or hazards.If desired,DRG can provide additional levels of assessment or analysis for an additional fee that might help identify or further explore specic defects or tree conditions of interest. The specied period for the risk assessment is one year.The risk part of this inventory and evaluation is to keep in compliance with the most recent standards and practices in the arboricultural industry.It is important to note that DRG’s inspections are “rapid assessments”and are meant to show a need for further study;the assessments are not legally binding in any litigation. For the tree risk assessment,DRG’s urban foresters assign each tree one qualitative risk rating using the risk categorization matrices found in the ISA’s Best Management Practices -Tree Risk Assessment,Second Edition (E. Thomas Smiley,Nelda Matheny,and Sharon Lilly 2017).Various and multiple failure scenarios help determine a tree’s risk rating.The failure mode (i.e.,branch,whole tree,codominant stem)with the most signicant risk serves as the overall tree risk rating. Planting Sites When examining the state of Roseville’s urban forest,it is essential to assess more than just the trees themselves. Species diversity is integral to the sustainability of an urban forest.Understanding your current stocking level and potential ability is crucial to short-and long-term planning.When assessing planting sites,we follow the mantra “Right Tree in the Right Place for the Right Reason”.DRG will determine planting sites based on factors such as growing space,overhead utilities,and proximity to signs,lights,intersections,etc.Due to the nature of inventorying available planting sites,DRG recognizes the importance of understanding your goals and objectives for this tree inventory project.Based on your priorities,we recommend considering the following options: 1.100%Inventory.DRG will inventory all available planting sites during the tree inventory. 2.Partial Planting Site Inventory.DRG will prioritize and limit collection of the planting sites to keep the total number to approximately 25%of the total sites inventoried. 3.Five-Year Planting Strategy.Based on the current annual planting levels,DRG will locate ve years of potential planting sites.For example,if the City plants 100 trees annually,then DRG will locate approximately 500 available sites.These sites can be a combination of small,medium,or large based on planting goals. 4.Priority Areas (i.e.,Environmental Justice Areas).DRG will inventory available planting sites in predetermined areas during the tree inventory to facilitate improving canopy cover and diversity goals.
