Ash Trees Throughout Our Subdivision – and Emerald Ash Borers (EAB) That Are Killing Them
The original developers of this subdivision planted and left many existing Ash Trees, along with various types of Maples, throughout the area. This was no problem back in 2000, but since 2008, the EAB has moved into Wisconsin and is quickly killing these Ash Trees. In fact, Wisconsin is now a “quarantine state” such that cut ash tree wood cannot be cut and be moved elsewhere to be used as firewood. In 2016, your HOA determined that many of the Ash Trees near the Silver Spring entrance were heavily invested and/or already dead, and so had them removed and/or replaced (with a different type of tree). Some additional trees in that area will probably receive the same action this year. These HOA common-areas trees will be acted upon using HOA funds. The Condo Association will, of course, evaluate and take appropriate action on their ash trees as they see fit, while individual HOA house owner members are responsible for their own trees.
In early 2017, one of our Members using his own property containing many Ash Trees and located only two blocks from this entrance, had several tree services examine them as a test. They all found that these trees had either no or light infestation and could probably still be saved. Given that while some trees on a property don’t have to be replaced when removed, “street trees” do have to be replaced. The choice is either “wait until each tree dies (expected in the next 1-3 years), then spend $500-$800 EACH to replace with a new smaller tree – or treat existing mature tree(s) that can still be saved, at an annual cost of approx. $30-35/year/tree, depending upon tree size/trunk diameter. The reason for investigation, decision, and action NOW is because the most effective treatment time is mid-Spring (May-June).
Insecticide treatments available are either a soil injection or a tree-trunk injection. Over the last 5-7 years of usage, the soil injection method has been found to be about 60-80% effective and the trunk injection treatments to be about 95-98% effective. While some of the chemical soil methods can be done by homeowners, most of both types of treatments are usually best done by commercial trees services. While this approach costs more, the professional knowledge, safety concerns involved, and effectiveness appear to be worth it. The most common chemical trunk injection used, of Emamectin Benzoate, is applied every two years.

Subdivision Roads Surfaces (Good and Bad Conditions)
About 3 - 4 years ago, M. Falls did a resurfacing of our subdivision roads (Autumn View, Creekwood Crossing, Hidden Lane, Ravenwood, Ridgewood, and Walnut Way, including Courts off it). Many of us noted that, while the Walnut Way surface appeared to be pretty good afterwards and remains so to this day, the surface of the other roads quickly acquired long cracks and many large worn surface areas. The “common thought” was that perhaps two different contractors were used by M. Falls, one good, one not good.
A recent discussion with the Director of Engineering for M. Falls helped clarify this situation. Unfortunately, the problem was not with the resurfacing job done, but rather with the original roadwork, and methods used on each of these, back in the 1999-2004 timeframe. Apparently, most of our residential roads were constructed using a (now known to be poorer-method) vs. Walnut Way which was constructed in 2003-2004 using a totally different method. Not being a street-engineer myself, I am not going to try to understand, or explain, the differences. However, the Director of Engineering indicated that this is why they have (now) learned that standard “every 8 or 10-year resurfacing methods” are ineffective on M. Falls’s older roads, and that his Dept. is slowly working through a list of those that need a more substantial “tear off and rebuild (in my words)” action to improve.
While none of this information immediately “fixes” our subdivision’s road surfaces, at least it hopefully better explains why so many of them looked “poor condition” right after the recent resurfacing work done.
