Los Gatos High School Sports Field Lighting Initial Study Los Gatos-Saratoga Union High School District ii February 2015

SECTION 1.0 INTRODUCTION AND PURPOSE This Initial Study of environmental impacts is being prepared to conform to the requirements of the California Environmental Quality Act (CEQA) and the CEQA Guidelines (California Code of Regulations §15000 et.seq.). This Initial Study evaluates the potential environmental impacts that might reasonably be anticipated to result from replacing the existing sports lighting at the Los Gatos High School softball field, baseball field, and multiuse field located adjacent to the baseball field, and adding sports lighting to the multi-use field adjacent to the softball field. 1.1 Background and Objective Under existing conditions, the Los Gatos High School softball field, baseball field, and multiuse field located adjacent to the baseball field are all equipped with permanent sports lighting. The multi-use field located adjacent to the softball field is not equipped with permanent sports lights; however; portable sports lighting is currently used on the multi-purpose field to allow for evening use. The project is proposed by the Los Gatos-Saratoga Union High School District to provide better, safer sports lighting on the softball, baseball, and multi-use fields. No new lit evening use of the fields are proposed by the project. The existing schedule of lit evening use on the softball, baseball and multi-use fields would continue under the proposed project.

SECTION 3.0 PROJECT DESCRIPTION 3.1 EXISTING AND PROPOSED USE The District proposes to replace the existing permanent sports lighting at the Los Gatos High School (LGHS) softball field, baseball field, and multiuse field located adjacent to the baseball field, and add permanent sports lighting to the multi-use field adjacent to the softball field. The baseball field and adjacent multiuse field are located in the northeast corner of the campus. The softball field and adjacent multi-use field are located on the west side of the campus, between the main campus and SR 17. Existing use of the fields includes the following: Baseball/Multiuse Fields

• Baseball practice and games • Band practice • Soccer, football, and lacrosse practices and games

Softball/Multiuse Fields

• Softball practice and games • Band practice • Soccer, football, lacrosse, and field hockey practices and games

Current use on the baseball, softball and multi-use fields generally occurs during the hours of 8:00 AM through 9:00 PM throughout the week. Portable lights with diesel generators are currently used on the multi-use field adjacent to the softball field. The existing schedule of lit evening field use is shown below in Tables 3.1-1 and 3.1-2.

3.2 SPECTATOR ATTENDANCE Spectator attendance at the existing and proposed uses at the softball, baseball, and multi-use fields varies between 40 and 60 spectators per game. Spectator attendance is not anticipated to increase with the proposed sports lighting, and no increase in bleacher capacity is proposed. The projects do not propose to install public address (PA) systems. 3.3 LIGHTING DESIGN The lighting design would adhere to the recommendations of the Illuminating Engineering Society of North America (IESNA). According to the IESNA, a high school facility with spectator capacity under 5,000 is considered a Class II facility and a facility with some provision for spectators is considered a Class III facility.1 The IESNA recommends an average light level of 50 maintained foot candles for a football field at a Class III facility and 50 maintained footcandles at a Class II facility.2 The proposed lights would provide an average of 50 foot candles in the infields and 30 footcandles in the outfields of the softball and baseball fields. An average of 30 and 25 footcandles are proposed on the multi-use fields adjacent to the softball field and baseball field, respectively.3 The proposed sports lighting on the softball field and adjacent multi-use field includes a total of 10 light standards (poles). The light standards would be 60 feet in height, and each standard would hold three to six metal halide lamps. The location of each light standard on the softball field and adjacent multi-use field is shown on Figure 3.1-1. The proposed sports lighting on the baseball field and adjacent multi-use field includes a total of eight light standards. The standards would range in height from 70 to 90 feet, and each standard would hold six to 12 metal halide lamp fixtures. The location of each standard on the baseball field and adjacent multi-use field is shown on Figure 3.1-2.

1 Illuminating Engineering Society of North America, Recommended Practice for Sports and Recreational Lighting, 2001. 2 “Maintained Footcandles” is the term used to describe the light level that a lamp is expected to provide over the long-term, after there is a loss of light due to dirt accumulation on the reflector and lens, and a loss of lamp output. For comparison, "Initial Footcandles" is the term used for the amount of light measured after only 100 hours of lamp operation and is generally 20% higher than the maintained footcandles. This is the amount of light that can be expected immediately after installation of the proposed lighting. 3 A footcandle (fc) is one lumen of uniform luminance over an area of one square foot.

Each fixture has an aluminum reflector, light hood, and visor to direct light onto the field and reduce the amount of spill light (refer to Section 4.1 Aesthetics).4 The fixtures would be equipped with 1,500-watt metal halide lamps. These proposed high power lamps reduce the number of fixtures needed and increase light beam control and efficiency, thereby reducing the size of the light racks mounted atop of the standards and minimizing the amount of spill light onto the adjacent land uses. Installation of the proposed lighting system would require minor excavation to construct the foundations for the light standards and route the electrical conduit. 1.3.1 Softball and Multi-use Field Reconfiguration In addition to replacing the existing permanent sports lights at the softball field and adding permanent sports lighting to the multi-use field, the project proposes to switch the locations of the softball and multi-use fields; the multi-use field would be moved to the east side of the fields, adjacent to the tennis courts, and the softball field would be moved to the west side of the fields, adjacent to the residences (refer to Figure 3.1-1). The reconfiguration is proposed to better utilize field space and reduce noise levels at the adjacent residences. The noise reduction results because the softball field is only utilized during softball season (January to June), while the multi-use field, which is currently adjacent to residences, is utilized year-round, including band practice. 1.3.2 Emergency Lights Metal halide lamps typically take 10 minutes to come back on after a power outage. In accordance with state requirements, the District will develop an emergency egress lighting plan to ensure the safe exit of spectators from the bleachers, in the event of a power outage. As part of this emergency egress lighting plan, the proposed project includes the installation of battery operated lights on the light standards located near the bleacher and pathways. In the event the field lights go out, these battery powered back-up lights will turn on.

SECTION 4.0 SETTING, ENVIRONMENTAL CHECKLIST AND IMPACTS

This section describes the existing environmental conditions on and near the project site, as well as environmental impacts associated with the proposed project. The environmental checklist, as recommended in the California Environmental Quality Act (CEQA) Guidelines, identifies environmental impacts that could occur if the proposed project is implemented. The right-hand column in the checklist lists the source(s) for the answer to each question. The sources cited are identified at the end of this section. Mitigation measures are identified for all significant project impacts. “Mitigation Measures” are measures that will minimize, avoid, or eliminate a significant impact (CEQA Guidelines §15370). 4.1 AESTHETICS The following discussion is based upon technical information prepared by Musco Lighting. This technical information describes the proposed sports field lighting, including the height of the light standards, the number of fixtures per light standard, and illumination summaries showing the proposed light levels on and off the softball, baseball and adjacent multi-use fields.5 A copy of the technical information is included as Appendix A of this Initial Study. In addition, project photosimulations were professionally prepared, and are included on the following pages. 4.1.1 Setting 4.1.1.1 Visual and Aesthetic Character of the Project Area The Los Gatos High School campus is located in Town of Los Gatos, in an area developed with residences and commercial uses. The topography in the immediate vicinity of Los Gatos High School is relatively flat, sloping gently down from south to north. The softball and multi-use fields are located on the west side of the campus along SR 17, and are at a lower elevation than the remainder of the campus. The baseball and multi-use fields are located in the northeast corner at-grade with the campus. In addition to the softball, baseball, and multi-use fields, the campus includes a track and field stadium, tennis courts, swimming pool, student and faculty parking areas, a gymnasium, theater, and one- and two-story tall classroom and administration buildings. The existing visual character of the area surrounding the Los Gatos High School campus is a residential neighborhood with a commercial district. Homes in the immediate project area include new remodels and older residences constructed beginning in the early to mid-1900s. Newer, two-story condominiums, an office building, and a church back up to the west and south sides of the softball and multi-use fields, and SR 17, a four-lane divided highway, travels along the northwest boundary of the softball and adjacent multi-use fields. Numerous large trees, creating a dense tree canopy, are located between these surrounding uses and the softball and multi-use fields. Several

5 The following analysis and photosimulations focus on the proposed lights at the softball field and adjacent multi-use field, since sports lighting is currently installed on the baseball and adjacent multi-use field under existing conditions and, as a result, the project would not result in a substantial change. Los Gatos High School Sports Field Lighting Initial Study Los Gatos-Saratoga Union High School District 13 February 2015

community buildings owned by the Town of Los Gatos are located within the campus in the wooded area between the softball and multi-use fields and SR 17. The area north of the baseball and multi-use fields is developed with a circa 1970’s hotel complex that includes over 10 acres of landscaped grounds and one- and two-story hotel buildings. The areas east and south of the fields are developed with one- and two-story residences. Large trees forming dense canopies are located immediately south, east, and north of the baseball and multi-use fields. 4.1.1.2 Existing Light Sources Existing light sources at Los Gatos High School include security lighting throughout the campus, parking lot lights, swimming pool lights, tennis court lights, sports field lighting at the football stadium, baseball field and adjacent multi-use field, and softball field, and lights on various campus buildings. Portable sports lighting is currently used at the multi-use field adjacent to the softball field. When the sports lighting at the softball field and/or portable multi-use field sports lighting is not in use, light levels on the softball field and multi-use field are low. Given the unshielded design and projection of the short portable sports lights across the multi-use field, light levels are high when the portable lights are in use. Existing light sources in the project area include streetlights along main roads, vehicle headlights, security lighting, and parking lot lights. Light levels in many of the surrounding neighborhoods are quite dark due to the absence of streetlights and presence of mature tree canopies, however, vehicle lights on SR 17 are a constant source of light in the area. 4.1.1.3 Scenic Vistas and State Scenic Highways While the project site can be seen in the distance from the Santa Cruz Mountains to the south and west, the site is not located within a designated scenic vista or view corridor. The area around the project site is fully developed with residences and commercial uses. A major highway (State Route 17) is located adjacent to the site. The portion of State Route (SR) 9 (Big Basin-Saratoga-Los Gatos Road) between SR 17 and SR 35 is the only officially designated state scenic highway in Santa Clara County, and is located approximately 400 feet north of the project site. Due to the topography, intervening development and trees, there are no views of the campus from SR 9. 4.1.2 Environmental Checklist and Discussion of Impacts

The courts have ruled that under CEQA, “the question is whether a project will affect the environment of persons in general, not whether a project will affect particular persons.”6 This ruling is particularly relevant to the visual, aesthetics, and lighting impacts of the proposed project, because the proposed project would affect the occupants of residences immediately adjacent to the softball, baseball, and multi-use fields to a much greater degree than the surrounding population in general. 4.1.2.1 Proposed Lighting As stated in the project description, the proposed lights are specifically designed for the softball, baseball, and multi-use fields, and the proposed light levels are specifically intended for their use. As recommended by the Illuminating Engineering Society of North America (IESNA), the proposed sports lighting is designed to provide an average light level of 50 and 30 maintained footcandles on the softball and baseball infields and outfields, respectively. The proposed lights would provide an average of 30 and 25 footcandles on the multi-use fields adjacent to the softball and baseball fields, respectively.7 The proposed sports lighting on the softball field and adjacent multi-use field includes a total of 10 light standards (poles). The standards would be 60 feet in height, and each standard would hold three to six metal halide lamps. The location of each light standard on the softball field and adjacent multi-use field is shown on Figure 3.1-1. The proposed sports lighting on the baseball field and adjacent multi-use field includes a total of eight light standards. The standards would range in height from 70 to 90 feet, and each standard would hold six to 12 metal halide lamp fixtures. The location of each standard on the baseball field and adjacent multi-use field is shown on Figure 3.1-2. Each fixture has an aluminum reflector, light hood, and visor to direct light onto the field and reduce the amount of spill light.8 The fixtures would be equipped with 1,500-watt metal halide lamps. These proposed high power lamps reduce the number of fixtures needed and increase light beam control and efficiency, thereby reducing the size of the light racks mounted atop of the standards and minimizing the amount of spill light onto the adjacent land uses. The proposed project would replace the existing permanent sports lighting at the Los Gatos High School softball and baseball fields and the multi-use field adjacent to the baseball field, and install permanent sports lighting at the multi-use field adjacent to the softball field. The proposed sports lighting at the multi-use field adjacent to the softball field would be used in place of the portable sports lighting that is currently used at the field during the proposed time period for the same proposed uses and, therefore, would not increase use of the multi-use field. Identical to the schedule

of lit evening use under existing conditions (refer to Tables 3.1-1 and 3.1-2), the proposed lighting on the softball, baseball, and adjacent multi-use fields would be used Monday through Sunday during the months of August through June. All lit events at the softball, baseball, and multi-use fields would end by 9:00 PM, and the lights would be turned off no later than 9:30 PM (refer to Tables 3.1-3 and 3.1-4). Existing spectator seating capacity at the softball, baseball, and multi-use fields would not be increased and overall spectator attendance is not expected to substantially increase.

Field Reconfiguration In addition to replacing the existing permanent sports lighting at the softball, baseball, and multi-use field adjacent to the baseball field and adding permanent sports lighting to the multi-use field adjacent to the softball field, the project proposes to switch the locations of the softball and multi-use fields. The multi-use field would be moved to the east side of the fields, adjacent to the tennis courts, and the softball field would be moved to the west side of the fields, adjacent to the residences (refer to Figure 3.1-1). The reconfiguration is proposed to better utilize field space, reduce noise levels and improve overall compatibility with the adjacent residences. The noise reduction results because the softball field is only utilized during softball season (January to June), while the multi-use field, which is currently adjacent to residences, is utilized year-round, including band practice. 4.1.2.2 Views of the Proposed Lighting The Los Gatos High School campus is not located on a hill. The project area is relatively flat and developed and vegetated with numerous tall trees. Due to the relatively flat topography in the immediate area of the campus, surrounding development, and numerous tall trees, views of the project site are limited to the immediate area. The softball and adjacent multi-use fields are at a lower elevation and surrounded by development, trees, and SR 17, which limits views of the fields to the immediate vicinity. The proposed lighting on the softball field and adjacent multi-use would be most visible from the condominiums, commercial uses, and church on Church Street that back up to the south and east side of the fields. The proposed lights on the softball, baseball, and multi-use field adjacent to the baseball field would replace existing permanent sports lighting with superior lighting technology that results in less spill light compared to the existing sports lighting. For these reasons, the proposed replacement of existing sports lighting at the softball, baseball, and multi-use field adjacent to the baseball field would not substantially changes views of these fields during the day or evening. The new permanent sports lighting on the multi-use field adjacent to the softball field would be elevated up to 60 feet above the field and, as a result, these new lights and poles would be visible from various vantage points during the day and during the evening, when in use. The lights and poles would be painted a non-reflective color which would reduce glare during the day. The visual change resulting from the new lighting on the multi-use field and replacement lighting on the softball field is illustrated in the photosimulations on the following pages. Existing daytime and evening photographs of the fields from public vantage points were taken by a professional photographer and these photos were then used to prepare photosimulations of the proposed lighting. The photographs were taken from SR 9/SR 17 overcrossing located north of the campus and the pedestrian bridge over SR 17 that is located west of the softball and multi-use fields. The locations from which the photographs were taken are shown on Figure 4.1-1 and the photosimulations are shown on Figures 4.1-2 through 4.1-5.


As depicted in the photosimulations, the existing tall trees in the project area would substantially block views of the proposed sports lighting on the softball and adjacent multi-use fields in the proposed configuration. Although both vantage points are elevated, the trees along SR 17 are taller than the proposed light standards, blocking views of the lights standards. As shown in the photosimulations from SR 9, the view from this designated state scenic highway would not be substantially affected by the project. Existing light sources at Los Gatos High School include security lighting throughout the campus, parking lot lights, swimming pool lights, tennis court lights, sports field lighting at the football stadium, baseball field and adjacent multi-use field, and softball field, and lights on various campus buildings. Portable sports lighting is currently used at the multi-use field adjacent to the softball field. Given these existing light sources on the campus and the existing use of portable sports lighting on the multi-use field, the proposed sports lighting at the softball field and adjacent multi-use field would not substantially change views of the campus. Compared to the unshielded, portable sports lighting currently used on the multi-use field, the proposed sports lighting would create substantially less glare and spill light onto the surrounding residential properties. This is because the existing portable sports lighting is unshielded and the short portable light standards direct the light across the field, rather than down onto the field, unlike the proposed shielded sports lighting that creates less glare and can be focused down onto the field. Consistent with the current use of the permanent and portable sports lights that would be replaced by the project, the proposed lights would be turned off by 9:30 PM. Compared to existing conditions, the use of the softball, baseball, and multi-use fields would not change. For these reasons and those stated above, the proposed project would not be expected to substantially affect nighttime views in the project area or substantially degrade the character of the project site and surrounding area. (Less Than Significant Impact) 4.1.2.3 Spill Light from the Proposed Project The proposed light fixtures would be angled downward and would include light visors and light hoods to direct the light down onto the field and minimize the amount of spill light onto adjacent streets and residences. These same features also restrict a person from seeing the arc tube (the brightest part of the light) from the areas surrounding the playing field. Even with these features, some spill light from the proposed project would result, due to reflection off the playing fields and other surfaces below the lights. The proposed lights on the softball, baseball, and multi-use fields would replace existing sports lighting with superior lighting technology that results in less spill light compared to the existing sports lighting; this is especially true for the replacement of the portable sports lighting. The resulting spill light during operation of the reconfigured softball and multi-use fields was calculated and is shown in Figure 4.1-6. The spill light levels shown on Figure 4.1-6 are conservative, in that they do not take into account any shielding provided by intervening trees. Compared to the unshielded, portable sports lighting currently used on the multi-use field that would be replaced by the project, the proposed sports lighting would create substantially less glare and spill light onto the adjacent residential properties. This is because the existing portable sports lighting is unshielded and must be projected across the field, unlike the proposed shielded sports lighting that can be focused down onto the field and creates less glare. For these reasons, the proposed replacement of the existing permanent sports lighting on the softball, baseball, and multi-use field adjacent to the baseball field and portable, unshielded sports lighting used on the softball/multi-use field with superior, new sports lighting technology would not substantially increase overall light levels in the project area. (Less Than Significant Impact)

4.1.3 Conclusion The project site, an existing high school with numerous light sources, is located in a developed area. Existing sports lighting is currently used on the campus, including tall light standards at the existing football stadium, softball, baseball, and multi-use field adjacent to the baseball field and portable, unshielded sports lighting at the softball/multi-use field. There are also a lit tennis courts and a swimming pool and parking lots on the campus, as well as building and security lights throughout the campus. The existing, unshielded, portable sports lighting currently used on the multi-use field adjacent to the softball field would be replaced by the proposed project, resulting in less glare and spill light. The proposed schedule and use of the softball, baseball, and multi-use fields be identical to existing conditions; the lights would be turned off by 9:30 PM for all events. The proposed sports lighting would be visible from the immediate surrounding area, especially when in use during the evening. From more distant vantage points, the presence of mature tree canopies and location of the fields in relation to surrounding development results in the proposed sports lighting being barely visible. The proposed lighting would not have a substantial adverse effect on a scenic vista and would not be visible from a state scenic highway. The proposed lighting would not substantially affect the visual character or quality of the surrounding area. The project would not create a substantial source of daytime glare. Although individual views from adjacent residences may be affected, sports lighting is currently used on the fields, and, therefore, the use of the proposed lighting would not substantially change nighttime views of the surrounding area. The lighting would be designed to reduce spill light and the visibility of the lights. The proposed use of the lights would be identical to the existing use. For these reasons, the proposed replacement of the existing permanent sports lighting on the softball, baseball, and multi-use field adjacent to the baseball field and replacement of the portable, unshielded sports lighting used on the softball/multi-use field with superior, new sports lighting technology would not result in significant aesthetic impacts. (Less Than Significant Impact)


4.2 AGRICULTURAL AND FOREST RESOURCES 4.2.1 Setting The project site, an existing baseball field and adjacent multi-use field and softball field and adjacent multi-use field, is located on the Los Gatos High School campus in the Town of Los Gatos. According to the Santa Clara County Farmland Map 2014, the project site is designated as Urban and Built-up Land. Urban and Built-up Land is defined as residential land with a density of at least six units per ten acre parcel, as well as land used for industrial and commercial purposes, golf courses, landfills, airports, sewage treatment, and water control structures. The site is not the subject of a Williamson Act contract and there is no agricultural use on or adjacent to the project site. According to California Public Resources Code Section 12220(g), Forest Land is land that can support 10-percent native tree cover of any species, including hardwoods, under natural conditions, and that allows for management of one or more forest resources, including timber, aesthetics, fish and wildlife, biodiversity, water quality, recreation, and other public benefits. According to California Public Resources Code 4526, “Timberland” means land, other than land owned by the federal government and land designated by the board as forest land, which is available for, and capable of growing a crop of trees of any commercial species used to produce lumber and other forest products, including Christmas trees. The project site is not forest land or timberland. 4.2.2 Environmental Checklist and Discussion of Impacts

The proposed project would replace the existing permanent sports lighting at the Los Gatos High School softball and baseball fields and the multi-use field adjacent to the baseball field, and add permanent sports lighting to the multi-use field adjacent to the softball field. The project site is located in a suburban area that is not used for agricultural purposes. The proposed lighting would not affect Prime Farmland or any other type of farmland, conflict with existing zoning for agricultural use or a Williamson Act contract, or otherwise affect an agricultural use. Per sections 12220(g) and 4526 of the California Public Resources Code, the existing high school campus does not meet the definition of forest land or timberland. For these reasons, the proposed project would not result in any impact to agricultural resources. 4.2.3 Conclusion The project would have no impact on agricultural land or agricultural activities. (No Impact)


4.3 AIR QUALITY 4.3.1 Setting 4.3.1.1 Ambient Air Quality Air quality and the amount of a given pollutant in the atmosphere are determined by the amount of pollutant released and the atmosphere’s ability to transport and dilute the pollutant. The major determinants of transport and dilution are wind, atmospheric stability, terrain, and, for photochemical pollutants, sunshine. The Bay Area typically has moderate ventilation, frequent inversions that restrict vertical dilution, and terrain that restricts horizontal dilution. These factors give the Bay Area a relatively high atmospheric potential for pollution.

Ambient Air Quality Standards As required by the Clean Air Act, National Ambient Air Quality Standards (NAAQS) have been established for six major air pollutants: carbon monoxide (CO), nitrogen oxides (NOX), ozone (O3), respirable particulate matter (PM10), fine particulate matter (PM2.5), sulfur oxides, and lead. Pursuant to the California Clean Air Act, the state has also established the California Ambient Air Quality Standards (CAAQS) which are generally more stringent than the corresponding federal standards. The Bay Area Air Quality Management District (BAAQMD) is primarily responsible for assuring that the national and state ambient air quality standards are attained and maintained in the San Francisco Bay Air Basin.

Attainment Status

Santa Clara County, and the Bay Area as a whole, is classified as a nonattainment area for ozone, PM10, and PM2.5 under federal law. The county is either in attainment or unclassified for other pollutants. Ozone, often called photochemical smog, is classified as a secondary air pollutant, meaning it is not emitted directly into the air. It is created by the action of sunlight on ozone precursors, primarily reactive hydrocarbons and NOX. Major sources of ozone precursors include combustion sources such as factories and automobiles and evaporation of solvents and fuels. The main public health concerns associated with ground level ozone pollution are eye irritation and impairment of respiratory functions. PM10 consists of solid and liquid particles of dust, soot, aerosols and other matter which are less than 10 microns in diameter. Major sources of PM10 are combustion (including automobile engines – particularly diesel, fires, and factories) and dust from paved and unpaved roads. Public health concerns associated with PM10 include aggravation of chronic disease and heart/lung disease symptoms. PM2.5, also known as Fine Particulate Matter, consists of the same type of matter as PM10, but is less than 2.5 microns in diameter. The major source of PM2.5 is combustion, but the particles can also be


formed by chemical changes occurring in the air. PM2.5 can cause respiratory problems and is of particular concern because the smaller particles can penetrate deeper into the lungs. The region is required to adopt clean air plans every three years that show progress towards meeting the state ozone standard. The latest regional plan was adopted in September 2010. This plan includes a comprehensive strategy to reduce emissions from stationary, area, and mobile sources through the expeditious implementation of all feasible measures, including transportation control measures (TCMs) and programs such as “Spare the Air.”9 4.3.1.2 Sensitive Receptors The BAAQMD defines sensitive receptors as facilities where sensitive receptor population groups (children, the elderly, the acutely ill, and the chronically ill) are likely to be located. These facilities include residences, school playgrounds, child-care centers, retirement homes, convalescent homes, hospitals, and medical clinics. The nearest sensitive receptors to the project site are Los Gatos High School itself and surrounding residences. 4.3.2 Environmental Checklist and Discussion of Impacts

As discussed in CEQA Guidelines Section 15046(b), the determination of whether a project may have a significant effect on the environment calls for careful judgment on the part of the lead agency and muse be based to the extent possible on scientific and factual data. Lead agencies in the San Francisco Bay Area Air Basin often utilize the thresholds and methodology for assessing air

emissions and/or health effects adopted by BAAQMD based upon the scientific and other factual data prepared by BAAQMD in developing those thresholds. Thresholds prepared and adopted by BAAQMD in May 2011 were the subject of a lawsuit by the California Building Industry Association10 and a subsequent appeal by BAAQMD.11 The Appellate Court decision on August 13, 2013 upheld the thresholds as valid. The determination of whether a project may have a significant effect on the environment is subject to the discretion of each lead agency based upon substantial evidence. The District has carefully considered the thresholds prepared by BAAQMD in May 2011 and regards these thresholds to be based on the best information available for the San Francisco Bay Area Air Basin. Therefore, the analysis in this Initial Study is based on the methodologies and thresholds in the BAAQMD CEQA Air Quality Guidelines. 4.3.2.1 Operational Air Quality Impacts The proposed project would install sports lighting at the existing Los Gatos High School softball field and adjacent multi-use field for use Monday through Sunday during the months of August through June. No new use or intensified use of the fields is proposed to result from the project. All lit events at the softball and multi-use fields would end by 9:00 PM, and the lights would be turned off no later than 9:30 PM. The proposed sports lighting would replace the portable sports lighting that is currently used at the multi-use field during the proposed time period for the same proposed uses; therefore, the proposed project would not increase use of the multi-use field. No spectator seating exists or is proposed at the multi-use field and existing bleacher capacity at the softball field would not be increased; overall spectator attendance is not expected to substantially increase as a result of the project. Similarly, the project will replace existing sports lighting at the baseball and adjacent multi-use field and no change in use or spectator attendance is expected to result from the project. Therefore, the project would not result in a substantial increase in vehicle trips to the Los Gatos High School campus, or vehicle emissions. BAAQMD has developed levels of development below which operational air quality impacts are not expected to occur. The BAAQMD thresholds for high school projects includes projects with building greater than 311,000 square feet in size or projects that increase capacity more than 2,390 students. The proposed project would not construct buildings or otherwise increase the capacity of the high school; therefore, operational air quality impacts are not expected to occur as a result of the project. The portable sports lights that are currently used on the multi-use field are powered by individual diesel generators on each light, which generate exhaust emissions. These portable sports lights and associated exhaust emissions would be replaced by the proposed project. In this way, the project would reduce air pollutant emissions. For this reason and those stated above, the proposed project would not result in a significant air quality impact. (Less Than Significant Impact)

Bay Area Air Quality Management District, Cal. Ct. App. 1st, Case No. A135335, August 13, 2013. The Appellate Court ruled that the BAAQMD CEQA thresholds were adopted using a valid public review process and were supported by substantial evidence.

4.3.2.2 Construction Related Impacts Installation of the proposed sports lighting will require minor excavation for the construction of the footings for the light standard poles and trenching for electrical conduit. Construction activities, such as excavation and grading operations, along with wind blowing over exposed earth would emit exhaust and dust that affect local and regional air quality. Construction activities are also a source of organic gas emissions. Although the proposed project requires only minimal construction, construction dust could affect local air quality and has the potential for creating a nuisance at nearby properties.12 This impact is considered potentially significant. Impact AIR – 1: Construction of the proposed project could result in significant short-term air

quality impacts associated with dust generation. 4.3.3 Mitigation and Avoidance Measures MM AIR – 1: The BAAQMD has prepared lists of feasible construction dust control measures that can reduce construction impacts to a level that is less than

significant.13 The following construction practices shall be implemented to the extent feasible during the proposed project: • All exposed surfaces shall be watered two times per day. • All haul trucks transporting soil, sand, or other loose material off-site

shall be covered. • All visible mud or dirt track-out onto adjacent public roads shall be

removed using wet power vacuum street sweepers at least once per day. The use of dry power sweeping is prohibited.

• All excavation, grading, and/or demolition activities shall be suspended when average wind speeds exceed 20 mph.

• If vegetative ground cover is present prior to construction, it shall be restored as soon as possible.

• Sandbags or other erosion control measures shall be installed to prevent silt runoff to public roadways.

• Post a publicly visible sign with the telephone number and person to contact at the District regarding dust complaints. This person shall respond and take corrective action within 48 hours. The Air District’s phone number shall also be visible to ensure compliance with applicable regulations.

4.3.4 Conclusion The proposed project would replace the existing permanent sports lighting at the Los Gatos High School softball and baseball fields and the multi-use field adjacent to the baseball field, and add permanent sports lighting to the multi-use field adjacent to the softball field. The proposed project

12 The word nuisance is used in this Initial Study to mean “annoying, unpleasant, or obnoxious” and not in its legal sense. 13 Bay Area Air Quality Management District, CEQA Guidelines, 2012, pages 8-3 and 8-4. Los Gatos High School Sports Field Lighting Initial Study Los Gatos-Saratoga Union High School District 30 February 2015

would change or increase the use of the softball, baseball, or multi-use fields, and there would be no or negligible increase in spectator attendance at lit evening events. Therefore, the project would minimally increase vehicle trips to and from the LGHS fields, and operation of the proposed sports lighting would not substantially increase air pollutant emissions. The proposed project would eliminate the current use of diesel generator- powered, portable sports lighting and associated exhaust emissions on the multi-use field. For these reasons and those stated above, the project would not result in significant long-term air quality impacts. Implementation of the mitigation measures described above would reduce short-term air quality impacts associated with project construction to a less than significant level. (Less Than Significant Impact with Mitigation Incorporated)


4.4 BIOLOGICAL RESOURCES 4.4.1 Setting The project site is the existing Los Gatos High School softball, baseball, and adjacent multi-use fields, which are located within a developed suburban area of the Town of Los Gatos. Rare, threatened, endangered and sensitive plants, animals, and natural communities are not expected or likely to occur on the project site. This conclusion is based upon the fact that the site does not contain suitable habitat for any of these species (e.g., marsh, wetland, riparian, or serpentine soils). Los Gatos Creek, a tributary of Guadalupe Creek and the Guadalupe River, flows north in a concrete channel approximately 500 feet northwest of the softball/multi-use fields and 1,100 feet west of the baseball/multi-use fields. Dense mature trees and SR 17 exist between the sports fields and the creek channel. While the concrete channel does not support riparian vegetation, mature trees are located beyond the top of bank and the creek returns to an earthen channel approximately 1,200 feet north of the baseball fields. The dense riparian vegetation along the creek provides a rich habitat for variety of plant and animal species to thrive and disperse, though most animal species using the riparian habitat are accustomed to human disturbance. In the project vicinity, residences are constructed along one side of the channel and Town of Los Gatos baseball field and corporation yard exists on the other side of the channel. 4.4.1.1 Santa Clara Valley Habitat Conservation Plan/Natural Community Conservation

Plan The Santa Clara Valley Habitat Plan/Natural Community Conservation Plan (SCV Habitat Plan), which encompasses a study area of 519,506 acres (or approximately 62 percent of Santa Clara County), was adopted by six local entities in Santa Clara County. The plan went into effect in October 2013 and the newly created Santa Clara Valley Habitat Agency is charged with implementing the plan. The area for which development activities are covered by the plan is located south and east of the Town of Los Gatos, primarily within the Llagas/Uvas/Pajaro, Coyote Creek, and Guadalupe Watersheds. The SCV Habitat Plan was developed through a partnership between Santa Clara County, the Cities of San José, Morgan Hill, and Gilroy, the Santa Clara Valley Water District, and the Santa Clara Valley Transportation Authority (collectively termed the ‘Local Partners’), the U.S. Fish and Wildlife Service, and the California Department of Fish and Wildlife. The Town of Los Gatos is not a participating Local Partner and the Study Area and Permit Area for the SCV Habitat Plan does not include properties within the Town limits. Therefore, properties within the Town of Los Gatos are not subject to or covered by the SCV Habitat Plan.

Three Creeks Habitat Conservation Plan (Under Preparation)

The Three Creeks Habitat Conservation Plan (Three Creeks HCP) is currently being prepared by the Santa Clara Valley Water District (SCVWD).14 The planning area of the Three Creeks HCP encompasses Santa Clara Valley's Coyote Creek, Guadalupe River and Stevens Creek watersheds

below SCVWD reservoirs. Four major tributaries specifically identified in this plan are Calero Creek, Alamitos Creek, Guadalupe Creek and Los Gatos Creek (Lexington Reservoir drains to Los Gatos Creek but is not covered in this HCP). The purpose of the Three Creeks HCP is to identify measures that will minimize and mitigate the effects of SCVWD water supply activities on anadromous fish species15 and their habitats in north Santa Clara County streams. Covered species include Central California coastal steelhead and Central Valley fall-run Chinook salmon. While Los Gatos Creek is subject to the Three Creeks HCP, the project would not affect the creek; therefore, the Three Creeks HCP is not applicable to the proposed project. 4.4.2 Environmental Checklist and Discussion of Impacts

The project sites comprise developed turf sports fields. There are no unique biological features on the project site. Endangered, threatened, special status plant and animal species, or important wildlife breeding, nesting, or feeding areas do not occur on the project site. No trees would be removed as a result of the project and no wetlands would be impacted.

Dense mature trees and SR 17 exist between the fields and Los Gatos Creek. The separation distance, mature trees, and intervening development and activity shield the creek from project activities and any spill light. The possibility of project impacts on wildlife are further reduced given that existing wildlife in the project area is currently exposed to lit evening use of the fields and the proposed lights would be turned off by 9:30 PM for all events. The project would not conflict with any future provisions of the Three Creeks HCP. 4.4.3 Conclusion The proposed replacement of the existing permanent sports lighting at the Los Gatos High School softball and baseball fields and the multi-use field adjacent to the baseball field and portable sports lighting on the multi-use field adjacent to the softball field would not result in significant impacts to biological resources. (No Impact)


4.5 CULTURAL RESOURCES 4.5.1 Setting The project site is the existing Los Gatos High School softball, baseball, and multi-use fields, which are located in a developed suburban area of Los Gatos. Los Gatos Creek is located approximately 500-1,000 feet northwest of the sports fields. Due to the proximity of the creek, the project site is considered an area of archaeological sensitivity. Soils at the project site were previously disturbed during the construction of the sports fields, which required substantial grading and earthwork. For this reason, the potential for intact subsurface archaeological resources to be present at the project site is considered low. There are no historical resources located on or adjacent to the project site that would be affected by the proposed project. The Town of Los Gatos 2020 General Plan Draft EIR cites the University of California Museum of Paleontology in determining that there are no fossil localities within the Town of Los Gatos16, but states that deep excavations could disturb unknown underground paleontological resources. 4.5.2 Environmental Checklist and Discussion of Impacts

The project site is completely developed. Soils at the project site were previously disturbed during the construction of the softball, baseball, and multi-use fields, which required grading and earthwork. Previous ground disturbing activities at the project site did not uncover archaeological or paleontological resources. The project would require relatively shallow excavations for the light standard footings and electrical conduit, which are unlikely to extend into previously undisturbed soils. For these reasons, the potential for subsurface archaeological or paleontological resources to be present at the project site is considered low, and the discovery of resources during excavation to construct the light standard foundations and install electrical conduit is considered unlikely.

There are no historic resources located on or adjacent to the project site that would be affected by the installation of the proposed sports lights at the softball and multi-use fields. Impact CUL – 1: Although unlikely, cultural resources could be uncovered during construction

of the proposed project. 4.5.3 Mitigation and Avoidance Measures MM CUL – 1: The following measure is proposed to reduce impacts to buried cultural

resources to a less than significant level:

• If cultural resources are uncovered during construction of the project, excavation will stop within 25 feet of the find and the Superintendent of Schools will be notified. The find will be evaluated by a professional archaeologist, and if the find is significant, treatment recommendations will be developed and implemented.

4.5.4 Conclusion With the mitigation measure described above, the proposed project would not result in significant impacts to cultural resources. (Less Than Significant Impact with Mitigation Incorporated)


4.6 GEOLOGY AND SOILS 4.6.1 Setting 4.6.1.1 Topography The project site is generally flat and located at the base of the Santa Cruz Mountain foothills. There are no unique geologic features on or adjacent to the project site. Due to the flat topography of the project site, the potential for erosion or landslide on the project site is low. The closest creek is Los Gatos Creek, which flows north in a concrete-lined channel approximately 500 to 1,100 feet northwest of the project site. 4.6.1.2 Soils One soil type covers the softball and adjacent multi-use field, Elpaloalto complex, zero to two percent slopes, and another soil type, Flaskan complex, zero to two percent slopes, covers the baseball and adjacent multi-use field. Both soil types are found in alluvial fans. The Elpaloalto soils are comprised of silty clay loam, are well drained, and are moderately expansive. Flaskan complex soils are comprised of sandy loam to gravelly sandy clay loam and have a low to moderate expansion potential.17 4.6.1.3 Seismicity The project area is located within the seismically active San Francisco Bay Area, which is classified as Zone 4, the most seismically active zone in the United States. The significant earthquakes that occur in the Bay Area are generally associated with crustal movement along the well-defined, active fault zones of the San Andreas Fault system, which regionally trend in a northwesterly direction. The LSHG sports fields are just outside of a fault rupture hazard zone for the San Andreas Fault.18 4.6.1.4 Liquefaction Liquefaction is the result of seismic activity and is characterized as the transformation of loose, water-saturated soils from a solid state to a liquid state upon ground shaking. There are many variables that contribute to liquefaction, including soil age, soil type, soil cohesion, soil density, and ground water level. The project site is located within a designated liquefaction hazard zone.19 Liquefaction can cause differential settlement and lateral spreading, for sites adjacent to open bodies of water, channels, or excavations.

The proposed project would replace the existing permanent sports lighting at the Los Gatos High School softball and baseball fields and the multi-use field adjacent to the baseball field, and add permanent sports lighting to the multi-use field adjacent to the softball field. Installation of the proposed lighting would require minor excavation to construct the footings for the light standards and for electrical conduit. The project site is in a designated liquefaction hazard zone, which would require special consideration in the foundation design for the light standards, to avoid impacts. There are no open faces or water bodies near the project site and, as a result, onsite lateral spreading is not


an issue. There are no other unique geologic hazards (e.g., fault zone, landslide, etc.) specific to the project site. The project site is flat; therefore, the potential for erosion is low. The project does not propose the use of septic or an alternative wastewater disposal system. The proposed light standards would be designed and constructed in conformance with the 2013 California Building Code, which would avoid and minimize potential damage from seismic shaking and seismic-related hazards. The standard measures listed below would be implemented by the proposed project to avoid exposing people or structures to potential substantial adverse effects, including the risk of loss, injury, or death as a result of geologic, soil, and seismic conditions on the project site. Standard Measures: The proposed project will implement the following measures to reduce and avoid impacts related to soil and geologic conditions: • A qualified professional geologist shall complete a design-level geotechnical investigation

for the proposed project. The specific foundation design features identified in the geotechnical investigation for liquefiable soils will be incorporated into the project design.

• The project shall be designed and constructed in accordance with the 2013 California

Building Code, which contains regulations that govern the construction of structures in California. Adherence to the 2013 California Building Code will ensure the proposed improvements resist minor earthquakes without damage and major earthquakes without collapse.

• The design-level drawings, geotechnical investigation, and all accompanying documentation,

including all structural elements of the proposed sports lighting will be subject to the California Division of the State Architect’s (DSA) review and approval process. The primary role of the DSA is to ensure that California's K-12 schools and community colleges are seismically safe and accessible to all. DSA fulfills this role by reviewing project construction plans for structural safety, fire and life safety, and accessibility (that is, access by disabled persons).

4.6.3 Conclusion With implementation of the standard measures described above, the proposed project would not result in significant geologic or seismic impacts. (Less Than Significant Impact)


4.7 GREENHOUSE GAS EMISSIONS 4.7.1 Setting Unlike emissions of criteria and toxic air pollutants, which have local or regional impacts, emissions of Greenhouse Gases (GHGs) have a broader, global impact. Global climate change associated with the “greenhouse effect” is a process whereby GHGs accumulating in the atmosphere contribute to an increase in the temperature in the earth’s atmosphere. The principal GHGs contributing to global climate change are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated compounds. The world’s leading climate scientists have reached the consensus that global climate change is underway and is likely being accelerated by human activity.20 Humans generate GHGs through combustion of fossil fuels (oil, natural gas, and coal) for energy production and transportation, decomposition of solid waste, burning of wood, deforestation, agriculture, and industrial activities. 4.7.1.1 State Regulations Regulatory efforts in California that apply to the project are summarized below:

State of California Executive Order S-3-05 In June 2005, Governor Schwarzenegger issued Executive Order S-3-05 which identified Cal/EPA as the lead coordinating State agency for establishing GHG emission reduction targets in California. A “Climate Action Team,” a multi-agency group was set up to implement Executive Order S-3-05. Under this order, the state plans to reduce GHG emissions to 80 percent below 1990 levels by 2050.

Assembly Bill (AB) 32 – The California Global Warming Solutions Act of 2006

California Assembly Bill (AB) 32 was signed into law in September 2006. The bill requires statewide reductions of GHG emissions to 1990 levels by 2020 and the adoption of rules and regulations to achieve the most technologically feasible and cost-effective GHG emissions reductions.

Senate Bill (SB) 97 – Modification to the Public Resources Code

In August 2007, Governor Schwarzenegger signed SB 97 which required the Office of Planning and Research to prepare, develop, and transmit guidelines to the Resources Agency for the mitigation of GHG emissions or the effects of GHG emissions, including, but not limited to the effects associated with transportation and energy consumption. The Resources Agency adopted the CEQA Guidelines Amendments addressing greenhouse gas emissions on December 30, 2009.

http://climate.nasa.gov/scientific-consensus

SB 375 – Sustainable Communities and Climate Protection Act

SB 375 encourages housing and transportation planning on a regional scale in a manner designed to reduce vehicles use and associated GHG emissions. The bill requires the California Air Resources Board (CARB) to set regional targets for the purpose of reducing GHG emissions from passenger vehicles for 2020 and 2035. Per SB 375, CARB appointed a Regional Targets Advisory Committee (RTAC) on January 23, 2009 to provide recommendations on factors to be considered and methodologies to be used in CARB’s target setting process. The per capita reduction targets set for passenger vehicles in the San Francisco Bay Area are a seven percent reduction by 2020 and a 15 percent reduction by 2035.

BAAQMD CEQA Guidelines

The Bay Area Air Quality Management District (BAAQMD) CEQA Guidelines includes thresholds for analyzing GHG emissions. The BAAQMD CEQA Guidelines also outline a methodology for estimating GHGs, including the use of the URBEMIS model for direct emissions from land use projects. 4.7.1.2 Greenhouse Gas Emissions Under existing conditions, GHG emissions from the project site are primarily the result of combustion of fossil fuels used to transport people to and from the athletic facilities and current activities at the project site. GHG emissions also result from the maintenance of the baseball, softball and multi-use fields and use of diesel-powered portable sports lights on the softball multi-use field. 4.7.2 Environmental Checklist and Discussion of Impacts

4.7.2.1 Greenhouse Gas Emissions The proposed project would replace the existing permanent sports lighting at the Los Gatos High School softball and baseball fields and the multi-use field adjacent to the baseball field, and add permanent sports lighting to the multi-use field adjacent to the softball field. The proposed sports lighting would be used Monday through Sunday during the months of August through June. All lit events at the fields would end by 9:00 PM, and the lights would be turned off by 9:30 PM. The Los Gatos High School Sports Field Lighting Initial Study Los Gatos-Saratoga Union High School District 41 February 2015

proposed sports lighting at the multi-use field adjacent to the softball field would replace the diesel-powered, portable sports lighting that is currently used during the same time period for the same uses; therefore, the proposed project would not increase use of the field. The project would also switch the locations of the softball field and adjacent multi-use field. The project would not change or intensify the use of the fields, and the project is not expected to increase spectator attendance at events on the fields. The project would not increase spectator seating capacity. The BAAQMD has established levels of development below which, operational GHG emission impacts are not expected to occur. The BAAQMD threshold for high school projects is 49,000 square feet of development. The proposed project is well below this threshold. While the addition of new sports lighting could incrementally increase attendance at evening events, the associated incremental increase in GHG emissions from the additional vehicle trips would not result in a significant GHG impact. Given the small nature of the project (i.e., installation of lights at the existing sports fields) and the fact that the fields are located in an urbanized location, within close distance of construction supplies and equipment, project construction would not generate substantial greenhouse gas emissions. The portable sports lights currently used on the multi-use field are self-contained units that are powered by diesel generators, which generate GHG emissions. The use of these portable sports lights and associated GHG emissions on the multi-use field would be eliminated by the proposed project. In this way, the project would reduce GHG emissions. For this reason and those stated above, the project would not would not result in greenhouse gas emissions that would have a significant effect on the environment. (Less Than Significant Impact) 4.7.2.2 Consistency with Applicable GHG Reduction Plans, Policies, and Regulations As discussed above, the project would not generate a substantial volume of greenhouse gases. For this reason, the project would not substantially impede local, regional, or statewide efforts to reduce overall greenhouse gas emissions to 1990 levels or otherwise result in a significant global climate change impact. Sea level rise and temperature changes would not affect the project. (Less Than Significant Impact) 4.7.3 Conclusion Given the overwhelming scope of global climate change, it is not anticipated that the proposed small, facility upgrade project would have an individually discernable effect on global climate change (i.e., that any change in global temperature could be attributed to the emissions resulting from the project). Rather, it is more appropriate to conclude that the GHG emissions generated by the proposed project would combine with emissions across the state, nation, and globe to cumulatively contribute to global climate change. Operation of the proposed sports lighting at the baseball, softball and multi-use fields would not generate a substantial volume of greenhouse gases. For these reasons, the project would not substantially impede local, regional, or statewide efforts to reduce overall GHG emissions to 1990 levels and would not make a cumulatively considerable contribution to global climate change associated with GHG emissions. (Less Than Significant Impact)


4.8 HAZARDS AND HAZARDOUS MATERIALS 4.8.1 Setting The project site is the existing Los Gatos High School softball, baseball, and multi-use fields. Based upon a Phase I Environmental Site Assessment that was prepared for the project, there are no known hazardous material concerns on the project site.21 The project site has been developed as the Los Gatos High School sports fields since approximately 1956. Land uses in the project area include residential, commercial and public (school and church) uses. There are no industrial uses near the project site that pose a hazardous materials risk. The project site does not lie within an airport safety zone or a wildland fire area.22

Government Code Section 65962.5 (Cortese List)

The Hazardous Waste and Substances Sites (Cortese) List is a planning document used by the State, local agencies and developers to comply with the California Environmental Quality Act requirements in providing information about the location of hazardous materials release sites. Government Code section 65962.5 requires the California Environmental Protection Agency to develop at least annually an updated Cortese List. The Cortese List includes lists maintained by the Department of Toxic Substances Control (DTSC), the State Water Resources Control Board (SWRCB), and the California Integrated Waste Management Board (CIWMB)23. The project site is not listed by the DTSC, SWRCB, or CIWMB as a hazardous materials site. 4.8.2 Environmental Checklist and Discussion of Impacts

The proposed project would replace the existing permanent sports lighting at the Los Gatos High School softball and baseball fields and the multi-use field adjacent to the baseball field, and add permanent sports lighting to the multi-use field adjacent to the softball field. The project would not use, transport, dispose, or emit hazardous materials. There are no known hazardous material conditions on or near the project site that pose a safety risk. The project would not result in a safety hazard as a result of being located in an airport use plan or wildfires; nor would it interfere with an emergency response or evacuation plan. Metal halide lamps typically take 10 minutes to come back on after a power outage. In accordance with state law, the District would develop an emergency egress lighting plan to ensure the safe exit of spectators from the bleachers in the event of a power outage. As part of this emergency egress lighting plan, the proposed project includes the installation of battery operated lights on the light standards near bleachers and pathways. In the event that the field lights go out, these battery powered back-up lights would turn on. The handling and ultimate disposal of these batteries would adhere to all applicable federal, state, and local regulations.

4.8.3 Conclusion With implementation of the standard measure listed above, the proposed project would not result in hazardous materials impacts. (No Impact)


4.9 HYDROLOGY AND WATER QUALITY 4.9.1 Setting 4.9.1.1 Water Quality The project site is the existing Los Gatos High School softball, baseball, and multi-use fields, which are located in a developed suburban area in the Town of Los Gatos. A 60-inch storm drain line, owned by the Town of Los Gatos, traverses the site. Onsite catch basins, which connect to the 60-inch storm drain line, collect the stormwater runoff from the fields. The stormwater is discharged to Los Gatos Creek, and eventually enters the San Francisco Bay. Water collected by the storm drain system contains varying amounts of non-point source pollutants associated with urban uses (e.g., oil, litter, brake dust, pesticides, herbicides, etc.). 4.9.1.2 Flooding The project site is not located within the 100-year floodplain.24 The site is within the dam failure inundation hazard zone of Lexington Reservoir, which is contained by the James J. Lenihan Dam, the third largest reservoir in the County. The Santa Clara Valley Water District maintains that the dam has the ability to withstand significant earthquakes; however, in the event of failure, the potential inundation zone is significant.25 With the ongoing maintenance of the Dam, the potential impact to the project is considered less than significant. 4.9.1.3 Seiches, Tsunamis, and Mudflows A seiche is an oscillation of the surface of a lake or landlocked sea varying in period from a few minutes to several hours. There are no landlocked bodies of water near the project site that, in the event of a seiche, will affect the site. A tsunami or tidal wave is a series of water waves caused by the displacement of a large volume of a body of water, such as an ocean or a large lake. Due to the immense volumes of water and energy involved, tsunamis can devastate coastal regions. There are no bodies of water near the project site and the site does not lie within a tsunami inundation area.26 A mudflow is the rapid movement of a large mass of mud formed from loose soil and water. The project area is flat and there are no mountains near the site that, in the event of a mudflow, would affect the site.

4.9.2.1 Water Quality The proposed project would replace the existing permanent sports lighting at the Los Gatos High School softball and baseball fields and the multi-use field adjacent to the baseball field, and add permanent sports lighting to the multi-use field adjacent to the softball field. The lighting would not increase storm water runoff from the project site. The project site is flat; therefore, the potential for erosion on the site is low. For these reasons, the proposed project would not create additional runoff, diminish water quality as a result of erosion, or otherwise substantially degrade water quality. As discussed in Section 4.3 Air Quality, measures to prevent dust, sedimentation, and erosion are included in the proposed project. (No Impact) 4.9.2.2 Other Hydrology and Water Quality Issues The project site is not located in a 100-year flood zone and is not subject to inundation by seiche, tsunami, or mudflow. While the Los Gatos High School campus is located within the dam failure inundation hazard zone of Lexington Reservoir, which is contained by the James J. Lenihan Dam, the Santa Clara Valley Water District maintains the dam and the risk of inundation hazard to the project is considered a less than significant impact. Installation and use of the proposed sports lighting would not use water or interfere with groundwater recharge. Therefore, the proposed project would not result in hydrology and water impacts related to these issues. (No Impact) 4.9.3 Conclusion The proposed project would not result in significant hydrology or water quality impacts. (No Impact)


4.10 LAND USE 4.10.1 Setting The Los Gatos High School campus is developed with classrooms and ancillary uses such as administrative offices, parking lots, a gymnasium, tennis courts, swimming pools and athletic fields, including a track and field stadium and the project site – the softball, baseball and multi-use fields. The Los Gatos High School campus is a designated recreation facility in the Town of Los Gatos General Plan. Land uses surrounding the Los Gatos High School campus include residential, a church, offices and retail uses, and a large hotel complex. State Route 17, a four-lane divided highway, is located immediately north of the softball and adjacent multi-use field. Residences are located immediately west of the softball and adjacent multi-use field, and south and east of the baseball and adjacent multi-use field. Several community buildings owned by the Town of Los Gatos are located within the campus in the wooded area between the softball and multi-use fields and SR 17. An aerial photograph of the project site and the surrounding land uses is shown on Figure 4.10-1. The project site is not located within a Habitat Conservation Plan or Natural Communities Conservation Plan (refer to Section 4.4, Biological Resources). 4.10.2 Environmental Checklist and Discussion of Impacts

Conservation Plan. The project would not result in new or intensified use of the sports fields. Since all of the subject fields currently have sports lighting or use portable lights, the project would not change the time of use of the fields. The project would not increase spectator seating or install a PA system. The project would switch the location of the softball and multi-use field, moving the multi-use field next to the tennis courts and the softball field to the west end of the campus. (No Impact)

Land Use Compatibility

The sports lighting is proposed on an existing high school campus located in a developed area with residential, public, and commercial uses. High schools are normally located and planned adjacent to and within residential areas. The project would not introduce new uses to the campus. Lit evening athletic games and practices currently occur at the Los Gatos High School softball, baseball, and multi-use fields. Lit events also occur at the Los Gatos High School track and field stadium, tennis courts, and swimming pool. The proposed replacement of existing permanent sports lighting at the Los Gatos High School softball and baseball fields and the multi-use field adjacent to the baseball field and addition of permanent sports lighting to the multi-use field adjacent to the softball field, with the athletic activities ending by 9:00 PM and the lights turned off by 9:30 PM, is compatible with the surrounding land uses. The project would not affect the use of the Town-owned buildings located on the Los Gatos High School campus. Switching the location of the multi-use field and softball field would position the multi-use field, which has activity over a longer period throughout the year, farther from residences. This switch is intended to improve the compatibility of the fields with the adjacent residential uses. Switching the softball and multi-use field is not expected to affect operations of the church located just south of the fields, since the church is located at the midpoint where the two fields come together. As discussed in Section 4.1 Aesthetics, Section 4.12 Noise, and Section 4.16 Traffic, the proposed project would not result in significant aesthetic, noise, or traffic impacts that would affect land use compatibility. (No Impact)

Applicable Land Use Plans and Policies

The Town of Los Gatos does not have approval authority over the proposed project, and there are no other agencies with applicable land use plans, policies, or regulations that have jurisdiction over the project. The Los Gatos High School sports fields are recreational facilities serving the local community, as noted in the Town of Los Gatos General Plan. For these reasons, the project would not conflict with an applicable land use plan, policy, or regulation of an agency with jurisdiction over the project that has been adopted for the purpose of avoiding or mitigating an environmental effect. The project design is subject to review and approval by the California Division of the State Architect for structural safety, fire and life safety, and accessibility. (No Impact)

Lick Observatory In recent years, the amount of light produced in the Bay Area has been a growing concern for Lick Observatory, located atop Mount Hamilton east of San Jose. The telescope at the observatory is used from sunset to sunrise every day of the year except Christmas and New Year’s Day. The following guidelines are recommended by the Lick Observatory for lighting in the Santa Clara Valley:27

http://mthamilton.ucolick.org/public/lighting/Summary2.html

• Use of Low Pressure Sodium (LPS) for the majority of street lighting, as well as use of LPS

lighting in public and private development of parking lots. • Use of mixed lighting for areas heavily traveled by pedestrians. • Use of the minimum amount of lighting needed for the intended purpose. • Use of lighting controls, such as timers and dimmers, so lighting is not used when not needed • Control of emitted light by fixture choice, by shielding, and by placement so light is directed

to the ground and not the sky. The project is designed to reduce spill light to the greatest extent feasible. Each fixture has an aluminum reflector, light hood, and visor to direct light onto the field and reduce the amount of spill light (refer to Section 4.1 Aesthetics).28 As recommended by the Illuminating Engineering Society of North America (IESNA), the proposed sports lighting is designed to provide an average light level of 50 and 30 maintained footcandles on the softball and baseball infields and outfields, respectively. The proposed lights would provide an average of 30 and 25 footcandles on the multi-use fields adjacent to the softball and baseball fields, respectively.29 The lights would be turned off by 9:30 PM for all events. The project would replace the use of unshielded, diesel-powered portable sports lights on the multi-use field. For these reasons, the proposed lighting is consistent with the lighting recommendations of Lick Observatory and the project would not substantially affect the operation of the facility. 4.10.3 Conclusion The proposed project consists of improvements to existing softball, baseball, and multi-use fields on an existing high school campus. The proposed project would not physically divide an existing community; nor would the project conflict with applicable land use, habitat conservation, or natural community conservation plans. As discussed in Sections 4.1 Aesthetics, 4.12 Noise, and 4.16 Transportation, the proposed project would not substantially increase light levels, noise, or traffic congestion in the project area. Switching the location of the softball field and multi-use field, as proposed by the project, would improve the compatibility of the multi-use field with adjacent residences. For these reasons and those discussed above, the proposed sports lighting at the Los Gatos High School softball, baseball, and multi-use fields would be compatible with the surrounding land uses and would not result in significant land use impacts. (Less Than Significant Impact)

28 Spill light is any light where it is unintended and unwanted. 29 A footcandle (fc) is one lumen of uniform luminance over an area of one square foot. Los Gatos High School Sports Field Lighting Initial Study Los Gatos-Saratoga Union High School District 52 February 2015

4.12 NOISE The following discussion is based upon the noise study prepared for the proposed project by Illingworth & Rodkin, Inc, noise consultants, in February 2015. The acoustical terms commonly referred to in this section are further defined in the noise study, which is included as Appendix B of this Initial Study. 4.11.1 Existing Setting 4.11.1.1 Noise Background Noise may be defined as unwanted sound. The decibel (dB) is a unit of sound measurement. The A-weighted sound level (dBA) is an adjusted scale that gives greater weight to the frequencies of sound to which the human ear is most sensitive. Most commonly, environmental sounds are described in terms of time averaged noise levels, which is an average of the measured or predicted sound levels over a specified period of time. The Town of Los Gatos uses Community Noise Equivalent Level (CNEL) as a rating of community noise exposure to all sources of sound that differentiates between daytime, evening and nighttime noise, because typical nighttime sleeping hours are when people are most sensitive to noise. It is a measure of the average noise level during a 24-hour day, with the addition of a 5 decibel penalty added to evening (7:00 PM to 10:00 PM) noise and a 10 decibel penalty added to nighttime (10:00 PM to and 7:00 AM) noise. The day/night average noise level (DNL) is essentially the same as CNEL, except the evening time period noise penalty is dropped and all noise occurring during this 3-hour period is grouped with the daytime period. It should be noted that instantaneous noise events such as a horn or whistle may occur that are substantially above the average noise level measured or predicted. 4.11.1.2 Effects of Noise The noise thresholds for speech interference indoors are about 45 dBA if the noise is steady and above 55 dBA if the noise is fluctuating. Outdoors, the thresholds are about 15 dBA higher. Interior residential standards for multi-family dwellings are set by the State of California at 45 dBA DNL. The standard is designed for sleep and speech protection and most jurisdictions apply the same criterion for all residential uses. Typical structural attenuation is 12-17 dBA with open windows. With closed windows in good condition, the noise attenuation factor is around 20 dBA for an older structure and 25 dBA for a newer dwelling. Sleep and speech interference is, therefore, possible when exterior noise levels are about 57-62 dBA DNL with open windows and 65-70 dBA DNL if the windows are closed. Levels of 55-60 dBA are common along collector streets and secondary arterials, while 65-70 dBA is a typical value for a primary/major arterial. Levels of 75-80 dBA are normal noise levels at the first row of development outside a freeway right-of-way. In order to achieve an acceptable interior noise environment, bedrooms facing secondary roadways need to be able to have their windows closed; those facing major roadways and freeways typically need special glass windows.

4.11.1.3 Existing Noise Environment The softball and multi-use fields are located along the west edge of the LGHS campus and are bound by SR 17 to the north, the remainder of the campus to the east, church and commercial uses to the south, and residential uses to the west. The baseball/multi-use fields are located at the northeast end of the campus, with a hotel complex to the north and residential uses to the south and east. An ambient noise monitoring survey was conducted on Wednesday, January 14th through Tuesday, January 20th, 2015 and included one long-term (140-hour) and one short-term (10-minute) measurement. Measurement locations are shown in Figure 4.11-1. Long-term noise measurement LT-1 (along the path just south of the fields) was conducted in consecutive one-hour intervals to document the daily trend in ambient noise levels. During each interval, the average equivalent sound level (Leq), the maximum instantaneous sound level (Lmax), and the sound levels exceeded 1, 10, 50, and 90 percent of the time interval (Ln) were documented. The predominant noise source at the long-term noise measurement location was distant traffic on SR 17. Hourly average noise levels during the daytime ranged from 58 to 62 dBA Leq at location LT-1. The 24-hour average CNEL measured at this location ranged from 55 to 58 dBA. Based on a review of the athletic schedule for LGHS, the only activities occurring on the lower multi-use fields during the measurement period were boys’ soccer events on the evening of Thursday, January 15th. A review of the measurement data indicate that noise levels at LT-1, between 3:00 PM and 5:00 PM, were 62 dBA Leq.

Short-term measurement location ST-1, in front of the Forbes Mill Condominiums, was made between 12:00 PM and 12:10 PM on Tuesday, January 20th, 2015. There were no field activities occurring during the measurement. The primary noise source at this location was traffic on SR 17. Table 4.11-1 summarizes the short-term measurement results. The calculated CNEL at this location was 60 dBA.

Impact Information Source(s)

Would the project result in:

1) Exposure of persons to or generation of noise levels in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies?

9

2) Exposure of persons to, or generation of, excessive groundborne vibration or groundborne noise levels?

9

3) A substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project?

9

4) A substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels existing without the project?

9

5) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels?

9

6) For a project within the vicinity of a private airstrip, would the project expose people residing or working in the project area to excessive noise levels?

9

Of the above-listed guidelines, items (3) and (4) are applicable to the proposed project. Guideline (1) is not applicable, because public school districts are not subject to local plans, codes, or ordinances for their normal operations. Guideline (2) is not applicable, because the project is not located adjacent to, nor would it introduce, any known sources of groundborne vibration. Guidelines (5) and


(6) are not applicable, because the project is not located within an airport land use plan or in the vicinity of a private airstrip. Therefore, checklist items (1), (2), (5), and (6) are not discussed further in this analysis. Significance Criteria The following criteria were used to evaluate the significance of environmental noise resulting from the Project:

• Substantial Permanent Noise Increase. The impact would be considered significant if the project would increase noise levels at noise sensitive receptors by 3 dBA DNL or greater where exterior noise levels would exceed the normally acceptable noise level standard. Where noise levels would remain at or below the normally acceptable noise level standard with the project, noise level increases of 5 dBA DNL or greater would be considered significant. • Construction Noise. Construction noise impacts would be considered significant if hourly average noise levels received at noise sensitive residential land uses are 60 dBA Leq and at least 5 dBA Leq above the ambient noise environment when the duration of the noise-generating activities last for more than one year.

4.11.2.1 Noise Impacts from the Proposed Project The proposed project would replace the existing permanent sports lighting at the Los Gatos High School softball and baseball fields and the multi-use field adjacent to the baseball field, and add permanent sports lighting to the multi-use field adjacent to the softball field. In addition, a site revision would switch the locations of the softball and adjacent multi-use field. LGHS currently uses the fields for baseball, soccer, football practice, and lacrosse practice and games, and band practice. The use of the fields, the time or use, and the intensity of use is not anticipated to change with the project. Current lit evening use on the baseball, softball, and multi-use fields generally occurs during the hours between 5:00 PM and 9:00 PM on Monday through Sunday. Evening softball, soccer, field hockey, and lacrosse games and practice, and band and football practice take place on the softball/multi-use field using the existing lights on the softball field and portable lights powered by diesel generators on the multi-use field adjacent to the softball field. Activities at the baseball/multi-use field include baseball, soccer, and lacrosse games and practice, and band and football practice, also under the existing sports lighting. With the proposed sports lighting, these evening events would remain the same as existing, with all events ending by 9:00 PM and lights turned off no later than 9:30 PM.30 Spectator attendance at the existing lit evening events on the baseball/multi-use and softball/multi-use fields varies between 40 and 60 spectators per game. Spectator attendance is not anticipated to increase with the proposed sports lighting, and no increase in bleacher capacity is proposed. The project does not propose to install a new public address (PA) system.

30 Friday night football games held on the football field extend to midnight. Los Gatos High School Sports Field Lighting Initial Study Los Gatos-Saratoga Union High School District 58 February 2015

Impacts from Baseball/Multi-Use Fields Lit Events

Existing use of the baseball/multi-use fields includes baseball games and practice between January and June, band and football practice between August and December, and soccer and lacrosse games and practice between November and March. Most existing activities occur after school, between the hours of 3:15 PM and 7:00 PM on weekdays, and on weekends until 5:00 PM. Currently, evening events occur on the baseball/multi-use fields until 9:00 PM, using the existing sports lighting. Spectator attendance is typically in the range of 40 to 60 spectators per game. With the replacement of sports lighting at the baseball/multi-use field, the use of the field is anticipated to remain the same as the current use, with all events ending by 9:00 PM and lights turned off no later than 9:30 PM. There were no significant activities occurring on the baseball/multi-use field during the noise monitoring survey. Based on attended measurements conducted during similar events at other high school sporting events31, softball and baseball games can generate noise levels of up to about 57 dBA Leq at a distance of 100 feet from the infield. Maximum noise levels of about 65 dBA at 100 feet typically result from balls being hit and shouting from players and spectators. At the nearest residences (on New York Avenue), located about 200 feet from the center of the infield, average noise levels would be expected to be about 51 dBA and maximum noise levels would be expected to reach 59 dBA. Noise levels generated by field hockey, soccer, and lacrosse games are generally limited to whistles and some cheering. The project does not propose to install a PA system. Typical attendance at each of these games is currently 40 to 60 spectators, which is anticipated to remain the same with the proposed sports lighting project. Based on noise monitoring of similar events at other high school sporting events,32 33 whistles and cheering would be anticipated to generate maximum noise levels of about 58 to 63 dBA Lmax at residences adjoining the multi-use field and band practice would be anticipated to generate noise levels of 45 to 60 dBA Lmax. Hourly average noise levels during these events would be anticipated to be about 56 dBA Leq at residences adjacent to the field (about 150 feet from the center of the multi-use field). Since there would be no change from the existing use, there would be no increase in noise levels above existing levels with the proposed lighting. Replacing the sports lighting at the baseball and adjacent multi-use field with new sports lighting would, therefore, result in a less than significant noise impact. No mitigation is required or proposed. (Less Than Significant Impact)

Impacts from Softball & Multi-Use Fields Lit Events Existing use of the softball/multi-use field includes softball games and practice between January and June, band and football practice from August through December, and soccer and lacrosse practice and games from November through March. Like the baseball fields, most existing activities occur after school, between the hours of 3:15 PM and 7:00 PM on weekdays, and on weekends until 5:00 PM. Evening events currently occur on the softball/multi-use fields until 9:00 PM, using the existing

Los Gatos High School Sports Field Lighting Initial Study Los Gatos-Saratoga Union High School District 59 February 2015

lights on the softball field and the portable lights on the adjacent multi-use field. Spectator attendance is typically in the range of 40 to 60 spectators per game. With the replacement of the sports lighting at the softball field and installation of permanent lighting at the multi-use field, the use of the field is anticipated to remain the same as the current use, with all events ending by 9:00 PM and lights turned off no later than 9:30 PM. The proposed site revisions would switch the locations of the softball and multi-use fields; that is, the multi-use field would be moved adjacent to the tennis courts and the softball field would be moved to the west end of the fields, closest to the residences (refer to Figure 3.1-1). Evening events are currently occurring at the softball/multi-use fields using the existing lights and portable lighting. During the noise monitoring survey, evening soccer events generated a noise level of about 62 dBA Leq at LT-1, located at the southern property line of the existing multi-use field. As described above, softball and baseball games can generate noise levels of up to about 57 dBA Leq at a distance of 100 feet from the infield. Maximum noise levels of about 65 dBA at 100 feet typically result from balls being hit and shouting from players and spectators. Noise levels generated by soccer, and lacrosse games are generally limited to whistles and some cheering, which would be anticipated to generate maximum noise levels of about 58 to 63 dBA Lmax at residences adjoining the field and band practice would be anticipated to generate noise levels of 45 to 60 dBA Lmax. Hourly average noise levels during these events would be anticipated to be about 60 dBA Leq at a distance of about 100 feet from the center of the field.

Although there would be no change in use, the proposed site revisions would result in some small changes in local exposure to field activity noise. The lower fields are currently surrounded by school facilities to the east, a church to the south, and commercial and residential buildings to the southwest. SR 17 adjoins the site to the northwest and north. The softball field, which is currently located to the east of the multi-use field, is only utilized during softball season, which takes place from January to June. The multi-use field, which is currently adjacent to residences to the west and southwest, is utilized year-round. With the proposed site revisions, the multi-use field would be moved further from the residences, resulting in reduced noise exposure overall due to the lighter usage of the softball field. The site plan revision, therefore, would be beneficial, in terms of resident exposure to field noise. At the church, which is located south of the meeting of the two fields, the noise exposure with the site revisions would remain similar to existing conditions. The proposed sports lighting and site plan revision would result in an overall less than significant noise impact. No mitigation is required or proposed. (Less Than Significant Impact)

Project Traffic Noise The proposed replacement and installation of lighting of the LGHS baseball/multi-use fields and softball and multi-use fields is not anticipated to generate substantial traffic above existing conditions, because there would not be a substantial change in uses of the field or a substantial increase in spectators attending practices and games on the fields. Typically, traffic volumes must double, in order to result in a perceptible traffic noise increase. Traffic noise impacts, therefore, are less than significant and no mitigation is required or proposed. (Less Than Significant Impact) Los Gatos High School Sports Field Lighting Initial Study Los Gatos-Saratoga Union High School District 60 February 2015

Construction Noise

Construction activities associated with the project would generate noise over the course of a few months. Installation of the proposed sports lighting would require minor excavation of the field to construct the footings for the light standards and install electrical conduit. This analysis assumes that a small tractor with a backhoe attachment or an excavator would be required to install the electrical conduit and light standard footings. The light standards would then be erected with a mobile crane. Sports lighting project construction activities would occur over a period of approximately five months, with the installation of the lighting occurring over a period of four weeks. Noise impacts resulting from construction depend on the noise generated by various pieces of construction equipment, the timing and duration of noise generating activities, and the distance between construction noise sources and noise sensitive receptors. Where noise from construction activities exceeds 60 dBA Leq and exceeds the ambient noise environment by at least 5 dBA Leq, for a period of one year or more, the impact would be considered significant. Typically, small construction projects do not generate significant noise impacts when standard construction best management practices are enforced at the project site and when the duration of the noise generating construction period is limited to one year or less. Construction noises associated with projects of this type are disturbances that are necessary for the construction or repair of buildings and structures in urban areas. Reasonable regulation of the hours of construction, as well as regulation of the arrival and operation of heavy equipment and the delivery of construction materials, are necessary to protect the health and safety of persons, promote the general welfare of the community, and maintain the quality of life.

In accordance with the Town of Los Gatos Municipal Code (Sec. 16.20.035), construction would occur between the hours of 8:00 a.m. to 8:00 p.m., weekdays and 9:00 a.m. to 7:00 p.m. weekends and holidays, and would meet at least one of the following conditions: 1) no individual piece of equipment shall produce a noise level exceeding eighty-five (85) dBA at twenty-five (25) feet; or 2) the noise level at any point outside of the property plane shall not exceed eighty-five (85) dBA. Construction activities associated with the project would generate noise intermittently over the course of a few months. The noise impact resulting from project construction would be considered less than significant. (Less Than Significant Impact)

Cumulative Noise Impacts The LGHS campus is located in an essentially built-out area of Los Gatos, and there are no reasonably foreseeable projects in the site vicinity which, “when considered together, are considerable or…compound or increase” the noise impacts resulting from the project. The project is not anticipated to generate substantial traffic above existing conditions that would result in increased traffic noise levels. Construction noise impacts or operational noise impacts resulting from the sports lighting project would not combine with noise from other projects in the vicinity, or increased noise levels resulting from the general growth of the area, to increase the severity of project noise impacts as discussed above. (Less Than Significant Impact)


4.11.3 Conclusion The proposed project would not result in the exposure of persons to or generation of excessive noise levels. Installation of sports lighting at the LGHS baseball/multi-use fields and softball/multi-use fields would not change the existing uses of the fields or increase attendance at sporting events. The project would not generate substantial traffic resulting in a perceptible increase in traffic noise and construction would be relatively brief and not require heavy equipment over an extended period. Noise from the project would not substantially increase ambient noise levels. For these reasons, the proposed project would not result in a significant noise impact. (Less Than Significant Impact)


4.13 POPULATION AND HOUSING 4.13.1 Setting The Los Gatos High School campus is located in the Town of Los Gatos, and is one of two high schools within the Los Gatos-Saratoga Union High School District. The Los Gatos-Saratoga Union High School District educates high school students living within the District boundaries. These students live in the housing planned and approved by the cities and town within the District. The District does not construct housing or otherwise affect population and housing. There is no housing located on the District campuses, including Los Gatos High School. 4.13.2 Environmental Checklist and Discussion of Impacts

4.14 PUBLIC SERVICES 4.14.1 Setting 4.14.1.1 Fire Service Fire safety and protection is provided to the Town of Los Gatos by the Santa Clara County Fire Department, which also serves unincorporated Santa Clara County and the communities of Campbell, Cupertino, Los Altos, Los Altos Hills, Monte Sereno, and Saratoga. The Santa Clara County Fire Department serves a total area of approximately 100 square miles and a population of over 226,000 persons. The Santa Clara County Fire Department has 17 fire stations, an administrative headquarters, a maintenance facility, five other support facilities, and more than 100 vehicles. The Department employs 283 personnel to provide fire suppression, emergency medical and fire marshal services, hazardous materials regulation and response, rescue and extrication, public education and fire investigation services. The Department’s suppression force is also augmented by volunteer firefighters. There are three fire stations in the Town of Los Gatos (not counting the County Fire Department headquarters). The closest station to the project is the University Station, #3, located at 306 University Avenue, which is approximately 1,500 feet from the LGHS sports fields and would be the first to respond to any emergencies.34 4.14.1.2 Police Service Public safety services are provided by the Los Gatos/Monte Sereno Police Department, which serves the communities of Los Gatos and Monte Sereno with a combined population of 35,000 residents. The department is comprised of 64 sworn and civilian personnel, and approximately 150 community volunteers.35 There are two Police Captains who report directly to the Chief of Police and are responsible for the management of the department's two Divisions: Operations and Support Services. The Los Gatos/Monte Sereno Police Department civic center complex, which serves as headquarters for administration and dispatch, is located at 110 E. Main Street, Los Gatos, across the street and approximately 1,000 feet from the LGHS sports fields. The Police Operations division is located at 15900 Los Gatos Boulevard, approximately 1.5 miles northeast of the LGHS campus.

1. Would the project result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, the need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for any of the public services:

Fire Protection? Police Protection? Schools? Parks? Other Public Facilities?

1 1 1 1 1

The Los Gatos/Monte Sereno Police Department and Santa Clara County Fire Department currently provide service to Los Gatos High School. Athletic games and practices and band practice are currently held at Los Gatos High School during the daytime and evening hours at the existing athletic fields on the campus. The project proposes replacing sports lighting at the existing baseball/multi-use field and at the softball field, and installing sports lights at the multi-use field adjacent to the softball field to replace the use of portable lights on that field. Therefore, the project would not change the uses of the field, or the time of uses. It is not anticipated that the project would increase attendance at events on the fields such that they would increase demand for police or fire protection services. The proposed installation of lighting at the existing baseball and softball fields and adjacent multi-use fields would not have a long-term effect on schools, parks, or other public facilities in the project area. During project construction, use of the baseball, softball and multi-use fields may be temporarily interrupted, which could increase the use of nearby park facilities. The proposed project would not result in increased demand for schools, parks, or any other public facilities in the project area in such a way that would warrant new facilities. 4.14.3 Conclusion The proposed project would not result in a significant impact on the physical environment as a result of the potential increase in demand for fire protection and police services. The installation of sports lighting at the baseball, softball, and adjacent multi-use fields would not increase the demand on schools, parks, or other public facilities in the project area. (Less than Significant Impact)


4.15 RECREATION 4.15.1 Setting The project site is the existing Los Gatos High School baseball and softball fields and adjacent multi-use fields. Small bleachers are behind home plate of the baseball field and the softball field. No spectator seating is provided at the multi-use fields. Sports lighting currently exists at the baseball/multi-use fields and the softball field. There is no existing sports lighting at the multi-use field adjacent to the softball field; portable lights are currently used for evening practices and events. The softball and adjacent multi-use fields are currently used for softball, soccer, lacrosse, and field hockey games and practices, and football and band practice. The baseball and adjacent multi-use field are currently used for baseball, soccer, and lacrosse practice and games, and football and band practice.

The proposed project would replace existing sports lighting at the LGHS baseball/multi-use fields and the softball field, and install sports lighting at the multi-use field adjacent to the softball field. The project would eliminate the use of inferior, portable sports lighting on the multi-use field adjacent to the softball field and would switch the locations of the softball and multi-use fields, so that the higher use multi-use field is located farther from adjacent residences. The proposed project would not change the existing uses of the field, or the times of practices and events at the fields. The overall use of the sports fields would be identical to existing conditions. The proposed project would improve the existing baseball/multi-use fields and softball and multi-use fields, and would not require the construction or expansion of existing recreational facilities. (No Impact) 4.15.3 Conclusion The proposed project would not result in adverse impacts to recreational facilities in the project area. (No Impact)

4.16.2.1 Transportation Impacts The proposed project would replace the existing sports lighting at the Los Gatos High School baseball/multi-use fields and softball field and install sports lighting at the multi-use field adjacent to the softball field. The lit fields would be used for athletic practice and games and band practice Monday through Sunday during the months of August through June. All lit events at the fields would end by 9:00 PM, and the lights would be turned off no later than 9:30 PM. At the multi-use field adjacent to the softball field, the proposed sports lighting would replace the portable sports lighting that is currently used during the same time period for the same proposed uses; therefore, the proposed project would not increase use of the multi-use field. No new use or change in field use is proposed. The project will not increase bleacher capacity at the baseball or softball fields and no PA system is proposed. For these reasons, overall spectator attendance is not expected to substantially increase as a result of the project and field user and spectator traffic is not expected to increase substantially over existing conditions. The project would not result in impacts to the transportation system serving the project area or impede emergency access.37 Existing pedestrian facilities are adequate to provide safe conditions for pedestrians walking to and from the LGHS sports fields, and the project would not affect air traffic patterns, increase traffic hazards, or conflict with existing public transit, bike, or pedestrian policies. (Less Than Significant Impact) 4.16.3 Conclusion The proposed lighting at the LGHS sports fields would not result in significant transportation impacts. (Less Than Significant Impact)

37 A traffic impact analysis was not completed for the project because, per the VTA Congestion Management Plan Guidelines, preparation of a traffic impact analysis is not required for projects adding less than 100 peak hour trips to the roadway network.

4. Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly?

1-9

4.18.1 Project Impacts The sports lighting is proposed at existing sports fields on an existing high school campus located in a developed suburban area. As discussed previously in the respective sections, the proposed project would not impact biological or cultural resources, would not result in impacts that are individually limited but cumulatively considerable, and would not substantially affect people directly or indirectly. Los Gatos High School is located in a suburban area that is built out. There are no pending projects in the area that together with the proposed project would result in a cumulative impact. The noise study prepared for the proposed lighting project evaluated the cumulative impacts of the project. The study concluded that the proposed lighting project would not result in cumulative impacts. The Los Gatos-Saratoga Union High School District and most other high school districts, private high schools, colleges, and cities in the project area currently own and operate fields with sports lighting similar to the proposed project. The proposed project and the sports lighting at most, if not all, of these fields are designed and operated consistent with the recommendations of the Lick Los Gatos High School Sports Field Lighting Initial Study Los Gatos-Saratoga Union High School District 73 February 2015

Observatory. In addition, the proposed project would eliminate the use of unshielded, portable sports lighting at the Los Gatos High School multi-use field adjacent to the softball field. For these reasons, the proposed replacement of the existing permanent sports lighting at the Los Gatos High School softball and baseball fields and the multi-use field adjacent to the baseball field, and installation of permanent sports lighting on the multi-use field adjacent to the softball field would not result in a cumulative lighting impact. Although the District proposed to install sports lighting at Saratoga High School concurrently with the proposed project, the separation distance between the two high schools is sufficient to avoid significant cumulative aesthetic and biological resource impacts.

INTRODUCTION This report assesses potential noise impacts resulting from the Los Gatos High School Sports Lighting Project proposed in Los Gatos, California. Los Gatos High School (LGHS) is located southeast of Highway 17 and south of Saratoga-Los Gatos Road. The District proposes to replace the existing sports lighting at the baseball/multi-use fields and softball field, and add sports lighting to the adjacent lower, multi-use field at LGHS. In addition, a site revision would switch the locations of the softball and multi-use field. The high school uses the fields for baseball, soccer, football, and lacrosse practices and games, and band practice. The use of the fields is not anticipated to change with the project. The Setting section of this report presents the fundamentals of environmental noise, provides a discussion of policies and standards applicable to the project, and presents the results of the ambient noise monitoring survey. The Impacts and Mitigation Measures section of the report summarizes future noise levels resulting from the project and provides an evaluation of the potential significance of project-related noise impacts. SETTING Background Information on Noise Noise may be defined as unwanted sound. Noise is usually objectionable because it is disturbing or annoying. The objectionable nature of sound could be caused by its pitch or its loudness. Pitch is the height or depth of a tone or sound, depending on the relative rapidity (frequency) of the vibrations by which it is produced. Higher pitched signals sound louder to humans than sounds with a lower pitch. Loudness is intensity of sound waves combined with the reception characteristics of the ear. Intensity may be compared with the height of an ocean wave in that it is a measure of the amplitude of the sound wave. In addition to the concepts of pitch and loudness, there are several noise measurement scales which are used to describe noise in a particular location. A decibel (dB) is a unit of measurement which indicates the relative amplitude of a sound. The zero on the decibel scale is based on the lowest sound level that the healthy, unimpaired human ear can detect. Sound levels in decibels are calculated on a logarithmic basis. An increase of 10 decibels represents a ten-fold increase in acoustic energy, while 20 decibels is 100 times more intense, 30 decibels is 1,000 times more intense, etc. There is a relationship between the subjective noisiness or loudness of a sound and its intensity. Each 10 decibel increase in sound level is perceived as approximately a doubling of loudness over a fairly wide range of intensities. Technical terms are defined in Table 1. There are several methods of characterizing sound. The most common in California is the A-weighted sound level (dBA). This scale gives greater weight to the frequencies of sound to which the human ear is most sensitive. Representative outdoor and indoor noise levels in units of dBA are shown in Table 2. Because sound levels can vary markedly over a short period of time, a method for describing either the average character of the sound or the statistical behavior of the variations must be utilized. Most commonly, environmental sounds are described in terms of an average level that has the same acoustical energy as the summation of all the time-varying events.

This energy-equivalent sound/noise descriptor is called Leq. The most common averaging period is hourly, but Leq can describe any series of noise events of arbitrary duration. The scientific instrument used to measure noise is the sound level meter. Sound level meters can accurately measure environmental noise levels to within about plus or minus 1 dBA. Various computer models are used to predict environmental noise levels from sources, such as roadways and airports. The accuracy of the predicted models depends upon the distance the receptor is from the noise source. Close to the noise source, the models are accurate to within about plus or minus 1 to 2 dBA. Since the sensitivity to noise increases during the evening and at night -- because excessive noise interferes with the ability to sleep -- 24-hour descriptors have been developed that incorporate artificial noise penalties added to quiet-time noise events. The Community Noise Equivalent Level (CNEL) is a measure of the cumulative noise exposure in a community, with a 5 dB penalty added to evening (7:00 pm - 10:00 pm) and a 10 dB addition to nocturnal (10:00 pm - 7:00 am) noise levels. The Day/Night Average Sound Level (DNL or Ldn) is essentially the same as CNEL, with the exception that the evening time period is dropped and all occurrences during this three-hour period are grouped into the daytime period. Effects of Noise Sleep and Speech Interference The thresholds for speech interference indoors are about 45 dBA if the noise is steady and above 55 dBA if the noise is fluctuating. Outdoors the thresholds are about 15 dBA higher. Steady noise of sufficient intensity (above 35 dBA) and fluctuating noise levels above about 45 dBA have been shown to affect sleep. Interior residential standards for multi-family dwellings are set by the State of California at 45 dBA DNL. Typically, the highest steady traffic noise level during the daytime is about equal to the DNL and nighttime levels are 10 dBA lower. The standard is designed for sleep and speech protection and most jurisdictions apply the same criterion for all residential uses. Typical structural attenuation is 12-17 dBA with open windows. With closed windows in good condition, the noise attenuation factor is around 20 dBA for an older structure and 25 dBA for a newer dwelling. Sleep and speech interference is therefore possible when exterior noise levels are about 57-62 dBA DNL with open windows and 65-70 dBA DNL if the windows are closed. Levels of 55-60 dBA are common along collector streets and secondary arterials, while 65-70 dBA is a typical value for a primary/major arterial. Levels of 75-80 dBA are normal noise levels at the first row of development outside a freeway right-of-way. In order to achieve an acceptable interior noise environment, bedrooms facing secondary roadways need to be able to have their windows closed; those facing major roadways and freeways typically need special glass windows. Annoyance Attitude surveys are used for measuring the annoyance felt in a community for noises intruding into homes or affecting outdoor activity areas. In these surveys, it was determined that the causes for annoyance include interference with speech, radio and television, house vibrations, and interference with sleep and rest. The DNL as a measure of noise has been found to provide a valid

2

correlation of noise level and the percentage of people annoyed. People have been asked to judge the annoyance caused by aircraft noise and ground transportation noise. There continues to be disagreement about the relative annoyance of these different sources. When measuring the percentage of the population highly annoyed, the threshold for ground vehicle noise is about 50 dBA DNL. At a DNL of about 60 dBA, approximately 12 percent of the population is highly annoyed. When the DNL increases to 70 dBA, the percentage of the population highly annoyed increases to about 25-30 percent of the population. There is, therefore, an increase of about 2 percent per dBA between a DNL of 60-70 dBA. Between a DNL of 70-80 dBA, each decibel increase increases by about 3 percent the percentage of the population highly annoyed. People appear to respond more adversely to aircraft noise. When the DNL is 60 dBA, approximately 30-35 percent of the population is believed to be highly annoyed. Each decibel increase to 70 dBA adds about 3 percentage points to the number of people highly annoyed. Above 70 dBA, each decibel increase results in about a 4 percent increase in the percentage of the population highly annoyed.

TABLE 1 Definition of Acoustical Terms Used in this Report

Term Definition

Decibel, dB A unit describing, the amplitude of sound, equal to 20 times the logarithm to the base 10 of the ratio of the pressure of the sound measured to the reference pressure. The reference pressure for air is 20 micro Pascals.

Sound Pressure Level Sound pressure is the sound force per unit area, usually expressed in micro Pascals (or 20 micro Newtons per square meter), where 1 Pascal is the pressure resulting from a force of 1 Newton exerted over an area of 1 square meter. The sound pressure level is expressed in decibels as 20 times the logarithm to the base 10 of the ratio between the pressures exerted by the sound to a reference sound pressure (e.g., 20 micro Pascals). Sound pressure level is the quantity that is directly measured by a sound level meter.

Frequency, Hz The number of complete pressure fluctuations per second above and below atmospheric pressure. Normal human hearing is between 20 Hz and 20,000 Hz. Infrasonic sound are below 20 Hz and Ultrasonic sounds are above 20,000 Hz.

A-Weighted Sound Level, dBA

The sound pressure level in decibels as measured on a sound level meter using the A-weighting filter network. The A-weighting filter de-emphasizes the very low and very high frequency components of the sound in a manner similar to the frequency response of the human ear and correlates well with subjective reactions to noise.

Equivalent Noise Level, Leq

The average A-weighted noise level during the measurement period.

Lmax, Lmin The maximum and minimum A-weighted noise level during the measurement period.

L01, L10, L50, L90 The A-weighted noise levels that are exceeded 1%, 10%, 50%, and 90% of the time during the measurement period.

Day/Night Noise Level, Ldn or DNL

The average A-weighted noise level during a 24-hour day, obtained after addition of 10 decibels to levels measured in the night between 10:00 pm and 7:00 am.

Community Noise Equivalent Level, CNEL

The average A-weighted noise level during a 24-hour day, obtained after addition of 5 decibels in the evening from 7:00 pm to 10:00 pm and after addition of 10 decibels to sound levels measured in the night between 10:00 pm and 7:00 am.

Ambient Noise Level The composite of noise from all sources near and far. The normal or existing level of environmental noise at a given location.

Intrusive That noise which intrudes over and above the existing ambient noise at a given location. The relative intrusiveness of a sound depends upon its amplitude, duration, frequency, and time of occurrence and tonal or informational content as well as the prevailing ambient noise level.

Regulatory Background State CEQA Guidelines There are no State laws directly applicable in the assessment of noise associated with new projects. The California Environmental Quality Act (CEQA) includes qualitative guidelines for determining the significance of environmental noise impacts. A project will typically have a significant impact if it would:

(a) Expose people to or generate noise levels in excess of established in the local general plan, noise ordinance, or applicable standards of other agencies.

(b) Expose people to or generate excessive ground-borne vibration or ground-borne noise levels.

(c) Result in a substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project.

(d) Result in a substantial temporary or periodic increase in the ambient noise levels in the project vicinity above levels existing without the project.

(e) Where projects within an area covered by an airport land use plan or within two miles of a public airport or public use airport when such an airport land use plan has not been adopted, or within the vicinity of a private airstrip, expose people residing or working in the project area to excessive aircraft noise levels.

(f) For a project within the vicinity of a private airstrip, expose people residing or working in the project area to excessive noise levels.

Of these guidelines, items (c) and (d) are applicable to the proposed project. Guideline (a) is not applicable because public school districts are not subject to local plans, codes, or ordinances. Guideline (b) is not applicable because the project is not located adjacent to, nor would it introduce, any known sources of groundborne vibration. Guidelines (e) and (f) are not applicable because the project is not located within an airport land use plan or in the vicinity of a private airstrip. Therefore, checklist items (a), (b), (e), and (f) are not carried forward for further analysis. Existing Ambient Noise Environment

The project site is located southeast of Highway 17, between approximately Main Street and Saratoga-Los Gatos Road, in the City of Los Gatos. Residential land uses, commercial uses, and a church bound the site.

An ambient noise monitoring survey was made on Wednesday, January 14th through Tuesday, January 20th, 2015 and included one long-term (140-hour) and one short-term (10-minute) measurement. Measurement locations are shown in Figure 1.

FIGURE 1 Noise Measurement Locations

Long-term noise measurement LT-1 was conducted in consecutive one-hour intervals to document the daily trend in ambient noise levels. During each interval, the average equivalent sound level (Leq), the maximum instantaneous sound level (Lmax), and the sound levels exceeded 1, 10, 50, and 90 percent of the time interval (Ln) were documented. The predominant noise source at the long term measurement location is distant traffic along Highway 17.

Hourly average noise levels during the daytime ranged from 58 to 62 dBA Leq at this location. The 24-hour average CNEL measured at this location ranged from 55 to 58 dBA. Based on a review of the athletic schedule for LGHS, the only activities occurring on the lower multi-use fields during this period were boys’ soccer events on the evening of Thursday, January 15th. A review of these data indicate that noise levels at LT-1, between 3:00 pm and 5:00 pm, were 62 dBA Leq. The results of the long-term measurements are shown in Figure 2.

FIGURE 2 Daily Trends in Noise Levels at LT-1

Short-term measurement location ST-1 was made between 12:00 pm and 12:10 pm on Tuesday, January 20th, 2015. There were no field activities occurring during the measurement. The primary noise source at this location was distant traffic. Table 3 summarizes the short-term measurement results. The calculated CNEL at this location was 60 dBA.

• Substantial Permanent Noise Increase. The impact would be considered significant if the project would increase noise levels at noise sensitive receptors by 3 dBA or greater where exterior noise levels would exceed the normally acceptable noise level standard.

Weekend Soccer

Where noise levels would remain at or below the normally acceptable noise level standard with the project, noise level increases of 5 dBA or greater would be considered significant.

• Construction Noise. Construction noise impacts would be considered significant if hourly

average noise levels received at noise sensitive residential land uses are 60 dBA Leq and at least 5 dBA Leq above the ambient noise environment when the duration of the noise-generating activities last for more than one year.

Impact 1: Project-Generated Noise Increase. Noise resulting from the operation of the

proposed project would not substantially increase noise levels (Leq and Lmax) at receptors in the project vicinity. This is a less than significant impact.

Current use on the baseball, softball, and multi-use fields generally occurs during the hours between 2:00 pm and 9:00 pm on weekdays and during the hours of 8:00 am and 9:00 pm on weekends.1 Evening softball, soccer, field hockey, and lacrosse games and practice, and band and football practice take place on the softball/multi-use field using the existing lights on the softball field and portable lights powered by diesel generators on the multi-use field adjacent to the softball field. Activities at the baseball/multi-use field include baseball, soccer, and lacrosse games and practice, and band and football practice, also under the existing sports lighting. With the proposed sports lighting, these evening events would remain the same as existing, with all events ending by 9:00 pm and lights turned off no later than 9:30 pm. Spectator attendance at the existing and proposed uses at the baseball/multi-use and softball/multi-use fields varies between 40 and 60 spectators per game. Spectator attendance is not anticipated to increase with the proposed sports lighting, and no increase in bleacher capacity is proposed. The project does not propose to install a new public address system. Baseball/Multi-Use Fields Existing use of the baseball/multi-use fields includes baseball games and practice between January and June, band and football practice between August and December, and soccer and lacrosse games and practice between November and March. Most existing activities occur after school, between the hours of 3:15 pm and 7:00 pm on weekdays, and on weekends until 5:00 pm. Currently, evening events occur on the baseball/multi-use fields until 9:00 pm, using the existing sports lighting. Spectator attendance is typically in the range of 40 to 60 spectators per game. With the replacement of sports lighting at the baseball/multi-use field, the use of the field is anticipated to remain the same as the current use, with all events ending by 9:00 pm and lights turned off no later than 9:30 pm. There were no significant activities occurring on the baseball/multi-use field during the noise monitoring survey. Based on attended measurements conducted during similar events at other high school sporting events,2 softball and baseball games can generate noise levels of up to about 57 dBA Leq at a distance of 100 feet from the infield. Maximum noise levels of about 65 dBA at 100 feet typically result from balls being hit and shouting from players and spectators. At the

nearest residences, located about 200 feet from the center of the infield, average noise levels would be expected to be about 51 dBA and maximum noise levels would be expected to reach 59 dBA. Noise levels generated by field hockey, soccer, and lacrosse games are generally limited to whistles and some cheering. The project does not propose to install a P.A. system. Typical attendance at all of these games is currently 40 to 60 spectators, which is anticipated to remain the same with the proposed lighting project. Based on noise monitoring of similar events at other high school sporting events,3,4 whistles and cheering would be anticipated to generate maximum noise levels of about 58 to 63 dBA Lmax at residences adjoining the field and band practice would be anticipated to generate noise levels of 45 to 60 dBA Lmax. Hourly average noise levels during these events would be anticipated to be about 56 dBA Leq at residences adjacent to the field (about 150 feet from the center of the field). Since there would be no change from the existing use, there would be no increase in noise levels above existing levels with the development of the project. This is a less-than-significant impact and no mitigation is recommended. Softball/Multi-Use Fields Existing use of the softball/multi-use field includes softball games and practice between January and June, band and football practice from August through December, and soccer and lacrosse practice and games from November through March. Again, most existing activities occur after school, between the hours of 3:15 pm and 7:00 pm on weekdays, and on weekends until 5:00 pm. Evening events currently occur on the softball/multi-use fields until 9:00 pm, using the existing temporary sports lighting. Spectator attendance is typically in the range of 40 to 60 spectators per game. With the replacement of the temporary sports lighting at the softball/multi-use field with permanent lighting, the use of the field is anticipated to remain the same as the current use, with all events ending by 9:00 pm and lights turned off no later than 9:30 pm. However, the proposed site revisions would switch the locations of the softball and multi-use fields. Evening events are already occurring at the softball/multi-use fields using the existing lights and portable lighting. During the noise monitoring survey, evening soccer events generated a noise level of about 62 dBA Leq at LT-1, located at the southern property line of the existing multi-use field. As described above for the baseball/multi-use fields, softball and baseball games can generate noise levels of up to about 57 dBA Leq at a distance of 100 feet from the infield. Maximum noise levels of about 65 dBA at 100 feet typically result from balls being hit and shouting from players and spectators. Noise levels generated by soccer, and lacrosse games are generally limited to whistles and some cheering, which would be anticipated to generate maximum noise levels of about 58 to 63 dBA Lmax at residences adjoining the field and band practice would be anticipated to generate noise levels of 45 to 60 dBA Lmax. Hourly average noise levels during these events would be anticipated to be about 60 dBA Leq at a distance of about 100 feet from the center of the field. Although there would be no change in use, the site revisions would result in some small changes in local exposure to field activity noise. The lower fields are currently surrounded by school

facilities to the east, a church to the south, and commercial and residential buildings to the southwest. Highway 17 adjoins the site to the northwest. The softball field, which is currently located to the east of the multi-use field, is only utilized during softball season, which takes place from January to June. The multi-use field, which is currently adjacent to residences to the west and southwest, is utilized year-round. With the site revisions, the multi-use field would be moved further from the residences to the west and southwest, resulting in less noise exposure overall due to the lighter usage of the softball field. At the church, which is located south of the meeting of the two fields, the noise exposure with the site revisions would remain similar to existing conditions. This is a less-than-significant impact and no mitigation is recommended. Turf Maintenance With the replacement of the existing natural turf field with synthetic turf, maintenance activities are anticipated to change. Natural turf fields are typically mowed twice weekly during the spring and summer and once monthly during the winter. With the synthetic field turf, typical maintenance activities include brushing and ‘vacuuming’ of the fields. The grooming of synthetic fields typically occurs less often than the natural turf mowing procedures and is anticipated to generate similar noise levels. Typical maximum noise levels are anticipated to range from about 65 to 75 dBA Lmax at a distance of 100 feet. Noise levels typically drop off at a rate of 6 dB per doubling of distance. All maintenance activities would continue to occur during normal school hours. This is a less-than-significant impact and no mitigation is recommended. Project Traffic Noise Traffic studies were not completed for this project because the proposed changes are not anticipated to generate substantial traffic above existing conditions. This is a less-than-significant impact and no mitigation is recommended. Mitigation Measures: None Impact 2: Construction Noise. Noise levels generated by construction activities on the site

would not result in a substantial temporary increase in noise. This is a less than significant impact.

Installation of the proposed lighting system would require minor excavation of the field to complete the site revisions at the lower fields, construct the foundations for the light standards, and replace the natural turf with synthetic turf. Construction activities associated with the sports lighting project would occur over a period of 4.5 months, with the installation of the lighting occurring over a period of 4 weeks. Noise impacts resulting from construction depend on the noise generated by various pieces of construction equipment, the timing and duration of noise generating activities, and the distance between construction noise sources and noise sensitive receptors. Where noise from construction activities exceeds 60 dBA Leq and exceeds the ambient noise environment by at least 5 dBA Leq, for a period of one year or more, the impact would be considered significant. Typically, small construction projects do not generate significant noise impacts when standard construction best management practices are enforced at the project site and when the duration of the noise generating construction period is limited to one year or less. Construction noises

associated with projects of this type are disturbances that are necessary for the construction or repair of buildings and structures in urban areas. Reasonable regulation of the hours of construction, as well as regulation of the arrival and operation of heavy equipment and the delivery of construction materials, are necessary to protect the health and safety of persons, promote the general welfare of the community, and maintain the quality of life. Construction activities associated with the project would generate noise over the course of a few months. The noise impact resulting from project construction would be considered less-than-significant. Mitigation Measures: None Impact 3: Cumulative Noise Impacts. There are no reasonably foreseeable projects in the

site vicinity that would generate construction or operational noise levels, which when combined with the project, would compound or increase the level of impact. This is a less than significant cumulative impact.

The project site is located in an essentially “built-out” area of Los Gatos, and there are no reasonably foreseeable projects in the site vicinity which, “when considered together, are considerable or…compound or increase” the noise impacts resulting from the project. The project is not anticipated to generate substantial traffic above existing conditions. Construction noise impacts or operational noise impacts resulting from the sports lighting project would not combine with noise from other projects in the vicinity, or increased noise levels resulting from the general growth of the area, to increase the severity of project noise impacts as discussed above. Mitigation Measures: None
