Guide to the EO: Employment Opportunity District in Mesa

The EO: Employment Opportunity district in the City of Mesa is a high-quality, flexible zoning classification intended for large-scale industrial and professional developments of at least 160 contiguous acres (or 140 acres for Qualified Political Subdivisions). It functions as a floating zone where specific land uses and development standards are primarily established through a project-specific EO Development Plan approved by the Mesa City Council [Section 11-14-2].

Purpose of the EO: Employment Opportunity District

The primary intent of the EO: Employment Opportunity district in the City of Mesa is to facilitate the development of projects that attract industries providing significant employment opportunities. The Mesa zoning code emphasizes that the EO: Employment Opportunity district should accommodate large-scale, unified, and planned employment developments that remain consistent with the goals of the Mesa General Plan [Section 11-14-1].

Key objectives include:

Providing flexibility to accommodate market changes while maintaining high-quality design [Section 11-14-1].
Ensuring developments fit into the context of the area and provide effective transitions between abutting parcels [Section 11-1-2].
Promoting unified, mixed-use development on lands owned by political subdivisions of the State of Arizona [Section 11-14-1].

General Character and "Floating Zone" Status

The EO: Employment Opportunity district is unique in the City of Mesa because it can be established as a "floating zone." This means the City Council may approve the EO: Employment Opportunity district over a property while retaining the existing zoning as the "active" district until a property owner chooses to "opt-in" [Section 11-14-2].

Once a property owner opts into the EO: Employment Opportunity district, the property must be developed according to an approved EO Development Plan. This plan serves as the principal reference for the boundary, land use groups, and development standards of the site [Section 11-14-3]. The general character is intended to be campus-like, with professional office parks, research facilities, and light manufacturing integrated with supportive establishments like restaurants [Section 11-7-1].

Permitted Land Uses

In the EO: Employment Opportunity district, permitted, conditional, and prohibited land uses are specifically listed in the individual project's EO Development Plan. If a proposed use is not explicitly listed in that plan, it is prohibited unless the Zoning Administrator determines it is equivalent to a permitted use [Section 11-14-3].

Commonly associated uses for this district classification in the City of Mesa include:

Employment and Industrial: Research and development, light assembly, manufacturing, and data centers [Section 11-7-1, Section 11-31-36].
Office and Professional: Medical offices, professional business centers, and administrative services [Section 11-7-1].
Supportive Uses: Small-scale commercial, retail, and services intended to support the primary employment base [Section 11-14-3].
Residential: Mixed-use residential components may be permitted if specified in the approved EO Development Plan [Section 11-14-3].

Development Standards

Because the EO: Employment Opportunity district relies heavily on individual development plans, many standards are "Plan Specific." However, the City of Mesa establishes the following baseline requirements for employment-related districts:

Design and Amenity Requirements

The City of Mesa requires that developments in the EO: Employment Opportunity district demonstrate "Superior Design." This includes a holistic approach to project design using high-quality materials and architectural elements that provide interest and variety [Section 11-31-32].

Specific design standards include:

Wall Articulation: Publicly visible facades may not have blank, uninterrupted wall lengths exceeding 50 feet without changes in plane, texture, or the inclusion of windows [Section 11-7-3].

Data Center Requirements: Data centers in the EO: Employment Opportunity district are subject to rigorous sound mitigation standards and water consumption reporting to ensure they do not negatively impact surrounding residential areas [Section 11-31-36].
