Where the Aliquippa flood zone map lives

The free map to start with
Begin with the Beaver County parcel viewer; it includes each assessed parcel in the county, Monaca included. If you only know roughly where the land is, zoom in from Conway and select the outline. On ground around Economy, the parcel card usually lists the owner of record, assessed acreage, a parcel ID and sometimes recent sales.
A short flood checklist
Ask the seller about past flood claims for the house near Ambridge; getting a quote early avoids surprises.
Next door to Beaver County

A tract near the line by South Heights can show up across two assessors' files, so look at the adjacent map before you assume the acreage. If you're looking near Monaca, our state page lists each bordering county map for Pennsylvania.
Using it on a phone
The parcel map usually runs in a mobile browser, useful out on a road near Monaca, but coverage can be spotty out of town. A printout of the tract near Monaca is a good backup.

Where Aliquippa fits in
Aliquippa is part of Beaver County, Pennsylvania, so its parcels are on the county's map. With a lot near Baden, city or town hall handles matters such as zoning, permits and utilities inside its limits, while the county keeps the tax map. Lots just outside the town limits out by South Heights usually answers to county rules rather than the town's.
Zones on the Aliquippa flood zone map
Zone AE includes a base flood elevation (BFE), while plain Zone A does not; that elevation drives building rules near Monaca. In and around Monaca, a low-risk label isn't a guarantee: FEMA notes that floods happen outside mapped zones too.
Lining it up with the parcel map
FEMA's map shows zones but not ownership, so check the Beaver County parcel viewer too for the outline of the tract near Monaca.
What a flood zone means for a buyer
If the land is near Baden, an Elevation Certificate from a surveyor helps: it compares the building to the BFE. Building or adding on near Economy in a mapped zone usually means extra permit review; ask the local floodplain administrator early.
Deeds, plats and who keeps them
For anything that matters, request the recorded deed through the Recorder of Deeds; the parcel map near Economy only summarizes it. Near Economy, have ready the document number from the tax record to skip a name search.
