Notwithstanding the fact that Class A Regional Project approval may have been granted by the Adirondack Park Agency after a finding by that body that the project would comply with all provisions of this chapter, it must be recognized that reasonable bodies may differ. Therefore, where the Town Planning Board finds that the project would have an undue adverse impact upon the natural, scenic, aesthetic, ecological, wildlife, historic, recreational or open space resources of the Town or upon the ability of the Town to provide supporting facilities and services made necessary by the project, taking into account the commercial, industrial, residential, recreational or other benefits that might be derived from the project, or that the project would otherwise not be approvable under this chapter, the Board may disapprove the project, irrespective of any Agency approval. In such case, the reasons for Planning Board disapproval shall be specified in writing.
