This bill amends existing subdivision regulations to enhance water supply management for new developments of four or more units. It introduces new subparagraphs to RSA 674:36, allowing local planning boards to request water supply studies to ensure adequate water availability for existing and future uses. The bill specifies that these studies are discretionary and do not apply to community water systems or large groundwater withdrawals regulated under RSA 485 and RSA 485-C. Additionally, it mandates the establishment of provisions to protect water-dependent natural resources and prescribes minimum testing requirements for on-lot private wells.

Furthermore, the bill clarifies the applicant's responsibilities regarding costs associated with subdivision applications. It allows planning boards to require applicants to cover expenses related to notifying abutters and to assess reasonable costs for local administrative or investigative needs for more complex applications. This new language aims to streamline the process while ensuring that water supply considerations are adequately addressed in the planning and zoning framework. The act will take effect 60 days after its passage.
