The Old Sacramento special sign district ("OSSSD") is created pursuant to Section 15.148.940 of this title. The purpose of the sign regulations set forth in this chapter shall be to preserve and maintain the historic ambience of Old Sacramento historic district ("OSHD"), a National Historic Landmark District. These regulations will allow the OSHD to recapture the physical environment as it appeared during the third quarter of the 19th century (1849 to 1875). Because OSHD relies on its historic design theme and physical beauty to attract commerce and tourism, aesthetic considerations and authenticity are essential to the economic welfare and future economic vitality of the OSHD. Therefore, it is the intent of the city through this chapter to protect and enhance the city's character and its economic base through the provisions of appropriate and aesthetically attractive signage in the OSSSD. Detailed design guidelines for signs in the OSSSD consistent with the provisions and purposes of this chapter shall be adopted, and may be from time to time amended, by resolution of the city council.
