Supply, access, enforcement, and peer-city comparison. Compiled from Seattle Parks & Recreation, the Seattle Park District, Trust for Public Land ParkScore, Washington OFM, and public records requests.
Seattle's OLA count has been stuck at 14 for ~15 years while the population grew 34%. Per-capita comparison to Portland, San Francisco, Vancouver BC, and Austin. Budget analysis through Park District Cycle 2.
Walkshed coverage, peer-city OLA acreage, the Kinnear Park case study, and the pattern of illegal off-leash use that follows from insufficient supply. Interactive map of all existing, under-construction, and planned OLAs.
Where Seattle Animal Control issued 4,803 off-leash citations between January 2014 and October 2019. Interactive hotspot map, year trend, and a top-20 table — six of the top ten cited parks have no designated OLA at all. A follow-up public records request covering October 2019 to present has been filed; this page will update when received.
Seattle Parks & Recreation total budget versus dedicated off-leash area spending, 2016–2026. Absolute dollars, percentages, per-dog figures, Cycle 1 vs. Cycle 2 comparison, and a peer-city transparency table showing why the comparison is so difficult. Every row sourced.
A clearly-marked opinion page with six principles, three opinions that fall out of the data, and one policy recommendation: a time-zoned shared-use model for Seattle's parks, modeled on New York City's long-standing off-leash-hours policy. Signed by Andre Vrignaud.

This site favors explicit methodology over headline-friendly numbers. Every derived number on every page links back to its underlying CSV and, where applicable, to the script that produced it. The master reference is METHODOLOGY.md — the "show your work" index. A few caveats readers should also carry:
scripts/compute_walkshed.py (osmnx against Seattle's full OSM walk network) and scripts/population_coverage.py (2020 Census block-group overlay, area-weighted). SPR's published 2.5-mile standard covers 79.4%.
