Early submission of third party plans is encouraged. All submissions and supporting materials should be mailed or delivered to the commission's office (not to a commissioner) in Olympia, or they may be presented to commission staff at any public hearing held by the commission. Submissions may be electronically mailed to the commission's address identified in WAC 417-01-125, or made directly to the commission through any redistricting mapping tool on its web site. The date of the electronically mailed submission shall be the date the delivered materials are received by the commission. The submission envelope, cover letter and all other submission materials should be clearly marked: "Redistricting Plan Submission." The person or organization submitting the plan bears the responsibility and accepts the risk to ensure timely delivery of the plan to the commission. The commission has no responsibility to review untimely or improperly submitted plans.
