Concerning the administration of plats.

HB 1818 updates Washington's land subdivision laws, which haven't been revised since 1969, to create a uniform process for dividing land. It eliminates outdated distinctions between "short plats" and "subdivisions" by merging their requirements, as current rules have become identical over time. The bill amends multiple statutes to streamline the approval process for land division maps, ensuring local governments use consistent standards for preliminary and final plats. This primarily affects cities, towns, and counties that review and approve land development projects.
