Planners Must Now “Anticipate the Unanticipated”

“The planning practices of the past are inadequate for today’s challenges,” said David Rouse, ASLA, a landscape architect and planner, at the American Planning Association‘s National Planning Conference in San Diego. Rapid technological change, socio-economic inequities, natural resource depletion, and climate change are forcing planning and design professionals to adapt. “How can the practice of planning evolve to be more sustainable and equitable?”

In the 1920s, the Standard Zoning Enabling Act and the Standard City Enabling Act were passed. In the 1960s, the conventional 20th century planning model, which focused on land use policy and planning, came into being. In the 1980s, there was a shift to smart growth and “visionary, values-based planning.” In 2010, the American Planning Association began a process of rethinking past planning approaches through its Sustaining Places Initiative, which provided models and standards for how to prioritize sustainability through local planning.

According to Rouse, today’s comprehensive plans require a new 21st century model rooted in four key aspects. First, sustainability, resilience, and equity need to be at the center of all planning decisions. Second, a systems-thinking approach is needed. “A community is a system made up of sub-systems.” Third, any planning effort requires “authentic participation” and true community engagement that can answer the questions: “Where are we headed? Where do we want to go? How do we get there?” And lastly, there must be “accountable implementation,” including priorities for action, funding streams, policies that can guide decision-making, and specified responsibilities.

Rocky Piro, executive director of the Colorado Center for Sustainable Urbanism and former planning director of Denver, said Rouse and himself reviewed hundreds of plans for their new book — The Comprehensive Plan: Sustainable, Resilient, and Equitable Communities for the 21st Century. They found that “authentic engagement is foundational” to any new planning effort.

Planning processes must now include an engagement and communications strategy rooted in the issues and values of a community and be designed to reach all segments of a population. Any planning effort in 2022 also needs to be based in an understanding of the “impact of the past on the present.”

A vision statement is needed to kick-start these comprehensive planning efforts — “one with brevity, clarity, and the ability to inspire,” Piro said.

Land-use maps are still an important component of any comprehensive plan but they need to be smarter. In its plan adopted in 2012, Austin, Texas, created a “growth concept map” that includes places and their aspects (see image at top). Aurora, Colorado, included a “place typology” that includes a “sophisticated matrix” and a “place-based approach” in its plan.

All communities are systems that include natural, built environment, social, economic, health, and regional connection sub-systems.

“Planning for natural systems has come out of the landscape architecture field,” Rouse argued. “Ecosystem planning should now happen in communities and in context with other planning elements instead of piecemeal.”

Planners and landscape architects need to increasingly plan for land, water, atmospheric, and biodiversity change within communities. And instead of planning for water use and quality alone, an entire watershed approach should also be integrated into comprehensive planning efforts.

The ecosystem component that landscape architects focus on can be integrated with the built environment components that planners focus on. Through the involvement of multiple disciplines, plans can address “land use, character, ecology, mobility, community design, and civic spaces, and public art.”

Other important systems that need to be included in any new comprehensive plan are social systems that improve equity — “the social infrastructure” of communities, including housing and education.

Economic systems also need to be re-thought for the 21st century. “Economic resilience is about creating opportunities for all in a fair and sustainable way. We can move to a circular economy and rely on local assets and regional resources. We need to move away from a linear, throw-away society.”

Health systems need to be factored into any planning effort, and this is not just “about disease prevention, but about healthy transportation and food systems. How we move and interface with the built environment impacts our health.”

There are now many lens — a “climate lens, equity lens, health lens. Can we bring the lenses together?”

Both Rouse and Piro returned to the idea that any planning effort can only happen with real community engagement.

Once the voice of the community in its totality has been considered, then a plan can be developed that results in the revision of regulations, codes, and ordinances to help achieve that plan. The next steps are to shift public and private investments to meet goals, align interests and decision-making processes within communities, and form public, private, and non-profit sector partnerships that can lead implementation.

In the 21st century, planners need to be “prepare communities for change, be proactive, and take an integrated approach instead of just reacting,” Rouse said.

The challenge is that planners are also operating within a “cone of uncertainty.” In the short term, there are tactics that can be used to manage community change, which may be foreseen or unforeseen and therefore disruptive. In the medium term, planners can set strategies and plans. But over the long-term, they will need durable visions. “All of this planning must happen sequentially and simultaneously.”

In their book, Rouse and Piro outline five core themes, including equity and engagement, climate change mitigation and adaptation, systems thinking, people-centered technology, and effective implementation.

“Equity must be interwoven, and an equity lens must be brought to all goals. Climate resilience must be a guiding principle of all planning work. Technology must be harnessed to serve communities. Planning participation is about co-creation with the community,” Rouse said.

“Planning is an art and a science. Our jobs are to anticipate the unanticipated. How can we do it better?” Out of the hundreds of plans that Rouse and Piro reviewed, “we couldn’t find one that did this well. It’s a journey society — and planners — must take. It’s the future of comprehensive planning.”

During the Q&A, one audience member asked whether “top-down, paternalistic comprehensive plans” are a thing of the past. A city comprehensive plan assumes there is one community in agreement, whereas there are many communities with different interests. The antithesis of a comprehensive plan is a neighborhood plan.

Community engagement is critical to forging consensus as is transparency about budgets and timelines, Piro argued. Ensuring grassroots buy-in is the “path to success.” But neighborhood plans need to be integrated with comprehensive plans and implemented in tandem. “You need consistency and coordination.” Ecological, social, and other systems “can’t be addressed in isolation.”

Another audience member wondered how comprehensive plans can address the communities who have been displaced due to gentrification. “How do we plan for who is not there?”

Rouse argued that it’s critical to retain populations by helping them create their own visions. “We can account for the past and systemic racism,” and planners and other design professions’ roles in creating those inequities.

Secretary Buttigieg Offers Vision for Transportation Equity

At the Transportation Research Board (TRB)’s annual meeting in Washington, D.C., Transportation Secretary Pete Buttigieg outlined a vision for designing a more equitable and sustainable transportation system. Leveraging the historic levels of funding available through the recently passed Infrastructure Investment & Jobs Act, Secretary Buttigieg said funds must be distributed in order to simultaneously create jobs, address the climate crisis and racial inequities, and reduce road traffic deaths.

The Infrastructure Investment & Jobs Act provides an enormous opportunity to improve both large cities and small communities. “The law contains some of the most significant investments in our transportation infrastructure in generations. These investments are going to have a very real impact on daily lives. They are going to put people to work, reconnect communities, and save lives.”

But the “promise” of the infrastructure bill also “depends on whether we succeed in making the most of these investments.”

For example, transportation policy needs to be intentionally framed to increase jobs and economic development. “Income inequality had been rising long before the pandemic. Good transportation policy directly and indirectly creates jobs that help families build generational wealth for the future. The key is creating opportunities that reach people in places where they are most needed. Last year, I visited the tunnels underneath Atlanta’s international airport, which helped create a thriving Black middle class during its construction, simply by ensuring communities of color had a seat at the table when it came time to award the contracts to build that airfield in the first place.”

A focus on ensuring equitable access to both transportation and the economic opportunities that come with the new federal investment was woven throughout his speech. “Every transportation decision is inherently a decision about equity. That’s why we’re building equity into our grant criteria.”

He added that “transportation and racial equality are two stories that go together. We want to proactively work with communities seeking to do the right thing, over and above the legal minimum.” Another part of this approach is increasing partnerships with diverse small and medium-sized businesses, so there are “partners ready to run with opportunities.”

New transportation policy must also address past climate and environmental injustices: “We have a commitment, as an administration, to ensure 40 percent of the benefits of climate and clean energy investments go to underserved and overburdened communities.”

And he gave his support for advancing universal design through the All Stations Accessibility Program (ASAP) Act of 2021, championed by Senator Tammy Duckworth, which would fund more transit facilities becoming ADA-compliant.

Shifting to climate, TRB noted that transportation now accounts for nearly 30 percent of total U.S. greenhouse gas emissions. Secretary Buttigieg said given transportation is the single largest sector contributing to the climate crisis, “we have an obligation to strive to be the biggest part of the solution.”

When asked what are the best ways to decarbonize transportation, he highlighted the kinds of planning and design solutions landscape architects provide: “We really need to think about every dimension of a trip, and what can be done to make it greener. Can we use design to reduce the necessity of some of thetrips people take? When people take trips, can we create alternatives so they can take those trips in other modes?”

And he focused on other strategies landscape architects plan and design to advance climate goals. “Housing and transportation policy has to fit together. Transit-oriented development is a climate opportunity as well as a planning concern. All of these things have be considered together in an integrated way. That’s something you already see in the most forward-thinking communities.”

Secretary Buttigieg also explained how electric vehicles, and the charging infrastructure to support them, along with co-siting large-scale renewable power plants with new transportation systems will be key to a more sustainable future.

As part of the combined strategy to advance goals on jobs, equity, and climate, safety also remains the “fundamental mission of this department,” Buttigieg said. “We lose 3,000 people every month to traffic crashes. We must confront the fact that these tragic deaths are not inevitable, but preventable. We need to take new steps, like a safe systems approach nationwide.” Soon the department will be releasing its first national roadway safety strategy.

“If we do this right, we’ll look back on the 2020s as a period when transportation equity reached new levels. That makes not only historically excluded groups better off, but the whole country better off, because we’ll have a stronger, more stable, richer, fairer economy for all.”

The Case for the Rural-to-Urban Transect

Transect Urbanism: Readings in Human Ecology / ORO Editions

By Grace Mitchell Tada

Imagine a tool that banishes the social and environmental ills of modern urban planning and its suburban sprawl, instead constructing an approach that reconciles urbanism and environmentalism. Meanwhile, the tool also enables choice and equity in how and where individuals live.

Architect, urban designer, and DPZ CoDesign principal Andrés Duany insists such a tool exists. It’s the Rural-to-Urban Transect, at once a tool and a theory, and it’s a balm to the recklessly sprawling modern life now ubiquitous across the U.S., which takes the form of socio-economic uniformity, automobile dependence, and conspicuous land consumption.

The book Transect Urbanism: Readings in Human Ecology, edited by Duany and Brian Falk, who is director of the Center for Applied Transect Studies, presents a collection of essays and descriptive graphics that examine the Rural-to-Urban Transect and explains its potential to create both a better quality of life within communities and better environmental practices across all scales.

This transect identifies and allocates elements of urbanism and their suitability to varying environments. It’s a theory of human settlement: an “ordering system” that harnesses a geographic gradient to organize natural habitats, including human habitats. Every human activity, and its resulting element in the urban fabric, can be pegged to a locus somewhere along that gradient. These elements comprise an “interrelated continuum of natural and human habitats—natural, rural-sub-urban, and urban—with different settlement densities and opportunities for social encounter and human activity,” the authors write.

Though the concept of a transect was not defined as such until the 18th century, Duany describes it as a pattern of human settlement both timeless and cross-cultural: the rural-to-urban spectrum can be traced to settlements from ancient Pompeii to ancient China.

In the late 18th century, Alexander von Humboldt first articulated the transect in the modern sense. Joseph Meyer illustrated the concept, drawing Humboldt’s voyage to South America to include the natural habitat and conditions above and below the ground’s surface.

In the 19th century, Sir Patrick Geddes’ illustrated “Valley Section” incorporated human presence in varying habitat zones. The humans, per the times, always exploited their environment.

“Valley Section,” Sir Patrick Geddes / Center for Applied Transect Studies

In 1969, Ian McHarg posited the next seminal transect. Duany finds it incomplete: it failed to include, or even suggest, human habitat. Moreover, this absence perpetuated the dualism between human and nature that underpins environmental thinking — “nature is sacred, and the city profane.” This dualism ultimately produced the chasm between environmentalism and urbanism.

In practice, McHarg-inspired planning has yielded countless communities that prioritize preserved “environmental” areas at the expense of higher density. For example, South Carolina’s Hilton Head and California’s Sea Ranch sanction only single-use zoning. “The developed areas of these projects remain, in their socioeconomic and environmental performance, indistinguishable from sprawl: everyone drives everywhere for everything,” Duany and Falk write.

Ian McHarg’s Natural Transect / Center for Applied Transect Studies

In 1994, the transect was revitalized as an ordering system at the Congress for the New Urbanism (CNU), when the group — proponents of “density, connectivity, and contiguity” — sought a theory establishing connections between elements of urbanism. The Rural-to-Urban Transect did so by defining six recognizable transect zones and their interrelationships: Natural (T1), Rural (T2), Sub-urban (T3), General Urban (T4), Urban Center (T5), and Urban Core (T6).

The Rural-to-Urban Transect / Center for Applied Transect Studies

Duany asserts that the Rural-to-Urban Transect extends “the environmental protocol of McHarg into the city,” thus including people. It becomes a tool with which to design, correlating elements along a rural-to-urban continuum, enabling “the basis for a system of zoning that creates complex, contextually appropriate human environments.” Adapted from landscape ecology, each of the six transect zones contain elements that engender and amplify a place’s character.

This transect’s extension of the McHargian protocol yields arguably two of its greatest boons: its potential to unite environmentalism and urbanism and its capacity to support diverse, equitable communities. The divide between humans and nature is not new — Duany traces this chasm back to the Old Testament — and it manifests in the 20th century as environmentalism’s defensive stance toward urbanism.

The dominant ecological disposition “privileges a pristine nature and regards the presence of humans as a disturbance” to a system understood according to its pre-human condition. “A good human community can be ‘green’ only by being invisible,” Duany and Falk argue. Urbanism has thus been viewed as “a negative condition, never as an organization of positive choices for the improvement of human communities.” And as a result, environmentalism is expressed in technical and regulatory systems that promote suburbanization — from pervasive landscaping to mandated on-site stormwater treatment.

This paradigm fails communities when prioritizing nature means seeing “social space as blight.” “Whole communities of humans have been pushed aside for highway construction, but certain fish and fowl have caused even the most single-minded transportation department officials to reconsider their designs,” Duany and Falk contend. But only certain communities get pushed aside. Favoring nature also usually translates to favoring certain social and racial groups at the expense of others.

According to the authors, their Rural-to-Urban Transect can mitigate these insidious tendencies. Rather than holding economy and culture as beyond nature, this transect accommodates all elements, rooted in the belief that humans are essential to environmental discourse, in all their various lifestyles along the rural-to-urban spectrum.

Most importantly, Duany and the other authors include everyone in their conception and explicitly those who historically have had little choice in how they live. Systems based in the Rural-to-Urban Transect encourage a plurality of viewpoints and human habitats. They promote equity.

Key to the Rural-to-Urban Transect is its basis in form. Many planning initiatives are based in use and therefore manifest as prohibitions and separation. Cities filter community-making through a sieve of engineering standards, zoning ordinances, and other regulatory mechanisms long before designers enter the scene. Duany asserts that this existing framework, however, can be re-imagined by their transect: zoning based in form can yield certain physical outcomes and settlement patterns. Rather than zones that simplify and separate, transect code ensures fruitful relationships and adjacencies, from the local to regional scale. Transect-inspired zones preserve character and diversity according to place.

Essays in Transect Urbanism explain how these successes of the transect can be achieved: one details how to analyze an urban transect, one discusses governance along the transect, another discusses retail models within it. Duany includes a chapter describing the transect-based SmartCode that he has developed and implemented across various cities. Another chapter gives hope that existing sprawl can be repaired into a paradigm more resilient. Other essays consider the Rural-to-Urban Transect ontologically: the reason for six zones, and whether it qualifies as natural law, as certain people — Duany included — claim. The range of essays, from the practical to the theoretical, and the extensive illustrations make it a book suited for the student and the professional, for the planner, the landscape architect, and others thinking critically about the built environment.

As of 2019, the Form-Based Codes Institute identified 439 transect-based codes that had been adopted worldwide. Clearly, more communities do not embrace such thinking than do, and our society has much work to accomplish before divorcing itself from suburban sprawl. Duany in part blames the theory of landscape urbanism, which he claims perpetuates sprawl through the guise of aesthetics. He argues: “human biophilia is such that an image of anything with leaves will tilt the selection in its favor.”

Certainly, though, criticisms of the Rural-to Urban Transect arise: it is too simplified; its mere six zones are insufficient to account for all settlement and natural area types; the intentional rules of its zones are undesirably prescriptive; or it lacks consideration of urban ecology and biodiversity.

Yet, as made by the case presented in Transect Urbanism, the Rural-to-Urban Transect can serve as a noble tool in the reformation of our urban fabric. In one of his essays, written in 2005, Duany warns that a failure to square environmental ethos and social equity concerns with free market choice as perpetuated by the status-quo sprawl may only be solved by “a long economic emergency…that none of us should wish upon the nation.”

As millions of Americans grapple with job and home losses, among many other kinds of loss, we’re in the midst of an emergency. Released into a pandemic climate that has made us skeptical of dense urbanism, this book arrives with special urgency.

Now is as ripe a time as ever to give a different paradigm a chance, even if doing so will also require specific and convincing accommodations to the moment.

Suburban Sprawl Increases the Risk of Future Pandemics

By Michael Grove, ASLA

The export of American culture is one of the most influential forces in our interconnected world. From Dakar to Delhi, American pop music, movies, and artery-clogging cuisine is ubiquitous. However, one of the most damaging exports is the American suburb. When the 20th century model for housing the swelling populations of Long Island and Los Angeles translates to 21st century Kinshasa and Kuala Lumpur, the American way of life may very well be our downfall.

In our pre-pandemic ignorance, most urbanists pointed to climate change as the most dangerous impact of our cherished suburban lifestyle. To be sure, the higher greenhouse gas emissions and rise in chronic health problems associated with living in subdivisions aren’t going away, but COVID-19 has exposed another threat we’ve chosen to ignore. The next pandemic may very well result from our addiction to—and exportation of—sprawl.

Vilifying Density and Disregarding Equity

The increasing traction of the anti-density movement in the wake of the current outbreak is alarming. Headlines proclaiming how sprawl may save us and that living in cities puts citizens at higher risk for contracting the novel coronavirus are deceptive.

Recent studies have debunked these myths, finding little correlation between population density in cities and rates of COVID-19, instead attributing the spread of the virus to overcrowding due to inequity and delays in governmental responsiveness.

Mounting evidence suggests that COVID-19 is primarily transmitted through close contact in enclosed spaces. Internal population density within buildings and, more specifically, within shared rooms inside buildings is what drives this, not the compact urban form of the city. In New York, for example, COVID-19 cases are concentrated in the outer boroughs, and suburban Westchester and Rockland counties have reported nearly triple the rate per capita than those of Manhattan.

The real issue is the systemic economic inequity that forces lower income people to live in overcrowded conditions, regardless of location. Innovative approaches to urban planning, equitable housing policies, and a reversal of over a century of environmental discrimination in our cities are absolutely necessary. Vilifying the city is counterproductive.

Moving out of dense cities into the open space and social distancing afforded by the suburbs is exactly the type of knee-jerk reaction that we must avoid. Cities are not at fault.

Habitat Fragmentation and Biodiversity Loss

In fact, cities are the answer if we plan them carefully. Among the many human activities that cause habitat loss, urban development produces some of the greatest local extinction rates and has a more permanent impact. For example, habitat lost due to farming and logging can be restored, whereas urbanized areas not only persist but continue to expand.

The Atlas for the End of the World, conceived by Richard Weller, ASLA, a professor of landscape architecture at the University of Pennsylvania, is one of the best sources for documenting our collective risk. Mapping 391 of the planet’s terrestrial eco-regions, this research identified 423 cities with a population of over 300,000 inhabitants situated within 36 biodiversity hotspots. Using data modelling from the Seto Lab at Yale University, the Atlas predicts that 383 of these cities—about 90 percent —will likely continue to expand into previously undisturbed habitats.

When we assault the wild places that harbor so much biodiversity in the pursuit of development, we disregard a significant aspect of this biodiversity—the unseen domain of undocumented viruses and pathogens.

According to the World Health Organization, approximately 75 percent of emerging infectious diseases in humans are zoonotic, meaning that they are transmitted to us through contact with animals. The initial emergence of many of these zoonotic diseases have been tracked to the parts of the world with the greatest biodiversity, both in the traditional and man-made sense. Traditional locations include tropical rainforests where biodiversity naturally occurs. Human-influenced conditions include places like bushmeat markets in Africa or the wet markets of Asia, where we are mixing trapped exotic animals with humans, often in astonishingly unsanitary conditions.

However, degraded habitats of any kind can create conditions for viruses to cross over, whether in Accra or Austin. The disruption of habitat to support our suburban lifestyle is bringing us closer to species with which we have rarely had contact. By infringing on these ecosystems, we reduce the natural barriers between humans and host species, creating ideal conditions for diseases to spread. These microbes are not naturally human pathogens. They become human pathogens because we offer them that opportunity.

This is already evident in the fragmented forests of many American suburbs where development patterns have altered the natural cycle of the pathogen that causes Lyme disease. When humans live in close proximity to these disrupted ecosystems, they are more likely to get bitten by a tick carrying the Lyme bacteria. When biodiversity is reduced, these diluted systems allow for species like rodents and bats—some of the most likely to promote the transmission of pathogens—to thrive.

This essentially means that the more habitats we disturb, the more danger we are in by tapping into various virus reservoirs. COVID-19 is not the first disease to cross over from animal to human populations, but it is likely a harbinger of more mass pandemics and further disruptions to the global economy. The more densely we build, the more land we can conserve for nature to thrive, potentially reducing our risk of another pandemic from a novel virus.

Portland’s Urban Growth Boundary

In the United States, over 50 percent of the population lives in suburbs, covering more land than the combined total of national and state parks. Our urbanization is ubiquitous and endangers more species than any other human activity.

In 1979, Portland, Oregon offered a pioneering solution with the creation of an Urban Growth Boundary (UGB). Devised by a 3-county, 24-city regional planning authority, the intent was to protect agricultural lands, encourage urban density, and limit unchecked sprawl.

Forty years into this experiment, Portland’s experience is a mixed bag of successes and missed opportunities. Investment in public transit and urban parks has certainly bolstered the city’s reputation as a leader in urban innovation, sustainability, and livability, with statistics to support its efforts.

On the other hand, two of Oregon’s fastest growing cities are situated just beyond the boundary’s jurisdiction, underscoring the limitations of the strategy. Again, inequity rears its ugly head, with higher prices within the UGB caused, in part, by an inability to deregulate Portland’s low density neighborhoods. This has driven much of the regional population further afield to find affordable housing in the form of suburban sprawl beyond the UGB’s dominion and into even more remote areas.

Another consideration that was overlooked when the original plan was established was the adequate protection of remnant habitat within the UGB. This lack of a regional plan for biodiversity protection has underscored the need for a more ecologically-focused, science-based approach to inform planning decisions.

Brisbane’s Bird Population

Unfortunately, anticipating outcomes of urbanization on species diversity is not as pervasive in urban planning agencies around the world as it should be. A lack of detailed modeling specific to individual regions and cities with clear recommendations for how to minimize ecological devastation is absent from planning policy around the world.

However, researchers in Brisbane, Australia have attempted to quantify which development style—concentrated urban intensity or suburban sprawl—has a greater ecological consequences. By measuring species distribution, the study predicted the effect on bird populations when adding nearly 85,000 new dwelling units in the city. Their results demonstrated that urban growth of any type reduces bird distributions overall, but compact development substantially slows these reductions.

Sensitive species particularly benefited from compact development because remnant habitats remained intact, with predominantly non-native species thriving in sprawling development conditions. These results suggest that cities with denser footprints—even if their suburbs offer abundant open space—would experience a steep decline in biodiversity.

This is a common outcome found in similar studies around the world that exhibit a comparable decline in the species richness of multiple taxa along the rural-urban gradient. Although biodiversity is lowest within the urban core, the trade-off of preserving as much remnant natural habitat as possible almost always results in greater regional biodiversity.

Helsinki’s Biodiversity Database

One of Europe’s fasted growing cities, Helsinki faces similar pressures for new housing and traffic connections as many other major metropolises. However, in Helsinki, geotechnical and topographic constraints, coupled with its 20th century expansion along two railway lines rather than a web of highways, created the base for its finger-like urban and landscape structure. Today, one-third of Helsinki’s land area is open space, 63 percent of which is contiguous urban forest.

In 2001, Finland established an open source National Biodiversity Database that compiles multiple data sets ranging from detailed environmental studies to observations of citizen scientists. This extraordinary access to information has allowed the city to measure numerous data points within various conservation area boundaries, including statistics related to the protection of individual sites and species.

Measured by several taxonomies, including vascular plants, birds, fungi, and pollinators, Helsinki has an unusually high biodiversity when compared to neighboring municipalities or to other temperate European cities and towns. Vascular plant species, for example, average over 350 species per square kilometer, as compared to Berlin and Vienna’s average of about 200 species. By embracing biodiversity within the structure of the city, not only is the importance of regional biodiversity codified into the general master plan, it is also embedded into the civic discourse of its citizens.

When it comes to where the next virus might emerge, Wuhan isn’t really that different from Washington, D.C. If the American model of over-indulgent suburban sprawl is the benchmark for individual success, we all lose.

Now is the moment to put the health of the planet before American values of heaven on a half-acre. Land use policies in the United States have just as profound an impact on the rest of the world as any movie out of Hollywood.

If we shift American values toward embracing denser, cleaner, and more efficient cities that drive ecological conservation—instead of promoting sprawl as a panacea for our current predicament—that may very well be our greatest export to humanity.

After Lockdown, New Opportunities for Downtown Shopping Districts

By Robert Gibbs, FASLA

Since the earliest human settlements, the retail experience has evolved to meet the needs of the public. This evolution has taken us from rural markets to towns, cities, suburban shopping malls, big box mega-stores, and, more recently, the Internet. But what will retail shopping look like once COVID-19 lockdowns are over and people return to the wild for their shopping experiences?

When all the dust settles, the post-lockdown era should provide a boost to downtown areas, in part due to newly unemployed but highly skilled restaurant and retail workers opening new businesses in downtowns where rent prices will trend downward.

The pandemic has left millions of highly skilled workers from the retail and food and beverage industries unemployed and eager to work. Many of these people are highly motivated to start their own businesses, creating an unparalleled pool of talent and potential entrepreneurial interest.

In a recent Forbes article, Bernhard Schroeder wrote: “27 million working-age Americans, nearly 14 percent, are starting or running new businesses. And Millennials and Gen-Z are driving higher interest in entrepreneurship as 51 percent of the working population now believes that there are actually good opportunities to start companies.”

Traditionally, fear of failure has held people back from starting a business, but with so many having their jobs swept away due to the pandemic, that fear is gone for many people, who realize they no longer want to rely on an employer for the rest of their careers, and instead want to take on the challenge of leading their own companies.

Downtown shopping districts will capture traffic from fading malls

Malls will struggle in the era of COVID-19. Being inside an enclosed bubble will not be the ideal situation for most shoppers for the foreseeable future. Morning Consult reports that 24 percent of U.S. consumers fear shopping in malls for at least the next six months due to the COVID-19 threat.

As an article about a newly reopened mall in Atlanta explains, the experience won’t be very welcoming in the near term. Play areas are roped off, water fountains covered, and stores are limiting the number of shoppers due to social distancing. Add in the inconvenience factor, and it’s clear why so many malls are facing a reckoning in the coming years.

As regional malls continue losing consumers due to changing shopping habits and fears of COVID-19, an excellent opportunity presents itself for villages, towns, and cities to regain their dominance as thriving centers for retail and entertainment.

Some factors to consider:

  • As Millennials and Empty Nesters seek to live, work, and shop in urban centers, medium-sized cities (100,000 to 200,000 population) are especially likely to benefit from this trend.
  • Small towns (10,000 to 20,000 people) located near large urban centers are also appealing to start-up retailers and restaurants that want to take advantage of their proximity to large, well-heeled populations and small towns’ affordable commercial storefronts.
  • New walkable town centers — planned with authentic urbanism and a variety of hospitality, employment and residential land use — can also ride the wave of Millennials, young families, and Empty Nesters who seek an exciting place to hang out.

Main Streets are already innovating

Main Streets have been reinventing themselves in a positive way during the past few decades, making them a more attractive alternative for retail shopping in the era of COVID-19.

These innovations include:

  • Updated master plans that undo blight caused by 1970s urban renewal plans.
  • Implementation of Downtown Development Districts, which offer marketing, promotions, special events, street cleaning, landscaping, flowers, and private-sector levels of management.
  • Effective parking management, and construction of new parking lots and garages.
  • Investment in beautiful new streetscapes, public art, and street furnishings.
  • Reduction of crime, increased safety.
  • U.S. Main Street programs, which offers guidance to revitalize downtowns, and returns $36 for each $1 invested.

For Millennials, who seek more social experiences as opposed to the enclosed mall experience of their youth, Main Street experiences in their towns and cities are the perfect fit for their lifestyle.

While the larger portion of their income will go to experiences such as European travel or outdoor adventures, closer-to-home visits to a local brewpub or coffee shop in their town center make perfect sense.

Main Streets will provide new homes for mall stores

As malls close and online shopping grows, existing mall retailers will seek new locations near their former mall stores. In many instances, these venues include smaller downtown cores, which traditionally offer lower rents and, now, the safety of an open-air shopping experience.

The writing is on the wall for mall store operators, all of which leads to an economically-friendly, Main Street setting:

  • Malls depend on department stores to attract almost 50 percent of their shoppers and cannot operate without them, which is problematic for many reasons.
  • Many mall retailers have lease options allowing them to break their leases and leave the mall should key department stores close.
  • Department stores are losing market share, from a peak of 50 percent of all retail sales in the 1950s to 5 percent today.
  • Since the heyday of malls in 1992, department store sales have dropped from $230 billion to $140 billion and many department stores are close to bankruptcy.
  • Over 50 percent of regional malls are forecast to close by 2025 (Credit Suisse).

Retail and office space will move to town centers

The online shopping boom has made nearly obsolete many of the conventional large power center retailers offering products such as books, electronics, office supplies, sporting goods, and toys. The end result is the expected closing of millions of square feet of retail space.

Often, these centers cover typically 20-50 acres of prime real estate, which presents an opportunity. They can be converted into mixed-use town centers with medium density residential and commercial occupants.

The same can be said of suburban office parks, as even centers in blue-chip locations are facing high vacancies and declining rents as many major corporations are moving into city centers to attract top talent. Millennials find the suburban office parks boring, preferring to live and work in downtowns. These large office parks have an abundance of land and parking that can be retrofitted into walkable mixed-use town centers.

Challenges and opportunities for downtown shopping districts

Challenges: When a national brand relocates from a mall environment to a town or city, they may initially receive a cold shoulder from city leaders and the community, who fear popular brands will end up killing their beloved Main Street’s unique charm.

Looking back at history, though, this thinking is inaccurate, as downtown shopping districts were filled with leading retailers and large department stores during their 1950s heyday. For long-term sustainability, a downtown should always offer the goods and services desired by its residents and workers, which may include popular brand names.

Zoning is another key battle. Cities must offer flexible form-based zoning to allow for medium-to-high densities of residential and commercial to be developed as walkable neighborhoods and business districts. Development standards should focus on requiring quality design and materials, rather than arbitrary minimal units per acre densities, minimal parking ratios, or suburban building setbacks.

Parking needs to be reconfigured to allow shoppers to pickup goods curbside.

Opportunities: downtowns and open-air town centers are seen as safer from the pandemic than enclosed malls, because they offer:

  • Wider spaces.
  • Less-enclosed spaces, with more fresh air and direct sunlight.
  • The ability to walk on other side of street or block.
  • No elevators or escalators.
  • Fewer doors to enter.
  • Curbside pick-up of goods.

People enjoy visiting towns and cities to socialize and experience parks, urban life, including storefronts.

They visit to have an experience they cannot get through online shopping. And while visiting downtowns for entertainment and fun, many will walk by store fronts and be tempted to make impulse purchases from Main Street retailers.

Towns and small city landlords typically offer much cheaper rents than suburban malls, often more than 50 percent less, and also offer flexible lease terms: no minimum hours and less rigorous storefront and merchandising standards than mall leases. This type of accommodation will be more attractive to new entrepreneurs created from this pandemic.

The savings also are appealing to national retailers facing declining sales and mall leases that are too expensive.

How downtown Main Streets can ensure success

As we look to the future, and the economic recovery that will come once a vaccine is created and herd immunity is established, all signs point to the re-emergence of Main Street as the place people will want to do their retail shopping.

A new generation of entrepreneurs will be eager to start a new chapter in their life, and the suburban shopping centers are not going to attract them.

Well-designed town centers, with the type of social interaction sought by Millennials, young families, and Empty Nesters will be the new home for the boom in the years to come.

A few best practices for downtowns to apply:

  • Create a marketing strategy for a post-pandemic campaign.
  • Beautify the public realm through landscape, lighting, parking lots-garages, signage, streetscape, and storefront improvements.
  • Explore temporary commercial street closures to allow for open air dining and shopping spaces.
  • Modify zoning to allow first floor office and service business.
  • Require store fronts to maintain large clear glazing, sign bands, operating doors, and ceiling heights to allow for future retail or restaurant use.
  • Remove or reduce minimum retail and restaurant parking requirements in downtowns and new mixed-use developments.
  • Include generous 10-minute parking spaces to accommodate curbside pickups for restaurants and retailers.
  • Devise market-based business recruitment plans and resources to identify and attract new retailers and restaurants into the downtown.
  • Seek a balance of local, regional, and national retailers.
  • Apply flexible zoning to promote medium-density and high-density multi-family residential.
  • Implement market based master plans, form-based codes, and zoning flexibility to allow for retrofitting of underutilized shopping centers and office parks.

How Can Cities Best Plan for Future Growth?

The world’s cities are growing at a rapid pace. By 2030, nearly 70 percent of people will live in urban areas. Cities not only face immense challenges related to climate change, migration, mobility, infrastructure, equity, and security, but are also dealing with the problems associated with scaling up to meet rapid growth.

So how can cities better plan for future challenges and growth? Dr. Blair Ruble, distinguished scholar at the Woodrow Wilson Center, tried to answer that question by illustrating ways cities are grappling with the new reality, in a discussion at the World Affairs Council in San Francisco, which was moderated by Gordon Feller, founder of Meeting of the Minds, a non-profit network focused on cities.

First, Ruble said, growth must be accommodated through the right framework. “We have a very good example in our own country. In 1811, a bunch of commissioners sat down and planned a grid for an empty island of Manhattan. They created a framework, and that’s the mode we need to get into when we talk about the future of cities.”

But the amount of future planning needed is incredible. “When you think about a billion people and limited resources in the context of a planet struggling with climate change and migration, you realize this is an enormous challenge,” he said.

A silver lining might be where the growth is happening. In the U.S., where the population will be 400 million by 2050, most growth will occur in secondary cities. “Mega-cities have actually kind of plateaued,” Ruble said. “Most of the growth in cities right now is taking place in so-called medium cities of 5 to 10 million people.” Mid-sized cities’ manageable population size leaves an opportunity for more thoughtful development and policies that can enable sustainable urban growth.

As an example, Ruble pointed to future settlement planning in the Central Asian country of Kazakstan, as well as efforts to retrofit existing infrastructure in Africa and South America. Cities there have enabled government services to be available in self-built neighborhoods.

In addition to integrating a growing number of people, cities are grappling with a massive flow of data. Ruble said unless cities focus on the human component of data collection, they can be caught up in collecting data for data’s sake.

“The actual numbers are not the end themselves,” Ruble said. “Cities don’t just exist to generate data for analysts to play with. Connected to each information point is a human being.”

Issues of inequality should be front and center in any discussion of urban challenges. 

Take Toronto, and Canada more broadly. There is generally a more multicultural definition of citizenship than in the U.S. Still, racial inequality persists. Ruble pointed to a 2017 survey on the state of the Black population in Toronto showing 72 percent of respondents between ages 20 and 40 who identified as Black had been stopped by police; and data shows Blacks are “much more likely to be shot by police” than any other group.

“To address that problem, you can use all the technology you want, but if you don’t begin to get real about the limitations of your own vision of multiculturalism, the technology isn’t going to help.”

Flexible urban systems will be key to recognizing challenges and issues as they arise and adjusting course. “Urban success is not a noun, it’s a verb,” Ruble said.
