   M.   Criteria For Rezoning To R-1A: The general purpose and intent of this zoning district is to permit a PUD which is primarily residential on property originally within an R-1 zoning district, if substantial and sufficient justification exists to show that the proposed development is the best alternative to the R-1 district and if that justification arises from conditions or circumstances other than economic ones. (Ord., 11-17-1987)

The plan/zoning board of appeals shall not recommend a rezoning to R-1A for purposes of a PUD unless it shall make findings of fact that the proposed development meets all the following criteria: (Ord., 11-17-1987; amd. Ord. 0-03-35, 9-15-2003)

      1.   Special conditions and circumstances exist as a result of surrounding property or within the land itself and which are not generally applicable to other similarly zoned properties.

      2.   The proposed PUD will not be detrimental to the public health, safety, morals, comfort or general welfare or injurious to other property or improvements in the neighborhood.

      3.   The proposed PUD shall provide adequate utilities, roads, drainage, and/or other facilities and not substantially increase congestion in the public streets, increase the danger of fire, or flooding, nor diminish and impair property valuations in the vicinity of the subject property with due consideration of the existing permitted uses.

      4.   The proposed PUD will not alter the essential character of the locality, nor impede or discourage the development or adjacent land in accord with their current zoning district within which they lie. It is not the intent of the R-1A zoning district to foster different land uses on adjacent properties or create spot zoning.

      5.   The proposed PUD is in harmony with the spirit and intent of this title, and the city's comprehensive plan. (Ord., 11-17-1987)

The plan/zoning board of appeals shall not recommend a rezoning to R-1A unless it makes findings of fact that the reasons set forth in the application justify the granting of the PUD, and that each variation from the normal zoning requirements for that district is the minimum variation that will make possible the reasonable use of the land.

The plan/zoning board of appeals shall further make a finding that the granting of the PUD will be in harmony with the general purpose and intent of this title, and will not be injurious to the neighborhood, or otherwise detrimental of the public welfare. (Ord., 11-17-1987; amd. Ord. 0-03-35, 9-15-2003)

The board may recommend that such conditions and restrictions are imposed upon the location, construction, design and use of property benefited by a granting of the rezoning as may be necessary or appropriate to comply with the foregoing standards and to protect adjacent property and property values. (Ord., 11-17-1987)

The special use permit granted under this title shall be valid for one year. If substantial construction of the developer has not been initiated within one year of the date of the passage of an ordinance granting a special use permit, said permit shall be terminated and the zoning shall revert to R-1. The plan/zoning board of appeals may accept an application to extend the effective special use permit for a period of ninety (90) days, and may recommend to the city council such an extension, and the city council may approve the extension. A maximum of two (2) such extensions may be approved. (Ord., 11-17-1987; amd. Ord. 0-03-35, 9-15-2003)

Violation of such conditions and restrictions, when made a part of the terms under which an R-1A zoning is granted, shall be deemed a violation of this title and punishable under chapter 12, "Violations; Penalties", of this title. (Ord., 11-17-1987)
