B. Stepbacks Buildings of 8 or more stories are required to place a stepback above the 3rd floor but below the 8th floor. 1. The stepback is only required on building faces adjoining the public street. 2. The depth of a required stepback may be reduced by 5 feet if the cornice line of the stepback matches the cornice line of an adjacent building. C. Administrative Alternate Findings The Planning and Development Officer may in accordance with Sec. 10.2.17. approve an alternate building massing standard, subject to all of the following findings: 1. The approved alternate meets the intent of the building massing regulations. 2. The approved alternate conforms with the Comprehensive Plan and adopted City plans. 3.
