Overlay district regulations—Planned district residential (PDR) and planned district residential-limited (PDR-L)
Planned district residential (PDR) and planned district residential-limited (PDR-L) overlay districts are established in accordance with subsection 302.3 of this ordinance and may be enacted from time to time by amendments to this ordinance consisting of appropriate changes in the boundaries of districts in such a manner as best to fit the general pattern of land use established by the comprehensive plan and this ordinance and to further the purposes set forth in section 100. The specific regulations set forth herein apply to the following districts: A-7, A-10, A-15, A-40, office and general business districts.
308.1. Administrative procedure. See subsection 305.
308.2. Design standards. Multiple-family dwellings shall be permitted only in planned district residential (PDR) and planned district residential-limited (PDR-L) overlay districts and shall be subject to the following minimum requirements:
(A) Building design. Applicants are encouraged to design buildings with varied setbacks and/or varied siting to prevent parallel rows of identical buildings. Principal front or rear walls of a building shall be at least 40 feet from any wall of another building. Any side wall of a building may not be less than 30 feet from any side wall of another building.
(B) Compatibility. The basic design, including proposed style and materials, of the proposed buildings, the relationship between the proposed buildings and the site, and the overall physical appearance of the developments shall be in general harmony with the character of the surrounding residential neighborhood and shall not serve to blight or detract from abutting residences or other property.
(C) Relation to utilities and public facilities. Public sewers, shall be required for all developments of ten dwelling units or more and shall be installed by the applicant. Water lines, storm and surface drainage systems and other utility systems must exist or shall be installed by the applicant.
(D) Relation to transportation. Developments of five units or more shall be located along or provide direct access to major streets and highways.
(E) Off-street parking and landscaping. A minimum of two parking spaces per dwelling unit shall be provided for developments of four units or less and a minimum of two and one-half parking spaces per dwelling unit shall be required for developments of five or more. Off-street parking shall be appropriately landscaped within each parking area as required in section 700. No outdoor parking space is permitted within any required front or corner side yard. No outdoor parking space or driveway is permitted within ten feet of any property line. A ten-foot-wide border of grass, vegetation, or other live ground cover is required around the entire perimeter of the site, except for any curb cuts. For standards, see section 505.
(F) Vehicular and pedestrian access points. All developments shall provide the required minimum frontage along an improved and accepted city street. Principal vehicular access for developments of five or more dwelling units shall be from major streets, and access points shall be designed to encourage smooth traffic flow with controlled turning movements and minimum hazards to vehicular or pedestrian traffic. Merging and turnout lanes as well as traffic dividers shall be provided where existing or anticipated heavy flows indicate need as determined by the planning [sic] director of city plan. In no event shall streets within a planned development connect to streets outside the development in such a way as to encourage use of minor streets for through traffic.
Access for pedestrians and bicyclists entering or leaving the PDR overlay district shall be so arranged as to provide safe and convenient routes. Such ways need not be adjacent to or limited to the vicinity of vehicular access points. Pedestrian crossings at edges of the development shall be safely located, marked and controlled. Where there is substantial exposure of pedestrian to vehicular traffic at the edges of the district, fences or other barriers shall be erected and maintained to prevent pedestrian crossings except at designated points. Bicycle and/or bridle paths, if provided, shall be coordinated with the pedestrian way system so that bicycle, horse and pedestrian street crossings are combined.
(G) Yards. The location of buildings and structures in the PDR overlay district shall be regulated by subsection 308.3, Development standards. Lots located in more than one zoning district shall be regulated by subsection 303.1.
(H) Screening. Fences, walls, and/or vegetative screening shall be provided along edges of PDR overlay districts, to protect residents or visitors to such developments from undesirable views, glare, noise or other off-site influences or to protect residents or visitors in adjoining residential districts from similar adverse influences within the PDR overlay district. In both cases, screening shall be designed to control existing or potential adverse views from existing or potential first-floor residential windows in the PDR overlay district or other residential districts. In particular, the following shall be screened:
(1) Off-street parking areas containing more than ten parking spaces. When nearest portions of noncontiguous parking areas are separated by less than 50 feet of landscaped space, as measured from their nearest points, they shall be considered as combined for computing the number of spaces.
(2) Service areas for storage and collection of trash and garbage.
(3) Utility areas such as sewage pumping stations, electric utility substations and the like.
308.3. Development standards. The number of units per acre, dimensions, and other requirements, shall vary according to the district in which it is located. The following tables establish the minimum requirements or maximum allowances for each district:

Up to a 15 percent increase in dwelling units over the maximum density allowance set forth in subsection 308.3 may be permitted if the city council shall have determined compliance with one or more of the following listed in [subsections] (A) through (C) below. Up to a 30 percent increase is permitted if the city council shall have determined compliance with [subsection] (D) below. Any combination of [subsections] (A) through (C) with [subsection] (D) cannot exceed said 30 percent increase. In determining the appropriate percent increase, the city council shall review the recommendation of the director of city plan as to the extent of compliance with any or any combination of [subsections] (A) through (D).
(A) Provision of elderly housing for at least 80 percent of the dwelling units. (With parking requirement of one parking space per dwelling unit.)
