treatment area.
2. Grass clippings and other debris should be kept out of the mulch in both bioretention cells. Please remove
grass ciippings that have accumulated in the mulch.
3. In bioretention cell #2, grass clippings are clogging the rip -rap near the inlet pipe. Please remove grass
clippings and other debris from rip -rap.
