Our Naperville, Illinois, 19 unit condo association, is surrounded by 31 ash trees. The emerald ash borer has been found in the next county. The question is to begin a planned elimination (cutting) of ash and replacement with a diverse species or treat with insecticide. These are large 27 year old trees. No EAB have been found. Several opinions are put forth: 1. Cut the ashes down as we can afford over 6 - 10 years with increased monthly dues to cover 2. Cut and use contingency fund until it runs out then have special assessment to replace. 3. Try insecticide route at ~$200 per year annually forever. Or each unit owner decides whether to treat and maintain treatment yearly 4. Wait and see how have other condo associations handled this problem?
