Alsea is a census-designated place in Benton County, Oregon. The Census Bureau puts its internal point at 44.381815, -123.595831 and its land area at 0.16 square miles. Septic permitting and record keeping happen at the county level, not the census-designated place level, which is why every figure below is attributed to the county and linked back to the county page it came from.

Our collection for Benton County, Oregon is small, at 123 septic records. Treat it as a starting point for a Alsea property rather than a search that settles the question. The county is genuinely mixed: 6,366 of 25,953 classified parcels are on septic and the rest are sewered. Which side of that line a Alsea address falls on is worth establishing before anything else. The county publishes a records portal that we were able to search without creating an account, which makes checking a specific parcel something you can do yourself in a few minutes.
