In 2015, NHCP provided grant funding to The Nature Conservancy, in partnership with the town of Newmarket, to conduct topographic survey, hydrological and hydraulic analysis, geotechnical analysis and alternative analysis to develop engineering design drawings for the replacement of a severely undersized and perched culvert where Bay Road crosses Lubberland Creek in Newmarket. Lubberland Creek Culvert Replacement, Newmarket Results of the project are available in a variety of formats: The Resilient Tidal Crossings NH Project was designed to better enable community officials and road managers to enact the strategic repair/replacement of tidal crossing infrastructure and to identify high priority restoration and conservation opportunities at tidal crossing sites. Tidal crossing assessment data were used to rank and prioritize sites based on structure condition, flood risk and ecosystem health. In 2018, the NHDES Coastal Program and its partners assessed all known tidal crossings in New Hampshire's 17 coastal communities in accordance with the New Hampshire Tidal Crossing Assessment Protocol. When properly designed and maintained, tidal crossings can balance the needs of people and the environment by providing a functional, reliable and safe transportation network that supports the continuous movement of people, goods, and services across coastal communities while allowing adequate tidal flow to maintain healthy tidal marshes. A tidal stream crossing (tidal crossing) is a bridge or culvert that conveys tidal flow below a traveled way, such as a road, pedestrian path, or railroad.
