Datum, winds reported are at 10m AGL, so other than "windshear' there is no other reporting (currently) of the level of the windshear or the defining change.
When a pilot tells ATC they encountered windshear, usually as the reason for a GA, ATC broadcasts that until someone says they did not encounter windshear. In reporting winds, the 2min average based on 1 min readings is what is reported. Gusts are on a 10min average, unless the gust exceeds the average, then 5 minutes is used. I have no idea why gusts are reported this way. It should be understood that these measure the horizontal winds only, not the vertical winds, so a vertical windshear component cannot be measured.
Wind profilers show the winds aloft, providing details of the windspeed/direction (horizontally and vertically) and can be used to report exactly what the level and shear conditions are. How to use this information is under development.
As noted by several others, RW12L is about the least likely to encounter a wake. The conditions were right for a dry microburst.
In regards to structures, the low level ground turbulence is usually so scrambled, that structures contribute little, terrain has far more influence.
