# The catalyst map

Every pin is a development catalyst (a transit project, campus, redevelopment, or upzoning) with its entitlement status verified against the public record (CEQA filings, commission votes, permit data). The background is twenty-five years of _measured_ home-value change by ZIP. Drag the slider and watch what actually happened. Or flip the layer to crime friction: measured per-resident incident levels and three-year trends, straight from each city’s own published data — where a city publishes it. This page shows history and records; it makes no predictions.

Catalyst status (public record)

Home values: Zillow ZHVI (ZIP, smoothed, seasonally adjusted). Boundaries: U.S. Census ZCTA. Catalyst statuses verified against CEQA, city legislative records, and permit data; dates in each pin. Diamond markers are events from our graded catalyst archive; where a clean measured result exists, the pin shows it. Colors are what already happened, never a forecast.
