Seabrook, NHInc. 1768
Seabrook is the southernmost town on the New Hampshire coast, bordering Massachusetts and Salisbury. The Seabrook Station Nuclear Power Plant is the town's most significant feature, and the Route 1 commercial corridor — drawing Massachusetts shoppers — is the other. The beach area has seasonal and year-round residential properties with direct Atlantic coastal exposure.
For property professionals, Seabrook's nuclear plant creates unique considerations — property values and insurance in the plant's vicinity are affected by the presence. The beach area brings coastal flood and storm risk, and the commercial corridor adds retail property to the mix.
