Steps
Query the ArcGIS MapServer layer at https://geo.sanjoseca.gov/server/rest/services/OPN/OPN_OpenDataService/MapServer/502
Use standard Esri REST query parameters (where=1=1, outFields=*, f=geojson) to pull all segments, or filter by street name
Alternatively pull the CSV/GeoJSON mirror from the San Jose Open Data Portal (data.sanjoseca.gov, CKAN) for a static bulk extract
Note the PCI methodology: full electronic assessment every 3-5 years, with off-years estimated via a usage-based algorithm
Known gotchas
PCI values in off-cycle years are model-estimated, not directly measured — treat integer-level precision cautiously outside assessment years
This is a single-city pattern; many US cities publish similar PCI layers via ArcGIS Hub (e.g. San Jose, Sioux Falls) but layer index numbers and field names are not standardized across cities and must be rediscovered per city
