To circle back to the original topic of this thread... I grew up under the base leg for runway 34. As a little kid, I used to love watching airplanes fly over my house at 500'. My parents still live in the same house.
The airport boundary used to be smaller, with Wolf and Hintz roads squared off. Both roads were moved and houses were torn down to expand the airport boundary (I think back in the 1990's). It was a major project.
In the early 1980's, I took piano lessons in a house on Wolf Rd, just south of Hintz near the departure end of 16. Back then, the old jets were so loud that it would rattle the windows of my piano teacher's house, and you couldn't hear the person next to you screaming when the jets would take off. We got used to it, jet taking off meant you'd just stop and wait for a minute.
Jets have come a long way since then, and so has the airport. Noise from jets is not an issue, even for people living close to the airport. With quiet jets now, residents near the airport are not impacted to the same degree as they were in the 1980's. My piano teacher's house was torn down to make way for the airport expansion, and it is now the approximate location of Atlantic Aviation. Many of the houses at the airport boundary across Wolf were tucked into a neigborhood 30 years ago before the road was relocted. They did good to expand the airport and create a buffer zone, but it did displace some long term residents with many houses torn down and neighborhoods changed.
The issue I see is that the airport is still seriously land locked and always has been. Any *meaningful* expansion of the runway has the potential to displace roads, homes, and businesses. Minor runway extensions aren't likely to have the intended result of attracting bigger faster jets. Waukegan to the north already has a 6000' runway, and DuPage has a 7500' runway. They can't add 1000' without tearing something up.
