STONY CREEK MARSH ISLAND
30% Draft Design Compared to Feasibility Design
• Based on publicly
available NOAA data,
awaiting higher
resolution topographic
survey
• High resolution
bathymetric data
indicated significantly
greater offshore depths
when compared to FS
study data- yielding
decreased restoration
acreages and increased
sand volume needed
• Preservation of healthy contiguous existing marsh,
assumed to be at or near lower end of design elevations
