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.
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)
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
2
grading, preserving existing vistas, incorporate site and architectural design that
is sensitive to the hillsides, and require fuel modification. The proposed addition
is concentrated above and along the rear of the existing footprint of the house
and the new balcony areas will not require any grading or excavation. No new
retaining walls are proposed. 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/covered patio areas throughout the
three levels of the home. 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'-
5'), 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;
The proposed addition 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 proposed addition will not be intrusive to neighboring homes
since the proposed addition will not block existing views from adjacent
properties. The property to the north will continue to have views of the vista from
their rear yard to the west and the property to the south will continue to have
views of the vista from their rear yard to the northwest. All properties to the east
will have views of the vista from their rear yard to the east.
With respect to privacy, the proposed third -level will not be intrusive to
neighboring properties for the following reasons.
2205 Indian Creek Road is approximately 200 feet from the proposed
addition, there are existing dense tall trees, and the property sits at a higher
elevation which prevents direct line of sight from the third level addition; and
• The proposed third level balcony, the only portion of the third -level addition
visible from 2137 Derringer Lane, is oriented predominantly west and will not
have greater impacts for privacy than the existing second level balcony.
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 addition are well balanced and
appropriate for the 1.89 gross -acre site. The Mediterranean 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, add throughout the two
levels of the house, and introduce a third level. The architectural style of the
existing home is a Mediterranean design with a balanced fagade, low-pitched
tiled roof, corbels beneath the eave, arched entryway, recessed windows,
decorative wrought -iron railings, and decorative trim surrounding the doors and
windows. Building materials consist of clay S-tile roofing, smooth stucco walls,
decorative stucco trim and corbels, wrought -iron details for balcony railings and
omamental grilles, and vinyl windows with metal frames that provide articulation
and depth across the fagade.
Through the use of quality materials with texture and color, the proposed
residence will not be intrusive to neighboring homes. The scale and proportions
of the proposed remodel and 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; and
4
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
Califomia 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 Findinas (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'-Y 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
Conditional Use Permit because the addition is not limited to the ground floor.
The 437 square -foot addition to the first level, 1,190 square -foot addition to the
second level, new 1,039 square -foot third level, 1,377 square -foot first -level
patio cover, and 1,190 square feet of balcony area 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 exterior remodel and the construction of a 437 square -foot addition to the
first level, 1,190 square -foot addition to the second level, new 1, 039 square -foot
third level, 1,377 square -foot first -level patio cover, and 1,190 square feet of
balcony area will not further encroach into the existing nonconforming 20'-5"
front setback. The Mediterranean architectural design of the remodeled home
5
is compatible with other homes 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 or result in potential privacy impacts.
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.
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:
1. 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'-5" 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.
0
2. Inconsistent with the general plan or any applicable specific plan.
The proposed addition to a 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. 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 and rear 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
comply with all conditions within 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.
5. Detrimental and/or injurious to improvements in the
property and 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
neighborhood
