(a) General Considerations.
(1) Adequacy of Design. Design standards and requirements outlined in this Section shall be utilized by the Village in determining the adequacy of all plans for proposed planned unit developments.
(2) Consideration of Comprehensive Plans. Consideration shall be given to applicable provisions of the Village Comprehensive Plan, Official Map and other adopted plans as they pertain to future school sites, recreation sites, water supply, sewage treatment systems, highway and street alignments, environmental integrity, and other public facilities where appropriate.
(3) Consideration of Existing Adjacent Development. The development of the proposed PUD shall take into consideration relevant features of adjacent existing development.
(4) Unsafe or Hazardous Conditions. Land with unsafe or hazardous conditions, such as open quarries, unconsolidated fill, floodplains or steep slopes, shall not be developed unless the PUD provides for adequate safeguards which are approved by the Village Board.
(b) Location of Structures. Specific lot size, building location, height, size, floor area, and other such requirements shall be based upon determination by the Village Board, following advisory recommendations from the Plan Commission, as to their appropriateness to the proposed uses and structures as they relate to the total environmental concept of the planned development, consistent with the criteria set forth in this Article, and, as near as practicable, consistent with standards established in applicable existing basic zoning districts and regulations, and with those generally accepted basic standards necessary to insure the protection of the public health, safety and general welfare of that area of the community.
(c) Minimum Area Requirements. Areas designated as planned unit developments shall contain a minimum development area as follows:
Principal Uses Minimum Area of PUD
Residential PUD 3 acres
Commercial PUD 5 acres
Industrial PUD 5 acres
Mixed Compatible Use 5 acres
(d) Allowable Residential Densities
(1) General Lot Area, Density, Width and Setback/Yard Requirements.
a. In a PUD Planned Unit Development Overlay District, area and width requirements of the basic use district may be modified; however, in no case shall the average density in a residential district exceed the number of dwelling units by more than five percent (5%) that would have been permitted if the planned unit development regulations had not been utilized.
b. Setbacks required by the underlying base use district may be modified in PUD Planned Unit Development Overlay Districts; however, no setback shall be less than twenty-five (25) feet from any street right-of-way.
c. No principal structures in planned unit developments shall be located closer than thirty (30) feet to another structure.
d. Structures in residential PUD Planned Unit Development Overlay Districts shall have a rear yard of not less than twenty-five (25) feet.
(2) Minimum Lot Area Requirements. Provided the overall number of dwelling units per acre (density) is not increased by more than five percent (5%) beyond the number of dwelling units that would have been permitted if the PUD District had not been utilized, and provided adequate open space is maintained, the planned unit development may include lot areas per dwelling unit smaller than those normally required in the underlying zoning district. However, no lot shall be less than the minimum lot areas indicated below:
Use | Minimum Lot Area per Dwelling Unit (square feet) |
Single-family | 6,000 |
Two-family | 4,000 |
Multiple-family (1 story) | 3,000 |
Multiple-family (2 story) | 3,000 |
Multiple-family (3 story) | 2,000 |
(3) Residential Permitted Densities Standards; Common Open Space Requirements. In the case of residential uses, the allowable density shall be based on the following considerations:
a. That there will result an appropriate relationship between the number of dwelling units and the facilities required and available to service them, such as sewer, water, schools, streets, and other appropriate municipal services.
b. That there will be an appropriate provision of common open space to compensate for clustering or other concentration of dwelling units, consistent with the goal of creating a desirable living environment. Except as provided below, no plan for a planned unit development shall be approved unless such plan provides for permanent open space equivalent to twenty percent (20%) of the total area in single-family residential planned unit developments, twenty-five percent (25%) in multi-family residential planned unit developments, and five percent (5%) in commercial/industrial planned unit developments. Such open space may be in any of the following forms, provided they contribute realistically and specifically to the enhancement of the environmental character of the development for benefit of the residents thereof and the general community:
1. Natural areas such as woods, unique meadows, marshes, lakes, wetlands, streams and ponds, providing either an environmental amenity or serving a useful ecological purpose.
2. Agricultural areas, including prime crop land, pasture, orchards, and tree nurseries, contributing to the preservation of the agricultural land resource or significantly contributing to the environmental character of the area.
3. Recreational areas, such as parks, parkways, greenbelts, playfields, and golf courses.
c. That there will result an appropriate relationship between the character of existing developments or likely to result from the zoning of property thereto.
(e) Building Height and Area Requirements.
(1) Buildings in a planned unit development shall not exceed the height permitted in the basic use district.
(2) Buildings in a planned unit development shall have a minimum area that is equal to or greater than that required in the basic use district.
(f) Single Parcel, Lot or Tract. At the time of filing, the land proposed for a PUD Planned Unit Development Overlay District shall be considered as one (1) tract, lot or parcel, and the legal description must define said PUD as a single parcel, lot or tract.
