Interbay Crime Rate Trends — Seattle
Interbay is the low corridor between Queen Anne and Magnolia, threaded by the BNSF rail yard and 15th Avenue West. Mixed industrial, big-box retail, and a growing residential pocket along Dravus Street; home to Fisherman's Terminal and the Interbay golf course.
September 2026 in Interbay was a structurally quiet month for anomalies, with two zero-event signals as the only tracked movements. The broader 12-month picture is a different story, with robbery, burglary, and other larceny all running above prior-year levels across the trailing window.
Robbery stands out most sharply in the 12-month comparison: 14 incidents over the current year against 5 in the prior year, a 180.0% increase. Other larceny is up 38.6% (79 vs. 57) and burglary up 25.4% (74 vs. 59) year over year, while theft from vehicle and motor vehicle theft both ran lower, down 16.7% and 19.0% respectively. No single-month signals crossed the anomaly threshold this period, so the story is in the cumulative trend, not a one-month event.
Notable signals 0
Nothing notable surfaced this month — every category sits within normal range against its baseline.

Each panel: recent monthly count vs. trailing 12-month context. MoM is the most recent month vs. the one before; 12mo YoY compares the trailing year to the year before that.
What's been quietly true for a year
Spikes get attention. Sustained shifts shape policy. These are multi-quarter patterns where the past 12-month total differs meaningfully from the year before — they often precede the baseline resetting.
No sustained shifts surfaced this month.
What next month likely looks like
Forecasts trained through September 2026, with a likely range we're 95% confident the actual count will fall inside. Categories with too little recent volume — or violent categories at the neighborhood level — show no forecast and are surfaced through signals above instead. See the methodology page for the gating rules.
Aggravated Assault
Too low-volume per neighborhood for a reliable point forecast — see the rare-event and streak-break signals above instead.
Arson
Below the volume threshold for a reliable forecast — too few incidents in recent months to project from.
Burglary
Homicide
Too low-volume per neighborhood for a reliable point forecast — see the rare-event and streak-break signals above instead.
Motor Vehicle Theft
Other Larceny
Robbery
Too low-volume per neighborhood for a reliable point forecast — see the rare-event and streak-break signals above instead.
Sexual Assault
Too low-volume per neighborhood for a reliable point forecast — see the rare-event and streak-break signals above instead.
Theft from Vehicle
Vandalism
How Interbay compares
Peer neighborhoods picked by closest 12-month homicide volume — a pragmatic v1 of peer matching. Demographic / housing-stock peer matching isn't built yet (we deliberately don't ingest income or race data alongside crime). Volume similarity has the right intuition: “neighborhoods experiencing comparable homicide levels.”
Recurring local terms (last 12 months)
Top terms in incident descriptions for Interbay, excluding generic crime taxonomy. Useful as texture — what kinds of specifics show up here that don't show up elsewhere.
Hour-of-day, day-of-week, and seasonality
Distribution of bucketed incidents in this neighborhood across the full analysis window. Useful for routine context — shopping-strip thefts vs. late-night assaults read very differently when you can see when each typically happens.
How we built this page
Data → Anomalies → Forecast → Page
Incident data is pulled from SPD's Crime Data feed on Seattle Open Data, mapped to 10 NIBRS-aligned categories, and aggregated to neighborhood × category × month.Anomalies are surfaced using strict thresholds (~p < 0.01). Forecasts are Prophet with low-count gating; violent categories at the neighborhood level skip the forecast and show rare-event / streak signals instead.
Spike rule: 12-mo total > baseline mean + 2.5σ AND ≥ 20 incidents AND 6-mo confirms. Drop rule: 12-mo total < baseline mean − 2.5σ AND baseline mean ≥ 20. Rare event: any incident in the last 90 days, no prior comparable in ≥ 5 years.
