Ask the City Arborist by emailing An ISA Certified Arborist is trained to understand the needs of trees and provide the care and maintenance necessary to enhance a tree's health, beauty, and structural soundness.

Rancho Cordova’s urban forest provides many economic, health and environmental benefits for City residents and businesses: 
• One large tree can provide a day’s supply of oxygen for up to four people.
• Trees remove pollution from the atmosphere, improving air quality and human health.
• Trees lower surface and air temperatures by providing shade.
• During one year, a mature tree will absorb more than 48 pounds of carbon dioxide from the atmosphere and release oxygen in exchange.
• Nearly 20 pounds of carbon dioxide is produced from burning one gallon of non-ethanol gasoline. 
• A cost-benefit analysis of the Rancho Cordova tree canopy indicated that the City-maintained trees are worth an estimated $7.3 million.
• Healthy mature trees increase property values.

You can calculate the benefits of trees on your property or the right-of-way by using the National Tree Benefit Calculator.

The City of Rancho Cordova’s goal is to continue to enhance our urban forest, protecting its health and diversity, and ensuring it provides benefits for future generations.
