August 25, 1997 <br /> Scott Plamondon, Urban Forester <br /> City of Eugene <br /> 1820 Roosevelt Blvd. <br /> Eugene OR 97402 <br /> Subject: Hendricks Park Tree Removal <br /> The perspective of this letter is that of a concerned citizen oriented to maintaining an <br /> aesthetically pleasing Hendricks Park for all to enjoy safely. I have personally reviewed <br /> all of the trees 135rice over two days. This was done to confirm my observation of the <br /> condition of each of the 18 trees. I only thought this was appropriate to reduce the chance <br /> of error in my evaluation since the average age of the trees is in excess of 100 years. <br /> Background: Last year a large tree (stump and root structure observed and analyzed by <br /> the small group last Monday evening) fell in the winter. Fortunately the tree landed <br /> between two homes on the east -side of the park. The residents are of course concerned <br /> for the potential of damage and possible personal injury. The City of Eugene requested <br /> the Urban Forester to evaluate the condition of the remaining trees in the park. Initially <br /> 100 trees out of 233 were identified as potential hazards: subsequently that 100 was <br /> reduced to 18. <br /> The tree that fell last winter which can still be observed had an exceptionally well <br /> developed root structure. During this observation, the Urban Forester stated that this tree <br /> would have passed all tests that are used to evaluate hazardous trees. This is to state (as <br /> we all know in dealing with natural issues) Man's estimation is just that: an estimation. <br /> One of the most telling discussions last Monday related to the failures of all the trees lost <br /> in the park according to Park Gardner, Michael Roberts: with one exception all trees, <br /> both fir and oak fell due to root structure failure in supersaturated soil. This observation <br /> by Mr. Roberts is based upon his lengthy tenure in this park. By solving the surface <br /> water runoff and having a drip irrigation system installed for the summer season, we can <br /> attempt to reduce the number of failures. Water management is a major factor since no <br /> storm drains or collection gutters are located in either of the parking areas of both <br /> Summit Ave. and Birch Lane. Storm drains and gutters would remove the rain water and <br /> or excess irrigation. <br /> Before removing these 18 trees it seems to me that it is essential to evaluate all factors in <br /> minimizing the potential danger to neighbors and visitors to the park. We discussed the <br /> water conditions and feel that the City should solve the water problems. Surface runoff <br /> from the parking lots and the street was discussed. Surface runoff is substantial as is <br />
