Actually, there won't be any particular change to noise impact for residents at all. Overnight, aircraft have always landed from over water to RWY19L and departed over water from RWY01R, when weather conditions allowed (i.e. tailwind below 5kts) by using 'Reciprocal runway operations'. The only change is that 'SODPROPs' will mean aircraft land on RWY19R and depart from RWY01R. So, they will still be arriving/departing over water, same as they are now and have been for years. They'll just be using two pieces of bitumen instead of one.
