At the July 10, Fairfax County Board of Supervisors meeting, County Executive Edward L. Long Jr. presented a report about how the county responded to the derecho thunderstorm that struck the area Friday, June 29, at approximately 10 p.m.
The county activated its Emergency Operations Center (EOC) about an hour after the storm struck and deactivated it at about 4 a.m. Saturday, “since there were no indications of massive phone or massive power outage,” Long reported. It was re-activated at 9:30 a.m., once the true extent of the disaster was discovered.
On Saturday, July 30, there were more than 230,000 power outages across the county, affecting approximately 55 percent of the county’s meters.
9-1-1 service was also affected, and the report states, there was “no loss of life due to 9-1-1 phone service outage,” the report states.
On June 30, power outages affected more than 120 traffic intersections; more than 50 Fairfax County public school sites; and several public safety facilities, including fire stations in Annandale.
Forty of the county’s wastewater pumping stations lost power on June 30. All of them lost Supervisory Control and Data Acquisition system communications, which means county personnel were unable to remotely monitor wastewater pumping station operations.
On the afternoon of June 30, the Falls Church Water Utility advised customers to boil tap water before using it for drinking or cooking. That affected Fairfax County residents in portions of Tysons Corner, Vienna, Dunn Loring, and Merrifield.
All county facilities that had electricity were made available as “cooling centers,” offering relief to people without access to air conditioning.
Volunteer Fairfax representatives in the EOC made phone calls to all 161 people on the County’s Special Medical Needs Registry to see if they needed assistance.
About 4,000 tons of solid waste brush was collected along I-95 and I-66 between June 30 and July 6.
