Reducing outdoor water use has several benefits. Using less water to irrigate landscapes reduces the amount of runoff entering the stormwater system, improves regional water quality, reduces energy and utility costs, and improves biological resources. 

In addition, reducing outdoor water use also contributes to greenhouse gas emissions reductions associated with the treatment and delivery of water to homes in the unincorporated county. Through the adoption of this update to the Landscape Ordinance, it is estimated that 17,535 metric tons of greenhouse gas emissions will be reduced through implementation of water conservation requirements included in the updated ordinance by 2030.

The updated Landscaping Ordinance also includes a new tree planting requirement for single-family residences.

For each new single-family unit constructed, a minimum of two trees will be planted to facilitate carbon sequestration in the unincorporated county.

An additional water allowance will be granted to these projects to aid in the establishment of the trees, however there will be a net greenhouse gas benefit from implementing this requirement. In fact, it is estimated that through implementation of this requirement, 1,735 metric tons of greenhouse gas emissions will be reduced by 2030.

Planting trees in residential settings also improves biological resources, can improve the energy efficiency of homes, and improves soil health on the property.
