In determining whether to grant a zone change to MFPRD District, the Town Board, in addition to its usual discretion in considering a change of zone, shall also consider the need for units for moderate-income families in the particular hamlet, the nature and extent to which the applicant intends to provide such units, the appropriateness of the site, environmental considerations, the proposed development design to accommodate such an increased density, and any potentially significant negative impacts to the school district or other special assessment district in which the proposed development is located. In addition, the Town Board shall find that the housing development is consistent with the recommendations of the Comprehensive Plan, will be beneficial, compatible and harmonious with the surrounding land uses and will not have a significant adverse impact upon the environment, the school district or upon other special assessment districts in which the site is located.
