General provisions. Planned development districts shall be considered as a single parcel for the purpose of applying the regulations for yard dimensions specified in Area, Frontage, Bulk, Height and Setback Requirements for Zoning Districts. (A schedule of area, frontage, bulk, height and setback requirements for zoning districts is located at the end of this chapter.) Individual buildings and structures within such district need not conform to the regulations of Area, Frontage, Bulk, Height and Setback Requirements for Zoning Districts, provided that any variation from such regulations shall not be contrary to the intent of this chapter. The requirements for off-street parking, loading and unloading, screening and other transitional measures shall be as specified in this chapter. Such requirements are minimum specifications and may be more restrictive in accordance with the standards set forth elsewhere in this section. All requirements generally applicable to districts within the Town are applicable to zoning approved through PDD legislation, unless otherwise provided within that PDD legislation.
