Allows adoption of subdivision regulations requiring water supply studies, determination of adequate water quantity, and minimum on-lot private well testing for subdivisions of 4 or more units, and clarifies the applicant's duty to pay associated costs.
allowing subdivision regulations concerning water supply.
Our water table is not infinite. It is wise to test water supply prior to approving developments over 4 units, to ensure there is sufficient water for the new development and for the structures already relying on the local water supplies.
Dear Members of the Housing Committee, I write in strong support of HB 1120 and respectfully urge the committee to recommend the bill as Ought to Pass. HB 1120 addresses a critical but often overlooked component of housing development: long-term water supply adequacy. By clarifying that municipalities may adopt subdivision regulations requiring water supply studies and testing for certain residential developments, this bill strengthens responsible planning while supporting sustainable housing growth. From a technical planning and housing-policy perspective, water availability is foundational infrastructure. Housing that lacks a reliable water supply is not viable housing. HB 1120 provides municipalities with the authority—at their discretion—to ensure that new subdivisions relying on private wells do not compromise public health, existing users, or future development potential. This is especially important in areas without access to public water systems, where cumulative impacts on groundwater can be significant. Importantly, HB 1120 is an enabling bill, not a mandate. It does not impose uniform statewide requirements or prohibit development. Instead, it allows local planning boards to tailor subdivision regulations to local hydrogeologic conditions, consistent with existing authority under RSA 674. This respect for local control, combined with statutory clarity, is essential for effective land-use governance. HB 1120 also supports housing production by improving predictability and reducing risk. Clear standards for water adequacy help applicants understand expectations early in the process, reduce the likelihood of failed or contested approvals, and prevent costly post-construction problems that can undermine both housing supply and municipal trust. From a fiscal and policy standpoint, the bill is sound. It places the cost of required studies on the applicant, not local taxpayers, and helps avoid downstream costs associated with dry wells, emergency water delivery, or public intervention after homes are built. As New Hampshire works to expand housing opportunities, it is critical that new development be durable, safe, and supported by adequate infrastructure. HB 1120 advances that goal in a measured, technically appropriate manner. For these reasons, I respectfully urge the Housing Committee to vote Ought to Pass on HB 1120. Thank you for your consideration and your continued work on housing and land-use policy. Respectfully, David Preece State Representative, Hillsborough District 17 New Hampshire House of Representatives
