All you need to do is spend the day at the Sky Ranch Park and realize how little a factor the airport is. I’m speaking from someone who lives up here, and I’ve talked to neighbors who never complain of the airport. So, you need to come up here and hang out for the day. Also, there is a lookout point right across from the Eaglepointe model homes. Just drive up to Sky Ranch and park here. Get out of the car, and you can get a feel for what it would be like.
The main road up the hill is very straight except at the bottom where it connects to Graves and at the top where it goes past the NorthStar condos. Many trucks and cars drive up and down this road daily from morning to night, and as far as I know, there hasn’t been a single accident, other than cars getting jolted by the heavy duty speed bumps.
Also, most approaches for the airport come directly from East to West on the South side of the mountain, or they come going North than turn West to line up with the runway. Sometimes they do come over the mountain going North to South, then turning West to line up with the runway. There is less of this approach from what I see, and it depends on the weather conditions.
Here is someone flying over Rattlesnake mountain (Sky Ranch) getting ready for an approach. You can see Sky Ranch in the early days of development. In this one, he is coming in from the West with Sky Ranch coming in on the left side of the screen, then he loops around Sky Ranch to take the East to West approach:
