City Arborist outlines streamlined tree removal permit process for residents and developers

The South Pasadena Public Works Infrastructure Commission convened on June 11, 2025, to discuss significant updates to the city's tree removal and replacement ordinance. The meeting focused on streamlining the process for tree removal, particularly in light of development projects such as accessory dwelling units (ADUs).

One of the primary topics was the proposed reduction in tree replacement requirements. Currently, the ordinance mandates that for every tree removed, a certain number of trees must be replanted. The commission is considering lowering this requirement, especially for hazardous or dead trees, to just one native tree. This change aims to make the process more manageable for property owners, particularly those involved in development, where the replacement requirement can be as high as 30 trees for a single lot.

The commission also discussed the role of a contracted arborist in the tree removal process. While the city does not currently employ a full-time arborist, they have a contracted professional who assesses tree removal applications. The commission is exploring the possibility of hiring a full-time arborist in the future to ensure consistency in evaluations and decisions regarding tree removals.

Another key point of discussion was the need for clearer guidelines regarding tree trimming. The current ordinance states that property owners cannot trim more than 10% of a tree's live foliage without a permit. The commission plans to provide clearer language and educational resources to help residents understand when a permit is necessary for trimming.

The meeting also addressed the permit process's workload, which has been described as significant. The city arborist conducts inspections twice a month, and the process can take several months due to the required notifications and potential appeals. The commission aims to streamline this process to reduce wait times for residents.

In conclusion, the proposed updates to the tree ordinance reflect the commission's commitment to balancing environmental stewardship with the needs of residents and developers. The next steps will involve drafting the ordinance updates and seeking final approval from the city council.
