“. . . The phrase ‘I didn’t flood during Allison . . .’ doesn’t mean anything. Most of Houston didn’t flood in Allison either because they didn’t get the large volumes of rain that portion of the city received.
Many areas of Houston flood during minor summer storms, but didn’t flood during Allison. It always just depends where and when the rain falls and also if the runoff compounds downstream.” [kjb434, commenting on Riverside Terrace Stucco Redo, With or Without Garage]
