TDOT, in conjunction with the MPOs throughout the state, will conduct a systematic evaluation of the vulnerability of the State's multimodal infrastructure. They will consider both existing and planned transportation assets.
MDOT will conduct a vulnerability assessment to identify at risk assets, identify a method for incorporating risk information into their asset management systems, and identify maintenance and operational activities needed to address climate change risk.
CAMPO, the Austin area MPO, will use FHWA's framework to conduct a vulnerability assessment of transportation infrastructure in their region. They will consider temperatures and extreme heat, extreme precipitation and flooding, drought, and wildfire. At the conclusion of the study they will conduct a regional symposium to share the report findings broadly.
NCTCOG will conduct a vulnerability and risk assessment for critical roadway and rail facilities in the Dallas-Fort Worth region. The region is subject to extreme heat and drought followed by flash flooding events. Near the beginning of their study, NCTCOG will hold a meeting for partners and/or other interested parties to finalize a list of infrastructure to include in the assessment and to determine whether to focus on both drought and flooding or just one type of weather event.
The Maine DOT will assess the vulnerability of state-owned transportation infrastructure to extreme precipitation events and projected sea level rise in six coastal Maine communities. This project will dovetail with a Project of Special Merit (PSM) recently funded by NOAA entitled "Integrating Science into Policy: Adaptation Strategies for Marsh Migration," thus providing the transportation infrastructure component of interest to municipalities as well as Maine DOT's asset management and maintenance programs.
ADOT will assess the vulnerability of state-owned transportation infrastructure, based on findings from their recently completed study: Preliminary Study of Climate Adaptation for the Statewide Transportation System in Arizona. ADOT will focus on a transportation corridor connecting Nogales, Tucson, Phoenix and Flagstaff as a case study. ADOT will analyze impacts of extreme surface temperatures, floods, dust storms, and species migration on pavement, drainage, bridges, and roadside vegetation/stabilization/habitat.
ADOT&PF and the Alaska FLMAs (BLM, FWS, NPS, and USFS) will identify transportation assets that are adversely affected by climate change, identify engineering and other strategies to make infrastructure more resilient and adaptable, and identify priority-based work plans for addressing the most vulnerable assets first.
ConnDOT will conduct a systems-level vulnerability assessment of bridge and culvert structures six to twenty feet in length from inland flooding associated with extreme rainfall events. The assessment will evaluate the existing storm-event design standards, the recent (ten year) historic actual rainfall intensity and frequency, and evaluate the hydraulic capacity of these structures using the projected increases in rainfall. The study area is in the northwest portion of the state.
MassDOT focus on the Central Artery system in Boston. They will work with UMass and others to conduct detailed flood impact assessment for the project area with ADCIRC modeling, using this information to identify where and how the Central Artery is vulnerable to flooding. They will then investigate adaptation options including a cost-benefit analysis based on both current and future conditions in order to determine when various options become costs-effective.
MNDOT will conduct a systems-level vulnerability assessment to flash flooding events in two districts to better understand the type, location, and reason for asset risks from flash floods. They will then conduct a focused adaptation analysis of specific high-risk facilities identified in the system assessment.
This study will look at the New York portion of the Lake Champlain Basin in northern New York. Working with the Nature Conservancy, which recently predicted climate change impacts to the basin through 2100, NYSDOT will: identify and prioritize culverts and road segments that are most vulnerable to changing precipitation; develop engineering-based design options; create an economic tool to evaluate the full benefits and cots of adaptation options (including costs to non-DOT entities); and incorporate climate vulnerability assessments into existing NYSDOT standards, guidelines, and tools.
MTC will build on their previous FHWA pilot, looking more in depth at three focus areas within the study area to develop multimodal adaptation options and an implementation strategy.
This effort focuses on Palm Beach, Broward, Miami-Dade, and Monroe Counties in South Florida. The project will include some vulnerability assessment work, but it is mainly focused on developing a consistent methodology and decisions support and screening tool for incorporating climate change impacts into transportation decision making.
ODOT will develop a corridor level Coastal Hazards Adaptation Implementation Plan for Highway 101 in the northwest area of the state. ODOT will develop a set of effective adaptation measures to reduce risk and improve the resilience of transportation assets vulnerable to climate change and extreme weather, conducting an engineering and technical review for building adaptive capacity. The project has a focus on landslide risk and flood warning.
Caltrans will develop a range of adaptation strategies at four specific locations on the state highway system in the northwest corner of the state (District 1). They will determine vulnerability of these segments due to sea level rise, coastal bluff erosion, high precipitation, and the resulting flooding. They will work with regional transportation partners, several Native American Tribal Governments, federal agencies, and a university.
Hillsborough MPO, of the Tampa area, will identify potential adaptation/mitigation projects in the MPO's 2040 Plan to improve resiliency of key transportation facilities. They hope to incorporate results into Florida DOT's EDTM.
This study builds on WSDOT's earlier pilot to examine adaptation options in an identified highly vulnerable area, the Skagit River Basin, which includes I-5. The U.S. Army Corps of Engineers is preparing a DEIS for a Skagit River General Investigation Study, and the WSDOT study would feed into that effort. Outcomes of WSDOT's study would include:
IDOT will assess the vulnerability of highway structures in Iowa due to climate change impacts on extreme weather events. The project will monitor, predict, assess and provide alerts when vulnerable highway infrastructure assets are at risk from extreme rainfall events.
SHA will conduct, in partnership with appropriate agencies and jurisdictions, an assessment of asset resilience to climate change effects and extreme weather. SHA will focus on the Eastern Shore before broader analysis of the entire state is completed. SHA will identify the types of drainage asset issues being seen now and evaluate how to address them now and in the future. SHA will consider adaptation options and best management practices, standards, or other ways to support the adoption of adaptive design.
