Attachment N-8 <br />Page 4of5 <br />5. Three columnar maples on a east-west line, are against the curb of the McGrath's <br />parking lot: <br />There is a four foot tail cyclone mesh type fence running along the trees on this line. <br />A. Construction fencing should be placed to avoid compaction and other <br />damage to the trees over critical root zones as illustrated below, and left in place as <br />long as possible during construction, hopefully until end of summer or fall: <br />Attach temporary fencing to the cyclone fence at points x, E and W of each trunk. <br />x = distance East & West from trunk x <br />y = distance temp. fence runs south y <br />z = width of temp. fence in const.zone <br />North <br />x=10' <br />largest tree, most westerly: y = 20' <br />Z = 15' <br />x=9' <br />Middle tree: Y= 18' <br />z=12' <br />x=8' <br />Smallest tree, most easterly: y =16' <br />z= 11' <br />X <br />2. These three singular protection zones should be watered as described later for the <br />cedars along the east boundary of the project. The construction fencing for these <br />three trees will have to be moved back almost to the trees when excavation occurs <br />for the parking spaces. At that point, every precaution must be taken to avoid any <br />mechanical damage to the trunks, i.e. scratches, rips, and tears. <br />3. Special notes regarding largest of these three trees, the westerly tree with the <br />proposed walk way within it's drip line connecting with McGrath's parking lot: <br />a. Removal of top under the walkway within the peninsula should be limited to 6" <br />below grade. <br />b. Compaction within the peninsula area should be limited to the width of the <br />walk way. <br />c. No additional trenching for irrigation or utilities should occur within the peninsula <br />area, and a narrow un excavated area between the walk way and curb on west <br />side should be protected throughout the construction period with barrier fencing. <br />
