The SLOCountyKerbs subassembly inserts links and shapes to create kerbs, channels and footpaths according to the County of San Luis Obispo Standard Plan.
You should verify that the dimensions used match your interpretation of the standard plan.
Kerb and Channel:
Kerb:
Detached Footpath:
Integral Footpath:
Attachment
The attachment point is at the Lip (or FS) and the Back of Kerb. This component can be attached to either the left or right side.

Target Parameters
This section lists the parameters in this subassembly that can be mapped to one or more target objects. For more information, see To Specify Corridor Targets.
|
Parameter |
Description |
Status |
|---|---|---|
| Detached Footpath Offset | May be used to override the fixed footpath width and tie the inside edge of footpath to an offset alignment. The following object types can be used as targets for specifying the width: alignments, polylines, feature lines or survey figures. | Optional |
| Back of Footpath Offset | May be used to override the fixed footpath width and tie the outside edge of footpath to an offset alignment. The following object types can be used as targets for specifying the width: alignments, polylines, feature lines or survey figures. | Optional |
Runtime Logical Assignments
The dimensions of the kerb and channel are stored within the subassembly. At runtime the values are looked up and assigned based on the Kerb Type selected.
Output Parameters
None.
Behavior
The initial point is set at the attachment point. The points, links and shapes of the kerb and channel are build based on the Kerb Type selected. The base is then placed under the kerb and channel.
If the footpath type is not set to None, then the appropriate footpath and base is built. If the footpath is Detached and the Detached Footpath Offset is set, then the inside footpath edge is adjusted. If the Back of Footpath Offset is set, then the widths of all footpath types are adjusted.
Layout Mode Operation
In layout mode, this subassembly displays the kerb-and-channel and footpath components based on the input parameters given.
Point, Link and Shape Codes
The following table lists the point, link and shape codes for this subassembly that have codes assigned to them. Point, link or shape codes for this subassembly that do not have codes assigned are not included in this table.
