Steps
Query https://gis.browncountywi.gov/arcgis/rest/services/POWTS/POWTS_and_ShorelandPermits/FeatureServer/1/query with where=1=1&outFields=* to see the schema
Filter by PermitType (A=At Grade, C=Conventional, H=Holding Tank, I=In Ground, M=Mound) to isolate a specific system category
Use IssueDate, ExpirationDate, and InspectionDate to build a permit lifecycle/compliance timeline
Check NewTankInstallDate and AgeOfOldTank/OldTankReplaced fields when researching tank replacement history for a parcel
Follow the PermitScan field's link to retrieve the scanned original permit image where available
Known gotchas
maxRecordCount is 30,000, high enough that naive full-table pulls are possible but slow — filter server-side by ParcelNumber or date range instead of pulling everything client-side
This service covers holding tanks, mounds, and other POWTS types in one layer — the PermitType code, not the layer name, tells you the system type
No authentication required, but as a small-county GIS server it has no documented uptime guarantee
