[Amended 12-17-2019]
(3) 
Special permit.

(2)

B. 
Upon determination that the property in its existing condition or any alternate conforming development does not yield a reasonable economic return, the Planning Board shall proceed to investigate the minimum alternate solutions which might be authorized by a special permit which would modify the zoning regulations of the underlying district or the overlay district. In addition, the Planning Board may require special techniques or policies or economic aid or other incentive which may assure a reasonable economic return. However, such alternate solutions must be in keeping with the spirit and intent of the findings in the definitive statement incorporated in the subject Planned Landmark Preservation Overlay District. The findings of such investigation and the resulting recommendation shall be promptly transmitted to the applicant and to the Town Board.
C. 
When the Town Board has completed its review of the Planning Board's recommendations and made such modifications as it sees fit, it shall transmit its determination to the applicant. The applicant may either accept or reject these recommendations.

If the applicant shall reject the recommendations, the Town Board may deny permission to demolish, alter or reconstruct for a period of 90 days from the date of such notification. During such time the Town Board may seek further alternate solutions or act to condemn the subject property.
