Joining with parcels
The Regrid Parcel UUID (the ll_uuid column) in the Matched Address data connects address records to the ll_uuid column in the parcel data. One parcel can have many addresses. One address can belong to multiple parcels. That is, multiple instances of the same a_id may exist with different ll_uuid values. The combination of ll_uuid and a_id in the data is unique.
