Resource Protection Areas

The map displays the general locations of RPA boundaries for planning purposes and the actual limits may be further refined by site-specific field studies conducted at the time a site-related plan is submitted to develop a property. These polygons represent areas regulated under the Fairfax County Chesapeake Bay Preservation Ordinance.  The Ordinance and Countywide map were initially adopted in 1993 and have been amended several times since.  Effective dates of these amendments are evidenced by the different RPA “types” in this layer.  For more information: Chesapeake Bay Preservation Ordinance | Land Development Services (fairfaxcounty.gov)
