The following development standards shall apply to all U-4 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 five (5) acre lot subdivision which conforms to all Village regulations. The determination of permitted density shall not include any areas designated as flood plain or which are covered by an existing conservation easement.
(b) Open Space.
(1) Permanent open space shall be as set forth on the Final Approved Development Plan; provided, however, that the land area designated for permanent open space shall not be less than fifty-five percent (55%) of the total land area of the Conservation Development. Common 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 wetlands, woodlands, streams, lakes, historic features, and environmentally sensitive areas. Common open space shall be kept in its natural state except for generally accepted woodland and field management practices.
(2) The common 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 common open space within a U-4 Conservation Development District shall be contiguous unless otherwise specifically authorized by Village Council. It is preferred, but not required, that proposed common open space abut areas which have existing conservation easements.
(4) Open space conservation areas shall not be used for the location of common on-site wastewater disposal systems.
(5) Required setbacks and building separations within the disturbed or developed portion of a U-4 Conservation Development shall not be included in the calculation of permanent open space for the purposes of complying with the requirements of subsection (b)(1) hereof.
(c) Maximum Height. Buildings within a U-4 Conservation Development District shall comply with the maximum height provisions of Section 1155.05.
(d) Maximum Building Ground Coverage. The maximum building ground coverage by any individual dwelling unit shall not exceed four thousand five hundred (4,500) square feet.
(e) Access and Street Requirements.
(1) All streets constructed as part of a Conservation Development shall be private streets unless a public street is specifically authorized by the Village to provide for interconnection or to achieve some other public access purpose.
(2) Private streets within a Conservation Development District shall have eighteen (18) feet of asphalt pavement with berms. Private cul-de-sac streets shall be designed with sufficient turn around areas to adequately accommodate emergency vehicles and service vehicles such as snow plows and garbage trucks. Private streets shall be designed and constructed in accordance with the standards and specifications of the Village Engineer.
(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 clearly defined on the development plan.
(f) Setbacks and Separations. Building setbacks and separations shall be as established on the approved final development plan. In establishing said 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 the following:
(1) No building, structure, or parking area shall be located closer than two hundred (200) feet to the right-of-way line of an existing public or private street.
(2) No building, structure, lighting or parking area shall be located closer than one hundred (100) feet to any project boundary line.
(3) No building, structure, accessory use, landscape lighting, or parking area shall be located closer than seventy-five (75) feet to any protected watercourse within the Conservation Development or within 300 feet of the ChagrinRiver.
(4) No building or structure shall be located closer than fifty (50) feet from the edge of pavement or edge of easement of any private street constructed as part of the Conservation Development.
(5) The minimum distance between buildings shall be fifty (50) feet.
(6) No driveway or private road shall be constructed nearer than seventy-five (75) feet from any side or rear property line in a Conservation Development District. Where due to severe topographic or other special site conditions, the Planning and Zoning Commission authorized an exception to this setback requirement, the Commission may require installation of screening and buffering along the property line to mitigate potential impacts.
(7) The setback regulations contained herein shall not apply to structures such as boundary fences, entry gates, and gateposts.
(g) Architectural Design. Architectural treatments shall demonstrate a cohesive design concept which promotes compatibility among structures and reflects the character of the Village of Hunting Valley. All dwellings shall have a two (2) story design.
(h) Drainage. All Conservation Developments shall provide for storm water management and erosion and sedimentation control in accordance with the provisions of the Subdivision and Land Development Regulations. Plans for storm water management and erosion and sedimentation control shall be subject to the review and approval of the Village Engineer. No structural storm water management facilities shall be located within the open space conservation areas.
(i) Fire Protection. All Conservation Developments shall make provisions for fire protection which shall conform to the standards and specifications of the Village and Fire Chief.
(k) Impervious Surface. Not more than ten percent (10%) of the total area of any Conservation Development shall be covered with impervious surfaces. For purposes of this provision, impervious surface shall not include ponds.
(l) Gross Livable Floor Area. The gross livable floor area shall not be less than four thousand (4,000) square feet nor exceed a maximum of six thousand (6,000) square feet for any single-family dwelling unit, whether attached or detached. Gross livable floor area shall mean the sum of the total enclosed area of all floors of a building measured from the inside faces of exterior walls, excluding garages, basements, and uninhabitable attics.
