Pownal Planning Board advances broad zoning revisions, from non‑conforming lots to ADUs and mobile‑home standards

The Town of Pownal Planning Board on Feb. 18 continued a multi‑section review of proposed zoning ordinance revisions intended to update local requirements, clarify ambiguous language, and respond to recent state statutory changes.

Planning consultant Isabelle Lee reviewed changes addressing three common non‑conforming‑lot scenarios: (1) a single non‑conforming lot of record that does not meet dimensional standards but may be built upon without a variance under clarified procedures; (2) contiguous non‑conforming lots under single ownership that are commonly combined to eliminate non‑conformity (a more controversial proposal the Board debated); and (3) rare eminent‑domain situations that require special handling. Board members expressed concern about automatically combining lots at adoption and preferred triggering combination when an owner seeks to build.

The Board discussed frontage definitions and the town’s historical practice of reserving narrow right‑of‑way strips (for example, prior practice creating 60‑foot strips) to preserve future road access. Several members argued for explicit limits on creating new non‑conforming lots; consultant Lee recommended defining frontage in terms of legal access to a public street or an approved private road, rather than hard‑coding numeric frontage values in a single definition to avoid scattered changes across the ordinance.

Net developable area language, including a 50‑foot rule for thin strips of land between boundaries, drew examples of past subdivisions and flag‑lot configurations that complicated density calculations. The Board asked staff and the consultant to clarify how existing lots and historical decisions will be treated under new language.

Members also debated height and farm‑building rules. The draft treats structures over 35 feet as potentially subject to special review and discussed farm buildings as a separate defined term; the Board asked the consultant to research customary municipal approaches and to propose a clear definition and, if appropriate, square‑footage thresholds to distinguish typical farm buildings from industrial‑scale agricultural structures.

On accessory dwelling units (ADUs), Isabelle noted recent State statutory changes that limit some municipal controls; she advised caution and recommended legal review because the town may not be able to require single ownership or other previously used controls for ADUs. The Board agreed to send the ADU language to the town attorney for clarification.

The proposed mobile‑home park overlay and related utility, septic and emergency‑power performance standards drew detailed discussion. Deputy CEO Bill Schmidt summarized performance standards derived from state authorities (references in the meeting included the Manufactured Housing Board and Maine CDC Chapter 231): minimum design capacities, reserve leachfields, 24‑hour interruption design criteria with allowance for alternative engineering compliance, emergency contact lists, and enforcement mechanisms. The Board emphasized that local language should be aligned with state rules and be performance‑based rather than prescriptive where state law governs.

Isabelle flagged several provisions for legal review — notably the ADU language and spacing/road‑spacing rules meant to preserve rural character — and recommended explicitly tying spacing limits to the town’s Comprehensive Plan to reduce appeal risk. The Board set a schedule to refine draft language, send select sections to counsel, hold a public meeting, and incorporate revisions before warrant deadlines and public hearings in April.
