(1) Regulations for subdivision approvals and dedications, must require that the county or city make written findings that "appropriate provisions" have been made for the public health, safety, and general welfare, including open spaces, drainage ways, streets or roads, alleys, other public ways, transit stops, potable water supplies, sanitary wastes, parks and recreation, playgrounds, schools and school grounds, and all other relevant factors, including sidewalks and other planning features that assure safe walking conditions for students who walk to and from school; and that the public use and interest will be served by the platting of such subdivision and dedication.

(2) All cities, towns, and counties shall include in their short plat regulations procedures for unit lot subdivisions allowing division of a parent lot into separately owned unit lots. Portions of the parent lot not subdivided for individual unit lots shall be owned in common by the owners of the individual unit lots, or by a homeowners' association comprised of the owners of the individual unit lots.

(3) Regulations for short plat and short subdivision approvals may require written findings for "appropriate provisions" that are different requirements than those governing the approval of preliminary and final plats of subdivisions. However, counties and cities must include in their short plat regulations and procedures provisions for considering sidewalks and other planning features that assure safe walking conditions for students who walk to and from school.

(4) Regulations for subdivision approvals may require that the county or city make additional findings related to the public health, safety and general welfare to the specific listing above, such as protection of critical areas, conservation of natural resource lands, and affordable housing for all economic segments of the population.

(5) In drafting development regulations, "appropriate provisions" should be defined in a manner consistent with the requirements of other applicable laws and with any level of service standards or planning objectives established by the county or city for the facilities involved. The definition of "appropriate provisions" could also cover the timing within which the facilities involved should be available for use, requiring, for example, that such timing be consistent with the definition of "concurrency" in this chapter. See WAC 365-196-210.
