This site is located in the R-1 zone (UDC 4.7.1). A single-family residence (SFR) is a permitted use in this zone (Table 4.8-2). See Use-Specific Standards 4.9.7.B.5 - 9. 10. Perimeter yard setbacks are based on a measurement from design grade to the highest point of the exterior wall UDC Article 6.4.5.B & Figure 6.4.5-A. As height dimensions from design grade were not provided, 6” has been added to the heights provided on the elevations to determine perimeter yard setbacks. The minimum setback is the greater of six (6) feet, or two-thirds (2/3) the height of the structure’s wall facing each interior property line (Table 6.3-2.A). 1. Based on a wall height of 12’-2” the required perimeter yard setback from the proposed garage to the east property line is 8’-2”, proposed setback is 1’-7” A Design Development Option (DDO) must be submitted and approved to reduce the required setback, DDO application and requirements can be found at: https://www.tucsonaz.gov/files/pdsd/forms/DDO_for_Setback_and_Height_UDC_8.11.20.pdf. A DDO is a separate submittal from the building plan and shall be submitted at: https://www.tucsonaz.gov/pdsd-filedrop, using the Submission Type “Zoning Administration”. If you have questions about the DDO application or process please contact Mark Castro at Mark.Castro@tucsonaz.gov. The following comments need to be addressed: 2. The plot plan shall be drawn at an engineering scale, i.e. 1” = 10’, 1” = 20’ etc. 3. Provide a dimension from the centerline of Rolling Ridge St to the face of curb and from the face of curb to the north property line. 4. As the proposed ‘HOME THEATER” qualifies as a bedroom, see UDC Article 11.4.3 definition of Bedroom, provide a full floor plan of the existing SFR so that vehicle parking space requirements can be verified, see UDC Article 4.9.7.B.7. If you have any questions about this transmittal, please contact Zone1.desk@tucsonaz.gov. |
