2. In the absence of a set of standards, it is more likely than not that this character would in large part be lost.
3. The guidelines in this chapter are intended to provide meaningful guidance to applicants, design professionals, and public officials charged with administering this chapter without dictating a certain architectural style.

17.58.030 Purpose

1. protect the distinctive neighborhood character that is generally found throughout the district
2. allow redevelopment, infill development, maintenance, and remodeling of existing residences consistent with the established standards
