Novato, the town this property stands in, in 3 storm reports between 1998 and 2014: 3 flash flood.
No death or injury is recorded in these reports. Each account below is quoted exactly as the forecast office
filed it, from the NOAA Storm Events Database, and each date
opens the federal record of that event.
Heavy rainfall produced significant rises on Novato Creek between highways 101 and 37 on the east side of the city of Novato. This led to an intentional breach of the levee on a 20 foot section to prevent floodwaters from reaching downtown businesses and nearby subdivisions. This same flooding also resulted in failure of a smaller portion of the levee and overtopped another section. Caltrans levees on highway 37 were breached and a culvert was washed out.
