Firestone City Zoning Code

CHAPTER 3

Use Regulations

Sections:


16.3.1 - Table of permitted uses.

Table 3-1 below lists the principal uses permitted within all standard zoning districts. For the PUD district, unless expressly modified in the PUD development plan, uses shall be as specified in Table 3-1 for the appropriate land use category. Each of the listed uses is defined in Chapter 11.

A.

Explanation of table abbreviations.

1.

Permitted uses. "P" in a cell indicates that the use is permitted by right, without special conditions other than those imposed upon other uses by right in the district. Permitted uses are subject to all other applicable regulations of this FDC, including the use-specific standards set forth in this Chapter and the requirements of Chapter 6.

2.

Special Review Uses. "S" in a cell indicates that, in the respective zoning district, the use is permitted only if reviewed and approved as a Special Review Use in accordance with the procedures of Section 16.7.11. Special Review Uses are subject to all other applicable regulations of this FDC, including the use-specific standards set forth in this Chapter and the requirements of Chapter 6.

3.

Prohibited uses. A blank cell indicates that the use is prohibited in the respective zoning district.

4.

Use-specific standards. Regardless of whether a use is permitted by right or permitted as a Special Review Use, there may be additional standards that are applicable to the use. Use-specific standards are noted through a cross-reference in the last column of the table. Cross-references refer to Section 16.3.2. These standards apply in all districts unless otherwise specified.

B.

Table organization. In Table 3-1, land uses and activities are classified under a "primary use classification" (such as Residential or Commercial) and then into specific "use types" based on common functional, product, or physical characteristics, such as the type and amount of activity, the type of customers or residents, how goods or services are sold or delivered, and site conditions. This classification provides a systematic basis for assigning present and future land uses into appropriate zoning districts. This classification does not list every use or activity that may appropriately exist within the categories and specific uses may be listed in one (1) category when they may reasonably have been listed in one (1) or more other categories. The use categories are intended merely as an indexing tool and are not regulatory.

C.

Use for other purposes prohibited. Approval of a use listed in Table 3-1, and compliance with the applicable use-specific standards for that use, authorizes that use only. Development or use of a property for any other use not specifically permitted in Table 3-1, and approved under the appropriate process is prohibited, unless otherwise permitted as noted below.

D.

Classification of new and unlisted uses. Notwithstanding the prohibition stated in Subsection 16.3.1.C above, new types of land use will develop and forms of land use not anticipated may seek to locate in the Town. In order to provide for such situations, a determination as to the appropriate classification of any new or unlisted form of land use shall be made. When application is made for a use category or use type that is not specifically listed in Table 3-1, the procedure set forth below shall be followed.

1.

The Director shall provide an interpretation as to the zoning classification into which such use should be placed. In making such interpretation, the Director shall consider its potential impacts, including but not limited to: the nature of the use and whether it involves dwelling unit activity; sales; processing; type of product, storage and amount, and nature thereof; enclosed or open storage; anticipated employment; transportation requirements; the amount of noise, odor, fumes, dust, toxic material, and vibration likely to be generated; and the general requirements for public utilities such as water and sanitary sewer.

2.

Standards for new and unlisted uses may be interpreted as those of a similar use by the Director.

3.

Appeal of the Director's decision shall be made to the Board of Adjustment following procedures under Subsection 16.7.20.A.

A.

Purpose. This Section authorizes the establishment of accessory uses. An accessory use is "incidental and customarily subordinate" to a principal use if it complies with the standards set forth in this Section.

B.

Approval of accessory uses and structures.

1.

All principal uses permitted in a zone district shall be deemed to include the accessory uses, structures, and activities set forth in this Section, unless specifically prohibited. In addition, Chapter 11 (Definitions), identifies typical accessory uses associated with many principal uses as part of that principal use's definition.

2.

All accessory uses shall be subject to the general standards set forth in this subsection, as well as any use-specific standards set forth in Section 16.3.2 above.

C.

Explanation of table abbreviations.

1.

Permitted uses. "P" in a cell indicates that the use is permitted by right, without special conditions other than those imposed upon other uses by right in the district. A use by right requires no further approval from the Board of Trustees; however, it shall be subject to Final Development Plan review if the associated principal use requires Final Development Plan review. Permitted uses are subject to all other applicable regulations of this FDC, including the use-specific standards set forth in this Chapter and the requirements of Chapter 6.

2.

Special Review Uses. "S" in a cell indicates that, in the respective zoning district, the use is permitted only if reviewed and approved as a Special Review Use in accordance with the procedures of Section 16.7.11. Special Review Uses are subject to all other applicable regulations of this FDC, including the use-specific standards set forth in this Chapter and the requirements of Chapter 6.

3.

Prohibited uses. A blank cell indicates that the use is prohibited in the respective zoning district.

4.

Use-specific standards. Regardless of whether a use is permitted by right or permitted as a Special Review Use, there may be additional standards that are applicable to the use. The existence of these use-specific standards is noted through a cross-reference in the last column of the table. Cross-references refer to Section 16.3.2. These standards apply in all districts unless otherwise specified.

D.

Classification of new and unlisted uses. When application is made for an accessory use category or use type that is not specifically listed in Table 3-2, the procedure described in Subsection 16.3.1.D, shall be followed.

E.

Table of permitted accessory uses. Table 3-2 below lists the accessory uses permitted within all zoning districts.

F.

General standards. All accessory uses and structures shall comply with the general standards in this Section. No accessory use shall be located on any lot as the principal use.

1.

Compliance.

a.

All accessory uses and structures shall be subject to the standards set forth in this Section, and also the use-specific standards of Section 16.3.2 above and the dimensional standards of Chapter 4. In the case of any conflict between the accessory use/structure standards of this Section and any other requirement of this FDC, the more restrictive standards shall control.

b.

Accessory uses shall comply with all standards of this FDC applicable to the principal use with which they are associated. Parking requirements shall be met for both the principal use and any accessory use.

2.

Same lot required. The accessory use or structure shall be conducted and/or located on the same lot as the principal use.

3.

Same ownership required. The property where the principal use and the accessory use are occurring shall be under the same ownership.

4.

Same utility meter required. The principal use and the accessory use shall utilize the same utility meter.

5.

Temporary accessory uses and structures. Temporary accessory uses and structures shall be governed by the temporary use permit procedures and standards set forth in Sections 16.7.14 and 16.3.4.

6.
