We just happened upon this most excellent page at Chester County, PA’s website discussing maintenance of stormwater facilities.  A good reference.

As winter has set in hard in the Mid-Atlantic and Northeast, thought we would throw in a photo of recent memories of Autumn….  An in-stream detention facility we have recently evaluated in an effort to reduce the  environmental impacts of maintenance.
