In February and May 2015, respectively, the Fairfax Board of Supervisor’s and the County Planning Commission approved Dominion Energy’s application to remodel its existing Idylwood Substation at Shreve Road.

After several meetings within the community, Dominion Energy’s project team has been able to incorporate a number of modifications based on community input. The following highlights many of those changes:

  • Dominion Energy has achieved the full 35-foot screening/buffer adjacent to Shreve Road
  • An area of existing trees along Shreve Road has been maintained
  • Dominion Energy has achieved the full 50-foot screening/buffer adjacent to nearly all homes along Holly Manor Drive (buffer areas towards the front of subdivision at the intersection with Shreve Road could not achieve full 50-feet due to substation operation constraints)
  • All backbones have lowered to 75-feet from 95-feet in height
  • Taller proposed vegetation has been added in the corner of the site near the Holly Crest entrance. This area is not underneath overhead transmission lines and thus can feature some taller trees
  • More robust landscaping areas have been added adjacent to the southern substation property line
  • The back lower yard future expansion has been removed from the application

Our crews are committed to working safely and courteously in your neighborhood and will utilize signage and flagmen during our work hours. We appreciate your patience as we work to improve reliability and service in your area.

This work is separate from activities associated with the proposed expansion project, which is still under review for approval with Fairfax County.
