I was digging at my sloped side yard along my house to get rid of the tree roots that might potentially damage the house foundation. After finishing the digging, I realize I effectively create a trench (1' x 1.5'). I can back fill the trench with dirt. Or I can take an advantage to install a french drain there. I never had water problem with my house. Do I really need to put a french drain at the sloped side yard? Or it's just a waste of time and effort to do so? I live in northern California where heavy rain only come several times a year.
