Intent. This cluster option, to be used in the GR zone only, provides for:

1.

The voluntary, permanent conservation of open space as a product of the subdivision of land;

2.

The protection of natural features including riparian areas, rock outcrops and natural topography; and

3.

Flexibility in designing residential developments while not exceeding standard general rural (GR) residential densities.

B.

Purpose. The purpose of the cluster option in the GR zone is to:

1.

Preserve significant, natural open space areas and cultural resources without increasing overall residential densities.

2.

Encourage and provide incentives for innovative site planning that is harmonious with the natural features and constraints of property.

3.

Support open spaces that are interconnected, continuous, and integrated, particularly when located contiguous to public preserves.

4.

Allow for design innovation, flexibility, and more cost-effective development due to more efficient servicing of the development with utilities, roads and other services.

5.

Provide additional usable open space.

C.

Definitions. The following words, terms and phrases, when used in this section, shall have the meanings ascribed to them in this subsection, except where the context clearly indicates a different meaning:

Functional open space means a designed element of the subdivision that has a functionally described and planned use as an amenity for the direct benefit of all the residents of the subdivision. Functional open space is equally accessible to all residents of the subdivision. Examples of functional open space include, but are not limited to, landscaped areas which provide visual relief, shade, screening, buffering and other environmental amenities; nature trails; exercise trails; playgrounds; picnic areas and facilities; recreation areas and facilities. The term "functional open space" does not include indoor facilities, public or private streets, driveways, parking areas, or channelized/altered drainage ways.

Natural open space means any area of land, unimproved except for pedestrian and nonmotorized access trails, that is set aside, dedicated or reserved in perpetuity for public or private enjoyment as a preservation or conservation area.

Open space means those areas of either functional or natural open space (as defined herein), of the subdivision that are permanently designated and deed restricted to open space.

Primary conservation features means those parts of the site that contain primary resource value natural features such as lakes, ponds, wetlands, floodways, riparian areas, prominent peaks and ridges, prominent rock outcrops, slopes over 15 percent, prominent vegetative and geologic features including saguaros, ironwoods, mesquite bosques, and habitat for threatened and endangered species.

Private living area means the portion of a lot occupied by buildings, walls, patios, permitted accessory uses, vehicular parking, circulation areas, and connecting pedestrian walks.

Restored, restoration, or mitigation means the process of repairing a previously disturbed area or graded site feature and replicating its previously undisturbed, or ungraded condition of vegetation, plant communities, geologic structures, grade, drainages, and riparian area that historically existed on the site. Restoration includes revegetation, and may include corrective grading, natural and artificial rock, and top dressing.

Wildlife friendly fencing means a maximum 42-inch-high fence using two-strand, nonbarbed, 12-gauge wire and T-posts as installed and maintained, with the bottom strand being no less than 18 inches from the ground. Other specifications shall be in accordance with Arizona Game and Fish Department standards for wildlife friendly fencing.

D.

Applicability. These cluster standards may be used to allow development on land containing natural features while permanently conserving substantial amounts of valuable open space. The GR cluster option is only to be applied to land that contains natural features such as desert washes, riparian areas, prominent peaks and ridges or natural slopes over 15 percent, and shall not be applied to agricultural lands where natural features have been removed such as farm fields. The cluster option can only be used in conjunction with the application for a subdivision plat submitted and processed in accordance with the Pinal County zoning ordinance and other regulations. This cluster option shall not be used in conjunction with a planned area development (PAD) application. Except as noted in this section, all other requirements of the Pinal County zoning ordinance shall apply.

4.

Except where protection of sensitive natural resources is paramount, convenient access to the open space areas of the subdivision shall be provided for all residents with multiple points for nonvehicular access. Nonvehicular access to open space will provide frequent access points making the open space amenities equally accessible to all residents of the subdivision.

5.

To maximize natural open space area benefits, open space areas shall provide connections to public preserves, undisturbed riparian areas and natural areas on adjoining properties, where appropriate.

6.

Where possible, natural open space areas shall be designed as part of a larger contiguous and integrated open space system of undeveloped areas.

7.

Within washes that have riparian habitat, only that grading for roadways and utilities that is necessary to provide access to approved development areas is permitted. Wash disturbance shall be minimized and all utilities shall be installed within utility easements, except where a utility easement is not a practical location for the utility as confirmed by the planning director, then the utility crossing shall utilize the least intrusive construction methodology. The disturbed wash area is subject to mitigation and revegetation as approved by the planning director.

8.

Graded and disturbed areas outside private living areas and fenced or walled pet runs shall be revegetated with plant material that replicates the understory, midstory and canopy of adjoining open space areas.
