PROJECT:
T22CM05551
3250 N Stone Ave - R-3
Duplex w/Sleeping Quarters (1st Review)

TRANSMITTAL: July 29, 2022

This site is located in the R-3 zone (UDC 4.7.12). A Duplex w/Sleeping Quarters is a permitted use in this zone (Table 4.8-2) subject to Use Specific Standard 4.9.7.B.6.

1. As the site requires 5 vehicle parking spaces and 6 are proposed per UDC Article 7.6.4.B and a Zoning Administrators determination the requirements of UDC Articles 7.6.4.B and 7.4.6 apply to this site.

2. 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 wall heights from design grade were not provided Zoning has added 6” to the heights shown on the elevations. Based on a wall height of 11.0’ the required perimeter yard setback from the duplex to the east property line is 7.34’, proposed is 7’-0”. 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.

3. Review UDC Article 6.4.3 and the lot coverage calculation example shown on the Residential Plot Plan Requirements found at: https://www.tucsonaz.gov/files/pdsd/forms/Residential_Plot_Plan_Requirements.pdf, and provide a lot coverage calculation on the plan.

4. Clarify what the provided development package sheets, DP21-0145 are for as they do not match what is shown on the plan set?
