Investigation of a Shoreline Enhancement Technique for Wetlands Impact Mitigation
An attempt was made to mitigate the impact of highway construction on a wetland (beaver pond) margin by enhancing the shoreline of the roadfill. One hundred 20' long finger-like extensions 10' wide were constructed 10' apart along the roadfill. The extensions increased the pond-roadfill margin by a factor of 3. In addition, weeping willows and blackwillows were planted on the southeastern edge of the fingers. Despite the repeated destruction of the beaver dam by county surveyors, and two successive drought years, the procedure appeared successful. Recommended modifications of the shoreline include making the fingers longer and wider, the sloughs wider and deeper, and erosion control and less slope to prevent excessive sedimentation.
