Atkinson at a glance

The U.S. Census Bureau estimates 7,397 Atkinson residents as of July 1, 2025 (7,094 in the April 2020 estimates base). The town’s Natural Hazard Mitigation Plan Update 2025, prepared with the Rockingham Planning Commission and adopted by the Board of Selectmen on May 19, 2025, describes Atkinson as a semi-rural commuter community of about 11.2 square miles, including 0.2 square miles of surface water.

Atkinson lies mostly in the Merrimack River watershed, with the Lower Merrimack and Spickett River sub-watersheds, and four named brooks: Colby, Hog Hill, Foote and Kelly. Ponds include part of Island Pond (67 of its 498 acres are in Atkinson), Hodges Mill Pond, Blunts Pond, Stewart Farm Pond and Hovey Meadow Pond. The plan counts about 1,137 acres of poorly or very poorly drained wetland soils. It says 52% of the town’s land is in residential use and 21% is protected open space, with commercial areas in the northwest and southeast corners.

The plan notes 235 residential building permits since 2019. For insurance, that means mostly single-family homes in scattered neighborhoods, some newer construction, and a smaller number of homes near the ponds, brooks and wetlands where flood maps matter.

Where you live in Atkinson changes the policy

• Island Pond and Hog Hill Brook. The plan says the small amount of road in the 100-year floodplain (about 0.21 miles, 0.3% of town roads) is mostly in the northwest part of town around Island Pond and along Hog Hill Brook.
• South of Route 111, between Main Street and East Road. The Highway Department lists this area among the places flooding affects.
• The southeast corner. The plan lists the area along the border with Plaistow and Haverhill, Massachusetts, as another flood area.
• Beaver dams. The committee flagged four large beaver dams that could cause flooding if breached: two on Hovey Meadow Pond off Merrill Drive, one on Stewart Farm Pond and one on Sawmill Swamp.
• Outside the mapped zones. About 287 acres, roughly 4% of town, is in the 100-year floodplain, mainly A and AE zones tied to large wetland complexes. The plan says several flood-prone areas sit outside those zones, and that land use in the flood areas is mostly low-density residential.

Flood coverage in Atkinson

The plan says Atkinson participates in the NFIP (it gives a regular-program entry date of March 3, 2009), with current flood maps dated 2005. Its table from the NH Office of Planning and Development, as of June 2024, shows zero policies in force, zero paid losses since 1978 and no repetitive-loss properties.

In other words, almost no one in Atkinson carries flood insurance, while the plan still rates flooding a high risk and names flooding as the town’s most common hazard. It records a June 2021 thunderstorm that flooded roads and yards, and heavy rain in July 2023 and in winter storms in 2022, 2023 and 2024. The town inspects culverts every year; that helps the roads, and it does not decide whether your house needs a flood policy.

A homeowners policy will not pay for a river or pond over its banks, or for surface water. Flood is its own policy. Check your address on the FEMA Flood Map Service Center and ask us to compare NFIP and private flood.

• NFIP through Selective. We write National Flood Insurance Program policies through Selective, a Write Your Own carrier. The NFIP covers up to $250,000 for the building and $100,000 for contents. New policies generally have a 30-day waiting period (see FloodSmart), so buy before storm season, not during it.
• Private flood. When a home costs more than the NFIP building limit to rebuild, or you want coverage the NFIP leaves out, we compare Flow Flood, Neptune Flood, Beyond Floods, The Flood Insurance Agency, CatCoverage and Aon Edge. Each one decides address by address.
• Elevation certificates. If you have one, send it. If the house has been raised or has flood vents, it can make a real difference in how flood carriers rate it.

Water backup (sewer, drain or sump pump failure) is an add-on to homeowners; flood is separate. If your basement is finished, ask about both. See basement flooding coverage and our flood insurance overview.

Other hazards the plan ranks high

The 2025 plan rates flooding, hurricane and high wind events, and climate change highest, followed by severe winter weather, wildfire, infectious disease, extreme temperatures and drought, all in its high band. Earthquake is profiled as well.

It says Hurricanes Sandy and Irene caused localized flooding and power loss, and high-wind events in 2016, 2018, 2023 and 2024 brought extensive outages and downed wires and trees. The state’s Dam Bureau lists twelve active dams in town; one, the Atkinson Country Club Lagoon Dam, is classified significant hazard. Most wildfires have been minor brush fires, with structures near large open vegetated areas most exposed. We review wind, winter and water-backup coverage on every Atkinson homeowners quote.

Winter, trees and wind in Atkinson

The plan records six severe winter storms in five years, including two 2018 nor’easters, a December 2022 snowstorm and nor’easters in March 2023 and March 2024 that brought outages. It cites the 2008 ice storm, which left residents without power for over a week. For homeowners, that means ice dams, frozen pipes, heavy snow loads and trees on roofs. These are generally homeowners claims, subject to your deductible and policy terms. A properly sized wind and all-perils deductible, and a roof in good shape, do more for most homeowners than any single add-on. Water damage from a burst pipe is usually covered when the home is heated and occupied; long vacancies can change that, so tell us if the house will sit empty.

Larger homes

Under about $2 million, most of our 40+ carriers are in play. In New Hampshire, Andover generally writes homeowners up to about $1.5 million, or closer to $1 million for homes far from a hydrant or fire station. Around $2 million to $3 million, Hanover is often a fit; above $3 million, Cincinnati; and at $5 million and up, Chubb. Each carrier underwrites the specific house, so these are starting points, not promises.

Larger homes in Atkinson can carry rebuild costs well above what a quick estimate suggests, so we start with a replacement-cost estimate, not the purchase price or assessment. See high-value home insurance in New Hampshire.

Condos, rentals and older homes

Your HO-6 condo policy covers what the association’s master policy does not. See condo insurance in New Hampshire. If you rent out a house in Atkinson, you need a dwelling or landlord policy; for New Hampshire landlord and habitational placements we work with Vermont Mutual, Andover, Safety, Concord Group and Providence Mutual. For an older home, carriers will ask about the roof, heating, wiring, plumbing, well and septic.

Renters and tenants in Atkinson

If you rent in Atkinson, your landlord’s policy covers the building, not your belongings or your liability. A renters policy covers both, plus extra living costs after a covered loss. We shop renters coverage across our carriers, and Progressive Home is one of them; we use Progressive Home for renters policies only. Landlords who own two- to four-family buildings can see landlord insurance.

Auto, umbrella and the rest of the household

Most Atkinson households also need auto insurance, and many add a personal umbrella. If you keep a boat on Island Pond, we can add it to the same review. We quote them with the home so the liability limits line up, and we put rentals, second homes, boats and valuables under the same review. One agent, one renewal conversation.

Common coverage gaps we see in Atkinson

• A dwelling limit based on the purchase price or assessed value instead of the cost to rebuild
• No water backup coverage on a house with a finished basement
• Personal property limits that have not kept up with what the household actually owns
• Liability limits on the home and auto that do not line up with an umbrella, or no umbrella at all
• No ordinance or law coverage on an older home that would need code upgrades after a loss
• No flood policy on a home near Island Pond, Hog Hill Brook or the wetlands south of Route 111
• Well, septic or outbuilding details left off the application

Most of these are straightforward to fix once someone reads the declarations pages side by side, and that is the first thing we do in a review.

Before storm season in Atkinson

• Know your hurricane or named-storm deductible in dollars, not just as a percentage
• Photograph or video each room so a contents claim is easier to document
• Keep your declarations pages, flood policy and any elevation certificate somewhere you can reach from your phone
• If you are thinking about flood coverage, buy it well ahead of a storm because of the waiting period
• If you live near Island Pond, Hog Hill Brook or another plan-listed flood area, keep sump-pump and elevation records handy
• Know how you will keep heat and water going in a week-long outage like 2008

Buying a home in Atkinson

Start the insurance conversation before you are under contract, not the week of closing. Send us the listing and the inspection report when you have it. The report answers most of what carriers ask: roof age, electrical panel, heating, plumbing and any water in the basement. Near Island Pond, the brooks or the wetlands, ask for any elevation certificate and the seller’s flood history. Get well and septic details into the file early. We line up the homeowners binder, and a flood binder if you need one, so both are ready for your lender.

How a Atkinson home quote works

• Tell us about the house: address, year built, square footage, roof age and updates to wiring, plumbing and heating.
• Send your current declarations page so we can compare like for like and point out limits that look short.
• We shop the carriers that fit and lay the options out side by side, with the differences in coverage, deductibles and storm terms, not just price.
• You choose, and we handle the switch, including your mortgage company and the effective date, so there is no gap.

Frequently asked questions

Do you insure homes in Atkinson, NH?

Yes. We insure Atkinson homes from our Portsmouth office at 601 Islington St, and by phone, email and online. Call (603) 431-4020.

Does Atkinson flood?

In documented spots. The town’s 2025 hazard mitigation plan calls flooding the most common hazard and lists areas around Island Pond, along Hog Hill Brook, south of Route 111 between Main Street and East Road, and along the Plaistow and Haverhill border. As of June 2024 it showed no NFIP policies in force. Check your address on the FEMA Flood Map Service Center.

Does homeowners insurance cover a flooded basement?

Not from flood. Water backup from sewers, drains or a sump pump is an add-on, and rising or surface water needs a flood policy.

Who writes your NFIP flood policies?

We write NFIP policies through Selective, and we compare private flood from Flow Flood, Neptune Flood, Beyond Floods, The Flood Insurance Agency, CatCoverage and Aon Edge.

Do you charge fees?

No. We don’t charge fees on any policy we write, including homeowners, condo, renters, landlord, dwelling and auto.
