There is hereby established an Affordable Housing Zone-2 (AHOZ-2) permitting multi-family (apartment) dwellings in a portion of the L-I Zone as depicted on the revised Zoning Map and further described as follows: The AHOZ-2 Zone encompasses an area shown on the Edison Township Tax Map as Block 396, Lot 5 (formerly Block 396, Lots 5 and 7). The purpose of this zone is to permit multi-family dwellings (apartments) at the density hereinafter described provided that a substantial percentage of these units shall be deed restricted for occupancy by and affordability to low and moderate income households. Substantial percentage is defined as: twenty (20%) percent of the total housing units constructed if the low and moderate income units are for sale and fifteen (15%) percent if the low and moderate income units are rentals. For any development containing both rental and for sale units, the percentage of units designated for low and moderate income households shall correspond to the percentages given above for each unit type. For example, a development consisting of one hundred (100) rental units and one hundred (100) for sale units shall have twenty (20) for sale dwelling units set aside for low and moderate income households and fifteen (15) rental dwelling units for low and moderate income households.
