9-11-12: RESIDENTIAL PLANNED UNIT DEVELOPMENT:
   A.   Purpose: The unique and substantially different character of residential planned unit developments require their administrative processing as a "special use" in this title. Residential planned unit developments are more complex and of a different character than other special uses, requiring the establishment herein of specific and additional procedures, standards and exceptions to govern the recommendations of the village board. The purpose of the residential planned unit development is to encourage and allow more creative and imaginative design for land developments than is possible under conventional district zoning regulations. The residential planned unit development also provides for more efficient use of the land, and thus results in more economical land development. Preservation of natural site qualities, better amenities, more open space, and a high quality project are the normal results of the planned unit development process.
The following objectives may be obtained through the use of the residential planned unit development procedure:
      1.   To permit a greater choice in types of environment available to the public by allowing a development that would not be possible under the strict application of the other sections of this title.
      2.   To promote a creative approach to the use of land and related physical facilities that results in better design and development, with the inclusion of aesthetic amenities.
      3.   To combine and coordinate architectural styles, landscape design, building forms and building relationships with a possible mixing of different uses in an innovative design.
      4.   To enhance the appearance of neighborhoods through the provision of underground utilities, and the preservation of natural vegetation, topographic and geological features and environmentally appropriate features.
      5.   To provide for the prevention and/or control of soil erosion, surface flooding and the preservation of subsurface water.
      6.   To create a method for the preservation of common open space for the continuous use and enjoyment of the residents and users of the development.
      7.   To provide for more usable and suitably located recreational facilities, schools and other public and private facilities.
      8.   To promote the more efficient use of the land resulting in more economic networks of utilities, circulation and other facilities.
      9.   To create a method for the permanent preservation of architectural, natural and/or historic landmarks.
      10.   To encourage land use which promotes the public health, safety, comfort, morals and welfare.
   B.   Minimum Area: A minimum site of one hundred twenty five (125) acres shall be required for all residential planned unit developments.
   C.   Uses Allowed: The uses which may be permitted under a residential planned unit development include those listed as permanent uses or special uses in the underlying district(s).
   D.   Density: The density of a residential planned unit development shall not exceed the amount or number of dwelling units allowed under the requirements of the underlying zoning district. Except, density bonuses may be granted for the presence of exceptional design features in a Residential Planned Unit Development. The eligible design features are:
      1.   Adjacent Major Roads: Where the development is abutting one or more of the following major roads: Lake-Cook Road, Milwaukee Road or Saunders Road (south of Deerfield Road), an increase of up to forty percent (40%).
      2.   Adjacent Permanent Open Space: Where the development is adjacent directly to permanently reserved open areas of green space in contiguous tracts exceeding five hundred (500) aggregate acres, an increase up to twenty five percent (25%) of the base residential density may be granted.
      3.   Excellence in Site Planning: Where the project site plan exhibits exceptional adherence to the purposes and objectives of this Chapter, an increase of up to fifty percent (50%) of the base residential density may be granted. In addition to the standards found in Section 10-9-8 of this Chapter, the following standards shall be used to measure site plans for excellence:
         a.   The natural topographic and landscape features of the site shall be incorporated into the development wherever possible.
         b.   The site shall not be so overcrowded as to cause unbalanced relationships of building to open space. Additional landscaped areas beyond the minimum required shall be encouraged, preferably exhibiting continuity throughout the development.
         c.   Open space areas shall not be unduly isolated from one another by unrelated obstructions such as buildings and paved vehicular areas, but rather, shall be linked by open space corridors of reasonable width.
         d.   Buildings shall be sited in an orderly fashion in sympathy with the natural features of the site. Excessively long unbroken building facades shall be avoided.
         e.   The floor plans of residential units shall have proper orientation, access and view to adjacent private and public open space.
         f.   Through traffic shall be discouraged and the intrusion of automobiles into the privacy of residential environments shall be minimized while maintaining the convenience of access between the units and parking areas.
         g.   Adequate building setbacks, open spaces and landscaped buffers shall be provided around the perimeter of the property.
      4.   Neighborhood Facilities: When an appropriate and adequate neighborhood facility, such as a swimming pool, tennis courts or gymnasium/health club, is constructed and made available to the residents of the development an increase of up to ten percent (10%) in the base residential density may be granted.
      5.   Public Facilities: Where an appropriate and adequate public facility or facilities, such as a library, community center, day care facility, park, school, fire station, utilities or storm water management system serving the community as a whole, or a part thereof beyond the subject site, is (are) constructed in a manner acceptable to the suitable operating agency, an increase of up to twenty five percent (25%) in the base residential density may be granted. Where only the land for such a facility is dedicated to the public, an increase of up to fifteen percent (15%) in the base residential density may be granted.
Bonuses may be added together if more than one is present. However, the maximum permitted residential bonus shall be 1.0 times the maximum number of legal, standard lots that can be subdivided on the property pursuant to the underlying zoning district as calculated by multiplying 1.0 times the gross square feet of the property, less rights of way currently utilized for state or county roads and less five percent (5%) of the remaining gross area for local collector roads, divided by the minimum lot size permitted in the zoning district. The density bonuses granted herein are discretionary on the part of the Village. Bonuses less than the maximum for the design features specified above may be granted.
   E.   Modifications:
      1.   Except as noted below, the yard, lot area, lot width, lot shape, lot coverage, height and dwelling size requirements and the limits on combinations of principal structures and uses may be modified under a Residential Planned Unit Development, subject to the standards set forth in subsection G.
      2.   The required yards along the periphery of the Residential Planned Unit Development shall be at least equal in width or depth to those of the directly adjacent zoning district(s), not counting districts removed by the presence of an intervening publicly dedicated street right of way.
      3.   Requirements regarding any improvements covered under the Riverwoods Subdivision Ordinance, including sidewalks, streets, curbs, gutters, sanitary sewers, storm sewers, water lighting, landscaping, parking and retention/detention facilities shall be modified only as specifically provided for in the special use ordinance authorizing the Residential Planned Unit Development.
   F.   Procedures: A Residential Planned Unit Development shall be reviewed as a "special use" in accordance with the procedures and standards of this Section, and shall be processed in three stages as set forth below.

      2.   Modification Standards: In addition to the findings required above, the following standards shall be utilized by the Village in considering applications.
         a.   Integrated Design: A Residential Planned Unit Development shall be laid out and developed as a unit in accordance with an integrated overall design. This design shall provide for safe, efficient, convenient and harmonious grouping of structures, uses and facilities, and for appropriate relation of space inside and outside buildings to intended uses and structural features.
         b.   Beneficial Common Open Space: Any common open space in the development shall be integrated into the overall design. Such spaces shall have a direct functional or visual relationship to the main buildings and not be of isolated or leftover character.
         c.   Functional and Mechanical Features: Exposed storage areas, trash and garbage retainers, exposed machinery installation, service areas, truck loading areas, utility buildings and structures, and similar accessory areas and structures shall be accounted for in the design of the project and made as unobtrusive as possible. They shall be subject to such setbacks, special planting or other screening methods as shall reasonably be required to prevent their being incongruous with the existing or contemplated environment and the surrounding properties.
         d.   Visual and Acoustical Privacy: The development shall provide reasonable visual and acoustical privacy for each dwelling unit. Fences, insulations, walks, barriers and landscaping shall be used as appropriate for the protection and aesthetic enhancement of property and the privacy of its occupants, screening of objectional views or uses and reduction of noises.
         e.   Ownership Plan: The development may consist of conventionally subdivided lots to be sold, unsubdivided single ownership, separate condominium ownership of structures, or other ownership methods, provided that the ownership plan ensures the continued maintenance of the properties and of the various amenities and conservation and design features of the Residential Planned Unit Development as a whole.
         f.   Energy Efficient Design: A Residential Planned Unit Development shall be designed with consideration given to various methods of site design and building location, architectural design of individual structures and landscaping design capable of reducing energy consumption within the development. Design features or facilities which utilize solar or wind energy, or which effectively reduce consumption or use of water, motor vehicles' nonrenewable energy sources or sewage treatment facilities will be encouraged to the extent to which they conform with the other objectives of this Title.
         g.   Landscape Conservation and Visual Enhancement: The landscape in a Residential Planned Unit Development shall be conserved and enhanced, insofar as practical, by minimizing tree and soil removal, and the conservation of special landscape features such as streams, ponds, groves and land forms.
