FROM: PDSD Zoning Review

PROJECT: T21CM02838
339 N Highland Ave
New Guest House (1st Review)

TRANSMITTAL DATE: April 19, 2021

This site is located in the R-2 zone (UDC 4.7.9). A single-family residence is a permitted use in this zone (Table 4.8-2) subject to Use Specific Standards 4.9.7.B.6, .9, & .10

1. Address 339 N Highland Ave does not match the parcel number, 124-08-1810, shown on the plan. The parcel number for 339 N Highland Ave is 124-08-0810.

2. The parcel dimensions shown on the plan do not match the dimensions for parcel 124-08-0810. Per the Assessor’s record map the north/south dimension is 40’ and the east/west is 75’. These dimensions also reflect the legal description DRAKES S40' LOTS 13 14 & 15 BLK 16

3. Per UDC TABLE 6.3-2.A: DIMENSIONAL STANDARDS FOR THE R-1, R-2, R-3, MH-1, & MH-2 ZONES, R-2 ZONE, the minimum lot size in the R-2 Zoning for a parcel with two (2) dwelling units is 5,808 sq. ft. Based on a lot that is 40, x 75’ this parcel is only 3,000 sq. ft. and is considered non-conforming. A Board of Adjustment for Variance or a rezoning is required to allow the 2nd dwelling unit.

Additional comments maybe forth coming once the lot dimension issues area addressed.
