NE Storm Flooding - Advice Needed!

The NE storm's 7" rain caused ground water to rise in our dirt floor crawlspace, then migrate to an adjacent finished and carpeted room on the same level. This was the first time we've seen this in 40 years. Can I just hope to stay lucky for another 40 years -- or at least 'til the next 7" rain? Or will this occurrence mean that a flood's now more likely to happen again, even with less than a 7" rain?

There's no obvious problem outside with drainage, etc. No signs that the water came through the walls. Maybe a sump & pump in the clay floor would help. Maybe it would do more harm. Anyone know about this?

It would take a crystal ball to see what the future has in store. Water tables do tend rise during periods of heavy rain. In areas where homes were built when water tables were low during times when local industry or mines pumped lots of water and kept the water table low, there were no issues with the water table. In many areas where industries or mines have closed,the water table has risen over the years. Then, during periods of heavy rain, the water table poses potential problems for homeowners. Homes built in areas where there was a period of prolonged drought will also experience no problems until there is heavy rain.

It's like predicting a 100-year flood. Some report they live in a 100-year flood plain and the last time it flooded was 1985. No one is around to verify that the last time it flooded before that was 1885. So, they naively believe their property is safe again until 2085. It may or may not flood again until 2085, but chances are likely that it will flood again before then, especially in view of the fact that stream beds are filling with erosion from mining and mountain top removal, logging, and other events that impact the environment.
