Is there a Chipotle near my Red Line station?

Is there a Chipotle within a half-mile walk of my WMATA Red Line station?

In case you were ever curious about transit oriented burrito chains in the DC area:

chipotle red line

I’m not sure why I looked into this (besides having a burrito for lunch), but it seemed like many Red Line stations have Chipotles nearby. Indeed, 15 of the 27 Red Line stations have a Chipotle within a 0.5 mile walk (with #16 coming soon – in Brookland). Distances were determined by Google Maps walking directions with some minor adjustments.

As of June 30, 2015, there are 1,878 Chipotle restaurants in the world; 97 of those locations opened in 2015. Anywhere on the Red Line, you’re never more than three stops away from a walkable burrito chain. 14 of those are walkable to a Red Line station. A few Chipotle locations are the closest outlet for multiple metro stations (the closest location to Van Ness is the Cleveland Park Chipotle); at least one location (the 7th and G location) is the closest Chipotle to three different Metro stations (Metro Center, Gallery Place, Judiciary Square).

The award for the closest Chipotle to a Metro station entrance goes to Union Station, located just a few feet from the top of the escalators. Union Station also wins for having two Chipotle locations – with a recently-opened location in the station’s lower level food court.

 

Flipping Houses, Zoning Codes, and Building Codes

Earlier in May, local public radio station WAMU aired a lengthy three-part report on the collateral damage involved in house flipping in DC. Martin Austermuhle’s series offers a window into the nightmare for buyers of newly renovated homes – often converted from single family rowhomes into multi-unit buildings – who soon learn that their dream home is actually a nightmare of shoddy work and potentially illegal construction.

The three-part series focuses on buyers, developers, and the city’s regulatory response.

As horrifying as these stories are, Austermuhle correctly focuses on the challenges of enforcing the building code as the root cause of these problems, rather than the zoning code.

Small-scale development is an important tool in strong markets (like DC) to respond to demand for new housing. So many opportunities for small-scale urban development have already been regulated out of existence in American cities. The people buying these flips aren’t suckers taken by con men; they represent the market for additional housing in a city like DC.

Shoddy flips shouldn’t put those remaining opportunities for small-scale development in DC at risk, because the problem here is with building code enforcement and inspection, not with zoning. But whenever there is outrage, there is a strong urge for the city to do something, even if it doesn’t address the stated problem.

The zoning code is not the building code

Tales of illegal construction in flipped houses might stoke the fears of development opponents, but the problems described in the series involve errors in construction.

Too often, cities attempt to use the zoning code as a catch-all regulatory structure, encompassing economic development goals, social policy, etc. Part of this is out of convenience (I did have at least one proponent express support to me for DC’s recent zoning code changes in rowhouse neighborhoods due to the challenges in enforcing the building code – both for approvals and for construction inspections). I suspect part is also a confusion of the issues, thinking that because zoning deals with the city therefore zoning is an appropriate place for regulations about the city.

This series helps clarify the differences; Austermuhle correctly gives zoning only a cameo appearance.

Pop up limits

Even with the focus on building code enforcement, that doesn’t stop public calls to address development issues via zoning restrictions. However, it’s not clear that zoning would stop the flips. House flips are hardly limited to structures with the opportunity to increase the total number of units.

Enforcement matters:  One example of shoddy construction also includes blatant violations of the zoning code. What good will modestly tighter zoning regulations do without basic enforcement? Perhaps zoning isn’t the root problem; enforcement is.

Building codes matter

While zoning codes often get the attention, this doesn’t mean building codes aren’t important factors in determining the shape of the city. Houston famously (or infamously) lacks standard, use-based zoning codes. However, Houston’s building code and other regulations still mandate many of the aspects commonly found in zoning codes: minimum on-site parking requirements, minimum lot sizes, etc. It’s not a regulation-free environment.

Even when the building code sticks to more traditional subject matter, there can still be a tremendous impact on the financial feasibility of certain types of construction. In February, Let’s Go LA featured a guest post from LA Architect Tom Steidl about local differences in LA’s high rise building codes that make Vancouver-style towers less financially feasible:

Towers in Los Angeles tend to have significantly larger floor plates than those in Vancouver and US cities that have embraced high-rise design. The primary reason for this isn’t differences in land use or zoning codes. It’s mainly building code and fire department regulations that require additional floor area be added to the core of the tower. In addition to making our towers more bulky, this added floor area increases construction cost and reduces affordability.

One of LA’s quirks (now removed from the code) was a fire department mandate for rooftop helipads. But, as Steidl notes, each requirement that reduces the efficiency of the floor plate adds to the total cost. High rises are already expensive to build and will only pencil out under certain circumstances. Adding costs on the margins only makes the developer’s pro forma more challenging.

The building codes matter. But, LA’s quirky code provides a cautionary tale on policy relying on high rises alone to absorb housing growth. As Payton Chung has written, achieving mass market affordable housing via expensive construction types is a challenge – particularly in DC.

A comprehensive approach to affordable housing in strong markets like DC and LA can’t ignore the key role of small-scale, low-rise development in providing affordably built housing. This means projects of the type taken on by house flippers; smaller scale projects that increase a single lot into 2-4 units.

Poor construction risks eroding confidence in small-scale construction that is vital to meeting housing demand. Likewise, a strong, predictable, and nimble team of inspectors needs to effectively enforce DC’s building codes to manage this period of change.

Lawsuits: the American Way.

Maybe they will help. Writing about some of the same flippers as Austermuhle (and working in parallel), Ian Shapira at the Washington Post notes that some of the same flippers have been sued by DC’s newly elected Attorney General. A more robust consumer protection watchdog can’t hurt, and could even help jump-start a more robust system of code inspections.

Pop-ups – what counts as ‘reasonable?’

Beware the imperative that we have to do something.

Despite protestations from DC’s former planning director Harriet Tregoning, the preliminary vote count on the plan to limit rowhouse pop-ups in DC is poised to pass, 3-2 (note that two of the zoning commissioners tentatively in favor are the federal representatives to the commission; see this Washington City Paper profile of commissioner Peter May for more about the federal role in local decisions in DC).

Among the local media, the Washington Post editorial board came out against the proposed regulations. Other local papers, such as the Northwest Current, are in favor. The single biggest reason for supporting the proposed changes is that they seem ‘reasonable.’

IMAG2257

It’s not hard to see why many DC residents are eager for ‘reasonable’ restrictions on pop-ups. There are quite a few ugly ones out there; some include suspect construction. However, the proposed changes in the zoning code won’t outlaw ugly additions and the zoning code doesn’t regulate construction methods or enforce the building code.

Part of the challenge with ‘reasonable’ restrictions on new development is that many of the impacts aren’t intuitive. Consider the aesthetics of pop-ups: Just as zoning code parking requirements won’t solve on-street parking hassles (you must manage those parking hassles directly), a small reduction in the allowable height and shifting certain elements away from by-right construction towards requiring a special exception won’t address concerns about design. Implement these changes to DC’s zoning code and many will still complain about pop-up development.

Pop-ups need not be ugly. Nor are they a new phenomenon.

Part of the concern about overly restrictive regulations is that limiting small-scale development is a serious constraint on the market’s ability to provide housing that is affordable to a wide range of incomes (here’s a perfect place to shift the narrative away from the nebulous ‘affordable housing’ and instead focus on providing abundant housing instead).

Still, without that background knowledge, it’s not hard to think that these restrictions won’t harm the District’s progress towards abundant housing. Proponents of allowing more growth argue pop-ups provide an opportunity for families and individuals to live in desirable neighborhoods at a lower price point. Meanwhile, the Northwest Current editorial board isn’t convinced that allowing additional housing supply helps ease the supply crunch. Instead, they would wish housing prices would drop naturally:

IMAG2256

However, the flip side of the “we’d rather just see the existing houses priced more affordably” coin is essentially an argument to lower property values. I don’t think we’ll see such an editorial from the Northwest Current anytime soon. Why? Because I doubt neither the editorial board nor the paper’s readership would consider advocacy to lower property values to be ‘reasonable.’

So, what are options to regulate pop-ups? A few ideas, keeping in mind the differing perspectives and scales)

  • Recognize the value of by-right development and the path of least resistance. Similarly, the idea of negotiating every single building project on a case-by-case basis might also seem reasonable, beware the unintended consequences of this approach.
  • Consider a form-based approach. The Coalition for Smarter Growth suggested an approach that mandates a setback for true pop-ups (those that retain the existing facade) or some other design treatment to minimize the visual impact. The challenge for this approach would be in enforcement. The advantage is that the regulatory authorities can offer clear guidance for this form of ‘lite’ administrative design review. It also avoids the perils of full-scale design review; a process that doesn’t keep the desired outcomes on the path of least resistance.
  • Remember: one of the goals of DC’s pending zoning code re-write was to reduce the burden on the BZA’s case load. Simply adding more cases to the pool of potential special exceptions is a step in the opposite direction.
  • Build more rowhouses. Part of the rationale for regulating pop-ups is a desire not just to preserve the urban design of DC’s rowhouse neighborhoods, but also to preserve larger housing units for families. If this is indeed a goal for the city’s housing strategy (and consistent with the desires for abundant housing), then the goal shouldn’t just be about preserving rowhouses, but encouraging the construction of more of them in existing single-family detached areas. This is also consistent with the city’s goals for accessory dwelling units as a part of the zoning re-write.
  • Build more multi-family housing. Work to relieve development pressure from the other end by allowing the construction of more small-scale apartment and condo buildings. DC has many of these grandfathered into existing R-4 (rowhouse) zones. While the Comprehensive Plan does prioritize the preservation of rowhouse areas, the existing zoning clearly allows multi-unit buildings. While much of the commentary focuses on micro effects and ugly additions, lurking beneath the surface is a clear bias against additional dwelling units. This backlash mirrors other DC planning debates about accessory dwelling units and growth in general.
  • Develop a market-based housing plan for the city as a whole. Collect and distribute data on the overall housing market to better inform decisions on demand as well as new supply.
  • Shift the narrative around housing discussions away from ‘affordable housing’ and towards ‘abundant housing.’ Hopefully this shift can help avoid the counterfactual trap of new supply that is still expensive, yet cheaper than it would’ve been. Consider this: if car manufacturers could only build a limited number of cars, they would likely focus on higher-margin luxury models. The same is true of housing; yet this doesn’t disprove the impact of supply.  Just because new condos in popped-up buildings aren’t always cheap, that doesn’t mean the impact on the overall market isn’t real.

Any other ideas?

Decreasing opportunities for incremental development in American neighborhoods

Several months ago, Charlie Gardner had an excellent, thought-provoking post asking why have American cities seen the demise of the duplex? In a time when growing cities are bursting at the seams and facing severe affordability challenges, an incremental kind of development might be welcome in many cities, offering new housing while allowing an evolutionary pace of change to a neighborhood’s physical fabric, instead of the abrupt transition of large-scale redevelopment. So why don’t we see more of it?

Consider international comparisons of small-scale incremental development: Charlie Gardner compares the built form on both sides of the US-Mexico border, noting how on the Mexican side houses grow incrementally over time, often adding new uses along the street. The net result is a slow transformation of the entire neighborhood, evolving towards denser development patterns. Gardner speculates on reasons for the difference with standard American development patterns (including finance and regulation), noting that the small-scale development open the door to homeownership at a much lower price threshold.

Conversely, there are examples of American neighborhoods adding units on a relatively small scale. Let’s Go LA has been tweeting highlights from Wallace Frances Smith’s “The Low-Rise Speculative Apartment,” published in 1964. The book documents the replacement of single-family homes with low-rise speculative apartments (often in the form of dingbats), concluding that this small-scale, relatively low-cost form of construction plays an important role in adding housing supply to the market. Without requiring challenging lot consolidation or more-expensive construction methods, this kind of incremental, small-scale development allowed neighborhoods of single-family homes to evolve into denser places – even without large incomes in the neighborhoods to afford expensive new construction.

Despite the small scale of each individual building, the net result was a substantial increase in housing production overall.

So, why don’t we see more of this today? While various New Urbanists might not like the specific dingbat product, the idea of small-scale urban density is still appealing. The so-called ‘missing middle’ forms, such as townhouses, flats, and small apartment buildings are all lauded as contextually-friendly ways to add housing and increase density in already developed areas. So, why are these housing types missing?

As Let’s Go LA points out, much of this kind of development has been regulated out of existence. In LA, large portions of the city have been downzoned; the newer zoning no longer allows for by-right development of dingbats and other small-scale apartment buildings. In aggregate, the result is a huge decrease in the potential development allowed in LA.

Much of that LA zoning potential would’ve been in the hands of small-scale landowners rather than large real estate development firms. One consequence of removing that development potential is to erode the ‘franchise’ for incremental development. Let’s Go LA notes that “by zoning small developments out of existence, we’ve made land development a much less democratic process, in the sense that far fewer individuals in the community are able to participate economically.” Instead, 20% of LA’s recent growth has been absorbed in the relatively small confines of downtown. While this is good for downtown (thanks to regulatory changes such as LA’s adaptive re-use ordinance and relaxation of off-street parking requirements – discussed previously here), limiting growth to such a small area of the city has consequences: “when growth is restricted across so much of the rest of the city, there will still be pressure on regional housing prices, and gentrification will continue.”

The phenomenon isn’t limited to LA or to dingbats. Stephen Smith, writing at New York YIMBY, looks at the demise of small-scale development (buildings smaller than five units) in New York: “Put simply: New York City’s small builders have been nearly eradicated. The segment of the market that normally produces about half the city’s new building stock has all but vanished.”

Smith considers several hypotheses for this decline in small-scale development, including the end of some tax abatement programs and weak markets in some parts of the city. Smith also hypothesizes that New York’s recent ‘contextual rezonings’ removed development potential from areas ripe for small-scale development:

The result is that many neighborhoods that were once full of redevelopment opportunities are now closed off to anything but the smallest of one- or two-family projects on vacant lots. This sort of redevelopment was largely banned after the implementation of the 1961 zoning code, but throughout her tenure Amanda Burden closed off the last few areas where it was still allowed.

DC is seeing similar conversations. Demand for additional housing often leads to ‘pop-up’ development, often in the form of vertical additions to existing rowhouses. The term even gets used as a catch-all for any kind of smaller scale infill development. Many existing residents are concerned about the changes (though others are supportive).

Responding to political pressure and resident requests, the Office of Planning proposed their own version of a contextual rezoning.However, during a hearing on the measure, one of the zoning commissioners expressed deep concern about the overall impact of reducing this development potential in a city with a growing population and decreasing housing affordability. Greater Greater Washington’s summary of the exchange captures the concern: “I just don’t think we have a comprehensive housing policy in this city and I’m worried about all the unintended consequences of [this proposal].”

While Charlie Gardner contrasted American urbanism to Mexico, there are other options as well. This paper from Sonia Hirt looks at German land use regulations. German zoning is guided by federal standards, localities have some flexibility within those standards but cannot add restrictions to the basic zoning classifications. One end result is that there is no such thing as a residential zone devoted solely to single-family homes. Likewise, even residential zones must accommodate commerce to meet the “daily needs” of the neighborhood.

In outlining potential routes for zoning reform in the United States building off of lessons learned from Germany, Hirt suggests that instead of relatively small areas of mixed-use zoning, planners could focus on a wider area of limited flexibility for residential development – something that might not look that different from the small, speculative apartment developments of the 50s and 60s; or of duplex development.

The zoning straightjacket

The more things change, the more they remain the same.

DC is nearing the end of a lengthy process to re-write the city’s zoning code. The re-write is mostly a reorganization, combining overlays and base zones in an effort to rationalize a text that’s been edited constantly over the better part of half a century. While there are a number of substantive policy changes (all good and worth supporting – reducing parking requirements, allowing accessory dwelling units, allowing corner stores, etc.), the intent of the re-write is to look at the structure and policy of the code, rather than look for areas of the city where the zoning classification should change.

Actual re-zoning will require an update to the city’s comprehensive plan (as all zoning changes must be consistent with the comprehensive plan). As promising as the policy changes in the zoning re-write may be, they do not represent any kind of change to the basic city layout – areas currently planned for high density will see more development, and areas zoned for single-family homes will not.

Last year, the District Government and the National Capital Planning Commission worked on dueling reports (see the documents from DC and NCPC) at the request of Congress on the potential for changing DC’s federally-imposed height limit. Leaving aside the specific merits and drawbacks of this law, the planning team needed first to identify areas that would likely see taller buildings if the height limit were to change.

I’ve borrowed the title of this post from Charlie Gardner, to try to show how little room we’ve planned in our cities for change. Even with the perception of runaway development in growing cities, the amount of space that’s set aside for a physical transformation is remarkably small. Zoning is a relatively new force shaping our cities – about a century old. We’re now seeing the effects of this constraint.

Consider the following examples of freezing city form in place via zoning codes:

Old Urbanist – The zoning straightjacket, part II, writing about Stamford, Connecticut:

In general, the zoning maps continue to reflect the land use patterns and planning dogma of the 1920s, with a small, constrained downtown business district hemmed in by single-use residential districts through which snake narrow commercial corridors.

This, if nothing else, seems like a fundamental, if not the only, purpose and challenge of city planning: accommodating population growth in a way that takes into account long-term development prospects and the political difficulty of upzoning low-density SFD areas. In light of this, can a zoning code like Stamford’s, with a stated purpose of preserving existing neighborhoods in their 1960s form, and resistant to all but changes in the downtown area, really be called a “planning” document at all? The challenges that Stamford faces are not unique, but typical, and progress on them, as zoning approaches its 100th birthday, remains the exception rather than the rule.

Better Institutions – Look at the Amount of Space in Seattle Dedicated to Single-Family Housing, writing about Seattle:

Putting aside the issue of micro-housing and apodments, [ed – I wrote about Seattle’s apodments here] what I’d actually like you to draw your attention to is everything that’s not colored or shaded — all the grey on that map. [ed – here is a link to the map] That’s Single-Family Seattle. That’s the part of the city where most people own their homes, and where residents could actually financially benefit from the property value-increasing development necessary to keep Seattle affordable. It’s also the part of the city that’s off-limits to essentially any new residential construction because preserving single-family “character” is so important. And it’s why residents in the remaining 20% of the city can barely afford their rents.

Dan Keshet – Zoning: the Central Problem, in Austin, Texas:

Zoning touches on most issues Austin faces. But with these maps in mind, I think we can get more specific: one of the major zoning problems Austin faces is the sea of low-density single-family housing surrounding Austin’s islands of high residential density.

Daniel Hertz – Zoning: It’s Just Insane, in Chicago, Illinois:

So one thing that happens when I bring up the fact that Chicago, like pretty much all American cities, criminalizes dense development to the detriment of all sorts of people (I’m great at parties!) is that whoever I’m talking to expresses their incredulity by referencing the incredible numbers of high-rises built in and around downtown over the last decade or so. Then I try to explain that, while impressive, the development downtown is really pretty exceptional, and that 96% of the city or so doesn’t allow that stuff, or anything over 4 floors or so, even in neighborhoods where people are lining up to live, waving their money and bidding up housing prices.

Chris D.P. – The High Cost of Strict Zoning, in Washington, DC:

Across town, the Wesley Heights overlay zone strictly regulates the bulk of the buildings within its boundaries for the sake of preserving the neighborhood character.  Is it ethical for the city government to mandate, essentially, that no home be built on less than $637,500 worth of land in certain residential neighborhoods?

The largest concentration of overly restrictive zoning (from an economic perspective) appears to be downtown, along Pennsylvania Ave and K Streets NW. If we value our designated open spaces, and won’t concede the exclusivity of certain neighborhoods, but understand the environmental and economic benefits of compact development, then isn’t downtown as good a place as any to accommodate the growth this city needs?

DC’s height study shows a similar pattern. The very nature of the thought exercise, the hypothetical scenarios for building taller and denser buildings in DC requires first identifying areas that might be appropriate for taller buildings. As a part of this exercise, the DC Office of Planning identified areas not appropriate for additional height based on existing plans, historic districts, etc.

These excluded areas included: all federal properties, all historic landmarks and sites; low density areas in historic districts; all remaining low density areas, including residential neighborhoods; institutional sites and public facilities. Those areas are illustrated in the Figure 4 map below. The project team determined that sites already designated as high and medium density (both commercial and residential) were most appropriate for the purposes of this study to model increased building heights because those areas had already been identified for targeting growth in the future through the District’s prior Comprehensive Plan processes.

Put this on a map, and the exlcuded areas cover 95% of the city: 

DC height act study no go

Now, this isn’t analogous to the comparsions to areas zoned for single-family homes in other cities, nor are all of the areas in red innoculated from substantial physical change. However, it does illustrate just how limited the opportunities for growth are. It broadly parallel’s the city’s future land use map from the Comprehensive Plan, where large portions of the city are planned for low/medium density residential uses (click to open PDF):

DC Comp Plan Future Land Use

The plan’s generalized policy map also illustrates the extent of the planned and regulatory conservation of the existing city form (click to open PDF):

DC Comp Plan General Policy

The areas without any shading are neighborhood conservation areas.

All of this should be reassuring to those concerned about the proposed zoning changes, since all changes must be consistent with the comprehensive plan.

Fearing ‘hyperdensity’ in urban areas

One of the books I picked up through the rounds of exchanging holiday gifts is Vishaan Chakrabarti’s A Country of Cities: A Manifesto for an Urban America. I’ve read an excerpt of the book published in Design Observer and watched Chakrabarti’s accompanying lecture; I’m looking forward to reading the full book.

In my initial reaction to the book’s excerpt embraced the praise for dense, urban, transit-supportive cities, but expressed concern about the political and regulatory hurdles to achieving such a vision. In particular, the ‘hyperdensity’ terminology Chakrabarti used to describe levels of density that can support subway transit seemed like it could directly antagonize citizens skeptical of change – citizens that currently hold the upper hand in many of the procedural and regulatory battles over new development.

Consider some of the reactions in Toronto. This op-ed from Marcus Gee in the Globe and Mail echoes Chakrabarti’s praise for urban density, but also shows the risk of the ‘hyperdensity’ terminology:

A spectre is haunting Toronto – the spectre of hyperdensity. Jennifer Keesmaat, the city’s dynamic chief planner, worries about it. So does one of Toronto’s smartest local politicians, city councillor Adam Vaughan…

[T]he city’s Official Plan seeks to direct new development – office buildings, condo towers and so on – to key areas of the city, fostering the process known in planners’ jargon as intensification. The aim is to put new buildings on about a quarter of the city’s geographical area, keeping the three-quarters that is left – residential neighbourhoods, quiet, smaller streets – free from runaway growth.

As anyone can see from the thickets of development around nodes like Union Station or Yonge and Eglinton, it has been remarkably successful – too successful for some. “We have reached this exciting and terrifying tipping point where we are starting to question whether it could be there is something called too much density,” Ms. Keesmaat said. “There are some areas of the city where we are seeing too much density – hyperdensity – and there are other areas of the city where we are seeing no growth at all.”

Here, the warnings about hyperdensity echo San Francisco’s concerns about “Manhattanization” – long-standing skepticism about growth and urban development with serious impacts on the city and region’s affordability over the past decade plus.

It would seem that Toronto’s plan is working exactly as intended: growth is channeled to some areas while it isn’t allowed to happen in others. Seeing little to no growth in areas of the city planned for little or no growth would all be according to plan.

This isn’t to say that the plan is wise. Trying to focus all growth in a city with high demand into downtown and a handful of mid-rise corridors might be too much of a constraint. It’s a strategy tailor-made to minimize conflict with the single-family neighborhoods, not dissimilar from Arlington County’s focus on Metro station areas while preserving single family homes nearby. It’s also one that bears a great deal of similarity to DC’s current discussions about how, how high, and where to grow. As Payton Chung notes, even this modest bargain is no guarantee to avoid conflict:

Among large North American cities, only Toronto has joined DC in making a concerted effort to redirect growth into mid-rise buildings along streetcar lines — and only as an adjunct strategy in addition to hundreds of high-rises under construction. (The two metro regions are of surprisingly similar population today.) Yet there, just like around here, neighborhoods are up in arms at the very notion.

Nor does it guarantee the city can actually match supply to demand:

DC cannot put a lid on development everywhere — downtown, in the rowhouse neighborhoods, in the single-family neighborhoods, on the few infill sites we have left — and yet somehow also accommodate enough new jobs and residents to make our city reliably solvent, much less sustainable. The sum of remaining developable land in the city amounts to 4.9% of the city, which as OP demonstrates through its analysis, cannot accommodate projected growth under existing mandates.

Something will have to give.

Toronto’s plan took the lid off in downtown, yet now the resulting development is derided as ‘hyperdensity.’ Marcus Gee notes that hyperdensity’s impact on infrastructure also provides the means to upgrade those facilities; build more transit; expand parks and urban amenities:

If the hyperdensity tag catches on, it could become a useful tool for downtown councillors who want to appease their constituents by blocking new development or for suburban councillors who want to steer more development to their wards even if there is no call for it there. It could also help kill exciting projects like the Frank Gehry-designed proposal by David Mirvish for King Street West. Ms. Keesmaat’s planning staff oppose the plan for three towers of more than 80 storeys each – too tall, too dense – and city council backed her up in a vote on Dec. 18.

It is reasonable to worry that new development will cause overcrowding on transit or overtax other city infrastructure. But if that is the concern, let’s build better transit to keep up with the growth, not halt the growth for fear of the future. Central Toronto is still far less dense than it could or should be. Hyperdensity should be a goal, not a thing to fear.

Emphasis added. This is the crux of my concern. How we frame the issue matters, even if the eventual solution won’t be about convincing the public of the virtues of hyperdensity and embracing it as a goal. Rather, achieving that goal will require reforming the processes and procedures for making decisions about land use and development.

I hope Chakrabarti’s book will touch on this; I look forward to reading it.

646,449 – DC’s population continues to grow

Cranes. CC image from Daniel Foster.

Cranes. CC image from Daniel Foster.

The latest state-level population estimates show another year of 2%+ growth for DC, bringing the city’s estimated population to 646,449. Former Mayor Tony Williams set a goal in 2003 of adding 100,000 new residents to the city back when the city’s population growth was essentially nil, following decades of population decline.

Even in the relatively short history of this blog, nearing the symbolic 600k threshold prior to the 2010 Census was a big deal.

Of the growth in the most recent estimates, about 1/3 of the gains are from natural increases in the population (births minus deaths), while 2/3rds are from net migration (more people moving into the city from elsewhere than moving out).

Explanations for DC’s recent growth spurt that focus on Federal government spending are tempting, but misleading. The region’s overall growth rate since World War II is fairly consistent; what’s changing now is how that regional growth is allocating itself within the region. Chris at R.U. Seriousing Me shows how DC’s share of the regional population decreased from 1950 to 2010. The region’s growth trajectory has been upward, while the District’s population declined. However, if you assumed that DC maintained the same regional share of that growth throughout the last half-century, you’d find a DC today with 2.6 million people inside the city limits.

The counterfactual scenario is intriguing: assume a DC population of 2.6 million still governed by the federal height limit, and suddenly the comparisons of DC to Paris (low-rise with high population density) aren’t so absurd. Chris notes that for those opposed to even modest changes to the height limit or the construction of by-right buildings, the kind of development needed to accommodate 2.6 million people “must sound apocalyptic.”

Leaving the apocalypse aside for the moment, the 2.6 million resident scenario illustrates that you must not only have demand for growth, but allow that growth to happen – that is, allow the city’s housing supply to increase. Again, a comparison to Paris is illustrative: the Paris region has continued to grow, while the city’s population has somewhat declined and flattened out. It’s not hard to see why; the city’s legal and regulatory constraints on development do not provide room to grow within the city.

Mayor Gray, like Mayor Williams, set an ambitious goal for growth the District’s population: adding 250,000 new residents by 2032. Unlike in 2003, it’s not hard to see the demand for city living – in fact, we’re on pace to meet that goal right now. If the city were to continue to grow by 13,000 per year (as it has over the past three) over twenty years, DC will hit that mark.

Demand is only half of the equation, however. Michael Niebauer notes that the population gains justify the increased development seen around DC, and more will be needed to accommodate increased demand for living in the city. If city does not add supply, the demand will continue  to put pressure on housing prices.

Tall buildings in European cities

While visiting Europe, I missed most of the local debate on potential changes to DC’s federally imposed height limit (see – and contrast – the final recommendations from the NCPC and DC Office of Planning, as well as background materials and visual modelling, here). But I sure didn’t actually miss any tall buildings; I saw lots of them in just about every city I visited (several of which are documented in NCPC’s selected case studies).

Some thoughts on three of the cities I visited:

London’s appeal for height is obvious, with skyscrapers emerging within the City of London. London has a sophisticated plan for managing heights, as explained by Robert Tavenor (transcript – slides) at NCPC’s event on building heights in capital cities (video available here), balancing London’s interest in quality of life, history, and the desire to maintain London’s status as a primary capital of the global world.

All of this planning effort focuses on the City of London, building upon the already existing transportation infrastructure while preserving specific view corridors, and ensuring that tall buildings that do break the existing skyline include high quality design and are clustered together in designated districts. Other such clusters exist outside of London’s center, such as Canary Wharf – more akin to the kind of cluster of tall buildings along the city’s periphery, as seen in La Defense outside of Paris.

Paris features a suburban cluster of skyscrapers, while the central city skyline remains almost uniformly flat. However, in recent years, the city has allowed taller buildings in the outer arrondissements. Socialist city officials pushed for additional height as part of a plan to increase housing supply and address housing affordability.

Comparing Paris to DC is superficially appealing. Paris’s almost absolute 37m limit (approx 120 feet) is similar to DC’s limit. NCPC’s summary of case studies highlight their lessons learned from Paris:

Paris demonstrates that restrictive building height controls can coexist with significant residential density. Among the case study cities, it has the greatest population density per square mile.

While this is true, it only highlights what is possible with a Parisian-style limit on height; it does not address what is required to achieve such residential densities. Payton Chung offered these comments on this blind spot in DC-Paris comparisons:

One oft-repeated line heard from the (small-c) conservative crowd is that height limits have worked to keep Paris beautiful. That comment ignores a lot of painful history: the mid-rise Paris that we know today was built not by a democracy, but by a mad emperor and his bulldozer-wielding prefect. As Office of Planning director Harriet Tregoning said in a recent WAMU interview, “Paris took their residential neighborhoods and made them essentially block after block of small apartment buildings… if we were to do that in our neighborhoods, we could accommodate easily 100 years’ worth of residential growth. But they would be very different neighborhoods.”

…

That path of destruction is why most other growing cities in this century (i.e., built-out but growing central cities, from London and Singapore to New York, Portland, Toronto, and San Francisco) have gone the Vancouver route and rezoned central industrial land for high-rises. This method allows them to simultaneously accommodate new housing, and new jobs, while keeping voters’ single family houses intact. By opposing higher buildings downtown, DC’s neighborhoods are opposing change now, but at the cost of demanding far more wrenching changes ahead: substantial redevelopment of low-rise neighborhoods, skyrocketing property prices (as in Paris), or increasing irrelevance within the regional economy as jobs, housing, and economic activity get pushed further into suburbs that welcome growth.

Another superficial point of comparison is in the effective height limit. While Parisian heights are capped at 120 feet and DC heights commonly max out at 130 feet, the exact mechanism for calculating those hieghts matters a great deal. The DC method, based on street width (height and street width in a 1:1 ratio, plus 20 feet), makes use of the extraordinarily wide streets provided by the L’Enfant Plan.

Paris has similarly broad avenues, but those avenues were carved through the existing cityscape (people often forget that the 1791 L”Enfant plan pre-dates the Haussmann renovations of Paris by half a century), and the absolute nature of the height limit allows for max-height buildings along the city’s narrow, medieval streets – with building height to street width ratios far in excess of DC’s 1:1 +20′.

Utrecht Centraal is the busiest rail station in the Netherlands. Thanks to the city’s location in the center of the country, frequent and fast rail connections are available to all points in the country. For pedestrians, the only connection to the medieval center of Utrecht is by walking through the 1970s-era Hoog Catharijne shopping mall. The entire station and adjacent areas are currently in redevelopment, upgrading the rail station to handle increased passenger volumes, restoring a historic canal, and providing room for new, tall development adjacent to the station.

Utrecht is not the only city in the Netherlands pursuing such a strategy. In Amsterdam, the Zuid and Bijlmer Arena stations feature substantial development and tall buildings; Rotterdam’s Centraal station is also a hub for a massive redevelopment project.

According to the Utrecht station area master plan, large areas around the station provide for a base height of 45 meters, with towers up to 90 meters (~300 feet), including the Stadskantoor pictured above. Even with that height, you rarely get a sense that such tall buildings exist. The city’s narrow streets (even with short buildings) constrain view corridors. Within the medieval city, the views you do see are mostly of the 368 foot tall Dom Tower, not of the buildings of similar height closer to the train station.

Link dump – all things ‘affordable housing’

I’ve got far too many tabs sitting open in my browser, awaiting some form of linkage in the blog (the dates of publication might show how long they’ve been sitting). But, I want to put some of these out there rather than hog my browser’s memory.

I’ve attempted to cluster them together topically – a whole host on affordable housing policies and market-rate development.

“Winning upzoning in the bay” – from PriceRoads.com. The paralysis of urban development is part of a procedural tragedy of the commons, a side-effect of the decision-making architecture that we’ve adopted over time.

I now believe that California is not especially resistant to change, but rather that we’re seeing the tragedy of the commons that results when unified housing market is divided into dozens of cities. In short: when each city constitutes a tiny fraction of the habitable part of the metro area, no city can individually change housing prices much by allowing more development, but it can control the crowding within its borders.

So, what’s a potential solution to this impasse? Just buy people off.

Maybe the best dollar-for-dollar policy initiative of our time was Race to the Top. For $5 billion, the Obama administration bribed hundreds of thousands of charter-school students into existence. Race to the Top gave a lot of firepower to charter school proponents, allowing them to accuse teachers of turning down money for students…reversing the normal debate in which charter schools are accused of sapping money from traditional public schools.

The best way to deregulate cities would be to bribe key constituencies in a way that gives easy fodder for debate. I propose the following: California should triple the solar tax credit for seniors in communities that substantially ease zoning regulations. Any deregulation policy has to neutralize the most ardent opponents of development: seniors and environmentalists. This one would not funnel money through bureaucrats and would show up in anyone’s pocketbook as soon as they asked for the solar panels.

“NIMBYism will lead to economic stagnation” – an Op-Ed in the SF Examiner

Instead of fostering policies that discourage job formation, real estate development and economic growth, policymakers should be encouraging greater densities, and greater heights for new housing, especially along BART and Muni lines. If we are to get more people to live and work in San Francisco, then we must reject NIMBYism as a selfish luxury we cannot afford. The City badly needs an expanding tax base to fund financial promises it has made to public employees and to pay for its essential municipal services. New developments add mightily to the public’s well-being through contributions to The City’s funds for affordable housing, parks, transportation and the like. All of this comes from economic growth and a sensible balance between what we are now and what we need to be moving forward.

“Report finds a city incentive is not producing enough affordable housing” – New York Times

The report… found that the optional program known as inclusionary zoning had generated about 2,700 permanently affordable units since 2005, or less than 2 percent of all apartments developed in the city during the same period.

Under the program, the city allows developers of market-rate housing to build more units than would normally be allowed when neighborhoods are rezoned for new development, as long as they make 20 percent of the new homes affordable.

But Bill de Blasio, the city’s public advocate, argues in his housing platform for “converting incentives to hard-and-fast rules,” saying that 50,000 additional affordable units could be built over 10 years with a mandatory program.

Mandatory IZ might not be the fix New York is looking for. DC has it, yet we’re still looking elsewhere for inspiration.

“In New York, the rent doesn’t have to be ‘too damn high’ “ – Reihan Salam in Reuters

A century later, neighborhoods like the one I grew up in seem frozen in amber. The faces are different, to be sure, and so are the languages spoken by the locals. Crime has gone down and property values have gone up, and New York City is as desirable as it’s ever been. Yet we’ve had nothing like the building boom of the 1910s and 1920s that transformed the face of the city. Millions of low- and middle-income New Yorkers thus find themselves squeezed by skyrocketing rents, and hundreds of thousands of others who want to make their home in New York can’t afford to do so.

…

The first and most obvious thing to do is to broaden area in which housing can be built. For example, Schleicher and Roderick Hills Jr. of New York University Law School observe that cities like New York use “non-cumulative zoning” to dedicate desirable locations to low-value industrial uses. They propose allowing developers to replace empty warehouses, barely-used shipping facilities, and heavily subsidized factories with housing. Historical preservation districts severely restrict new housing development in many of New York City’s most desirable residential neighborhoods, which has contributed to rising housing prices. Though hardly anyone proposes getting rid of historical preservation districts entirely, the Harvard economist Edward Glaeser has made a strong case for limiting their growth.

Is NYC “Landmarking Away” Its Future? – ArchDaily

A recent study by the Real Estate Board of New York (REBNY) concluded that by preserving 27.7% of buildings in Manhattan, “the city is landmarking away its economic future.” REBNY is challenging the Landmarks Preservation Commission, arguing it has too much power when it comes to planning decisions, and that by making business so difficult for developers it is stifling the growth of the city.

…

Preservation, on the other hand, limits new supply and also creates a ‘cultural commodity’ of preserved buildings, both of which would increase the cost of living. How is it, then, that Francis Morrone cites new development as part of the problem, rather than the solution to rising costs?

Quite simply, the members of REBNY are building the wrong type of development: where developers do get the opportunity to build without restriction, they are too often building luxury apartments that are only an option for the super-rich. This may be good for their short-term profit margins, but it is bad for the long-term vitality of the city, as those who are not astoundingly wealthy are forced to leave – and the city becomes less diverse and less productive as a result.

Both sides overplay their hand a bit here. Landmarking alone isn’t what constrains New York real estate development (nor is it the case in other cities), and other constraints are also what push market-clearing prices so high (hence why all new apartments seem to be luxury ones). Affordability over time also involves filtering – yesterday’s luxury apartments have filtered down to more affordable price points. If you don’t build enough housing, you’ll see those older buildings filter up.

“In Defense Of The ‘Poor Door’: Why It’s Fine For A Luxury Condo Developer To Keep Its Low-Income Units Separate” – from Josh Barro at Business Insider, where he goes through a thought experiment about applying the same logic of IZ to that of SNAP benefits.

We require and incent developers who build market-rate housing to also sell or rent some units in the same developments at cut-rate prices. The idea is that affordable housing shouldn’t just be affordable and livable; it should be substantially similar in location and character to new luxury housing. If rich people are getting brand new apartments overlooking the Hudson River, so should some lucky winners of affordable housing lotteries.

Hence the outrage over the “poor door” at a planned luxury condo project that Extell will build on Manhattan’s Upper West Side: market-rate buyers will use one entrance, while tenants in the project’s affordable housing component will use another. Affordable apartments will also be on low floors and, unlike many of the market-rate units, they won’t face the Hudson River.

Getting mad about the “poor door” is absurd. The only real outrage is that Extell had to build affordable units at all.

New York’s housing advocates are right about one very important thing: upzonings are a windfall for landowners and the city should be asking for something in exchange for allowing more development. But what it should be asking for isn’t luxury apartments with river views to give out by lottery. It should be asking for cash.

Now, the reason for IZ isn’t solely about affordable housing, but about preserving and providing for mixed-income communities and for permanently affordable housing. All worthy goals, but the can come with a great deal of procedural headaches.
