Want to unlock investment? Give transit its own lane

Transit-oriented development concept for BRT corridor, Chapel Hill, NC. Dover, Kohl & Partners & AECOM, 2018.

As planners we tend to toss the around the relatively novel term “transit-oriented development.” There are clear advantages to having more souls around within walking distance of the public transit stop and local-serving commerce, all brought together in a compact, mixed-use, walkable package of architecture, street design, and public spaces. To get all that to happen, your city has to plan for it.

Sometimes there’s a debate about which comes first, the transit improvements or the transit-supportive growth. (“Transit-ready” and “transit-worthy” development come up, among the terms we rely on to explain why some corridors could be made more competitive in the hunt for infrastructure dollars, if they grow pre-established, ridership-inducing jobs and housing and other destinations).

But stop to think about this: Before the sprawl experiment— before American cities started orienting everything around single-occupant car trips— virtually all urban development was transit-oriented development. Back then we called it by much friendlier names, like “towns” and “neighborhoods” (so, given the choice, I still do). The heart of any given community coalesced around its stagecoach stop, its ferry landing, its train station, or its streetcar stop, in a natural process borne from convenience and value creation. It’s a proven, repeatable formula.

We can do the same thing today around modern investments in high-quality public transportation, including relatively economical bus rapid transit (BRT) corridors. The real estate development that underpins your town’s tax base depends on predictability; uncertainty is the enemy of investment. A firm upfront commitment to high-quality transit that dependably attracts riders will reduce the risk to investors. What will make riders choose transit over driving everywhere? Frequent, low-cost, reliable service? Yes. A visit-worthy neighborhood that’s easy to move around in on foot, once you’ve left the vehicle? Yes, and there are myriad other variables. But if we are going to do this with rubber-tire vehicles that share the streets with All Those Cars, one of the best things we can do is give the transit vehicles their own lane. The incentive to ride transit goes way up if your bus isn’t stuck in the same traffic you’d be in if you drove. The message with bus-only lanes is clear: If you don’t like sitting in congestion, get out of your car and ride the BRT.

Traumatized by the drop in ridership during the COVID-19 crisis, transit systems remain essential and will need every advantage to get back on their feet. Once vaccines allow for building up transit systems again, we will need to work fast to stabilize and grow them. We ought to feed them by growing neighborhoods that work, compete, and thrive in synergy with transit. It’s one reason that the land use policies and regulations that support compact, complete, connected communities are now more crucial than ever. —Victor

Progress, and a Pause to Rethink, in ATL's "Pittsburgh" Neighborhood

Rockwell Street: Incremental development is the medium; investments in people, the public realm, and regulatory reform are the catalysts.

Much can be accomplished when people pull together, and philanthropy can play a pivotal role in this aspect of community revitalization. The Annie E. Casey Foundation has just published an extensive summary of the housing progress made in Atlanta’s Pittsburgh neighborhood since our Preservation of Pittsburgh plan, funded by the Foundation and devised with deep public engagement, was created in 2012.

Once it was home to so many industrial jobs— and so much rust and pollution— that it reminded people of smoky northern cities, so they took to calling this part of Atlanta “Pittsburgh.” Neighborhoods like this one are revitalized step by step by many people; planning allows the public and private effort to be coordinated in a great neighborhood building enterprise with some idea of what the whole is meant to become as it evolves. At the urging of a spinoff nonprofit from the Foundation, the Dover-Kohl design team helped establish community consensus and restore expectations, through hands-on design with citizens. Hopefully that shared vision laid the groundwork for the future public support necessary for both preservation and redevelopment.

Balance, above all, is the theme in that plan; the many authors of the Preservation of Pittsburgh plan struggled to find equilibrium between equally important goals of historic preservation and a spirit of newness. The “citizen planner” team insisted that the plan include basics upfront like cleaning up vacant lots, preserving affordability, and improving safety while working toward the desired urban image for the heart of the community. The group effort defined Basic First Principles for preservation, revitalization and development without displacement. Today, as new housing is being created and a new neighborhood comeback is underway, those preservation and anti-displacement goals are certainly being tested, and it remains to be seen whether public policy will keep up, now that Pittsburgh is getting noticed. Philanthropy and non-profit organizations will continue to be central to this. Here’s a new story about nonprofits coming back to a reconstruction of one of the neighborhood’s most historic, and visually symbolic, structures.

Annie E. Casey Foundation report suggests Pittsburgh plan’s anti-displacement ideas will be sorely tested

Gradual change over time is the natural means of urban progress. Incremental development is the medium; investment in people, the public realm, and regulatory reform are the catalysts. As confidence returns to a street or neighborhood, each increment of progress should lay the groundwork for the next.

In our Pittsburgh work, we created a pair of “before and after” sequences that illustrate the idea of stepwise change over time. One (above) shows Rockwell Street evolving to include first community gardens, then infrastructure upgrades, then, eventually, new housing.

The second sequence, below, shows gradual transformation of McDaniel Street in the heart of the community. This one bears a pause to re-look, and rethink, in light of the Black Lives Matter movement and concerns over the role of police, because the sequence starts with the appearance of a police car and pop-up installation of a police kiosk. Here’s the backstory: When that watercolor was painted, desperation was high. That “police presence” image came from requests from citizens in the neighborhood; there was yet another shooting on the streets in Pittsburgh during the design charrette week, just steps from the design studio. Some of the neighbors felt like the City and public safety officers had just given up on them. Through today’s lens, though, that image of the overwatch kiosk might conjure fears of authoritarianism, and the anonymous squad car was a poor choice on my part; I wish we’d at least illustrated a cop interacting with neighbors during his/her walking beat, applying community policing principles, instead of that patrol car. I hope that in the years since, all our views about policing and over-policing have become more nuanced and alarmed. In the end, the City of Atlanta never did implement the kiosk idea.  —Victor

Pass the Great American Outdoors Act

OPEN MIC, published in The Miami Herald, July 16, 2020

In late June, the U.S. Senate approved the Great American Outdoors Act by a vote of 73-25, providing permanent funding for the Land and Water Conservation Fund (LWCF). Now the U.S. House of Representatives is scheduled to take up parallel legislation on July 22. Join the call to action and send your Congressional representative a note urging a Yes vote.

This legislation is important and needs your support. The LWCF, signed into law in 1965, has funded over 42,000 park and outdoor recreation projects nationally. Funded by oil and gas revenues — not taxpayers — the LWCF was originally designated for parks and outdoor recreation. And yet, over the years, Congress shortchanged the parks, failing to release billions of dollars that should have gone to parks.

This new legislation fixes that problem by making LWCF funding permanent.  As board members of the National Recreation and Parks Association, we see ample evidence of the significant contributions parks make to communities. A strong park system with ample green space and diverse programs supports a healthy, vital and resilient city. We also see that not all parks are equal, and neither is access to parks. We need to fix this.

If we didn’t realize it earlier, the pandemic has surely shown us the importance of parks in our lives. Providing green space, fresh air and sunlight, the parks and the parks professionals who keep our parks going demonstrate the essential role of parks in bringing our communities and families together, helping our people get and stay healthy, enhancing the lifestyle that enables our businesses and institutions recruit and retain talent, and serving as the memorable and profound landmarks of our civic identity.

We need the House of Representatives to act. We hope that you will contact your representatives in Congress and urge them to quickly pass the Great American Outdoors Act to ensure a greener and healthier Miami, South Florida, and USA for today and generations to come.

The Lifesaving, City-Shaping Power of Parks & Greenways (TPS Ep. 12)

, ,

The Dequindre Cut Greenway, Detroit

The design of a city begins with streets and squares and neighborhoods, but it also depends on its parks and open spaces, and the connections between them. Parks, greenways and blueways give form to the neighborhoods and bring nature into the city.

The Olmsted Vaux & Co. plan for Prospect Park, Brooklyn (1868)

Genesis of the modern planning profession

Kim Williams Trail, Downtown Missoula, MT

In many ways today’s practice of city planning was born with parks. Progressive reformers, concerned with public health in the smoky industrial cities, turned to landscape architects to create ample, green, open-to-the-sky spaces where people could relax amid nature, and the air and water could be cleansed. Frederick Law Olmsted’s idea for the Emerald Necklace of interconnected parks and green corridors in Boston was a public health idea, and a water-cleanup idea, not just a leisure idea. And the first American to identify himself as a professional city planner, John Nolen, was in fact a landscape architect by training, with a long career in parks planning already behind him as he began devising new towns and reshaping old ones.

These innovators realized the planning of neighborhoods and transportation corridors and the establishment of open spaces weren’t separate acts, to be dealt with in their own separate professional silos. And they understood that the green parts of a city aren’t just leftovers, to be ignored in between the built-up areas that receive all sorts of attention from architects, engineers and real estate developers. Instead, the natural and green parts should be subjects of design in themselves, allowing for restoration and maximizing community benefits and ecological values.

Starting a plan with the public spaces

Concept for a playground and neighborhood plaza from Plan El Paso (DK&P, 2012)

When we design a neighborhood, we begin with the green parts. We start with the tree-lined streets that link the small spaces where neighbors of all ages come together—including the youngest and oldest among us—and then work our way out to the playfields where children learn teamwork and grow fit, to the greenbelt or natural edges that shape the neighborhood, then to the trails or greenways that give respite in our busy daily lives.

Starting with the public space makes life the focus of placemaking, and makes real estate development the backdrop. This is the right order of things, because public spaces are where our memories of cities are formed.

Silos

Today’s parks and recreation programs are often operated in their own departments, separated from the day to day work of city planning departments, but their plans should be integrated, especially now, when park spaces hold the lifesaving, economy-saving solutions for urbanism in the era of climate change.

The economic power of parks

Parks do cost money in a city’s budget, but they add value straight back to the city’s revenue base and to the wealth of surrounding property owners. They save taxpayers money, too:

  • In the seminal study of its kind, Pennypack Park in Philadelphia was shown to have a positive impact on the value of surrounding taxable real estate of $2,600 per household. That’s $3.36 million per year—in 1974 dollars. (That’s about $17.5 million in 2020.)

  • Each year, Washington’s Rock Creek Park results in nearly $9 million in additional property taxes to cover crucial municipal needs in the District of Columbia.

  • Bryant Park in Manhattan offers a story of return on investment. Thanks to its renovation in the early 1990s, with its famous movable tables and chairs, Bryant Park now draws visits from 20,000 people each day. Rents in surrounding areas rose 56% between 1990 and 2002; in the same period, rents on properties directly overlooking the park rose an astonishing 170%.

  • Physical activities in Sacramento parks yield an estimated $20 million per year in medical-cost savings alone.

Getting there

A basic national goal has been set of having park space within ten minutes’ walk of every home. It’s a start. But it’s not just a matter of keeping the distance short—we also need good means of getting there. Nonmotorized transportation on bike-friendly, walk-friendly streets and multi-user trails are needed to connect our local parks to where we live and work and go to school. Once you arrive, a park should greet citizens with openness and a sense of welcome. In New York City, the Parks Department has spent the last several years removing the barricades and tall metal fences that once walled off the parks from the neighborhoods that surround them. Today we can see what NYC Parks Commissioner Mitchell Silver calls “parks without borders,” extending through these renewed connections to give everyone the option of a park life.

Even at the super-regional scale

Large-scale trail systems, like the East Coast Greenway, are gradually taking the interconnected web of park life to the next level, allowing for long nonmotorized commutes and bike tourism. The visions for these systems extend beyond the borders of municipalities and states, linking vast regions. It’s not a new idea. The proving ground for this super-regional approach was the beloved Appalachian Trail, first proposed by naturalist Benton MacKaye in 1921. MacKaye and his followers believed the key to human mental health and happiness was regular exposure to three “elemental landscapes,” essentially consisting of wilderness, working landscapes (like farms and working waterfronts), and cities. MacKaye saw park systems as offering a chance to offset the dehumanizing, de-naturalizing effects of mechanistic industrial work and brutal commerce—which he called “de-creation”—with what has since commonly come to be known as recreation:

“We need the big sweep of hills or sea as tonic for our jaded nerves - And so Mr. Benton MacKaye offers us a new theme in regional planning. It is not a plan for more efficient labor, but a plan of escape. He would as far as is practicable conserve the whole stretch of the Appalachian Mountains for recreation. Recreation in the biggest sense - the recreation of the spirit that is being crushed by the machinery of the modem industrial city - the spirit of fellowship and cooperation.”

Clarence Stein, 1921

Parco delle Rimembranze, Venice.

Green spaces and our physical and mental well-being

We know now that Olmsted, Nolen, Stein and MacKaye—among many others—were onto something big. Decades of scientific studies have linked regular access to green space for physical activity to chronic disease prevention, and the data show that just seeing green spaces speeds healing and boosts wellness. The NRPA Report from 2010 found that a thirty-minute walk among trees “lowers blood glucose levels far more than the same amount of time spent doing physical activity in other settings. Half-hour walks in forest result in larger drops in blood glucose than three hours of cycling.” The same report documents how twenty minutes of walking in a park improved concentration among kids with ADHD at least as much as two frequently prescribed ADHD drugs! Eight separate large-scale clinical studies found that regular visits to green spaces dramatically reduce stress (Stigsdotter, 2010 and Maller, 2008). Dutch researchers established that diagnoses of anxiety disorders are 44 percent higher in residential areas with less green space than in communities well-supplied with parks.

Listening to the land

The traditions in landscape architecture show us that parks, greenways and waterways take their best form when designers listen closely to the lay of the land, from the way the topography rolls, and folding in the natural courses of stormwater. Designed this way, the green weave supports not just human happiness but flood control, water quality, flyways for birds, pollinator corridors for winged insects, the food web, and adaptation to climate change and sea level rise.

The continuum of green: Newfield & its environs (Dover, Kohl & Partners, 2019)

Continuum of green

Pulling all this together, modern day parks-planning practitioners like David Barth describe a “continuum of green” that extends from the tiniest tot lot or pocket park, to the community garden, to the neighborhood square, to the recreational fields, to large scale parks, to restoration of wilderness and conservation areas, and beyond, all interconnected by greenways, tree-lined streets, broad green boulevards, and trails.

Parks, greenways, & blueways are spotlighted in Episode 12 of Town Planning Stuff Everyone Needs to Know. They are of primary importance and they affect everything. As Miami-Dade County’s parks director Maria Nardi likes to say, “Parks just might save the world.”

Street-Oriented Architecture (TPS Ep. 11)

, ,

Places where people like to be ALWAYS have street-oriented architecture. Have you had enough of the blank walls, garage doors, and parking lots along your si...

Perhaps the key distinguishing feature between vibrant urban places and the drab scenes Jim Kunstler once called “the geography of nowhere” is this:

Places where people like to be always have street-oriented architecture. The buildings are engaged with the street in some legible, designed way; there’s an indispensable building-to-street relationship that feels mutually reinforcing.

Anatomy of a main street storefront building

The street space, that “public room,” extends from building face to building face—so the way individual buildings are designed affects, and even creates, the experience we have in that space. Many traditional building types, lot layouts and architectural grammar evolved as they did for precisely this reason; they dependably create a good experience and present each building to its neighborhood in a respectable manner.

For example, porches within conversational distance of the sidewalk give houses a neighborly sociability, and provide an agreeable intermediate layer of space between the fully public street and the fully private interior. On intimate streets of rowhouses, stoops and dooryards leave no doubt about where the front façade of the building is.

The finished floors of most rowhouses in Old Town Alexandria are elevated above the sidewalk level for privacy.

In most cases, an elevated finished floor level on the first inhabited floor is useful because it gives the interiors of rowhouses and ground floor apartments an extra degree of privacy and dignity, offsetting the fact that they are so close to the public realm. If you’re walking by outside along the sidewalk, and the inhabitants have their curtains and shutters open, you might see their chandelier, but you won’t be staring at them sitting on the couch or seeing what they’re watching on television! You won’t feel like an intruder, and they won’t feel intruded upon. But here’s an important caveat: In our times, we also need to be sensitive when applying this traditional detail, by also making accommodations for accessibility and visibility. The traditional elevated finished floor makes access difficult for those in wheelchairs or with mobility impairments, so shared ramps, lifts, zero-step entrances into spaces below the piano nobile, slightly elevated alleys, and roll-in lobbies can all be employed.

Storefront buildings on King Street in Old Town Alexandria, Virginia. Small details of architectural grammar matter.

On commercial and mixed-use streets, well-designed storefronts are the key. Consider the anatomy of a traditional Main Street building. Again, the details of architecture intermediate between the public spaces and the private interiors. Awnings, arcades, colonnades, galleries and other appurtenances help us deal with the sun and rain, but they are also ways the architecture reaches out, engages with, and embraces the street space. On the most successful streets, there’s always a clear front door to each building, facing the street. Having frequent doors along the street reinforces the scene.

On main streets, mixed-use buildings should usually have an expression line just above the ground floor, such as a cornice or eyebrow, forming a base that separates the private upper floors from the public world of the commercial street scene below.

#WhatNotToDo

Now, compare all that to deep setbacks, parking lots in front, or to rows of garage doors and “snout houses,” and to blank walls. This soul-destroying pattern became commonplace in late 20th Century suburbia, yet it’s never been shown to work well at making a people-friendly place or street scene—not even once! By contrast, in traditional urbanism, pleasant streets and street-oriented architecture support each other, time and again. When the streets are hostile, we’ll invariably find buildings retreating from the street, recoiling, turning their backside toward the neighborhood.

The Power of Street Trees (TPS Ep. 10)

, , ,

Main Street, Greenville, South Carolina

There’s one detail that makes a huge difference in the public realm, and that’s the humble street tree.

Landscape architect Henry Arnold once said, “Fifty percent of urban design is, street trees.” On a tree-lined street, look up; the canopy forms the ceiling of our shared public room. Arnold wrote, “An urban street without street trees is like a building without a roof.”

Cours la Reine, Paris

Shaping space while lending beauty, order

The Ladd’s Addition neighborhood in Portland

Line street trees up, and something magic happens. A tree-lined street is a deliberate intervention, an ordering of the public space, a statement in the common human language of geometry. It never fails to make a place where more people want to be.

One tree, many benefits

However, street trees are not just about making the place more beautiful and ordering the space, but also:

Shade - They shade our walks and bike rides. Street trees can lower the urban heat island effect, by as much as three to seven degrees Fahrenheit.

Legare Street, Charleston, South Carolina

Value - They make the city more economically potent. Two identical houses in otherwise similar neighborhoods will command wildly different prices, if one is on a tree-lined street and the other isn’t.

Water - They hold stormwater and clean up pollution.

CO₂ - Critically, they sponge up carbon dioxide, a key greenhouse gas tied to global warming, and then they make oxygen—and we breathe that stuff!

Missoula, Montana

Lower Cooling Costs - In summer, trees shade the buildings and that lowers cooling costs, as much as 35%, and they cut glare, leaving a delightful pattern of dappled light on our streets.

Place, Brand - Flowering trees and autumn leaves put on spectacular annual shows, drawing us to these places.

Troy, New York. Kenneth García photo

Warmth - And in winter, in temperate climates, deciduous trees lose their leaves to let light in to warm the sidewalks and buildings.

Traffic Calming - They keep us safer, calming traffic.

Habits can be broken

For part of the twentieth century, the street tree tradition faded amid compacted city soil, bad habits and poor assumptions. Convinced— by examples with meager, incorrect planting pits—that urban trees will never thrive and they’ll die young, decision-makers began to question whether they were worth the effort and expense. Public works officials started trimming budgets with the old line, “We’ll add the trees in a later phase.” Some minimalists, seeing starkness as a virtue, pulled their architecture away from trees into wide-open displays. Some landscape architects and arborists began to oppose traditionally aligned trees with close spacing, arguing that this geometry was too formal and dissimilar from the way certain trees grow in the wilderness, and pointing out that the roots under each tree need substantial space. They were willing to forgo the benefits and visual effects of allowing the upper branches to intersect with those of the adjacent trees and having more continuous shade for pedestrians. During the same period, departments of transportation were focused on speeding up and accommodating more cars rather than slowing them down. So they started to see shade trees as a liability, insisting on flimsy “frangibles” instead of the sturdy oaks, maples and elms customary in times past.

Get the planting details correct

Generous planting areas on the avenues of Chicago, Illinois

The turnaround came as landscape architects like Arnold and others realized that, with the right planting details and species choices, urban trees can indeed thrive. Much depends on the preparation of the hole in which the tree will be planted. For example, for the Live Oaks common on streets here in Florida, one key is not only allowing for a larger area of loosened soil below ground for the primary roots seeking water, but also for a larger open area up top around the tree, where fine hair-like roots seek air and filtered sunlight. Our landscape architect Jay Hood specified an innovative planting system for Park Avenue in Winter Park that freed the tree trunks from tight wells with metal grates and allowed for walkable surfaces to float above the roots and loosened soil below. Those trees have defied all expectations and grown quite tall. Many people are surprised to learn they were planted so recently.

In the last couple decades, new techniques and products have emerged to improve the success of street trees in urban areas where space is tight and impervious surfaces predominate. So-called “structural soil” and underground suspension systems have become common. These allow the roots to spread within loosened soil without ramming into excessively compacted earth, yet they solve the problematic lifting of sidewalks.

On wide boulevards and leafy residential streets where trees can be planted in linear, continuous landscape strips, your crew can dig a long trench for the whole tree line rather than individual circular holes. After planting and backfilling (avoiding too much compacting), this produces a larger area of loosened soil for the roots to explore. Naturally this requires thinking ahead about the alignment of underground utilities, drainage, and other details. Bottom line: Consult a competent professional on the right way to plant your street trees.

Beautiful exceptions: Cour du Commerce Saint-André in Paris, and Calle Malasia, in Buenos Aires’ Belgrano neighborhood

Exceptions to the rule

For all the reasons we’ve reviewed, on most of our streets and in most of our communities, we’re better off with lines of street trees, especially in temperate, moderately humid climates. But there are exceptions to this rule. For example, extraordinarily arid places where water is scarce or costly call for other solutions to supplying shade and visual interest, such as narrow streets with buildings brought closer together and cantilevered architectural elements that encroach beyond the building envelope. Fewer trees can also be best for far-north climates where letting more sun in during the many shortened days outranks having shade on the rare warm day. Even in a sunny place where trees grow easily, we might still opt for a unique, skinny, tree-less street here and there in a neighborhood plan, to diversify the addresses and experiences on offer. There are also many kinds of commercial streets and passages, and not all require shade trees; some replace the canopy effect with suspended fabrics, galleries, or portals; others establish the visual interest with creative signs and artwork or palms or flowers instead of shade trees. With or without trees, we also take care to keep clear lines of sight to signage and storefronts on mercantile streets. In Street Design, we also wrote about the usefulness of what Raymond Unwin called the “lean-in” tree, planted in the adjacent garden instead of within the right-of-way.

As with every other detail in city design, context is crucial.

Standard equipment for great cities

When they’re right, they’re right, which is most of the time—so street trees are not just a decorative frill, something to be cut when the budget’s tight. They’re mission-critical equipment in making good, resilient cities and towns, and that’s why they’re number ten on my list of Town Planning Stuff Everyone Needs to Know.

Walkable Street Design: 5 Must-Haves (TPS Ep. 9)

, ,

People first

The latest episode of Town Planning Stuff Everyone Needs to Know is about street design. That’s because all successful towns are walkable, and design is the key to that. Design for pedestrian safety and happiness simply can’t be an afterthought, merely considered—if at all—only after all the automobile-related decisions are already made.

Bologna, Winter Park, and Rome

“Walkability,” in this context, is really a stand-in word for pedestrian friendliness and bike-friendliness and accessibility for all, including folks in wheelchairs or with other mobility challenges. Walkable streets don’t just technically allow for people outside cars, they’re welcoming, attractive, less stressful, and livable. A perfunctory sidewalk right next to whizzing cars or a faded painted stripe indicating a bike lane are definitely not enough.

Main Street, Galena IL

Main Street and its environs, Galena IL

Design is indispensable

We should start with walkability as an essential baseline, and then work our way out to all the other considerations like truck access, parking and the like. That’s because the best streets are more than mere transportation corridors—and more than just functionally walkable rights-of-way. When their designs are artful, these streets become unique addresses, places where people especially want to be. Streets need what Steve Mouzon calls “walk appeal” in order to inspire citizens, ignite commerce, and attract real estate investment. Eminent urbanist Allan Jacobs, who inspired generations with his book Great Streets, pointed out that some thoroughfares can even mature into the ranks of what he termed the “great world streets,” distinctive landmarks that endure and set their cities apart from their peers.

Good or great, streets come in many sizes and designs. Immense variety is possible. Upcoming episodes of Town Planning Stuff describe the eleven fundamental street types, and as we’ll show, there are many, many variations on each.

Five basic features

While there are many options in street design, we find there are a few must-have features always present in people-first streets. These features dependably draw people—and these are features your elected officials can demand in your town. That demand usually has to come from both the grassroots and from the top. As former longtime Charleston mayor Joseph Riley has said, “The mayor is the chief urban designer of the city.”

Rue St. Jean, Quebec: Shaped, comfortable, connected, safe, memorable

First, good streets are shaped. The street space is given a designed form, like an outdoor public room, with the roadway and sidewalk its floor, the buildings its walls, and, sometimes, its ceiling formed by the tree canopy.

Second, they’re comfortable. In most climates that means shaded in the summer. Street trees, and architectural elements like porches, arcades and awnings, moderate the elements.

Rue St. Jean in the evening

Third, they’re connected. They lead somewhere. The streets that feel like what Kaid Benfield calls “people habitat” are usually hooked into the larger network, linked to the rest of the town.

Next, they’re safe. That means you aren’t stressed out about getting run over by a vehicle, because motoring speed is slower by design. You’re also safer if you have what Jane Jacobs called “eyes on the street.” The safe street isn’t faced by blank walls, but by doors and windows and porches and balconies and storefronts.

Lastly, the streets where people really like to be are memorable. They make lasting impressions because beauty surrounds us and human creativity is on display, in architecture and art and signs and landscape design. An artful spatial design, with composed vistas, ratchets up these powerful impressions.

The "public realm" is where our first impressions of your whole city are formed. In this video, urban designer Victor Dover outlines how these spaces between...

The public realm

Towns and cities speak to us through their outdoor spaces—the public realm, the world between the buildings. Those public spaces, whether street or parks or squares or plazas, are composed, given their shape and focus, by the design and placement of buildings and the landscape. There’s usually a sense of enclosure and completeness where the public realm is strong. Sometimes the space is narrow, sometimes wide, at times intimate, at times opening up to and contrasting with long vistas.

Street-oriented architecture is a vital ingredient for a positive experience in the public realm.

Your city is a communications device. It’s sending you a message. Is it welcoming people?

Wide or narrow, as you move about the neighborhood day to day, the public realm is where you’re spending your time. And when that public realm is thoughtfully planned and designed, it sends you a message of confidence and comfort and neighborliness. It’s where memories are made, where friends can meet, where ideas are exchanged, where commerce and art and culture and civic life intersect.

Caveat: It could be sending everyone the wrong message.

Warning: Your public realm could be sending all the wrong signals

It’s easy, however, to get it all terribly backwards, and when the public realm is starved for attention and quality, it sends exactly the opposite message: that this is a place where nobody cares, a message of uncertainty. The public realm is where our impressions of the whole city or countryside are formed— for good or ill.

The public realm is just as important in rural places

Experiences

What experience is your neighborhood offering?

The public realm is crucial everywhere, but it’s especially so in cities that need to attract population and investors for revitalization, and in tourist destinations. Give people a good experience, and they’ll return, and help you build a stronger economy, a better tax base, and a creative culture.

If you want people to return, your public realm has to exude confidence. The design is crucial.

The public realm matters, so whether you’re a mayor or a real estate developer or just a taxpayer, it needs your attention. That’s #8 on my list of Town Planning Stuff Everyone Needs to Know. For more information, check out the Dover Kohl YouTube channel. —Victor

Mixing Land Uses = Convenient Daily Lives (TPS Ep. 7)

A big part of the convenience and functionality of traditional towns comes from their mix of land uses. Episode 7 of Town Planning Stuff Everyone Needs to Know, “Mixing Land Uses,” reaches screens Monday, May 24 at 2pm. (Please share it, and subscribe to our YouTube channel to get notified about upcoming episodes. And, watch the episode for some cool new animations by Theresa Dover.)

Ever wonder why there's so much driving going on? What makes historic neighborhoods so popular? Watch this intro to the benefits of planning for mixed land u...

Instead of pushing the needs of daily life farther apart from one another—as became common in the suburban zoning experiment after World War II—the time-tested way of building a town is to deliberately bring a range of human activities closer together. That way, you can find many of the things you need right in your neighborhood, within walking distance.

For example, you might be able to walk from your home to a corner store or a café without having to drive there-- and without having to search for a parking space! Our client and collaborator, traditional neighborhood innovator Vince Graham, argues that “mixity” is more important than density when sizing up the impacts of development.

Just a little bit of mixed use brings many benefits:

Shorter Trips, More Workable Transit, Less Carbon

Some trips out on the regional road network get shortened. Others get eliminated, captured within the neighborhood. And still others become feasible for walking, biking or transit. All of that helps manage regional traffic. Plus, with those shorter trips you’ll lower everyone’s carbon footprint.

But that’s not all. Mixed land uses allow for organic, economic choices and change over time, letting the market have more sway over the mix. That, in turn, also supports the adaptive re-use of beloved historic buildings, extending their lifetime.

Balance, and Getting to Know the Neighbors

Live/Work combinations— also known as zero commute housing— and mixed land uses allow for a better jobs/housing balance, which can be key to a municipality’s sustainable tax base, lowering the costs for households, businesses and government. And above all, in a mixed-use neighborhood you’re simply more likely to get to know your neighbors and support local businesses. Psychologist Susan Pinker reports that studies definitively show what she calls The Village Effect: face-to-face interactions are crucial for a sense of contentment and for longevity, especially in an era when high tech devices tend to isolate us. She writes: "Neglecting to keep in close contact with people who are important to you is at least as dangerous to your health as a pack-­a-­day cigarette habit, hypertension or obesity."

The Italian island of Sardinia has more than six times as many centenarians as the mainland and ten times as many as North America. Why? According to psychologist Susan Pinker, it's not a sunny disposition or a low-fat, gluten-free diet that keeps the islanders healthy -- it's their emphasis on close personal relationships and face-to-face interactions.

For all these reasons and more, mixed-use neighborhoods are incredibly popular with both households and employers, attracting people and attracting jobs. That’s why Mixed Land Uses are #7 on my list of Town Planning Stuff Everyone Needs to Know.

Downtown: Shared by All (TPS Ep. 6)

, ,

Episode 6 of “Town Planning Stuff Everyone Needs to Know” is about downtowns, and it posts 5/18/2020 on our YouTube channel.

Have you ever stopped to think about which neighborhood is the most important one in your city?

The thing about a downtown is, it’s everybody’s. No matter where you live in a town, if your town’s downtown neighborhood is doing well you probably have a sense of shared ownership and pride in that place. 

When a town grows to the size of several adjoining neighborhoods, it will start to need (and deserve) some things that most individual neighborhoods can’t support all by themselves, like a larger central gathering place, or a Main Street, and seats for the most important shared civic institutions, like City Hall. In healthy cities these are almost always found among workplaces and housing and lodging and places to shop and eat in the downtown neighborhood or center.

When they’re allowed to, downtowns naturally evolve to become mixed-use, mixed-income, multi-modal precincts. Jane Jacobs put it this way:

“The [downtown], and indeed as many of its internal parts as possible, must serve more than one primary function; preferably more than two. These must insure the presence of people who go outdoors on different schedules and are in the place for different purposes, but who are able to use many facilities in common.”

“The Need for Mixed Primary Uses,” from The Death and Life of Great American Cities

Variety, planned on purpose, like you mean it

The wide variety in neighborhoods and building types within the core of a traditional city ultimately provides opportunities for people of all ages, backgrounds, cultures and income levels to live and work together. In contrast to suburban development, which generally offers only the single-family detached home, traditional cities offer a range of housing options, including single-family homes on smaller lots, rowhouses, garden apartments, the loft conversions that are transforming many former industrial districts, and, in some cases, midrise and highrise options for the people Frank Lloyd Wright once called “cliff dwellers.” Each of these housing types is located within mixed-use blocks, allowing for residents to meet their daily needs and conveniences in a dynamic urban neighborhood. As centers of commerce and trade, downtowns also provide an incredible variety of employment opportunities. With a city’s commercial and residential life follows cultural facilities and retail establishments. Young professionals, CEOs, students, doctors, government officials, shopkeepers, retirees, and families alike can all find their place in the heart of the city, due to the incredible diversity of jobs, housing types, cultural amenities, and (hopefully) varied means of transportation. This incredible range of land uses, housing types, employment, and income levels within a traditional urban fabric provides the freedom of choice, a privilege not afforded to residents of mono-functional suburbs.

Renaissance underway (but there is a catch)

Downtowns, even the ones that fell into decline 40 or 50 years ago, are naturally set up to once again become places where people want to be. But they need tender loving care. You must not force suburban zoning or parking requirements or street designs on your downtown, and if that’s happened already, your city is not alone, but it can join the ranks of the cities that have begun reversing the process.

The good news is, Americans have rediscovered their downtowns, in small villages, medium-sized towns, and big cities. According to Walkable Urbanism author Christopher Leinberger, half our downtowns are already revitalizing, and the other half soon will be. Your downtown is the most important neighborhood in your city, shared by all. And that’s #6 on my list of the Town Planning Stuff Everyone Should Know.
