INTEROFFICE MEMORANDUM TM Crn USA
TO: VILLAGE MANAGER MICHAEL E. JANONIS
FROM: FORESTRY /GROUNDS SUPERINTENDENT
DATE: MARCH 13, 2013
SUBJECT: BID RESULTS — EAB INSECTICIDE TREATMENT - $36,000
BACKGROUND
On February 25, 2013, 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. The specifications asked for prices for Tree -age treatments as our
Base Bid. However, just in case bid prices were unexpectedly high, we also asked for an Alternate
Bid for Xytect (an Imidacloprid product). Finally, we included a provision which will allow us to
extend the contract for a second year at the same bid prices, if both the contractor and Village agree.

Fourteen invitational bids were mailed and a notice was published in a local newspaper. Six bids
were received. The bid results were as follows:

BID DISCUSSION
In 2012, the trees being treated were broken into two groups. Group A consisted of trees 7" — 15"
in diameter and these were treated with Imidacloprid. Group B consisted of trees 16" in diameter
and larger and they were treated in 2012 for the first time with Tree -age. We propose in 2013 to

treat only the trees in Group A, with Tree -age. This product is believed by many to be the most
effective treatment for killing EAB larvae, and the unit price for treatment is reasonable. The bid
specifications identified 483 trees in Group A, totaling approximately 5,869 diameter inches. We
will soon re- measure all trees needing treatment. Based on last year's measurements, we expect
that all the trees in Group A will be able to be treated in 2013 with Tree -age by the low bidder,
TruGreen.
It should be noted that TruGreen has worked satisfactorily for us in the past. They have performed
multiple fertilization and pesticide application contracts, including our 2009, 2010, 2011 and 2012
EAB Insecticide Treatment contracts. (2011 and 2012 treatments were done jointly with Winkler's
Tree Service. TruGreen also treated the trees in Group B with Tree -age in 2012.)
BID RECOMMENDATION
There are funds available for this contract in the 2013 Budget. I recommend award of a possible
two -year contract for Tree -age treatment to the low bidder, TruGreen, in an amount not to exceed
$36,000.
If year one is successful, and a contract extension is agreed to by the Village and the contractor,
year two would be in an amount not to exceed whatever is appropriated for this purpose in the 2014
budget.
