The city has established, through provisions within its general plan, that urban trees contribute not only scenic beauty, but that they reduce soil erosion, improve air quality, provide wind protection, abate noise and offer shade to reduce energy consumption.

The city has further established that certain heritage and landmark tree resources exist within the city which by the nature of their physical, social, or environmental significance or contribution to the identity of neighborhoods, merit community recognition and protection.

It is therefore the intent and purpose of this chapter to promote the health, safety and welfare of present and future residents of the city of Petaluma by providing for the identification and preservation of heritage and landmark tree resources existing within the city.

It is further the intent and purpose of this chapter to encourage cooperative neighborhood efforts toward preservation of groups of trees located on publicly or privately owned lands which collectively contribute to a unique and attractive living environment for residents.
