Ahead of any purchase around Hooksett, check the Concord flood zone map: the zone on that map shapes insurance, permits and resale. In this Concord guide: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the NHDOT Parcel Mosaic Viewer.
The Concord flood zone map: start here
Start with FEMA's Flood Map Service Center: type an address near Pittsfield, and choose the dynamic map. A tract near Hooksett without an address can still be found: search the nearest road and click inside the land.
Getting to the right map
Begin with the NHDOT Parcel Mosaic Viewer; it covers each tax parcel in the county, Henniker included. If you only know roughly where the land is, pan along the nearest road and click the parcel itself, which applies near Loudon as much as anywhere. With a lot near Loudon, the parcel card normally shows the owner of record, acreage on the tax roll, the parcel number and in many cases the last transfer.
Next door to Merrimack County
Merrimack County borders Belknap County, Grafton County, Hillsborough County, Rockingham County, and Strafford County; every one of them runs a separate parcel map. Acreage along the edge near Franklin can show up across two assessors' files, so open the neighboring map before you assume the acreage. Our state page lists each neighboring county map across New Hampshire.
Water near Franklin
Small streams around Henniker aren't always studied in detail, so ask neighbors about past flooding. Wet ground around Henniker is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
A word on accuracy
Acreage on the record is a tax-roll number; just a licensed surveyor establishes the real lines for a parcel near Loudon. For a parcel near Loudon, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Merrimack County in a few facts
Concord serves as the county seat, which is where the courthouse records live. You'll also find Loudon, Hooksett, Pittsfield, and Henniker, each with its own cluster of lots. About 157,103 people call Merrimack County home (Census Bureau estimate, 2023) across about 933 square miles. Merrimack County dates to 1823, which matters when you trace an old farm's title. Landmarks such as John Hay National Wildlife Refuge are easy to spot when you zoom out from Loudon.
City limits and county records
Concord sits in Merrimack County, New Hampshire, and the county assessor maps its lots. It's also the county seat, which puts the county Registry of Deeds close by. For property near Franklin, city or town hall handles things like zoning, permits and utilities within town limits, while the county keeps the tax map. Lots just outside the city limits toward Loudon generally answers to county rules, not municipal ones.
A short flood checklist
Request about past flood claims on the property near Pittsfield; getting a quote early keeps the budget honest.
The paper trail behind a parcel
The map is an index, not the title: recorded deeds, plats and easements for land near Pittsfield are filed with the county Registry of Deeds. Older tracts around Warner may trace back through several deeds, so a title company is worth hiring before a purchase.
Zones on the Concord flood zone map
An AE label includes a base flood elevation (BFE), which plain A zones lack; builders around Henniker design to it. Near Hooksett, shaded Zone X marks moderate flood hazard, roughly the 100- to 500-year range; plain X, or C on older maps, is minimal risk.
Matching the zone to the lot lines
FEMA doesn't draw property lines, so check the NHDOT Parcel Mosaic Viewer too for the outline of the tract near Pittsfield.
Sections, lots and bearings
Tracts outside towns near Loudon are often described by metes and bounds, a series of courses and distances from a starting point. Platted lots around Hooksett refer to a recorded plat, which is simpler to follow. Write down the legal description for the tract near Loudon before you request a deed or survey.
Lenders and permits
For land near Hooksett, ask for an Elevation Certificate: it records the building's elevation against the base flood. Building or adding on near Pittsfield in a mapped zone often needs a floodplain permit; check with the county or town building office early.

For most people, a BFE near Warner tells builders how high the lowest floor should be; local rules may require building above it.
