Committee tables broad zoning and density changes after technical and policy questions

The Committee on Housing and Economic Development tabled LD 2173 after an extended work session that walked through proposed amendments to affordable housing density, ADU provisions, utility definitions, flood and natural hazard references, and implementation timing.

Analysts presented a series of technical edits intended to clarify when a municipality may require minimum lot sizes, how to define a public sewer or water system, and whether an area is considered "served" if infrastructure merely traverses it en route to another growth area. Municipal planners and water‑utility representatives warned that a simple map‑based test is needed so towns are not forced to treat long transmission mains as evidence that intermediate areas are served and therefore subject to higher density requirements.

Mocha and municipal representatives also stressed the limits of municipal capacity and recommended pushing implementation dates into 2027, citing the time needed for rulemaking and for municipalities to prepare warrant/ordinance changes. Mocha said acceptable rulemaking timing is roughly four months if the agency has notice of required changes in advance; five months would be more realistic if changes take effect immediately and drafting cannot start in advance.

Other key open policy issues: whether the density multiplier in designated growth areas should be 105% or 130%, the duration of rate‑of‑growth caps (5 or 10 years), and minimum lot sizes outside growth areas (a stakeholder proposal would raise single‑lot minimums from 5,000 to 10,000 square feet and duplex lot minimums accordingly). Committee members asked analysts and stakeholders to return precise statutory text for those options.

The committee moved to table LD 2173 and directed staff to prepare clearer amendment language for the next meeting.
