B. RESOLUTION
NOW, THEREFORE, it is found, determined and resolved by the Planning
Commission of the City of Diamond Bar as follows:
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. In accordance to the provisions of the California Environmental Quality Act
(CEQA), Section 15070, the City prepared and filed an Initial Study and Notice
of Intent to Adopt Negative Declaration for the project on April 28, 2011, with
the Los Angeles County Clerk. Pursuant to CEQA Section 15105, the public
review period for the Negative Declaration began April 29, 2011, and ended
May 18, 2011.
C. FINDINGS OF FACT
Based on the findings and conclusions set forth herein and as prescribed under
Diamond Bar Municipal Code (DBMC) Section 21.20, this Planning Commission
hereby recommends that the City Council make the following findings:
The Planning Commission hereby specifically finds and determines that, having
considered the record as a whole including the findings set forth below, and
changes and alterations which have been incorporated into and conditioned
upon the proposed project set forth in the application, there is no evidence
before this Planning Commission that the project proposed herein will have the
potential of an adverse effect on wild life resources or the habitat upon which
the wildlife depends. Based upon substantial evidence, this Planning
Commission hereby rebuts the presumption of adverse effects contained in
Section 753.5(d) of Title 14 of the California Code of Regulations;
Tentative Map Findings: Pursuant to Subdivision Code Section 21.20.080 of
the City's Subdivision Ordinance, the Planning Commission recommends that
the City Council make the following findings:
a. The proposed subdivision, together with the provisions for its design and
improvement, is consistent with the general plan and any applicable
specific plan;
The proposed project involves the subdivision of an existing vacant
133,697 square -foot (3.07 acres) gross lot into two separate lots for the
development of a single-family residence on each lot. Proposed Parcel 1
is 73,283 square -feet (1.68 acres) and Parcel 2 is 60,414 square -feet
(1.34 acres). The property is zoned Rural Residential with a consistent
underlying General Plan land use designation. The development of a
single-family residence on each lot will be processed through a
Development Review application for compliance with the City's General
Plan, City Design Guidelines and development standards. The project
will provide additional homeownership opportunities of single-family
housing that will be compatible with the surrounding development.
The project site is not part of any theme area, specific plan, community
plan, boulevard or'planned development.
2
TPM No 71362 PL 2010-128
b. The site is physically suitable for the type and proposed density of
development;
The proposed subdivision will not interfere with the use and enjoyment of
neighboring existing or future developments because the use of each lot
is for a single-family home and the surrounding uses are also single-
family homes. The maximum allowed density for the Rural Residential
general plan land use designation and zoning district is one dwelling unit
per gross acre (1 DU/Acre). Therefore, with a 3.07 acre lot, the
proposed project is iri compliance with the City's General Plan with
regards to density. Also, the proposed location of the building pads and
footprints are in compliance with the development standards and the
retaining walls associated with the lot pads are designed to be four feet
high.
C. The design of the subdivision or the proposed improvements will not
cause substantial environmental damage or injure fish or wildlife or their
habitat;
Pursuant to the provisions of the California Environmental Quality Act
(CEQA) Section 15168 et seq., an Initial Study/Environmental Checklist
and Negative Declaration has been prepared for the application and
found that the proposed project would not have any potentially significant
impacts, on the environment.
d. The design of the subdivision or type of improvements will not cause
serious public health or safety problems;
The grading will be constructed, operated, and maintained in accordance
with the recommendations contained in the preliminary geotechnical
investigation to assure that geotechnical stability is maintained or
increased. Detailed drainage and hydrology studies will be completed,
including the potential for debris flows, and the proposed conditions of
approval will likely prevent any significant increases in erosion and flood
hazards.
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, and Los
Angeles County Fire Department 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.
e. The design of the subdivision or type of improvements will not conflict
with easements, acquired by the public at large for access through or
use of, property within the proposed subdivision.
3
TPM No. 71362 PL 2010-128
The site does not have any access easements on-site. However, the
proposed project is conditioned to dedicate an easement in front of the
property as part of the private street.
The proposed subdivision 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.
The discharge of sewage from the proposed subdivision into the
community sewer system would not result in violation of existing
requirements prescribed by the California Regional Water Quality Control
Board;
The proposed subdivision will not violate any requirement of the
California Regional Water Quality Control Board. To reduce water
quality impacts to a level less than significant, the proposed subdivision
is required to comply with the California Regional Water Quality Control
Board, Federal Clean Water Act, and the National Pollutant Discharge
Elimination System (NPDES) program, implementing construction -
related Best Management Practices (BMP's) and Standard Urban
Stormwater Mitigation Plan (SUSMP) criteria. With project design
features related to the storm drain system and conditions of approval,
potentially significant water quality impacts would be reduced to a levels
less than significant.
g. A preliminary soils report or geologic hazard report does not indicate
adverse soil or geologic conditions; and
The grading will be constructed, operated, and maintained in accordance
with the recommendations contained in the preliminary geotechnical
investigation to assure. that geotechnical stability is maintained or
increased.
h. The proposed subdivision is consistent with all applicable provisions of
the City's subdivision ordinance, the development code, and the
subdivision map act.
The proposed subdivision is consistent with the City's subdivision
ordinance, subdivision map act, and applicable development code. In
addition, the development of a single-family residence on each lot will be
processed through a Development Review application for compliance
with the City's development standards.
2. Based on the findings, and conclusions set forth herein, the Planning
Commission hereby recommends that the City Council approve Tentative
Parcel Map No. 71362, subject to the following conditions and the attached

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. In accordance to the provisions of the California Environmental Quality Act (CEQA), Section 15070, the City prepared and
filed an Initial Study and Notice of Intent to Adopt Negative Declaration for the project on April 28, 2011, with the Los Angeles
County Clerk. Pursuant to CEQA Section 15105, the public review period for the Negative Declaration began April 29, 2011, and
ended May 18, 2011.
C. FINDINGS OF FACT
Based on the findings and conclusions set forth herein and as prescribed under Diamond Bar Municipal Code (DBMC) Section 21.20,
this Planning Commission hereby recommends that the City Council make the following findings:
1. The Planning Commission hereby specifically finds and determines that, having considered the record as a whole including the
findings set forth below, and changes and alterations which have been incorporated into and conditioned upon the proposed project
set forth in the application, there is no evidence before this Planning Commission that the project proposed herein will have the
potential of an adverse effect on wild life resources or the habitat upon which
the wildlife depends. Based upon substantial evidence, this Planning Commission hereby rebuts the presumption of adverse effects
contained in Section 753.5(d) of Title 14 of the California Code of Regulations;
Tentative Map Findings: Pursuant to Subdivision Code Section 21.20.080 of the City's Subdivision Ordinance, the Planning
Commission recommends that the City Council make the following findings:
a. The proposed subdivision, together with the provisions for its design and improvement, is consistent with the general plan and
any applicable specific plan;
The proposed project involves the subdivision of an existing vacant 133,697 square -foot (3.07 acres) gross lot into two separate lots
for the development of a single-family residence on each lot. Proposed Parcel 1 is 73,283 square -feet (1.68 acres) and Parcel 2 is
60,414 square -feet (1.34 acres). The property is zoned Rural Residential with a consistent underlying General Plan land use
designation. The development of a single-family residence on each lot will be processed through a Development Review application
for compliance with the City's General Plan, City Design Guidelines and development standards. The project will provide additional
homeownership opportunities of single-family housing that will be compatible with the surrounding development.
The project site is not part of any theme area, specific plan, community plan, boulevard or planned development.
2
TPM No 71362 PL 2010-128
b. The site is physically suitable for the type and proposed density of development;
The proposed subdivision will not interfere with the use and enjoyment of neighboring existing or future developments because the
use of each lot is for a single-family home and the surrounding uses are also single- family homes. The maximum allowed density
for the Rural Residential general plan land use designation and zoning district is one dwelling unit per gross acre (1 DU/Acre).
Therefore, with a 3.07 acre lot, the proposed project is in compliance with the City's General Plan with regards to density. Also, the
proposed location of the building pads and footprints are in compliance with the development standards and the retaining walls
associated with the lot pads are designed to be four feet high.
C. The design of the subdivision or the proposed improvements will not cause substantial environmental damage or injure
fish or wildlife or their habitat;
Pursuant to the provisions of the California Environmental Quality Act (CEQA) Section 15168 et seq., an Initial Study/Environmental
Checklist and Negative Declaration has been prepared for the application and found that the proposed project would not have any
potentially significant impacts on the environment.
d. The design of the subdivision or type of improvements will not cause serious public health or safety problems;
The grading will be constructed, operated, and maintained in accordance with the recommendations contained in the preliminary
geotechnical investigation to assure that geotechnical stability is maintained or increased. Detailed drainage and hydrology studies
will be completed, including the potential for debris flows, and the proposed conditions of approval will likely prevent any significant
increases in erosion and flood hazards.
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, and Los Angeles County Fire Department
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.
e. The design of the subdivision or type of improvements will not conflict with easements, acquired by the public at large for
access through or use of, property within the proposed subdivision.
3
TPM No. 71362 PL 2010-128
The site does not have any access easements on-site. However, the proposed project is conditioned to dedicate an easement in
front of the property as part of the private street.
The proposed subdivision 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.
f. The discharge of sewage from the proposed subdivision into the community sewer system would not result in violation of
existing requirements prescribed by the California Regional Water Quality Control Board;
The proposed subdivision will not violate any requirement of the California Regional Water Quality Control Board. To reduce water
quality impacts to a level less than significant, the proposed subdivision is required to comply with the California Regional Water
Quality Control Board, Federal Clean Water Act, and the National Pollutant Discharge Elimination System (NPDES) program,
implementing construction- related Best Management Practices (BMP's) and Standard Urban Storm water Mitigation Plan (SUSMP)
criteria. With project design features related to the storm drain system and conditions of approval, potentially significant water
quality impacts would be reduced to a levels less than significant.
g. A preliminary soils report or geologic hazard report does not indicate adverse soil or geologic conditions; and
The grading will be constructed, operated, and maintained in accordance with the recommendations contained in the preliminary
geo technical investigation to assure that geotechnical stability is maintained or increased.
h. The proposed subdivision is consistent with all applicable provisions of the City's subdivision ordinance, the development
code, and the subdivision map act.
The proposed subdivision is consistent with the City's subdivision ordinance, subdivision map act, and applicable development code.
In addition, the development of a single-family residence on each lot will be processed through a Development Review application
for compliance with the City's development standards.
