The goal of the Two-Family Residential Overlay District is to allow developers to have the option of developing, or redeveloping, designated lots for two-family dwellings, while also retaining the developers' option to develop, or redevelop, in accordance with the underlying zone district. As such, the Two-Family Residential Overlay District designation does not replace the underlying land use designation for these parcels, nor does it replace any other overlay designations imposed on these parcels; it merely supplements it.
