Z IN ADDITION TO THE ABOVE, THE DIRECTOR MAY REQUIRE 7HE FOLLOWING: A. IF EQUIPMENT IS AUTHORIZED TO OPERATE WITHIN THE PROTECTED ZONE, THE SOIL AND CRITICAL ROOT ZONE OF A TREE MUST BE CO VERED WI TH MULCH TO A DEP TH OF A T LEAST SIX INCHES OR W1 TH PL YWOOD, STEEL PLA TES OR SIMILAR MAZER/AL IN ORDER TO PROTECT ROOTS AND SOIL FROM DAMAGE CAUSED BY HEAVY EQUIPMENT. B. MINIMIZE ROOT DAMAGE BY HAND -EXCAVATING A TWO -FOOT -DEEP TRENCH, AT EDGE OF CRI RCAL ROOT ZONE, TO CLEANLY SEVER THE ROOTS OF TREES TO BE RETAINED. NEVER RIP OR SHRED ROOTS WITH HEAVY EQUIPMENT. C. CORRECTIVE PRUNING PERFORMED ON PROTECTED 7REES IN ORDER TO AVOID DAMAGE FROM MACHINERY OR BUILDING AC77V1 TY. D. MAINTENANCE OF TREES THROUGHOUT CONSTRUCTION PERIOD BY WATERING AND FERTILIZING. D. GRADE. 1. THE GRADE SHALL NOT BE ELEVATED OR REDUCED WITHIN THE CRITICAL ROOT ZONE OF TREES TO BE PRESERVED WITHOUT THE DIRECTORS AUTHORIZA7ON BASED ON RECOMMENDATIONS FROM A QUALIFIED PROFESSIONAL. THE DIRECTOR MAY ALLOW COVERAGE OF UP TO ONE-HALF OF THE AREA OF THE TREES CRITICAL ROOT ZONE WITH LIGHT SOILS (NO CLAY) TO THE MINIMUM DEPTH NECESSARY TO CARRY OUT GRADING OR LANDSCAPING PLANS, IF IT WILL NOT IMPERIL THE SURVIVAL OF 7HE TREE. AERATION DEVICES MAY BE REQUIRED TO ENSURE THE TREES SURVIVAL. 2. IF THE GRADE ADJACENT TO A PRESERVED TREE IS RAISED SUCH THAT IT COULD SLOUGH OR ERODE INTO THE TREES CRITICAL ROOT ZONE, IT SHALL BE PERMANENTLY STABILIZED TO PREVENT SOIL EROSION AND SUFFOCATION OF THE ROOTS J. 77-1E APPLICANT SHALL NOT INSTALL AN IMPERVIOUS SURFACE WITHIN THE CRITICAL ROOT ZONE OF ANY TREE TO BE RETAINED WITHOUT THE AUTHORIZATION OF THE DIRECTOR. THE DIRECTOR MAY REQUIRE SPECIFIC CONSTRUCTION METHODS AND/OR USE OF AERATION DEVICES TO ENSURE 77-1E TREES SURVIVAL AND TO MIN/M/ZE THE P07ENTIAL FOR ROOT -INDUCED DAMAGE TO THE IMPERVIOUS SURFACE. 4. TO THE GREATEST EX7ENT PRACTICAL, U77LITY TRENCHES SHALL BE LOCATED OUTSIDE OF THE CRITICAL ROOT ZONE OF TREES TO BE RETAINED. 77-1E DIRECTOR MAY REQUIRE THAT UTILITIES BE 7UNNELED UNDER THE ROOTS OF TREES TO BE RETAINED IF THE DIRECTOR DETERMINES THAT TRENCHING WOULD SIGNIFICANTLY REDUCE THE CHANCES OF 7HE TREES SURVI VAL. 5. TREES AND OTHER VEGETATION TO BE RETAINED SHALL BE PR07ECTED FROM EROSION AND SEDIMENTATION. CLEARING OPERA77ONS SHALL BE CONDUCTED SO AS TO EXPOSE THE SMALLEST PRACTICAL AREA OF SOIL TO EROSION FOR 7HE LEAST POSSIBLE TIME. TO CONTROL EROSION, IT IS ENCOURAGED THAT SHRUBS, GROUND COVER AND STUMPS BE MAINTAINED ON THE INDIVIDUAL LOTS, WHERE FEASIBLE. 6. THE DIRECTOR MAY APPROVE THE USE OF AL7ERNATIVE TREE PROTEC7ON TECHNIQUES IF THOSE TECHNIQUES PROVIDE AN EQUAL OR GREATER DEGREE OF PROTECTION THAN THE TECHNIQUES LISTED IN THIS SUBSECTION. E.
