A MINIMUM COVER OF 42" UNLESS
OTHERWISE NOTED OR EXPLICITLY
APPROVED BY THE CITY ENGINEER.
8. THE LOCATION OF UNDERGROUND
FACILITIES INDICATED ON THE PLANS IS
TAKEN FROM PUBLIC RECORDS. IT IS THE
CONTRACTOR'S RESPONSIBILITY TO
CONFIRM THEIR EXACT LOCATION AND TO
DETERMINE WHETHER ANY ADDITIONAL
FACILITIES OTHER THAN THOSE SHOWN ON
THE PLANS MAY BE PRESENT, DETERMINE
IF ANY CONFLICTS EXIST AND NOTIFY THE
ENGINEER OF ANY SUCH CONFLICTS PRIOR
TO BEGINNING CONSTRUCTION. THE

1. GENERAL CONSTRUCTION NOTES: REFER TO SHEET C-X.X "GENERAL CONSTRUCTION NOTES, LEGEND AND ABBREVIATIONS" FOR THE
GENERAL CONSTRUCTION NOTES FOR THE PROJECT.
2. TREE PROTECTION IDENTIFICATION: PRIOR TO GRADING, BRUSH REMOVAL, OR SITE CONSTRUCTION, THE CONTRACTOR SHALL MEET
WITH THE DEVELOPER AND/OR ENGINEER AT THE SITE TO ASCERTAIN THE AREAS OF THE EXISTING TREES TO BE PROTECTED AND
PRESERVED. THE CONTRACTOR SHALL THEN CLEARLY TAG OR MARK ALL TREES TO BE PROTECTED AND PRESERVED. NO TREES SHALL
BE CUT AND/OR REMOVED FROM THE PROJECT SITE UNTIL SPECIFICALLY AUTHORIZED IN WRITING BY THE GOVERNING AUTHORITY
AND/OR DEVELOPER.
3. TREE PROTECTION FENCE: THE CONTRACTOR SHALL ERECT A FENCE (PER DETAILS) AROUND EACH TREE TO PREVENT THE PLACEMENT
OF DEBRIS OR FILL WITHIN THE DRIP LINE OF THE TREE. THE TREE PROTECTION FENCE LOCATION SHOWN ON THE PLAN IS SCHEMATIC IN
NATURE.
4. TREE CANOPY RESTRICTIONS: DURING CONSTRUCTION, THE CONTRACTOR SHALL PROHIBIT CLEANING, PARKING OR STORAGE OF
EQUIPMENT OR MATERIALS UNDER THE CANOPY OF ANY TREE OR GROUP OF TREES BEING PRESERVED. THE CONTRACTOR SHALL NOT
ALLOW THE DISPOSAL OF ANY WASTE MATERIAL SUCH AS, BUT NOT LIMITED TO, PAINT, OIL SOLVENTS, ASPHALT, CONCRETE, MORTAR,
ETC., IN THE CANOPY AREA.
5. TREE ATTACHMENT RESTRICTIONS: NO ATTACHMENTS OR WIRES OF ANY KIND, OTHER THAN THOSE OF A PROTECTIVE NATURE, SHALL
BE ATTACHED TO ANY TREE.
6. FILL RESTRICTIONS: NO FILL OR EXCAVATION MAY OCCUR WITHIN THE DRIP LINE OF A TREE TO BE PRESERVED WITHOUT AN APPROVED
PLAN FOR USE OF TREE WELLS OR RETAINING WELLS. CHANGES OF GRADE SIX (6) INCHES OR GREATER SHALL REQUIRE ADDITIONAL
MEASURES TO MAINTAIN PROPER OXYGEN AND WATER EXCHANGE WITH THE ROOT SYSTEM. IN ADDITION, THE FOLLOWING GUIDELINES
ARE TO PROTECT THE TREES TO BE PRESERVED.
A. WITH MAJOR GRADE CHANGES, A RETAINING WALL OR TREE WELL OF A DESIGN APPROVED BY THE GOVERNING AUTHORITY SHALL BE
CONSTRUCTED AROUND THE TREE NO CLOSER THAN HALF THE DISTANCE BETWEEN THE TRUNK AND THE DRIP LINE. THE RETAINING
WALL SHOULD BE CONSTRUCTED SO AS TO MAINTAIN THE EXISTING GRADES AROUND THE TREE OR GROUP OF TREES.
B. AT NO TIME SHALL A WALL, PAVEMENT OR POROUS PAVEMENT BE PLACED LESS THAN FIVE (5) FEET OR ONE (1) FOOT FOR EVERY
TWO (2) INCHES IN CALIPER, WHICHEVER IS GREATER, TO THE TRUNK OF THE TREE.
C. ROOT PRUNING WILL BE REQUIRED WHEN THE CRITICAL ROOT ZONE IS TO BE DISTURBED. THIS IS IN AREAS WHERE PAVING OR THE
BUILDING PAD EXTENDS TO OR BENEATH THE DRIP LINE OF THE TREE.
