It looks like this change duplicated change set 31069549.

There are lots of seemingly duplicate addresses in this area and the satellite imagery is too old for me to see what the new construction looks like.

Are they really two each of a bunch of these new residential areas?

Most of the objects I have been changing were imported from about or before that time and the changes were to expand obvious abbreviations and assure that the address tags made some sense in relation to the nearby roads. I don't have local knowledge. If you can point me to the specific street and/or street house number affected, I will update. Or, better yet, please make the correction.
