Interesting zoning story: Alexandria Virginia's waterfront is partly made of old ships. They were used to create the fill to build it up along the river. This has created a great interest there in discretionary zoning to ensure discovery and preservation of archeological artifacts https://www.alexandriava.gov/archaeology/four-18th-century-ships #AlexandriaVA #zoning #history #archeology #preservation
Four 18th Century Ships

Archaeologists exploring the Alexandria waterfront in 2015 and 2018, in advance of the ongoing redevelopment, discovered the remains of four vessels that were sunk on the Potomac mudflats in the latter part of the 18th-century.
