Geographic Information Systems (GIS)

Public Works is responsible for the operation and maintenance of the Borough's GIS system.  Although the GIS system benefits and serves all the Borough Departments as well as the general public, the Public Works Department coordinates and allocates resources that benefit individual Borough Departments.  Data layers maintained and managed by the Public Works Department are:
  • Aerial Photography
  • Buildings Footprints
  • Easements
  • General Planimetric information
  • General Cadastral data
  • Parcels
  • Streets & Street Centerline
  • Topography
  • Utility Infrastructure
  • Zoning

Available Maps


To help keep the geographic information system (GIS) viewer working properly we need your help. Please report any issues or problems to the GIS Department.
