(2) Existing native, non-invasive and drought tolerant trees having a diameter of aoe foot 24 inches or greater, as measured at diameter breast height (dbh), shall not be cut, damaged or destroyed within a secondary tree protection area except as shown on an approved Landscape and Tree Preservation Plan, plot plan, or site plan . (3) During construction activities, adequate protective measures shall be provided to minimize damage to existing trees and other vegetation. (4) All tree protection fencing shall be installed prior to any grading, construction traffic or activity taking place on site. (5) Logging mats shall be used in areas where drip lines or critical root zones may be disturbed during construction. (6) Signs in English and Spanish shall be posted identifying the tree protection areas and shall state the area is not to be disturbed. Such protective devices shall effectively protect the critical root zones, trunks, and tops of trees to be retained and shall be maintained until all work has been completed.

Fertilize, if necessary and water the undisturbed root area of the tree; (4) Trees that are marked for preservation and for which utilities must pass through their critical root zones shall not have surface-dug trenches; and (5) Utilities shall be bored through critical root zone areas.
