      (6)   Overlay Districts:
         (a)   Planned Unit Development.
   (C)   Zoning districts designation of annexed property. All territory which may hereafter be annexed to the town shall be zoned consistent with the land use policy of the comprehensive plan and with the zoning district most similar to the zoning which was applicable prior to annexation, as long as that zoning is consistent with the comprehensive plan land use policy map.

(Ord. 2022-14, passed 9-7-2022)

§ 152.27.A PLANNED UNIT DEVELOPMENT (PUD) DISTRICT.

   (A)   Intent. The intent of the PUD District is to provide a relief mechanism from the prescriptive standards of a regular zoning district. The PUD District is intended to be used to achieve a higher quality of project design than could be accomplished through the strict application of a regular district or set of zoning districts, without adversely impacting the adequate facilities required to serve the property and surrounding area. A PUD District is established through Council approval with a specific PUD District ordinance establishing the development standards and use standards for each PUD District.
   (B)   Applicability. The provisions of this section shall only apply to new development proposals.
   (C)   Limitations on flexibility of planned unit developments. It is not intended that the town automatically grants the initial plan of development proposed by a petitioner. The Town Plan Commission shall approve only such plans of development that are consistent with the public benefits resulting from the planned unit development. Therefore, the Town Plan Commission may require, as a condition of approval and subsequent amendment of the zoning map, any reasonable condition, limitation or design factor that will promote proper development of a Planned Unit Development.
   (D)   Purpose of Planned Unit Development (PUD) ordinance.
      (1)   To designate a parcel of real property as a Planned Unit Development (PUD) including the underlying zoning district;
      (2)   To specify uses or a range of uses permitted in the PUD District;
      (3)   To specify development requirements in the PUD District;
      (4)   To specify the documentation including an overall plan and supporting documentation;
      (5)   To specify any limitation applicable to the Planned Development; and
      (6)   To specify any variations from the underlying zoning district requirements.
   (E)   Prerequisite base zoning. The prerequisite base zoning shall be as indicated in the PUD District ordinance. If a parent tract has multiple zoning districts, each of those zoning districts must be on the prerequisite listing.
   (F)   Minimum project size. The minimum project size for a PUD District shall be a) five acres or more in Residential Zoning District, b) three acres or more in Business and Industrial Zoning Districts, and c) ten acres in Mixed Use District.
   (G)   PUD Principles. A PUD District shall comply with the provision of this chapter. In addition, a proposed PUD District should include concepts and development and design standards that generally offer the following advantages over a standard zoning district:
      (1)   Address the policies included in the comprehensive plan to encourage consistency with the community’s vision as presented in the comprehensive plan.
      (2)   Use design to provide compatibility between areas of different land uses and development intensities within the PUD District.
      (3)   Buffer different types of land uses and development intensities outside of the PUD District from those within the PUD District to increase compatibility or minimize any adverse impact which new development may have on existing or zoned development.
      (4)   Enhance the appearance of neighborhoods by conserving areas of natural beauty, and natural green spaces and provide enhanced amenities and open space.
      (5)   Promote and protect the environmental integrity of the site and its surroundings and provide suitable design responses to the specific environmental constraints of the site and surrounding area.
      (6)   Promote architecture that complements the surroundings.
      (7)   Counteract urban monotony and congestion on streets.
   (H)   PUD development standards. A proposed planned development plan shall be designed to produce an environment of stable and desirable character in keeping with the principles of good neighborhood design, and must provide standards of community amenities, efficiency in street patterns, and areas for parking adequate for the occupancy proposed, or equal to the requirements of this chapter. It must also provide for a development density and related bulk and coverage characteristics in keeping with the requirements of the comprehensive plan and reflecting that of the base zone that contains the land subject to rezoning as a particular Planned Unit Development.
      (1)   Establishment of site development intensity.
         (a)   Before approval of a preliminary planned development plan, a detailed determination of land use intensity shall be declared.
         (b)   Except as otherwise provided below, the development standards for lots in a PUD may be varied from one another and from that allowed by the underlying base zone. The maximum base zone density permitted under the PUD process is as follows:
            1.   Residential use, low density: 0.5 unit/acre or less.
            2.   Residential use, medium density: 0.51 - 3 units/acre.
            3.   Residential use, high density: 3.1 or more units/acre.
         (c)   In calculating the density (net), certain areas inappropriate for development including but not limited to bodies of water, floodplains, wetlands, and rights-of-way, shall be discounted from gross acreage.
         (d)   The Commission shall make a finding that said intensity is consistent with the land use element of the comprehensive plan of current adoption and in the best interest of the city and surrounding areas.
         (e)   If such zoning is not related to the character of development sought by the Planned Unit Development, then the Plan Commission shall determine whether to require a rezoning of the site to a more appropriate zone or to establish a development intensity pursuant to the PUD waiver procedure.
      (2)   Establishment of landscape buffer yard. A minimum 25-foot landscape buffer yard shall be provided within the Planned Unit Development District as a buffer between residential and non-residential uses. This landscape buffer yard shall be maintained as common area, labeled on the development plan/subdivision plat/parcel as common area/landscaping easement. The Declaration of Covenants or other recordable instrument shall state that the landscape buffer yard is common area and maintained by the association or developer of said project. Exception to the minimum buffer yard size requirements include those subdivisions or parcels abutting expressways or arterials and those subdivisions having rear yards abutting a collector, arterial, or expressway then those specific requirements apply. A variety of trees, shrubs and/or ornamental grasses is required. The applicant shall follow the landscaping design and installation standards in § 152.64.
      (3)   Establishment of maximum height, building size. Maximum heights and maximum/minimum building sizes shall be as required in the base zone unless modified by the Plan Commission and approved by the Town Council as part of the preliminary plan approval, unless otherwise specified in this chapter.
      (4)   Open space requirement.
         (a)   Open space shall include cropland, forested areas, pastureland, turf areas, decorative plantings, walkways, active and passive recreation areas, playgrounds, and wooded areas. Open space does not include areas devoted to public or private streets or rights-of-way.
         (b)   No plan for a Planned Unit Development shall be approved, unless such plan provides for permanent open space areas equivalent to the following types of Planned Unit Developments:
            1.   Residential PUD: 20% of gross acreage.
            2.   Mixed-Use PUD: 20% of gross acreage.
            3.   Industrial or Commercial PUD: 15% of gross acreage.
      (5)   Establishment of other site development regulations.
         (a)   PUD shall follow site design and improvement standards in §§ 152.70 through 152.89.
         (b)   Other site development regulations, including but not limited to parking, signs, accessory uses, landscape requirements, environmental standards, flood plain protection, and public and private infrastructure shall be as required in this chapter.
         (c)   The Plan Commission may recommend, and the Town Council may authorize, exceptions to other applicable regulations of this chapter controlling development within the boundaries of a PUD, provided that the Plan Commission shall find that such exception shall be solely for the purpose of promoting an integrated site plan no less beneficial to the tenants or occupants of such development, as well as the neighboring property, than would be obtained under the regulations of this chapter for buildings developed on separate zoning lots.
