curb feet. The rules establish location standards in R-7.280-C.1 for the placement of trees <br />to prevent conflicts with driveways and other structures. Depending on factors such as lot <br />size, driveway size, block size, and the location of public improvement, the location <br />standards may not allow an average of a 30 curb foot spacing to be achieved. In those <br />cases the maximum number of trees allowed by the location standards shall be the number <br />required. Credit for preserving existing trees and waiver of the requirement to plant trees <br />have been provided in the revision to R-7.280-C. l in response to comment 1. <br />Comment 6: The requirement of R-7.280-D.3.3 that trees be 100 % free from <br />insects, disease, etc. is not practical, and the section should be clarified to require the trees <br />be "reasonably free". <br />Findm~: I concur with this recommendation and Section R-7.280-D.3.3 has been <br />revised accordingly. <br />Comment 7: The requirement in R-7.280-D.3.4 that tree structural scaffold <br />branches be at least 6" apart where they attach to the main trunk should be revised to <br />require that the scaffold branches shall be well proportioned where they attach to the main <br />trunk. <br />Findin>?: I concur in part with this recommendation, and Section R-7.280-D.3.4 <br />has been revised to provide that the structural scaffold branches shall be well proportioned <br />where they attach to the main trunk with an average spacing of at least six inches. <br />Comment 8: The 2" caliper requirement for Arterial and Collector streets in R- <br />7.280-C.4.2 needs to be modified so that when the City takes possession of those trees, <br />the trees are 2" in caliper. <br />Finding: I concur with this recommendation, and Section R-7.280-D.4.2 has been <br />revised accordingly. <br />Comment 9: There is no need to waste City resources/funds on extending <br />administration time periods as required by R-7.280-E.1. If a tree has been replaced due <br />to vandalism or other conditions and that tree meets City criteria, i.e., 1.5 or 2" caliper <br />by the end of the original establishment period, then acceptance should be granted. <br />Finding: The purpose of a 3 year establishment period is to assure initial pruning <br />and 3 years of watering are provided to a young tree before it is expected to survive on its <br />own in Eugene's summer climate. Requiring the establishment period to be extended 3 <br />years from the date a replacement tree is planted achieves this purpose. Applying the <br />original tree's establishment period to a replacement tree would result in any subsequently <br />replaced tree receiving less than the 3 years of tree care necessary to assure survival, and <br />ultimately result in increased costs to the City to maintain replacement trees. Accordingly, <br />no revision is being made to this provision. <br />Comment 10: R-7.280-E.7.2.1 & 7.2.2 contain the only mention of 3" caliper. <br />This does not fit in with the other criteria contained in the rules. <br />Street Tree Plan Agreement -City Plants Alternate - 8 of 25 ~ ~ _ ®O ~ ~ 8 <br />
