§ 1.2. Nature of PD districts and minimum standards.

Each PD District is intended to be a freestanding zoning district in which land uses and intensities of land use may be tailored to fit the physical features of the site and to achieve compatibility with existing and planned adjacent uses. In order to ensure that a PD District implements the policies of the comprehensive plan, and to further ensure that the PD District is in accordance with a comprehensive plan of zoning regulation, it is necessary to establish minimum standards for residential and nonresidential uses proposed for the PD District that must be incorporated within an ordinance adopted by the council (the "PD ordinance").

A.

Land use.

1.

Uses. Unless otherwise provided by the PD ordinance, only those uses authorized by this Unified Development Code are permitted in PD Districts.

(Ord. No. 10-14, § 56, 7-6-2010)

2.

Location. The location of all authorized uses shall be consistent with the PD concept plan and PD site plan.

B.

Open space standards.

Public and private open space. Unless otherwise provided by the PD ordinance, a minimum of 20 percent of the gross land area within the entire PD District shall be devoted to open space, except where a floodplain exists in the proposed development in which case the dedicated floodplain shall be allowed to count for up to 50 percent of the 20 percent open space requirement, and shall be consistent with the open space requirements of the city's parks and open space plan. Open space for PD Districts may be satisfied by either public or by a combination of public and private open space. Open space requirements specified in this subsection are in addition to requirements for site landscaping and buffering. Public open space shall be dedicated to the city.

(Ord. No. 07-18, 6-04-2007)

1.

Preservation of natural features. Unless otherwise provided by the PD ordinance or PD concept plan:

a)

Floodplain areas shall be preserved and maintained as open space; and

b)

Significant stands of native trees and shrubs shall be preserved and protected from destruction or alteration.

2.

Open space allocation. Open space requirements shall be satisfied for each phase of a multi-phased residential development. If open space is not to be provided proportionally among phases of development, the applicant must execute a reservation of open space in a form that will assure the city that such open space will be provided. The city may require that all open space within the district must be provided prior to completion of development within the district.

In a residential planned development, all lots less than 12,000 square feet shall be located within 800 feet of a neighborhood-oriented park or open space corridor, which shall be landscaped and serve as a visual amenity and/or gathering place for socializing with neighbors.

(Ord. No. 07-18, 6-04-2007)

C.

Other minimum development standards.

1.

Dimensional and area standards. Unless otherwise provided by the PD ordinance, dimensional and area standards for uses shall be the most restrictive standards authorized by this Unified Development Code for the same or similar uses.

(Ord. No. 10-14, § 57, 7-6-2010)

2.

Density standards for residential use. Unless otherwise provided by the PD ordinance, a residential planned development shall allow for a density greater than one unit per gross acre and up to two units per gross acre with a mixture of uses and residential unit size with no minimum lot size. The planned development zoning may be allowed based on the following:

•

Topographic conditions that will result in quality open space and building arrangements.

•

Mix of unit types to accommodate elements of "life-cycle" housing.

•

Amount and distribution of open space to enhance value-creation.

•

The overall master plan and arrangement of buildings and uses.

•

The property should be 50 acres or more in size to adequately accommodate the transition to surrounding development.

Additionally, in a residential planned development, a density up to 2.5 units per gross acre may be allowed with the dedication and/or development of additional amenities that would exceed the minimum standards for residential planned developments which could include:

•

Parks and open space.

•

Golf course.

•

Neighborhood amenity/recreation center.

•

Integration of schools into the community fabric.

•

Development of trails and parks in floodplains.

•

Development of municipal parks and recreation facilities.

3.

Anti-monotony standards for residential use.

a)

Exterior wall materials must comply with section 3.1, General Residential District Standards, of article V of this [Unified Development] Code. Additionally, masonry chimneys shall be required on all homes.

b)

Front elevations shall not repeat along any block face without at least four intervening homes of differing appearance on the same side of the street and two intervening homes of differing appearance on the opposite side of the street. The rear elevation of homes backing to open spaces or thoroughfares shall not repeat without at least two intervening homes of differing appearance. Identical brick blends may not occur on adjacent (side by side) properties. Homes may differ in appearance in any two of the following ways:

•

Number of stories.

•

Garage location.

•

Roof type and layout.

•

Articulation of the front facade.

4.

Fencing standards.

a)

Solid fencing shall be cedar standard fencing material (minimum one-half-inch thickness or more). Spruce fencing will not be allowed. All cedar pickets shall be placed on the "public side" facing a street or an alley. All posts and framing shall be placed on the "private side" of the fence. Other types of solid fencing (such as vinyl) may be considered on a case-by-case basis during the review of the PD development plan.

b)

Tubular steel or wrought-iron type fencing shall also be allowed.

c)

Tubular steel or wrought-iron type fencing shall be required on all lots located adjacent to perimeter roadways, open spaces, greenbelts and parks.

d)

Split rail fencing shall be allowed on lots containing 20,000 square feet or more.

e)

Fencing on corner lots constructed adjacent to the street shall provide masonry columns at 45 feet off-center spacing that begins at the rear property lien corner and terminates at least 15 feet behind the front yard building setback line. A maximum six-foot-high, solid board-on-board "panel" cedar fencing or wrought iron-type fencing shall be allowed between the masonry columns along the side and/or rear yard adjacent to a street.

•

On corner lots which have rear lot liens adjacent to alleys or other rear lot lines, fences may be constructed along the side yard adjacent to the street, subject to a minimum five feet setback from the right-of-way. The property owner shall maintain that portion of the property outside of the fence.

•

On corner lots which have rear lot lines adjacent to a side lot line of an adjoining lot(s), only tubular steel or wrought iron-type fences not exceeding 42 inches in height may be constructed beyond the building line. Fences constructed on or behind the building line shall comply with the materials requirement in section 4.e above.

f)

All common areas and perimeter fencing shall be maintained by a homeowners association as specified in the city's subdivision regulations. Perimeter fencing shall be constructed of six-foot-tall tubular steel or wrought iron type fencing with masonry columns and entry features. The planning and zoning commission may consider alternative perimeter screening such as earthen berms with landscaping during the review of the PD development plan.
