eventually. you'll end up removing and redoing it eventually.

to prolong this, you can make a wrap to give more filter surface, and use a proper landscape fabric. a double punched non woven fabric is what you want. 4oz is a happy medium, less will allow more flow but isn't as heavy, 6/8, and higher oz will be less permeable and won't pass water as quickly.

to be fair, you don't use a French drain to take care of surface water. op should just run a trench that can be easily cleaned if maintenance is priority and ground water isn't a concern. can run a French drain underneath if needed.

in a French drain you ALWAYS want to use a fabric. even in heavy clay. again, many people are better served by proper slope and surface drains for the bulk of their water, which prolongs fabric health.
