The city’s approach to planning for subdivisions requires a four-step process that gives the highest priority to identification and conservation of existing natural site features. This process reverses the conventional site planning approach, which typically begins by laying out the streets, lot lines and building footprints. Instead of first identifying the areas to be cleared for development, the design process begins by analyzing on-site resources and the site’s relationship to surrounding properties, in order to identify what resources are most worthy of preservation and what areas can best accommodate development.

This design process is required for all residential subdivisions. The process is further defined in BIMC 2.16.125.D; it consists of four steps: (A) delineate natural area; (B) locate homesites and community space; (C) define access; and (D) draw lot lines. (Ord. 2019-03 § 5 (Exh. A), 2019)
