How Tucson Handles Tree Protection: A Practical Guide

Tucson maintains 147 local ordinances across all categories, and 2 of those deal specifically with tree protection. Here is a breakdown of what the city actually requires, what is prohibited, and where Tucson falls on the strict-to-permissive spectrum compared to other cities.

Protected Tree Species

Before grading any site, Tucson developers must preserve 100% of federal endangered species and "crested" Saguaros, at least 50% of viable Saguaros and Ironwoods, and 30% of other protected native plants under an approved Native Plant Preservation Plan, with no exceptions for convenience.

Key details: Endangered species/crested Saguaros: 100% must be preserved or salvaged. Viable Saguaros & Ironwoods: At least 50% preserved or salvaged. Other protected native plants: At least 30% preserved or salvaged. Saguaro removal fine: $200/ft of trunk & arm, max $2,500. Tree/shrub removal fine: $300/caliper inch, max $2,500.

Section 10.4.5.A fines anyone who intentionally or negligently damages, destroys, or removes a protected plant without an approved plan: for each viable Saguaro, $200 per foot of trunk and $200 per foot of each arm, capped at $2,500; for each protected tree or shrub, $300 per caliper inch up to $2,500; for other cacti or succulents, $300 per specimen up to $2,500. Removal before a plan is even approved draws a flat $500-$2,500 fine. The PDSD Director can also order mitigation, up to eight years of monitoring, and immediate suspension or revocation of building permits, appealable through PDSD's established procedures, and record the suspension against the property with the Pima County Recorder.

This is not one of those rules that cities tend to ignore. Tucson actively enforces its protected tree species requirements.

Parkway Planting

Planting a tree, shrub or other vegetation in the parkway strip between the curb and sidewalk in Tucson requires a written permit from the city engineer. Sec. 25-52.1 sets species lists, sight-visibility height limits, and a minimum four-foot planting strip.

Key details: Permit issuer: City engineer / development services center. Minimum planting strip width: 4 feet, curb to sidewalk. Height cap near intersections: 30 inches within 50 ft of stop/yield sign. Clear zone for sight lines: 30 to 80 inches above ground. Species source: City low-water-use street tree list.

Planting in the pedestrian right-of-way without a permit, or violating the height/sight-visibility standards, allows the city to revoke any permit issued and remove the vegetation without compensating the owner. Failure to maintain plantings as required, or a city need for the space, also triggers revocation and removal under Sec. 25-52.1(6)(b).

The Bottom Line

Tucson'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 Tucson is broadly strict or permissive.

Keep in mind that Tucson can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
