FROM: PDSD Zoning Review

PROJECT:
T22CM02447
8949 E Calle Kuehn - R-1
Room addition & remodel (1st Review)

TRANSMITTAL: April 5, 2022
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 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 a wall height from design grade to the top parapet was not provided for the proposed addition Zoning has added 6” to the 10’-0” shown to top of parapet to determine required 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 10’-6” the required perimeter yard setback from the proposed addition to the west property line is 7’-0”, proposed setback is 6’-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.

The following comment shall be addressed prior to submitting for the DDO:
2. Provide a residential plot plan that meets the requirements found at: https://www.tucsonaz.gov/files/pdsd/forms/Residential_Plot_Plan_Requirements.pd, to include but not limited to:
a. Provide a lol coverage calculation on the plot plan.
b. Provide a dimension from the center line of Calle Kuenh to the face of curb and a dimension from face of curb to the property line.
c. Show the 8’-0” right of way easement that runs along the north property line and provide the recordation information on the plan.
d. Indicate the zoning of the parcel and all adjacent parcels on the plan.
e. Provide the legal description on the plot plan.

3. It does not appear that the plan is drawn correctly. Based on aerial photos the western most structures appear to be much closer to the west property line than what is indicated on the plot plan. A survey may be required.

If you have any questions about this transmittal, please contact Zone1.desk@tucsonaz.gov.
