According to the Association of New Jersey Environmental Commissions, an Environmental Resources Inventory (or ERI), is “a compilation of text and visual information about the natural resource characteristics and environmental features of an area.” The ERI is a report based upon factual information, and provides a municipality with a baseline documentation for assessing environmental issues. It is an important planning tool for environmental commissions and planning boards. It is recommended that the ERI be adopted as part of the municipal master plan, specifically as part of the conservation element (this is envisioned to be the case in Bordentown City). The ERI is a living document, which should be updated periodically as new information becomes available and assessment techniques become more refined. Two New Jersey state laws, the Environmental Commission Enabling Legislation (NJSA 40:56A) and the Municipal Land Use Law (NJSA 40:55D-1), give environmental commissions the authority and responsibility for conducting and maintaining ERIs. An ERI includes text, maps, tables, photos and figures that describe and quantify the local environment. Basic ERI information, including such topics as location, topography, climate, soils, geology, hydrology, vegetation, wildlife and land use, serves as the foundation of the document. The inclusion of additional information such as air quality, transportation, historic resources, noise and regional relationships serves to create the most comprehensive report possible. Finally, sections such as a glossary, references and appendices ensure that the information presented in the ERI is accurately and completely documented. An ERI can be used in a variety of ways. In Bordentown City, the ERI will be used as a guide in the site plan review process; help prioritize open space acquisition; save tax dollars by helping to prevent costly environmental problems; assist in the municipal land use planning process; serve as a reference for municipal ordinances and best management practices; and provide an educational resource for residents. Hardcopies of the ERI will be available at City Hall and the Bordentown Public Library. Additionally, a limited number of PDF files on CD-ROM will be made available to the public. The Bordentown City Environmental Commission has been working on the ERI since its inception in 2002. It was completed without the customary assistance of private consultants, at minimal cost to the City. Environmental Commission members brought their expertise, passion and knowledge of the local environment to the project, and in the process gained a greater understanding of the local environment. The very features that drew early settlers to this confluence of waterways in the 17th century continue to define Bordentown City as a special and unique place for its 21st century residents. It is hoped that the Bordentown City Environmental Resource Inventory will serve current and future residents well as the City approaches its 325th year as a place of settlement on the bluffs of Crosswicks Creek. vii THE NATURAL ENVIRONMENT Location Bordentown City is located on the western edge of central New Jersey, just southeast of Trenton, along a bend in the Delaware River, where the flow direction shifts from southeast to southwest. It is in the northernmost corner of Burlington County, and is bordered by: • Mile Hollow Run(and Bordentown Township) to the northeast; • Bordentown Township to the east and south; • Blacks Creek (and Bordentown Township) to the southwest; • The Delaware River (and Pennsylvania) to the west; • Crosswicks Creek (and Hamilton Township, Mercer County) to the northwest. Physiography New Jersey can be divided into four major geomorphic or physiographic provinces, each characterized by rocks (or sediments) of similar type, origin, and age, similar landscapes, and a general northeast/southwest trend. (See the Geologic Map of New Jersey on page 3.) Bordentown City is part of the Coastal Plain, which covers 3/5 of the area of the state, southeast of a line from Trenton to Carteret. It is a broad, flat to gently undulating, low-lying area, composed of a wedge of unconsolidated sediments gently dipping southeastward. This wedge also thickens to the southeast, from 50 to 150 feet along the Delaware River, to 4,500 feet at Atlantic City, to 40,000 feet thick 50 miles offshore. Coastal plain sediments include deltaic and marine deposits of Cretaceous to Tertiary age (145 to 1.75 million years ago), resulting from fluctuating sea level; a thin veneer of fluvial sands and gravels of Pliocene and Miocene age (23 to 1.75 million years ago); and alluvial, beach, swamp, eolian, and tidal marsh deposits from the Quaternary Period (the last 1.75 million years). Bordentown City is located in the Inner Coastal Plain subprovince, characterized by higher elevations, more local topographic relief, and generally finer textured deposits than found in the Outer Coastal Plain. Topography Most of Bordentown City is nearly level to gently sloping, with elevations between 50 and 100 feet above sea level. Steep slopes are found along stream channels cut by Thorntown Creek, Mile Hollow Run, Love Bridge Run, and Blacks Creek, and on 50 foot bluffs above Crosswicks Creek. Tidal marsh deposits along the Crosswicks and Blacks Creeks are less than 10 feet above sea level. 1 Regional Map 2 Geologic Map of New Jersey 3 Climate The global weather patterns that take place based upon the Earth's rotation, tilt and land/water distribution are the factors responsible for our climates.
