Posts about Security
If you refuse a bag search at a WMATA subway station, Metro Transit Police may follow you if you leave and even if you board a bus. That's what happened to me Tuesday morning in Shaw.
I entered the Shaw Metro station with a bag containing my lunch and my laptop. An officer waved me aside on the north mezzanine and told me to put my bag on the table for inspection. Stunned that I was being stopped without cause, I asked the officer if he had a warrant. He said that if I refused, I was "welcome to use another mode of transportation."
I refused the search, which is mostly about theatrics than actual security. I didn't want to enable what critics have labeled "security theater", the symbolic show of force to give the appearance of protection. In fact, WMATA admits that since they don't search every bag, it's really more about perception, providing "an additional visible layer of protection." Putting on a show is not a good reason to rummage through people's personal items and I didn't want to enable that behavior and belief.
By agreeing to an "optional" WMATA search, I was afraid I would also be inadvertently consenting to a search of my laptop, which would be an abusive and unreasonable intrusion for a transit agency. I wasn't sure if the officers were properly trained to know the nuances of what was and wasn't an appropriate search. How would you even argue with an officer who believes random bag checks at one station actually deter terrorism, anyway? It's like arguing the plot in a fiction novel: the very premise is that facts only partly matter.
Remembering reports that Metro Transit Police only set up searches at one entrance, I pointed to the south mezzanine and said, "I can use that entrance," and the officer said nothing. I left the north entrance to walk to the south entrance a block away.
As I descended the escalators to the south mezzanine, I spotted more officers in the distance. Realizing that the answer would probably be the same at this entrance. I calmly turned around and left, deciding to catch the bus instead.
Little did I know that Metro Transit Police would follow me there. I boarded the 70 bus, which runs above the Green and Yellow lines on 7th Street NW and SW. Two officers got on behind me. Their vests were marked with the word "Terrorism" (perhaps, "Anti-Terrorism" or "Counter-Terrorism", I don't remember which), so clearly they were not there to investigate a fist fight, theft, or fare evasion.
One officer took a seat and another stood, mostly watching his phone. Neither of them said anything to me.
Perhaps it was a coincidence, I thought. Why would police follow me for refusing a supposedly "optional" search, even after I was told I was "welcome to use another mode of transportation"? I was on another mode, after all.
When the bus reached H Street, where I intended to transfer to the Red Line, I paused a moment in my seat, to see what the officers were doing. They remained on the bus. I then got up and stood in line to leave the front of the bus. As I neared the front door, I looked back and noticed that one of the officers had left the back door of the bus and was standing outside.
To test if he was following me, I then sat down in a seat at the front of the bus, and the officer re-boarded the bus through the back door. The driver closed the doors and I asked her if she could reopen it so I could leave. She pushed the door mechanism, which reopened the front and the back door and I left the bus.
As I left the bus at the front door, the officer standing at the back door, partly hanging out the bus, waved and smiled at me through the glass of the rear open door. This act was about sending me a message: if you refuse a search, you will be followed, which is itself a form of intimidation.
WMATA's stated policy allows customers to refuse the allegedly optional search. "Customers who encounter a baggage checkpoint at a station entrance may choose not to enter the station if they would prefer not to submit their carry-ons for inspection," it says.
While you may be "welcome to use another mode of transportation," bag searches aren't really optional if Metro Transit Police follow you and deliberately make it known that they're following you.
"Please empty your pockets and put all of your electronic devices on the bin," DC Library Police officers used to tell every patron entering the revolving doors of the Martin Luther King Jr. Memorial Library. The days of passing through a metal detector at the city's central library are long gone.
Under the tenure of Chief Librarian Ginnie Cooper, the library has modernized the 1st floor's Great Hall (originally Peterson Hall) and is creating a "Digital Commons Technology Space."
The library police also have a new perch that resembles a judge's bench. The desk follows the same 1970's style as the original circulation desk, just around the corner.
"Welcome to MLK Library. May I help you?" is now the refrain greeting patrons at the library.
Dulles Airport built two huge security checkpoints in 2009, but somehow it still can take a very long time to get through security, especially at busy times when a lot of international flights are soon to leave. How long does it really take? Now we have some data.
Last August, Dulles installed new systems that estimate the wait time at each checkpoint. Cameras connect to computers which try to judge the wait based on the size of the line and the rate of people clearing the checkpoint. You can view the wait times on the web or a smartphone, and screens at the airport show the estimated times so travelers can pick the shorter line.
I set up a system to automatically capture the wait times every 5 minutes, beginning September 23. It's been running for a little over 6 months now, which gives us a good set of data to analyze.
The west checkpoint is the one on the right when you're facing the terminal. It's closer to Daily Garage 2, and also the exit from customs, and is near the first stop on the shuttle buses. Here are the wait times across the average weekday:
Average wait at the west checkpoint for each 5-minute segment, weekdays.
There are some peaks at busy times of day, like early morning, just before noon, and especially late afternoon (when all of the flights to Europe leave), but it's fairly consistent.
The east checkpoint, however, has far more variation:
Average wait at the east checkpoint for each 5-minute segment, weekdays.
Here, the wait times are very low except right around the peak times. This camera seems to report a minimum time of 2 minutes; even in the middle of the night, when the checkpoint is closed, it shows 2 minutes.
Any ideas why this one varies more? Is the volume of people checking in at United or other counters on that side more uneven than on the airlines with west side counters or passengers re-entering after clearing customs? Does TSA staffing vary more? Does the fact that shuttles drop people off first at the west side drive more, and more even, demand to that side?
What about weekends?
Those are weekdays. Are weekends different? Regional transportation always shows huge differences between weekdays and weekends, like Capital Bikeshare usage data, but airlines run pretty much the same schedule 7 days a week. And, in fact, the pattern is little different except the average wait time is slightly less on weekends:
Average wait at the west checkpoint for each 5-minute segment, weekends.
Average wait at the west checkpoint for each 5-minute segment, weekends.
Which checkpoint is better?
Which checkpoint should you take? The best strategy is to actually look at the monitors, but most likely it will tell you to head east unless it's a peak time, when its lines get long:
Probability the east checkpoint has a longer wait for each 5-minute segment, 4 am-10 pm.
Shaded areas show times the probability exceeds 50%.
How big are the differences? If one is better, is that a strong difference? Especially with the real-time screens, you'd expect a lot of travelers to move toward the checkpoint with the shorter line, but apparently not enough do to keep the two balanced.
Differences in waits between the east checkpoint and west checkpoint per 5-minute segment.
This graph shows the size of the typical differences between the two. The center line is the median difference, and the darker area the middle 50% of times; as in the above chart, east usually has the longer lines during these peaks while west is worse at other times.
Still, there is plenty of time when the difference between the two is quite significant, assuming the equipment is accurate. If you have to fly through Dulles, a perfect symbol of how our nation once built great public works but now barely bothers to keep them up and makes new improvements on the cheap, you'll already have long drives and walks to get to your gate; you might as well minimize the wait in those interminable security lines.
On sunny days, Lafayette Square is filled with people. Tourists snap pictures of the White House behind them. Bicyclists and pedestrians enjoy a space where they, not cars, have the right of way.
Although two-block stretch of Pennsylvania Avenue was closed for security reasons, it has become similar to what the Dutch call a woonerf (plural woonerven, which translates roughly to "living street."
A woonerf is a low-speed street where pedestrians and cyclists have legal priority over drivers. In practice, cars, bikes, and people on foot mix freely. Unlike a standard woonerf, Pennsylvania Avenue doesn't regular drivers, but it has taken on many of the elements of the woonerf. Security needs can also close them at a moment's notice. Therefore, I like to call this a "security woonerf."
Since the mid-1990s, cordoned-off areas have popped up throughout the city. Yet, few of them could be called security woonerven. Could this change?
The two most prominent security woonerven in DC are on the east side of the US Capitol and on Pennsylvania Avenue in front of the White House. In these areas, activity takes place mainly on foot or on a bike.
Although security vehicles operate in those areas, they're parked most of the time, so pedestrians and cyclists essentially have the run these spaces. These two locations are obviously popular with residents and visitors alike. Both are now important hubs in DC's expanding bicycle network and as important activity centers for all manner of activity: tourism, lunch breaks, leisurely strolls, running, you name it.
Following the tragedy at Oklahoma City in 1995, federal planners redesigned facilities to minimize risks to important buildings from motor vehicles. All across the city, barriers went up, starting with jersey barriers, giant planters, and police roadblocks.
Over time, these evolved into permanent hardened perimeters with bollards, sally ports, guard gates, and delta barriers. As much as possible, these elements were planned with an eye toward improving aesthetics, or at least in comparison to original concrete jersey barriers.
While the two security woonerven at the White House and the Capitol are great assets to the city, other cordoned-off areas are not.
The security professionals who planned these facilities gave little consideration to bicycle and pedestrian access. The spaces are attractive for walkers and bikers by default, because of their lack of traffic. However, it often isn't easy to travel into or through the perimeter of these areas.
Another security woonerf is in the works for E Street, south of the White House. As many commenters noted during the design competition, though, cyclists appeared to be an afterthought in most of the submitted proposals.
Often, small tweaks could really improve access into these potentially great spaces. Even Lafayette Square has access issues on the north side at the Madison Place sally-port.
The State Department closed C Street NW and segments of other roads next to their Foggy Bottom headquarters, but they have not replaced the jersey barriers and planters with bollards and other elements more hospitable to bicycle and pedestrian traffic. The House and Senate office buildings have several cordoned streets around them that only admit authorized cars, but the access points are difficult to get through by bike.
Although Union Station has closed off driving access through Columbus Circle for security, the space was subsequently devoted to passenger pick-up and drop-off, making this potential security woonerf very difficult for pedestrians and cyclists. Thankfully, work already underway on the Circle will improve upon current conditions.
Beyond these spaces, there are a number of closed campuses in DC which would greatly benefit from adopting some of the more successful security woonerven designs. Specifically, I'd love to see security woonerven at the Old Soldier's Home, the future Walter Reed development (both the DC and State Department portions), and the Washington Hospital Center.
Areas around the Pentagon, and Joint Base Bolling also have potential if security priorities are better balanced with pedestrian and bike permeability. Universities like Catholic, Georgetown, and Howard you can get through, but it's not obvious or direct. Even at the Arboretum and the Navy Yard, where trails and woonerven already exist, extended hours would vastly improve these spaces.
Regardless of why and how we established these areas, federal and local planners need to recognize their success, and understand their best elements. Then they can adopt those elements into sites that have potential, but aren't quite security woonerven yet.
Are there other places we could have a great security woonerf? Also, can you think of a better term? Whatever you you call them, if streets have to close for security, we would all benefit from making more of them living streets.
Do federal office buildings make their surrounding communities better or worse? Last night, 3 local planning directors discussed how federal buildings can make local areas more lively places to work and live, but how some have had the opposite effect.
The Washington region is unique in the number of federal jobs concentrated in large agencies. These large offices have the power to bring new life into neighborhoods and generate new urban growth around existing transit options. But security concerns can derail their positive effects on neighborhoods.
The key to success for these projects is adaptability. "There's no formula. Each project is unique," said Faroll Hamer, Director of Planning and Zoning for the City of Alexandria, at the panel, sponsored by the National Capital Planning Commission.
"The first iteration is almost always horrible," said Harriet Tregoning, DC's planning director. Tregoning argued that communities need to be constantly vigilant and to push back through review and input.
An example of a federal building with negative impact is the FBI Building in downtown Washington. When asked if they thought it was "the worst building in DC," a significant portion of the audience raised their hands. Foreboding and removed from the street, this building serves as an example of what not to do.
On the other hand, the sheer number of workers a new federal office brings into an area can activate the neighborhood. This activity can spur more growth and create new urban fabric where there previously was none. They can give birth to entirely new neighborhoods, or revive ones long since written off.
Qualities of many federal facilities pose problems
Federal office buildings are inherently single-use. Office workers do little for neighborhoods after business hours. This can be especially damaging when agencies cluster, creating large single-use neighborhoods. By spreading offices throughout the region, federal projects can invigorate many different neighborhoods instead of negatively affecting just a handful.
Federal buildings farther from transit often use shuttle buses. These could also provide a desirable transit option for neighborhood residents, but security rules often bar them from riding. This has been part of the conversation around the Department of Homeland Security's new offices at the former St. Elizabeth's hospital site between Anacostia and Congress Heights.
Individual buildings can do a lot to help or hurt their neighborhood. The parking garage for the Patent and Trademark Office (PTO) in Alexandria is lined with townhouses on two sides, but other sides are just screened and set back from the street with landscaping, creating a dead streetscape. Many projects fall into this same pattern, with a mix of successful and unsuccessful components.

Security drives many design decisions and harms communities
The General Services Administration (GSA) is working to reverse damage to the streetscape from its massive headquarters in Foggy Bottom. The building is currently entirely disconnected from the street, but GSA plans to bring retail back to the building's street frontage.
To do this, they had to get creative with a factor that hampers the design of many federal projects, security. Security drives a lot of design decisions for federal projects.
In urban conditions, security hurts the streetscape by restricting building access from the street and forbidding retail from lining the outside of buildings. In more suburban conditions it creates large campuses, cut off from what little grid there is and keeping workers from being able to activate the area around them. These large campuses also restrict the ability for planners to attempt to reconnect neighborhoods.
By adapting, many agencies are tackling these issues. The GSA's headquarters was formerly a Level 5 security building. In its renovation, they created a graduated security system, where not all areas of the buildings require the maximum security. As a result, almost all the security bollards around the building could be removed, a marked improvement to pedestrian conditions.
The lower level of security makes street level retail a possibility, and the GSA is looking into opening the building's cafeteria to the public, allowing the agency to share this amenity with their neighborhood.
Sustainability goes beyond LEED
Federal buildings built today have more environmentally-friendly design features. This demonstrates leadership and forward thinking from GSA and the agencies, but Rollin Stanley, Director of Planning for Montgomery County, was careful to remind the audience that the greenest building is the one that already exists, and urged federal designers not get too caught up in LEED.
A LEED Platinum building with no transit options but hundreds of free parking spaces will do more harm to the environment that a building built to lower environmental standards. There are many different factors to take into account to judge a building's true impact on the environment.
Many federal buildings, like many private buildings, are building more parking spots than they need to. Federal agencies are often surprised by how many workers will choose to commute in ways besides driving. At the Mark Center in Alexandria, offices for the Department of Defense were expected to produce massive gridlock. Instead, 50% of workers utilize transit to get to the site.
Little touches can do a lot
Small-scale gestures have very positive effects on the areas around government offices. The PTO provides Wi-Fi in a small park adjacent to the offices and installed glass columns that light at night. Despite larger urban design failings, small gestures like these can make a big difference in neighborhoods.
Federal projects have their own strengths and weaknesses, but each gains from the collective knowledge of the projects that have come before. Agencies are generally moving towards better designed buildings, closer to transit, that give workers more flexibility. We will surely witness missteps along the way, but the trajectory for these buildings and the positive change they can bring to the areas is promising.
At last night's NCPC panel, "Redefining Security a Decade After 9/11," we were reminded that on security, Americans are a "cantankerous bunch." According to Brian Jenkins of RAND Corporation, US residents demand to feel 100% safe at all times at no cost to their way of life.
Jenkins, joined by architect Thomas Vonier and landscape architect Alan Ward, addressed this dilemma and others in a discussion on balancing physical security needs with good urban design. When it came to how much security is appropriate, though, the panelists diverged in their recommendations.
Vonier's talk seemed to encourage a "whatever it takes" mentality on introducing both visible and concealed security measures into the urban space. He embraced the use of "choke points," or highly supervised, securitized points that all people entering a site must pass through. Vonier lauded Lafayette Square as a successful example of an urban control zone.
In contrast to Vonier stood Ward, who turned to the Washington Monument as an ideal example of a minimalist solution to security concerns. The Monument received a security facelift in 2003 with the addition of sunken walls that naturally curve around the base of the hill on which the Monument stands, providing additional security without encroaching upon visitors' privacy.
Unlike Vonier, Ward seemed more inclined to respect historical precedents and maintain the natural order of a space to the greatest extent possible. He lamented the 18-foot descent that pedestrians endure when approaching the Capitol Visitor Center, a sensation he described as the antithesis to the entry experience one expects of such a grand building.
Jenkins and Vonier both suggested civic authorities reduce security risks from vehicles by creating pedestrian roadways with reduced or no car and truck access. London developed the "Ring of Steel" after a series of IRA attacks. This is a perimeter of Closed-captioned Television (CCTV), police, and bollards within the City of London, Greater London's financial district. According to Jenkins, as a result of the "Ring of Steel," the streets have been "pedestrianized," and commerce is thriving.
Ward, however, disagreed with adopting a similar approach. "We don't have the density of pedestrians" to eliminate cars from certain roads, he said. Ward also suggested that the economy would not support such changes in traffic patterns, which could "kill businesses."
The panelists bandied about a number of solutions to the question of how to simultaneously provide both security and amenity. Vonier referred to the classic necessity of more eyes on the street to increase vigilance against threats. He suggested that police and civic authorities encourage proprietors to take ownership of the sidewalks and streets in front of their businesses, creating a "defensible space."
During the question and answer session, Jenkins suggested that in order to make the public more accountable for security, governments must improve education and communication, helping individuals to better understand policy decisions and security protocol while empowering them to be more vigilant.
Disappointingly, some of the pricklier subjects, such as congestion pricing, closed circuit surveillance, and defense against airborne security threats were mentioned in brief but not explored much further.
Many questions still remained unanswered. How can design engage the public in the provision of their own security? At what point did Americans become passive potential victims, as many of the latest security measures suggest? Which works better: the prototypical Parisian cafe-style of surveillance, or the large setbacks and empty spaces prevalent in front of federal buildings?
Nobody seemed fully equipped to provide answers, largely because the issue frequently turns into a matter of subjective opinion, as the talks showed. At the very least, however, the panelists could all agree that many existing security features around DC, like the Jersey barriers outside of the Federal Aviation Administration's building, can and should be improved to reflect stronger urban design and a better connection to the pedestrian experience.
