COMMENTS: the following comments are relative to an application for a Design Development Option (DDO) (UDC 3.11.1).

This site is located in the O-3 zone (UDC 4.7.15). A single-family residence is a permitted use in this zone (Table 4.8-3).

The minimum setback is the greater of ten (10) feet, or three-quarters (3/4) the height of the structure’s wall facing each interior property line (Table 6.3-3.A).
1. Based on a wall height of 12’-2” the required perimeter yard setback from the proposed addition to the north property line is 10’-0” proposed is 5’-10”. A Design Development Options must be submitted and approved to reduce the required perimeter yard 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 prior to submitting for the DDO:

2. The lot coverage calculation is not correct. Per UDC Article 6.4.3.B.3.b all vehicle use areas, whether improved or unimproved, are included, see the example shown on the Residential Plot Plan Requirements found at: https://www.tucsonaz.gov/files/pdsd/forms/Residential_Plot_Plan_Requirements.pdf. This would include the entire 24’ ingress/engress easement along the west end of the property.

3. The parcel shape and dimensions are not correct. Review final plat “A Mountain Vistas Lots 1 Thru 12 found at: https://www.tucsonaz.gov/apps/maps-and-records/subdivisions/details/5826, and provide the correct shape and dimensions on the plot plan.

4. There are several easements shown on the final plat that need to be shown on this plan Show the 24’ ingress/engress & utility easement along the west side of the property and a utility easement along the east side of the property.

5. Remove the reference to “ALLEY” from the plan as this is a 24’ ingress/engress easement.

If you have any questions about this transmittal, please contact Elisa Hamblin at Elisa.Hamblin@tucsonaz.gov.
