While Fairfax County's GIS data does contain some information about easements, it is unfortunately neither comprehensive nor authoritative. To ensure that all legally recorded easement information is shown, a subdivision and/or easement plat must be viewed.
These official records may be found in the Fairfax County Circuit Court’s Court Public Access Network (CPAN) system. They may also be found in the deed books available at the Land Records Division of the County Circuit Court. They are located in Suite 317 of the Fairfax County Courthouse (4110 Chain Bridge Rd). For more information, call 703-691-7320, or visit their website.
Many of these plats may also be viewed in hard copy format at the Land Development Services agency. Please contact Records and Information in Suite 555 of the Herrity Building. For more information, call 703-324-1775, or visit their website.
