The purpose of the historic downtown overlay is to recognize the historical character of site planning, street grid, architecture and building scale of structures in East Stanwood and West Stanwood commercial nodes. Within the historic overlay the city will allow flexible interpretations of standards to encourage re-investment in, re-use and maintenance of structures that display historic period architectural character and scale. The architectural styles representative of commercial and residential buildings that existed from 1890 through the 1920s are to be maintained. (Ord. 1276 § 3, 2010).
