North Hampton has two very different kinds of flood risk inside one small town. On the ocean side, storms push water and stone across Route 1A at Little Boar’s Head, Bass Beach and North Hampton State Beach. Inland, the problem is fresh water: brooks and the Winnicut River overtop road crossings after heavy rain. The town’s hazard plan treats both, and flood insurance has to fit whichever one your house faces.
We are a family-owned independent agency on Islington Street in Portsmouth, a short drive up Route 1. We have written homes on the Seacoast since 2005 and compare 40+ carriers for the home policy, then match it with NFIP or private flood. You can reach us at (603) 431-4020.
Key takeaways
- North Hampton is two NFIP communities: the town (since June 3, 1986) and the Little Boar’s Head Village District (since June 27, 2017).
- Current FEMA maps for both took effect January 29, 2021.
- July 2023 state figures in the hazard plan show 32 single-family NFIP policies in the town and 23 in the Village District.
- The plan’s chronic flood list runs from Route 1A along the ocean to Winnicut River and Little River crossings well inland.
- A home NFIP policy stops at $250,000 on the building, which many North Hampton houses exceed.
- New NFIP policies are written through Selective, and we quote private flood markets next to them.

Two flood communities in one town
Little Boar’s Head was created by the Legislature in 1905 and covers the seaward part of North Hampton. It keeps its own master plan and zoning, and in 2017 it became its own NFIP participant with floodplain rules that the town describes as effectively identical to its own (North Hampton Coastal Hazards and Adaptation chapter, adopted May 17, 2022). The town itself joined the regular program on June 3, 1986, and the town has accepted the flood study that came with the January 29, 2021 maps (North Hampton Hazard Mitigation Plan Update 2024, public review draft; NHDES notice on the 2021 Rockingham County maps).
For an owner, the practical effect is small but real. The flood application names the community, floodplain permits come from whichever body has zoning authority over your lot, and the state reports policies and losses for each one separately. If you are buying near Ocean Boulevard, ask which side of the district line the house sits on before you order an elevation certificate.
NFIP policies and losses, town and Village District
The hazard plan reprints state Office of Planning and Development figures, current to July 2023:
| Town of North Hampton | Little Boar’s Head Village District | |
|---|---|---|
| Single-family policies in force | 32 | 23 |
| Coverage in force | $7,880,000 | $6,518,000 |
| Paid losses since 1978 | 53, totaling $515,098 | 3, totaling $144,654 |
| Repetitive losses | 5 (payments of $67,665) | 2 (payments of $110,648) |
| Joined NFIP | June 3, 1986 | June 27, 2017 |
Two things stand out. The Village District has fewer policies but much more coverage per policy, which is consistent with larger houses near the water. And the same plan counts only twelve permanent residential structures in the mapped flood zone, while the two communities together carry 55 single-family policies, which suggests many owners carry flood coverage outside the mapped zone, where lenders generally do not require it. Treat these as program counts, not a judgment about your own house.
The ocean side: Route 1A, Bass Beach and Philbrick’s Pond
The hazard plan’s list of chronic flood spots includes two locations on Route 1A along the ocean, south of Route 111. The 2022 coastal chapter says only a few North Hampton locations are directly hit by projected sea-level rise, chiefly the low stretches of Route 1A by Bass Beach and North Hampton State Beach, and it shows Ocean Boulevard at the Hampton line flooding at four feet of rise (coastal chapter, 2022). The 2024 plan also proposes working with NHDOT and Rye on closing Route 1A during coastal storms, because sightseers drive and park along it.
Behind the road, Philbrick’s Pond drains to the sea through Chapel Brook, an old trolley berm culvert and a box culvert under Route 1A. A 2018 engineering study found that a stone weir at the Route 1A inlet was cutting the marsh’s tidal range, and the town removed the weir in January 2022 under a state wetlands permit. The study projected roughly 11 more inches of tidal range in the marsh. The chapter notes that the town is still working with NHDOT, NHDES and neighbors on the two culverts, because the restrictions also raise hazards for adjacent homes.
The inland side: the Winnicut, the Little River and Mill Pond
North Hampton drains two ways: northwest through the Winnicut River toward Great Bay, and east to the ocean through the Little River, Philbrick’s Pond, Berry’s Brook and Bailey’s Brook. The hazard plan names these inland roads as places where flooding recurs or is likely:
| Road | Water |
|---|---|
| Lovering Road and Walnut Avenue | Winnicut River (NHDOT has since replaced the Walnut Avenue culvert) |
| Winnicut Road near Deer Run Road | Barton Brook |
| Mill Road | Mill Pond on the Little River |
| Woodland Road | Little River |
| Chapel Road | Stream crossing |
| North Road at Cherry Road and near Birch Road | Local drainage |
| Route 1 at Juniper Road and at the Chestnut and Hawthorne Road neighborhood | Local drainage |
| Knowles Field | Knowles Pond |
| Old Locke Road near Pond Path | Two new town culverts installed since 2018 |
The plan says the culvert work since the last update has left no known inland flood impacts, and it classifies Mill Pond Dam on the Little River as low hazard. It still lists raising Old Locke Road as a new action, noting that thirty-eight residents are trapped there during flood events. Being cut off is not damage, but it is a reason to keep a flood policy and an evacuation plan current on that road.
Groundwater, septic systems and what flood insurance does not do
There is no town sewer in North Hampton, so every home uses an on-site septic system. A Rockingham Planning Commission review for the Conservation Commission, cited in the 2022 chapter, found that 229 developed parcels in North Hampton and Little Boar’s Head may be susceptible to septic impacts because they sit within existing flood zones (coastal chapter, 2022). As sea level rises, coastal groundwater rises with it.
That matters for insurance because a flood policy is built around a general flooding event, such as water covering two or more acres of normally dry land or two or more properties (FloodSmart). A slowly rising water table or a septic field that stops draining is usually a maintenance or seepage problem, not a flood claim. Where each kind of water lands is covered in our basement flooding article.
Looking ahead: sea-level rise planning
The state’s 2020 coastal flood risk guidance says coastal New Hampshire is likely, about a two-in-three chance, to see 0.5 to 1.3 feet of relative sea-level rise between 2000 and 2050 under its recommended scenario (New Hampshire Coastal Flood Risk Summary, Part II). The hazard plan cites the Rockingham Planning Commission’s 2015 assessment, which estimated that a 6.3-foot rise plus storm surge could affect $192,869,300 of North Hampton infrastructure and homes. These are planning scenarios, not forecasts for a given house, but they explain why we suggest flood coverage even for homes just outside today’s zones.
Choosing between NFIP and private flood here
For the federal program, new NFIP policies are written through Selective. On the private side we quote Neptune Flood, Beyond Floods, CatCoverage, Aon Edge, Flow Flood and The Flood Insurance Agency (TFIA). A few points tend to decide it in North Hampton:
- Limits. With an average assessed residential structure of $770,783 in the 2023 figures, the NFIP’s $250,000 building limit leaves many homes short. Private flood or excess flood fills the gap.
- Basements and finished space. NFIP basement coverage is narrow, mainly the furnace, water heater, panel and foundation. Finished lower levels near the Winnicut or Little River need a careful look.
- Living expenses. A standard NFIP home policy does not pay to live elsewhere while repairs are made. Some private policies do.
- Timing. NFIP coverage usually takes effect 30 days after purchase, with some exceptions such as a loan closing (FloodSmart). Private carriers set their own waiting periods.
- Wind. Wind and wind-driven rain belong on the homeowners policy, and many carriers apply a separate wind or hurricane deductible near the coast.
For the house itself, see our North Hampton insurance agency page and the New Hampshire coastal home insurance guide. Neighbors to the south can read Hampton flood insurance, and owners up the coast can read Portsmouth flood insurance. Our post on coastal flood and wind insurance in New England explains how the two policies split a storm.

Frequently asked questions
Am I in the town or in Little Boar’s Head for flood insurance?
It depends on the address. The Little Boar’s Head Village District covers the seaward edge of North Hampton, has its own zoning and joined the NFIP on its own on June 27, 2017; the rest of town has been in the program since June 3, 1986 (North Hampton coastal hazards chapter, 2022; North Hampton hazard plan, 2024 draft). Both are on the Rockingham County FEMA maps that took effect January 29, 2021. We confirm the community on the application for you.
Where does North Hampton flood when it is not a coastal storm?
Mostly at stream and river crossings. The hazard plan lists Lovering Road and Walnut Avenue at the Winnicut River, Winnicut Road at Barton Brook, Mill Road at Mill Pond, Woodland Road at the Little River, Chapel Road at its stream crossing and spots on Route 1 and North Road. A house well back from the ocean can still have a flood problem on its driveway or in its basement.
Does my homeowners policy pay if Route 1A storm water reaches my house?
No. Homeowners policies exclude flood, and that includes surge and wave splash-over coming off the ocean side of Route 1A. Wind damage to the roof or windows in the same storm is usually a homeowners claim. Backup through a drain is a third issue that some policies cover by endorsement; see our sewer backup guide.
Is rising groundwater or a flooded septic field covered by flood insurance?
Usually not on its own. An NFIP flood policy responds to a general and temporary condition of flooding of normally dry land, such as two or more acres or two or more properties. Slow seepage, a high water table or a failing septic system without that broader flooding is generally outside a flood policy. Read the definitions in your own policy, and ask us how your homeowners policy treats sudden water damage.
How large a flood policy can I buy for a big North Hampton house?
On a home, the NFIP stops at $250,000 of building coverage and $100,000 of contents coverage. The town’s hazard plan puts the average assessed value of a North Hampton residential structure at $770,783 in 2023, so many homes here need more. A private flood policy can carry higher limits, or an excess policy can sit on top of the NFIP. Our North Hampton high-value home page covers the home policy side.
What should I send for a North Hampton flood quote?
Start with the street address and year built. Then tell us the foundation type, whether the house has a basement and how high the heating system and electrical panel sit. Add an elevation certificate if one exists, any earlier flood claims and the declarations page from your homeowners policy. Request a quote. There’s no obligation to buy. You can fill in the form on this page, send our flood quote request or call (603) 431-4020.
The town next door has its own guide: Hampton Falls flood insurance covers the Taylor River and Route 1 side of the line.
