Wabasha County provides a GIS (geographic information system) tool called Beacon. Beacon provides parcel and tax data, and has tools for measurement of parcels. (Please note that parcel boundaries may not be accurate on a GIS system. Property pins must be located for determination of setbacks.)
The document links below are PDFs of city infrastructure and other maps. New or updated maps may be available from time-to-time. Feel free to call to see if any exist.
The City has scanned several plat maps into PDF files.
