The process has been institutionalized in the agency’s decision-making processes. Massachusetts DOT: https://web.archive.org/web/20170113175350/http://www.fhwa.dot.gov/environment/sustainability/resilie nce/pilots/2013-2015_pilots/massdot/index.cfm Systematic examination of sea level rise and storm surge impacts on coastal Massachusetts with special emphasis on downtown Boston and impacts on depressed freeway. Minnesota DOT: https://web.archive.org/web/20170113175350/http://www.fhwa.dot.gov/environment/sustainability/resilie nce/pilots/2013-2015_pilots/minnesota/final_report/index.cfm Innovative use of risk factors and a systematic process for identifying the vulnerability of state DOT assets to inland flooding. Focus was on two DOT districts. The approach used the latest methods for predicting future flood levels. South Florida: https://web.archive.org/web/20170113175350/http://www.fhwa.dot.gov/environment/sustainability/resilie nce/pilots/2013-2015_pilots/south_florida/final_report/index.cfm Three MPOs and one county study on potential impacts of sea level rise and storm surge on state highway and fixed rail assets. Plan development was based on then state-of-practice methods for identifying vulnerable assets. Plan also recommended changes to planning and decision-making processes. » 2017-2019 Pilot Program: Asset Management, ExtremeWeather, and Proxy Indicators. Accessed September 14, 2020 from: https://www.fhwa.dot.gov/asset/pilot/ The purpose of this pilot program was to develop information on how asset management practice could be better linked to extreme weather stresses and incorporated into asset decisionmaking. Six states participated in the pilot study and prepared reports on their results: Arizona, Kentucky, Maryland, Massachusetts, New Jersey, and Texas. A description of each pilot study and a list of asset management- related resources can be found at: https://www.fhwa.dot.gov/asset/resources/pilot.pdf » 2016-2017 Pilot Program: Nature-based Resilience for Coastal Highways. Accessed September 14, 2020 from: https://www.fhwa.dot.gov/environment/sustainability/resilience/ongoing_and_current_research/green_in frastructure/ Five states and the U.S. Army Corps of Engineers participated in a pilot program to examine the potential for natural infrastructure to protect coastal roads and bridges: Delaware, Maine/New Hampshire (in one pilot), Mississippi, and Oregon. The pilots ranged from assessing different types of vegetated berms to developing conceptual designs for protecting coastal roads. » Transportation Engineering Approaches to Climate Resiliency (TEACR) Study . 2016.
