Four big questions for a Georgia Avenue streetcar

As plans crystallize for a north-south streetcar in DC, four big questions will drive what the line ultimately looks like:

  1. How will the line snake through the center of the city?
  2. Will it reach Silver Spring?
  3. Will there be dedicated lanes, and if so, where?
  4. Is there any money to actually build anything?
Planners from the District Department of Transportation (DDOT) are still months away from settling on final details for the North-South Corridor. But at a series of public meetings last week, these big questions came into focus.

How will the line snake through the center of the city?

DDOT's latest report focuses on four potential alternate routes, but project manager Jamie Henson says DDOT could still mix and match components of multiple alternates to create the final path.

Four route alternatives under study. Dedicated lanes could potentially fit on the purple and blue sections. Image from DDOT.

North of Petworth, DDOT has settled on a Georgia Avenue streetcar alignment going at least as far north as Butternut Street.

The line could run south from Petworth down Sherman Avenue as far as Florida Avenue, or it could stay on Georgia. Georgia is wide enough for dedicated lanes and is lined with shops instead of houses, so it would probably attract more riders, but Sherman would offer a more stark contrast to the route 70 Metrobus.

South of Florida Avenue things get really interesting.

The route could stay on 7th Street through downtown DC, but that duplicates Metrorail's Green Line, and 7th Street isn't wide enough for dedicated lanes. Or it could travel on 14th Street, where population density is most concentrated and where it's a long walk to any Metro stations. But 14th Street is already booming; a streetcar might help more elsewhere.

11th Street and 9th Street are intriguing possibilities. Infill and commercial development have lagged there relative to 14th Street. Would a streetcar bring a 14th Street-like boom? Meanwhile, both 11th and 9th are wide enough for dedicated lanes.

9th Street is already home to one of DC's only existing bus lanes. Though the bus lane is lightly used and poorly enforced, that might make 9th a particularly easy place to add streetcar lanes.

To traverse the National Mall, the line could either turn onto F Street through downtown and then use 7th Street to go south, or it could turn onto Pennsylvania Avenue and then use 4th Street.

The F Street to 7th Street option seems to be a path of less resistance, could fit dedicated lanes, would be more central to the National Mall, and would directly serve The Wharf development at the Southwest waterfront. On the other hand, 4th Street would better serve the existing Southwest neighborhood.

Will it reach Silver Spring?

Silver Spring is a natural end point for this corridor. It's big, dense, and already one of the DC region's largest multimodal transit transfer points.

Around 4,000 DC-bound passengers board WMATA's route 70 Metrobus in Silver Spring every day, with still more boarding the parallel S-series routes. There's tremendous opportunity for the streetcar to reach more people and have a greater impact by ending in Silver Spring instead of DC.

But for that to happen, Maryland and Montgomery County have to step up with plans of their own. DDOT has neither authority to plan nor money to build outside the District's boundaries.

So for now, DDOT is keeping its options open. But eventually they'll need to make a decision. At this point, it's on Maryland to come to the table.

Will there be dedicated lanes, and if so, where?

Whether or not the streetcar will have dedicated lanes depends on two factors: Is there adequate width on the street, and is there enough political support to repurpose lanes from cars?

The first factor is easy. This chart shows potential street cross-sections, color-coded to match street segments along the route alternatives maps.


Potential street cross-sections, color-coded to the map above. Image from DDOT.

Streets color-coded as either purple or blue are wide enough to potentially fit dedicated lanes. Streets coded as green, yellow, or orange are not.

The political factor is harder. Depending on the location, providing dedicated streetcar lanes might mean eliminating or reducing on-street parking, pushing truck loading onto side streets, or any number of other trade-offs.

DDOT's ridership forecasts say shaving 5 minutes off streetcar travel time would boost ridership 11%. If true, that suggests thousands more people would ride a streetcar with dedicated lanes than without.

And of course, the inverse is true too: Without dedicated lanes, many riders who could be on the streetcar might instead opt to drive.

At public meetings last week, representatives from the Georgia Avenue business community voiced strong objections to dedicated lanes, fearing that loss of parking would hurt their stores. But if dedicated lanes add more streetcar riders to a block than they remove parking spaces, the reverse could very well be true.

Is there money to actually build anything?

Thanks to Chairman Mendelson and the DC Council cutting streetcar funding in the latest budget, the DC budget currently doesn't have any funding for this line.

The council could add more money in future budgets, or DDOT could seek alternate funding options like the federal New Starts program. But for now, this line is unfunded and there's not yet a clear plan to change that.

In the meantime, DDOT will continue to plan, with the next step being an environmental study. But all other details pale next to the overarching and unanswered question of how to fund whatever the studies recommend.

Politics


Montgomery District 5 candidates want growth and transit, but in different places

All of the candidates running for Montgomery County's District 5 council seat say they want to bring jobs, shopping, and transit to an area that's long awaited them. But they seem to disagree on whether that investment should go where it's most needed, or where there's the least resistance.


District 5 is in light blue on the east side of the county.

Councilmember Valerie Ervin's resignation last fall left an open seat in Montgomery County's District 5, newly redrawn in 2010 to cover a narrow strip from Silver Spring to Burtonsville. Several candidates jumped in to succeed her.

Joining former journalist Evan Glass, who'd already announced before Ervin resigned, are state delegate Tom Hucker, Board of Education member Chris Barclay, community organizer Terrill North, and preacher Jeffrey Thames.

The majority-minority district struggles with poverty and disinvestment, and has some of the county's highest rates of transit use and lowest rates of car ownership. In ACT's questionnaire and in public forums, candidates said those issues are why the area needs
more transit and economic development.

Candidates want to build near transit, but some aren't sure about actual plans

Most candidates say they support building near transit, notably in downtown Silver Spring, home to the one of the region's largest transit hubs. Glass, who lived in downtown Silver Spring until 2012 and helped start the South Silver Spring Neighborhood Association, supports more development there as a way to preserve other areas and provide more affordable housing.

He's also called for reforms that could help local businesses and draw younger residents. Last month, he wrote an op-ed in the Washington Post with restaurant owner Jackie Greenbaum about the need to reform the county's liquor laws.

Other candidates have been reluctant to embrace specific projects that have faced resistance. At a Conservation Montgomery forum last month, Tom Hucker said the council should have never approved the Chelsea Heights development 5 blocks from the Metro station because it required cutting down old-growth trees.

Meanwhile, candidates have endorsed bringing more investment to Burtonsville's dying village center, 10 miles north. Residents generally support that idea, and State Delegate Eric Luedtke, who lives in Burtonsville, has called on District 5 candidates to start talking about it more.

Candidates have also touted the county's White Oak Science Gateway plan, which envisions a new research and technology hub surrounding the Food and Drug Administration headquarters alongside a town center containing shops and restaurants. The White Oak plan has considerable community support, but is tied up due to concerns about car traffic.

"If we don't build it in White Oak," said Hucker at a candidates forum in Briggs Chaney last week, "those jobs are going to go to Konterra [in Prince George's County], they're going to go to Howard County, they're going to go to DC."

Backtracking on transit

At the core of the White Oak plan are three planned Bus Rapid Transit corridors, on Randolph Road, New Hampshire Avenue, and Route 29, which the county will start studying in detail soon. All of the candidates say they support BRT, and Glass has been vocal about giving buses their own lanes, even if it means repurposing general traffic lanes. "Efficient and timely travel can only be achieved through dedicated lanes," he wrote in his questionnaire.

But others have offered reservations, especially in Four Corners, where a small group of neighbors have fought it for years. Hucker says he supports BRT "in certain places where it makes sense," and wants to focus in fixing Ride On first. "I don't support building BRT on the backs of our current Ride On or Metrobus," he said at a recent forum in Four Corners.


Terrill North. Photo from the candidate website.

Terrill North wants BRT on New Hampshire Avenue and on Route 29 north of White Oak, but not on Route 29 in Four Corners, which would be the most direct route to Silver Spring. "I don't think we need to take away curbs or take away business from this community, take away business from this community, take away lanes, because I think that could make things worse," he said at the same forum.

Likewise, all five candidates have endorsed the Purple Line, which could break ground next year. Hucker has long supported the light-rail line between Montgomery and Prince George's counties, and represents the General Assembly on Purple Line Now!'s board.

Meanwhile, North and Chris Barclay have expressed reluctance about developing around future Purple Line stations, like in Long Branch, citing concerns about higher density and the potential impacts to affordable housing and small businesses.

Strong support for complete streets

With a state highway as its spine, District 5 can be a dangerous place for a pedestrian, with lots of busy road crossings and fast-moving traffic. All candidates have said they support making our streets safer for pedestrians, cyclists, and transit riders.


Jeffrey Thames. Photo from the candidate website.

At the Four Corners forum and other events, Jeffrey Thames said he'd like to see more Barnes Dance intersections, like the one at 7th and H streets NW in the District, where pedestrians can cross in all directions. When asked if they'd support pedestrian- and bicyclist-friendly streets even if it slowed drivers down, Glass, Hucker, and North all said yes.

After years of watching the rest of Montgomery County draw jobs and investment, it seems like it might finally be East County's turn. Whoever represents the area next will get the chance to determine whether the area can give its residents, especially those of limited means, the investment they want, or if it continues to be a pass-through on the way to other destinations.

Full disclosure: Dan Reed is a member of One Montgomery, an organization that has endorsed Evan Glass, and has contributed to Glass's campaign.

Development


Single-family homes are the minority in Montgomery County

People often think of Montgomery County as a place where you go to buy a big house with a yard, and in many areas that's still the case. But most households live in townhomes or apartments, and that share will only increase in the future.


Montgomery's housing stock is getting more diverse. Photo by the author.

There are nearly 376,000 homes in Montgomery County according to the 2008-2012 American Community Survey. Less than half, or 48.5% are single-family detached homes. One out of three homes are apartments or condominiums, while another 18.2% are "single-family attached" homes such as twins and townhouses.

But different kinds of homes are clustered in different parts of the county. Single-family homes predominate on the more affluent west side and inside the Beltway. Townhouses are more common in newer neighborhoods far outside the Beltway, while apartments cluster along the Red Line and in farther-out areas.

Single-family homes spread out around the county

Not surprisingly, single-family homes predominate on Montgomery County's rural fringe, and in suburban areas. In several neighborhoods, particularly west of Rock Creek Park and in the far northern part of the county, single-family homes are the only type of housing, such as Parkwood in Kensington, Rollingwood in Chevy Chase, and the Town of Chevy Chase itself. 99.5% of all homes in Bethesda's Bradley Manor, recently named the nation's second-wealthiest neighborhood, are detached houses.

Single-family homes are also very common in older neighborhoods inside the Beltway, which were built early in the 20th century when the county first began suburbanizing. Today, they sit in close-in, highly coveted locations, very close to Metro stations and major job centers. Meanwhile, farther-out areas have a much more diverse mix of housing.

Townhouses are far beyond the Beltway

If you're looking for a townhouse, you may have to look far beyond the Beltway. The county's largest concentrations of attached homes are in parts of Germantown and Montgomery Village, where townhouses comprise over 70% of all homes. Other areas include Westlake, next to Montgomery Mall in Bethesda; Dalewood Drive, across from Wheaton High School, and Westfarm in White Oak.


Areas with a concentration of townhomes. All images by the author.

Why is this? The county's 1958 zoning code and subsequent 1964 General Plan established specific "urban" areas where townhomes and apartments would go. Meanwhile, older, close-in neighborhoods began fighting the construction of anything that weren't big, expensive single-family homes. So townhouses got built farther out, where land was cheap and the zoning allowed them.

Apartments hug the Red Line & sprawl outward

Multi-family homes in Montgomery County tend to fall into one of two camps. You'll find clusters of them around Red Line stations, especially in Silver Spring, Bethesda, and White Flint. These are usually high-rise and mid-rise buildings, and they're often more expensive. The rest are mainly cheaper garden apartments outside the Beltway in areas like Briggs Chaney, Aspen Hill, and parts of Gaithersburg.


Areas with a concentration of multi-family homes. All images by the author.

Notably, areas with the highest concentrations of apartments also have a lot of young people, a high rate of transit use, and a low rate of car ownership. But those living in apartment clusters farther out don't have the same access to shops, jobs, and transit as those in areas like Bethesda or Silver Spring. Creating more town centers in other parts of the county, like at White Oak, will allow those residents to have more access to economic opportunities.

Multi-family homes are the county's future

Single-family homes are still the most common housing type in Montgomery County, and more will continue to be built. But they'll make up a decreasing share of the county's housing stock. Between rising housing costs, increasing traffic, and a diversifying population that's also getting older, there's a growing demand for different housing choices.


Single-family homes like this one in Olney are still being built, but not as many as there were.

As of this April, there were 36,038 approved but unbuilt homes in the development pipeline, most of which will be built in town centers like Silver Spring or Bethesda or in Clarksburg, the county's one last greenfield area. Just 8,644, or 24% will be single-family detached homes or townhomes. And that doesn't include homes that are allowed under zoning but haven't been approved.

This is a big shift for Montgomery County. While the county has sought to concentrate growth near downtowns and transit lines since the 1960's, many residents and community leaders still think of it as an exclusively suburban place. But in the coming years, the definition between city and suburb will continue to blur.

Transit


A bridge closure suggests how bus lanes could affect traffic

Skeptics of Montgomery County's proposal to put bus lanes on major roads fear it could make traffic worse. But a road closure on Route 29 to repair recent storm damage might offer a glimpse of our possible future.


Image from SHA.

Two weeks ago, a torrential rainstorm flooded Route 29, also known as Columbia Pike, on a bridge where it crosses Northwest Branch in Silver Spring. This isn't the first time the bridge has flooded, and soon after, Maryland State Highway Administration closed the heavily damaged right lanes from Southwood Avenue to Lockwood Drive. Last Monday, it began making repairs, which will last until the end of May.

Montgomery County's Bus Rapid Transit plan envisions a line on Route 29 between Burtonsville and Silver Spring, which is already one of the region's busiest transit corridors, with 40 buses an hour during rush hour. Along most of the corridor, buses would have their own lanes, though we don't know if they would be on the curb or in the median, or if there would be a a reversible lane or lanes in both directions.

In any case, creating bus lanes would mean closing a lane to cars, which some residents in nearby Four Corners are vehemently opposed to. Thanks to last month's storm, we now get to see what closing a lane on Route 29 to general traffic might be like.

I've driven and taken the bus through the affected area a few times, including in evening rush hour. And there is some congestion, especially where drivers have to merge from three lanes to two. But the real test is what happens after people adjust to the new traffic pattern.

Studies have shown that taking away street space, often predicted to cause traffic mayhem, can actually reduce congestion as people find alternate ways to get there. Since the closure began, I've experimented with different routes. I've taken the bus at times of day when I would normally drive because there would be less traffic. Meanwhile, the sidewalks are still open, and I've noticed more people walking or biking to and from Trader Joe's across the bridge.

That may not seem like a big deal, but it only takes a 5% reduction in traffic to cause a 10 to 30% increase in traffic speed, meaning only a few people have to change their behavior in order for everyone to have a faster trip. It also explains why major highway closures around the country, like Carmageddon in Los Angeles, didn't cause the traffic they were anticipated to.

Of course, this isn't a perfect trial. The buses still have to share the remaining two lanes of traffic with everyone else. Unlike other, larger highway closures, there isn't a campaign directing drivers to other routes or beefed-up transit service. And unlike a road washout, a bus lane will give drivers another travel alternative to choose from instead of simply taking away street space.

But if Route 29 travelers can handle losing a lane for a few weeks, when the bridge is repaired, we might be able to do another trial with an actual bus lane.

Parking


Thousands of public parking spaces in Bethesda and Silver Spring sit empty every day

Ask someone about driving in Bethesda or Silver Spring on a weekend night and he or she will give you a mouthful: "There's nowhere to park!" But as those communities have grown, their parking demands have actually gotten lower. On an average day, thousands of spaces there sit empty.


Montgomery's downtowns have lots of empty parking spaces. Image by the author using data from MCDOT.

This Friday, transportation planner Tom Brown and I will talk about parking and placemaking at Makeover Montgomery II, a conference about strategies for urbanizing suburban communities organized by the Montgomery County Planning Department and the University of Maryland. In 2011, Brown led a team at Nelson\Nygaard, where I now work, that recommended ways Montgomery County could better use its parking to promote and strengthen its downtowns.

Montgomery County has had its own municipal parking authority since the 1940s. A 1952 spread in the Washington Post's "Silver Spring Advertiser" section boasted, "Look at all the parking space!" in downtown. But downtown Silver Spring couldn't match the sea of free parking at new suburban malls like Wheaton Plaza, and it began to languish.


1952 Washington Post article about all the parking in Silver Spring.

Many communities around the country faced the same story, especially older suburban communities that have more in common with revitalizing inner-city neighborhoods than in greenfield developments on the fringe. Yet these older suburban communities often have the power of place: unique, local shops and businesses, walkable streets, and vibrant public spaces. Today, people will eagerly deal with the hassle of parking to visit places like this and, increasingly, to live in them.

When Silver Spring started competing on place, not parking, it started to take off as an urban destination for the entire region. And a funny thing happened: as more homes and offices and shops were built around the Metro station, filling downtown's gaps and vacant lots, the demand for parking actually decreased.

According to the Montgomery County Department of Transportation, the demand for parking in Silver Spring actually peaked in the early 1980s, when it had fewer residents and jobs. Today, a majority of downtown residents get to work without a car. Over 40% of downtown's 9500 parking spaces are vacant all the time.

Realizing that its parking policies needed to reflect how people actually got around in its downtowns, county officials asked Nelson\Nygaard to offer suggestions. The resulting Montgomery County Parking Policy Study recommended reducing or eliminating parking requirements in urban areas, since there was already a glut of parking spaces, and finding ways to direct drivers to underused lots and garages.

Officials are starting to take the advice. Last year, the county passed a new zoning code that still mandates parking in new developments near transit stations, but requires far fewer spaces than it does for more suburban, car-dependent areas. That will conserve land and reduce building costs, as structured parking garages are very expensive to build lowering the barrier for potential residents and businesses who want to come here.

Meanwhile, the Department of Transportation has introduced demand-based pricing in Bethesda, setting higher rates for on-street parking spaces and lowering them in garages to encourage drivers to park there instead. This frees up on-street spaces for drivers staying for brief periods; reduces circling for a space, which causes congestion; and sends a message to drivers that they'll be able to find a space.

People will choose to live, work, and hang out in Montgomery County's downtowns not because it's easy to park there, but because they're great places to be. Some parking will be necessary, but these places will thrive if our community leaders focus on urban design and create complete streets that welcome everyone who already comes to Silver Spring or Bethesda by foot, bike, or transit.

Makeover Montgomery II runs from this Thursday through Saturday at the Silver Spring Civic Building in downtown Silver Spring. We'll be part of a panel discussion this Friday afternoon at 1:45 pm. For more information or to register, visit the conference website.

Three ways to build in Forest Glen without creating more traffic

As new homes, offices, and shops sprout around the region's Metro stations, Forest Glen has remained a holdout due to neighborhood resistance to new construction. But that may change as WMATA seeks someone to build there.


Metro wants to redevelop this parking lot. All photos by the author.

Last month, the agency put out a call for development proposals at Forest Glen, in addition to West Hyattsville and Largo Town Center in Prince George's County and Braddock Road in Alexandria. WMATA owns 8 acres at Forest Glen, most of which is a parking lot, and developers have already expressed interest in building there.

Forest Glen should be a prime development site. While it's on the busy Red Line, it's one of Metro's least-used stations. It's adjacent to the Capital Beltway and one stop in each direction from Silver Spring's and Wheaton's booming downtowns. Holy Cross Hospital, one of Montgomery County's largest employers with over 2,900 workers, is a few blocks away. But since Forest Glen opened in 1990, not much has happened.

On one side of the Metro station is a townhouse development that's about 10 years old, while across the street are 7 new single-family homes. The land the parking lot sits on is valuable, and it's likely that WMATA will get proposals to build apartments there because the land is so valuable. But zoning only allows single-family homes there, the result of a 1996 plan from Montgomery County that recommends preserving the area's "single-family character," due to neighbor concerns about traffic.


Townhouses next to the Forest Glen parking lot.

As a result, whoever tries to build at Forest Glen will have to get a rezoning, which neighbors will certainly fight. It's true that there's a lot of traffic in Forest Glen: the Beltway is one block away, while the adjacent intersection of Georgia Avenue and Forest Glen Road is one of Montgomery County's busiest. While traffic is always likely to be bad in Forest Glen, though by taking advantage of the Metro station, there are ways to bring more people and amenities to the area without putting more cars on the road.

Make it easier to reach Metro without a car

Today, two-thirds of the drivers who park at Forest Glen come from less than two miles away, suggesting that people don't feel safe walking or biking in the area. There's a pedestrian bridge over the Beltway that connects to the Montgomery Hills shopping area, a half-mile away, but residents have also fought for a tunnel under Georgia Avenue so they won't have to cross the 6-lane state highway.

Montgomery County transportation officials have explored building a tunnel beneath Georgia, which is estimated to cost up to $17.9 million. But county planners note that a tunnel may not be worth it because there aren't a lot of people to use it.

And crossing Georgia Avenue is only a small part of the experience of walking in the larger neighborhood. Today, the sidewalks on Forest Glen Road and Georgia Avenue are narrow and right next to the road, which is both unpleasant and unsafe. WMATA has asked developers applying to build at Forest Glen to propose ways to improve pedestrian access as well, and they may want to start with wider sidewalks with a landscaping buffer to make walking much more attractive. Investing in bike lanes would also be a good idea.

Provide things to walk to

Another way to reduce car trips is by providing daily needs within a short walk or bike ride. The Montgomery Hills shopping district, with a grocery store, pharmacy, and other useful shops, is a half-mile away from the Metro. But it may also make sense to put some small-scale retail at the station itself, like a dry cleaner, coffeeshop or convenience store, which will mainly draw people from the Metro station and areas within walking or biking distance. Some people will drive, but not as many as there would be with larger stores.

Putting shops at the Metro might also encourage workers at Holy Cross to take transit instead of driving, since they'll be able to run errands on their way to and from work. Encouraging this crowd to take transit is important, since hospitals are busy all day and all week, meaning they generate a lot of demand for transit, making it practical to run more buses and trains, which is great for everyone else.

Provide less parking

Whatever gets built at the Metro will have to include parking, not only for commuters, but for residents as well. While Montgomery County's new zoning code requires fewer parking spaces, each apartment still has to have at least one parking space. Even small shops will have to have their own parking. The more parking there is, the more likely residents are to bring cars, which of course means more traffic.

Thus, the key is to give future residents and customers incentives to not drive. The new zoning code does allow developers to "unbundle" parking spaces from apartments and sell or rent them separately. Those who choose not to bring cars will then get to pay less for housing. The code also requires carsharing spaces in new apartment buildings, so residents will still have access to a car even if they don't have their own. If Montgomery County ever decides to expand Capital Bikeshare, the developer could pay for a station here.

And the developer could offer some sort of discount or incentive for Holy Cross employees to live there, allowing hospital workers to live a short walk from their jobs.

No matter the approach, there are a lot of ways to build in Forest Glen without creating additional traffic. A creative approach can do wonders for the area's profile and elevate the quality of life for residents there.

Behold how the Purple Line corridor is changing

When built, the Purple Line could dramatically improve transit commutes in Montgomery and Prince George's counties. To explore that and other changes the line will bring, researchers created a series of maps including this one of the "commute shed" of each Purple Line station, or how far you can get on transit before and after it's built.


All images from the Purple Line Corridor Coalition.

Two weeks ago, the Purple Line Corridor Coalition organized a workshop called "Beyond the Tracks: Community Development in the Purple Line Corridor" to bring different stakeholders together and talk about ways to prepare for changes along the future light-rail line between Bethesda and New Carrollton, which awaits federal funding and could open in 2020.

The coalition is a product of the National Center for Smart Growth at the University of Maryland, which hosted the workshop. Members of the group include nonprofit organizations, developers, and local governments in Montgomery and Prince George's counties. At the workshop, they looked at examples from cities like Minneapolis and Denver, which recently built light-rail lines.

The 16-mile corridor contains some of the region's richest and poorest communities, in addition to major job centers and Maryland's flagship state university. When it opens in 2020, the Purple Line will help create the walkable, urban places people increasingly want. However, rising property values could potentially displace small businesses and low-income households. To illustrate and explore these issues, the Center for Smart Growth produced a series of awesome maps.

Like the DC area as a whole, the Purple Line corridor is divided from west to east, with more jobs and affluence on the west side, and more low-income households on the east side. Many of the estimated 70,000 people who will ride the Purple Line each day in 2040 will come from communities in eastern Montgomery and Prince George's county to jobs in Bethesda and Silver Spring.

But today, getting between those areas can be difficult and time-consuming, whether by bus or by car. It's no surprise that many commuters along the eastern end of the Purple Line have one-way commutes over an hour.

These maps, and the map above, show the "commute shed" of three Purple Line stations, or how far you can get on transit in an hour. In all three cases, the Purple Line opens up huge swaths of Montgomery, Prince George's and DC to each community. While the Purple Line only travels through a small portion of our region, it adds another link to our existing Metro and bus network, meaning its benefits will go way beyond the neighborhoods it directly serves.

But better access comes with a price, namely rising property values. The revitalization of downtown Silver Spring has resulted in higher home prices in surrounding neighborhoods because of the increased demand to live there. But Silver Spring and Takoma Park still have substantial pockets of poverty, meaning that low-income residents may not be able to afford to stay in the area once the Purple Line opens.

There are two ways to ensure that neighborhoods near the Purple Line remain affordable for both current and future residents. One is to protect the existing supply of subsidized apartments. Many complexes near the Purple Line have price restrictions for low-income households, but they will expire before it's scheduled to open in 2020.

The other is to build more new housing near the Purple Line. New homes are usually expensive, but increasing the supply of housing to meet demand can result in lower or at least stabilized prices. We're starting to see this in downtown Silver Spring, where thousands of apartments have been built in recent years. But Montgomery officials reduced the number of new homes allowed in Chevy Chase Lake and Long Branch due to concerns about changing the character of each neighborhood.

There are a lot of great and interesting communities along the Purple Line. But many of them are dramatically different places than they were even 10 years ago. They'll be different in 10 more years, whether or not the Purple Line is built. We can't preserve these places in stone, but we should try to ensure that the people who enjoy and contribute to these places can stick around in the future.
