Station cleaning – the end product

Today’s snow storm means Metro’s been limited to their underground service map only.  Given that buses are out of commission, this low level of service is the only real way to get around town.  It also means there’s plenty of time to spend in the stations waiting for trains.

So, while waiting at Potomac Avenue, I couldn’t help but snap a few pictures of the newly cleaned and whitewashed vaults, all part of Metro’s earlier noted station enhancement program.  For Potomac Ave in particular, the mid-way photos already showed a huge improvement over the dirty and grimy concrete vaults.  Given that Potomac Ave was one of the stations Metro painted years ago to improve light levels, the last step was to essentially whitewash the station vaults to complete the cleaning process, and then light those vaults up by replacing all the burnt-out light bulbs.

The difference is stark.  Today:

Let there be light

Following up on recent discussion of Metro’s lighting, it’s important to understand how much the surface that’s to be illuminated matters in Metro’s indirect lighting scheme.  Earlier, I noted that Metro is currently going though a process of deep-cleaning several stations in the system – replacing light bulbs, cleaning the walls, etc.   The Washington Post had a great article in March on the process for each station:

Blasts of steam from the hoses they carry scour dust from train brakes and concrete away from the panels. Sensitive equipment, including pylons on the platform, is protected from the spray, but the station is warm and misty.

Once the station is cleaned, the crew will re-bronze rails, paint kiosks and repair tile, among other tasks.

A station gets enhanced about every three and a half years. The crews do two dozen stations a year, focusing on indoor stations during cold weather.

“We’ve got it down to a science,” says Tom Morrison, Metro’s superintendent of contract maintenance and station enhancement. The job begins with a lot of prep work after the Red Line shuts down at midnight. Power to the third rail must be cut and station equipment protected.

The crew must wrap up about 4 a.m. The workers will need to be gone, the equipment stored at the end of the platform or hauled away and the station dry by the time passengers arrive and trains start running at 5 a.m.

It’s not easy adjusting to the schedule — five overnights in a station and two off days trying to have a real life — but workers at least get a direct view of what they’ve accomplished. “We can see the before and after,” says craft supervisor Andre Jordan.

Steam cleaning the walls makes a huge difference.  This process is currently underway at my nearest station, Potomac Avenue.  Dr. Gridlock noted earlier in the year each of the stations scheduled for a “station enhancement,” as Metro describes the process:

Major Enhancements: Dunn Loring, East Falls Church, Eisenhower Avenue, Forest Glen, Medical Center, Potomac Avenue, Twinbrook, Wheaton, White Flint, U Street, Vienna, West Falls Church.

Mini Enhancements: Ballston, Bethesda, Brookland, Court House, Foggy Bottom, Franconia-Springfield, Friendship Heights, Rockville, Shady Grove, Smithsonian, Virginia Square, Woodley Park.

The majors and the minis involve different types of work. A major takes about three months. A mini takes about 25 percent less time. I watched some of the overnight work for a “major” at Cleveland Park. During the hours the station was closed, crews on lifts power washed the station’s concrete ceiling and walls. I could see the before and after, and the difference was remarkable as they removed the tunnel dust that gathers in the station.

To get an idea of how much dirt and grime accumulates over the years, have a look at the process in action:

Metro initially ‘painted’ several stations in order to lighten them up a bit – but the painted surfaces don’t quite have the same warm feeling that the original concrete does.  They also show the dirt and grime more than their concrete counterparts.

Compare, side by side, the clean side of the station to the uncleaned one:

It’s not just the grime accumulating on the lower portions of the vault – there’s a huge difference in the dirt on the bottom edges of the coffers – that’s not just shadow (despite my crappy camera).

A New Square for Potomac Ave – Part II

Following up on the vision for the public space at the Potomac Ave Metro station, I wanted to offer a glimpse at what the square might look like in the future.  All of the great squares, circles, and other urban spaces are not just defined by their public spaces, but also by the buildings that frame the space.  With the addition of Jenkins Row to this intersection, Potomac Ave is approaching both a complete streetwall around the square, as well as the critical mass of various neighborhood services.

With that in mind, I turn to the draft of the Pennsylvania Avenue SE Land Development Plan.  Of specific interest for this intersection is the Potomac Ave sub-area plan.  This iteration identifies the 1401 Pennsylvania parcell as a key redevelopment opportunity.  A quick glance at the area will quickly identify the SE corner of the square as the weak link, containing a couple of vacant lots, a parking lot, and New York Pizza.  Living in the area, I love what NY Pizza brings to the ‘hood, so I would sure hope that any redevelopment helps them find a new home.  Even so, you can totally tell it used to be a Pizza Hut.

With Jenkins Row filling in the old gap on the eastern edge of the square, this parcel is the one missing link (aside from the Metro station plaza).  As such, the plan calls for new mixed-use construction at the side in the same mold as the Jenkins Row development – first floor retail with office and/or residential above.

A couple of points stand out.  First, when combined with the reconfiguration of the intersection’s traffic flow, buildings fronting on the new square ought to see more foot traffic – at a very least, the sidewalks they front on should be far more attractive to pedestrians walking either around the square or passing through it.

Second, the current Metro plaza, as mentioned above, would then be the one missing part of the streetwall enclosing this square.  Given that the station is such a focus for foot traffic, this is fine – but one potential benefit is that a taller structure on the 1401 site is directly in the line of sight of Metro patrons coming out of the station’s escalator well.

All together, such a project could be the keystone in the arch for this public space.  As of right now, I’m unaware of any specific plans for the site.  I’ll just enjoy my pizza until then.

But seriously, if this site does get developed soon, you gotta keep the pizza.

A New Square for Potomac Ave

July’s issue of the Hill Rag contains some interesting tidbits in their ANC 6B beat report about a potential reconfiguration of the traffic patterns at the intersection of Potomac and Pennsylvania Avenues in Southeast Capitol Hill.  Talks of reconfiguring Penn. Ave’s course through Capitol Hill seems to be in the news a lot these days, with Greater Greater Washington talking about the process going on just up the road around Eastern Market.

DDOT’s proposal for the intersection is to merge the three existing traffic islands in the current ‘square’ while re-routing Pennsylvania’s traffic flow around the perimeter of the square.  DDOT’s presentation showed two potential plans for remaking the intersection – one from the Middle Anacostia Crossings plan, and their preferred alternative.

Potomac Ave Preferred Alt

(Preferred Alternative)

The one key difference between the initial MAC plan from 2005 and the preferred alternative is the elimination of the east-west crosswalk through the square.  The initial plan called for pedestrians to be able to access the square while standing in the median of Pennsylvania Avenue.  This element was dropped from the preferred alternative.

The Hill Rag’s reporting made it seem that the ANC commissioners did not take kindly to the options presented:

While the commissioners and audience members didn’t seem to particularly enjoy the current layout, DDOT’s plan was universally panned for a number of reasons. One woman who lives near the intersection said the plan doesn’t go far enough to increase pedestrian safety, and she urged DDOT to consider installing a traffic camera in the area to cut down on driving violations. Another woman said that creating a traffic circle would obstruct the view of the Capitol building for drivers heading west on Pennsylvania Avenue.

Commissioner Carol Green said that the plan was unreasonable because it would prevent pedestrians from directly crossing Pennsylvania Avenue at the intersection.

“There’s going to have to be some way for them to cross without going a block out of their way, because that’s essentially what you’re asking them to do right here,” she said. “I can tell you for sure, they’re not going to do it.”

Commissioners voiced frustration when it became clear that the DDOT proposal was the only plan on the table right now. If the upcoming public comment period reveals that the community mainly objects to the plan, the entire planning process would need to start over and the project would be delayed for several years.

I’m not sure any of these criticims have any merit. Taking them in order:

Traffic cameras. These kinds of programatic elements are kind of beside the point when discussing major design decisions.  By forcing Penn Ave traffic to make a turn, it will naturally slow things down.  Traffic law enforcement strategies are a separate issue.

Obstructed views for drivers. Give me a freaking break.  Drivers will have a completely unobstructed view of the Capitol Dome on the blocks preceeding and following this square on their way into town.  By reconfiguring the public space here, may pedestrians might get some of that view, too.

Prevention of directly crossing Pennsylvania. I have no idea what Carol Green is talking about here.  I live nearby and have crossed this intersection many times, and either of the proposed changes would make it far easier to get across Pennsylvania.   The new square will make it much easier to traverse up and down 14th street, as you now only have to cross two streets to do so, whereas before you have to cross four.  Furthermore, there’s more than enough evidence on the ground of  ‘choice paths’ worn into the Pennsylvania median strip from jaywalkers cutting directly across:

Looking at either plan, I can’t see any scenario in which a pedestrian crossing Pennsylvania will have to go a block out of their way.  Perhaps Comissioner Green was referring to people travelling along Pennsylvania rather than trying to cross it.  It’s true that these Pedestrians will now have to walk a short distance around the square, but in that instance they wouldn’t save any time by walking in the street – as they would simply be walking through traffic, rather than the current practice of jaywalking to get across.  Even so, a few rough calculations from the aerial maps show that a Pedestrian traveling on the southern side of Pennsylvania Ave would have to walk an extra 70 feet (~400 ft vs. ~330 ft) to cross from one side of the square to the other. When presented with reasonable alternatives, as we see from various other squares and circles in DC, pedestrians will take them.

All things considered, I fail to see what the commissioners are concerned about.  This concept takes the current arrangment of public space and prioritizes pedestrians over cars.  I’d prefer to see the iteration from the MAC plan, making this square a more accessible place with four crosswalks rather than two, but the general concept is solid.  Jaywalking at this intersection is rampant.  It’s both a safety hazard and an indicator of a poorly designed space.

On the other hand, the opportunity to vastly improve the safety of this intersection, as well as provide a new public space for the neighborhood is too great to simply dismiss.
