Tiering a very steep slope - need idea please!
Hello everyone - this is my first post, so I hope I get all the photos loaded in correctly!
My husband and I live in a 110 year old home that was moved onto a hill in 1936 from it's original site. We are surrounded on two sides with fully mature trees, and a very steep slope that is causing some drainage issues for us. We'd like to tier it out. We have an idea of making it into three total tiers, and using either washed limestone rock (which was heavily used at one time in our area, and therefore the tiers would look just like all the retaining walls in our area) or doing something perhaps with railroad ties. The thing is, I think we don't know what we don't know about designing the tiers (how big, how many, etc) and I'm worried that as we DIY this, we're going to muck it up. We'd like at least 1 tier to be big enough to have a seating area, and the rest of the area we want to plant with perennial. If anyone has some ideas, I would love to hear what you've got!!
This is the area in question - we own approximately 6 feet beyond the tree line, and hope to take some of that out to clear out/level the top of the slope. The area immediately to the right of the shed will be leveled out and our children's wooden playset will be here.
Another view of the slope from our back patio.
Finally, the view from our driveway. We have a septic system immediately in front of us (it's the type with no leech lines, though), and the wall is close to 5' high.
So, our priorities are these: 1 - Fix the drainage issue 2 - Have seating area 3 - increase usable area of lawn 4 - incorporate perennials and ground cover for low maintenance.
Thanks everyone! I'm enjoying all the great ideas/advice here so far!
