Our hives are on stands. I built the stands to last. We get a lot of standing water thru the winter here, it rains hard enough, and long enough, the back lot where our bees are will often take 4 or 5 days to fully drain. Untreated wood on the ground will last a season or two, and we would have a terrible problem with water coming in the entrances if the hives were not elevated from November thru end of February. Just as an example, last week I emptied the rain guage on Monday, it was overflowing. Emptied it again on Wednesday, again over flowing. Then the following Sunday, it overflowed again. It's not a large guage, graduations up to 5 inches, overflows after about 6.
There is a reason it's called the 'wet coast'....
