There are definitely some ramifications to this but it was developed by the U.S. Army Corps of Engineers on the East coast of the US and is pretty sound. There is some trial and error to the procedure and even the Army corps cannot get it right every time. There was no noticable problems in the case in point but the process works gradually so there is time to reverse and stop any negative effects in any particular situation. This would be dynamite if the town officials would just engage.
