Comments:
Slope flattens toward end of much steeper narrower valley here as stream enters Chelsea village, but overall slope for segment is ~4.1 pct (GIS calc.). Series of frequent recent flood events starting with ice jam in 2007, then local microburst storms in 2008, 2009, 2010; Irene in 2011 was actually less of an impact than these more localized events. Much riprap has been recently installed or replaced.
