Citizens at the Heart of the City

How LDTs transform participation

Urban planning shapes every street, park, and neighbourhood. But too often, citizens hear about decisions after they have already been made. Local Digital Twins can contribute to changing that - making participation more transparent, more accessible, and genuinely more meaningful.

Yet technology alone is not enough. The real question is: how much influence do citizens actually have? A neighbourhood survey, a participation festival, a planning workshop, a citizen forum, a hackathon - each format serves a different goal and reaches a different audience. Choosing between them is not just a logistical decision. It is a political one.

This is where Sherry R. Arnstein's Ladder of Citizen Participation (1969) becomes an invaluable concept. It describes a spectrum of engagement - from simply informing people at the bottom, all the way to genuine citizen control at the top. The ladder is not just a theoretical model. It is a practical self-check: Where on the ladder does your chosen format actually sit? Are you genuinely sharing power - or creating the appearance of participation without the substance?

Used honestly, the ladder helps planners and administrations align their methods with their intentions. And when an LDT is brought into the process, it can support meaningful engagement at every level - from an interactive map that makes a survey tangible, to a hackathon where citizens co-create solutions using real city data. The key is to be intentional. Define your goal clearly. Choose the format that fits your community. Use the LDT not as a technological showpiece, but as a genuine tool for transparency and co-creation.

The microlearning units in module “citizen participation” from the EID framework, developed by K8 as innovation support partner, are designed to support you in exactly this task: making confident and informed decisions about the right format for the right purpose with your LDT. 

Why real Participation matters - and why this is hard to do

Urban planning should serve the people who live in a city. That sounds obvious. Yet in practice, involving citizens in meaningful ways is surprisingly difficult.

Administrations want to engage the public. But questions arise quickly: Who should we reach? How do we communicate complex planning decisions? How do we ensure that participation actually contributes to outcomes - and is not just a box-ticking exercise?

Sherry R. Arnstein described this challenge as early as 1969, in her famous Ladder of Citizen Participation. She showed that "participation" can mean very different things,  from simply informing people close to the bottom of the ladder, all the way to handing real decision-making power to citizens at the top. Everything below a certain level risks being tokenistic or even manipulative.

An example of how cities try to deal with these challenges, is Utrecht, with its ‘Samen Stad Maken’ approach (Making the City Together). While recognizing that informing or gauging opinions sometimes fits the specific case, the city is trying to further move away from top-down decision-making and instead collaborate more with residents. For example, people are encouraged to start their own initiatives, while the municipality supports them and positions itself in this way more as a partner or facilitator. A compass was developed for civil servants to navigate different forms of participation that fit certain urban issues. The methodology is published on Utrecht's website (in Dutch). 

LDTs can support participation across the entire ladder, or spectrum. And the right format makes all the difference.

Start Small - even one click counts

Not every participation process needs to be a large-scale event. Sometimes, the first step is simply to inform and ask.

An online survey is one of the most accessible formats. Citizens can be reached via social media, local newspapers, or public displays. They respond at their own pace, from wherever they are. When linked to an LDT, the survey becomes even more powerful: instead of answering abstract questions, residents can drop comments directly onto an interactive map - pinpointing exactly which corner of their neighbourhood they are talking about.

This approach works at scale. It is easy to analyse. And can lower the barrier to participation enormously, especially for people with limited time.

On Arnstein's ladder, this format sits at the Informing and Consultation level. This is a starting point - not an endpoint.

Going Deeper - Dialogue and Co-Development

Once a basic channel is established, the conversation can deepen.

Information events with discussion bring citizens and planners face to face. The LDT serves as a visual tool during the presentation: it makes complex planning scenarios tangible and easy to understand. After the presentation, questions and opinions can be collected. Information still flows mostly in one direction, but dialogue begins.

Citizen office hours go a step further. In one-on-one sessions, individual concerns get real attention. If the planner is trained to use the LDT during the conversation, citizens can see, in real time, how their idea might look in the neighbourhood. This is consultation - and it builds trust, but it is quite time consuming and hardly any government agency has the resources to seriously implement something like that.

Planning workshops are where things get genuinely collaborative. Citizens and experts work side by side. Scenarios are simulated and adjusted together using the LDT. This requires careful preparation - the right data, a diverse group of participants, and a clear structure. On Arnstein's ladder, workshops sit between Placation and Partnership.

When playing becomes participation

One of the most underestimated tools in civic engagement is fun.

Real engagement is also about excitement and creativity. When people enjoy an experience, they remember it and they come back. Playful design is not a gimmick. It is a strategy for reaching new groups and strengthening people's emotional connection to their own neighbourhood.

Three principles stand out:

The moving effect. Changing the environment itself can change behaviour. A well-known example: converting stairs into an interactive piano keyboard at a subway station led to a dramatic increase in stair use compared to escalators. The same logic applies to participation: if the act of contributing is itself enjoyable, more people will do it.

The visible effect. When people can immediately see the impact of their action, they feel real influence. Imagine a public display where casting a vote on a planning question instantly updates a visualisation of the future neighbourhood - like a glimpse into what could be. The LDT makes exactly this kind of immersive, visible feedback possible.

The exploring effect. Geocaching is a well-established community activity: people use GPS to find hidden objects. Cities can adapt this for participation. Hide a geocache in an area that needs improvement. When someone finds it, they can leave suggestions in a logbook - a "city logbook" alongside the standard one. This combines outdoor exploration with real civic input, in a format that is already beloved by many communities.

These approaches invite participation without demanding it. They are voluntary, accessible, and often joyful. And they can be directly integrated with an LDT to collect data that actually informs planning decisions.


The Masterclass: Ideathons and Hackathons

At the top of Arnstein's ladder sits citizen control - where residents are not just consulted but become the initiators of ideas and solutions themselves.

An ideathon is a creative event where diverse teams - could be students, professionals, activists, residents - collaborate to tackle real urban challenges within a defined timeframe, typically 24 to 48 hours. The format is energetic, interdisciplinary, and experimental.

In the context of an LDT, the possibilities are extraordinary. Participants work directly with realistic digital representations and datasets of their own city. Abstract planning decisions become tangible. Teams can simulate scenarios, test ideas, and see potential consequences - all before a single stone is moved.

An example: a city's Office for Youth, Family, and Inclusion could challenge participants to design inclusive play spaces for children with disabilities while using the LDT as a collaborative planning tool. What barriers does the existing data reveal? What new data would be needed? What does a truly barrier-free playground look like?

Unlike a standard workshop, the ideathon produces real output (pitches, prototypes, proposals) evaluated by a jury that includes local stakeholders. The best ideas can be taken forward. Some participants go on to work with the city directly. Others add the experience to their professional portfolio.

Beyond the ideas themselves, ideathons build skills. Agile working. Digital collaboration. Creative problem-solving. Intercultural communication. These are the future skills our cities and our citizens will need.

Honest Participation

A word of caution. Roger Hart, referencing Arnstein's work, reminds us that anything below a genuine level of influence risks being manipulative or tokenistic. Participation must be taken seriously.

This means: choosing the right format for the right goal. Being honest about how much influence citizens actually have. Documenting and evaluating every process. And above all - following up. If citizens contribute their time and ideas, they deserve to know what happened next.

The LDT does not automatically make participation meaningful. But used thoughtfully, it makes the process more transparent, more visual, and more inclusive. It lowers barriers. It reaches new groups. It turns abstract data into something people can see, touch, and respond to.

From One Click to an Ideathon: The Ladder is yours to Climb

There is no single right answer to the question: "How do we involve citizens?".

A neighbourhood survey, a participation festival, a planning workshop, a citizen forum, a hackathon - each format has its place on Arnstein's ladder. Each serves a different goal and reaches a different audience.

The key is to be intentional. Define your goal clearly. Choose the format that fits your community. Use the LDT not as a technological showpiece, but as a genuine tool for transparency and co-creation.

And remember: the goal is not participation as a marketing exercise. The goal is to shape a city or region that truly belongs to the people who live, work, travel in it.

Let's experiment. Let's involve. Let's climb.
