8 Status Received and addressed over 500 comments from about 10 agencies (federal, state, local) Incorporated feedback to address: Reorganization of report (HRTPO/HRPDC) Technical specs for bridges (e.g., FHWA, VDOT) Consistency in asset information detail Right-of-way (ROW) costs (utilities/fhwa) Floodplains 8

9 Findings Assets and Data Significant asset information for bridges and roads Collected and continue to receive information regarding asset sensitivities to extreme weather 9

10 Findings Indirect Impacts Data available for Key economic sectors in the region Critical infrastructure facilities Right-of-Way Considerations Social vulnerabilities 10

17 Why Hampton Roads? Vulnerable- 2 nd Only to New Orleans for SLR and storm surge Federal/Military Importance- Nation s largest concentration of federal facilities and world s largest naval station (NSN) Extensive Transport Network- High density of multi-modal transportation infrastructure Flooding for Hampton Roads and Norfolk ( )

18 Augments Gulf Coast 2: Vulnerability Assessment & Adaptation 18

19 Methodology and Status Current Task (1) Developing a baseline of the transportation system : Modal assets: size, scale, geographic location, function Asset condition, structural integrity, asset vulnerabilities and exposure Summary of HR studies on exposure, impact, adaptation, indirect consequences Tools and resources for economic quantification Future Tasks (9/16-8/31/17) Task 2: Determining a methodology for estimating future costs using different scenarios and time scales Task 3: Small-scale pilot analysis using different scenarios and time scales Task 4: Region-scale using different scenarios and time scales 19

20 Outreach and Collaboration Intensive consultations with HR Pilot Project (Pilot) over a two-year period (20 meetings). Supports HR Pilot (2015): Planning activities need to address the c/b of proposed actions to aid in decision making. Presented at the three HR forums 20

21 Pathways Forward Pathway 1: Economic impact analysis of direct/indirect consequences associated with coastal flooding affecting transportation facilities. Engage VDOT/HRPTO/Local Stakeholders to test appropriate and robust economic methodologies that identify direct economic costs, economic drivers (e.g., tourism) and indirect consequences Consider potential adaptive strategies to reduce economic costs associated with coastal flooding. Pathway 2: Pathway 1 + Incorporating the findings into existing transportation asset management system Identify entry points to which the economic quantification study can link into the existing transportation asset management (TAM) system Such an analysis allows for potentially actionable and implementable results such as providing costeffective planning for developing an action plan to reduce climate-related risks. 21
