Michael Schnatzmeyer

With a degree in Environmental Design (CU Boulder), Michael has evolved a systems-thinking worldview, applying a multi-solving approach to a wide variety of initiatives including climate education, entrepreneurialism, planning, walkability, cleantech, renewables, co-housing, and affordable housing. He has co-founded five nonprofits including Sustainability, Maker, and Start-Up groups.

Mike worked with the Center for New Urbanism and the CU Graduate School of Planning to catalyze a re-envisioning of the St. Vrain River corridor, currently reflected in Longmont's $140 million Resilient St. Vrain flood-mitigation project. He continues to promote a "climate-smart-city" vision via community outreach and education initiatives embodying biophilic, smart-growth principles. Mike also brings a knowledge of Longmont area issues to the IPG.

Rebecca has been an environmental activist for over 20 years. She was the chair of the Indian Peaks Group for eight years; now she is the vice chair. Along with many other activists, Rebecca has helped Boulder County and the state of Colorado rein in oil and gas activity and work to address climate change. She also works to reduce light pollution and pesticide use. Rebecca established and runs the Indian Peaks Group's organic fruit sale and its organic Plant Exchange. She believes that equity, diversity, and inclusion matter in every facet of life and thus supports the Sierra Club's published policies on affordable housing, density, and infill.
