(a) Intensity of Use. The maximum net residential density shall be twelve (12) dwelling units per acre of area devoted to residential use. Commercial and industrial uses shall not exceed eighty percent (80%) lot coverage by buildings, parking, and traffic circulation areas.
(b) Calculation of Density. The calculation of residential density shall include all land devoted to residential use, and shall further include easements for utilities except major facilities which do not serve individual dwellings. The calculation of residential density shall also include surface drainage facilities (detention areas and retention areas, if designed for recreational use or open space purposes in addition to stormwater management functions), recreation space, and other areas provided as common open space including land dedicated to public use except required street rights-of-way.
(c) Green Space. The minimum percentage of overall area devoted to green space shall be twenty percent (20%). This green space shall be either dedicated and maintained by the City of Heath or dedicated to a homeowner/property owners association (formed by the developer) at the City's discretion. If a homeowner/property owners association is required, then the developer shall submit the necessary documents to the City Planning Commission for review and approval.
(d) Arrangement of Areas. Areas of various densities within the PUD District, in addition to achieving these development standards, shall be so arranged and distributed so that the development of higher density shall be appropriately balanced by open space or low density development. When residential zoning districts, or other permitted uses are proposed, the development plan shall provide for building setbacks, landscaping and buffering along the common lot line of such zoning district boundary in order to accomplish an effective separation between the two areas. Transitions between commercial or industrial uses and adjacent residential uses shall be accomplished with screening, setbacks, and design elements sensitive to the adjacent uses as described in the City's Landscape and Open Space and Recreation Ordinances.
(e) Arrangement of Structures. The physical relationship of dwelling units and their minimum yard space shall be determined in accordance with the approved development plan. The burden shall be on the applicant to demonstrate that the proposed arrangement of structures will create a pleasing, functional, and safe environment.
(f) Traffic.
(1) The PUD Zoning Development Plan shall be accompanied by a preliminary analysis of traffic conditions which can be expected to result from the proposed development. Using existing data and formulas from the resources listed below, the analysis shall estimate the Average Daily Traffic (ADT), the peak hours of traffic, and distribution of the same to the existing and proposed street system, together with a brief analysis of improvements which may be necessary to accommodate the additional traffic. The applicant shall state and document assumptions made regarding the projected traffic figures. The following standard techniques and references, or other references which may be acceptable to the City:
A. Highway Capacity Manual (Special Report #87, 1965, National Academy of Sciences).
B. Transportation Research Circular #212.
C. "Trip Generation": Institute of Traffic Engineers (Current Edition). Traffic analysis shall be based on existing off-site conditions and known plans for the development of off-site areas.
(2) The purpose of this brief traffic analysis is to roughly gauge the impacts and needs generated by the proposed development. Traffic expected to be generated by the proposed development should not cause any tributary street or highway facility to operate below a level of service "C", as defined in the current edition of the "Highway Capacity Manual" (see above reference).
(g) Access. Whenever multiple structures to be located in a PUD District are located on a collector street or arterial street, as defined by the City Thoroughfare Plan, access onto the collector or arterial shall be via interior local streets or marginal access (frontage) roads or other means of access control as approved in the PUD development plan. All uses within the PUD shall derive their access from the interior streets within the PUD, unless specific exemptions are made as a part of the approved final Zoning Development Plan.
(h) Parking. Off-street parking, loading, and service areas shall be provided and arranged in accordance with other City Ordinances.
(i) Sidewalks. Safe and convenient sidewalks and other pedestrian circulation systems shall be provided within all PUD residential and commercial areas. Sidewalks shall be no less than four feet wide in residential areas, not less than six feet wide in other districts, and located one foot outside the right-of-way line of the abutting public street. When deemed necessary by the Planning Commission, grade separated crossings shall be provided in the vicinity of schools, playgrounds, shopping areas, or other pedestrian traffic generators. Proposed ownership and responsibility for the pedestrian ways shall be indicated in the PUD Zoning Development Plan. Sidewalks and other pedestrian ways shall meet the minimum construction standards of the Subdivision Regulations.
(j) Stormwater Drainage. Drainage and runoff from the proposed development shall not cause property damage. Stormwater management techniques shall be designed in conformance with the requirements of the Subdivision Regulations.
(k) Sewage Disposal and Water Supply. Information regarding the adequacy of sewage disposal and water supply to be utilized shall be included in the preliminary zoning development text. Letters affirming adequate capacity from pertinent local, State and, if applicable, private
agencies shall be submitted.
(l) Architectural Design.
(1) Architectural renderings of typical structures and improvements sufficient to relay the basic architectural intent of the proposed improvements shall indicate general exterior design and potential materials. All buildings shall be constructed with materials compatible with the surrounding environment, and consistent with the design character for each building on all sides.
(2) When available, private deed restrictions pertaining to design character and location of buildings should be included for review along with the Zoning Development Plan.
(3) No parcel or lot shall have constructed thereon any building which shall have a ground level floor coverage of greater than fifty percent (50%) of the lot or parcel upon which such building is constructed.
(4) Building height shall not exceed thirty-five (35) feet unless otherwise indicated and approved as a part of the PUD Zoning Development Plan as appropriate to the specific site and neighborhood character.
(5) All outside storage trash collection sites and loading areas shall be screened to prevent visibility from any adjacent street or lot.
(6) All utilities shall be placed underground.
(7) All below ground storage facilities not under the ground floor of structures shall be illustrated on the PUD Zoning Development Plan.
(m) Nuisances. All land uses within the PUD District shall be operated so that all performance requirements of the City Zoning Code are maintained, including:
(1) Smoke. No smoke from an industrial or commercial process shall be emitted from any structure in the PUD.
(2) Odor. No use shall emit odorous gases or other odorous matter in such quantities as to be detectable at any point on or beyond the PUD boundary.
(3) Noise. No commercial, service, or industrial use shall emit greater than fifty-five decibels at the lot line.
(n) Graphics. The PUD Zoning Development Plan shall establish details illustrating the criterion proposed for a unified graphics theme for the proposed PUD. At a minimum, all graphics shall conform to Chapter 1187 of the Building Code. All graphics permits within a PUD District shall be approved by the City Graphics Commission. For purposes of the PUD Zoning Development Plan, the applicant shall describe the types, limitations, and controls to be utilized along with descriptions, examples, or sufficient detained information on the proposed graphics to be utilized within the PUD District. In no case shall PUD graphic requirements be less restrictive than the current City sign ordinance.
