i need to install a french drain on two sides of my garage to keep it from flooding, but there's a hiccup to the situation. our problem is that our rectangular lot slopes downhill as you go back to the garage -- and slightly to the opposite corner of the lot from the garage -- but our lot backs our neighbor's, so i can't have the drain pipe emerge from the ground and drain out. grr!
anywho, my idea is to take the end of the french drain after it "L"s around our garage and send the pipe to a large retention pond (read: hole) i'll dig at the corner of our lot -- about 3 feet in diameter and 3 feet deep. i'll feed the drain pipe into the pond and fill the hole with gravel or coarse sand to give the water from the drain somewhere to go that's below the level of our garage, but not directly into our neighbor's yard.
will this idea of creating a destination for the water solve my problem or create a totally new one? any suggestions will be appreciated.
