Use these subassemblies to design channels, trenches, and retaining walls.
| Image | Subassembly | Common Uses |
|---|---|---|
|
Channel: Trapezoidal channel with optional lining and backslope links. Marked points are placed at the ends of the backslopes so that other corridor components can be tied to them. Default Tool Palette: Trench Pipes Subassemblies |
Roadside channels |
|
ChannelParabolicBottom: Similar to Channel except that the bottom is parabolic in shape. Default Tool Palette: Trench Pipes Subassemblies |
Roadside channels |
|
Ditch: Flat or V-shaped ditch with user-defined horizontal and vertical control parameters and an optional lining material depth. A parameter can control whether the ditch is inserted in cut, fill, or either condition. Default Tool Palette: Trench Pipes Subassemblies |
Roadside ditches |
|
SideDitch: Simple ditch with parameters for bottom width, sideslopes, and optional foreslope. You can also specify a ditch wall depth for lined ditches. Default Tool Palette: Trench Pipes Subassemblies |
Roadside ditches |
|
SideDitchUShape: U shaped ditch with variable wall thicknesses. Benches can be specified inside and outside the ditch as well as an optional foreslope link. Default Tool Palette: Trench Pipes Subassemblies |
Concrete-lined ditches or channels |
|
SideDitchWithLid: Similar to SideDitchUShape except that a lid can be included and the side slopes of the ditch controlled through input parameters. Default Tool Palette: Trench Pipes Subassemblies |
Concrete-lined ditches or channels with grates or lids |

RetainWallTapered: Retaining wall with one tapered side and an optional key. The vertical side is always faced to the low side and the elevation of the footing is based on a target surface and specified cover requirement. Default Tool Palette: Retaining Wall Subassemblies |
Retaining walls |
|
RetainWallTaperedWide: Similar to RetainWallTapered but typically used for high retaining walls (18 ft or higher). Default Tool Palette: Retaining Wall Subassemblies |
High retaining walls |
|
RetainWallTieToDitch: Retaining wall with optional barrier, shoulder, walk area, and the ability to tie to an existing ditch. Default Tool Palette: Retaining Wall Subassemblies |
Urban areas where the retaining wall is adjacent to a ditch or walk |
|
RetainWallToLowSide: Similar to RetainWallTapered except that all of the footing is located under the high fill side. Default Tool Palette: Retaining Wall Subassemblies |
Retaining wall where there is limited space on the low fill side for the footing |
|
RetainWallVertical: Similar to RetainWallTapered except that both sides of the wall are vertical. Default Tool Palette: Retaining Wall Subassemblies |
Vertical retaining walls |
|
SimpleNoiseBarrier: Creates a trapezoidal noise barrier with the ability to tie the back of the barrier into an existing surface. A topsoil thickness may be applied. Default Tool Palette: Retaining Wall Subassemblies |
Noise barriers or berms |
