My slope is not drastic. It has a slight drop on the north side, and the east side has the largest drop. This is going to be 4x8. The north side is about 9 inches approx 19% slope and the south side 8 inches approx 17%.
The 4ft sides will be running east to west. I found a picture that will give you an idea of what I am going to do. This does not appear to be a rectangle, and I probably won't build up the high side quite as much. Originally my plan was to remove the soil and build the rectangles from the bottom up. Living in Mobile, the less wood below the surface would be a much better idea with our humid and rainy conditions year round. I entertained the idea of using concrete blocks, but on a slope I decided I would will just live with the fact that the wood may only last a few years. This is strictly for vegetables not ornamentals.
I spoke to a longtime friend who is a professional landscaper who deals with irrigation & major landscaping work. He said there are many ways to build this using 4x4x8. He told me as a standard they usually will remove 2 inches and place the first level. So with using 4x4 it will leave approx 1 1/2 above the soil level. I could just place 1 or 2 on the high side and go from there. They talked about staggering the sides. I tried several times to find a you tube video and the majority build on top and use 2x6 up to 2x10. Here is a picture of what I would like to try to do, and keep in mind this is a square and I am building a rectangle. I don't intend on building it quite as high. Perhaps one less layer. I am just trying to figure how to go about this. I understand it has to be built level. Again my original plans was to lay it out & build from the bottom up using a preconstructed 1st layer get it level & build up from there by screwing in the other layers on top of one another & then drilling & using 1/2 rebar.
If you know of a video or illustration please post it. Any and all advice would be appreciated.
