Steps
Query https://gisweb.miamidade.gov/arcgis/rest/services/Wasd/DOHSepticSystem_1_v1/MapServer/0/query with where=1=1&outFields=* to inspect the schema
Filter by permit/application number using APNO, or by system type using SYSTTYPE (OSTDS New/Existing)
Use ESTIMGPD (estimated gallons per day) and WSUPLTYP (water supply type) fields to assess site capacity and context
Check APPRDATE and FINALINSP/FINSYSAPRV to determine permit approval and final inspection/approval status
Request f=geojson for GeoJSON output, or f=json for Esri JSON with geometry
Known gotchas
maxRecordCount is 1,000 per query — large pulls need resultOffset pagination
This layer is sourced from Florida Department of Health records specific to Miami-Dade County, so it won't reflect septic systems handled outside county-managed DOH workflows
Miami-Dade also publishes an unrelated Open Data Hub property-appraisal dataset under the broader miamidade.gov domain — don't confuse the two; this route is specifically the Wasd/DOHSepticSystem_1_v1 MapServer layer
