Arlington, VA

In the midst of Arlington’s efforts to protect local streams, the county last week released an extensive guide debunking what it says are common stream restoration “myths,” touching on everything from ecology to rain gardens.

The following six “myths” were challenged by the county:

  • #1: If Arlington County did proper maintenance on the streams, we wouldn’t need to do stream restoration.
  •  #2: If Arlington County regulated infill development more, the streams wouldn’t be in such bad shape.
  • #3: More rain gardens and trees in the watershed could restore the streams without having to reconstruct the stream channel.
  • #4: Stream restoration makes stream habitat and stream ecology worse.
  • #5: Streams should never overtop their banks. After stream restoration, stream flow should be significantly less.
  • #6: The July 8, 2019 storm showed that stream restoration projects cannot handle intense storms or climate change.

When storms occur and water builds in steams, the resulting erosion can cause health issues for water-based wildlife and create infrastructure challenges. In order to prevent erosion, restoration alters the stream’s direction and adds step-pool structures to slow water flow, the county said.

County officials argue that restored stream sections of Donaldson Run, Windy Run, and Four Mile Run kept the channels from eroding during the summer storm. On the other hand, “unrestored sections of Donaldson Run did not fare well during the July 8 storm, with new erosion undermining the fence and trail.”

Arlington’s stream restoration projects aren’t without its critics, especially when it comes to the touchy subject of tree removal in Myth #3.

In an email sent to ARLnow, Suzanne Sundburg, a local environmental activist and member of the Arlington Tree Action Group, argues the opposite — “planting trees… ABSOLUTELY DOES reduce the stormwater runoff,” she wrote.

“These stream restoration projects, as implemented in Arlington County, use heavy equipment that involves significant tree loss in the very riparian areas that are supposed to be protected from tree loss and development,” said Sundburg.

Sundburg argued that development has damaged local streams.

“Maintenance of our streams and their banks isn’t the issue and thus stream ‘restoration’ is not the solution,” she wrote. “The underlying cause of urban stream syndrome is the increasing volume and speed of runoff coming from the watershed. Unless and until the county begins to correct and reverse the increase in impervious surfaces — now covering 45% of the county’s land surface — stream restoration is impossible.”

Local advocacy groups have previously sounded off against tree removal, namely in 2017 when local residents launched a petition against the removal of 70 trees in Donaldson Run.

Currently, the county is in the design phase of its Gulf Branch Stream Restoration project, which is intended to protect the waterway and the trees along its banks.

A Gulf Branch-specific “Myths and Misconceptions” was presented during a November 6 community meeting on the project. In the presentation, officials addressed the effects of the July 8 storm on the stream, noting the “unrestored stream segmented eroded tons of sediment, degrading and stressing habitat downstream.”

Arlington’s Department of Parks and Recreation is hosting a campfire series for families, staring this week.

The series starts this Saturday, September 7, at Gulf Branch Nature Center (3608 Military Road) from 6-7 p.m. and offers attendees campfire stories, games, and s’mores.

The theme of this Saturday’s fire is “Nice Mice,” followed by an “Insect Chorus” event next Saturday 14 at the Long Branch Nature Center (625 S. Carlin Springs Road) from 7-8 p.m.

“The whole family is invited to join in our campfires, for lots of old fashioned fun,” wrote organizers on the event’s website. “You’ll hear campfire stories, may meet some animal guests, play games, sing songs and, of course, enjoy s’mores! Each campfire has a nature theme and promises to entertain.”

The series alternates on Saturdays between Gulf Branch and Long Branch until November 23, and each event costs $5 per person.

The county has hosted single-event campfires before, celebrating the Solstice in 2016, New Year’s Eve in 2011, and Memorial Day in 2010.

Arlington will host an all-things-bat event later this month for families looking to learn more about the nocturnal mammals.

Next Saturday, August 24, people can check out the festival at the Gulf Branch Nature Center (3608 Military Road) from 6:30-9 p.m. The event will include a live bat show as well as games, crafts, and a walk to teach participants more about bat habitats.

The bat shows are led by Leslie Sturges, who runs the Save Lucy Campaign conservation program. Sturges is a former Smithsonian zookeeper who founded a Virginia bat rescue center called Bat World NOVA.

Sturges also wrote a book called “Lucy’s Story,” which follows the life of an imaginary little brown bat named Lucy as bats nationwide struggle with a deadly fungus that’s decimating many bat populations.

Animal Control Chief Jennifer Toussaint previously told ARLnow that the epidemic has hit the county hard, and asked residents’ help in saving any of the remaining ones.

“Eight years ago as an officer I would periodically bring in little brown bats,” she said. “I haven’t seen one in about two years.”

Organizers for the Arlington festival wrote in the Facebook event description that the event is a chance, “enjoy a thoroughly batty evening and add to your knowledge of local night life.”

Registration is required for the festival, and costs $5. Anyone interested in attending can sign up on the county’s website, or by calling the Nature Center at 703-228-3403.

Officials are asking for the public’s feedback on a plan to stem the tide of erosion plaguing one local stream.

Residents can fill out an online survey to share their thoughts on the Gulf Branch Stream Restoration project this summer as the county officials work to prepare designs for protecting the waterway and the trees that call its banks home.

The stream faces problems stemming from the increasing amount water flowing down its channel due to stormwater runoff. This causes the stream to eat away at the banks, which exposes roots and pipes, and carries sediment downstream, according to Watershed Outreach Program Manager Aileen Winquist.

“Restoration projects actually are trying to create a stream channel that’s stable for the long term,” she told ARLnow yesterday (Tuesday.) “So we’re designing a new stream channel that will help the stream water dissipate energy as it flows down, so it’s not doing as much damage.”

Officials are planning to change the way the stream curves and add step-pool structures to slow the water flow. The work will be similar to measures county crews previously took to restore the Donaldson Run stream.

Winquist says reducing erosion along waterways like Donaldson or Gulf Branch is critical because when too much dirt is carved out of the banks it can cause health problems for fish and other water-based wildlife. Sediment siphoned downstream can also cloud the surface of the Chesapeake Bay, preventing sunlight from reaching the watergrasses that shelter crabs, filter water, and feed aquatic creatures.

In the case of flash floods, algae can also bloom which strips the oxygen from the water, killing aquatic life. Chemical pollution can have the same effect — as the Gulf Branch stream experienced in 2012.

Because of this, Virginia requires local jurisdictions to lower sediment pollution levels. Arlington pledged to reduce pollution levels in 2012 by 5% in 2018, and enacted programs and ordinances to reduce the amount of stormwater runoff and pollution.

Stream erosion also causes infrastructure challenges, Winquist said. Because many of the county’s older sewer lines from the 1950s rely on gravity they run under stream valleys. As a consequence, recent floods damaged pipes like the one under Lubber Run, which in turn swallowed the stream.

“When first installed, they were installed several feet down,” Winquist said. “But as as the stream erodes down over time, they become exposed.”

A pipe under Gulf Branch was encased in concrete to prevent damage from exposure — but now the concrete is crumbling.

Winquist noted that in the past, some residents have expressed concerns over trees that need to be felled as part of the process. She said the county replants at least one tree for each one cut and asserted that not performing the work would allow the erosion to continue and would be a greater threat to the local environment.

“It’s not a great condition to leave the stream in,” she said.

The county expects to hold a public meeting in the fall and will continue discussing restoration designs into the new year. Winquest said it will likely be “a couple of years” before construction starts.

Why did the salamander cross the road? To get to the vernal pool breeding grounds, of course.

Most people wouldn’t laugh at that, but the joke might have killed at Thursday’s salamander patrol training session at Arlington’s Long Branch Nature Center.

The nature center holds yearly salamander training sessions to educate volunteers on the dangers that salamanders and other vernal-pool-dwelling amphibians face during the annual migration.

Amphibians generally live in ponds but some, like the spotted salamander or wood frog, only live in vernal pools — watering holes that dry up in the fall. These are ideal spots for the critters to thrive in, because predators like fish and other amphibians prefer year-round pools.

But because only two or three vernal pools remain in the increasingly urbanized county, hundreds of salamanders and wood frogs have no choice but to cross the pool-adjacent driveways and sidewalks, according to Jennifer Soles, an Arlington County naturalist and long-time Arlington resident.

Soles began the salamander squad program in 2013 after attending a master naturalist training the year prior. As Long Branch Nature Center volunteers were leaving the class, salamanders and frogs began their breeding ground migration — across the parking lot, and under a lot of car tires.

“They’re all there because they love nature and it’s their master naturalist training,” said Soles. “And everyone is running over the frogs and salamanders.”

Soles grabbed a flashlight and began escorting the unhurried salamanders off of the pavement, joined by other horrified naturalists.

Arlington’s naturalists have since tried to prevent further amphibian annihilation through the salamander training sessions. At the Feb. 8 training session, at least 16 community members learned how to protect their local croakers from another Arlington County naturalist, Rachael Tolman.

The session focused on frog and salamander biology and breeding habits, and taught volunteers safe handling practices. Tolman walked volunteers through filling out scientific forms that allow on-site naturalists to predict travel patterns.

“If it’s a little squish, it’s a [spring] peeper, if it’s a medium squish, it’s a wood frog,” said Tolman, explaining how to fill out the alive-or-dead count portion of the form for the rundown animals. “If it’s kind of a spotted, long squish, it’s probably a spotted salamander.”

A salamander patrolman is nothing without his or her tool kit, which includes a reflective vest, headlamps, pens — and a garden spade for scraping squished salamanders off of the road.

While the event was intended to be for ages 13 or older, few teenagers were in attendance. Most volunteers were much older with a more developed environmental interest.

Peter Hansen, a Federal Reserve Board researcher, is a 24-year-old Arlington resident and one of the county’s master naturalists.

“I saw the email blast about the salamander patrol, and it sounded really hype,” said Hansen, noting that several of his friends are nature enthusiasts that he admires for their vast knowledge of the environment.

“I can add a lot of color to my experience in nature,” said Hansen. Most likely, he’ll be returning to serve on the salamander squad.

Tuesday’s heavy rains caused some flooding around Arlington, especially in the northern reaches of the county.

An overflowing storm drain brought elevated water levels to the intersection of Military Road and 35th Street N., where drivers had to contend with significant standing water following a slug of heavy rain this morning. Police were on scene, but there were no road closures.

An earlier report suggested higher, more hazardous water levels along Military Road while the rain was still falling.

Other areas of reported flooding included the area of Glebe Road and Chain Bridge and the intersection of Yorktown Blvd and N. Harrison Street — though no standing water was observed there when an ARLnow.com reporter drove by.

The National Weather Service warned earlier today about flash floods in the region, with the threat running through early afternoon. The heavy rain that brought flooding to Arlington appeared to bring more severe conditions to Northwest D.C., where residents posted photos and videos (below) of roads turned into fast-moving streams.

Arlington’s Dept. of Public Safety Communications & Emergency Management, meanwhile, reminded residents to “turn around and don’t drown” when encountering flooded roadways.
