San Luis Obispo, CA 0 401 8hauncnllarnnaUO6MaiLcom (805)440A90 Tree Protection and Preservation Plan For Shad and Michelle Perlich 2171 San Luis Drive San Luis Obispo, CA. 93401 September 23, 2013 Prepared by Shaun Callarman ISA Certified Arborist #WD256..A Lot Info: 00"82-007 DocuSign Envelope ID: BF9F16AB-96A1-4299-B7C7-ODA42ED3A235 Project Description: This project involves the construction of a single family home located at 2171 San Luis Drive, San Luis Obispo, CA. 93401 on lot 001.-082-001 Six existing Coast live Oaks, Quercus agrifoha, have been approved for removal at the above project site. The remaining native oak trees will be trimmed in accordance to ISA standw& The diameters of the Coast Live Oaks to be removed are (4) @) 18", (1) @ 13", and (1) 0 Was depicted on the grading plan. Specific Tree Mitigations and Protections Pertaining to the Project: The following mitigation measures must be fully understood and followed, by anyone working within the dripline (critical root zone) of any of the remaining trees. Any clarification will be provided by the arborist. It is the responsibility of the owner and/or general contractor to provide a copg of this tree protection plan to any and all subcontractors that work around or within the dripline of the remaining oak trees and confirm they are trained in maintaining fencing, protecting root zones and conforming to all tree protection measures. Aug future changes that would extend into the dripline of the saved trees will need to be reviewed by the project arborist before changes can proceed L Tree protection fencing shall be positioned according to the plans and constructed as described, below. The proposed fencing shall be placed at the edge of the dripline or line of encroachment for each tree. At a minimum, 4 foot orange safety fence shall be used and staked 8 feet on center with t� posts. A minimum of four zip ties on each stake should be used to properly secure the orange safety. fence. The fencing should be up prior to any construction or grading begins. The owner and/or general contractor shall be responsible for maintaining an erect fence throughout the construction period 2. All trenching within the dripline shall be hand dug. All major roots shall be avoided whenever,: , possible. All exposed roots larger than 1" in diameter shall be cut cleanly with sharp pruning tools and not left ripped or torn. A preconstruction meeting between the project arbornt and the grading contractor will take place before ang grading or trenching occurs near the remaining tree& 3. Grading within the dripline or safety fence should not take place unless specified on plans. Grading under 42" oak tree is approved bg tree committee for house footings only . Grading should not disrupt the normal drainage pattern around the trees Fills should not create a ponding condition and excavations should not leave the tree on a rapidly draining mound 4. Ang exposed roots shall be recovered the day thug were exposed. If they cannot, they must be covered with burlap or another suitable material and wetted down two times per day until reburied 5. Vehicles and all heavy equipment shall not be driven under the trees, as this will contribute to soil compaction. Also there is to be no parking of equipment or personal vehicles in these area& All areas inside orange safety fencing are off limits unless pre -approved by the project axborist. DocuSlgn Envelope ID: BF9F16AB-96A1-4299-B7C7-ODA42ED3A235 6. The existing ground surface within the critical root zone of all oak trees remaining shall not be cut, filled, or compacted unless specified on the grading plans and approved by the project arborist. The retaining wall around the 42" tree depicted on the plans will result in minimal compaction to the root system and is considered minor encroachment into the critical root zone. There will bea. 6" stone or concrete border around the tree to separate the dirt from the paving. Minor encroachment (5% or less) will occur but will not impact the overall health of the 42" diameter live oak that is to remain. Normally, only small surface roots (1" or less) are encountered at these distances from the main trunk All the utilities will be routed outside the critical root zone. A certified arborist will be on site during all construction activities within the drip line of the 42" live oak and a subsequent report stating that all construction activities were followed can be made available if requested as well as any significant findings or impacts which occurred during the project. 7. No liquid or solid construction waste shall be dumped on the ground within the critical root zone of any remaining tree on the project site. The storage of any material within the safety fencing is prohibited. & The project arborist will be on site during any digging or grading next to the 42" diameter coast live oak that is to remain. The closest place the footing of the house will be is 12 feet from the trunk which translates into minimal root pruning of 2" orless. This area will be hand dug and any roots. uncovered will be cut cleanly. As a result of the design of the house, the health of the lar6e oak and all of the remainin6 oaks in question should not be compromised if all tree protection measures are followed. The tree will be pruned to provide safety for the residents. 9. Prunin6 on the remainin6 trees will be performed by a certified arborist or the project arborist will r be on site. The removal of dead wood, thinning, lower limb removal and some crown reduction may be. required, but no pruning shall take more than 23% of the crown as per ISA standards. The zemaini na oak trees on the site will be pruned prior to any construction.
