Ambient - Major Ions:
Ground-water quality data from the Ambient Ground Water Quality Monitoring
Network was and is being collected to increase our understanding of quality
versus the geologic makeup of various aquifers and quality versus non-point
source impacts from land use. This data set was established to allow all
interested parties easy access the network data in a visual format. The network
is being set up over a 5-year period which started in fiscal year 1999. Each
year, network wells are installed, and a small percent selected from existing
wells, and sampled. Well water samples for this layer were analyzed for Field
parameters (like Water Temperature, Specific Conductance, and others) and Major
ions (like Sodium, Potassium, and others).
A negative number (ex. -2) implies less than (ex. <2) reporting limit; The
reporting limit is 2 times the detection limit. Some of the detection limits
for a particular constituent varied with the method accuracy. -99999 implies an
estimated value; usually means the constituent was detected below the reporting
limit and the confidence in the concentration determination is not acceptable
for standard reporting. A zero (0) imples no sampling performed for that

AMNET Biological Monitoring Sites:
This data represents point sites sampled by NJDEP as part of its Ambient Biomonitoring Network (AMNET).
Sites are sampled in every Watershed Management Area (WMA) in the State. Historically, the New Jersey Impairment Score (NJIS), based on family level
taxonomy, was used for the entire state to make assessments at three levels of impairment; non-impaired, moderately impaired, and severely impaired.
Indices were developed, based on genus level taxonomy and grouped into three distinct geographical regions: high gradient (above the Fall Line), low
gradient (Coastal Plain excluding the Pinelands), and Pinelands (the boundary of the Pinelands National Reserve plus a 5-km buffer). These indices are
called High Gradient Macroinvertebrate Index (HGMI), Coastal Plain Macroinvertebrate Index (CPMI), and the Pinelands Macroinvertebrate Index (PMI).
These indices replace the NJIS and offer a greater level of resolution using four levels of assessment; excellent, good, fair, and poor. Round 1 data
has been assessed using NJIS, while all subsequent rounds are assessed using the HGMI, CPMI, or PMI.

Canals and Water
Raceways: New Jersey's canals and water raceways have been
important for transportation and water power for the last 300 years. They have
played a significant role in the economic development of the state. This data
shows locations of current and historic canals and raceways. Where possible,
these have been mapped based on site visits or current aerial photographs. The
location of some abandoned and filled canals and raceways are approximated from
historic maps and photographs and are not guaranteed to be accurate. Some of
the mapped canals and raceways are located on private property with no public
access. Other canals and raceways allow public access on the canal itself or
neighboring pathways, for recreational purposes. The user of this product is
responsible for determining if a canal or raceway is open to the public before
visiting. This data does not include dewatering canals and ditches with two
exceptions, the Berry's Creek Canal and the Old Canal. They were included in
this data because they are navigable. Channelized streams and underground
aqueducts are not included in this data.

CHANJ (Separated Layers): The CHANJ project represents a strategic plan for wildlife conservation that delineates and provides a common vision for a connected statewide landscape that, if protected and appropriately managed, will restore and maintain gene flow between viable breeding populations of terrestrial, native wildlife species, helping to ensure their long-term viability in New Jersey. CHANJ not only delineates a connected landscape, but also provides recommendations and resources for the actions needed to preserve and restore habitat connectivity for terrestrial wildlife in New Jersey. This initiative is designed to help 1) prioritize land protection, 2) inform habitat restoration and management, and 3) guide mitigation of barrier impacts on wildlife and habitats. We formed a multi-partner, multi-disciplinary working group to inform the development of this project that will help target local, regional, and state planning efforts and ultimately reconnect the landscape in New Jersey. The CHANJ products are intended to allow land-use, conservation, and transportation planners to operate in a more collaborative way, leveraging New Jersey's open space investment, increasing road safety, increasing permit efficiency, and ultimately improving the prospects for the long-term sustainability of New Jersey's terrestrial wildlife.

CHANJ Stepping Stones:
Animals need to be able to move through the landscape to find food, mates, and other resources. Without that ability to move, long-term viability of populations is in jeopardy. New Jersey is facing increasing habitat loss and fragmentation from steady urbanization, a dense network of roads, and a changing climate that are compromising the connectivity of habitat and resiliency of wildlife populations. Connecting Habitat Across New Jersey (CHANJ) represents a statewide habitat connectivity plan, developed in collaboration with a multi-partner, multi-disciplinary working group representing over 40 different agencies across the state, convened by the ENSP to address the importance of landscape permeability for the persistence of native terrestrial wildlife species. CHANJ mapping identifies core terrestrial wildlife habitat and corridors connecting them across the state, as well as intersecting road segments that serve as road barrier mitigation opportunities. The mapping is based on a naturalness index approach, and utilized core and corridor delineation GIS toolsets, Core Mapper and Linkage Mapper (www.circuitscape.org). Terrestrial species location data were used to inform model parameters and for validation. The Stepping Stones mapping was developed using the same methodology used to develop the CHANJ Cores, but with a smaller minimum threshold area size and are meant to help with connectivity planning by identifying areas within CHANJ Corridors that are more intact than others and may "live in" habitat for smaller, less vagile terrestrial wildlife species. The mapping was developed using raster data (10m grid cell size), and then converted to polygons for the final product.

Child Care Centers:
This data is a graphical representation of the listing of licensed active child
care centers in NJ. It was created for the State of New Jersey's initiative
regarding child care centers near contaminated sites. Non-profit child care
centers found in Public Schools (NIPS) are not included in this GIS layer
because they are not required to submit environmental data to the NJDEP for
NJDCF licensing. These centers may possibly be found on a public school GIS
layer (Please see Cross Reference Information for access to this data). Also,
proposed child care centers are not listed until a NJDCF License number is
issued. The table was pruned to include only active centers amounting at the
time of initial generation to 3,391 licensed centers. In addition 873 NIPS were
excluded.ADVISORY: This data was created only to be used as guidance to find
active child care centers. The data should not be used as the determining
factor in conducting receptor evaluations and the actions taken to protect
them. The child care data is updated continually and users are hereby notified
that data on NJDEP mapping applications for this data set may be more current

Chromate Waste Site Boundaries:
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.

Critical
Environmental and Historic Sites: This data contains the
boundaries of Critical Environmental and Historic Sites of the NJ State
Development and Redevelopment Plan (NJSDRP). These sites, submitted by county
and local entities, are areas generally less than one square mile which include
one or more environmentally or historically sensitive features. These sites are
recognized by the State Planning Commission. Critical Environmental Sites (CES)
and Historic and Cultural Sites (HCS) designations are used to help organize
planning for new development or redevelopment by singling out the elements of
natural systems, small areas of habitat, historic sites, and other features
that should continue to be expressed in the future landscape through protection
and restoration. The presence of CES and HCS gives land owners and developers
important advance information on how to shape their proposals for development
of the land around them, focusing on including them within the design and
function of the development whenever possible, while protecting them from
adverse impacts. Designating a site as a CES or an HCS means that the site is
of local, regional or statewide significance and that its protection and
enhancement is of primary importance.

Deed Notice Areas:
This data layer identifies those Known Contaminates Sites (KCS) or sites
on Site Remediations Programs' (SRP) Comprehensive Site List (CSL) that have
been assigned a Deed notice. Deed Notices are institutional controls in
geographically defined areas within which soil remedial cleanup guidelines for
specific contaminants have been exceeded. A deed notice is described by NJ
State Legislature (NJSA 58:10B-13a) as a "...notice to inform prospective
holders of an interest in the property that contamination exists on the
property at a level that may statutorily restrict certain uses of, or access
to, all or part of that property, a delineation of those restrictions, a
description of all specific engineering or institutional controls at the
property that exist and that shall be maintained in order to prevent exposure
to contaminants remaining on the property, and the written consent to the
notice by the owner of the property". The deed notice (polygon) was developed
to provide information regarding the spatial extent of soil contamination, as
well as information regarding engineering controls (eg. cap or fence) and
contamination found in the soils above the appropriate standard. This is aimed
to help preserve adequate protection of these contaminated soil regions and
helps to minimize any chance of exposure.

Designated Centers of the NJ State Development and Redevelopment Plan:
This dataset contains the boundaries of Designated and Proposed Centers of the NJ State Development and Redevelopment Plan (NJSDRP). Centers are the NJSDRP's preferred vehicle for accommodating growth. A Center's compact form is considerably more efficient than sprawl, providing opportunities for cost savings across a wide range of factors. Compact form also translates into significant land savings. A Center's development form and structure, designed to accommodate diversity, is also more flexible than single-use, single-purpose sprawl, allowing Centers to evolve and adapt over time, in response to changing conditions and markets. Centers promote community, protect the environment, provide enhanced cultural and aesthetic experiences, and offer residents a superior quality of life.Designated Centers are those that have been approved by the NJ State Planning Commission, while Proposed Centers are preliminary in nature and usually change upon Designation. Center locations were determined through a process called "Cross-acceptance," in coordination with other state, county and local entities. Refer to the NJSDRP for further description of the geographic nature of Centers.

data layer that is a subset of the USGS 1:24,000 high-resolution National
Hydrography Dataset (NHD). In Version 3.1 of the Landscape Project, stream and
water body centerlines from the NHD Streams 2002 data layer are used to
represent freshwater mussel habitat. Water body centerline and stream
centerline data are valued exclusively by freshwater mussel species occurrence
areas while other aquatic species habitats are represented with polygons from
the Species-Based Habitat layer. In order to form representative 'patches' of
habitat from the NHD Streams 2002 layer, centerlines were broken at the
following points:
The confluence of two or more streams The inflow/outflow of a water body
Stretches of stream intersected by a mussel SOA are valued as habitat.
All valued streams are buffered by 0.75 kilometers upstream and downstream. The
0.75 kilometer distance is chosen as a conservative buffer estimate because
scientific literature, which is based largely upon larval transport by host
fishes, indicates that if there are two occurrences within two kilometers of
each other (assuming unsuitable habitat between), these occurrences should be
considered as part of the same local population (NatureServe 2011). In the
cases where stream buffers of separate occurrences of the same species met,
either upstream or downstream, the stream segments between those occurrences
are also valued for that species. In addition, in cases where dams are barriers
the extent of stream valued was limited.

Gas Stations:
Gas Service Stations are points representing the locations of gasoline services
stations regulated by NJDEP. The NJDEP New Jersey Environmental Management
System (NJEMS) serves as the database that supplies coordinates and descriptive
attributes from several tables used to generate this GIS layer. This layer is
produced primarily for the NJDEP i-MapNJ ArcIMS interactive mapping web
application and ArcGIS (ArcView, ArcInfo) users. Program interests included in
NJEMS are: Air, Communications Center, Discharge Prevention, Exams and
Licensing, Fish Game and Wildlife, Green Acres, Hazardous Waste, Lab
Certification, Land Use, Landscape Irrigation, Parks and Forestry, Pesticides,
Pinelands, Planning, Radiation, Right-to-Know, Site Remediation, Soil
Conservation, Solid Waste, TCPA, Water Quality, Water Supply, and Watershed
Management. The locations derived using GPS represent main entrance or front
door locations for the sites. Users should note that not every site in NJEMS
presently (as of August 2006) has an established coordinate (GPS or otherwise).
NJDEP is continually working to acquire these with GPS, location data submitted
to permitting programs, and through address matching techniques.

Groundwater
Contamination Areas (CEA):
This data layer identifies those
Known Contaminated Sites or sites on the Site Remediation Program (SRP)
Comprehensive Site List where groundwater contamination has been identified
and, where appropriate, the NJDEP has established a Classification Exception
Area (CEA). CEAs are institutional controls in geographically defined areas
within which the New Jersey Ground Water Quality Standards (NJGWQS) for
specific contaminants have been exceeded. When a CEA is designated for an area,
the constituent standards and designated aquifer uses are suspended for the
term of the CEA.

Groundwater
Contamination Areas(CKE): This data layer contains
information about areas in the state which are specified as the Currently Known
Extent (CKE) of ground water pollution. CKE areas are geographically defined
areas within which the local ground water resources are known to be compromised
because the water quality exceeds drinking water and ground water quality
standards for specific contaminants. Historically, a number of the CKEs have
also been identified as Well Restriction Areas (WRAs). The regulatory authority
for developing CKEs is in N.J.A.C. 7:1J, entitled Processing of Damage Claims
Pursuant to the Spill Compensation and Control Act. CKEs are used by NJDEP
staff, water purveyors, and local officials to make decisions concerning
appropriate treatment and/or replacement of contaminated drinking water
supplies.

Highlands Boundary: The purpose of this dataset
is to provide an accurate depiction of the Highlands Preservation and Planning Area Boundaries as defined
by the act to use for planning purposes and for the implementation of the Highlands Regional Master Plan.
This dataset was developed to correspond to language in the codefied version of the NJ Highlands Water Protection
and Planning Act (P.L. 2004, Chapter 120) and in support of the 2008 Regional Master Plan.The entire area of the
Highlands Region in New Jersey is divided between the Highlands Preservation Area, in which development is more
strictly regulated, and the Highlands Planning Area. Any major development project proposed in the Preservation
Area must undergo extensive reviews specific to the Highlands, but the NJDEP Division of Land Use Regulation.
Development activities in the Planning Area are governed by existing NJ land use regulations and by the Highlands regional master plan. For more

Historic
Archaeological Site Grid:
This dataset includes a vector
grid of approximately 1/2 mile cells indicating the presence of archaeological
sites that:
1. Are included in the New Jersey or National Registers of Historic Places,
2. Have been determined Eligible for inclusion through federal or state
processes as administered by the New Jersey Historic Preservation Office (HPO),
or
3. Have been identified through cultural resources survey conducted pursuant to
federal or state processes as administered by the New Jersey Historic

Historic Fill:
The
"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 map shows areas of historic fill covering more than
approximately 5 acres. For the purposes of this map, historic fill is
non-indigenous material placed on a site in order to raise the topographic
elevation of the site. No representation is made as to the composition of the
fill or presence of contamination in the fill. Some areas mapped as fill may
contain chemical-production waste or ore-processing waste that exclude them
from the legislative definition of historic fill. 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.

Historical Maps:
This Open Geospatial Consortium (OGC) compliant Web Map Service (WMS) includes
a mosaic of historical USGS topographic maps of New Jersey surveyed from 1881
to 1924. The WMS is georeferenced to Geographic WGS84. The mosaic was produced
by scanning 15 minute (1:62,500 scale) historical USGS topographic paper maps
at 600 dpi and saving them as Tagged Image File Format (TIFF) images. The
scanned TIFFs have an approximate pixel resolution of 17 feet. The Milford 1913
and Bushkill 1924 map images were obtained from the USGS Delaware Basin Project
website (http://mcmcweb.er.usgs.gov/de_river_basin/de_water_gap/data_list.html)
because they were missing from the original historical map set. They were added
to the mosaic to provide full coverage of New Jersey. A "fishnet" of 15 minute
tiles was created to georeference the map images. The fishnet was created in
the maps' native coordinate system, Clarke 1866, and re-projected to New Jersey
State Plane feet NAD83. The TIFFs were then georeferenced to the tiles and
clipped to remove the collars (border areas of the maps). The TIFFs were
converted to JPEG2000 files to be used in the mosaic for the WMS. The spatial
reference of the WMS is Geographic WGS84.This product is to be used for
reference purposes only. The original historical paper maps were distorted or
damaged to varying degrees due to age and use. During visual testing, it
appeared that spatial inaccuracies in the images exceed 200 feet in several
locations. The digital product has not been corrected for distortion nor
vertical displacement. Consequently, this product does not meet the National
Standard for Spatial Data Accuracy (NSSDA).

Impervious
Surface % (2007):
The Impervious Surface layer is taken from
the Land Use 2007 data set. What is meant by impervious surface is material
such as concrete and asphalt that comprise roadways, parking areas, sidewalks
and buildings. As the land use/land cover of each polygon was mapped from 2007
aerial photography, a visual estimate was also made of the amount of impervious
surface in each. This estimate was recorded as a percentage of the total
polygon area, in 5% increments, which are depicted here. These percentages can
be used to determine the total acreage of impervious surface in any area of
interest. The 2007 LU/LC data set is the fourth in a series of land use mapping
efforts that was begun in 1986. Revisions and additions to the initial baseline
layer were done in subsequent years from imagery captured in 1995/97, 2002 and
2007. This present 2007 update was created by comparing the 2002 LU/LC layer
from NJ DEP's Geographical Information Systems (GIS) database to 2007 color
infrared (CIR) imagery and delineating and coding areas of change. Work for
this data set was done by Aerial Information Systems, Inc., Redlands, CA, under
direction of the New Jersey Department of Environmental Protection (NJDEP),
Bureau of Geographic Information System (BGIS). LU/LC changes were captured by
adding new line work and attribute data for the 2007 land use directly to the
base data layer. All 2002 LU/LC polygons and attribute fields remain in this
data set, so change analysis for the period 2002-2007 can be undertaken from
this one layer. The classification system used was a modified Anderson et al.,
classification system. An impervious surface (IS) code was also assigned to
each LU/LC polygon based on the percentage of impervious surface within each
polygon as of 2007. Minimum mapping unit (MMU) is 1 acre.

Known Contaminated Sites List:
The Known Contaminated Sites List (KCSNJ) for
New Jersey are those sites and properties within the state where contamination of soil or ground water
has been confirmed at levels equal to or greater than applicable standards. This list of Known Contaminated
Sites may include sites where remediation is either currently under way, required but not yet initiated or has
been completed. The KCSLNJ layer has now been modified such that the information portrayed in the GIS layer is
updated on a daily basis through a SQL query of NJEMS/Masterfile. Generating the KCSL GIS layer on a daily basis
via an SQL query allows for a dynamic KCSL layer. This is critical for the general public and SRP regulated community

Landscape Regions:
New Jersey's dunes, beaches, tidal marshes, cedar swamps, vast pitch pine
forests, extensive grasslands, peat bogs, maple-oak forests, ridgetops,
brackish bays, rivers, streams and the Atlantic Ocean support an amazing array
of wildlife. That is true despite the fact that much of its diverse landscape
has been greatly altered by human enterprises such as agriculture and
development that fragments and degrades wildlife habitat. Sustaining wildlife
populations over time requires large healthy landscapes with broad expanses of
natural habitat. Thus, the Landscape Project focuses on ecoregions or Landscape
Regions where plant and animal communities are ecologically similar and closely
interlinked. The delineation of the state into regions serves as a spatial
framework for management and conservation of species and their habitats, and as
a means to organize information so that it is meaningful and widely accessible
to end-users. Geographic features and landforms (e.g., rivers, watershed
boundaries, ridgelines, soils, vegetation, etc.) were used to delineate the
general area of five Landscape Regions in New Jersey. Region boundaries were
shifted to align with major roads (county level or larger) that serve as
barriers to movement for many species. A sixth region, the Marine Region, is an
exclusively aquatic region that includes the New Jersey portion of the Delaware
and Raritan bays as well as the portion of the Atlantic Ocean along the coast
of New Jersey. ENSP has identified and mapped habitat for endangered,
threatened and special concern wildlife within each Landscape Region utilizing
an extensive database that combines species occurrence information with
land-use/land-cover classification data and species habitat requirements. The
resulting Landscape maps provide an accurate, reliable and scientifically sound
basis for habitat protection within each region. One of the Landscape Project's
unique features is that it enables users to focus on the big picture, and not
just on individual locations of imperiled and special concern species as those
areas become threatened. Thus, within large landscapes, the Landscape Project
identifies areas of endangered and threatened wildlife habitat that are
important to the maintenance and recovery of New Jersey's endangered and
threatened wildlife populations.

Landslides: Landslides in
New Jersey contains point locations and other attributes for historic and
recent landslide locations in New Jersey mapped by the New Jersey Geological
Survey (NJGS). The landslides have occurred in the northern and central part of
the state and include slumps, debris flows, rockfalls and rockslides. Although
in New Jersey landslides are not as common as in other areas of the United
States, they are a geologic hazard in areas with steep to moderate slopes or
geologic units prone to failure. They cause damage to utilities, property, and
transportation routes. The average annual direct and indirect cost of New
Jersey landslides is likely in the hundreds of thousands of dollars. New Jersey
landslides have also caused fatalities and injuries.

NAACC Culvert Inventory of New Jersey - Aquatic Organism Passability:
The North Atlantic Aquatic Connectivity (NAACC) is a network of individuals from universities, conservation organizations, and state and federal natural resource and transportation departments focused on improving aquatic and terrestrial connectivity across a thirteen-state region, from Maine to Virginia. NJ is one of the 13 states in the region participating in the North Atlantic Aquatic Connectivity Collaborative (NAACC), the goal of which is to develop additional common protocols and training for assessing road-stream crossings and also houses the field data, collected using existing protocols, in a regional database. Bridge spans, and medium and large culverts with certain features are known to be utilized by many aquatic and terrestrial wildlife species to cross beneath roadways. The NAACC Culvert Assessment Protocol involves collecting a variety of data associated with culverts and bridges, including, but not limited to, structure dimensions, the presence of dry, and physical barriers. This dataset reflects the New Jersey portion of the NAACC database. The full database is already available publicly: https://www.streamcontinuity.org/cdb2/naacc_search_crossing.cfm.

The goal of the NAACC collaborative, is to develop common protocols and training for assessing road-stream crossings across the thirteen-state region, and to house the field data collecting using those protocols, in a regional database that is accessible to the public. The purpose for creating a filtered New Jersey version of the database, which is linked to the larger regional database, is to make it as accessible to interested parties in New Jersey. Specifically, the road-stream crossing assessments have tremendous utility as a component of the Division of Fish and Wildlife's Connecting Habitat Across New Jersey (CHANJ, www.CHANJ.nj.gov) project. When the completed road-stream assessments are integrated with the CHANJ mapping, they can help identify opportunities to improve safe passage for wildlife in areas that occur within mapped wildlife habitat cores and corridors. Therefore, we want to make the NAACC database as accessible to CHANJ partners and potential partners as possible.

Natural Heritage Grid Map:
Through its Natural Heritage Database, the Office of Natural Lands
Management (ONLM) documents rare species and ecological community habitat to
inform decision-makers who need to address the conservation of natural
resources. The Natural Heritage Grid Map is a geographic information system
(GIS) file that provides a general portrayal of the geographic locations of
rare plant species and ecological communities for the entire state. It does not
contain data for animal species. The Natural Heritage Grid Map was produced
using computer-generated vector-based polygons that divide the boundary lines
of each USGS 1:24,000 scale topographic map into 100 grid cells, each cell
being between 358 and 372 acres in size. If a rare plant species or ecological
community has been documented from anywhere within a cell, the entire cell will
be coded as containing an occurrence of a rare plant species/ecological
community. An associated data table can be linked or related to the NHPGRID
table in order to display information about the individual rare plant
species/ecological community occurrences within any cell.

Natural Heritage
Priority Sites:
The Natural Heritage Priority Sites Coverage
was created to identify the best habitats for rare plant and animal species and
natural communities through analysis of information in the NJ Natural Heritage
Database. Natural Heritage Priority Sites contain some of the best and most
viable occurrences of endangered and threatened species and natural
communities, but they do not cover all known habitat for endangered and
threatened species in New Jersey. If information is needed on whether or not
endangered or threatened species have been documented from a particular piece
of land, a Natural Heritage Database search can be requested by contacting the
Office of Natural Lands Management.

NJEMS Sites:
NJEMS Sites are points representing sites regulated by NJDEP under one or more
regulatory permitting or enforcement programs, or sites that are otherwise of
some interest to a NJDEP program. The NJDEP New Jersey Environmental Management
System (NJEMS) serves as the database that supplies coordinates and descriptive
attributes from several tables used to generate this GIS layer. This layer is
produced primarily for the NJDEP i-MapNJ ArcIMS interactive mapping web
application and ArcGIS (ArcView, ArcInfo) users.
Program interests included in NJEMS are: Air, Communications Center, Discharge
Prevention, Exams and Licensing, Fish Game and Wildlife, Green Acres, Hazardous
Waste, Lab Certification, Land Use, Landscape Irrigation, Parks and Forestry,
Pesticides, Pinelands, Planning, Radiation, Right-to-Know, Site Remediation,
Soil Conservation, Solid Waste, TCPA, Water Quality, Water Supply, and
Watershed Management. The locations derived using GPS represent main entrance
or front door locations for the sites. Users should note that not every site in
NJEMS presently (as of September 2004) has an established coordinate (GPS or
otherwise). NJDEP is continually working to acquire these with GPS, location
data submitted to permitting programs, and through address matching techniques.

NJPDES Combined Sewer Overflow (CSO):
This is a geographical representation of the locations of CSO outfall points statewide. Combined Sewer Overflows (CSO)
are sewers that are designed to collect rainwater runoff, domestic sewage, and industrial wastewater in the same pipe. Most of the time, combined sewer systems
transport all of their wastewater to a sewage treatment plant, where it is treated and then discharged to a water body. During periods of heavy rainfall or snowmelt,
however, the wastewater volume in a combined sewer system can exceed the capacity of the sewer collection system or treatment plant.This map data layer provides information regarding the location of permitted CSO Outfall Points, the applicable NJPDES Permit number, the assigned 3-digit discharge serial number, the latitude and longitude,
the alternate name (such as a street address) of the CSO point, the municipality and Watershed Management Area (WMA) where the CSO outfall is located, a unique identifier for
each point consisting of the permit number and outfall number, the receiving waterbody, the receiving treatment plant name and permit number, if the CSO outfall has solids
and floatable treatment, a link for Discharge Monitoring Report (DMR) data, and a website.

NJPDES Regulated Facility Locations:
The NJPDES layer shows approximate locations of permitted facilities regulated
by New Jersey Department of Environmental Protection's Bureau of Nonpoint
Pollution Control (BNPC). Permits vary based on discharge type and activity
governed by N.J.A.C. 7:14A. This layer includes seven different discharge
types, which the Department regulates. It includes facilities regulated for
having a discharge of sanitary sewage to the ground with a design volume in
excess of 2,000 gallons per day (GPD), but which were constructed prior to
January 1, 1990 and approved by local Health Departments. It includes concrete
product manufactures that have stormwater discharges to surface waters. These
facilities manufacture concrete products, concrete block and brick, and ready
mixed concrete or are facilities classified as concrete manufacturers by the
New Jersey Department of Environmental Protection (NJDEP). It includes
permitted facilities for having sanitary wastewater and industrial wastewater
discharges though various methods such as lagoons, spray irrigation, or
overland flow. It includes industrial wastewater facilities, such as cooling
water, process wastewater, and boiler blowdown and facilities with subsurface
disposal system(s) that discharges greater than 2,000 GPD to septic systems,
subsurface trench systems, dry wells, or seepage pits. It includes facilities
that engage in the activity of manufacturing hot mix asphalt and that discharge
stormwater to either the surface or ground water sources. It includes
facilities that cannot eliminate exposure of pollutants to stormwater and it
includes facilities involved in the recycling of materials including metal
scrap yards, battery reclaimers, salvage yards, and automobile junkyards.
NJPDES permits are issued by the NJDEP and are authorized according to a
specific set of rules governing discharges within the state of New Jersey.

Nodes:
This dataset contains the boundaries of Nodes of the NJ State Development and Redevelopment Plan (NJSDRP). A Node is an existing or planned concentration of facilities and activities which are not organized in a compact form. Types of nodes include Commercial-Manufacturing nodes and Heavy Industry-Transportation-Utility nodes. An Existing Node is a concentration of facilities and activities that are not organized in a compact form and are encouraged to be retrofitted over time to reduce automobile dependency, diversify land uses, and enhance linkages to communities. A new Node may identify new heavy industry, transportation or utility facilities and activities as part of Plan Endorsement. A new Node should be organized in a compact form and located in Centers and other appropriate areas in Metropolitan or Suburban Planning Areas or Centers in Fringe, Rural or Environmentally Sensitive Planning Areas. Refer to the NJSDRP for further description of the geographic nature of Nodes.

Open Space:
This New Jersey Open Space and Preservation Resources Inventory (OSPRI) dataset contains Green Acres encumbered
and unencumbered protected open space and recreation areas. The Green Acres encumbered lands are owned in fee
simple interest by either the state, county, municipality, or a nonprofit agency and have either received funding
through the Green Acres State or Local Assistance Program or are listed on a Green Acres approved Recreation and
Open Space Inventory (ROSI). The unencumbered open space lands do not fall under Green Acres rules and regulations
and therefore have a lesser level of protection. Types of open space property in this data layer include parks,
conservation areas, preserves, historic sites, recreational fields, beaches, etc. The data was derived from a variety
of mapped sources which vary in scale and level of accuracy. These sources are inclusive of but not exclusive of tax
maps, surveys, deeds, digital aerial photography, as well as USGS topographic maps.

Parcels Data(Block and Lot):
This spatial layer is a composite of tax parcel polygons, edgematched across most municipal boundaries.
It serves as one of the statewide framework GIS data sets for New Jersey. It is compatible with the
New Jersey Department of the Treasury MOD-IV system currently used by Tax Assessors.The composite is
created from component data sets from counties and the City of Newark. Stewardship and maintenance of
the data will continue to be the purview of county and municipal governments, but the statewide composite
will be maintained by the NJ Office of Information Technology (NJOIT), Office of Geographic Information
Systems (OGIS).Please note that these parcel data sets are not intended for use as tax maps. They are
intended to provide reasonable representations of parcel boundaries for planning and other purposes.

Physiographic
Provinces:
New Jersey is divided into the Valley and Ridge,
Highlands, Piedmont, and Coastal Plain Physiographic Provinces. Each province
defines a region in which relief, landforms, and geology are significantly
different from that of the adjoining and nearby regions. The boundary between
each province is determined by a major change in topography and geology, and
this data set delineates the boundary lines between them.

Place Names:
This point
layer was extracted from a data set produced by the United States Geological
Survey (USGS), as part of its topographic map data base. Topographic maps,
known as topoquads, are USGS maps that show a wide variety of information
including generalized land use, roads and railroads, streams, political
boundaries and the locations of many kinds of named features, among other
things. For this application, a subset of two types of USGS point features,
Places and Locales, were selected for display. Since many of these named
locations are locally familiar names, they can serve to orient the user to the
map display. For more information of the USGS data set, go to

Purveyor:
This is a graphical
representation of the 1998 Public Community Water Purveyor Service Areas. Water
purveyors are regulated by the NJDEP Bureau of Safe Drinking Water, under the
Safe Drinking Water Act. Public Community Water Purveyors are systems that pipe
water for human consumption to at least 15 service connections used year-round,
or one that regularly serves at least 25 year-round residents. Public purveyors
can be government agencies, private companies, or quasi-government groups. The
boundaries mapped are those of the actual water delivery or service area.
Franchise areas are not depicted (areas with legal rights for future service
once developed). Water sources (wells or surface water intakes) are often

Railroads Network:
New Jersey involves both freight and passenger travel, for local and long distance travel. NJDOT focuses on freight rail transportation and coordinates with the Class 1s, Regional and Short Line railroads. The Department coordinates with NJTRANSIT for the provision of statewide transportation and passenger rail service. The New Jersey Department of Transportation (NJDOT) has a vital interest in preserving and improving the rail freight part of its transportation network. New Jersey has approximately 1,000 miles of rail freight lines serving customers large and small. Our state is served by short line regional and national railroads. Rail shipments allow cost effective movement of goods with less stress on the State's highway system as well as fewer emissions and less energy use. NJDOT supports New Jersey's economic activity by providing a strong, multimodal transportation system that makes rail service available, safe and effective for as many businesses as possible.

SBH - Atlantic Coastal - Landscape Project: The
Landscape Project combines documented wildlife locations with NJDEP aerial
photo-based 2007 Land Use/Land Cover (LULC) to delineate imperiled and special
concern species habitat within New Jersey. Many species occurrence locations
cannot be published because they may represent nest sites, roost sites, dens
and other sites used by species that are vulnerable to human disturbance and,
in some cases, susceptible to illegal collection. At the same time, wildlife
moves, as individual animals use various habitat features within the landscape
to fulfill their foraging, sheltering and breeding needs. Therefore, protecting
individual occurrences or the area used by one individual is generally not
sufficient to protect the local population. Landscape Project maps address
these issues by displaying habitat patches that animals use and that are
required to support local populations, rather than pinpointing exact locations
of the most sensitive wildlife sites or simply protecting points where species
happened to be observed at one point in time. Prior to combining species
occurrence data with LULC data to form the habitat patches that make up the
Species-Based Habitat layer, each dataset was generated according to a specific

Schools: This feature class
and shapefile consist of point locations of schools in New Jersey. School
records were derived from the public school, non-public school, and district
tables published by the New Jersey Department of Education; the records were
address-matched and in most cases checked against orthophotography.Most of the
records were processed in 2003. For public schools, approximately 100
additional records were processed in 2007, and 38 in 2008. The public school
data set includes records that appeared in the 2003 or 2007 data set but not in
the 2008 table, and are presumed to be closed schools (see CLOSED attribute).
Attribute and spatial location corrections were made in 2009 to selected
records (see process steps). The non-public school data have not been updated

for specific areas, i.e. whether the wastewater will be collected to a regional
treatment facility or treated on site and disposed of through a Surface Water
(SW) discharge or a groundwater (GW) discharge. Areas not specifically mapped
represent either water features where no construction will occur or land areas
that default to individual subsurface disposal systems discharging less than
2,000 gallons/day (gpd) where the site conditions and existing regulations
allow. This mapping, in conjunction with the text of the associated Water
Quality Management Plan (WQMP), is used to make consistency determinations
under the Water Quality Management (WQM) Planning rules, N.J.A.C. 7:15. The SSA
mapping is prepared under the Water Quality Management (WQM) Planning rules,

categories: Prohibited - harvest not allowed under any conditions. Special
Restricted - harvest allowed with a special permit requiring further
purification of the shellfish before sale. Seasonal (Nov - Apr) - and Seasonal
(Jan - Apr) - where harvest is permitted only during certain seasons of
the year. The final category is Approved - harvest permitted under any
conditions. Classification of the waters is based on the National Shellfish
Sanitation Program. As specified in this program, classifications are based on
three components: 1) Regular monitoring of water quality 2) Field surveys of
shoreline conditions 3) Study of water currents and flows (hydrography). These
functions are performed by New Jersey's Bureau of Marine Water Monitoring which
monitors about 2,500 locations a minimum of five times a year.

county soil maps throughout the United States under the Soil Survey Geographic
Database program (SSURGO). The intent of the program is to create new digital
soils maps for each county, which are spatially accurate and fully attributed. To
date, the USDA has completed and distributed new soil layers for 19 New Jersey
counties, with only Hudson and Warren Counties not available. There
will be no data set created for Hudson County, since there was no
original soil survey created for it. The soil layer for Warren County is
presently still under development. When completed, the Warren County data will
be added to this statewide SSURGO layer.
As part of the SSURGO mapping program, complete soil attribute information for
each county has also been put into digital format. Only a small amount of this
attribute information can be included in this application. If more soil
information is required, users can download a Microsoft Access database for
each county from the official USDA SSURGO site, (https://websoilsurvey.sc.egov.usda.gov/App/HomePage.htm).
The digital soil layers for each county are also available from this site in
several different formats and projections, although layers in New Jersey State
Plane Feet are not provided. However, the NJDEP has projected all of the
available counties to NJSPF, and posted the projected layers on the NJDEP
website (https://www.state.nj.us/dep/gis/soilsshp.html).

2002 and 2007. This present 2007 update was created by comparing the 2002 LU/LC layer from NJ DEP's Geographical Information Systems (GIS)
database to 2007 color infrared (CIR) imagery and delineating and coding areas of change. Work for this data set was done by Aerial
Information Systems, Inc., Redlands, CA, under direction of the New Jersey Department of Environmental Protection (NJDEP), Bureau of
Geographic Information System (BGIS). LU/LC changes were captured by adding new line work and attribute data for the 2007 land use
directly to the base data layer. All 2002 LU/LC polygons and attribute fields remain in this data set, so change analysis for the
period 2002-2007 can be undertaken from this one layer. The classification system used was a modified Anderson et al., classification
system. An impervious surface (IS) code was also assigned to each LU/LC polygon based on the percentage of impervious surface within
each polygon as of 2007. Minimum mapping unit (MMU) is 1 acre.ADVISORY:This metadata file contains information for the 2007Land Use/Land Cover (LU/LC)

Sole-Source Aquifers:
There are seven sole-source aquifers (SSAs) in New Jersey. These are
defined by the EPA as those aquifers that contribute more than 50% of the
drinking water to a specific area and the water would be impossible to replace
if the aquifer were contaminated. Sole-source aquifers are defined with
guidelines set forth by the U.S. Environmental Protection Agency (EPA) as
authorized in section 1424(e) of the Safe Drinking Water act of 1974. Any
federally-funded project in an area that could affect ground-water in a
sole-source aquifer must be reviewed by the US EPA. This 'project review area'
includes the aquifer's 'recharge zone' and it's 'stream-flow source zone'. The
recharge zone is the area through which water recharges the aquifer. The source
zone is the upstream area that contributes recharge water to the aquifer. The
EPA sometimes modifies the project review areas as published in the Federal
Register in order to better protect zone as originally published. Most of New
Jersey is covered by the seven SSAs and their project review areas. The order
of chronological approval is as follows: 1.) Buried Valley SSA 2.) Ridgewood
SSA 3.) Rockaway SSA 4.) Highlands SSA 5.) Northwest New Jersey SSA 6.) Coastal
Plain SSA 7.) Ramapo SSA The sole source aquifer program is a federal program
administered by the Environmental Protection Agency under the Safe Drinking
Water Act. All questions about the program should be addressed to them. EPA's
reference for the sole source aquifers in New Jersey is at:

State Plan Designated Centers:
This data layer was
generated as part of the New Jersey State Development and Redevelopment Plan.
Mapped are the boundaries of several categories of urban centers that are
identified as part of the state plan. Centers are defined as areas with compact
development, as opposed to areas that have less compacted, sprawl development.
Since centers have existing infrastructure, new development or redevelopment
should be directed to these areas. There are five types of centers in the state
plan: Urban Centers, Regional Centers, Towns, Villages and Hamlets. Both
already designated and planned centers are included. For more
information on the Centers and the state plan go to
https://nj.gov/state/planning/regional-coordination-centers-and-endorsed-plans.shtml.

State Planning Area Boundaries:
Depicted
is the State Plan Policy Map of the New Jersey State Development and
Redevelopment Plan. This plan establishes the groundwork for an
integrated, statewide approach to future land use planning. The ultimate goal
of the plan is to insure that both sustainable growth and natural resource
protection are part of New Jersey's future. To guide the development
strategies, the Office of State Planning has created the policy map to
identify and locate the different types of areas that the state plan utilizes.
Over twenty detailed area types are included in the policy map. These area
designations, in conjunction with additional data layers, such as the State
Planning Centers layer also included in this application, will be used
to guide planning policy decisions throughout the state. For more information
of the New Jersey State Plan, go to

Streams:
This layer depicts rivers, streams,
canals, and other drainage features of the state. It was originally developed
by the USGS for the topoquad mapping program. Both this layer, and a companion
layer, Water Bodies, will be updated in the future to reflect more
current conditions of the state's water features.

Sub-Watersheds (HUC14):
The watersheds shown in this layer are the smallest watersheds mapped by the
NJDEP and the USGS, with each covering only approximately 3,000 acres. The USGS
calls the watersheds Hydrologic Units. Each basic unit is a unique
feature, and is given a unique Hydrologic Unit Code (HUC), which is 14
digits long. The HUC is hierarchical. Larger and larger watersheds can be
defined using different portions of the 14 digit code to define the watershed
boundaries. These HUC14 watersheds form the basis for the other
watershed layers.

Surface Water Quality Classification:
This data is a digital representation of New Jersey's Surface Water Quality Standards in accordance with "Surface Water Quality Standards for New Jersey Waters" as designated in N.J.A.C. 7:9 B. The Surface Water Quality Standards (SWQS) establish the designated uses to be achieved and specify the water quality (criteria) necessary to protect the State's waters. Designated uses include potable water, propagation of fish and wildlife, recreation, agricultural and industrial supplies, and navigation. These are reflected in use classifications assigned to specific waters. The line-work has been broken/altered to reflect the descriptions specified at N.J.A.C. 7:9B-1.15. When interpreting the stream classifications and anti-degradation designations, the descriptions specified in the SWQS at N.J.A.C. 7:9B-1.15 always take precedence. The GIS layer reflects the stream classifications and anti-degradation designations adopted as of the publication date and is supplemental only and is not legally binding.

Surface Water Springs:
A spring is any natural discharge of water from rock or soil onto the surface of land. Specifically, springs are places where subsurface water comes to the surface from the ground and flows or where it lies in pools that are continually replenished from below. Thus, a spring is a site where the aquifer surface meets the ground surface. The water source for a spring can vary. Some springs are fed by shallow groundwater seepage out of the soil, while others are fed by deep aquifer water discharged under artesian pressure. These differences influence the hydrology and the water chemistry of springs. They range in size from intermittent seeps, which flow only after a great deal of rain, to huge spring pools with tens of thousands of gallons flowing daily. Springs may be permanent (perennial) and flow throughout the year, or ephemeral (intermittent or temporary) and flow only during or after rain. Where evaporation is high, the flow of springs can decrease or cease during the warm season. The amount of water that flows from springs depends on many factors including: the size of the caverns (or porosity) within the rocks, the water pressure in the aquifer, the size of the spring basin, and the amount of rainfall. Human activities can also influence the volume of water that discharges from a spring. Ground-water withdrawals in an area can reduce the pressure in an aquifer, causing water levels in the aquifer system to drop and ultimately decreasing the flow from the spring. In some cases, springs have completely disappeared over time due to water withdrawal from urbanization. It is thought that half of all the springs in the United States have dried up since settlement of the country began. New Jersey has many examples of springs which once flowed but do not exist anymore.

Surficial Aquifers:
The Surficial Aquifers of New Jersey consists of Geographic Information Systems
(GIS) coverage (shapefile) of surficial aquifers and confining units in New
Jersey. The surfical aquifer coverage includes glacial sediment exceeding 50
ft. thickness in northern New Jersey, and surficial sediment thicker than 50
ft. overlying Coastal Plain aquifers and confining units. The coverage is
generalized to the 1:250,000 scale by eliminating polygons with less than
1,000,000 sq. ft. area (about 23 acres). The data were digitized from various
published and unpublished 1:24,000, 1:100,000,and 1:250,000 scale geologic maps
compiled from 1987 to 1993.
back to top
Surficial Geology:
The Surficial Geology of New Jersey shows the extent of surficial geologic
materials in New Jersey. Surficial materials are the unconsolidated glacial,
river, wetland, windblown, marine, estuarine, and hillslope sediments and
weathered rock materials that overlie bedrock and Coastal Plain formations and
that are the parent material for agronomic soils.

Surficial Geology Cross Sections: The Surficial Geology Cross Section
Lines are cross sections that show the extent, thickness, and layering of
surficial materials in the subsurface along the line of section.

Tidelands Claim Lines:
The Tidelands claims line depicts areas now or formerly flowed at or below mean
high tide. Since the mean high water line may change because of rises in sea
level, the line does not represent the current mean high water line. Rather it
depicts the mean high water line at the time of mapping and the historic mean
high water line predating artificial alterations. The Tidelands claim line was
originally mapped and promulgated on 1628 individual maps produced at a scale
of 1:2400. The individual maps were subsequently merged together to produce the
tidelands region shapefiles presented here. These region files were created to
be used only as resource data sets to more easily identify those areas claimed
under the tidelands program. They are not to be considered the official
tidelands claim lines. Only the actual promulgated tidelands maps, at the
production scale of 1:2400, can be used to locate the legally valid tidelands
riparian claim line. For questions concerning possible tidelands claims,
contact the Bureau of Tidelands as indicated in the full metadata record.

TMDL (Lakesheds):
The pollutants of concern for these lake TMDLs are phosphorus and fecal coliform. Phosphorus is an essential nutrient for plants and algae,
but is considered a pollutant when it stimulates excessive plant and algae growth. Overgrown vegetation and algae blooms in lakes can prevent
recreational use for fishing and swimming. In severe cases, plant and algae die-off can deplete oxygen in the lake raising the potential for
killing fish in the lake. Potential sources of phosphorus include discharges from sewage treatment plants, combined sewer overflows and
stormwater runoff. As stormwater flows over the land, it may pick up phosphorus. Phosphorus contributions to stormwater runoff are calculated
based on land uses within the lake's watershed. Nonpoint and stormwater point sources are the primary contributors to fecal coliform loads and
can include storm-driven loads transporting fecal coliform form sources such as geese, farms, and domestic pets to the receiving water. Nonpoint
sources also include steady-inputs from sources such as failing sewage conveyance systems and failing or inappropriately located septic systems.
The TMDLs are derived from waste load allocations from point sources plus load allocations from non-point sources and a margin of safety to
account for uncertainty in the model.
back to top
TMDL (Shellfish):
The pollutant of concern for these shellfish TMDLs is total coliform. Nonpoint and stormwater point sources are the primary sources
of total coliform/fecal coliform loads in these waterbodies. Source loads were estimated for land uses in each watershed and for local
marinas that may be causing water quality impacts in these waterbodies. TMDLs were developed based on an analysis of the existing pathogen
indicator data compared to NSSP and NJDEP pathogen indicator criteria, and the loading capacity has been allocated among the point and
nonpoint sources. The TMDL reports include implementation strategies that will bring the subject waterbodies into compliance with the
NSSP criteria for unrestricted shellfish harvest.
back to top
TMDL (Streamsheds):
The pollutants of concern for these Stream TMDLs are fecal coliform and total phosphorus. Concentrations of these pollutants were found to exceed
New Jersey's Surface Water Quality Standards (SWQS), published at N.J.A.C. 7-9B et seq., for the segments identified in the Reports. In accordance
with Section 305(b) of the Federal Clean Water Act (CWA), the State of New Jersey developed the 2002, 2004 and 2006 Integrated List of Waterbodies,
addressing the overall water quality of the State's waters and identifying impaired waterbodies for which Total Maximum Daily Loads (TMDLs) may be
necessary. As reported in the 2002, 2004 and 2006 Integrated List of Waterbodies, also identified is the river miles and management response associated
with each listed segment. Nonpoint and stormwater point sources are the primary contributors to loads in these streams and can include storm-driven loads
transporting fecal coliform form sources such as geese, farms, and domestic pets to the receiving water. Nonpoint sources also include steady-inputs from
sources such as failing sewage conveyance systems and failing or inappropriately located septic systems. In some instances, point sources such as
publicly-owned treatment works can contribute to phosphorus loads, and therefore will have further restrictions on effluent limits. The TMDLs are
derived from waste load allocations from point sources plus load allocations from non-point sources and a margin of safety to account for uncertainty
in the model.

Topographic Images 24k Black and White:
This set of ARC/INFO grids and bit-mapped images is derived from 14 U.S.
Geological Survey 1:100,000- scale, 30 x 60 minute, digital raster graphic(DRG)
images covering the New Jersey region. The grids were produced to create a set
of three seamless and tiled images covering the north, central and southern
parts of New Jersey. The tiles coincide with the geographic extent of the three
sheets for the 1:000,000 scale Geologic Map of New Jersey, and are intended for
use as base maps within a Geographic Information System (GIS). The conversion
of the rasterized topographic-map images to a bit-mapped, monochromatic mode
results in the loss of some map information otherwise included on full-colored
topographic maps, such as area shading for wooded areas. The output images use
an uncompressed tagged-image-file format (TIFF) and preserve the 250
dots-per-inch resolution of the DRG source imagery. Each image was processed
to clear features outside tile neat lines and the State boundary. Some map
features were set to a background value prior to conversion to a monochromatic
image mode to enhance image clarity. The images are geo-registered and
rectified to the 1983 North American Datum in state plane coordinate feet.
Each image was geo-registered using at least three links including the corners
of each 30 x 60 minute sheet and 7-1/2' reference tics within New Jersey.
Purpose: To provide basemaps for overlaying digital data.

Original DRG'S supplied by the U.S. Geological Survey were reprocessed by removing the collar information and reprojecting into NAD83 NJ State Plane Feet. Each raster entity or pixel contains a color index from 0 through 12 referencing a color palette of RGB values from 0 through 255 in which the standard colors used in the DRG are defined.
In most client software, the default spatial reference system of the service will be Geographic Coordinates, WGS84. Several other coordinate systems are supported natively by the WMS (see Supplemental Information).

Underground
Storage Tanks Facilities:
UST Facilities are points representing NJEMS sites with Underground Storage
Tanks regulated by NJDEP. This information represents UST facilities that are
regulated under N.J.A.C. 7:14B. The layer includes UST registration and
inspection information. The NJDEP New Jersey Environmental Management System
(NJEMS) serves as the database that supplies coordinates and descriptive
attributes from several tables to generate this GIS layer. This layer is
produced primarily for the NJDEP i-MapNJ ArcIMS interactive mapping web
application and ArcGIS (ArcView, ArcInfo) users.
The locations in the layer represent main entrance or front door locations for
the UST facilities. The majority (approximately 85%) of the UST facilities
locations were captured using differential GPS. Users should note that not
every site in NJEMS presently (as of July 2006) has an established coordinate
(GPS or otherwise). This means that additional UST facilities exist, but are
not mapped. NJDEP is continually working to acquire the locations of these with
GPS, location data submitted to permitting programs, and through address
matching techniques.

Urban Enterprise
Zones:
New Jersey has 32 Urban Enterprise Zones which
provide significant incentives and benefits to businesses that locate within
the zones. From the northern reaches of the state to its southern tip, there
have been dozens upon dozens of success stories made possible through New
Jersey's renowned UEZ program. Due to this success, the number of Urban
Enterprise Zones has expanded from an original 10 in 1984 to the 32 zones
today. Moreover, the program has helped create many full and part-time jobs
within the zones. The Urban Enterprise Zone program has become an effective,
efficient tool for urban redevelopment. This reputation was only solidified in
1997, when the non-partisan National Association of State Development Agencies
(NASDA) called the Garden State's UEZ program the "best in the nation," citing
its creation of many thousands of jobs and billions in private investment.

Vernal Habitat - Landscape Project: In 2001, ENSP partnered with
Rutgers University Center for Remote Sensing and Spatial Analysis (CRSSA) to
develop a method for mapping potential vernal pools throughout New Jersey.
Through an on-screen visual interpretation of digital orthophotography, CRSSA
identified over 13,000 potential pools throughout the state. A subset of these
pools was field verified and confirmed, with an 88% accuracy rate, to meet the
physical characteristics to qualify as a vernal pool (Lathrop et al. 2005). In
accordance with N.J.A.C. 7:7A-1.4, the term 'vernal habitat' includes a vernal
pool - or the area of ponding - plus any freshwater wetlands adjacent to the
vernal pool. Vernal habitat areas mapped in the Landscape Project rely upon
those data developed by the DEP and CRSSA to identify sites that should be
field checked for possible identification as vernal habitats areas. DEP staff
is in the process of field-verifying these pools. The Department also maps
vernal habitat areas based upon on-the-ground assessment of sites not captured
by the CRSSA mapping. The Landscape Project includes all of the
CRSAA-identified sites, as well as sites identified by on-the-ground
reconnaissance, categorized as either 'potential vernal habitat areas' or
'vernal habitat areas' as defined below: ' Potential vernal habitat area -
These are areas identified by CRSSA as possibly containing a vernal pool that
meets the criteria of a 'vernal habitat' pursuant to N.J.A.C. 7:7A-1.4. These
sites include sites that have been field inspected and have been found to meet
the physical characteristics of a vernal habitat, but for which biological
criteria have not yet been measured, as well as sites that have not been
checked by DEP staff. ' Vernal habitat areas - These are areas that contain
pools that have been field-verified by the Department and have been determined
to meet both the physical and biological characteristics of a vernal habitat in
accordance with N.J.A.C. 7:7A-1.4. All areas mapped as 'potential vernal
habitat areas' and 'vernal habitat areas' are derived from a point location
estimated to be the center of an individual vernal pool and include all areas
within 300 meters of the point. Note that the occurrence area is not intended
to suggest or correspond with any specific regulatory requirement. Rather, the
area added around the point accounts for variations in the size of individual
vernal pools, variations in the width of freshwater wetlands adjacent to the
pool, plus adjacent habitats sufficient to include the estimated home range for
vernal pool obligate species. If there is an overlap between areas mapped
around two or more nearby points, the boundaries are conjoined to generate
contiguous patches. If the resulting patch contains areas mapped as 'vernal
habitat area' and areas mapped as 'potential vernal habitat areas,' the entire
patch is labeled as a 'vernal habitat area.'

Water Source Areas:
This GIS data-set represents the source water areas for each active public
(community and non-community) surface water intake. The surface water source
water areas for all wells considered under the direct influence of surface
water (GWUDI) are also included. A surface water source water area represents
the surface ground area where water will flow overland past the intake
location. The source water areas were delineated from the intake location or a
controlling structure, such as a dam or weir, to the headwaters of all
tributaries upstream of the intake. For more information on the surface water
source water areas refer to http://www.nj.gov/dep/swap.

Watersheds (HUC11):
The USGS calls the watersheds Hydrologic Units. Each basic unit is a
unique feature, and is given a unique Hydrologic Unit Code (HUC), which
is 14 digits long. The HUC is hierarchical. Larger and larger watersheds can be
defined using different portions of the 14 digit code to define the watershed
boundaries. This layer shows boundaries of larger watershed units, which are
created by aggregating together several smaller HUC14 watersheds. All of
these smaller watersheds are physically connected to form a larger drainage
area. This is reflected in the HUC values of each , all of which share the same
first 11 digits. To add some utility to this layer, names of the
primary watercourses draining these areas have been added to this layer.

Watershed Management Areas:
The USGS calls the watersheds Hydrologic Units. Each basic unit is a
unique feature, and is given a unique Hydrologic Unit Code (HUC), which
is 14 digits long. The HUC is hierarchical. Larger and larger watersheds can be
defined using different portions of the 14 digit code to define the watershed
boundaries. The 21 management areas represent a further aggregation of
the basic HUC14 watersheds. In this case, all of the units share the same
first 8 digits, again indicating that they are all part of the same
major drainage system. Several HUC11 watersheds will be included in each
of the Watershed Management Areas. The NJDEP has chosen to use the 21 areas
shown in this layer as the basic management unit for watershed characterization
and assessment. Since these areas are defined by physical boundaries, they are
felt to be more ecologically sound units for environmental planning and
management than are the more typically used county or municipal boundaries.

Well Head Protection Areas (Community): A Well Head Protection
Area (WHPA) in New Jersey is a map area calculated around a Public Community
Water Supply (PCWS) well in New Jersey that delineates the horizontal extent of
ground water captured by a well pumping at a specific rate over a two-, five-,
and twelve-year period of time. The area of capture over two-, five-, and
twelve-years is defined using line boundaries and polygon areas generated with
Geographic Information System (GIS). GIS shape files are produced for each PCWS
well and for the set of all PCWS wells in a county. WHPA delineations are
conducted in response to the Safe Drinking Water Act Amendments of 1986 and
1996 as part of the Source Water Protection Program (SWAP). The delineations
are the first step in defining the sources of water to a public supply well.
Within these areas, potential contamination will be assessed and appropriate
monitoring will be undertaken as subsequent phases of the NJDEP SWAP. WHPA
delineation methods are described in
Guidelines for Delineation of Well Head Protection Areas in New Jersey .

Well Program Grid:
This grid is based on an old map series called the New Jersey Atlas
Sheets, and on a reference system based on them, called the New Jersey
Rectangular Coordinate System. The original 17 map sheets, numbered from 21
through 37, were produced with grid lines shown every 2 minutes of latitude and
every 2 minutes of longitude, producing a regular grid of Rectangles.
This rectangular grid forms the basis of the reference system. For each sheet,
groups of Rectangles are aggregated together to form Blocks. Each Block
in each sheet is given a number from 1 to 45. Within each BLOCK, each Rectangle
is numbered from 1 to 9. Rectangles are further divided into 9 sections
called Units, numbered 1 to 9, and each Unit divided into 9
sections called Parts, also numbered 1 to 9. Each of these smallest sub
divisions can identified by a unique 7 digit code composed of the Atlas Sheet
number, and the number of the Block, Rectangle, Unit and Part.
This 7 digit number appears as the label when the Well Program Atlas Grid is
displayed. This identifier is part of the historical well database, and is
still used on new permits. However, more accurate true State Plane Coordinates
are now also required. See the Well Program Help, under the Help Topic Menu,
for more information on the grid and the coordinate requirements.

Wetlands (2007):
The wetlands polygons included in this data set are extracted from the Land Use
2007 layer. Displayed are all polygons that have a TYPE07 code of 'WETLANDS'.
While these wetland delineations are not regulatory lines, they represent important
resource data in identifying potential wetland areas.The 2007 LU/LC data set is the
fourth in a series of land use mapping efforts that was begun in 1986. Revisions
and additions to the initial baseline layer were done in subsequent years from
imagery captured in 1995/97, 2002 and 2007. This present 2007 update was created by
comparing the 2002 LU/LC layer from NJ DEP's Geographical Information Systems (GIS)

Bureau of Geographic Information System (BGIS). LU/LC changes were captured by adding
new line work and attribute data for the 2007 land use directly to the base data layer.
All 2002 LU/LC polygons and attribute fields remain in this data set, so change
analysis for the period 2002-2007 can be undertaken from this one layer. The
classification system used was a modified Anderson et al., classification system. An
impervious surface (IS) code was also assigned to each LU/LC polygon based on the
percentage of impervious surface within each polygon as of 2007. Minimum mapping unit
(MMU) is 1 acre.ADVISORY:This metadata file contains information for the 2007
Land Use/Land Cover (LU/LC) data sets, which were mapped by Watershed Management
Area (WMA). There are additional reference documents listed in this file under
Supplemental Information which should also be examined by users of these data sets.

Wetlands (2012):
The wetlands polygons included in this data set are extracted from the Land Use 2012 layer. Displayed are all polygons that
have a TYPE12 code of 'WETLANDS'. While these wetland delineations are not regulatory lines, they represent important resource
data in identifying potential wetland areas.The 2012 LU/LC data set is the fifth in a series of land use mapping efforts that
was begun in 1986. Revisions and additions to the initial baseline layer were done in subsequent years from imagery captured
in 1995/97, 2002, 2007 and 2012. This present 2012 update was created by comparing the 2007 LU/LC layer from NJDEP's Geographic
Information Systems (GIS) database to 2012 color infrared (CIR) imagery and delineating and coding areas of change. Work for this
data set was done by Aerial Information Systems, Inc., Redlands, CA, under direction of the New Jersey Department of Environmental
Protection (NJDEP), Bureau of Geographic Information System (BGIS). LU/LC changes were captured by adding new line work and attribute
data for the 2012 land use directly to the base data layer. All 2007 LU/LC polygons and attribute fields remain in this data set,

2007 Color Imagery: Digital
orthophotography of New Jersey, distributed as a Web Map Service (WMS). There
are numerous layers in the service, one displaying the 2007 3 natural color
bands, another displaying 2007 3 band false color infrared (near IR). The
native data set spatial reference system is State Plane Coordinate System NAD83
Coordinates, U.S. Survey Feet. In most client software, the default spatial
reference system of the service will be Geographic Coordinates, WGS84. Several
other coordinate systems are supported (see Distribution Information
section).Multi-spectral digital orthophotography was produced at a scale of
1:2400 (1" = 200') with a 1 foot pixel resolution for the State of New Jersey
totaling approximately 8,162 square miles. The GeoTIFF tiles delivered to the
State of New Jersey were then converted to lossless JPEG2000 files, which are
used in this service.Aerial photography of the entire State of New Jersey was
captured during March-May, 2007. Two flight dates (4-30-07 and 5-3-07 were
rejected from the original 2007 flight due to excessive leaf conditions. Spring
2008 re-flights were planned and acquired in three missions dating: April 3rd,
10th, and 15th of 2008. The final orthophotos for parts of Warren, Hunterdon,
Sussex, Passaic, Essex, Union, and all of Bergen and Hudson Counties were
created utilizing both years of imagery.

2002 Infrared Imagery:
Digital orthophotography of New Jersey, distributed as an Open Geospatial
Consortium compliant Web Map Service (WMS). The map service includes an image
data set of digital color infrared orthophotography of New Jersey from 2002.The
native data set spatial reference system is State Plane Coordinate System NAD83
Coordinates, U.S. Survey Feet. In most client software, the default spatial
reference system of the service will be Geographic Coordinates, WGS84. Several
other coordinate systems are supported (see Supplemental Information; and the
Distribution Information section).Digital orthophotography combines the image
characteristics of a photograph with the geometric qualities of a map. Digital
orthophotography is a process which converts aerial photography from an
original photo negative to a digital product that has been positionally
corrected for camera lens distortion, vertical displacement and variations in
aircraft altitude and orientation. The imagery was captured at a negative scale
of 1" = 1600' in the spring of 2002, under leaf-off conditions, on
color-infrared film. The ortho-rectification process has achieved a +/-4.0 ft.
horizontal accuracy at a 95% confidence level, National Standard for Spatial
Data Accuracy (NSSDA). The final product has a nominal scale of 1:2400.The
georeferenced TIFF tiles delivered to the State of New Jersey were then
converted to lossless JPEG2000 files, which are used in this service. HOWEVER,
the Web Map Service does not have exactly the same spatial accuracy as the
original imagery, due to resampling. Files of the 2002 digital orthophotography
are available in several other formats, including downloadable MrSID tiles from
the New Jersey Image Warehouse, and both TIFF images and MrSID images on hard
media from the EROS Data Center. See separate metadata record for the MrSID
data for details.

1930 Black and White Imagery:
This OGC compliant Web Map Service includes a historical image data set of a
mosaic of black and white photography of New Jersey from the early 1930s. The
source imagery was hand cut to produce 261 mosaic tile prints on linen-backed
paper. The data set for this service was produced by scanning these mosaic tile
prints at 400 dpi and saved as TIFF images. The scanned TIFF images had an
approximate pixel resolution of 6.5 feet. They were georeferenced against
1995/97 color infrared digital orthophotography. The georeferenced TIFFs were
clipped and converted into other image formats. The digital product has not
been corrected for distortion or vertical displacement. They do not meet the
National Standard for Spatial Data Accuracy (NSSDA).
