Applicants are required to provide public notification when applying for actions or permit types described in chapter 20.20 of the King County Code (KCC).

The State Environmental Policy Act of 1972 (SEPA) also requires public notification of environmental threshold determinations (TD) for these applications and other actions. For more information about SEPA requirements, see the SEPA Environmental Checklist Handout, or visit the Washington State Department of Ecology's SEPA Environmental Review web pages for notification information and related documents.

Any interested person may submit written comments or may appeal the above determination(s) according to KCC Title 20. Written comments may be made at anytime and should be addressed the King County Department of Permitting and Environmental Review(DPER). However, comments on the scope of any project or required environmental impact statement need to be submitted (in writing only) for twenty-one (21) days following the determination posting date in order to be officially accepted as part of the project's record.

Appeals to any threshold determination or decision must be received in the DPER at the time stated in each individual determination or decision. All appeals must be accompanied by a nonrefundable $250 filing fee.

The appeal must state the perceived errors in the threshold determination, specific reasons why the determination should be reversed or modified, the harm the appellant will suffer if the threshold determination remains unchanged, and the desired outcome of the appeal.  If the appellant is a group, the harm to any one or more members must be stated. Failure to meet these requirements may result in dismissal of the appeal.

Written comments or appeals should be addressed or delivered to:

King County Department of Permitting
35030 SE Douglas Street, Suite 210
Snoqualmie, WA 98065-9266

Any person interested in receiving information related to the environmental reviews of development proposals, such as notice information of SEPA appeals, should contact the DPER at 206-296-6600 and ask to be made a 'Party of Record.' All requests need to include the file name and file number of the proposal, along with the name and complete mailing address of the requester. Please reference the file number(s) when corresponding.
