Recorded Maps


The Public Works Department uses an electronic records system known as Laserfiche Weblink. It is used by municipalities nationwide to retrieve and manage documents. This system allows for citizen access to various public records. Public Works records currently available via Weblink include:

  • Assessor Parcel Books which are annotated with additional map references
  • Archived Assessor Parcel Books, which include superseded pages
  • Recorded Maps (Subdivisions, Minor Subdivisions, Records of Survey and Corner Records)
