@MsJane3 :
@buffaloglenn What say is correct. We received about 55" of rain over 5 days in hurricane Harvey. The San Jacinto river was @ 70' and was flowing over the river bridge to humble washing away the concrete dividers in the center. I live in Fosters Mill and I was 2 1/2' above the 500 year mark and only received a small amount of water ( 1/4") ln part of my house. It was a once in a life time perfect storm occurence.
