IDF Data

IDF Data

IDF Data

(OP)
Does anyone know how I can obtain IDF data from CA Dept of Transportation or CA Dept of Water Resources.  When you read chapter 800 of the Highway Design Manual it states that IDF data can be obtained from them but I can't find anything when I search the web or their respective web sites.  Thanks  

RE: IDF Data

(OP)
the part of california that I'm working in doesn't have data.  It's shaded in the light blue which mean Update in Progress.  When I click on it the link I'm only able to download some PDF's that don't have IDF data.  Am I missing something?  Thanks

RE: IDF Data

Sounds like your study area is limited to the older maps.  You can read the depths from the older maps and transform to an IDF.
