As a "Tree City USA," the City values trees as a community asset. The City provides trees in neighborhoods (within the public right-of-way) for aesthetics, shade, wind protection, and to help absorb pollutants in the air. While the City maintains these trees by trimming within a specific maintenance cycle, residents are asked to help provide regular irrigation to support the health of these trees. Trees need a good water supply to help produce sap to defend against boring pests. Of course, watering of trees and landscaping irrigation in general, should be monitored to prevent over-watering and run-off especially in the current drought situation.
For tips on watering and maintaining trees, see the following links to the Tree Preservation and Protection Guidelines as well as City ordinances for trees on public property and private property.
