Common Ground is a 2025 conversation about why a sidewalk is never just pavement. Felipe Correa, Uros Novakovic and Peter Sealy argue that its character is produced by surrounding buildings, street rules, climate, access, and everyday patterns of use. Their central answer is that designing a sidewalk means shaping the larger civic relationships around it.
The discussion first appeared in Architecture Writing Workshop’s August 2025 Sidewalk Issue and was republished by Azure Magazine on September 1, 2025. It is an exchange of architectural ideas, not a statistical study or a design standard, so its historical accounts and predictions belong to the speakers and should be read as arguments.

The conversation’s direct claim is that a sidewalk is a civic system, not an isolated strip of paving. Felipe Correa, Uros Novakovic and Peter Sealy describe walking space as the result of several forces acting together: the street’s legal and physical arrangement, the buildings and thresholds beside it, the people allowed to use nearby spaces, local climate, and the political choices that allocate public rights of way.
Correa puts the point starkly: “They’re always defined by something else: by the adjacencies that surround them, by the political climate that structures a particular kind of open space—or the lack of public space altogether.” The statement appears in the original Architecture Writing Workshop interview, where the participants repeatedly return to the idea that an apparent edge condition is actually a record of larger decisions.

That framing changes the practical question. Instead of asking only how wide, smooth or attractive a sidewalk should be, a designer must ask what neighboring doors, setbacks, retail fronts, transit stops, shade, crossings and rules are doing to public life. A technically generous pavement can feel hostile if its edges are blank or controlled; a modest path can become socially important when it connects active thresholds and welcomes different kinds of users.
How does the conversation define a sidewalk’s relationship to the street?
The speakers treat “sidewalk” as a variable condition rather than a universal object. In some places, walking is confined to a raised or legally defined band beside moving traffic. In others, pedestrians share the carriageway, occupy plazas, or move through a sequence of public and privately managed edges. The boundary between street and sidewalk therefore reflects a city’s regulations and habits as much as its paving detail.

If every public activity is assigned to a narrow residual strip, the street is treated as traffic infrastructure and the sidewalk as leftover circulation. Conversely, when the whole right of way is understood as civic space, crossings, loading areas, curb zones and building thresholds become part of the pedestrian experience rather than exceptions to it.
Novakovic describes the result as “a negotiated space, not just in terms of geometry, but through presence.” People negotiate by slowing, passing, waiting, watching, talking, displaying goods, making room for mobility devices or deciding whether a threshold feels open. Those negotiations are not flaws to be eliminated; they are evidence that the sidewalk is shared.
Why does walking matter to public life?
For Sealy, walking is a way of knowing a city. “My way of exploring a city is always by walking it,” he says. The sentence is personal rather than a measured research finding, but it captures the interview’s larger concern: street-level movement exposes relationships that a plan or aerial view can hide.
At walking speed, people encounter one another without having arranged the meeting. They become visible to strangers, observe how others occupy space, and adjust their behavior in response. The interview associates this ordinary visibility with a shared civic life: not constant agreement, but the ability to coexist, disagree and remain part of the same public scene.
That public encounter is different from a programmed event. A sidewalk can support a parade or a market, but its civic value also lies in unplanned moments—waiting beside someone, noticing a neighbor, seeing a demonstration, or simply sharing a route with people whose lives do not otherwise overlap. The participants do not claim that every encounter is positive or safe. They ask instead what kinds of uncertainty a city is willing to accept in exchange for a genuinely public realm.

Is ambiguity a strength or a weakness in sidewalk design?
The conversation treats ambiguity as both. Unclear edges can make a place difficult to navigate, expose people to conflict, or conceal who has authority. But a completely scripted environment can remove the possibility of appropriation and encounter that makes public space meaningful.
Novakovic’s idea of negotiation helps explain the balance. Geometry still matters: a path must be passable, crossings legible and conflicts managed. Yet no drawing can predetermine every social use. A sidewalk becomes common ground when its physical and institutional framework allows different people to appear, pause and move without requiring a private invitation.
For designers, that means distinguishing productive flexibility from neglect. A flexible edge might support a bench, a vendor, a planted buffer or a temporary gathering while keeping routes clear. Neglect is different: broken paving, inaccessible entrances or arbitrary barriers shift the burden of negotiation onto the people least able to absorb it. The interview does not offer a universal dimension or detail; it asks readers to examine what their local rules and adjacent buildings make possible.
What do Minneapolis skyways and Houston tunnels reveal about climate?
The speakers use Minneapolis’s downtown skyways and Houston’s tunnel network as examples of climate-related alternatives to exposed street-level walking. Sheltered routes can make movement more comfortable in severe cold, heat or rain. They can also redirect activity away from the sidewalk, changing which spaces receive eyes, entrances, commerce and chance encounters.
The point is not that skyways or tunnels are inherently bad, nor that every city should reject them. The interview asks what is gained and what is displaced when a network becomes internal or elevated. A route may be physically accessible yet socially selective if it depends on connected buildings, particular opening hours or controlled entrances. Street-level space remains the part of the city that can be encountered without entering a specific institution.
Because the conversation does not compare current access rules, costs or outcomes in either city, its examples should be read as questions rather than policy verdicts. They prompt a useful review of any climate adaptation: Does it supplement the public sidewalk or replace it? Who can enter? At what times? What happens to the people, shops and informal activities left outside?
Are streets and sidewalks losing their civic identity even when they remain public?
The interview distinguishes between publicness and civic identity. Correa states, “As for the distinction, publicness refers to accessibility—the fact that a space is open to everyone.” A space can meet that threshold and still fail to express collective investment or pride.

Civic identity, in Correa’s account, concerns whether people recognize a place as part of a shared life and feel motivated to care for it. The distinction helps explain why a privately managed plaza may permit broad access yet communicate a narrow image of who belongs, while an ordinary municipal street can carry strong civic meaning through everyday use and stewardship.
Correa discusses Hudson Yards and Rockefeller Center as contrasting examples for thinking about this difference. The interview does not provide a comparative policy study of either development. Its analytical use is to separate two questions that are often collapsed: Is entry technically open, and does the space invite public pride, participation and responsibility?
The participants also question whether internal building networks, privatized open spaces and digital life are drawing attention away from shared streets. They present this as a concern and interpretation, not a settled measurement of social decline. The useful response is to examine the specific rules, thresholds and investments that shape a place rather than assume that “public” on a plan guarantees a public experience.
What degree of risk are people willing to accept in public?
Public space cannot remove all uncertainty. A city can improve lighting, crossings, maintenance and access, but it cannot guarantee that every encounter will be comfortable or predictable. The conversation asks how much risk a community is prepared to tolerate in order to retain openness and spontaneous interaction.

This is a political question as much as a design question. Novakovic says, “The real issue is political.” Decisions about surveillance, policing, event rules, seating, vending, deliveries and private security determine whose presence is treated as normal. A polished surface does not settle those questions.
A responsible approach is to name the trade-offs. A barrier may protect a loading zone but block a wheelchair user. A controlled entrance may provide shelter but exclude people outside business hours. A highly predictable route may reduce conflict while making lingering impossible. The interview’s value lies in keeping these choices visible instead of presenting them as neutral technical fixes.
How should autonomous vehicles influence the future street?
The speakers argue that cities should decide the civic landscape they want before allowing autonomous-vehicle technology to reorganize streets by default. Their position is normative: it is a proposal for public choice, not a verified forecast of when or how autonomous vehicles will arrive.

Applied to sidewalk planning, the principle is straightforward. Begin with goals for walking, gathering, access, deliveries, shade, safety and public identity. Then ask how automated vehicles might be accommodated without surrendering the right of way to a single mobility system. Possible questions include whether curb space remains available for people, how crossings are protected, and whether vehicle efficiency is being purchased at the cost of street-level life.

The interview’s warning is against technological inevitability. A city that waits for a platform or fleet to dictate the street may discover that civic choices have already been made through lane allocation, sensor infrastructure and restricted access. Setting priorities openly allows residents to debate the trade-offs before they become embedded.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What happens when we actually design a sidewalk?
The conversation suggests a design process that starts beyond the pavement drawing. A sidewalk project should map the systems and edges that will determine how the space works.
- Read the surrounding network. Identify street classifications, crossings, transit, curb uses, building entrances, service routes and privately controlled passages. Treat these as one field rather than separate departments.
- Identify who can use each route. Record physical access, opening hours, fees, security controls and informal exclusions. Distinguish a route that is legally public from one that is practically available.
- Observe patterns without treating them as permanent. Note where people wait, meet, sell, rest, avoid or cross. These observations describe current negotiations; they do not prove that a use should remain unchanged.
- Design the edges as carefully as the walking surface. Entrances, setbacks, shade, seating, planting, lighting and ground-floor activity determine whether the path feels connected to civic life.
- Test climate strategies against street-level consequences. If a skyway, tunnel or enclosed connection is proposed, ask what it supplements, who can enter and what happens outside.
- Set civic goals before adding technology. Define the public outcomes a street must protect, then evaluate autonomous vehicles or other systems against those goals.
- Plan for negotiation and maintenance. Make room for legitimate variation while specifying who resolves conflicts, repairs damage and revisits rules as conditions change.
None of these steps replaces local standards, accessibility requirements or engineering. They broaden the brief so that compliance is not mistaken for civic success.

How should readers use the interview?
Common Ground is most useful as a set of questions to carry into a site visit or design review. It does not provide sidewalk widths, safety statistics, access regulations or an autonomous-vehicle timetable. Those require jurisdiction-specific evidence and current technical guidance.

When a sidewalk feels empty, ask what its edges and rules are doing. When an internal climate-controlled route appears successful, ask who is missing from the street. When a new mobility technology promises efficiency, ask which civic purposes remain non-negotiable. The sidewalk, in this account, is where those larger choices become visible in everyday life.
Frequently Asked Questions
Where was “Common Ground” first published?
The interview first appeared in Architecture Writing Workshop’s August 2025 Sidewalk Issue. Editors Mai Okimoto and Sebastián López Cardozo conducted the discussion; Azure Magazine later republished it on September 1, 2025.
What books are connected to the autonomous-vehicle discussion?
The conversation cites Evan Shieh’s Autonomous Urbanism while considering how cities might define a civic landscape before autonomous vehicles reshape streets. The source establishes the title’s relevance but does not verify a current edition or availability.
Is “Common Ground” a study of sidewalk safety or access?
No. It is an ideas-focused architectural conversation. It raises questions about access, publicness, climate-controlled routes and risk, but it supplies no statistics or policy comparison, so readers need local standards and independent evidence for implementation decisions.
Why does the interview separate publicness from civic identity?
Publicness asks whether everyone can access a space. Civic identity asks whether that space is experienced as a shared achievement worthy of public pride and care; the two qualities can appear together, but one does not guarantee the other.
