IV. Environmental Impact Analysis
D. Light, Glare, and Shading
1. Introduction
This section addresses the potential impacts that could result from the proposed
Project with regard to light, glare, and shading.
a. Light and Glare
Artificial light impacts are typically associated with light that occurs during the
evening and nighttime hours, and may include streetlights, illuminated signage, vehicle
headlights, and other point sources. There are two types of artificial, or man-made, light
sources: (1) point sources (e.g., illuminated signage, street light poles, vehicle headlights);
and (2) indirect sources that reflect light onto adjacent properties (e.g., reflective or lightcolored surfaces). The effect produced by indirect light sources is commonly referred to as
“glare.” Point sources are addressed in the analysis of nighttime illumination impacts, while
indirect sources are addressed in the analysis of glare impacts.
Nighttime illumination of varying intensities is characteristic of most urban and
suburban land uses, including those in the City of Pasadena (City). New nighttime light
sources have the potential to increase ambient nighttime illumination levels and result in
spillover of light onto adjacent properties. These effects have the potential to interfere with
certain functions including vision, sleep, privacy, and general enjoyment of the natural
nighttime condition. The significance of the impact depends on the type of use affected,
proximity to the affected use, the intensity of the light source, and the existing ambient light
environment. Typically, land uses that are considered sensitive to nighttime light include,
but are not limited to, residential, some commercial and institutional uses, and natural
areas. These land uses are recognized as light-sensitive because they are typically
occupied by persons who have expectations for privacy during evening hours and who are
subject to disturbance by bright light sources (or in the case of natural areas, biological
resources that are subject to disturbance by bright light sources). The analysis below
evaluates the potential for the nighttime lighting sources introduced by the Project to impact
these light-sensitive uses.
Glare is primarily a daytime occurrence caused by the reflection of sunlight or
artificial light from highly polished surfaces, such as highly reflective window glass or other

materials, and, to a lesser degree, from broad expanses of light-colored surfaces. Daytime
glare generation is common in urban areas and is typically associated with mid- to high-rise
buildings with exterior façades largely or entirely comprised of highly reflective glass or
mirror-like materials from which the sun can reflect, particularly following sunrise and prior
to sunset. Glare generation is typically related to sun angles, although glare resulting from
reflected sunlight can occur regularly at certain times of the year. Glare can also be
produced during evening and nighttime hours by artificial light directed toward a lightsensitive land use. The analysis of glare provided below assesses the Project’s potential
impacts on glare-sensitive uses, which include light-sensitive uses and transportation
corridors (i.e., roadways).
b. Shading
Shading from buildings and structures has the potential to block direct sunlight onto
nearby land uses that are sensitive to the effects of shading. Although shading is a
common and expected quality in urban areas, and considered a beneficial feature of the
environment when it provides cover from excess sunlight and heat, it can have an adverse
impact if the blockage interferes with sun-related activities and desired sunlight at shadesensitive uses. Shadow effects depend on several factors, including the local topography,
height and bulk of a project’s structural elements, sensitivity of adjacent land uses, season,
and duration of shadow projection. Typically shade-sensitive uses include all residential
uses and routinely usable outdoor spaces associated with recreational or institutional uses
(e.g., schools, convalescent homes); commercial uses such as pedestrian-oriented outdoor
spaces or restaurants with outdoor dining areas; nurseries; and existing solar collectors.
These uses are considered sensitive because sunlight is important to function, physical
comfort, or commerce.
For the purposes of this analysis, the two solstices (i.e., summer and winter) and two
equinoxes (i.e., spring and fall) are analyzed to describe the variety of conditions that occur
during the course of the year.
(1) Winter and Summer Solstice
“Solstice” is defined as either of the two points on the ecliptic (i.e., the path of the
earth around the sun) that lie midway between the equinoxes (separated from them by an
angular distance of 90 degrees). At the solstices, the sun’s apparent position on the
celestial sphere reaches its greatest distance above or below the celestial equator, about
23.5 degrees of the arc. At winter solstice, about December 21, the sun is overhead at
noon at the Tropic of Capricorn; this marks the beginning of winter in the Northern
Hemisphere. At the time of the summer solstice, about June 21, the sun is directly
overhead at noon at the Tropic of Cancer. In the Northern Hemisphere, the longest day

and shortest night of the year occur on this date, marking the beginning of summer.
Measuring shadow lengths for the winter and summer solstices represents the extremes of
the shadow patterns that occur throughout the year. Shadows cast on the summer solstice
are the shortest shadows during the year, becoming progressively longer until the winter
solstice when the shadows are the longest during the year. Sunset during the winter
solstice occurs at approximately 4:48 P.M., while sunset during the summer solstice occurs
at approximately 8:08 P.M.
(2) Fall and Spring Equinox
At the time of the fall equinox, near September 21, and the spring equinox, near
March 21, night and day are nearly the same length and the sun crosses the celestial
equator moving southward (in the northern hemisphere). The fall equinox marks the first
day of the season of fall and the spring equinox marks the first day of the season of spring.
During the autumn and spring equinoxes, sunset occurs at approximately 7:05 P.M.
2. Environmental Setting
a. Regulatory Framework
(1) Light and Glare
(a) Pasadena Municipal Code
Lighting, such as streetlights and illuminated signs, is regulated by the Pasadena
Municipal Code (“PMC”). Applicable regulations for the Project Site include the following:

Section 17.40.080 regulates glare and outdoor lighting. Specifically, all lighting
shall be energy-efficient, and shielded or recessed so that direct glare and
reflections are confined to the maximum extent feasible within the boundaries of
the site, and shall be directed downward or onto specific doors and entryways of
buildings for security purposes and away from surrounding properties and public
rights-of-way.
No lights shall blink, flash, or be of high intensity or brightness. No permanently
installed lighting shall blink, flash, or be of unusually high intensity or brightness,
as determined by the Zoning Administrator.
Lighting shall be appropriate in scale, intensity, and height. All lighting fixtures
shall be appropriate in scale, intensity, and height to the use they are serving.

Section 17.48.100, General Provisions for On-Premise Signs, regulates the
appearance and lighting of commercial signs, requiring, among other provisions,
that the artificial illumination of signs, either from an internal or external source,

be designed to eliminate negative impacts on surrounding rights-of-way and
properties.

Section 17.48.110.D, Neon Signs and Architectural Lighting, limits the use of
lighting for architectural accent.

Section 17.61.030, requires new lighting fixtures, as well as exterior finish,
colors, and materials to be closely evaluated through the design review process,
which further ensures that project lighting would be sensitive to, and compatible
with the surrounding community. This regulatory procedure provides the City with
an opportunity to incorporate additional conditions to improve the project building
materials and lighting fixtures.
(b) Central District Specific Plan
The Project is located within the Central District, which is subject to the guidelines
set forth in the Central District Specific Plan (CDSP). The CDSP is a resource which
contains standards and guidelines used by the City to implement the goals and policies of
the General Plan. The CDSP contains standards and guidelines pertaining to light and
glare in pedestrian areas, parking garages, and on building façades. The proposed Project
would be subject to the following CDSP guidelines:

Guideline SE 6.1, Include Pedestrian-Scaled Lights, Incorporate pedestrian
scaled fixtures that emit a warm light along streets and sidewalks; sidewalks
should be well-lit.

Guideline SE 6.2, Include Pedestrian-Scaled Lights, Direct lighting along
sidewalks and pedestrian walks to produce minimal glare.

Guideline SP 4.7, Create Comfortable Outdoor Rooms, Design outdoor space
with safety in mind; on-site public plazas should promote visibility from the street,
and provide architecturally compatible lighting to enhance nighttime security.

Guideline SP 6.6, Control Vehicular Access and Parking, Direct parking lot
lighting away from adjacent properties, and use pedestrian-scaled fixtures that
emit a warm light.

Guideline BD 9.3, Require Compatible Parking Structures, Provide architectural
screens and/or a rhythm of window-like punched openings arranged so as to
articulate the façade, hide parked vehicles, and shield lighting.

Guideline UR 5.5, Compose Attractive Residential Façades, Use clear or lightly
tinted window glazing, and discourage the use of simulated muntins in favor of
structural muntins (i.e. true-divided lights); exceptions may be considered
provided they are architecturally integrated and support a high-quality design.
Reference the Design Guidelines for Windows in Multi-unit Residential Projects
found in the Citywide Design Principles & Criteria.

There are no regulations concerning shading at the local, regional, or Statewide
levels.
b. Existing Light and Glare Environment
The Project Site is in a highly urbanized area located adjacent to the Old Pasadena
Historic District, immediately south of Interstate 210 (I-210), three blocks west of City Hall,
and three blocks north of the commercial uses on Colorado Boulevard. Existing nighttime
light sources within the area surrounding the Project Site consist of pole-mounted
streetlights for visibility and safety purposes, parking lighting, illuminated building signs,
light spillage from buildings, architectural lighting on building façades and in landscaped
areas, and lighting from vehicle headlights and traffic. Typical of this urban context,
existing ambient lighting levels in the Project vicinity are considered medium to high.
Existing nighttime lighting sources within the Project Site include interior lighting
from the existing structures, low-level security lighting fixtures that illuminate the surface
parking areas, exterior lighting on building façades, including the “Parsons” sign near the
top of the 12-story tower located in the North Development Area, and lighting from vehicle
headlights. The on-site light sources generally result in low to medium ambient nighttime
light levels within the Project Site, depending on the time of night and the number of
vehicles utilizing the parking lot.
Daytime glare is generally associated with reflected sunlight from buildings with
highly reflective surfaces. Activities that would be sensitive to daytime glare from reflected
sunlight include motorists traveling on the adjacent roadways and people working in
adjacent buildings. Glare in the Project vicinity is periodically generated by reflective
materials on the doors and windows of the surrounding commercial buildings and glare
from vehicles passing along the surrounding streets. The primary sources of glare
generated from within the Project Site are the windshields of moving and parked vehicles in
the surface parking lots. Depending on the angle of the sun, the glass doors and glass
windows from the existing on-site buildings also produce daytime glare. Minimal lighting is
produced by the above-ground parking garages south of Holly Street.
In the immediate vicinity of the Project Site, the nearest off-site receptor that could
be considered sensitive relative to artificial or nighttime light and glare is the Marriott
Courtyard Hotel on Fair Oaks Avenue, east of the Project Site. The Marriott Courtyard
Hotel has a direct view of the Project Site. In addition, St. Andrew Church and Memorial
Park were also initially considered as analysis locations, but due to their distance from the
Project Site and the presence of intervening existing development, it was determined that

further analysis of these two locations would not be required as these two locations would
not be adversely affected by artificial light and glare conditions occurring at the Project Site.
As mentioned above, the Project Site is located adjacent to the Old Pasadena
Historic District and near the Pasadena Civic Center. The Old Pasadena Historic District
contains a number of historically designated buildings and is also a commercial center that
contains mixed-use, infill development, and pedestrian-friendly streetscapes that define the
area. Typically, illumination in this area is comprised of pedestrian scaled fixtures that emit
a warm light along the streets and sidewalks. While not considered a sensitive receptor,
development surrounding the Historic District should be cognizant of the uses and ambient
lighting found within the District.
c. Existing Shadow Environment
The Project Site is split into two areas: the North Development Area, north of Holly
Street, and the South Area, south of Holly Street. The North Development Area is currently
developed with a 12-story office building (193 feet) and three 4-story pods that connect to
the 12-story tower. These buildings are surrounded by surface parking lots. Given the
height of the 12-story tower, shadows on off-site uses are generated during certain times of
the year. In the winter, spring and fall, shadows are cast to the west on Pasadena Avenue
and the freeway right-of-way in the early morning, on the on-site pedestrian plaza and the
sidewalks of Walnut Street to the north, and on Fair Oaks Avenue and the land uses to the
east, including the Marriott Courtyard Hotel. Shadows from the 12-story tower are more
prominent on the land uses to the east during evenings in the spring and fall. Summer
shadows are less prominent and, since the buildings are surrounded by surface parking
lots, the majority of the shadows cast do not extend beyond the boundaries of the Project
Site.
The South Area is currently developed with two 8-story buildings that are 116 feet in
height, each with an above grade parking structure. Similar to the North Development Area,
the structures in the South Area cast shadows to the west on Pasadena Avenue in the
morning hours, to the north onto Holly Street and an on-site pedestrian walkway during the
afternoon, and to the east on Fair Oaks Avenue in the evenings of the winter, spring, and
fall seasons. Summer shadows are less prominent and generally do not extend beyond the
boundaries of the Project Site.
The surrounding land uses are typical of those found within a developed urban area.
Across Walnut Street to the north of the Project Site are a freestanding office building,
freestanding restaurant, surface parking lot, and vacant land, a portion of which has been
approved for a Marriott Residence Inn Hotel, with the balance being proposed for
residential use. The block to the northeast of the Project Site consists of commercial uses

on the southern portion of the block fronting Fair Oaks Avenue and Walnut Street and St.
Andrew School on the north portion of the block fronting Chestnut Street. To the east of
the Project Site across Fair Oaks Avenue are a gas station, Marriott Courtyard Hotel, and
various commercial uses. Memorial Park is located one block east of these uses on
Raymond Avenue, between Walnut Street and Holly Street. The block to the southeast of
the Project Site consists of various commercial uses. Interstate 210 and the freeway rightof-way are located immediately west of the Project Site across Pasadena Avenue.
As identified in Figure IV.D-1 on page IV.D-8, shade-sensitive uses in the area of
potential impact that are considered in this analysis include:

Sensitive Receptor 1: The St. Andrew School located on the block northeast of
the Project Site at the corner of Fair Oaks Avenue and Chestnut Street. This
receptor includes two paved recreation areas;

Sensitive Receptor 2: The Marriott Courtyard Hotel pool and courtyard located
midblock along Fair Oaks Avenue between Walnut Street and Holly Street
directly east of the Project Site. The pool and courtyard are located east of the
hotel structure; and

Sensitive Receptor 3: Memorial Park located approximately one-tenth of a mile
to the east of the Project Site on Raymond Avenue between Walnut Street and
Holly Street.
3. Environmental Impacts
a. Methodology
(1) Light and Glare
The analysis of light and glare identifies the location of light-sensitive land uses and
describes the existing ambient conditions on the Project Site and in the project vicinity.
The analysis describes the Project’s proposed light and glare sources, and the extent that
Project lighting, including illuminated signage, would spill off the Project Site onto adjacent
light-sensitive areas. The analysis also describes the affected street frontages, the
direction in which the light would be focused, and the extent to which the proposed Project
would illuminate sensitive land uses. The analysis also considers the potential for sunlight
to reflect off of building surfaces (glare) and the extent to which such glare would interfere
with the operation of motor vehicles or other activities.

(2) Shading
In determining the effects of shading, the locations of shadow-sensitive uses in the
surrounding area are identified in Figure IV.D-1 on page IV.D-8. The shadow model
assumes a maximum building height of 75 feet in the northern portion of the site
(Development Area B and northern portion of Development Area C) and 60 feet in the
southern portion of the site (Development Area A and the southern portion of Development
Area C), as illustrated in Figure III-6 in Section III, Project Description, of this Draft EIR.
The shadow model also assumes varying setbacks from zero to 10 feet, as shown in
Table III-4, in Section III, Project Description, of this Draft EIR.
While the threshold below uses a range of months, shadows are modeled and
plotted for representative hours during the winter solstice, summer solstice, fall equinox,
and spring equinox. Specifically, shadow lengths are plotted between 9:00 A.M. and
3:00 P.M. on the winter solstice and between the hours of 9:00 A.M. and 5:00 P.M. during the
summer solstice, spring equinox, and fall equinoxes. Shading patterns are modeled for
each hour during those periods.
The varying and seasonally adjusted daytime hours represent the period of the day
in which the expectation of available sunlight exists. For the purpose of establishing the
hours in which significant impacts occur, winter is described as occurring during Pacific
Standard Time, which occurs between the first Sunday of November through the second
Sunday in March; and spring, summer, and fall are described as occurring during Pacific
Daylight Time, which occurs between the second Sunday in March and the first Sunday of
November. Routinely useable outdoors spaces associated with residential, cultural,
recreational or institutional (e.g., schools, convalescent homes) uses, outdoor spaces and
areas of commercial uses, nurseries, as well as solar collectors and areas where sunlight
may be important to physical comfort or function, are considered shadow sensitive uses.
At this time, the proposed Project does not have a specific site plan. Instead, the
proposed Project is defined in terms of the development standards section forth in
Section III, Project Description, of this Draft EIR. These documents allow the Project Site
to be developed with flexibility according to future market conditions and other factors.
Included in the development standards are a set of height limits and building setbacks
where buildings can be located on the Project Site. In order to show the extent of every
shadow that could potentially be cast from the Proposed Project, the shadow analysis
assumes that all area available for building development on the Project Site is built to the
maximum height allowable. By doing so, the shadows shown in the analysis will be
applicable for any combination of development that is allowable by the City of Pasadena’s
Design Guidelines, Central District Specific Plan, and Citywide Zoning Code and the
proposed Project’s development standards.

b. Thresholds of Significance
(1) Light and Glare
The proposed Project may have a significant impact related to light and glare if it
would:

Create a new source of substantial light and glare which would adversely affect
day or nighttime views in the area.
(2) Shading
The proposed Project may have a significant impact on shadow-sensitive uses if it
would:

Shade shadow-sensitive uses would be shaded by project-related structures for
more than three hours between the hours of 9:00 A.M. and 3:00 P.M. Pacific
Standard Time (between early November and early March), or for more than four
hours between the hours of 9:00 A.M. and 5:00 P.M. Pacific Daylight Time
(between early March and early November).
As noted in the discussion of methodology, while the thresholds use a range of
months, the analyses presented below are provided during the equinoxes and solstices,
which represent the times of maximum potential impact during each of the four seasons of
the year.
c. Regulatory Compliance Measures and Project Design
Features
(1) Regulatory Compliance Measures
The proposed Project would comply with all applicable regulatory standards.
Implementation of the following Regulatory Compliance Measures, as currently required
and/or as may be amended in the future, are intended to reduce impacts related to lighting:

Regulatory Compliance Measure D-1: All lighting is required to be energyefficient, and shielded or recessed so that direct glare and reflections are
confined to the maximum extent feasible within the boundaries of the site, and
shall be directed downward or onto specific doors and entryways of buildings for
security purposes and away from surrounding properties and public rights-ofway.


Regulatory Compliance Measure D-5: The use of neon tubes for signs or
architectural elements are allowed in commercial zoning districts only as set forth
in PMC Section 17.48.110.D.

Regulatory Compliance Measure D-6: New lighting fixtures, as well as
exterior finish, colors, and materials will be closely evaluated through the design
review process, to further ensure that project lighting would be sensitive to, and
compatible with the surrounding community. This regulatory procedure provides
the City with an opportunity to incorporate additional conditions to improve the
project building materials and lighting fixtures.
be
(2) Project Design Features
The Project’s proposed design incorporates the following four types of lighting
sources that would be located within the Project Site: (1) site lighting; (2) building lighting;
(3) street lights; and (4) special lighting. Site lighting would be found throughout the Project
Site, particularly along the proposed paseos and would assist in wayfinding while also
addressing on-site safety and security. These light sources would be low intensity in
nature. Building lighting, which would also be low-intensity in nature, would be used for
building identification and to create building accents. Also included in this category of
lighting is lighting associated with the Project’s proposed signage which would be
characterized as having a low to medium intensity, with the light intensity of the signage
being regulated through the Project’s Master Sign Plan. The third category of on-site light
sources is street lights. The design for the Project’s street lights would reflect the style,
design, light quality, and color consistent with that which is currently found on the adjacent
streets. The Project’s plan for street lights also includes establishing continuity along Holly
Street and Leonard J. Pieroni Street to form a “T” pattern flowing into Holly Plaza, thereby
providing connections to Old Pasadena in a manner consistent with the Bennett Plan. The
last category of proposed light sources is special lighting. On-site areas where special
lighting would be used are limited to Holly Plaza and Leonard J. Pieroni Street.
Specifically, special thematic lighting may be incorporated into the design for Holly Plaza,
and this lighting while not extending beyond the Project Site, may be visible beyond the
Project boundaries along Holly Street and De Lacey Avenue. Along Leonard J. Pieroni
Street itself, special lighting consisting of low intensity thematic lighting in the form of light

strings across the street may occur as a means of enhancing the pedestrian experience
along this proposed pedestrian pathway connecting the Project Site to Old Pasadena.
The following Project Design Features are proposed with regard to light and glare:
Project Design Feature D-1: Light sources associated with Project construction
would be shielded and/or aimed so that no direct beam illumination is
provided outside of the Project Site boundary.
However,
construction lighting would not be so limited as to compromise the
safety of construction workers.
Project Design Feature D-2: Glass used in building façades would be antireflective or treated with an anti-reflective coating in order to
minimize glare.
Project Design Feature D-3: Outdoor lighting would be designed and installed
with shielding and directed towards the interior of the Project Site so
that the light source does not project directly upon any adjacent
property.
Project Design Feature D-4: The use of spotlights, flood lights, klieg lights, or
similar high intensity light source for outdoor lighting at the Project
Site would be prohibited.
d. Project Impacts
(1) Light and Glare Impacts
(a) Construction Impacts
Construction activities associated with Phase 1 and Phase 2 of the proposed Project
would involve the use of various lighting sources which have the potential to spillover to
off-site sensitive land uses in the Project vicinity. Sensitive land uses, such as the Marriott
Courtyard Hotel immediately to the east, could be exposed to potential light sources from
the Project Site. However, construction activities at the Project Site would be subject to the
provisions of the PMC Section 9.36.070, which limits the hours of construction to between
7:00 A.M. and 7:00 P.M. Monday through Friday and between 8:00 A.M. and 5:00 P.M. on
Saturday, with no construction permitted on Sundays. Accordingly, construction would
primarily occur during daylight hours and construction light sources would be used as
needed in the evening hours. Construction-related illumination during nighttime hours
would also be provided on the Project Site for safety and security purposes. However, this
lighting, as well as any other nighttime lighting that may be used during Project
construction, would be shielded and/or aimed so that no direct beam spills over outside of
the Project Site boundary, as described in Project Design Feature D-1, above. As such,

IV.D Light, Glare, and Shading
impacts to off-site sensitive uses from lighting sources associated with Phase 1 and
Phase 2 construction activities would be considered less than significant.
Daytime glare associated with Phase 1 and Phase 2 construction activities could
potentially occur if reflective construction materials were positioned in highly visible
locations where the reflection of sunlight could occur. However, it is unlikely that this would
occur given the fact that large, flat surfaces, like those needed to generate glare, are
typically not associated with construction activities. Moreover, any glare produced during
construction activities would be highly transitory and short-term, given the movement of
construction equipment and materials within the construction site and the temporary nature
of construction activities. The potential for nighttime glare is considered negligible given the
fact that construction would occur mainly during the daytime hours, as noted above, and
that lighting during the nighttime hours would be for safety and security purposes and, as
such, would be shielded and/or aimed so that no direct beam spills over outside of the
Project Site boundary. Furthermore, the proposed Project would implement Project Design
Feature D-1, above, which requires the shielding of construction related light sources.
Therefore, impacts to off-site sensitive uses from daytime and nighttime glare during
Phase 1 and Phase 2 would be considered less than significant.
As described above, construction-related impacts related to light and glare would not
significantly impact off-site sensitive uses. Nonetheless, the proposed Project would
implement Project Design Feature D-1, above, which would require construction related
light sources to be shielded and/or aimed so that no direct beam illumination is provided
outside of the Project Site boundary. As such, any potential impacts from light and glare
during Phase 1 and Phase 2 construction to off-site sensitive uses would be considered
less than significant.
(b) Operational Impacts
The northern portion of the Project Site is currently developed with a 12-story tower,
three 4-story pods that connect to the tower, and surface parking lots that surround the
structures. Development of the proposed Project would take place in the area that is
currently serving as the surface parking lots. The proposed Project would include the
development of commercial and residential uses, both of which would increase the number
of vehicle trips to and from the Project Site. Accordingly, the Project would increase the
light and glare levels emanating from the Project Site. New sources of artificial lighting that
would be introduced by the Project would include: site lighting along walkways and
landscaping, and safety and security lighting; interior and exterior building lighting and
signage lighting; street lighting; and special lighting along Holly Plaza, Holly Street, and
Leonard J. Pieroni Street. The Project would not include electronic signage or signs with
flashing, mechanical, or strobe lights. New sources of glare would include building
surfaces, such as glass doors or windows, and Project-related vehicles.

Site lighting would be found throughout the Project Site and would assist in
wayfinding, while also addressing on-site safety and security. Light sources within the
Project Site would include lighting along walkways, landscaped areas, and safety and
security lighting. Site lighting has the potential to spillover to off-site sensitive land uses in
the Project vicinity; however, lighting would be low intensity and directed towards the
interior of the Project Site to avoid light such spillover. In addition, Project lighting sources
would be similar to other lighting sources in the Project vicinity and would not generate
artificial light levels that are out of character with the surrounding area. Furthermore,
lighting on the Project Site would be subject to Regulatory Compliance Measures D-1 and
D-4, which regulate glare and outdoor lighting and requires evaluation of lighting sources
during design review of the Project, respectively, and Project Design Features D-1, D-3,
and D-4, which deal with the design of lighting sources on the Project Site. In addition,
Project development would also result in the removal of all lighting associated with the
existing on-site parking uses and the new lighting sources on the Project Site would be
integrated into a mixed-use environment that would implement the Regulatory Compliance
Measures and Project Design Features to create a lighting environment that complements
the existing conditions found in the surrounding area. Thus, compliance with these
measures would reduce any impacts from site lighting on off-site sensitive uses.
Building lighting would be used for building identification and to create building
accents. This would also include lighting associated with the Project’s proposed signage,
interior lighting visible through the windows of the residential units and the ground-floor
lobby, and interior lighting visible from commercial uses. In general, building lighting used
on the Project Site would be low intensity in nature and proposed signage would be
characterized as having a low to medium intensity, with the light intensity of the signage
being regulated through the Project’s Master Sign Plan. Furthermore, as noted above, the
proposed Project would not include electronic signage or signs with flashing, mechanical,
or strobe lights and would be required to comply with Regulatory Compliance Measures
D-1 through D-6, which regulate lighting for on-site buildings and signage, as well as
requiring the evaluation of on-site lighting sources during design review of Phase 1 and
Phase 2 development which would also be the means by which consistency with the
lighting design guidelines set forth in the City’s Central District Specific Plan would be
achieved. Lighting would also be required to implement Project Design Features D-1, D-3,
and D-4, which guide the design of light sources occurring within the Project Site.
Compliance with these measures would reduce any impacts associated with building
lighting, including signage, on off-site sensitive uses. Therefore, impacts from building and
signage lighting associated with Phase 1 and Phase 2 development as well as at Project
buildout would be less than significant.
The design for the Project’s street lights would reflect the style, design, light quality,
and color consistent with that which is currently found on the adjacent streets. The

IV.D Light, Glare, and Shading
Project’s plan for street lights would establish continuity along Holly Street and Leonard J.
Pieroni Street to form a “T” pattern flowing into Holly Plaza, thereby providing connections
to Old Pasadena. Additionally, the design of the street lights would be required to be
evaluated during design review of the Project, as specified by Regulatory Compliance
Measure D-4. As such, there would be less-than-significant impacts associated with the
Project’s street lighting that is installed in as part of Phase 1 and Phase 2 development.
On-site areas where special lighting would be used are limited to Holly Plaza and
Leonard J. Pieroni Street. As described above, special thematic lighting may be
incorporated into the design for Holly Plaza, and that this lighting while not extending
beyond the Project Site, may be visible beyond the Project boundaries along Holly Street
and De Lacey Avenue. Along Leonard J. Pieroni Street itself, special lighting consisting of
low intensity thematic lighting in the form of light strings across the street may occur as a
means of enhancing the pedestrian experience along this proposed pedestrian pathway
connecting the Project Site to Old Pasadena. As stated above, all proposed on-site lighting
would be subject to regulatory compliance measures and project design features as well as
being an important consideration during the City’s design review process for Phase 1 and
Phase 2 development during which Project consistency with the applicable lighting design
guidelines set forth in the City’s Central District Specific Plan would be confirmed.
Compliance with these measures would reduce any impacts associated with special
lighting in and around the Project Site. Therefore, special lighting associated with Phase 1
and Phase 2 development, as well as at Project buildout, would not result in significant
impacts to off-site sensitive uses.
As described above the Project would include new sources of glare, including
building surfaces and Project-related vehicles. The Project would be designed in a
contemporary architectural style and would feature various surface materials. At this time it
is not known the exact nature of the building materials that would be used for the proposed
Project; however, typical building materials include terra cotta, stucco, aluminum, glass,
tile, and metal. Of those materials, highly reflective glass and metal have the greatest
potential to generate glare by the reflection of sunlight or artificial light on these surfaces.
As such, the Project would use non-reflective glass or glass that has been treated with a
non-reflective coating in all exterior windows and building surfaces to reduce potential glare
from reflected sunlight. Additionally, any metal building surfaces used as a building material
would be used as accent materials, such as metal awnings and aluminum storefronts, and
would not cover expansive spaces. Furthermore, the selection of building materials for the
proposed Project would be subject to the Project Design Feature C.2-2, which requires the
use of non-reflective glass, and Regulatory Compliance Measure C.2-4, which would
require evaluation of building materials during the design review process. Adherence to
these measures would ensure that building materials would not have the potential to
produce a substantial degree of glare.

IV.D Light, Glare, and Shading
In addition to building materials, Project-related vehicles also have the potential to
produce glare when exposed to sun. Under existing conditions there are surface parking
lots which contain vehicles that have the potential to produce glare. However, parking
structures associated with the proposed Project would be subterranean, which would
eliminate the reflection potential from parked cars as viewed from surrounding areas and
roadways during the day and night, and would substantially reduce lighting levels from
vehicle headlights during the night.
Furthermore, it should be noted that the proposed Project is anticipated to include
landscaping throughout the Project Site. Certain types of landscaping, such as trees and
large shrubbery, would serve to limit on-site light sources and reduce potential glare from
reflected sunlight and from vehicle headlights during the night. Thus, impacts would be
reduced further with the installation of certain types of landscaping at the Project Site.
Based on the above, with the implementation of the Regulatory Compliance
Measures and Project Design Features, lighting and glare associated with Project
operation would not substantially alter the character of off-site areas surrounding the
Project Site. Therefore, impacts from Project-related sources of artificial light and glare
during Project operations during both Phase 1 and Phase 2 as well as at Project buildout
would be less than significant.
(2) Shading Impacts
As discussed in Chapter III, Project Description, of this Draft EIR, the Project Site
would be developed with 620,000 sf of office uses, 10,000 sf of restaurant uses, and
475 residential units in the North Development Area. Development of the proposed Project
would take place in the existing surface parking lots surrounding the 12-story Parsons
tower and pod buildings. As shown in Figure III-6 in Section III, Project Description, of this
Draft EIR, Development Area A and the southern part of Development Area C would be
constructed to a height of 60 feet or less. Additionally, Development Area B and the
northern portion of Development Area C would be constructed up to a height of 75 feet.
Building setbacks would vary, but would generally be zero to 10 feet, as shown in
Table III-4 in Section III, Project Description, of this Draft EIR.
Development of the proposed Project would generate new shading with varied
lengths and angles depending on the time of day and season. As discussed above, a
significant shading impact would occur if the Project would shade off-site shade-sensitive
uses for more than three hours between 9:00 A.M. and 3:00 P.M. Pacific Standard Time
(between early November and early March) or for more than four hours between 9:00 A.M.
and 5:00 P.M. Pacific Daylight Time (between early March and early November).

WORKING DRAFT – Not for Public Review
IV.D Light, Glare, and Shading
(a) Winter Solstice
Shading impacts are typically greatest during the winter months due to the sun’s low
position in the sky. As shown in Figure IV.D-2 and Figure IV.D-3 on pages IV.D-18 and
IV.D-19, Project shading during the winter would extend west across Pasadena Avenue in
the morning, northwest and north across Walnut Street from mid-morning to mid-afternoon,
and northeast and east across Fair Oaks Avenue in the late afternoon. Sidewalks and
landscaping adjacent to Pasadena Avenue, Walnut Street, and Fair Oaks would also be
shaded during this time. Land uses north of Walnut Street that would be shaded for the
majority of the day include: office uses; a restaurant; and a vacant parcel of land.
Additionally, an office building, gas station, and the Marriott Courtyard Hotel east of Fair
Oaks Avenue would be shaded from approximately 3:00 P.M. until sunset at approximately
4:48 P.M. It should be noted that only the southern portion of the properties on Walnut
Street and the eastern façades of the properties on Fair Oaks Avenue would be cast into
shadow and the courtyard and swimming pool portion of the hotel would not be shaded.
Furthermore, the land uses that would be shaded during this period are not classified as
shade-sensitive uses. Therefore, given that the proposed Project would not shade sensitive
uses for more than three hours during the winter solstice, impacts related to shading would
be considered less than significant.
(b) Spring Equinox
As shown in Figure IV.D-4 through Figure IV.D-6 on pages IV.D-20 through IV.D-22,
Project shadows during the spring equinox would extend west and north shading Pasadena
Avenue and the sidewalks along Walnut Street in the morning. Portions of the shadows
would extend past Pasadena Avenue onto the landscaped areas within the freeway rightof-way, which is not accessible to the public. Shading would continue to extend north to
shade the sidewalks and a portion of the pavement along Walnut Street throughout the
afternoon. By late afternoon the shadows would extend east across Fair Oaks Avenue,
with the greatest shading impacts around 5:00 P.M. The only land uses that would be
shaded are the uses east of Fair Oaks Avenue, after the hour of 3:00 P.M. As noted
above, these land uses include a gas station and the Marriott Courtyard Hotel. Sensitive
Receptor 2, the pool and courtyard to the east of the hotel structure, would be shaded
starting at 4:30 P.M. and covered entirely by 5:00 P.M. However, it should be noted that the
shading over Sensitive Receptor 2 is being cast by the existing 12-story structure as shown
in Figure IV.D-6. Thus, the pool area would be shaded even without development of the
proposed Project. Given the existing shadows, impacts to shade-sensitive uses from
development of the proposed Project during the spring equinox would be considered less
than significant.

IV.D Light, Glare, and Shading
(c) Summer Solstice
As illustrated in Figure IV.D-7 through Figure IV.D-9 on pages IV.D-24 through
IV.D-26, summer shadows from the Project Site would cause limited shading to the west on
Pasadena Avenue in the morning and on the façades of the land uses to the east of Fair
Oaks Avenue in the afternoon. Shading would occur after 5:00 P.M. on the land uses to the
east of Fair Oaks Avenue. As discussed a significant shading impact would occur if the
Project would shade off-site shadow-sensitive uses for more than four hours between the
hours of 9:00 A.M. and 5:00 P.M., between early March and Early November. Given that
shadow impacts would not occur until after 5:00 P.M. on the east side of Fair Oaks Avenue
and would not last more than four hours, shading generated by the proposed Project during
the summer solstice would be considered less than significant.
(d) Fall Equinox
Shading during the fall equinox is similar to the shading during the spring equinox.
As shown in Figure IV.D-10 through Figure IV.D-12, pages IV.D-27 through IV.D-29,
Project shading during the fall equinox would extend west and north shading Pasadena
Avenue and the sidewalks along Walnut Street in the morning. Portions of the shading
would extend past Pasadena Avenue onto the landscaped areas within the freeway rightof-way around 9:00 A.M. Shading would continue to extend north to shade the sidewalks
and a portion of the pavement along Walnut Street throughout the afternoon. By late
afternoon the shading would extend east across Fair Oaks Avenue, with the greatest
shadow impacts around 5:00 P.M. The only land uses that would be shaded are the uses
east of Fair Oaks Avenue, after the hour of 3:00 P.M. As noted above these land uses
include a gas station and the Marriott Courtyard Hotel. Sensitive Receptor 2, the pool and
courtyard to the east of the hotel structure, and portions of Sensitive Receptor 3, Memorial
Park, would be shaded by 5:00 P.M. Furthermore, as noted above, the existing 12-story
structure on the Project Site is the cause of the shading on these Sensitive Receptors, as
shown in Figure IV.D-12. Thus, the pool area and portions of Memorial Park would be
shaded during the fall equinox even without development of the proposed Project.
Furthermore, these Sensitive Receptors would not be shaded for more than four hours.
Therefore, impacts to shade-sensitive uses during the fall equinox would be considered
less than significant.
4. Cumulative Impacts
Cumulative impacts occur when impacts from a proposed project combine with
similar impacts from other past, present, or reasonably foreseeable projects in a similar
geographic area. As indicated in Section II, Environmental Setting, of this Draft EIR,
55 related projects have been identified within the Project study area. Collectively,
cumulative projects near the Project Site comprise a variety of residential (apartments,

condominiums, etc.), office, hotel, retail, restaurant, and entertainment uses, consistent
with existing uses in the area. Related Project No. 19 would be located directly north of the
Project Site and has the potential to create cumulative lighting, glare, and shading impacts
in combination with the proposed Project. No other related projects have the potential to
result in a cumulative light, glare, and shading impacts given their distances from the
Project Site. Related Project No. 19 would be developed on the currently vacant lots
directly north of the Project Site on Walnut Street with a Marriott Residence Inn.
(1) Light and Glare
It is anticipated that construction activities associated with Related Project No. 19
would occur between the hours of 7:00 A.M. and 7:00 P.M. Monday through Friday,
8:00 A.M. and 5:00 P.M. on Saturday, and not at all on Sunday, in accordance with PMC
Section 9.36.070. Given that the timeline of construction activities for Related Project No.
19 is unknown, there is a potential that this related project would be under construction as
the same time as the proposed Project. As a result, there is a potential for nighttime light
and glare from the proposed Project to combine with light and glare from Related Project
No. 19 and result in a cumulative impact at nearby sensitive receptors. However, to the
extent that concurrent construction does occur, it would primarily occur during the day and
would comply with the specified PMC requirements for construction activities. Therefore,
the potential for cumulative nighttime light and glare impacts would be less than significant.
With regard to daytime glare, as with the Project, any glare associated with construction of
Related Project No. 19 would be highly transitory and short-term, given the movement of
construction equipment and materials within the construction area and the temporary
nature of construction activities. In addition, large, flat surfaces that are generally required
to generate substantial glare are typically not an element of construction activities.
Therefore, cumulative daytime glare impacts during construction would also be less than
significant.
The proposed Project, combined with development of Related Project No. 19, would
increase ambient light levels in the Project area and would cumulatively introduce new or
expanded sources of artificial light. However, as previously described, the existing ambient
lighting levels in the Project vicinity are considered medium to high and, as such, the
Project and related project would not significantly alter the existing lighting environmental
currently experienced in the area. Additionally, as described above, the proposed Project
would be subject to applicable lighting guidelines and the City’s design review process,
which would control the Project’s potential artificial light sources to a sufficient degree so as
not to be considered cumulatively considerable. Related projects would be subject to the
same guidelines and review process to ensure that potential artificial light sources would
not significantly alter the light environment and result in cumulative impacts. With regard to
glare, both the proposed Project and related projects would be subject to design review to
ensure that significant sources of glare are not introduced. As such, adherence to these

IV.D Light, Glare, and Shading
measures would ensure that building materials would not have the potential to produce a
substantial degree of glare.
Therefore, cumulative light and glare impacts from
development of the Project and the related projects would be less than significant.
(2) Shading
As noted above, Related Project No. 19 would be located directly north of the
Project site and have the potential to create cumulative shading impacts in combination
with the proposed Project. Since shadows move in a northwesterly to northeasterly
direction, shading from the related projects would extend northwest toward Sensitive
Receptor 1, St. Andrew School, which is located on the northern portion of the block
surrounded by Fair Oaks Avenue, Chestnut Street, Raymond Avenue, and Walnut Street.
The shading by Related Project No. 19 would extend to shade portions of Sensitive
Receptor 1 during the late afternoon hours on the winter solstice, spring equinox, and fall
equinox. However, as shown in Figure IV.D-2 through Figure IV.D-12, the shadows cast by
the proposed Project would not extend to shade this receptor and, thus, there would not be
a combined impact from the proposed Project and related projects to shade-sensitive uses.
Therefore, cumulative shading impacts would be less than significant.
5. Mitigation Measures
As the proposed Project is not anticipated to result in any significant impacts related
to light, glare, or shading, no mitigation measures would be required.
6. Level of Significance After Mitigation
Project and cumulative impacts related to light, glare, and shading during Phase 1
and Phase 2 development as well as at Project buildout would be less than significant.
