Hallo,
I am going to reply here to your comment in https://openstreetmap.org/changeset/56807998 because here I see a large island of dry land newly carved out from the basin area Addicks Reservoir, along with a few highways.
the problem here and in the parks you carved out there, is that they can be clearly seen all to be under mucky brown water in satellite imagery of 31.08.2017.
What your changes are implying is that (which I doubt) there have been massive earthmoving projects to add several metres elevation to the roads and the park areas to elevate them out of the flood-susceptible basin as defined.
The aeroport, also seen to be underwater, lies on the other side of an administrative boundary which, without looking at the entire history of the area, may be the basis along with the marked Addicks Dam area, of defining the basin.
I see here that the Reservoir is in its 39th iteration of change, along with the need for the note= added to it, so I am reluctant to take the present heavily-edited boundary as representative of its original intent in OSM.
Unfortunately, the satellite imagery from 30.08.2017 that covers the southwest area where a residential area appears dry today in OSM, has too much cloud cover over top of what looks to me also to be mucky floodwater. -

Satellite imagery taken half a year ago during Hurricane Harvey? Your using imagery from a hurricane that was unprecedented in this region? That couldn't be a more extreme outlier. My edits imply that developed land is treated consistently, without preferential treatment given to cooperate, residential, or recreational.
What are you viewing the historical map data from six months ago on?
