Tracking down the Mahtomedi plat map
For a subdivision near Dellwood, the deed or parcel record often names the subdivision and plat reference; use it to request a copy.
Pulling up a parcel
Go first to the Washington County ArcGIS parcel map; it includes each tax parcel from Dellwood to White Bear Lake. Around Dellwood, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. If you're looking near Dellwood, the parcel card typically gives the owner of record, acreage on the tax roll, the parcel number and in many cases the last transfer.
Where the recorded documents are
The map is an index, not the title: deeds, subdivision plats and easements covering ground around Pine Springs sit with the County Recorder. Closer to Birchwood Village, have ready the document number shown in the record panel and the lookup takes minutes.
City limits and county records
