ENVIRONMENTAL BOARD <br />AGENDA ITEM 6B <br />STAFF ORIGINATOR: Andy Nelson <br />MEETING DATE: October 28, 2020 <br />REQUEST: Motion to approve or deny EAB injection program <br />TOPIC: EAB Injection Program <br />BACKGROUND: <br />The City response to EAB includes removals of boulevard ash trees, replacement of these <br />trees with a diverse mix of species, and insecticide injections that allow us to stagger removals <br />over time. There are currently 317 boulevard ash trees remaining. Our goal is to treat 100 trees <br />per year until there are less than 200 trees remaining, followed by treating half of the remaining <br />trees each year until we have removed and replaced them all. It will take the City about 10 years <br />to remove and replace these trees, barring acquisition of grant funding. <br />Projected Boulevard Ash Tree Treatments <br />and Removals <br />350 T— <br />Trees <br />remaining <br />Trees <br />treated <br />It took two workers about a month to treat 101 trees in the summer of 2020 and it cost $3,353.89 <br />for wages, chemicals, and injection equipment. <br />1 <br />
