COMMENTS: The following comments are for the purpose of applying for a variance before the Board of Adjustment (UDC Section 3.10.1).

COMMENTS: the following comments are relative to an application for a Board of Adjustment Variance (UDC 3.11.1).

This site is located in the C-1 zone (UDC 4.7.20). 2 single family dwellings are permitted use in this zone (UDC Table 4.8-4)

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 10’ feet, or three quarters (3/4) the height of the structure’s wall facing each interior property line (TABLE 6.3-4.A).
As wall heights were provided from finished floor not design grade Zoning has added 6” to the provided heights to determine required perimeter yard setbacks.
1. This comment was not addressed. Based on a wall height of 14’-0” the required perimeter yard setback from the proposed ADU to the south property line is 10’-6”, proposed setback is 0’-6”.
