All mixed use planned unit developments (PUDs) shall be developed in accordance with the standards of this section, provided however, any residential components of the developments shall also conform to all the requirements of § 153.215(B) above of this chapter except § 153.215(B)(16)(e).
   (A)   Purpose.
      (1)   The purpose of this section is to establish requirements and review procedures for mixed-use projects that may include a full range of housing types and compatible commercial and institutional uses. In order to encourage high-quality design and innovative arrangements of buildings and open space uses throughout the project site, these regulations provide for substantial flexibility from conventional use and dimensional requirements of the zoning districts.
      (2)   In keeping with the purpose of these regulations, planned unit developments, where allowed, are always a conditional use subject to the procedures set forth in §§ 153.235 through 153.244 of this chapter.
   (B)   Project requirements.  The following minimum requirements shall be applicable to mixed use planned unit developments.
      (1)   Minimum project size.  Five acres.
      (2)   Maximum density/intensity.
         (a)   For residential portions of the project the maximum densities shall be those listed in § 153.215(B) of this chapter. The density bonuses in accordance with § 153.215(C) of this chapter shall likewise be applicable.
         (b)   Except as provided in § 153.120(E), SH Overlay District, or § 153.121, WSW Water Supply Watershed District, for nonresidential portions of the project the maximum floor area ratio (FAR) and maximum impervious surface ratio (ISR) shall be:
Use Type
Office use
      (3)   Uses allowed within the project.  All uses listed as either permitted or conditional in the zoning district in which the project is proposed. Residential dwelling unit types are allowed in accordance with § 153.215(B)(3) of this chapter.
      (4)   Residential areas.  Unless otherwise specified in this section, residential portions of planned unit developments shall meet all requirements of § 153.215(B) of this chapter.
      (5)   Nonresidential areas.  Nonresidential portions of planned unit developments shall meet the following requirements.
         (a)   Public water and sewer.  Public water and sewer must be provided to the site.
         (b)   Minimum front yard setback or setback from any dedicated street.  Fifty feet at project boundary.
         (c)   Minimum side yard setback at project boundary.  Thirty feet (except on corner lots where 50 feet shall be provided).
         (d)   Minimum rear yard setback at project boundary.  Thirty feet.
         (e)   Minimum lot width (as measured at required front yard setback).  One hundred feet. In no case shall the front lot width at the street right-of-way line be less than 50 feet.
         (f)   Maximum building height.  Forty feet.
         (g)   Off-street parking and loading.  Off-street parking and loading areas shall conform to all minimum requirements for each use as set forth in §§ 153.185 through 153.188 of this chapter. Off-street parking areas shall be separated from interior streets within the project. No parking space shall be located on, along or otherwise be directly assessed by an interior street. All off-street loading areas (for loading and unloading of goods) shall be located in the rear of buildings except that the areas may be located at building sides when screened from view at the front of the building.
         (h)   Private streets.  Private streets within the development shall be so designed and constructed to carry vehicular traffic from public streets to parking or service areas within the development. All private streets shall, at a minimum, meet the following requirements:
            1.   Minimum pavement widths, back of curb to back of curb.
               a.   Local access street.  Thirty-two feet.
               b.   Collector street.  Forty feet.
            2.   The edge of pavement of any private street shall be no closer than 40 feet to any building except that a street may be located within 20 feet of an accessory building and except that this requirement shall not apply to passenger and goods loading and unloading drives and facilities.
            3.   All streets and parking areas shall be paved and bordered by a standard 24-inch concrete curb and gutter. Storm drainage shall be installed in accordance with the standards required by the city.
         (i)   Screening.  Screening shall be required at the following locations:
            1.   Along major thoroughfares (as shown on the city’s thoroughfare plan), but the screen shall not hinder sight distance where project streets or entrances intersect with thoroughfares;
            2.   Within the project, along the boundaries between areas planned for nonresidential uses, and areas planned for residential uses. The screening shall be located on the nonresidential side of the boundary. Private recreation areas associated with residential uses shall not be required to be screened from residential uses;
            3.   Along a property line or a street bounding the project where the property line or street separates the project from any areas zoned or used for residential purposes;
            4.   The screening shall materially screen the project from the view of the adjoining property, and from the view of residential areas within the project. The screening shall otherwise be in compliance with § 153.046 of this chapter; and
            5.   In cases where screening is required by this chapter and devices such as existing vegetation or topographical features or extreme size of the tract involved would render the installation of screening unnecessary, the City Council is hereby empowered to accept the existing features as meeting the general screening requirements. The decision shall be based on the spirit and intent of this section. The vacancy or non-use of adjacent property shall not negate the necessity for installation of screening. If at any time after the existing features are altered so as to render them inadequate for screening, as described in this section to achieve the required screen, the developer shall be required to make the necessary improvements to achieve the required screen.
         (j)   Paved facilities.  Except for pedestrian walkways and pedestrian courts and paved facilities specifically designed and designated for passenger or goods loading and unloading no paved facilities (streets, drives or parking areas) shall be located closer than 20 feet from the front or rear of any building or ten feet from the side of any building.
         (k)   Off-street parking areas.  Off-street parking areas and all internal streets shall provide safe and convenient access for firefighting and refuse collection vehicles and service and delivery vehicles.
         (l)   Front entrances.  The front entrance to any principal building shall not directly face the designated goods loading area of any other principal building, unless there is a separation of at least 150 feet between the building and sufficient landscaping to materially screen the loading area from view from the front of the opposing building.
         (m)   Location of principal buildings.  No principal building shall be located closer than 70 feet to any other principal building within the development.
         (n)   Phases.  Each phase of a multi-phased project shall be able to stand as an independent project. As used in this section, the term PHASE shall refer to that portion of the project for which the applicant is seeking a conditional use permit.
