STEER Watershed Mapping

The following shapefiles were created by Horsley Witten solely for the purposes of the STEER watershed planning effort.  They are not intended to supersede official mapping data used by DPNR or other territorial agencies.  Shapefiles are in standard 'NAD_1983_UTM_Zone_20N' projection used by DPNR, unless otherwise noted.

  • STEER Watershed Boundaries (153 KB) — polygons for watershed and subwatershed delineations. The watershed boundary is derived from DPNR Jersey Bay and Redhook Bay watershed boundaries. Subwatersheds were created based on looking at the guts and topography layers provided by DPNR.  The existing gut line file (UVI, 2007) was revised in 2013 based on aerial interpretation and watershed field work; changes primarily were along roads in the Bovoni Subwatershed and along the mainstem of Turpentine Run and Nadir guts. 
  • STEER Watershed Projects (11 KB)— point file showing the location of potential restoration sites identified as part of the watershed planning effort, as well as a polygon file showing potential parcels for easements or acquisition for stormwater improvements or habitat conservation.
  • STEER Land Use (881 KB)— polygon files for revised land use and impervious cover layers.  The most recent DPNR landuse layer was modified primarily where parcels were classified as “undeveloped,” but aerial imagery clearly showed recent development.  The Impervious cover file was generated from Digital Coastal Services (2007) land cover mapping.  Also included are polygon and point files showing locations of neighborhoods, resorts/condos, marinas, and schools which were based on field work.
  • STEER Infrastructure (345 KB)— point files with locations of existing stormwater management facilities and wastewater treatment facilities (WWTP and small package plants) based on field observations on 2011 by HW.  This list of facilities is not meant to be exclusive, rather it is intended as a starting point for a future DPNR database. Also included are the sewer service areas, which are a combination of polygon, point, and line files showing approximate locations of trunk lines, parcels serviced, pump stations, and future areas for expansion generated from informal discussions with VIWMA.  This map data is for planning purposes only and is not intended to accurately depict pipe locations, etc.  Also included is a Septic Failure Potential polygon file originally created by Cadmus (2011) with classification of parcels by high, medium, or low failure potential for conventional OSDS.
