§ 154.099  PUD, PLANNED UNIT DEVELOPMENT OVERLAY DISTRICT.
   (A)   Purpose. This overlay district is established to achieve the coordinated integration of land parcels and large commercial and retail establishments into the community, as well as appropriate mixes of residential, commercial and industrial uses. It is recognized that traditional setbacks, parking, open space requirements, use and subdivision regulations may not always be appropriate to achieve high quality development. Specifically, the PUD Overlay District is intended to encourage:
      (1)   Innovations in residential development to provide for greater variety in tenure, type, design and siting of dwellings, open space and parking; and to promote conservation and more efficient use of land;
      (2)   More convenience in location of accessory commercial and service areas;
      (3)   The preservation and enhancement of desirable site characteristics such as natural topography and geologic features and the prevention of soil erosion;
      (4)   To allow variation from the provisions of this chapter including setbacks, height, lot area, width, depth, yards and the like; and
      (5)   A high standard of site and building design for commercial and retail establishments that integrate well into the community.
   (B)   Authorization. A rezoning to a PUD Overlay District may allow the following:
      (1)   Variety. Within a comprehensive site design concept, a mixture of land uses, housing types and densities;
      (2)   Sensitivity. Through the departure from the strict application of required setbacks, yard areas, lot sizes, minimum house sizes, minimum requirements and other performance standards associated with traditional zoning, a PUD can maximize the development potential of land while remaining sensitive to its unique and valuable natural characteristics;
      (3)   Efficiency. The consolidation of areas for recreation and reductions in street lengths and other utility-related expenses;
      (4)   Flexibility. The project may be granted flexibility from the strict zoning standards of this chapter to promote a desirable and creative environment that might be prevented through the strict application of zoning and subdivision regulations of the city.
      (5)   Density transfer. The project density may be clustered, basing density on a number of units per acre in place of specific lot dimensions; and
      (6)   District integration. The combination of uses that are allowed in separate zoning districts such as:
         (a)   Mixed residential uses to allow both densities and unit types to be varied within the project;
         (b)   Mixed residential uses with increased density based upon the greater sensitivity of PUD projects to regulation; and
         (c)   Mixed land uses with the integration of compatible land uses within the project.
   (C)   Approval standards. The city shall consider a proposed PUD Overlay District against the following standards:
      (1)   The PUD provides a development pattern in harmony with the objectives of the Comprehensive Plan.
      (2)   The PUD is designed in accordance with the design guidelines in §§ 154.115 through 154.128 of this chapter.
      (3)   The PUD prioritizes the conservation of woodlands, wetlands, other natural features, where applicable.
      (4)   The PUD does not conflict with the protection of health, safety and welfare of the community.
      (5)   The location of the buildings, parking areas, and other features is compatible with respect to the topography of the area and existing natural features such as streams, bluffs and woodlands.
   (D)   Approval standards for NRSF and LDSF Districts.
      (1)   This purpose of this section is intended to encourage creative site design for the conservation of land and provision of other public benefits through density incentives and by allowing deviation from the strict provisions of this chapter related to setbacks, heights, lot area, width, depth and yards. Density incentives are provided to owners and developers of all land in the Natural Resource Single-Family Residential and Low Density Single-Family Residential Districts regardless of size. Density incentives are offered in exchange for public benefits that achieve Comprehensive Plan goals for open space, habitat and rural character protection, low impact storm water design, trails, high quality housing and use of public sewer and water service by:
         (a)   Defining in quantified terms the significant public benefits that can be used to earn density incentives;
         (b)   Providing rules and formulas for guiding the calculation of density incentives earned by each benefit;
         (c)   Preserving land for wildlife habitat and unique natural resources and reducing negative impacts on the environment;
         (d)   Designing land efficiently resulting in smaller networks of utilities and streets thereby lowering development costs and public investments;
         (e)   Creating common open space that provides a unified landscape for the use and enjoyment of the neighborhood community and/or the general public; and
         (f)   Providing a review process to allow evaluation of proposed density increases and the public benefits offered to earn them, and to give the public opportunities to review and comment.
      (2)   The density incentive system is described and defined as follows:
         (a)   The density incentive is expressed as additional dwelling or bonus units (BU) earned per specified amount of public benefit provided;
         (b)   Bonus units may be earned through any combination of the listed public benefits or amenities;
         (c)   Through the review process, public benefits and bonus units not identified in this section may be proposed by either the developer or the City; and
         (d)   The awarding of bonus units for each proposed public benefit shall be guided by the following framework. The applicant, Planning Commission, City Council and staff may suggest other award levels for benefits that are in keeping with the overall purpose of this section. The City Council shall award the bonus units based on its evaluation of the entire PUD proposal. Based on this evaluation, the Council may deviate from the following framework at its discretion. In its evaluation of each project, the City will consider the capacity of the land to handle increased densities. The City may determine that the land cannot support the proposed densities due to physical limitations or potential negative impacts which may include, but are not limited to: soils; slope; loss of vegetation; drainage; habitat; sewer capacity; and traffic.

         (c)   The bonus units for each public benefit shall be calculated individually and rounded to the nearest tenth. In summing the bonus units for more than one public benefit, fractional numbers shall be added together and rounded to the nearest whole number; one-half or more dwelling units are rounded up.
         (d)   The total number of dwelling units may not exceed a gross maximum density of two units per buildable acre. Higher maximum densities may be allowed based on demonstrated land development capacity, environmental impact, impact on adjacent properties and transportation system as well as available capacity of City sewer and water service.
      (4)   All properties, regardless of size, in the NRSF and LDSF Districts are subject to this division (D), which creates a PUD Overlay District to encourage density incentives within said districts.
   (E)   Permitted uses.

      (1)   Comparison with approved development schedule. The Planning Commission shall compare the actual development accomplished in the various portions of the PUD with the approved development schedule.
      (2)   Extension of limits of development schedule. Upon recommendation of the Planning Commission and for good cause shown by the developer, the City Council may extend the limits of the development schedule.
      (3)   Construction rates of dwelling and open space. The construction and provision of all of the common open space and public and recreational facilities that are shown on the final development plan must proceed at the same rate as the construction of dwelling units, if any. The Zoning Administrator shall review all of the building permits issued for the PUD and examine the construction that has taken place on the site. If it is found that the rate of construction of dwelling units is greater than the rate at which common open spaces and public and recreational facilities have been constructed and provided, the Zoning Administrator shall forward this information to the City Council for action.
      (4)   Security. A irrevocable letter of credit in form acceptable to the City shall be required to guarantee performance by the developer. The amount of the letter of credit and the specific elements of the development program that it is intended to guarantee will be stipulated in the PUD agreement.
   (U)   Control of PUD following completion.
