Flood Awareness Week Lunch and Learn Webinars 

Virginia Flood Awareness Week, March 12-18, 2023, encourages Virginians to learn about their flood risk and protect the life they’ve built with flood insurance. Just an inch of water entering a home can result in as much as $25,000 in damages. Yet only 3% of Virginians have flood insurance. Flood Awareness Week seeks to educate the public about protecting their property by purchasing a flood insurance policy, which on average in Virginia costs between $400 and $1000 annually.

Comprehensive Flood Mitigation Planning: Exchange of Lessons Between Alexandria, Virginia and Hamburg (Germany)

March 21, 2023 | 12 - 1:15 PM

Like many local governments located along coasts, the City of Alexandria, Arlington County, Fairfax County and Prince William County must plan, design, budget and maintain long-term flood protection programs. But the urgent challenges from floods emanating from sea-level rise and more frequent and intense storm events create tension for local governments who must choose between high costs and effectively performing flood mitigation systems. 

Across the Atlantic, the City of Hamburg has pioneered the planning and application of advanced comprehensive flood mitigation planning systems at the micro- and macro levels. Hamburg’s decades of planning reflect a unique fusion of active and passive engineering, storm-surge protection, stormwater conveyance, monitoring, multiple self-deployable flood barriers. The union of these planning, design and engineering tools has parked Hamburg at the center of climate resilient planning.  

The City of Alexandria, NVRC, and George Mason University’s Institute for a Sustainable Earth and Virginia Climate Center held a webinar on March 21, 2023 to share local long- and short-term planning processes for flood protection and climate resiliency. The discussion featured Mr. Uwe A. Carstensen, a consultant for the City of Hamburg's “HafenCity” project, as well as Dr. Daniel Medina and Mr. Matthew Landes from the City of Alexandria, VA with presentations on their work with sustainable flood mitigation and opportunities for collaboration and lessons learning across the Atlantic.
