B. RESOLUTION
NOW, THEREFORE, it is found, determined and resolved by the Planning Commission
of the City of Diamond Bar as follows:
1. The Planning Commission hereby specifically finds that all of the facts set forth
in the Recitals, Part A, of this Resolution are true and correct; and
2. The Planning Commission hereby determines the Project to be Categorically
Exempt from the provisions of the California Environmental Quality Act (CEQA)
pursuant to the provisions of Article 19, Section 15303(a) (construction of a new
single-family residence) of the CEQA Guidelines. Therefore, no further
environmental review is required.
C. FINDINGS OF FACT
Based on the findings and conclusions set forth 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 fagade [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;
2 PC 2023-10
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 the 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.
3 PC 2023-10
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 architect, 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.
