Location

Approximate location. The original knotweed infestation at this location was reported on 6/9/2009 (rpt 356). It appears that the original bush(s) have been mowed or removed. However, there is now a stand of numerious 18"-24" shoots between the fence and edge of pavement at this location. Infestation is quite obvious from west bound Belt Line Hwy.
