SDOT Street Use: Construction Management Plan

During your building permit process, you may need to develop and submit a Construction Management Plan (CMP) which addresses some of the hows of demolition, if needed, and construction coordination.  The CMP is a document that outlines plans for elements such as notification, noise mitigation, vehicle and material movement, and right-of-way use.  The CMP must include all elements listed in the template below, including Haul Route narrative and map.  This is necessary to ensure that the construction impacts to the public are appropriately mitigated. 

The CMP clarifies how demolition and construction impacts to the public will be managed over the course of your project.  It allows the City to identify and mitigate potential concerns before work begins.  A CMP also serves as a collaborative tool to lessen the impacts your project may have on surrounding environs and people.

For instance, we want to know:

  • How much material will be transported by truck and what route shall the truck take to and from the project site?
  • How will heavy equipment get to your project site?
  • How will a crane impact the public right-of-way?
  • What hours does your construction team plan to work?
  • Will excessive noise impact adjacent buildings?

CMP and Haul Route documents shall be submitted to the Seattle Department of Transportation (SDOT) via as soon as there is enough information to determine how the project will be built.  SDOT prefers that the customer submit the CMP three to six months prior to beginning construction.  A CMP shall always be submitted prior to a Traffic Control Plan (TCP) as it is the high-level snapshot to ensure impacts are appropriately defined and mitigated.  To further clarify, a CMP is a requirement prior to Seattle Department of Construction and Inspections (SDCI) issuance of Excavation/Shoring or Construction permits and prior to submitting for a SDOT Street Use permit.

When is a Construction Management Plan required?
CMP requirements originate through SDCI when the State Environmental Policy Act (SEPA) thresholds are triggered or as mitigation for project-related construction impacts as a condition of a Master Use Permit (MUP). The requirement for a CMP will be embedded as a condition in the projects MUP decision.

What is the CMP intended to do?
A CMP is intended to mitigate construction-related impacts including, but not limited to: public accessibility, business access, traffic, parking, and noise.  The CMP is also used to identify the timing and methods of communication from the contractor to communities affected by demolition and/or construction.  Seattle Municipal Code (SMC) 25.05.675B Construction Impacts defines the policy background and policies that describe the reason for a CMP.

The CMP requirements allow SDOT Street Use to collaborate with the SDCI in streamlining the permit application process to engage contractors earlier for coordination and planning.  You will not receive a separate SDOT permit number for the CMP review as it is a condition of the MUP decision.

Our goal is to make permitting more efficient while also facilitating traffic flow, maximizing mobility for people walking and biking, and ensuring access to adjacent buildings.

When and how do I submit a CMP?
A CMP, with the accompanying Haul Route narrative and maps, should be submitted a minimum of three to six months prior to beginning work.  You are required to have an approved CMP prior to the issuance of a SDCI Excavation/Shoring permit or a Construction permit and a SDOT Street Use permit.  You will be notified of the requirement to submit a CMP when you receive your MUP decision from SDCI, it will be a condition embedded in the MUP decision.

CMPs should be submitted electronically to SDOT via Please submit the CMP and accompanying Haul Route in two separate documents within the same email.  Please list your project address, SDCI land use and construction numbers, and the word CMP in the subject header line of your email and the two required documents. 

What is the CMP review process?
The review period for CMPs is two weeks.  Review comments will be provided to you at the end of this period via email in the form of a comment spreadsheet to the person who submitted it. If the CMP review team has comments, you are required to revise your CMP as directed via the comment spreadsheet and share any changes with your team.  The revised CMP does not have to be re-submitted to SDOT, unless requested.  If the CMP review team decides that there are too many unknowns about the project, we will ask for more details via the comment spreadsheet and the CMP will need to be resubmitted for a subsequent two-week review period.

If the Haul Route document contains comments, it is expected that you will make both narrative and map edits and re-send to SDOT for approval. 

If a CMP is required as a condition of your MUP, you may not receive your SDCI permits until your CMP has been approved.  You will know when your CMP is approved via email from SDOT.  This email should then be forwarded to your projects assigned SDCI zoning reviewer and land use planner to satisfy your MUP condition.
