CALIFORNIA 92024 T 760 942.5147 F 760.632 0164 From: Stephanie Holly, Chief Finan cial and Operations Officer, Pacific Ridge School Josh Saunders, Dudek Subject: Date: cc: Attachment(s}: Lighting Analysis for the Pacific Ridge School Field Lighting Project September 5, 2019 Bill Hofman, Hofman Planning and Engineering Figures 1-8 SEP O ~ 2019 This memorandum present Dudek's assessment of existing lighting on the Pacific Ridge School campus and analysis of lighting levels generated by proposed field lights to be installed on the Pacific Ridge School soccer/lacrosse field. In addition, potential light and glare impacts associated with the operation of proposed field lighting are evaluated against applicable and relevant thresholds of significance. For example, Pacific Ridge School is located at 6269 El Fuerte in the City of Carlsbad, California, and the City of Carlsbad Planning Division is the lead agency tasked with environmental review of the Pacific Ridge School Field Lighting Project (Project). For thresholds of significance purposes, the City of Carlsbad Planning Division defers to Appendix G of the California Environmental Quality Act (CEQA) Statute and Guidelines, which state that a significant adverse impact would occur if a project would create a new source of substantial light or glare that adversely affect daytime or nighttime views in the area. However, as the Appendix G threshold related to light and glare does not define "substantial," and does not establish a specific, quantifiable lighting level threshold, the County of San Diego (County) significance thresholds for dark skies and glare are relied upon in this memorandum. According to the County significance thresholds for dark skies and glare (County of San Diego 2009), a significant impact would occur if: • The project will install outdoor light fixtures that do not conform to the lamp type and shielding requirements described in Section 59.105 (Requirements for Lamp Source and Shielding) and are not otherwise exempted pursuant Section 59.108 or Section 59.109 of the San Diego County Light Pollution Code. • The project will operate Class I or Class Ill outdoor lighting between 11:00 p.m. and sunrise that is not otherwise exempted pursuant Section 59.108 or Section 59.109 of the San Diego County Light Pollution Code. • The project will generate light trespass that exceeds 0.2 foot-candles measured 5 feet onto the adjacent property. • The project does not conform to applicable Federal, State, or local statutes or regulations related to dark skies or glare, including but not limited to the San Diego County Light Pollution Code. 1 Project Location and Setting The Project is located on the Pacific Ridge School campus at 6269 El Fuerte, Carlsbad, California. Specifically, the Project site encompasses the school's soccer and lacrosse artificial-turf field, which is located at the southern end DUDEK 1 11387 September 2019 ) Memorandum Subject: Lighting Analysis for the Pacific Ridge School Field Lighting Project of the campus (see Figure 1, Location Map). Four 350-foot-long all-weather track lanes are installed to the immediate west of the field, and a small single-story storage shed and permanent bleachers (approximately 25 feet high at the, top level protection fencing) are located nearby to the west. A small rectangular scoreboard supported by two vertical beams is installed near the field's southern goal. Tall fencing/netting installed along the southeastern and southern boundary of the field limits occurrences of soccer and lacrosse balls exiting the field area. While two overhead path lights supported by tall painted poles are installed near the small turf area to the immediate east of the field, no field lights are currently installed. The field is bordered by the school gymnasium facility (approximately 30 to 35 feet high) to the north and landscaped and undeveloped hillside to the west. While the lower portion of the hillside adjacent to the school gymnasium has been noticeably thinned and is landscaped with ornamental shrubs and trees, the larger, undeveloped portion (including the area west of the bleachers) is covered with dry grasses, clusters of cacti, and greyish to dark green coastal sage scrub shrubs. The hillside is relatively steep (the soccer and lacrosse field is located at an elevation of approximately 240 feet above mean sea level [AMSL], and the top of the hillside is situated at approximately 400 feet AMSL), and the flatter, mesa landforms atop the hillsides nearest to the school are developed with one-and two-story single-family residences. A small turf area, landscaped slope, and paved campus driveway and parking spaces are located to .the east of the soccer and lacrosse field. El Fuerte is located approximately 175 feet to the east and is approximately 30 feet lower in elevation than the soccer and lacrosse field. East of the roadway, the local terrain rises and encompasses steep, undeveloped hillsides covered with dry grasses and clustered, greyish to dark green coastal sage scrub shrubs. A narrow dirt path (El Fuerte Wilderness Path) is located near the base of hillside and generally follows the north-south alignment of El Fuerte between Poinsettia Lane and Gateway Road. A small turf area and landscaped slope border the field to the south. The terrain decreases in elevation to the south of the field, and the toe of the landscaped slope abuts a sidewalk and unstriped neighborhood road (i.e., Palmetto Drive) that is lined with single-family residences. The closest residential properties are located within approximately 135 feet of the soccer and lacrosse field and are situated approximately 15 to 25 feet lower in elevation. 2 Project Description Pacific Ridge School intends to install four field light poles on its existing soccer/lacrosse field._Three of the field light poles would be 70 feet high, and one light pole would be 80 feet high. Regarding location, two light poles would be installed to the west of the existing soccer/lacrosse field, and two light poles would be installed to the east. Seven lighting fixtures/bulbs would be installed on each light pole, and all fixtures would be hooded and directed downward onto the playing field surface. The field lighting would be installed to allow for Pacific Ridge School lacrosse and soccer program practices and games to be held on campus in the evenings. Typically, attendance at lacrosse and socc~r program practices and games ranges from 15 to 250, with a typical average of under 50 people. The Project does not include the expansion of existing bleachers or the installation of a public address (PA) system. Timeframes of lighting operations would be regulated by the City of Carlsbad via the required Conditional Use Permit (CUP) and Conditions of Approval. As indicated in the CUP Finding, lighting would be operational throughout the year for a maximum of six months from November to May. During these months, lighting would be used five days week between Monday and Friday, and lighting would not be used on Saturdays or Sundays. During the week (i.e., Monday through Friday), lights would normally operate until 8:00 p.m. However, eight Friday night home games would be scheduled between November and May. On these eight specified Friday nights, lights would operate until 10:00 p.m. DUDEK 2 11387 September 2019 Memorandum Subject: Lighting Analysis for the Pacific Ridge School Field Lighting Project 3 Existing Lighting Sources on Campus On September 11, 2018, Dudek conducted a site visit at Pacific Ridge School to observe and document existing sources of outdoor lighting on campus. The site. visit consisted of observations and docun:,entation only (existing nighttime lighting levels were not calculated). Initially escorted by school staff, Dudek was then permitted to walk the campus unaccompanied to document existing lighting fixtures currently installed in outdoor spaces and on the exterior of buildings. Based on site visit observations, the following primary lighting sources are installed on the Pacific Ridge School campus and along with off-site sources (i.e., streetlights and signals, and exterior and interior lighting fixtures associated with residential development) contribute to the nighttime lighting environment in the Project area. Figure 2, Existing on Campus Lighting Sources, illustrates the lighting sources currently operating on the Pacific Ridge Campus. Parking Lot Lighting. In addition to the small visitor parking lot constructed near the Pacific Ridge/El Fuerte intersection, asphalt-paved parking areas are located in the northern and easternmost areas of campus. Three rectangular lots surfaced with peryious pavement are also located on the campus, north of the gymnasium and south of the administration building. Typical lighting installed in parking lots and driveways consist of dual or single, circular and downward-casting overhead fixtures supported by tall, tubular poles and concrete pedestal bases. While less common, lighting fixtures topped with a circular reflector panel and supported by a tall, tubular pole and concrete pedestal base are also installed in parking lots. Outdoor Seating/Assembly and Open Space Lighting. Outdoor seating/assembly and turf open space areas are concentrated in the center of campus and are generally bordered by parking lots (or classroom buildings) to the east and classroom buildings to the west. Typical lighting sources in these areas consist of lighting fixtures topped with a circular reflector panel and supported by a tall, tubular pole and concrete pedestal. Building Exterior Lighting. Exterior-mounted lighting on campus buildings is commonplace and helps students, parents, and staff navigate the campus during evening and nighttime hours. Observed fixtures on more recently constructed buildings include downward-casting "box" lighting, and "trapezoidal prism" shaped, hooded and downward-casting lighting. Exterior-mounted lighting on the single-story, modular building located in the northeast corner of campus appears aged and includes circular "disk" lighting and plastic domed wall packs. Building Overhang Lighting. Lighting is installed in the underside of building roof structures covering outdoor seating areas and covered; ground floor areas near building entrances. These lighting fixtures consist of surface- mounted, white cylinder down lights. With the exception of some wall packs (lights) that are on photo cells and other exterior-mounted building lighting operated with timers, exterior lighting on the Pacific Ridge School campus operates (i.e., is on) from dusk to dawn. DUDEK 3 11387 September 2019 Memorandum Subject: Lighting Analysis for the Pacific Ridge School Field Lighting Project 4 Regulatory Setting State Cslifomia Environmental Quality Act Appendix G of the CEQA Statutes and Guidelines establishes sample questions/thresholds that may be used by jurisdictions to determine the severity of impacts, including impacts to existing views and visual character. Regarding impacts associated with lighting sources, Appendix G states that a significant impact would occur if a project would create a new source of substantial light or glare that adversely affects day-or nighttime views in the area. Local City of carlsbad Municipal Code According to the City of Carlsbad Zoning Map (City of Carlsbad 2017), the Pacific Ridge School campus is located a large area located east of El Camino Real and south of Palomar Airport Road zoned P-C (Planned Community). Pursuant to Section 21.38.020 of the City's Municipal Code, "the permitted uses and structures [in the Planned Community Zone] shall be established by a master plan of development." In addition, Section 21.38.040 establishes that the City Council must approve a master plan of development prior to the approval for any permits for deYelopment on property zoned P-C (City of Carlsbad 1976). As permitted uses and structures in the P-C zone are established by the master plan of development, the P-C zone does not include specific development standards for lighting. carlsbad Habitat Management Plan The Carlsbad Habitat Management Plan for Natural Communities (Carlsbad HMP) (City of Carlsbad 1999) is a comprehensive, Citywide, program to identify how the City, in cooperation with federal and state wildlife agencies, intends to preserve the diversity of habitat and protect sensitive biological resources within the City while allowing for additional development consistent with the City's General Plan and its Growth Management Plan. In addition to developing and describing the Citywide conservation strategy and local implementation process, preserve management policies are established and include adjacency standards. The fencing, signs, and lighting standards are relevant to this lighting analysis and according to the Carlsbad HMP, "night lighting impacts habitat value of the preserve, particularly for nocturnal species" (City of Carlsbad 1999). Further, the Carlsbad HMP includes the following management recommendations related to lighting: ( • Eliminate lighting in or adjacent to the preserve except where essential for roadway, facility use, and safety and security purposes; • Use low pressure sodium illumination sources. Do not use low voltage outdoor or trail lighting, spot lights, or bug lights. Shield light sources adjacent to the preserve so that the lighting is focused downward; and • Avoid excessive lighting in developments adjacent to linkages through appropriate placement and shielding of light sources. DUDEK 4 11387 September 2019 Memorandum Subject: Lighting Analysis for the Pacific Ridge School Field Lighting Project County of San Diego Outdoor Ught Pollution Code The County establishes regulations pertaining to the minimization of light poHution and preservation of dark skies in Title 5, Chapter 2, Light Pollution, in the County of San Diego Code of Regulatory Ordinances (County of San Diego Code of Regulatory Ordinances Sections 51.201-51.209; County of San Diego 2012). County Code Sections 51.201 through 51.209 are also collectively referred to as the Light Pollution Code. The regulations of the Light Pollution Code only apply to land uses and properties within the unincorporated portions of the County; therefore, they are not requirements for the Project. However, in consideration of potential regional influences of lighting effects, these regulations are presented in this analysis and provide guidance for·the analysis of potential impacts to dark skies. Specifically, Palomar Mountain and Mount Laguna observatories have been identified by the County as valuable resources that should be protectE;id from the effects of light pollution. Lamp type and shielding requirements for outdoor lighting fixtures are provided in the County's Light Pollution Code for the preservation of dark skies surrounding these resources within a 15-mile radius (Zone A) or outside of a 15-mile radius of observatories (Zone 8). Pacific Ridge School is located approximately 30 miles from the Palomar Mountain Observato_ry and 50 miles from the Mount Laguna Observatory, and is, thus, located in Zone B. Further, the Light Pollution Code differentiates outdoor lighting by primary use, and organizes lighting in one of three classes. Class I lighting consists of outdoor lighting for outdoor sales or eating areas or recreation facilities, and Class II lighting includes outdoor lighting for walkways, roadways, and parking lots. Class Ill lighting consist of outdoor lighting for decorative effects. Proposed field lighting at Pacific Ridge School would be considered Class I lighting. In accordance with Light Pollution Code Section 51.204, all Class I lighting in Zone B must be fully shielded. Also, pursuant to Section 51.206(a) (4), Hours of Operation, Cl.ass I lighting must be turned off between 11:00 p.m. and sunrise, with the exception that lighting at an outdoor recreational facility may remain on to allow an organized recreational event in progress to be completed, provided the event and the facility are not violating the terms of any permit issued by the County or any law or regulation. County of San Diego Thresholds for Determining Significance and Report Format and Content Requirements:. Dark Skies and Glare According to the County of San Diego, "nighttime light that spills outside its intended area and lighted signs can be annoying to neighbors and potentially harmful to motorists, cyclists, and pedestrians" (County of San Diego 2009). The significance thresholds listed in the introduction to this memorandum and in Section 5, Analysis, below, are used to determine evaluation of whether a significant impact to dark skies or from glare will occur as a result of Project implementation. Specifically, Threshold 3 .includes a quantified threshold intended to reduce impacts on dark skies and reduce or eliminate light trespass into neighbor's yards and windows and/or into adjacent habitats. 5 Impact Analysis -Aesthetics Methodology Although the County is neither the lead agency nor a responsible agency for the Project, the County of San Diego Gu.idelines for Determining Significance for Dark Skies and Glare (County of San Diego 2009) were reviewed, in addition to CEQA Guidelines Appendix G, to develop appropriate significance thresholds for the Project. The City of DUDEK 5 11387 September 2019 Memorandum Subject: Lighting Analysis for the Pacific Ridge School Field Lighting Project Carlsbad typically relies on aesthetics thresholds contained within CEQA Guidelines Appendix G when assessing the potential environmental impacts of development proposals. However, as the Appendix G threshold related to light and glare does not define "substantial" and does not establish a specific, quantifiable lighting level threshold, the County significance thresholds for dark skies and glare are relied upon in this memorandum to determine the severity of lighting and glare generated by the Project. The following County significance thresholds are used to evaluate whether a significant lighting impact would occur as a result of the Project: • The project will install outdoor light fixtures that do not conform to the lamp type and shielding requirements described in Section 59.105 (Requirements for Lamp Source and Shielding) and are not otherwise exempted pursuant Section 59.108 or Section 59.109 of the San Diego County Light Pollution Code. • The project will operate Class I or Class Ill outdoor lighting between 11:00 p.m. and sunrise that is not otherwise exempted pursuant Section 59.108 or Section 59.109 of the San Diego County Light Pollution Code. • The project will generate light trespass that exceeds 0.2 foot-candles measured 5 feet onto the adjacent property. • The project does not conform to applicable Federal, State, or local statutes or regulations related to dark skies or glare, including but not limited to the San Diego County Light Pollution Code. To determine identify lighting levels and lighting spillover created by operation of the Project, an illumination study was prepared by Musco Lighting (Musco Lighting 2018). Musco Lighting (Musco) specializes in the design and manufacturer of sports and large area lighting systems. The illumination study includes a summary of the characteristics (height, fixture quantity, lum inaire type) of the proposed lighting system at Pacific Ridge School. An off-field maintained horizontal foot-candles illumination summary is also included in the study and illustrates the calculated spill light levels generated by proposed field lighting at nearby off-field location and at and beyond the campus property line. Analysis Threshold 1: Would the project install outdoor light fixtures that do not conform to the lamp type and shielding requirements described in Section 59.105 (Requirements for Lamp Source and Shielding) and are not _otherwise exempted pursuant Section 59.108 or Section 59.109 of the San Diego County LightPollution Code? Analysis: New athletic field lighting installed at Pacific Ridge School would be considered a Class I lighting source according to the categories defined by Section 51.203 of the County Light Pollution Code. According to the Light Pollution Code, all Class I lighting located greater than 15 miles from the Palomar Mountain and Mount Laguna Observatories (i.e., lighting sources located i.n Zone B) must be fully shielded. There are no other lamp type and shielding requirements for Class I lighting in Zone B. Proposed field lighting at Pacific Ridge School would comply with the applicable lamp source and shielding requirements for Class I lighting in Zone B. As proposed, mounted luminaire assemblies containing seven fixtures each of Musco's LED-TLC 900 luminariE:)S would be installed on four tubular steel poles. Poles located to the west of the field would be 70 feet high, and poles located east of the field would be 70 and 80 feet high (the 80-foot- high pole would installed near the southeastern corner of the field). All mounted lighting assemblies would be hooded and fully shielded to avoid unnecessary illumination of the night sky during evening practices and games DUDEK 6 11387 September 2019 Memorandum Subject: Lighting Analysis for the Pacific Ridge School Field Lighting Project • and to minimize off-campu~ light trespass and glare. As such, the Project would comply with the lamp type and shielding requirements of the Light Pollution Code, and impacts would be less than significant. Threshold 2: Would the project will operate Class I or Class Ill outdoor lighting between 11:00 p.m. and sunrise • that is not otherwise exempted pursuant Section 59.108 or Section 59.109 of the San Diego County Light Pollution Code? Analysis: As described in Section 2, Project Description, above, the timeframes of field lighting operations wot,Jld ultimately be regulated by the City of Carlsbad via the required CUP and Conditions of Approval. As proposed by Pacific Ridge School, new field lighting would be operational throughout the year for a maximum of six months from November to May. During these months, lighting would be used five days a week between Monday and Friday only and would normally· operate until 8:00 p.m. However, eight Friday night home games would be scheduled between November and May, and during these games field lights would operate until 10:00 p.m. Therefore, consistent with thresholds regulating the operations of Class I lighting, the Project would not operate field lights between 11:00 p.m. and sunrise. The Project would comply with operational timeframes for lighting established in the Light Pollution Code, and impacts would be less than significant. Threshold 3: Would the project generate light trespass that exceeds 0.2 foot-candles measured 5 feet onto the adjacent property? Analysis: Some level of naturally occurring nighttime illuminance is usually observable and experienced. For instance, the typical illuminanee from moonlight is 0.03 foot-candles, and coupled with artificial lighting, nighttime illuminance is typically-higher than the naturally occurring prevalent level,. especially in urban and suburban areas (County of San Diego 2009). Musco prepared an illumination study for the Project to determine the spill lighting levels and characteristics of proposed field lighting at Pacific Ridge School. Consistent with the characterization of proposed field l_ights included in the Threshold 1 discussion above, the illumination study considered the installation of four tubular steel light poles (i.e., poles Si, S2, S3 [70 feet high each] and S4 [80 feet high]) with mounted luminaire assemblies containing seven fixtures each of Musco's TLC-LED-900 luminaries). The location of proposed field lights is illustrated on Figure 3, Location of Proposed Field Lights. The maintained horizontal foot-candle lighting levels produced by the proposed field lights at the property line of Pacific Ridge School is illustrated on Figure 4, Illumination Summary (1 of 3). As shown on Figure 4, where the school's southern property line borders residential properties off Palmetto Drive, the maintained horizontal foot- candle lighting levels would be 0.0 foot-candles (see Figure 4). Further, lighting levels at more distant residential property lines to the south, southwest and west would also be 0.0 foot-candles (see Figures 5 and 6, Illumination Summary [2 of 3 and 3 of 3]). Lastly, lighting levels at the west and east property line of Pacific Ridge School would be 0.0 foot-candles during operation of proposed field lights (see Figure 4). As lighting levels during operation of the proposed field lights would be 0.0 foot-candles at the south, north, ~ast and west property line of Pacific Ridge School and would be less than that allowed by the threshold (0.2 foot-candles), light trespass irr:ipacts would be less than significant. DUDEK 7 11387 September 2019 Memorandum Subject: • Lighting Analysis for the Pacific Ridge School Field Lighting Project Threshold 4: Would the project not conform to applicable Federal, State, or local statutes or regulations related to dark skies or glare, including but not limited to the San Diego County Light Pollution Code? Analysis: Regulations applicable to the Project are discussed in Section 4, Regulatory Setting. As stated previously in response to Thresholds 1 and 2, proposed field lights would operate in accordance with the relevant sections of the County Light Pollution Code and would be subjeQt to timeframe stipulations and operational conditions developed by the City. Further, as stated previously in response to Threshold 3, light trespass associated with proposed field lighting at Pacific Ridge School would have a less-than-significant impact on the surrounding residential environment where nighttime lighting sources including streetlights, entrance lighting, and interior lighting currently operate. Therefore, the Project would con~orm to regulations related to dark skies, light trespass, and glare; and impacts would be less than significant. 6 Impact Analysis -Lighting Effects on Biological Resources Preserve lands-identified in the Carlsbad HMP occur immediately to the west of the property· boundary of the soccer/lacrosse field at Pacific Ridge School. The Carlsbad HMP states that night lighting impacts habitat value of the preserve, particularly for nocturnal species, and recommends that lighting in adjacent areas be shielded and directed away from the preserve (City of Carlsbad 1999). Therefore, lighting is not permitted in the preserve, • except where essential for roadways, facility use, and safety. Habitat types within the preserve that occur to the west of the soccer/lacrosse field include annual (non- native) grasslands and coastal sage scrub. Annual (non-native) grasslands exist immediately adjacent to the school property line, while coastal sage scrub habitat begins approximately 80 feet further to the west and upslope of the school property line (see Figure 7, Carlsbad HMP Preserve, and Figure 8, Existing Conditions of HMP Preserve Lands). As proposed, all four of the proposed light pole assemblies would be hooded and fully shielded to direct unnecessary lighting away from the adjacent preserve land. Results of the illumination study determined that as proposed, lighting levels of 0.0 foot-candles would be received just beyond the field bleachers, the campus's western property line, and within the HMP preserve (see Figure 4; while not labeled, the HMP preserve is located to the immediate west of the campus's western property line). To clarify, no measurable lighting (i.e., horizontal foot-candles) associated with operation of proposed field lighting is anticipated to be received on adjacent HMP preserve lands during evening lacrosse and soccer games and practices. Because no measurable lighting would trespass from the school property to adjacent HMP preserve lands, the Project would be consistent with the lighting recommendations of the Carlsbad HMP. Thus, lighting effects on biological resources would be less than significant. DUDEK 8 11387 September 2019 ,.
