Alameda County Permit Portal

Unincorporated Alameda County has approximately 280,168 acres in which substantial portions were and are covered by native, indigenous and historical trees. The County recognizes that the preservation of these trees and our urban forest enhances the natural scenic beauty, sustains the long term potential increase in property values, which encourages quality development, maintains the ecology, moderates the effect of extreme temperatures, prevents the erosion of topsoil, helps create an identity and quality, which enhances the attractiveness of the County to visitors and increases the oxygen output of the area which is needed to combat air pollution. For these reasons the Alameda County Board of Supervisors finds that in order to promote the public health, safety and general welfare of the County while at the same time recognizing individual rights to develop and maintain private property in a manner which will not be prejudicial to the public interest it is necessary to enact regulations controlling the planting, pruning and removal in order to preserve trees within the County right-of-way.
