Retaining wall requirements for land development will vary depending on local building codes and zoning regulations. However, some general requirements include:
1. Height limitations: The maximum height of a retaining wall may be limited by local regulations to maintain stability and ensure public safety.
2. Drainage: The retaining walls should be designed to allow water drainage and prevent standing water behind the wall.
3. Materials: The materials used for constructing retaining walls should be appropriate for the soil conditions and provide sufficient strength to support the soil behind it.
4. Slope stability: Retaining walls must be designed to withstand the pressure from the soil and ensure slope stability.
5. Location: The location of the retaining wall should be reviewed and approved by the local planning department as the wall could impact other properties and public infrastructure.
6. Design and construction: The retaining wall should be designed and constructed by a licensed and experienced engineer or contractor who follows all local building codes and standards.
