Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This polygon dataset represents impervious surface in Fairfax County. This dataset also includes areas that drain to Fairfax County. This includes portions of City of Fairfax, City of Alexandria, Falls Church, Arlington and Loudoun County. The impervious area in Fairfax County was originally captured in the 2017 planimetric data update. The dataset has since been updated using the 2022/2023 Eagleview orthophotos. The source impervious data for Falls Church is from 2017. The source impervious for Arlington and Loudoun is updated periodically. This dataset is a snapshot of the current impervious data from each jurisdiction on April 1, 2025. Fairfax County Land Development Services will update this layer when Fairfax County receives updated planimetric data. This dataset is designed for use in the Drainage Basin Delineation Tool. The tool delineates drainage basins and calculates the impervious area. </SPAN></P><P><SPAN>Contact: Land Development Services </SPAN></P><P><SPAN>Data Accessibility: Publicly Available</SPAN></P><P><SPAN>Update Frequency: Never</SPAN></P><P><SPAN>Last Revision Date: 4/1/2025</SPAN></P><P><SPAN>Creation Date: 4/1/2025</SPAN></P><P><SPAN>Layer Name: LDSAMGR.COUNTY_IMPERVIOUS_2023</SPAN></P></DIV></DIV></DIV>
