New Jersey Department of Environmental Protection, New Jersey Geological and Water SurveyThe "Brownfield and Contaminated Site Remediation Act" (N.J.S.A. 58:10B-1 et seq.) requires the Department of Environmental Protection to map regions of the state where large areas of historic fill exist and make this information available to the public. This GIS layer depicts areas of historic fill covering more than approximately 5 acres. For the purposes of this layer, historic fill, as defined at N.J.A.C. 7:26E-1.8, means, "non-indigenous material, deposited to raise the topographic elevation of the site, which was contaminated prior to emplacement, and is in no way connected with the operations at the location of emplacement and which includes, without limitation, construction debris, dredge spoils, incinerator residue, demolition debris, fly ash, or nonhazardous solid waste. Historic fill material does not include any material that is substantially chromate chemical production waste or any other chemical production waste or waste from processing of metal or mineral ores, residues, slag or tailings. In addition, historic fill material does not include a municipal solid waste landfill site." The information in the layer makes no determination whether the material was contaminated prior to emplacement. This layer can be used as one line of evidence for an investigator's professional judgment in determining that historic fill is present at a site; however, an investigation must still be completed in accordance with the Technical Requirements for Site Remediation at N.J.A.C. 7:26E-4.7. Also see the Historic Fill Technical Guidance for more information regarding the investigation and remediation of historic fill at: https://dep.nj.gov/srp/guidance/. This data was mapped at a scale of 1:24,000 (1 inch represents 2000 feet) and is not intended for use at more-detailed scales. Fill was mapped from stereo aerial photography taken in March 1979, supplemented in places by planimetric aerial photography taken in the spring of 1991 and 1992. Additional areas of fill were mapped by comparing areas of swamp, marsh, and floodplain shown on archival topographic and geologic maps on file at the N. J. Geological Survey, dated between 1840 and 1910, to their modern extent. In a few places, fill was mapped from field observations and from drillers' logs of wells and borings. Most urban and suburban areas are underlain by a discontinuous layer of excavated indigenous soil mixed with varying amounts of non-indigenous material. This material generally does not meet the definition of historic fill and is not depicted on this map. Also, there may be historic fills that are not detectable on aerial photography or by archival map interpretation and so are not shown on this map, particularly along streams in urban and suburban areas. As of this January 2016 edition, twelve new quadrangles were added to the statewide coverage. They are Allentown, Beverly-Frankford, Brookville, Canton-Taylors Bridge, Chatsworth, Forked River- Barnegat Light, Indian Mills, Keswick Grove, Lambertville, Millville, and Woodmansie. As of this March 2025 edition, eight new quadrangles were added to the statewide coverage. They were Cassville, Lakehurst, Oswego Lake, Jenkins, Atsion, Bridgeton, Whiting, and Lakewood. Seven quadrangles have been revised. They are Trenton East, Trenton West, Pennington, Lambertville, Rocky Hill, Ship Bottom, Point Pleasant, and Califon.ArcGIS DynamicMapLayerhttps://hub.arcgis.com/datasets/3fb0f185db114e26abd05dcff79760d7_22engNew Jersey Department of Environmental Protection's (NJDEP) Bureau of GISPublicHistorically Filled Areas in New Jersey [New Jersey]Web servicesNew JerseyLast Modified: 2025-04-16
