Reported by Kip Patterson:

A construction company has been hired to remove material from the creek bed near the Lenappe/Overbrook culvert to alleviate the problems resulting from stormwater runoff during heavy storms. This means equipment in the stream. Muddy waters will be seen downstream. [Tina Mohn, Property Manager, Columbus Recreation and Parks is aware of this work.]

It looks like much of the material being removed is native rock. There is also a surprising quantity of broken tile, bricks, old paving material, concrete, etc. Steel plates protect the forest floor and the workers seem to be doing a good job of avoiding overhanging branches.
