  Description:

  • Abstract:
    • ADVISORY: NJDEP is in the process of updating this metadata file to comply with the FGDC's Content Standards for Digital Geospatial Metadata (CSDGM). In order to make this data available immediately to the public, NJDEP is releasing it to the New Jersey Geographic Metadata Clearinghouse with the existing metadata. The updated metadata will be made available after the review and verification of the content of the metadata has been completed.
      This coverage is a ArcView 3.x Geographic Information System shapefile that delineates New Jersey drought regions, counties, and municipalities. Drought regions provide a regulatory basis for coordinating local responses to regional water-supply shortages. The six drought regions are based on watershed and water-supply considerations. Drought region boundaries coincide with municipal boundaries as referenced by the N.J. Dept of Environmental Protection (NJDEP). Each municipality in New Jersey is assigned to a drought region based on the watershed covering and supplying water to the municipality. Each data record of the file includes name and numeric code entries for counties and municipalities, and names of drought regions. The second version of the drought regions differed from the original delineation in two ways: 1) The number of drought regions were expanded from five to six in order to account for water-supply issues identified for the New Jersey coastal plain. The original version included the north part of the Coastal Plain in the central region. The second version separated a north coastal region, consisting of Monmouth and northern Ocean Counties, from the coastal region to the south. 2) Municipalities in Mercer County receiving water from the Trenton Water Dept. were moved into the southwest region from the northwest. Pennington and Hopewell boroughs were also moved to the southwest region. This is the third version of the drought regions and was released in May 2004. There are two changes from the second version. Roosevelt Boro in Monmouth County was moved to the southwest drought region (from the coastal north) and Berlin Twp in Camden County was moved to the coastal south drought region (from the southwest). Both changes were made in recognition of the location of actual water supply to these municipalities.

    Purpose:

    • The drought regions are designed to assist the DEP in declaring drought warnings and emergencies in New Jersey during times of decreased precipitation, and current or anticipated water-supply shortages. By having different regions it is possible for the State to declare drought warnings or emergencies in different regions. These warnings and emergencies are declared by the Governor of the State of New Jersey. The State's response to a drought is coordinated by the NJDEP Water Supply Element.

    Supplemental Information:

    • Njdrghtregmun is an ArcView shapefile. A shapefile is composed of three separate files having the extensions.shp, .shx, and .dbf. The *.shp file contains the spatial information, the *.shx file is an index file,and the *.dbf file contains the polygon attribute information.
      This product includes the files njdrghtregmun.shp, njdrghtregmun.shx, njdrghtregmun.dbf. It consists of vector data with arc-node topology. Spatial objects include polygons with x,y coordinates. There are 582 polygons.

Data Quality Information

Section Index

• Attribute Accuracy:
  • Attribute Accuracy Report:
    • A dBase IV relational database file was prepared that included fields for the Federal Identification Processing Standard (FIPS) numbers for counties and municipalities in New Jersey, and names of municipalities, counties, and drought regions. Records for all fields were completed for each municipality. The dBase file was added to an ArcView project along with the NJDEP stmun coverage of municipalities. The dBase file was joined to the feature table of the stmun coverage using the municipal FIPS field. The resulting theme was saved as a new shapefile named njdrghtregmun.shp
      The accuracy of this theme reflects the accuracy of the NJDEP source coverage (stmun). The stmun coverage stems from partial orthophotoquad correction of municipal boundaries digitized from U.S. Geological Survey 7-1/2' topographic quadrangle base maps. The stmun coverage was compiled to meet horizontal accuracy standards of the 1947 National Map Accuracy Standard, but have not been tested for geospatial positional accuracy. Please refer to the NJDEP metadata file catalog for more information on the source coverage. The metadata catalog is an unpublished computerized directory on-file at the NJDEP, Office of Information Resources and Management, Bureau of Geographic Information and Analysis, PO Box 428, Trenton, NJ 08625.

  Logical Consistency Report:

  • New Jersey is divided into six drought regions. These regions are based on watershed and water-supply considerations. The six regions are central, coastal north, coastal south, northeast, northwest, and southwest. The boundaries of the drought regions correspond to municipal boundaries.
    Municipal boundaries in New Jersey were gathered from USGS topoquads and other sources in 1987. Since that time, updates to the data have been limited to noting consolidations of boundaries. The scale of the original data varies, relying primarily on 1:24,000 topoquads

    Process Step:

    • Process Description:
      • Drought regions are based on, but differ from, the five watershed regions defined by the NJDEP. The arrangement of the drought regions account for certain regulatory considerations and the architecture of their water-supply distribution systems. Watershed boundaries primarily occur along natural topographic divides between drainage basins. In contrast, drought-region boundaries match with municipal boundaries in order to facilitate the administration of water-restriction practices. Municipalities also receive water supplies from different sources including man-made water-distribution systems. The drought regions were created to reflect many of these water-supply factors.
        Version 1 of the drought regions were defined using the following logic:
        
        (1) Drought regions were initially based on the New Jersey water regions as defined by the NJDEP Watershed Management program. Municipalities that were covered by two or more water regions were assigned to the region covering the largest fractional percentage of the municipality.
        
        (2) Monmouth County municipalities were assigned to the central region because the water sources and transfer methods more closely resembles municipalities in the central region than in the southeast region.
        
        (3) Municipalities in the Delaware Bay watersheds were assigned to the southeast region rather than the southwest region because most of the water supplied to this area is groundwater, whereas surface water is a more important source of water supply for the southwest region.
        
        (4) Municipalities near region boundaries were evaluated and assigned to a region having the most similar water-supply characteristics.
        
        Changes made in Version 2 reflect comments received on Version 1, and were amended in the following manner:
        
        (5) The southeast region was split into north and south coastal regions based on water-supply considerations.
        
        (6) Trenton, Lawrenceville, and Mercerville of Mercer County partially depend on water withdrawn from the Delaware River south of the fall line. They were moved from the northwest region to the southwest region so that Mercer County is only spit among two regions rather than three. Washington Twp, Hopewell and Pennington Boroughs of Mercer County were also moved to the southwest drought region (they were previously assigned to the northwest region).
      • Version 3 of the drought regions was amended in the following manner after a they had been used for several years and 2 minior inconsistencies recognised. These changes were made based on analysis of potable water to these municipalities.
      • (1) Roosevelt Boro in Monmouth County was moved to the southwest drought region (from the coastal north).
      • (2) Berlin Twp in Camden County was moved to the coastal south drought region (from the southwest).
