Overview

A team of researchers from Rutgers and Rowan Universities have recently completed a study examining New Jersey’s urban growth and land use change over the past three decades. The research team led by Richard Lathrop (Rutgers University) and John Hasse (Rowan University) have collaborated on a number of studies tracking New Jersey’s changing landscape. The team relies heavily on the NJ Department of Environmental Protection’s Land Use/Land Cover Change (NJLULCC) data set.

The most recent data available (between the year 2012 and 2015) reveals that New Jersey has expanded the amount of urban land at a rate of 3,464 acres of new urban development per year. This rate represents a continuation of the trend of decreasing urban development initiated during the Great Recession of 2008.  Not only was there a dramatic slowdown statewide in overall acres developed, the residential footprint shrank in relative proportion when compared to other urban land uses.

The most recent land use data also reveals a major departure from the sprawling trends of the previous decades in favor of delineated smart growth zones.  While sprawling large-lot development was not completely defunct, consuming more than half of the residential land developed, it became a smaller piece of the residential development pie. Higher-density residential types significantly increased their proportion of land development acres as well as their proportion of population housed. More units were built on less land, signaling a significant shift toward denser residential development.  

The report notes that the conversion of green space to new urban development in New Jersey has continued to slow from its historic high pace of new urban development in the 1990’s and 2000’s. While the rate of farmland converted to urban land uses has decreased quite dramatically in recent years, the conversion of upland and wetland forests has shown an uptick. This loss of forestlands is concerning as these ecosystems play a critical role in removing carbon from the atmosphere and storing it in wood and forest soils.

New Jersey has also lost thousands of acres of coastal salt marsh over the past three decades due to rising sea levels and coastal erosion. These marshes are important fish and wildlife habitat and serve as important buffers against coastal storms.
