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 15301(e) (additions to existing
structures) 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 City Code (DBCC) Sections 22.48, 22.56 and 22.68, this Planning
Commission hereby finds as follows:
Development Review Findings (DBCC 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. To minimize grading,
the addition is proposed on an existing buildable pad which will be expanded to
comply with the minimum rear yard setback. All exposed portions of retaining
walls will have a decorative finish, with the use of stucco to match the house as
to not detract from the hillside. 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 deck and balcony areas along the side and rear
of the home, which further contributes to articulation. All elevations are
architecturally treated and strongly articulated through projections 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 (with the exception of the existing nonconforming front setback of 20'-
6'), building height, and lot coverage. The project site is not part of any theme
2 PC RESOLUTION NO.2025-OB
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.
The proposed addition 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 proposed addition will not be intrusive to neighboring homes
since the proposed addition will not block existing views from adjacent properties.
The adjacent property to the north has views to the west and the adjacent
property to the south also have views to the west.
The proposed addition will not interfere with vehicular or pedestrian movements,
such as access or otherfunctional 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-G4 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 addition are well balanced and
appropriate for the 0.65 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 to remodel the entire house and add to the side and
rear of the existing house. The architectural style of the existing home is Neo-
Mansard with an oversized mansard roof, a recessed entry, small window
openings, and a rectangular building form. The applicant is proposing to redesign
in a contemporary architectural style, featuring a minimalist exterior defined by
clean lines, geometric wall planes and incorporates the following design
I PC RESOLUTION NO. 20M06
elements:
• A flat roof with varying heights to break up the roof massing;
Exterior fagade consisting of painted stucco, imitation -wood fiber cement
siding and metallic trims, with the use of projections and articulation;
• Vinyl windows of various sizes and configurations;
• Black aluminum deck/balcony railings and exterior wooden gates; and
• Simple color scheme, which includes white and gray stucco walls in
combination with earthen brown accent siding. Windows, doors and
decorative trims include variations of brown, bronze and black, which
complements the neutral color tones of the walls.
Through the use of quality materials with texture and color, the proposed
residence will not be intrusive to neighboring homes. Additionally, landscaping is
integrated into the site to complement the streetscape and maintain a desirable
environment. The scale and proportions of the proposed addition 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.
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 15301(e)
(additions to existing structures) of the CEQA Guidelines,
Minor
Conditional Use Permit Findings (DBCC Section 22.56.040)
1.
The proposed use is allowed within the subject zoning district with the approval
of a Minor Conditional Use Permit and complies with all other applicable
provisions of this Development Code and the City Code.
The existing single-family dwelling is a permitted use in the RR zone. A Minor
Conditional Use Permit (MCUP) is requested to allow the continuation of an
existing nonconforming structure with a preexisting nonconforming 20'-6" front
setback (where 30 feet is required).
The pre-existing substandard front setback renders the project nonconforming.
The addition to a nonconforming structure requires approval of a Minor
4 PC RESOLUTION NO.2025-06
Conditional Use Permit because the addition is not limited to the ground floor.
The 555-square-foot addition to be legalized and proposed 385-square-foot two-
story addition and 281-square400t balcony complies with the development
standards of the RR zone and will not further encroach into the nonconforming
front setback.
2. The proposed use is consistent with the general plan and any applicable specific
plan.
The proposed addition to an existing single-family dwelling unit is consistent with
the City's adopted General Plan. The site is not subject to the provisions of any
specific plan.
3. The design, location, size and operating characteristics of the proposed use are
compatible with the existing and future land uses in the vicinity.
The existing 555-square-foot addition to be legalized, the proposed 385 square
feet of additional living area and 281-square-foot balcony will not further encroach
into the existing nonconforming 20'-6" front setback. The contemporary
architectural design of the remodeled home is compatible with otherhomes in the
neighborhood, as the architecture in The Country is eclectic and includes a
variety of architectural styles. The Project also minimizes negative impacts on
surrounding uses, as the house will not block existing views from adjacent
properties. Therefore, the Project is compatible with the existing and future land
uses in the vicinity.
4. The subject site is physically suitable for the type and density/intensity of use
being proposed including access, provision of utilities, compatibility with adjoining
land uses, and the absence of physical constraints.
The subject site is physically suitable for the existing single-family residential
dwelling and the proposed addition. The existing and proposed use of land is
consistent with the surrounding land uses. The proposed addition is consistent
with the development standards for the RR zone and will not further encroach
into the existing nonconforming front setback.
5. Granting the Minor Conditional Use Permit will not be detrimental to the public
interest, health, safety, convenience or welfare, or materially injurious to persons,
property or improvements in the vicinity and zoning district in which the property
is located.
The granting of the Minor Conditional Use Permit will allow the addition of the
existing single-family dwelling unit in a manner similar with existing dwelling units
located in the surrounding neighborhood. The proposed expansion of the
dwelling unit will not negatively impact the public interest, health, safety,
convenience or welfare.
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 15301
(e) (additions to existing structure) of the CEQA Guidelines.
PC RESOLUTION N0. 2025-05
Non -Conforming Structures Findings (DBCC Section 22.68.030)
The addition, enlargement, extension, reconstruction, relocation or structural alteration
of the nonconforming structure would not result in the structure becoming:
Incompatible with other structures in the neighborhood.
The proposed addition of floor area is consistent with the development standards
for the RR zone. The Project will comply with current development standards
and not further encroach into the existing nonconforming 20'-6" front setback.
The existing and proposed land use is consistent with the surrounding land uses
and structures in the neighborhood. Additionally, the neighboring properties also
have nonconforming front setbacks, so the proposed project will remain
consistent with other homes within the neighborhood.
2. Inconsistent with the general plan or any applicable specific plan.
The proposed addition to asingle-family dwelling unit is consistent with the City's
adopted General Plan. The site is not subject to the provisions of any specific
pIan.
3. A restriction to the eventual/future compliance with the applicable regulations of
this Development Code.
The existing and proposed land use is consistent with the surrounding land uses
with similar front setbacks. The proposed addition of floor area is consistent with
the development standards for the RR zone and will not encroach into the existing
nonconforming front setback.
4. Detrimental to the health, safety and general welfare of persons residing in the
neighborhood.
Before the issuance of any City permits, the proposed project is required to
cVI ply with all conons wn the approved resolution, and the Building and
Safety Division and Public Works/Engineering 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.
Detrimental and/or injurious to property and improvements in the neighborhood.
The addition to the existing single-family dwelling unit will be constructed in a
manner similar with existing dwelling units located in the surrounding community
and will not be detrimental and/or injurious to property and improvements in the
