2. Improve the resiliency and reliability of the transportation system and reduce or mitigate stormwater impacts of surface transportation § 450.216 — Development and content of the long-range statewide transportation plan This section requires the long-range statewide transportation plan to include by reference or by inclusion several planning or policy studies. The latest Federal legislation added emergency relief and disaster preparedness plans to the list of references plans. » Metropolitan Transportation Planning.

Recent Federal legislation includes the following two factors as part of the requirement: » Emphasize the preservation of the existing transportation system » Improve the resiliency and reliability of the transportation system and reduce or mitigate stormwater impacts of surface transportation § 450.316(b) — Interested parties, participation, and consultation In developing metropolitan transportation plans and TIPs, the MPO should consult with agencies and officials responsible for other planning activities within the Metropolitan Planning Area that are affected by transportation (including State and local planned growth, economic development, tourism, natural disaster risk reduction, environmental protection, airport operations, or freight movements) or coordinate its planning process (to the maximum extent practicable) with such planning activities. § 450.324(f)(7) — Development and content of the metropolitan transportation plan This section requires metropolitan transportation plans to include consideration of a range of concerns and issues. Recent Federal legislation added actions to reduce the vulnerability of the existing transportation infrastructure to natural disasters to this list. » 2013-2015 Climate Resilience Pilot Program: Outcomes, Lessons Learned, and Recommendations. Report FHWA-HEP-16-079. 2016. Accessed August 27, 2020 from: https://www.fhwa.dot.gov/environment/sustainability/resilience/pilots/ Results from pilot studies on incorporating resilience concepts into transportation decision-making processes include the following examples: Hillsborough MPO, Florida: https://web.archive.org/web/20170113175350/ http://www.fhwa.dot.gov/environment/sustainability/ resilie nce/pilots/2013-2015_pilots/florida/final_report/index.cfm Interesting and important consideration of risks associated with sea level risk, storm surge, and inland flooding. The Plan developed a prioritized list of highly vulnerable locations on the transportation system.
