In those instances where it is determined that building or use addresses necessitate the designation of private streets, courts or ways, such proposed designations shall be reviewed by the Traffic Engineer, City Engineer, Code Enforcement Director, and Metropolitan Planning Director for consistency and uniformity with the official street name policies and system of the City. Under unusual or unique conditions such as historical, commemorative or honorary, the identification and designation of such streets may deviate from the consistency and uniformity of the official system of the City. Building addresses shall be determined by a numerical system based on the block hundred number and quadrant designation. (Code 1981 § 40-233. Code 1995 § 130-496.)
