relative to shoreland septic systems.

This bill updates regulations for septic systems on waterfront properties in New Hampshire by clarifying that "developed waterfront" includes land within 250 feet of fresh water, coastal waters, or rivers. It requires a more detailed four-part site assessment study for these properties, which must include specific data on soil, slope, and water tables, along with a professional evaluation of the existing system. The legislation also mandates that if a designer finds a septic system is failing during an assessment, the system must be replaced before the property is sold. Additionally, the bill preserves the ability of local governments to enforce stricter septic standards than those set by the state. These changes take effect on September 1, 2024.
