| 05/27/2022 | STEVE SHIELDS | ZONING | REVIEW | Reqs Change | ZONING REVIEW TRANSMITTAL FROM: PDSD Zoning Review PROJECT: T22CM03776 5608 E Hawthorne St - R-1 New ADU (1st Review) TRANSMITTAL: May 27, 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 4.7.8). A single-family residence is a permitted use in this zone (Table 4.8-2) subject to Use Specific Standards 4.9.7.B.5 – 9. 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 were provided from finished floor, not design grade, Zoning added 6” to the dimensions provided to determine perimeter yard setback requirements 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 less than 9’-0” the required perimeter yard setback from the proposed ADU to the east property line is 6’-0”, proposed setback to the east property line is 5’-8”. 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. Additional comments that need to be addressed prior to submitting the DDO: 2. Demonstrate on the plan that the requirements of UDC Article 6.6.3.B.3 are met. UDC Article 6.6.3.B.3 states “If the accessory dwelling unit is built as a new structure it must be developed with a high albedo level (>60 SRI) or other cool roof technology per the ICC Green Construction Code.” 3. The north/south property line dimension, 165.00, is not correct and should be 135’. 4. Based on current aerial photos there are a couple of detached accessory structures located near the southwest corner of the site. Show these structures on the plan and include them in the lot coverage calculation. The structure closest to the south property line appears some time after 2018 and Zoning was not able to find approved permit documents for this structure. Either provide approved permit documents for this structure or include it in this permit. It does not appear that this structure meets perimeter yard setbacks and at a minimum will require a neighbor setback waiver. To secure this neighbor setback waiver the following statement must be provided on the plot plan and be signed and dated by the adjacent property owner(s): My Name is____________________ and I am the owner of the property located at_______________________. I have reviewed the site plan and I have no objection to structure being located or constructed________ feet from the property line as depicted on the site plan. Signature: _____________________________ Date: _________________________________ If you have any questions about this transmittal, please contact Zone1.desk@tucsonaz.gov |
