Mission

OSA works with the City of New York and the community to ensure the North Brooklyn's Parks meet the needs of the neighborhood, such that they can be enjoyed today and for generations to come.

What We Do

Open Space Alliance for North Brooklyn (OSA) focuses on keeping the parks of North Brooklyn beautiful and active. We do this through:
- Our Green Team, who helps clean the parks and maintain landscaping.
- Bringing free programs to the parks (including concerts, movies, & fitness classes)
- Hosting volunteer events
- Coordinating small capital repairs
- Community Outreach
- and more
