I am an alumni of Northern Illinois University.
Three of my many classes were held in Cole Hall.
My sympathies and prayers go out to those families and friends who had loved ones there that sad day.

The Village Manager and staff have decided the “Heritage Tree Ordinance” (HTO) is not going to happen right now. Unless someone on council takes exception to it, it will be left on the back burner. That is too bad. We need a responsible, moderate, heritage tree ordinance now, so we can measure and adjust it if needed in the future. Read the rest of this entry »

Trees take in carbon dioxide and water, both things we have too much of here in DG, fix the carbon to the water to make…more tree (cellulose), and exhale the remaining oxygen. Most trees have root structures that are wide and shallow to gather nutrients and water, and maybe some soil based carbon. A fully grown tree can absorb up to 600 gallons of water in a 24 hour period. Once the soil surrounding a root structure has been flooded or saturated, that ability is greatly diminished; that is why many trees die if their surroundings get too wet.
Some trees, like swamp oaks, red maples, river birches, keep soaking up water whether or not the ground is saturated. They adapted to the marshy lowland prairies where we now live. Willows are the midwest champs for soaking up water, but they grow fast and are weak, and tend to fall over in high winds.
Shade trees have expansive canopies for several reasons; to collect gaseous carbon dioxide (greenhouse gas), to collect sunlight as the trees’ power source for the chemical reactions, and to transpire out the oxygen and excess water vapor. Read the rest of this entry »
Note: This started as an offshoot of discussions and postings here and at DGreport.com. I specifically would like to thank everyone who participated with questions, whether I used them or not.
We all can have different opinions, but in the end we all have something akin to affection for the village we live in: that is why we care, and that is why we share common ground.
Mayor Sandack, thank you for participating in this on-line interview, and let’s jump right in. Read the rest of this entry »
In 2007, I was point in a skirmish with our local government over a lack of transparency, of deliberate opaqueness. This was the C&D issue; you would have to be deaf dumb and blind not to know about it. I gave up on the demand for transparency when the outcome was favorable. Read the rest of this entry »
I have to go back Sunday and see this one finished. The artists starts out with cubes of ice and ends up with perfect spheres to be used as balls for his sculpture.
Interim Director of Public Works Robin Weaver broke the sobering news to council tonight: the Emerald Ash Borer (EAB) is on the way, it’s closer than anyone thinks, and nothing anyone has done stops the 100% lethality of this pest. Evanston is getting hammered right now; hundreds of trees need removal, and their Public Works crews are swamped.
It’s all very sad. Ash trees had their foibles, but some, especially purple Ash, really are beautiful shade trees. Hardy, tolerant, robust, and completely vulnerable to a small bug from China. Probably the best way to know the EAB has arrived will be the tiny sideways ‘D’ holes in the tree, and the woodpeckers pecking away eating everyone they can find. Sorry, the woodpeckers don’t stop them either.
Public Works will be taking out 400-450 trees this year, trying to get ahead of the problem like everyone else did not. Replacing all those trees is going to cost money, and it is my intention to see what we residents might do to help lower the cost to the village. I’ll report in on this if/as things happen.
