Nice touch, maybe there is a silver lining here for us after the storm in Washington State.

could happen here.
In fact it has several times along Maine's coast and inland rivers. The 3" quality image lets us know, there must be a reason why the development has progressed the way it did.

The LiDAR image below shows why! An old landslide occurred in Westbrook and we have developed along the banks, the banks of the river that caused the original slide, and on the lowlands next to the river.
This is just one of the many uses of LiDAR that shows its value. Notice the little hummocks in the center of the slide area and the drainage path created by runoff from the site.

And this is what we can see with the old 10-meter USGS topographic data.
