The real power of data lies in telling a clear, people-first story.

Nichole Dunn discussed how data is not just about numbers, but is about showing residents how decisions are made and why they matter. She suggested that cities connect data to community impact to build trust through transparency and ensure residents see themselves reflected in the outcomes.

Let data guide your efforts.

In response to a surge in e-bike collisions, Carlsbad launched a cross-departmental Safer Streets initiative focused on engineering, enforcement and education. The city revamped their data infrastructure to better track bike and e-bike incidents and then mapped high-risk areas. This analysis directly shaped infrastructure changes like traffic calming, signal adjustments and new bike lanes.  Rachel Maltz emphasized that Carlsbad’s success at addressing the issue was due to the fact that they focused on using data to guide real action, not just to check a box. Her advice to other cities was to not collect data for its own sake, but to build systems that turn insights into policy and investment decisions.

Start with the end in mind and engage all stakeholders early for lasting impact.

San Diego built a strong data foundation by mapping its tree canopy and assessing street conditions with LiDAR — a remote sensing method that uses light in the form of a pulsed laser to create high-resolution models of ground elevation and surface characteristics — and in-person surveys to support climate goals and infrastructure planning. The city then made this data accessible through an online portal where residents can submit comments and requests. This portal had the additional benefit of improving data transparency to address operational, public relations and political challenges. Bethany Bezak suggested that cities who want to use data in a similar way should involve key stakeholders early, and ensure continuous investment in both the data infrastructure and the community’s engagement to make data truly actionable.
