It is declared that the public interest and welfare require that the City establish a program for the preservation of oak trees and significant trees in order to maintain the heritage and character of the City of Oakdale as well as preserve the beauty and identity of the community. Toward this purpose, this section establishes regulations for the installation, preservation, protection and selected removal of trees within the City limits. In establishing these procedures it is the City's intent to preserve and encourage the regeneration of a healthy urban forest that contributes to clean air, soil conservation, aesthetics, enhanced property values and a quality of life that will ensure that Oakdale will continue to be a desirable place to live.
