ADJOURNED REGULAR MEETING OF THE CITY OF DIAMOND BAR
JANUARY 9, 1995
CALL TO ORDER: MPT/Papen called the meeting to order at 6:10 p.m.
in the AQMD Auditorium, 21865 E. Copley Drive, Diamond Bar, California.
PLEDGE OF ALLEGIANCE: The audience was led in the Pledge of Allegiance by
C/Harmony.
ROLL CALL: Council Members Harmony, Miller, Werner and Mayor
Pro Tem Papen. Interim Mayor Ansari was excused.
Also present were Terrence L. Belanger, City Manager; Michael Montgomery, Interim City
Attorney; James DeStefano, Community Development Director, and Lynda Burgess, City
Clerk.
PUBLIC HEARING:
2.1 ADOPTION OF THE GENERAL PLAN - CM/Belanger stated that this was a first
in a series of public hearings to receive testimony on the draft General Plan and
introduced Don Cotton, Cotton/Beland Assoc., Inc. who served as a consultant to the
General Plan.
CDD/DeStefano reported that review of the General Plan would begin with the
Introduction, which contains the overall Vision Statement, and the Resource
Management Element, which contains the open space and conservation elements.
He explained that the Introduction generally discusses the purpose of the General
Plan, State requirements, history of the City and the community participation process
from the beginning of the General Plan development to the present. It outlines the
organization of the General Plan and describes the documents in detail. The most
important issue within the Introduction is the overall Vision Statement which is a
statement combining the hopes and aspirations of the community with the practicality
of preparing for the social, economical and physical needs of the citizens. The
Vision Statement is the beginning point of the General Plan and serves as a means
of defining the overall scope and emphasis of the General Plan. The Resource
Management Element is comprised of the State -mandated Open Space and
Conservation Elements. The Open Space Element is required pursuant to
Government Code and details plans and measures for preserving open space for
natural resources, the managed production of resources, and active and passive
recreational areas. The Conservation Element, pursuant to Government Code,
addresses conservation, development and use of natural resources, including trees,
water, soil visual features and mineral deposits. Resource Management issues
include open space, visual resources, biological resources and parks and recreation.
D.B. is known as a master planned community developed upon, within and adjacent
to hillside slopes and ridges providing a distinctive visual identity for the City. A
portion of the City's sphere of influence contains a "Significant Ecological Area" due
to the extensive stands of riparian, oak and walnut woodland. The City and its sphere
of influence contain several areas with identified biological resources. Pressure for
development of the remaining vacant land combined with the desire to maintain the
JANUARY 9, 1995 PAGE 2
existing environment necessitates a careful balance of development and preservation
policy. The City needs to determine which areas of open space (including those with
biological or visual resources) should be preserved and what means to use to assure
their protection. There exists a number of recreational opportunities within the
region available to residents. Over 470 acres of identified public and private
recreational facilities have been developed within the City. However, of the 135
acres owned by the City, only 59 acres is developed for the community's 54,500
residents. Although school sites are utilized for a portion of the residents'
recreational needs, City-wide, there is a significant deficiency in active parkland to
support the existing and future population of the City. The National Park &
Recreation Assn. standard of 5 acres of parkland per 1,000 residents means that the
City should currently have approximately 272 acres of developed parkland and
ultimately require 285 acres to support a buildout population of 57,000 residents.
Policy issues incorporate the need to plan for the growing demands of local residents
through the utilization of existing facilities and the necessity to plan for additional
recreational facilities. The General Plan Advisory Committee (GPAC) and the
Planning Commission reviewed the Introduction and Resource Management
Element. Changes to the former General Plan are identified within the text of the
Plan. GPAC's recommended changes were reviewed by the Planning Commission.
The Planning Commission made one major change to the Vision Statement. GPAC
indicated its primary goal was that the community retain its "Country Living"
character. The Planning Commission indicated they felt it was not the primary point
of reference for the community's Vision Statement, but a part of the six points of the
overall Vision Statement. The Commission recommended adoption of the
Introduction and Resource Management Element as presented. He further
recommended that Council review the material, receive public testimony, review the
Introduction and Vision Statement and then the Resource Element. At the conclusion
of the meeting, the Council should continue the Public Hearing to Monday, January
16, 1995.
C/Werner asked for identification of the second undeveloped park referred to in the
Introductory Comments, Section III -2, Parks and Recreation.
CDD/DeStefano stated that in addition to Pantera Park, the second undeveloped park
is Larkstone Park, a 2.8 acre site at Larkstone and South Pointe Middle School.
C/Werner indicated he would later suggest an update to reflect the current conditions.
MPT/Papen confirmed that GPAC and Planning Commission requested Council to
acknowledge, as it has since 1992, the State's park recommendation of 5 acres per
1,000 people, or 272 acres. She reiterated CDD/DeStefano's comment that the City
has a deficiency, and the introduction statement indicates the City is inadequately
served by active and passive park facilities. However, on Table 111. 1, 261.8 acres of
developed recreational facilities are indicated. If the City's goal is 5 acres per
thousand or 272 acres and if buildout is 285 acres, subtracting 261.8 current acres,
JANUARY 9, 1995 PAGE 3
this leaves 23.2 remaining to be developed. Pantera Park is 23 acres, and with this
development, it appears the City is .2 acres short of meeting the standard. In
addition, the City has 200 acres of passive undeveloped land according to the table.
She asked staff to respond.
CDD/DeStefano stated that Table III.1 identifies existing recreational facilities and
incorporates the golf course, the Little League field and "The Country" Park. The
issue is that those facilities are not available to the general public. The issue within
the General Plan is one of providing active recreational facilities to meet today's
needs and the needs of future residents. The concern is that while these private
facilities may fulfill some of the needs, there is no ownership or ability to program
activities by the City. Private facilities may fulfill some of the needs, there is no
ownership or ability to program activities by the City. Therefore, the General Plan
looks to provide sufficient acreage for the active recreational needs of the residents.
MPT/Papen suggested separating publicly -owned recreational facilities. It appears
that privately -owned and publicly -owned facilities are combined in one paragraph,
and in the next, they are separate.
C/Werner agreed with MPT/Papen. He expressed concern with the statement added
by the Planning Commission indicating "any measure." He asked that the statement
"by any measure the City is inadequately served" be stricken and in its place add
"there are X acres of private and X acres of public" and let the policy section deal
with any of the inadequacies.
MPT/Papen declared the Public Hearing open.
Wilbur Smith, 21630 Fairwind Ln., stated that the Vision Statement that GPAC
suggested was stricken by the Planning Commission. He indicated that the most
fundamental part of the process is the citizen's vision of the City which has always
been a rural and country living environment. To see it stricken by the Planning
Commission was very discouraging and it tended to diminish the entire effort of
GPAC. In his opinion, the Planning Commission was not a direct representation of
the community. He referred to Page 9 indicating there should be clarification that
Tonner Canyon is only one of several solutions to the traffic problem through the
City. He then requested that document 2 and 3 be included in the review process.
MPT/Papen asked Mr. Smith to define "rural."
Mr. Smith defined "rural" by open space, hills, vegetation and contour. Clearly in
the south end and eastern part of the City, there is a rural atmosphere.
Gary Neely, 344 Canoe Cove Dr., indicated on Page 10 of the Introduction, under
Public Services and Facilities Element, it might be better to state "at a later date, as
a General Plan amendment, a separate Economic Development Element will
JANUARY 9, 1995 PAGE 4
be submitted." Under Circulation, Page 10, "Physical Mobility" should be deleted
and the list under Issues should include "Automobile Transportation; Transit and
Paratransit Services; Truck Routes; Railroad Lines; Bicycle Routes; Equestrian
Trails; and Aviation." With respect to the Resource Management Element: Page
III -11, Strategy 1.3.2, delete "use suitable." Page III -12, Strategy 1.3.9, delete "or
agricultural." Page III -18, Objective 2.6, Strategies 2.6.1 and 2.6.2, "will be
prepared" and "will be developed" are redundant since this is what the General Plan
accomplishes.
Responding to C/Werner, Mr. Neely stated the specificity with respect to "untreated
potable water" was because GPAC was concerned about a "blank check" approach
in the absence of a professional definition of "reclaimed water." The City of Industry
hired Boyle Engineering to compile the report which contains the verbiage "untreated
potable water."
In response to MPT/Papen, Mr. Neely confirmed he believed one of the strategies
should be "the City will work with the property owners of neighboring jurisdictions
to complete a fresh water (not chlorinated) reservoir that could be used for
recreational purposes." This is the recommendation of GPAC and Planning
Commission for the upper Tres Hermanos property. In addition, "agricultural uses"
should be eliminated because they don't work together.
Max Maxwell, 3211 Bent Twig, asked if and when the meeting would be
rebroadcast. Referring to the July 9, 1992 Implementation Mitigation Monitoring
Program, he stated it had never been discussed publicly. He asked if this is a legal
part of the General Plan and who authored the document. With respect to the
Introduction, he supported the statement "It is the primary goal of the City to
maintain a rural and country living environment."
Barbara Beach-Courchesne, 2021 Peaceful Hills Rd., believed the Introduction
captures the hopes of the majority of citizens. She requested the Council to seriously
consider the concepts set forth in the Introduction and review the remainder of the
document for both real and perceived compliance with the ideals set forth.
Martha Bruske asked the Council to consider distinguishing parks not available for
public use and excluding them from the list of parks.
Wilbur Smith stated that during GPAC meetings, he made several attempts to have
a statement included in the General Plan which would cause developers to include
a park or play area within developments. Referring to Page III -2, 1. and Page 5 of
the Introduction, one statement indicates D.B. is a master -planned community and
another statement indicates it really is not. He suggested on Page III -2 under 2.
Biological Resources, second paragraph, fifth line, the sentence beginning "Tonner
Canyon supports a diverse population of native animals" should include "deer." On
page III -12, he requested the Council to define the source of the water.
JANUARY 9, 1995 PAGE 5
Terry Birrell believed that the following areas of the Resource Management Element
must be revised in order to be in compliance with California Codes, and for the
General Plan to have the integrity which comes from internal consistency. The
existing inventory of local recreational facilities on Page III -3 and III -4 excludes all
areas designated as "open space" in the Land Use Element. Table III -1 should be
amended to include an inventory, name and open space acreage for the following
areas: Sandstone Canyon, approximately 100 acres; the open space south of Grand
Avenue; and the former water district, approximately 4 acres. Larkstone Park
(Facility 10) should be asterisked. She indicated it is somewhat misleading to have
it scheduled since it is not being maintained as a City park and has been allowed to
be taken over by the school district. The County has a right to take the acreage away
from the City because it is not being maintained for the use for which it was deeded
over. Second, the prior Council very clearly redesignated large tracts of open space
as planned development in prior General Plans. In her opinion, this plan is much less
straight forward. The Planning Commission applied approximately 300 acres of
open space between Grand Ave. and D.B. Blvd. Regarding agricultural land in the
Agricultural/Specific Plan, she questioned what guidance the General Plan gives
future owners, developers, planning staff and citizens. She indicated her preference
for the Grand Ave./Diamond Bar Blvd. area would be "open space." Third, she
suggested adding Strategy 1.2.6 to Page III -11 as follows: "Join with neighboring
cities to incorporate open space land within the City of D.B. into a wildlife corridor."
Finally, with respect to Strategy 1.11, development of a Tree Ordinance should
stipulate at least the following five species of trees: Oak, Black Walnut, Riparian/
Royal Willow, Sycamore and Pepper Tree. GPAC's provision that a natural
vegetation preservation ordinance be developed and adopted is crucial to
maintenance of hillsides and wildlife.
Max Maxwell supported the statements made by Terry Birrell and indicated that he
wanted "open space" to include Tonner Canyon without the specific plan designation.
With respect to Resource Management, he asked for a statement to read: "Preserve
Tonner Canyon, upper Sycamore Canyon, Sandstone Canyon and all those areas that
have restrictions." GPAC requested separation of parks from open space. On Page
III -7, 3. Parks and Recreation, Issue Analysis was totally misinterpreted. The
statement should read: "There is a need to protect influence..." Regarding the Tree
Ordinance, Mr. Maxwell asked the Council to direct the Planning Commission to
move quickly to provide a Tree Ordinance. With respect to the Hillside Management
Ordinance, slope density should be included.
Barbara Beach-Courchesne stated that Government Code 65560 requires an Open
Space Element in the General Plan. She would like to see more specificity in the
General Plan as to how the City will implement the concepts. Regarding III -10,
1.1.11, Tree Ordinance, the chapter refers to preserving and the Planning
Commission deleted all reference to "how" and "what." She feels it is crucial the
"how" and "what" be stated within the document. Also on Page II -10, 1.2.2 and Page
III -11, 1.2.4 and 1.2.5, the strategies listed are incompatible with the development
JANUARY 9, 1995 PAGE 6
permits the City continue to approve to date. Regarding Page III -14, 2.2.1 she
questioned whether the City has resources to meet this goal and strategy.
David Schey, Parks & Recreation Commission, referred to notes forwarded to the
Council stating the intent of the Resource Management Element was to create a
greater emphasis within the Element of the need to expand and utilize parks and
recreational facilities the City has and to develop new parks and recreational
facilities. Under the existing conditions, the City's facilities are interim use, and it
would be a fallacy to view these facilities as a permanent recreational asset. With
respect to the other items in the Resource Management Element, he stated that there
is an emphasis to expand existing facilities and integrate the open space preservation
function into the needs assessment and parks master plan. He suggested a definitive
analysis of the available open space resources be completed in order to determine
how best to deal with them.
With no further testimony being offered, MPT/Papen closed the Public Hearing.
RECESS: MPT/Papen recessed the meeting at 7:32 p.m.
RECONVENE: MPT/Papen reconvened the meeting at 7:40 p.m.
2.1 ADOPTION OF THE GENERAL PLAN (CONT'D.) - C/Harmony moved,
C/Werner seconded to reinsert the first sentence of the Vision Statement, which read:
"It is the primary goal of the City of Diamond Bar to maintain a rural and country
living environment."
C/Werner stated that he does not view rural and country living as a primary goal.
C/Miller agreed with C/Werner.
MPT/Papen stated that in her opinion "rural" means a minimum of five acre lots,
gravel roads, horses and cows and bicycles travelling on the same roads, hikers
avoiding cow pies, no electricity, no plumbing. The Chamber of Commerce deleted
"country living" from its logo about eight years ago and added in its place
"dynamic." The City is, with an average of three to six units per acre, at least in her
opinion, D.B. has not been rural since the first developments.
C/Harmony stated the debate over rural living is a point of controversy. Country
living conveys a sense that the open spaces are going to remain open. GPAC said the
first statement should reflect what the community symbolizes.
C/Werner withdrew his second his second to the motion.
MPT/Papen indicated that Page 1, A. Vision Statement, second bullet, preservation
of open space resources, second sentence of the second paragraph, should be changed
JANUARY 9, 1995 PAGE 7
to read: "SEA 15 is considered to be a major significant ecological asset to the
community."
C/Harmony requested ICA/Montgomery to respond to the concept of "taking."
ICA/Montgomery answered if the use is not changed from that currently devoted, it
is not a "taking."
MPT/Papen noted C/Harmony's objection to the change.
C/Werner indicated that on Page 10, Public Services and Facilities Element, a
separate Economic Plan should be stated. Under Circulation, strike "Physical
Mobility" and include the other transit options covered.
In response to MPT/Papen, CDD/DeStefano stated that staff could add a one -or -two
word description of the issues in the element.
Responding to C/Werner, CDD/DeStefano indicated that the Mitigation Monitoring
Program was incorporated as part of the 1992 draft General Plan's Environmental
Impact Report. The second draft General Plan incorporated an addendum to the EIR
and an amendment to Mitigation Monitoring Program and this General Plan would
do likewise.
MPT/Papen asked if there is further reason for Public Hearing with respect to the
Mitigation Monitoring Program.
CDD/DeStefano stated that the Mitigation Monitoring Program was amended as a
result of the amendment to the EIR which does not require a Public Hearing.
Council reviewed the documents in 1992 and 1993 which were included in the
resolutions which the Council ultimately adopted.
Responding to C/Werner, CDD/DeStefano stated that the environmental documents
were not challenged, but the General Plan was. There are two components to the
document being referenced, the first component is implementation and the second is
the Mitigation Monitoring Program where the strategies, goals and objectives are
listed and responsible parties are stated and time frames for completing given tasks
are indicated. That can be referenced as a document contained within the
Environmental Impact Report technical appendices. It could be added to the list of
General Plan format and documents on page 11.
MPT/Papen suggested that on Page III -2, first sentence under 1. Open Space and
Visual Resources, delete "master planned."
C/Miller suggested that page III -2, Item 2, Biological Resources, include "deer" and
"several species of mice" so that the sentence reads: "Tonner Canyon supports a
JANUARY 9, 1995 PAGE 8
diverse population of native animals, including the California ground squirrel,
cottontail rabbit, coyote, deer and several species of mice." The next sentence should
read: "The canyon habitat may also support other animals such as the endangered
Stephen's kangaroo rat, and possibly the California Gnatcatcher."
With respect to Page III -2, 3 Parks & Recreation, C/Miller stated he agrees with
C/Werner that "By any measure" should be deleted from the second sentence so that
it reads: "The City is inadequately served by active and passive facilities" and adopt
Mr. Schey's proposed language for the balance of the paragraph. On Page III -7, C,
Resource Management Issues, 1. Open Space and Visual Resources, the Parks &
Recreation Commission requested the Council redefine the issue analysis so that the
statement reads: "There is a need to preserve open space within the City and the
sphere of influence and to utilize portions of these preserved open spaces for parks
and recreational uses."
C/Werner suggested adding "...where feasible and safe."
C/Miller suggested striking "inadequately" on Page III -7, C. Resource Management
Issues, 3, Parks & Recreation.
Council agreed to strike the second sentence, Page III -2, 3, Parks & Recreation.
Returning to Page III -7, C, Resource Management Issues, 3. Parks and Recreation,
Council agreed to strike the first sentence under Issue Analysis and change the
balance of the statement to read: "There is a need to plan for additional parks and
recreational facilities to serve the growing needs of local residents through full
utilization of existing facilities within City boundaries and with the surrounding area;
additional recreation parklands are necessary to meet the community needs."
On Page III -9, Goal 1, C/Werner suggested changing the sentence to read:
"Consistent with the Vision Statement, create and maintain an open space system
which will preserve scenic beauty, protect important biological resources, provide
open space for outdoor recreation and the enjoyment of nature, conserve natural
resources, and protect public health and safety." On Page III -10, adopt the Parks &
Recreation Commission's recommended change so the strategy reads: "Expeditiously
develop and adopt a tree ordinance designed to retain and/or replace native trees
within the City."
In response to C/Werner, Mr. Schey responded that native trees includes the trees
previously listed in the General Plan.
C/Miller suggested, under Strategy 1.1.5, Page III -9, "significant vegetation" be
changed to "natural vegetation" so the strategy reads: "When deemed necessary by
the City, require that natural vegetation be preserved or transplanted, as determined
by a qualified biota report approved by the City."
JANUARY 9, 1995 PAGE 9
C/Werner suggested that Page III -10, Strategy 1.1.11 be changed to read:
"Expeditiously develop and adopt a tree ordinance designed to retain and/or replace
native trees within the City."
C/Miller recommended on Page III -9, Strategy 1. 1.4 be changed to read: "Preserve
to the maximum extent feasible existing vegetation within undeveloped hillside
areas."
C/Werner suggested Page III -9, Strategy 1.1.5 be changed to read: "When deemed
necessary by the City, require that significant vegetation be preserved or transplanted
as determined by a qualified biota report approved by the City."
C/Werner moved, C/Miller seconded to approve the Introduction as revised and
directed staff to make it available for public review by Thursday, January 12, 1995,
so that it can be completed in final form ready for adoption as an agenda item 30
days after it is available to the public. Motion carried unanimously.
MPT/Papen announced that the Council would conclude with Page III -10 of the
Resource Management Element and continue deliberation of the Element to January
16, 1995 at 6:00 p.m.

A motion was made by MPT/Papen to adopt the Parks & Recreation Commission's
suggested renumbering and rewording of strategies 1.3.1. through 1. 3.9 including
deletion of "agricultural" in 1.3.9. Motion seconded by C/Werner with the following
amendment: With respect to Objective 1.3, delete the "s" on "meets" so that the
Objective reads: "Maintain a system of recreation facilities and open space
JANUARY 16, 1995 PAGE 2
preservation which meet the active and passive recreational needs of Diamond Bar
residents of all ages." Motion carried unanimously.
With respect to Goal 2, Page III -12, C/Werner suggested changing the statement to
read "Consistent with the Vision Statement, identify limits on the resources needed
to support existing and future uses within the City of Diamond Bar and its sphere of
influence, and ensure that resources are used wisely."
Council directed staff to come back with appropriate language for Page III -13,
Strategy 2. 1.1 a., prior to the close of the Council meeting.
At the request of Council, Mr. Neely stated that Strategy 2.1.1 d. on Page III -13
discusses "a 144 -acre lake" which was described in a conceptual specific plan that
the City and City of Industry commissioned. There are two proposed lakes, one for
reclaimed water which is entirely within the borders of the City on the 800 acres of
Tres Hermanos Ranch. The second is an untreated potable water lake which has the
potential of having boundaries within the City. However, the vast majority would
be located in San Bernardino County.
C/Wemer asked if staff knows what the City of Industry intends with regard to these
policies.
CM/Belanger stated that the proposed untreated potable water lake is in the southern
two-thirds of the Tres Hermanos Ranch which is located in the City of Chino Hills.
Chino Hills General Plan, recently adopted, does not include provisions for such a
facility. The area has a low density residential designation. With respect to the City
of Industry, staff would need to contact them to determine if there continues to be an
interest in locating the lower reservoir.
C/Miller suggested Strategy 2.1.1 d. be changed to read "Monitor the City of
Industry's plans to locate reclaimed water facilities within the Tres Hermanos Ranch
area."
MPT/Papen suggested Strategy 2.1.1 b. be changed to read "Work with the local
water agencies and schools to promote public education regarding conservation and
advantages for reuse of water." She addressed the potential for the City taking over
management of the water agency serving the Walnut Valley. The City covers 60%
of the use area and the City, through vote of the people, could assume management
of the Walnut Valley Water District. As elected officials, the Council supports the
use of reclaimed water. However, the management of the water agency has failed to
implement those programs, and has acted to the contrary when new development has
been taken before the agency to pursue a direction on reclaimed water for irrigation
purposes. The opportunity has been denied and the agency has stated the facility will
not be built in the next 10 years. Some months ago, she requested the City and the
Water District to hold a joint meeting to discuss these policies and instruct
JANUARY 16, 1995 PAGE 3
management teams of both agencies to implement the same policy.
C/Harmony stated he was not convinced that the Walnut Valley Water District had
been unresponsive to recycled water usage. He referred to a capital improvement
budget prepared by the City wherein the City itemized a reclaimed water facility that
the City would manage for $17,000,000. He felt this, or any provision thereof, does
not belong in the General Plan.
C/Werner suggested Strategy 2.1.2 should read: "Prepare ordinances that allow for
the implementation of feasible water conservation technologies into new
developments such as, but not necessarily limited to:..." because technologies will
continue to change.
In response to IM/Ansari, CDD/DeStefano concurred with the comments made by
C/Werner. It is a list of strategies and implementation measures that are designed to
encourage water conservation. Since this is a 17-20 year General Plan, the intent is
to deal with these issues over time as technology changes.
CM/Belanger stated that the General Plan anticipates that one of the major
implementation mechanisms will be the Zoning Ordinance in the Development Code,
as well as other related ordinances.
In response to C/Miller, CDD/DeStefano stated that the current Water Efficient
Landscaping Ordinance discourages installation of large areas of lawn or turf in
commercial and industrial areas. It exempts single family residential neighborhoods.
C/Werner recommended that the objective be consistent with State law.
CDD/DeStefano suggested under Strategy 2.1.3, Page III -13, add at the beginning
of the sentence: "Consistent with State law."
MPT/Papen indicated that the Parks and Recreation Commission requested the
Council add to Strategy 2.1.3 "in private as well as, public facility developments."
Council agreed that the Strategy 2.1.3 should be amended to "Consistent with State
law, encourage the use of primarily drought -tolerant plans, efficient design in
landscape application, and the use of reclaimed water systems."
CM/Belanger offered the following language for Strategy 2. 1.1 a. "In cooperation
with adjacent communities and water purveyors, encourage the use of reclaimed
water; consider the construction of duel water systems, where feasible, for new
development." Council concurred.
Council recommended deletion of Strategy 2.1.3 d.
JANUARY 16, 1995 PAGE 4
Council recommended replacing the wording on Strategy 2.1.5, Page III -14 with the
Parks and Recreation Commission suggested wording as follows: "Establish the City
as a leader in the implementation of water conservation measures through
expeditious implementation of the measures outlined above."
MPT/Papen suggested eliminating the second bullet under Strategy 2.2.2, Page
III -14. Council concurred.
Regarding Page III -14, Strategy 2.2.2, C/Wemer suggested changing Strategy 2.2.2,
Page III -14 to read "in conjunction with review of development applications,
encourage incorporation of the following:..." Council concurred.
Responding to MPT/Papen, C/Werner suggested Strategy 2.2.6, Page III -15 be
changed to read: "Encourage, with the use of available financial incentives,
provisions for solar energy systems for the heating of swimming pools." Council
concurred.
MPT/Papen suggested replacing the wording in Strategy 2.2.3, page III -15 with the
wording of the third bullet under Strategy 2.2.2 on Page III -4. Council concurred.
Regarding Page III -18, MPT/Papen indicated that, during Public Comments, it was
suggested that Objective 2.6 is confusing and should be stricken in its entirety.
C/Werner suggested that it should be deleted and replaced with the Open Space
Inventory.
ICA/Montgomery stated Government Code requires that cities identify all open space
lands, public and private, that the City determines what should be dedicated to:
Future natural resource preservation; managed production preservation; recreational
preservation; or, public safety preservation. The parcel and the use for which it
should be held or dedicated to, must be identified. The City is required to have an
active Open Space Management Plan within the General Plan. A General Plan that
does not aggressively speak to open space, and provide a program for the open space,
is legally defective.
MPT/Papen suggested that Council instruct staff to prepare a list of all privately and
publicly held dedicated open space for incorporation into the General Plan.
CM/Belanger stated that the Land Use Map will indicate the designations for each
tract of land within the City. Those that are designated as open space would need to
be a part of that inventoried list.
CDD/DeStefano stated that the General Plan has, for several years, contained a list
of vacant property. It is contained within appendices to the Environmental Impact
Report. What needs to be incorporated in the General Plan is the ultimate use of all
JANUARY 16, 1995 PAGE 5
of the property within the City, whether if be for development or for open space, no
development purposes-- the specific list of those properties that would have an Open
Space designation, all of which will be consistent with the requirements of the
Government Code.
Council directed staff to insert the language of Objective 2.6 and its Strategies
currently on Page III -18, within the Introduction to the Resource Management
beginning on Page I.1.
With respect to Table III -1 on Page III -4, MPT/Papen recommended a column be
added for "Equestrian Facilities." The subtotal should be re-identified as
"City -owned Recreational Facilities." In addition, three categories should be listed
under "Other Facilities:" 1) "Public Facilities owned by the City of Diamond Bar",
2) "Other Public Facilities", 3) "Privately Owned Recreational Facilities."
C/Werner requested a footnote to indicate the reversion provision in the deed for the
property held by the Little League.
MPT/Papen suggested the deed should be researched to make certain the reverter
clause exits. Council concurred.
Responding to C/Werner, CDD/DeStefano recommended the General Plan
incorporate The Country Park in Table III -1.
MPT/Papen suggested a separation of tables. Table III -1 should include "City -owned
Public Facilities" and a second table, Table III -2, include "Private and Other
Facilities not owned by the City of Diamond Bar," for informational purposes.
Council concurred.
RECESS: IM/Ansari recessed the meeting at 7:22 p.m.
RECONVENE: IM/Ansari reconvened the meeting at 7:40 p.m.
2.1 GENERAL PLAN PUBLIC HEARING (CONT'D.) - C/Harmony asked why the
Council is not itemizing Tonner Canyon, Sandstone Canyon, and upper Sycamore
Canyon on the list of Open Space Recreational Facilities.
CDD/DeStefano responded that he could not recall why they were not listed and that
he would look into the matter and bring it back to Council at the next meeting.
MPT/Papen stated that she didn't understand C/Harmony's statement. These items
would properly be listed on the Open Space Inventory, not on a Recreational
Facilities table since it is not, nor has it ever been, their dedicated use.
Responding to C/Harmony, C/Miller suggested deleting "The Country Park" from
JANUARY 16, 1995 PAGE 6
Table III -1. Council concurred.
C/Werner moved, C/Miller seconded to direct staff to make the corrections to the
Resource Management Element of the General Plan as discussed, bring the revisions
back, make them available to the public for at least 30 days, after which, schedule the
Resource Management Element for adoption. With the following Roll Call vote,
motion carried:
AYES: COUNCIL MEMBERS - Miller, Werner, MPT/Papen, IM/Ansari
NOES: COUNCIL MEMBERS - Harmony
ABSENT: COUNCIL MEMBERS - None
CDD/DeStefano presented the Public Services and Facilities Element and indicated
that this Element is optional. It is a creation of the City and not required by
California State Code. It incorporates issues related to public services and facilities
and financing for them and crosses over several other Elements within the General
Plan; in particular, Land Use, Resource Management and the Public Health and
Safety Element. The Public Services and Facilities Element discusses a number of
policy issues dealing with existing levels of service and development of community
facilities. Infrastructure addresses joint use of facilities and financing. Within the
Master Environmental Assessment, there is a wide variety of information dealing
with library services, school services, police, fire, etc. which is useful foundation
material for this Element. Both the Planning Commission and General Plan
Advisory Committee reviewed the Element and the changes are noted. He
recommended that the Council open the public hearing, receive testimony on the
Public Services and Facilities Element, review the Element and direct staff to make
the desired revisions.
IM/Ansari declared the Public Hearing open.
Gary Neely, 344 Canoecove Dr., offered comment on four strategies: 1.1.5 a.,
former 1.1.5 b.; 1.4.2 and 2.1.2 in a memo to the City Council via on-line. He
indicated the change of wording on Strategy 1.1.5 a. is for consistency with the
strategy in the Resource Management Element. Strategy 1. 1.5 b. is for consistency
with the third bullet under the last paragraph on Page VI -1. With respect to Strategy
2.1.2, his preference would be to modify this strategy to primarily support a change
in legislative philosophy regarding funding of local governments so that primarily,
city governments are financed through the use of property taxes.
Wilbur Smith, referring to Page VI -2, second sentence, first paragraph, stated he
observed a number of engineering services acquired from outside agencies. He felt
the General Plan should discuss how outside services are acquired. He recommended
under Section D, Page VI -4, that Strategy 1.1.5 a. specifically identify the plan.
Under 1.1.5 c, GPAC added the previously deleted statement "Oppose applications
for proposed waste treatment facilities within Diamond Bar and surrounding
JANUARY 16, 1995 PAGE 7
communities" in an attempt to oppose the MRF. The new statement softened that
statement to the degree that, under certain conditions, allow the MRF. On Page VI -5,
Objective 1.3, he objected to the word "ensure." Strategy 1.3.1 implies it may be
necessary for the City to come up with money if it wants to support and pursue
development of major joint recreational facilities. If this is the intent, he asked
Council to consider the fiscal aspect. He also felt "ensure" should be changed in
Objective 1.4. Under Strategy 1.4.2, identify the plan, if there is a plan. Since the
University of California has no plans to locate a campus in D.B., so the statement
should be eliminated. He indicated he would like to have Strategy 1.5.3 include play
areas for children. He requested the Council add verbiage to identify the "model" in
Strategy 2.1.4. He felt 2.3.3 does not fit.
C/Harmony asked Mr. Smith how Strategy 1.1.5 b. under Goal 1 relates to the MRF.
Mr. Smith responded that if this does not refer to the MRF, he is not opposed to the
Strategy.
Max Maxwell, referring to Page VI -6, 2. 1.1 asked Council to clarify the change and
a definition for Strategy 2.1.3. He objected to the method of adopting each Element
separately and asked the City Attorney to comment.
With no further testimony being offered, IM/Ansari closed the Public Hearing.
Responding to Mr. Maxwell and C/Werner, ICA/Montgomery stated that the time for
challenge is not "ripe" unless and until the entire General Plan's formal Resolution
has been adopted by the Council. The Council may adopt each Element by minute
action on the way to the final adoption.
CM/Belanger stated that the issue related to adoption of each separate Element is an
internal consistency issue since each Element may have on effect on any or all other
Elements.
Don Cotton, Cotton/Beland, suggested that prior to adopting any Element of the
General Plan, the Council should certify the EIR addendum. Then the Council may
adopt any of the Elements.
In response to Council, CM/Belanger indicated that a sentence would be added to the
first paragraph, Page VI -2 to indicate the approximate number of lots that currently
utilize on-site wastewater disposal systems.
MPT/Papen, referring to paragraph 7, Page VI -2, asked that "also" and "very small"
be stricken so the sentence reads "The Los Angeles County Library System maintains
a community library on Grand Avenue near Diamond Bar Boulevard." Council
concurred.
JANUARY 16, 1995 PAGE 8
MPT/Papen asked that the "Foothill Transit System" be added to the last sentence,
Page VI -2 so that it reads: "Other services within Diamond Bar include branch office
postal services administered in Pomona, MTA bus system, Foothill Transit system
Walnut -Diamond Bar YMCA, and Seniors organization." Council concurred.
C/Miller recommended deleting "although the statewide drought makes the
long-term supply of water to this area questionable" from the final sentence,
paragraph 8, Page VI -2 so the sentence reads: "Water facilities are generally
adequate." Council concurred.
C/Harmony recommended that the third sentence, first paragraph, Page VI -3 be
stricken. Council concurred.
C/Harmony asked for elaboration of the second sentence, second paragraph, page
VI -3 with respect to discussions with Orange County.
CM/Belanger responded that the logical flow of a sewer system in the southerly
sphere of influence would be south, rather than pumping back up the hill. Therefore,
it would end up in Orange County. Because this is pure conjecture, a more specific
answer should come from the Engineering Department.
C/Werner requested that Council direct staff to restate the paragraph to reflect the
conditions outlined by CM/Belanger and brought back in the final text for approval.
MPT/Papen recommended revision of the first two sentences of the third paragraph,
Page VI -3 to reflect the current conditions since the City is part of the County Flood
Control System.
CM/Belanger responded that much of the Flood Control System lies within the City's
Public Facilities streets. He suggested that further clarification is warranted and that
staff treat this paragraph the same as the prior paragraph and return to Council with
further clarification.
MPT/Papen suggested deleting "continuation of the" from the first sentence, seventh
paragraph, Page VI -3, so the sentence reads "Although local water purveyors can
adequately serve the area in terms of facilities, a Statewide drought could put severe
restrictions on the availability of water." The Council concurred.
Regarding Page VI -4, the following changes were recommended:
C/Werner asked that "Consistent with the Vision Statement," be added to the
beginning of the sentence following D. GOALS, OBJECTIVES AND
IMPLEMENTATION STRATEGIES, so that the sentence reads: "CONSISTENT
WITH THE VISION STATEMENT, IT IS THE OVERALL GOAL OF THE PLAN
THAT THE CITY ACQUIRE AND MAINTAIN ADEQUATE RESOURCES TO
JANUARY 16, 1995 PAGE 9
MEET THE NEEDS OF ITS RESIDENTS." Council concurred.
Citing Mr. Neely's suggestion and Mr. Smith's concern, MPT/Papen suggested
Strategy 1.1.5 a. be consistent with Strategy 1.3.9 on Page II -12. Council concurred.
With respect to Strategy 1.1.2, CDD/DeStefano suggested staff return with revised
language meeting the intent of the Council.
MPT/Papen suggested staff come up with language for Strategies 1.1.2, 1.1.3 and
1.1.4 deleting the word "Ensure." Council concurred.
CDD/DeStefano stated Strategy 1.1.5 b. was related to the MRF at both the GPAC
and Planning Commission levels. Council directed staff to rewrite Strategy 1.1.5 b.
MPT/Papen suggested staff reword Objectives 1.3 and 1.4 on Page VI -5 on Page
VI -5 deleting the word "Ensure."
Council directed staff to reword Strategy 1.1.6, Page VI -5.
C/Miller reminded Council of his recommendation to not meet on Planning
Commission meeting nights. Council agreed to meet on the 1 st and 3rd Mondays
and the 2nd and 4th Tuesdays.

2. PUBLIC HEARING:
PUBLIC SERVICES AND FACILITIES ELEMENT
2.1 ADOPTION OF THE GENERAL PLAN - Regarding the Public Services and
Facilities Element, M/Papen referred the Council to proposed wording of Strategies
1.1.2, 1.1.3 and 1.1.4, Page VI -4 provided by staff. In addition, due to his absence,
MPT/Werner submitted written recommendations for changes to this Element.
CDD/DeStefano recommended language as follows for Strategy 1.1.2: "Protect
existing residents and businesses from the cost of financing infrastructure aimed at
supporting new development or the intensification of development." Without
objection, Council concurred.
With respect to Strategy 1.1.3, CDD/DeStefano suggested "Require the construction
of water, sewer, drainage and other necessary public facilities prior to or concurrent
with each new development." Without objection, Council concurred.
Regarding 1.1.4, CDD/DeStefano suggested "Require the project sponsor to provide
all necessary infrastructure improvements including the pro -rata share of
system -wide improvements." Without objection, Council concurred.
CDD/DeStefano continued to page VI -4, Strategy 1.1.5b suggesting the following
language: "Support the development of appropriately -sited, environmentally
sensitive, solid waste treatment facilities which do not impact residents' quality of
life." Without objection, Council concurred.
Referencing Strategy 1.1.6, Page VI -5, CDD/DeStefano suggested "Require that all
new subdivisions be connected to a public sewage system." Without objection,
Council concurred.
Suggested wording for Objective 1.2, Page VI -5, from MPT/Werner: "Establish and
implement solutions to the financing of public facilities and services which best
JANUARY 24 , 1995 PAGE 2
protect the interests of the taxpayer." Without objection, Council concurred.
Regarding Strategy 1.2.1, the following was suggested by MPT/Werner: "Establish
a development fee structure which best assures that costs for new capital facilities
and expansion of existing facilities necessitated by the approval of new development
or intensification of existing development are funded by the proponents or
beneficiaries of projects in proportion to the demand created by the development."
Without objection, Council concurred.
With respect to Strategy 1.2.2, MPT/Werner proposed "Investigate and, if feasible,
initiate the establishment of a redevelopment agency in the City of Diamond Bar to
facilitate the mitigation of traffic and circulation deficiencies, the financing of public
improvements and other similar tasks." Without objection, Council concurred.
With respect to Objective 1.3, Page VI -5, CDD/DeStefano recommended "Provide
residents with access to high quality local educational facilities." Without objection,
Council concurred.
The following language was suggested by MPT/Werner for a new Strategy 1.3.4,
Page VI -5: "Enable, through appropriate zoning, development regulations, or with
a Conditional Use Permit, the construction and operation of private school
facilities." Without objection, Council concurred.
In response to M/Papen, CDD/DeStefano stated that Objective 1.5 and all
sub -strategies was originally a component of the Land Use Element. The Planning
Commission recommended that it be moved from the Land Use Element to the
Public Services and Facilities Element. This Objective and attached Strategies
attempts to achieve a hierarchy of social gathering places for the community, both
on private and public lands.
M/Papen suggested the following language for Strategy 1.5.1, Page VI -6: "Retain
and provide community social gathering places, including active and natural park
lands and one or more community centers. In private commercial and office
complexes, encourage the development of plaza areas." Without objection, Council
concurred.
With respect to Strategy 1.5.2a., MPT/Werner recommended deleting the words "and
firmly fix the event(s) in the mind of the public" so the Strategy reads: "Whenever
possible, establish permanent locations and regular dates for community events to
improve attendance." Without objection, Council concurred.
Regarding Strategy 1.5.3, MPT/Werner suggested incorporating the addition of
"park" proposed by Wilbur Smith as "Within new residential developments,
encourage organization of individual neighborhoods and discourage through traffic
on local streets while maintaining pedestrian and bicycle continuity and encourage
JANUARY 24 , 1995 PAGE 3
neighborhood parks, improvement programs and social events." Without objection,
Council concurred.
With respect to Goal 2, Page VI -6, MPT/Werner recommended "Consistent with the
Vision Statement" so that the goal reads "Consistent with the Vision Statement,
achieve a fiscally solvent, financially stable community." Without objection,
Council concurred.
Regarding Objective 2. 1, Page VI -6, MPT/Werner suggested deleting "ensure
adequate" and replace it with "maximize" so that it reads "Provide sufficient
opportunities for retail and other nonresidential commercial and office uses as
necessary to maximize municipal income to finance desired community amenities."
Without objection, Council concurred.
Council adopted, without objection, Mr. Neely's recommended language for Strategy
2.1.2, Page VI -6 "Work with State officials and local elected representatives to make
a determined effort to promote statewide legislation that would secure guaranteed,
long-term stable financing of local government based upon primarily property tax
revenues. Alternatively, support legislation that would redistribute sales tax revenues
to local agencies based upon an equitable formula that would include both the
location where the sales tax revenue was collected and the population of each local
agency involved."
MPT/Werner suggested the following language to replace Strategy 2.1.4: "Utilize
public cost/benefit and/or fiscal impact analyses in the review of new development
proposals and in determining acceptability." Without objection, Council concurred.
In response to M/Papen, CM/Belanger suggested with respect to Strategy 2.2.1,
"Conduct a periodic review of user charges, development fees and public facilities
impact mitigation fees in accordance with California Government Code Section
66000 et al, (AB 1600) to ensure that the charges are consistent with the costs of
improvement and maintenance, and that public services and facilities are being
expanded in a cost-effective manner."
Regarding Objective 2.3, VI -7, MPT/Werner suggested "Promote public and private
services and amenities to the community." Without objection, Council concurred.
M/Papen concluded deliberation on the Public Services and Facilities Element and
requested that the two remaining revisions on Page VI -3, paragraphs 2 and 3 be
deliberated at the January 30, 1995 Council meeting.
PUBLIC HEALTH AND SAFETY ELEMENT
Regarding the Public Health and Safety Element, CDD/DeStefano reported that the
Element establishes policies and programs to protect the community from risks
JANUARY 24 , 1995 PAGE 4
associated with seismic, geologic, flood and fire hazards. It is comprised of two
State required elements: 1) the Noise Element, which has been required of the City's
General Plan since 1971. The Noise Element incorporates issues related to existing
noise, environment, sources of noise, and the impacts of noise upon residents. The
Element identifies the sources, existing and projected levels of noise, and methods
of attenuation. Major noise issues for D.B. revolve around the desire to prohibit new
development from adversely affecting existing land uses. Strategies have been put
in place to ensure that future developments incorporate noise studies to identify and
mitigate all noise impacts. In regard to the second State required component 2) The
Safety Element has been required by law since 1976. This element requires cities to
identify potential safety hazards and adopt policies related to the protection of people
and property from fire, flooding, geologic and seismic hazards. The City's local
relevant safety issues include the need to protect residents from the hazards identified
and ensure that appropriate levels of public safety personnel services and facilities
are provided. He recommended that the Council receive a brief supplemental
presentation from Pat Mann, CottonBeland Associates, Inc., regarding the Noise
Element, open the Public Hearing and receive testimony, review the Element and
continue the Public Hearing to the next meeting.
Mr. Mann discussed how noise is measured, how noise standards are set and how
most noise experienced by communities comes from transportation sources.
Although most noise complaints come from people's behavior, this is not something
the General Plan attempts to address. The General Plan is mainly concerned with
the compatibility of land uses in areas exposed to noise. In order to practically
regulate the technical aspects of noise, an attempt is made to reduce the noise
environment to a single measurement value. In order to assist the Council, he
referred to State and National guidelines for land uses.
M/Papen declared the Public Hearing open.
Don Schad, 1824 Shaded Wood Rd., stated that the level at Peterson Park
occasionally exceeds 100 decimals. He felt this is very damaging to the children
over a prolonged period of time. In addition, he indicated he has recorded decibel
levels of 80 inside the homes at peak hours along the easterly hill along the SR 57
north of Pathfinder Rd. and south of the SR 60.
C/Miller asked Mr. Schad how the City should deal with a table and noise standards
within the General Plan knowing that the noise levels at the proposed high school
and other locations will far exceed the acceptable levels.
Mr. Schad suggested one method could be the architecture and development of the
proposed buildings. Other buffer zones might be created using a form of zigzag
walls.
Max Maxwell, 3211 Bent Twig Ln., agreed with Mr. Schad that the noise levels
JANUARY 24, 1995 PAGE 5
should be kept low. He asked the Council to consider the impact of noise levels on
the enjoyment of neighborhood yards.
Wilbur Smith, 21630 Fairwind Ln., stated, with respect to Page IV -4, c., Public
Health and Safety issues 1, Geology and Seismicity, the comments should be greatly
expanded upon. He further stated there is not sufficient attention given to geology
under Goal 1, Page IV -7. He asked the Council to address the concerns of excessive
water and the dynamic geologic conditions as a single item.
There being no further testimony offered, M/Papen closed the Public Hearing.
Responding to Mr. Smith, M/Papen stated the Development Code would address the
specifics.
Regarding IV -2, M/Papen and C/Ansari suggested that the second paragraph under
1, Geology and Seismicity, be changed to read "There are existing historical
landslides and potential unstable hillside areas in Diamond Bar."
C/Miller recommended the last sentence, paragraph 1 under 3, Fire Protection
Services, Page IV -3 be changed to "The sphere of influence area adjacent to Tonner
Canyon does not presently have (or need) these same levels of protection."
In response to M/Papen, CM/Belanger stated staff would provide all fire station
numbers in the second sentence, paragraph 2 under 3, Fire Protection Services.
In accordance with Mr. Schad's wishes, C/Miller recommended that the fourth
sentence, first paragraph under 8, Noise, Page IV -4 be stricken.
Responding to Council regarding the ambiguity of paragraph 2 under 8, Noise, Page
IV -4, CDD/DeStefano recommended the Council give staff an opportunity to
indicate, through text and graphics, the concerns of the Council.
CM/Belanger indicated staff may create Page IV -14 to incorporate the document to
include the foundation for this information.
M/Papen suggested under 8, Noise, Page IV -6, Issue Analysis, that "rural lifestyle"
be changed to "quality of life" to read "Emphasizing its important on quality of life,
the City needs clear policies on how it will keep noise, primarily from major
roadways, from impacting existing as well as future residents." Without objections,
Council concurred.
Per MPT/Werner's wishes, M/Papen recommended changing Goal 1, Page IV -7 to
read "Consistent with the Vision Statement, create a secure public environment
which minimizes potential loss of life and property damage, as well as social,
economic or environmental disruption resulting from natural and manmade
JANUARY 24, 1995 PAGE 6
disasters." Without objection, Council concurred.
C/Miller recommended changing Strategy 1.2.1, Page IV -7, to read "Where
applicable, as a prerequisite to new development or the intensification of existing
development, ensure that a drainage study has been completed by a qualified
engineer, certifying that the proposed development will be adequately protected, and
that implementation of the development proposal will not create new downstream
flood hazards." Without objection, Council concurred.
Regarding Objective 1.2, M/Papen recommended striking "eliminate" and
"minimize" and move "minimize" to the beginning of the sentence so that it reads
"Minimize the potential for loss of life, physical injury, property damage, public
health hazards and nuisances from the effects of a 100 -year storm and associated
flooding." Without objection, Council concurred.
Responding to M/Papen, CM/Belanger suggested the first sentence of Strategy 1.8.1,
Page IV -9 be changed to "Coordinate with the established Los Angeles County
Program for household hazardous waste collection according to the provision of
Section 41500 of the Public Resources Code (see also the solid waste section of the
Plan for Resource Management for additional policies)."
In response to C/Miller, CM/Belanger recommended Strategy 1.5.1, Page IV -8 be
reworded as follows: "Refer proposals for new development and, where appropriate,
for the intensification of existing development to the Sheriffs Department for
review."
With respect to Strategy 1.10.5, Page IV -11, add "Prior to occupancy" at the
beginning of the last sentence so that it reads: "Prior to occupancy, if the required
level of mitigation is not achieved, further corrective action will be required."
M/Papen recommended that Strategy 1.10.11, Page IV -11 be stricken. Mr. Mann
agreed.
C/Miller moved, C/Ansari seconded, based upon M/Papen's request, that the Public
Services and Facilities Element be amended as proposed, released to the community

MEETING DATE: February 6, 1995
TO: Honorable Mayor and Members of the City Council
FROM: Terrence L. Belanger, City Manager
SUBJECT: Adoption of the General Plan
ISSUE STATEMENT: State law requires the preparation and adoption of a comprehensive, long
term General Plan for the physical development of all property within the
City and any land outside its boundaries which bears relation to its
planning. Upon adoption, the General Plan, through its numerous goals,
objectives and strategies, will define development strategy for the next
twenty years.
BACKGROUND:
On October 17, 1994 the Planning Commission recommended approval and adoption of the Draft General
Plan. The City Council began its review of the documents on January 9, 1995. The Council has
examined the Introduction, Vision Statement, Resource Management Element (RME), Public Services
and Facilities Element (PSFE), and the Public Health and Safety Element (PHSE). The purpose of the
February 6, 1995 continued public hearing is to review City Council comments on the Noise Standards
Table and to continue review of the Circulation Element.
DISCUSSION:
Revisions to the Public Health and Safety Element
The City Council requested further information regarding the Noise Standards Table found on page IV -12
of the PHSE. Our General Plan consultant has prepared the attached response to City Council comments
for consideration. Staff has provided a copy of the previously distributed Noise Standards Table for
reference.
1
Review of the Circulation Element
On January 31, 1995 the City Council began its review of the Circulation Element. The Council received
a presentation from the City staff and invited public testimony. The Council reviewed the Element and
requested further information and several modifications to the text, tables and figures. In response staff
has prepared the attached revised Element for consideration. Staff has reorganized the contents of the
Element by repositioning the text, tables and figures. Council comments suggesting a reduction of the
document bulk have been addressed. As an example, Table V-3 addresses existing and future average
daily traffic volume for our freeways and many local streets. The technical information represented by
Table V-3 was originally a part of the Master Environmental Assessment (MEA). The reorganized
Element moves this table back to the MEA where such technical information is more appropriately
placed.
Additional revisions respond to the comments related to the need for the inclusion of a regional map and
clarification of issue statements and Strategy 1.1.4. Staff revisions are identified by italics with an
indicator located in the left side margin. Attached is a copy of the staff revised Circulation Element.
Staff has provided an additional copy of the Traffic and Transportation Commissions alternative
Circulation Element. In June of 1994 the General Plan Advisory Committee reviewed the Circulation
Element and provided the Planning Commission with their recommendations. An alternative version of
the Element was presented to the Traffic and Transportation Commission by Mr. Gary Neely in July
1994. The Planning Commission conducted its noticed public hearings on the Circulation Element and
concluded by incorporating portions of T&T text. The attached T&T document is annotated to indicate
the location of its information within the Planning Commission recommended Circulation Element or the
MEA.
The City Engineer will provide the City Council with a presentation on the staff revisions to the
Circulation Element. Please reference the previously distributed Master Environmental Assessment,
specifically Section II- T, the Final Environmental Impact Report, and the OPR Guidelines contained
within the Reference Material Handbook.
RECOMMENDATION:
It is recommended that the City Council discuss appropriate revisions to the Noise Standards Table or
related text, receive a presentation from City staff on the Circulation Element (CE), review the Element
and continue the public hearing.

TratlBmlttliig: Response to City Council Comments on Noise Standards Table
Remuka: The following responses are provided to City Council comments and concerns
raised at the Council meeting January 31, 1995. I have included a summary of
my oral responses which were made at the meeting.
1. The revised table includes standards for laid uses where exterior noise
standards were not included in the previous table which was adopted by
the Planning Commission.
Response. Exterior noise standards for libraries and hospitals did not appear
in the table approved by the Planning Commission. Such standards west
included in the revised table by CBA based on state and federal guidelines for
planning in noise impact areas. These standards reflect the feasibility and
practicality of providing an acceptable interior noise environment for these
uses in high -noise environments. If desired by the Council, those standards
may be eliminAteid to make this table fully consistent with the previous table
approved by the Planning Commission.
2. The table limits our}kxibility to allow uses in areas that are already
exposed to high noise levels.
Responm It is our recommendation that the City not permit residential uses
or school classrooms or playgrounds in areas exposed to noise above 75 dB
CNEL unless noise is mitigated by barriers which reduce the noise on the site
to less than that level. 75 dB CNEL, the noise level above which residential
uses and schools are considered "Clearly Unacceptable" is an extremely high
noise level which would be found only directly adjacent to heavily traveled
freeways and under airport approach or departure patterns at commercial
airports within two miles or so of the ends of the runway. Thost areas should
not be used for residential development or schools under any circurnstances.

James DeStdoo, Febmty 1, 1886, pare I
Sound barriers or other methods must be used to protect schools and
residences from such nigh noise levels, or the land should be used for other
purposes. Public testimony that traffic noise levels of 100 dB(A) or more
have been measured on residential sites and within residences, if accurate, can
only refer to peak noise levels lasdag for at most a few seconds from
unusually loud noise events. This cannot be directly related to the 24-hour
average levels used in these noise standards without more information about
the nature and frequency of these noise events. B takes nearly five minutes of
daytime noise at 100 dB(A) to produce a 24-hour average noise level of 75 dB
CNEL.
3. We are proposing parks which include both active and passive areas
within the same area - why ars the standards dt flerent?
Response. The Planning Commission considered that quiet, passive
recreation functions could not be carried on in outdoor area where the noise
level exceeds 65 dB CNEL, and therefore that areas exposed to such noise
levels would not be usable for and should not be designed for such activities.
I concur with that assessment. Passive, quiet recreation functions should be
placed in areas where the noise level from other sources is less than 65 dB
C:'NEL. In designing parks, these areas should be placed farther from public
streets than active areas, or in area shielded by terrain from freeway noise.
4. Why are noise levels for outdoor uses such as school playgrounds and
active recreation areas lower than those for indoor uses?
Response. The noise level considered "Clearly Unacceptable" for outdoor
activity areas was based on public health standards documented by the U.S.
Environmental Protection Agency in its document Report on Levels of
Environnumlal Noise Requisite to Protect the Public Health and Weifare with
an Adequate Margin of Sq Eery published in response to the requirements of the
Noise Control Act. This document identified i noise level of 70 dB Ley as
sufficient to result in permanent hearing damage with continuous exposure. It
is our recommmendation that the public not be intentionally exposed to noise
levels substantially higher than that in areas intended for outdoor recreational
activities. The 75 dB CNEL standard is intended to provide such protection.
Interior activities are protected by stvcturos from these high noise levels, and
therefore can tolerate a higher noise level outdoors.
5. Should we be calling this "Noise Standards" or use a lens regulatory
title?
Response. The language of the interpretive section of the table indicates that

these are guidelines subject to interpretation. None of the descriptions
indicate that the standards aro absolute. A more descriptive title for the table
may be "Development Guidelines for Noise Impact Areas"
6. Does the inclusion of this table require retrofitting of existing land uses
where the stawuhv* in the table are not now met?
Response. No. The language of the table refers to "new development" or
'development" in each of the acceptability categories. While the table
indicates where existing problemt may exist, it does not indicate how these
existing problems should be dealt with. policy 1.10.7 indicates that the policy
is to encourage, where possible, reduction of existing noise problems within
existing development, but does not require retro ting.
Isn't 65-75 dB CNEL too loud for yard areas in residential areas?
Response. Noise levels above 65 dB CNEL should be considered undesirable
for outdoor living. partly for this reason, residential use is considered
"NormallyU'nacceptable" in these noise zones. However, because a very large
area of Diamond Bar is exposed to such noise levels from freeway and arterial
street traffic, it may be desirable in some casae to permit residential
development as the best among the choices of uses for this land.
In such areas, residential use should be permitted only with careful study of
the noise environment and the needs of the development. The table provides
for such review in these areas. Depending on the layout of the site, shielding
of the yard by berms, walls or the house itself may provide a suitable
environment for outdoor living.

The Community Noise Equivalent Level (CNEL) and Day -Night Noise Level (Ldn) are measures of the 24-hour
noise environment. They represent the constant A -weighted noise level that would be measured if all the sound
energy received over the day were averaged. In order to account for the greater sensitivity of people to noise at
night, the CNEL weighting includes a 5 -decibel penalty on noise between 7:00 p.m. and 10:00 p.m. and a
10 -decibel penalty on noise between 10:00 p.m. and 7:00 a.m. of the next day. The Ldn includes only the
10 -decibel weighting for late-night noise events. For practical purposes, the two measures are equivalent for
typical urban noise environments.

v' Intrusion of Through Traffic on the streets of Diamond Bar consists of motorists who
live, work and shop in the City of Diamond Bar plus motorists who are passing through the
City but do not stop for any roason. The alignment of the City's three most significant
arterial streets:; Diamond Bar Boulevard, Golden Springs Road and Grand Avenue results
in significantly large volumes of through traffic which is fed from the 57 (Orange) Freeway
and the 60 (Pomona) Freeway.
Currently, Dduring peak commute periods, congestion is heavily concentratedheavy along
the 57 (eight lanes of traffic) and 60 (eight lanes of traffic) Freeways, particularly through
tho ono mile long soction of frooway within Diamond Sar where the 57 Frooway
andcorrorponds with the 60 Freeways join together for a one -mile long reduced cooridor of
no more than 6 -lanes of traffic, and in the segment of the 60 Freeway immediately east of
the 57 Freeway whore the capacity of the 60 Frooway is reduced to jthree travel lanes in
each direction). Congestion is particularly heavy during AM and PM peak traffic hours -and
has resulted in tremendous volumes of traffic utilizing Diamond Bar Boulevard. Grand
Avenue and Golden Springs Drive as freeway bypasses.
FREEWAY BYPASSES
Diamond Bar Boulevard has becomeis-an attractive alternative route, primarily
due to interchanges with the freeway at both the southem and northern sections of
the City. Diamond Bar Boulevard intersects with the 57 Freeway south of the
merge, and at the northern divergence of the 57 Freeway and the 60 Freeway. In
addition, it serves as a shortcut to traffic traveling to or from San Bernardino County
via Grand Avenue. These factors result in a tremendouslarge intrusion of
commuter traffic using Diamond Bar Boulevard to travel between areas to the south
of the City and jurisdictions north and east of Diamond Bar.
Golden Springs Drive is also utilized as an alternative route for avoiding the
congested segment of combined freeway. During AM peak traffic, the route is
utilized by traffic traveling west from the 60 Freeway and southbound on the 57
Freeway towards the westbound 60 Freeway corridor west of the City. The
Diamond Bar Boulevard exit is used to access Golden Springs Drive. with traffic
continuing west on Golden Springs Drive/Colima Road eventually reentering the
westbound 60 Freeway beyond the point of congestion. The same route is also
used during PM peak traffic with traffic exiting the eastbound 60 Freeway at either
the Azusa Avenue, Fullerton Road, Nogales Street exits in Rowland Heights or the
Brea Canyon Road exit in Diamond Bar, and re-entering either the eastbound 60
Freeway or the northbound 57 Freeway at Diamond Bar Boulevard.
Grand Avenue is currently the only east -west route which directly serves the
developing central Chino Hills area. Although the 60 Freeway is accessible to the
north, heavy congestion along this freeway makes Grand Avenue an attractive
route, for vehicular traffic traveling between the Chino Hills area of San Bernardino
County and areas west of Diamond Bar along the 60 Freeway corridor towards Los
Diamond Bar General Plan Circulation Element
October 17, 1994 Planning Commission Recommendations 1-1
Angeles as well as south of the City along the 57 Freeway corridor towards northern
Orange County.
In February of 1994, The City of Chino Hills documented that 50% of the working adults in
their Csity of 48,000 residents (16,286 households) commute to work in Los Angeles
County, 30% commute to work in Orange County and only 20% commute to work in San
Bernardino or Riverside Counties. The City of Chino Hills General Plan currently allows
for an additional 10,529 households (a 65% increase to total nearly 80,000 residents in
26,815 households) upon that city's build -out.
To quantify the magnitude of through traffic in the Diamond BarG#y, a license plate survey
was conducted' . A discussion of this study's methodology and the complete results of the
analysis is contained in the Master Environmental Assessment document.
The results from this analysis confirmed the three principal arterial routes within the City to
have significant percentages of their total traffic volumes comprised of vehicles making
through trips. Most of the through trips during the PM peak flow period occurred on
Diamond Bar Boulevard, Golden Springs Road and Grand Avenue and were observed
exiting the City into San Bernardino County along Grand Avenue. In fact, Grand Avenue
east of Diamond Bar Boulevard is the arterial segment experiencing the largest volumes of
through trip traffic within the City.
Due to the extremely poor operating conditions and significant delays experienced at the
intersection of Diamond Bar Boulevard and Grand Avenue during PM peak periods (V/C
1.26, LOS F), local and collector streets within residential areas adjacent to this
intersection are often utilized by commuter traffic to bypass the heavily congested
intersection.
Residents report intrusion of cut -through traffic on Montefino Avenue, Quail Summit Drive,
Rolling Knoll Road, Mountain Laurel Way, Silver Rain Drive, Meadow Glen Drive, Carpio
Drive, Armitos Place, Leyland Drive, Summitridge Drive, Longview Drive, Gold Rush Drive
and Palomino Drive. Intrusion of through traffic into residential neighborhoods has caused
several problems, including speeding, increased vehicle/vehicle and vehicle/pedestrian
accidents? excessive road wear and tear, and increased traffic noise in residential
neighborhoods, particularly in the vicinity of schools.
D. GOALS, OBJECTIVES AND STRATEGIES
"IT IS THE OVERALL GOAL OF THE PLAN TO PROVIDE A SAFE, ADEQUATE
AND ENVIRONMENTALLY SENSITIVE TRANSPORTATION SYSTEM TO
MEET THE
CIRCULATION NEEDS OF THE CITIZENS OF DIAMOND BAR."
GOAL 1 "Consistent with the Vision Statement. eEnhance the environment
of the City's street network. Work toward improving the problems presented
Diamond Bar General Plan Circulation Element
October 17, 1994 Planning Commission Recommendations 1-2
by the intrusion of regionally oriented commuter traffic through the City and
into residential neighborhoods. Consider programs to reinforce the regional
transportation and circulation system to adequately accommodate regional
needs."
Objective 1.1 Participate in local and regional transportation related planning and
decision-making.
Because Diamond Bar is under flight paths from both Ontario and Los Angeles
International Airports, and PRoximiTY to major freeways tends to increase the number of
helicopter overflights, the City should remain vigilant to air traffic increases and seek
regulations to relieve noise and air pollution.
Strategies:
1.1.1 Preclude the connection of roadways from adjacent jurisdictions into
the City unless demonstrable benefits to Diamond Bar residents and businesses are
indicated.
1.1.2 In reviewing transportation improvements, maintain a clear distinction
between local and regional objectives.
1.1.3 Ensure the opportunity for public comment on major changes in
operational characteristics of the circulation system.
1.1.4 Proactively work with adjacent jurisdictions to determine acceptable
alternate travel corridors around the City of Diamond Bar and Sphere of Influence. Such
considerations will incorporate no major road through Tonner Canyon, recognize
environmental sensitivity and avoid disruption of SEA 15.
1.1.5 Continue to seek support for Regional State Transportation
Improvement Program (RSTIP) projects as proposed by the City of Diamond Bar such as:
(a) Encourage modification of the SR57/SR60 interchange;
(b) Support construction of HOV lanes on SR60, from SR57 north
to San Bernardino County;
(c) Support construction of HOV lanes on SR60, from Brea
Canyon Road to SR57 north;
(d) Support construction of HOV lanes on SR57, from Orange
County to SR60; and
(e) Pursue additional Park & Ride facilities east of the City.
1.1.6 Encourage Orange and San Bernardino Counties to fund and
construct an environmentally sensitive transportation corridor roadway through Soquel
Canyon and or Carbon Canyon.
Diamond Bar General Plan Circulation Element
October 17, 1994 Planning Commission Recommendations 1-3
1.1.7 The City should encourage the efforts of other jurisdictions and
agencies to complete the work on other circulation projects outside of Diamond Bar that will
positively effect Diamond Bar's traffic conditions. These projects include:
(a) completion of SR -30
(b) Upgrade of SR -71 to freeway standards
(c) The construction of Soquel Canyon Road extension to SR -57
(d) Development of additional lanes on SR60 easterly of the City.
(e) Improve the capacity of State Route 142, Carbon Canyon
Road
1.1.8 Coordinate the use of land use policies from neighboring communities
and incorporate all existing traffic data including improvements and proposal for the
regional circulation system.
1.1.9 Encourage improvements to regional routes and arterial streets to
be sensitive to environmental, aesthetic and noise concems and provide adequate
buffers to adjacent land uses.
1.1.10 Through the use of the provisions of Califomia Health and Safety
Code. Division 24, Parts 1, 1.5 and 1.7. pursue a coordinated effort with the City of
Industry and the State of Califomia to widen the one mile stretch of freeway carrying the
57 and 60 freeways., and upgrade the interchanges of Brea Canyon/60 Freeway. Grand
Avenue/60857 Freeways and Diamond Bar Boulevard at the 57 Freeway (north and
south): and the widening of Golden Springs Drive.

V. CIRCULATION ELEMENT
A. INTRODUCTION
The purpose of the Circulation Element is to define the transportation needs of the City and present a
comprehensive transportation plan to accommodate those needs. The focus of this plan element is the
identification and evaluation of local circulation needs of the City of Diamond Bar, balancing those needs with
regional demands and mandates. It has been developed to guide the orderly improvement of the circulation
system within the City in a manner which will protect the quality of life which is Diamond Bar and in direct
response to the City's Land Use Element.
The overall intent of the Circulation Element is to provide safe and efficient movement between homes and
jobs, stores, schools or parks within the City. Under State planning law, each city must develop and adopt
a comprehensive long-term general plan for the physical development of that city. The following is a
mandatory requirement relating to city transportation planning:
Government Code Section 6530M): A circulation element consisting of the general location and
extent of existing and proposed major thoroughfares, transportation routes, terminals, and other local
public utilities and facilities, all correlated with the land use element of the plan.
This is the first circulation element prepared for the City of Diamond Bar. Although it is a new city, it is not
a newly developing city, but rather one that is largely built out. Many strategic decisions related to
transportation facilities (e.g., locations of roadways) were made at the County level prior to City
incorporation. This circulation element provides the first opportunity to evaluate how best to utilize these
facilities, from the perspective of the City of Diamond Bar, its residents, businesses, and other users of City
services.
Five basic steps were involved in developing the Circulation Element. The first step consisted of documenting
existing conditions and assembing a factual data base. The second step involved the development and
validation of a transportation model used to forecast future travel demand and travel patterns withinthe City
and the surrounding area Step three entailed identification of problems, opportunities and issues. The fourth
step was the evaluation of alternative improvement scenarios. The fifih and final step comprised the definition
and refinement of the Circulation Element.
The resulting document is organized into the following sections with each of the above components of the
circulation system being discussed, where appropriate, therein.
• Circulation System
• Major Circulation Issues
• Goals, Objectives and Strategies
Technical Appendices to the Master Environmental Assessment document support this section and contain
additional details and analysis of existing and future conditions, travel forecast model documentation, and the
Congestion Management Plan.
The Circulation Element also has direct relationship with the Housing, Resource Management, Public Health
and Safety and Public Services and Facilities Elements.

The components of the circulation system in the City of Diamond Bar include the following:
• Streets and Highways
• Transit and Paratransit Services
• Railroads
• Bicycle, Him LjU and Equestrian Facilities
• Aviation
• Goods Movement
Bash of thwe are dareribod below: This section describes each of the components, discusses opkrating
conditions and evalutates the adequacy of the component.
1. Streets and Highways
a. Functional Classification, definitions WJ J=
The two major considerations in classifying the City's street network functionally are access to adjacent
properties and movement of persons and goods into and through the City. City streets are classified by the
relative importance of these two functions assigned to them. The classification of streets is essentially a
determination of the degree to which access functions are to be emphasized at the cost of the efficiency of
movement or discouraged to improve the movement function. The design and operation of each street,
therefore, depends upon the importance placed on each of these functions. For example, streets designed to
carry large volumes of vehicles into and through the City have more lanes, higher speed limits, and fewer
driveways, while residential streets have fewer lanes, lower speed limits, and more driveways to provide
access to fronting properties.
The functional classification system allows the residents and elected officials to identify preferred
characteristics of each street. If observed characteristics of any street change from the functional
classification, then actions can be taken to return the street to its originally intended use or to change the
designated classification. For example, if traffic volumes and speeds on a residential street exceed expected
levels, then measures can be implemented which are designed to lower traffic volumes and reduce speeds.
Under the Circulation Element of the County of Los Angeles, roadways within Diamond Bar were categorized
into four functional classification types,. Tie 2U 2CD1ansoi%d BRdefing,gwr funcvionel akissificwtion Ww
9f roadi►vvs is follows:
• Freeways
• Arterial Streets (Major and Secondary)
• Collector Streets (Business and Residential)
• Local Residential Streets
The City has adopted these functional classifications for its roadway network Future V-1 depicts the regional
roadway system as it presently exists in the City.

Freeways generally provide inter -regional access. Their primary function is to move vehicles through or
around the City, thus, there is not access to adjacent land, and limited access to arterial streets. Freeways
contain anywhere from 4 to 12 lanes with recommended design volumes from 80,000 to 210,000 vehicles per
day.
Arterial streets carry the majority of traffic entering or traveling through the City. A "major" arterial has

Arterials serve two primary functions: to move vehicles into and through the City, and to serve adjacent
commercial land uses. Driveways and other curb cuts along arterial are generally linriied designed to
minimize disruption to traffic flow.
Collector Streets are intended to carry traffic between the arterial street network and local streets or directly

factors. The maximum volume of 2,500 is, therefore, to be used as a guide only, as siOvity t4 the
neighborhood and its impect needs to be carefully considered,
Local residential streets include those streets predominantly residential in terms of adjacent property use, and
are intended to retain a residential character. They are typically not designated in the General Plan Circulation
Element.
Table V-1 identifies roadway classifications for key roadways in the City along with right-of-way guidelines.
Typical street sections are maintained as part of the City's design guidelines. Current typical street sections
are included in the technical appendices.
b. Level of Service Standards
Level of service standards define the desirable traffic volumes on City streets in relation to the capacity of
those streets. The City has utilized level of service standards in the traffic analysis work for the General Plan,
and these are summarized in the EIR. The City should continue to use such standards, maintaining and
updating them when necessary to be consistent with current prevailing standards in the
}� region and requirements such as the statewide Congestion Management Program. T.;4 V-2 presents

C. Roadway Systems
The efficiency of a roadways operation is generally evaluated in the industry by volume -to -capacity ratios.
this ratio compares the Average Daily Traffic volume to the roadways capacity. Levels of Service (LOS) are
identified based on the calculated ratio. Table V-3 provides a description of the various levels of service to
be used as the City's guidelines for analyzing the efficiency of street operation.
Speed information regarding:
• Current levels of service
• Estimated existing and future average daily volumes by street segment
• AM/PM peak hour traffic levels of service be street segment
• Map of signalized intersections
• A description of the methodology and data used to establish baseline information and current
conditions
is contained in the Master Environmental Assessment and technical attachments.
A major concern of the City of Diamond Bar is the operating efficiency of its streets. Based upon an analysis
performed in 1991, traffic projections for the future (year 2010) indicate that up to 26 local street segments
may experience a level of service of E or F. This undesirable condition is the result of the intrusion of
regional traffic through Diamond Bar.
a The City proposes to proactively pursue activities which will enhance the use of it's infrastructure for Diamond
Bar residents. In addition, the City will work wda neighboring jurisdictions to mitigate their effects on the
Iota steet system due to the intrusion of regional traffic.
d. Transportation Corridors
A key issue related to traffic circulation is how current street infrastructures will be used and what future
improvements may be considered to mitigate traffic congestion.

To this end, the Ory of Diamond Bar intends to:
• Monitor, coordinate, idents, and advocate improvements or moderations to the existing
infrastructure which will provide for the best use of our roadway system for the movement of
traffic
• Encourage and initiate ongoing e„f°orrs to work with neighboring cities to analyze, assess and
evaluate alternate by-pass corridors through such areas as Carbon, Soquel and Tonner
Canyon.
The City also believes that if a by-pass corridor is identified for a roadway, it should be considered using
environmentally sensitive methods of evaluation.

A Excellent operation. All approaches to the intersection appear 0- .60
quite open, turning movements are easily made, and nearly all

B Very good operation. Many drivers begin to feel somewhat .61 - .70

utilized and traffic queues start to form.
C Good operation. Occasionally drivers may have to wait more .71 -.80

vehicles. Most drivers feel somewhat restricted.
D Fair operation. Cars are sometimes required to wait more than .81 - .90
60 seconds during short peaks. there are no long-standing

practice for peak period.
E Poor operation. Some long-standing vehicular queues develop .91 - 1.00
on critical approaches to intersections. Delays may be up to
several minutes.
F Forced Flow. Represents jammed conditions. Backups from Over 1.00

cause the facility to have minimal impact to the environment and adjacent ecosystem. It also meets the general
prerequisites of being able to allow for movements of people and goods in a safe and efficient manner. These
characteristics should include but not be limited to the following:
topographic — the corridor should blend with the natural terrain as much as possible to reduce
grading and movement of earth. Curves and contours of the natural terrain should be reflected in
design of the corridor. This goal must necessarily be balanced with providing safe corridor geometry
for the modes of travel that will use it.
hydrology -- positive drainage control will be developed as part of the corridor design to provide for
capture and transmission of runoff from the facility to an appropriate storm drainage facility. This
goal is to control foreign and potentially incompatible fluids and panicles from entering the adjacent
ecosystem
air quality — street sweeping/cleaning shall be programmed into maintenance operations to prevent
buildup of dirt and dust on the corridor travel surface. This goal will serve to reduce the amount of
airborne particulates which could otherwise enter the adjacent ecosystem Alternative fuel vehicles
and small vehicles should be encouraged rather than trucks to further improve air quality along the
corridor.
noise — to the extent possible, modes of travel should be encouraged which have reduced sound
characteristics. In addition, natural barriers to sound created by the corridor should be developed
and implemented to reduce sound intrusion into the adjacent ecosystem. Consider controlled speed
limits to reduce noise impacts.
corridor — a corridor should be defined as a route that encourages movement of people in a manner
that encourages multimodal uses such as buses, trolleys and shuttles; discourages single occupant
vehicle trips. Movement of goods within this corridor should be evaluated in terms of not detracting
from the basic goal of maximizing movement of people in high occupancy vehicles. Restriction on
vehicle type and weight may be considered as part of the corridor. Creative tra k management
techniques should be encouraged (such as reversible lane operation) to take bust advantage of
roadway cross-section and minimize impacts to the corridor area.
biological habitat -- replant and maintain natural plant species to the extent possible along the
corridor where grading has altered the natural landscape. Similarly, provide frequent game crossings
to permit natural migratorypaths to be maintained. Consider designation of the corridor for daylight
use only.
aesthetic — views from the corridor should reinforce the feeling in the traveler that they are in an
environmentally sensitive area. Similarly, views of the corridor from adjacent properties should
reinforce the feeling that the corridor is a natural part of the landscape. Corridor structures, as
necessary, should be a natural part of the terrain.
By nature of the location of the by-pass corridor in-amd-around the SEA 15, the corridor should be
for regional traffic and should not encourage local access for adjacent development except as required
by safety and emergency access requirements. Construction activity should be limited to the right-of-
way envelope. End points of the corridor would incorporate value criteria.
An environmentally sensitive transportation corridor does not presume to specify. the type of vehicles that will
utilize the facility. Rather, it should encourage and foster high occupancy, clean operation, modes that are
integrated with the corridor. Planning efforts should look to the future and anticipate technologies that will
emerge and contribute to development of a corridor that meets the growing travel demands of the region and
maintains precious natural resources.

2. Transit and Paratransit Services
Both fixed route transit and Paratransit service operate within the City of Diamond Bar. Fixed route transit
services are typically bus lines which operate on regular schedules along a set route, stopping at predefined
bus stops. Fixed route service can be either local (intracity) or regional (intercity). Paratransit services, more
commonly referred to as Dial -a -Ride, are demand responsive services which provide rides to passengers upon
an individual request basis. Although they operate within a defined service area, they do not operate on fixed
routes or schedules. Paratransit service typically serve transit dependent persons such as the elderly and
handicapped. They often serve major destinations such as hospitals and medical facilities but may also take
passengers to local destinations such as neighborhood shopping centers.
a. Transit Services:
Public, bus transit service is provided to the City of Diamond Bar by the Metropolitan
Transportation Authority and Foothill Transit and Orange County Transportation Authority.
:� Four fisted route transit lines serve the City of Diamond Bar. WA Foothill Transit
Route 482 and MTA Route 490 --Of "" keesit
originate and terminate outside
of the city limits. Tian express routes originating at the Park and Ride lot at Diamond
Bar Bl d.,/60 Feeway interchange operate during peak hours Monday dwu Friday. Foothill Transit
Express Route 495 picks up passengers on Golden Springs/Colima to the Puente Hills Mall, then
travels the freeways to downtown Los Angeles. OCTA operates an express route from the same Park
and Ride via Cal State Fullerton, City Drive and the Orange Court House in Santa Ana.9
Additionally three Foothill Transit lines provide intermodal connections at the Industry Metrolonk
Station just north of the city's boundary on Brea Canyon Road. They are Route 482 (Colima Road),
Route 276 (Gale Avenue) and Route 179 (Amar Road).
Paratransit Services:
Diamond Bar General Plan Circulation Element
V-22February 2, 1995 - Staff Revisions } February 10, 1995 - Staff Revisions
Demand responsive transit service is provided to the City of Diamond Bar by the jointly
sponsored Los Angeles County and City of Diamond Bar Paratransit Service. This Dial -a -
Ride service provides transportation to handicapped persons and senior citizens within not
only the City of Diamond Bar but portions of the surrounding area. Transportation is limited
to Los Angeles County, and generally operates south of Valley Boulevard and east of 7th
Avenue, with service to medical facilities within the cities of Pomona, Walnut, Industry and
West Covina.
3. Railroad Lines
There are currently no passenger rail facilities in operation within the City of Diamond Bar. The nearest
Amtrak facilities are located in Pomona and Fullerton. The Pomona Amtrak owien stop, which serves the
Suruet Limited Route. is located at 156 W. Commercial St.
and is approximately nine miles northeast of Diamond Bar. The Fullerton Amtrak station, which serves the
Southwest Chief and San Diegans lines with intermodal _(bus) connections to other Amtrak lines, is located
at the comer of Santa Fe and Harbor Boulevard and is approximately 13 miles to the southwest.
A Diamond Bar is served by a Metrolink commuter rail station bap4sm recently implemented along the Union
Pacific Railroad at Brea Canyon Road, just north of State Route 60.
The Union Pacific Railroad is the only freight rail line which serves the City of Diamond Bar. The line lies
along the City's northwestern boundary with the City of Industry, and serves the industrial area north of
Walnut Drive and Lycoming Street.
4. Bicycle, Him and Equestrian Trails
Maris BUM
There are three different classes of bikeways which are commonly recognized. A definition
of each bikeway class is presented below:
Class I Bikeway (Bike Path) - A completely separated right-of-way for the exclusive use of
bicycles (and sometimes pedestrians). Cross-flow is minimized by limiting access to
designated points.
Class H Bikeway Bike Lane) - Routes designated by separately striped lanes and signs
along streets or highways. They provide restricted one-way travel for bicycles, although
motor vehicles are sometimes permitted to use the bike lane to make turns and to park.
Class III Bikeway Bike Route) - Roadways in which the travel lanes are shared by motor
vehicles and bicycles whose route is designated by signs only. This type of bikeway does
not provide cyclists with increased privileges, but rather, informs motorists of the cycling
route.

to permit right turns by motor vehicles. Parking is not permitted within the bike lanes except on Golden
Springs near Brea Canyon Road, and on the northbound lane of Diamond Bar Boulevard between Montefino
Avenue and Grand Avenue. Golden Springs Drive north of Diamond Bar Boulevard is designated a Class III
bike route on both sides of the roadway. An additional bikeway is yremged to maw jh&uA got

There are currently no Class I bikeways within the City of Diamond Bar.
The County plans to have bicycle routes serving the region that will connect with local bicycle trails. The
county system proposes bicycle trails to enter Diamond Bar at the eastern end of Grand Avenue, and north
into the Tres Hermanos property along Tonner Canyon. Surrounding cities have also planned bicycle routes
to connect from Diamond Bar north along Mission Boulevard (City of Pomona), west along Grand Avenue
and Brea Canyon Road (the Cities of Walnut and Industry), and west along Golden Springs Drive (into
Rowland Heights), east along Grand Avenue (City of Chino Hills), and south along Chino Hills Parkway (City
of Chino Hills).

6. Goods Movement
Goods movement within the City of Diamond Bar occurs primarily through the use of trucks. The City has
established a designated tfuck route plan. Truck routes direct heavy truck traffic onto arterial and collector
facilities and away from local (residential) streets. This plan helps control noise and air pollution in residential
areas of the City and protects local streets from significant surface damage that might result from heavy truck
traffic.
North of the combined section of the Orange L57,1/Pomona (60) Freeway it is necessary for freeway traffic to
exit onto Diamond Bar Boulevard when traveling southbound on the Orange Freeway en route to the
eastbound Pomona Freeway; and westbound Pomona Freeway traffic bound for the northbound Orange
Freeway. The section of Diamond Bar Boulevard between the eastbound Pomona Freeway ramps and the
northbound Orange Freeway ramps to the north, and Sunset Crossing Road between Diamond Bar Boulevard
and the southbound Orange Freeway ramps are designated truck routes.
To enable access to the heavy industrial areas of the City of Industry and the City of Diamond Bar north of
Lycoming Street, truck routes are designated in western Diamond Bar along Golden Springs Drive between
Lemon Avenue and Brea Canyon Road, along both Brea Canyon Road and Lemon Avenue north of Golden
Springs Drive, and along Walnut Drive.
Entrances into the City notify drivers of a five -ton weight restriction for trucks within the City (except for
designated truck routes), in addition to parking restrictions which limit commercial vehicles over five tons to
30 minutes.
The General Plan Designated Truck Routes are illustrated in Figure V-5.
C. CIRCULATION ISSUES
The following significant issues concerning circulation are not necessarily listed in order of priority.

ISSUE ANALYSIS: The City needs policies to address impacts to all streets in Diamond Bar and
to maintain or imy roadway level -of -service standards.
2. Projected Growth in the Region
In addition to increases in traffic attributable to growth and development within the City of Diamond Bar
itself, the City will be impacted by future growth and development in surrounding communities and the region.
Increased traffic in the region will impact Diamond Bar through increased traffic volumes along the regional
transportation facilities including Routes 57 and 60 and Grand Avenue.
ISSUE ANALYSIS: The City needs policies to address impacts to all streets in Diamond Bar and
to maintain or improve roadway level -of -service standards.

3. Future Roadway System Within Diamond Bar
Many of the roadway facilities within Diamond Bar are projected to carry volumes of traffic at or in excess
of recommended daily capacity by the year 2010. At present, a significant amount of the traffic is regional
traffic with neither origin nor destination within the City. Examples are as follows:
Diamond Bar Boulevard - Average daily traffic volumes along Diamond Bar Boulevard immediately south of
Grand Avenue are projected to be double the desirable volumes for a four -lane roadway. South of Grand
Avenue to Brea Canyon Road, forecast daily volume along Diamond Bar Boulevard exceed recommended
carrying capacity. North of Sunset Crossing, traffic volumes along Diamond Bar Boulevard are projected to
be within the carrying capacity of a four -lane roadway.
Golden Springs Drive - Year 2010 traffic volumes along Golden Springs Drive west of Brea Canyon Road
are projected to exceed the desirable maximum volumes for this four -lane roadway. From east of Lemon
Avenue to the City of Diamond Bar boundary, Golden Springs Drive is forecast to carry traffic at or slightly
below the recommended carrying capacity for a four -lane roadway.
The portion of Golden Springs Drive east of Grand Avenue is not a divided roadway and forecast traffic
volumes along this segment would exceed capacity.
Grand Avenue - Year 2010 traffic volume forecasts along the entire length of Grand Avenue within the City
of Diamond Bar are estimated to be in excess of the desirable maximum volumes for a four -lane divided
roadway.
Brea Canyon Road - The section of Brea Canyon Road from Golden Springs Drive to Washington Street is
projected to carry traffic volumes requiring arterial capacity.
Routes 57 and 60 - Both the Pomona Freeway (SR -60) and the Orange Freeway (SR -57) are forecast to carry
traffic volumes significantly in excess of their capacity. This will result in continued congestion along these
facilities with spillover onto City streets as motorists seek less congested alternatives.
ISSUE ANALYSIS: The City needs to establish roadway elassfications and standards for
dedication and roadway improvement for the principal streets in the City.
4. The Development of an Alternative Travel Corridor Around the City of
Diamond Bar
With significant development planned for the Chino Hills area, both Diamond Bar Boulevard and Grand
Avenue are expected to carry larger through traffic volumes from SR -57 than at present into San Bernardino
County. Alternative routes to the south would help relieve future congestion along these and other arterials
within the City of Diamond Bar. However, .the location of an alternative travel corridor must consider its
potential environmental and growth -inducing impacts. Under these circumstances, it will be prudent for the
City to consider the option of a by-pass corridor. Studies of such a facility indicate that should forecasted
development and freeway improvements occur, a by-pass corridor will provide substantial relief to the key
streets in Diamond Bar. Therefore, it will be the policy of the City to:
• not wait until need for the by-pass corridor is demonstrated, but proactively monitor signs
for the need so that timely planning and environmental steps can be taken;
Diamond Bar General Plan Circulation Element
February 2, 1995 - Staff ReWslons } - February 10, 1995 - Staff ]Wsiow V-30
a
explore regional options for transportation improvements prior to initiating development of
a regional by-pass corridor;
seek cooperation of adjoining jurisdictions in managing growth and assigning responsibility
for infrastructure improvements to support that growth; and
establish criteria under which a by-pass corridor would be considered, designed, constructed,
and utilized.
ISSUE ANALYSIS:
There is a need to consider a by-pass roadway around the City of Diamond
Bar to discourage
regional traffic from using the eines City's local streets for cut -through
purposes only. This is of regional concern and involves multiple
jurisdictions. It is important for the City to take the lead in assuring that
any proposed project directly benefits Diamond Bar residents and achieves
the goals of this General Plan.
5. Maintaining Grand Avenue's Current Traffic Carrying Capacity
Grand Avenue is a major arterial and '
A�wme provides an convenient alternative as a regional arterial, carrying traffic
tolfrom Routes 57/60.
ISSUE ANALYSIS: The City will continue to monitor the effectiveness of Grand Avenue in
serving its local needs while
maintaining its current traffic -carrying capacity within the acisting right-of-
way, eswid ixWudet Ongoing efforts include:
• Optimizeing signal eeerdieetiea synchronization;
• ReeeestrneEies Encouraging projects to improve interchange at Route 57/60; and

It is desirable to reduce the use of Diamond Bar $eelev"d Wft by ihm++8h regional traffic.
ISSUE ANALYSIS: One of the most feasible approaches the City can take to reduce threngh
regional traffic on Diamond Bar Boulevard is to work with Caltrans to

improve conditions on State Route 57 and 60. Possible improvements
include:
Upgrade the SR 57/60 interchange to eliminate undue at -grade conflicts and weaving
maneuvers and adding lanes or frontage roads between key interchanges;
Provide HOV and connectors lanes on both SR -57 and SR -60; and
Provide truck climbing lanes where appropriate.

Sunset Crossing is presently a four -lane roadway providing access to/from a residential area of northwest
Diamond Bar. Sunset Crossing west of Route 57 has an interchange with southbound Route 57, extends
westerly and terminates east of the City limits adjacent to a park and Little League field. Tae County of Los
Angeles Highway Plan assumes Sunset Crossing is to be extended southwesterly, through the City of Industry
to a connection with Washington Street or in the vicinity.

Tie City of Industry is
considering the developmtnt of the area beyond the terminous of Sunset Crossing Road, Beaverhead Drive,
Washington Strew and Lycoming Street with industrial uses and a waste -to -rail materials recovery facility to
make maximum advantage of its proximity to freight rail lines. The area through wfiich these streets would be
extended is presently undeveloped. The extension of these streets and the proposed development of industrial
.0 uses would significantly increase the volume oftraffic along these residential streets and introduce a significant
number of trucks into these residential neighborhoods.
ISSUE ANALYSIS: The City should implement stronlg !measures to maintain the integrity of
residential neighborhoods.
D. GOALS, OBJECTIVES AND STRATEGIES

PUBLIC HEALTH AND SAFETY ELEMENT
Page IV -4
Section 8
modify second paragraph to read as follows:
In addition to noise produced by the freeways there are several
local roadways generating 65 CNEL levels beyond the right-of-way.
These include sections of Brea Canyon Road north of the 60
Freeway, Golden Springs Drive East of Lemon Avenue and west of
Prospectors Road, Diamond Bar Boulevard north of Golden Springs
Drive, Grand Avenue west of Golden Springs Drive, Pathfinder Road
east of the 57 Freeway and Sunset Crossing west of the 57
Freeway.
Finally, the Union Pacific railroad line along the westerly
boundary of the City is a major contributor of local noise as are
infrequent urban sources such as dogs barking and aircraft
overflights. Figure IV -1 depicts existing sensitive noise
receptors located adjacent to major noise sources.
