As new subdivisions, strip malls, supercenters and commercial office parks sprawl across the country, local officials face the difficult task of balancing the potential economic benefits of growth against the needs of the existing community, including the need for open space.
In this context, "open space" may include small areas within communities or larger tracts on the perimeter. In either case, open space can provide opportunities for sports and recreation, for citizens to escape from the pressures of everyday life, for wildlife to find habitat and refuge, and for plants and soil to assist in the removal of toxins from our environment. Careful management of open space helps ensure that prime farm and ranch lands are protected, flood damage is mitigated, carbon capture is maximized, and clean drinking water supplies are maintained and recharged.
