MODERATOR: CATHY WHITLOCK, MONTANA STATE UNIVERSITY Continuing the discussion of subnational assessments from the previous session, Whitlock noted that this session will consider more targeted assessments done for particular sectors or regions. The panel members' experience spans the Southeast Florida Regional Climate Change Compact; the Denver Water Department's climate adaptation program; sea level rise issues in the Hampton Roads, Virginia, area; and population dynamics and climate adaptation in the Tennessee Valley.

Jurado described how the county adopted a future conditions map series that provides the framework for integrating resilience standards in licensing and project design requirements. The county has established targeted areas for resiliency standards, including drainage infrastructure, elevations for coastal flood barriers, and projected flood elevations, all relying on the SLR projections, estimates of changes in rainfall, and sophisticated hydrologic models.

This caused the water utility to consider a broader set of potential impacts that it could face by looking further back into history by using tree ring data, which suggested droughts well beyond the immediate hydrological record. Using this expanded record to look into the future, they undertook the Joint Front Range Climate Change Vulnerability Study (Water Research Foundation, 2012)

Other efforts include Norfolk receiving a grant from the Rockefeller Foundation 100 Resilient Cities Program,4 which supported the city having its own resilience officer and is supporting development of a Vision 2100 plan.5 This plan provides definitions for critical 3 Commonwealth Center for Recurrent Flooding Resiliency, "Hampton Roads Resilience Forum -- How the Region Works with Water," https://www.floodingresiliency.org/event-hampton-roads-resilience-forum-how-the-region-works-with-water/. 4 See the 100 Resilient Cities website at http://www.100resilientcities.org/.

The TVA infrastructure considered in the case study was limited to the Cumberland River basin, where fossil-based thermal power dominates, but significant electricity generation comes from hydropower and other sources. Under the heat wave projections and population growth assumed out to 2050, electricity demand increased by 87 percent, while reduced water flow, increased evaporation, and increased demands for cooling water could result in hydropower production of only 35 to 60 percent of its normal rates.

In concluding, Allen noted that many of the limitations of climate assessments have already been mentioned and included that many estimates of future losses are based on past examples but that future extreme events may be much more extreme. PANEL DISCUSSION Cathy Whitlock asked the panel to comment on techniques to communicate future scenarios effectively to infrastructure planners and decision makers that helped foster cooperation and collaboration.
