HB 1588 establishes a process for cities and towns to create special assessment districts to fund infrastructure improvements (like roads, water, and sewer systems) directly tied to new housing developments. Municipalities can finance these projects through property assessments on benefiting parcels - collected over up to 20 years - without using general tax revenue. The bill also expands an existing state grant program to fund municipal infrastructure upgrades for new housing, with a $1 appropriation for fiscal year 2027. This directly affects municipalities planning new housing projects and property owners within designated districts who may face assessments based on their specific benefit from improvements.

SB 559 lowers the minimum speed limit on locally controlled roads from 25 mph to 20 mph in certain areas, including outside urban districts and within business or urban residential zones. Local authorities must base any speed limit reduction on engineering or traffic studies before implementing it. The bill does not require new funding or change existing enforcement, as it only modifies the minimum limit threshold in state law. This affects municipalities and town officials responsible for setting speed limits on local roads.

HB 1810 imposes a $4 fee per ton (or equivalent) on bulk road salt, road salt mix, and brine sold in New Hampshire to fund certified winter road maintenance practices. The fee is collected annually by bulk sellers (e.g., suppliers to municipalities, businesses, or state agencies) and deposited into a dedicated road salt mitigation fund. Sellers must file annual returns with the Department of Revenue Administration, maintain sales records for three years, and provide receipts showing the fee paid. This policy directly affects road salt bulk sellers and ensures funds support certified winter road maintenance programs across the state.
