Retaining Wall maintained by King County Roads Division

For more information about this layer please see the GIS Data Catalog. Retaining walls are structures designed to restrain soil to unnatural slopes. They are used to bound soils between two different elevations often in areas of terrain possessing undesirable slopes or in areas where the landscape needs to be shaped severely and engineered for more specific purposes like hillside farming or roadway overpasses.如需了解该图层的更多信息，请参阅地理信息系统（GIS）数据目录。挡土墙是旨在将土壤约束于非自然坡度的工程结构，常被用于在两种不同高程之间固定土壤，多用于存在不利坡度的地形区域，或是需要对地貌进行大规模改造并针对坡地耕作、道路跨线桥等特定用途开展工程设计的区域。
