[MassHistPres] historic dam removal

[Dennis De Witt]

This site

suggests that, in 2023, the typical solar roof costs $40-60k  

40 houses x $50,000 = $2,000,000

Perhaps your number was in fact competitive.

— and hydro works at night.

I did some quick calculations for a dam on the Third Herring Brook that was removed in Hanover/Norwell MA a few years ago: what would probably be a 2+ million dollar project might produce enough power for 40 homes on average (more in the winter, less in the summer drought).

>>> Has anyone had experience with a privately owned dam in a historic district?  The State is pushing hard for the removal of the 150-year-old mill dam in Ballardvale, Andover.  The dam is owned 50/50 by the abutters and, while one owner doesn't want the dam removed, neither owner wants to cover the costs of upgrading or maintaining the dam.  The State is requiring environmental impact reports, fish ladders and the like.

>>> The dam creates a mill pond that is perhaps the most iconic landscape in Andover.  I think many would feel it would be tragic if the mill pond were to disappear.  Two other dams in Andover were removed years back with plenty of fed/state funding.  One of those dams also had created a pretty mill pond which is now left a marshy swamp filled with phragmites.
