Authority and purpose. Pursuant to 30-A M.R.S.A. § 4352(8), conditional or contract zoning is hereby authorized for development where, for reasons such as the unusual nature or unique location of the development proposed, the Town Council finds it necessary or appropriate to impose, by agreement with the property owner or otherwise, certain conditions or restrictions not generally applicable to other properties similarly zoned. All contract or conditional zoning under this section shall establish rezoned areas which are compatible with the existing and permitted uses within the original zones. Nothing in this section shall authorize a rezoning, or an agreement to change or retain a zone, which is inconsistent with the Town's Comprehensive Plan.
