ARDEN HILLS CITY COUNCIL WORK SESSION—FEBRUARY 18, 2014 10 <br /> Parks and Recreation Manager Olson reported that the treatments are up to 90% effective if <br /> completed every two years on an EAB Ash tree. She further discussed the Department of <br /> Agriculture's success rate for the treatment product called Tree-Age. <br /> Councilmember Werner asked how much residents in Arden Hills would be charged to treat <br /> their Ash trees. <br /> Parks and Recreation Manager Olson explained that trees up to 24" would be $7.00 per caliper <br /> inch and trees over 24"would cost $9.00 per caliper inch. <br /> Mayor Grant supported treating the Ash trees. He did not want to see the City lose a large <br /> number of trees. <br /> Councilmember Holmes inquired how long the treatments would be needed. <br /> Parks and Recreation Manager Olson stated that the treatments would be needed every two <br /> years, until the disease was under control, or has moved on. <br /> Councilmember McClung was uncertain how he feels about this issue. He does not want to see <br /> the City lose a large number of trees as this would impact the City's parks. He suggested that the <br /> significant trees within the City's parks be treated. He recommended that the City investigate <br /> supplemental tree plantings to assist in diversifying the conifers in the City's parks. <br /> Councilmember Holmes supported staff s plan to treat the EAB trees. She inquired if the City <br /> has funds to cover the expense for the treatment and removal of damaged trees. <br /> Parks and Recreation Manager Olson stated that funds have been set aside in future years for <br /> tree removal. <br /> Mayor Grant suggested that the City treat the Ash trees this year and that in 2015 the Council <br /> reconsider the removal of damaged or declining trees. <br /> Councilmember Holden recommended that the untreated trees be removed as this would reduce <br /> the threat of EAB spreading further in the community. <br /> Parks and Recreation Manager Olson stated that the City could easily remove the smaller 4" <br /> trees. <br /> Councilmember Holmes suggested that all trees 10" or smaller be removed. <br /> Public Works Director Maurer indicated that the trees could be treated in late May or early June <br /> and after that time, staff could report back to the Council with more detailed maps of the <br /> remaining Ash trees. This would allow for further discussion regarding which trees should and <br /> should not be removed. <br /> Mayor Grant questioned if this information should be reviewed by the PTRC. <br />
