It would be exposure D under UBC/CBC … “Less than ¼ mile from a large body of water.”

Subject: Wind Exposure

 

Let’s say I have a house that’s 600 feet or so from the ocean, West coast.  ASCE 7-02 governs.

 

Between the waterline and the house is a hill, evergreen trees, and other houses.  It’s clearly surface roughness B all around.

 

Question1 :  What is the design wind exposure?

 

Question 2:  would it make any difference if using the 1997 UBC?

 

Thanks,
