I like a good Doomer story as well as the next fellow, however, I think the authors focus overly-much on Sacramento and the Central Valley.
The idea of an Ark Storm where multiple storm-cells go barreling down the same track in rapid succession is not unprecedented.
On January 10, 1862, Leland Stanford was inaugurated as the governor of California, traveling by rowboat to the ceremony due to severe flooding in Sacramento. The Great Flood of 1862 had caused extensive damage and disruption across the state.
The difference between then and now is that men built so many structures in areas that are subject to extreme-but-infrequent flooding. To me, the more exciting story is in Los Angeles County. Of particular interest are choke-points:
 |
| East end of the San Fernando Valley |
 |
| Culver City |
 |
| Whittier Narrows |
While the water might get deeper above these choke-points, the water velocity will make these places more dangerous than the places with deeper water.
Another area of concern are where limited access roads are sub-grade.
