Tell you what Lashlander that makes a good looking sheet pile wall. Using sheetpile for your tie-backs is way nicer that using drilled tie-backs and I suspect way quicker. I would be ashamed to show you what the 1100' of seawall we installed last year looks like. One of the worst engineered projects I have ever been on. Not 1 geo-tech boring along the entire alignment of the wall, relied on historical data for the alignment. We hit edger trimmings 5 to 15' deep, old wood piles, 4' Cedar and Fir logs, you name it we hit it. We finally got it in, but it ain't pretty.
