Hurricane Irene (August 28, 2011)
Followed by Tropical Storm Lee (September 8, 2011)

Overall, the restored streams in Reston performed very well during these back-to-back storms. (Tropical Storm Lee was classified between a 200- and 500-year storm event!) The reaches with more mature vegetation handled the flood with no issues, while some portions of the younger reaches need minor repairs, as expected, since the tree and shrub roots have not had time to reinforce the soil. WSSI and RA staff post-storm inspections are complete, and crews are already mobilized to address the minor repairs.
