Keys to Walkability

By Dom Nozzi

December 11, 2006

How do we make a place exceptionally walkable?

PROXIMITY is crucial as a measure – perhaps reducing all other measures to insignificance by comparison. In nearly all of America, unfortunately, our car-centric history has dispersed destinations to a point where it will be nearly impossible to retrofit walkability into American cities. Tragically, it will require decades or generations before we will see sufficient infill and densification in our communities for any semblance of area-wide walkability to be established.

In addition to lack of proximity, another enormous problem we face in striving to encourage more utilitarian walking (and bicycling and transit use) is that America is drowning in an over-abundance of FREE PARKING. When we know that plenty of free parking awaits us nearly everywhere we need to go, we are essentially being begged to drive a car, and we end up seeing many drive even when their destination is only a short distance away (and even though there may be wide sidewalks and vibrant, pulled-up-to-the-street buildings).

As an aside, the fact that free and abundant parking is so strongly demanded and is such a powerful way to manipulate travel behavior is curious, since for most Americans, there is little that is more anathema than deliberate behavior modification.

It is therefore essential that we work to restrict the availability of free and ample parking. Some strategies: unbundling the price of parking from housing, parking maximums instead of minimums for new construction, market-priced parking, locating the parking on the side or rear of new buildings, etc.

I just returned from a two-week trip in southern Italy and Sicily. It was magnificent, Catania Italy walkablecharming, romantic, delicious, boisterous, and invigorating. We visited some of the world’s most walkable cities, and enjoyed the experience of walking in places filled with pedestrians (mostly local, as we were there off-season). We were immersed in a walking culture.

Guess what? Most all of the places we walked had no sidewalk at all (or had “sidewalks” only a meter or so wide). “Pedestrian Level of Service” (called “PLOS”) is an effort to quantify the quality of the walking environment. Is the PLOS high or low in these Italian cities?

I believe so many walk in these wonderful Italian cities because of proximity, the difficulty in finding parking, and the expense of owning and driving a car. Very little (or none) of it is due to wide sidewalks or pleasant landscaping, unlike what many in America seem to think.

I believe that to promote walkability, many Americans call for the installation of wide sidewalks because truly effective strategies (proximity and restrained/priced parking) are 141104-harding2too costly, too painful, too long-term, or not seen as realistic in any way at all. So we build sidewalks (sometimes) because we can. It helps many of us pay lip service to providing walkability. And when no one ends up using the sidewalks, skeptics point to them as confirmation that Americans will never be pedestrians in any meaningful way.

In this interim, grim time for pedestrians, we need to encourage compact, human-scaled, parking-restrained, place-making projects that can serve as shining examples of what we need on a broader scale.

We have spent enormous sums of public and private dollars, and several decades, to do all we can to enable car travel. For most of America, there will be no overnight path to walkability.

Indeed, as James Howard Kunstler argues, much of America may not have a future.

Why Are American Cities Not Able to Encourage Large Numbers to Walk?

 

By Dom Nozzi

May 28, 2009

The conventional wisdom says that we can encourage large numbers of people to walk if we just provided a lot of well-designed sidewalks.

But after over 20 years, I’m still waiting for American cities to show this will happen. The city I worked for as a town planner had nearly 100 percent coverage of neighborhoods by sidewalks, but only a vanishingly small number of citizens walked – even though our population contained a large number of relatively healthy, young strip commercial sidewalkstudents.

Why are more not walking? Is there something we could do to sidewalks to make them more “enjoyable, comfortable, and safe”?

Could it maybe be that people prefer driving when all that free and abundant parking that awaits them everywhere, rather than walking 5 miles?

I’m still waiting for ONE example of a community in the US which has successfully employed the strategy of widespread sidewalk provision to encourage a lot of walking.

I know of none.

Even if there was a community which could afford the astronomical costs, sidewalks (and bike lanes and bike paths) are not likely to induce regular commuting or shopping trips by mom, kids and seniors (and healthy young people) when the distances are extreme, as they are in almost all of suburbia.

Fortunately for those of us who urge effective tactics, it doesn’t really matter if we have no elected officials who are willing to do what is necessary to effectively induce non-motorized travel (such as a big sales tax increase, or more compact development).

No matter how much most Americans love suburbia and car dependency, they will not be able to vote to escape the inevitable and substantial increase in gasoline prices, and other inevitably rising prices associated with car travel.

There will be a lot of pain, agony, wailing and gnashing of teeth when this happens — particularly in suburbia, where so many have thought that they were forever entitled to $2/gallon gas.

Once this inevitable increase sends gas over $10/gallon, Jim Kunstler and I (who discussed this yesterday at a cafe) are certain that there will be a miraculous “enlightenment.” Suddenly, even committed suburbanites will want transit, compact development, scarce and priced parking, mixed use, buildings at the sidewalk, and road diets. Such community features will become wildly popular (rather than there being vigorously opposed as they are today).

The problem, of course, is that if we’ve not installed quality transit, compact development, scarce and priced parking, mixed use, buildings at the sidewalk, and road diets in advance of the big rise in gas costs (because we are, as Jim Kunstler likes to say, wicked, fat, stupid, lazy, overfed clowns), there will be a lot of pain and violence.

Widening streets will not be possible in the future. We won’t have the money. And even today’s car cheerleaders and sprawl promoters will see that 8-lane roads don’t make sense when gas costs $15/gallon.

As for kids playing in the streets, I recommend reading Fighting Traffic (Norton). One hundred years ago, parents, teachers, and police officers insisted that kids had the right to freely play in the streets. Those days will return when gas prices skyrocket.

As a side note, even though NO ONE thought that university students in my Florida community would EVER ride the bus when I was a planner there in the 1980s, that city saw a HUGE numbers using the bus starting in the late 1990s.

Was it because we used the carrots of enjoyable, comfortable, and safe buses?

Nope.

It was because we used effective tactics that I also recommend for biking and walking: Parking at the university campus is scarce and priced (and a big pain in the ass).

I am fully and sadly aware that the effective tactics I recommend are extremely difficult, if not impossible to achieve in most of the US, politically. But opting for other more feasible tactics (bike lanes, bike parking, bike showers, sidewalks) doesn’t make them effective simply because we can achieve them more easily.

Let’s be honest: Most American communities are doomed because we have spent several decades building communities that have no future because it is nearly impossible to retrofit them for transportation choice and other forms of sustainability.

I’m building a bomb shelter for the coming empire collapse…

Why I Became a Town Planner

 

By Dom Nozzi

May 28, 2005

Several years ago, while I was an undergraduate in environmental science, I came across a study that sought to determine if there were correlations between a person being an environmental activist (or living a low-impact lifestyle) and childhood experiences. A vast number of experiences were analyzed. One experience stood out head and shoulders above any other experience to explain why a person was a conservationist as an adult.

The person, as a child, enjoyed free, unrestricted access to unstructured play in natural areas (open spaces, woodlands, etc.).

That finding motivated me to enter the field of urban planning, as I realized that in such a profession, I could perhaps help a community design itself so that children would not be denied such a crucially important childhood experience.

In recent years, I have come to learn that even if such places remain in or near neighborhoods, our car-happy culture has made it increasingly impossible for children (or adults, for that matter) to walk or bicycle to such places. Roads have become treacherous death zones that isolate children from their desired locations (unless Mom is able to serve as a taxi driver). boy biking low speed street

I have therefore turned much of my interest to the design of communities that employs traditional, timeless, walkable, human-scaled principles. Mostly embodied in the techniques used in the new urbanist, place-making movement, I have become convinced that a walkable community is an essential lynchpin in creating a high quality of life for all people—and, importantly, provides children with access to unstructured play.

Fleeing from the Public Realm

By Dom Nozzi

Over the past several decades, Americans have increasingly cocooned themselves. As the fear of crime (and “strangers”) remains high, many spend more time than their parents and grandparents inside the private realm of their homes – homes that are increasingly becoming walled, fortified, burglar-alarmed fortresses on cul-de-sacs. Many have fled from the more communal, compact town center neighborhoods to dispersed, low-density sprawl neighborhoods. Some of us live within “gated” communities where a guard grants permission to visitors wanting to enter the “compound” of a walled-in neighborhood.Phoenix-Gated-Community

The move toward the private realm is a form of escape from public life. I believe the desire to escape is driven, at least in part, by the increasing misery, barren-ness, and danger associated with the relatively awful American public realm. As the public realm becomes increasingly dreadful in these ways, we have almost completely lost any sense of community, or the common good, or any form of civic pride. Of course, some might point to the jingoistic pride that is often exhibited (flag waving, “USA!!”chants, etc.), but I think that most of that sort of national “pride” is largely associated with the fact that our cheap energy economy is able to deliver a cornucopia of consumer goods (and political freedom, which has lost its meaning because there is no one worthy of our vote) to even those in the lower classes.

2012-garage-full-of-yard-saleIndeed, many, many people, in my opinion, mistake the ability to buy a bunch of consumer goods with political liberty, freedom, and quality of life. The end of cheap energy, I believe, will lead to big increases in political turmoil fueled by economic resentment and economic misery. Scarcity and the high costs associated with that will, I hope, compel us to be more interested in and drawn to community and the public realm, and less focused on an “all about me” attitude.

As a side note, I was horrified a number of years back to see a quote from a University of Florida student in the College Park neighborhood in Gainesville, Florida. The student was being cited by City Codes Enforcement for his unkempt, littered yard. He told the officer that he had a right to have his yard be a mess because of the political liberty that Americans enjoy.

WHAT??

In other words, a good many people apparently (and bizarrely) equate liberty with the right to litter or otherwise behave in an uncivil manner. “Screw others!”

In my travels in Europe, by stunning contrast, I am invariably completely astonished by the magnificent, ornamental, historic civic buildings, public squares, and shops that I see nearly everywhere I go. The public realm, unlike the downwardly spiraling and increasingly neglected place of misery that so many Americans are fleeing, consists — in the older parts of European cities — of places worth caring about.

In these charming, romantic, human-scaled sections of Europe, one finds it fantastically rewarding to walk the livable, human-scaled streets — many of which were bustling places filled with pedestrians and busy shops and outdoor cafes.

The vitality is contagious. And powerfully rewarding, because the human species is naturally sociable, yet as an American I so rarely can experience it in public – in American cities and suburbs. Nearly everyone on the European streets seem to be friendly and happy and sociable. It is so very exciting to me to see the enormous number of people walking and bicycling on very narrow, cozy streets. Traveling without a car is clearly and dramatically more humanizing for the Europeans.

In a car, even the most mild-mannered, friendly person is often compelled to get angry at “slow-pokes”, or to fume about pedestrians and other cars in the way, or how long it takes for the signal light to change. Blood pressure rises. Fellow citizens become enemies in a competition for road space. The ability to offer a friendly “hello” to your fellow citizen is lost inside a car, as is any real sense of SERENDIPITY, which is so important to a rewarding journey.

Inside a car, one usually feels as if he or she is always in a hurry.

Only as a pedestrian or bicyclist does one experience the unhurried pleasure of taking your time to smell the flowers and enjoy the morning sun. To stop to chat with an old friend you run into. To pop into a store because of something that caught your eye.

So the rich, rewarding experiences I so often joyously find in Europe are due to these human-scaled, slow-speed, pedestrian-oriented, activated streets I see there so regularly. Streets full of happy, sociable people, busy shops and cafes, and proud buildings lavishly ornamented.vibrancy stroget st

In America, most of what we experience is what Jim Kunstler calls an “auto slum.” Who wants to go for a walk in a place full of angry, high-speed motorists on 8-lane arterial roads, vast and empty asphalt parking lots?

The wretched, all-too-common experience of a strip corridor littered with auto repair shops and car dealerships, and buildings that are so far from the road that a person on the sidewalk would need a telescope to see into store windows? Assuming there even ARE windows, since growing numbers of buildings now turn their back to the street.

The natural, expected reaction for almost any sane person is to RUN FOR YOUR LIFE from such a place and safely cocoon yourself into your own little private realm, where you can endlessly, pathetically strive to be happy by buying flat-screen TVs, iPods, and luxurious furniture as a surrogate for living in a rewarding community. But how satisfying is it, in the end, to have a stupendous living room, when you don’t even know your neighbor? When all of your “friends” are simply characters in sit-coms you watch every night on TV? When your city is little more than a tangled, dangerous mess of stressed and hostile motorists, highways, parking lots, and fast food chains?

Our consumer economy thrives because it is simply not possible to buy things as a way to be happy, yet we feel compelled to buy, buy, buy in our endless, hopeless pursuit of happiness. There is, after all, no alternative, since we have no community or quality public realm to satisfy our gregarious human desires. Advertising constantly tells us that we will feel so much joy if we buy their product. But we learn that buying and owning the latest gadget is, ultimately, an empty, sterile way to live and enjoy life.

I’ve heard more than once that the Europeans are destined to a future quality of life that nearly everyone throughout the world will see as higher that the quality of life experienced in America. A recent book is titled “The European Dream” (an illuminating play on the “American Dream” we have grown up with).

I am convinced that this transition to looking at older Europe as the new dream is certain, because the European public realm is very high in quality (light years better than the miserable public realm in most all of America), and a quality public realm is the fountainhead to a high quality of life for the entire community. Quality of life is NOT found by buying the latest plasma TV set or SUV.

Ingredients for Walkability

By Dom Nozzi

Transportation is Destiny: Design for Happy People, Not Happy Cars

by Dom Nozzi

The following is a summary of a talk I was invited to give at a PLAN-Boulder County forum on Friday, January 24. As a town and transportation planner, I cautioned Boulder not to put too much emphasis on easing car traffic flows—particularly by such conventional methods as adding a second turn lane at intersections or requiring a developer to provide too much car parking. I described the ingredients of a healthy, vibrant city, summarized how a seemingly beneficial city objective of reducing traffic congestion can often undermine important Boulder objectives, and offered a number of strategies that would help Boulder both properly manage transportation and promote its long-range goals.

A great city is compact, human scaled, has a slow speed center, and promotes gatherings of citizens that catalyze “synergistic interaction” (brilliant ideas and innovations, as the sum becomes greater than its parts). Most importantly, a quality city does exceptionally well in promoting “exchanges” of goods, services, and ideas, which is the most important role of a city, and is best promoted by the interaction that occurs through compact community design.

About 100 years ago, automakers, home builders, and oil companies (“the Sprawl Lobby”) started realizing that they could make lots of money by creating what has since become a self-perpetuating vicious cycle in communities. If communities could be convinced to ease the flow of car traffic by building enormous highways and parking lots (and subsidizing car travel by having everyone—not just motorists—pay for such roads, parking, and gasoline), huge amounts of money could be made selling cars, homes and gasoline. The process eventually was feeding on itself in a growing, self-perpetuating way, because the highways, parking and subsidies were forcing and otherwise encouraging a growing number of Americans to buy more and more cars, use more and more gasoline, and buy sprawling homes that were further and further from the town center. Why? Because the subsidized highways and gasoline were powerfully promoting community dispersal, high speeds, isolation, and an insatiable demand for larger highways and parking lots. Each of these factors were toxic to a city, led to government and household financial difficulties, destroyed in-town quality of life (which added to the desire to live in sprawl locations), and made travel by transit, bicycle or walking increasingly difficult and unlikely (an added inducement to buy more cars).

The inevitable result of the Sprawl Lobby efforts has been that cities throughout America are dying from the “Gigantism” disease.

The “Gigantism” Disease

One of the most important problems we face is that cars consume enormous amounts of space. On average, a person in a parked car takes up about 17 times more space than a person in a chair. And when moving, a motorist can take up to 100 times as much space as a person in a chair. Cities are Untitledseverely diminished by this level of wasteful use of land by cars—particularly in town centers (where space is so dear), and especially in communities such as Boulder, where land is so expensive.

Overemphasis on car travel breeds and spreads the gigantism “infection,” and promotes ruinously higher travel speeds. What happens when we combine the gigantism and high speeds with the “travel time budget” (humans tend to have a budget of about 1.1 hours of round-trip commuting travel each day)?

People demand larger highways and parking lots. Gigantic highways, overpasses, and asphalt seas of parking are necessary to accommodate the space-hogging, high-speed needs of the growing number of cars. This process dramatically increases the “habitat” for cars, and because such places are so utterly inhospitable to people, substantially shrinks the habitat for people.

Because it is so dangerous, unpleasant, and infeasible to travel on these monster highways by bicycle, walking, or transit (what economists call “The Barrier Effect”), an endlessly growing army of motorists and sprawl residents is thereby created, which, of course, is a financial bonanza for the Sprawl Lobby.

It is surprising and disappointing that Boulder has, on numerous occasions, shown symptoms of the gigantism disease (surprising because citizens and city staff are relatively well-informed on transportation issues). A leading concern in Boulder is the many intersections that have been expanded by installing double left turn lanes. Installing a single left turn lane historically resulted in a fair improvement in traffic flow, but when a second left turn lane is installed, intersections typically suffer from severely diminished returns. There is only a tiny increase in traffic accommodated (and often, this increase is short-lived) and this small benefit is offset by a huge required increase in walk time for crosswalks that are now very lengthy to cross on foot (which necessitates a very long “walk” phase for the crosswalk). Indeed, some traffic engineers or elected officials are so intolerant of the time-consuming long walk phase that many double-left turn intersections actually PROHIBIT pedestrian crossings by law.

These monster double left turn intersections destroy human scale and sense of place. They create a place-less, car-only intersection where walking and bicycling (and, indirectly, transit) trips are so difficult and unpleasant that more trips in the community are now by car, and less by walking, bicycling and transit. And those newly-induced car trips, despite the conventional wisdom, actually INCREASE greenhouse gas emissions (due to the induced increase in car trips).

Double left turn lanes (like big parking lots and five- or seven-lane highways) disperse housing, jobs, and shops in the community, as the intersection—at least briefly—is able to accommodate more regional car trips. Because the intersection has become so inhospitable, placeless and lacking in human scale, the double left turn repels any residences, shops, or offices from being located anywhere near the intersection, and thereby effectively prevents the intersection from ever evolving into a more walkable, compact, village-like setting.

The following chart shows that, because of the enormous space consumption caused by higher-speed car travel, land consumption rate increases are far out-pacing growth in community populations. For example, from 1950 to 1990, the St. Louis population grew by 35 percent. chartYet land consumption in St. Louis grew by 354 percent during that same period.

Given all of this, a centerpiece objective of the Boulder Transportation Master Plan (no more than 20 percent of road mileage is allowed to be congested) may not only be counterproductive in achieving many Boulder objectives, but may actually result in Boulder joining hands with the Sprawl Lobby.

The congestion reduction objective has a number of unintended, undesirable consequences. The objective tells Boulder that the highly desirable tactic of “road diets” (where travel lanes are removed to create a safer, more human-scaled street that can now install bike lanes, on-street parking, and wider sidewalks) are actually undesirable because they can increase congestion. The objective provides justification for looking upon a wider road, a bigger intersection, or a bigger parking lot as desirable, despite the well-documented fact that such gigantic facilities promote sprawl, car emissions, financial difficulties, higher taxes, and lower quality of life, among other detriments.

The objective also tells us that smaller, more affordable infill housing is undesirable—again because such housing can increase congestion.

The Shocking Revolution

The growing awareness of the problems associated with easing car travel (via such things as a congestion reduction objective) is leading to a shocking revolution across the nation. Florida, for example, now realizes that if new development is only allowed if “adequate” road capacity is available for the new development (which is based on “concurrency” rules in Florida’s Growth Management law), the state is powerfully promoting sprawl. Why? Because the available road capacity tends to only be found in sprawl locations. In-town locations, where new development tends to be much more desirable, is strongly discouraged by this Florida concurrency rule because in-town locations tend to have no available road capacity (due to existing, more dense development in town).

As an aside, “concurrency” is a rule that says new development is not allowed if it will lower service level standards adopted by the community. For example, standards might state that there must be at least 10 acres of parkland provided for every 1,000 residents. While concurrency is clearly a good idea for such things as parks and water supply and schools, it is counterproductive for roads.

The shocking revolution in Florida, then, is that the state is now allowing local governments to create “exception areas” for road congestion. If the community can show that it is providing adequate bicycle, pedestrian and transit facilities, the state will grant the local government the ability to create road exceptions so that the road congestion avoidance strategy brought by Florida’s road concurrency rule does not significantly encourage new sprawl and discourage in-town, infill development.

Similarly, California is now acknowledging the unintended, undesirable effects of past efforts to ensure that roads are “free-flowing” for car traffic. “Free flowing” car traffic tends to be measured with “level of service” (LOS) measures. Road LOS is a measure of traffic delay. An intersection (or road) where a car must wait for, say, three cycles of a traffic signal to be able to proceed through the intersection might be given an LOS rating of “F.” An intersection where a car can proceed through an intersection without such delay is given an LOS rating of “A.”

California now realizes that too often, building wider highways or stopping new development as a way to maintain free-flowing car traffic (LOS “A”) is substantially counterproductive. The state now realizes that maintaining or requiring easy, free-flowing car traffic increases greenhouse gas emissions (shocking, since the opposite was formerly believed), increases the number of car trips, and decreases the number of walking, bicycling and transit trips. Free-flowing road “LOS” measures are therefore now being phased out in California.

The “congestion reduction” objective in Boulder’s transportation plan is, in effect, a “happy cars” objective that equates easy car travel with quality of life and sustainability. One important reason why this “happy cars” objective is counterproductive is that cars and people have dramatically different needs and desires—needs and desires that are significantly and frequently in conflict. For example, designing shopping for happy people means the creation of smaller, human-scaled settings where buildings rather than parking lots are placed next to the streetside sidewalk. Where streets are only two or three lanes wide and designed for slow-speed car travel. Where street trees hug the street.

Designing shopping for happy cars, by strong contrast, requires huge car-scaled dimensions. Giant asphalt parking lots are placed between the now giant retail store and the street, which invites easy car parking (but loss of human scale, sense of place, and ease of walking). Streets become what Chuck Marohn calls “stroads”:  5- or 7-lane monster roads intended for dangerous, inhospitable high-speeds. They are roads where streets belong, but their big size and high speeds make them more like roads. Street trees are frequently incompatible with happy cars, as engineers fear cars might crash into them.

Again, this comparison shows that by promoting “happy cars,” Boulder’s congestion reduction objective is undermining its important quality of life and city-building objectives.

Indeed, Enrique Penalosa, the former mayor of Bogota, Columbia, once stated that “a city can be friendly to people or it can be friendly to cars, but it can’t be both.” Boulder’s congestion reduction objective is in conflict with this essential truth.

Fortunately, congestion regulates itself if we let it. Congestion will persuade some to drive at non-rush hour times, or take less congested routes, or travel by walking, bicycling, or transit. Congestion therefore does not inexorably lead to gridlock if we don’t widen a road or intersection, because some car trips (the “lower-value” trips) do not occur. Many of those discouraged trips are foregone because of the “time tax” imposed by the congestion.

But widening a road (or, in Boulder’s case, adding a second left-turn lane) short-circuits this self-regulation. A widened road or a double-left turn lane intersection induces new car trips because the road/intersection is now (briefly) less congested. The lower congestion encourages formerly discouraged car trips to now use the route during rush hour. Car trips that used different routes to avoid the congestion now converge back on the less congested route. And some get back in their cars after a period of walking, bicycling or using transit.

The process is very much like the infamous Soviet bread lines. The Soviets wanted to reduce the extremely long lines of people waiting for free bread. Their counterproductive “solution” was to make more free bread. But more free bread just induced more people to line up for bread. Likewise, the conventional American solution to traffic congestion is to make more free space for cars (widening the road or adding a second turn lane). The result is the same, as the bigger roads and intersections inevitably induce more car trips on those routes. The efficient and effective solution, as any first-year economics student will point out, is to NOT make more free bread or wider, free-to-use roads or second turn lanes. The solution is to price the bread and the car routes so that they are used more efficiently (and not wastefully by low-value bread consumers or car travelers). Or, to let a moderate level of congestion discourage low-value rush hour trips.

Given all of this, widening a road or adding a second left-turn lane to solve congestion is like loosening one’s belt to solve obesity. Similarly, despite conventional wisdom, car traffic does not behave like water flowing through a pipe (i.e., flowing easier if the pipe is expanded in size). Car traffic, instead, behaves like a gas.

Boulder’s Overriding Objectives

Boulder (and PLAN-Boulder County) has outlined key community objectives.

1. One is higher quality of life and more happiness. But counterproductively, happy cars lower quality of life due to clashing values and needs.

2. Another objective is for a more compact, walkable, vibrant city. Unfortunately, over-emphasizing cars means more sprawl.

3. An objective that is much talked about in the area is more affordability. By inducing more car dependence via easier car travel, the congestion reduction objective undermines the affordability objective by making Boulder less affordable (more on that later).

4. Given the growing concern for global warming, Boulder is placing more emphasis on reducing greenhouse gas emissions. Easing traffic congestion, however, induces new car traffic, which increases car emissions.

5. Boulder and PLAN-Boulder County seek more travel (and lifestyle) choices. But the congestion reduction objective in Boulder’s plan is again undercutting other objectives because it leads to bigger car infrastructure (bigger roads and intersections), thereby reducing travel and lifestyle choices.

As shown above, then, Boulder’s congestion reduction objective undermines each of these five essential community objectives.

Oops.

Conventional methods of reducing congestion include wider roads, bigger parking lots, one-way streets, and huge intersections. These tactics are a “win-lose” proposition. While they can reduce congestion (briefly), they also cause a loss of human scale and charm; a loss of social gathering; sprawling dispersal; more car dependence and less bicycling, walking, transit; higher taxes; economic woes (for government, shops and households); a decline in public health; and more air pollution.

By striking contrast, other less commonly used but much more beneficial transportation tactics are “win-win” propositions. Some of these tactics include road diets, designing streets for slower speeds, and designing for travel and lifestyle choices. They can result in:

  • More parking spaces
  • More civic pride (induced by human scale)
  • More social gathering
  • A more compact and vibrant community
  • Less car dependence and more bicycling, walking, and transit
  • Lower taxes
  • Economic health (for both government and households)
  • Improvement in public health
  • Less air pollution

If we can’t get rid of congestion, what CAN we do? We can create alternatives so that those who are unwilling to tolerate the congestion can find ways to avoid it. Congestion can be better avoided if we create more housing near jobs, shops, and culture. Doing this allows more people to have better, more feasible ways to travel without a car. We can also create more travel routes, so that the congested routes are not the only routes to our destinations. Some of us can be given more flexible work schedules to shift our work hours away from rush hour. And some of us can be given increased opportunities to telecommute (work from home).

How Can We Design Transportation to Achieve a Better Destiny?

An important way to start Boulder on a better destiny for the city is to revisit the “No more than 20 percent congested road miles” objective in the Boulder transportation master plan. Some possibilities: adopt a “level of service standard” not for cars, but for bicycle, walking and transit travel; “Level of service” standards for cars is becoming outdated because it is being increasingly seen as counterproductive, as described earlier. Other alternatives to the “congestion” objective is to have a target of controlling or reducing vehicle miles traveled (VMT) community-wide; or set a goal of minimizing trip generation by individual new developments in the city.

Another option is to keep the congestion objective, but create “exception” areas where the congestion rule does not apply. Those exception areas would be places where Boulder seeks to encourage new development.

Boulder needs to ensure that the community land development and transportation design tactics are appropriately calibrated within each “transect zone” of the community. (The “transect” principle identifies a transition from urban to rural, whereby the town center is more compact, formal, low-speed, and walkable; the suburbs are more dispersed, informal, higher-speed, and drivable; and the rural areas most remote from the town center are more intended for a farming and conservation lifestyle. Development regulations and transportation designs are calibrated so that the differing lifestyle and travel objectives of each zone are best achieved.) However, the difficulty with the transect principle in places like Boulder is that the demand for compact, walkable lifestyles and travel choices is much higher than the supply of such places in Boulder. There is, in other words, a large mismatch. By contrast, the supply of suburban, drivable areas is quite high. To correct this imbalance, Boulder should strive to create a larger supply of compact, walkable places similar to Pearl Street Mall, the Boulder town center, and even the CU campus. Opportunities now being discussed are the creation of new, compact villages and town centers at places such as street intersections outside of the Boulder town center.

As an aside, the community transect concept informs us that in the town center, “more is better.” That is, the lifestyle being sought in the community center is one where more shops, more offices, and more housing enhances the lifestyle, as this more proximate, mixed, compact layout of land uses provides the thriving, sociable, convenient, vibrant, 24-hour ambience that many seeking the walkable lifestyle want more of.

By contrast, in the more drivable suburbs, “more is less.” That is, the drivable lifestyle is enhanced in quality when there is less density, less development, more dispersal, and more isolation of houses from shops and offices. The ambience generally desired is more quiet and private.

While town center housing is increasingly expensive compared to the suburbs—particularly in cities such as Boulder—such in-town housing provides significant cost savings for transportation. Because such a housing location provides so many travel choices beyond car travel, many households find they can own two cars instead of three or one car instead of two. And each car that a household can “shed” due to the richness of travel choices provides more household income that can be directed to housing expenses such as a mortgage or rent. Today, the average car costs about $9,000 per year to own and operate. In places that are compact and walkable, that $9,000 (or $18,000) per year can be devoted to housing, thereby improving affordability.

In addition to providing for the full range of housing and travel choices, Boulder can better achieve its objectives through road diets, where travel lanes are removed and more space is provided for such things as bike lanes or sidewalks or transit. Road diets are increasingly used throughout the nation—particularly converting roads from four lanes to three. Up to about 25,000 vehicle trips per day on the road, a road that is “dieted” to, say, three lanes carries about as much traffic as a four-lane road. This is mostly due to the fact that the inside lanes of a four-laner frequently must act as turn lanes for cars waiting to make a left turn. Four-lane roads are less desirable than three-lane streets because they induce more car trips and reduce bicycle, walking and transit trips. Compared to three-lane streets, four-lane roads result in more speeding traffic. As a result, four-laners create a higher crash rate than three-lane streets. Finally, because the road-diet (3)three-lane street is more human-scaled, pleasant, lower-speed, and thereby place-making, a three-lane street is better than a four-lane street for shops. The three-lane street becomes a place to drive TO, rather than drive THROUGH (as is the case with a four-lane street).

If Boulder seeks to be transformative with transportation—that is, if the city seeks to significantly shift car trips to walking, bicycling and transit trips (rather than the relatively modest shifts the city has achieved in the past)—it must recognize that it is NOT about providing more bike paths, sidewalks, or transit service. It is about taking away road and parking space from cars, and taking away subsidies for car travel.

Another transportation tactic Boulder should pursue to achieve a better destiny is to unbundle the price of parking from the price of housing. People who own less (or no) cars should have the choice of opting for more affordable housing—housing that does not include the very expensive cost of provided parking. Currently, little or no housing in Boulder provides the buyer or renter the option of having lower cost housing payments by choosing not to pay for parking. Particularly in a place like Boulder, where land values are so high, even housing intended to be relatively affordable is more costly than it needs to be because the land needed for parking adds a large cost to the housing price. Indeed, by requiring the home buyer or renter to pay more for parking, bundled parking price creates a financial incentive for owning and using more cars than would have otherwise been the case.

Boulder should also strive to provide parking more efficiently by pricing more parking. Too much parking in Boulder is both abundant and free. Less parking would be needed in the city (which would make the city more affordable, by the way) if it were efficiently priced. Donald Shoup recommends, for example, that parking meters be priced to ensure that in general, 2 or 3 parking spaces will be vacant on each block.

Efficient parking methods that could be used more often in Boulder include allowing shops and offices and churches to share their parking. This opportunity is particularly available when different land uses (say churches and shops) don’t share the same hours of operation. Again, sharing more parking reduces the amount of parking needed in the city, which makes the city more compact, walkable, enjoyable and active.

Like shared parking, leased parking allows for a reduction in parking needed. If Boulder, for example, owns a parking garage, some of the spaces can be leased to nearby offices, shops, or housing so that those particular land uses do not need to create their own parking.

Finally, a relatively easy and quick way for Boulder to beneficially reform and make more efficient its parking is to revise its parking regulations so that “minimum parking” is converted to “MAXIMUM parking.” Minimum parking rules, required throughout Boulder, are the conventional and increasingly outmoded way to regulate parking. They tell the developer that at least “X” amount of parking spaces must be provided for every “Y” square feet of building. This rule almost always requires the developer to provide excessive, very expensive parking, in large part because it is based on “worst case scenario” parking “needs.” That is, sufficient parking must be provided so that there will be enough on the busiest single day of the year (often the weekend after Thanksgiving). Such a provision means that for the other 364 days of the year, a large number of parking spaces sit empty, a very costly proposition.

In contrast, maximum parking rules tell the developer that there is an upper limit to the number of spaces that can be provided. This works much better for the community and the business because the business is better able to choose how much parking it needs and can finance. Since financial institutions that provide financing for new developments typically require the developer to provide the conventional (read: excessive) amounts of parking as a condition for obtaining a development loan, the big danger for communities in nearly all cases is that TOO MUCH parking will be provided rather than too little. The result of setting “maximum” instead of “minimum” parking rules is that excessive, worst case scenario parking developments become much more rare.

The reform of parking is easy: simply convert the existing minimum parking specifications to maximum parking standards (“at least 3 spaces per 1,000 square feet” becomes “no more than 3 spaces per 1,000 square feet). An incremental approach to this conversion is to apply maximum parking rules in those places that are already rich in travel choices, such as the Boulder town center.

Again, what will Boulder’s destiny be? As the preceding discussion sought to demonstrate, much of that destiny will be shaped by transportation decisions.

Will destiny be shaped by striving for happy people and happy places for people? Or will it be shaped by opting for the conventional, downwardly-spiraling effort of seeking easy car travel (and thereby unpleasant places where only a car can be happy – such as huge highways or parking lots)?

Will Boulder, in other words, retain or otherwise promote place-less conventional shopping centers full of deadening parking, car-only travel, lack of human interaction, and isolation? Or will the city move away from car-happy objectives such as the congestion reduction policy, and instead move toward a people-friendly future rich in sociability, pride in community, travel choices, sustainability, place-making and human scale?

An example of these contrasting destinies is Pearl Street. West Pearl features the charm and human scale we built historically. West Pearl Street exemplifies a lovable, walkable, calm, safe and inviting ambience where car speeds are slower, the street is more narrow, and the shops—by being pulled up to the streetside sidewalk—help form a comfortable sense of enclosure that activates the street and feels comfortable to walk. The shops tend to be smaller—more neighborhood-scaled.

East Pearl Street near 28th Street is starkly different. There, the street is a “stroad,” because it is an overly wide road that should be a more narrow, lower-speed street. Shops are pulled back long distances from the street. The street here is fronted not by interesting shop fronts but enormous seas of asphalt parking. The layout is car-scaled. The setting is hostile, unpleasant, unsafe, stressful and uninviting. The shops tend to be “Big Box” retail, and serve a regional “consumershed.” There is “no there there.”

East Pearl Street was built more recently by professional planners and engineers who have advanced degrees that far exceed the professionalism and education of those who designed the more lovable West Pearl Street. Where has the charm gone? Why have our streets become less pleasant in more recent years (by better trained and better educated designers, I might add)? Is it perhaps related to our more expensive and sophisticated efforts to ease car traffic and reduce congestion?

There is an inverse relationship between congestion and such measures as vehicle miles traveled and gas consumption. At the community level—despite the conventional wisdom—as congestion increases, vehicle miles traveled, gas consumption, air emissions DECREASE. And as conventional efforts to reduce congestion intensify, quality of life and sustainability also decrease.

Again, is Boulder aligning itself with the Sprawl Lobby by maintaining an objective of easing traffic flow – by striving to reduce congestion?

 

On Controlling Size

David Mohney reminds us that the first task of the urban designer is to control size. This not only pertains to the essential need to keep streets, building setbacks, and community dispersal modest in size. It also pertains to the highly important need to insist on controlling the size of service and delivery trucks. Over-sized trucks in Boulder lead the city down a ruinous path, as street and intersection dimensions are typically driven by the “design vehicle.” When trucks are relatively large, excessive truck size becomes the “design vehicle” which ends up driving the dimensions of city streets. A healthy city should be designed for human scale and safety, not for the needs of huge trucks. Indeed, because motor vehicles consume so much space, a sign of a healthy, well-designed community is that drivers of vehicles should feel inconvenienced. If driving vehicles feels comfortable, it is a signal that we have over-designed streets and allocated such excessive spaces that we have lost human scale and safety.

A proposal for human-scaled streets: in Boulder’s town center, no street should be larger than three lanes in size. Outside the town center, no street should be larger than five lanes in size. Anything more exceeds the human scaling needed for a pleasant, safe, sustainable community.

It is time to return to the timeless tradition of designing to make people happy, not cars. Boulder needs to start by revisiting its congestion reduction objective, putting a number of its roads on a “road diet,” and taking steps to make the provision of parking more efficient and conducive to a healthy city.
