Plymouth City Zoning Code

ARTICLE XXIV

PLANNED UNIT DEVELOPMENT

Sec. 78-310.- Purpose.

The planned unit development (PUD) is provided as a design and planning option, intended to permit flexibility in the regulation of land development; to encourage innovation in land use, form of ownership (such as site condominiums) and variety in design, layout, and type of structures constructed; to preserve significant natural, historical, and architectural features and open space; to promote efficient provision of public services and utilities; to minimize adverse traffic impacts; to provide adequate housing and employment; to encourage development of convenient recreational facilities; and to encourage the use and improvement of existing sites or existing buildings when the uniform regulations contained in other zoning districts alone do not provide adequate protection and safeguards for the site or its surrounding areas or flexibility to consider adaptive re-use of existing structures.

Sec. 78-315. - Conditions.

(a)

Reasonable conditions may be required by the planning commission before the approval of a planned unit development, to the extent authorized by law, for the purpose of ensuring that public services and facilities affected by a proposed land use or activity will be capable of accommodating increased service and facility loads caused by the land use or activity, protecting the natural environment and conserving natural resources and energy, ensuring compatibility with adjacent uses of land, and promoting the use of land in a socially and economically desirable manner. Permit conditions may be drafted in writing specifying conditions of approval and use. Conditions may stipulate that the PUD may only be used for selective land uses provided the restraints advance, rather than injure, the interests of adjacent landowners; are a means of harmonizing private interests in land thus benefiting the public interest; are for the purposes of ensuring that the PUD fulfills the purposes and intent of this section and thus benefit the public interest; and/or possess a reasonable relationship to the promotion of the public health, safety, and welfare. A change of land use (as defined in section 78-21) during operation of the PUD will render the PUD null and void or will require application for a revised PUD.

(b)

Conditions imposed shall be designed to protect natural resources and the public health, safety, and welfare of individuals in the project and those immediately adjacent, and the community as a whole; reasonably related to the purposes affected by the planned unit development; and, necessary to meet the intent and purpose of this article, and be related to the objective of ensuring compliance with the standards of this article. All conditions imposed shall be made a part of the written record of the approved planned unit development which shall include a site plan and written PUD permit conditions signed by the city and the applicant.

(c)

If the conditions set forth herein are not complied with, then the building official shall have the right to compel a show cause hearing by the planning commission or issue a violation pursuant to article XXIV of this chapter. At the show cause hearing, additional conditions may be imposed by the planning commission or the city may require submittal of a new PUD application.

(1)

An applicant or property owner who has been granted final PUD site plan approval shall notify the building official of any proposed amendment to such approved site plan or PUD conditions.

(2)

Minor changes may be approved by the city building official upon certification in writing to the planning commission that the proposed revision does not alter the basic design nor any conditions of the plan imposed upon the original approval by the planning commission. In considering such a determination, the building official shall consider the following to be a minor change:

a.

For residential buildings, the size of structures may be reduced, or increased by five percent provided that the overall density of units does not increase;

b.

Square footage of nonresidential buildings may be decreased, or increased by up to five percent or 10,000 square feet, whichever is smaller;

Changes required or requested by the city for safety reasons shall be considered a minor change.

(3)

Should the building official determine that the requested modification to the approved final PUD site plan is not minor or if a change in land use has occurred which is different than land uses previously approved, re-submittal to the planning commission shall be necessary and new public hearing and notification under section 78-377 shall be required.

(4)

Should the planning commission determine that the modifications to the final PUD site plan significantly alter the intent of the preliminary PUD site plan, a new submittal illustrating the modification shall be required.

(5)

Any deviation from the approved PUD site plan, except as authorized in this section, shall be considered a violation of this article and treated as a misdemeanor, and subject to article XXIV of this chapter. Further, any such deviation shall invalidate the PUD designation.
