Overview and Purpose
The Garvey Avenue Corridor Specific Plan provides a long-term strategy for
revitalizing and increasing the development potential of the Garvey Avenue
Corridor, particularly with regards to its underutilized commercial and light
industrial spaces. The corridor has the potential to become an iconic and attractive
area for residential, shopping and entertainment, with improved access to
destinations and an inviting environment for bicycle and pedestrian activity. The
Specific Plan will establish land use, transportation, infrastructure, economic
development, and urban design strategies that seek to attract investment into the
corridor, and promote well-balanced retail development, mixed-use development,
and active public spaces. This will all contribute towards a more unified aesthetic
and greater sense of place within the Specific Plan area.
Garvey Avenue Corridor Specific Plan Process
This Garvey Avenue Corridor Specific Plan Technical Memoranda Compendium is
one of the first steps in the Specific Plan’s planning process. This Compendium
compiles and analyzes technical land use, urban design, transportation, and
infrastructure (sewer, water, storm drainage) information and provides a
“snapshot” of the Garvey Avenue corridor today. Coupled with information
gathered from:
Garvey Avenue Specific Plan Ad Hoc Committee in its meetings,
eight neighborhood stakeholders who participated in the Stakeholder
Interviews conducted on July 31, 2014 by City staff,
City staff department representatives, and
76 members of the public who responded to surveys conducted on August 5,
2014 at Rosemead’s National Night Out Event
A series of land use alternatives will be prepared for the Garvey Avenue corridor.
The alternatives will be vetted and, ultimately, a preferred plan will be selected.
Based on this preferred plan, a Draft Garvey Avenue Specific Plan will be prepared
and the Draft Plan will be analyzed in an environmental impact report.
Generally, the Garvey Avenue Corridor Specific Plan schedule is anticipated to be:
Alternatives Generation – Early Fall 2014
Preferred Alternative – Fall 2014
Administrative Draft Specific Plan – Winter 2014
Environmental Review – Spring 2015

Planning Area
The Garvey Avenue Corridor Specific Plan area lies within the City of Rosemead,
which is part of Los Angeles County. The City of Rosemead is bordered by the cities
of Temple City and San Gabriel to the north, the cities of San Gabirel and Monterey
Park to the west, unincorporated areas of Los Angeles (South San Gabriel) and the
cities of Montebello and South El Monte to the south, and the City of El Monte to the
east. Excluding the street and its right-of-way, the project area covers 0.1375
square miles, encompassing the commercial and light industrial parcels surrounding
an approximate 1.2 mile-length section of Garvey Avenue, as show in Figure 1.1.
Residential uses are also located surrounding the project area. Some of the
planning area contains vacant or underutilized commercial and light industrial
spaces. The easternmost boundary is Charlotte Avenue, while New Avenue marks
the westernmost boundary of the project area. The northern and southern
boundaries of the project area vary by segment of Garvey Avenue, but Newmark
Avenue stands as the southernmost boundary, and Whitmore Street is the
northernmost boundary.
Regional access to the planning area is provided by Interstate 10, California State
Route 19 (Rosemead Boulevard), and California State Route 60. Interstate 10 (I-
10) is situated about half a mile north of Garvey Avenue and Route 60 (SR-60) is
located approximately 2.5 miles south. State Route 19, better known as Rosemead
Boulevard, runs north-south between the two freeways, just east of the project
area boundary.
Technical Memoranda Compendium
This document, “Garvey Avenue Corridor Specific Plan Technical Memoranda
Compendium,” is a compilation of technical analysis prepared by land use planners,
economists, civil engineers, and traffic engineers. The Technical Memoranda
Compendium profiles the existing characteristics, trends and forecasts, and issues
that affect the corridor in 2014. The Compendium provides specific information on
land use, urban design, transportation and circulation, infrastructure (water, sewer,
and storm drainage), and the local developer perspective. The information
contained in this document is intended to assist the planning team and the
policymakers with making informed planning decisions regarding the Garvey
Avenue Corridor Specific Plan. The Technical Compendium is one of the first steps
in the process of preparing the Garvey Avenue Corridor Specific Plan.

This technical memorandum documents baseline conditions for land use along
Garvey Avenue within the project area in Rosemead. It identifies key issues
relevant to the corridor today and provides a context for examining development
constraints and opportunities for land use changes. The information presented in
this technical memorandum will be used to develop a Specific Plan that reflects
current trends and development patterns.
The following sections of the Land Use Technical Memorandum:
Describe recent and current land use planning efforts along Garvey Avenue;
Detail Rosemead’s development history;
Identify current land use and zoning conditions;
Describe major development projects and trends;
Analyze existing densities and intensities; and
Identify potential opportunity sites.
Recent and Current Land Use Planning Efforts
Existing plans provide a starting point for an existing conditions analysis of land use
within the Garvey Avenue Corridor. Several recent and current land use planning
efforts have helped shape development patterns within Rosemead. These include
the existing General Plan, the Zoning Code, specific plans, and other regional plans
and initiatives.
Existing 2010 General Plan Update
Any land use approach for Garvey Avenue must be consistent with the primary
goals of Rosemead’s General Plan, which was last updated in 2010 (the Housing
Element was separately adopted in 2013). The 2010 General Plan Update provides
a citywide approach to planning for future development, and outlines goals and
strategies for major commercial corridors such as Garvey Avenue. It considers the
seven required General Plan elements, including land use, circulation, housing,
open space, conservation, noise, and safety, in six chapters, with conservation and
open space combined into a Resources Management element. The plan identifies a
set of goals, policies, and actions related to each of the chapters.
Five of the six primary vision elements of the 2010 General Plan Update apply to
Garvey Avenue, including:
Enhance the commercial areas along key corridors, and most specifically
Garvey Avenue and Valley Boulevard;
Enhance parks and recreational space in underserved neighborhoods;
Land Use
Page 2-2 Rosemead Garvey Avenue
Technical Memoranda Compendium
Accommodate the demand for quality mixed-use development that can
contribute to commercial growth and enhance opportunities for higher-
density residential development;
Protect homeowner investments and the availability of well-maintained,
relatively affordable housing units; and
Minimize the impact of traffic associated with growth within the San Gabriel
Valley and broader region
The goals laid out in the 2010 General Plan Update that relate to potential land use
decisions along the Garvey Avenue Corridor include the following:
Land Use Element
Goal 2: Expand opportunities for concentrated commercial and industrial
uses that contribute jobs and tax revenues to the city
Goal 3: Create vibrant, attractive mixed-use development
Goal 4: Assure a financially healthy City that can meet residents’ desire for
public services and facilities
Goal 5: Use targeted land use changes that improve housing and economic
opportunities for residents and businesses and achieve City fiscal and
environmental objectives.
Circulation Element
Goal 1: Maintain efficient vehicular and pedestrian movements throughout
the City
Goal 2: Develop infrastructure and service to support alternatives modes of
travel
Goal 3: Assure vehicular traffic associated with commercial and industrial
uses does not intrude upon adjacent residential neighborhoods
Goal 4: Provide quality commercial and industrial development with adequate
parking for employees and visitors
Resource Management Element
Goal 1: Provide high-quality parks, recreation, and open space facilities to
meet the needs of all Rosemead residents
Goal 2: Increase green space throughout Rosemead to improve community
aesthetics, encourage pedestrian activity, and provide passive cooling
benefits
Goal 4: Make effective contributions to regional efforts to improve air quality
and conserve energy
Noise Element
Goal 1: Ensure effective incorporation of noise considerations into land use
planning decisions
Goal 2: Reduce noise impacts from transportation sources
Land Use
Rosemead Garvey Avenue Page 2-3
Technical Memoranda Compendium
Goal 3: Effectively implement measures to control non-transportation noise
impacts
Housing Element
Goal 2: Encourage the development of a range of housing types in a range of
prices affordable to all Rosemead residents
Goal 3: Encourage the maintenance and upgrading of existing housing stock
to ensure a decent, safe, and sanitary home for all Rosemead residents
Existing Zoning Code
The City’s existing zoning code describes development standards and allowable
uses by zoning district. Development standards identified include setbacks, lot area,
lot width, density, floor area ratio, site coverage, landscaping and open area
requirements, height limits, storage, and parking.
Garvey Avenue Master Plan
The Garvey Avenue Master Plan is a guiding document for development along
Garvey Avenue, and should be a key reference point for the Garvey Avenue
Corridor Specific Plan. It is intended to address “aesthetic and parking issues that
property and business owners face in planning commercial and retail
improvements.” Its vision for Garvey Avenue: “In the year 2020, Garvey Avenue
will be recognized as a vibrant corridor with clean storefronts and visible pedestrian
activity. Garvey Avenue will create a sense of ‘Small Town’ community pride where
a variety of opportunities can be discovered for families and friends.”
Its key objectives include the following:
Upgrade the image and appeal of the Garvey Avenue corridor by coordinated
public and private improvements.
Entice and create convenience for patrons to stop and shop along the Garvey
Avenue commercial corridor.
Create energy along Garvey Avenue by creating pedestrian activity and
sidewalk cafes with outdoor seating.
Develop great place-making areas that will define the Garvey Avenue
commercial corridor.
Create adequate parking facilities and improve traffic flow along the
commercial corridor.
Promote and encourage the highest and best use of under-utilized properties.
Utilize landscaping as an integral component to overall project design.
Consider scale and character of adjacent uses and demonstrate sensitivity to
the influences of the surrounding area.
Encourage private rehabilitation through application of the Garvey Avenue
Master Plan for new and existing businesses.
Strengthen the Property Maintenance Ordinance to rigorously enforce
property maintenance standards for commercial and industrial properties.
Land Use
Page 2-4 Rosemead Garvey Avenue
Technical Memoranda Compendium
Its action plan includes:
Revise the Property Maintenance and Sign Ordinances to clearly address
commercial property maintenance (e.g. clean storefronts, parking lot
improvements, sign rehabilitation, etc.).
Recognize that different parts of the corridor have special characteristics, and
develop programs to strengthen and reinforce them.
Direct project designs that will promote pedestrian-friendly projects with
public spaces and lively street fronts where people can meet and interact.
Encourage developments as a means of upgrading established uses and
developing vacant parcels along Garvey Avenue.
Attract private investment to revitalize older commercial uses that will
reinforce and create synergy along the Garvey Avenue commercial corridor.
Enforce high quality commercial building and site design while allowing
increased intensities of use along the corridor where appropriate.
Require economic feasibility studies on large development sites to ensure
projects are economically sustainable.
Establish a well-balanced and carefully planned collection of signature retail
anchors, general retail outlets, casual to upscale restaurants, and upscale
overnight accommodations.
Discourage the development of commercial properties that contain a random
mix of incompatible uses.
Encourage the placement of parking areas to be located behind structures
and out of sight from the public right of way.
Promote lively and attractive ground-floor retail uses that will create
revenues needed to provide for City services and City’s tax base.
City of Rosemead Mixed Use Guidelines
Rosemead’s Mixed Use Guidelines, adopted in 2010, provide a context and strategy
for mixed use development throughout the city. To the extent that development
within the Garvey Avenue Corridor Specific Plan area is proposed to be mixed use,
the Mixed Use Guidelines will offer important guiding principles to follow. The
Mixed Use Guidelines include sections devoted to:
The public realm and the pedestrian environment
Site design
Building design
Building height
Storefronts
Lighting
Common areas/open space
Compatibility with adjacent properties
Parking
Access
Land Use
Rosemead Garvey Avenue Page 2-5
Technical Memoranda Compendium
Downtown Rosemead Design Guidelines
Rosemead’s Downtown Design Guidelines are intended to guide development in the
Central Business District (CBD) of the city, along Valley Boulevard east of Walnut
Grove Avenue. As such, while they do not directly apply to the Garvey Avenue
Corridor Specific Plan, the goals and principles contained within them may be useful
in considering goals and principles for the Garvey Avenue Corridor Specific Plan. Its
three strategic goals – beautify community infrastructure and improve public
facilities, enhance public safety and quality of life, and ensure the City’s financial
viability with balanced budgets and prudent reserves – all dovetail well with the
strategic goals of the Garvey Avenue Master Plan. Its design objectives are likewise
relevant and useful, and include:
Upgrade the image of the City’s Downtown area by coordinated public and
private improvements
Consider privacy, noise, light (glare), and traffic intrusion.
Consider scale and character of adjacent uses and demonstrate sensitivity to
the influences of surrounding area.
Stimulate future private investment.
Make the best use of under-utilized properties.
Facilitate and encourage pedestrian activity.
Utilize landscaping as an integral component to overall project design.
Design building forms and elevations that contribute to the overall quality of
the built environment.
Consider scale and character of adjacent uses and demonstrate sensitivity to
the influences of the surrounding area.
Encourage private rehabilitation through application of the Designs
Guidelines for new and existing businesses.
Create a form of uniformity in the City.
Regional Comprehensive Plan and Guide
Within the greater Los Angeles Metropolitan Area, regional planning efforts are
underway to provide a regional context for planning, and ensure consistency and
encourage collaboration across city borders. These planning efforts are led by the
Southern California Association of Governments (SCAG), which “undertakes
regional planning efforts for the six-county SCAG region consisting of Los Angeles,
Orange, Riverside, San Bernardino, Ventura, and Imperial counties. SCAG's
planning efforts focus on developing strategies to minimize traffic congestion,
protect environmental quality, and provide adequate housing throughout the
region. The Regional Comprehensive Plan and Guide – developed with active
participation from local agencies, elected officials, the business community,
community groups, private institutions, and private citizens – sets forth broad goals
and objectives intended to be implemented by participating jurisdictions and
Land Use

Technical Memoranda Compendium
agencies such the South Coast Air Quality Management District and Los Angeles
County Metropolitan Transportation Authority.”1
History of Land Use Development
Incorporated in 1959, Rosemead had been settled long before, first by Gabrieleno
Native Americans and then by the Spanish, who established a mission in the San
Gabriel Valley in 1771.2 For centuries, Rosemead was predominantly an
agricultural community, with a compact business and residential core surrounded
by farms, orchards, barns, and other agriculture-based uses. Soon after the City
was incorporated, major changes began to transform Rosemead.
In 1959, the population of Rosemead was 15,475. From 1960 to 1970, the
population exploded, to nearly 41,000. This growth was primarily suburban tract
house development to accommodate families and workers in the Los Angeles
metropolitan area. The growth dramatically changed Rosemead from an agricultural
community to a suburban city, primarily a residential suburb with some limited
commerce and industry. Growth slowed in the 1970s, and then picked up again in
the 1980s, growing from 42,604 in 1980 to 51,638 in 1990. Growth has been slow
since 1990, with the population in 2010 census at 53,764. Official predictions
anticipate that Rosemead will grow to just under 60,000 by 2020.
Rosemead is among the 88 cities that comprise Los Angeles County. Since
incorporation, and particularly since the 1990s, Rosemead has fast become an
increasingly diverse community. Large numbers of Chinese and Vietnamese
immigrants began settling and setting up businesses in Rosemead in the 1990s,
and by 2010 the city was over 60% Asian, with another 34% identifying as Latino.
This demographic transformation has resulted in a changed Garvey Avenue.
Excluding chain stores, virtually all retail businesses are Asian-oriented. As stated
in Rosemead’s General Plan, it will be important that the Garvey Avenue Corridor
Specific Plan also meets the needs of the diverse population living and working
along the corridor.
Analysis
Existing Land Use and Zoning Conditions
This section details land use and zoning within the project area along Garvey
Avenue in 2014. It highlights the land use pattern and zoning, outlines the baseline
land use, and classifies commercial uses by specific use. Much of the analysis in
this section took place after a land use and urban design survey conducted at the
site on July 1, 2014.

Technical Memoranda Compendium
2014 Land Use Pattern
Land use in Rosemead is tied to the city’s geography and historical pattern of
development. Rosemead is relatively flat land with few topographical impediments
to development. The I-10 freeway bisects Rosemead creating a major barrier and
edge to local neighborhoods. According to the City of Rosemead’s website, the City
of Rosemead encompasses 5.5 square miles of land area, including roads and other
rights-of-way. Out of this total number, 64% of land area is in residential use, 14%
for public facilities including 1.4% for parks, 9% for commercial uses, 7% for
mixed-use (commercial and residential), and 6% for office and light industrial uses.
There are 74.4 miles of streets and alleys within the City of Rosemead.3
The Garvey Avenue project area is, likewise, flat and has no major barriers to
development. The project area along Garvey Avenue encompasses 88 acres, and is
composed of some 153 parcels of varying land use. A majority of land uses are
commercial/retail, with 84 parcels in commercial or retail use, encompassing 37
acres (42.3% of the total project area). This acreage includes off-street parking
lots serving the commercial buildings, which represent underutilized land. (See the
Urban Design existing conditions section for parking analysis.) There are also a
large number of vacant parcels: 43. Vacant land makes up 30.4 percent, or nearly
27 acres, of the land area. Other allocations of land uses along Garvey Avenue
include 1.7% for single-family residential, 8.5% for multi-family residential, 1.4%
for multi-use, 14.8% for institutional, and 0.9% for open space. Specific acreages
and a further breakdown of these categories are detailed in Table 2.1 below.

Technical Memoranda Compendium
Single Family/Duplex and Multi-Family Residential
Rosemead’s population, approximately 54,000, lives in the city’s estimated 14,578
housing units.4 The balance of renter/owner in these housing units is roughly
50/50, with slightly more (51.5%) renters than owners. About 82 percent of
Rosemead’s housing units are single-family homes, with 15% of the remainder
being multi-family housing units and the remaining 3% being mobile homes.
The Garvey Avenue project area is bordered and surrounded by single-family or
low-density multifamily housing in all directions. Most of these residential areas are
zoned for “light multiple residential” use, which allows for a density of up to 12
units per acre. Within the project area itself, there are a handful of small pockets
zoned for residential use, including the existing trailer park at the Garvey Avenue
and New Avenue intersection; near the former Los Angeles Auto Auction (“Auto
Auction”) site just south of Virginia Street and north of Garvey Avenue; the small
northernmost parcel of the Paradise Trailer Park; the lower four parcels of the
vacant land on the southern side of Garvey between Kelburn and Falling Leaf
Avenues; and the Garvey Intermediate School site.
The majority of the housing units within the project area are mobile homes.
Specifically, these housing units are within the mobile home park just east of New
Avenue, which lies partly in Rosemead and partly in Monterey Park; and the
Paradise Trailer Park and Apartments, squeezed between two large parcels of
vacant land, the Auto Auction site to the west and a large triangular parcel
bordering Alhambra Wash to the east. Based on land area, multi-family uses make
up 8.5 % of the total land area and single family and duplex uses make up 2%.
Residential development proposals in the Garvey Avenue area include medium- to
high-density mixed-use development. The proposed project includes a 4-story
Garvey Del Mar Avenue Plaza mixed-use building in the vacant site on the northeast
corner of Garvey and Del Mar Avenue.
Commercial
Commercial uses in Rosemead make up 9% of the developable land area and range
from neighborhood retail along Del Mar Avenue and San Gabriel Avenues to locally-
serving retail businesses in the central business district on Valley Boulevard to
regional-serving big box retail on Rosemead Boulevard north of the I-10. Local-
serving commercial uses are located within neighborhoods throughout Rosemead
and include restaurants, cafes, supermarkets, and other types of retail.
Within the Garvey Avenue project area, both land use and zoning are primarily
commercial, although a significant number of parcels zoned for commercial use are
currently vacant. There is also one existing area of mixed-use residential and
commercial development, on the north side of Garvey Avenue at Isabel Avenue.

173 commercial/retail businesses are located within the project area. Of these,
135, or 78%, are retail businesses, while the remainder is non-retail commercial
uses. Of the 135 retail uses, 122 or 88%, are local retail, while 16 (11%) are chain
stores or formula-retail, defined as businesses with over 10 stores nationally.
Restaurants are the single largest commercial use, accounting for 22% of the total
commercial uses. Professional services (13%), auto-related uses (10%), beauty
salons and supply (10%), and medical/dental businesses (10%) are other major
commercial uses. Specific percentages and a further breakdown of these categories
are detailed in Table 2.2 below.

Office and Industrial/Manufacturing
Given Rosemead’s history as a bedroom community, the area has not attracted
significant amounts of high-technology, office, or industrial/manufacturing uses.
Within the Garvey Avenue project area, no industrial or manufacturing uses occur.
There are pockets of office uses, but primarily the corridor is a retail commercial
area.
The closest industrial area to the Garvey Avenue project area is along San Gabriel
south of Garvey Avenue. Several other of the few manufacturing areas are located
along or just below Garvey Avenue one half-mile east of the project area corridor,
east of Walnut Grove. Office space is predominantly sited in the southern edge of
the city, such as the large Edison International office facility on Walnut Grove
nearly one mile south of Garvey Avenue.

Parks and Open Space
The City of Rosemead suffers from a lack of parks and open space, and does not
have a wide range of parks and open space. Rosemead has 43 acres of open space
within the city, representing just 1% of the more than 3,500 total acres of land
area.
There are few trails and virtually no high-quality bikeways either within existing
parks or connecting existing open space. The Rio Hondo corridor, a small portion of
which passes through Rosemead, does have a paved trail along its concrete banks,
and becomes a natural green oasis in the Whittier Narrows Recreational Area,
directly southeast of Rosemead in the City of South El Monte. Public access was
not preserved to either Alhambra Wash or Rubio Wash in Rosemead; as a result
neither has a trail or open space of any kind along its length. Portions of the
Southern California Edison easement, however, have been creatively used as open
space.
The Garvey Avenue project area is representative of the lack of open space within
Rosemead. There are no parks or open spaces within the project area. The front
“yard” of Richard Garvey Intermediate School provides grassy green space directly
on Garvey Avenue, and there is a large grassy area in the rear of the school
complex, although it is fenced off to the public. Within the project area, an
opportunity exists to create public open space along Alhambra Wash north of
Garvey Avenue as it reaches San Gabriel Avenue.
Institutional/Public Use
Institutional and public uses include schools, public facilities, churches, and medical
facilities, among others. These uses make up 14% of land in Rosemead, and a
similar 15% of land within the project area, the vast majority of which is contained
within the bounds of Richard Garvey Intermediate School. Other institutional uses
include the Buddhist Ortho-Creed Association Dharma Seal Temple at 3027 Del Mar
Avenue, the Viet Nam XALOI Buddism Study Association Inc. at 2755 Del Mar
Avenue, and the South San Gabriel congregation of Jehovahs Witnesses church at
2754 Del Mar Avenue.
Parking
Large amounts of commercially-designated land are dedicated to off-street parking.
Figure 2.3 shows off- and on-street parking. An analysis of land allocated to
parking can be found in the Urban Design technical memorandum.

Vacant
Parcel data and land use site surveying and analysis identified parcels within the
Garvey Avenue corridor project area that are vacant. This analysis showed that
there is a large amount of vacant land within the corridor. Some 43 of the total
153 parcels, or 28%, are currently vacant, covering 27 acres, or 30% of the total
land area. Vacant land refers both to open, unbuilt land, most of which is already
paved, but also refers to unoccupied buildings.
The single largest vacant parcel is the former Los Angeles Auto Auction (“Auto
Auction”) site, on the north side of Garvey Avenue centered on Kelburn Avenue. It
is nearly 17 acres of vacant land. It is designated a “high-intensity” commercial
area in Rosemead’s Land Use Plan, and is zoned C-4 Regional Commercial. Other
vacant land areas include several parcels east of the Auto site, bisected by
Alhambra Wash, which comprise nearly 4 acres; a 1.4 acre area due south of the
Auto Auction site between Kelburn and Falling Leaf Avenues; and several other
smaller parcels near Del Mar and New Avenues targeted for development. Figure
2.4 shows vacant land – both built and unbuilt – within the project area, and Figure
2.5 shows images of several existing vacant parcels.
Underutilized Land
A number of parcels within the project area are underutilized, and, if developed to
their full potential, could offer a significant increase in development capacity. A
map of parcels deemed to be underutilized, defined as developed to less than 60%
capacity, is shown in Figure 2.6. Several of these parcels are actively in business,
and as such may not be appropriate targets for redevelopment; these include a
number of fast-food restaurants that have parking lots far bigger than their
buildings. Other sites include auto-oriented businesses such as repair shops which
have large open parking lots.

Technical Memoranda Compendium
Zoning Ordinance
The City’s zoning ordinance plays a key role in guiding development type, density
and use. Under California law, Rosemead’s zoning ordinances must be consistent
with a City’s General Plan. Designated zoning districts, therefore, directly
correspond to the General Plan land use designations as shown in Table 2.3.
Only a few types of zoning districts are found within the Garvey Avenue Corridor
Specific Plan area, which are shown in the Zoning Map in Figure 2.7. They include:
R2 – Light Multiple Residential
The R2 zoning district is intended for single family dwellings, duplexes, low-density
rowhouse developments, low-density townhouse developments, small-lot single
family developments and similar and related compatible uses. A maximum density
of twelve dwellings units per acre is allowed. The R2 zoning district is consistent
with the Medium Density Residential land use designation of the General Plan.
C3 – Medium Commercial Neighborhood
The C3 district provides convenient shopping for residential neighborhoods,
including retail and service uses including grocery stores, cleaners, restaurants,
beauty salons, tax preparation and similar and related compatible uses. The C3
Zoning District is consistent with the Commercial land use designation of the
General Plan. The majority of zoned parcels within the study area are zoned C3 –
Medium Commercial. A D - Design Overlay zoning designation provides further
refinement for specific parcels at the Garvey Avenue and San Gabriel intersection,
requiring an additional layer of design review for all proposed development.
C4 – Regional Commercial Service
The C4 district provides regional commercial and service uses that serve local and
regional residents and businesses. The C4 zoning district is consistent with the High
Intensity Commercial land use designation of the General Plan.
P – Automobile Parking
The P district specifically provides for automobile parking. It includes the parcels of
Alhambra Wash.
P-D – Planned Development
The P-D district is designed to provide for uses that may be developed as a planned
area development. Additional consideration to planned circulation patterns,
residential densities, coverage limitations, and preservation of open spaces should
be included in developments within these districts.

Major Development Projects and Trends
While Rosemead is almost completely built-out, with little vacant or underutilized
land currently available for new development, a large amount of the vacant,
unoccupied buildings, or underutilized land within Rosemead is along Garvey
Avenue in the project area. This section describes recent major developments and
pipeline projects as well as current land use trends related to residential and non-
residential development.
Pipeline Projects
The following developments are pipeline projects in the project vicinity including
those that are under construction, approved and not yet constructed, and those still
under review by City staff (see Table 2.5 and Figure 2.8).

Key Findings
The majority of existing land uses along the Garvey Avenue Corridor within
the project area adhere to the zoning code.
There is a considerable amount of vacant land within the project area.
Accordingly, there are small, medium, and large opportunities to develop
these vacant parcels with beneficial catalytic development that improves the
streetscape, the commercial environment, and quality of life for residents.
Supporting a mix of land uses is important to the ongoing success of the
corridor, but this mix of land uses demands that the corridor become a
livable street that is safe, pleasant, and healthy to live directly on.
A large amount of land and right-of-way is dedicated to vehicle parking. With
so many large off-street parking lots, long stretches of on-street parking
stand empty much of the day, although there are pockets where on-street
parking seems better used and is potentially more important for the few
small businesses that do not have off-street parking lots.
There are opportunities to strategically link land use decisions with existing
transportation infrastructure. Locating residential uses within walking
distance to transit stops will help capitalize on the city’s transportation
options.
Potential land use conflicts exist in some areas between residential uses and
higher intensity uses (mostly commercial), which can result in issues related
to noise, emissions, pedestrian safety, and traffic, among others. Careful
design of transition areas between single family residential and commercial
areas should be used to address these land use conflicts.
There is a deficiency of open space along the corridor, which underscores the
need to work with developers to increase the amount of open space as
vacant parcels are developed and as other parcels are revitalized/recycled.
Rosemead can use land use to support and enhance existing neighborhoods
and improve the overall livability of the city. Livability encompasses many
dimensions, but from a land use perspective it generally deals with safe and
convenient access by any mode to everyday amenities, such as
neighborhood-serving retail, grocery stores, parks, and other amenities.
As the economy evolves in the coming years, there may be pressure to
convert uses to those that are more economically viable. In some cases
changing land use can be appropriate and beneficial to community. However,
converting too much land to one use can have negative effects on the overall
mix of land use within the city.
Coordinating local and regional land use planning efforts is important for
economic development, transportation, and land use Rosemead. Visioning
and redevelopment plans led by regional planning agencies and surrounding
jurisdictions, including the LA River Revitalization Master Plan, suggest
opportunities that will benefit the city. The City should work with the various
stakeholders and municipalities to coordinate transportation linkages,
development transitions and economic development strategies.

Introduction
3 x
Purpose
This Technical Memorandum addresses the overall physical patterns and
characteristics of Garvey Avenue. It analyzes a range of elements that shape both
private and public realms along Garvey Avenue, and also describes the
relationships between them. The Technical Memorandum provides an overall
physical framework in which key urban design assets, issues, and opportunities are
identified and can be highlighted for future preservation, improvement, or
transformation in the Specific Plan.
The Urban Design Technical Memorandum includes the following sections:
Key findings
Relevant urban design planning efforts
Area character
Key views, landmarks and gateways and
Urban and streetscape design and physical character of the Garvey Avenue
corridor.
Recent and Current Urban Design Planning Efforts
Rosemead established design guidelines for certain uses and within specific areas of
the community. Design guidelines provide a basis for design standards and quality
throughout the City. Design guidelines ensure that property owners, developers,
and the City adhere to high-quality standards and that new improvements have a
cohesive character. Design guidelines that pertain to the Garvey Avenue corridor
are found within the Garvey Avenue Master Plan, the City of Rosemead’s Mixed Use
Guidelines, and, to a lesser extent, the City of Rosemead’s Downtown Design
Guidelines.
Garvey Avenue Master Plan
Of the above three plans, the Garvey Avenue Master Plan’s urban design guidelines
are the most applicable. They deal with and provide guidance for a variety of
elements that contribute directly to urban design along Garvey Avenue corridor,
including:
Architecture
Storefront Design
Roof Articulation
Materials and Colors
Secondary/Rear Façade and Entrances
Lighting
Commercial Signs
Urban Design

Landscaping
Parking
Trash Enclosures
Outdoor Seating
Public Sidewalk
Undergrounding of Utilities
Graffiti-Deterrent, and
Green Design
Key objectives of the Garvey Avenue Master Plan related to urban design include:
Upgrade the image and appeal of the Garvey Avenue corridor by coordinated
public and private improvements
Entice and create convenience for patrons to stop and shop along the Garvey
Avenue commercial corridor
Create energy along Garvey Avenue by creating pedestrian activity and
sidewalk cafes with outdoor seating
Develop great place-making areas that define the Garvey Avenue commercial
corridor
Create adequate parking facilities and improve traffic flow along the
commercial corridor
Promote and encourage the highest and best use of under-utilized properties
Utilize landscaping as an integral component to overall project design
Consider scale and character of adjacent uses and demonstrate sensitivity to
the influences of the surrounding area.
Encourage private rehabilitation through application of the Garvey Avenue
Master Plan for new and existing businesses, and
Strengthen the Property Maintenance Ordinance to rigorously enforce
property maintenance standards for commercial and industrial properties.
City of Rosemead Mixed-Use Design Guidelines
Rosemead’s Mixed Use Design Guidelines also apply, especially to the extent that
new development on Garvey Avenue is mixed-use, to the Garvey Avenue corridor.
As with the Garvey Avenue Master Plan, the Mixed Use Design Guidelines provide
guidance that address a variety of elements that contribute to urban design,
including:
Public Realm and the Pedestrian Environment
Site Design
Building Design
Building Height
Storefronts
Lighting
Common Areas/Open Space
Compatibility with Adjacent Properties
Parking
Access
Urban Design
Rosemead Garvey Avenue Page 3-3
Technical Memoranda Compendium
The overall goals of the Mixed Use Design Guidelines, which relate directly to
mixed-use urban design development, include:
To provide the resident with a high quality living environment
To protect the pedestrian and enhance the pedestrian environment and scale
To design parking that not only meets parking requirements, but also
promotes safe interaction between vehicles and pedestrians
To ensure that retail/commercial uses on the ground floor serve the
community (e.g., restaurants/retail, etc.). Office uses are not encouraged on
the ground floor
To ensure compatibility between adjacent uses, especially single-family
residential, other mixed-use projects, and
To encourage high quality mixed-use infill development that is comprised of
residential, office, entertainment, and commercial uses.
Downtown Rosemead Design Guidelines
Like the Garvey Avenue Master Plan, the Downtown Rosemead Design Guidelines
address the same 15 elements that contribute to urban design in the downtown
area. They also address the integration of public art into public realm design, and
specifically address nine key factors of streetscape and public realm design
improvements, including:
Gateways (public visual or ceremonial entryways)
Intersection Enhancements
Roadway Medians
Paving
Free-standing Potted Plants
Street Pole Banners
Street Furniture
Street Lighting; and
Street Trees

Area Design Character
Assessing Built Form and Urban Design
Walking, living, and driving on busy Garvey Avenue itself, versus on an adjoining
quiet residential local street like Falling Leaf Avenue, provides a very different
experience, most particularly for those staying the longest or travelling the slowest,
such as residents and pedestrians. Walking along one point of Garvey Avenue,
likewise, can be very different from walking along it just a block away. Driving
anywhere on Garvey Avenue is a different experience than taking transit, walking,

Technical Memoranda Compendium
or bicycling. Shopping may be a pleasurable experience on certain blocks, and
frustrating and unpleasant on others. Understanding what it is exactly that
contributes to these different experiences helps understand the positive and
negative elements that, taken together, ultimately create or result in these
experiences. It also helps guide future decisions, making it possible to work
towards bringing in more of what contributes to the more positive experiences and
less of what contributes to the more negative experiences.
Analyzing and understanding existing built form helps assess and understand the
experience of being on various points along the corridor. At the block, parcel, and
street level, built form describes and reveals how a neighborhood’s various pieces
fit together and what that means for the experience of living, working, or passing
through the neighborhood. Are the individual blocks large or small, or is there a
mix? Are the parcels (also called lots) irregularly-shaped and differently-sized or
are they identical in shape and size, row after row? Are the streets wide or narrow,
or is there a mix of widths? Are there midblock alleys, paths or other pedestrian
routes, or just long unbroken segments of lots? The answers to these questions
reveal how a neighborhood was designed and help explain why it may feel livable to
residents, welcoming to visitors, or easy to get around by one, some, or all
transportation modes.
At the building level, the term “built form” describes what a building looks like and
what its shape is on the ground, how tall it is, how much of its parcel it takes up,
how far it is set back from the sidewalk and street, how many windows/doors it has
visible from the street, and its architectural style. Are buildings close to each other
or far apart? Are they just a single story, or are they many stories? Are the
buildings all more or less the same height, or do the buildings vary wildly in height
from one to the next? Do they face the street or face away from the street? Do
they sit directly on the sidewalk or are they set back, with something (a front lawn,
say, or a parking lot) in between? Do the buildings all look the same, or are they
different? Do they have prominent front doors, or more prominent garage doors?
Is there a mix of old buildings and new, or was everything built around the same
time in the same style? Does the façade (the front edge of a building) feel inviting,
with attractive and bright windows and active retail, or is the façade little more than
an empty storefront, blank concrete wall, or a chain-link fence? The answers to
these questions reveal how the buildings in the neighborhood were designed and
why some of them may feel more welcoming than others, or have more successful
retail in them. Well-designed buildings provide a rich context for a neighborhood of
vibrant places.
Study Area Background
The Garvey Avenue corridor is characterized by a unique set of land uses,
development character, block patterns, parcel patterns, and building types, which
together constitute the corridor’s built form (Figure 3.1). The study area for the
Garvey Avenue Corridor Specific Plan is bounded by the City of Monterey Park
following New Avenue to the west; Charlotte Avenue and San Gabriel Boulevard to
the east, and the edges of residential neighborhoods to the north and south. The
Urban Design
Rosemead Garvey Avenue Page 3-5
Technical Memoranda Compendium
block, street, and parcel patterns along the corridor have been shaped in different
ways in response to a myriad of public and private decisions, environmental
constraints, varied land uses, and evolving design trends occurring over many
years. The streets and blocks have also been shaped by key travel routes, housing
trends and parcel availability, and the patterns of neighboring communities.
Garvey Avenue’s built form – its street network, block pattern, parcel pattern, and
building pattern – displays a range of sizes and a diversity of shapes, but its overall
pattern is characteristic of that seen in auto-oriented “strip” corridors with single-
family suburban development around it. Each of the elements that make up its
built form reveals that this is an area designed for cars, in an era when automobiles
were the preferred and predominant form of transportation. There are wide streets
like Garvey Avenue and San Gabriel Boulevard that go through and connect well to
the surrounding street grid, and narrower short streets like Virginia Street and
Lindy Avenue that do not connect as well to the surrounding street grid, with few
midblock alleys or pedestrian passageways. This allows for efficient throughput of
automobiles but makes bicycle and pedestrian circulation challenging because
smaller local roads do not always connect well to the overall street grid. Likewise,
while block sizes vary, they are generally quite large, too large for easy pedestrian
circulation. Parcel sizes vary considerably, but are often too large along Garvey
Avenue for pedestrian-scale development. Finally, the building pattern is regular in
the residential areas but sparse directly on Garvey Avenue, with major empty
“holes” in development seen up and down the corridor, the result of swaths of
vacant land for surface parking lots. All of these measures directly relate to and
have significant effects on the quality of urban design and the pedestrian
environment.

Block Pattern
The Corridor’s block pattern is typical of suburban developments and strip corridors
(see Figure 3.2). A hierarchy of streets gives shape to the neighborhood. The block
pattern includes wider arterial streets such as New, Del Mar, and San Gabriel
Boulevards extending in the north-south direction that afford full connectivity, along
with local streets that end in cul-de-sacs, meet Garvey Avenue at disjointed angles,
or otherwise do not provide good connectivity. East-west running streets
paralleling Garvey Avenue are local streets with limited connectivity and traverse
short distances. The block structure map shows, for example, how Garvey Avenue
allows for “full connectivity,” in that it runs completely through the project area,
unbroken and able to intersect with any other perpendicular-running street in the
area; in total, it intersects with 19 other streets. By contrast, the map also shows
how Whitmore Street, which runs parallel to Garvey Avenue to the north, does not
provide good connectivity, because it intersects only one street, Del Mar Avenue.
The block pattern stops it from running west of Del Mar (even though Whitmore
Street returns again west of Jackson Avenue), and ends it in a cul-de-sac west of
Alhambra Wash, while north-south streets that might be able to connect with
Whitmore, meanwhile, such as Brighton, Strathmore or Kelburn, are themselves
terminated before they get to Whitmore.
The area on the north side of Garvey Avenue between Del Mar and San Gabriel
Boulevards, the former Los Angeles Auto Auction site, is particularly disconnected,
with too few intersecting streets, highlighting the need for better connectivity with
any development of the site. A resident wishing to walk to Garvey Avenue who
lives in the middle of Whitmore Avenue, less than 0.2 miles from Garvey Avenue as
the crow flies, for example, is forced to walk around the long block, a distance of
nearly three-quarters of a mile. If Kelburn Street extended north of Garvey Avenue
and went through to Whitmore, by contrast, a short walk would be all that was
needed to reach the front of the existing Auto Auction buildings.
Blocks vary in size, but in general are so large that they are not pedestrian-scaled
for easy walkability. For high walkability, block lengths of no more than 300 feet
are preferred. Blocks of 600 feet or more are too large and create long distances to
access close-by areas on foot. The closest thing to pedestrian-scaled blocks along
the Garvey Avenue corridor are those just southeast of the Garvey and New
Avenues intersection, which are 300 by 600 feet. Other block sizes along the
corridor include 300 by 1,000 feet; 375 by 1,250 feet; 400 by 750 feet; 450 by 900
feet. The massive “superblock” encompassing the former Los Angeles Auto Auction
site measures 2,600 by 800 feet. All of these sizes are too large, and discourage
pedestrian activity.

Parcel Pattern
The Specific Plan area displays an overall lot structure with two contrasting parcel
patterns (see Figure 3.3). Within the project area, the parcels vary widely, from as
small as 25 by 100 feet to as large as 640 by 750 feet (Richard Garvey
Intermediate School). Even larger is the former Los Angeles Auto Auction site.
Outside the project area, a relatively homogeneous and fine-grain parcel pattern
exists for the surrounding residential areas; a typical parcel in this area is 50 by
200 feet. Some larger parcels can be seen along New and San Gabriel Boulevard
corridors, for commercial development. Therefore, overall there are many more
trapezoidal parcels than in any other area of Rosemead. The parcel map reveals
one irregularity: the non-rectangular diagonal parcel line following Alhambra Wash.
Building Pattern
The building pattern (Figure 3.4) reveals a striking incongruity: buildings are seen
to be denser in the adjoining single-family housing areas, and less dense in the
commercial area along the Garvey Avenue corridor itself. Most residential buildings
follow rectilinear alignments in response to the rectilinear city grid. Residential
buildings are fine grained and irregular in shape, but generally do not have
significant space around them. They closely follow the street configuration.
Commercial uses along Garvey Avenue, on the other hand, have large building
footprints with lots of space around them, which is used as surface parking. This
incongruous building pattern is the reverse of what would be expected in an area
with more low-density residential neighborhoods surrounding a strong commercial
corridor, but is easier to understand when one considers that most commercial
development is auto-oriented, with surface parking lots covering large swaths of
land. The vast majority of “white space” is either vacant land or surface parking
lots.
The street definition is not strong due to an extremely discontinuous building edge.
That is, the building pattern along the sidewalk is irregular and broken up by
parking lots and driveways, with many “gaps” in the “street wall,” the fabric of
buildings that directly line the sidewalk. This is again due to the auto-orientation
and scale, and the need for car parking. Figure 3.5 shows these large gaps in the
street wall, seen in red. Figure 3.6 shows a comparative example at the same
scale, Main Street in downtown Alhambra, which exhibits some similar gaps in its
street wall, but overall is much more complete, as seen by the relative lack of red.
This type of building pattern has a profound impact on the streetscape and
pedestrian environment. Finally, Figure 3.7 highlights examples along Garvey
Avenue where the gaps in the streetwall have a negative pedestrian experience,
contributing to poor safety, an unpleasant shopping environment, and little design
continuity.

Development Character
Along Garvey Avenue a few larger office buildings with stone, shingle, and concrete
facades occur, but most development is single-story and of fair building quality.
Basic cinderblock or concrete garage-like auto repair shops are common, lending
the corridor a distinctly “light industrial” character. Some mini-malls are built to a
higher standard of quality than other development. Other developments along the
corridor include strip shopping centers, fast-food restaurants, grocery stores, and
larger commercial strip areas. Given that most of the commerce is Asian-oriented,
with business signs in Chinese common, the corridor has a distinctly Asian feeling.
The residential areas surrounding the Garvey Avenue Corridor Specific Plan area are
characterized by low-slung ranch homes. They tend to be low and wide, single-
story houses with street-facing garages and paved driveways and parking areas.
Fencing is common along the property line at the sidewalk. Figure 3.8 shows
examples of typical development along the corridor.

Technical Memoranda Compendium
Views, Gateways, and Landmarks
Views
Rosemead’s location in the San Gabriel Valley provides views to the scenic San
Gabriel mountain ranges that can be stunning. The mountains not only provide an
attractive natural frame to the City, but also provide an element of uniqueness and
contribute to the area’s sense of identity. Furthermore, views of the mountains
provide a constant resource for physical orientation and direction. Views of the
mountains can be seen on Garvey Avenue’s south side, at or near intersections,
and along two potential greenway corridors, Alhambra Wash within the project
area. Figure 3.9 shows key views along the corridor.
On Garvey Avenue itself, views vary considerably. Where there is no median, and
where street tree planting is sparse and trees small, the view is not one to savor
and there is little unique to appreciate. In a few places, however, when looking
directly at an urban forest of median pine trees and majestic sidewalk Eucalyptus
trees, views down Garvey Avenue can be lovely and special, and begin to create a
sense of a special, cared-for street that one would want to live and shop along.
These places are few now, but provide strong clues for how to improve the
streetscape.
Gateways
Gateways are public visual or ceremonial entryways. Improving and adding
gateways into the City along Garvey Avenue (Figure 3.10) can reinforce the City’s
unique identity and sense of place by announcing a threshold or a passage into a
special place, and by creating a sense of arrival. Despite the existence of many
unique neighborhoods and destinations in the City, opportunities for gateways
along Garvey Avenue have not been fully realized. Furthermore, the sense of arrival
in Rosemead from adjoining cities is not distinctive and has the potential for
enhancements.
An existing gateway is located on Garvey Avenue at the entry from City from
Monterey Park at Garvey and New Avenues. Since it is little more than a median
sign, however, it is intended largely for vehicles, and as such this gateway can be
improved for pedestrians. Alhambra Wash right-of-way has the potential to serve
as gateways where it meets Garvey Avenue.
Landmarks
Garvey Avenue’s major landmarks are another key element to establishing
orientation within the area as well as a sense of identity and place. Some of the
corridor’s landmarks may be historic in nature. Landmarks can provide design
direction and inspiration for new developments, anchor particular area with strong
iconic design, and contribute to the design structure of the City. Figure 3.11 shows
some key landmarks within the project area.

Technical Memoranda Compendium
Richard Garvey Intermediate School
This public school, part of the Garvey School District, is located on a large parcel
directly on the south side of Garvey Avenue between Jackson and Evelyn Avenues.
What little green space exists on Garvey Avenue within the project area fronts the
school, supported by a retaining wall. The main school building, with an entrance
on Jackson Avenue, was built in 1937 by the Works Progress Administration. A new
gym was built in 2008.
Arlene Bitely Elementary School
This public school, also part of the Garvey School District, is located on a large
parcel south of Garvey Avenue, just southwest of Richard Garvey Intermediate
School. Like Richard Garvey Intermediate School, it has some green space that is
fenced off from the public.
Jim’s Burgers
The iconic pastel sign of Jim’s Burger’s has welcomed hungry travelers on Garvey
Avenue for years. It sits kitty-corner to Richard Garvey Intermediate School and
provides local color and unique context in the face of other cookie-cutter fast-food
development.
Boca Dharma Seal Temple
Located along Del Mar Avenue just north of Garvey Avenue, the Boca Dharma Seal
Temple is a modern Buddhist temple complex whose main building, a distinctive
wooden temple in the Chinese Buddhist style, was recently completed.
The Square Shopping Center
This large retail area, a large parcel on the southwest corner of Garvey and San
Gabriel Boulevards, is a popular and significant shopping destination along Garvey
Avenue. Its prime location and scale, with dozens of small, largely Asian-owned
businesses, make it a striking landmark.

Technical Memoranda Compendium
Corridor and Street Design
The Garvey Avenue corridor serves as key connections within the city and between
neighborhoods for pedestrians, bicyclists, transit users, and automobiles. Although
it is designed primarily for automobiles, it is used today as a multi-modal corridor.
It is a major transit corridor with both a rapid and local bus line. Regular pedestrian
and bicycle activity occurs throughout the day and in spite of the limited pedestrian
and bicycle facilities. This section of the Technical Memorandum provides an
overview of the Garvey Avenue corridor and other key corridor‘s existing design,
such as Del Mar and New Avenues.
The Transportation and Circulation Technical Memorandum includes a technical
analysis from a transportation engineering perspective of the roadways, pedestrian,
and bicycle networks in the City. Corridors, from an urban design perspective, help
to define a city’s “look and feel” while also providing geographic orientation; a
street’s urban design has a major impact on the overall success of the street from a
user and a commercial perspective. A poorly-designed street will not function well
from any users’ perspective; it can be unpleasant for pedestrians, unsafe for
bicyclists, too congested for transit, too dangerous or inconvenient for drivers, or
not welcoming or inviting to shoppers. A well-designed street will allow for all
modes to safely use it, with efficient and convenient accessibility for all modes; will
offer a pleasant and welcoming environment for shoppers and visitors, and will
even be a healthy, safe, and comfortable place to live.
Street Network
Rosemead’s road system moves traffic using all modes both within town and to
adjacent cities. Street types are defined primarily by the streetscape character,
modes of transportation carried, and speed and volume of traffic they carry. Within
Rosemead they include (1) Freeways, open only to automobiles, trucks, and buses;
(2) Major Arterials; (3) Minor Arterials; 4) Collector Streets; and (5) Local Streets.
The various street typologies and their functionality help provide an understanding
of multimodal circulation. Figure 3.12 shows the street network and hierarchy
within the Specific Plan area.
In addition to the street types are the regional highways, such as I-10, SR- 60, and
Rosemead Boulevard. These highways connect Rosemead regionally but also pose
significant barriers within the City to pedestrians and bicyclists as they divide
neighborhoods.

Rosemead Garvey Avenue Page 3-23
Technical Memoranda Compendium
Garvey Avenue is one of four major arterials within the City of Rosemead, as is
San Gabriel Boulevard, which runs north-south at the eastern end of the Specific
Plan Project Area. New Avenue and Del Mar Avenue are minor arterials. The other
streets within the project area are local streets. Most of Rosemead’s major arterials
are through-streets that crosscut through the city and connect with other cities and
freeways. Local streets tend not to extend throughout the city, but are localized to
certain neighborhoods. Often this disjointed layout presents a challenge, in
particular, to pedestrian and bicycle circulation, because bicyclists who might prefer
a quieter neighborhood street cannot take the street very far without becoming
blocked.
As defined in the Transportation Element of Rosemead’s General Plan, “the function
of a Major Arterial is to connect traffic from minor arterials and collectors to other
parts of the city, freeway interchanges, and adjacent major land uses. They are the
principal urban thoroughfares and provide a linkage between activity centers in the
City and to adjacent communities. Major Arterials are designed to move large
volumes of traffic, typically in the range of 40,000 to 60,000 vehicles per day. They
are generally served by regional transit routes and are the primary truck routes in
the community.”1 This street definition makes clear that major arterial streets like
Garvey Avenue “are designed to move large volumes of traffic.” They are not
designed, in other words, to be a welcoming place for pedestrians, nor are they
designed for bicyclists, or even for transit (they merely are “served by” transit).
In Rosemead, however, major arterial streets like Garvey Avenue are asked to be
much more than simply through a corridor for thousands of vehicles. They are not
freeways, with their own separate right-of-way. They have many other functions
other than moving large numbers of cars. They must move pedestrians, and move
them safely. Some of the major arterials, including Garvey Avenue, must move
transit efficiently, and provide stopping space for buses and waiting space for
transit users. They also must serve as public gathering space in front of key
neighborhood nodes. They must be the “front yard” for those who live directly on
it. They must move bicyclists. Finally, in Rosemead, it is crucial to note that major
arterials like Garvey Avenue also are designated the city’s primary commercial
areas. The stated goals of improving Rosemead’s commercial corridors, by reducing
strip development and using good urban streetscape design and high-quality
development to make them more attractive and pedestrian-friendly places to live
and shop, can often run counter to the goals of vehicle throughput. In Rosemead’s
General Plan, these stated goals include:
Policy 2.2 of the Land Use Element: Revitalize commercial strip corridors by
creating attractive and dynamic pedestrian-friendly activity nodes and
commercial centers;
Policy 3.1: Encourage mixed-use development as a means of upgrading
established uses and developing vacant parcels along arterials and providing
new commercial, residential, and employment opportunities;
1 Rosemead General Plan Update, page 3-4.
Urban Design
Page 3-24 Rosemead Garvey Avenue
Technical Memoranda Compendium
Policy 3.4: Encourage pedestrian friendly commercial and residential planned
developments wherever possible; and
Policy 3.5: Promote lively and attractive ground-floor retail uses that will
create public revenues needed to provide for City services and the City’s tax
base.2
It is challenging for any street to provide “attractive and dynamic pedestrian-
friendly activity nodes” and “lively and attractive ground-floor retail” when there are
50,000 cars in multiple lanes of traffic passing by just a few feet away. Garvey
Avenue is a prime example of this inherent conflict. For Garvey Avenue to continue
to serve as a major vehicle corridor, with steady or even increasing amounts of
heavy vehicle traffic, and yet at the same provide an enhanced and more
welcoming and inviting pedestrian and shopping environment, safe for all users, will
be a challenging balancing act that will require difficult choices and constant
weighing of benefits and trade-offs. It will need, first and foremost, to be designed
specifically for pedestrians and for street retail shopping, and for bicycle
accessibility; simply allowing these uses on a street designed instead to move large
volumes of traffic is not likely to be successful. Still, while it is undoubtedly difficult
for a street like Garvey Avenue that carries heavy vehicle traffic to also be one that
welcomes pedestrians to stroll and shop on the sidewalks, provides safe facilities for
bicyclists, and is a healthy and pleasant place to live, it is not unheard of or
impossible. The keys to making Garvey Avenue’s transformation possible are
careful attention to urban design together with thoughtful, high-quality land use
development. Most important, it must be redesigned specifically for these uses,
with pedestrians foremost in mind.
A minor arterial street is defined in Rosemead’s General Plan as an “intermediate
route carrying traffic between local streets and major arterials. They are designed
to carry moderate levels of traffic, generally in the range of 15,000 to 25,000
vehicles per day.”3
New and Del Mar Avenues are minor arterial streets in the Specific Plan area. While
New Avenue within Rosemead is primarily residential, Del Mar Avenue, like Garvey
Avenue, is primarily commercial, and shares many of the same challenges in
enhancing it for pedestrians and improving street retail while also serving
thousands of cars. Like Garvey Avenue, it serves bicyclists poorly but is prioritized
for a dedicated bicycle facility in the Bicycle Improvement Plan.
A local street is a neighborhood street with low traffic volumes. Unlike major and
minor arterials, which the General Plan says are designed to move vehicles, local
streets “are designed to principally provide vehicular, pedestrian, and bicycle access
to individual parcels throughout the city.”4 Residential neighborhoods, schools and
parks in Rosemead are primarily accessed by local streets. All streets within the
Specific Plan area, other than Garvey Avenue, San Gabriel Boulevard, Del Mar

Avenue, and New Avenue, are local streets, such as Jackson Street, Evelyn Avenue,
and Denton Avenue.
Garvey Avenue
The following section discusses the existing conditions and design of Garvey Avenue
in detail. It is a significant street within Rosemead and the focus of the Garvey
Avenue Corridor Specific Plan; history has fashioned it into a street with its own
particular character. Garvey Avenue is centrally located within Rosemead. It is the
largest and main east-west street south of I-10, mirroring Valley Boulevard on the
side of Rosemead north of I-10. By virtue of its location and size, Garvey Avenue
serves as the social and civic core of the southern half of Rosemead. Some redesign
efforts have taken place on Garvey Avenue in Rosemead in recent years, notably
the creation of green medians along certain portions. Significant efforts have been
made on other portions of its length, notably in downtown Monterey Park, just west
of the project area. A focus of the Garvey Avenue Corridor Specific Plan is to help
the street become a more livable place and attractive shopping destination for the
city with attractive urban design components that foster a strong pedestrian
environment.
Along many sections of Garvey Avenue, many buildings tend to be set back from
the street and separated by parking lots or driveways. Buildings are typically
between one to two and stories in height, with one-story buildings being the most
common. The lack of a clear and consistent line of buildings along the sidewalks, or
street wall, to help enliven the street and engage pedestrians has negative
consequences: these irregular edge conditions contribute to the overall sense of an
environment that caters to vehicles and not pedestrians. Where there is more than
one-story, buildings tend to have good design differentiation between the bottom
and upper floors of the building. When buildings directly line the street, entries are
generous and often have awnings. Since many buildings do not front the street,
however, many entries are set back far from the sidewalk and are auto-oriented in
scale. Few shop windows are open, bright, and inviting, however, and many
buildings shade their windows and turn away from the street, rather than embrace
it and open onto it.
Garvey Avenue today has some special design elements that help make portions of
it lovely – certainly much better than it would be without these elements. In
particular, the majestic and massive Eucalyptus trees that line portions of its
sidewalks are a special and unique element that should be preserved and
enhanced. They enhance the streetscape and pedestrian environment, provide
needed shade and air-quality benefits, and help calm traffic. In a few areas of the
corridor, there is also a planted median, which contributes even further to these
benefits, but the median is only present sporadically, and where it is not present,
safety, comfort, and attractiveness suffer. The Eucalyptus street trees, moreover,
are not consistently planted throughout the corridor, and many are not healthy and
need room to grow (a full arborist’s assessment of these majestic trees is
recommended). On the rare blocks of Garvey Avenue that have both large street
trees and a planted median with tall trees, these features greatly enhance the
Urban Design

streetscape, improve the street as public space, and offer significant traffic-calming
benefits. Figure 3.13 shows the existing streetscape design on Garvey Avenue.
Currently, most of the Garvey Avenue right-of-way is dedicated to vehicles, with
disproportionately little space dedicated to pedestrians and bicycles. The right-of-
way is 100 feet wide. There are a total of four travel lanes—two in each direction—
and two parking lanes, stretching 76 feet in total. For small portions of its length, a
10-foot wide center median separates the westbound and eastbound traffic;
elsewhere the median is not present and the middle 10’ become a center turn lane.
The landscaped center median is landscaped with shrubs, groundcovers, trees, and
conifers. Sidewalks on each side are on average twelve feet wide and are lined with
street trees, either large and mature or newly planted. Other amenities and
furnishings that could improve the pedestrian experience, such as pedestrian-scale
lighting, seating, and other street furniture, are limited. In many areas, on-street
parking is underutilized, which is, perhaps, not surprising given the number of off-
street parking lots. Figure 3.14 shows an existing cross-section of Garvey Avenue.
Traffic volumes on Garvey Avenue compete with and detract from the pedestrian
environment. Besides street trees and the intermittent green median, there are
few traffic-calming measures to ensure that vehicles move at a comfortable speed
for all users of the street. The many surface parking lots encourage people to drive
rather than walk to the corridor. The many surface parking lots also deaden street
life. There are few pedestrian crossings, spaced much too far apart to provide safe
and easy pedestrian access to both side of the street. At intersections, crosswalks
are set by default to red for pedestrians, prioritizing vehicle movement and forcing
pedestrians to press a button to safely cross the street. Garvey Avenue’s design
also discourages pedestrian circulation due to infrequent crossings as a result of the
long blocks on either side. Pedestrian crossings are only allowed at major
intersections, with no midblock crossings, creating long distances for pedestrians to
traverse.
Conditions for bicyclists are poor. There is no dedicated facility for bicyclists; many
bicyclists choose to ride on the sidewalk for safety. In spite of the lack of bicycle
facilities, bicycle ridership on Garvey Avenue is relatively high. Indeed, Rosemead’s
Bicycle Improvement Plan found that Garvey Avenue had the most bicycle ridership
of any street in the city of Rosemead. Unfortunately, Garvey Avenue does not move
bicycle riders safely; the Bicycle Improvement Plan found that nearly one quarter of
the reported bicycle collisions that occurred in the city from 2007-2011 were on
Garvey Avenue, “likely due to its high use as a bikeway for east-west travel south
of I-10 and its lengths.”5 The Plan made the installation of a dedicated bicycle
facility on Garvey Avenue its top priority. Figure 3.15 shows the transit, pedestrian
and bicycle environment on Garvey Avenue.
Rapid and local transit along Garvey Avenue, with no dedicated lanes, is forced to
compete with private vehicle traffic, and is given little priority. While there are bus
shelters on the sidewalks, there are few other amenities for transit users.

Technical Memoranda Compendium
Key Findings
Vehicles dominate the right-of-way. Not only is the corridor designed
primarily for cars, a large percentage of the businesses are auto-related.
Accordingly, conditions for pedestrians, transit riders, and bicyclists are poor.
This is true even though Garvey Avenue is a major transit corridor with both
a local and a rapid bus line; even though there are already a good number of
pedestrians using the sidewalks and crossing the wide intersections; and
even though there is a steady stream of bicyclists, most of who are forced to
ride on the sidewalk. Addressing these deficiencies to make the corridor a
safer and more walkable and transit- and bike-friendly place will be critical to
its transformation and future growth – especially if the corridor develops as
more mixed use, with more people living directly on the corridor itself.
Garvey Avenue’s role as a “cut-through” route for vehicles attempting to
avoid or bypass the parallel I-10 diminishes its ability to serve as a safe and
pleasant gathering place, shopping area, and neighborhood street. If
significant development along Garvey Avenue is anticipated, the necessity of
maintaining Garvey Avenue as a major “cut-through” street for vehicles
should be reevaluated.
Pedestrian and bicycle connections to key destinations in adjoining
neighborhoods should be established and/or enhanced to provide convenient
access for all modes of travel. Sidewalks with street trees and planting strips
can provide a safer and more comfortable pedestrian environment, while
dedicated bicycle facilities are needed to improve safety and comfort for
bicyclists already on Garvey Avenue, and to encourage more bicyclists.
The land along Alhambra Wash (and the Wash itself) is a particular
opportunity for new green space along an underutilized water body. Former
concrete channels are being re-imagined in Los Angeles, the LA River being
the most visible, and a similar effort for Alhambra Wash could help catalyze
development in the area and be something Rosemead could be a leader on
and become known for. Working with landowners and developers to integrate
high quality public open space along the Wash into their development
planning can greatly enhance the corridor.
There are no community gathering places, few vibrant public spaces, and few
landmarks that serve as iconic elements and provide a unique identity for the
Garvey Avenue corridor. These elements are needed to make the street a
real place.
Several private mini-malls provide commercial anchors at regular intervals,
all along the south side of the street, and should be encouraged to grow into
more pedestrian-friendly plazas that add to and enhance the public realm.

Rosemead Garvey Avenue Page 3-31
Technical Memoranda Compendium
Some street trees – especially Eucalyptus – are large and stately and are
among the corridor's best assets. Many are also in poor shape, however, and
need more room to grow, which will mean expanding these trees’ sidewalk
footprint. In some places, the trees have been planted in an alternating,
staggered fashion along street-side and then along the building edge. It
makes sense to respect this unusual street tree design plan and work with it
to help enhance the pedestrian and active transportation environments.
An occasional existing green median is a major asset, but is discontinuous
and nonexistent in a number of places.
Views towards the San Gabriel Mountains emphasize the uniqueness of the
corridor and offer a special sense of place in Rosemead, as well as provide
physical orientation and direction. Opportunities exist to create and enhance
well-designed gateways that frame the mountains and reinforce the
corridor’s unique identity and sense of place.
The community values the many single-family residential neighborhoods’
character, which abut the project area on all sides, and opportunities exist to
preserve and enhance these areas. Opportunities also exist to consider
changes to the character of specific areas over the life of the Specific Plan.
How to incorporate new uses into the corridor in an appropriate and
compatible way, such as mixed-use development or higher-intensity
residential development, will be a key issue in the Specific Plan.

Existing Roadway System
Interstate 10 (also known as the San Bernardino Freeway) is an east-west regional
freeway, providing access directly to roadways within the project area. Near the

Analysis
Traffic Analysis Methodology
Key tasks undertaken for this existing conditions traffic analysis include definition of
study approach and determination of existing traffic conditions. A subsequent
expanded traffic report will include the following: trip generation forecasts of the
planned Specific Plan land uses, assignment of Project-generated trips to the study
area roadway system, and evaluation of the impact of cumulative traffic at the
study intersections.
This memorandum follows guidelines within the City of Rosemead document
Transportation Impact Analysis Guidelines.1 Traffic study guidelines defined by the
City of Monterey Park2 were incorporated into the analysis of the study intersection
that is located on the border of the City.
Weekday a.m. and p.m. peak-hour traffic operations are evaluated for the existing
(year 2014) conditions at the study intersections.
Intersection Operations
The analysis of peak hour intersection Level of Service (LOS) is the primary
indicator of circulation system performance. For the analysis of the study area
intersections, the City of Rosemead requires that the Intersection Capacity
Utilization (ICU) Method procedure be used.
ICU calculations used to determine the intersection volume-to-capacity ratio (V/C)
and corresponding LOS were based on the turning movements and intersection
characteristics at the signalized intersections. The methodology calculates the V/C
ratio based on a default capacity [C] per lane, usually 1,600 vehicles per hour (vph)
per lane and 2,280 vph for dual turn lanes. The total intersection loss time of 10
seconds was applied to the V/C ratio.
The concept of intersection level of service is calculated as the volume of vehicles
that pass through the facility divided by the capacity of that facility. A facility is “at
capacity” (v/c of 1.00 or greater) when extreme congestion occurs. This
volume/capacity ratio value is based upon volumes by lane, lane capacity, and
approach lane configurations.
Level of service (LOS) values range from LOS A to LOS F. LOS A indicates excellent
operating conditions with little delay to motorists, whereas LOS F represents
congested conditions with excessive vehicle delay. LOS E is typically defined as the
operating “capacity” of a roadway. Significant traffic impacts, the focus of this
study, are defined using separate thresholds based on operational changes and
multiple level of service values.
Traffic and Circulation
Rosemead Garvey Avenue Page 4-7
Technical Memoranda Compendium
Table 4.2 defines the Highway Capacity Manual3 LOS value ranges, based on
volume/capacity ratio for signalized intersections.
LOS E conditions denote near-capacity conditions, while LOS F conditions denote at-
capacity or over-capacity conditions.
Table 4.2
Level of Service Range Definitions

Service Flow Conditions
Volume

Ratio
A LOS A describes primarily free-flow operation. Vehicles are
completely unimpeded in their ability to maneuver within the
traffic stream. Control delay at the boundary intersections is
minimal. The travel speed exceeds 85% of the base free-flow
speed.
0.00-
0.60
B LOS B describes reasonably unimpeded operation. The ability to
maneuver within the traffic stream is only slightly restricted and
control delay at the boundary intersections is not significant.
The travel speed is between 67% and 85% of the base free-
flow speed.
0.61-
0.70
C LOS C describes stable operation. The ability to maneuver and
change lanes at midsegment locations may be more restricted
than at LOS B. Longer queues at the boundary intersections
may contribute to lower travel speeds. The travel speed is
between 50% and 67% of the base free-flow speed.
0.71-
0.80
D LOS D indicates a less stable condition in which small increases
in flow may cause substantial increases in delay and decreases
in travel speed. This operation may be due to adverse signal
progression, high volume, or inappropriate signal timing at the
boundary intersections. The travel speed is between 40% and
50% of the base free-flow speed.
0.81-
0.90
E LOS E is characterized by unstable operation and significant
delay. Such operations may be due to some combination of
adverse progression, high volume, and inappropriate signal
timing at the boundary intersections. The travel speed is
between 30% and 40% of the base free-flow speed.
0.91-
1.00
F LOS F is characterized by flow at extremely low speed.
Congestion is likely occurring at the boundary intersections, as
indicated by high delay and extensive queuing. The travel speed
is 30% or less of the base free-flow speed. Also, LOS F is
assigned to the subject direction of travel if the through
movement at one ormore boundary intersections has a volume-
to-capacity ratio greater than 1.0.

Existing Roadway Conditions
The analysis of operations at the study intersections was conducted for weekday
a.m. and p.m. peak-hour conditions. New traffic counts were conducted for this
study in May 2014.
The results of the analysis of existing weekday a.m. and p.m. peak-hour
intersection LOS analysis are summarized in Table 4.3. All of the study
intersections operate at good LOS values D or better under the existing conditions.
At the intersections of San Gabriel Boulevard/Garvey Avenue and Walnut
Grove/Garvey Avenue, LOS D conditions are approaching LOS E (near-capacity)
conditions.

Existing Freeway Conditions
The existing freeway mainline level of service (LOS) analysis for the nearby I-10
used information from the Caltrans website to determine existing average annual
daily traffic (AADT) volumes, directional flow count data, and peak-hour factoring.
The relevant Caltrans5 reports are the 2012 Traffic Volumes Book and the 2012
Peak Hour Volume Data report.
The results of the existing LOS calculations are summarized in Table 4.4 below.
The LOS values are based on volume and lane inputs and the density of traffic in
the peak hour and peak direction.

Existing Public Transportation Conditions
Public transportation in the study area, as defined here, consists of fixed route bus
service and dial-a-ride service. This latter type of service is an advance
reservation, shared ride transportation service for senior residents or disabled of
any age and their attendants. Existing local bus transit services that collectively
provide viable alternatives to use of the private automobile are discussed below.
The study area is served by bus transit lines operated by the Los Angeles County
Metropolitan Transportation Authority6, City of Rosemead7, and City of Montebello8.
Table 4.5 summarizes the service characteristics of the existing transit lines within
the study area and Figure 4.5 illustrates the routes of these lines.

Introduction
5 x
This memorandum summarizes the existing sewer infrastructure system within the
Garvey Avenue Corridor Specific Plan area as analyzed by Land Design Consultants
in August 2014, see Appendix B for the complete analysis. This memorandum
determines the capacity of existing sewer reaches from the assumed development
potential to the several Sanitation Trunk systems within the City of Rosemead.
Analysis
The Garvey Avenue corridor land use consists of multi-family residential uses,
school use, mixed commercial/office uses, mixed use commercial/industrial uses,
and light manufacturing uses.
The Garvey Avenue Corridor Specific Plan is anticipated to provide for new
commercial and residential development in a vibrant corridor with visible,
pedestrian friendly activities. For the purposes of the sewer analysis, development
buildout capacity was estimated based on existing uses, proposed development
applications, and zoning designations.
Existing sewer pipes within the study area (Figure 5.1) have been analyzed. The
majority of the existing pipes are 8 inch diameter with varied slopes along the flow
path which then connects to downstream sewer trunk connections. This particular
study has five sewer trunk connections.
The study areas between New and Del Mar Avenues have been analyzed. There are
two existing 8” sewer lines on both sides of Garvey Avenue within this area that
account for discharge flows which is then collected downstream to a 36” trunk
sewer. Based on the existing buildout assumptions described above, the sewers
downstream will have inadequate capacities and will have to be upsized.
The study area between Del Mar Avenue and San Gabriel Boulevard has been
analyzed in the same manner. There are two existing 8” sewers on both sides of
Garvey Avenue that are collected and discharged downstream to a 27” trunk sewer.
The sewers within this area have adequate capacities. However, should future plan
multi-story high density developments with such as hotels, multi-family residential
housing or multi-family mixed use buildings be proposed, the project’s demand may
exceed capacity.
The remaining study areas between San Gabriel Boulevard and Charlotte Avenue
area have been analyzed. These areas are tributary to 8” sewer lines along San
Gabriel Boulevard and Garvey Avenue and discharged downstream to 21” trunk
sewer. The areas to the north and south of Garvey Avenue have adequate
capacities to the 8” sewer line along Garvey Avenue.

However, the 8” sewer line along San Gabriel Boulevard between Garvey Avenue
and Park Street has inadequate capacity and will have to be upsized.
Currently, the some of the existing sewers within the study areas show deficiencies
in capacity. This has been identified in the sewer area report prepared in 1996 for
the City of Rosemead and particularly located along Del Mar Avenue between
Garvey Avenue and Emerson Avenue.
In addition, a sewer system management plan was prepared in 2009 for the City of
Rosemead. An extensive analysis was made of the city’s entire sanitary collection
system and a rating system was developed for maintenance and structural defects
of all the sewer pipe segments. Defects requiring immediate attention are
particularly located along Garvey Avenue between Brighton Avenue and Strathmore
Avenue.
Sewer Design
Based on the L.A. County Department of Public Works Land Development Division’s
Sewer Area Study requirements, the existing sewer pipe reaches are flowing at
maximum pipe capacity when they are all flowing at one half-full for pipes with
diameters smaller than 15 inches. The as-built sewer plans were used to determine
the slopes; pipe sizes for the study area are listed in sewer area study tables and
maps, all of which are contained in Appendix B.
The anticipated sewer discharge flow rates were calculated for various sewer line
reaches from Kutter’s Formula with “n=0.013” by using the Flow Master Computer
programs.
The discharged flow rates (Q) were calculated by using the Zoning Method. The
anticipated land use of the properties within and around the study limits were
determined by the City of Rosemead’s Zoning Map, Garvey Specific Plan planning
area map, and the proposed development projects. For the potential developments
without data, flows were based on the zoning map and zoning coefficients for
ultimate build-out. For the known proposed development sites, production flows
were generated based on building square footage and dwelling units. The Zoning
Coefficients are the current L.A. County’s sewer area study flow coefficients.
Key Findings
Some of the study areas’ existing sewers show capacity deficiencies. The
deficiencies were noted in a 1996 City of Rosemead sewer study; the
deficiencies occur on Del Mar Avenue between Garvey Avenue and Emerson
Avenue. These facilities will need to be upgraded to a larger pipe size.
Some of the study areas’ existing sewer show maintenance and structural
defects. The defects were noted in a 2009 City of Rosemead Sewer System

Management Plan; the deficiencies occur on Garvey Avenue between
Brighton Avenue and Strathmore Avenue. These facilities will need to be
replaced with a new pipe.
Analysis for the Garvey Avenue Corridor Specific Plan shows additional
capacity issues based on an assumed buildout projection. The over capacity
pipes are the reaches along Del Mar Boulevard to the 36” trunk connection at
Emerson Avenue (New Avenue/Del Mar Avenue study area); the reaches
along San Gabriel Boulevard to the 21” trunk connection (San Gabriel
Boulevard/Garvey study area). Further analysis is required as development is
considered and proposed.

Introduction
6 x
This memorandum summarizes the existing water infrastructure system within the
Garvey Avenue Corridor Specific Plan area as analyzed by Land Design Consultants
in August 2014. The full water infrastructure memorandum and analysis is included
in Appendix C.
State Resolution No. W-4976
In the recent years, the State of California has been experiencing dry weather
conditions due to less rainfall in the area, thus, causing a state wide drought
emergency. In an effort to promote water conservation effort, Resolution No. W-
4976 was adopted by the California Public Utilities Commission on February 27,
2014 to establish procedures for water conservation measures in order to ensure a
reduction in consumption. Since many water utility agencies or companies secure
their water supply from multiple sources, including water wholesaler, surface water
and/or ground water; the adoption of the this mandate has affected how water
utility districts plan their service distribution while encountering various levels of
water supply adjustments within each service areas.
Analysis
The Garvey Avenue corridor land use consists of multi-family residential uses,
school use, mixed commercial/office uses, mixed commercial/industrial uses, and
light manufacturing uses.
The Garvey Avenue Corridor Specific Plan is anticipated to provide for new
commercial and residential development in a vibrant corridor with visible,
pedestrian friendly activities. For the purposes of the water supply analysis,
development buildout capacity was estimated based on existing uses, proposed
development applications, and zoning designations. The development buildout
includes:
Garvey Avenue between New Avenue and Del Mar Avenue segment -
commercial use designation, proposed supermarket application, and existing
school designated as public facilities
Garvey Avenue between Del Mar Avenue and San Gabriel Boulevard segment
- mixed use retail/commercial designation, office use, light industrial use,
and light manufacturing use. In addition, the former Auto Auction site is
designated as regional commercial, while another site located at the
northeast corner of Del Mar Avenue and Garvey Avenue is anticipated to be a
mixed-use development. Garvey Avenue between San Gabriel Boulevard and
Charlotte Avenue segment- commercial use designation.

Water Source/Supply
The domestic water supply within the City of Rosemead is served by six water
suppliers: Adams Ranch Mutual Water Company, Amarillo Mutual Water, California
American Water, Golden State Water Company, San Gabriel County Water District,
and San Gabriel Valley Water. The Garvey Avenue Corridor Specific Plan area is
within the Golden State Water Company’s (GSWC) service area, also known as the
South San Gabriel System, as illustrated on Figure 6.1. The make-up of the service
area is primarily characterized residential, mixed commercial, and office uses.
GSWC obtains its water supply from two major sources: imported water from
Metropolitan Water District of Southern California, and GSWC operated groundwater
wells located within the Rosemead service boundary. In the GSWC’s 2010 Urban
Water Management Plan- South San Gabriel System, the availability of water from
each source is estimated through the year 2035, as shown in Table 6.1.

Based on projected use in the Main San Gabriel Groundwater Basin. 2015-2035
groundwater projections assume a long-term average OSY of 190,000 ac-ft.
Using the buildout scenarios described above and based on the GSWC 2010 Urban
Water Management Plan and Land Design Consultants’ discussions with the Golden
State Water Company representatives, GSWC anticipates that future water
demands can be met until 2035. GSWC understands that development within the
service area may increase above the existing zoning. That being said, the water
lines along Garvey Avenue have the most capacity for potential increase due to the
12” main fronting the Garvey Avenue parcels.

Infrastructure
Within the Garvey Ave Specific Plan boundary, the existing Garvey Avenue water
line is served by three segments of 6”, 8”, and 12” mains as indicated on Figure
6.2. The following summarizes the existing size and locations of the water mains at
each section of Garvey Avenue:
Between New Avenue and Jackson Avenue (Figure 6.3):
Two water mains located in this portion of Garvey Avenue serve existing uses on
both sides of Garvey Avenue. Specifically, a 6” ci main located north of the
centerline, and a 12” pvc main located south of the center line. New Avenue,
located on the westerly end of the Specific Plan area, is currently served by a 10”
pvc main north of Garvey Avenue and a 12” pvc main south of Garvey Avenue. The
side streets -- Dequine Avenue, Lindy Avenue, Prospect Avenue, and Jackson
Avenue are served by a 6” pvc or 8” pvc main.
Between Jackson Avenue and Del Mar Avenue (Figure 6.4):
Garvey Avenue is served by an 8” ci main located northerly of the centerline.
Evelyn Avenue, a side street, is served by an 8”ci main and Del Mar Avenue is
served by a 10”ac main.
Between Del Mar Avenue and Charlotte Avenue (Figure 6.5):
Garvey Avenue is served by a 12” ac main located north of the centerline from Del
Mar Avenue to Denton Avenue and a 12” pvc main located south of the centerline
from Denton Avenue to Falling leaf Avenue and a 12” stl (cl) from Falling Leaf
Avenue to Charlotte Avenue. San Gabriel Boulevard is served by a 8”ci main south
of Garvey Avenue and a 10” pvc main north of Garvey Avenue. The side street,
Brighton Avenue, is served by a 8”ci main south of Garvey Avenue and a 8” pvc
main northerly of Garvey Avenue; Strathmore Avenue is served by a 8” ac or di
main; Denton Avenue is served by a 12” ac main; Kelburn Avenue, Falling Leaf
Avenue & Pine Street are served by a 6” ci main; Gladys Avenue is served by a 6”
pvc main; Lotte Avenue is served by a 8” pvc main, and Charlotte Avenue by a 8”
ac main.
The existing water pressure, under normal daily operations, will range from about
40 psi to 85 psi. The pressure gradually goes up from New Avenue to Charlotte
Avenue. The elevation at New Aveune is at approximately 360 feet with a gradual
decline to approximately 265 feet in elevation at Charlotte Avenue. These water
lines are the main feeds to provide water service to the Specific Plan Area and
would also provide sufficient capacity to serve the development limits based on the
buildout assumptions provided above.

This memorandum summarizes the existing storm water drainage infrastructure
within the Garvey Avenue Corridor Specific Plan area as analyzed by Land Design
Consultant in August 2014. The full storm water drainage infrastructure
memorandum and analysis is included in Appendix D.
Analysis
The Garvey Avenue corridor land use consists of multi-family residential uses,
school use, mixed commercial/office uses, mixed commercial/industrial uses, and
light manufacturing uses.
The Garvey Avenue Corridor Specific Plan is anticipated to provide for new
commercial and residential development in a vibrant corridor with visible,
pedestrian friendly activities. For the purposes of the storm water drainage
analysis, development buildout capacity was estimated based on existing uses,
proposed development applications, and zoning designations. The development
buildout includes:
Garvey Avenue between New Avenue and Del Mar Avenue segment -
commercial use designation, proposed supermarket application, and existing
school designated as public facilities
Garvey Avenue between Del Mar Avenue and San Gabriel Boulevard segment
- mixed use retail/commercial designation, office use, light industrial use,
and light manufacturing use. In addition, the former Auto Auction site is
designated as regional commercial. Another site is proposed to be mixed-use
and located at the north-east corner of Del Mar and Garvey Avenues.
Garvey Avenue between San Gabriel Boulevard and Charlotte Avenue
segment- commercial use designation.
The Garvey Avenue Corridor Specific Plan area’s watershed drains into several
drainage systems. The main drainage system is a reinforced concrete (RC) box
culvert that runs along Garvey Avenue to the Alhambra Wash and several reinforce
concrete (RC) pipes drainage systems. The following summarizes the existing
locations and size of the storm drainage facilities at each section of Garvey Avenue.
Between New Avenue and Jackson Avenue (Figure 7.1):
A 11’x13’ reinforced concrete (RC) box culvert located along the Garvey
Avenue centerline.
A 39” RC pipe located along Garvey Avenue then routed to the north along
Prospect Avenue.
Areas to the north and south of Garvey are tabled to various catch basins
(CB) and are connected to the 39” RC pipe. The south-east corner of Jackson
Avenue and Garvey area is tributary RC box culvert at this location.

Between Jackson Avenue and Del Mar Avenue (Figure 7.2):
A RC box culvert (varies in size 11’x13 to 9x11) located south of the Garvey
Avenue centerline.
A 48” RC pipe running in the west-east direction, just north of the Specific
Plan area.
Areas to the south of Garvey Avenue are tabled to the RC box culvert. The drainage
areas to the north of Garvey Avenue are conveyed along Garvey Avenue then
through the side streets to the north to the 48” RC pipe.
Between Del Mar Avenue and Charlotte Avenue (Figure 7.3):
A RC box culvert (varies in size 7’x9 to 12x9) located south of the Garvey
Avenue centerline to the Alhambra Wash
A 24” RC pipe running in the north-south direction along Strathmore Avenue.
A 42” RC pipe running in the north-south direction along San Gabriel
Boulevard.
A 27” RC pipe running in the west-east direction along Garvey Avenue.
A RC pipe (varies in size 30” to 42”) located along Newmark Avenue to the
Alhambra Wash.
The drainage areas on the south of Garvey from the side streets Brighton to Denton
Avenues are tributary to the RC box culvert and the side streets from Kelburn
Avenue to San Gabriel Boulevard are tabled to the RC pipes along Newman Avenue.
The drainage areas on the north of Garvey Avenue from Brighton to the Alhambra
Wash are tabled to the RC Box culvert as well. The area to the north of the
Alhambra Wash and San Gabriel Boulevard is tabled to the 42” RC pipe along San
Gabriel Boulevard. The drainage areas from these storm drains are all collected and
discharged to the Alhambra Wash. The remaining drainage area east of San Gabriel
Boulevard is collected to 27” RC pipe drain system along Garvey Avenue and
discharged east of the Specific Plan area.

1. BACKGROUND
1.1. INTRODUCTION
Framework
The traffic analysis presented in this report was conducted for the Garvey Avenue Corridor Specific
Plan (Project) and the associated environmental documentation. KOA Corporation created this report
for the City of Rosemead, while under a subcontract with MIG. The name "Project" refers to the
proposed Specific Plan within this document.
NOTE: This interim version of the traffic report focuses on existing conditions only.
This traffic analysis documents the methods and results of the analysis of existing circulation conditions
within the Specific Plan Project study area. The expanded traffic report will provide recommendations
regarding physical roadway facility, traffic signal, and transit enhancements, and all elements that are
necessary to adequately accommodate anticipated growth.
Scope of Traffic Impact Study
The scope of the traffic impact study conducted for the Garvey Avenue Corridor Specific Plan update
was developed during coordination efforts with MIG and the City of Rosemead. Based on the
commercial corridors where land uses would primarily change or intensify under the Specific Plan, and
also based on the locations of major roadway intersections, a study area was developed.
The study area includes nine intersections, of which eight intersections are located within the City of
Rosemead, and one intersection is located on the border of the City of Rosemead and the City of
Monterey Park:
1) Del Mar Avenue & Hellman Avenue
2) San Gabriel Boulevard & Hellman Avenue
3) New Avenue & Garvey Avenue *
4) Jackson Avenue & Garvey Avenue
5) Del Mar Avenue & Garvey Avenue
6) Kelburn Avenue & Garvey Avenue
7) San Gabriel Boulevard & & Garvey Avenue
8) Delta Avenue & Garvey Avenue
9) Walnut Grove Avenue & Garvey Avenue
* Located on City border
Significant traffic impacts of development that could result from implementation of the Project land use
plan will be evaluated within the expanded traffic report for the weekday a.m. and p.m. peak periods at
the study intersections.
Figure 1 illustrates the Specific Plan boundaries, in relationship to the area roadway network. Figure 2
illustrates the locations of the study area intersections in relation to the Specific Plan boundaries and the
transportation analysis zones or TAZs used for the land use trip generation analysis.

Analysis Methodology
This section documents the level of service methodologies used to evaluate traffic circulation on the
roadways within the Project study area. A finite study area was chosen that focuses on the key roadway
intersections within the City.
Key tasks undertaken for this traffic analysis included the following: 1) definition of study approach, 2)
determination of existing traffic conditions.
The expanded traffic report will include the following: 3) trip generation forecasts of the planned
Specific Plan land uses, 4) assignment of Project-generated trips to the study area roadway system and,
5) evaluation of the impact of cumulative traffic at the study intersections.
This report follows guidelines within the City of Rosemead document Transportation Impact Analysis
Guidelines1. Traffic study guidelines defined by the City of Monterey Park2 were incorporated into the
analysis of the study intersection that is located on the border of the City.
The following text describes the methodology applied to the traffic analysis.
Study Scenarios
Weekday a.m. and p.m. peak-hour traffic operations were evaluated at the study intersections for the
following traffic scenarios, numbered in this specific manner for discussion purposes. Significant traffic
impacts are determined in the second and fourth scenarios:
1. Existing (year 2014) Conditions
2. Existing plus Project Conditions *
3. Future (2035) Pre-Project Conditions *
4. Future (2035) Post-Proposed Project *
* This is an existing conditions only report. These sections will be analyzed in a later expanded version of this
report.
The City of Rosemead traffic study guidelines define significant impacts by two specific comparisons of
the scenarios defined above:
The incremental change from Scenario 1 to Scenario 2 (Project Impacts)
The incremental change from Scenario 3 to Scenario 4 (Cumulative Impacts)
The City of Monterey Park traffic study guidelines define significant impacts by a single comparison of
these scenarios:
The incremental change from Scenario 3 to Scenario 4 (Cumulative Impacts)
Intersection Operations Analysis
The analysis of peak hour intersection Level of Service (LOS) is the primary indicator of circulation
system performance. For the analysis of the study area intersections, the City of Rosemead requires

that the Intersection Capacity Utilization (ICU) Method procedure be used.
ICU calculations used to determine the intersection volume-to-capacity ratio (V/C) and corresponding
LOS were based on the turning movements and intersection characteristics at the signalized
intersections. The methodology calculates the V/C ratio based on a default capacity [C] per lane, usually
1,600 vehicles per hour (vph) per lane and 2,280 vph for dual turn lanes. The total intersection loss
time of 10 seconds was applied to the V/C ratio.
The concept of intersection level of service is calculated as the volume of vehicles that pass through the
facility divided by the capacity of that facility. A facility is “at capacity” (v/c of 1.00 or greater) when
extreme congestion occurs. This volume/capacity ratio value is based upon volumes by lane, lane
capacity, and approach lane configurations.
Level of service (LOS) values range from LOS A to LOS F. LOS A indicates excellent operating
conditions with little delay to motorists, whereas LOS F represents congested conditions with excessive
vehicle delay. LOS E is typically defined as the operating “capacity” of a roadway. Significant traffic
impacts, the focus of this study, are defined using separate thresholds based on operational changes and
multiple level of service values.
Table 1 defines the Highway Capacity Manual3 LOS value ranges, based on volume/capacity ratio for
signalized intersections.
LOS E conditions denote near-capacity conditions, while LOS F conditions denote at-capacity or over-
capacity conditions.

Ratio
A
LOS A describes primarily free-flow operation. Vehicles are completely
unimpeded in their ability to maneuver within the traffic stream. Control delay
at the boundary intersections is minimal. The travel speed exceeds 85% of the
base free-flow speed.
0.00-0.60
B
LOS B describes reasonably unimpeded operation. The ability to maneuver
within the traffic stream is only slightly restricted and control delay at the
boundary intersections is not significant. The travel speed is between 67% and
85% of the base free-flow speed.
0.61-0.70
C
LOS C describes stable operation. The ability to maneuver and change lanes at
mid-segment locations may be more restricted than at LOS B. Longer queues at
the boundary intersections may contribute to lower travel speeds. The travel
speed is between 50% and 67% of the base free-flow speed.
0.71-0.80
D
LOS D indicates a less stable condition in which small increases in flow may
cause substantial increases in delay and decreases in travel speed. This
operation may be due to adverse signal progression, high volume, or
inappropriate signal timing at the boundary intersections. The travel speed is
between 40% and 50% of the base free-flow speed.
0.81-0.90
E
LOS E is characterized by unstable operation and significant delay. Such
operations may be due to some combination of adverse progression, high
volume, and inappropriate signal timing at the boundary intersections. The
travel speed is between 30% and 40% of the base free-flow speed.
0.91-1.00
F
LOS F is characterized by flow at extremely low speed. Congestion is likely
occurring at the boundary intersections, as indicated by high delay and
extensive queuing. The travel speed is 30% or less of the base free-flow speed.
Also, LOS F is assigned to the subject direction of travel if the through
movement at one or more boundary intersections has a volume-to-capacity
ratio greater than 1.0.

2. ANALYSIS
2.1. EXISTING ROADWAY CONDITIONS
This report section documents the existing traffic conditions and associated level of service (LOS) values
at the study intersections.
The analysis of operations at the study intersections was conducted for weekday a.m. and p.m. peak-
hour conditions. New traffic counts were conducted for this study in May 2014.
The results of the analysis of existing peak-hour intersection LOS are summarized in Table 4. The table
summarizes the analyzed weekday a.m. peak-hour and p.m. peak-hour conditions.
Table 4 – Study Intersection Performance
for Existing Peak-Hour Conditions
All the study intersections operate at good LOS values D or better under the existing conditions. At
the intersections of San Gabriel Boulevard/Garvey Avenue and Walnut Grove/Garvey Avenue, LOS D
conditions are approaching LOS E (near-capacity) conditions.
Figures 4 illustrate the lane configurations and intersection control utilized for the analysis of study
intersection capacities. Figures 5 illustrate intersection turning movement counts during the a.m. peak
hour, and Figures 6 illustrate the same for the p.m. peak hour.
The intersection turn movement traffic counts are provided in Appendix A to this report. Intersection
level of service analysis worksheets for the existing conditions scenario are provided in Appendix B.

INTRODUCTION
The purpose of this report is to determine the capacity of existing sewer reaches from
the proposed development project to the several Sanitation Trunk systems within the
City of Rosemead. The proposed development for this particular study is for the Garvey
Avenue Specific Plan. Garvey Avenue is well known for the City of Rosemead’s main
commercial corridor. The limits for the Specific Plan are between New Avenue and
Charlotte Avenue.
PROJECT DESCRIPTION
The City of Rosemead is proposing to enhance Garvey Avenue with new
Commercial/residential developments and provide a vibrant corridor with clean
storefronts and visible pedestrian friendly activities. The area of this Sewer Study is
between New and Charlotte Avenues.
The area between New Avenue and Del Mar Avenue is mostly designated as
Commercial. A commercial Supermarket is proposed as well as an existing vacant
property. The vacant property is designated commercial for future potential
development. An existing school is within this area and designated as Public Facilities.
The area between Del Mar Avenue and San Gabriel Boulevard is mostly designated
Commercial. However, there is one area that is designated as Regional Commercial
and will provide services in a large retail form to smaller local retailers. This area is
known as the Former Auto Auction. One (1) Mixed Use development is proposed at this
time and located at the north-east corner of Del Mar and Garvey Avenues. Another
potential Mix Use development is at 8002-8026 Garvey Avenue. The Sunny Chen
Property is also a potential development and has been designated as Commercial.
The area between San Gabriel Boulevard and Charlotte Avenue is currently designated
commercial.
SEWER CAPACITY ANALYSIS
Existing sewer pipes within the study have been analyzed from the proposed
development areas. The majority of the existing pipes are 8 inch diameter with varied
slopes along the flow path which then connects to downstream sewer trunk
connections. This particular study has five (5) sewer trunk connections.
The study areas between New and Del Mar Avenues have been analyzed from
contributing sewer flows of the existing conditions and proposed sewer flows from the
Garvey Avenue Specific Plan. There are two (2) existing 8” sewer lines on both sides of
1
the avenue within this area that account for discharge flows which is then collected
downstream to a 36” trunk sewer. Based on the proposed Garvey Avenue Specific Plan
Developments, sewers downstream will have inadequate capacities and will have to be
upsized.
The study area between Del Mar Avenue and San Gabriel Boulevard have been
analyzed in the same manner. Likewise, there are two (2) existing 8” sewers on both
sides of the avenue that are collected and discharged downstream to a 27” trunk sewer.
The sewers within this area have adequate capacities. However, should future plan
multi-story high density developments with such as hotels, multi-family residential
housing or multi-family mixed use buildings are proposed, each project will be assessed
individually for sewers capacities and impact.
The remaining study areas between San Gabriel Boulevard and Charlotte Avenue area
have been analyzed and are tributary to 8” sewer lines along San Gabriel Boulevard
and Garvey Avenue and discharged downstream to 21” trunk sewer. The areas to the
north and south of Garvey Avenue have adequate capacities to the 8” sewer line along
Garvey Avenue. However, the 8” sewer line along San Gabriel Boulevard between
Garvey Avenue and Park Street have inadequate capacities and will have to be
upsized.
Currently, the some of the existing sewers within the study areas show deficiencies in
capacity. This has been identified in the sewer area report prepared in 1996 for the City
of Rosemead and particularly located along Del Mar Avenue between Garvey Avenue
and Emerson.
In addition, a sewer system management plan was prepared in 2009 for the City of
Rosemead. An extensive analysis was made of the city’s entire sanitary collection
system and a rating system was developed for maintenance and structural defects of all
the sewer pipe segments. Defects requiring immediate attention are particularly located
along Garvey Avenue between Brighton and Strathmore Avenues.
SEWER DESIGN ANALYSIS
Based on the L.A. County Department of Public Works Land Development Division’s
Sewer Area Study requirements, the existing sewer pipe reaches are flowing at
maximum pipe capacity when they are all flowing 1 half-full for pipes with diameters
smaller than 15 inches. The as-built sewer plans (see Appendix B) were used to
determine the slopes and pipe sizes for the study area and are listed in sewer area
study tables and map herein (see Appendix E). L.A. County Sewer Index Maps are also
included for reference (see Appendix A).
The anticipated sewer discharge flow rates were calculated for various sewer line
reaches from Kutter’s Formula with “n=0.013” by using the Flow Master Computer
programs.
2
The discharged flow rates (Q) were calculated by using the Zoning Method. “Land Use”
of the properties within and around the study limits were defined by the City of
Rosemead’s Zoning Map and the Garvey Specific Plan Tour Map. The Zoning
Coefficients used here are the current L.A. County’s sewer area study flow coefficients.
For the potential developments with no data, flows were based on the zoning map and
zoning coefficients for ultimate build-out. For the known proposed development sites,
production flows were generated based on building square footage and dwelling units.
The following productions sites are as follows:
1) 7419-7459 Garvey Ave – Hawaiian Supermarket (Commercial Development)
48,000 sf of commercial bldg
48,000 sf x (100 gpd/1000 sf) = 4,800 gpd = 0.0074 cfs x 2.5 = 0.0185 cfs
2) 7801 Garvey Ave – Garvey Del Mar Mixed Use (Mixed Use Development)
33,956 sf of commercial bldg
33,956 sf x (100 gpd/1000 sf) = 3,395.6 gpd = 0.0052 cfs x 2.5 = 0.0131 cfs
45 units (4 floors)
45 units x 250 gpd/unit = 11,250 gpd = 0.0174 cfs x 2.5 = 0.0435 cfs
TOTAL = 0.0567 cfs
3) 8002-8026 Garvey Ave – Potential Site (Mixed Use Development)
15,553 sf of commercial bldg.
15,553 sf x (100 gpd/1000 sf) = 1,555.3 gpd = 0.0024 cfs x 2.5 = 0.0060 cfs
60 units (4 floors)
42 (1-bd room) units x 200 gpd/unit = 8,400 gpd
18 (2-bd room) units x 250 gpd/unit = 4,500 gpd
=12,900 gpd = 0.0199 cfs x 2.5 = 0.0498 cfs
TOTAL = 0.0558 cfs

CONCLUSION
Based on the sewer capacity analysis and hydraulic calculations, some of the existing
sewer pipes from the Garvey Avenue Corridor study area do exceed capacity. These
pipes have been impacted due to the development sites along the Garvey Avenue
Corridor and will need to be upgraded to larger pipe. The pipes in particular are the
reaches along Del Mar Boulevard to the 36” trunk connection at Emerson for the Study
Area between New & Del Mar Avenues and the reaches along San Gabriel Boulevard
to the 21” trunk connection for the Study Area at San Gabriel Boulevard & Garvey
Avenue. However, should the potential development sites intensify in land use zoning
density, further analysis will have to be accounted for.
