Drainage Issue Archived2000 Walnut Creek Xing Alpharetta, Georgia - AlpharettaThe drainage canal behind my property needs clearing and several trees need to be removed as they have fallen. The drainage canal is clogged with tree debris, causing stagnant water to accumulate. There is a line of trees (Evergreen pines?) that have dried up (parasite?) and several trees have fallen into my property due to the soil being soggy.
