For a parcel in or near Asbury, the Asbury GIS map shows parcel boundaries plus basic tax data. In this Asbury guide: where that map lives, the fastest ways to search, and the limits worth knowing.
Finding a lot on the Asbury GIS map
Parcel maps here are usually run by the county, not the town, so for Asbury the go-to is the Dubuque County Beacon site.
Where the parcel data lives
Lots and tracts near Peosta are published on the Dubuque County Beacon site, a viewer that needs no account. If you're looking near Peosta, type a street address, an owner's name or a parcel number, then pick the result to center the map on it. With a lot near Peosta, the parcel card usually lists the owner of record, acreage on the tax roll, a parcel ID and sometimes recent sales.
A word on accuracy
Listed acreage is an assessed number; only a licensed surveyor sets the real boundary on land around Dubuque. Owner names and values update on a schedule, so a fresh transfer around Centralia can take weeks to appear.
Where Asbury fits in
Asbury is part of Dubuque County, Iowa, and the county assessor maps its lots. If the land is near Graf, city or town hall handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Lots just outside the city limits toward Graf often follows county rules, not municipal ones.
Getting answers from the right desk
If the acreage or value on a parcel near Peosta looks off belong with the County Assessor, which maintains the tax roll. Questions about what you can build around Graf are for the local planning and health departments, town or county, depending on location.

Where the recorded documents are
When the details count, get the recorded deed through the County Recorder; the parcel map near Peosta only summarizes it. Long-held tracts around Graf can sit on a long string of deeds, so a title company is worth hiring before a purchase.

Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though corrections make some sections near Sageville odd-sized. Write down the legal description for the tract near Dubuque before you request a deed or survey.
