The Conservation District, confirmed by PFBC, indicates the Bethlehem Water Authority has a 3 year plan to clear the berm around the wastewater plant, and that according to best maintenance practices, they never should have allowed large trees and shrubs to grow there. I can understand clearing the berm, a reasonable, tho perhaps unfortunate undertaking 50 or so years after the fact for the trees cut. However, if you've been there, you'll see that in addition to the trees actually on the berm, every other tree was cut as well. There are a few shrubs starting to poke through and, of course, the Japanese knotweed is in the process of colonizing the whole place.
The 3 year plan means that the berm and whatever else they qualify as "berm", will be cleared of trees from where they stopped now to below the confluence with the East Branch.
When/if I get any more information/clarification, I'll pass it along.
