Arlington County to buy a home in Westover for $1.5M for flood mitigation

5840 18th Street N. (via Google Maps)

Arlington County is buying its fourth home for stormwater mitigation — this time in Westover, near the neighborhood’s main drag.

The Arlington County Board is set to approve the terms of the purchase, including a price tag of $1.5 million, on Saturday. The home is located at 5840 18th Street N., across the street from Cardinal Elementary School and the Westover Library branch.

This purchase is part of its voluntary property acquisition program targeting homes in the Spout Run watershed, which saw severe flooding during rain storms four years ago. Since agreeing to purchase its first home in March, the county has purchased a total of three — all in the Waverly Hills neighborhood.

The goal is to create “overland relief,” or a safe path for stormwater to flow to a stream or storm drain during large rain events. The county contends the existing stormwater systems and public space are not able to handle floods like those seen in 2019.

The newest acquisition is a stone’s throw from the stormwater detention vault at Cardinal Elementary, which was also a “community-driven project following the devastating losses and impacts to surrounding businesses and homes from the July, 2019 storm event,” according to the county.

The single-family home will be demolished, with viable parts of it salvaged for new purposes, if applicable.

BREAKING: Water rescue underway in Pentagon City

Previous Image 1/12 Next Image

(Updated at 2:30 p.m.) Arlington County firefighters conducted water rescues in the Pentagon City area this afternoon amid torrential downpours.

Initial reports suggest that three cars were stuck in high water along S. Joyce Street between Army Navy Drive and Columbia Pike, and that multiple people — including an elderly person with disabilities — were stranded, either in their vehicles or on the concrete median.

Another report suggested that the water was so high that at least one of the vehicles was floating. On traffic cameras, water could be seen streaming down from the I-395 overpass above.

A large contingent of fire department resources, including boats, responded to the scene. As of 2 p.m., ACFD said it was clearing the scene after everyone was rescued and no one needed to go to the hospital.

Much of Arlington, including Pentagon City, is under a Flash Flood Warning due to slow-moving, heavy downpours. The flooded portion of S. Joyce Street remains closed.

New bridge over Lubber Run to replace two destroyed in 2019 flooding

Previous Image 1/5 Next Image

Arlington County is working on a replacement for the two bridges over Lubber Run destroyed in severe flash flooding four years ago.

The Arlington County Board is set to discuss a $360,000 construction contract for a new pedestrian bridge at its meeting this weekend.

Flash flooding in 2019 washed away six pedestrian bridges in Arlington, including two in Lubber Run Park and four in Glencarlyn Park. The overall damage to county property was estimated at $6 million at the time.

On Saturday, the Board will consider approving the new bridge in Lubber Run, in place of the two that were destroyed. The contract — of about $329,000 with a $33,000 contingency — is expected to go to Fairfax-based Bright Masonry.

A lower bidder — by just over $30,000 — was “deemed nonresponsive” by county staff, according to a report to the Board.

The project’s goal is to “design one new bridge in the most suitable location for enhancing accessibility around the park,” the staff report said.

One of the bridges in Glencarlyn Park that was washed away was replaced in February of last year.

The proposed construction for Lubber Run involves building one new bridge in the southwest portion of the park to replace the previous two, as explained in the county’s project webpage.

“Through our community engagement and engineers’ analysis, we have found that this location will provide a significant, positive impact on park users and supports the community’s interest,” the webpage noted.

For parkgoers, the proposed bridge will provide access from Lubber Run to Edison Park, staff said. The bridge would also provide a connection between the southwest portion of the park and its east side.

Construction is estimated by staff to take around 12 months and seeks to minimize environmental harm.

“One tree, with exposed roots on the bank, will need to be removed. It already has a very low chance of survival due to its current condition,” the project webpage said. “We will plant healthy trees in the same general areas, which will better support our tree canopy in the long term.”

Arlington County Board candidates call for more regulations, incentives and public education to mitigate flooding

Previous Image 1/3 Next Image

This spring, Arlington County began buying up properties in the Waverly Hills area to combat flooding.

Already, despite some concerns about how the program would work, three residents have agreed to sell their homes. The county will tear them down and replant the land so water has a place to flow during large rain storms.

All seven Arlington County Board candidates — six of whom are vying for the support of the local Democratic party this primary — say the county needs to change its land-use policies and get more people on board with adding stormwater infrastructure in their backyards, in order to make neighborhoods more resilient to a predicted increase in flooding.

“The July 2018 and 2019 floods in particular really drove this home for us — we had some real life-safety issues pertaining to flooding,” Susan Cunningham said in a forum hosted by nonprofit advocacy group EcoAction Arlington last week.

“[It] highlighted that, not only because of climate change but really because of lack of long-range planning, we have very outdated stormwater management systems that we don’t have a budget to improve,” she continued. “We do have a lot of catch up to do.”

Since the floods, Arlington County has taken steps to manage stormwater beyond buying homes for flood relief.

Starting next year, Arlington will fund its stormwater management plan with a stormwater utility fee. The county will charge property owners a rate based on how much of their property is covered in hard surfaces, like roofs and driveways. (Currently, it is funded by a tax based on property assessments.)

Other changes include new regulations requiring single-family home construction projects to retain more water and some $90 million in bond referenda from 2020 and 2022 for stormwater projects.

Developers of single-family homes report higher construction costs due to retention regulations. Bonds and the new stormwater utility fee, meanwhile, could spell higher taxes for residents.

So, in this race, some candidates say the county should examine how its own policies encourage flooding before requiring more of residents.

Cunningham and Natalie Roy, both of whom have opposed the recently adopted Missing Middle zoning changes, that starts with reducing the allowable buildable area that homes can occupy on a lot.

“This is something that we should’ve done 10 years ago and definitely something we should have done before approving the misguided [Missing Middle] plan,” Roy said.

Perennial independent candidate Audrey Clement said she would call for the repeal of Missing Middle, linking the new policy to tree loss and thus, increased flooding.

She said she would also end a practice among developers to subdivide lots to circumvent state environmental ordinances preventing construction near protected land along Arlington streams called “resource protection areas,” or RPAs.

“It was by this sleight of hand that the county permitted a tear-down McMansion in a North Arlington RPA in 2018 but also the destruction of a 100-foot state champion redwood on the same lot,” she said.

Arlington to buy two more homes for stormwater management

Previous Image 1/2 Next Image

Arlington County is poised to purchase two additional homes for stormwater management in the Waverly Hills neighborhood.

The pair of homes are a few doors down from the first home it purchased last month on 18th Street N.

The county will pay $1 million for the home at 4423 18th Street N. and $1.3 million for the other at 4433 18th Street N., per county reports prepared for each sale contract. The Arlington County Board is set to review these contracts during its meeting on Saturday.

The two will be torn down for $350,000 apiece and the land will be replanted to create green spaces that will act as overland relief — essentially a safe pathway for water to flow during large flooding events, such as the floods of July 2019. Such flooding events have particularly impacted the Spout Run watershed, where the county is targeting its land acquisition efforts.

Neither home has a historic designation nor architectural significance but staff from the county’s Historic Preservation Program recommend that viable parts of the home be salvaged and photos taken of the interior and exterior for the program’s archives.

Sales are expected to be settled in about five months and the residents will have two months beyond that to move out.

Arlington County previously told residents of the Waverly Hills and Cherrydale neighborhoods it is considering several stormwater management strategies but voluntary property acquisition will be “necessary” for reducing flood risk.

At the time, it said it would first focus its efforts on the Waverly Hills neighborhood and touted benefits of selling to the county such as lower closing costs and peace of mind.
