@jhutson made a very valid suggestion:
- "Have you talked to some geotech folks that could advise whether there are any options to 'stabilize' the bluff and stop / reduce the rate it is eating away at your home?"
I found the following link from the University Of Minnesota Extension:
As per your post you are in Michigan.
Even though this article is from Minnesota it seems to provide some insight into preventing erosion as it is titled:
- "Stabilizing your shoreline to prevent erosion"
Below is some information from the article:
"Erosion of higher shoreline bluff areas can be prevented by:
- retaining moisture-absorbing vegetation on the bluff
- outletting rain gutters and diverting surface runoff away from the bluff
- reducing runoff rate toward the bluff
- minimizing paved areas that increase runoff
- limiting ground water flow toward the bluff
- installing septic systems and drainfields away from the bluff
- avoiding additional weight on the bluff edge, such as pools, buildings, or storage sheds"
As per your post:
- "It is heavily wooded between the back of the park and the river."
Thus, you have #1 down already:
- " retaining moisture-absorbing vegetation on the bluff"
The article also states:
"Potential shore protection alternatives include:
- bulkheads (retaining walls)
- gabions (rock-filled wire baskets)
- articulating blocks (cable-connected concrete blocks)
- Geoweb matrix (thick, open-cell plastic grid)"
We wish you the very best!
