A RESOLUTION OF THE CITY COUNCIL OF THE CITY OF AZUSA APPROVING THE
CONSTRUCTION OF A NEW ROOF-TOP HELIPAD TO BE LOCATED ON A PROPOSED
BUILDING AT 1303 W. OPTICAL DRIVE, AZUSA, CALIFORNIA, 91702 THROUGH THE
APPROVAL OF UP-2020-03, DR-2020-06, AND MODIFICATION TO UP-2019-01, AND
FINDING THE PROJECT TO BE EXEMPT FROM THE CALIFORNIA
ENVIRONMENTAL QUALITY ACT (CEQA)
ANALYSIS:
Project Description
The Applicant is proposing to occupy an existing three-story office building of approximately 94,000
square feet, a new 30,769 square foot building addition consisting of offices, cafeteria, gym, and
conference/convention facility use with a helipad and parking structure. The use will operate 24 hours a
day and will be located at 1303 W. Optical Drive (the "Property") for the purpose of recovering,
processing, and distributing organs and tissues, including corneas, from deceased donors for transplant
(the “Project”).
Organ and tissue recovery is a process that requires personnel to operate on a 24 hour basis, so
OneLegacy will have three working shifts totaling about 250 people. The organ and tissue recovery will
all be conducted on-site and within the existing enclosed office building and will not include any type of
cremation processes or euthanasia.
The existing building would be utilized for laboratory services, organ and tissue processing, a 24-hour
donor triage and allocation, and supporting administrative offices. The proposed addition would support
the laboratory and office uses by also having a cafeteria and gym. The conference/convention facility
use will support training and events that uphold to the daily operations of the business functions. The
addition will also have a roof-top helipad that will be utilized to transport vital organs that require
immediate transportation.
The Property is a desirable location for Applicant’s Transplant Recovery Center because of the
industrial zoning and the site’s proximity to freeway access and to the greater Los Angeles area. This
site's location will serve to consolidate the Applicant's facilities now located in Downtown Los Angeles
and Placentia.
Project Analysis
Site Characteristics
The Property consists of 4.40 acres located on two parcels (APNs 8615-001-402 and 8615-001-064) at
1303 Optical Drive. The Property is developed with one three-story office building totaling
approximately 94,000 sf.
The property’s two parcels were merged with a Lot Line Adjustment (LLA-2006-02) in 2006. The two
parcels still remain since they are in different taxing areas as required by the Los Angeles County
Assessor’s Office.

Traffic, Access and Parking
The bodies of recently deceased organ and tissue donors will be brought to the Transplant Recovery
Center via ambulances, vans and helicopter and, after the organ and tissue recovery process, will be
transported to the appropriate mortuary. Surgical personnel would arrive at the facility by automobile 90
percent of the time and 10 percent of the time by helicopter at the proposed helipad on the rooftop or at a
regional airport and then to the property by car. Routine traffic will be limited to 250 scheduled staff,
spread over three shifts. Occasional traffic will include donor families and transplant recipient
volunteers who come to participate in training sessions.
The property is easily accessible to vehicles by Optical Drive, which connects to Irwindale Avenue to
the west, which in turn connects to I-210 to the north. The Project is also located immediately south of
and adjacent to the Irwindale Metro Gold Line Station. The station is approximately 1,200 feet to west at
the intersection of Irwindale Avenue and Optical Drive, which is within walking distance of the
property.

Economic Development
The proposed use will be one of the first medical laboratory uses in the area. If it succeeds, it may lead
to other medical uses being established in the City. The proposed use will bring medical practitioners to
the City for training sessions and conferences. These visitors will generate an economic benefit through
sales taxes and transient occupancy tax when they eat, stay, and play within the City’s boundaries. The
proposed use is expected to move over 250 jobs to Azusa from other cities in Los Angeles and Orange
Counties.
With this Project, the Applicant will relocate to the City from its current Downtown Los Angeles and
Placentia locations. One of the reasons the Applicant cited in its decision to relocate to the City was
because it recognizes that its employees travel from the Inland Empire and the San Gabriel Valley. The
City provides a central location for the Applicant’s employees with convenient access to freeways and
public transportation, including the Metro Gold Line.

Environmental Review
ENVIRONMENTAL DETERMINATION: Categorical Exemption
The proposed project is exempt from environmental review pursuant to the California Environmental
Quality Act (Pub. Resources Code, §§ 21000 et seq.) (“CEQA”) and the State CEQA Guidelines (Cal.
Code Regs, tit. 14, §§ 15000 et seq.). Specifically, the proposed project qualifies for the Class 32
Categorical Exemption (State CEQA Guidelines, § 15332), which applies to infill development projects
that meet specified conditions, as discussed below.
The project described herein is consistent with the Class 32 Categorical Exemption in that:
(a) The project is consistent with the applicable general plan designation and all applicable general
plan policies as well as with applicable zoning designation and regulations.
The project is located within the West End Industrial District. The proposed laboratory use is a
permitted use in the West End Industrial District. The Azusa General Plan land use designation for the
site is Industrial. The 4.40-acre site is currently developed with a three-story office building of
approximately 94,000 square. The proposed laboratory use is consistent with the uses allowed by the
existing zoning. In addition, refer to the General Plan Conformance sections in this staff report. Thus,
the project is consistent with the land use allowed for the site by the Azusa General Plan and
Development Code, as well as all applicable policies and regulations.
(b) The proposed development occurs within city limits on a project site of no more than five acres
substantially surrounded by urban uses.
The project site is located within the Azusa city limits and on a project site that is less than five acres
(4.40 acres). The site is surrounded by urban uses, including the Metro Right-of-Way to the North and
industrial uses to the south, west, and east. Optical Drive is located to the south of the property. Thus,
the project occurs on a site less than five acres and is substantially surrounded by urban development.
(c) The project site has no value for habitat for endangered species, rare, or threatened species.
The already developed office building has no environmental effects related to biological resources
associated with the existing office building. The addition will be constructed on already developed
property. Therefore the site of the proposed project, is not located near any vacant land with natural
vegetation supportive of sensitive species. Species located in the area would be limited to common
terrestrial species (such as squirrels) and birds that are commonly found in urban environments. Also, no
riparian habitat, other sensitive natural community, or wetlands area exists within the specific plan area,
the project site, or in the surrounding vicinity. And no wildlife corridors, native wildlife nursery sites, or
bodies of water in which fish are present are located in the specific plan area or in the adjacent areas.
(d) Approval of the project would not result in any significant effects relating to traffic, noise, air
quality, or water quality.

Traffic
On September 27, 2013, Governor Jerry Brown signed SB 743 into law, which initiated a process to
change transportation impact analyses completed in support of California Environmental Quality Act
(CEQA) documentation. SB 743 eliminates vehicular level of service (LOS) as a basis for determining
significant transportation impacts under CEQA and provides a new performance metric, vehicle miles
traveled (VMT). As a result, the State is shifting from measuring a project’s impact to drivers (LOS) to
measuring the impact of driving (VMT) as it relates to achieving State goals of reducing greenhouse gas
(GHG) emissions, encouraging infill development, and improving public health through active
transportation. To help lead agencies with SB 743 implementation, the Governor’s Office of Planning
and Research (OPR) produced a Technical Advisory and the City of Azusa City Council adopted the
City’s VMT approach on June 15, 2020.
The project is applicable to Screening VMT Criteria 1: Transit Priority Areas (TPA) Screening. The
project is located within ½ mile radius the Irwindale Station of Metro L Line (Gold Line). Attached is a
Vehicle Miles Traveled Screening Analysis which provides additional details = and explains all three
screening criteria.
In accordance with the Office and Planning and Research guidance for screening out projects from VMT
assessment, the Project can be screened out by application of the TPA Screening Criteria with the
presumption that the Project would have a less-than-significant impact to VMT.
Site access will be provided by three two-way drives alongOptical Drive. The driveway design is
adequate to provide suitable ingress/egress for both driveways. All on-site drive aisles are a minimum of
24-feet in width and adequate to provide internal circulation throughout the site, including access for
emergency vehicles, including police and fire department emergency equipment.
Noise
The proposed project will not have any additional noise impacts than the previous land use. The
previous land use operated between 7 AM to 9 PM as allowed by Azusa Municipal Code. The proposed
use will operate 24 hours, seven days a week. Azusa Municipal Code Noise Standards are the same for
all outdoor activity at day and night. The proposed project will also have a Condition of Approval that
will prohibit the use of sirens between 9 PM to 7 AM within the West End Industrial District of the
project area. Attached is a Noise Study that analyzed noise levels generated by helicopters within
standards of existing environment and estimate future noise levels surrounding land uses resulting from
operation of the project. The Noise Study found:
• Exterior noise levels from the three (3) proposed flight paths would not result in noticeable
changes of above 3 dBA at noise sensitive uses.
• Hourly noise levels from the three (3) proposed flight paths would not exceed the impulsive
noise threshold of 65 dB during the daytime (7:00 AM to 10:00 PM) and 60 dB during the
nighttime (10:00 PM to 7:00 PM) periods.

Air Quality
The short- and long-term project air emissions will not exceed any air emission thresholds established
by SCAQMD. Thus, the project will not have any significant air quality impacts.
Water Quality
The project must comply with Azusa Municipal Code Chapter 60 (Stormwater and Urban Runoff
Pollution Prevention), which specifies regulations regarding the discharge of stormwater (including
runoff) into the storm drain system within the City. The proposed project will occupy an existing built
office building.
In conclusion, operational-related runoff will not violate any water quality standards or waste discharge
requirements and/or otherwise substantially degrade water quality. Thus, the project will not have any
significant water quality impacts.
(e) The site is adequately served by all required utilities and public services.
The project can be served by all required utilities including electricity, natural gas, sewer, water, and
storm drains that exist on-site or Optical Drive. Also, public services, including police and fire
protection and trash collection will be provided to the project, as conditioned, ensuring adequate service
to the project.
CEQA Guidelines Section 15300.2 Exceptions, list five exceptions for the use of the Class 32
Categorical Exemption. As discussed below, none of these exceptions are applicable to the proposed
project.
(a) Cumulative Impact. All exemptions for these classes are inapplicable when the cumulative
impact of successive projects of the same type in the same place, over time is significant.
This exception applies when there is a potential for similar projects to occur in the same location as the
proposed project, over time, resulting in additional cumulative impacts. Successive projects will not
occur on the proposed project site, because the proposed project is occupying an existing commercial
building, and additional commercial buildings are not proposed on the same site. There are no projects
in Azusa that, along with the project, will have cumulative impacts. The infill exemption analysis above
considers all cumulative projects in the immediate vicinity of the site and concludes that there will not
be any significant cumulative impacts.
(b) Significant Effect. A categorical exemption shall not be used for an activity where there is a
reasonable possibility that the activity will have a significant effect on the environment due to
unusual circumstances.
There is nothing inherently unusual about the project site, or the surrounding vicinity, that would make
normally insignificant impacts potentially significant. Thus, the project will not have significant effects
on the environment due to unusual circumstances.

Page 10 of 10
(c) Scenic Highways. A categorical exemption shall not be used for a project which may result in
damage to scenic resources, including but not limited to, trees, historic buildings, rock
outcroppings, or similar resources, within a highway officially designated as a state scenic
highway.
None of the roads adjacent to or in close proximity to the site, including Optical Drive, are designated a
State of California scenic highway. Thus, the project will not impact a state scenic highway or damage
scenic resources within a state scenic highway.
(d) Hazardous Waste Sites. A categorical exemption shall not be used for a project located on a site
which is included on any list compiled pursuant to Section 65962.5 of the Government Code.
The project site is not a listed hazardous waste site pursuant to Section 65962.5 of the Government
Code.
(e) Historical Resources. A categorical exemption shall not be used for a project which may cause a
substantial adverse change in the significance of a historical resource.
The project site is not identified as a City designated historic property. Thus, the project will not have
any historical resource impacts.
Based on the above analysis, the project meets and complies with the conditions in CEQA Guidelines
Section 15332 and will not have any significant environmental impacts.
FISCAL IMPACT:
The proposed recommendation does not have any fiscal impact on the General Fund. Once the
reimbursement agreement is executed and when the applicant makes a deposit with the City, all
associated consultant costs will be paid through the Azusa Reimbursement Agreement. The
Reimbursement Agreement Template was approved by City Council on June 3, 2019.

ONELEGACY HELISTOP STUDY
FOR
CITY OF AZUSA
PREPARED BY
HELIPORT CONSULTANTS
FOR
OneLegacy
221 South Figueroa St. Suite 500
Los Angeles, CA 90012
PURPOSE: A rooftop helistop to support emergency medical
organ, eye, and tissue transplant procedures
servicing the population in seven counties in the
greater Los Angeles area.
HELISTOP NAME:OneLegacy Helistop
SITE LOCATION:1303 Optical Drive
Azusa, CA
HOURS OF OPERATION:24 hours/ 7 days a week
TYPE OF HELICOPTER:Representative Helicopter Models:
Weight range from 5,000 to 12,000 lbs
Sikorsky S76, AS 355, Agusta 109E
OneLegacy Helistop Study Heliport Consultants
City of Azusa, August 2020
PAGE 1
Attachment 3
1.0 REQUEST
OneLegacy, the applicant, is requesting approval for a private use rooftop
helistop to be used for the transportation of medical surgical teams for organ,
tissue and eye recovery where time is of the essence. OneLegacy serves an
area as far north as Santa Barbara and south to Riverside and San Bernardino
counties. The deceased donors will be transported to the OneLegacy facility by
ground ambulance. The medical teams may come from the recipient hospital by
helicopter to the Azusa OneLegacy facility, remove the donated organ from the
deceased donor, and then return to the recipient site with the recovered organ.
2.0 HELICOPTER TYPES
The helicopter emergency provider transports the medical teams and organs in
three different helicopter models (Figure 1: OneLegacy Helicopters) . The largest
model is the Sikorsky S76 (11,700 lbs) which is used when the medical recovery
team brings along a special heart/lung machine. The other two helicopters are in
the weight range of 5,000 to 7,000 lbs. All of the aircraft have twin turbine
engines.
3.0 BUILDING, HELIPAD, AND PROPERTY DESCRIPTION
3.1 Property Description
The site is located adjacent to the west Azusa boundary line (see Figure
2, Site Identification). The helipad will be located in a DW zone (West End
Industrial See Figure 3 Azusa Zoning Overlay). The 4.4 acres of property
is generally level in elevation and is trapezoidal shape with the north and
south property lines being parallel. The building is currently separated
from the surrounding streets by on-site surface parking to the west, north
and east. Landscaping to the south along W. Optical Drive provides
separation from the street.
3.2 Building/Helipad Description
The existing building (originally 94,000 sf) will be remodeled and
expanded to include a 3 story addition attached to its east side, with the
helipad on the roof. Connected to this addition will be a new 4 level
parking structure located to the east and below the elevation of the
helipad. The parking structure will replace some surface parking.
However, there will be an increase in total available vehicle parking
(Figure 4,5,6, and 7, Helipad Views).
This rooftop landing site is a “helistop” and not a “heliport”. There will be
OneLegacy Helistop Study Heliport Consultants
City of Azusa, August 2020
PAGE 2
no fueling, helicopter repairs, or overnight parking as could be provided at
a heliport. A good comparison would be to a bus stop versus a bus station
where a bus could be repaired or refueled. The helistop is solely for pick
up and delivery.
The helipad will be located 51 ft. above ground (627.38 ft. above mean
sea level) on a three story addition to the existing building. Thus, the
helipad will be high above the trees, landscaping, cars, trains and other
objects which might otherwise become obstacles in the flight path (Figure
8, Sector Approach).
A rooftop helipad is also more secure and safer than a ground level pad
since access to the helipad can be controlled and only authorized people
allowed entrance. .
4.0 RELATED APPROVALS
4.1 City of Azusa Use Permit No. UP-2019-01, Resolution No. 2019-PC07 for
24 Hour Operation and Finding the Project to be exempt from the
California Environmental Quality Act.
4.2 Federal Aviation Administration (FAA) - application for review of navigable
airspace in the area of the proposed helistop.
4.3 Airport Land Use Commission (ALUC) - application for regional review of
helistop by the Los Angeles Airport Land Use Commission regarding
issues of noise and safety.
4.4 Caltrans Division of Aeronautics (DOA) - application for a permit to
operate a private use helistop. The DOA is the responsible agency that
reviews and approves the helistop design and collects the approvals from
the other federal, regional, and local government agencies.
5.0 MAJOR DESIGN FEATURES OF THIS ROOFTOP HELISTOP
5.1 The State Division of Aeronautics is the agency that has jurisdiction over the
design compliance of the helistop using, as their design guide, the FAA Heliport
Design Advisory Circular 150/5390-2C (2012).
The rooftop helistop will be at an elevation of 51 ft. above ground (AGL). The
takeoff and landing area (load bearing area) is 53 x 53 ft. (See Figure 7)
The state and the federal government have jurisdiction over the helistop design.
This helipad will be designed to comply with the California Aeronautics
OneLegacy Helistop Study Heliport Consultants
City of Azusa, August 2020
PAGE 3
regulations (CCR, Title 21, Sections 3525 through 3560, 1997) and FAA AC-2C
(2012). Surrounding the helipad is a clear, obstruction free sector area as
shown in Figure 8.
The rooftop helipad site will be secure and only authorized helicopter pilots will
be permitted to land and use this facility. Since it is a private use facility, prior
landing permission is required.
5.2 Lights and Windcone on the Helipad
Eight (8) helipad LED green flush inset perimeter lights will be installed around
the perimeter of the takeoff and landing 53 ft dia. circle. Four (4) small but
efficient low level flood lights will be installed on 4 corners of the helipad. The
flood lights will be used to assist the pilot in identifying the landing site and to
help the medical team maneuver on the helipad.
A 10 ft high lighted orange windcone will be located on top of the elevator tower.
The windcone will have a red obstruction light on top and will be internally lit with
a LED light inside.
5.3 Fire Protection
Two 80-BC fire extinguishers as specified by the fire marshal and two wet stand
pipes will be located on the roofdeck near the helipad access stairs.
6.0 APPROACH/DEPARTURE FLIGHT PATHS AND NOISE EXPOSURE
6.1 Approach/departure Flight Paths
The flight paths are shown in Figure 9 with a zone overlay. The placement of the
helipad, the wind direction, the location of the noise sensitive areas and
ultimately the pilot’s opinion have all influenced the selection of the flight paths.
The helicopter takes off and lands into the wind similar to a fixed wing airplane.
The predominant wind direction is from the west/southwest. However, during the
Santa Ana wind conditions, the wind comes from the northeast. The helipad will
be located such that there will be clear, unobstructed airspace for approximately
270 degrees around the helipad (See Figure 8). This clear airspace will allow
the pilot to navigate in multiple directions depending upon the wind.
As seen in Figure 10 (Recipient Hospitals), the helicopter could be coming from
the west with medical teams from UCLA, Cedars Sinai, USC, or Children’s
Hospital. Or, it could be arriving from the east - Loma Linda Medical Center, and
Riverside Community Hospital. The area served to the south of Azusa may
include flights from UCI and St. Joseph Hospital of Orange
The pilots try to fly over major streets or highways, and industrial areas. In this
case, the new OneLegacy facility is located in an industrial zone surrounded by
manufacturers, and to the south is a sand quarry. Farther to the west is the

PAGE 4
Santa Fe Dam Recreational Area. The use of the three flight paths will allow the
pilot to vary the approach or departures depending upon the desired direction of
travel, avoidance of repetitive overflights, and the wind conditions.
The main approach from the west will be over the I-210 freeway at approximately
1000 ft above ground. A little past the intersection of I-605 and the I-210 over
the Santa Fe Dam Recreation Area, the flight path will turn north to E. Foothill
Blvd. The pilot will follow this easterly route until turning south just before W.
Virginia Ave., and then west along the Metro tracks on approach into the
westerly wind to land at the helipad. The departure would be along Flight Path 2
or 3.
During Santa Ana wind conditions the pilot will approach from the west and
execute the same flight path except turn onto Flight Path 2 or 3 to land into the
northeast wind at the helipad.
Coming from the hospitals to the south or the east, the pilots will approach over
the quarry, or, if approaching from the east they will stay north of the Metro
tracks to stay over the industrial area.
6.2 Noise Abatement Procedures to Reduce Noise Exposure
The pilots at all times will use noise abatement flight procedures often referred to
as “Fly Neighborly” (Helicopter Association International (HAI)). The flight
procedures were developed by helicopter manufacturers to be consistent with
the aircraft’s capabilities and safety of flight.
In order to reduce noise exposure on the ground, the pilot will typically approach
and depart the helistop at a steeper slope than normal, approximately a 5 to 1
horizontal to vertical approach path ( or a 11 deg. angle ) (see Fig. 11). Of
course, this depends upon the aircraft’s capabilities. This approach/departure
slope profile (see Fig.12) will reduce the noise exposure on the ground by as
much as 80% and is considered an acceptable noise abatement procedure.
Figure 12 illustrates how a normal approach results in a larger noise footprint on
the ground whereas a little steeper angle of approach will significantly reduce the
noise level.
7.0 PILOTING TECHNIQUES
7.1 Suggested Piloting Noise Abatement Procedures
Follow the generally recommended manufacturer’s procedures for “Flying
Neighborly”. Use these noise abatement procedures along with taking into
consideration the safety aspects in executing any helicopter flight operations.
C Maintain maximum distance and altitude separation from noise sensitive
areas such as residential, and recreational areas.

C Use ingress and egress routes to the helipad that follow the flight paths
over the major highways and streets.
C Fly normal cruising speed
C Observe low-noise speed and descent recommendations
C Avoid sharp maneuvers
C Vary the approach and departure routes
CONCLUSION
The OneLegacy helistop is strategically located in an industrial area, near railroad tracks and a
busy interstate freeway. The helicopter operations at the proposed helistop are compatible with
the existing noise levels in the area. The flight paths and the piloting techniques are factors that
can be taken into consideration to minimize any adverse impact on the community.

EXECUTIVE SUMMARY
This Noise Report is intended to provide the City of Azusa (City) with environmental impact report
information needed to maintain noise levels generated by helicopters to within established standards. This
Noise Report describes the existing environment in the Project area and estimate future noise levels at
surrounding land uses resulting from operation of the Project. The study discusses applicable federal,
State, and local noise regulations; monitoring data; applicable noise thresholds; the methodology used to
analyze potential noise impacts; and the modeled on-site uses. The finding of the analyses are as follows:
•Exterior noise levels from the three (3) proposed flight paths would not result in noticeable
changes of above 3 dBA at noise sensitive uses.
•Hourly noise levels from the three (3) proposed flight paths would not exceed the impulsive
noise threshold of 65 dB during the daytime (7:00 AM to 10:00 PM) and 60 dB during the
nighttime (10:00 PM to 7:00 PM) periods.
•The results determine the proposed helistop will comply with all applicable governmental
noise standards.
INTRODUCTION
The Applicant is proposing to occupy an existing three-story office building of approximately 97,000 square
feet located at 1303 W. Optical Drive (refer to Figure 1: Regional and Project Site Location) for the purpose
of recovering, processing, and distributing organs and tissues, including corneas, from deceased donors
for transplant. The Project site consists of 4.4 acres located on two parcels (APNs 8615-001-042 and 8615-
001-064). The Project is surrounded by industrial uses, with access provided by Optical Drive, which
connects to Irwindale Avenue to the west. Additionally, the I-210 freeway and the Irwindale Metro Gold
Line Station is located immediately adjacent to the north.
The Proposed Project includes the remodel and expansion of the three-story office building from 97,000
square feet to 127,620 square feet in addition to construction of a new parking structure on the vacant
parking lot located to the east. The new use includes office space, clinical space for organ, tissue and eye
recovery and preparation for transplantation to recipients at other facilities. Ancillary uses include a
convention center, a cafeteria for employees and convention center users, a gym, warehouse areas
and landscaped areas. The proposed helipad would be located on the roof of the new addition.
Pilots would be instructed to use the specified approach/departure path (“flight paths”), as illustrated in
Figure 2: Flight Path, unless conditions (e.g., strong winds, temporary obstructions, obscured view, etc.)
favor alternate approaches/departures. All flights would approach the Project Site from the west, as
medical teams would be arriving to the facility from USC, Cedars, or UCLA. Additionally, all flights would
OneLegacy Helipad Project 2 City of Azusa
Noise Study July 2020
be departing to the west/southwest given the predominant wind conditions. As shown in Figure 2, all
three (3) flight paths would follow the I-210 freeway corridor and would not operate directly over
residential uses.
The rooftop helistop would be approximately 52 feet above ground level. It is anticipated the most
common type of helicopters that would utilize the helistop would include the Agusta A-109, Aerospatiale
AS-355F Twin Star (AS-355), and the Sikorsky S-76. The maximum takeoff weight would range between
approximately 5,000 and 12,000 pounds. Based on historical data of a similar use, it is anticipated that 90
percent of flights would occur during the daytime period (7:00 AM–7:00 PM), 5 percent of flights would
occur during the evening period (7:00 PM–10:00 PM), and 5 percent of flights would occur during the
nighttime period (10:00 PM–7:00 AM). It is anticipated that 70 percent of flights would be from the Agusta
A-109, 25 percent from the AS-355, and 5 percent from the Sikorsky S-76.
DEFINITION OF NOISE
Loudness, measured in decibels (dB), is the most commonly used characteristic to describe noise. The A-
weighted decibel (dBA) is used in aircraft noise analyses because it incorporates a frequency-dependent
rating scale that more closely associates sounds and sound frequencies with the sensitivity of the human
ear. Some common sounds on the dBA scale, relative to ordinary conversation, are provided in Table 1:
Common Sounds on the A-Weighted Decibel Scale. As shown in Table 1, the relative perceived loudness
of sound doubles for each increase of 10 dBA, although a 10 dBA change corresponds to a factor of 10 in
relative sound energy. Generally, sounds with differences of 2 dBA or less are not perceived to be
noticeably different by most listeners. A noise event produced by a helicopter flyover is usually
characterized by a build up to a maximum noise levels as the helicopter approaches, and then a decrease
in the noise level through a series of lesser peaks or pulses after the aircraft passes and the noise recedes.

NOISE STANDARDS
Federal
The Federal Noise Control Act of 1972 establishes programs and guidelines to identify and address the
effects of noise on public health and welfare and the environment. The US Environmental Protection
Agency (USEPA) administrators determined in 1981 that subjective issues such as noise would be better
addressed at more local levels of government. Consequently, in 1982 responsibilities for regulating noise
control policies were transferred to state and local governments. However, noise-control guidelines and
regulations contained in the rulings of the USEPA in prior years remain in place, enforced by designated
federal agencies where relevant.
State
The State of California, Office of Planning and Research has published, with regard to community noise
exposure, recommended guidelines for land use compatibility. These guidelines rate land use compatibility
in terms of being normally acceptable, normally unacceptable, and clearly unacceptable. Each jurisdiction
is required to consider these guidelines when developing a general plan noise element and when
determining acceptable noise levels within its community. These guidelines are representative of various
land uses that include residential, commercial/mixed-use, industrial, and public facilities. Figure 3: Land
Use Compatibility to Noise, identifies the acceptable limit of noise exposure for various land use
categories within the County. Noise exposure for single-family uses is normally acceptable when the CNEL
at exterior residential locations is equal to or below 60 dBA; conditionally acceptable when the CNEL is
between 55 to 70 dBA; and normally unacceptable when the CNEL exceeds 70 dBA. These guidelines apply
to noise sources such as vehicular traffic, aircraft, and rail movements.
The California Noise Insulation Standards 1 require that interior noise levels from exterior sources be 45
dBA or less in any habitable room of a multiresidential-use facility (e.g., hotels, motels, dormitories, long-
term care facilities, and apartment houses, except detached single-family dwellings) with doors and
windows closed. Measurements are based on CNEL or Ldn (the day–night average), whichever is consistent
with the noise element of the local general plan. Where exterior noise levels exceed 60 dBA CNEL, an
acoustical analysis for new development may be required to show that the proposed construction would
reduce interior noise levels to 45 dBA CNEL. If the interior 45 dBA CNEL limit can be achieved only with
the windows closed, the residence must include mechanical ventilation that meets applicable Uniform
Building Code (UBC) requirements.
1 California Code of Regulations, Title 24, sec. 3501 et seq.
NORMALLY ACCEPTABLE
Specified land use is satisfactory, based upon the assumption that any buildings involved are of normal conventional construction,without any special noise insulation requirements.
CONDITIONALLY ACCEPTABLE
New construction or development should be undertaken only after a detailed analysis of the noise reduction requirements is madeand needed noise insulation features included in the design. Conventional construction, but with closed windows and fresh air supplysystems or air conditioning will normally suffice.
NORMALLY UNACCEPTABLE
New construction or development should generally be discouraged. If new construction or development does proceed, a detailedanalysis of the noise reduction requirements must be made and needed noise reduction features included in the design.
CLEARLY UNACCEPTABLE
New construction or development should generally not be undertaken.

The City’s Noise Ordinance establishes exterior and interior noise limits that cannot be exceeded at
neighboring properties due to noise generated on private property. Standards are defined for four noise
zones based on the impacted property’s use:
• Noise Zone I: includes all residential properties
• Noise Zone II: includes all professional office and public institutional properties
• Noise Zone III: includes all commercial properties with the exception of professional office properties;
and
• Noise Zone IV: includes all industrial properties.
Table 2: Exterior Noise Standards and Table 3: Interior Noise Standards provides the City’s exterior and

METHODOLOGY
Noise Modeling
Noise-level calculations at the location of noise-sensitive land uses in the Project vicinity were assessed
using the SoundPLAN noise model. The SoundPLAN model depicts noise contours at varying distances and
accounts for various inputs to analyze topography, vegetation, propagation from buildings, and existing-
and proposed-noise sources and barriers. The SoundPLAN model takes into account the varying slant
distances between the helicopter and the receiver. The software uses various inputs to analyze the
topography, vegetation, vehicle traffic, existing- and proposed-noise sources, and existing- and proposed-
barriers to depict noise contours at varying distances. The software utilizes algorithms (based on the
inverse square law) to calculate noise level projections. Accuracy has been validated in published studies
to be +/- 2.7 dBA with an 85 percent confidence level. The software allows the user to input specific noise
sources, spectral content, sound barriers, building placement, topography, and sensitive receptor
locations. Helicopter flight profiles were modeled based on the flight paths shown in Figure 2 above and
were programmed into the SoundPLAN noise modeling system.
Existing Noise Environment
The area surrounding the Project site is highly urbanized with industrial uses and multiple noise sources
including, but not limited to the I-210 freeway and the Irwindale Metro Gold Line Station adjacent to the
north and industrial activities from the Cemex Azusa Quarry to the south.
Noise measurements were taken with a Larson Davis Type 1 meter. This meter meets the American
National Standards Institute standard for general environmental noise measurement instrumentation.
Random incidence microphones with windscreens were used, given the outdoor (i.e., free field) conditions
of monitoring. The sound level averages were measured as A-weighted, slow-time-weighted (1-minute
period) sound pressure level variables, commonly used for measuring environmental sounds. Sound levels
presented in this report are in terms of dBA.
To quantify the existing noise environment, short-term (15-minute) measurements were taken at four (4)
locations during both the daytime period (7:00 AM to 10:00 PM) and the nighttime period (10:00 PM to
7:00 AM) and shown in Figure 4: Ambient Noise Monitoring Locations.
Results of the short-term ambient noise measurements are presented in Table 6: Short-term (15-minute)
Ambient Noise Measurements. As shown in Table 3, short-term measurements during the daytime period
(7:00 AM to 10:00 PM) ranged from a low of 46.6 dBA on the corner of Zamara Street and Parkside Avenue
(Site 2) to a high of 65.5 dBA on the corner N. Virginia Avenue and W. 6th Street (Site 2). Additionally, short-
term measurements during the nighttime period (10:00 PM to 7:00 AM) ranged from a low of 51.4 dBA

on the corner of Zamara Street and Parkside Avenue (Site 2) to a high of 65.6 dBA on the corner N. Virginia

THRESHOLD OF SIGNIFICANCE
For determination of significant noise impacts in a given environment, noise levels changes brought about
by a specific project are often evaluated in the context of preexisting noise conditions in that environment
and the type of land use affected. For quieter, existing noise environments, as opposed to already noisy
environments, long-term project-induced noise level changes are allowed to be higher before the project
causes a significant impact. Noise level changes most frequently utilized for determination of significance
of long-term impacts at noise-sensitive locations range from 10 dBA for quiet rural areas, to 3 dBA to 5
dBA for urban areas with noisier settings, and occasionally 1.5 dBA for locations exposed to higher noise
levels, such as homes within the 65 dBA Ldn contour of an airport. For residential land uses, changes in
noise levels are often evaluated in terms of 24-hour average noise metrics (i.e., CNEL, or Ldn). Thresholds
similar to these are already adopted by federal agencies (such as Federal Transit Administration and
Federal Aviation Administration), and state and local jurisdictions.
Although the City has not specifically adopted such thresholds, CEQA requires that a noise study
adequately assess noise level increases caused by a project for determination of its impacts on the
environment.
Although the term “substantial increase” is not explicitly defined by CEQA, a reasonable threshold can be
formulated based on an increase required to be audible by most individuals. The human ear can detect
changes in sound levels of approximately 3 dBA under normal, controlled conditions. A change of 5 dBA
is noticeable to most people in an exterior environment. Changes of between 1 to 3 dBA may be noticeable
under quiet background conditions.
More specifically, if project-related increase in noise levels results in overall noise levels exceeding the
goal of the General Plan for the land use (i.e., 65 dBA CNEL for residential land uses), the project would
cause a significant impact. Also, based on human perception of changes in noise levels, an increase of 3
dBA in CNEL or more could be deemed to constitute a “significant increase.” Similarly, under peak-hour
traffic conditions, a 3 dBA increase in hourly Leq may be used as a threshold of significance. The thresholds
of significance outlined in this section would apply to frequently-used exterior areas of noise-sensitive
land uses where increase in noise would directly affect people.
IMPACT ANALYSIS
For the helicopter approach, once a ground speed of 0 is reached, the helicopter begins vertical descent
to the landing pad, which takes approximately 15 seconds. Once on the helipad surface, the helicopter
undergoes a 30-second ground idle. Following the idle period, the helicopter is shut down. Overall, the
entire duration of the helicopter approach takes under 2 minutes.
OneLegacy Helipad Project 17 City of Azusa
Noise Study July 2020
For the helicopter departure, start-up and flight checks are performed during the ground-idle phase, which
typically lasts up to 3 minutes. Following the flight checks and start-up, the rotor blades begin turning at
full power, hover is initiated, and the aircraft ascends vertically above the pad, which lasts approximately
15 seconds. Once desired altitude is reached, the helicopter accelerates horizontally and departs the
Project site. Overall, the main noise-producing portion of the departure to altitude and cruising speed
from initial start-up takes under 1 minute, with surrounding land uses exposed to maximum sound levels
for less than 15 seconds during this period.
Based on previous data provided by Helinet regarding flight operations, historically a maximum of three
(3) flights have taken place from a single facility between the daytime hours of 7:00 AM to 10:00 PM on
any given day and a maximum of two (2) flights have taken place from a single facility between the
nighttime hours of 10:00 PM to 7:00 AM on any other given day. Therefore, to simulate worst-case scenario
helicopter approach/departure impacts, it was assumed six (6) events (3 approach and 3 departure) would
take place during the daytime period and four (4) events (2 approach and 2 departure) would take place
during the nighttime period on the same day.
Helicopters are designated with maximum takeoff weight (MTOW) classes. The Agusta A-109 and AS-355
fall within the same weight class, as the Agusta A-109 has a MTOW of approximately 2,850 kilograms
(6,283 pounds) and the AS-355 has a MTOW of approximately 2,600 kilograms (5,732 pounds).
Additionally, the Sikorsky S-76 has a MTOW of approximately 5,306 kilograms (11,700 pounds) which falls
into a different weight class.
All flights for helicopters would be limited to the approach/departure patterns illustrated in Figure 2 unless
occasional variations are needed due to unfavorable wind conditions. As mentioned previously, all flights
would approach the Project Site from the west and depart to the west/southwest given the predominant
wind conditions.
Flight Path 1
As shown in Figure 2, the helicopter approach to the pad begins with the aircraft traveling at 1,000 feet
above ground level (AGL) along the I-210 Freeway. The helicopter would traverse along Foothill Boulevard
and turn south just before N. Virginia Avenue, then turn west on the railroad tracks and begin descent to
500 feet AGL at approximately 1,000 feet from the pad. Additionally, at approximately 500 feet from the
pad, the helicopter would descend to 250 feet AGL and slow to a 50 feet hover above the pad. As
mentioned above, once a ground speed of 0 is reached, the helicopter would begin vertical descent to the
landing pad.
OneLegacy Helipad Project 18 City of Azusa
Noise Study July 2020
As shown in Table 7: Exterior Noise Levels – Flight Path 1, the Agusta 109 and AS-355 helicopter would
increase daytime noise levels by a maximum of 0.2 dBA at the residential neighborhood at Zamara Street
and Parkside Avenue (Site 2). Additionally, nighttime noise levels would increase by a maximum of 0.2 dBA
at the residential neighborhood along W. 4th Street and Zachary Padilla Avenue (Site 1) and Site 2.
Furthermore, the Sikorsky S-76 would increase exterior noise levels during the daytime and nighttime by
a maximum of 0.7 dBA and 0.6 dBA at Site 2, respectively. As such, noise levels would not result in
noticeable changes of above 3 dBA at noise sensitive uses and impacts would not be significant.
Given the temporary duration of a helicopter flight event, exterior noise levels were also compared to the
impulsive noise thresholds near residential areas described in Table 5 above. As shown in Table 8: Exterior
Noise Levels (Hourly) – Flight Path 1, hourly noise levels would not exceed the impulsive noise threshold
of 65 dB during the daytime and 60 dB during the nighttime. As such, impacts at the noise-sensitive uses
would not be significant.
The hourly results of the predictive modeling process for each helicopter type are shown graphically in
Figure 5: Flight Path 1 Contour Map (Agusta 109 & AS-355) and Figure 6: Flight Path 1 Contour Map
(Sikorsky S-76).

Flight Path 2
As shown in Figure 2 for the south-westbound departure, the pilot would use the best rate-of climb (BROC)
speed based on site conditions and would climb wide to 500 feet AGL at distance of 500 feet from the pad
and continue to climb to 1,000 feet AGL before reaching Irwindale Avenue. The helicopter would
accelerate to cruise speed along the I-210 westbound freeway. Additionally, if site conditions allow, the
aircraft would be higher than 1,000 feet AGL at Irwindale Avenue.
As shown in Table 9: Exterior Noise Levels – Flight Path 2, the Agusta 109 and AS-355 helicopters would
increase daytime noise levels by a maximum of 0.4 dBA at the residential neighborhood at Zamara Street
and Parkside Avenue (Site 2). Additionally, nighttime noise levels would increase by a maximum of 0.3 dBA
at the residential neighborhood at Site 2. Furthermore, the Sikorsky S-76 would increase exterior noise
levels during the daytime and nighttime by a maximum of 1.0 dBA and 0.8 dBA at Site 2, respectively. As
such, noise levels would not result in noticeable changes of above 3 dBA at noise sensitive uses and
impacts would not be significant.
Given the temporary duration of a helicopter flight event, exterior noise levels were also compared to the
impulsive noise thresholds near residential areas described in Table 5 above. As shown in Table 10:

As shown in Figure 2 for the southbound departure along Aerojet Avenue, the pilot would use the BROC
speed based on site conditions to be at a minimum of 500 feet AGL before reaching the Cemex Azusa
Quarry. The aircraft would continue to climb right to 1,000 feet AGL crossing across Irwindale Avenue and
accelerate to cruise speed along I-210 Freeway westbound.
As shown in Table 11: Exterior Noise Levels – Flight Path 3, the Agusta 109 and AS-355 helicopters would

Technical Memorandum
Date: August 21, 2020
To: Manuel Muñoz, Planning Division, City of Azusa
From: Jeremy Klop, Miguel Núñez, and Dongyang Lin, Fehr & Peers
Subject: Azusa OneLegacy Project Vehicle Miles Traveled Screening Analysis
LA20-3217
This memorandum documents the assessment of vehicle miles traveled (VMT) for the proposed
expansion of an existing office building located at 1303 West Optical Drive in the City of Azusa,
California per the relevant State and City requirements. The assessment finds that the project is
presumed to have a less-than-significant impact to VMT.
Project Information
The site was previously occupied and operated as an office; however, that use has not been active
since March 2015. The site would be occupied by OneLegacy, a federally designated organ
procurement organization serving the greater Los Angeles area. The proposed OneLegacy project
(Project) intends to remodel and expand the existing building to include additional office and
laboratory space, conference/convention facility, parking, and a helipad for medical team
transportation.
Regulatory Context
On September 27, 2013, Governor Jerry Brown signed SB 743 into law, which initiated a process to
change transportation impact analyses completed in support of California Environmental Quality
Act (CEQA) documentation. SB 743 eliminates the vehicular level of service (LOS) as a basis for
determining significant transportation impacts under CEQA and provides a new performance
metric, vehicle miles traveled (VMT). As a result, the State is shifting from measuring a project’s
impact to drivers (LOS) to measuring the impact of driving (VMT) as it relates to achieving State
goals of reducing greenhouse gas (GHG) emissions, encouraging infill development, and improving
public health through active transportation. To help lead agencies with SB 743 implementation, the
Governor’s Office of Planning and Research (OPR) produced a Technical Advisory1 and the City of
Azusa City Council adopted the City’s VMT approach on June 15, 2020. The following sections

describe relevant VMT considerations for evaluating and assessing transportation impacts for the
proposed Project and the potential for significant impacts to the environment per CEQA.
VMT Screening
OPR’s Technical Advisory suggests three screening criteria that agencies may use to identify if a
proposed project is presumed to cause a less-than-significant VMT impact: project accessibility to
transit, project size, and project location in a low VMT area. If a project meets any one of three
screening criteria, then no further VMT assessment is required. These screening criteria are relevant
for the City of Azusa (the City) when conducting the VMT assessment for the proposed Project.
Screening Criteria 1: Transit Priority Areas (TPA) Screening - Applicable
Projects located in a Transit Priority Area (TPA) or along a High-Quality Transit Corridor (HQTC) may
be screened out from further VMT analysis because they are presumed to have a less than
significant impact absent substantial evidence to the contrary. TPAs are defined in the OPR
Technical Advisory as a ½-mile radius around an existing or planned major transit stop or an existing
stop along a HQTC. A HQTC is defined as a corridor with fixed route bus or rail transit service
frequency of 15 minutes (or less) during peak commute hours.
The Project is located within the boundary of an existing TPA, less than ½ mile from the Irwindale
Station of Metro L Line (Gold Line) (Figure 1). Los Angeles Metro operates the L Line rail service on
a scheduled 8-minute frequency in both the AM and PM peak periods during weekdays2. While a
modified schedule related to temporary COVID-19 operation conditions may vary from previously
scheduled operations, no planning or programming documents have shown plans for changes to
the L Line that would reduce frequency beyond the 15-minute threshold.
While the Project meets the basic transit frequency and proximity criteria, the Technical Advisory
notes conditions that may still require additional analysis. The presumption that a project in a TPA
will have a less than significant impact absent substantial evidence to the contrary may not be
appropriate if the project:
1.Has a Floor Area Ratio (FAR) of less than 0.75;
2.Includes more parking for use by residents, customers, or employees of the project than
required by the jurisdiction (if the jurisdiction requires the project to supply parking);
3.Is inconsistent with the applicable Sustainable Communities Strategy (as determined by
the lead agency, with input from the Metropolitan Planning Organization); or
4.Replaces affordable residential units with a smaller number of moderate- or high-income
residential units.

The Project is proposed to have a Floor Area Raito of 0.95 (Table 1), which is more than 0.75. Thus,
the TPA Screening criteria is appropriate for the Project.
Pursuant to the City’s Code of Ordinance, the Project is required to provide 332 parking spaces.
Table 2 presents the land use breakdown and applicable parking ratios to determine the number
of spaces required. The Project proposes to include 351 parking spaces. Table 3 presents the
breakdown of parking spaces to be provided at the proposed Project. There are two reasons for
providing slightly more parking spaces. First, the proposed development provides a
conference/convention facility that will primarily be used by existing employees of the site. Events
would be sporadic and would typically not generate employment VMT associated with this land
use and would be able to allow for some visitors, if there are any. Additionally, the parking code
requirements are being applied to uses with unique characteristics for on-site restaurants,
conference/convention facility, and office. Since these are primarily intended for internal use and
the office is proposed for laboratory use - that does not include medical offices or visiting patients
– the additional parking spaces are provided to meet code parking requirements and avoid the
potential for parking spillover. As such, it is intended to serve the on-site uses and would not be
anticipated to serve additional activity at the site that would generate additional employment VMT.
Additionally, the employer would offer an incentive for the use of public transportation. The
proposed Project would result in the building entry being closer to the nearby transit stop than
OneLegacy’s current office entry.
The Project is consistent with Southern California Association of Governments (SCAG) 2020-2045
Regional Transportation Plan/Sustainable Communities Strategy, in which the Project site is
designated as General Industrial in SCAG’s General Plan land use. The Project continues to be
located in a Transit Priority Area according to SCAG’s 2045 Plan3.
There are no affordable residential units in the existing building, so the Project would not replace
any affordable residential units. Thus, the TPA Screening criteria is applicable to the Project.

Screening Criteria 2: Project Size – Not Applicable
OPR guidance identifies local serving project types that may be presumed to have a less than
significant impact absent substantial evidence to the contrary. These include uses such as resident
and/or employee serving uses like retail, daycare facilities, parks, gas stations, and the like. This
screening criteria also allows for projects generating fewer than 110 daily trips to be screened out.
For office or industrial facilities, projects generating less than 110 daily vehicle trips4 typically
corresponds with the following:
•3,000 sq. ft. of medical-dental office building5
•11,000 sq. ft. of general office building5
•22,000 sq. ft. of general light industry5
•10,000 sq. ft. of research and development center5
The proposed project consists of 115,828 square feet of office and laboratory, and therefore the
Project Size criterion does not apply for screening.
Screening Criteria 3: Low VMT Area Screening – Not Applicable
OPR guidance states that residential and office projects located within a low VMT generating area
may be presumed to have a less than significant impact absent substantial evidence to the contrary.
A low VMT generating area generally has higher density, a mix of land uses, and provides
opportunities for people to walk to nearby uses instead of always driving. Low VMT areas are
defined as areas that are currently generating VMT below the VMT threshold6. As defined by the
City of Azusa, a Low VMT TAZ for employment is a location where the VMT per employee is 15
percent or more below the Baseline VMT defined as the SGVCOG Northeast Subarea VMT. The
traffic analysis zones (TAZs) contained in the SCAG model can be used to identify the low VMT
areas in the City of Azusa.
4 This threshold ties directly to the OPR technical advisory and notes that CEQA provides a categorical
exemption for existing facilities, including additions to existing structures of up to 10,000 square feet, so
long as the project is in an area where public infrastructure is available to allow for maximum planned
development and the project is not in an environmentally sensitive area. (CEQA Guidelines, § 15301, subd.
(e)(2).) Typical project types for which trip generation increases relatively linearly with building footprint (i.e.,
general office building, single tenant office building, office park, and business park) generate or attract an
additional 110-124 trips per 10,000 square feet. Therefore, absent substantial evidence otherwise, it is
reasonable to conclude that the addition of 110 or fewer trips could be considered not to lead to a significant
impact.
5 Threshold may be higher depending on the tenant and the use of the site. This number was estimated using
rates from ITE’s Trip Generation Manual (10th Edition).

For the City of Azusa, Low VMT areas for employment generate no more than 18.69 VMT per
employee. The project is not located in a low VMT TAZ. Therefore, this criterion does not apply for
screening.

Project Screening Results – Less than Significant
In accordance with the OPR guidance for screening out projects from VMT assessment, the Project
can be screened out by application of the TPA Screening Criteria with the presumption that the
Project would have a less-than-significant impact to VMT.
