About the 80%: An example of such a use: The city is licensing a medical marijuana dispensary at 100 main St. We want to notify the neighbors that are within 300 feet of that addresses parcel boundary. We tried to avoid including tempting things like general purpose geocoder, for example, to answer questions like “where is fishermans wharf?”. About the silos: There are at least a dozen address databases in the city – we’d like to put a dent in this number. Problems with silos: - lots of ETLs to maintain - stale data - inconsistent validations (perfectly appropriate for some use cases)

We separated the map data because we want to provide mapping and geospatial services to applications other than the address system.
