| 03/21/2023 | Site Zoning | REQUIRES RESUBMIT | FROM: PDSD Zoning Review PROJECT: TC-RES-0123-02330 130 N Cherry Ave. – R-2 SFR Addition & Convert Existing SFR to ADU (1st Review) TRANSMITTAL DATE: March 21, 2023 Please resubmit revised drawings and any redlined plans along with a detailed response letter, which states how all Zoning Review Section comments were addressed. This site is located in the R-2 zone (UDC 4.7.9). A single-family residence (SFR) with an accessory dwelling unit (AUD is a permitted use in this zone (Table 4.8-2). See Use-Specific Standards 4.9.7.B.6, .8, .9, & .10 & 6.6.3. 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. 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. As dimensions from design grade to the highest point the exterior wall Zoning has added an addition 6” to the heights shown on the building elevations to determine perimeter yard setback requirements. Based on a wall height of 11’-0” the required perimeter yard setback to the north and east property line is 7’-4”. As the setback lines do not represent the correct perimeter yard setback and no setback dimensions were provided Zoning cannot determine if the setbacks are met. A Design Development Option may be required to reduce the perimeter yard setbacks. 2. Per 6.6.3.B.4 On sites where the principal structure is one story, accessory dwelling units shall not exceed 12 feet in height. Clearly demonstrate that the proposed ADU does not exceed the allowed 12’-0” height. Review UDC Article 6.4.4.A and provide building height for the ADU. 3. The Lot Coverage calculation is not correct. Per UDC Article 6.4.3.C.1.a Roofed areas, patios, open on at least one side and not included in the lot coverage.
