I imagine most, if not all, residents moved in after the stadium was there.
Now I agree the traffic issue 100% needs looking at and sorting both currently and and for future expansions, as do things like pissing in gardens, but things like volume of people, noise, etc. were there decades upon decades ago. The house prices (both purchase and rental figures) represent the fact they are in vicinity of the stadium, and I imagine most moved around there in the knowledge that there are games played regularly during the season which attract many tens of thousands of people.
I couldn't argue against you there. We had 61,905 people in for a game in 1952. I appreciate times were different and much of the attendance was on a walk-up basis, but still. Back then and for decades afterwards, the ground was tightly hemmed in. If a resident fell out of bed they were virtually in the ground. These days there is acres of space around the ground in comparison. The landscaping around the Main Stand also helps serve as a buffer between homes and the ground now.
Noise- wise, you know the score if you choose, and choose definitely is the word here, to live to a major football ground. Don't get me wrong, I still sympathise, but no way in the world would I choose to live near a football ground even if it is the club I love.
Issues around the ground such as disorder must be much lower now than ever. Policing is better, stewarding is better and the levels of large scale disorder that happened in the 70s and 80s are now long gone.
Of course, I'd not put up with what the residents put up with, and with that in mind, I'd never move next to a football stadium, or any stadium for that matter. The ground has been there far longer than anyone who lives near it. Everything within the power of the club and the city council should be done to help both the residents and the club itself though.
My phone battery is about to die so my haste might mean I don't word this as sympathetically as I'd like, and I definitely do sympathise, but I'm also well aware of how long the ground has been there and that people usually make choices about where they live after weighing up the pros and cons beforehand.
I really don't know the answers to the current concerns residents have, but I hope a decent middle ground can be found. It's never going to a tranquil oasis though.
