Tiered Retaining Wall on Cross-Slope: Pavestone Blocks Work

House 2.5 ft above neighbor. East-west slope shaded by oak. North-slope also. 6 ft from drive to property line. Wants tiered Pavestone wall.

2.5 ft in 6 ft = 42% Slope — Tiered Wall Is Perfect

Single 30" wall is heavy, needs deep footing, geogrid. Tiered (2×15" or 3×10") is:

• Easier to build.
• Less engineering.
• More planting pockets.
• Visually lighter.
