2.11 Deviation Request Process for Street Right-of-Way Improvements

The Deviation Request Process defined in this section applies to deviations from the design criteria presented in this Manual, and does not apply to or replace, any other deviation, variance or exception process required for the City of Seattle permits or approvals or those of other agencies. For instance, requests to modify or waive a Land Use Code requirement for street improvements must be submitted to DPD (see DPD CAM 205 for instructions to apply for Street and Alley Improvement Exceptions).  The design criteria presented in this Manual have been developed to assure that Seattle’s street rights-of-way are designed in such a manner as to protect the health, safety, and welfare of the public and to minimize post-construction maintenance and repair costs.

An applicant can request a deviation from the design criteria in this Manual for a street right-of-way improvement project by following the process defined in this section. In the case of a deviation request, the Seattle Department of Transportation (SDOT) will require the applicant to follow the procedure defined in Chapter 2.11.1 Deviation Request Submittal Process. The final decision on whether a deviation request is granted lies with SDOT.

2.11.1 Deviation Request Submittal Process
  1. Design guidance meetings: The applicant must obtain approval through a 60% Complete SIP Design Guidance meeting.  Design guidance meetings at the 0-30%+ level are optional and can be held to share contact information and discuss information relative to proposed street right-of-way improvements, including potential deviations and the necessary information that SDOT will require to evaluate the deviation request prior the 60% complete submittal. Refer to CAM 2211 for more information regarding the Design Guidance process.
  2. Deviation request submittal: If the applicant chooses to apply for a deviation, he or she must submit the following in addition to the requirements for a 60% Complete SIP Design Guidance Meeting:
    • A completed Deviation Request Form. Depending on the nature of the improvement, SDOT may require the deviation request to be signed and sealed by a professional engineer.
    • Description of how proposed work is consistent with the Comprehensive Plan, Transportation Strategic Plan, as well as any subarea transportation plans or neighborhood plans relevant to the area.
    • Engineering justification for the deviation proposal. The justification should describe the impacts of meeting the standard and why the deviation is the preferred alternative.
    • Information on existing and predicted vehicular and pedestrian traffic volumes, when changes are expected as a result of the project.
    • Any additional information defined in the previous Design Guidance meetings that SDOT determine necessary to evaluate the deviation request.

      The permit reviewer will screen the submittal package to determine if it meets the minimum submittal requirements for a 60% Complete SIP Design Guidance Meeting and provide the screening outcome within 3 business days.
  3. Deviation request coordination and review: When a deviation request is submitted, SDOT’s Street Use staff will consult with appropriate staff within SDOT and other departments that will be impacted by the deviation. If a 60% Complete SIP Design Guidance Meeting is not needed to process the deviation request, SDOT will typically process the request and notify the applicant if the request has been accepted or rejected within one week of the submittal. If City staff require additional information to process the request, the SDOT reviewer will alert the applicant that a 60% Complete Design Guidance meeting is required.
Permit submittal: Following acceptance or rejection of the deviation request, the applicant may submit 90% Complete SIP plans for formal review.
