The Forestry Section of the Public Works Operations Division is responsible for the management of trees located in the public rights-of-way. These trees, referred to as street trees, are typically located in the medians, between the curb and sidewalk, or adjacent to the curb for those areas without sidewalks. The Forestry Section trims street trees on a priority-based trimming schedule. Trees not included in this year's tree trimming list, but noted by city crews for having possible hazardous limbs, low-hanging limbs, or limbs brushing properties, will be addressed based on the assessment of one the departments certified foresters.

Public Works/Parks Tree Inventory

A citywide tree inventory was recently completed. Davey Resource Group, a division of The Davey Tree Expert Company, conducted the comprehensive inventory and assessment of nearly 11,000 trees and potential planting sites on public streets and parks. The project is part of ongoing efforts within Clayton to better manage trees, minimize the effects of future storm damage, place a monetary value on the tree canopy and ensure the community has a healthy, sustainable urban forest. A Certified Arborist assessed the condition, stability, and value of each tree. Reducing risk is a primary objective in completing the assessment. The City has uploaded the inventory data into the City’s GIS system. The plan is to use the inventory to better improve the efficiency of the tree maintenance programs on the street and in the parks, as well as overall improvement of the City’s urban forest management program. Half of this project was paid for through a TRIM grant from the Missouri Department of Conservation.

Right Tree/Right Location

The City is taking advantage of Ameren's Right Tree/Right Location Program.

The Forestry Section then replaces them with appropriate under-story trees, which are financially subsidized by Ameren.
