The general development plan shall set forth the permitted number of dwelling units, the amount of nonresidential floor space, the residential density and the nonresidential floor area ratio for the planned development, in its entirety, according to a schedule which sets forth the timing of the various sections of the development. The general development plan and the site plan shall conform to the following general design standards:
A. Land use standards.
(1) Lots and structures shall be laid out to the greatest extent feasible in a manner to preserve the natural landscape of the site, including the scenic vistas as seen from the public roadways.
(2) Lots and structures shall be laid out to the greatest extent feasible in a manner to meet the energy conservation standards contained in this chapter.
(3) Lots and residential structures shall be arranged to maximize privacy for residents and neighbors in the surrounding community and to minimize conflict with abutting uses and exposure to nuisance factors such as lighting glare and noise.
(4) The safety of the residents shall be considered in project design particularly with regard to the elements of circulation, landscaping, lighting and the location of lots and structures.
(5) Residential development shall be evaluated in accordance with the standards for the type of residential units proposed such as attached single-family, detached single-family, and multifamily housing types.
B. Circulation standards.
(1) A traffic impact study shall be submitted with the application for development as required by this chapter.
(2) Traffic facilities affording general access to and circulation within the development may be developed as public streets or private roads. However, access must be perpetually available to residents and emergency vehicles.
(3) Streets contained within the development shall conform with the design standards contained in this chapter. The City has the right to refuse to accept streets proposed as public streets if they do not meet these standards.
(4) At least one public street or private road access shall be permitted for each development unless the approving authority finds that additional access is required because of the characteristics of the adjacent streets. In no case shall developments have primary access through abutting properties unless the property is completely landlocked. Secondary access may be permitted off tract only after the affected residents have been notified and a public hearing has been held.
(5) The approving authority may require whatever off-tract improvements are necessary to accommodate projected traffic impacts based on the development's proportional share of additional traffic to ensure safe vehicular and pedestrian circulation.
(6) If a shared access street or road is developed to serve two or more developments, or a single development with two or more owners, appropriate dedication or easement documents must be submitted to ensure perpetual access to each development.
(7) Clear sight triangles shall be required where streets intersect dedicated public streets. A distance of 300 feet shall be maintained clear of obstructions measured from the stop sign of the streets within the development.
(8) Principal vehicular access points shall be designed to encourage smooth traffic flow with controlled turning movements and minimum hazards to vehicular and pedestrian traffic. Merging and turnout lanes or traffic dividers shall be required where existing or anticipated heavy traffic flows indicate need. Minor streets shall not be directly connected with other streets by internal driveways or roads in such a manner as to encourage the use of minor streets by substantial amounts of through traffic.
(9) Access for bicyclists and pedestrians entering or leaving the site shall be made by convenient and safe routes. Such access need not be adjacent or limited to the vicinity of access points for motor vehicles. Sidewalks shall be constructed for pedestrian access. Bicycle and pedestrian paths within the development shall be encouraged to be separated from motor vehicle traffic to the greatest extent feasible. Bicycle paths shall be interconnected with the existing or proposed bicycle circulation system for the City.
(10) Where there are bicycle or pedestrian paths from within the development to a street at its edge, no material impediment to visibility shall be created.
(11) Curbing shall be required along all public streets and the streets within the development in accordance with standards contained in this chapter.
(12) Concrete sidewalks shall be required along all dedicated public streets and the streets within the development in accordance with standards contained in this chapter. Sidewalks shall be required to connect all residential units to parking areas. Paths intended for recreational use may be constructed of materials other than concrete.
(13) Off-street parking lots and spaces exposed to public streets or adjacent to one- and two-family residential neighborhoods shall be bermed or screened by walls or other solid materials in addition to landscaping.
(14) Resident spaces for one- and two-family residential structures may be provided by driveways allowing a maximum of two stacked cars. Garages may be counted toward meeting the parking requirements only if the management organization prohibits their conversion to living space.
C. Open space standards.
(1) Open space shall include an area of land or water essentially unimproved and reserved for public or private use or enjoyment; provided, however, that the land may be improved with those structures and improvements that are designed to be incidental to the natural openness of the land.
(2) Common open space shall include an area of land reserved for the use or enjoyment of the owners and residents of the development. Such land may contain complementary structures and improvements as are appropriate and necessary for the use or enjoyment of the owners and residents of the development, including active and passive recreational uses.
(3) The common open space shall be considered part of the open space for the purpose of fulfilling the open space requirements contained in this article.
(4) Wherever feasible, the common open space shall connect to existing conservation lands, historic sites, parks or recreational lands, or, as applicable, lands proposed for these uses in the Master Plan.
D. Local service and utility standards.
(1) The development shall be serviced by the municipal wastewater collection and treatment system. The developer shall design and construct a common system on site to tie into the municipal system.
(2) The development shall be serviced by the municipal water system. The developer shall design and construct a common system on site to tie into the municipal system.
(3) All electric, telephone, television and other communication facilities, both main and service lines, shall be provided by underground wiring within easements or dedicated public rights-of-way and installed in accordance with the prevailing standards and practices of the utility or other companies providing such services. Overhead lines may be permitted as an exception by the Planning Board in areas of severe geological conditions. The placement and alignment of the poles shall be designed to lessen the visual impact of overhead lines.
(4) The developer shall provide adequate and efficient methods for handling solid waste disposal, including materials that are required to be recycled pursuant to municipal ordinance.
E. Stormwater management standards.
(1) Stormwater management systems shall emphasize a natural drainage strategy as opposed to an engineered drainage strategy. The applicability of a natural drainage strategy depends on such factors as site storage capacity, open channel hydraulic capacity and maintenance needs and resources.
(2) Where natural drainage strategies are inadequate to accommodate stormwater management for the site, detention facilities and other stormwater facilities shall be designed and engineered according to the best available technology.
(3) When the site contains or is adjacent to natural lakes, ponds, rivers, streams or wetlands, the runoff collection system shall be designed to prevent watershed runoff into these areas to the greatest extent feasible.
(4) A stormwater management system shall be designed and engineered to prevent an increase in nonpoint pollution to the greatest extent feasible.
F. Environmental and visual standards.
(1) An environmental impact study shall be submitted as required by this chapter. It shall include an inventory and general description of the natural attributes of the site, including an inventory and general description of the soils, topography, vegetation, geology and surface hydrology on the site.
(2) The design and placement of lots and structures shall be made in a manner to integrate the development attractively and harmoniously with its surroundings to enhance the natural features of the site.
(3) Careful attention shall be given to the design and quality of all structures and site amenities so that they are compatible within the development and compatible with the natural landscape.
(4) Adequate and functional lighting shall be located so as to provide maximum aesthetics and safety while minimizing glare and nuisance.
(5) Special natural features such as lakes, streams, wetlands and woodlands as well as scenic views shall be preserved to the greatest extent feasible.
(6) Existing topography and natural drainage patterns shall be retained to the maximum extent feasible.
(7) Grading and construction plans shall comply with applicable soil erosion and sediment control regulations.
(8) Fences, walls or hedges shall be utilized at the edges of the site where buffers or screening are needed to protect the residents from undesirable views, lighting glare, noise or other off-tract influences which are undesirable.
(9) Off-street parking areas, service areas and areas for the collection and storage of garbage and refuse shall be screened by a visual barrier of at least six feet in height.
