04/03/2024 Site Zoning REQUIRES RESUBMIT ZONING REVIEW TRANSMITTAL

FROM: Wyatt Berger
Lead Planner

PROJECT: TC-RES-0324-01265
1426 West Kilburn Street – O-3
New single-family residence (1st Review)

TRANSMITTAL DATE: April 3, 2024

Please resubmit revised drawings with a detailed response letter stating how all Zoning Review Section comments were addressed.

1. Remove the front and back porches from the lot coverage calculation as roofed areas, open on at least one side, which provide shelter to exterior areas, provided they are no used for utilities, maintenance, laundry, storage, or motor vehicle parking, are not included in the lot coverage calculation (UDC 6.4.3.C.1.a).

2. The lot size listed under the “lot coverage calculations” is incorrect and should be corrected to 7,740 square feet. Ensure the lot coverage calculations are revised to reflect the correct lot size.

3. Per UDC 6.4.5.C.1.a, for single-family and duplex development, the minimum required front street perimeter yard is 20 feet measured from the street property line.

The proposed front street perimeter yard is 6’-8” as measured from the building wall to the south lot line. Design Development Option (DDO) approval is required to reduce the front street perimeter yard.

4. Perimeter yards are based on a measurement from the design grade elevation to the highest point of an exterior building wall (UDC 6.4.5.B and Figure 6.4.5-A). Provide vertical dimensions from design grade to the highest point of the exterior walls or posts to determine the required setbacks.

5. Per UDC Table 6.3-3.A, the require side and rear perimeter yards are ten feet or ¾ the height of the building wall, whichever is greater. Provide setbacks measured from the construction to the east and north lot lines.

6. The original single-family residence appears to have been demolished in 2022 without prior zoning approval. According to the Pima County Assessor’s Office, the effective construction date for this building was 1952.

Buildings, portions of buildings, or structures that are 50 years of age or older must be architecturally documented prior to demolition. Documentation shall be reviewed and approved by the City Historic Preservation Office prior to zoning approval of this permit.
