You can use these items to craft 3 of the 4 new blocks.
What is a natural levee and how is it made? -Natural Levees are formed by the river in its process of flooding -A natural levee is formed by a deposit of sand or mud built up along, and sloping away from, either side of the flood plain of a river or stream.
By 1818 the levees were being widened and raised, probably because of the disastrous flood of 1816. The first Orleans Levee Board meeting was held on August 11, 1890 in the Cotton Exchange Building. Felix J. Dreyfous was elected as the first president of the board. The term of office was six years.
