A. Purpose. The DO is an overlay designation identifying geographic areas where owners of land may opt to replace their underlying zoning entitlements with the DN and DT zone designations.
B. Application. To obtain DN and DT zoning in the DO district, one or more property owners must submit a downtown implementation plan, showing (at a minimum) the requested locations of DN and DT zone designations on their property.
C. Administrative approval. The planning manager is authorized and directed to approve a downtown implementation plan that conforms to the requirements of sections 17-4-9 (Mixed-use zoning districts), 17-4-12 (Downtown Marana overlay (DO)), 17-4-13 (Downtown neighborhood (DN)), and 17-4-14 (Downtown (DT)), and meets the following minimum requirements:
1. The DT designation includes all land within 100 feet of the Marana Main Street right-of-way line.
2. The DN designation includes all land within 100 feet of the property line of all properties containing existing single-family residences, excluding any such property for which the property owner consents in writing.
3. The DN designation must be used for land that meets both of the previous two paragraphs.
D. Council approval. Any downtown implementation plan not approved pursuant to paragraph C of this section may be submitted as an application for rezoning, which shall be reviewed through the normal rezoning process.
Ordinance 2024.010 amended paragraph C, removed paragraphs D and E, and renumbered paragraph F
A. Purpose. The DN zone implements the Marana general plan by providing a transition from the DT to surrounding areas. This zone consists of a mix of uses but is primarily medium density residential. It may contain a wide range of building types: houses, courtyard housing, townhouses, duplexes, triplexes, apartment buildings, and live-work units.

A. General. Properties in each specific plan (SP) zoning district are regulated based on site-specific regulations prepared by or on behalf of the master property owner of the particular specific plan area. Each specific plan is adopted through the rezoning process set forth in section 17-3-1.
B. Applicability. The owner or owners of one or more contiguous parcels of land totaling five acres or larger in size may apply for a specific plan.
C. Contents of specific plan. All specific plans shall include the requirements defined in the town's applications, checklists, and process guides on file with the development services department. At a minimum, a specific plan shall include the following elements:
1. Narrative or overview of the project which identifies the primary objectives.
2. Development capability inventory analysis.
3. Proposed land use plan.
4. Implementation and administrative regulations.
5. Development and design regulations.
6. The compatibility of the specific plan with adjoining land uses.
7. Detailed regulations and programs for the systematic implementation of the specific plan.

14. For single-phase plans, a draft schedule for the preservation of site features established by the plan and the construction, dedication and provision of public services.
15. For multi-phased plans, a draft phasing schedule for the preservation of site features established by the plan, the development of the various master blocks of the specific plan, and the construction, dedication and provision of public services.
16. How and to what extent the specific plan is to supplement or supersede the adopted land development code.
D. Specific plan amendments. Amendments to specific plans are categorized as either administrative amendments or substantial amendments. Administrative amendments are approved by the planning manager after written application is made. Substantial amendments are approved through the rezoning process set forth in section 17-3-1.
1. The planning manager shall determine whether a proposed specific plan amendment is administrative or substantial.
2. Categories of administrative amendments include, but are not limited to:
a. The addition of new information to the specific plan maps or text that does not change the effect of any regulations or guidelines.
b. Changes to infrastructure, such as drainage and utilities, which do not change the overall intent of the specific plan or increase the development capacity in the specific plan area.
c. Changes in the land use designation boundary, division of plan areas or combinations of areas.
d. Minor modifications or adjustments to intrusions, encroachments, easements, rights-of-way, or open spaces, so long as the modifications do not conflict with the overall intent of the specific plan.
e. The addition of a use that is materially similar to a listed use, as determined by the planning manager pursuant to the process set forth in section 17-4-2(C).
3. A substantial amendment is an amendment that would result in a substantial change to the specific plan's regulations or the overall intent of the specific plan, and that is not an amendment listed in subparagraph 2 above or a materially similar amendment.
A. The zoning districts set forth in sections 17-4-17 through 17-4-26 below are legacy zones. The legacy zones consist of zoning districts that currently exist within the town limits, but that are intended to be phased out over time. Each of these zoning designations is intended to be deleted when no land in the town has that zoning designation. The town will not rezone land to any of these legacy zone districts.
B. Notwithstanding any language in sections 17-4-17 through 17-4-26 permitting commercial and industrial uses in the legacy zones, as provided in section 17-6-13, data centers are not permitted to operate in the town as a principal use unless approved in a specific plan or specific plan amendment explicitly created or amended for the purpose of data center development and adopted through the rezoning process set forth in section 17-3-1 and as described in section 17-4-15 (Specific plan (SP)).
C. Data centers are permitted as an accessory use in the legacy zoning districts when all of the following are true:
1. The data center occupies no more than 15% of the site.
2. The data center is used to serve the enterprise functions of the on-site property owner and is not used to lease data storage and processing services to third parties. For purposes of this subparagraph "on-site property owner" includes an owner that owns the property and is the parent company of the company or companies on-site.
3. The data center complies with any applicable development standards for accessory use data centers, as set forth in section 17-6-13.
Ordinance 2024.029 added paragraphs B. and C. to section 17-4-16.
A. Permitted uses. Within zone A, residential, commercial, industrial, and quasi-public land uses shall be permitted so long as each such land use is conducted on a lot no larger than 2.5 acres. Agricultural uses, as listed in section 17-4-2, table 2 (Use matrix), shall be permitted in zone A in the same circumstances as they are permitted in the AG zone per section 17-4-2, table 2, and subject to the same conditions per use as in the AG zone per section 17-4-3, table 3 (Conditions per use). Rezoning is not required to establish a use permitted in the neighborhood commercial (NC) zone, within an existing building or suite in a designated commercial area if the use can be accommodated within the existing building or suite without requiring a new retail commercial building permit. This is not, however, to be construed to permit any land use that may be specifically prohibited within the town by this or any other ordinance of the town or by state or federal law.
B. Density requirements. There shall be no maximum density of land use per se, except that density of land use on any parcel of land within zone A shall be determined in part by prior density of land use and by setback requirements defined in this and other titles of this code or as may be determined by other applicable federal, state and local regulations.
C. Setbacks.
1. The required front yard (setback) shall be a minimum of 20 feet.
2. The required side yard (setback) shall be a minimum of five feet, with a street side yard (setback) having a minimum of ten feet.
3. The required rear yard (setback) shall be a minimum of 20 feet.
D. Building heights. Buildings and structures erected in this zone shall have a height not greater than 30 feet.
E. Manufactured home. A manufactured home may be placed on any lot within zone A provided the following conditions are met:
1. There is an existing manufactured home on the lots adjacent to the lots in which the new manufactured home is to be placed. Adjacent, for the purposes of this section, means on either side, and means directly across the street, if one exists, and to the rear across an alley, if one exists.
2. Where the provisions of subparagraph 1 above do not exist, then a manufactured home may be placed on a lot with the issuance of a conditional use permit pursuant to the procedure set forth in section 17-3-2 (conditional use permits).
Ordinance 2022.006 amended Section 17-4-17 A.
A. Permitted uses. Within zone B, any residential, commercial, industrial, or quasi-public land use is permitted so long as each separate land use is conducted on a lot larger than 2.5 acres but no larger than 25 acres. Agricultural uses, as listed in section 17-4-2, table 2 (Use matrix), shall be permitted in zone B in the same circumstances as they are permitted in the AG zone per section 17-4-2, table 2, and subject to the same conditions per use as in the AG zone per section 17-4-3, table 3 (Conditions per use). This is not to be construed, however, to permit any land use that may be expressly prohibited within the town by other ordinances of the town, by other provisions of this code, or by state or federal law.
B. Density requirements. There shall be no maximum density of land use per se in this zone, except as may be dictated by prior density of land use and by setback requirements defined elsewhere in this code.
C. Setbacks. The setback requirements for zone B shall be the same as for zone A.
D. Manufactured home. A manufactured home may be placed on any lot within zone B provided the following conditions are met:
1. There is an existing manufactured home on the lots adjacent to the lots in which the new manufactured home is to be placed. Adjacent, for the purposes of this section, means on either side, and means directly across the street, if one exists, and to the rear across an alley, if one exists.
2. Where the provisions of subparagraph 1 above do not exist, then a manufactured home may be placed on a lot with the issuance of a conditional use permit pursuant to the procedure set forth in section 17-3-2 (conditional use permits).
Ordinance 2022.006 amended Section 17-4-18 A.
