Site Engineering Comments:
1. This site resides within a Fema zone X regulatory floodplain and will require the submission and approval of a floodplain use (FPU) permit. The FPU permit is a separate permit that can be submitted within the "sub-records" tab of this associated building permit through TDC online.
2. The FPU permit submission requires submission of a cost estimate for all work performed on the existing residence, the detached carport and fence can be excluded from the estimate. A cost estimate of both materials and labor will be required from the contractor responsible for the project. Break down the total cost into separate lines, separating labor, materials/equipment, and warranties/fees associated with the project. Ensure to have company/contractor letterhead on the document for proper documentation. This cost estimate will be used for substantial improvement calculations. If the project is done as an Owner-Builder, then an OB affidavit is required.
3. Additionally, provide a cost estimate for the installed solar system as this will contribute to the substantial improvement calculations too.
4. Final Site Engineering approval for permit TC-RES-1225-05991 requires review and approval of associated submitted FPU permit.
5. Regarding the fence, flood spacing minimum of 6 inches from natural grade will be required. Flood spacing shall extend the entire length of fence, excluding support members, along the bottom to allow water to flow unobstructed. Please change detail C on A2 of plan set to reflect this.

12/30/2025 Residential Zoning REQUIRES RESUBMIT PDSD TRANSMITTAL

FROM: Roxanne Johnston, Planner

PROJECT: TC-RES-1225-05991
6441 E Duke Dr., Tucson, AZ 85710
New Carport, Convert Exist. Carport & 6’ Fencing (1st Review)

TRANSMITTAL DATE: 12/30/2025

This site is located within 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.

RESUBMITTAL OF THE FOLLOWING IS REQUIRED: Correct plans, as noted in the comments below, along with a response letter indicating how all Site Zoning comments were addressed.


1. What is shown as a temporary shed on Sheet A0 has no permit and sits within the rear and west side perimeter setbacks. For the purposes of determining the perimeter setbacks, show the distance from the shed to the north and west property lines and provide the height of the shed (see Comment 2 on how height is determined). If the shed is not relocated outside of the perimeter setbacks, it will require approval of a DDO since the alley is 20’-wide.
Without either relocating the shed out of the setbacks, or the DDO approval, Site Zoning is unable to approve the site plan. To submit an application for a DDO, please use the link and follow the instructions below:

www.tucsonaz.gov/files/sharedassets/public/v/1/pdsd/documents/boards-committees commissions/drb/012425/ddo-24-81-application-packet.pdf Submit a DDO application under the Zoning Modification sub-record that you will create - for instructions on how to apply for a sub-record, visit the following link: https://www.tucsonaz.gov/files/sharedassets/public/v/1/pdsd/documents/tdc-faq/new-pdfs/sub-records_071425.pdf

For questions regarding the DDO process, please contact Georgia Pennington at georgia.pennington@tucsonaz.gov


2. UDC 6.4.4.A explains that building height is the vertical distance measured from the design grade elevation to the highest point of a flat roof; to the deck line of a mansard roof; or to the middle (between the eave and ridge) of the highest gable of a pitched or hipped roof. Sheet A-3 has not calculated height based on these criteria. Please revise Sheet A-3 to meet the criteria listed in UDC 6.4.4.A and show the correct elevations for the proposed carport and the existing carport to be turned into a living space – from design grade to the top of the wall where it meets the roof.

3. Sheet A0 notes a rusted metal fence to match existing 6’-0” max ht. Please note on the site plan the linear feet and show a diagram of how the height of the fence is measured.


4. Additional comments may be forthcoming depending on responses to zoning review comments and plans submitted for the next review.
