A nonconforming bar, tavern, or nightclub may be subject to compulsory termination by the Chief Building Inspector (after approval from the Town Board by resolution), when it is found detrimental to the conservation of the value of future development of surrounding land or improvements or is tending to deteriorate or blight the surrounding neighborhood. "Compulsory termination" shall mean that, after a period established by the Chief Building Inspector of up to but not exceeding 10 years, the bar, tavern, or nightclub shall be fully and finally terminated. The purpose of said period is to enable the owner and, where applicable, the operator or tenant (collectively the "owner") to amortize their respective interests in the subject property, which shall not exceed, in the aggregate, the difference between the value of the land and improvements for its current nonconforming use and its value for a conforming use, plus such other reasonable costs as the termination may cause. In determining such values, the Chief Building Inspector shall utilize the services of accredited appraisers and, in determining the length of such period ("amortization period"), the Chief Building Inspector shall employ a rate of amortization consistent with reasonable economic practice.
