IRC Requirements for Site Grading

[Konrad]

Hi all,

I have an attorney friend who asked me questions about site graading around a single family residence. (Water in the basement)

Our locale uses IRC 2000. I can't find anything in there about minimum positive drainage away from the structure, but I'd swear there's something in there somewhere.

Anyone?

6" fall within 10' of foundation except where the slope can not be created, drains or swails need to be provided.

R401.3 Drainage

Hi,

It's there. According to my 2000 CodeCheck it was:

IRC 401.3 - Surface graded away from foundation min. 6in/10ft.

IRC 4031.7 - Setbacks & clearances to slopes > 1 vert.: 3 horizon.

IRC 403.1.5 - Lot slope > 1:10-Foundation stepped or level

IRC 403.1.7.3 - Graded site - top of foundation min. 12in + 2% above street drain

ONE TEAM - ONE FIGHT!!!

A word of advice. You can offer your services to your friend the attorney and make some $$ as you know that he will be making $$$id="size4"> off a wet basement case!
