We all need green, open spaces as a refuge after busy days with busy schedules. We also need them for their environmental benefits: clean air, clean water, and reduced flooding to name but a few. Whether small or large, all communities should make a commitment to protecting open spaces. Here are some innovative methods used by communities around the country. Parks are one of the most important community spaces because they promote social interaction. In response to suburban sprawl that has taken people away from central cities and main streets and put them in suburban subdivisions, cars and shopping malls, urban parks are seen as a way to bring people back downtown and back together.
