Curb type has not been selected at this stage of the project and will be done in final design. However, curbs used in the roundabout will need to meet Caltrans Standards and will likely vary based on the application and will be finalized during design. The curb selection type will take into account snow removal operations to minimize the damage sustained to them during snow removal operations.
Most of the damage at the existing roundabouts is likely caused by snowplows. At the proposed roundabout, the circulatory roadway is significantly larger. The larger circulatory roadway will provide more mobility for snow removal operations with less potential to damage the curbs.
