The Reports
We publish a data-driven report series on noise in Boulder’s University Hill neighborhood, built from Boulder Police dispatch records and the City of Boulder open-data portal. Every figure can be independently reproduced; our analysis data available on request.
Understanding Noise Pollution in Boulder (September 2026)
Where Boulder’s noise comes from, who bears it, and what the calendar proves: 70% of the city’s noise complaints come from within a fifteen-minute walk of CU; 28,000 permanent residents absorb them at 4.1 times the rest of the city’s rate; when the students leave, the noise leaves. Every dataset and script is published.

Complaints hit record levels despite an enforcement surge; tickets doubled but follow only 1 call in 21; the houses named in Report #1 went quiet and new houses took their place. Publishing shortly — we are folding in a pending Boulder Police records request first.

Three years of data: 37% of the problem from 24 addresses; enforcement failing to deter chronic offenders.

- Complaints are concentrated: a few dozen addresses of 2,049 in the initial zone of focus drive most of the problem.
- The problem is predictable: 49% of complaints occur Thursday–Saturday, 9 p.m.–2 a.m.
- Consequences work: every house named in our first report saw complaints collapse. Deterrence rotates to whoever is not being watched — which is why the watch list is permanent.
- Enforcement is improving but thin: citations doubled in 2026, yet warnings still outnumber tickets five to one.


Get each report when it publishes
We send an email when a new report goes out and when the watch list advances — a few times a year, nothing else.
You’re on the list. We’ll write when the next report publishes.
The list is used for these emails and nothing else, and we never publish resident names. We remove you the moment you ask.
