2.9. ARCHITECTURAL CHARACTER REGULATIONS This section contains regulations which aim to create architectural character in new projects that is compatible with the established patterns in the various parts of Downtown, as well as with the expressed aesthetic preferences of the community. Considering a study of historic resources and the desires of the residents of Redwood City as expressed in a large Community Character Workshop as described in detail in Appendix 1: Historic Resources Preservation Strategy, Downtown has been broken down into six architectural “Character Zones.” Within these zones, six different “Character Types” are allowed in varying combinations depending on the nature of the zone and the preferences of the community.
