Extensive testimony opposes broad bill to constrain local zoning; municipal leaders warn of legal and infrastructure conflicts

Senator Keith Murphy framed SB 170 as a package of reforms aimed at removing barriers to housing that can arise in local zoning — provisions discussed included limits on frontage and setback requirements, restrictions on local requirements for septic and well siting, limits on maximum road lengths in subdivision rules, and tighter deadlines for planning board review.

The bill drew extensive opposition from municipal leaders, the New Hampshire Municipal Association (NHMA), and planning officials who told the committee the proposal is too broad, contains statutory and technical conflicts, and would disrupt tools towns already use to shape development and protect natural resources. Brody (Bridal) Deshaies of NHMA said the package “would mandate unworkable planning and development requirements on towns and cities and big‑government mandates, which undermine local control and the will of voters in every municipality throughout the Granite State.”

Specific objections included: - Conflicts with existing statutes and regulations (for example, state shoreland and wetland protections and RSA provisions that already permit municipalities to set stricter protections). - Undermining cluster/conservation subdivision tools by allowing utilities and septic systems to be sited in protected open space, which would defeat the policy aim of conserving land. - Practical review timing problems: the bill would require planning/technical comments to be submitted and resolved in extremely short windows (for example, “one‑bite” provisions that limit iterative review), but third‑party review and technical coordination often require weeks.

Local officials also said a blanket 50‑foot limit on frontage or a maximum setback cap would be incompatible in many parts of the state — urban lots may be narrower while rural towns may need larger setbacks for wellfields and septic systems. Tim Thompson, Concord’s assistant community development director, urged the committee to remove or reconsider the 50‑foot frontage mandate and not to impose a three‑day turnaround for technical plan revisions.

Developers and housing advocates supporting the bill argued local permitting delays and ad‑hoc conditions can block otherwise‑sound projects. Matt Mayberry of the NH Home Builders Association said the “bite at the apple” reform would limit open‑ended, iterative revision cycles that developers experience with planning boards. Housing advocates said the measure intends to reduce delay and regulatory uncertainty.

Ending: Committee members heard detailed procedural and legal objections from planning professionals and municipal leaders and across the room positions from builders and housing advocates. Stakeholders asked the committee to either table the bill for study or substantially rewrite the text to avoid statutory conflicts and unintended effects on conservation, water protection and municipal finance.
