I have been contracted to install a French drain. I have some knowledge but have never actually installed one. There is a 20' gutter that will be running into it as well as a yard drain. I only have 15' between the house and the property line with underground utilities in the same area. The lawn is only a year old and under water all the time side/back 48' by 62'. The back I plan to bring in a substantial amount of soil. Plenty of room to raise grade. The side yard is the problem 15' by 36' no room to raise grade.
