The 1999 NRI, prepared by volunteers, was based on the first Township NRI done by volunteers in 1974. The 2013 NRI was carried out by volunteer members of the Environmental Commission in consultation with the Township engineer, John Ruschke of Hatch, Mott, MacDonald, and the Township planner, Frank Banisch of Banisch Associates. The purpose of an NRI is to provide information to the Planning Board when considering development applications, revisions to the Master Plan and zoning, to developers so they can plan environmentally sensitive construction, to the Open Space Committee to show opportunities for open space acquisition, currently preserved properties and possibilities for creating and connecting trails, to the Board of Adjustment for evaluating variance applications, to the Township Committee when planning services, and to the Environmental Commission and other groups for planning activities. The environment of Chatham Township is dominated by the Great Swamp National Wildlife Refuge, which occupies about a third of the township. Most of the Refuge is wetlands; they are the remnant of a lake formed when the Wisconsin glacier melted ten thousand years ago. The wetlands don't stop at the border of the refuge; they extend into most of the township and up some of the eastern slopes. The two main environmental changes in Chatham Township between 1999 and 2013 were the redevelopment and infill of parcels and small subdivisions, with many modest houses being demolished and replaced with bigger homes ("McMansions"), and the preservation of large tracts of open space. With the recent acquisition of the Platt property over half of the Hickory section is preserved open space. Of Chatham Township's 9.4 square mile area over 40% is preserved as open space. There are other large open areas which are privately owned. Other significant environmental events in the period included the adoption of strict stormwater control regulations and the requirement by the New Jersey Department of Environmental Protection that its conservation easements on wetlands and wetland transition areas be recorded in the office of the Morris County Clerk. The first means that often lot grading plans can be required to include stormwater management features and the second means that a parcel can easily be checked for a wetland easement by searching the on-line Morris County database. The 1999 NRI gives information on changes in the Township between the 1970s and 1999 including the construction of the Tanglewood sewage treatment plant, the identification of an important recharge area lying roughly between Southern Boulevard and Shunpike Road for the Buried Valley aquifer, and studies showing increased stormwater runoff from development. This Natural Resources Inventory is a report of all the natural features in Chatham Township. It has chapters on history, geology and topography, hydrology, climate and air quality, soils, vegetation, wildlife, open space and land use, transportation and regional connections. Some independent reports are made available: Banisch Build- out Analysis, Banisch Walkway and Bikeway Plan, Apgar Report 1997 on the Rolling Knolls landfill. The NRI ___________________________________________________ Chatham Township Natural Resources Inventory 2013 Introduction 1 includes a discussion of each of the Township's 12 natural sections: Passaic River, Esternay, Orchard, Mountainview, Fairmount, Southern Boulevard, Averett, Moraine, Giralda Farms, Loantaka, Hickory, and Delta. The NRI includes 15 stand-alone maps with a description of each: the Buried Valley aquifer, conservation easements, contaminated sites, critical habitat for imperiled species, environmentally sensitive sites, geology, land use/land cover 1986 to 2007, open space, parcels with potential for development, slopes in percent, soils, stormwater recharge, streams requiring a 300 foot buffer, topography, and wetlands.

All three editions have been produced by volunteers, with extra assistance from Kathy Caccavale, who helped with the production of the 1999 NRI, from John Ruschke, Township engineer associated with Hatch, Mott, MacDonald, who provided consultant services for the 2013 NRI, and from Frank Banisch, Township planner associated with Banisch Associates, who provided much detailed data for the 2013 NRI. The environmental commission which sponsored the 2013 NRI update consisted of Nicole Hagner, Chatham Township Mayor Kathy Abbott, Chatham Township Committee liaison to CTEC Lou Caprioglio Steve Carroll Pat Collington, Vice Chair Frank Esposito Shankar Krishnan Matt Palmer Subashree Rajagopal Megan Schaaf Dot Stillinger, Chair Carolyn Scannelli, Secretary The environmental commission NRI subcommittee which supervised all the work and created most of the content consisted of Steve Carroll, Shankar Krishnan, Matt Palmer, Dot Stillinger. We acknowledge with grateful thanks the 1999 mayor of Chatham Township and the members of the 1999 Environmental Commission whose efforts produced the 1999 Natural Resources Inventory: Joseph Reilly, Mayor 1999 Abigail Fair, Township Committee Liaison Keith Savel, Chairman Gregg Williamson, Vice Chairman
