Better drainage now, especially in LA.
My father went up to L.A. in 1916 durring that flood.
He was going to San Diego High and had to take a boat across the san Diego river to get to high school
There was so much water that it couldn't get out between the gap between Elysian Park and Mt Washington and all of Atwater, and most of Eagle Rock and south Glendale was under water.
It was up to the ties of the street car trestle at Riverside Dr. and Fletcher.
Where our office and warehouse is was under 80 feet of water.
Maybe not. I recall articles to the effect that the Army Corps of Engineers has told California repeatedly that the state's levee systems are inadequate.
