This parcels dataset is a spatial representation of tax lots for Essex County, New Jersey that have been extracted from the NJ statewide parcels composite by the NJ Office of Information Technology, Office of GIS (NJOGIS). Parcels at county boundaries have been modified to correspond with the NJ county boundaries and the parcels in adjacent counties.Each parcel contains a field named PAMS_PIN based on a concatenation of the county/municipality code, block number, lot number and qualification code. Using the PAMS_PIN, the dataset can be joined to the MOD-IV database table that contains supplementary attribute information regarding lot ownership and characteristics. Due to irregularities in the data development process, duplicate PAMS_PIN values exist in the parcel records. Users should avoid joining MOD-IV database table records to all parcel records with duplicate PAMS_PINs because of uncertainty regarding whether the MOD-IV records will join to the correct parcel records. There are also parcel records with unique PAMS_PIN values for which there are no corresponding records in the MOD-IV database tables. This is mostly due to the way data are organized in the MOD-IV database.The polygons delineated in the dataset do not represent legal boundaries and should not be used to provide a legal determination of land ownership. Parcels are not survey data and should not be used as such.The MOD-IV system provides for uniform preparation, maintenance, presentation and storage of property tax information required by the Constitution of the State of New Jersey, New Jersey Statutes and rules promulgated by the Director of the Division of Taxation. MOD-IV maintains and updates all assessment records and produces all statutorily required tax lists for property tax bills. This list accounts for all parcels of real property as delineated and identified on each municipality's official tax map, as well as taxable values and descriptive data for each parcel. Tax List records were received as raw data from the Taxation Team of NJOIT which collected source information from municipal tax assessors and created the statewide table. This table was subsequently processed for ease of use with NJ tax parcel spatial data and split into an individual table for each county.***NOTE*** For users who incorporate NJOGIS services into web maps and/or web applications, please sign up for the NJ Geospatial Forum discussion listserv for early notification of service changes.

Three classes of impervious surfaces--buildings, roads, and other impervious--were mapped for New Jersey through a semi-automated process developed using eCognition software. The automated feature extraction workflow used a Geographic Object-Oriented Image Analysis (GEOBIA) framework to extract the three impervious classes from the source datasets which include digital imagery, LiDAR point clouds and several vector data sets including Land use/land cover, road centerlines and hydrographic features, using a rule-based expert system.

The Hudson County Chromate Chemical Production Waste Sites are located throughout Bayonne, Jersey City, Kearny, Newark, Secaucus and Weehawkin in Hudson and Essex Counties. The New Jersey Department of Environmental Protection has identified over 160 sites that are contaminated with chromite ore processing residue, also known as chromate waste. The chromate chemical production waste has been found at residential, commercial and industrial locations. The more than two million tons of waste disposed of over the area were generated by three chromite ore-processing plants which operated for approximately 70 years between 1905 and 1971. The three plants, located in Hudson County, were owned and operated by:PPG Industries, Inc. (PPG) at its former chromium chemical production facility location at Garfield Avenue in Jersey City. The predecessors and subsidiaries of AlliedSignal, Inc. (Allied) previously located on Route 440 in Jersey City The predecessor and subsidiaries of Occidental Chemical Corp., Maxus Energy Corp. and Chemical Land Holding, Inc. previously located on the Belleville Turnpike in KearnyPPG, Allied and Occidental are collectively referred to as the Responsible Entities (REs).The chromate waste from the above facilities was used as fill in preparation for building foundations, construction of tank berms, roadway construction, filling of wetlands, sewerline construction and other construction and development projects. Chromate contamination has been found in a variety of places including the walls and floors of buildings, interior and exterior building surfaces, surfaces of driveways and parking lots and in the surface and subsurface of unpaved areas.Included in this GIS layer are those sites within Hudson and Essex Counties in New Jersey where chromate contamination of soil and/or ground water associated with chrome chemical production waste has been identified. This list of chromate waste sites include sites where remediation is either currently under way, required but not yet initiated, has been completed or that were originally deemed a chrome site but further investigation determined that chromate contamination was not present. Additionally, more chromate waste sites may yet be identified and accordingly are not included here. For further information contact NJDEP's Site Remediation Waste Management Program (SRWMP) lead program or the Licensed Site Remediation Professional (LSRP), based on the information provided in the Program attribute field. Contact information for SRWMPs lead program, where applicable, can be acquired at www.nj.gov/dep/srp/about/. Additional information regarding chrome site cleanups can be obtained through https://www.nj.gov/dep/srp/siteinfo/chrome/bkgrnd.htm.The Site Status attribute field will serve to identify the specific category associated with each chrome site. Specific attributes by which the layer is symbolized include the following:Active: Site is an active chrome cleanup case being remediated by one or more of the 3 REs Multi Contaminant: Site is an active chrome cleanup case that is being remediated by the responsible entity that owns the property on which the chromate waste contamination has been identified in conjunction with cleanup efforts for contamination associated with their operations or has agreed to address the chromium contamination present at their property.Post Remedial Monitoring: The chromate waste case has been closed with the issuance of a No Further Action (NFA) or Remedial Action Outcome (RAO) letter with soil and/or groundwater contamination addressed via an Institutional Control (Classification Exception Area for ground water and Deed Notice/Engineering Control for soil). Closed - Unrestricted Use: The chromate waste case has been closed with the issuance of a No Further Action (NFA) or Remedial Action Outcome (RAO) letter with no Institutional Controls required.Not a Chrome Site: Properties that were originally listed as chrome sites based on visual observation/past recollection but later found not to have chromate waste contamination present above standard following sampling.

Each natural waterfall in the state that was known to the NJGWS with a rise over run of approximately four feet to one foot of elevation or an approximate 75 % slope was visited and surveyed. The survey included getting the physical location of each waterfall, measuring the height of each waterfall and identifying the type of waterfall. There were far too many small waterfalls under four feet to locate and measure statewide, so these were not included in our survey of the state’s waterfalls. However, there were a few exceptions to this methodology. Three waterfalls were surveyed not adhering to the greater than four feet by one foot minimum threshold for inclusion into this report. These exceptions included a waterfall surveyed just under four feet at 3.79 feet. It was included since it was in a grouping of numerous other larger waterfalls on Dunnfield Creek in the Delaware Water Gap National Recreation Area. Also included in this report was the Falls at Trenton, or Trenton Falls, as is commonly known. It had less than a two-foot drop at the time it was measured by the NJGWS but has historical importance. The city of Trenton owes its existence to these “small falls”. A third exception is one of three falls at Little Falls in Essex County, which has a drop of approximately two feet when it was measured. Please note that the majority of these waterfalls are on public land, however a few are on private property. Please do not visit these sites without proper landowner permission.
