Setback Requirements for the Mesa PS: Public and Semi-Public District
In the Mesa PS: Public and Semi-Public district, building setbacks are primarily determined by the classification of the adjacent street and the specific zoning of neighboring properties. Front and street-facing side setbacks range from 20 to 30 feet depending on road type, while interior side and rear setbacks range from 15 to 25 feet, or 15 feet per story for multi-story buildings [Table 11-10-3].
Development Standards for the Mesa PS District
The City of Mesa utilizes a graduated setback system for the PS: Public and Semi-Public district to ensure compatibility between large-scale governmental or institutional uses and the surrounding community. These standards apply to all facilities owned, leased, or operated by government agencies or school districts within the PS district [Section 11-10-2].

For any property in the PS: Public and Semi-Public district, the minimum front yard and street-facing side yard requirements vary according to the Mesa Transportation Plan's street classifications.

Supplemental Buffer and Screening Requirements
The City of Mesa requires additional protections when PS: Public and Semi-Public district uses are located next to residential areas.
- Buffer Yards: If a lot in the PS district abuts a lot in a Residential Single-Family (RS) or Downtown Residence (DR-1) district, a landscape buffer with a minimum width of 15 feet must be provided on the PS-zoned property [Section 11-10-3(A)].
- Screening Walls: A screening wall with a height of 6 feet is mandatory whenever a lot in the PS district abuts any "R" (Residential) or "DR" (Downtown Residential) district at the time of development [Section 11-10-3(A)].
- Building Separation: When multiple buildings are located on the same lot within the PS district, they must maintain a minimum separation of 25 feet for one-story buildings, 30 feet for two-story buildings, and 35 feet for buildings with three or more stories [Table 11-10-3].
