Project Description
Site Plan
As stated, the property’s gross lot area is 86,249 square feet (1.98 gross acres), which
includes a 29-foot wide private street easement along its frontage for Broken Twig
Road. The property is an irregularly-shaped lot with a net buildable area (i.e., minus the
private street easement and flood hazard area) of 72,310 square feet (1.66 acres). The
property is a hillside property with a descending slope that starts from the private street
easement to the rear property line.
The proposed house is situated toward the front of the lot, 30 feet from the edge of the
private street easement line on Broken Twig Road. The front elevation faces Broken
Twig Road. A driveway is proposed at the front of t he property, which leads into the side
yard to provide access to the four-car garage.
Grading Plan
The applicant is proposing to cut 1,052 cubic yards of soil and fill 2,480 cubic yards of
soil throughout the property to expand the existing building pad. Therefore, 1,428 cubic
yards would have to be imported to the site.
The applicant is proposing three tiers of retaining walls with a maximum height of four
feet at the rear of the property to support fills above the natural grade to expand the
buildable pad for the house. Additionally, a pair of tiered retaining walls, with a
maximum height of five feet, are proposed at the side of the property to support cuts
into the slope. All exposed portions of the proposed retaining walls will have a
decorative finish, with the use of split-faced block.

Development Review No. PL2023-6 Page 5 of 9
Architecture
The architecture proposed is a contemporary design with black clay tile on a hipped
roof, light-colored, smooth stuccoed wall surfaces, glass railings, dark bronze metal
fascia, dark bronze aluminum windows, and wood soffit underneath the eaves. The
simple, yet clean color scheme and materials enhances the minimalist style.
The proposed two-level house’s floor plan is comprised of the following components:
• First Floor – Common areas (entry, family room, kitchen with wok, dining room,
and theater), guest room with bathroom, exercise room with sauna, one
bathroom, two powder rooms, and a four-car garage.
• Second Floor – Master suite with a bathroom and walk-in closet, four bedrooms
with bathrooms, two libraries with powder room, and a laundry room.
• Patio and balcony areas totaling 918 square feet throughout the two levels of the
residence.
The floor area distribution is summarized on the following page:

The height of the building is 33’-3”, measured from the finished grade to the highest
point of the roofline.
Landscape Plan
The applicant is proposing a variety of trees to be planted throughout the pr operty,
including a 24-inch box olive tree, one 15-gallon crape myrtle tree, and three 15-gallon
Southern magnolia trees in the front and rear yards. Six existing trees will remain on the
property including three California pepper trees and three cottonwoo d trees. One
California pepper tree will be removed due its proximity to construction. This tree
species is not considered protected. Additionally, various 5 -gallon and 1-gallon shrubs
that have a variety of color, texture, and form are proposed throughout the front, side
and rear yards. Overall, landscaping consists of drought tolerant and non -invasive
species to minimize irrigation and reduce the area of turf. The project is required to
comply with the City’s Water Efficient Landscaping Ordinance, and c ompliance will be
verified during building plan check and final inspections.
The subject property is located within the Los Angeles County Fire Department “High
Fire Hazard Severity Zone.” Therefore, the proposed landscaping must comply with the
Fire Department’s Fuel Modification Plan requirements. The landscape plans will be
submitted for review and approval by the Fire Department during building plan check.
ANALYSIS:
Review Authority
The proposed project requires a land use approval through the De velopment Review
process. The analysis that follows provides the basis for staff’s recommendation to
approve the Development Review application.
Development Review (DBMC Chapter 22.48)
New construction of a single-family home requires Planning Commission approval of a
Development Review application. Development Review approval is required to ensure
compliance with the City’s General Plan policies, development standards, and design
guidelines, and to minimize adverse effects of the proposed project upon the
surrounding properties and the City in general.
As stated in Section 22.48.010 of the Development Code, the Development Review
process was established to ensure that new development and additions to existing
development are consistent with the General Plan “through the promotion of high
functional and aesthetic standards to complement and add to the economic, physical,
and social character” of Diamond Bar.

Compliance with Hillside Management Ordinance (DBMC Section 22.22)
The proposed project was reviewed for compliance with the City’s Hillside Management
Design Guidelines and regulations. The project complies with all of the regulations and
guidelines to ensure that development will complement the character and topography of
hillside areas set forth in the Development Code, and incorporate s the following
features:
• The maximum building height is 33’-3” feet, where 35 feet is allowed;
• Architectural treatment is provided on all sides of the building with varying setbacks;
• All proposed retaining walls associated with the building pads are at a maximum
exposed height of four feet; and
• Earth tone building materials and color schemes are used that blend in with the
natural landscape.
Compatibility with Neighborhood
The house is located on an existing leveled pad but will be extended for the bu ilding
footprint expansion and rear yard improvements. The new house will not be intrusive to
neighboring homes since the proposed house will not block existing views from adjacent
properties. The adjacent house to the north has views to the west. The h ome to the
7.1
Packet Pg. 16
Development Review No. PL2023-6 Page 8 of 9
northeast maintains views in all directions. Properties to the west and east are
undeveloped.
The proposed house is comparable in mass and scale to existing homes on similar lots
in The Country. The architecture in The Country is eclectic, an d includes a variety of
architectural designs. The scale and proportions of the proposed home are well
balanced and appropriate for the site. In sum, the proposed project fits the character of
the neighborhood on which it is proposed. Additionally, three California pepper trees
exist on the lot to the north and a Brazilian pepper tree to the east that are proposed to
remain, which will provide screening between the subject property and the neighboring
properties.
The project incorporates the principles of the City’s Residential Design Guidelines as
follows:
• The new single-family residence will conform to all development standards,
including building height and setbacks, which is consistent with other homes in
The Country;
• A gradual transition between the project and adjacent uses is achieved through
appropriate setbacks, building height, landscaping, and window and door
placement;
• The proposed new single-family residence is appropriate in mass and scale to
the site;
• Elevations are treated with detailed architectural elements;
• The exterior finish materials and colors blend with the natural environment; and
• Effective landscape design should serve the dual purpose of intrinsically
enhancing a project setting, as well as integrating the landscaping into the ov erall
architectural design. Staff finds the proposed plant palette to be diverse, and the
plant selections are compatible with Southern California native landscapes.

Based on the findings and conclusions set fo rth herein and as prescribed under
Diamond Bar Municipal Code (DBMC) Section 22.48, this Planning Commission hereby
finds as follows:
Development Review Findings (DBMC Section 22.48.040)
1. The design and layout of the proposed development is consistent with the
applicable elements of the City's General Plan, City Design Guidelines, and
development standards of the applicable district, design guidelines, and
architectural criteria for special areas (e.g., theme areas, specific plans,
community plans, boulevards or planned developments):
The design of the Project is consistent with the applicable elements of the City’s
General Plan, City Design Guidelines and development standards. The City’s
General Plan Policy LU-P-56 requires that development on privately-owned,
residentially designated land in hillside areas shall be compatible with the
surrounding natural areas promoting design principles such as minimizing
grading, preserving existing vistas, incorporate site and architectural design that
is sensitive to the hillsides, and require fuel modification. A contemporary design
is being proposed with black clay tile on a hipped roof, light-colored, smooth
stuccoed wall surfaces, glass railings, dark bronze metal fascia, dark bronze
aluminum windows, and wood soffit underneath the eaves. The simple design
and colors are used as not to detract from the hillsides. The Project will also be
required to implement fuel modification.
A gradual transition between the project and adjacent uses is achieved through
appropriate setbacks, building height, and window and door placement.
Additionally, the design includes balcony and patio areas throughout the two
levels of the home. All elevations are architecturally treated and strongly
articulated along the visible façade [City’s Design Guidelines B. Architecture (3)].
The Project complies with all development standards of the Rural Residential
zoning district by complying with all development standards such as required
setbacks, building height, and lot coverage. The project site is not part of any
theme area, specific plan, community plan, boulevard or planned development.
2. The design and layout of the proposed development will not interfere with the use
and enjoyment of neighboring existing or future developments, and will not create
traffic or pedestrian hazards;
7.1.a
Packet Pg. 20
3 PC Resolution No. 2023-XX
The proposed single-family house will not interfere with the use and enjoyment
of neighboring existing or future developments because the use of the project site
is designed for a single-family home and the surrounding uses are also single -
family homes. The new house will not be intrusive to neighboring homes since
the proposed house will not block existing views from adjacent properties. The
adjacent house to the north has views to the west. The home to the northeast
maintains views in all directions. Properties to the west and east are
undeveloped.
The proposed single-family house will not interfere with vehicular or pedestrian
movements, such as access or other functional requirements of a single-family
home because it complies with the requirements for driveway widths and exceeds
the minimum number of required off-street parking spaces.
3. The architectural design of the proposed development is compatible with the
character of the surrounding neighborhood and will maintain and enhance the
harmonious, orderly and attractive development contemplated by Chapter 22.48:
Development Review Standards, the City’s Design Guidelines, the City's General
Plan, or any applicable specific plan;
The City’s General Plan Policy LU-P-56 requires that residential development be
compatible with the prevailing character of the surrounding neighborhood in
terms of building scale, density, massing, and design. The City’s General Plan
Goal CC-G-4 also requires the preservation of the scale and character of existing
residential neighborhoods and ensure sensitive transitions between densities
and uses. The City’s Design Guidelines Architecture (1) requires compatibility
with the surrounding character including harmonious building style, form, size,
color, material and roofline.
The scale and proportions of the proposed residence are well balanced and
appropriate for the 1.98 gross acre site. The contemporary architectural style is
compatible with other homes in the neighborhood since the architecture in The
Country is eclectic, and includes a variety of architectural designs. The Project
minimizes negative impacts on surrounding uses since the house will not block
existing views from adjacent properties. In sum, the Project fits the character of
the neighborhood on which it is proposed.
4. The design of the proposed development will provide a desirable environment for
its occupants and visiting public as well as its neighbors through good aesthetic
use of materials, texture, color, and will remain aesthetically appealing;
The applicant is proposing a contemporary design with black clay tile on a hipped
roof, light-colored, smooth stuccoed wall surfaces, glass railings, dark bronze
metal fascia, dark bronze aluminum windows, and wood soffit underneath the
eaves. The simple, yet clean color scheme and materials enhances the
minimalist style.
7.1.a
Packet Pg. 21
4 PC Resolution No. 2023-XX
The proposed residence will not be intrusive to neighboring homes. Light colored
shades for the exterior finish are used to soften the building’s visual impact and
assist in preserving the hillside’s aesthetic value. Also, landscaping is integrated
into the site to complement the massing of the house and blend in with
neighboring homes and the natural environment of the site in order to maintain a
desirable environment. The scale and proportions of the proposed home are well
balanced and appropriate for the site.
5. The proposed development will not be detrimental to public health, safety or
welfare or materially injurious (e.g., negative effect on property values or
resale(s) of property) to the properties or improvements in the vicinity; and
Before the issuance of any City permits, the proposed project is required to
comply with all conditions within the approved resolution, and the Building and
Safety Division and Public Works Departments requirements.
Through the permit and inspection process, the referenced agencies will ensure
that the proposed project is not detrimental to the public health, safety or welfare
or materially injurious to the properties or improvements in the vicinity.
6. The proposed project has been reviewed in compliance with the provisions of the
California Environmental Quality Act (CEQA).
The proposed project is categorically exempt from the provisions of the California
Environmental Quality Act (CEQA) as set forth under Article 19 Section 15303(a)
(construction of a new single-family residence) of the CEQA Guidelines.
Based upon the findings and conclusion set forth above, the Planning Commission hereby
approves this Application, subject to the following conditions:
1. Development shall substantially comply with the plans and documents presented
to the Planning Commission at the public hearing.
2. Prior to building permit issuance, the required landscape plan shall be designed
to meet the requirements of the Los Angeles County Fire Department’s Fuel
Modification Plan Guidelines in terms of plant selection, placement and
maintenance. The final landscape and fuel modification plans shall be submitted
to the Los Angeles Fire Department for review and approval.
3. Prior to building permit issuance, a Certification of Design, together with
landscape and irrigation plans prepared by a licensed landscape arch itect, shall
be submitted to the Planning Division for review and approval by the City’s
Consulting Landscape Architect. Landscape and irrigation plans shall comply
with the updated Water Efficient Landscaping Ordinance.
4. Standard Conditions. The applicant shall comply with the standard development
conditions attached hereto.
