1 POINT LOMA HIGH SCHOOL WHOLE SITE MODERNIZATION AND ATHLETIC FACILITIES UPGRADE PROJECT Appendix B2 Addendum to Prepared by T&B Planning Consultants December 18, 2015

2 JN December 18, 2015 Erich Lathers BRG Consulting, Inc. 304 Ivy Street San Diego, CA RE: ADDENDUM TO LIGHTING IMPACT STUDY FOR POINT LOMA HIGH SCHOOL FOOTBALL STADIUM PROJECT Dear Mr. Lathers: T&B Planning previously prepared a (LIS) for the Point Loma High School Football Stadium project (herein, 2014 project ), dated May 20, 2014 (herein, 2014 LIS ). Since the preparation of the 2014 LIS for the 2014 project, we understand that the initial design of the stadium lighting system has been modified; specifically, the location of each of the four (4) field lighting elements have been relocated, and the height of each lighting element has been reduced (from 90 to 70 ). In addition, the orientation of the lighting elements has been modified to account for the new lighting standard locations and mounting height. Additionally, the number of luminaires per pole directed towards the football field has been reduced (from 15 to 14 luminaires), and an additional two (2) luminaires per pole are proposed to provide up-lighting. Four luminaires per pole provide egress during power shortages, and would not be used except during power shortages. The revised project also now includes four new 20-foot tall stadium lighting standards at the home team (southern) bleachers (G1 through G4 on Figure 1, Revised Lighting Plan), with two luminaires provided on each the two outside poles (G1 and G4) and one luminaire each provided on the two interior poles (G2 and G3). An additional two 30-foot tall lighting standards also are proposed for the visitor bleachers on the north side of the field (G5 and G6 on Figure 1), with each element containing two luminaires per pole. In order to address these changes, this letter is intended to serve as an update to the May 20, 2014 LIS and provides an analysis of potential environmental impacts that may result from the lighting elements constructed as part of the currently proposed project (hereafter, Project ). Project Location, Site Conditions, and Surrounding Environment Point Loma High School is located within a peninsular community in the Loma Portal section of Point Loma in the City of San Diego and is depicted on Figure 2, Regional Map. More specifically, the site is located on the southwest portion of the 13.5-acre Point Loma High School campus, and is bounded by Chatsworth Boulevard to the northwest, Voltaire Street to the southwest, and Clove Street to the southeast, as depicted on Figure 3, Vicinity Map. Figure 4, Aerial Photograph, shows the site in relation to the immediate surrounding land area. As shown on Figure 4, land uses within the vicinity include the remainder of the 13.5-acre Point Loma High School campus to the north, residential uses surrounding most of the high school campus, and commercial uses and a church located to the west along Chatsworth Boulevard. The Project improvement area is currently developed with an existing football stadium, a running track located around the perimeter of the football field, and associated stadium and athletic support facilities. Bleachers and a building housing a weight room are located on the southwestern edge of the running track. A composite steel beam and heavy timber retaining wall exists near the running track at the southwestern edge of the stadium, and a concrete retaining wall exists along the southern edge of the running track that extends along the southeastern portion of the natural turf practice field. To the northwest of the natural turf practice

3 ADDENDUM TO POINT LOMA LIGHTING IMPACT STUDY December 18, 2015 Page 2 of 17 field are basketball courts. A parking lot is located to the north of the natural turf practice field. Located west of the parking lot is a Reserve Officer s Training Corps (ROTC) building and the main gymnasium. A building housing classrooms is located southwest of the main gymnasium and ROTC building. Currently, there are no artificial lighting elements within the Project improvement area that provide illumination for the football field and/or track and there are no sources of substantial glare from the Project improvement area. The proposed improvement area is located in an urbanized, primarily residential neighborhood in Point Loma, which is developed with a variety of uses. To the west and northwest of the site is an existing residential neighborhood and commercial center featuring a number of small business including, but not limited to, an art gallery, flower shop, gym, and real estate office. To the southwest of the Project site, along Chatsworth Blvd., there are two apartment complexes and mixed use building with a ballet studio on the first floor and residential uses on the second floor. To the south and east of the Project site are residential neighborhoods bordering Voltaire Street and Clove Street. The remainder of the 13.5-acre Point Loma High School campus is located northeast of the Project improvement area. Street lighting and lighting for multifamily residential parking lots are prevalent throughout the surrounding area, and a street light is located at the intersection of Clove Street and Voltaire Street. In addition, external lighting exists for the commercial businesses located west of Chatsworth Boulevard. Overview of May 20, 2014 The 2014 LIS prepared in support of the 2014 project evaluated the potential to result in visual quality impacts related to artificial lighting and glare that would result from implementation of the 2014 project. Specifically, the 2014 LIS included a discussion of relevant lighting standards, plans, regulations and guidelines; a description of the existing lighting conditions and sensitive receptors surrounding the site; thresholds of significance for evaluating the potential significance of lighting and/or glare impacts; an assessment of potential adverse lighting effects; and mitigation measures determined necessary to reduce light and glare impacts to a level below significant. The 2014 LIS provided a complete description of the 2014 project as proposed at the time, including a description of the proposed lighting system. Figure 5, 2014 Conceptual Site Plan, depicts the site plan that was evaluated in the 2014 LIS. As described in the 2014 LIS, the proposed artificial lighting improvements were assumed to consist of the installation of the Musco Light-Structure Green sports lighting system at the football stadium. Two (2) light standards were proposed at the ends of each bleacher section on the northern portion of the football field and two (2) light standards were proposed at the ends of the bleacher section on the southern portion of the football field, as depicted on Figure 6, 2014 Lighting Plan. The four (4) lighting elements (F1, F2, F3, and F4 on Figure 6) were proposed to consist of 90-foot tall galvanized steel poles with lighting fixtures mounted at 90 feet. The maximum elevation of the lighting elements on the north side of the field were proposed to be approximately feet above sea level, while the maximum elevation of the lighting elements on the south side of the field were proposed to be approximately 263 feet above sea level. The 2014 project proposed the four lighting elements to be mounted with 15 luminaires each. In total, 60 luminaires were proposed for purposes of athletic stadium lighting. Each proposed luminaire was proposed to include a 1500-watt metal halide fixture, which would have produced an average luminous intensity of 134,000 lumens per lamp (Musco Lighting, 2013). In addition, the 2014 project proposed an external visor on each fixture to reduce glare and a reflective insert to focus light onto the playing field (Musco Lighting, 2014). Based on information provided by the San Diego Unified School District (SDUSD), it was understood

4 ADDENDUM TO POINT LOMA LIGHTING IMPACT STUDY December 18, 2015 Page 3 of 17 that the lighting elements under the 2014 project were assumed to be dimmed by approximately 9:00 pm, and extinguished entirely by approximately 10:00 pm. The 2014 LIS concluded that, based on the physical characteristics of the area surrounding the site and the design of the proposed light fixtures, implementation of the 2014 project would result in no impact associated with sky glow. An analysis of glare also was conducted, which concluded that the design elements of the proposed lighting system (i.e., incorporation of visors and reflective inserts), the high mounting light of the light fixtures that focus lights downward on the field of play would ensure that impacts due to glare to be less-than-significant. The 2014 LIS also included an extensive evaluation of the 2014 project s potential to result in light trespass impacts, which would result if the proposed 2014 project lighting elements were to expose nearby sensitive receptors (i.e., residential uses) to lighting levels in excess of the SDUSD s significance threshold. Specifically, impacts were described as significant and unavoidable if the illuminance produced by the project would exceed 0.8 foot-candles during pre-curfew hours (i.e., between dusk and 11:00 pm) and 0.2 footcandles during the post-curfew hours (i.e., between 11:00 pm and 7:00 am), as measured on the vertical and horizontal planes, at any adjacent residential use. For the purpose of the 2014 LIS, potentially impacted residences in the area surrounding the Point Loma High School football field were broken into seven housing blocks labeled with the letters A, B, C, D, E, F, and G. The term residence is used in this report to refer to the occupied portions of both single-family homes and multi-family dwellings. The location of Housing Blocks A through G is shown on Figure 7, Housing Blocks. These housing blocks include the residences located closest to the Point Loma High School football field, on Chatsworth Boulevard, Voltaire Street, and Clove Street. The 2014 LIS s analysis of potential impacts due to light trespass determined that residential Housing Blocks C, D, E, & G would be exposed to lighting levels in excess of 0.8 vertical foot-candles during pre-curfew hours, while residential Housing Blocks C, D, & E also would be exposed to lighting levels in excess of 0.8 horizontal foot-candles during pre-curfew hours. The 2014 LIS concluded the 2014 project would expose nearby residential Housing Blocks to significant and unavoidable lighting levels during pre-curfew hours (on both the vertical and horizontal planes). Although the estimate of lighting levels in the 2014 LIS did consider the attenuating effect of proposed landscaping elements, the 2014 LIS concluded that further reductions in lighting levels through Project design revisions were infeasible. The 2014 LIS also concluded that additional mitigation measures, such as the addition of barriers (vegetation or walls), were not feasible due to the proximity of affected homes to the Project boundary and the inability to effectively screen affected residences from the proposed lighting elements. The 2014 LIS further concluded that other potential mitigation measures, such as the provision of barriers (vegetation or light-blocking night shades) on individual residential lots/homes also was infeasible because the Lead Agency (SDUSD) has no control over property that is not owned by the SDUSD. Accordingly, the 2014 LIS concluded that impacts to sensitive receptors due to lighting elements would be significant and unavoidable during pre-curfew hours. The 2014 LIS did not identify any impacts during post-curfew hours (i.e., from 11:00 pm to dawn) because all proposed lighting elements were proposed to be extinguished by 11:00 pm. Based on the results of the 2014 LIS for the Project, it was concluded that implementation of the 2014 project would result in significant and unavoidable lighting impacts.

5 ADDENDUM TO POINT LOMA LIGHTING IMPACT STUDY December 18, 2015 Page 4 of 17 Revisions to the Project Since completion of the 2014 LIS, the SDUSD has modified the planned improvements for the football stadium. The revised site plan for the planned improvements is depicted on Figure 8, Revised Conceptual Site Plan. The revised Project consists of site modernization at Point Loma High School, which would provide improvements to the school campus and associated buildings. Specifically, the revised Project consists of the following: The demolition of the 800 building, an existing 2-story, 25,000 square feet building with a library/media center on the ground floor and eleven classrooms on the second floor, and replacing it with a new 3-story, 38,000 square feet building with a library/media center on the ground floor, ten classrooms on the second floor, and 10 classrooms on the third floor. The construction of a freestanding 150 square foot building to house the campus Main Distribution Frame (MDF). The renovation of the 200 building, an existing 2-story, 15,700 square foot classroom building. The renovation of the 300 building, an existing 2-story, 19,700 square foot classroom building. The creation of a security enclosure that will extend around the 200 and 300 buildings. The creation of a secure entrance portal for campus visitors from the Clove Street parking lot. The demolition of the unused Auto Shop and reconfiguration of the Clove Street parking lot to increase on-site parking capacity. General landscape and hardscape improvements within the northeastern portion of the Point Loma High School campus. Off-site improvements will consist of new curbs, gutters and sidewalks along Chatsworth Blvd. in the area fronting the 200, 300 and 800 buildings including a bus turn out along the frontage of 300 building. Additionally, the Project involves improvements to the athletic facilities on the campus to include the following: Installation of field lighting and grandstand (bleacher) lighting; Installation of a Public Announcement (PA) System; and Installation of an Electrical Unit Substation. As shown on Figure 8, the revisions to the plans since the 2014 project also include revised configurations and locations for the four (4) lighting elements proposed for illumination of the football field and surrounding track, and also includes the installation of four new stadium lighting standards to illuminate the bleachers along the south side of the track and the installation of two new stadium lighting standards to illuminate the bleachers along the north side of the track. Figure 1, Revised Lighting Plan, depicts the revised location of four (4) light elements and the six (6) locations of the proposed stadium lighting elements.

6 ADDENDUM TO POINT LOMA LIGHTING IMPACT STUDY December 18, 2015 Page 5 of 17 As shown in Figure 1 and Figure 8, and as summarized in Table 1, Point Loma High School Lighting System Summary, the height of each the four (4) field light poles (Poles F1, F2, F3, and F4) was reduced from 90 feet to 70 feet and the poles were relocated from the exterior circumference of the athletic track near the ends of each bleacher section to the interior circumference of the athletic track. The field lighting elements would include a total of 20 luminaires each. A total of 14, 630 watt (W) luminaires would be installed on each field lighting pole at a height of 70 feet, with each luminaire producing 65,400 lumens aimed at the field and track. Two 394 W (38,600 lumen) luminaires also would be installed at a height of 15' on each pole, and provide "uplighting" to illuminate the bottom of the football during punts and high passes. Two additional 394 W luminaires, each producing approximately 38,600 lumen, would be installed at a height of 60 feet, with two additional luminaires proposed at a height of 58 feet; these four luminaires would provide lighting for egress and only would be used during power failures, and would not be utilized when the other field lighting elements are active.

Additionally, a total of ten (10) luminaires would be installed on the six stadium lighting poles; four poles would be installed on the south side of the track (Poles G1, G2, G3, and G4 on Figure 1) at a height of 20 feet and two poles would be installed on the north side of the track (Poles G5 and G6 on Figure 1) at a height of

7 ADDENDUM TO POINT LOMA LIGHTING IMPACT STUDY December 18, 2015 Page 6 of feet. Stadium light poles G1, G4, G5, and G6 each would include two (2) 130 W luminaires, each producing 7,600 lumens and poles G2 and G3 each would include one (1) 130 W luminaire, each producing 7,600 lumens. All other specifications of the lighting system, including external visors and reflective inserts, are identical to what was described in the 2014 LIS. Basis for Determining Significance The following significance guideline is the basis for determining the significance of direct impacts to visual quality related to artificial lighting and glare: 1. The Project would create a new source of substantial light or glare which would adversely affect day or nighttime views in the area. The above-listed threshold for significance is based on Appendix G of the CEQA Guidelines, and is the same threshold of significance utilized in the 2014 LIS. This threshold addresses the potential for a project to produce a substantial amount of light which could result in adverse effects due to light pollution. It also addresses the potential for a project to produce glare which could result in discomfort or disability. For purposes of the 2014 LIS and this Addendum to the 2014 LIS, the proposed Project would be regarded as having an adverse lighting impact if it would produce a substantial amount of light pollution, including sky glow, light trespass, or glare (for example, by proposing poorly shielded light fixtures). Sky glow and glare impacts are evaluated according to the design (shielding, angular distribution of light, etc.) of the proposed lighting system, as the physical characteristics of the lighting system correlate directly to the contribution of sky glow and glare. Sky glow impacts would be considered significant under CEQA if the proposed artificial lighting installation would emit a substantial amount of upward light. Glare impacts would be considered significant under CEQA if the proposed artificial lighting fixtures would be unshielded and/or installed at a height or angle that would permit direct view of the main beam from off-site locations. According to the Institution of Lighting Engineers (ILE) and the Electric Power Research Institute (EPRI), light trespass varies according to surrounding environmental characteristics. Areas that are more rural in character, and therefore exhibit few existing artificial sources of light, are more susceptible to impacts resulting from the installation of new artificial lighting sources. By contrast, urbanized areas are characterized by a large number of existing artificial lighting sources and are therefore less susceptible to adverse effects associated with new artificial lighting sources. Therefore, different lighting standards are applied which vary according to the amount and intensity of existing lighting sources in the area. In order to determine appropriate lighting standards that are reflective of the existing lighting conditions, land uses are typically categorized into one of four Environmental Zones, which are described below: E1: Areas with intrinsically dark landscapes. This environmental zone includes national parks, areas of outstanding natural beauty, and rural areas. E2: Areas of low ambient brightness. This environmental zone includes outer urban and rural residential areas. E3: Areas of medium ambient brightness. This environmental zone includes urban residential areas. E4: Areas of high ambient brightness. This environmental zone includes urban areas with mixed residential and commercial uses with a high level of nighttime activity.

8 ADDENDUM TO POINT LOMA LIGHTING IMPACT STUDY December 18, 2015 Page 7 of 17 Based on these environmental zones, the ILE and EPRI have established recommendations for limiting light trespass onto adjacent residential properties. The recommendations established by the ILE and EPRI are summarized in Table 2, Obtrusive Light Limitations for Exterior Lighting Installations. As previously discussed, the Project site is located in an urban residential area and is characterized as an area of medium ambient brightness (E3 environmental zone). For purposes of analysis, light trespass will be evaluated against the recommendations established by the ILE and EPRI. Because there is no universally accepted standard for measuring and evaluating the significance of light trespass, this report will use the pre-curfew limits recommended by the EPRI and the post-curfew limits recommended by the ILE, as these limitations represent the most stringent standard by which Project impacts may be evaluated. Furthermore, the recommended limitations listed in Table 2 also will be applied to levels of horizontal illuminance. In urban residential environments, such as the area surrounding the Project site, a common adverse effect associated with light trespass is sleep disruption. As horizontal illumination assesses the amount of light falling on a horizontal plane (like a bed, for instance), it is considered to be an appropriate unit of measure for the proposed Project. The potential for sleep disruption is the critical component in determining the level of impact for light trespass. Accordingly, light trespass impacts would be considered significant under CEQA if illuminance produced by the Project would exceed 0.8 foot-candles during pre-curfew hours and 0.2 foot-candles during the postcurfew hours, as measured on the vertical and horizontal planes, at any nearby residential structure. Table 2 Obtrusive Light Limitations for Exterior Lighting Installations ILE ENVIRONMENTAL ZONE EPRI LIGHT TRESPASS, VERTICAL ILLUMINANCE PRE-CURFEW (DUSK-11:00 PM) POST CURFEW (11:00 PM 7:00 AM) E1 2 lx 0.2 fc 1 lx 0.1 fc E2 5 lx 0.5 fc 1 lx 0.1 fc E3 10 lx 0.9 fc 2 lx 0.2 fc E4 25 lx 2.3 fc 5 lx 0.5 fc E1 1 lx 0.1 fc 1 lx 0.1 fc E2 3 lx 0.3 fc 1 lx 0.1 fc E3 9 lx 0.8 fc 3 lx 0.3 fc E4 16 lx 1.5 fc 7 lx 0.6 fc lx = lux fc = foot-candles Source: Adapted from ILE (2005), EPRI (2000), IESNA (1999) As a frame of reference, a full moonlit night in rural areas with negligible ambient light would equal approximately foot-candles, while a typical 30-foot tall streetlamp would have an illumination of 1.3 foot-candles at a distance of 10 feet.

9 Methodology ADDENDUM TO POINT LOMA LIGHTING IMPACT STUDY December 18, 2015 Page 8 of 17 This report is based upon a photometric analysis conducted by the Project lighting system designer, Musco Lighting. The photometric analysis includes a quantification of the levels of illumination produced by the Project on both vertical and horizontal planes. This report assesses the levels of illumination produced by the Project s proposed lighting elements and evaluates the compatibility of the proposed illumination with the surrounding residential community. For the purpose of this analysis, potentially impacted residences in the area surrounding the Point Loma High School football field were broken into seven housing blocks labeled with the letters A, B, C, D, E, F, and G. The term residence is used in this report to refer to the occupied portions of both single-family homes and multi-family dwellings. The location of Housing Blocks A through G was previously shown on Figure 7. These housing blocks include the residences located closest to the Point Loma High School football field, on Chatsworth Boulevard, Voltaire Street, and Clove Street. Lighting levels affecting residences within these housing blocks were determined based on the structure s distance to the Point Loma High School football field, and the structure s elevation relative to the elevation of the football field, which is approximately 174 feet above sea level (Google Earth, 2015). Elevation is considered because the proposed lighting elements would affect residences differently depending on the structure s elevation relative to the lighting element. For residences located at an elevation at or below the Point Loma High School football field, Project-related lighting levels increase as the home s elevation relative to the football field decreases. For residences located at an elevation above that of the Point Loma High School football field, Project-related lighting levels decrease as the structure s elevation increases relative to the football field. Additionally, lighting levels decrease as the structure s distance from the football field increases. To assess the level of illumination affecting the residences within Housing Blocks A through G under the revised Project, lighting levels were assessed at elevations both above and below the Point Loma High School football field at increments of 10 feet. However, the computer modeling software used to estimate lighting levels does not take into consideration topography, which has an effect on the lighting levels (as noted above). In order to assess the lighting levels affecting residences at different elevations, the Project s lighting engineer adjusted the height of the light poles to create a number of scenarios to simulate these elevation differences. Illumination levels were therefore evaluated for homes with elevations greater than the football field (+10, +20, and +30 feet), elevations lower than the football field (-10, -20, and -30 feet), and the same elevation as the football field (field level). In an effort to conservatively assess lighting levels affecting nearby residences, the elevation of each home site was rounded down to the nearest scenario described above. For example, lighting levels for a home located at an elevation approximately 16 feet above the football field are based in the illumination levels for the +10 feet scenario. Similarly, a home located at an elevation eight (8) feet below that of the football field is analyzed herein using the -10 feet scenario described above. These assumptions provide for a worst-case analysis of potential lighting impacts of the proposed Project.

10 Analysis of Project Effects ADDENDUM TO POINT LOMA LIGHTING IMPACT STUDY December 18, 2015 Page 9 of 17 Provided below is an analysis of the revised Project s potential to result in significant lighting impacts associated with the artificial lighting intended to be constructed at the site, along with a brief discussion of and comparison to the analysis and conclusions reached in the 2014 LIS. Sky Glow The Project site is located in an urbanized area that is not especially sensitive to the effects of sky glow. In addition, the Project site is located approximately 48 miles southwest of Palomar Mountain Observatory and would therefore have less potential to impact operations at the observatory than more closely-situated properties (Google Earth, 2015). Regardless, the proposed Project would result in the erection of four 70-foot tall light field lighting standards as well as four 20-foot tall and two 30-foot tall bleacher lighting standards. On each of the 70-foot field lighting elements, a total of 14 luminaires per pole would be directed at the track, while two luminaires per pole providing up-lighting and an additional four luminaires that would be used only during power failure. Additionally, four bleacher light poles would be installed on the south of the track at a height of 20 feet, and two light poles would be installed on the north end of the track at a height of 30 feet. The height of the proposed field and bleacher lighting standards would allow for each luminaire to be mounted with a narrow beam angle, which would focus most of the field light downward. In addition, the proposed field luminaires would feature a highly efficient reflector and visor; the reflector would focus light toward the field, while the visor would minimize upward light. These design features would minimize sky glow to the maximum feasible extent associated with field and bleacher lighting elements. As noted above, each of the 70-foot tall field lighting elements would include two luminaires each that are directed upward, which is a change from the project evaluated in the 2014 LIS, which did not include uplighting because the heights of the poles (90 feet) were sufficient to illuminate all field activities. Thus, the total of eight luminaires that would provide up-lighting are intended to ensure adequate illumination occurs at a height of up to 90 feet above the field. Each of these 394 W luminaires would produce 38,600 lumens and would be directed upward; thus, these up-lighting elements have the potential to create adverse effects associated with sky glow. Based on calculations of the up-lighting elements conducted by the Project s lighting engineer (Musco Lighting), these up-lighting elements (combined) would produce a maximum of approximately 7.8 foot-candles at a distance of approximately 60 feet. Illumination produced by the lighting elements would be reduced in accordance with the following formula: E = l/d 2, where E is the lighting levels in foot-candles, l is the lighting intensity of the fixture (in candelas), and d is the distance from the lighting fixture. Based on calculations produced by Musco, the combined up-lighting elements would produce a total of approximately 28,080 candelas; thus, up-lighting illuminance would be reduced to below 0.8 foot-candles at a distance of approximately 247 feet above the football field. Although the Project s up-lighting elements would result in adverse effects due to sky glow, the primary environmental concern associated with sky glow is whether sky glow would interfere with nighttime astronomical observations, particularly observations at the Mt. Palomar Observatory. Based on information provided in the County of San Diego s Guidelines for Determining Significance and Report Format and Content Requirements: Dark Skies Guidelines (January 15, 2009), the Point Loma High School site is located in an urban core portion of the Southern California region, where only the brightest stars in the sky

11 ADDENDUM TO POINT LOMA LIGHTING IMPACT STUDY December 18, 2015 Page 10 of 17 are visible. Given the level of background sky glow, it is unlikely that Project up-lighting elements would result in a substantial change in the amount of light pollution or sky glow within the surrounding area. Furthermore, the Project site is located more than 45 miles from the Mount Palomar Observatory, which is the closest astronomical observation facility to the Project site. Numerous jurisdictions throughout Southern California have identified a 45-mile radius or less from the observatory as the areas in which the generation of sky glow could impact observations at the observatory, and have adopted light pollution regulations accordingly. These jurisdictions include the City of San Diego (which utilizes a distance of 30 miles), County of Riverside, City of Menifee, City of Wildomar, and others. Accordingly, because Project-related up-lighting elements would only create sky glow illumination exceeding 0.8 foot-candles at a distance of up to 247 feet from the football field, the Project is located in an urban area with very high levels of background sky glow, and the Project s lighting elements would not affect observations at the Mt. Palomar Observatory, impacts associated with sky glow would be less than significant. Glare The proposed Project would introduce new outdoor artificial lighting elements, which have the potential to result in glare if the main beams of proposed lighting elements (i.e., the portion of the lamp with the greatest illuminance) are visible from off-site locations, resulting in excessive, uncontrolled brightness. However, many of the same design features that would minimize sky glow also would minimize glare impacts. The high mounting heights of the light fixtures would allow the light fixtures to be aimed at a steep angle that would focus the main beam of the lamp onto the football field. In addition, the light fixtures would feature a reflective insert that would further focus the main beam of the lamp onto the field of play or bleachers (except for up-lighting elements, as discussed above). Furthermore, each light fixture would be fitted with a visor that would minimize and/or block a direct line-of-sight to the main beam of the lamp from off-site locations. These design features would ensure that a direct line-of-sight to the main beam of the lamp would be minimized and/or blocked from off-site locations. Although new sources of outdoor artificial light would be introduced into the community, the design of the proposed lighting system would ensure that off-site residential land uses and motorists would not be exposed to excessive, uncontrolled brightness. Consistent with the 2014 LIS, glare impacts would be less than significant. Light Trespass Implementation of the Project would result in the construction of four artificial light standards. The proposed artificial lighting system has been specifically designed to minimize light trespass. The high mounting height of field lighting elements (70 feet) and bleacher lighting elements (20 to 30 feet) would allow the lamps to be installed with a narrow beam angle to direct light downward, onto the football field and away from adjacent residential properties. In addition, each luminaire would feature a reflective insert and an external visor, which would capture and redirect primary light onto the field and would result in less spill light off-field. Furthermore, the lighting elements have been relocated to the inside (football field side) of the track, instead of constructing the lighting elements on the outside of the track, as was evaluated in the 2014 LIS. The relocation of the lighting elements would serve to reduce the Project s potential for light trespass as compared to the project evaluated in the 2014 LIS.

12 ADDENDUM TO POINT LOMA LIGHTING IMPACT STUDY December 18, 2015 Page 11 of 17 The proposed artificial lighting system would be used to illuminate the football field as well as track events and practices that may occur during non-daylight hours. There is the potential for the football field to host additional evening events on an annual basis, including routine practices and playoff games. The facility also is intended to be rented out for community events. Based on typical operational characteristics at other high school facilities within the SDUSD, it is anticipated that field lighting would be completely extinguished by approximately 11:00pm. In no case would the artificial lighting elements for the football field be used between the hours of 11:00pm and dawn. Areas surrounding the Project site contain light sensitive uses (residential homes) that may be impacted by spill light. These areas contain residential neighborhoods made up of both single-family and multi-family homes that have the potential to be adversely affected by light trespass effects associated with the Project s proposed lighting elements, on both the vertical and horizontal planes. Potentially affected neighborhoods have been broken up into six Housing Blocks (refer to Figure 7) for analysis. Potential impacts to each of these Housing Blocks are addressed below. The following discussion analyzes the potential for the lighting system constructed by the Project to result in adverse light trespass impacts for adjacent light-sensitive uses (i.e., residential properties) during pre-curfew hours. An analysis of potential light trespass impacts during post-curfew hours is not necessary because all lighting elements would be extinguished prior to 11:00pm. Potential Impacts to Housing Block A As previously shown on Figure 7, Housing Block A includes residences located northwest of the football field, west of Chatsworth Boulevard and east of Voltaire Street. Google Earth was used to measure the elevation of the residences in Housing Block A. These residences have an average elevation that is approximately 30 feet below that of the football field. As such, vertical and horizontal illuminance measurements from the scenario in which the surrounding areas are 30 feet below the football field were used to analyze the light trespass impacts to homes in this Housing Block. As depicted on Figure 9, Housing Block A Vertical Foot-Candles (30 Below), lighting intensity at the homes within Housing Block A would not exceed 0.0 vertical foot-candles during pre-curfew hours, as calculated at the structures within Housing Block A. The 2014 LIS determined that spill light at Housing Block A would range between vertical foot-candles under pre-curfew conditions. Therefore, the light standards proposed by the Project would reduce the maximum intensity of spill light on Housing Block A as compared to what was estimated in the 2014 LIS. Additionally, and as depicted on Figure 9, no properties west of Chatsworth Boulevard would be exposed to lighting levels exceeding 0.8 vertical footcandles during pre-curfew hours. Accordingly, lighting impacts to homes located within Housing Block A northwest of Chatsworth Boulevard would be less than significant as measured on the vertical plane during pre-curfew hours. Figure 10, Housing Block A - Horizontal Foot-Candles (30' Below), depicts the potential horizontal illuminance created by the Project during pre-curfew hours, as calculated at structures within Housing Block A. As shown, lighting intensity at the homes within Housing Block A would not exceed 0.0 horizontal footcandles, which is consistent with the horizontal illuminance disclosed in the 2014 LIS (0.0 horizontal footcandles). Additionally, and as depicted on Figure 10, no residences northwest of Chatsworth Boulevard

13 ADDENDUM TO POINT LOMA LIGHTING IMPACT STUDY December 18, 2015 Page 12 of 17 would be exposed to lighting levels exceeding 0.8 horizontal foot-candles during pre-curfew hours. Accordingly, lighting impacts to homes located northwest of Chatsworth Boulevard would be less than significant as measured on the horizontal plane during pre-curfew hours. Potential Impacts to Housing Block B As previously shown on Figure 7, Housing Block B encompasses several residential structures located at the northeast corner of Voltaire Street and Chatsworth Boulevard. Google Earth was used to measure the elevation of the residences in Housing Block B. The elevation of the residence closest to the Point Loma High School football field is approximately 32 feet below that of the football field, measured at the point of the structure closest to the field. As such, vertical and horizontal illuminance measurements from the scenario in which the surrounding areas are 30 feet below the football field were used to analyze the light trespass impacts to homes in this Housing Block. In addition, mature landscaping (i.e., trees) exists between the residences in Housing Block B closest to Point Loma High School and the football field, which would serve to reduce illumination affecting these structures, although no reductions from vegetation have been considered in the analysis. As depicted on Figure 11, Housing Block B - Vertical Foot-Candles (30' Below), lighting intensity at the homes within Housing Block B would not exceed 0.0 vertical foot-candles during pre-curfew hours, as calculated at the residential structures within Housing Block B. The 2014 LIS determined that spill light at Housing Block B would range between vertical foot-candles under pre-curfew conditions. Therefore, the light standards proposed by the Project would reduce the maximum intensity of spill light on Housing Block B as compared to what was estimated in the 2014 LIS. Additionally, and as depicted on Figure 11, no properties within Housing Block B would be exposed to lighting levels exceeding 0.8 vertical foot-candles during pre-curfew hours. Accordingly, lighting impacts to homes located within Housing Block B would be less than significant as measured on the vertical plane during pre-curfew hours. Figure 12, Housing Block B - Horizontal Foot-Candles (30' Below), depicts the potential horizontal illuminance created by the Project during pre-curfew hours, as calculated at the residential structures within Housing Block B. As shown, lighting intensity at the homes within Housing Block B would not exceed 0.0 horizontal foot-candles, which represents reduced lighting intensity within Housing Block B as compared to the horizontal illuminance disclosed in the 2014 LIS ( horizontal foot-candles). Additionally, and as depicted on Figure 12, no residences within Housing Block B would be exposed to lighting levels exceeding 0.8 horizontal foot-candles during pre-curfew hours. Accordingly, lighting impacts to homes located within Housing Block B would be less than significant as measured on the horizontal plane during pre-curfew hours. Potential Impacts to Housing Block C Housing Block C encompasses five existing single family homes, located north of Voltaire Street near its intersection with Udall Street, and immediately behind the home team bleachers at the football field. Google Earth was used to measure the elevation of the residences in Housing Block C. The elevations of these residences are approximately 4 to 10 feet below that of the football field. As such, vertical and horizontal illuminance measurements from the scenario in which the surrounding areas are 10 feet below the football field were used to analyze the light trespass impacts to homes in this Housing Block. In addition, the Project s lighting engineer (Musco) noted that the bleachers located on the south side of the football field

14 ADDENDUM TO POINT LOMA LIGHTING IMPACT STUDY December 18, 2015 Page 13 of 17 would serve to substantially reduce illuminance in areas behind the bleachers. Accordingly, Musco accounted for the bleachers as part of their photometric analysis. As depicted on Figure 13, Housing Block C - Vertical Foot-Candles (10' Below), the light standards potentially contribute approximately vertical foot-candles off-site during pre-curfew hours, as calculated at the homes within Housing Block C. Additionally, and as depicted on Figure 13, no structures within Housing Block C would be exposed to lighting levels exceeding 0.8 vertical foot-candles during precurfew hours. Accordingly, lighting impacts to homes located within Housing Block C would be less than significant as measured on the vertical plane during pre-curfew hours. Moreover, the 2014 LIS determined that spill light at Housing Block C north of Voltaire Street would range between vertical foot-candles under pre-curfew conditions. Therefore, the light standards proposed by the Project would reduce the maximum intensity of spill light on Housing Block C as compared to what was estimated in the 2014 LIS, and the significant unavoidable impacts to Housing Block C that were identified in the 2014 LIS would be avoided. Figure 14, Housing Block C - Horizontal Foot-Candles (10' Below), depicts the potential horizontal illuminance created by the Project during pre-curfew hours, as calculated at the residential structures within Housing Block C. As depicted on Figure 14, the light standards would create spill light with a horizontal illuminance between horizontal foot-candles at the residential structures, and no residential structures within Housing Block C would be exposed to lighting levels exceeding 0.8 horizontal foot-candles during pre-curfew hours. Accordingly, lighting impacts to homes located in Housing Block C would be less than significant as measured on the horizontal plane during pre-curfew hours. Furthermore, the 2014 LIS, disclosed lighting levels that ranged from horizontal foot-candles at the homes within Housing Block C. Therefore, the light standards proposed by the Project would reduce the maximum intensity of spill light on Housing Block C as compared to what was estimated in the 2014 LIS, and the significant unavoidable impacts to Housing Block C that were identified in the 2014 LIS would be avoided. Potential Impacts to Housing Block D Housing Block D encompasses two existing homes located just east of the existing entrance into the football stadium from Voltaire Street. Google Earth was used to measure the elevation of the residences in Housing Block D. These residences have elevations that are approximately 2 and 8 feet above that of the football field. As such, vertical and horizontal illuminance measurements from the scenario in which the surrounding areas are at level with the football field were used to analyze the light trespass impacts to homes in this Housing Block. As noted in Table 2, any measurement greater than 0.8 foot-candles is considered significant, for precurfew hours. Figure 15, Housing Block D - Vertical Foot-Candles (Field Level), depicts projected levels of vertical spill light from the proposed football field lighting elements within Housing Block D. The nearest proposed light standard is identified as F3 on Figure 1, which occurs at a distance of approximately 60 feet from the nearest residence in Housing Block D. As such, most of the light trespass which would affect the residences within Housing Block D would be created from light standard F3. As discussed, light intensity is reduced greatly as the distance from a light source increases. As one approaches the residences in Housing Block D, and the distance from the proposed lighting standards increases, lighting intensity would decrease at a rate of approximately 75% for each doubling of distance. Additionally, when two lighting sources are combined, the

15 ADDENDUM TO POINT LOMA LIGHTING IMPACT STUDY December 18, 2015 Page 14 of 17 resulting illuminance only significantly increases if the individual lighting sources have similar lighting intensity at the point of observation when viewed individually. As shown in Figure 15, although portions of the residential lot located at 3530 Voltaire Street within Housing Block D would be exposed to lighting levels up to 1.3 vertical foot-candles, only the garage associated with the residence would be exposed to such lighting levels. As shown on Figure 15, the existing residential structure would be exposed to up to 0.2 vertical foot-candles. Because the primary impact associated with light trespass affecting residential properties is due to sleep deprivation, and because no bedrooms are presumed to occur in the garage, light trespass impacts within Housing Block D would be less than significant. The 2014 LIS determined that spill light to 3530 & 3522 Voltaire Street within Housing Block D north of Voltaire Street would be exposed to lighting levels exceeding 0.8 vertical foot-candles under precurfew conditions. Therefore, the light standards proposed by the Project would reduce the maximum intensity of spill light on Housing Block D north of Voltaire Street as compared to what was estimated in the 2014 LIS, and would eliminate the significant unavoidable impacts identified by the 2014 LIS. Figure 16, Housing Block D - Horizontal Foot-Candles (Field Level), depicts the potential horizontal illuminance created by the Project during pre-curfew hours, as calculated at the residential structures within Housing Block D. As shown, the properties located in Housing Block D would be exposed to Project-related lighting levels up to approximately 1.1 horizontal foot-candles. However, and as shown on Figure 16, neither of the residential structures would be exposed to illumination levels exceeding 0.8 horizontal foot-candles; the highest illumination value affecting these residences would be approximately 0.1 horizontal foot-candles at the residence at 3530 Voltaire Street. Because the primary impact associated with light trespass affecting residential properties is due to sleep deprivation, and because no bedrooms occur in the garage, light trespass impacts within Housing Block D would be less than significant. Thus, the proposed revised light standard improvements for the Project site are reduced on Housing Block D as compared to what was estimated in the 2014 LIS, which identified significant and unavoidable impacts to both residences within Housing Block D. Potential Impacts to Housing Block E Hosing Block E encompasses three single-family homes located on the northwest corner of Voltaire Street at Clove Street. Google Earth was used to measure the elevation of the residences in Housing Block E. These residences have elevations that are approximately 13 to 15 feet above that of the football field. As such, vertical and horizontal illuminance measurements from the scenario in which the surrounding areas are 10 feet above with the football field were used to analyze the worst-case light trespass impacts to homes in this Housing Block. As noted in Table 2, any measurement greater than 0.8 foot-candles is considered significant for pre-curfew hours. As depicted on Figure 17, Housing Block E - Vertical Foot-Candles (10' Above), lighting intensity at the homes within Housing Block E would not exceed 0.0 vertical foot-candles during pre-curfew hours, as calculated at the residential structures within Housing Block E. As such, Project-related lighting impacts to Housing Block E would not occur. The 2014 LIS determined that spill light at one of the residences within Housing Block E (2228 Clove Street) would be exposed to lighting levels exceeding the threshold of 0.8 vertical foot-candles under pre-curfew conditions. Therefore, the revised light standards proposed by the Project would avoid the significant and unavoidable impact to the residence at 2228 Clove Street that was identified in the 2014 LIS.

16 ADDENDUM TO POINT LOMA LIGHTING IMPACT STUDY December 18, 2015 Page 15 of 17 Figure 18, Housing Block E - Horizontal Foot-Candles (10' Above), depicts the potential horizontal illuminance created by the Project during pre-curfew hours, as calculated at the residential structures within Housing Block E. As shown, lighting intensity at the homes within Housing Block E would not exceed 0.0 horizontal foot-candles, which is a reduced impact compared with the horizontal illuminance disclosed in the 2014 LIS, which disclosed that the residence at 2228 Clove Street would be exposed to lighting levels exceeding 0.8 horizontal foot-candles. Thus, the revised light standard proposed by the Project would result in less-than-significant impacts to residences within Housing Block E, and impacts would be avoided as compared to the significant and unavoidable impact that was disclosed in the 2014 LIS. Potential Impacts to Housing Block F Hosing Block F encompasses six single-family homes located to the east of Clove Street. Google Earth was used to measure the elevation of the residences in Housing Block F. These residences have elevations that are approximately 0 to 22 feet above that of the football field. As such, and because illuminance at surrounding properties would decrease with increased elevation in relation to the football field, vertical and horizontal illuminance measurements from the scenario in which the surrounding areas are at level with the football field were used to analyze the worst-case light trespass impacts to homes in this Housing Block. As noted in Table 2, any measurement greater than 0.8 foot-candles is considered significant for pre-curfew hours. As depicted on Figure 17, Housing Block E - Vertical Foot-Candles (10' Above), lighting intensity at the homes within Housing Block F would not exceed 0.0 vertical foot-candles during pre-curfew hours, as calculated at the residential structures within Housing Block F. The 2014 LIS determined that spill light within Housing Block F would range between 0.1 to 0.3 vertical foot-candles under pre-curfew conditions. Therefore, the revised light standards proposed by the Project would reduce the maximum intensity of spill light on Housing Block F as compared to what was estimated in the 2014 LIS, and impacts would result in less-than-significant impacts. Figure 18, Housing Block E - Horizontal Foot-Candles (10' Above), depicts the potential horizontal illuminance created by the Project during pre-curfew hours, as calculated at the residential structures within Housing Block F. As shown, lighting intensity at the homes within Housing Block F would not exceed 0.0 horizontal foot-candles, which represents reduced lighting intensity within Housing Block F as compared to the horizontal illuminance disclosed in the 2014 LIS ( horizontal foot-candles). Additionally, and as depicted on Figure 12, no residences within Housing Block F would be exposed to lighting levels exceeding 0.8 horizontal foot-candles during pre-curfew hours. Accordingly, lighting impacts to homes located within Housing Block F would be less than significant as measured on the horizontal plane during pre-curfew hours. Potential Impacts to Housing Block G Hosing Block G encompasses two single-family homes located at the southwest corner of Clove Street and Xenophon Street. Google Earth was used to measure the elevation of the residences in Housing Block G. These residences have elevations that are approximately 20 feet above that of the football field. As such, vertical and horizontal illuminance measurements from the scenario in which the surrounding areas are 20 feet above the football field were used to analyze the worst-case light trespass impacts to homes in this

17 ADDENDUM TO POINT LOMA LIGHTING IMPACT STUDY December 18, 2015 Page 16 of 17 Housing Block. As noted in Table 2, any measurement greater than 0.8 foot-candles is considered significant for pre-curfew hours. As depicted on Figure 17, Housing Block E - Vertical Foot-Candles (10' Above), lighting intensity at the homes within Housing Block G would not exceed 0.0 vertical foot-candles during pre-curfew hours, as calculated at the residential structures within Housing Block G. The 2014 LIS determined that spill light at one of the residences within Housing Block G (3515 Xenophon Street) would be exposed to lighting levels exceeding the threshold of 0.8 vertical foot-candles under pre-curfew conditions. Therefore, the revised light standards proposed by the Project would avoid the significant unavoidable lighting trespass impacts that were disclosed in the 2014 LIS, and impacts would be less than significant. Figure 18, Housing Block E - Horizontal Foot-Candles (10' Above), depicts the potential horizontal illuminance created by the Project during pre-curfew hours, as calculated at the residential structures within Housing Block G. As shown, lighting intensity at the homes within Housing Block G would not exceed 0.0 horizontal foot-candles, which is a reduced impact compared to the 2014 LIS, which disclosed that the residence at 3515 Xenophon Street would be exposed to lighting levels exceeding 0.8 horizontal foot-candles. Thus, the revised light standard proposed by the Project would result in less-than-significant impacts to residences within Housing Block E, and the significant and unavoidable impact to Housing Block E that was disclosed in the 2014 LIS would be avoided.

18 Conclusion ADDENDUM TO POINT LOMA LIGHTING IMPACT STUDY December 18, 2015 Page 17 of 17 As demonstrated by the foregoing analysis, the modifications to lighting standards and the lighting elements at the Point Loma High School (i.e., relocating and lowering the height of the lighting elements and altering the types of luminaires) did not result in any new environmental impact that was not previously disclosed in the 2014 LIS, although the less-than-significant sky glow impacts that were disclosed in the 2014 LIS would increase under the Project, these impacts are not be considered to be significant due to the relatively low contribution of lighting, background light pollution, and distance from astronomical observation facilities. However, the new improvements to the lighting system is less impactful than the original design, as it generates less spill light as measured from nearby light sensitive areas (i.e., nearby Housing Blocks). The new lighting system, which relocates and lowers each element, does not exceed the significance thresholds for potential impacts to sky glow, glare or light trespass; therefore, impacts are concluded to be less than significant and no mitigation is required.
