When the Sidewalks Go Quiet

I have a particular vantage point from which I have begun to think differently about downtown Petaluma.
Every Saturday morning—52 weeks a year, rain or shine, except when I'm away—I have breakfast at Della Fattoria Cafe & Bakery on Petaluma Boulevard when it opens at 8:00 am. I have been doing this for years. My friendship with the late Kathleen Weber, the renowned bread baker who created Della Fattoria, and my role as godfather to her children, Aaron and Elisa Weber, have made Della Fattoria much more than a place where I eat breakfast. I have a dedicated Saturday morning seat.
From that seat, I watch the place come alive.
I see the opening preparations, the wholesale bread trucks returning from their morning deliveries, the bakers and café staff getting ready for the day, the first customers arriving, friends greeting one another, people stopping for coffee and bread, and the steady gathering of the Saturday morning crowd. There is a ballet inside the café—and another one unfolding outside it on Petaluma Boulevard.
And because I sometimes linger well into the afternoon, I also watch that ballet outside change.
The morning has a strong pulse. Then, gradually, something happens. As morning gives way to midday, the pulse becomes less intense. By afternoon, there are periods when the sidewalk becomes surprisingly quiet.
Petaluma Boulevard itself, of course, hasn't become quiet. Cars continue moving north and south. In Charles Marohn's terminology, Petaluma Boulevard functions in important respects more like a stroad than a traditional downtown street—it continues to perform the job of moving traffic as fast as possible through the stop lights and the city center.
But the sidewalks are doing something else. Or, increasingly, they aren't.
That observation has made me think about a claim I hear fairly often: “downtown Petaluma is thriving”.
I understand why people say it. Downtown has attractive buildings, busy restaurants, successful businesses, visitors, events, and periods when the streets genuinely feel alive. But I also hear something different from merchants. Many describe themselves as surviving rather than thriving.
I've begun to wonder whether both observations might be true.
Perhaps the problem is that we are looking at downtown at different moments—or perhaps that we are using different measures of what it means for a downtown to thrive.
The daily pulse
Jane Jacobs gives us a useful way of thinking about this. In The Death and Life of Great American Cities, Jacobs described the remarkable vitality that can emerge when different people use the same urban spaces for different purposes at different times of day. She famously called the resulting interaction a “sidewalk ballet.”
The metaphor is a good one. A ballet doesn't consist of everyone doing the same thing at the same time all of the time. Different dancers enter and leave. Different movements overlap. One movement sets up the next. The result is something more than the sum of the individual dancers.
Cities work in much the same way.
A downtown has what we might call a daily pulse. Morning activity gives way to midday activity; midday to afternoon; afternoon to evening, evening to night time. The intensity naturally rises and falls. A city doesn't need to be equally busy at every hour. In fact, it shouldn't be, and probably can’t be.
But there is an important difference between a pulse that rises and falls and one that simply fades.
What I have watched from my Saturday table, week after week, is a downtown pulse that seems strongest in the morning. By midday it is less intense. By afternoon it can be weaker still. And when evening arrives, activity returns, but in a much narrower form.
This isn't an argument that downtown is dead. Far from it. It is an observation about what kind of activity is occurring, when it occurs, and what happens when one activity ends.
Della Fattoria is an interesting example. Its morning and early-afternoon activity demonstrates that people will come downtown and spend time there. Yet the café cannot sustain dinner service, nor can it remain open seven days a week.
That doesn't mean Della Fattoria is unsuccessful. Quite the opposite.
But it does raise a larger question: What happens to activity on Petaluma Boulevard between Washington Street and Western Avenue when Della Fattoria's activity winds down?
Does another wave of people arrive for another purpose? Does something else take over?
This is where Jacobs's idea of succeeding activities becomes important. A thriving downtown isn't necessarily one in which every business is busy all day. It is one in which the activity of one part of the day gives way to another, with different people entering the scene as others leave.
The morning café crowd need not become the afternoon shopping crowd. The people who come downtown for lunch need not be the people who arrive for an afternoon event. Families may appear after school while office workers are heading home. People who come downtown for dinner may be joined later by people coming specifically for a performance or gathering.
What matters is not that the same people move through a predetermined sequence of activities. It is that the cast keeps changing while the stage remains alive.
The dancers enter and leave. New dancers replace them. Different activities overlap. One use may be winding down just as another is beginning.
The continuity comes not from the people themselves but from the ongoing presence of different people engaged in different activities for different reasons.
That is the sidewalk ballet. And that is why diversity matters.
But Jacobs's diversity is about more than having different things in the same place. The deeper value of diversity lies in the relationships those differences make possible. The baker, the merchant, the artist, the office worker, the resident, the visitor, and the child are not simply occupying the same downtown. They belong to different networks of activity, interest, knowledge, and relationship—and the city brings those networks into physical proximity.
A downtown can be busy for a few hours because a particular activity attracts a particular crowd. But a genuinely vital downtown has enough different uses, people, and purposes that the public realm keeps being repopulated as the day progresses.
This becomes particularly interesting after dark.
By evening, many of the daytime commercial uses have closed. What remains open is disproportionately restaurants and bars. There is nothing wrong with either. Restaurants are an essential part of a healthy downtown, and bars can contribute to urban life.
But if most of the evening economy consists of eating and drinking, then the range of reasons for being downtown has narrowed considerably.
A downtown can therefore be busy without being particularly diverse in its uses.
I had a more visceral experience of this just a month or so ago.
The Vacancy Project team from Petaluma Urban Chat had joined Renaissance Petaluma for an opening event that ran from 6:00 to 7:30 pm. There had been people in the building, conversation, activity—the ordinary energy of a gathering. After helping close things down, I walked up Petaluma Boulevard, crossed Washington Street, and cut through Penry Park to where I had parked on Kentucky at the northwest corner of the Park.
And something happened along the way that I haven't quite forgotten.
As I walked up the Boulevard, I encountered virtually no one. As I cut through the Park, I noticed one person sitting on a bench, speaking loudly to himself. Otherwise, there was no one.
The farther I walked, the more uneasy I became.
I hesitate to call it fear because nothing actually happened. No one threatened me. There was no obvious danger. But I became increasingly conscious that I was alone in what was supposed to be the heart of a city.
That experience brought home something I had been thinking about more abstractly.
A downtown does not feel like a city simply because there are buildings, businesses, and streets. It feels like a city when there are other people in it.
There is a substantial body of urban thinking about the relationship between human presence, density, activity, and our perception of safety and comfort in public space. Empty spaces can produce a very different psychological response from active ones. The absence of people can make us more alert, more uncertain, and sometimes more fearful—even when there is no specific threat.
I had just come from a gathering filled with people. Twenty minutes later, I was walking through the same downtown and felt almost completely alone.
That contrast made the idea of the daily pulse much more tangible to me. It isn't just about economic activity. It is about how a city feels when its pulse weakens.
And that returns us to Jacobs. She wasn't describing a place where everyone gathers for the same purpose. She was describing the interaction of different people engaged in different activities, often without even intending to interact.
This suggests that urban vitality is not simply a function of how many people or activities are present. It is also a function of how many possible connections exist among them. A city can be physically dense without being socially connected; it can contain many different uses without those uses meaningfully intersecting. What gives density its urban power is the possibility that different people, activities, and networks will encounter one another.
The question for Petaluma isn't simply whether there are enough people downtown at 8:00 pm on a Wednesday night. It is whether there are enough different reasons to be downtown throughout the evening—and throughout the day.
The stage isn't enough
At this point it is tempting to make a list of the kinds of uses that might quicken the pulse:
A performance space.
An evening class.
A farmers market.
Children's activities.
More cultural programming.
More places to gather.
All of these may be good ideas. But perhaps they aren't really the point.
The existence of a public space doesn't by itself produce urban life. We all know places that are beautifully designed, carefully landscaped, and largely empty because there aren't enough people or enough reasons for people to be there.
My walk that night through Penry Park is a good example. It was a public space. It simply wasn't an urban stage. There were almost no people around it.
Jacobs' sidewalk ballet depends upon something more fundamental: urbanity. It depends upon the density and diversity of uses and users in close proximity. People living nearby. People working nearby. Businesses opening and closing at different times. Places to eat, shop, gather, perform, learn, work, play, and simply be. Residents and visitors. Children and adults. People with destinations and people without them. Uses that overlap and users who continually replace one another.
But proximity alone is not enough. What matters is the possibility of intersection. The value of a person, business, institution, or place within the urban network is partly a function of how many other networks it can connect. A bakery is a business, but it can also be a neighborhood gathering place, a workplace, a destination, a meeting point, and a link between people who might otherwise have little reason to encounter one another.
It is this concentration of different people and activities—not simply the existence of public space—that creates the possibility of the ballet.
Urbanity is the stage.
And that changes what we should mean when we say that the city should “create the conditions” for the ballet.
It doesn't mean putting a plaza or a park wherever there happens to be available land and hoping activity will appear.
It means cultivating the density, diversity, proximity, connectivity, and flexibility from which urban life can emerge and sustain itself.
That is one reason downtown matters.
Downtown already possesses something that an isolated public space cannot easily manufacture: proximity. Different uses and different populations are compressed into a relatively small area. The opportunity is to strengthen those relationships—to make it easier for one activity, one destination, and one group of people to encounter another.
And this is where Jacobs's argument reaches beyond the question of whether downtown looks or feels lively. A great city is not simply a collection of active places. It is a network capable of continuously renewing itself. People arrive and enter existing networks. Businesses open, close, and change. Buildings acquire new uses. Institutions form new relationships. Old places provide opportunities for new enterprises. The city remains alive because its existing relationships continually create the possibility of new ones.
This brings me to a question that may be more important than asking what downtown should contain.
What kind of civic environment allows a diversity of activities to emerge in the first place?
The city's job may not be to choose the ballet or be the choreographer. Its job may be to create the conditions in which a ballet can emerge. That is a different kind of civic responsibility.
It means thinking less about prescribing the outcome and more about creating the conditions for experimentation, adaptation, and discovery.
It means creating a downtown in which small businesses can find a foothold, where public spaces are embedded in rather than isolated from concentrations of activity, where people can gather without having to make a purchase, where regulations don't unnecessarily suppress small or unconventional activities, where buildings and spaces can evolve, and where enough people live and work nearby to provide the audience, participants, customers, and serendipitous encounters that make urban life possible.
Cities are remarkably good at producing unexpected combinations when the conditions are right.
People open businesses we didn't anticipate. Artists find spaces we didn't know they needed. Community groups invent events. Entrepreneurs experiment with new uses. Children appropriate public spaces. Residents create informal social networks. One successful activity creates an opportunity for another.
This is why a great city cannot be understood as a finished arrangement. Its vitality comes from the continuing interaction of its networks—the unexpected connections among people and activities that no planner could fully specify in advance.
If the goal isn't to move the same people through a prescribed sequence, then the city cannot really choreograph the ballet.
The continuity is in the place, not the individual dancers.
The city can create the conditions in which different dancers, arriving for different reasons, keep finding a stage on which to participate.
Putnam Plaza as part of the stage
This is one reason I am interested in the renewed attention being given to Putnam Plaza on Petaluma Boulevard.
Its potential isn't simply that it could be programmed with activities. Its greater value may be that it sits within the urban concentration of downtown.
A dense farmers market could create a strong morning or midday pulse. Small performances could extend activity into the afternoon or early evening. Children's activities, demonstrations, exhibitions, public conversations, community gatherings, seasonal celebrations, pop-up markets, outdoor classes, and other informal events could give people reasons to come downtown that have nothing to do with shopping or eating. And something nobody has thought of yet could emerge.
That last possibility may be the most important. A public space can provide a place for activities that are too small, temporary, experimental, seasonal, or community-oriented to justify a storefront. But the space becomes much more useful when it is embedded in urbanity—when people are already nearby and other activities are already occurring around it.
Putnam Plaza doesn't have to be the whole stage. It can be one part of a larger stage.
The ballet may be bigger than downtown
The same thought makes me look differently at the renewed interest in reimagining the River Trestle.
We tend to think about downtown, the Theater District, and the Warehouse District as separate areas. But perhaps their greatest potential lies in how they might reinforce one another.
Imagine a performance in the Theater District leading people downtown for dinner.
A farmers market or gathering at Putnam Plaza drawing people toward the river.
An event in the Warehouse District giving people a reason to cross the Trestle and continue into downtown.
Dinner leading to a performance.
A performance leading to a walk along the river.
A downtown gathering becoming part of a larger evening rather than the endpoint of a trip.
Now the sidewalk ballet becomes something larger: a district ballet.
The Trestle isn't simply a connection between two points. It can help connect different concentrations of activity, allowing one part of Petaluma to reinforce another.
Its greatest contribution may not be any particular destination on either side. It may be the possibilities it creates between them.
The opportunity is to think of these places not as competing destinations but as parts of a connected urban ecosystem. Putnam Plaza can provide a flexible civic and social space within the density of downtown. The Theater District can generate cultural and performance activity. The Warehouse District can provide additional destinations and forms of creative and commercial activity. The Trestle can make it easier for the people and activities of one area to encounter those of another.
The city doesn't have to decide exactly what happens.
It needs to make more things possible—and make it easier for them to happen together.
From surviving to thriving
Perhaps this is the distinction between surviving and thriving.
A business can survive by capturing enough customers during the hours when its particular market is available. A downtown can survive in much the same way: a collection of businesses can each find their niches, and the downtown can have periods of considerable activity.
But a thriving downtown does something more.
It generates possibilities.
It does so because the city is not simply a collection of nodes. It is a network of networks, and the vitality of that network depends upon the density of its connections and the number of ways those connections can cross from one network into another. The more porous those networks are, the greater the possibility that an encounter in one part of urban life will generate something unexpected somewhere else.
It creates enough density, diversity, proximity, and connection that the activity of one part of the day can give way to another. Its pulse rises and falls, but it doesn't simply diminish. It changes.
And importantly, the people change with it.
The morning crowd leaves. Another group arrives. Workers give way to shoppers. Shoppers give way to diners. Residents emerge. Visitors arrive. Children play. Someone attends a performance. Someone else simply walks through. Some people come with a purpose; others encounter something they hadn't planned on.
No one has to direct all of this. In fact, trying to direct it too closely may defeat the purpose.
The city's job is not to decide in advance exactly what downtown should become. It is to ask whether we are creating the civic, physical, economic, and regulatory conditions in which Petaluma's own creativity can continually produce new combinations of uses and users.
The city shouldn't choose the ballet. It shouldn't be the choreographer. But neither should it simply build a stage and walk away.
It should cultivate the urbanity that makes the stage come alive.
I don't know whether downtown Petaluma is thriving. I suspect the answer depends on what we mean by thriving.
But after watching the morning ballet inside and outside Della Fattoria for so many years—and after experiencing how different downtown can feel when that human presence disappears in the evening—I have become convinced that the question is worth asking.
What would it take for the morning pulse to hand itself off to the afternoon?
What would allow the afternoon to generate an evening that is about more than eating and drinking?
What would make it possible for downtown, the Theater District, and the Warehouse District to reinforce one another rather than function as separate destinations?
And, most importantly, what kind of city would allow us not to know the answers in advance?
Maybe a thriving downtown isn't one that is always busy.
Maybe it is one in which the density and diversity of urban life are sufficient to keep producing new reasons for people to be there.
Maybe it is one in which the networks of urban life remain sufficiently dense, diverse, and porous that new relationships can continually emerge.
Maybe it is one that has the conditions to keep coming alive.
And perhaps that is what Jacobs was seeing beneath the sidewalk ballet: not simply activity, but a city continually making new connections among the people, places, and activities that constitute it.
And perhaps that is the sidewalk ballet we should be trying to enable.
