ONCE ROOTS ARE EXPOSED BY THIS METHOD, THEY MAY BE EVALUATED BY AN ARBORIST. BY OBSERVING THE EXPOSED ROOTS, AN ACTION PLAN CAN BE PREPARED, WHICH MAY INVOLVE THE SEVERING OF SOME ROOTS AND WHILE MAINTAINING OTHERS. IF THE RECOMMENDED CONSTRUCTION GUIDELINES AND POST CONSTRUCTION MONITORING AND CARE ARE FOLLOWED, THE TREES SHOULD SUCCESSFULLY SURVIVE. ONLY TREES THAT HAVE A MODERATE TO ELEVATED LIKELIHOOD OF IMPACT ARE CONSIDERED IN THIS SECTION: TREES TO BE PRESERVED – ROOT LOSS MAY RESULT IN FLAGGING AND DESICCATED FOLIAGE. NO STRUCTURAL INSTABILITY ANTICIPATED. - ROOT PRUNING IS TO OCCUR NO CLOSER TO ANY TRUNK THAN THREE (3) TIMES THE DIAMETER, DUE TO POTENTIAL FOR SUBSTANTIAL ROOT LOSS AND INSTABILITY IF ROOTS ARE PRUNED ANY CLOSER. - CROWN CLEAN AND CLEARANCE PRUNE CONSTRUCTION-SIDE OF CANOPY PRIOR TO CONSTRUCTION ACTIVITIES; - PRUNE ROOTS BY HAND; - MULCH UNDER DRIPLINE TO A DEPTH OF SIX (6) INCHES MINIMUM AND MAINTAIN MULCH THROUGHOUT CONSTRUCTION ACTIVITIES; - SINGLE APPLICATION OF SLOW-RELEASE FERTILIZER AND PLANT GROWTH REGULATOR PRIOR TO CONSTRUCTION ACTIVITIES; - IRRIGATE MONTHLY DURING CONSTRUCTION ACTIVITIES WITH A FINAL IRRIGATION AT THE COMPLETION OF THE PROJECT; - MONITOR AND INSPECT MONTHLY DURING CONSTRUCTION ACTIVITIES WITH A FINAL ASSESSMENT AT THE COMPLETION OF THE PROJECT. THE FOLLOWING GUIDELINES MUST ALSO BE FOLLOWED: •TO HELP COMPENSATE FOR ANY POTENTIAL ROOT LOSS, IT WILL BE ESSENTIAL TO IRRIGATE ALL TREES DURING THE DRY MONTHS (ANY MONTH RECEIVING LESS THAN 1 INCH OF RAINFALL) FOR A MINIMUM OF ONE (1) YEAR. IRRIGATE A MINIMUM OF TEN (10) GALLONS FOR EACH INCH OF TRUNK DIAMETER EVERY TWO (2) WEEKS. A SOAKER HOSE OR A DRIP LINE IS PREFERRED FOR THIS PURPOSE. THIS IRRIGATION MUST BE APPLIED DURING THE TREES’ RECOVERY PERIOD, WHICH MAY BE LONGER THAN THE CONSTRUCTION PROCESS. •IF ANY LARGE ROOTS (2 INCHES IN DIAMETER OR LARGER) ARE SEVERED, THE STUB END(S) OF THE ROOT(S) MUST BE CLEANLY CUT USING A SHARP SAW AND SEALED USING A PLASTIC BAG TIED ON THE END. PLASTIC BAGS MUST BE REMOVED AT THE TIME OF BACKFILL. •MATERIALS MUST NOT BE STORED, STOCKPILED, DUMPED, OR BURIED INSIDE THE DRIPLINE OF TREES. •EXCAVATED SOIL MUST NOT BE PILED OR DUMPED, EVEN TEMPORARILY, INSIDE THE DRIPLINES OF PROTECTED TREES. •TREES TO BE PRESERVED MAY REQUIRE PRUNING TO CLEAR BRANCHES FROM PROPOSED STRUCTURES, SCAFFOLDING, OR NECESSARY EQUIPMENT AND SHOULD BE PERFORMED UNDER THE DIRECTION OF THE PROJECT ARBORIST. ANY PRUNING MUST BE PERFORMED OR SUPERVISED BY AN ARBORIST CERTIFIED BY THE ISA (INTERNATIONAL SOCIETY OF ARBORICULTURE) AND ACCORDING TO ISA, WESTERN CHAPTER STANDARDS, 1998. •THE IRRIGATION MUST NOT BE DESIGNED TO STRIKE THE TRUNKS OF TREES, BECAUSE OF POTENTIAL HIGH RISK OF DISEASE INFECTION.
