minimum of three diverse species of herbaceous,
native vegetation at a minimum density of 50
plants per 200 SF of shelf area (3,200/200 =
16*50 = 800 plants). Use equal parts Joe-Pye
Weed, Swamp Milkweed and White Turtlehead.
3 - Trees and Shrubs may be planted outside of
the embankment slopes and can serve to shade
the wet pond, along the south, east and west
