This Amtrak document was obtained by Roger Hannigan Gilson and included in Amtrak’s Secret Plan to Fence Off Parts of Hudson River, published on Jan 3, 2021.
As usual, Amtrak’s work is exceedingly sloppy. On page 22 they show a map of their proposed fencing at Anchorage Rd./Ernest R. Lasher Jr. Memorial Park in Germantown. On the map the green line denoting fencing covers an distance of about 120′, whereas the label for that fencing mentions 685′ of fencing. One of the two is completely wrong.
