The subdivision regulation, however, does not control or apply to the operative terms of the Zoning Ordinance. Further, a determination that the lease does or does not create a new lot will resolve only the question of whether AT & T's application violates article 4.4.2(C) of the zoning ordinance; the operation of article 8.8.1(d)(4) raises a different question requiring a separate analysis.

When interpreting an ordinance, we look first to the plain meaning of the language in the ordinance and give any undefined terms their common and generally accepted meaning unless the context clearly indicates otherwise.

In contrast to the deferential review accorded the Planning Board's factual findings and conclusions, its interpretation of the ordinance to which those facts are applied presents a question of law subject to de novo review. JPP, LLC v. Town of Gouldsboro, 2008 ME 194, ¶ 8, 961 A.2d 1103, 1105. [¶ 34] In its 2005 written decision, the Planning Board recognized its obligation to apply the land use ordinance impartially, and identified the applicable provision as section 5(D), governing omitted uses:

Courts must construe the language at issue so as to give effect to the ordinance's objectives and whole text. JPP, LLC v. Town of Gouldsboro, 2008 ME 194, ¶ 8, 961 A.2d 1103 (quotation and citation omitted).
