Mapping Applications Available

Jade logoThe Jade is a Geographic Information System (GIS) web application that provides an easy way to view, search, and analyze geographic information.

  • One map application, available on any device, with over 170 layers to view, combine and analyze.
  • Detailed property reports, especially useful for land development.
  • Save, share and print your map creations.

Site Records Viewer

Site Records Viewer map sectionThe Site Records Viewer (SRV) provides access to thousands of approved site records. Download or view PDFs of approved site-related plan records, such as infill lot grading plans, resource protection area studies, and site plans. The SRV allows anyone to search for site development records geographically, or by a search function.

The Site Records in this application are tied to the original tax map parcel found on the record. Due to the age of the records many of the parcels are expired. Fairfax County only maintains GIS data for parcels dating back to 2000. This means that any Site Record on a parcel that expired prior to 2000 will not be found in this application. However, these records can still be accessed by submitting a Records and Information Management Records Request form.
