NO PERSON MAY CONDUCT ANY ACTIVITY WITHIN THE PROTECTED AREA OF ANY TREE DESIGNATED TO REMAIN, INCLUDING, BUT NOT LIMITED TO, OPERATING OR PARKING EQUIPMENT, PLACING SOLVENTS, STORING BUILDING MATERIAL OR SOIL DEPOSITS, OR DUMPING CONCRETE WASHOUT OR OTHER CHEMICALS. DURING CONSTRUCTION, NO PERSON SHALL ATTACH ANY POTENTIALLY HARMFUL OBJECT TO ANY TREE DESIGNATED FOR PROTECTION. B. PROTECTIVE BARRIER. BEFORE DEVELOPMENT LAND CLEARING FILLING OR ANY LAND ALTERATION THE APPLICANT SHALL: a. ERECT AND MAINTAIN READILY VISIBLE TEMPORARY PROTECTIVE TREE FENCING ALONG THE LIMITS OF DISTURBANCE TO COMPLETELY SURROUND THE PROTECTED AREA OF ALL RETAINED TREES OR GROUPS OF TREES.

TO THE GREATEST EXTENT PRACTICAL, UTILITY TRENCHES SHALL BE LOCATED OUTSIDE OF THE CRITICAL ROOT ZONE OF TREES TO BE RETAINED. THE ADMINISTRATOR OR DIRECTOR MAY REQUIRE THAT UTILITIES BE TUNNELED UNDER THE ROOTS OF TREES TO BE RETAINED IF THE ADMINISTRATOR OR DIRECTOR DETERMINES THAT TRENCHING WOULD SIGNIFICANTLY REDUCE THE CHANCES OF THE TREES SURVIVAL. e. TREES AND OTHER VEGETATION TO BE RETAINED SHALL BE PROTECTED FROM EROSION AND SEDIMENTATION. CLEARING OPERATIONS SHALL BE CONDUCTED SO AS TO EXPOSE THE SMALLEST PRACTICAL AREA OF SOIL TO EROSION FOR THE LEAST POSSIBLE TIME. TO CONTROL EROSION, IT IS ENCOURAGED THAT SHRUBS, GROUND COVER AND STUMPS BE MAINTAINED ON THE INDIVIDUAL LOTS, WHERE FEASIBLE. D. DIRECTIONAL FELLING. DIRECTIONAL FELLING OF TREES SHALL BE USED TO AVOID DAMAGE TO TREES DESIGNATED FOR RETENTION AND TO AVOID DAMAGE TO PRIVATE AND PUBLIC INFRASTRUCTURE. E. ADDITIONAL REQUIREMENTS.
