Getting started with the Hillsborough flood zone map
The official source is FEMA's Flood Map Service Center: type an address near Carrboro, and pick the FIRMette or map view. Vacant ground around Carrboro can still be found: pan from the closest town and click inside the land.
The viewer Orange County publishes
Your first stop is the Orange County parcel viewer; it maps each assessed parcel around Durham and Carrboro. If you're looking near Mebane, enter a street address, an owner's name or a parcel number, then pick the result to center the map on it. For land near Durham, the record panel normally shows the owner of record, acreage on the tax roll, the parcel number and often a sale date.
City limits and county records
Hillsborough sits in Orange County, North Carolina, so its parcels are on the county's map. Hillsborough is also the county seat, which puts the Register of Deeds close by. For acreage around Mebane, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Lots just outside the town limits toward Durham generally follows county rules rather than the town's.
Zones on the Hillsborough flood zone map
For a tract near Carrboro, zones beginning with A or V mark the Special Flood Hazard Area, meaning a 1% or greater chance of flooding each year. With a lot near Durham, minimal risk is not no risk: FEMA notes that many claims come from moderate- and low-risk areas.
Water near Chapel Hill

Land on the county line
Orange County meets Alamance County, Caswell County, Chatham County, Durham County, and Person County, and each of those keeps its own parcel map. A tract near the line by Durham can show up across two assessors' files, so open the adjacent map before you assume the acreage.

Parcel lines are drawn for taxes, not measured on the ground, so a tree line near Carrboro may sit some distance off the line on screen. On ground around Mebane, records update in batches, so a deed recorded last month might lag behind.
Questions to ask before you buy
Ask the listing agent whether the home has flooded for the house near Durham; an insurance quote early avoids surprises.
