Evaluate (including/not limited to):
• Displacement of stones
Settling
• Scour/Erosion
• Vegetation (especially marsh inventory)
• The Town bulkhead deterioration
• The adjacent property owners' existing
bulkheads and shorelines. (Future
actions may include extending the sill
landward establishing a protective
revetment.)
Expediently address deficiencies
