Bronx River Alliance

What Bronx River Alliance does

The Bronx River Alliance is a 501(c)(3) nonprofit organization incorporated in New York in 2001 that serves as the designated coordinator and sole advocate for the protection and restoration of the Bronx River, NYC's only freshwater river. Operating from River House at Starlight Park in the South Bronx, the Alliance runs a portfolio of interconnected programs spanning ecological restoration (Project WASTE trash removal, Project Water DROP pollutant detection, water quality monitoring, invasive species removal), public access (the 8-mile Bronx River Greenway, paddling programs, Concrete Plant Park, Shoelace Park), environmental education (the Living Laboratory outdoor STEAM curriculum, Bronx River EELS youth internship), and community engagement (Conservation Crew, the Foodway edible food forest, the annual Amazing Bronx River Flotilla). The organization has approximately 20-25 staff and works in close partnership with NYC Parks, over 100 partner organizations, and federal/state agencies including the EPA, NPS, and U.S. Army Corps of Engineers.

The Alliance's business model is grant- and donation-funded, with operating revenue drawn from a diversified mix of individual donations, membership dues across four tiers ($25-$250 annually, substitutable with volunteer hours), $150-per-program educational field trip fees (with 20% discounts for environmental justice schools within 2 miles), corporate sponsorships, gala ticket sales, and — most significantly — government and foundation grants. It serves four primary customer segments: Bronx and Westchester community residents engaged through events and membership, K-12 schools and students accessing the river as an outdoor learning laboratory, environmental advocates and volunteers contributing labor and citizen science, and corporate and institutional partners supporting through ESG-aligned funding and volunteering. Technology infrastructure is operational rather than productized, relying on Salesforce, Mailchimp, Calendly, Google Forms, and the iNaturalist citizen science platform.

Capital delivery has historically been substantial: the Alliance helped catalyze over $30M in restoration funding between 2003-2007 through Congressman Jose E. Serrano and partners, completed a $10M Concrete Plant Park transformation in 2009, and brought the River House headquarters online in 2020. The current leadership team is led by Executive Director Siddhartha Sanchez, following the transition from former Executive Director Maggie Greenfield.
