That is a substantial partial collection rather than a complete one, so a Sequim property may or may not appear in it, and the county archive remains the authority. Of the parcels we have classified in the county, most are on septic rather than sewer (19,352 of 31,080). A property near Sequim is more likely than not to have its own system. 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.
