Kevin, I've found it very difficult to locate Corten in the Seattle area and was told by a steel yard that it's probably not worth the hassle and expense of hunting for it. I have low steel walls - 18 to 20 inches in height - that I plan to backfill with gravel and a French drain, as you have. Do you think regular 1/4-inch plate steel will last? How long before it rusts through?

Nickwingy - proper weathering of CorTen is dependent on alternating cycles of wet and dry. If either side of it will be constantly exposed to soil, you might as well use regular mild steel, which is about half the cost of CorTen. https://thecreativeflux.wordpress.com/2015/02/11/what-exactly-is-cor-ten-and-is-it-worth-it/ Be sure to read the links, too!

Boulders - Hi love the design you guys did! Are these faux boulders? How did you get them to hold up the steel are they just set up against the steel wall? Thanks

Did you do anything to treat the side of the steel that is against the soil? Seems like in the NW, this would rust out?

Did you use Cor-Ten? Why or why not?

Those groundcovers are called Selaginella kraussiana 'Aurea'. They are a beautiful bright golden color and do best in shade and moist conditions. I've found that they are not the easiest things to grow.

10. Mix up the materials. In a sloping garden, the materials you use to terrace the incline can be as eye catching as the plantings. Here steel backs plant beds while boulders add visual depth. Discuss your sloped yard ideas with a landscape designer
Carol Bucknell Garden Design added this to Design Workshop: How to Analyze Your Outdoor Site
6. Assess levels. Sloping areas should be noted on the site survey. It’s important to take these into account when planning outdoor living spaces, as seats and tables need a level platform. If your site does have a slope, you’ll have to build retaining walls to create flat areas. Unless you’re really handy, it pays to get professional advice on this. When moving soil around, think about where you could relocate it on the site rather than paying to have it removed.Retaining walls also might be a good option if your site slopes down away from the house; otherwise, the garden will be shady. For areas such as garden beds, rather than creating large, flat areas with expensive earthworks, try to follow the natural contours of your site as much as possible and use low terracing, which is not difficult to build yourself. Tip: Clever planting also can go a long way to disguise sloping terrain.
Lauren Dunec Design added this to 10 Contemporary Retaining Walls Offer Fresh Ideas for Slopes
6. Mixed materials. Sheets of Cor-Ten steel interspersed with large boulders create a one-of-a-kind retaining wall design that almost visually reads as an optical illusion. It’s as if the boulders have been dropped into a sheet of pliable metal, or that the metal has formed around them. The boulders do more than just look cool — they also help anchor the wall in place, pinning down the sheets of steel.
