AZ SB1680

Adds a requirement that land used for grazing or general agricultural purposes must qualify as agricultural property under Arizona tax code (Title 42, Chapter 12, Article 4) to be exempt from county zoning regulations.

Maintains the existing exemption from county zoning for railroad, mining, metallurgical, grazing, or general agricultural purposes on tracts of five or more contiguous commercial acres, but with the new agricultural property qualification for grazing and agricultural uses.

Makes technical formatting changes throughout the statute, including updating "per cent" to "percent" and adding clarifying language such as "that are" in existing provisions.

Preserves all other existing exemptions and regulations, including those for agricultural composting, firearm discharge, aggregate mining operations, and nonconforming business uses.
