Designing Cities that Love Nature

Dr. Timothy BeatleyThursday, January 14, 7pm
RSVP required, click here to register

Join PWCA and UVA Professor Timothy Beatley for a conversation about the many ways in which cities are already profoundly natureful and biodiverse.

Urban design and planning that puts nature at the center is the most effective approach to building communities that are resilient, an especially urgent challenge in the era of climate change.

Discover the emerging concept of "Biophilic Urbanism" as an alternative global vision for how cities might develop in ways that make them profoundly resilient, i.e. able to respond to change.

Dr. Beatley believes that contact with nature is not something optional but is absolutely essential for a happy, healthy and meaningful life. This emerging new model overcomes the current physical (and mental) disconnect between nature and cities to the benefit of both.

Dr. Timothy Beatley is the Teresa Heinz Professor of Sustainable Communities, in the Department of Urban and Environmental Planning, School of Architecture at the University of Virginia.

The Barnes House: A History of Our Community with Bill Backus

Barnes HouseMonday, February 1, 7pm
RSVP required, click here to register

Join PWCA and local historian Bill Backus as we explore our county's diverse history through the lens of the Barnes House Historic Site.

Built in 1797 the Barnes house is an average Prince William County residence. But the people who lived here were anything but typical.

First used as a tavern, in the 1899 Eppa Barnes bought the house where he was born into slavery. Although the Barnes House has moved from its original location, the restored building highlights diverse history of Prince William County.

A native of Connecticut, Bill Backus graduated from the University of Mary Washington with a degree in Historic Preservation. Prior to his service with Prince William County, Bill has worked with the National Park Service at Vicksburg National Military Park and Petersburg National Battlefield. Working with the county for over 10 years, Bill currently serves as Preservationist/Curator.
