The City's water quality and supply is maintained by the Water Division, a department within the Sierra Madre Public Works. By providing consistently high quality service to the residents of Sierra Madre we can ensure a safe and reliable method of water delivery for all users. We continue to look for ways we can improve and maintain the City's water infrastructure.

The Water Division has two sources by which they pump, treat, and distribute water. One source of the water supply is derived from four wells drawing from the East Raymond Basin aquifer. The second source is derived from two natural spring tunnels located in our foothills.

Street Tree Palette - The City's list of trees that are approved for planting in public areas in Sierra Madre. The Tree Advisory Commission regularly reviews the Street Tree Palette and makes ongoing additions or changes. The selections are based on factors such as whether the species is native to the area and would thrive in our climate, its relative drought tolerance, growth patterns in relation to providing shade and clearance over streets and sidewalks, the nature of the root growth and its propensity to damage curbs or sidewalks, and general aesthetics and consistency with the existing urban forest.
