Sponsored by Monday Properties and written by ARLnow.com, Startup Monday is a weekly column that profiles Arlington-based startups and their founders, plus other local technology happenings. The Ground Floor, Monday’s office space for young companies in Rosslyn, is now open. The Metro-accessible space features a 5,000-square-foot common area that includes a kitchen, lounge area, collaborative meeting spaces, and a stage for formal presentations.
Starting in late April, cat and dog owners can track their pets and find animal-friendly places to eat and stay in one place.
Set to hit major app stores next month, Roaming Tails will provide one platform for all pet owners’ biggest needs. Ballston resident Jaime Bowerman founded the company in 2014, inspired by Flipflop, her Daschund.
“In talking to many other pet parents, they seemed to have similar sorts of problems, and there’s really no good place to find accurate data that tells us where we can take our pets,” Bowerman said. “She also had a mind of her own like most dogs do, and there had been a time where I thought she was missing, which was kind of scary.”
Pets are connected to their owners through a tag around their neck, which connects to the app via Bluetooth. That tag then integrates with the app to provide medical records, and has a long battery life of upwards of a year.
And while the Bluetooth capabilities limit the range of separation between an owner and their pet to about 50 yards, Bowerman said there has progress on that front.
In January, company employees attended the International Consumer Electronics Show in Las Vegas and agreed to partner with a major tag provider to have tags that use Wi-Fi as well as Bluetooth.
Bowerman said that combined with the Ballston Business Improvement District’s initiative to deliver free wi-fi in the neighborhood’s public spaces can help grow the product’s use.
“What we’re really hoping to do on launch in early April is to make [Ballston] the most pet-friendly place possible that we can,” she said. “It’s pretty exciting technology.”
With the launch a matter of weeks away, Bowerman said she and her colleagues are working to get the app as perfect as possible by testing it among themselves. But with hopes of partnerships with pet stores and veterinarians, they have grand ambitions.
Roaming Tails also could be at the forefront of partnerships with local pet-friendly restaurants, Bowerman said.
“Let’s say you’re walking past a restaurant with our tag, what happens is your phone will bark at you and say, ‘Bring Fido in for two-for-one drinks,'” she said. “It really is a way for restaurants to easily market to people with pets and to easily set up rewards programs and things like that.”
Bowerman said with the way the relationship is evolving between pets and their owners, this app can fill a valuable need in one place.
“Technology is changing the way we life live with our pets, but unfortunately it just takes a lot of apps to enhance the quality of life or change that,” she said. “What we have done is taken most features and put them on one platform that allows you to do these things.”
A Baltimore-based fast casual noodle bar will arrive next year at the redeveloped Ballston Quarter mall.
With locations already open in the Federal Hill and Mount Vernon neighborhoods of Baltimore and another set for Hampden in September, owner Edward Kim said he expects the new spot in Arlington to continue the success he’s found in Charm City.
“The deal is right, I think the area is really good,” Kim said. “It’s very dense with good foot traffic, energy and good demographics.”
Kim said Mi and Yu is different from other Asian eateries, as customers can build their own noodle bowls, choosing from a variety of broths, noodles and proteins. The menu of Chinese steam bun sandwiches — known as bao — is extensive too, and customers can again customize.
“It’s basically a build your own concept, like you would do at Panera Bread or Chipotle,” Kim said. “It’s definitely not a traditional place.”
After a brawl earlier this month outside A-Town Bar & Grill in which two men were tased by police, the bar will be subject to stricter county reviews.
The County Board approved a plan Tuesday for staff to review the bar’s permit for live entertainment and dancing in one month, then have the Board review it again in three months. Previously, the permit was up for Board review every six months.
Co-owner Mike Cordero said the two suspects — one of whom was dressed as Pikachu, according to police — were A-Town customers, but had been cut off and escorted out. Cordero said the incident took place two hours after they left, and not on their property.
Board members agreed A-Town must work with the county to fix the problems being caused by unruly patrons.
“I think what we have to come to grips with, regardless of whether you want to take responsibility or not, there’s a problem with this establishment in terms of what happens with the patrons when they leave, and what they do to the wider community,” Board member Christian Dorsey said.
A staff report found police responded to A-Town 38 times between September 20, 2016 and March 17, 2017. Board chairman Jay Fisette said the quantity of calls is less important than their content.
“The number doesn’t mean anything,” Fisette said. “It’s the nature of the call, and what can be prevented and what cannot be prevented.”
But neighbors of the bar in Ballston bemoaned the behavior of some of its patrons after they leave. Many incidents take place during A-Town’s popular “Sunday Funday” festivities.
“Enough is enough of this [neighborhood] degradation,” said Theodore Gebhard, a member of the Altavista/Berkeley Ad Hoc Committee of Concerned Homeowners. “It needs to be addressed by the county.”
Lee Austin, a resident at the Altavista condo building, decried an “irresponsible business model” where people who are already drunk are still served alcohol. He also read an email from a neighbor recounting who witnessed “egregious sexual behavior” on the patio, behavior he said is damaging to the neighborhood.
A meeting will be held tonight between A-Town management and Arlington police to discuss the brawl from earlier this month. Further discussions will be had with the fire marshal and Virginia Alcoholic Beverage Control officers.

(Updated at 1:35 p.m.) After staying open for months on borrowed time, Ballston bar CarPool is preparing to close for good.
The popular local watering hole will serve its last customers in Ballston on Monday, April 3, says co-owner Mark Handwerger.
The announcement, below, comes seven-and-a-half months after the first reports that CarPool was about to close after it was sold to make way for a large redevelopment. That development was approved in 2015 but subsequently delayed.
More on the “closing night” plans from CarPool’s management:
Please join us on Monday, April 3rd, for Closing Night. It should be a grand day as we simultaneously celebrate Baseball’s Opening Day (and the start of the Nationals pursuit of a World Series crown), the culmination of another wonderful and wacky March Madness (and the crowning of this year’s NCAA Men’s Basketball Champion: UCLA?!?!), and one final Last Call for CarPool. Please stop in and say “goodbye” one last time before the taps run dry.
Handwerger says the owners of CarPool expect to open a new location in the Fair Lakes area of Fairfax County as early as July or August.
A busy street in Ballston will be closed this weekend while crews work to erect a construction crane.
N. Randolph Street is set to be blocked off between Wilson Blvd and the Ballston mall parking garage starting at 9 a.m. Saturday. The massive crane will be assisting with the construction of the new residential tower, which is part of the Ballston Quarter project.
More from the Ballston BID:
Clark Construction Group and their subcontractors will be erecting the tower crane for the Ballston Quarter Residential Tower this weekend on Saturday (3/18) and Sunday (3/19).
They will be closing N. Randolph Street between Wilson Blvd. and the Arlington County Parking Garage starting Saturday, 3/18, at 9 AM. and will be reopened upon completion. Vehicles will be detoured from N. Randolph St. for the entire duration of the closure. (Note: The County parking garage entrance on N. Randolph St. will remain open.) You will find a diagram of this condition for your above.
Off-duty police officers will be present to help enforce the closures and field and questions.
(Updated at 2:20 p.m.) A new pedestrian walk light at a dangerous intersection could help ease safety concerns for those on foot.
A teen was struck by a car last year at the intersection of Washington Boulevard and N. Utah Street near Washington-Lee High School and suffered a serious head injury.
In the aftermath, Arlington County police conducted a pedestrian safety detail at the intersection to enforce traffic laws on scofflaw drivers. Still, reports of drivers ignoring pedestrians in the crosswalk continued.
As of last week, however, the county has installed new high-visibility walk signs and lights at the crossing to help pedestrians and bicyclists cross Washington Boulevard.
After pressing a button, the lights flash for approximately 10 seconds to warn drivers that people are crossing. An audio message tells crossers that the lights are flashing too.
And while the signals do not include stoplights for drivers, several did stop as required on Monday afternoon to let pedestrians cross while an ARLnow.com reporter was taking photos.
(Updated at 4 p.m.) A wild fight outside Ballston’s A-Town Bar & Grill last night resulted in two suspects being tased by police, including one man who was brawling while wearing a Pikachu onesie.
The incident happened around 9 p.m. on the 1000 block of N. Randolph Street. According to police, it started when the man in the Pikachu costume, Steven Goodwine, Jr., tried to pick a fight with the bouncers at A-Town after being kicked out of the bar’s weekly “Sunday Funday” festivities.
Goodwine “became aggressive with the door staff and Mr. Reid attempted to intervene,” according to what may be the longest item ever on an Arlington County Police Department daily crime report (below).
Police arrived and tried to break up the fight between Goodwine and Reid, according to the crime report. The men allegedly stopped fighting with each other and started fighting with police. Both suspects were tased during the fracas and Goodwine tried to flee, but both were eventually taken into custody and no one was seriously injured, police say.
More from the ACPD crime report:
ASSAULT & BATTERY ON POLICE, 2017-03120191, 1000 block of N. Randolph Street. At approximately 8:58 p.m. on March 12, police were dispatched to the report of a fight in progress. The arriving officer located the subjects, later identified as Steven Goodwine Jr. and Marcus Reid, and provided verbal commands to cease the fight. The subjects allegedly ignored the commands and the officer physically separated them. As the officer was attempting to detain Mr. Goodwine, Mr. Reid advanced and struck the officer, pushing him to the ground. When Mr. Reid advanced towards the officer a second time, the officer deployed his taser. As officers were attempting to place handcuffs on Mr. Reid, he continued to forcefully resist while attempting to stand. An officer deployed their taser and the subject was taken into custody without further incident.
Additional officers responded to Mr. Goodwine’s location who was attempting to flee the scene. Officers ordered the subject to stop and get on the ground. When he refused, officers went hands on in an attempt to detain the subject. Mr. Goodwine struggled with the officer and was able to place him in a stranglehold. The officer was able to free himself, deploy his taser and the subject was taken into custody without further incident. Both subjects were evaluated by medics and did not sustain serious injuries. The investigation revealed that the initial incident began after Mr. Goodwine was removed from a restaurant, became aggressive with the door staff and Mr. Reid attempted to intervene.
Marcus Reid, 31, of Arlington VA was arrested and charged with assault and battery on police, obstruction of justice and drunk in public. Steven Goodwine Jr., 27, or Arlington VA was arrested and charged with assault and battery on police, strangulation, disorderly conduct, obstruction of justice and drunk in public. Both were held in the Arlington County Detention Facility on No Bond.
CORRECTION: An earlier version of the crime report interchanged the subjects names in the first paragraph. The report has been corrected at approximately 3:00 P.M. on March 13, 2017.
With the National Science Foundation moving out of Ballston this year, its current building is slated for renovations.
The NSF will relocate to Alexandria, starting no later than September 1, and leave its present headquarters at Stafford Place on Wilson Boulevard.
And with its federal tenant on the way out, property owner Jamestown LP is looking ahead to the future of its buildings, which it bought for a combined $300 million in 2015.
The two buildings will be renamed the Ballston Exchange, with the 12-story atrium in 4201 Wilson Blvd set for a revamp in addition to new electronic systems and elevators and new tenants for the upper and lower levels.
All told, the renovation work will cost approximately $140 million, and will include new retail space on the ground floor.
Michael Phillips, president of Jamestown, said the firm is looking to take advantage of the growth in high-tech and cybersecurity jobs in Northern Virginia when searching for new tenants.
“We have specialties in internet security and in technology around that sort of process, but we also have the associations and the lobbying groups and the private industry that have all started to make Northern Virginia home,” he said. “To provide an environment for that for both small companies to incubate ideas and large companies to be part of the campus is our goal.”
To attract those tenants, Phillips said, Jamestown will make sure the renovated space embraces the new “interactive culture” of the workplace. Phillips said the redone space will include an interactive conference center and communal spaces, as well as amenities like yoga and spin classes to help with employees’ health and wellbeing.
And despite the departure of a federal tenant and the departure of more than 2,000 NSF employees, Phillips said Jamestown relishes the opportunity to revamp its property given the apparent region-wide trend away from government work.
“We bought the building knowing they [the NSF] were going, with the intent to do what we’re doing,” Phillips said. “I think there was a time that submarket was a very high percentage of government contractors and agencies, and I think that is shrinking and being replaced by private sector companies.”
Phillips said the renovation should be complete by next spring or summer, given that it will not begin until the NSF vacates.
Helen Duong, spokeswoman for the county’s Department of Community Planning, Housing and Development, said the last permit application submitted for the NSF property was last August to remove the existing sky bridge.
Arlington Economic Development spokeswoman Cara O’Donnell said the organization is looking forward to seeing what Jamestown will do.
“We’re excited about the significant new investment Jamestown is making that will deliver high quality Class A office space as well as new ground floor retail frontage in the heart of Ballston,” she said. “Additionally, this ideally-located property is located just across the street from the new Ballston Quarter public-private redevelopment.”
The redevelopment of Ballston Common Mall across the street — and its rebranding as Ballston Quarter — means there is plenty going on in that part of the county.
Demolition of portions of the mall to make way for the new apartment tower and retail center began last year.
BLinked is available throughout Ballston’s public areas, thanks to a partnership between the Ballston Business Improvement District and Rockville-based startup Wi-Fiber. The BID says it is the first seamless, district-wide network in the region.
Wi-Fiber developed a system to serve the more than 30,000 people that work in Ballston. More than 30 discreet antennae relay signals connect all of Ballston’s outdoor public spaces to the “gigabit-capable” network, according to a press release.
Using algorithms to track data usage patterns throughout the neighborhood, BLinked also reads and interprets network activity in real time. It then uses the gathered data to redistribute resources to meet traffic and usage demands, meaning that users should not experience slow-downs.
“This is the next step in making Ballston stronger, smarter, and safer,” said Tina Leone, CEO of the Ballston BID. “We’re proud to be the first to meet the impending need for public connectivity, and we anticipate this inspires new information and communication infrastructures throughout Arlington and across the region.”
Such programs have been requested by local business leaders, including Monumental Sports & Entertainment chairman Ted Leonsis in an interview with the Washington Business Journal last month.
A similar initiative has been undertaken in New York City through LinkNYC, which has worked to replace pay phones in the city with so-called “Links,” which provide services like high-speed Wi-Fi, phone calls, a tablet for maps and city services and charging outlets.
The new Wi-Fi network can help reduce strain on traditional cellular networks, which can crumble under heightened activity in crisis situations.
Chase Donnelly, a founding partner of Wi-Fiber, said the move to area-wide Wi-Fi can help integrate electric grids, water systems, stoplights and more into the Internet system to improve efficiency.
“This network could one day serve as the spinal cord for the city’s infrastructure,” Donnelly said in a statement. “This vision people have about the next generation of cities in which everything is interconnected, that’s what we’re providing the foundation for.”
Update at 3 p.m. — A PR rep for the BID clarified that the network is “gigabit-capable,” not “gigabyte-capable” as stated in the press release. The network is currently being tested and is expected to be available to the public by the end of the month.
One of the incidents happened early Friday morning in Ballston, while the other happened last Tuesday along Columbia Pike.
ASSAULT & BATTERY ON POLICE, 2017-03030034, 4000 block of Wilson Boulevard. At approximately 3:01 AM on March 3, police responded to the report of a dispute. As officers were conducting the investigation, a male subject became aggressive and pushed an officer several times before being detained. A warrant was secured for Assault and Battery on Police for Robert Holloway, 46, of Arlington VA.
ASSAULT AND BATTERY ON POLICE, 2017-02280024, 5500 block of Columbia Pike. At approximately 2:50 a.m. on February 28, officers responded to the report of a fight in progress. As officers were investigating the incident, a subject on scene became argumentative and aggressive towards an individual being interviewed by police. As officers were attempting to escort the subject away from the scene, he allegedly began to physically resist the officers, swung his arm and struck an officer in the face. Dorj Jargalsaikhan, 47, of Arlington VA was arrested and charged with Assault and Battery on a Law Enforcement Officer. He was held on no bond.

A local man will spend 25 years in prison for sexually assaulting a woman after breaking into her apartment last year.
Arlington resident Anibal Rodriguez Castellanos was today sentenced to 30 years, with five years suspended, for a charge of burglary while armed and 10 years for a charge of attempted rape. The sentences will run concurrently.
Police said Castellanos, 37, broke into an apartment on the 3900 block of 4th Street N. and sexually assaulted a 28-year-old woman who lived there on June 19 last year.
More from ACPD:
An Arlington man was sentenced on Friday, March 3, 2017 in the Arlington County Circuit Court for his role in a 2016 sexual assault. Anibal Rodriguez Castellanos, 37, was sentenced to thirty years, with five years suspended, for the charge of burglary while armed and ten years for the charge of attempted rape. These sentences will run concurrently. After his release, Castellanos will be listed on the sex offender registry and will be deported upon serving his sentence.
Theophani K. Stamos, Arlington County Commonwealth’s Attorney and M. Jay Farr, Arlington County’s Chief of Police made the announcement following the court appearance.
At approximately 2:00 a.m. on June 19, 2016, a male subject unlawfully entered a female victim’s residence in the 3900 block of 4th Street N. and sexually assaulted her. The subject used the threat of a weapon to hold her against her will. During the attack, the 28-year-old female victim was able to lock herself in the bathroom and yell for help. The male subject fled the scene on foot and was observed by a neighbor leaving the scene.
Following interviews with the victim and witnesses, a composite sketch of the suspect was developed. A combination of evidence collected during the investigation and the accounts of several people from the neighborhood led to the identification of Anibal Rodriguez Castellanos.
“The victim’s searing courtroom testimony today was heartbreaking and the sentence handed down today by Judge Newman was entirely appropriate. My hope is that today’s outcome will bring a small measure of peace and closure to the victim. She deserves that.” Theo Stamos, Commonwealth’s Attorney.
Arlington County Deputy Chief Daniel J. Murray, Commander of the Criminal Investigations Division said, “The steadfast investigative work completed by our detectives, the strong partnership with the Arlington County Commonwealth’s Attorney’s Office and the ultimate sentence imposed by the court sends a powerful message that we will use all available resources in our pursuit to keep our community protected from sexual predators.”
Detective P. Pena was the lead detective and the case was prosecuted by Commonwealth Attorney Lisa Tingle.
(Updated 4:55 p.m.) A plan to redevelop a Ballston church and preserve its historic graveyard got the go-ahead Tuesday night from the Arlington County Board.
The board unanimously agreed to revamp the Central United Methodist Church at 4201 N. Fairfax Drive to be an eight-story apartment building and two levels of underground parking.
Also on the site is the Robert Ball Sr. Family Burial Ground, which has now been designated as a local historic district. The first burial on the site took place in 1854, then was deeded to the church in 1906.
Given the site’s history, there had been concerns previously that construction on the site would disturb some of the remains of those buried in the cemetery.
Residents urged the developer behind the project not to move the graveyard last October. Members of the Ball family previously said that, although they did not want to prevent the redevelopment of the church, they wanted the church to honor its century-old commitment to preserve the graveyard.
Attorney Tad Lunger, representing the project’s nonprofit developer, said crews will investigate thoroughly where remains might lie.
Lunger also said an archaeological team has been on staff since the beginning of the project, and that they will be on site alongside county staffers and representatives of the Ball family if any remains or other objects are found.
Lunger said any remains discovered will be exhumed, sent to Towson University for biological analysis, then re-interred. He said that process would help clear up the “unknown history of this site.”
The first two floors of the building will include a daycare facility for 100 children and a church to seat 200 people.
On the upper floors, 119 apartments will be built, of which 48 will be designated as affordable units for 60 years. The affordable units will be financed by a $3.1 million loan from the Affordable Housing Investment Fund, while the project will apply for low-income housing tax credits from the Virginia Housing Development Authority.
“I applaud the leadership and membership of this church for bringing forward this creative project that addresses, on one site, many needs of our Ballston neighborhood,” said county board chairman Jay Fisette. “While preserving an important historic site for Arlington, we will simultaneously provide new, affordable housing, church space and child care services for years to come.”
Before the board’s unanimous approval, members and local residents alike raised concerns about the parking available at the site. A total of 128 spaces will be provided across the two levels of underground parking, with 119 for the residential units and nine for the church and daycare.
(Updated at 2 p.m.) Arlington County Police have arrested a man suspected of robbing a bank in Ballston last month.
Someone dressed in a winter coat and sunglasses walked into the Navy Federal Credit Union at 875 N. Randolph Street on Feb. 10 and passed a note to a teller before running off with an “undisclosed amount of cash,” police said.
ACPD — with the help of the FBI, the Alexandria Police Department, Falls Church City Police Department, Fairfax City Police Department, Fairfax County Police Department and the Prince William County Police Department — arrested 32-year-old Christopher Alan Martin in connection with the robbery yesterday around 5 p.m.
Authorities believe Martin may have also robbed a Navy Federal in Potomac Yard and then dumped some of the loot on S. Glebe Road in Arlington the same week. Alexandria police have not yet charged Martin with a crime, however.
From an ACPD press release:
The Arlington County Police Department has arrested and charged a suspect for his involvement in a bank robbery at the Navy Federal Credit Union located at 875 N. Randolph Street. Christopher Alan Martin, 32, of No Fixed Address was arrested at approximately 5:02 p.m. on February 28, 2017 as he returned to a residence in the 700 block of S. Monroe Street.
Martin has been charged with bank robbery and is being held on no bond in the Arlington County Detention Facility.
On Friday, February 10, 2017, at approximately 11:40 a.m., a male subject entered the Navy Federal Credit Union located at 875 N. Randolph Street in Arlington, Virginia and passed the teller a note, demanding money. The suspect fled the scene on foot with an undisclosed amount of cash. The suspect did not imply or display a weapon.
The suspect was apprehended with the assistance of the Federal Bureau of Investigation, Alexandria Police Department, Falls Church City Police Department, Fairfax City Police Department, Fairfax County Police Department and the Prince William County Police Department.

Carpool Bartender Profiled — “In an era where craft cocktails, celebrity chefs and ‘artisanal’ everything dominate the D.C. dining scene, it’s hard to find a watering hole where comfort comes in the form of a bottle of Bud, a basket of onion rings and a bartender who knows your name. But at Carpool in Arlington, Virginia, that is exactly what’s on the menu — at least for a few more weeks.” [WTOP]
County Board Pay Raise Proposed — The Arlington County Board this weekend will consider a proposal to raise its own pay by 3.5 percent. That would bring the salary for the County Board chairman to $56,628 and the salary for County Board members to $51,480. [Arlington County]
