ORANGE PRO7ECTI VE BARRIER FENCING SHALL BE PLACED AT THE DRIP LINE OF TREES TO REMAIN AND AROUND AREAS PROPOSED FOR LOW IMPACT DEVELOPMENT TECHNIQUES, SUCH AS RAIN GARDENS, INF/L 7RA T10N SYSTEMS, ETC., TO PROTECT THE AREA FROM COMPAC770N. TREE PROTECT/ON NOTES 1. ANY WORK INSIDE THE DRIP LINES OF EXISTING TREES MUST TAKE PLACE IN ACCORDANCE WITH ECDC 23.10.070. 2. TREE PROTECTION MEASURES DURING DEVELOPMENT - A. PRECONSTRUCT70N MEETING REQUIRED. PRIOR TO THE COMMENCEMENT OF ANY PERMITTED CLEARING AND GRADING ACTIVITY, A PRECONSTRUC77ON MEETING SHALL BE HELD ON SITE WITH THE PERMI TTEE AND APPROPRIATE CITY STAFF. THE PROJECT SITE SHALL BE MARKED IN THE FIELD AS FOLLOWS.- 1. THE EXTENT OF CLEARING AND GRADING TO OCCUR; 2. DELINEATION AND PROTECTION OF ANY CRITICAL AREAS AND CRITICAL AREA BUFFERS WIN CLEARING LIMIT FENCING; J. FLAGGING OF TREES TO BE REMOVED AND TAGS ON TREES TO BE RETAINED, AND 4. PROPERTY LINES B. PLACING MATERIALS NEAR TREES. 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 STOCKPILING ANY MATERIALS, OR DUMPING CONCRETE WASHOUT OR OTHER CHEMICALS. DURING CONSTRUCTION, NO PERSON SHALL ATTACH ANY OBJECT TO ANY TREE DESIGNATED FOR PROTEC770N. C. PROTECTIVE BARRIER. BEFORE DEVELOPMENT, LAND CLEARING, GRADING, FILLING OR ANY LAND ALTERATION, THE APPLICANT SHALL: 1. ERECT AND MAINTAIN READILY VISIBLE TEMPORARY PROTECTIVE TREE FENCING ALONG 7HE LIMITS OF DISTURBANCE WHICH COMPLETELY SURROUNDS 7HE PROTECTED AREA OF ALL RETAINED TREES, GROUPS OF TREES, VEGETATION AND NA77VE SOIL. TREE PROTECTIVE FENCING SHALL BE A MINIMUM HEIGHT OF 77-IREE FEET, VISIBLE AND OF DURABLE CONSTRUCTION,• ORANGE POLYETHYLENE LAMINAR FENCING IS ACCEPTABLE. 2. INSTALL HIGHLY VISIBLE SIGNS SPACED NO FUR7HER THAN 15 FEET APART ALONG THE ENTIRETY OF 77-1E PR07EC77VE TREE FENCING. SAID SIGN MUST BE APPROVED BY THE DIRECTOR AND SHALL STATE AT A MINIMUM, "TREE AND SOIL PROTECTION AREA, ENTRANCE PROHIBITED, " AND PROVIDE 7HE CITY PHONE NUMBER FOR CODE ENFORCEMENT TO REPORT VIOLA TIONS J. PROHIBIT EXCAVATION OR COMPAC77ON OF SOIL OR OTHER P07ENTIALLY DAMAGING ACTIVITIES WITHIN THE BARRIERS,• PROVIDED, THAT 7HE DIRECTOR MAY ALLOW SUCH ACTVITIES APPROVED BY A QUALIFIED PROFESSIONAL AND UNDER THE SUPERVISION OF A QUALIFIED PROFESSIONAL RETAINED AND PAID FOR BY THE APPLICANT. 4. MAINTAIN THE PR07ECTIVE BARRIERS IN PLACE FOR THE DURATION OF 77IE PROJECT UN77L THE DIRECTOR AUTHORIZES THEIR REMOVAL. 5. ENSURE THAT ANY APPROVED LANDSCAPING DONE IN THE PROTECTED ZONE SUBSEQUENT TO THE REMOVAL OF THE BARRIERS SHALL BE ACCOMPLISHED WITH MACHINERY FROM OUTSIDE THE PROTECTED ZONE OR BY HAND. 6. LIMIT THE TIME PERIOD 7HAT THE CRITICAL ROOT ZONE IS COVERED BY MULCH, PLYWOOD, STEEL PLATES OR SIMILAR MATERIALS, OR BY LIGHT SOILS, TO PROTECT THE TREES CR/T7CAL ROOT ZONE. Z IN ADDIT70N TO THE ABOVE, THE DIRECTOR MAY REQUIRE THE FOLLOWING: A. IF EQUIPMENT IS AU7HORIZED TO OPERATE W17HIN THE PRO7EC7E0 ZONE, 7HE SOIL AND CRITICAL ROOT ZONE OF A TREE MUST BE COVERED W IN MULCH TO A DEPTH OF AT LEAST SIX INCHES OR W/TH PLYWOOD, S7EEL PLATES OR SIMILAR MATERIAL 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 CRITICAL ROOT ZONE, TO CLEANLY SEVER 77-1E ROOTS OF TREES TO BE RETAINED. NEVER RIP OR SHRED ROOTS WITH HEAVY EQUIPMENT. C. CORREC77VE PRUNING PERFORMED ON PROTECTED TREES IN ORDER TO AVOID DAMAGE FROM MACHINERY OR BUILDING ACTIVI TY. D. MAINTENANCE OF TREES THROUGHOUT CONS7RUCTION 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 77IE DIRECTORS AU77-IORIZATION BASED ON RECOMMENDA77ONS FROM A QUALIFIED PROFESSIONAL. THE DIRECTOR MAY ALLOW COVERAGE OF UP TO ONE-HALF OF THE AREA OF 774E TREES CRI77CAL 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 THE 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 SUFFOCAT70N OF THE ROOTS J. 77-IE APPLICANT SHALL NOT INSTALL AN IMPERVIOUS SURFACE WITHIN THE CRI77CAL 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 THE TREES SURVIVAL AND TO MINIMIZE THE POTENTIAL FOR ROOT -INDUCED DAMAGE TO THE IMPERVIOUS SURFACE. 4. TO THE GREATEST EXTENT PRACTICAL, UTILITY TRENCHES SHALL BE LOCATED OUTSIDE OF THE CRI77CAL ROOT ZONE OF TREES TO BE RETAINED. THE DIRECTOR MAY REQUIRE THAT UTIL/T7ES BE TUNNELED UNDER THE ROOTS OF TREES TO BE RETAINED IF THE DIRECTOR DETERMINES THAT TRENCHING WOULD SIGNIFICANTLY REDUCE 77IE CHANCES OF THE TREES SURW VAL. 5. TREES AND OTHER VEGETATON TO BE RETAINED SHALL BE PROTECTED FROM EROSION AND SEDIMENTATION. CLEARING OPERAT70NS SHALL BE CONDUCTED SO AS TO EXPOSE THE SMALLEST PRACTICAL AREA OF SOIL TO EROSION FOR THE LEAST POSSIBLE TIME. TO CON7ROL 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 ALTERNATIVE TREE PROTECTION TECHNIQUES IF 77-IOSE TECHNIQUES PROVIDE AN EQUAL OR GREATER DEGREE OF PROTECTION THAN THE TECHNIQUES LISTED IN THIS SUBSECTION. E. DIRECTIONAL FELLING. DIREC7ONAL FELLING OF TREES SHALL BE USED TO AVOID DAMAGE TO TREES DESIGNATED FOR RETENTION.
