Lenni Armstrong talks about the Depaving Parties she organizes in collaboration with Somerville Climate Action. She works with residents who want to transform paved areas of their yards into green spaces or permeable walkways and driveways. Urban depaving helps keep the watershed clean and promotes healthy neighborhood ecosystems. Also, Depaving Parties are fun and build community! Presented at the Urban and Suburban Carbon Farming to Reverse Global Warming conference at Harvard University on May 3, 2015, organized by Biodiversity for a Livable Climate. www.bio4climate.org
