In Part 2 of a 4-part series on retaining wall designs, author Carol Brzozowski illustrates two examples where encroaching wave erosion threatens two families’ cherished shoreline residences. In each, Brzozowski describes how site-specific projects can incorporate the effectiveness of large retaining wall blocks as they are linked naturally into shoreline-shaped
