What public GIS is good for
Flagging whether a neighborhood is typically on public sewer vs septic.
Pointing to SSURGO soils that often correlate with drainage or septic friction.
Listing common water providers for a city/area when published.
What GIS cannot certify
Perc / OWTS approval or system size.
Well yield, water quality, or groundwater rights / SGMA constraints.
Hookup capacity, fees, or timeline from a utility.
Honest workflow
Start with a parcel Screen for hazards and soils context, then call environmental health and the water/sewer agency. Honesty here builds trust—and still moves buyers into a trial to see the lot-level picture.
People also ask
Can Parcel View tell me if septic will pass?
No. SSURGO and local notes are screening clues only. Environmental health and perc/design control the outcome.
Can I see if a parcel has a well on the map?
Sometimes well logs or local layers exist, but absence on a map means nothing. Confirm with sellers, title, and well records.
What should I screen first on raw land utilities?
Jurisdiction, sewer vs septic likelihood, water source options, power proximity, and hazard overlays that affect pad location—then agency calls.
