04/26/2024 Site Zoning REQUIRES RESUBMIT ZONING REVIEW TRANSMITTAL

FROM: Wyatt Berger
Lead Planner

PROJECT: TC-RES-0324-01705
5950 South 6th Avenue – R-2
New duplex (1st Review)

TRANSMITTAL DATE: April 26, 2024

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

1. Submit a site plan that shows only the proposed duplex and applicable site improvements. Do not depict any other buildings or structures not within the scope of work of TC-RES-0324-01705.

2. Include a lot coverage calculation of the site plan. Lot coverage includes the area of the lot covered by buildings, outdoor storage areas, and vehicular use areas, whether paved or unpaved. Lot coverage shall not exceed 70% (UDC Table 6.3-2.A).

3. The zoning classification provided on Sheet C1 under “project data” is incorrect and should be revised to R-2.

4. 6th Avenue is designated as a collector on the Major Streets and Routes Plan with a future right-of-way width of 100 feet and a half right-of-way width of 50 feet. Provide the future right-of-way line on the site plan and provide a setback dimension from the future right-of-way line to the proposed building. The required front street perimeter yard is 20 feet measured from the future right-of-way line (UDC 6.4.5.C.1.a).

5. Per UDC 7.6.4.B and a previous Zoning Administrator’s determination, the requirements of UDC 7.4.6 and 7.6.4 apply to all developments that provide five or more motor vehicle parking spaces. In April of 2023, the Mayor and Council adopted a code amendment that only requires one motor vehicle parking space per dwelling unit. Zoning staff recommends providing four or fewer motor vehicle parking spaces to avoid the requirement to comply with UDC 7.4.6 and UDC 7.6.4.
