“We have had a very strong response to that,” Shields said about the advertisement for the task force, which can have up to seven members.
The deadline to apply is this Friday (Nov. 15), Shields said.
“We are looking for geographical diversity on this panel and the ability to have a city-wide perspective,” Shields said.
In response to residents’ comments that the task force should include sanitary sewer, Shields said that the rationale for not including that is because it is a different engineering problem, skillset and solution.
“To keep this work focused on stormwater was by decision,” Shields said.
When the task force is ready, Shields said that there will be an organizational meeting about the scope of the group.
Shields also pointed out some “big improvements” recently with stormwater management, including work on the washed-out flood wall at Tripps Run.
He added that work is underway to add water-tight man-hole covers in areas where water pools in the streets.
The city may also implement a program — similar to the one in Alexandria — to help homeowners considering a backflow device in their homes, Shields said.
“That would be a targetted program for areas where we have documented backflow where we can provide that assistance,” Shields said.
The program would need approval from the City Council, Shields said.
“That’s not the solution, but it does provide some additional resilience for homeowners,” Shields said, adding that he hopes the program will be available by the end of the calendar
Updated at 8:30 a.m. — Power has been restored.
Roughly 500 Dominion Energy customers are without power as a storm sweeps through the area on Halloween night.
One power outage is affecting 326 customers in McLean, spanning from Georgetown Pike to Route 694 just west of I-495.
Another one is affecting 228 customers where the Dulles Access Road intersects with Leesburg Pike above the Spring Hill Metro station in Tysons.
The causes of the outages are pending investigation, according to Dominion’s outage map.

Design work is set to start at the end of the year to look for ways to reduce flooding in a McLean neighborhood.
The Tucker Avenue Neighborhood Stormwater project aims to reduce flooding and erosion, while improving stormwater drainage.
The area was reportedly damaged from severe flooding in July, along with several spots in McLean.
The project, which is located in the Pimmit Run Watershed, will look at the current drainage and stormwater infrastructure in the neighborhood and within a 67-acre drainage area that leads to Pimmit Run. The project is divided into three areas.
“All three areas have inadequate drainage systems that result in street, yard and/or house flooding during certain storm events,” according to Fairfax County. “Additionally, portions of lower Tucker Avenue are in a FEMA floodplain along Pimmit Run that creates further drainage problems.”
Fairfax County has teamed up with the Virginia Department of Transportation on the project, according to the county.
“A concept design is currently scheduled for late December or early January,” Dranseville District Supervisor John Foust said in an email.
So far, Foust was able to share that the project will upgrade the conveyance system and propose a new stormwater management system.
Foust has said that this is one of several projects meant to address flooding issues in McLean.
“Coordination with homeowners including [the] acquisition of additional storm drainage easements will be required prior to final design and construction,” according to Fairfax County.
Construction costs are expected to total $3.7 million and will be funded through Fairfax County’s Stormwater Service District fee.
New systems will be installed along VDOT’s right of way based on the neighborhood drainage pattern, Foust said.

One Fairfax County official is urging the county to take more responsibility for stormwater management regardless of its liability.
Dranesville District Supervisor John Foust represents McLean, Great Falls and Herndon on the Board of Supervisors. After major flash flooding in July, Foust saw severe storm damage throughout McLean — from two severely damaged roads to flooded yards and fields.
“This is the issue de jure out in the communities after July 8, at least in my neck of the woods,” Foust said. “This is what I hear about all the time.”
Randy Bartlett, the director of the county’s Department of Public Works and Environmental Services, gave a presentation to the Board of Supervisors about flood mitigation activities on Tuesday (Oct. 8).
Some of Bartlett’s proposed policy recommendations included using 100-year storm benchmarks when upsizing pipes, requiring new developments to capture a certain amount of rain and designating overland relief paths on plats.
“I think that these are good recommendations,” Chairman Sharon Bulova said, adding that the county needs to designs for the 100-year storm and consider upsizing at new developments.
Foust agreed with Bulova and said that Bartlett suggested “some good alternatives,” before pushing the county to do more.
Bartlett said that the county will install backflow valves that residents then need to maintain.
“I know we offer constituents options to make investments to limit the ability of our sewer systems to back up into their basements when our sewer systems get overflowed with stormwater,” Foust. “I think that should be our responsibility.”
Foust added that the county either needs to find a way to keep stormwater out of the sewer systems or — if it does — to at least make sure it doesn’t get into constituents’ basements.
Overland relief is causing dangerous situations, Foust said.
“We have to think about getting more of this water into a conveyance system that is not free-flowing in these neighborhoods,” he said.
Aside from the county’s efforts, Foust also said that more state funding is needed.
“We have neighborhoods being literally destroyed when it rains hard,” Foust said.

Falls Church residents may have noticed that work has started on several projects to minimize flooding damage and better manage stormwater.
City Manager Wyatt Shields gave the City Council an update on stormwater management projects at Monday (Sept. 23) night’s meeting.
Smaller ones, like drainage issues between Laura and Poplar drives and flooding issues at 913 and 915 blocks of Lincoln Avenue, will be handled in-house and paid for by the current stormwater operating budget, he said.
Residents can expect work to finish on those by the end of the year.
Meanwhile, the city has reached out to GKY about five larger watersheds, including:
- the area by W. Columbia Street and Shadow Walk
- the Hillwood Avenue area
- the Sherrow Avenue area
- E. Columbia Street and Harrison Branch Tributary
- Ellison Branch Stream near new homes on Lincoln Avenue
“Ultimately, we will get the options and get the costs and we will need to work together to prioritize our resources for where they can do the most good for the buck,” Shields said.
The timeframe will be determined during budget discussions in the winter, and work won’t begin on those larger projects until July, he said.
“People have been seeing us out in the field doing the initial walkthroughs with the engineers,” he said, adding that city staff is waiting to get a cost estimate from GKY before alerting the residents.
“It sounds like we’re making a lot of progress, I think if we can communicate better to those residents and let them know that work is happening, that would be very reassuring to people,” Councilmember Letty Hardi said.
Shields also said that the wing wall on Tripps Run has been completed, eliminating a flooding risk to residents on Sherrow Avenue.
“It’s good to get that resolved,” he said.
The Tysons area is under a Severe Thunderstorm Warning, which includes the D.C. area.
The warning will last until 5:45 p.m. People can expect winds up to 60 miles per hour with “quarter size hail.”
More from the National Weather Service:
At 4:57 PM EDT, severe thunderstorms were located along a line extending from near Great Falls to Fairfax to near Bull Run, moving east at 25 mph…
IMPACT…Damaging winds will cause some trees and large branches to fall. This could injure those outdoors, as well as damage homes and vehicles. Roadways may become blocked by downed trees. Localized power outages are possible. Unsecured light objects may become projectiles.
