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.

l MEASURES TO MAINTAIN PROPER OXYGEN AND WATER EXCHANGE WITH THE ROOT SYSTEM. IN ADDITION, THE FOLLOWING GUIDELINES
IARE TO PROTECT THE TREES TO BE PRESERVED.
I 1I A. WITH MAJOR GRADE CHANGES, A RETAINING WALL OR TREE WELL OF A DESIGN APPROVED BY THE GOVERNING AUTHORITY SHALL BE
