DPD's Noise Abatement Program
Applying for a Noise Variance
The four types of noise variances may be granted by DPD; Temporary, Economic, Technical and Major Public Project.

Temporary Variances
Definition: The DPD Administrator may grant a temporary noise variance, not to exceed 14 days, for any activities, uses, processes, or equipment which does not annoy a substantial number of people and does not endanger public health or safety (as determined by the Administrator in accordance with applicable rules and regulations).

To apply for a temporary noise variance, you must submit a Temporary Noise Variance Application. This application includes details about the variance being requested, a list of questions that must be answered, and your key contact information. Your submittal options include:

  • Save the document to your desktop, complete the application, and send it as an email attachment to Noise@seattle.gov.
  • Print out a copy and send it by postal mail to Jeff Stalter, Noise Abatement Coordinator, City of Seattle, DPD, 700 5th Ave, P.O. Box 34019, Seattle, WA 98124-4019.

Technical Variances

A technical variance grants permission to vary from the limits of the noise control code for periods of time determined by the Administrator. This type of variance may be granted for situations where noise must unavoidably occur but there are no practical means known or available for the adequate prevention, abatement or control of the noise involved and if the Administrator concludes that the subsequent noise would not endanger public health or safety.
 
Economical Variances
An economic variance grants permission to vary from the limits of the noise control code where measures to reduce such noisy activities may be taken but because of their extent or cost must be spread over a period of time. The duration of an economic variance will be for a period not to exceed such reasonable time as is required in the view of the Administrator for the taking of the necessary measure. The Administrator must conclude that the noise would not endanger public health or safety.

 

Major Public Project Construction Variances
A major public project construction variance may be granted by the Administrator for projects with the following characteristics:
 
  • The construction project is for a public facility as defined in the Land Use Code (SMC chapter 23.84A);
  • The construction project will have a duration of at least six months; and
  • The construction project will have a substantial impact on the provision of public services (such as transportation) and public health, safety and welfare.

In deciding whether a proposal is eligible for a MPPC Variance, factors considered by the Administrator will include:

  • Director’s Rule 3-2009
  • Expected size, duration, complexity or cost of construction; and
  • Magnitude of the expected impacts on traffic and transportation; and/or
  • Degree of impact on the provision of public services during construction.
For application requirements of the Economic, Technical or Major Public Project Construction Variances, review the DPD Director’s Rule 3-2009 or contact a Noise Abatement Coordinator.
