INTRODUCTION This Greenways and Open Space Element of the East Amwell Township Master Plan is a guide for a township-wide network of preserved open spaces, including farmland, recreation, and conserved forested areas; and stream corridors, called greenways. Greenways and open spaces are valuable for many reasons. They provide habitat and migration corridors for wildlife in a State where such habitat is being lost to development rapidly. They can provide a visual respite, preserve community character, and also provide passive and active recreational opportunities. They serve to protect valuable, irreplaceable resources and are, therefore, a useful tool in planning potential development. Greenways and open spaces also help reduce the amount of Township budget required for public services and other infrastructure and, therefore, may help limit tax levels. East Amwell is unique in that the majority of the Township is characterized by one or more important natural resources. It also contains historic and recreational features. The stated objectives of East Amwell's Greenways and Open Space Plan project are to promote its goals of farmland preservation, protection of stream corridors, water supplies, and forest resources, and preservation of its rural environment. This Plan will also help guide land use policies, recommend regulatory actions in keeping with the agricultural, rural and historic nature of East Amwell Township, allow qualification for "fast track" Green Acres Program review (and financing), and target properties for preservation and acquisition. This Greenways and Open Space Plan seeks to expand public recreation opportunities which are respectful of the sensitive character of natural lands, farmlands, and cultural resources. Public access is currently limited to existing Township and County recreation and open space lands and lands preserved by non-profit organizations. Amy S. Greene Environmental Consultants, Inc. was hired to update the Greenways and Open Space Element of the East Amwell Township Master Plan. The funding for the project came partially from a grant from the New Jersey Department of Environmental Protection (NJDEP) Office of Intergovernmental Affairs, Environmental Services Program and partially from Township funding. Through the use of various digital mapping sources, as well as several existing texts, ASGECI has assembled a compilation of maps that include natural, agricultural; recreational, and historic resources of the Township. The main mapping source was Hunterdon County Division of Geographic Information Systems through a special Spatial Data Distribution Agreement (see Appendix A). This compilation is the property of East Amwell and has been made in ARC-VIEW GIS format. The Township has the ability to update the information as needed, and to overlay the various layers to make planning decisions and perform various analyses. 1 II. METHODS Much of the information provided in this report is a result of analysis of data provided by either Township sources, NJDEP Geographic Information Systems (GIS) Resource Data, or the Hunterdon County, New Jersey, GIS Digital Data. The mapping for this project was done in ARC-VIEW 3.1 format. Mapping included the identification of natural resources (such as wetlands and forests), approved historic districts, and recreational, and agricultural resources. Figure 3 indicates existing Preserved Open Space and Greenways. This map indicates parcels that are currently preserved, as well as those that are expected to be preserved in the near future due to current preservation negotiations. Once resources were mapped in GIS, each resource was further divided into meaningful categories. For example, the forested area coverage was divided into contiguous forests either greater than or less than 100 acres ( 40 hectares). These two categories were chosen because certain wildlife species (including certain endangered/threatened species) require large tracts of contiguous forests. Similar categories were used for other resource coverages. In several cases, the categories were chosen in a way that would cause a clumping effect, creating concentrated areas of higher value resources, rather than a scattered pattern of resources. After the coverages were devised, a weighted ranking system was developed in an effort to identify high-ranking parcels, and groups of high-ranking parcels, for preservation planning (see Appendix B). This ranking system was approved by the East Amwell Environmental Commission. The ranking system recognizes the Township's primary commitment to agricultural preservation. Secondarily, the Township has strong commitments to expanding its recreational opportunities, preserving historic resources,

End-Sheets NJ State Parks Adopt a Crag 2 www.climbnj.com CRI 2007 Access NJ Introduction In a State known for its beaches, meadowlands and malls, rock climbing is a well established year-round, outdoor, all weather recreational activity. Rock Climbing “cragging” (A rock-climbers' term for a cliff or group of cliffs, in any location, which is or may be suitable for climbing) in NJ is limited by access. Climbing access in NJ is constrained by topography, weather, the environment and other variables. Climbing encounters access issues . with private landowners, municipalities, State and Federal Governments, watershed authorities and other landowners and managers of the States natural resources. The motives and impacts of climbers are not distinct from hikers, bikers, nor others who use NJ's open space areas. Climbers like these others, seek urban escape, nature appreciation, wildlife observation, exercise and a variety of other enriching outcomes when we use the resources of the New Jersey’s State Parks and Forests (Steve Matous, Access Fund Director, March 2004).

  • Land, Natural Resources, and Geology
    Land and Natural Resources of West Amwell By Fred Bowers, Ph.D Goat Hill from the north Diabase Boulders are common. Shale and Argillite outcrops appear like this. General Description of the Area West Amwell Township is in Hunterdon County, New Jersey, USA. It is a 22 square mile rural township with just over 2200 people, located near Lambertville, New Jersey. It is one of the more scenic parts of the New Jersey Piedmont. It is identified in red on the maps below. West Amwell is characterized by most people as a "rocky land." One of the oldest villages in the township is called Rocktown. If you visit or look around the township, you cannot avoid seeing rocks and outcrops like those pictured above. Hunterdon County New Jersey, with West Amwell located at the southern border, marked in red The physiographic provinces of New Jersey, with Hunterdon County and West Amwell marked in red Rocks The backbone of West Amwell Township's land is the Sourland Mountain; a typical Piedmont ridge formed by a very hard igneous rock called diabase or "Trap Rock." The Sourland Mountain ends at the Delaware River below Goat Hill which you see in the picture above, looking south from the Lambertville toll bridge. To the south and north of the diabase, shale and argillite occurs, and these rocks form the lower lands we know of as Pleasant Valley and the shale ridges and valleys you see from around Mt. Airy. In order to appreciate the rocks and the influence they have on the look of the land, it is useful to have a short review of rocks.

  • 1 Alexauken Creek Wildlife Management Area Biological Inventory Report Washington Crossing Audubon Society Introduction The
    Alexauken Creek Wildlife Management Area Biological Inventory Report Washington Crossing Audubon Society Introduction The New Jersey Department of Fish and Wildlife recently purchased a tract of approximately 415 acres along Alexauken Creek in West Amwell Township to create the Alexauken Creek Wildlife Management Area (ACWMA). In the summer of 2002, Washington Crossing Audubon Society (WCAS) was contacted by Jamie Kampf and Hal Shute, neighbors of ACWMA, and invited to take a tour of the property. WCAS was also asked to consider conducting a biological inventory of the property and making recommendations for its management, based on information gathered in the inventory. On June 5, 2002 WCAS current and former board members Hannah Suthers, Pat Sziber, Rick Dutko and Herb Lord joined Hal Shute, Jamie Kampf and Gary Robinson for a tour of the property, and agreed that WCAS would conduct the study and provide a report in early 2004. The following sections provide a description of the property, a description of how the inventory was conducted, summaries of the results, and our recommendations for management of the property.
