I'm not a pipeline expert, but I think it was mostly done by the mid-1960s.
Recent enforcement aside, I think the
@super7's point is you can now
see the
right of way. The trees had screened it very well. The train trestle also has trees to screen the view of the pipeline. All the more reason to "maintain" the ROW with whatever low-intrusiveness landscaping is allowed.
edit: I haven't seen the landscaping plans or tried to figure out how much room they will have... but meethinks if there's a way to plant a line of screening trees between Finnegan and the ROW, they will do it. From a landscaping perspective, trees are almost like flowers now-a-days. I definitely can see them dropping fairly mature trees in strategic locations in a balance of cost with making the area seem "established..."
