Groundwork Hudson Valley is an environmental justice non-profit that works with communities to improve their physical and social environment. This is done by collaborating on projects, among them: turning dangerous vacant lots into community gardens, planting trees, replacing graffiti with murals, and forming alliances within the community. Some of these projects are done through school programs and many of them are intergenerational. They are dedicated to environmental stewardship and community empowerment. All of the projects engage local residents in hands-on projects, from design to planting.
