relative to a flood resilience section in municipal master plans.
HB 1468 allows New Hampshire municipalities to voluntarily include flood resilience planning in their master plans, without imposing new state mandates or costs. The bill amends state law to require municipalities to identify flood risks and propose mitigation measures in their natural hazards sections (Section 2), and adds an optional coastal/inland flood resilience section addressing storm surge, riverine flooding, erosion, and infrastructure protection (Section 3). It also expands state housing planning grants to cover flood hazard mitigation and related land use updates. Municipalities may choose whether to adopt these provisions, with the law taking effect 60 days after passage.
