Sam Oakley 231 Old Bernal Avenue Tree Inventory, Valuation, and Construction Guidelines 9/13/2024 6 PO BOX 2412 PISMO BEACH, CA 93448 (415) 407-6995 SAM@OAKLEYGROUP.ORG WWW.OAKLEYGROUP.ORG • To help compensate for any potential root loss, it will be essential to irrigate all trees during the dry months (any month receiving less than 1 inch of rainfall) for a minimum of one (1) year. Irrigate a minimum of ten (10) gallons for each inch of trunk diameter every two (2) weeks. A soaker hose or a drip line is preferred for this purpose. This irrigation must be applied during the trees’ recovery period, which may be longer than the construction process. • If any large roots (2 inches in diameter or larger) are severed, the stub end(s) of the root(s) must be cleanly cut using a sharp saw and sealed using a plastic bag tied on the end. Plastic bags must be removed at the time of backfill. • Materials must not be stored, stockpiled, dumped, or buried inside the dripline of trees. • Excavated soil must not be piled or dumped, even temporarily, inside the driplines of protected trees. • Trees to be preserved may require pruning to clear branches from proposed structures, scaffolding, or necessary equipment and should be performed under the direction of the Project Arborist. Any pruning must be performed or supervised by an arborist certified by the ISA (International Society of Arboriculture) and according to ISA, Western Chapter Standards, 1998. • The irrigation must not be designed to strike the trunks of trees, because of potential high risk of disease infection. General Construction Guidelines Any tree located within the footprint of the proposed structures will be removed prior to construction. If construction will impact any other individuals located on this site, the contractor shall abide by the general construction recommendations listed in the following section of this report. The tree protection measures for establishing a Tree Protection Zone (TPZ) are as follows. All work within the dripline or TPZ (whichever is greater) is to be done by hand in the presence of the Project Arborist or designee. The TPZ is established as follows: • Tree Protection Fencing: The fence shall enclose the entire area under the canopy dripline or TPZ (whichever is greater) of the tree(s) to be protected throughout the life of the construction project. In some parking areas, if fencing is located on paving or concrete that will not be demolished, then the posts may be supported by an appropriate grade level concrete base, if approved.
