2.0 Policy Package


Public greenspaces, from parks to trails to public commons, help families be healthier in body and mind and keep our environment thriving. Simply walking or sitting for about 15 minutes in a park can significantly improve daily mental health. Greenspace policies ensure all families, not just a few, have access to public land, nature, and their benefits.

The Greenspace Challenge

  • Access to greenspace, including community schoolyards, public parks, walking trails, and other open spaces, is associated with improved mental health and sense of well-being among city residents.
  • Other benefits associated with Greenspace include reduced violence, decreased mortality, lower heart rate, improved attention and mood, and a higher likelihood of physical activity.
  • Neighborhoods that were historically subjected to redlining, the systematic practice of denying loans and other resources to people based on their race or ethnicity, tend to have significantly less tree cover and experience hotter temperatures than non-redlined neighborhoods.

A Healthy Solution: Greenspace

  • Improves Mental Health — Parks help everyone have a healthier mind and body. When a Philadelphia project turned vacant lots into “pocket parks,” feelings of depression decreased among residents in those neighborhoods compared to residents in other neighborhoods.
  • Helps the Environment Thrive — Tree coverage helps cool neighborhoods and reduce heat-related illnesses for residents — benefits that can extend as far as a half-mile from park boundaries.
  • Cuts Pollution —Green infrastructure can reduce runoff and filter out up to 95% of storm water pollutants.
  • Saves Lives — A $100 increase in county-level per capita investment in parks and recreation was associated with 3.4 fewer deaths per year per 100,000 people from 1980-2010.

CityHealth partners with the Trust for Public Land in support of this policy.
