Hydrojetted area drain and removed large amounts of dirt and rocks. Performed inspection and found that several of the drains located in the backyard were either broken or backgraded leading to issues of flooding when a heavy rain occurs. Recommend digging up and replacing approximately 50’ of area drains in backyard. Also recommend diverting rain gutters directly into its own drain and adding another 4 drains in backyard to catch run off from backyard.
