Crispeno Arborist Report dated 9-2-15.pdf'1 AL "Ift AMP- app r y AL 11111111 ' 11415 NE 128d' St Suite 110 Kirkland WA 98034 * (425)820-3420 • FAX (425)820-3437 www.americanforestmanagement.com September 2, 2015 Mr. Carmen Crispeno 9812 2351h PL SW Edmonds, WA 98020-5634 Dear Mr. Crispeno: Today at your request, we re-evaluated the four significant Douglas -fir trees that were subject to our original report dated May 10th, 2012. The subject trees were encroached upon by sewer line improvements back in early 2012. Our assignment is to evaluate the condition and risk of the subject trees and report on our findings. The subject trees identified in the initial assessment were comprised of four mature Douglas -fir trees. These consisted of a grouping of three (#101, #102 and #103) at the top of the slope and an isolated tree (#104) at the toe of the slope near 235th PL SW. All suffered some root disturbance and loss related to the sewer line improvements. No change in condition was observed in the subject trees. The upper grouping remains sound and in good condition. Foliage color and density are normal. Tree tops are vigorous and have put on normal growth for age over the last few years. Tree #104 is also in a sound condition. Foliage color and density appears to have improved slightly since 2012. It has been well over three years since the construction impact. If the impacts were consequential to long-term health, we would expect to see some symptoms of stress or decline by now, particularly after this very dry summer. These symptoms might include thinning foliage (loss of needles), chlorotic (yellowing) foliage, dead tops, and/or reduction in growth over the last three years. The subject trees do not exhibit any signs of stress or decline. The subject trees remain a moderate risk, with the highest potential for failure and associated damage being related to future branch failures. Continued retention is feasible. Douglas -fir will commonly shed branches from time to time, usually during strong wind events. Lateral branches grow excessively long and tend to break off within a foot or two of the main trunk. Drooping branches are at the highest risk of failing. No recommendations are warranted at this time to reduce the future potential for branch failures. There is no warranty suggested for any of the trees subject to this report. Weather, latent tree conditions, and future man -caused activities could cause physiologic changes and deteriorating tree condition. Over time, deteriorating tree conditions may appear and there may be conditions, which are not now visible For a Forester Every Day is Earth Day September 2, 2015 Page 2 9812 235" PL SW Tree Assessment which, could cause tree failure. This report or the verbal comments made at the site in no way warrant the structural stability or long term condition of any tree, but represent my opinion based on the observations made. Nearly all trees in any condition standing within reach of improvements or human use areas represent hazards that could lead to damage or injury.
