The bill proposes the introduction of a new special license plate called "Nautical Northwest," which will be available for an initial fee of $40.00 and a renewal fee of $30.00. This plate will be added to the existing special license plates under RCW 46.17.220. The bill amends existing laws, specifically RCW 46.18.200 and RCW 46.68.420, to include the Nautical Northwest plate and its associated fees. The primary purpose of this plate is to support the historic resources of Whidbey Island's maritime communities, with proceeds from the fees directed towards this cause.

Additionally, the bill outlines eligibility criteria for cities to receive construction funds for public tennis facilities, prioritizing the most populous eligible city without existing facilities that have at least four indoor tennis courts. Maintenance funds will be available to the first city that utilizes construction funds as specified. The bill also mandates that at least 90 percent of funds from the Seattle Seahawks and Seattle Mariners accounts be allocated for specific programs, such as fellowships and youth services. A new section defining "Nautical Northwest license plates" is introduced, and the act is set to take effect on November 1, 2025.
