The purpose of the proposed Zoning Ordinance amendment is to allow implementation of the updated Reston Master Plan. The Reston Master Plan Special Study was initiated in 2009, in recognition of the changing pattern of land use and development over time in Reston, facilitated in large part by the planned arrival of Metrorail. The study concluded in 2015 and resulted in the Reston Master Plan being amended in two phases in 2014 and 2015. This Zoning Ordinance amendment proposes changes to the density provisions set forth in Sect. 6-308 of the Zoning Ordinance, specifically for the Reston PRC District. The amendment proposes an increase in the maximum overall density permitted in the Reston PRC District to a number between the current 13 persons/acre up to 15 persons/acre. The amendment would also allow the Board to approve residential development up to 70 dwelling units per acre for certain high density residentially designated properties in the Reston PRC District that are located within the transit station areas (TSAs) and planned for “mixed use,” if the proposal is in accordance with the adopted Comprehensive Plan. Development in the Reston PRC District is quickly approaching the Zoning Ordinance’s density limit of 13 persons/acre.
