed inthe previous section to set up an advisory board. This board can convene inmultiple ways depending on the regional make-up, including as a task force, acommittee, or a series of expert workshops. Depending on the level of effortpursued, the duration of the policy development period, and the availability ofstaff, an advisory board can be used for a quick sketch-level assessment or toformulate a longer term strategy or assessment process incorporated into theformal RTP. It is very likely that this board would comprise many stakeholdersfrom outside the MPO/RTPA as it will be important to account for local andregional activities from different sectors as well as at different geographic scales.In addition to determining potential impacts to transportation infrastructure inthe region, a critical task of the advisory board will be assessing how wellexisting policies and programs respond to projected climate changes.Survey Existing Climate Adaptation EffortsReview Hazard Mitigation PlansAlthough very few MPOs/RTPAs have ventured into climate vulnerability andrisk assessment, many work with their counties to develop hazard mitigationplans and conduct local hazard mitigation activities. Using existing hazard planscan offer lessons for adaptation strategy development: natural hazard impactsCambridge Systematics, Inc. 8-5
