About
Bellevue, Washington, up close.

How it is made
From public records
Every figure names its public source, and a figure from a records request names the request, so you can get the same file.
With AI, reviewed
The research runs on software and AI agents built for it, pages are drafted and edited with Claude and OpenAI’s Codex, and the line drawings are made with an AI image model. A person reviews every page.
Independent
Self-funded. Any funding, client or stake in Bellevue housing or land is disclosed here and on the pages it touches.
Corrections and contact
Findings that turn out wrong keep the original beside the fix.
Corrections logFor reporters, city staff, researchers and anyone deciding something in Bellevue. The data behind every figure is available, and collaborations are welcome.
