In Denver, the Platte Farm Open Space provides an example of a successful community-led project that transformed a former brownfield site in a working-class neighborhood into a vibrant community amenity. "Through a process of remediation, contaminated land was replaced with fresh layers of topsoil, and is now home to prairie habitat that attracts foxes, rabbits, birds and butterflies." The project was "a collaborative effort between the community members of Globeville, the city of Denver, and Groundwork Denver, a nonprofit organization that works to create green spaces to help improve community health." 

While several factors—including the city of Denver's recent commitment to create an open space within a 10-minute walk of all residents—came together over close to a decade and a half to make Platte Farm a reality, urban park advocates know they face a long uphill battle to achieving park equity in Denver and elsewhere. "Limited financial resources for environmental justice organizations, green gentrification, and redlining are among the many obstacles that have resulted in inequitable access to green space, worsening health disparities among urban communities."

Research increasingly shows that access to parks and urban vegetation have positive effects on physical and mental health. "Benefits may include improved cognitive development and functioning, reduced symptom severity of attention deficit hyperactivity disorder, reduced obesity, and positive impacts on mental health." Many of these are related to the opportunity for higher rates of physical activity in neighborhoods with more access to green spaces, signaling that park access, more than a pleasant amenity, is an essential component of healthy neighborhoods.
