Who Are We?

We are a team of Urban Planning graduate students from Columbia University researching the changes coming to Renca and how these changes will impact the community.

The goals of our research.

Our research aimed to understand how Renca can collectively manage the impacts of top-down change, especially with the arrival of the new metro line 7. We sought to move beyond traditional planning approaches by centering the voices of residents, recognizing that meaningful urban transformation must be shaped not just by infrastructure, but by the people who call Renca home. Through collaborative engagement, spatial analysis, and human-centered data collection, our goal was to produce insights and tools that could support inclusive, long-term development rooted in the strengths and aspirations of the community itself.

Our Values

Community-Driven Planning

We believe that the people who live in a place are the ones who understand it best. Our work in Renca was shaped by the stories, insights, and aspirations of its residents, ensuring that the planning process was rooted in local knowledge rather than external assumptions.

Bottom-Up Approach

Rather than imposing top-down solutions, we designed our research and recommendations to be shaped by those most impacted. Through participatory activities and direct engagement, we prioritized the voices of community members in identifying challenges and envisioning future possibilities.

Humanizing Data

Planning too often reduces communities to numbers and maps. We aimed to reframe that by capturing not just where things happen in Renca, but how people feel in those spaces. Our interactive map and analysis are built around emotion, memory, and lived experience, making the data personal, not just technical.
