(a) All public trees located near excavation or construction of any building, structure, or street work, shall be guarded with a high visibility orange safety fence, at least four feet in height, properly staked and placed to protect the CRZ. All laborers, building material, dirt or other debris shall be kept outside this barrier. The Shade Tree Commission may permit a variance in cases where the barrier would impede the flow of traffic on a street, private street or driveway and where the dripline overhangs a building or permanent structure.
(b) No person shall excavate any ditches or trenches within the dripline of a public tree or lay any drive within fifteen feet of a public tree without first obtaining the written approval of the Shade Tree Commission or the Street Superintendent.
