Stop the Erosion and Start Enjoying Your Shoreline!
If you’re looking for long-term protection against shoreline erosion, nothing beats riprap – specifically 6- to 24-inch-diameter fieldstone riprap.
When combined with the right thickness of filter-fabric and professional installation, a fieldstone riprap shoreline defies erosion and Father Time better than anything else can. It will probably outlast you.
The Michigan Department of Natural Resources (DNR) has set forth a series of guidelines that they believe should be followed when constructing a proper “DNR-approved” riprap shoreline.
What are the DNR criteria?
- Riprap should not cover existing vegetation, such as cattails or bull rushes.
- Riprap should be made of natural rock, 6 to 30 inches in diameter.
- Crushed rock, gravel or filter fabric should be placed underneath the riprap.
- Riprap is not more than 6-feet waterward of the Ordinary High-Water Level.
- Riprap conforms to the natural shape of the shoreline and does not obstruct navigation or water flow.
- Minimum finished slope of riprap is no steeper than 3:1 (horizontal to vertical) whenever possible.
- Area adjacent to the shoreline is not a posted fish-spawning area, or designated trout stream.
