I don't understand how "unpaving" the airport's runway could have affected those homes. There was more runoff when the paved runway was in place—a
huge "impermeable surface". However, one noisy homeowner with a noisy sportscar insisted that the dirt road
that runs directly behind those homes got a "pave-over". 
(An impermeable surface
right there).
Erosion works both ways. Runoff moves soil downhill towards the lake, then wakes from oversized boats chew away at the lowest layers of shoreline soil. Uphill soil fills that void through rain.
Also, note the two large-diameter PVC pipes draining runoff that's accumulated under the house to the edges of the lot. (And that there are no stumps or trees in front of the house).
BTW I: That concrete base repair in the lakefront photo is
also subject to eventually falling into the lake—an example?
Parking was built behind a cottage in a nearby small lot. (That lot was made into a "micro-lot" by the spec-builder: the two homes share a well and a leachfield: worse yet, the "micro-lot" has a huge driveway easement leading to our latest spec-built McMansion).
Shortly after construction, that relatively tiny new space has caused two large trees to die—increasing erosion around that space—and the tiny new parking area is sliding towards the lake.
As you can see in the below photograph, the blocks are no longer aligned after just two years. I haven't looked at it
this year.
BTW II:
A week later, the "unseen boat" returned leaving a similar wake: It was an "Express Cruiser".
