Such conditionally zoned areas shall be designated as "Contract Zone Overlay Districts" on the Official Zoning Map. The intent of regulations affecting the use of land and buildings within this overlay district is to mitigate potential adverse effects upon adjacent properties and the Town by providing a mechanism whereby specific conditions may be added to the granting of a change in zoning. A zone change to CZO may only be granted if the application of the zoning to the property in question meets the same standards of consistency with the Town's Comprehensive Plan as any other zone change enacted under the provisions of this chapter.

The locations of district boundary lines illustrated on the Official Zoning Map are interpreted as follows:

Any change to the location of a district boundary line on the Official Zoning Map must be approved by the Town Council. Any change to a shoreland district boundary must be also approved in accordance with § 100-5.
