The city council may authorize, by ordinance, after a public hearing and a report by the zoning board of appeals held and made in the manner provided for amendments in this title, the location and development in the R-1 and R-2 residential districts of a planned residential development of single- family dwellings on not less than fifteen (15) acres of land; and provided, that every development under this chapter shall be consistent with the purpose and intent of this title, and shall be laid out and developed as a unit in accordance with an integrated overall design, as approved and authorized by the city council. (Ord., 5-13-1968)

The buildings shall be used only for single-family dwellings and permitted accessory uses, such as garages, storage space, and project activities. (Ord., 5-13-1968)

The specific requirements of this title for intensity of land use for the designated residential use district in which the development is located shall be maintained. (Ord., 5-13-1968)

   A.   All other sections of this title may, by specific mention, be varied in whole or in part for any planned residential development under the terms of this chapter.

   B.   However, in no case shall the allowable lot area, width or yard requirements in the residential use district be reduced to less than the corresponding requirements in the next less restricted residential use district, but in no case less than ten thousand (10,000) square feet.

   C.   Where a reduction of lot area is allowed within the limits above, an area equal in aggregate area to not less than the sum of such area reduction in all lots shall be either set aside as common land to be used by owners of homes in the development, or may be added to the public lands, provided dedication is accepted by the city. (Ord., 5-13-1968)

In determining the total number of lots which may be created under the terms of this chapter in accordance with the intensity of use provided by the designated use district, the land available for development (which shall not include any easement for utilities or access, or provision for floodwaters) shall be reduced by twenty percent (20%), and the remainder shall be divided by the minimum lot area of the designated use district in which the development is located. The resulting figure, reduced to the closest smaller whole number, shall be the greatest number of lots developable under the terms of this chapter. (Ord., 5-13-1968)

   A.   Each proposed lot must have at least fifteen percent (15%) of its periphery bounded by the common open area or dedicated lands. Lots may face each other across streets, but may not back up to each other. The average minimum width of any continuous open space shall be not less than fifty feet (50'). All open spaces shall be directly accessible to a public street or a public area having access to a public street. (Ord., 5-13-1968)

   B.   In addition, the arrangement and use of the common land or land to be dedicated to the city and the method of maintenance of any common land shall be subject to approval by the city council before the provisions of this section apply. (Ord., 5-13-1968; amd. 2015 Code)
