As provided in RCW 58.17.060, a lot that is created by short plat shall not be further divided by short platting for a period of five years, except that when the division contains less than four lots, further division may be made by short plat to create up to four total lots with the original short plat boundaries. Any further division shall be processed as a subdivision. However, any revision of the lot lines of an approved short subdivision in which the total number of lots is not increased, shall not be considered a further division and shall be approved or disapproved in the manner prescribed by Chapter 16.40 of this code.
