The whole parcel or parcels where the housing development will occur. If the development is to occur over multiple parcels, the parcels must be contiguous (i.e., a parcel may be separated by a road). Only parcels where the housing development is to occur can be included in the Housing Development Site, unless contiguous parcels are under common ownership and share a School Property Account Number (SPAN), in which case they must also be included. Housing Development Sites must be formally designated by the municipality (24 V.S.A. § 1908) and approved by VEPC. Housing Development Site boundaries define the area within which the original taxable value is established, and tax increment is generated. Once established, the boundaries of the Housing Development Site shall not change.
