<br /> . ` <br /> 3 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 /> R-7.280-E.7.2.1 & 7.2.2 define "critical root zone" which is a term used <br /> in determining the required area around the tree to be protected from construction <br /> activities. The 3" caliper is the point at which the basis of determination changes from a <br /> protective azea of a three foot radius for smaller trees to a formula based measurement to <br /> provide larger protective areas for larger trees. <br /> Trees of many sizes may have need for protection on a development. 1-112" and <br /> 2" caliper trees in the planting program are minimums required and may be exceeded if <br /> the developer so elects. In addition, existing trees of varying sizes may be preserved. No <br /> correlation to the other tree caliper citations included in the planting specifications in these <br /> administrative rules was intended nor deemed to be necessary., nor is any revision to the <br /> rule necessary. <br /> Comment 11: The orange fencing required by R-7.280-E.7.5.2 is extremely ugly, + <br /> and the word "orange" should be removed. <br /> k~~s~itig: The purpose of the required fencing is to place a highly visible physical <br /> protective device in place to ensure no construction impacts to the. azea being protected. <br /> The standard orange protective fencing is specifically designed for this purpose and has <br /> been shown to be effective. However, R-7.280-E.7.5.2 also contains the statement "or <br /> approved .equivalent" which would provide an applicant a process to obtain approval for <br /> a substitution. A request for alternative fencing would be evaluated by the Urban Forester <br /> and if shown effective could be allowed in place of the specified "orange" fencing. For <br /> example, more physically substantial but less visible fencing material such as woven wire <br /> or chain link may, be approved,. as an alternate if site conditions warranted. <br /> Comment 12: The tree pruning standards in R-7.280-G.3.7 are vague, uncleaz, and <br /> do not make sense. <br /> Finding:I concur in part with this comment, and R-7.280-G.3.7 has been revised <br /> to clarify the intent. <br /> Comment 13: Although not addressing a specific rule, one party commented that <br /> it is hard to imagine that the City will be in a position to hire employees to carry out the <br /> Administrative Order - 4 <br /> <br />
