8.1 DEVELOPMENT REVIEW 2004-34 - In accordance with Chapter 22.48 of
the City of Diamond Bar Development Code, the applicant requested approval of
plans to construct an approximate 8,076 square foot addition to an existing 2,777
square fo�t two-story single-family dwelling on an existing 9.10 acre R-1 9,OOQ
zoned parcel with a consistent underlying General Plan Land Use designation of
Low Density Residential (RL). The development also included an attached 1,008
square foot 4-car garage, swimming pool, tennis court, basketball court and
detached gazebo. (Continued from June 28, 2005)
PRUJCECT ADDRESS: 701 Featherwood Drive
Diamond Bar, CA 91765
PROPERTY OWNER/ Randy and Olga Rodriquez
APPLICANT: 701 Featherwood Drive
Diamond Bar, CA 91765
PM/Godinez presented staff's report and recommended that the Planning
Cornmission adopt Development Review 2004-34, Findings of Fact and conditions
of approval as listed within the resolution.
Chair/McManus asked if the garage door scheduled for removal was on the west
side of the house as stated in staff's report and PM/Fong confirmed that it was.
PM/Fong indicated to VC/Low that it was intended to be a two-story connection that
would include a garage door through which the owner could drive to access an
interior courtyard with a four-car garage.
Randy Rodriquez asked why he was conditioned to reduce the 18-foot wide
driveway to 12 feet. PM/Fong used the photographs to clarify that staff's request
was for the new portion of driveway orily to be reduced from 18 feet to 12 feet to
conform to code.
Etiy T��n�
JULY 12, 2005 Page 3 PLANNING COMMISSION
C/Tye asked why staff would condition to rediace the driveway rather than conform
to the existing driveway? PM/Fong responded that certain factors were considered
such as whether there was a need for si�ach a wide driveway because the exisfing
driveway supported the dwelling. If the new d riveway were widened to 18 or 20 feet
it would create a lot of unnecessary hardscape �that would be visible from the
eastbound SR 60.VC/Low felt that the wider driveway would not burden the already
hiage property. PM/For�g responded that the Plar�ning Commission could direct staff
to work with the applicant to see if a wider diiveway was feasible. VC/Low believed
that due to �khe steep incline it would be difficult for someone to maneuver a large
SUV in the narrow driveway in the dark for instance. C/Tye said he still did not
understand staff's concern and endorsed VC/Low's point of view to work with the
applicant toward providing a larger driveway. He was not sure that it would be that
visible from the SR60 and he also felt that it would be safer for the applicant to be
able to drive up a larger driveway.
Mr. Rodriquez explained that he created a wide driveway because it helped create a
firebreak. Every year the fire department required him to clear everything within 100
feet of his residence. Visitors to his home find it difficult to maneuver their vehicles
in an area that is too small and that would include the fire department because�they
drive their trucks up to his property to view the surrounding area.
VC/Low said that during her visit with Mr. Rodriquez today she discerned that he
intended to move the pepper tree at the�front of the residence and did not find that
this project had required approval for a tree permit. PM/Fong felt that it would be
preferable for the applicant to preserve the tree in its current location if possible.
However, if the applicant wanted to move the tree he could apply for a tree permit.
Chair/McManus opened the public hearing.
Mark Sackett, 711 Featherwood Drive, said he was concerned that property safety
precautions were in place during a project of this magnitude so that it would not
impede on the surrounding community and neighborhood. He was concerned about
noise, water drainage and fire prevention and his biggest concern was if the
applicant was allowed to have such a driveway that a two-lane road would take
precedence and that the area would eventually be zoned for High Density. He would
prefer that the R-1 zone remain in place. He wanted to be sure that the excavation
would not affect the stability of the hillside so that he had to be concerned about the
possibility of a fiature landslide. He felt the project was aesthetically pleasing and
said he believed it would be a good addition to the neighborhood.

JIILY 12, 2005 Page 4 PLANNING COMMISSION
Chair/McManus pointed out that as part of the approval process the applicants sign
a covenant that the praperty will remain a single-family residence. There will be
some noise during construction. With respect to geotechnical issues, since
Diamond Bar incorporated none of the hills that have been built upon have suffered
landslides. Only hillsides that were developed prior to incorporation have suffered
landslides. Staff is diligent about requiring proper mitigation. PM/Fong assured the
speaker that the applicant was required to submit geotechnical reports and that the
area would have to be found adequate to support grading and structures prior to
issuance of building permits.
PM/Fong responded to VC/Low that the property is zoned for single-family
residences only. If the property owner wanted to change the zoning to multiple
family he would have to request a General Plan amendment and zone change. She
said that the applicant could propose a subdivision but there is only one access to
the property and the driveway is very small. The subdivision map has requirements
regarding access to a public street for any subdivision so it would not be feasible
with the narrow access.
ACIVI/DeStefano said that not only is the property zoned single-family residential, it
is classified in the City's Master Plan (the General Plan) as single-family residential.
As PNUFong stated it would require a subdivision of property and a General Plan
amendment to change the designation. Any interest in changing the designation of
the property requires public hearings before the Planning Commission and the City
Council and it would be very unlikely that staff would recommend any such changes
due to the limited access and because it is a single family neighborhood.
Marguerita Lopez, 675 N. Featherwood Drive said she wanted assurance that the
proposed project would be used to house only one family because it is a very big
house. Chair/McManus indicated that the applicants have five sons. Ms. Lopez said
she was also concerned that the house would not obstruct her view and wanted to
be sure the fire deparkment would coritinue to monitor the area.
Chair/McManus closed the public hearing.
C/Tye said he had experienced the same concern as the speakers that becaiase it
was such a large parcel that it might be subject to subdividing.
VC/Low felt that if the property owners intended to maintain the property and put in
a wider driveway that would serve to deter fire as well as landscape the area in a
reasonable fashion it would be served as an improvement for the corrimunity.

In accordance with Code Sections 22.48.020(a)(1)and 22.38 of the City of Diamond
Bar Development Code, this was a request to construct a three-story single-family
residence with two garages for a total of five parking spaces,and balconies totaling
to approximately 16,719 square feet.The request also included front, side and rear
yard retaining walls not to exceed an exposed height of seven feet and a tennis
court in the rear yard. The Tree permit was related to the removal and replacement
of oak and walnut trees.

Pete Volbeda, Architect explained that most of the exported dirt would be removed
to adjacent sites in accordance with agreements between the applicant and
adjacent property owners. In fact, most the fill taken from the hillside would be used
to balance the site and provide a surface for a tennis court for Mr. Chin. The
applicant does not plan to export dirt offsite. In addition, the retaining wall against
Mr. Chin's garage will be removed to create a balance between his and Dr. Ha's
property. In the end the property will be level �From Mr. Chin's property to Loren
Phillip's property.
C/Torng asked Mr. Vofbeda to elaborate on whether "The Country Estates"
Homeowners Assaciation required all neighbors to sign off on the project.
Mr. Volbeda explained that Tim Goode suggested that the applicant approach the
neighbors about lowering the grade because the initial design contained 10-foot
retair�ing walls along the side and that Mr. Goode required onlythe signatures of the
affected property owners to allow the applicant to move forward.
VC/Low asked if"The Country Estates" architectural review committee had signed
off on the project and Mr. Volbeda responded "no" because he was waiting for�the
signatures and had just received Mr. Phillip's signature today. PM/Fong stated that
the review contains a condition that the applicant must obtain association approval
prior to the issuance of permits.
Chair/McManus opened the public hearing.
With no one present who wished to speak on tr�is item, Chair/McManus closed the
public hearing.
VC/Low moved, C/Torng seconded, to approve Development Review No. 2004-39

PM/Fong responded to C/Yorng that in the instance of the project within "The
Country Estates°the homeowner's association required signatures related only to
the grading because it involved private property not owned by the applicant.
C/Tye congratulated Jack Tanaka and welcomed C/Torng.
VC/Low congratulated Jack Tanaka on being elected to serve on the City Council
and thanked him for his quiet leadership, insight and help and for his service to the
Planning Commission. She welcomsd C/Torng and said it was a fun Commission
that did a lot of neat things.
Chair/McManus khanked Jack Tanaka for his service to the Commission and
congratulated him on moving up to the City Council. He welcomed C/Torng to the
Planning Corrirriission.
10. STAFF COMMENTS AND INFORMATIONAL ITEMS: ACM/DeStefanostated
that the Schedule of Public Meetings indicated a Zoning Map Amendment
discussion for July 26 that would be pushed out to August. As a result, there were
no items scheduled for the July 26 meeting. Last'fhursday evening the City Co�incil
subcommittee held a town hall meeting for the Industry Business Center project at
Armstrong Elementary School. About 2300 property owners were noticed in the
immediate area. The Planning Director for the City of Industry spoke to the project
and responded to questions.About 130 individuals attended the meeting and about
two-dozen speakers voiced their opinions and asked questions about�the proposed
development. In the past, Industry has been a good neighborand the City expects
that will continue.When more specific information is ava'ilable the subcommittee will
hold additional town hall meetings. The meeting lasted approximately three hours.
ACM/DeStefano responded to ChairlMcManus that Washington, Beaverhead and
Sunset Crossing Road are cul-de-sacs within the scope of the City's General Plan
and Diamond Bar controfs whether those streets are open and connected and
Diamond Bar has insisted that those streets remain cul-de-sacs. If the streets were
ever to be considered to be open it would require a public noticed General Plan
process before the Planning Commissian and then before the City Council and
would undoubtedly involve extensive traffic studies, etc.

ACM/DeStefano stated that the street work at Grand Avenue and Golden Springs
Drive has commenced with the urban forestry program. As a result, a number of
trees have been lost to the project that contemplates widening Golden Springs Drive
to create a second right-turn lane and a much longer series of right turn lanes as
well as an additional lane on Grand Avenue from the freeway toward Montefino.The
additional lanes are intended to transition traffic from the freeway through Diamond
Bar and to serve as a deceleration lane into the shopping center and later an
acceleration lane to move traffic forward toward Chino Hills in a safer manner.Work
is scheduled for completion about the middle of November. The Target project is
moving forward with commencement of construction slated for mid-August. The
Brookfield condominiums are scheduled for construction beginning about mid-
September with the first units offered for sale at the end of 2005 and occupancy
scheduled between June 2006 and 2007.
ACM/DeStefano reported that the City had been interested in a sphere of influence
change forthe past couple of years in orderto capture the triangularshaped area at
Diamond Bar Boulevard at Brea Canyon cutoff near the Diamond Canyon Church.
The 100-acre area that has a Diamond Bar zip code, Walnut School District and is
served by the Diamond Bar/Walnut Sheriff's station lies within Los Angeles County.
Adjacent to the 100 acres is the AERA Energy Project that is comprised of about
3000 acres of which a substantial portion was under consideration to become a
future component of the City of Diamond Bar. At the City's request the consultant
working with LAFCO recommended that 2100 acres of the AERA project plus the
100 aforementioned acres become a part of the City of Diamond Bar. Tomorrow
morning the Local Agency Formation Commission (LAFCO) is being asked to
approve resolutions to place the 2200-acres into Diamond Bar sphere of influence.
There are a number of additional steps that would have to take place for the area to
become a part of the City. However, LAFCO's approval is essential for the City to
move forward to incorporate the property into the City of Diamond Bar.
Wi#h respect to the Code Enforcement issue about removal of trees at the end of
Crooked Creek PM/Fong reported that staff contacted a consultant to help the City
survey the damage and recammend mitigation. Staff is attempting to arrange a
meeting with Mr. Singh to discuss the damages and entice him to remedy the
situation. The piles of debris were removed.
Chair/McManus asked for an update on the burned out building on Pathfinder Road
west of the SR 57. PM/Fong said that the applicant had gone through plan check
and was close to obtaining the building permit.

CASE/FILE NUMBER Variance 2005-02
PROJECTLOCATION: 23929 Ridgeline Road
(Tract 30091, Lot 63)
Diamond Bar, CA 91765
APPLICATION REQLIEST: Approval to construct two geo-grid walls
with a maximum exposed height of 10
feet and 10 feet two inches in the rear
yard.
PROPERTYOWNER/.APPLICANT: Mr. and Mrs. Edward Layton
23929 Ridgeline Road
Diamond Bar, CA 91765
STAFF RECOMMEND�TION: Approve Variance No. 2005-02.
BACKGROUND:
The project site is located at 23929 Ridgeline Road (Lot 63, Tract No. 30091) within a
gated community identified as "The Country Estates". The project site is rectangular
shaped and descending in elevation toward the rear property line. According to the tract
map, the project site is approximately 1 .89 gross acres and has a flood hazard area with
a nati�iral drainage course located in the rear of the project site.
ANALYSIS:
During the February 2005 rain storm, the existing 1.5:1 rear slope that begins its descent
from the foundation of the existing residence failed. The slope failure was a mud flow of
fill and topsoil over bedrock. The failure has caused an unsafe condition at the project
site and to properties below the project site. As a result, the property owner of the subject
property desires to repair the slope before the rainy season begins. In order to repair the
slope, the property owner proposes two geo-grid walls to support and stabilize the slope.
The walls are proposed at exposed heights of ten feet and ten feet two inches with a
separation of fourteen feet between the walls. Between the residence and the first wall a
4:1 slope will be created and between the first and second wall a 2:1 slope will be
created.
Variance
Pursuant to Development Code Section 22.20, the maximum height of wall is six feet and
the Director may approve up to eight feet in the rear of a parcel due to topography. The
applicant needs walls with a maximum exposed height of ten feet two inches to repair the
slope failure and create slopes that are 2:1 or less in steepness as preferred in the City's
hillside managernent standards. As a result, a Variance approval by the Planning
Commission is required pursuant to Development Code Section 22.54.
"fhe staff is in support of the Variance approval due to the steepness of the slope and the
urgency to repair the slope because of the unsafe condition that exists at the project site.
Additionally, staff will require the applicant to submit a landscape/irrigation plan that will
delineate size, quantity, location and plant species that will assist in further stabilizing the
slope.
�vrxo�ai.�ssEssr�rr:
Pursuant to the provisions of the California Environmental Quality Act (CEQA), Section
15301 (restoration or rehabilitation of deteriorated or damaged to existing slope), the City
has determined that this project is Categorically Exempt.
VAR 2005�02 P��2
NOTICE OF PUBLIC H[EARING:
Notice for this project was published in the Inland Vallev Bulletin and the San Gabriel
Vallev Tribune on Ai�gust 12, 2005. Public hearing notices were mailed to approximately
32 property owners within a 500-foot radius of the project site and the public notice was
posted in three public places on August 11, 2005. Furthermore, the project site was
posted with a display board on August 11, 2005.

1
3. The Planr�ing Comrr�ission 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 cantained in
Section 753.5 (d) of Title 14 of the California Code of Regulations.
4. Based on the findings and conclusions set forth herein, thi�s Planning
Commission hereby finds as follows:
(a) The project relates to a site located at 23929 Ridgeline Road (Lot 63,
Tract IVo. 30091). 'fhe project site is rectangular shaped and
descending in eleva�tion toward �the rear property line. According to the
tract map, the project site is approximately 1.89 gross acres and has a
flood hazard area with a natural drainage course located in the rear of
�he project site.
(b) The project site has a General Plan land use designation Rural
Residential (RR).
(c) The project site is within the Single Family Residence-Minimum Lot Size
40,000 Square Feet(R-1-40,000)Zone interpreted as Rural Residential
(RR) Maximum 1 DU/Acre Zone.
(d) Generally, the following zone surroiands the project site: to �the north,
south east and west of the project site is the R-1-40,000 zone.
(e) The Application request is for approval to construct two geo-grid walls to
support and stabilize the existing rear slope. The walls are proposed at
exposed heights of ten feet and ten feet two inches with a separation of
fourteen feet between the walls. Between the residence and the first
wall a 4:1 slope will be created and between the first and second wall a
2:1 slope will be created.
Variance
(f) There are special circumstances applicable to the property(e.g., loca�tion,
shape, size, surroundings, topography, or other conditions), so that the
strict application of the City's Development Code denies the property
owner privileges enjoyed by other property owners in the vicinity and
under identical zoning districts or creates an unnecessary and non-self
created, hardship or unreasonable regulation which makes it obviously
impractical to require compliance with the development standards;
2
During the February 2005 rain storm, the existing 1.5:i rear slope that
begins its descent from the foundation of fhe existing residence failed.
The slope failure was a mud flow of fill and topsoil over bedrock. The
failure has caused an unsafe condition af the project site and to
properties below the project site. As a result, fhe property owner of the
subject property desires to repair the slope before the rainy season
begins. In order fo repair the slope, the property owner proposes two
geo-grid walis to support and stabrlize the slope. The wa/ls are proposed
at exposed heights of ten feet and ten feet two inches with a separation
of fourteen feet between the walis. Between the residence and fhe first
wall a 4:1 slope will be created and between the first and second wali a
2:1 slope wili be created.
Pursuant to Development Code Section 22.20, fhe maximum height of
wall is six feet and the Director may approve up to eight feet rn the rear
of a parcel due to fopography. The applicant needs walls with a
maximum exposed height of ten feet two inches to repair the slope
failure and create slopes fhat are 2:1 or less in sfeepness as preferred in
the City's hillside management sfandards. Therefore, special
circumstances applicable to the property are related to the sfeepness of
the existing slope (1.5:1) and urgency to repair the slope failure to
protect the subject property and the properties below. To create slopes
of 2:1 and 4:1, the strict application of the maximum wall heights would
deny the property owner fhe ability to repair the slope at a 2:1 grade or
less as preferred by the City's hillside management standards which
would profect the subject property and properties below.
(g) Granting the Variance is necessary for the preservation and enjoyment
of substantial property rights possessed by other property owners in the
same vicinity and zoning districts and denied to the property owner for
which the Variance is sought;
As referenced above in Item (f), granting the Variance is necessary for
the preservafion and enjoyment ofsubstanfial propertyrights possessed
by ofher property owners in the same vicinity and zoning districts. The
Variance is also necessary to ensure the safety of the owner of the
subject property as well as the owner of properties below the subject
site.
(h) Granting the Variance is consistent with the General Plan and any
applicable specific plan;
Due to the constraints of the project site related to the steepness of the
existing rear slope and urgency fo repair the slope as mentioned above
in Item (f), granting this Variance will be consistent with the General
Plan. The project area does not have a specific plan.
3
Y
(i) The proposed entitlement would not be detrimental to the public interest,
health, safety, convenience, or welfare of the City; and
The purpose of granting this Variance is to correct an unsafe condition
as referenced in ltem (f) above. However, prior to the issuance of any
City permits, the proposed project is required to comply with a!1
conditions within fhe approved resolution and the Building and Safety
Division and Public Works Division. The referenced divisions through
the plan check and permit and inspection process will ensure that the
proposed project is not detrimental to fhe public health, safety or welfare
or materiaJly injurious to the properties or improvements in the vicinity.
(j) The proposed entitlement has been reviewed in corripliance with the
provisions of the California Environmental Quality Act (CEQA).
Pursuant to the provisions of the California Environmental Quality Act
_ (CEQA), Section 15301, the City has determined that the project
identified above in this Resolufion is cafegorically exempt. Fur�hermore,
the categorica!exemption reflects the independent judgment of the City
of Diamond Bar.
