7a(1). CREATE A MARSH, PROTECT THE TOE WITH A FIBER LOG
Shallow water depths allow the conversion of subtidal waters to intertidal area with a minimum of fill, and the marsh created is more likely to persist than it would in a deep water situation. Marsh creation will increase the intertidal width, and vegetation will help reduce wave energy. A fiber log at the toe of the marsh may be necessary to hold fill in place, if used, until roots from the plants are fully established. If the shoreline is forested, the effect of shading on the created marsh area should be considered.
