I just found this, Trulia Local - Visual analysis of local data it shows the FEMA Flood Plain maps overlaid on the Austin street grid. So you can see where the areas are that are in risk of flooding.

It may not cover the entire state, but I panned the map all the way up to North to Waco, West to Marble Falls and East to Houston.

Yes, we found when we built City Hall that it sits on 30 some feet of Alluvial soil, i.e. soil that was washed in and deposited from previous floods, below that it is limestone.

The 1930's had some terrible floods in Austin.

"The 1935 Flood, like the others of the 1930s, overwhelmed Austin’s Congress Avenue Bridge. This photo looks north on Congress Avenue toward the state capitol. (PICA 04147, Austin History Center, Austin Public Library)"


The 1938 Flood forced LCRA to open 22 of Buchanan Dam’s 37 floodgates – still a record. (Texas National Guard Photo)



More photos here Floods of the 1930s

Construction started on Mansflield Dam on Lake Travis in Feb. 1937,

Quote:
A severe flood in July, 1938, despite the completion of Buchanan Dam, caused considerable damage all the way to the coast and prompted an investigation into the LCRA’s flood control plan. In a general meeting at the House of Representatives Chamber of the State Capitol, Johnson informed the assembled masses that, “the federal government came in and said it was advisable, if we were to control such floods as we had in 1935 – and last week, to raise that Marshall Ford Dam from 109 feet to 265 feet.”

...The generators at Marshall Ford went into operation on January 27, 1941, and construction was completed in May 1942.

Since heavy rains are predicted today, I thought I'd remind people of this thread and the link above. During the last heavy rains several people who live in flood prone areas were taken by surprise when thier homes flooded. I recommend everyone check the map above to see if any of the areas near them are in the flood plain. Click on the "flooding" button to see the Austin flood plain maps.

Yes I know, thanks, but for some reason I can't get that to work with my Mac Firefox or Safari web browsers. It Keeps telling me I need to install Microsoft Silverlight and then tells me it can't install it because I already have a more recent version installed. So I gave up on it.

The Trulia website works with any web browser and most cities that I have tired to look up in it, And it includes areas outside of Austin's City Limits.

Works OK for me in Chrome on OSX Mavericks.

http://hydromet.lcra.org/full.aspx# 24 hour rainfall, 3 different rain gauges show over 9" of rain just South & SE of Circle C and 5" north of us in the Barton Creek watershed. My rain gauge is over flowing.
