Veterans Day closures: No "commutemageddon," and even some perks for those not working

Though roads closed and the Blue Line stopped running on Veterans Day, crowding and waits for commuters weren't as bad as some had feared. For people who had the day off, the closures even created an impromptu "open streets" event on car-free avenues. But many details, particularly for pedestrians and cyclists, came as a surprise.

The Concert for Valor did attract large crowds to the National Mall, but they were nowhere near the 800,000 people that concert organizers initially predicted. Immediately beforehand, they lowered the estimate to closer to 250,000.

"Our initial indications are everything went very smoothly," said National Park Service (NPS) spokesperson Mike Litterst. NPS was responsible for managing and coordinating road closures and security for the concert with other agencies.

Streets closed at 6 am for a 7 pm event

Thirteen hours before the concert began, all of the streets closed around the mall, including long stretches of Constitution and Independence Avenues and everything from 3rd to 17th Streets as far north as Pennsylvania Avenue and as far south as Maine Avenue. Commenters on our pre-Veterans Day post about the changes asked why the closures could not have begun after the morning rush.

"In general… closure time for the streets is a decision jointly made by all of the participating public safety and law enforcement agencies for safety and security reasons," said Litterst. "It allows the secure area to be properly and diligently swept and secured prior to the concertgoers entering. It is a security plan and process that has been refined over numerous large-scale events in and around the Mall over the years, including Independence Day, inaugurations, and large-scale races, such as the Marine Corps Marathon."

Cyclists, walkers, and joggers, however, enjoyed the car-free spaces. Throughout the day, photos and videos of people enjoying a nearly empty Constitution Avenue emerged.

"That was pretty fun. Let's close down Constitution more often," said Rob Pitingolo, who shot a video of the car-free boulevard.

But actually crossing the Mall was more difficult. Anyone entering the area between Jefferson and Madison Drives, 17th Street, and the Capitol had to pass through security checks, and those only opened at 10 am.

Metro served 40% more riders than last Veterans Day

Metrorail trains carried about 523,000 passengers on Veterans Day, says spokesperson Dan Stessel. Last year, when there was no large event, roughly 375,000 people rode Metro.

Personally, I noticed slightly more people than usual on my morning and evening commutes on Metro from Shaw to Braddock Road. Despite fewer trains and no Blue Line, my experience was better than on previous "minor" holidays when scheduled track work and crowded transfer stations made the inconveniences of reduced schedules even worse.

"From our perspective, the day went really well," said Stessel. "Service levels were appropriate to meet ridership demand at all hours of the day, and we believe we struck an appropriate balance between the needs of regular commuters with those heading to the Concert for Valor."

Greater Greater Washington readers asked why Metro didn't keep the Blue Line open until later in the day. Metro also banned bikes all day.

"No doubt, the service changes were in place to handle crowds that, in the end, were not as large as the Park Service permit," said Stessel. "We make no apologies for this. We have to plan for the worst and hope for the best."

What could be better next time?

Some of the details of the street closures and service changes got lost in the media blitz before the event. For example, NPS and the press could have more clearly communicated that Constitution and Independence Avenues would be free of cars and open to pedestrians and cyclists. Most news reports focused on the effect on drivers.

Also, NPS could work to minimize the impact on cyclists. While drivers could still use the 3rd Street (I-395) and 9th Street tunnels to cross the Mall, cyclists couldn't. They had to cross either east of 3rd or west of 17th. NPS could designate corridors, perhaps along one of the streets at the edge of the security cordon, for riders to cross the Mall. Many, myself included, would have taken advantage of these.

Street trees can't ask for more soil themselves, but new DC standards will help them get it

Trees are a special quality of DC's urban environment, but the city's tree canopy has been shrinking in recent years. A new set of design standards ensures new construction on the roads and in public space includes enough soil so that trees can thrive.

In April 2014, the District Department of Transportation released new green infrastructure design standards for its projects. A major goal is to capture rain directly where it falls rather than dumping it into sewers or rivers, which causes flooding, spreads pollution, taxes sewer systems, and wastes an increasingly valuable resource.

The standards push for green areas to retain stormwater in heavily-paved areas like sidewalks, plazas, and streets. With them, DC joined a growing group of cities like New York, Philadelphia, and Chicago that use "low-impact design" features to help restore ecological function to urban areas.

But the District is distinguishing itself by also requiring a minimum soil volume for street trees, which must now get 600 to 1,500 cubic feet of soil (depending on how large they can grow).

Trees play an important role in our lives

Many of us have fond memories linked to trees. Perhaps you had a favorite climbing spot as a kid or you planted one in the yard of the first house you bought. Maybe you regularly cool off in a tree's shade during a heat wave or have called the parks department when one was vandalized in your neighborhood.

People instinctively want to be around trees, which makes sense when you consider how good they are for human health. Trees make cities cleaner, more inviting, safer, and more profitable.

According to Casey Trees, a local nonprofit, DC's tree canopy currently covers 35 percent of its land, down from 50 percent in 1950. Advocates want to to turn that around and reach 40 percent by 2035. An increase of five percent may sound small, but to meet this goal the District will need to add more than 2,000 acres of tree canopyan estimated 216,000 trees.

It's not just about the number of trees. While trees are part of almost every DC street, mature urban trees are rare, meaning the city frequently loses out on the value and utility they bring to public spaces.

Mature trees are significantly more valuable than young ones to the ecosystem. A tree with a 30-inch trunk circumference delivers 70 times the air quality benefits of a tree with a 3-inch trunk. And mature trees "intercept," or prevent from hitting the ground, far more rainwater per year than young ones. That reduces the amount of stormwater that flows into sewers and rivers, which frequently causes flooding and carries pollutants. One model found a 40-year-old hackberry tree intercepted 5,387 gallons of rainfall per year while a 5-year-old one intercepted only 133 gallonsa 40-fold difference.

Soil is key to healthy trees

The long-term success of a tree is fundamentally linked to the quantity and quality of the soil it grows in. To make a real impact the District needs to not just plant trees, but give them the space and nutrients they need to grow to maturity. , soil retains rainwater directly where it falls, which is good because diverted rainwater leads to flooding, spreads pollution, taxes sewer systems, and wastes an increasingly valuable resource.

For context, the average street tree in a typical 4' x 4' space can have as little as 75 cubic feet of soil. This is less than one tenth of what experts recommend for long-term tree health. The new policy will guarantee space for roots, and coupled with proper care and maintenence, will enable trees to grow and thrive for decades to come.

There are an increasing number of ways to put soil below streets, parking lots, and plazas to give trees soil even in dense or pedestrian-heavy areas. For example, the new American Veterans Disabled for Life Memorial at Washington Avenue and 2nd and C streets SW, which my company worked on, suspends the pavement with soil cells, modular, stacking units that leave space for soil and roots for 30 trees.

DC's renewed commitment to trees will pay off in the long term

These new green infrastructure standards arise from years of discussion, public comment, and pilot projects. "DDOT has attempted to change the culture of urban stormwater management by applying these standards to all capital improvement and private sector projects in the public space," said (former) DDOT Chief Engineer Ronaldo Nicholson in a press release in April about the new standards.

Residents might not notice all that much change immediately. After all, trees take years to grow and reach their potential. But our children will.

Let's build a great bike lane for Route 1 in College Park

People who bicycle in College Park were very excited last year when Governor Martin O'Malley announced funding for bicycle and pedestrian improvements on Route 1 in College Park. But the state's new plan for the road just includes basic, painted bicycle lanes. The road needs better bicycle infrastructure to be safe and attractive for cycling.

When the funding was announced last summer, one news report said that the plan called for a "bicycle and pedestrian trail along US 1 from College Avenue to MD-193."

Northern Prince George's county has an excellent bike trail system paralleling Route 1 and Metro's Green Line, but many of the larger roads in the area are hostile to cyclists and pedestrians. Route 1 does not even have continuous sidewalks in many stretches between the University of Maryland and the beltway, and there are no protected bike lanes or cycletracks on any of the larger numbered state roads in the area.

The state's design disappoints

Last week, the Maryland State Highway Administration (SHA) described a plan for section of Route 1 between College Ave. and Greenbelt Road that would create a narrow five-foot painted bike lane (four feet plus a one foot gutter pan) next to the curb.

A diagram from an SHA newsletter describing the proposed Route 1 cross-section.

Given the bus and delivery truck traffic on Route 1, a narrow bike lane could be hazardous, squeezing cyclists between an 8-inch concrete curb and large vehicles in dense traffic. In addition, buses that are stopped or idling by the curb would force cyclists into the roadway and mixed trafficsomething neither cyclists nor drivers prefer.

The SHA design is unlikely to be popular with either cyclists or drivers. College Park officials asked SHA hard questions about whether the design could include protected bike lanes, but SHA representatives didn't have good answers beyond, essentially, "this is where we usually put bike lanes."

This design decision will make an enormous difference in the long run for College Park's accessibility and business development. Since SHA will be rebuilding the entire roadway, this is once-in-a-generation opportunity for Prince George's County.

Will the bike lanes be part of an urban street design that is welcoming to pedestrians, bikes, and bus riders? Or will they lanes just be a stripe of paint between the curb and a roadway that is designed more like a suburban strip or rural highway?

Why not a cycletrack?

Fortunately, there are much better designs that cities nationwide have used for decades. Some even would allow for a narrower road, meaning Maryland would have to buy less land and do less of the expensive full-depth road reconstruction.

Protected bike lanes, or cycletracks, physically separate between cyclists and vehicle traffic, offering a more comfortable and safer ride.

Twenty-four states use these lanes, which many cycle advocates call protected bike lanes and others call cycletracks. The District uses cycletracks extensively, and they have coincided with a boom in population and tax revenues for the city.

A Route 1 with such a lane, keeping the same proposed center median, could look something like this:

Drawing by the author.

Cyclists do not have to compete with faster vehicles that can hit or kill them, nor do they have to compete with slower pedestrians on crowded sidewalks (like they do now). This is a win-win for all road users and dramatically improves everyone's safe travel.

A two-way cycletrack might also be an option, especially on the west (University) side of Route 1.

Alternatively, SHA can also follow the lead of many other states by putting in buffered bike lanes. These separate the bike lanes from vehicle traffic within the road using striped or curbed buffers. While not as good as cycletracks or protected lanes, they are far superior to the simple painted lanes in SHA's design.

Although there has limited space in the right-of-way on Route 1, SHA is working on expanding the right-of-way beyond its existing width. This gives College Park a rare opportunity to create enough space to safely accommodate cyclists and pedestrians.

Protected bike lanes will encourage bike commuting to the university and surrounding businesses and will take car traffic off the road. In order to entice people to bicycle, people need to feel safe. Basic painted bike lanes alone will not achieve that.

National Airport will get better, while Dulles will stay decrepit, for now. But there's hope.

Reagan National Airport will get a new concourse and larger screening areas, airport officials announced today. Meanwhile, Dulles International Airport's decrepit United Airlines concourse isn't getting replaced anytime soon. However, there's hope for Dulles to get out of its doldrums.

For a while, the Metropolitan Washington Airports Authority has been facing a dilemma. More passengers are using National, while domestic traffic fell at Dulles. Dulles is not just unpopular, but also expensive for the airlines.

Where most people prefer each airport. Image from MWCOG.

A 2013 Council of Governments survey found that National became the preferred airport for flyers in even larger swaths of Prince George's and Northern Virginia than it was in 2011. It's growing, and has been feeling the pinch in crowded waiting areas, parking, and security screening lines.

Changes should fix crowding problems at National

According to a briefing this morning, MWAA will build a new concourse for the regional jet flights. Today, flyers have to take a shuttle bus to these flights, which adds a lot of time and hassle, and the waiting area is crowded. There's a building to the north of the existing concourses that's now MWAA offices; that are will become the new concourse.

The security screening at terminal B/C, which now crams into the three hallways accessing the piers with the gates, will move upstairs to the level with the ticket counters.

Concept plan for the new concourse. Image from MWAA via FlightGlobal.

The airport hit a record 20.4 million passengers in 2013, and MWAA expects it will soon pass 22 million. National is one of the few airports in the nation with legal limits on its airplane traffic. There is a set number of "slots" which let airlines take off or land planes, and a perimeter rule restricts flights to airports more than 1,250 miles away, except for a set of exemptions that Congress has added over the years.

Congress added eight new daily long-distance exemptions in 2012. Four of those, which went to airlines without a lot of flights at the airport already, also added to the number of total slots. When US Airways and American merged, the Department of Justice further required them to give up slots which went to Southwest, JetBlue, and Virgin America; those airlines are flying larger planes than US Airways had been.

But National has very limited space for new growth. Meanwhile, Dulles domestic flying is caught in something of a spiral: it's less desirable than National, but its facilities also need more work. If people don't fly there, the airport will take in less money, and airlines end up paying more per passenger. That might convince airlines to fly there less, meaning fewer people fly. And so on.

Isn't that just as well?

MWAA frets a lot about this, but urbanists might ask, why is that a problem? National is more convenient for more people and has better transportation access. Why not have more air travel happen near the center of the region?

However, National's runways can't accommodate many more flights than there are today. The airlines could fly more larger planes (like 737s instead of regional jets; there isn't room for widebodies), but there's a limit on bigger gates. And even with the planned changes, there's not a lot of spare space for passengers in the terminals.

Many flights and people are going to have to go to Dulles and BWI, and that means we all should want those airports to have a lot of flights. Dulles has long been a United hub. Most large airlines today fly a "hub-and-spoke" network where they fly almost entirely to and from their hubs. Without a United hub, there wouldn't be flights to a lot of smaller eastern cities from Dulles, since United depends on connecting passengers to fill them.

This summer, some airline analysts even said United should drop the hub. Part of the reason: since it merged with Continental in 2010, United has an even better-performing (though also constrained) hub in Newark.

United hasn't taken that advice, at least not yet, and a lot of people said it's bad advice. But it reminds us that United does have to be successful at Dulles. And if people don't want to fly in and out of Dulles, that creates a problem.

Dulles is more expensive

There is another reason people don't like to use Dulles, and in particular, United's gates there: Their concourse is awful. The C and D gates are in what was originally built to be a "temporary" concourse. It's old, dark, and depressing. The A and B concourse, which serves international flights and other airlines, looks great... except for the little end of A for United regional jets, which is also terrible.

When MWAA built Dulles' new train, it didn't put the station right under the existing concourse, but a short ways away where the permanent one is supposed to go one day. Until that happens, however, you not only have to go from check-in to security to a train to the gate, but have an extra long walk.

United CEO Jeff Smisek has said United is reluctant to expand at Dulles because it is more expensive than other airports. Airports have to be self-sufficient and pay for their facilities and operations through revenue they earn inside the airport (like restaurant concessions) and fees airlines pay. When an airport wants to build new facilities, it has to take on debt that raises the costs for the airlines.

Airlines usually look at this as "cost per emplaned passenger," or CPE. If passengers go up, the overall payment from airlines doesn't change, but the denominator rises, so the CPE is lower. According to MWAA spokesperson Chris Paladino, Dulles' is now about $26, though international carriers pay more and domestic ones (like United) less. The CPE at DCA is around $12 and at BWI under $10.

So not only is Dulles less desirable for passengers, but it's pricier for airlines. If MWAA built a new concourse for United, it would expect United to foot most of the bill, and that means United would see Dulles as even more expensive than it is.

While Smisek isn't revealing all of United's calculations about what a new concourse might be worth to them, it's not unreasonable for him to worry about that cost on top of all of Dulles' other costs. That means either Dulles stays crummy or it gets even more expensive.

MWAA needs more revenue at Dulles

To lower the CPE, MWAA is trying to create new revenue at Dulles. Paladino, the MWAA spokesperson, said the authority is trying hard to do that, such as bringing in higher-end shopping and better restaurants to Dulles (and National).

MWAA has also been looking at developing some of the land around the airport with hotels and other uses, and pushing ideas for increasing cargo capacity at Dulles.

Unfortunately, this pressure to get more revenue at Dulles leads MWAA to push policies that are destructive for the region as a whole. It and other airport boosters lobby for more north-south highways along the Outer Beltway route so people can drive to Dulles, even though flyers would be a tiny fraction of the traffic on the road. It would mostly fill up with people buying houses in new sprawling subdivisions at the region's fringe which would suddenly become more valuable with a highway.

New agreement will subsidize Dulles with revenue from National

The changes MWAA announced today are part of a proposed agreement with the airlines. If they ratify it, in addition to the changes at National, $300 million of revenue from National will help reduce the debt load at Dulles. Aviation reporter and GGW contributor Ned Russell reports that National's CPE will rise to $14.68 and Dulles' fall to $25.48. That's still a big gap, but a little less than without the shift.

This seems sensible. While it's a good thing more people are using National, it's also not fair for the more desirable airport to have lower costs. The airlines want to fly at National no matter what; higher costs won't deter them. At the very least, MWAA shouldn't be making Dulles less desirable.

The new agreement doesn't include any new concourses at Dulles, Russell said, but if United's CPE can be more equal between the two airports, in a few years it could make economic sense for MWAA and United to agree to invest in that airport.

Mini-circles calm traffic in AU Park but stir opposition

For a year now, drivers and cyclists on 42nd Street NW encountered a traffic calming device that's new to DC: Small traffic circles made out of plastic pylons. Permanent versions will soon replace them. But not all neighbors are pleased.

42nd Street is a popular route through American University Park. It offers a way to reach homes, schools, and a senior center without using busy Wisconsin Avenue. But drivers speed through the area and it was not safe enough for pedestrians, a 2011 study of the area found.

The solution? Mini-circles, a traffic calming device that's common in places such as Seattle, Portland, and Palo Alto, California. These provide a more pleasurable way to slow traffic than a speed bump. They are more effective than stop signs, since drivers may ignore a sign but must slow down to navigate the circle.

On 42nd Street, DDOT installed two mini-roundabouts a year ago to slow cars but keep the road working as a through route. Warren Street splits a block to the west and meets 42nd in two separate curved intersections where drivers take the turns too fast and often blindly.

American University agreed to pay for the traffic calming as part of negotiations over its most recent campus plan. That will fund more permanent versions, whose construction is scheduled to start on November 19.

Some neighbors say no

When the circles first appeared, some drivers complained of being confused. Sherry Cohen, a resident, said she thought the circles were dangerous.

The data, at least in Seattle, says otherwise: A 1997 study found that crashes dropped 94 percent in areas that got mini-circles. The city found that, "In addition to reducing [crashes], traffic circles have been effective at reducing vehicle speeds but have not significantly reduced traffic volumes."

Recently, Joan Silver, who lives right at the corner of 42nd and Warren, started circulating a petition opposing the permanent circles. She wants a new study to consider instead using stop signs or speed bumps.

Silver complains that the circles "do not satisfactorily or adequately address the range of traffic-related safety issues at the specified location, and ... have generated a number of dangerous conditions in their own right and negative impacts on properties immediately surrounding them."

Matthew Frumin, who chairs the area's Advisory Neighborhood Commission (3E), canvassed the neighborhood after receiving the complaints. In an email to the other commissioners and some of the petitioners, Frumin said that neighbors around the northern circle strongly favored making it permanent.

"While they do not think the circles are the only possible solution, they believe even the temporary northern circle has improved traffic conditions considerably," he wrote, "and that in the next phase when the circle takes its new shape and the crosswalk is added, conditions will improve further. If there is not a unanimous consensus around that, there is a very strong and decisive one in favor of the circle." Residents around the southern circle had more mixed views.

Comments on the petition say that the circles confuse some drivers (who even may go around the wrong way) or cause backups. Others complain that the pylons are ugly.

The permanent circles should address the aesthetic complaints. They will have landscaping that will create an attractive focal point for the residential neighborhood.

And fewer drivers will be "confused" as they get used to the circles. In other cities, drivers have not found them confusing or have adjusted. Perhaps a sign could help; some circles have them, though signs are also less attractive.

Trying new designs that have worked elsewhere should be the norm for our neighborhood streets. Hopefully DDOT will continue to experiment with ways to slow traffic down and make streets safer and more pleasant for everyone.

It'll be a rough commute this Veterans Day for people who still have to work

While government workers have the day off for Veterans Day, many people don't. They will face challenges traveling around the region: Metro will temporary suspend service on the Blue Line, and road closures for the Concert for Valor will block driving and bicycling routes along and across the National Mall.

Image from WMATA.

The Concert for Valor, which begins at 7 pm, is expected to draw up to 800,000 people. Corporate sponsors are funding additional Metro trains to handle the crowds for the concert.

Metro plans to operate weekday peak frequencies with more eight-car trains than it normally offers immediately before and after the concert. However, Metro will suspend the Blue Line and replace it with some Yellow Line trains running to Franconia-Springfield. A bus bridge will connect Pentagon and Rosslyn, and a special shuttle service will serve Arlington Cemetery.

The National Park Service, which is managing access to the Mall for the concert, will close Constitution and Independence Avenues and all of the cross streets from 17th Street to 4th Street (except the 9th Street tunnel) starting at 6 am.

"Minor holidays" mean crowded trains

Metro has faced criticism for crowded trains on so-called "minor" holidays during previous years. Metro ridership declines on these holidays, which include Columbus Day, Presidents' Day, and Veterans Day when government offices are closed but many private sector employees remain open, its own data shows. Metro frequently reduced service on these days and scheduled track work. However, that meant long waits and crowded trains and platforms.

The morning commute this Veterans Day will likely look a lot like ones past. All terminal stations will see a train only every 12 minutes, with the Yellow Line replacing the Blue Line at Franconia-Springfield. There is no scheduled track work that could disrupt this schedule.

The evening commute will benefit from the additional trains that are planned for the concert but commuters will have to share trains with the crowds bound for the Mall.

Cyclists have to take long detours

Cyclists will face the biggest issues commuting across the Mall tomorrow. There will be no opportunities to cross the Mall between 3rd Street and 23rd Street. Jefferson and Madison Drives along the Mall, both popular east-west bike routes, will also be closed.

Unlike drivers, cyclists do not have the option of taking the Third Street Tunnel (I-395) or the Southwest Freeway to bypass the closures. People can get to offices located south of Independence Avenue by taking Maine Avenue SW to either 3rd Street or 7th Street SW. However, neither is ideal as there is no contiguous east-west route through the L'Enfant Plaza and Federal Center SW neighborhoods from either street.

Crossing the 14th Street Bridge and getting to or from Virginia from downtown DC will be tough. The bridge approach from East Basin Drive and Ohio Drive SW will be open but access will only be available from 23rd Street or via a roundabout journey through Southwest that includes looping south to Maine Ave SW and returning north. Another option is to bypass the 14th Street bridge entirely and use either the Memorial Bridge or Theodore Roosevelt Bridge.

All of the options for cyclists headed to places like Alexandria and Crystal City from the District are likely to add significant mileage to their journeys, especially those coming from points further north or east of the Mall.

Cyclists are already feeling the impact. 4th Street between Jefferson and Madison had been closed since at least the evening of Tuesday, November 4. Jefferson closed today between 3rd and 4th without any advance notice. This has affected my daily commute along the Mall to the 14th Street Bridge; I could not find any notification of these closures after a Google search.

Will tomorrow bring chaos?

A lot of people will still need to get to work on Veterans Day, but the Metro frequencies, road network, and other transportation infrastructure seem to be set up with the assumption that the only people traveling are going to the concert.

Agencies could do better to plan major events on the Mall on a minor holiday. Metro should ensure that there is frequent enough rail service to keep trains uncrowded and waits reasonable, while NPS should consider the rapidly growing number of bike commuters and provide workable alternative bike routes.

For one weekend, Georgetown got wider sidewalks

Georgetown widened the sidewalks along M Street for a weekend in mid-October. Temporarily borrowing 47 parking spaces from the street created a comfortable walking experience for thousands of people.

American, Georgetown, and George Washington universities all held their annual parent and family weekends October 17th-19th. Since these events cause foot traffic to spike along M Street, my organization, the Georgetown Business Improvement District (BID), placed barricades that turned street space into pedestrian walkways on M from Wisconsin Avenue to Potomac Street.

The average sidewalk on M Street in Georgetown is only eight feet wide, much narrower than most around the city. Given that we've recorded nearly 4,000 people using the M Street sidewalks during any given hour on busy weekends, that's a problem.

In 2013, the Georgetown BID started Georgetown 2028, a community planning process to look at changes the neighborhood will need over the next 15 years if it is to continue to thrive and to enhance what is great about this community. The pedestrian experience is an important theme of the plan.

This isn't the first time Georgetown's sidewalks were temporarily widened: a sidewalk on Wisconsin Avenue added space in both 2013 and 2014 for the Georgetown French Market. That project, though, merely made room for sidewalk vending. October was the first time a sidewalk grew just to add space for pedestrians.

How the sidewalk widening worked

A lot went into making sure both pedestrian and car traffic ran smoothly throughout the weekend. We used steel barricades and some water-filled barriers to block off roadway space.

The change maintained all moving lanes of traffic and the existing bus stop. Where there wasn't an existing curb ramp, we installed temporary aluminum curb ramps to ensure that the space was accessible for people with disabilities or stroller users. We created specialized loading plans for the businesses along M Street that load through their front doors, including four restaurants that need daily food delivery and trash pickup.

We didn't want to encourage drivers to simply circle the neighborhood looking for a free street space. To lessen the impact of removing 47 parking spaces during one of the area's busiest weekends, we arranged discount parking rates at nearby garages and posted signs telling drivers about them. We also made the northbound Circulator free so that people could park in garages on K Street and ride up the sometimes steep hill to the retail stores on M.

How well did it work?

After the weekend, we compared how many people walked along M Street to the average over four weekends. The data comes from automated counters which don't cover the expanded pedestrian area. Even still, the total pedestrian traffic rose by 9.8%, yet the overall sidewalk congestion on M Street was lower than usual.

As for parking, the 47 spaces that disappeared for the sidewalk widening were replaced three-fold by available spaces in the garages. The garage at 3307 M Street reported 56% more cars than average entering their lot on Saturday the 18th.

We think those numbers, coupled with the feedback we've received, makes it fair to call the M Street sidewalk widening a success.

"I walked through the sidewalk closure area along M today on the north side," wrote Eileen McCarthy, a DC Pedestrian Advisory Council member. "It certainly does help to relieve sidewalk congestion."

"I believe any effort to make M street more pedestrian friendly will provide for a more enjoyable experience for tourists and shoppers," added Thomas, a Georgetown visitor. "That was certainly my experience this past weekend. I can recall in recent visits to Georgetown that it was a challenge to navigate the sidewalks without being overly crowded by others. I am happy with the expanded sidewalk, and hope this measure becomes a permanent feature."

Finally, Jamie Scott, Georgetown University's assistant director of community engagement, wrote us to say, "the parking deals during Parents Weekend were very popular. ... Our garage attendants had the information, and when the garages filled up on Friday, they directed guests to the garages in Georgetown."

Let's do it again!

The BID is currently evaluating all facets of the experience, but early feedback from residents and businesses is to do more of these types of widenings on weekends when conditions warrant. We will be meeting with our community partners to get their views and ensure we get these projects right on all the details.

For example, we learned that we need to make it easier for people to load things like small furniture pieces into a car or taxi. A 36-inch high fence makes that very challenging.

We at the Georgetown BID appreciate the District Department of Transportation (DDOT)'s willingness to work with us to try a new way of managing our sidewalks. Support for this type of project is critical if we're going to develop better ways to use our limited public space. It's an experiment we're glad we got to try.
