§ 5-6 Planned Development District.

5-6.01

Purpose.

The PD District is a zoning district that accommodates multiple uses developed as integrated land use units either by a single owner or a combination of owners.

The PD District allows for the creative master planning of developments larger than five (5) acres. A PD District may be used to permit new or innovative concepts in land use not permitted by other zoning districts, to ensure the compatibility of land uses, and to allow for the adjustment of changing demands to meet the current needs of the community by meeting one or more of the following purposes:

To provide for a superior design of lots or buildings;

To provide for increased recreation and open space opportunities for public use and enjoyment;

To provide amenities or features that would be of special benefit to the property users or to the overall community;

To protect or preserve natural amenities and environmental assets such as trees, creeks, ponds, floodplains, slopes, viewscapes, or wildlife habitats;

To protect or preserve existing historical buildings, structures, features or places;

To provide an appropriate balance between the intensity of development and the ability to provide adequate supporting public facilities and services;

To forward the goals of the Comprehensive Plan; and

To meet or exceed the standards of this Ordinance.

The zoning of a PD District shall be that shown on the development and site plan approved and made a part of the adoptive ordinance and any written special conditions within or attached to the adoptive ordinance or development plan. The ordinance granting a PD District shall include a statement as to the purpose and intent of the PD District granted therein, as well as a general statement citing the reason for the PD request.

5-6.02

Permitted Uses.

A PD District may be approved with any combination of uses allowed by this Zoning Ordinance. The uses permitted in any specific PD shall be enumerated in the ordinance establishing such district, along with any conditions or limitations deemed appropriate for the specified uses,

5-6.03

Prohibited Uses.

Any building erected on land used for any other uses than those shown on the PD development plan, as approved by the City Council.

Any use of property that does not meet the required minimum lot size; front, side and rear yard dimensions and/or lot width; or exceeds the maximum height, building coverage or density per gross acreage as shown in the development's recorded development plan, as approved by the City Council.

Any use deemed by the City Council as being detrimental to the health, safety or general welfare of the citizens of the City.

5-6.04

Design considerations.

A Planned Center District project shall be designed to achieve the following objectives:

The design shall provide for internal compatibility between residential and nonresidential uses such that glare, noise, odors, traffic, and other potential nuisance conditions for residents are minimized.

The design shall ensure that the residential units are of a residential character, and that appropriate privacy between residential units and other uses on the site is provided.

Site planning and building design shall provide for convenient pedestrian access from the public street into the nonresidential portions of the project, through such means as courtyards, plazas, walkways, and street furniture.

Site planning and building design shall be compatible with and enhance the adjacent and surrounding residential neighborhood in terms of building design, color, exterior materials, landscaping, lighting, roof styles, scale, and signage.

5-6.05

Site layout and project design standards.

The minimum acreage for a PD request shall be two (2) acres.

Each PD District shall establish regulations deemed necessary and appropriate for the development of the property within the district and the protection of neighboring properties. These regulations may include, but are not limited to, the following:

Front, side, and rear yard requirements;

Minimum lot width, depth, and area requirements;

Maximum lot coverage;

Maximum building size and/or height;

landscaping, open space, and screening requirements;

Off-street parking and loading requirements; and

Signage requirements.

Loading areas.

Commercial loading areas shall be located away from residential units and shall be screened from view from the residential portion of the project to the maximum extent feasible.

Refuse and recycling areas.

Areas for the collection and storage of refuse and recyclable materials shall be located on the site in locations that are convenient for both residential and nonresidential uses.

Laundry facilities.

Each residential unit shall be provided access to laundry facilities.

Open space.

A minimum of 30 percent of the gross platted area shall be open green space. Open green space is defined as and limited to common areas of open space or landscaping and community recreational areas that is irrigated and continuously maintained. Open green space does not include areas specifically designated or used as parking lots, garages, streets, or driveways.

Lighting.

Lighting for commercial uses shall be appropriately shielded to limit impacts on the residential units.

Noise.

Each residential unit shall be designed and constructed to minimize nonresidential project noise levels, in compliance with the City's Noise Ordinance.

5-6.06

Area Regulations.

All tracts approved for PD Districts shall be provided with a sewage system meeting the standards of the City Subdivision Ordinance for conveying sewage to the City treatment plant.

Wiring, fixtures, equipment and appurtenances of every electrical wiring system shall be installed and maintained in accordance with applicable codes and regulations for such systems. All distribution and service lines of electrical, telephone, television, and other wire-carrier type utilities shall be underground, except that the system of supply lines for multiple subdivision service by utilities may be overhead. Transformers, amplifiers, or similar devices associated with the underground lines shall be located upon the ground or below the ground level. Where the underground installation of such facilities is not a standard practice of the utilities involved, the subdivider or developer shall make all arrangements for payments associated with the nonstandard installation.

A system for the storage, collection and disposal of refuse will be conducted so as to create no health hazards, rodent harborage, insect breeding areas, accident or fire hazards, or air pollution.

Natural gas piping systems shall be installed underground and maintained in accordance with applicable codes and regulations governing such systems. Piped gas shall have a cap on the outlet when not in use to prevent accidental discharge of gas, and shall be in accordance with applicable City codes. Liquefied petroleum gas systems shall not be installed in PD Districts.

Provision for an adequate, safe and potable supply of water shall be made by the owner or agent either through the development of an on-site source or purchase from the City. Each PD development shall have one single commercial water meter from the City, regardless of distribution among the business tenants, unless separate meters are deemed necessary by the public works department.

All water mains shall be six (6) inches or larger to the point of takeoff for any buildings.

Fire hydrants shall be provided by the owner or agent and shall be located so that no structure or portion of structure will be more than 500 feet from the hydrant measured along streets or driveways.

All walls separating business entities shall have a minimum fire resistance rating in accordance with the adopted Building Code of the City.

Each tenant space shall have installed and maintained, by the owner or agent of the planned center, both smoke and heat detection equipment approved by the fire marshal.

All streets and parking lots must be paved, as a minimum, according to City specification, or according to any additional specifications as may be set forth by the public works department in the interest of public safety and convenience. Pervious pavement systems are encouraged as a drainage/sedimentation control mechanism.

All telephone service lines shall be installed underground.

Each tenant space, whether by original design or by subsequent alteration, division or partitioning, that will be open to the public for sales or service, shall have installed separate toilet facilities for men and women in accordance with the laws of the state.

In reviewing the PD District and preliminary and/or development plan, the City Council will consider proposed standards for land uses, maximum height, floor area ratios, density, minimum off-street parking and loading, setbacks, site coverage, building spacing, access, screening walls or landscaping, building area, open space, pedestrian ways, public or private streets, alleys, and other development and protective requirements necessary to protect the health, safety and general welfare and to create a reasonable transition from property adjacent to a PD District. Such standards shall be specified in the ordinance establishing the zone, and in the preliminary plan and the development plan. Any PD development proposal shall be submitted to city staff for review of proposed standards at least 15 days prior to presentation of the proposal to the Council.

The minimum lot width of all lots shall be measured from side property line to side property line along the right-of-way of the primary street providing access to the lot. A site's primary, side and service street frontages shall be designated by the Administrator.

5-7.02

Setbacks.

No part of a setback or other open space required for any structure or use for the purpose of complying with the provisions of this development code may be included as a part of a setback or other open space similarly required for another structure or use.

Front, Side Street, and parking setbacks are measured from the edge of the right-of-way. Interior side setbacks are measured from the side property line. Rear setbacks are measured from the rear property line or the edge of the right-of-way if there is an alley.

An architectural feature, including an attached deck, landing, porch, stairway, balcony, bay window, cornice, eave, awning, or roof overhang may extend beyond the wall of the structure a maximum of 5 feet into a required front, side, or rear setback.

A required setback area shall not be occupied by structures other than fences, walls, and screening permitted by Article 6, Site Development Standards[.]

5-7.03

Encroachments.

The following allowed encroachments apply to all required setbacks unless otherwise stated, so long as they do not extend into any easements. Structures below and covered by the ground may extend into any required setback.

Chimneys, flues or smokestacks may encroach a maximum of two feet.

Building eaves, or roof overhangs may extend up to two feet; provided that such extension is at least three feet from the property line, its lower edge is at least 7-1/2 feet above the ground, and it is located at least five feet from my other building or eave.

Bay windows, entrances and similar features that are less than 10 feet wide may extend up to 3-1/2 feet but must remain at least five feet from the property line.

Cornices, belt courses, sills, buttresses, or other similar architectural features may project up to two feet.

5-7.04

Height.

Structure Height.

Structure height is measured in both number of stories and feet from the average grade to the top of the highest point of the roof.

A basement with 50 percent or more of its perimeter wall area surrounded by natural grade is not considered a story. An attic is not a story where 50 percent or more of the attic floor area has a clear height of less than 7-1/2 feet; measured from the finished floor to the finished ceiling.

Average grade is determined by calculating the average of the highest and lowest elevation along natural or improved grade (whichever is more restrictive) along the front of the building parallel to the setback line.

Exceptions.

The following accessory structures may exceed the established height limits, provided they do not exceed the maximum building height by more than 12 feet:

Amateur communications tower;

Cooling tower;

Clerestory;

Chimney and vent stack;
