Threat Assessment for Smart Conservation

The Development Threat Assessment for SmartConservation, which analyzed the 5-county area surrounding Philadelphia, was compiled by the Delaware Valley Regional Planning Commission for the Natural Lands between 2002 and 2003. The data used was already partially or completely available, allowing the completion of an analysis that would have otherwise been too costly and time-consuming. Five subcomponents of data were used: trend friction map, employment center travel time analysis, building activity, vulnerability index & sewer service areas.
