My re- view of the 18 hazard trees and the overall stand of timber as a vege- tative cover type located in Hendrick's Park raised several issues that appear to intimately connected with the project of the hazard tree re- moval. The issues deal with the collection of factual information and the resolution of the problem based on those facts that were initially collected. Issue one.. There was no substantive factual information offered by the Urban For- ester or his supervisor at the meeting held on August 18, 1997 at the Hendrick's Park Shelter. What information that was offered was interp- retive at best. Issue two. No definitive data was offered as to the amount and location of the fun- gus infection and the degree of incipient or advanced stage of the in- fection. . .. Issue three. ". No data was offered 'as to occurrence of other fungi (which would be, in their - advanced stage more destructive to the physical structure com ponenyof the tree, than 'the observed fungus). Issue four. Nothing was offered about the soil series found on the immediate area, ho information about windfirmnessof the soil series in relation to sup- porting trees involving high velocity winds. No data was offered on av- erage soil depth, average rooting depth,.. and water holding capacity of the soil series found on the area. All of these statistics affect tree growth and the spread of disease and fungi. Issue five. No data was offered about the interrelationship of tree stability, soil series, toporaphy. No. facts . were offered about the above relationship and the:effect `on it by wind velocity, turbulance and precipitation.. Issue six. , No data was offered on the condition of the stands of trees in the parr as an overall observation. No assessment of tree vigor, susceptability - to disease and fungus infection.. A general. of city liability and private citzen liability 'in ``re lation to damage caused by natural forces (trees falling on houses) was" made by a city employee. That comment was in direct cntradiction to known legal precedent.. The lack of data on which I personally would »awe relied on to make a decision to harvest or not individual tree caused me to inquire of
