19.40.020 Applicability of regulations
No building or structure or land shall be used, and no building or structure shall be
hereafter erected, structurall� altered or enlarged in a residential hillside (RHS) zone,
otherwise than in conformance with the provisions of this chapter and other applicable
provisions of this title. (Ord. 1634 (part), 1993).
Notwithstanding any other provision of this chapter to the contrary, structures which were
legally constructed prior to the effective date of this ordinance shall be deemed legally
� conforming; provided, however, that any structural alteration, enlargement or remodeling
of such existing structure shall either comply with the site development regulations
(building coverage, setbacks, height restrictions and design standards) of this chapter or
shall obtain an exception as provided in Section 19.40.140.
19.40.050 B. Lot Area
The minimum lot area for a specific property shall correspond to the number following
the RHS zoning symbol (multiplied by one thousand square feet). Examples are as
follows:
Zoning Symbol Number Minimum Lot Area
- in Square Feet
�S 20 20,000
�g 40 - 40,000
�S gp 80,000
�S 120 120,000
�g 1 gp 180,000
�S 200 200,000
�S 400 400,000
For purposes of subdivision, the minimum lot area shall be the average lot area
computation for a zero percent slope gradient as contained in Appendix E of the General
Plan, unless clustered in accordance with Section 18.1.1303 (Hillside Subdivisions).
These lot sizes are approximately 12,000 sq. ft. for the Foothill Modified, 21,000 sq. ft.
for the Foothill 1/2 acre modified and 218,000 sq. ft. for the 5-20. The minimum lot size
. z
in a clustered subdivision is 10,000 sq. ft. Lots which potentially are_subdividatile will be
assigned a lot size number at the time of subdivision.
The minimum lot area for legally-created, developed lots, which are not subdividable, _
shall reflect the existing lot size.
19.40.050 F. Site Grading.
1. All site grading shall be limited to a cumulative total o� two thousand five hundred
cubic yards, cut plus fill. The two thousand five hundred cubic yards includes grading for
building pad, yard azeas, driveway and all other areas requiring grading, but . does not
include basements. The graded area shall be limited to the building pad area to the
greatest extent possible. Grad'mg quantities for multiple driveways shall be divided
equally among the participating lots, e.g., two lots sharing a driveway will divide the
driveway grading quantity in half. The divided share will be charged against the grading
quantity allowed for that lot development. A maximum of two thousand square feet of
flat yard area, excluding driveways, may be graded. All cut and fill areas shall be
rounded to follow the natural contours and- planted with landscaping which meets the -
requirements in Section 19.40.OSOG. - -

2) Side Yard. The minirnum side yard setback shall be fifteen feet. -
3) Rear Yard. The minunum rear yard setback shall be twenty-five feet. �
4� Downhill elevation. The downhill elevation shall be offset in the following manner:
at least 75% of the second story downhill facing wall plane shall be set back an average
of 7 and 1/2 feet and in no case less than 5 feet from the first story downhill wall plane.
The remaining 25% may not extend past the first story wall plane.
5) Should the downhill contours not be confined to one elevation, then the downhill
offset shall be applicable to the primary setback affected.
6) A second story offset may be measured from the outside perimeter of the first-story
� roofed porches. The roof of the porch must match, in pitch and style, the roof of the main
structure. The porch must also be at least five feet in width and extend the length of the
wall on which it is located. -
19.40.060 F. Height of Principal Buildings and Structures
1) The maximum height of a principal building in an RHS zone shall be thirty feet
(excluding chimneys, antennae, or other appurtenances).
- 2) Heights exceeding twenty feet shall be subject to the setback regulations prescribed in
Section 19.40.060D and E. (Ord. 1634 (part), 1993)
3) The maximum wall height on the downhill elevation shall be 15 feet.

shall trend downslope.
Item No.2. shall be deleted.
19.40.140 Exceptions for development of certain individual hiliside lots.
A. With respect to a request for development of a legally created individual hillside
lot which does not meet the development requirements contained in Section
19.40.050 D through M and 19.40.060 through .090 and 19.40.110 through .120
of this Chapter, the Planning Commission shall grant an exception to allow
development if the subject property cannot be merged with adjacent property
pursuant to Government Code Sections 66451.10-66451.21 and if the
commission, based upon substantial evidence, makes �11 of the following findings:
1) The proposed development will not be injurious to property or
improvements in the area nor be detrimental to the public health and
' safety.
2) The proposed development will not create a hazardous condition for
pedestrian or vehicular tr�c.
3) The proposed development has legal access to public streets and public
services aze available to serve the development.
4) The proposed developriient requires an exception which involves the least
modification of, or deviation from, the development regulations prescribed
in this Chapter necessary to accomplish a reasonable use of the parcel.
S) All alternative locations for development on the parcel have been
considered and have been found to create greater environmental impacts
than the location of the proposed development.
6) The proposed development does not consist of structures on or near known
geological or environmental hazards which have been determined by
expert testimony to be unsafe or hazardous to structures or persons
residing therein. (See General Plan Policies 2-49).
7) The proposed development includes grading and drainage plans which will
ensure that erosion and scarring of the hillsides caused by necessary
construction of roads, housing sites, and improvements will be minimized.
(See General Plan Policies 2-53, 2-54, and 2-57.)
4
8) The proposed development does not consist of structures which would �
disrupt the natural silhouette of ridgelines as viewed from established
vantage points on the valley floor uriless either:
a) The location of a structure on a ridgeline is necessary to avoid
greater negative environmental impacts, or
b) The structure could not otherwise be physically located on the
parcel and the size of the structure is the min�mum which is
necessary to allow for a reasonable use of the parcel. (See General
Plan Policies 2-46, 2-47, and 2-48.)
9) The proposed development consists �of structures incorporating designs,
colors, materials, and outdoor lighting which blend with the natural
hillside environment and which are designed in such a manner as to reduce
the effective visible mass, including building height, as much as possible
without creating other negative environmental impacts. (See General Plan
Policies 2-46, 2-50, 2-51 and 2-52.) -�
10) The proposed development is located on the parcel as far as possible from
public open space preserves or parks (if visible therefrom) , riparian
corridors, and wild life habitats unless such location will create other,
more negative environmental impacts. (See General Plan Policies 2-55, 5-
14 and 5-28.)
11) The proposed development includes a landscape plan which retains as
many specimen trees as possible, which utilizes drought tolerant native
plants and ground covers consistent with nearby vegetation, and wluch
minimizes lawn areas. (See General Plan policies 2-54, 5-15, and 5-16).
12) The proposed development confines solid fencing to the areas near a
structure rather than around the entire site. (See General Plan policy 5-1'n.
13) The proposed development is otherwise consistent with the City's General
Plan and with the purposes of this Chapter as described in Section
19.40.010.
B. An application for exception must be submitted on a form as prescribed by the
Director of Community Development. The application shall be accompanied by a
