2 <br /> 1. Does the City Council want to remove a percentage of public ash trees each <br /> year for the next few years to spread out the removal and replacement costs? <br /> Staff has placed funding for tree removal/replacement in the capital <br /> improvement plan for 2013, and continues that into 2016. A spreadsheet listing <br /> existing ash trees within the maintained area of our parks and their removal <br /> costs is included below. <br /> Park Total # of trees: Estimated # of trees: Estimated Total <br /> ash 10" DBH Removal 11" DBH Removal Estimate <br /> trees or less Cost or more Cost for <br /> removal <br /> Arden Manor 2 2 $104 0 0 $104 <br /> Arden Oaks 2 2 $169 0 0 $169 <br /> Cummings 3 0 0 3 $520 $520 <br /> Floral 6 3 $182 3 $468 $650 <br /> Freeway 2 2 $208 0 0 $208 <br /> Hazelnut 3 1 $130 2 $429 $559 <br /> Ingerson 13 1 $130 12 $3,120 $3,250 <br /> Johanna Marsh 1 1 $130 0 0 $130 <br /> Lindey's 4 2 $208 2 $312 $520 <br /> Perry 21 12 $1,352 9 $1,599 $2,951 <br /> Royal Hills 12 1 $78 11 $2,054 $2,132 <br /> Sampson 1 0 0 1 $182 $182 <br /> Valentine 10 1 $117 19 , J $1,885 J $2,002. <br /> TOTALS 80 28 2,808 152 $10,569 1 $13,377 <br /> 2. If the City does want to begin removing ash trees before EAB is discovered in <br /> Arden Hills, does the Council want healthy trees removed or only ash trees in <br /> declining health? The draft management plan indicates that trees of declining <br /> health will not be saved. However, it does not mention that the City will <br /> remove healthy ash trees. <br /> 3. Does the City want all removed public ash trees replaced? The plan states that <br /> replacement of ash trees will be considered on a case to case basis. <br /> 4. With Oak Wilt and Dutch Elm Diseases, the City has historically left trees <br /> within the forested areas to die naturally. Removals have only been scheduled <br /> if the tree is located near a residential area. Staff is proposing to do the same <br /> with ash trees. Removing ash trees within the forested area would be a <br /> significant financial impact. Ramsey County and other surrounding Cities <br /> have adopted similar provisions. <br /> 5. Staff does not recommend that the City chemically treat any public trees at this <br /> time. Research has shown that the most effective treatment against Emerald <br /> Ash Borer is a root flare injected insecticide called Tree-Age (Emamectin <br /> Benzoate). This injection provides up to three growing seasons of protection <br /> before re-treatment is needed. The price of these injections vary but average <br /> i <br /> IlMetro-inet.uslardenhillslPR&PW1ParkslMemosICouncil Memos105212012 EAB plan.doc <br /> I' <br />
