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 dwelling unit per 60,000 square feet. The determination of permitted density shall not include any areas which are covered by an existing conservation easement. The area of existing right-of-way adjacent to or within the conservation development area shall not be included in density calculations.
(b) Restricted Open Space.
(1) Restricted open space shall be as set forth on the final approved development plan provided, however, that the land area designated for restricted open space shall not be less than forty-five percent of the total land area of the Conservation Development District. Restricted open space shall be located and designed to be integrally related to the overall design of the development and to conserve and protect significant natural features such as floodplains, steep slopes, wetlands, woodlands, streams, lakes, historic features, and other environmentally sensitive areas. Restricted open space shall be kept in its natural state except for generally accepted woodland and field management practices and unless authorized in an approved development plan.
(2) The restricted open space shall be made subject to a perpetual conservation easement in a form approved by the Village in favor of an organization or agency acceptable to the Village. Conservation easements shall include the Village as third party beneficiary of the terms of the easement with the right, but no obligation, to enforce the provisions of the easement.
(3) All of the restricted open space within a Conservation Development District shall be contiguous unless otherwise specifically authorized by Village Council. It is preferred that proposed restricted open space abut areas that have existing conservation easements.
(4) Restricted open space shall not be used for the location of on-site wastewater disposal systems or structural stormwater management practices.
(5) No portion of any privately owned building lot within a Conservation Development District shall be included in the calculation of restricted open space for the purposes of complying with the requirements of paragraph (1) above.
(c) Maximum Height. Buildings shall comply with the provisions of Single-Family Residential District as applicable.
(d) Maximum Building Ground Coverage. The maximum coverage, including the main dwelling and all accessory buildings shall not exceed 4,000 square feet.
(e) Access and Street Requirements.
(1) All streets, public or private, shall meet Village standards in place at the time of application and shall be designed as approved by the Village Engineer.
(2) Each dwelling unit shall have access to a street internal to the Conservation Development District in a manner defined on the final development plan.
(f) Setbacks and Separations. 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:
(1) No building, structure, or parking area shall be located closer than 100 feet to the right-of-way line of an existing public street.
(2) No building, structure, lighting or parking area shall be located closer than 100 feet to any development plan boundary line.
(3) Buildings and accessory structures in Conservation Development Districts shall be located no closer than fifty feet from the edge of pavement within the development.
(4) The minimum distance between dwelling units shall be fifty feet.
(5) The setback and separation codes contained herein shall not apply to structures such as boundary fences, driveways, entry gates, and gateposts.
(g) Architectural Design. Architectural treatments shall demonstrate a cohesive design concept that promotes compatibility among buildings and structures and reflects the character of the Village.
(h) Stormwater Management. All Conservation Development Districts shall provide for stormwater management and erosion and sediment control in accordance with the provisions of the Subdivision Regulations, Chapters 1448 and 1450 of these Codified Ordinances and any other applicable Village regulation. Plans for stormwater management and erosion and sediment control shall be subject to the review and approval of the Village Engineer. No structural stormwater management facilities shall be located within the restricted open space.
(i) Fire Protection. All Conservation Development Districts shall make provisions for fire protection that shall conform to the standards and specifications of the Village.
(j) Lighting. Lighting in a Conservation Development District, if proposed, shall be defined on the final development plan.
(k) Impervious Cover. Not more than ten percent of the total area of any Conservation Development District shall be impervious. For purposes of this Code, impervious cover shall not include ponds.
