NOTES:
1. MINIMUM FIVE (5) FOOT HIGH TEMPORARY CHAINLINK FENCE
SHALL BE PLACED AT THE CRITICAL ROOT ZONE OR DESIGNATED
LIMIT OF DISTURBANCE OF THE TREE TO BE SAVED. FENCE SHALL
COMPLETELY ENCIRCLE TREE(S). INSTALL FENCE POSTS USING
PIER BLOCK ONLY. AVOID POST OR STAKES INTO MAJOR ROOTS.
MODIFICATIONS TO FENCING MATERIAL AND LOCATION MUST BE
APPROVED BY PLANNING OFFICIAL.
2. TREATMENT OF EXPOSED ROOTS DURING CONSTRUCTION: FOR
ROOTS OVER ONE (1) INCH DIAMETER DAMAGED DURING
CONSTRUCTION, MAKE A CLEAN STRAIGHT CUT TO REMOVE THE
DAMAGED PORTION OF ROOT. ALL EXPOSED ROOTS SHALL BE
TEMPORARILY COVERED WITH DAMP BURLAP TO PREVENT
DRYING, AND COVERED WITH SOIL AS SOON AS POSSIBLE.
3. NO STOCKPILING OF MATERIALS, VEHICULAR TRAFFIC, OR
STORAGE OF EQUIPMENT OR MACHINERY SHALL BE ALLOWED
WITHIN THE LIMIT OF THE FENCING. FENCING SHALL NOT BE
MOVED OR REMOVED UNLESS APPROVED BY THE CITY PLANNING
OFFICIAL. WORK WITHIN THE PROTECTION FENCE SHALL BE DONE
MANUALLY UNDER THE SUPERVISION OF AN ON-SITE ARBORIST
AND WITH PRIOR APPROVAL BY THE CITY PLANNING OFFICIAL.8/22/2022 1:44 PMJ:\2021\21159\LANDSCAPE\PRELIMINARY\SHEETS\21159 P11.DWGDESIGN12100 NE 195th St, Suite 300 Bothell, Washington 98011 425.885.7877CIVIL ENGINEERINGLANDSCAPE ARCHITECTUREPLANNINGSURVEYING21159SUMMIT AT STEEL LAKECOPPER RIDGE, LLCSW1/4 OF THE SE1/4, SEC. 05, TWP. 21 N., RGE. 4 E., W.M.
