(1)The department shall develop a resilience action plan for the State Highway System based on current conditions and forecasted future events. The goals of the action plan must be to:
(a)Recommend strategies to enhance infrastructure and the operational resilience of the State Highway System that may be incorporated into the transportation asset management plan.
(b)Recommend design changes to retrofit existing state highway facilities and to construct new state highway facilities.
(c)Enhance partnerships to address multijurisdictional resilience needs.
(2)The resilience action plan must include all of the following:
(a)An assessment of the State Highway System to identify roadway facilities and drainage outfalls that may be subject to vulnerabilities associated with tidal, rainfall

(1) The department shall develop a resilience action plan for the State Highway System based on current conditions and forecasted future events. The goals of the action plan must be to: (a) Recommend strategies to enhance infrastructure and the operational resilience of the State Highway System that may be incorporated into the transportation asset management plan. (b) Recommend design changes to retrofit existing state highway facilities and to construct new state highway facilities. (c) Enhance partnerships to address multijurisdictional resilience needs.
(2) The resilience action plan must include all of the following: (a) An assessment of the State Highway System to identify roadway facilities and drainage outfalls that may be subject to vulnerabilities associated with tidal, rainfall, the combination of tidal and rainfall, and storm surge flooding, including future projections of sea level rise, using existing data for current and forecasted future events. As part of the assessment, the department shall, using the most up-to-date National Oceanic and Atmospheric Administration precipitation frequency and sea level rise data, do all of the following: 1. Synthesize historical and current infrastructure resilience issues statewide. 2. Evaluate alternatives for retrofitting existing systems and infrastructure. 3. Develop prioritization criteria for resilience project identification. 4. Develop a prioritized resilience needs project list, in addition to existing projects within the work program, with the associated costs and timeline. 5. Develop a statewide database identifying and documenting those assets vulnerable to current and future flooding. The department shall develop a cost estimate and schedule to enhance existing data to include site-specific details and existing criteria to improve the needs prioritization. (b) A systemic review of the department’s policies, procedures, manuals, tools, and guidance documents to identify revisions that will facilitate cost-effective improvements to address existing and future State Highway System infrastructure vulnerabilities associated with flooding and sea level rise. (c) Provision of technical assistance to local agencies and modal partners on resilience issues related to the State Highway System and the deployment of local and regional solutions.
(3) By June 30, 2023, the department shall submit the resilience action plan to the Governor, the President of the Senate, and the Speaker of the House of Representatives. Every third year on June 30 thereafter, the department shall submit a status report reviewing updates to the action plan and the associated implementation activities.
