Arlington County is using the 911 problems following the June 29 derecho as a learning opportunity.

In the days following the storm, which left 1 million customers without power in Virginia, Arlington and Fairfax counties experienced numerous problems with its 911 service, which made 911 unreachable for many emergency callers; some callers got a busy signal after calling 911, others heard nothing.

The problems were traced back to Verizon’s local communications backbone. In a report released last week, Verizon said the 911 problems started as a result of power outages.

Verizon’s central phone facility in Arlington lost power after the storm. It operated for a few hours on battery power, but a generator at the location failed to start (due to fuel line problems) and the facility lost power at 5:00 a.m. on June 30, after the batteries drained. Although Dominion restored power to the facility at 12:45 p.m., it took time for Verizon to recover its “telemetry” systems, which allow it to see and diagnose problems in its phone network, which had been been damaged by falling trees pulling down phone lines.

In Arlington, 911 service was spotty for days, but was deemed restored and stable by July 4.

In its report, Verizon said it has learned lessons from its 911 failure and will be improving its generator maintenance and redesigning some of its network systems to improve redundancy and reliability. Arlington County says it, too, has learned lessons from the experience.

Jack Brown, Arlington’s director of emergency management, said he’s hopeful that a 911 failure will never happen again. Should it happen, however, he said the county will have a more defined playbook of how to handle the situation.

During the days after the storm, Arlington advised those with emergencies to call the county’s non-emergency line at 703-558-2222. If all else failed, the county also staffed its fire stations so that residents could walk in and report an emergency. A “couple of people” did end up resorting to walking to fire stations, according to Brown.

Through the county’s efforts and somef luck, Brown said no one in Arlington was seriously harmed as a result of the 911 failure.

“We are very lucky that we didn’t have any life-threatening emergencies that couldn’t get through during that time,” said Brown. “We were very vulnerable during that period.”

In Virginia, a state panel is currently investigating the 911 failures, Brown said. Northern Virginia congressmen also called for the FCC to investigate the problems.

The National Weather Service has put Arlington and the surrounding areas under a Severe Thunderstorm Watch until 10:00 p.m. on Saturday. Conditions are favorable for strong storms, so anyone with outdoor plans for this evening should monitor weather reports.

A SEVERE THUNDERSTORM WATCH IS IN EFFECT UNTIL 10 PM FOR THE OUTLOOK AREA. THUNDERSTORMS WILL BE CAPABLE OF PRODUCING DAMAGING WIND GUSTS AND LARGE HAIL.


Arlington and the surrounding region is under a Severe Thunderstorm Watch through early Friday morning. A line of storms approaching the area may bring downpours, lighting and high winds.

From Arlington Alerts:

The National Weather Service has issued a SEVERE THUNDERSTORM WATCH for Arlington County and surrounding suburbs and the District until 1:00 am.

Those with outdoor plans this evening should monitor the skies and be prepared for threatening weather. Lightning is the number one severe weather killer in the US. If you are outdoors and a storm approaches, seek safe shelter indoors.

A SEVERE THUNDERSTORM WATCH means conditions are favorable for severe storms in and close to the watch area. Severe thunderstorms can and occasionally do produce tornadoes with little or no advanced warning. Residents should be on the lookout for threatening weather conditions and listen for later statements and possible warnings.


Arlington is hoping to receive some federal funds to cover the hundreds of thousands of dollars it spent during emergency response to the June 29 derecho storm.

County Manager Barbara Donnellan got the ball rolling by declaring a local emergency on June 30. Nearly 50 other Virginia localities did the same. Yesterday, Governor Bob McDonnell formally requested assistance for the state from the the Federal Emergency Management Agency, estimated at $27.5 million. Now it’s up to President Obama to either approve or deny the disaster funding.

Jack Brown, Director of the Arlington County Office of Emergency Management, explains that to be eligible for federal funds, the county must incur more than around $700,000 in expenses. So far, the bill from the June storm adds up to approximately $802,000, which includes costs for personnel, equipment and debris removal. The total could increase as more numbers are finalized.

Brown offers a reminder that there’s a lot of paperwork and a long review process involved, and that reimbursements filter in gradually once approved.

“They don’t just cut one check for the whole amount,” he said. “We went through this after the huge snowstorms of 2009 and 2010. It’s about a year long process.”

Arlington didn’t get all the funding it requested following those snowstorms, but it fared better than many surrounding jurisdictions, according to Brown. He credits all of the individual departments involved for collecting and sorting the receipts and data that had to be submitted. The county received a total of $1.6 million, covering one storm in December 2009 and two in February 2010.

Although receiving reimbursements often involves an arduous process, Brown said the end result makes up for it.

“Once we know there has been a federal declaration, then we would go through the process with FEMA and the state, and go through all those records,” said Brown. “But it’s worth it at the end of the day.”

For now, Brown said the county continues to calculate its expense requests from the derecho, while waiting for word from the President.

“Other areas of the country were hit harder than we were with different storms, so we’re all just waiting,” said Brown.


A Severe Thunderstrom Watch has been issued for Arlington and the surrounding region through 8:00 p.m.

The National Weather Service says the potential exists for storms and damaging winds this evening.

A SEVERE THUNDERSTORM WATCH IS IN EFFECT UNTIL 800 PM EDT. SHOWERS AND THUNDERSTORMS WILL CONTINUE TO DEVELOP THIS AFTERNOON ALONG AND SOUTH OF A SLOW-MOVING COLD FRONT. SOME STORMS WILL BECOME SEVERE AND WILL BE CAPABLE OF PRODUCING DAMAGING WIND GUSTS AND POSSIBLY LARGE HAIL.
