So I have one more drainage task I need to get done before the winter rains arrive in the southeast. I need to backfill around the back door of my addition. This is a special challenge because LOTS of water, comes to this point. Essentially the entire half of our lot to the right of the driveway edge comes through that point.
My plan for this is to pour a curb (yellow line) to direct all that water into the 6" corrugated pipe that will bring the water out through the cinder block wall I will build (purple line). Luckily the slope works all the way out and down the hill to the left along the back of our screen porch. It is hard to see in the picture but the natural slope of the land is gently sloped to the left in the picture. I used 6" because in the worst of a rainstorm a LARGE volume of water moved through here. I think 6" should be enough for 98% of rain events. For the other 2% I will make an overflow gutter that runs along the garage and pour over the wall (green line). Does anyone have issue with this being corrugated? I want it to be cleanable and accessible. The 90's I got are essentially a T with one side closed. I hope to find a solution to add a clean out where that 6" comes out of the wall.
The 4" rigid is coming from the front of the house. One is a freedom drain that runs along the front and side of the house. It is perforated until the corner of the house and then solid until it joins the other pipe. The lay of the land there is such that any extra water that comes that direction will naturally drain out the corner of the house to daylight. The other 4" rigid is a surface drain from the front corner of the house that catches the gutter water from the front of the addition and the little bit of roof that is that little jog in. It is not obvious in this pic but as that 4" comes out from the corner of the cinder wall there will be a Y that will allow me to add a clean out. The upstream end of the pipe is very accessible as well. This 4" will then turn and run along the back of the house, eventually catching another surface drain from the front of the house and the gutters from the entire back of the house.
There are obviously 2 spot I will need to leave a void in that cinder block wall to allow these 2 pipes to come through. I plan on using a metal lintel under these cavities. I plan on gluing the cinder blocks together and then using Quickcrete Quikwall. You basically dry stack the blocks and then smear this stucco like substance on the wall and they hold together.
All of this water will be dumped towards the back corner of my property.
Does anyone see any issues with my plan? Questions, concerns, comments? I think it is solid, but I have learned one thing. If you want to find the chinks in the armor of any plan, post it on TBN and someone will have an issue with it
