1 IV.A.2 LIGHT & GLARE 1. INTRODUCTION This section describes the existing sources of nighttime illumination and glare on the Project site and in the surrounding area and evaluates potential changes resulting from Project implementation. Both terms are defined below. a. Light For purposes of this analysis, "light" refers to light emissions, or the degree of brightness, generated by a given source. Artificial lighting may be generated by point sources focused points of origin representing unshielded light sources or by indirectly illuminated sources of reflected light. Light may be directed downward to illuminate an area or surface; cast upward into the sky by an unshielded fixture and refracted (dispersed) by atmospheric conditions (sky glow); or cast sideways and outwards onto off site properties (light trespass or overspill). Sky glow and light overspill are considered forms of light pollution, which encompasses any adverse impacts of artificial lighting. The International Dark Sky Association defines light pollution as, Any adverse effect of artificial light including light trespass, sky glow, and glare, with secondary effects including decreased nighttime visibility and energy waste. Light trespass, sky glow, and glare are the subjects of this analysis. b. Glare Glare, or "unwanted source luminance", is defined as focused, intense light directly emanated by a source or indirectly reflected by a surface from a source. Glare is measured in terms of a luminance ratio, which expresses the degree of contrast between bright foreground objects and a darker background and is subjectively referred to as brightness or light intensity. The absolute measurement of light intensity on a given surface is objective, but human perception of that light intensity as a source of actual glare is dependent on the size, position, distance, and degree of visibility of a source from a given vantage point; the number of sources in a given area; and the luminance, or light levels, to which the eye of the beholder is adapted (i.e., background luminance levels). Glare is generally experienced as visual discomfort caused by high contrast in brightness levels in a given environment, or it may cause actual disability, such as a reduction in motorists ability to see or identify objects.

2 Daytime glare is typically caused by the reflection of sunlight from highly reflective surfaces at or above eye level. Reflective surfaces are generally associated with buildings clad with broad expanses of highly polished surfaces or with broad, light colored areas of paving. Daytime glare is generally most pronounced during early morning and late afternoon hours when the sun is at a low angle and the potential exists for intense reflected light to interfere with vision and driving conditions. Daytime glare may also hinder outdoor activities conducted in surrounding land uses, such as sports. Nighttime glare refers to direct, intense, focused light, as well as reflected light, and hampers visibility. Glare caused by direct sources of light generally originates from mobile and therefore transitory sources, such as automobiles. Nighttime glare may also originate from particularly intense stationary sources, such as floodlights. As with daytime sun glare, such intense light may cause undesirable interference with driving or other activities. 2. REGULATORY FRAMEWORK a. Los Angeles Municipal Code Several Los Angeles Municipal Code chapters govern nighttime illumination, as summarized below: Chapter 1, Article 2, Section A 5(k). All lights used to illuminate a parking area shall be designed, located, and arranged so as to reflect the light away from any streets and adjacent premises. Chapter 1, Article 7, Section Plans for street lighting shall be submitted to and approved by the Bureau of Street Lighting for subdivision maps. Chapter 9, Article 3, Section No exterior light source may cause more than two foot candles of lighting intensity or generate direct glare onto exterior glazed windows or glass doors; elevated habitable porch, deck, or balcony; or any ground surface intended for uses such as recreation, barbecue or lawn areas or any other property containing a residential unit or units. Chapter 1, Article 4.4, Section No sign shall be arranged and illuminated in a manner that will produce a light intensity of greater than three foot candles above ambient lighting, as measured at the property line of the nearest residentially zoned property.

3 b. Silver Lake Echo Park Elysian Valley Community Plan The Silver Lake Echo Park Elysian Valley Community Plan sets forth planning goals, objectives, and policies designed to maintain the character of the community. Those pertaining to lighting are summarized below. i. Design Policies for Individual Projects: Commercial Site Planning 1 Light and Glare 1. Install on site lighting along all pedestrian walkways and vehicular access ways. 2. Retail shops shall have well lit entries with directly accessible pedestrian access from the sidewalk, located at frequent intervals, with well lit exterior frontage. 3. Shield and direct on site lighting down onto driveways and walkways, away from adjacent residential uses. ii. Community Design and Landscaping Guidelines In addition to the establishment of design standards for individual projects, the Community Plan sets forth guidelines for improvements that affect the streetscape, public spaces, and public rightsof way in conjunction with private projects, since public spaces are considered to play an important part in the overall urban aesthetic of a community. c. Illuminating Engineering Society of North America Standards In order to address a broad range of settings and scenarios, the Illuminating Engineering Society of North America (IESNA) has developed light level thresholds based on existing ambient conditions in a given location. These recommendations for maximum off site light increases take into account existing conditions, distinguishing between intrinsically dark areas, estate/rural areas, suburban areas, and urban/pedestrian activity areas. For these differing environments, respectively, the Illuminating Engineering Society of North America recommends average light levels (i.e., ambient conditions plus project related increases) of 1.0, 1.5, 2.0, and 2.5 foot candles and maximum light levels of 4.0, 6.0, 8.0, and 10.0 foot candles. 2 Since the Project site is in an urban 1 City of Los Angeles, General Plan, Silver Lake Echo Park Elysian Valley Community Plan, Chapter V, Urban Design (2004), V 6. 2 A foot candle is a common unit of measurement of light intensity, or illuminance, used in the engineering industry and cited in building codes. It represents the light intensity cast on a surface by a one candela source one foot away, and is used to calculate adequate lighting levels of workspaces in buildings or outdoor spaces. City of Los Angeles IV.A.2 3 Barlow Hospital Replacement and Master Plan Project

4 area, the recommended off site ambient light levels should therefore not exceed 2.5 foot candles and the maximum light levels should not exceed 10.0 foot candles. 3. EXISTING CONDITIONS The Project site is located in the Echo Park community just west of Dodger Stadium and south of the 575 acre Elysian Park. An early residential suburb of Los Angeles, Echo Park is now characterized by a mix of land uses. Existing light and glare conditions on the Project site and in the Project vicinity are described below. a. Project Site and Nighttime Illumination Levels As discussed in Section II, Project Description, of this and illustrated in Figures II 2 through II 5 therein, the 25 acre Project site occupies a portion of a narrow valley south of Elysian Park. The Project site is bisected by Stadium Way and occupies a 10.6 acre eastern parcel and a 14.2 acre western parcel. The eastern Project site is bounded by Scott Avenue on the northeast and Boylston Street on the southeast; the western Project site is bounded by Elysian Park Drive on the west. Nighttime illumination levels are relatively low on the Project site. Sources of nighttime lighting on the eastern Project site include visible interior lighting and exterior building security lighting associated with the two story hospital building and the scattered buildings used for hospital offices or meeting space; high mast light fixtures (i.e., multiple light fixtures mounted atop poles of approximately 55 feet in height or more) within the on site surface parking lots, especially in the large lots serving hospital staff, patients and visitors at the southern end of the parcel; and lighted pedestrian walkways. The hospital operates 24 hours per day, seven days per week, and therefore the hospital building and parking lots remain lighted at night, but the level of nighttime activity is generally low. Ancillary hospital buildings are only lighted when in use in the evening. Vehicles arriving at and departing the hospital at night represent an additional source of light and, potentially, glare. On the western Project site, few or none of the buildings at the bottom of the slope along Stadium Way are in use and therefore most are not lighted at night. The two single family residences at the top of the slope on Elysian Park Drive are occupied, and sources of nighttime lighting include visible interior lighting and exterior building security and ornamental lighting. There are no parking lots on the western Project site that are illuminated at night, and the few pedestrian walkways near Stadium Way are not usually lighted at night since the buildings are rarely in use. City of Los Angeles IV.A.2 4 Barlow Hospital Replacement and Master Plan Project

5 Because of the Project site s location within a narrow, steep sided valley and the general concentration of on site lighted buildings and parking lots near the center of the site along Stadium Way, lighted features on the Project site are currently only visible from certain vantages in the Project area: to motorists traveling north or south along Stadium Way and along Boylston Street between Stadium Way and Scott Avenue; from Elysian Park Drive residences west of the Project site; and to a very limited extent, the closest one or two Boylston Street residences to the north. b. Project Vicinity and Nighttime Illumination Levels Land uses surrounding the Project site include Elysian Park to the north; single family residences on Boylston Street to the northeast; Dodger Stadium and surface parking to the east and southeast; and to the west, a neighborhood of single family and multi family residences, as well as Elysian Park s Victory Memorial Grove and Overlook, on Elysian Park Drive. As discussed below, the highest ambient nighttime lighting levels in the Project vicinity are found along major area roadways and within Dodger Stadium to the east (during game nights and special events), and to the southwest, along Elysian Park Drive and Sunset Boulevard. The residential neighborhoods south and west of the Project site exhibit relatively lower nighttime light levels, with the lowest nighttime light levels found in Elysian Park to the north. Stadium Way, which bisects the two Project site parcels, is lined with streetlights in the Project vicinity, with stoplights at the intersection with Scott Avenue at the northern end of the Project site. i. North: Scott Avenue, Elysian Park, and Boylston Street Residential Neighborhood Elysian Park begins north of Scott Avenue, which forms the northern Project site boundary. As previously discussed, Elysian Park is the City s second largest park and contains numerous recreational facilities. Park facilities near the Project site include Montecillo de Leo Politi Picnic Area, which include unlighted recreational facilities, tennis courts, and a softball backstop), picnic grounds, and parking. Ambient nighttime light levels in Elysian Park are very low since most facilities close to the public at dusk. Stadium Way and Academy Road are, however, brightly illuminated where they pass through the park. Boylston Street terminates in a cul de sac overlooking the Project site near its northeastern corner. This short segment of Boylston Street is developed with single family homes and lined with streetlights. During nights when no games or other events are held at adjacent Dodger Stadium, ambient nighttime light levels in this neighborhood are low to moderate. However, because of its City of Los Angeles IV.A.2 5 Barlow Hospital Replacement and Master Plan Project

6 proximity to Dodger Stadium and its surface parking lots, approximately 200 feet to the east, the neighborhood experiences considerably higher ambient light levels on Dodger game nights and when other evening events are hosted at Dodger Stadium. ii. East/Southeast: Dodger Stadium The highest nighttime illumination levels are found immediately east of the Project site at Dodger Stadium. Constructed between 1959 and 1962, the 56,000 seat stadium and its 21 terraced surface parking lots, accommodating 16,000 cars, occupy approximately 352 acres at slightly higher elevation (from 10 to 50 feet) than the Project site. Baseball season runs approximately 26 weeks, from April through October, followed by potential post season games in October. As a major league team, the Dodgers play 162 games per season, with half of those home games hosted at Dodger Stadium. The stadium also hosts special events such as the World Baseball Classic, other sporting events, concerts, and ceremonies requiring large venues. Major fixed light sources associated with the stadium include high mast parking lot light standards; stadium lights; the stadium scoreboard; strobe lights and other special effects used during games; and exterior stadium and ancillary building security lighting. During game nights and when other nighttime events are hosted, light levels on the stadium property are very high, although the Dodgers replaced their stadium lighting in 2008 to reduce by 95 percent the amount of light overspill beyond the actual stadium. 3 Vehicle headlights of stadium visitors during arrival and departure also contribute substantially to the ambient nighttime light levels on game/event nights in the Project vicinity. Elysian Park Avenue, located immediately south of the Project site, terminates in and serves as the major access driveway for the stadium parking lots and therefore contributes traffic to Stadium Way. Moreover, Boylston Street, east of the Project site, serves as a cut through roadway between these access roads for motorists seeking to avoid Stadium Way. iii. South/Southwest: Elysian Park Avenue/ Sunset Boulevard Elysian Park Avenue, south of the Project site, is a Major Highway Class II with three to four travel lanes in each direction and connects Sunset Boulevard with Dodger Stadium. Elysian Park Avenue is brightly lighted at night, especially at intersections with Stadium Way and Sunset Boulevard. South of Elysian Park Avenue, mixed single family and multi family residential neighborhoods are 3 Los Angeles Dodgers website, Dodger Stadium History City of Los Angeles IV.A.2 6 Barlow Hospital Replacement and Master Plan Project

7 characterized by low to moderate ambient levels of nighttime lighting; light sources include street lighting and exterior security or decorative lighting typical of private residences. Sunset Boulevard, also a Major Highway Class II, is a commercial corridor and brightly illuminated at night. iv. West: Elysian Park Drive The area west of the western Project site is a predominantly single family and multi family residential neighborhood, with single family residences and several apartment buildings on Elysian Park Drive immediately adjacent to the Project site. Light levels are low to moderate in these neighborhoods, with light sources limited to street lights and exterior building security or decorative lighting. The southern end of the western Project site is bordered by Victory Memorial Grove, a scenic outlook and WWI memorial that is part of Elysian Park. The northern end of the western Project site abuts the southern edge of Elysian Park. Park facilities are closed to the public after dusk and unlighted. c. Light Sensitive Uses in the Project Vicinity Some land uses are considered light sensitive receptors, including residences, hotels, or hospitals, since minimal nighttime illumination levels may be essential to the proper function, use, or enjoyment of these uses, or may be necessary for commerce. Sensitive receptors in the Project vicinity include the single family residences on Boylston Street to the northeast of the Project site, and the single family and multi family residences along Elysian Park Drive west of the western Project site. Park facilities are not considered sensitive to light intrusion since they are unoccupied at night. The existing hospital on the Project site is also considered a sensitive receptor. d. Glare The Project site is relatively lightly developed and, for the most part, not brightly illuminated at night. Sources of moderate potential for daytime glare include the hospital s surface parking lot, which encompasses several acres of paved area, and the two story hospital, which is clad with white stucco. High mast hospital parking lot lighting is the only potential source of nighttime glare. Off site, the presence of glare varies with the land uses surrounding the Project site. Dodger Stadium s banks of stadium lights, and the lighted scoreboard can represent considerable sources of glare in the Project area for viewers looking east, when the stadium is in use. To a lesser degree, high mast parking lot lighting surrounding Dodger Stadium may also create glare when in use. City of Los Angeles IV.A.2 7 Barlow Hospital Replacement and Master Plan Project

8 Street lights along Stadium Way, Scott Avenue, and Boylston Street may also represent sources of glare for motorists and residents of the Boylston Street neighborhood. Because of the presence of Elysian Park to the north of the Project site, and the low density of development and buildings no longer in use on the western Project site, there are no other sources of glare in the Project area. 4. IMPACT ANALYSIS a. Methodology To determine the potential for proposed Project related nighttime lighting and glare impacts, a survey of land uses in the vicinity of the proposed Project was undertaken and sensitive receptors in proximity to the Project site were located. The existing ambient nighttime light levels on the Project site and at nearby sensitive receptors, as well as the existence of glare generating building or landscape features on site or in the Project vicinity, were characterized. New sources of nighttime lighting or possible glare that would be introduced by the proposed Project were identified, and the extent of light spillover or glare affecting off site sensitive receptors was evaluated. b. Significance Thresholds Appendix G of the State CEQA Guidelines provides sample questions for use in an initial study to determine a project s potential for environmental impacts. According to the sample questions included in Appendix G under Section I, Aesthetics, a project could have a potentially significant impact if it results in: I.d) The creation of a new source of substantial glare that would adversely affect day or nighttime views in the area. The City of Los Angeles does not define quantitative thresholds for determining off site nighttime lighting impacts for a project. Instead, the City of Los Angeles CEQA Thresholds Guide indicates that the determination of significance shall be made on a case by case basis, considering the following factors: The change in ambient illumination levels as a result of project sources; The extent to which project lighting would spill off the project site and affect adjacent lightsensitive areas; City of Los Angeles IV.A.2 8 Barlow Hospital Replacement and Master Plan Project

9 The City of Los Angeles CEQA Thresholds Guide does not explicitly address glare in its qualitative thresholds for Nighttime Illumination. Based on these factors, the proposed Project would have a significant impact related to nighttime lighting or glare if: LIGHT 1 LIGHT 2 LIGHT 3 Project lighting would substantially increase ambient illumination levels in off site areas surrounding the Project site. Project lighting would spill off the Project site and substantially adversely affect a light sensitive land use and associated activity. New sources of Project glare would substantially adversely affect day or nighttime views in the Project area. c. Project Design Features The proposed Project would introduce new sources of nighttime lighting sources within the eastern and western Project site. As shown in Figure II 6, Proposed Site Plan, in Section II, Project Description, of the, the proposed replacement hospital, administration and support facility, and skilled nursing facility would be located on a proposed 3.25 acre Hospital Parcel at the southern end of the eastern Project s site. These uses would operate 24 hours per day, 7 days per week and would be illuminated at night. The hospital and administration building would be four stories tall, or approximately 51 feet in height above grade; the skilled nursing facility would occupy a two story building with parking podium on the first level. Sources of nighttime lighting in the proposed Hospital Parcel would include visible illuminated building interiors; exterior building security and decorative façade lighting; lighted pedestrian pathways; illuminated monument, building, and other signage; high mast light standards in the proposed hospital surface parking lot; and, when the skilled nursing facility is constructed, lighted structured parking. The proposed Project would retain nine existing buildings (one story cottages and buildings) plus some of the original landscape in a separate proposed Historical Parcel, to be adapted for reuse as offices and facilities for use by the hospital, residential, and Echo Park communities. Buildings may be used during evening hours. Nighttime lighting in this portion of the Project site would include visible interior illumination of buildings, exterior security and decorative façade lighting, lighted pedestrian walkways, and illuminated signage. City of Los Angeles IV.A.2 9 Barlow Hospital Replacement and Master Plan Project

10 The remainder of the Project site would be developed with a mix of residential and commercial uses. Parcels 1 12, shown in Figure II 6, Proposed Site Plan, in Section II, Project Description, would be developed with residential condominium buildings four stories tall, or 75 feet in height above adjacent grade. Parcel 7 would also include approximately 15,000 square feet of ground floor neighborhood commercial uses. Parking on these parcels would be partially subterranean with some at grade podium parking. Sources of lighting would include visible interior building illumination, exterior building security and decorative facade lighting, lighted pedestrian walkways and common areas such as courtyards and swimming pools, and lighting along internal driveways and roadways and at Project site entrances. Within Parcel 13 on the western Project site, the three townhome buildings on Elysian Park Drive would be three stories or 35 feet in height. Sources of lighting would include visible interior illumination and exterior building security and decorative lighting. The two existing single family homes in this portion of the Project site would remain. The remainder of Parcel 13, comprising the steep slopes in the Project site s interior, would remain undeveloped and would not be lighted at night. Approximate light levels for proposed on site development would comply with Illuminating Engineering Society of North America recommendations and would not exceed the following: Building entries and exterior surfaces: 0.5 foot candles Internal pedestrian walkways and common Areas: 0.5 to 1 foot candle Surface parking Areas: 1 foot candle Internal roadways: 1 to 2 foot candles Project lighting would comply with the following recommendations of the Illuminating Engineering Society of North America: Select luminaires emitting little to no light above the plane of the horizon; Avoid excessively bright spots on ground or surfaces; Limit the use of non cutoff luminaires; Turn off non critical lighting late at night; and City of Los Angeles IV.A.2 10 Barlow Hospital Replacement and Master Plan Project

11 Use internal or external shielding, such as louvers, hoods, or other screening devices, to minimize uplight and resulting sky glow when luminaires need to be tilted or aimed. Proposed development on the Project site would use building materials with low reflectivity properties, and would not introduce large expanses of glass or light colored surfaces that could generate glare perceptible from off site locations. Setbacks from surrounding roadways and the incorporation of large landscaped expanses into the site design further reduce the potential for Project glare generation. d. Project Impacts LIGHT 1 LIGHT 2 Would Project lighting substantially increase ambient illumination levels in off site areas surrounding the Project site? Would Project lighting spill off the Project site and substantially adversely affect a light sensitive land use and associated activity? Construction Construction of the proposed Project would occur over an approximately 10 year period, with one or more on site parcels developed simultaneously. During this time, some nighttime lighting would be maintained on individual construction sites for security purposes. On site construction lighting would represent a marginal increase in existing ambient nighttime light levels as measured at sensitive receptors surrounding the Project site because of the small size of the construction sites(s) lighted at any given time; the distance and/or intervening topography between most onsite construction and off site sensitive receptors; and the already high ambient light levels along Stadium Way, to the east at Dodger Stadium on nights when games or other events are hosted, and to the southwest along Elysian Park Boulevard. Furthermore, construction lighting would be temporary and removed upon completion of construction. Therefore, construction lighting would not substantially increase the ambient illumination levels in off site areas surrounding the Project site through light spillover or sky glow or interfere with off site activities, and impacts would be less than significant. Operation As discussed above under Subsection c, Project Design Features, the proposed Project would introduce a variety of permanent new sources of lighting to the Project site. Generally, the topography of the Project site, which occupies the low point of a narrow valley bisected by Stadium City of Los Angeles IV.A.2 11 Barlow Hospital Replacement and Master Plan Project

12 Way, severely constrains the influence Project related light sources would have on off site uses. Moreover, the proximity of Dodger Stadium increases light levels in the Project area on nights when games or other event are being hosted, and at such times Project lighting would be less noticeable from off site locations. The highest on site light levels would be associated with the replacement hospital, skilled nursing facility, and surface and structured parking facilities on the proposed Hospital parcel, at the southern end of the eastern Project s site. This area of the Project site is bordered by Stadium Way and the Boylston Street entrance to Dodger Stadium, both of which are already illuminated to moderately high levels at night. No off site sensitive receptors are located near the proposed Hospital parcel, and therefore related light sources would not substantially increase off site light levels through light spillover or sky glow. Within the proposed Historical Parcel, existing buildings and landscaping would remain largely intact. No major sources of nighttime lighting are planned for this area and associated light levels are not expected to substantially increase. As with the proposed Hospital Parcel, the proximity of this portion of the Project site to brightly lighted Stadium Way and its distance from any nearby offsite light sensitive receptors further reduced the potential for any substantial increase in off site ambient light levels. Impacts would be less than significant. The only sensitive receptors near the eastern Project site are the single family residences on Boylston Street to the northeast. The nearest proposed development on the Project site, at the northern end of the eastern Project site, would be separated from these residences by a horizontal distance of 160 feet and an elevation differential of approximately 25 feet, since the residences sit above the Project site atop a small ridge. As previously noted, these residences are located approximately 200 feet west of, and slightly higher than, the nearest Dodger Stadium parking lots and experience moderate to high light levels during game and event nights. Because of distance, topography, and (on game and event nights) already high ambient light levels, Project light sources would not substantially increase ambient illumination levels in this residential neighborhood through light spillover or sky glow or increase light levels on an off site residence by one or more foot candles. Impacts would be less than significant. On the western Project site s, most development would be concentrated at the bottom of the slope along Stadium Way, too distant from any off site sensitive receptors to increase ambient light levels at those locations. The three story townhome buildings proposed at the top of the western Project site s slope, on Elysian Park Drive, would be between 35 and 60 feet from the nearest single family City of Los Angeles IV.A.2 12 Barlow Hospital Replacement and Master Plan Project

13 and multi family residences across Elysian Park Drive, at the same elevation. Townhome lighting sources are expected to be similar in type and illumination level to lighting associated with those existing residences (i.e., visible interior illumination and exterior building security and decorative lighting). Thus, while townhome lighting sources would be visible from off site residences and would incrementally increase ambient illumination levels in this area, the increase is expected to be minor and would constitute a less than significant impact. The proposed townhomes would not increase light levels on the Elysian Park Drive residential properties by one or more foot candles, and would therefore comply with City of Los Angeles ordinance requirements. Elevations fall away rapidly west of Elysian Park Drive, precluding any impacts from Project site light sources on these land uses. LIGHT 3 Would new sources of Project glare substantially adversely affect day or nighttime views in the Project area? Construction Construction activities are not anticipated to create sources of glare that could affect visibility in the Project area, because of the depth of building setbacks from surrounding roadways, the use of building materials that are low reflectivity in nature, and (as noted above under thresholds LIGHT 1 and 2, construction is not expected to involve bright light sources that would be visible from offsite locations. Therefore, impacts due to glare generation and interference with the performance of an off site activity or adverse effects on views would be less than significant during construction. Operation No sources of substantial glare are anticipated with implementation of the proposed Project. The setbacks of proposed campus structures from surrounding roadways as well as the presence of intervening landscaping and structures would inhibit any new sources of potential daytime glare from affecting off campus uses or activities. Only low reflective building materials are anticipated to be used. Therefore, Project related glare impacts and the potential for interference with the performance of an off site activity or adverse effects on views would be less than significant. e. Mitigation Measures Although light and glare impacts were determined to be less than significant, the following measures would further reduce ambient light levels in the Project vicinity and the potential for offsite glare impacts. City of Los Angeles IV.A.2 13 Barlow Hospital Replacement and Master Plan Project

14 MM LIGHT 1 The use of nighttime lighting during Project construction shall be limited to only those features on the construction site requiring illumination. MM LIGHT 2 All security lights shall be properly shielded and projected downwards during construction such that light is directed only onto the work site. MM LIGHT 3 All outdoor lighting shall be directed downward to illuminate the intended surface (i.e., common areas, pedestrian pathways and other high traffic areas). MM LIGHT 4 All outdoor lighting shall be equipped with louvers, shields, hoods, or other screening devices. MM LIGHT 5 The applicant shall use exterior building materials and facades which eliminate or minimize highly reflective materials. At the time of plan check review, building materials shall be reviewed to assure that they do not exceed the reflectivity of standard building materials. If the applicant should desire to use more reflective materials in locations isolated from surrounding roadways, adequate analysis must be presented to the Department of Building and Safety to determine that the building location would not cause glare for motorists or a nearby population. f. Level of Impact After Mitigation Project lighting and glare impacts were determined to be less than significant and while no mitigation is required to reduce impacts below the threshold of significance, the above mitigation measures are intended to further ensure Project lighting and glare impacts. No significant, unavoidable impacts related to nighttime illumination and glare would result from Project implementation. g. Cumulative Impacts A cumulative light and glare impact would occur if any related projects identified in Section III, General Description of Environmental Setting and located within the proposed Project s immediate surroundings would contribute to a cumulative increase in ambient nighttime light levels or glare generation in that area. As shown in Figure III 1, the majority of related projects is not located in the near Project vicinity and would not contribute to cumulatively significant light or glare conditions. City of Los Angeles IV.A.2 14 Barlow Hospital Replacement and Master Plan Project

15 One project, the Dodgers Next Fifty Years, is adjacent to the Project site and has the potential to increase ambient illumination levels in the Project area and/or introduce sources of glare. The Next Fifty Years proposes to redevelop Dodger Stadium parking lots with a variety of commercial and entertainment uses, which would presumably introduce new sources of nighttime lighting on the stadium property. Details of this project have not yet been made public and the potential impact cannot be precisely evaluated at this time. Even so, it is not expected that proposed Project light sources would result in a considerable contribution to contribute cumulatively significant nighttime illumination and glare impacts, because of the nature of topography in the Project area and the distance between proposed development on the Project site, Dodger Stadium, and nearby sensitive receptors in the Project area.
