TPS Ep. 4, Visualizing Change

,

The fourth episode in Town Planning Stuff Everyone Needs to Know is about before-and-after thinking. To do planning and urban design you have to take a hard look at a place to see what’s there, and then imagine in your mind’s eye what it should be, in the future. And then, you have to draw it, somehow, and show it to others, and ask, “Is this what you envision, too?”

This is a visual process, it’s not just planning by the numbers. You have to make your visions visual to really communicate them. Advertisers have long known this; they love to depict the new and improved as compared to the old. Think of the TV commercials showing the dirty t-shirt “before” it’s washed in the new detergent, and how great it looks “after” their product gets used or their advice gets followed! Professionals and policymakers have long needed to apply that kind of communication more often to the big decisions about our built environment.

Historically, some of the most influential thinkers about design understood this well. Landscape architect Humphrey Repton painted garden scenes on two layers of canvas, gluing a hinged top layer depicting “before” conditions over a bottom layer depicting his proposal, so he could show the impact of changes with the turn of a canvas flap. John Nolen, the first American to refer to himself as a professional city planner, titled his book “New Towns for Old,” capturing the before-and-after essence of his visions.

Way back in the 1980s, Joe Kohl, Erick Valle and I saw a TV news report about surgeons who were using crude video imagery to show trauma patients how their faces might look after reconstructive surgery. Before, and After. We thought, what if we could do the same thing to help heal the disfigured American city? That few seconds of television changed the course of our lives. We launched our “Image Network” company— the outfit that over time became our town planning practice— with an emphasis on visualization. We got pretty good at it. Those early contracts to produce electronic simulations and communication tools thrust us in front of the whole range of influencers who really decide what happens in our designed environment, from mayors, planners, architects, developers, and engineers, to preservationists, environmental advocates, economists, housing experts, retail experts, and community activists. We quickly got exposed to how all these folks think, and had to learn to translate among them.

But in those first years we gradually realized, and had to confront, a few key things. One was that most decisionmakers, including architectural designers, are terribly unskilled at envisioning how their abstract plans and elevations will actually turn out once built in the real world, such as how big or small the buildings would be, how the streets would feel, and how their new construction fits (or doesn’t) with its context. Another finding: Once we created effective simulations that showed their projects in the cold light of day, warts and all, they often weren’t sure what to do about it to fix the flaws. We felt the need to transition to leading the design and planning process, rather than just reacting to it as illustrators, after all the big decisions had already been made by someone else. Influential teachers like Elizabeth Plater-Zyberk, Mark Schimmenti, Geoff Ferrell and Jaime Correa taught us about urbanism, and we set out to rebuild our practice around the principles they introduced into our studio.

Today, whenever we propose changes to a street scene or a neighborhood, we use drawings and computer imagery to show how the place you know could be transformed over time, new and improved into a better place. We urge planners to think of plans less like a static map and more like a movie, which changes as you go along. It’s about thinking through change over time, whether the changes are gradual or dramatic and disruptive. This helps community leaders and investors make better choices.
