Any site should be developed in a manner that is consistent with the intent and purpose of a traditional neighborhood development concept plan, such as that shown in the attached drawing labeled "Concept Plan for Block 82, Lots 1.2, 2.2, 16.2, 30, 32, 34, 36 & 38," which could apply to an existing five-acre tract commonly known as the EFCO site. This concept plan provides for general locations for access from Central Avenue, street layout, block and lot configuration, alleyways and the location of a common open space and a neighborhood green.
