1. Soil type and stability: The type of soil, its stability, and potential for erosion should be considered during the design process. The wall should be designed to withstand lateral earth pressure, sliding, overturning, and settlement.
2. Drainage and water management: Adequate drainage is crucial to prevent water buildup behind the wall, which can cause instability. Proper drainage systems such as weep holes, drains, and geotextiles should be incorporated into the design.
3. Height and slope: The height and slope of the wall should be proportionate to the soil conditions and the purpose of the retaining wall. The taller the wall, the more reinforcement it will require.
4. Materials and construction methods: The type of materials used and the construction methods should be appropriate for the site conditions, aesthetic considerations, and budget. Common materials include concrete, brick, blocks, stone, and timber.
5. Local codes and regulations: The design of a retaining wall should conform to local codes and regulations such as the International Building Code, local building codes, or local zoning ordinances.
6. Environmental impact: The design of a retaining wall should minimize the impact on the environment, wildlife, and surrounding ecosystems. The design should ensure that the wall does not interfere with drainage, water flow, or cause soil erosion.
7. Aesthetics: The design of a retaining wall should blend well with its surroundings and be visually appealing. The materials, colors, and overall design should match the architecture and character of the building and landscape.
