Construction / Work Areas

When development or redevelopment occurs, parts of the right-of-way are often used for construction activities including loading and unloading of construction materials, construction vehicle access, scaffolding, replacement or repair of sidewalks and roads, and construction offices. These projects must be issued a permit for all work within the right-of-way. Street Use Permits are granted upon approval of a Traffic Management Plan. As described in the Right-of-Way Improvements Manual, Traffic Management Plans must meet the following principles:

  • Work areas are safe and congestion is minimized;
  • Motorized and non motorized traffic is warned, controlled, and protected; and
  • All traffic is expedited through the work zone to the extent possible.

Permitting construction and work zones in the right-of-way allows SDOT to evaluate the duration and type of closure. This information can help minimize impacts and control long stretches of closures. In addition, mitigation for the closures can be addressed. Temporary pedestrian walkways, lane closures for pedestrian access, adequate signing for temporary closures with alternative route information, and temporary lighting are elements that can maintain pedestrian access when closures are approved.
