Re: Responsiblity for local conditions

I agree. Earth Systems Consulting here in the desert provides near source values for exact lot locations per the 97 UBC for about $150.00. This is reasonable, but after doing enough of these, you notice that with only one close and active fault, and few areas of expansive clays, the basic near source values are the same. For ten years I've used default values probably boosting my base shear higher than it need be but also taking into consideration that in the end wind probably governs over seismic on the low-rise residential we do in this area albeit less than 5Km from the San Andreas Fault.

Burbank had (and hopefully still has) the City divided into 4 quadrants and had soil tests done for each. They then provided the data for anyone to use upon paying a small fee (less than $100 as I recall) to use the data and to repay them for having the tests done. I believe this was only for residential and small commercial projects.

It has never made much sense to me for an owner to have to pay about $2000 for a soil test for a residential addition when one was done a few months earlier at a site next door or a couple of houses away- and this is what is required in some cities.
