Restoration Projects in New Hampshire

Culvert InstallationSince 1990, NHCP has been heavily involved in salt marsh restoration by funding numerous projects through the Section 306A program. Among these have been projects in Rye, Hampton, and Seabrook that have restored over 100 acres of marsh. These projects include replacing inadequate culverts, removing fill, and Phragmites mitigation.

In 1994, the Natural Resources Conservation Service (NRCS) identified 31 tidal restrictions on the coast. Of these, 15 have been eliminated, restoring approximately 720 acres of marsh. Of the remaining 16 restrictions, 4 are in the planning stages and 6 more are doable but difficult. The remaining 6 restrictions are probably permanent due to flooding, political, or historical issues.
