The following development standards shall apply to all Conservation Development Districts:
(a) Density of Dwelling Units. The maximum density of dwelling units shall be as set forth on the approved Development Plan. In no case shall the density be greater than the lesser of one (1) dwelling unit per five (5) acres or the permitted density determined by a Yield Plan for a conventional lot subdivision that conforms to all Village codes. The Yield Plan shall be prepared and reviewed in accordance with the requirements and process detailed in Section 1160.16.

(3) Each dwelling unit shall have access to a public street or to a private street internal to the Conservation Development District in a manner approved by the Village and said access shall be defined on the Development Plan.
(f) Setbacks and Separations: If developed as a condominium development, dwelling units within a Conservation Development District shall be a part of a condominium arrangement in accordance with Chapter 5311 of the Ohio Revised Code. For all developments, building setbacks and separations shall be as established on the approved Development Plan. In establishing said setbacks and separations, Village Council shall consider the spacing necessary for adequate visual and acoustical privacy, adequate light and air, fire and emergency access, building configurations, energy-efficient siting, and the relationships of building sites to circulation patterns. In no instance shall the established setbacks and/or separations be less than those required by the underlying zoning or the following, whichever is more restrictive:
