Vienna tends to flood. Recent heavy rainfall has not only impacted local streams, but locals may have seen high water in Vienna’s downtown area near the Town Green.

It’s an issue that town staff have been working for years to address, and solutions have been identified, but year after year have remained unfunded.

A report presented to the Vienna Town Council in December 2016 examined the state of Vienna’s sewer infrastructure, particularly at the intersection of Maple Avenue and Center Street N. in the center of the town.

The study found that there were places that experienced significant flooding where existing sewer infrastructure was unable to handle storm volume. Town staff confirmed that improvements suggested in the study were included in the CIP, but have yet to receive funding.

The report indicates that there are three major locations for flooding in three different areas. According to the report:

  • In moderate storms, flooding first occurs along Center Street at the location of the N Condos building and Starbucks parking lot.
  • In more intense storm events, flooding occurs in the area of the Freeman House Museum, at Church Street NW and Dominion Road NE.
  • Flooding also occurs near the intersection of Mill Street NE and Ayr Hill Avenue.

The report notes that flooding at the Starbucks is generally seen as the first sign of storm sewer capacity issues. The report noted that the ponding at these issues is more indicative of capacity problems than issues with draining.

“The ponding in all three areas of concern is a result of storm sewer surcharge, rather than surface drainage issues,” the study said. “This is evidenced by the ponding that occurs during a storm event and the rapid dissipation of ponded water immediately after the rain intensity subsides.”

The study assessed every outfall and junction in downtown Vienna and found that the system is unprepared for handling severe storms.

“The flow capacity of portions of the existing storm sewer system is insufficient to carry the stormwater calculated for a 10-year frequency storm,” the study said.

Ten-year floods are floods that have a 10 percent chance of happening in any given year, though there is some concern that this type of descriptor can lead to a false sense of security for those in areas prone to flooding.

Crucial to any fix to the local sewers, the study said, would be preventing flooding at the Freeman House and Starbucks, which are most prone to flooding.

The report recommended clearing debris and obstructions to sewer flow but that more substantial improvements will be needed over time.

“Even with clean sewers, the flow capacity in the piped portion of the system is lacking in two general areas,” the study said. “Sewer system improvements will be needed if the system is expected to move the flows resulting from a ten-year frequency storm, without undue flooding.”

A burst pipe has closed a handful of stores in Tysons Corner Center mall.

Around 11 a.m., water spilled into stores in the Nordstrom wing of the mall. The Aveda and White House Black Market both faced substantial water accumulation and were evacuated.

Frozen pipes, and subsequent bursts, are a common hazard of sudden temperature drops.

Janitorial staff are currently on scene cleaning the flooded areas, but an employee at Aveda said there store is likely to be closed for the remainder of the day. The damage to the stores has not yet been determined.

At one point, a delivery person came along with boxes of merchandise and asked whether or not to drop it off inside. The employee shrugged and pointed to the flooded store.

(Updated at 2:45 p.m.) Rising waters due to heavy rain have prompted a road closure west of Tysons.

Fairfax County Police closed Old Courthouse Road at Besley Road after floodwaters from nearby Wolftrap Creek inundated the roadway. There’s no word on how long the closure will remain in place.

It was the only reported closure in the McLean police district as of 1 p.m., though others had been reported around Fairfax County, including:

  • Fairfax Station Road at Innisvale Drive due to water in the roadway
  • Woodburn Road at Spicewood Road due to water in the roadway
  • Burke Lake Road at Kilkenny Lane due to water in the roadway
  • Burke Road at Heritage Square Drive due to water in the roadway
  • Fox Mill Road at Folkstone Drive due to water in the roadway
  • Lawyers Road between Galloping Way and Whipporwill Road due to water in the roadway

There were also scattered reports of standing water on local roads that wasn’t high enough to prompt closures but did create a driving hazard.

Parts of Fairfax County, meanwhile, are under a Flood Warning Thursday evening.

Fairfax County is again reminding drivers to “turn around, don’t drown” when encountering flooded streets. The fire department posted the following VDOT safety video earlier today.
