It appears that the city, state and feds are teaming up to in essence destroy the Ridgewood Reservoir.
The excuse is that after Sandy, the rules were changed so that structures determined to be classified as dams, such as the reservoir, need to be breached in order to be decommissioned for other use. The reasoning is that a catastrophic storm could fill up the basins and cause them to overflow.
If it ever rained so hard that the basins filled up with rainwater, we'd be facing a lot bigger problems than overflowing, don't you think?
