DATE: APRIL 15, 2015
SUBJECT: BID RESULTS — EAB INSECTICIDE TREATMENT - $30,125
BACKGROUND
(P.
TREE CM USA
On April 13, 2015, sealed bids were opened for contractual treatment of selected parkway Ash trees
in attempt to prevent their infestation by the Emerald Ash Borer. As authorized by the Village
Board in 2009, we have been treating these trees annually with the hope that we will be able to
preserve a small population of high quality ash trees in our parkways. Previously, we have treated
all these trees with a product called Imidacloprid which must be applied each year. In 2012 we
started transitioning to a program in which all the trees will eventually be treated every two years
with a product called Tree -age. Our 2015-2016 specifications asked for pricing for treatments with
Tree -age only.
BID RESULTS
Fifteen invitational bids were mailed and a notice was published in a local newspaper. Eight bids
were received. The bid results were as follows:

BID DISCUSSION
In 2012 we put the treated ash trees into two groups to transition to the use of Tree -age, a two year
treatment. This product is believed by many to be the most effective treatment for killing EAB
larvae, and the unit price for treatment is reasonable. In 2015 we plan to treat Group A, consisting

of approximately 485 trees totaling 6500 diameter inches. In 2016 we plan to treat Group B,
consisting of approximately 340 trees totaling 6900 diameter inches. We will soon re -measure all
trees needing treatment. However, because the actual diameters of the trees might be slightly
different from our estimates due to growth, we have added a small contingency of $2,500.00 to each
year of the contract.
Note that this year's costs are less than our previous contract. For years 2013-2014 the cost per inch
was $4.87, in comparison to $4.25 for contract years 2015-2016.
It should be noted that Kinnucan has worked satisfactorily for us in the past. In 2007, Kinnucan
satisfactorily performed an EAB preventative treatment with a soil drench of Imidacloprid.
Additionally, they have performed our white light installation contracts from 2012 through 2014.
Finally, their submitted references were satisfactory.
BID RECOMMENDATION
There are funds available for this contract in the 2015 Budget. I recommend award of a two-year
contract for Tree -age treatment to the low bidder, Kinnucan Tree Experts, in an amount not to
exceed $30,125 for year one. Year two would be in an amount of $31,825.00 or whatever is
appropriated for this purpose in the 2016 budget.
I concur.
