Parks raise the economic value the neighborhood. Both homeowners and businesses like to be near a thriving park. Fees for recreational activities and an increased tax base easily cover the costs of building and maintaining parks. Even in very urban areas, developers can often be persuaded to build parks in return for permits, and it's a win-win, since the park improves the value of the development.

Parks improve water and air quality, protect groundwater, and prevent flooding. They provide buffers to development. They provide a place for recreation and exercise and reconnecting with nature for children and adults alike -- and often for pets, too. Organized adult-supervised activities at parks keep children and teens out of trouble, reducing juvenile delinquency and crime.
