5b(1).MANAGE RIPARIAN BUFFER AND MARSH VEGETATION TO PREVENT FUTURE EROSION
A low fetch (less than ½ mile) supports the formation of small waves, which is the ideal wave climate for marshes. Maintaining the marsh at this site may require thinning of tree branches to maintain light levels and removal of storm debris (wrack, tree limbs, wood, trash, etc.) that could smother the wetland plants.
Even in low fetch areas, frequent, fast-moving boat traffic can generate erosive boat wakes. If the marsh toe is actively eroding, the fetch should be more accurately described as moderate (due to extensive boat activity), and a sill may be necessary.
