Water in my basement

I have lived in my home for 38 years and this is only the 2nd time to have any water in my basement. My den, utility room, spare bedroom and garage had some visible water after almost 7 inches of rain Fell in about 12 hours. How much is this? Near my home is a football and 2 soccer fields. If you watched the news the pix of the football field it shows water almost up to the cross bar of the field goal. That is over 6 1/2 feet of standing water. There was water in homes that had never had water them! We lost some rugs and carpet, but we were on it right away and hopefully with fans and drying all Should be well.. Wish us luck. Jeff
