COMMITTEE REPORT
MEETING DATE: 01/26/2022 ITEM NO: 6
DATE: January 21, 2022
TO: Historic Preservation Committee
FROM: Joel Paulson, Community Development Director
SUBJECT: Preliminary Review for Construction of Exterior Alterations and a Second-
Story Addition Greater than 100 Square Feet to an Existing Single-Family
Residence on Property Zoned R-1:8 Located at 50 Hernandez Avenue.
APN 510-20-003 PROPERTY OWNER: Richard Archuleta and Chrissy Klander.
APPLICANT: Jay Plett, Architect. PROJECT PLANNER: Sean Mullin
RECOMMENDATION:
Consider a preliminary review of a request for construction of exterior alterations and a second-
story addition greater than 100 square feet to an existing single-family residence on property
zoned R-1:8 located at 50 Hernandez Avenue.
PROPERTY DETAILS:
1. Date primary structure was built: 1903 (effective year built 1920) per County Assessor’s
Database
2. Town of Los Gatos Historic Status Code: Unknown
3. Does property have an LHP Overlay? No
4. Is structure in a historic district? No
5. If yes, is it a contributor? N/A
6. Findings required? No
7. Considerations required? Yes
DISCUSSION:
The Santa Clara County Assessor’s Database lists a construction date of 1903 for the existing
residence, with an effective year build date of 1920, indicating substantial construction
occurred to the residence. The 1990 Anne Bloomfield Survey provides some information on the
subject residence but shows some uncertainty of its construction date (Attachment 1). Some of
the Bloomfield materials seem to corroborate the County Assessor’s date of 1903 and include

N:\DEV\HISTORIC PRESERVATION\HPC Reports and Attachments\2022\01-26-22\Item 06 - 50 Hernandez Ave\Staff Report.docx
DISCUSSION (continued):
some notations that the residence was a rental house of the larger Seeley property. The
Sanborn Fire Insurance maps show the residence on the subject property in 1904 through 1956,
showing some moderate changes occurring to the building footprint through that period
(Attachment 2). Lastly, the applicant has submitted blueprints dated 1947 showing a remodel
and a kitchen addition on the upper level (Attachment 3).
The existing Colonial Revival two-story residence (Attachment 4) is located on the north side of
Hernandez Avenue at the intersection with Palm Avenue. The applicant is requesting
preliminary review of a proposal to construct additions to the rear of the existing upper and
lower floors, and improvements to the basement level to create habitable space (Attachment
6). The additions to the upper floor would be constructed to the rear of the master bedroom
and living room. Additions at the lower level would be made to the kitchen and family rooms.
A new terrace would project off the rear of the residence, partially covered by a roof supported
by columns to match the existing columns on the residence. The area below the lower level
would be excavated and improved to create a habitable basement space, daylighting to the rear
of the residence. While some of the existing windows would remain, the proposal includes new
windows on each level, including reconfiguration and replacement of windows on the street-
facing façade. All new materials are proposed to match existing, except for a new standing
seam metal roof above the new terrace at the rear of the residence.
CONCLUSION:
The applicant is seeking preliminary feedback from the Committee on the proposal. Should the
Committee find merit in the request, the project would require approval of a Minor Residential
Development application and would return to the Committee under this application for a
recommendation to the Community Development Director.
CONSIDERATIONS:
A. Considerations
Sec. 29.80.290. Standards for review.
In evaluating applications, the deciding body shall consider the architectural style, design,
arrangement, texture, materials and color, and any other pertinent factors. Applications
shall not be granted unless:
For pre-1941 structures, the proposed work will neither adversely affect the exterior
architectural characteristics or other features of the property which is the subject of
the application.

Residential Design Guidelines 33
Town of Los Gatos
BUILDING DESIGN3
3.8.3 Use traditional detailing
•Treat openings in walls as though they were constructed of
the traditional material for the style. For example, be sure to
provide substantial wall space above arches in stucco and
stone walls. Traditionally, wall space above the arch would
have been necessary to structurally span the opening, and
to make the space too small is inconsistent with the archi-
tectural style.
•Openings in walls faced with stone, real or synthetic, should
have defined lintels above the opening except in Mission or
Spanish Eclectic styles. Lintels may be stone, brick or wood
as suits the style of the house.
•Treat synthetic materials as though they were authentic.
For example, select synthetic stone patterns that place the
individual stones in a horizontal plane as they would have
been in a load bearing masonry wall.
•Select roof materials that are consistent with the traditional
architectural style (e.g., avoid concrete roof tiles on a Crafts-
man Style house.)
3.8.4 Materials changes
•Make materials and color changes at inside corners rather
than outside corners to avoid a pasted on look.
3.9 ADDITIONS/ACCESSORY BUILDINGS/SECONDARY
UNITS
•Site additions in the least conspicuous place. In many cases
this is a rear or side elevation - only rarely is it a rooftop.
•The existing built forms, components and materials should
be reinforced. Heights and proportions of additions and
alterations should be consistent with and continue the
original architectural style and design.
•Additions should be subordinate, and compatible in scale
and proportion to the historically significant portions of
the existing structure.
•When an addition or remodel requires the use of newly
constructed exterior elements, they should be identical in
size, dimension, shape and location as the original, and
Use stone or wood lintels over
openings in stone walls
Additions, accessory buildings and secondary
units should match the form, architectural
style, and details of the original house

should utilize the same materials as the existing protected
exterior elements.
•When an addition necessitates the removal of architectural
materials, such as siding, windows, doors, and decorative
elements, they should be carefully removed and reused in
the addition where possible.
•The introduction of window and door openings not char-
acteristic in proportion, scale, or style with the original
architecture is strongly discouraged (e.g., sliding windows or
doors in a structure characterized by double hung windows
and swinging doors).
•The character of any addition or alteration should be in
keeping with and subordinate to the integrity of the original
structure.
•The amount of foundation exposed on the addition should
match that of the original building.
•Do not add roof top additions where the roof is of historic
significance.
•Second floor additions are discouraged in neighborhoods
with largely one story homes. If horizontal expansion of
the house is not possible, consider incorporating a second
floor addition within the roof form as shown in the example
to the left.
•Second floor additions which are not embedded within the
roof form should be located to the rear of the structure.
•The height and proportion of an addition or a second story
should not dominate the original structure.
•Deck additions should be placed to the rear of the struc-
ture only, and should be subordinate in terms of scale and
detailing.
•New outbuildings, such as garages, should be clearly subor-
dinate to the main structure in massing, and should utilize
forms, materials and details which are similar to the main
structure.
•Garages should generally be located to the rear of the lot
behind the rear wall of the residence. One car wide access
driveways should be utilized.
Original structure
Addition incorporated into the roof
successfully adds space while respecting the
integrity of the existing house and the scale of
the neighborhood
Placing a two story addition to the rear can
minimize its impact on the historic resource
and the scale of the neighborhood
