PROJECT:
T20CM04952
1664 E CALLE GRANDIOSA
BEDROOM ADDITION

TRANSMITTAL: 8/5/20
COMMENTS: the following comments are relative to an application for a Design Development Option (DDO) (UDC 3.11.1).

This site is located in the R-2 zone (UDC 4.7.9). A single-family residence (SFR) is a permitted use in this zone (Table 4.8-2). See Use-Specific Standards 4.9.7.B.5 - 9.

The minimum setback is the greater of ten (10) feet, or three-quarters (3/4) the height of the structure’s wall facing each interior property line (Table 6.3-2.A). The setbacks are such because the subject property has a residential use and abuts a non-residential zone, P-I.

Applicant is proposing to construct a bedroom addition attached to the rear of the home. The plan indicates a wall height of 8’ and 6” is added to design grade. With this 8’6” wall height a 10’ setback is required to the south property line. Applicant is proposing a 8’8” setback to the south property line.

Additionally, although the addition is in line with the existing setback for the home to the east property line, the required setback is 6’8”. The plans show a top height of the bedroom addition at 9’4”, with an additional 6” added for design grade. Therefore, a top height of 10’ is used. This requires a 6’8” setback to the east property line. A 3’8” setback is proposed to the east property line. Applicant may provide documentation showing subdivision developed under Residential Cluster Project standards, allowing for reduced setbacks and DDO will not be required for east setback.

DDO is required.
