Affordable housing overlay districts are established in order to achieve the general goals as stated in § 34-2, as well as to create an opportunity for the construction of inclusionary housing in the Borough of Milltown. All affordable housing units constructed within these overlay districts shall conform to the applicable provisions in § 34-18, Affordable Housing. The uses contemplated in an overlay zone shall be permitted in addition to the uses permitted in the underlying zone. Bulk and other standards set forth in the overlay zone shall only apply to uses specifically subject to the overlay zone, and not to uses governed by the underlying zone.
