No, this is a misunderstanding. The "rain garden" or bioswale DOES 
drain. It is constructed by excavating a hole about 4 feet deep and 
laying in layers of various materials (I believe we used pea gravel, 
coarse sand, and vegetable compost, but NO MANURE, along with the 
local clay). It is NOT COMPACTED. I have almost never seen any water 
standing on the surface. The whole point of it is to soak away excess 
runoff to prevent it getting into the storm drains -- the county 
didn't care that there are no storm drains on this road, of course.
