Resultados

The objectives of this project were to provide a comprehensive analysis of spatial-temporal variability of average and extreme historical precipitation trends and to assess future extreme precipitation changes for multiple planning horizons in the 21st century, i.e., 2040, 2060, 2080, and 2100, by considering the effects of a changing climate. Specifically, the project aims to use climate model projections to enable analysis of precipitation related risks to infrastructure and for identifying the need for additional investments in flood resilient landscapes. A broader understanding of past precipitation patterns is necessary for optimizing future demands on stormwater infrastructure, particularly when combined with a warming climate and regional population growth.

The main project outcomes were as follows:

  1. Analysis of historical precipitation patterns and changes.
  2. Incorporation of future precipitation changes in flood engineering design standards across Northern Virginia.
  3. Development of an adaptive framework/strategy for the application/replication of these changes by local watershed planners and engineers.
  4. Recommendations for how the information can be used to create flood resilient landscapes and infrastructure.

Descripción

The northern Virginia region is among the most diverse regions in the United States and serves as a global gateway for the state of Virginia. As part of the National Capital Area, Northern Virginia is growing faster than 37 other states. The Northern Virginia Regional Commission (NVRC) serves as a council of governments for 13 local governments and 2.4 million people across northern Virginia. There is a need in the region for actionable and comprehensive plans to advance climate, energy, and sustainability priorities.

The NVRC and its 13 members, in partnership with the Virginia Coastal Zone Management Program, is working towards the development of a “Resiliency Roadmap” to help the region absorb, recover from, and more successfully adapt to adverse events emanating from extreme weather events and climate-related hazards. Since November 2016, an NVRC-convened team comprised of technical and policy experts from the region’s governmental, commercial, academic and civil society sectors has met five times to assess place-based effects of climate change stressors on the natural and built environment. Among the core environmental stressors confronting the region, heavy precipitation events and the effects on stormwater infrastructure (especially within the context of capital improvement infrastructure planning) was identified as a key priority. Northern Virginia, however, lies between two regions (the northeast and southeast) highlighted the in the National Climate Assessment, each with its own climate projections.

The Project:

NVRC seeks to partner with a local scientist to better understand regional vulnerability scenarios to flooding and runoff based on a comprehensive look at precipitation, population and land use/land change projections for the region. Data for past, current, and future projected rainfall patterns in the northern Virginia region will be integrated with population projections (and development plans, where available) to produce probability statements, scenarios, or GIS layers that can be used by city and county-level planners to help inform future needs for and demands on stormwater infrastructure while considering climate change and regional growth.

In that capacity, he co-leads the NVRC’s regional climate mitigation, energy and resiliency programs and manages NVRC’s international environmental partnerships. He helped co-launch the first formal climate and energy partnership between the 40 largest U.S. and European metropolitan regional councils, co-initiate the Transatlantic Climate Bridge, co-launch the Alexander von Humboldt Foundation’s “Cities and Climate” Network and co-develop the Transatlantic Urban Climate Dialogue with the Freie Universitaet of Berlin (Germany). Prior to working for NVRC, Dale spent approximately 20 years at the Office of International Affairs, U.S. Environmental Protection Agency, Washington, as the program manager for western Europe and urban environmental programs. Dale has a Ph.D. in environmental design and planning from Virginia Tech University, an M.S. in Cartographic and Geographic Science from George Mason University, an M.G.A. in Government from the University of Pennsylvania, and a B.A. in International Relations from the University of Redlands.
