I live in Florida in a 60 year old house. During the summer months, we get a tremendous amount of rain and all of the rain in the neighborhood flows towards my lot. As a result, the ground under the house is wet during the summer and remains damp throughout the rest of the year. My oak floors buckle and I don’t know what other problems this is causing. I’ve cut additional vents to the crawl space but this hasn’t helped. I’m considering installing a fan in one of the vents to increase the air circulation. Does anyone have any experience with this? Should be directed to blow fresh air into the crawl space or should it be the other way around? How about a vapor barrier installed under the flooring? Would this help and if so, what type? Any suggestions will be appreciated.

Had a customer here in NW Ohio who had to dig in a sump crock to eliminate standing water in his crawl. The sump sent it to the storm sewer, not just out into the yard. If there's no water in the low spots....
The poly should help control evaporation up into your floor. You'll want to stop that moisture at ground level.
Don't know much about power venting your crawl, but I would think if you expel the moist air down there, you'll probably be sucking in more moist air. Just a thought.
