How Tempe Handles Tree Protection: A Practical Guide

Tempe maintains 119 local ordinances across all categories, and 3 of those deal specifically with tree protection. Here is a breakdown of what the city actually requires, what is prohibited, and where Tempe falls on the strict-to-permissive spectrum compared to other cities.

Tree Removal Permits

Trees on private residential property in Tempe can generally be removed without a city permit unless they are protected native species under ARS 3-901. Protected species (saguaro, palo verde, ironwood) require an Arizona Department of Agriculture permit. City street trees cannot be removed by residents. New development must include tree preservation in landscape plans.

Key details: Private Non-Protected: No city permit generally needed. Protected Native: AZ Dept of Agriculture permit required (ARS 3-901). City Street Trees: Cannot be removed without authorization. Neighbor's Trees: May trim branches to property line. Development: Landscape plan must address existing trees.

Unauthorized removal of protected native plants carries state penalties up to $100,000. Removing city street trees may require replacement at the owner's cost.

Heritage & Protected Trees

Tempe protects significant trees through its landscape standards in the Zoning and Development Code. Arizona's Protected Native Plant Law (ARS 3-901) protects native desert trees statewide. During development review, Tempe requires tree preservation plans for significant existing trees. Mature shade trees are increasingly valued for urban heat island mitigation.

Key details: State Law: ARS 3-901 (Protected Native Plant Law). Development Review: Tree preservation plans may be required. Native Species: State permit required for removal. Street Trees: City managed, no unauthorized removal. Heat Island: Trees valued for cooling urban areas.

Removing protected native plants without a state permit carries fines up to $100,000. Unauthorized removal of city street trees may result in replacement costs.

Tree Replacement Requirements

Tempe's Zoning and Development Code requires tree replacement when significant trees are removed during development. The city values shade trees for urban heat island mitigation. Replacement trees should be desert-adapted species from the approved plant list. The city's urban forestry program works to increase canopy cover across Tempe.

Key details: When Required: During development when significant trees removed. Ratio: May exceed 1:1 for large/mature trees. Species: Desert-adapted from approved plant list. Priority: Shade trees for heat island mitigation. Street Trees: Must be replaced at owner's expense if damaged.

Failure to replace trees as required in development conditions may hold up project completion or certificate of occupancy.

The Bottom Line

Tempe's tree protection rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Tempe is broadly strict or permissive.

These rules come from Tempe's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
