A townhouse community I maintain has a underground spring that leeches through one of the beds at the entrance of the development. The guy who installed the landscape said he has dug it up several times and put in sand, gravel, etc. but to no avail. It wouldn't be so bad, but it comes out over the curb and puddles right there in the road, which happens to be a low spot. Any suggestions for getting the water drained away from the road?
