Shoreline Protection
• Natural Vegetation• Bioengineering• Riprap• Seawall with toe stone
The proposed structure fulfills an identifiable need for erosion protection, bank stabilization, or the protection of uplands.
![Page 8: Shoreline Regulations Inland Lakes and Streams and Great …Part 301 Lake: Natural or man‐made, permanent body of water 5‐acres or more in size. Stream: Any body of water that](https://reader033.vdocuments.us/reader033/viewer/2022060314/5f0b8aa57e708231d43106ae/html5/thumbnails/8.jpg)
Shoreline Protection Projects
• Shoreline protection can be effective at stopping erosion and preventing further erosion.
• Shoreline vegetation protects property naturally, effectively and inexpensively.
• Bioengineering methods can effectively protect highly vulnerable shorelines.
• Riprap and seawalls provide shoreline protection, but reduce the natural shallow water habitat.
![Page 9: Shoreline Regulations Inland Lakes and Streams and Great …Part 301 Lake: Natural or man‐made, permanent body of water 5‐acres or more in size. Stream: Any body of water that](https://reader033.vdocuments.us/reader033/viewer/2022060314/5f0b8aa57e708231d43106ae/html5/thumbnails/9.jpg)
• The DEQ will evaluate the site conditions to determine appropriate shoreline protection.
• Review will include• Existing on‐site natural resources, i.e. wetlands, fish and wildlife habitat, woody debris, and natural cobble in nearshore areas
• Extent of erosion and need for shoreline protection
• Use of Wisconsin Erosion calculator

Bioengineered Shoreline Protection• Creates long‐term shoreline
protection
• Attractive native plants can be used as part of the structure
• Bioengineered structures may incorporate some riprap and fill
• May be permittable along some wetland shorelines
![Page 12: Shoreline Regulations Inland Lakes and Streams and Great …Part 301 Lake: Natural or man‐made, permanent body of water 5‐acres or more in size. Stream: Any body of water that](https://reader033.vdocuments.us/reader033/viewer/2022060314/5f0b8aa57e708231d43106ae/html5/thumbnails/12.jpg)
Riprap Shoreline Protection• Riprap dissipates wave
energy
• Retains shallow water habitat values found in natural shorelines.
• Riprap provides habitat for aquatic insects, fish and wildlife.
• Provides loafing and basking areas for frogs and turtles.
PLANNING CONSIDERATION: Riprap provides a feasible and prudent alternative to seawalls.
![Page 13: Shoreline Regulations Inland Lakes and Streams and Great …Part 301 Lake: Natural or man‐made, permanent body of water 5‐acres or more in size. Stream: Any body of water that](https://reader033.vdocuments.us/reader033/viewer/2022060314/5f0b8aa57e708231d43106ae/html5/thumbnails/13.jpg)
Seawalls• Types: Vinyl, steel, wood,
stacked rock
• New seawall applications are not considered a Minor Project
• Applications for new seawalls require a $500 application fee and Public Notice processing
• Only replacement seawalls are covered under the Minor Project category no. 33
PLANNING CONSIDERATION: Riprap provides a feasible and prudent alternative to seawalls.

Natural Resource Impacts From Seawall Construction
• Loss of shallow water habitat values
• Loss of natural shoreline habitat
• Increase erosion on neighboring properties.

Why are the Great Lakes water levels so low?
Long‐term weather patterns!
Below average snowfall = reduced spring run‐off
Limited ice coverage during winter = increased evaporation
Warmer than average water temperatures = increased evaporation
![Page 18: Shoreline Regulations Inland Lakes and Streams and Great …Part 301 Lake: Natural or man‐made, permanent body of water 5‐acres or more in size. Stream: Any body of water that](https://reader033.vdocuments.us/reader033/viewer/2022060314/5f0b8aa57e708231d43106ae/html5/thumbnails/18.jpg)
