We envision lower Four Mile Run as a cherished community resource and a model for natural lands stewardship in an urban setting.

Our mission is to promote nature, culture, and community at lower Four Mile Run through restoration, advocacy, recreation, and education.

Our Annual Reports summarize our impact and are available online. See our profile page on GuideStar for additional information.

 The Four Mile Run Conservatory Foundation is a 501(c)(3) non-profit corporation and volunteer organization formed in 2016 following years of community efforts to beautify and improve Four Mile Run Park. Learn about those efforts here.
