Design Review
Address: 1521 Willow Avenue
Item No. 11
Design Review Study
Meeting Date: April 28, 2014
Request: Application for Design Review for first and second story additions to an existing single-family
dwelling.
Applicant and Designer: Mark Robertson
Property Owners: Robert and Jessica Lawson
General Plan: Low Density Residential
APN: 028-141-240
Lot Area: 9,385 SF
Zoning: R-1
Project Description: The existing house is two stories with an attached carport at the front of the dwelling.
There is also a detached accessory structure at the rear of the lot that is used for storage. The applicant is
proposing first and second floor additions to the main dwelling. The existing structures on the site total 3,241 SF
(0.35) of floor area. With the additions, the total FAR on the lot will increase to 4,098 SF (0.44 FAR) where 4,103
(0.44 FAR) is the maximum allowed. The proposed project is within 1% of the maximum allowed FAR.
The proposed additions to the existing house will be at the front and the left side of the existing first floor and to
the existing second floor. There is an existing protected-size oak tree at the rear, right side of the property,
between the house and the detached storage structure. The applicant is not proposing to remove this tree and
the Parks Supervisor notes in his February 18, 2014 memo that any construction within the drip line of the tree
requires that a Tree Protection Plan be in place prior to the start of demolition or construction on site.
There are five bedrooms in the existing dwelling and with the proposed additions, the number of potential
bedrooms will not be increased. Three parking spaces, two of which must be covered, are required on site. The
existing attached carport provides two covered parking spaces that are non-conforming in width (8'-10" x 20' for
each space where 9' x 20' is required for an existing covered parking space). The applicant is not proposing any
changes to the covered carport. All other Zoning Code requirements have been met.
The applicant is requesting the following applications:
• Design Review for first and second story additions to an existing single family (C.S. 25.57.010 (a) (2).
