PD-H districts may hereafter be established in accordance with the general procedures and requirements set forth in article 30. Intensity (or density) of residential use in any PD-H district hereafter created shall be established at the time of amendment creating the district.

31.2.1. Principal uses and structures permitted generally. The following principal uses and structures shall be permitted generally:

(1)

Dwellings, detached, semi-detached and attached, including multifamily; residence hotels, apartment hotels, and other facilities including lodgings other than for transients, except as permitted as accessory uses;

(2)

Public schools through the secondary level, and private schools with similar academic curriculums, except that no school shall conduct training in the industrial arts in such a manner that there is external evidence of the conduct of such activity;

(3)

Day nurseries, kindergartens, day care centers for children or for the elderly;

(4)

Noncommercial social, recreational and cultural facilities, such as neighborhood or community centers, game rooms, libraries, golf courses, swimming pools, and the like;

(5)

Places of worship; and

(6)

Structures and uses required for operation of a public utility, performance of a governmental function, or performance of any function found reasonably necessary for the operation and maintenance of the planned development and otherwise permitted under these or general regulations, subject to the requirements thereof.

31.2.2. Accessory uses and structures permitted generally. Customary accessory uses and structures clearly incidental to permitted principal uses and structures shall be permitted in this district, subject to the limitations of section 73.1, with home occupations limited to 25 percent of residential floor area. In addition, agricultural uses accessory to principal uses in the district may be permitted other than on the lots or adjacent to the building sites of such principal uses, where it is found that satisfactory arrangements have been made for continuing management and maintenance. In connection with such agricultural uses, there shall be no sales on the premises and no commercial animal or poultry operations or kennels.

31.2.3. Additional principal or accessory structures and uses. Where the scale, character and/or location of particular planned developments justify additional principal or accessory structures and uses, they may be specifically authorized by city council at the time of rezoning to PD-H status, or subsequent to rezoning by the board of adjustment as special exceptions.

Examples of such additional principal or accessory uses and structures include convalescent or rest homes in large planned developments primarily for the elderly, convenience or other commercial facilities in large planned developments, or in developments where such facilities are not conveniently available in the vicinity, personal service establishments, or medical or dental offices. The following requirements and limitations shall apply:

(1)

No evidence of any such additional facilities shall be apparent from outside the planned development;

(2)

Such uses and structures shall be designed and intended primarily to serve occupants of the development and their guests, and not to attract other visitors or customers;

(3)

Scale of such facilities shall be in keeping with scale of residential development to the period at which such facilities are installed or provided, except that in the case of staged development, facilities may be scaled to serve residential occupancy anticipated within one year;

(4)

Commercial, service or office floor area authorized for such additional principal or accessory structures and uses shall not exceed ten percent of an amount equal to residential floor area developed, or staged for completion within one year;

(5)

Such facilities shall be so located, and access and parking so designed, as to maximize convenience for occupants of the development, and minimize hazards or annoyances;

(6)

Off-street parking required for such nonresidential uses shall, where reasonably feasible, be combined with other nonresidential parking at neighborhood or community centers, and when so combined shall not be required to exceed one-half the amount required generally at section 70.1;

(7)

No such facilities shall be permitted if their construction would reduce open space, or increase coverage by buildings or impermeable surface, or increase residential floor area beyond limits established for the district; and

(8)

No outside storage shall be permitted with any accessory use.

The following requirements and limitations apply to dwelling and lodging uses within PD-H districts hereafter created from or within other districts. Application of these requirements and limitations, and definitions and rules of interpretation of the terms involved, appear at section 73.16.

_____

PD-H District Created From or Within District

Gross land area × FAR = Maximum permitted residential floor area.

Gross land area × OSR = Minimum required open space.

Gross land area × LSR = Minimum livability (nonvehicular open space, a part of total open space).

Gross land area × RSR = Minimum recreation space, a part of livability space.

_____

Site planning within the district shall provide protection of the development from potentially adverse surrounding influences, and protection of surrounding areas from potentially adverse influences within the development including prevention of excessive storm drainage in runoff peaks. In particular:

31.4.1. Principal vehicular access points. Principal vehicular 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 and/or traffic dividers shall be required where existing or anticipated heavy flows indicate need. Minor streets shall not be directly connected with streets outside the district in such a way as to encourage use of such minor streets by substantial amounts of through traffic.

31.4.2. Access for pedestrians and bicycles. Access for pedestrians and cyclists entering or leaving the district shall be by safe and convenient routes. Such access need not be adjacent to, or limited to the vicinity of, access points for automotive vehicles. Where there are crossings of pedestrian ways and vehicular routes at edges of planned developments, such crossings shall be safely located, marked, and controlled; and where such ways are exposed to substantial automotive traffic at edges of districts, safeguards including fencing may be required to prevent crossings except at designated points. Bicycle and/or bridle paths, if provided, shall be so related to the pedestrian system that street crossings are combined.

31.4.3. Protection of visibility; automotive traffic, cyclists, and pedestrians. Protection of visibility for automotive traffic, cyclists, and pedestrians shall be as generally provided at section 73.10, corner visibility. In addition, where there is pedestrian, bicycle, or equestrian access from within the development to a street at its edges by paths across yards or other open space without a barrier to access to the street, no material impediment to visibility, as defined therein, shall be created or maintained within areas appropriate to the circumstances of the case, but in any event within a visibility triangle equivalent to that required in section 73.10.

31.4.4. Uses adjacent to single-family residence districts. If a PD-H district adjoins a single-family residence district, then either:

(1)

The portion of the perimeter of the PD-H district so adjoining shall be planned and developed only for uses permitted in the adjoining residential district and in accordance with all other requirements for such district; or

(2)

Common open space for the PD-H district to a depth of 100 feet from the district boundary shall be provided. No intensive recreational use or off-street parking shall be permitted within 75 feet of the district boundary in such cases.

31.4.5. Yards, fences, walls, or vegetative screening at edges of PD-H districts. Yards, fences, walls, or vegetative screening shall be provided at edges of PD-H districts where needed to protect residents from undesirable views, lighting, noise, or other off-site influences, or to protect residential occupants of other districts from similar adverse influences within the PD-H district. In particular, extensive off-street parking areas, service areas for loading and unloading vehicles other than passenger, and areas for storage and collection of refuse and garbage shall be screened.

31.4.6. Height limitations at edges of PD-H districts. Except along boundaries where adjoining districts permit greater heights within similar areas, no portion of any building in such district shall project through imaginary planes leaning inward from district boundaries at an angle representing an increase in height for each foot of horizontal distance perpendicular to the boundary as follows: Adjacent to Residence 1, 1-A, 1-B, 1-C, 2 and 2-C districts, 0.5 foot; adjacent to other districts, 1.0 foot.

31.4.7. Signs permitted. Signs shall be permitted in accordance with the provisions of article 72—Sign control regulations.

(Ord. No. 07-460, § 2, 6-28-2007; Ord. No. 21-46, § 1(Exh. A. § B.2.), 2-25-2021)

The site plan shall provide for safe, efficient, convenient and harmonious groupings of structures, uses, and facilities, for appropriate relation of space inside and outside buildings to intended uses and structural features, and for preservation of desirable natural or historic features and minimum disturbance of natural topography. In particular:

31.5.1. Streets, drives, parking and service areas. Streets, drives, parking and service areas shall provide safe and convenient access to dwelling units and general facilities, and for service and emergency vehicles. Streets shall not be so laid out as to encourage outside traffic to traverse the development on local streets, nor occupy more land than is required to provide access as indicated, nor create unnecessary fragmentation of the development into small blocks. In general, block size shall be the maximum consistent with use and shape of the site and the convenience and safety of occupants.

31.5.2. Vehicular access to streets. Vehicular access to streets shall be limited and controlled as follows:

(1)

Streets or portions of streets serving 50 or fewer dwelling units. If the street or portion thereof serves 50 or fewer dwelling or lodging units, vehicular access from off-street parking and service areas may be directly to the street from the sites of individual dwelling or lodging units. Determination of number of units served shall be based on normal routes of traffic anticipated in the development.

(2)

Vehicular access to other streets or portions of streets. Vehicular access to other streets or portions of streets from off-street parking and service areas shall be so combined, limited, located, designed, and controlled as to channel traffic from and to such areas conveniently, safely, and in a manner that minimizes marginal traffic friction and promotes free flow of traffic on streets without excessive interruption.

31.5.3. Ways for pedestrians and cyclists; use by emergency or service vehicles. Walkways shall form a logical, safe and convenient system for pedestrian access to all dwelling units, appropriate project facilities, and principal off-site pedestrian destinations. Maximum walking distance in the open between dwelling units and parking areas, delivery areas, and refuse and garbage storage areas shall not exceed 150 feet.

Walkways to be used by substantial numbers of children as play areas or as routes to school or other destinations shall be so located and safeguarded as to minimize contact with normal automotive traffic. If substantial bicycle traffic is anticipated, bicycle paths shall be coordinated with the walkway system. Street crossings shall be held to a minimum on walkways, bicycle paths, and/or bridle trails and shall be located and designed to promote safety and appropriately marked and otherwise safeguarded.

Pedestrian ways and bicycle paths, appropriately located, designed, and constructed, may be combined with other easements and used by emergency and service vehicles, but shall not be used by other automotive traffic, including motorbikes and motorcycles.

31.5.4. Protection of visibility; automotive traffic, cyclists, and pedestrians. Protection of visibility for automotive traffic, cyclists, and pedestrians shall be as provided at section 31.4.3.

Definitions, rules for interpretation, and requirements and limitations concerning open space and spacing of buildings or portions of buildings containing dwelling or lodging units shall be as provided at section 73.16.
