American Planning Association 2013 Conference: Sustainable Street Network
American Planning Association 2013 Conference: Sustainable Street Network
Joseph Readdy of Schemata Workshop was invited to participate in a panel at the 2013 American Planning Association national planning conference – Plan Big Chicago. Our panel was devoted to the principles of a sustainable street network. The panel was organized and moderated by Heather Smith, planning director for the Congress for the New Urbanism. The other panel members included Jacky Grimshaw, vice president of the Center for Neighborhood Technology and Marcy McInelly, principal at Urbsworks, Inc. The topic of our panel was to challenge planners to reevaluate their transportation plans and policies and rethink their approach to the design of their streets in their communities. This is my presentation:
A Hypothesis and a Call to Action
I enjoy logic problems. I’ll often start my morning finishing my coffee and solving the Sudoku puzzle in The Oregonian or the crossword in The New York Times. But logic problems like those are not adequate preparation for urban design or transportation planning. Logic problems like ken-ken, sudoku, or the crossword puzzle are considered “tame,” while urban design problems exhibit all of the characteristics of a “wicked problem.”
the Saturday puzzle
"Wicked problem" is a phrase coined originally by two professors from UC Berkeley for use in social planning to describe any problem that is difficult or impossible to solve because of incomplete, contradictory, and changing determinants that are often difficult to recognize or not immediately apparent. The term ‘wicked’ is used, not in the sense of evil but rather its resistance to resolution. Professors Horst Rittel and Melvin M. Webber developed the concept of wicked problems in a 1973 treatise, contrasting "wicked" problems with relatively "tame," soluble problems in mathematics, chess, or puzzle solving. Their formulation of wicked problems in social policy planning specified ten characteristics. In the graduate seminar that I developed and teach at Portland State University, I’ve developed four principles for the wicked problem that helps describe their role in urban design and transportation:
1. each wicked problem is not fully understood until after the formulation of a solution;
2. stakeholders may have radically different world views and vastly different frames of reference for understanding the wicked problem, so a solution to some stakeholders is not a solution for other stakeholders;
3. constraints and resources to solve a wicked problem will change over the course of formulating a solution; and
4. the problem is never solved.
In my experience, each of these principles feels true and captures a fundamental challenge of urban design problems. Of the four, the last makes the point that many in the design profession fail to perceive to the detriment of our cities and the social, cultural, and economic exchange that they are meant to foster and support. Early modern architects applied their knowledge, experience, and skills to the environmental degradation and squalor of the early 20th century city, especially those issues of extreme poverty and social housing. I am convinced that because the solutions that they envisioned were intended to eradicate for all time these problems, their belief in a perfect solution that would endure for all time was a fundamental and fatal flaw, as was their goal of an international –or placeless and timeless– approach to design.

“Some problems are so complex that you have to be highly intelligent and well informed just to be undecided about them.”
Strategies to tackle wicked problems
Wicked problems defy a traditional approach to problem solving in which problems are defined, analyzed, and overcome in discrete, sequential, and logical steps because there is never a clear, concise, and complete definition of a wicked problem. There are three strategies to cope with wicked problems:
Authoritative
These strategies seek to tame wicked problems by vesting the responsibility for solving the problems in the hands of a few people. The reduction in the number of stakeholders reduces problem complexity, as many competing points of view are eliminated at the start. The disadvantage is that authorities and experts charged with solving the problem may not have an appreciation of all the perspectives needed to tackle the problem.
Competitive
These strategies attempt to solve wicked problems by pitting opposing points of view against each other, requiring parties that hold these views to come up with their preferred solutions. The advantage of this approach is that different solutions can be weighed up against each other and the best one chosen. The disadvantage is that this adversarial approach creates a confrontational environment in which knowledge sharing is discouraged. Consequently, the parties involved may not have an incentive to come up with their best possible solution.
Collaborative
These strategies aim to engage all stakeholders to find the best possible solution for all. Typically these approaches involve meetings in which all parties have equal standing and all issues and ideas are discussed and thoroughly understood before a common approach is formulated for implementation. I believe that only a collaborative approach truly offers the best opportunities for successful engagement of urban design problems.
In a 1972 paper, Rittel hints at a collaborative approach; one which attempts, "…to make those people who are being affected into participants of the planning process . They are not merely asked but actively involved in the planning process…" In her 2000 paper, Nancy C. Roberts, Professor in the School of Information Sciences at the Naval Postgraduate School in Monterey, California, says of solutions to wicked problems, “We learn to take care in attempting to tame wicked problems by turning them over to experts or some center of power for definition and solution. If we are truly dealing with wicked problems when no one is “in control,” then it is unlikely that the experts and leaders will be able to act unilaterally to define the problems and their solutions. In fact, their insistence in doing so may impede the problem solving process. We learn that wicked problems are socially defined so that getting the “whole system in the room” to enable people to learn from one another is very useful.” In other words, a collaborative and inclusive approach will yield better, more intelligent, more robust solutions to our wicked problems.
Hypothesis:
If the fundamental purpose of cities is to maximize social, cultural, and economic exchange, then we must change the way that we design our streets. We’ve been defaulting to the authoritative approach for the design of our streets for too long. We’ve been giving the design of these important parts of our public realm to our “experts” who apply their knowledge, tools, and training to their design at the expense of place. The tools that we are currently using to illustrate street design results in a street network that:
- prioritizes the free flow of automobiles;
- is resource intensive or wasteful – both initially and long-term;
- contributes to our sedentary lifestyle and the chronic diseases that arise from it;
- unfairly burdens both the young, the old, the poor and people of color; and
- diminishes the social, cultural, and economic exchange that we seek.
Streets in our cities serve two essential functions: to connect people to destinations and to be places in and of themselves. When we design to connect people to these destinations, we seem to plan for destinations that are too far apart to make effective use of walking, biking, or transit as alternatives to the automobile. Yet, more than half of all trips in the United States are three miles or less; forty percent of all trips are two miles or less; and nearly thirty percent of all trips are one mile or less. Yet we design our streets as if every trip was a marathon and every second of delay counts significantly. Melvin Webber, one of the authors of the wicked problem, in the 1960’s decried the “non-place urban realm” which he felt was used to legitimize the domination of the automobile over public transportation and the pedestrian.
An expert solves the problem of the turning radius of a transit bus at an urban street intersection at the expense of economic development and other modes of travel. The red lines indicate the location of the curbs as initially designed by the urban design team. The new curbs (in black) represent the engineers proposed solution.
One of the reasons we prioritize the free flow of automobiles is the way that we choose to illustrate the solutions to street design problems. When we design to a “functional classification” or for “level of service” we eliminate consideration for the placemaking qualities of the street. Illustrations like this one are often used to show how the curb radii need to be eased and the landscape medians need to be reduced in extent, and sight lines need to be created at street corners to accommodate the safe travel movements of tractor-trailer freight delivery or public transport. What illustrations like this fail to show is the negative impacts:
- on-street parking is lost that could serve neighborhood retailers;
- development potential and property tax income is lost to required sight lines;
- speeds increase;
- bicycle safety is diminished and biking is discouraged; and
- pedestrian safety is compromised and walking is discouraged.
In February I attended and helped facilitate a training in the Institute of Transportation Engineers (ITE) in Chicago. Most of the participants were experienced engineers that work for Illinois Department of Transportation. All the participants were interested in learning how to apply the new guidelines from the 2010 ITE Manual for Creating Walkable Urban Thoroughfares. One of the case studies was a downtown street in a small city that had been laid out in the 19th Century. Eventually the street under study became one of a pair of the State highway that passed through town. Despite their extensive experience and knowledge, the members of the training class developed solutions for this main street that ignored the role of all other streets in the network. They had trouble remembering that there were other streets that could support the function of the network and that this particular street did not have to provide every function: freight mobility, on-street parking, left-turn access to mid-block surface parking lots, bicycle lanes, and expanded sidewalks. One of the reasons it was possible to ignore the additional capacity that the network does provide was the base maps provided in the training showed only the one street rather than showing a larger context.
“The best transportation plan is a land use plan,” Brent Toderian. “The best land use plan is a transportation plan,” Ian Lockwood. The figure-ground relationship that is the network of streets and fabric of blocks that make up our cities means that both Toderian and Lockwood are kind of wrong in the sense that neither can predominate the other. You can’t have a land use plan without a transportation plan and should that transportation plan ignore its context and fail to adequately support the adjacent land uses it will also fail the society that it is intended to serve. Other than taxi and bus drivers, no one makes money going places. You may save money by saving time when you go places, but wealth is created only in that fabric between the streets where people meet.
The disadvantage of the authoritative approach to solving wicked problems is evident in the sample illustration above. A well-educated, highly-skilled, and licensed engineer’s response to the urban design of an intersection is to discount the needs of pedestrians and bicyclists and ignore the economic potential of land uses while making the turning movements for large vehicles easy, convenient, and safe. The expert is never charged with applying a collaborative approach with the residents, neighbors, and businesses that would accommodate and support other modes of transport. The expert accepts no responsibility for the loss of value or economic development potential for the adjacent land use. These elements have been abstracted out of the problem set, so the solution under the authoritative approach is obvious to the individuals who control the technology and are secure in their expertise.
Challenging solutions like this intersection all too often places other interested parties into the competitive approach to solving wicked problems where the various parties attack one another using their respective set of “experts” to defend their entrenched positions. Eventually a solution that satisfies no one emerges, but most often it is the solution most strongly influenced by whichever expert is in control of the technology that developed and represents the solution.

A Call to Action
Employ a collaborative approach to the identification, redefinition, and solution of the design of the streets in your community. Create a street network that supports communities and places by including and empowering the residents, neighbors, and businesses. Make them equal members of the larger design team. Use them to map the existing network that is their community. Help them identify those qualities that represent the existing strengths of the community, the opportunities for repair and renewal, and the border vacuums that unnecessarily isolate elements of their community and interrupt the network. Work together to illustrate how well the layout of the network influences the social, cultural, economic, and environmental performance of the places in their lives. Give the community access to, and control of, appropriate technology that enables them to communicate their full understanding of the needs of the community.
Model the network first. For much of our recent history we’ve employed those things that have been easy to measure such as, average daily volume of automobile traffic or the level of service of an intersection, as the essential determinants that must be solved in street design. We’ve invested those things that we can easily measure with importance that far outweighs their true value. And we have tended to dismiss those things that are difficult to measure, like the movement of pedestrians, because they have traditionally been difficult or impossible to quantify. As Abraham Maslow said, “if the only tool you have is a hammer, you tend to see every problem as a nail.” Our technology is becoming increasingly capable of measuring and evaluating those determinants that we have been ignoring.

When the collaborative approach is used, all parties will be heard, their stories told, and their contributions incorporated into the solution of the wicked problem. Finding true collaboration, however, often means that the organizer has to surrender some of their authority and power to fully accommodate, involve, and invest the other stakeholders in both the problem and its solution. This can mean giving up control of the technology that is used to represent the symptoms of the wicked problem and its full array of potential solutions. The singular disadvantage of the collaborative approach is that achieving a shared understanding and commitment to solving a wicked problem is a time-consuming process. But the enduring value of a solution achieved through collaboration will represent a much greater value for money over time.

Capitol Hill's Fabulous Streissguth Gardens
For as long as I have lived on the Hill, I have not only enjoyed the many fine views our particular situation presents us, but also the many stairs (or, in Seattle parlance, hill climbs) that dot our landscape, providing even more vantage points to take it all in. Among my Capitol Hill favorites is the Blaine Street hill climb, which is perhaps the longest and best located of them all. Yet, it is not only its length that distinguishes it above its peers, nor its spectacular views. Instead, the Streissguth Gardens, which are adjacent to and south of the hill climb, between 10th Avenue East and Broadway East, raise this hill climb to a must-visit status for all Capitol Hill and Seattle residents.
The idea for this post has been germinating for over two years, originating when I made the hill climb part of my morning run. Admiring it in the predominantly twilight early morning hours, I passed by dozens of times, leaving determined to explore the garden in more favorable lighting and without sleep still in my eyes. Imagine my fantastic luck when the very spring afternoon I set forth on my task, none other than Ann Streissguth was tending her family’s masterwork. Fantastic luck indeed, as Ann graciously and spontaneously led me on what must have been a one and one half hour tour of the garden. The artist’s tour of her life’s great passion and creation proved to be a thoroughly enjoyable and aesthetically pleasing blend of creativity, planning, space, and time.
Developed gradually over the course of more than forty years, the gardens have grown from a tangled and disordered hillside to approximately one acre of ornamental gardens and tamed woodland. The oldest gardens surround the family’s two houses on Broadway East, just north of the East Blaine hill climb. These gardens remain private, but visitors are welcome by appointment. The newer portions of the gardens lie south of the East Blaine stairs and they are now publicly owned and open to visitors year-round.
Throughout the tour, it was a treat to hear not only the Latin names of dozens of plants casually yet authoritatively thrown about, but also to be privy to the story behind each particular plant’s selection, planting, and location. Among the dozens referenced that day, more than one had a deep personal history behind it. The one pictured below came from Ann’s mother’s home in central Oregon, and is some sort of exotic and apparently sturdy flower. If memory serves me correctly, this particular flower may be over half a century old.
Many of Ann’s stories that afternoon centered around the heroics of her son – the indomitable (and evidently charismatic) Benjamin, who either single-handedly or with the assistance of his seemingly inexhaustible legion of friends, has performed much of the actual heavy lifting for the garden, including installation of its sprinkler system, construction of many of its stairs and gabion-basket retaining walls, as well as hoisting a stone bench up the steep hillside in order to provide fabulous views to Lake Union and the Olympics.
Access throughout is provided by a thoughtful system of paths, which deftly navigate the steep hillside and are advantageously placed to afford equally rewarding distant and territorial views. The stroll along the pathways is akin to strolling along a historical timeline, for as one wanders further south, one gradually transitions to the garden’s pre-Streissguth state, entering the northern limits of the St Mark’s greenbelt, with its blackberries, erosion, and detritus indicating that dedicated and enduring stewardship of Ann and her family is required to achieve the results visitors so readily enjoy in the garden proper.
For those desirous of either confirming or enhancing their botanical knowledge, one need not have the benefit of Ann as docent; there are plant identification tags for much of the flora (although Ann noted that visitors often make off with the tags, so do not be disappointed should you leave still wondering just what cultivar of rhododendron so captivated you). Other signage reminds one that care needs to be exercised while enjoying the plantings; and, as one enters from the hill climb, there is a diminutive box that welcomes all with a colorful brochure and trail map, which also includes a list of seasonal highlights.
Ann’s oral history of the garden, from its early conception to its current state, included tales of powerful storms that have shaped the hillside, supportive friends and foundations who have aided in the achieving of the garden’s many splendors. Each event has proved fertile ground for the Streissguth’s creativity, and resulted in new terraces and stairs, or in the case of the tree topping by capricious neighbors, in the preserving of dead trunks in order to provide habitat for woodpeckers.
The planning and design of the garden offers flowers in bloom throughout the year, even though Ann admitted that the March afternoon of our impromptu meeting was perhaps the best time of all to visit. It would be hard to contest her appraisal, with the gentle pastels of green, pink, and white sinking one into another, creating a glowing world of polychrome serenity. The spatial dynamics of the garden are equally compelling as is its palette. The steepness of the hillside (over 50 feet of relief), combined with the varying density and either horizontal or vertical disposition of the planting creates a visual complexity that is extremely satisfying in its layering and shifting combinations.
Regardless the season or time of day, a visit to the garden – or better yet, ongoing visits throughout the year – proves to be a fabulous experience and leaves one with wonder that such variety and beauty can be tucked away in such a compact and seemingly inaccessible hillside. I envy the fortunate neighbors who can avail themselves to the garden’s endless charms on a daily basis.
A brief history of the garden (and website information should you want to volunteer), taken from http://www.streissguthgardens.com/:
In 1962, Dan Streissguth completed building his house on the lot he had purchased north of the Blaine Street stair. He immediately commenced work on the garden surrounding his new home. In 1965 Ann moved into the adjacent house at 1806 Broadway East and began at once working on her hillside garden. The winter of 1968 saw the two gardens combined through Ann and Dan’s marriage. The coupled settled into what had been Dan´s house, leasing out Ann’s house in the years since, while continuing to care for the combined gardens. 1970 welcomed the birth of Ann and Dan’s son, Benjamin.
In 1972 the family purchased the hillside lots south of the Blaine Street stairway and began nurturing them into a cultivated green space. After twenty-four years of growth and development, the family’s 1996 gift of the land to the city led to the garden becoming a public space. That same year, as the Streissguth land was transferred to public ownership, the city purchased (from a third party) the larger hillside tract
abutting the existing garden to the south. The gifted garden and the adjacent heavily-wooded purchased land have become extensions of the city´s existing St. Mark´s Greenbelt. This carried the older 1/4 mile long green space a full city block further north, connecting it to the busily-used public stair right-of-way along East Blaine Street.
Capitol Hill's Modernist Enclave
Tucked away on a narrow, winding street on the north end of Capitol Hill lies an enclave of modernist homes dating from an early 20th Century masterwork to those that aspire and are just completing construction. Some are exemplary, some are rather ordinary, but their grouping on the same compact hillside of Capitol Hill compounds their inherent charms and attraction.
East Boston Terrace escaped my notice for years before its very existence was pointed out to me by another aficionado of modern design. At the panoramic viewpoint where East Boston Street dies into 15th Avenue East, Boston Street’s continuation could easily be confused with a driveway. The street quickly dives into the hillside, disappearing from view, with its steep slope leading one to a protected and sheltering environment.
Coming from the south along 15th Avenue, the first hint of this micro-neighborhood’s presence is the rather long, moss covered stair that takes you from the 15th/Boston bend down to Boston Street itself.Once down the stair, one is greeted by the newest addition to the mod-enclave, a tasty red and tan home, whose materials, massing, and color make it very au courant. Still under construction the chilly January morning I did my most recent walk, the building’s rather austere front elevation is in contrast, I imagine, to a fully glazed one opposite, and intended to capture what must be spectacular views to the east.
Next up on the tour of modernist boxes (and I use that term in the most affectionate way), is a little grey number that I would guess is of late 1970’s or early 1980’s vintage. The tightly spaced vertical siding and the glass canopy at the entry are amongst the clues. To the right you will notice the ‘outie’ balcony; a classic modernist move. One also may notice that the car port is actually a bridge, a hint of further hillside gymnastics to come.
Skipping over the next building (saving the best for last), a Frank Lloyd Wright-inspired, prairie-styled dwelling commands the fork in the road. A beautifully tended landscape is fitting for a home so sited and inspired. The hip roofs and stone base help the home blend into its surroundings, much in the manner Mr. Wright preached it ought to.
E. Boston Terrace’s relative seclusion reveals itself the further one progresses into its realm, with the closest neighbors looming above, their yards forming an effective demarcation from the rest of Capitol Hill. Spatially, this juxtaposition of higher and lower elevation homes in a compact space is reinforced by the homes not being aligned on the grid one typically finds in our neighborhood. Seen here in the foreground are two less obvious modernist homes. A little closer up, the rambler may appear more suburban than not, but I cannot help but speculate that when constructed, such a distilled domestic image was certainly at odds with the craftsman bungalows that filled Seattle, making this home a trend setter for its time. A subtle move to be sure, but the way the home allies itself with the curve of the street hints at its less-than-traditional posture.
The hillside situation of Boston Terrace not only produces interesting visuals on the uphill side, but as you can imagine, on the downhill side as well. On this particular morning, I was fortunate enough to catch a view of the Cascades in all its winter splendor.
Backing this spectacular view is a more recent contemporary home. While it’s difficult to discern its exact vintage, the split face concrete block at the base hints at the 1990’s. That presumption is partially undermined by the apparently steel-sashed windows which typically hint at a much older home. Kudos to both architect and owner for seeing the value in installing such gossamer windows – their delicacy and transparency come at a premium price – but, with the view they engage it was clearly worth it. Another nice modernist touch is the simple and highly ordered landscape, comprised of uniform and geometrically deployed trees set in a carefully manicured ground cover.
The infrastructure enthusiast in me is impressed by the extent to which bridges and roads are engineered to provide access to these otherwise inhospitable locales. I could not help but be impressed by the determination to build a road on this hillside. Have a look at the pilings supporting the roadway/bridge in front of the home just discussed.
Now for la pièce de résistance and the true inspiration for this post -- a great white box that sits across from the above-mentioned prairie style home. The term modernist gets thrown around a lot, including by me. Despite this etymological transgression, there is an image that I and many others hold as truly modernist -- that of the early 20th Century, European-based, International Style pioneered by architects such as Walter Gropius. Although by no means ignored in the United States, it never quite captivated the imagination as it did across the Atlantic. To be sure, later American designers took such inspiration and molded it as their own, as shown by the designs of such masters as Eero Saarinen and Craig Ellwood. These later accomplishments aside, the pure white box antecedent was rare in the US, and rarer still in the Northwest (as opposed to California, the upper Midwest, and the Northeast). However, we do have at least this one on the Hill, and it is such an outstanding example it almost makes up for the dearth of others.
From the looks of it, this home falls squarely in the 1930’s, and my guess is the work of Paul Thiry, one of Seattle’s legendary architects whose oeuvre includes Key Arena and much of the related planning for the 1962 World’s Fair. Not that authorship matters here, as regardless of designer, it is exemplary of its type and a real treasure. Based upon previous strolls on Boston Terrace, it appears to have had some recent restoration work performed, and is sporting at least a fresh coat of paint and restored (or at least tidied-up) steel windows.
The house itself has all the modernist cues: cubic form, bone white paint, steel corner windows, entry canopy, and assertive chimney. How I dream of more such beauties to be on the Hill -- even the perennially abused glass block is perfectly incorporated into the design! Greater than the sum of its parts, this house also displays a deft hand at proportion, scale, and overall execution that makes it among the Hill’s finest looking residences, all reason enough to take a stroll into Capitol Hill’s modernist enclave and witness is beauty first hand.
