EXHIBIT “C” <br /> <br />TREE HAZARD EVALUATION PROGRAM <br /> <br />Program Objectives <br />The primary goal of the tree hazard evaluation program is to implement a <br />hazardous tree reduction program (HTRP) that will reasonably protect visitors <br />from unnecessary risks resulting from hazardous trees. An HTRP provides a <br />systematic method for mitigating tree hazards to avert damage to people or <br />property. The program will address the areas of visitor use, landscape <br />management, interpretation and transportation corridors (such as parking lot, <br />pathway, picnic grounds) which the public is openly invited or requested to use. <br />Definition of a Tree Hazard <br />A tree hazard refers to any potential tree failure due to a structural defect that <br />may result in property damage or personal injury. Every tree may eventually fail; <br />therefore, knowledge of each tree species, site characteristics, and local weather <br />conditions is essential when evaluating tree hazards. In recreation areas the <br />concern pertains to recreation facility visitors, employees, structures, vehicles or <br />other property. <br />Site Considerations <br />While tree hazard evaluation focuses on identifying tree defects and targets, the <br />influence of site factors on the development of tree hazards plays an important <br />role in determining potential threats. Slope, topography, aspect, irrigation <br />schedules, removal of adjacent trees, impacts from construction projects and <br />crown density are all examples of site considerations. Most failures will occur <br />during storm events with unusual winds and saturated soils. Knowledge of <br />regional and local climate as well as soils and topography is invaluable in <br />assessing failure potential. <br /> <br />Tree Hazard Evaluation Program Guidelines <br />Inspection <br />Periodically, any trees which stand within falling distance of public use areas and <br />which might pose a hazard to the public or significant property should be <br />systematically inspected for flaws. The form and frequency of routine inspection <br />or surveillance will depend on the type of visitor use areas (defined below). <br />Tree Care <br />Any tree denoted as hazardous should be promptly cared for, using the best <br />arboricultural techniques, to eliminate the hazardous status of the tree. If it <br />cannot be made safe, or if the effort to make it safe would be too costly in terms <br />of personnel time or dollars, then the tree may be removed. <br />557
