This was affecting drainage from the backyard and was even washing away some of the yard itself. There was concern that the water could seep under the steps into the foundation of the house. With an old house like this, your worst enemy is water near your foundation. With the replacement though, there have been many rainfalls and it has worked great to keep the flow of water where it should be. With minimal cleanup once in a while, this is a definite improvement to the previous sidewalk gutter.
