After entering information for the first submission, it will ask if you have a second one (and, after that, if you have a third). This form will accept up to three submissions. If you wish to submit more than three designs, package the information as a PDF and send it to nicolas.welch@seattle.gov.Submissions on OpenGov ask for an employee identification number (EIN). Individuals submitting a design who do not have an EIN should enter their SSN in that field.For technical issues with this form, email nicolas.welch@seattle.gov.
