Groundwork USA is the only network of local, people-centered organizations devoted to transforming the natural and built environment of under-resourced communities -- a national enterprise with local roots, working at the intersection of the environment, health, equity, youth empowerment, and civic engagement. Through inclusive, meaningful community engagement and cross-sector collaboration, local Groundwork affiliates called “Trusts” transform neglected land and waterways into assets that under-resourced neighborhoods need to be healthy and resilient while building community capacity to improve systems. Groundwork USA supports this dynamic network and advances the field of equitable development through national technical assistance and learning network programs for local practitioners. Our work is supported by the United States Environmental Protection Agency, the National Park Service, the United States Department of Agriculture, and other partners.
