h) age and condition of the stand — trees have a poorer response to stress factors with age <br /> �rrr i) interruption of the wet and dry cycle caused by irrigation, which creates more favorable <br /> conditions for disease and insect attack <br /> 2. Major adjustments in park maintenance and irrigation practices have been <br /> made over the last several years to ameliorate the conditions listed above. These <br /> include: <br /> a. relocating hundreds of ornamentals away from the root zone of trees <br /> b. retrofitting and upgrading irrigation systems to redirect water away from trees stems <br /> and root zones <br /> c. applying water more efficiently with multi - cycling, deeper and less frequent <br /> watering, and extensive monitoring to avoid saturation and runoff <br /> d. some hand watering of plants in combination lawn and shrub zones <br /> e. removing some sprinklers, changing nozzles and spray patterns <br /> f. reducing impact of maintenance vehicles <br /> g. more sensitivity to construction impacts, e.g. removal of the destroyed picnic shelter <br /> with special prescriptions <br /> h. recent stormwater drainage improvements, which included roadside curbing and run - <br /> off tied to storm drains <br /> i. in general, there has been a moratorium placed on tree removal until the Hendricks <br /> Park Forest Management Plan has been prepared. <br /> Finding #1: <br /> Irrigation activities represent a major cultural factor that can be controlled in <br /> Hendricks Park. Because tree health and safety are of the highest priority, and <br /> there is evidence that irrigation is likely a contributing factor to tree decline, a <br /> "least risk" approach should be taken. <br /> Finding #2: <br /> Soil conditions and root health are an important part of the "hazard triangle" <br /> analysis of windthrow safety. Windthrow evidence has shown that root health <br /> and development have been impacted by poor drainage and excess moisture at <br /> this site. <br /> (kw <br />
