The county is predominantly sewered: only 2,955 of 210,591 classified parcels are on septic. Septic properties near Cedar Mill are the exception, which is exactly why owners often do not know they have one. The county publishes a records portal, but reaching the documents needs an account or a login, so budget for that step rather than expecting an open search.
