I had never saw a .prj with a METADATA node until now. Oh well... It just 
seems to indicate NAD 83(2011) and the 4 first parameters of METDATA are the 
bounding box in long/lat of validity for the SRS.

If you don't need a very accurate reprojection, you could just use -s_srs 
"+proj=longlat +datum=NAD83" in ogr2ogr.

If you need very accurate reprojection (let's say error < 1 meter), you could 
go with the tutorial at https://trac.osgeo.org/proj/wiki/HTDPGrids . But that 
will be much more involved.
