Nearly two-thirds, or 65 percent, of developed land in New Jersey is used for residential housing, according to a study recently released by the Geospatial Research Laboratory of Rowan University. This represents a remarkable 26.8 percent increase since 1986, when the first State Plan for development was authorized. Unfortunately, most of the development since that time has been residential housing on a half-acre or more, which is in direct conflict with recommendations of the plan. The study found that between 1986 and 2007, a total of 227,198 acres went from the open space land category, such as farmland or forests, to residential development. The study says this equated to 22.4 football fields of new residential housing every day in that time.
