The Mill Creek Alliance (Alliance)
is a non-profit organization formed in 2018 through the merger of two successful conservation groups: The Mill Creek Watershed Council of Communities and Groundwork Cincinnati-Mill Creek.

A Groundwork USA Trust & Council of Communities

The mission of the Alliance is to empower Mill Creek communities to protect and enhance the value of the Mill Creek, its tributaries, and watershed. Through inclusive, meaningful community engagement and collaborative action, the Alliance strives to create a Mill Creek watershed that is a healthy ecosystem where thriving people and communities live, work, and play.

The Alliance’s provides comprehensive solutions to many of the problems faced by our constituent communities. Our multi-faceted approach includes:

  • Developing intergovernmental long range planning projects that recover & improve the watershed corridor and support community & economic development (restore habitat, reduce flood damage, stabilize stream banks, solve stormwater challenges, and promote invasive species control)

  • Promoting green workforce development and supporting emerging environmental leaders in affiliation with Groundwork USA.  

  • Improving water quality through stream restoration, water quality management and research, reintroduction of native species, and development of public green spaces (edible gardens, trails, and more)

  • Encouraging community engagement with the watershed through recreation and community outreach programs, school programs, volunteer events (clean ups, tree plantings, edible gardens, trail maintenance), and environmental education programs.

  • Transforming the natural and built environment of marginalized communities by offering restoration services.

  • Transforming neglected land and waterways into assets that our neighborhoods need to be healthy and resilient


[The Mill Creek Watershed Council of Communities and Groundwork Cincinnati have officially merged into the Mill Creek Alliance. As we work to merge our two teams we hope you will be forgiving of any overlap or confusion in communication with the organizational name. We will keep you updated on these changes as they happen.]
