1 INTRODUCTION 1.1 Project Overview

The Cajon Valley Union School District (District) intends to install field lighting at its athletic fields at Hillsdale Middle School (project). No field lighting is currently installed at the fields. Lighting would be installed at the existing football/soccer field and at the three existing baseball/softball fields. The baseball/softball fields are located west of the football/soccer field and near the intersection of Brabham Street and Fury Lane.

Once installed, new lighting would facilitate nighttime use of the soccer/football field and baseball/softball fields. Nighttime use of fields would occur 7 days per week, and hours of operation would be until 8:30 p.m. Monday through Friday and until 5:00 p.m. on Saturday and Sunday. Non- school-related use of the fields during evenings is permitted but requires a facilities use permit from the District. District-controlled timers would be installed and programmed to shut off the lights at 8:30 p.m. on weekdays and 5:00 p.m. on weekends (when seasonally needed).

1.2 California Environmental Quality Act Compliance

The California Environmental Quality Act (CEQA) serves as the main framework of environmental law and policy in California. CEQA emphasizes the need for public disclosure and identifying and preventing environmental damage associated with proposed projects. Unless the project or program is deemed categorically or statutorily exempt, CEQA is applicable to any project or program that must be approved by a public agency in order to be processed and established. The project does not fall under any of the statutory or categorical exemptions listed in the 2018 CEQA Statute and Guidelines (PRC Section 21000 et seq.; 14 CCR 15000 et seq.) and, therefore, must meet CEQA requirements.

As detailed in the analysis presented in Section 3, implementation of the project would not result in a significant effect on the environment. Therefore, preparation of a Mitigated Negative Declaration (MND) is appropriate and permitted by CEQA.

1.3 Project Planning Setting

Hillsdale Middle School is located at 1301 Brabham Street in San Diego County, California. The school site is located outside of the El Cajon city limits and is within the unincorporated County of San Diego (County) community of Rancho San Diego. Hillsdale Middle School consists of three parcel that total approximately 23 acres. The campus athletic fields are located west of school buildings and the nearest cross streets to the athletic fields are Brabham Street (located to the north) and Fury Lane (located to the west). The athletic fields are fenced but are open to the

11022 1 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project public during non-school hours. Non-school use of the fields is permitted through a facilities use permit process from the District.

1.4 Public Review Process

In reviewing the Initial Study (IS)/MND, affected public agencies and the interested public should focus on the sufficiency of the document in identifying and analyzing the possible impacts on the environment, as well as the ways in which the significant effects of the project are proposed to be avoided or mitigated.

Comments may be made on the IS/MND in writing before the end of the comment period. A 30- day review and comment period from June 26, 2018 to July 26, 2018, has been established in accordance with Section 15105(b) of the CEQA Guidelines. The IS/MND was distributed and received by the Governor’s Office of Planning and Research (OPR) State Clearinghouse on June 26 and the Notice of Intent (NOI) to adopt an MND was posted on the project site and filed with the San Diego County Clerk’s office on June 26, 2018. The document is available for public review at the District’s Long Range Planning Department office (750 E. Main Street, El Cajon, California 92020). Following the close of the public comment period, the District will consider this IS/MND and comments thereto in determining whether to approve the project. Written comments on the IS/MND should be delivered to the following address by July 26, 2018:

2 SUMMARY OF FINDINGS 2.1 Environmental Factors Potentially Affected

The discussion provided in Section 3 of this IS/MND found that no items would be considered potentially significant as a result of the project. The project would have a less-than-significant impact or no impact on the following areas: aesthetics, agriculture and forestry resources, air quality, biological resources, geology and soils, greenhouse gas emissions, hazards and hazardous materials, hydrology and water quality, land use and planning, mineral resources, noise, population and housing, public services, recreation, transportation and traffic, tribal cultural resources, and utilities and service systems. Due to incorporation of the recommended mitigation measures, potentially significant impacts related to cultural resources (including paleontological resources) would be reduced to a level below significance.

2.2 Environmental Determination

The District finds that the project would not have a significant adverse effect on the environment. Potentially significant effects have been identified, and mitigation measures have been incorporated to ensure that these effects remain at less-than-significant levels. An IS/MND has been prepared to satisfy the requirements of CEQA and the CEQA Guidelines (PRC Section 21000 et seq.; 14 CCR 15000 et seq.).

2.3 Mitigation Measures

The following mitigation measures are required. For the full Mitigation Monitoring and Reporting Program, refer to Section 4.

Mitigation Measure CUL-1: In the unlikely event that archaeological materials are identified in the area during earth-moving activities, work should be temporary halted in the vicinity and archaeologists consulted. A qualified archaeologist should be retained to assess any unanticipated discovery and evaluation efforts of said resource for CRHR and NRHP listing if required. Should human remains be discovered, work will halt in that area, and procedures set forth in the California Public Resources Code (Section 5097.98) and California Health and Safety Code (Section 7050.5) will be followed, beginning with notification to the County Coroner. If Native American remains are present, the County Coroner will contact the Native American Heritage Commission to designate a most likely descendent, who will provide recommendations for the dignified disposition and treatment of the remains.

11022 3 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

Mitigation Measure CUL-2: Since the project is not anticipated to exceed the County’s 2,500 cubic yard grading threshold within undisturbed substratum or deeper bedrock with high or moderate potential, the applicant shall designate a standard monitor to observe all excavations into native, undisturbed sediments to watch for fossils per the County (2009) guidelines. The use of a standard monitor ensures the project is in compliance with Section 87.430 of the Grading Ordinance. If a fossil is recovered that is larger than 12 inches in any dimension, work must be halted in the area of discovery, the Department of Planning and Land Use Permit Compliance Coordinator notified, and a project paleontologist retained by the applicant to assess the significance of the find. If the project paleontologist determines the find to be significant, they shall determine the program for fossil salvage, which includes salvaging, cleaning, and curating the fossil(s), and documenting the find.

3 INITIAL STUDY CHECKLIST

1. Project title: Hillsdale Middle School Field Lighting Project 2. Lead agency name and address: Cajon Valley Union School District 3. Contact person and phone number: Sharon Dobbins, 619.588.3016 4. Project location: The athletic fields are located immediately west of Hillsdale Middle School (located at 1301 Brabham Street). Located outside of the El Cajon city limits, Hillsdale Middle School is within the unincorporated San Diego County community of Rancho San Diego (see Figure 1, Project Location). The nearest cross streets to the athletic fields are Brabham Street (located to the north) and Fury Lane (located to the west). 5. Project sponsor’s name and address: Cajon Valley Union School District 750 E. Main Street, El Cajon, California 92020 6. General plan designation: Public/Semi-Public Facilities (P-SP) 7. Zoning: Residential – Variable (RU) 8. Description of project. (Describe the whole action involved, including but not limited to later phases of the project, and any secondary, support, or off-site features necessary for its implementation. Attach additional sheets if necessary): The District intends to install field lighting at its athletic fields at Hillsdale Middle School. No field lighting is currently installed. Lighting would be installed at the existing football/soccer field and at the three existing baseball/softball fields. The baseball/softball fields are located to the west of the football/soccer field and near the intersection of Brabham Street and Fury Lane. Up to 32 light emitting diode (LED) fixtures would be installed atop four (4) new steel poles (60 to 80 feet high) erected near the football field. Lighting for the baseball/softball fields would include up to 60 total LED fixtures installed atop ten (10) new galvanized steel poles (60 to 80 feet high). New steel poles

11022 5 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

would be erected around the perimeter of the baseball/softball field area. Figure 2, Site Plan, indicates the proposed locations of field light installation. Construction activities would include utility trenching to extend electrical to light pole locations, excavation at pole locations, installation of pre-cast concrete bases with integrated grounding at pole locations, assembly of luminaires and installation of luminaires on poles, and installation of poles on pre-cast concrete basins with the use of a crane. Construction of the project would take approximately 2 months to complete (2 months is a conservative estimate, and activities would likely require a shorter timeframe to complete). Construction activities are anticipated to occur Monday through Friday, 7:00 a.m. to 3:30 p.m. Equipment to be used during construction would include a trencher, small excavator, small truck, drill rig, forklift, and small crane. The duration of individual construction activities and approximate number of workers and type of equipment to be used are listed in Table 1.

Table 1 Construction Activity Details

A conservative estimate of 2 months is assumed for construction activities to cover any additional days for activities. 2 Export of approximately 15 cubic yards of earthwork material would be required following excavation of pole locations. 3 Three truck trips required to transport concrete casts.

Once installed, new lighting would facilitate nighttime use of the soccer/football field and baseball/softball fields. Nighttime use of fields would occur 7 days per week, and hours of operation would be until 8:30 p.m. Monday through Friday and until 5:00 p.m. on Saturday and Sunday. Fields would be used by local sports leagues (use of the fields after school hours is primarily by youth soccer leagues) that would be required to receive a facilities use permit from the District. District-controlled timers would be installed and programmed to shut off the lights at 8:30 p.m. on weekdays and 5:00 p.m. on weekends (when seasonally needed).

9. Surrounding land uses and setting (Briefly describe the project’s surroundings): Hillsdale Middle School is bordered by Brabham Street to the north, Fury Lane to the west, and multifamily apartment developments and Via Rancho San Diego to the south and east. Single-family residential uses are located to the north of Brabham Street, and a swath of vacant, undeveloped property and the main Cuyamaca College campus are located to the west of Fury Lane. A large commercial shopping center, Rancho San Diego Town and Country, is located to the south of Via Rancho San Diego. Businesses include a grocery store, restaurants, auto care facilities, an animal clinic, and a range of personal services. The project site is designated for Public/Semi Public Facilities (P/SP) and is zoned Residential – Variable (RV). General Plan land use and zoning designations applicable to Hillsdale Middle School and the surrounding area are depicted on Figure 3, General Plan Land Use Designation, and Figure 4, Zoning. Land uses surrounding the project site are identified on Figure 5, Surrounding Land Uses. 10. Other public agencies whose approval is required (e.g., permits, financing approval, or participation agreement): The District’s Governing Board must adopt the IS/MND before taking any action on the project. The Governing Board will consider the information contained in this IS/MND when making a decision to approve or deny the project. The analysis in this IS/MND is intended to provide environmental review for the whole of the project in accordance with CEQA requirements. A public agency other than the lead agency that has discretionary approval power over the project is a Responsible Agency, as defined by CEQA Guidelines Section 15381. The Responsible Agencies and their corresponding approvals for the project are as follows:  California Division of the State Architect (approval of construction plans, structural safety, fire and life safety, and access compliance) 11. Have California Native American tribes traditionally and culturally affiliated with the project area requested consultation pursuant to Public Resources Code section 21080.3.1? If so, has consultation begun? To date, California Native American tribes have not requested consultation on projects proposed by the District. On May 2, 2018, Dudek contacted representatives of 20 area tribes listed on the Native American Heritage Commission (NAHC) response letter in order to assist the District with consultation efforts under AB 52. Tribal representatives were provided a letter containing a summary of the project, a figure indicating the location of the project, and a

11022 11 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project general request as to whether the representative or their tribal community had any knowledge of cultural resources, tribal cultural resources, or places that may be impacted by the project. Ray Teran of the Viejas Band of Kumeyaay Indians (“Viejas”) responded to the letter and stated that the tribe had determined that the project site has cultural significance or ties to Viejas. In addition, Mr. Teran requested that a Kumeyaay cultural monitor be on site for ground-disturbing activities to inform the tribe of any new developments, such as inadvertent discovery of cultural artifacts, cremation sites, or human remains. The District will notify Viejas of the construction schedule and allow the tribal monitor to be present during ground disturbing activities. However, due to the prior disturbance of the project site during development of the existing athletic fields, the potential for construction activities to encounter or unearth previously unknown cultural artifacts, cremation sites, or human remains is low. In addition and as detailed in Section 3.5, Cultural Resources, Mitigation Measure CUL-1 would be implemented during construction in the event of an inadvertent discovery of archaeological resources to allow for assessment and evaluation of the resources. Mitigation Measure CUL-1 also contains protocol to be implemented should construction activities uncover human remains. Please refer to Section 3.5 for the full text of Mitigation Measure CUL-1.

Significance

11022 19 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

Determination: (To Be Completed By The Lead Agency)

On the basis of this initial evaluation:

I find that the proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared.

I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because revisions in the project have been made by or agreed to by the project proponent. A MITIGATED NEGATIVE DECLARATION will be prepared.

I find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required.

I find that the proposed project MAY have a “potentially significant impact” or “potentially significant unless mitigated” impact on the environment, but at least one effect (1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and (2) has been addressed by mitigation measures based on the earlier analysis as described on attached sheets. An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to be addressed.

I find that although the proposed project could have a significant effect on the environment, because all potentially significant effects (a) have been analyzed adequately in an earlier ENVIRONMENTAL IMPACT REPORT or NEGATIVE DECLARATION pursuant to applicable standards, and (b) have been avoided or mitigated pursuant to that earlier ENVIRONMENTAL IMPACT REPORT or NEGATIVE DECLARATION, including revisions or mitigation measures that are imposed upon the proposed project, nothing further is required.

Signature Date

11022 20 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

Evaluation of Environmental Impacts:

1. A brief explanation is required for all answers except “No Impact” answers that are adequately supported by the information sources a lead agency cites in the parentheses following each question. A “No Impact” answer is adequately supported if the referenced information sources show that the impact simply does not apply to projects like the one involved (e.g., the project falls outside a fault rupture zone). A “No Impact” answer should be explained where it is based on project-specific factors as well as general standards (e.g., the project will not expose sensitive receptors to pollutants, based on a project-specific screening analysis). 2. All answers must take account of the whole action involved, including off-site as well as on-site, cumulative as well as project-level, indirect as well as direct, and construction as well as operational impacts. 3. Once the lead agency has determined that a particular physical impact may occur, then the checklist answers must indicate whether the impact is potentially significant, less than significant with mitigation, or less than significant. “Potentially Significant Impact” is appropriate if there is substantial evidence that an effect may be significant. If there are one or more “Potentially Significant Impact” entries when the determination is made, an Environmental Impact Report (EIR) is required. 4. “Negative Declaration: Less Than Significant With Mitigation Incorporated” applies where the incorporation of mitigation measures has reduced an effect from “Potentially Significant Impact” to a “Less Than Significant Impact.” The lead agency must describe the mitigation measures, and briefly explain how they reduce the effect to a less than significant level (mitigation measures from “Earlier Analyses,” as described in (5) below, may be cross-referenced). 5. Earlier analyses may be used where, pursuant to the tiering, program EIR, or other CEQA process, an effect has been adequately analyzed in an earlier EIR or negative declaration. Section 15063(c)(3)(D). In this case, a brief discussion should identify the following: a. Earlier Analysis Used. Identify and state where they are available for review. b. Impacts Adequately Addressed. Identify which effects from the above checklist were within the scope of and adequately analyzed in an earlier document pursuant to applicable legal standards, and state whether such effects were addressed by mitigation measures based on the earlier analysis. c. Mitigation Measures. For effects that are “Less than Significant with Mitigation Measures Incorporated,” describe the mitigation measures that were incorporated or

11022 21 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

refined from the earlier document and the extent to which they address site-specific conditions for the project. 6. Lead agencies are encouraged to incorporate into the checklist references to information sources for potential impacts (e.g., general plans, zoning ordinances). Reference to a previously prepared or outside document should, where appropriate, include a reference to the page or pages where the statement is substantiated. 7. Supporting Information Sources: A source list should be attached, and other sources used or individuals contacted should be cited in the discussion. 8. This is only a suggested form, and lead agencies are free to use different formats; however, lead agencies should normally address the questions from this checklist that are relevant to a project’s environmental effects in whatever format is selected. 9. The explanation of each issue should identify: a. The significance criteria or threshold, if any, used to evaluate each question; and b. The mitigation measure identified, if any, to reduce the impact to less than significance

Less Than Potentially Significant with Less Than Significant Mitigation Significant Impact Incorporated Impact No Impact I. AESTHETICS – Would the project: a) Have a substantial adverse effect on a scenic vista? b) Substantially damage scenic resources including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway? c) Substantially degrade the existing visual character

or quality of the site and its surroundings? d) Create a new source of substantial light or glare which would adversely affect day or nighttime views in the area?

11022 22 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

Less Than Potentially Significant with Less Than Significant Mitigation Significant Impact Incorporated Impact No Impact II. AGRICULTURE AND FORESTRY RESOURCES – In determining whether impacts to agricultural resources are significant environmental effects, lead agencies may refer to the California Agricultural Land Evaluation and Site Assessment Model (1997) prepared by the California Department of Conservation as an optional model to use in assessing impacts on agriculture and farmland. In determining whether impacts to forest resources, including timberland, are significant environmental effects, lead agencies may refer to information compiled by the California Department of Forestry and Fire Protection regarding the state’s inventory of forest land, including the Forest and Range Assessment Project and the Forest Legacy Assessment project; and forest carbon measurement methodology provided in Forest Protocols adopted by the California Air Resources Board. Would the project: a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the

Farmland Mapping and Monitoring Program of the California Resources Agency, to non- agricultural use? b) Conflict with existing zoning for agricultural use, or

a Williamson Act contract? c) Conflict with existing zoning for, or cause rezoning of, forest land (as defined in Public Resources Code section 12220(g)), timberland (as defined by

Public Resources Code section 4526), or timberland zoned Timberland Production (as defined by Government Code section 51104(g))? d) Result in the loss of forest land or conversion of

forest land to non-forest use? e) Involve other changes in the existing environment which, due to their location or nature, could result

in conversion of Farmland, to non-agricultural use or conversion of forest land to non-forest use? III. AIR QUALITY – Where available, the significance criteria established by the applicable air quality management or air pollution control district may be relied upon to make the following determinations. Would the project: a) Conflict with or obstruct implementation of the

applicable air quality plan? b) Violate any air quality standard or contribute substantially to an existing or projected air quality violation? c) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or

state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors)? d) Expose sensitive receptors to substantial pollutant

concentrations? e) Create objectionable odors affecting a substantial

11022 30 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

3.1 Aesthetics

a) Would the project have a substantial adverse effect on a scenic vista?

There are no scenic vistas designated in the local Valle de Oro Community Plan (San Diego County 2011a). However, informal trails are located west of the project site and west of Fury Lane and the project site may be visible from select trails identified in the Valle de Oro Community Pathways and Trails Plan (San Diego County 2009) and from local parks. In addition, the project site is visible from Fury Lane and Brabham Lane, which both provide partially obstruct views to mountain terrain, including San Miguel Mountain to the south of the project site.

The project site is visible from informal trails located within the eastern portion of the Cuyamaca College campus to the west of the project site across Fury Lane. This area is an undeveloped water easement area and contains coastal scrub and non-native vegetation. The westerly views provided to users of the informal trails (assumed to college students that park on Fury Lane) are relatively narrow and limited in length by existing landscaping installed along the east side of Fury Lane (including trees on the project site) and two-story apartment buildings to the immediate south of the project site. While southerly views from the trail stretch to mountain terrain to the south of the Sweetwater River, westerly views are comparatively short and not considered scenic vistas. Therefore, implementation of the project and construction and operation of athletic field lighting on the Hillsdale Middle School fields would not impact a scenic vista from the informal trails located to the west of Fury Lane.

The project site is visible from a proposed pathway identified the Valle de Oro Community Trails and Pathways Plan and the proposed field lights may be visible from an existing regional trail and trails located to the south and southwest of the project site. The Wieghorst Loop Trails/Fury Lane Pathway (trail 08 as identified on the Vale De Oro Community Pathways and Trails Plan Map; San Diego County 2009) is a proposed community pathway that parallels Fury Lane. No public right-of-way has been obtained for the proposed pathway at this time. Proposed field lights would be visible to northbound and southbound recreationists on the pathway; however, the tall and thin vertical profile of field light poles would not substantially block or obstruct scenic resources including distant mountain terrain to the south of the project site from view. Similar to existing palm trees and other trees present in southerly views from Fury Lane, the proposed light poles would be visible but would not mask or otherwise hide mountain terrain from view of recreationists. Once installed, proposed field lights may be visible from the existing Sweetwater Regional Trail (aligned along the southern side of Jamacha

11022 31 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

Road), the existing Wildlife Refuge Loop Trail (trail 05; located 0.60 miles to the south of the project site on lands managed by the U.S. Fish and Wildlife Service) and the existing County Loop Trail (02; located 0.65 miles to the southwest of the project site and west of SR-94). Existing northerly views towards the project site from these trails encompasses urban development in the foreground (Sweetwater Regional Trail) or a mix of natural and developed lands. Due to the developed nature of the project area and lower lying elevation of the project site, the introduction of proposed light poles to existing views from these trails would not substantially block or obstruct scenic resources including mountain terrain from view of trail users.

Local parks including Damon Lane County Park and Hilton Head Park are located within 1 mile of the project site. Views of the project site from Damon Lane County Park, located approximately 0.5-mile northwest of the project site, and Hilton Head Park, located approximately 0.7-mile southeast of the project site, are blocked by intervening buildings, structures, and trees. Once installed, proposed light poles would be blocked from view of park users by a similar assortment of intervening elements existing views towards the project site would largely be maintained.

Lastly, the project site is visible from local roads including Fury Lane, and Brabham Street. Fury Road parallels the project site for approximately 480 feet and Brabham Street parallels the project site for approximately 580 feet. A line of tall and mature trees is present along the western extent of the project site and several trees dot the northern border of the project site. Views to the south towards the project site from both roadways consist of metal chain link fences, grass athletics fields, and the dirt infield baseball/softball diamonds. Relatively distant mountain terrain including San Miguel Mountain and McGinty Mountain is visible to motorists near the project site; however, these features are occasionally blocked from view by existing landscaping or residential structures constructed to the east of Fury Lane. Construction activities would be temporary and would not substantially affect existing views to mountain terrain from the roads. Once installed, the tall and thin form of light poles would be present in views for a short duration and would not substantially block or obstruct the broad mountain terrain from view of local motorists.

The project would involve the installation of poles and light fixtures around the perimeter of the athletics fields on the project site. As described above, the project would not block or otherwise impede views of scenic resources as experienced from informal trails, trails identified in the Valle de Oro Community Pathways and Trails Plan, local parks, or local roads. Impacts would be less than significant.

11022 32 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project b) Would the project substantially damage scenic resources including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway?

According to the California Department of Transportation (Caltrans 2018), the nearest eligible state scenic highway is State Route (SR-) 94 from SR-125 near Spring Valley to Interstate 8 near Jacumba. The project site is located approximately 0.6 miles northeast of the SR-94/Jamacha Road intersection. In addition, the San Diego County General Plan designates the segment of SR-94 from SR-125 to Interstate 8 as a County Scenic Highway (San Diego County 2011b). The County also designates Willow Glen Drive from Jamacha Road to Dehesa Road, located 0.3 miles southeast of the project site, as a County Scenic Highway (San Diego County 2011b).

Due to the presence of existing buildings, trees, and other structures, the project site is not visible from nearby segments of SR-94 or Willow Glen Drive. In addition, the highways are not visible from the project site. Once installed, proposed light poles would not be overly visible from SR-94 at the SR-94/Jamacha Road intersection and the majority of individual light poles would be blocked from view by existing development in the Plaza Rancho San Diego shopping center and landscaping. Similarly, the proposed light poles would not be overly visible to westbound/northbound motorists at the Willow Glen Drive/Jamacha Road intersection. Further, project implementation would not entail damage to scenic resources including trees, rock outcroppings, or historic buildings. As such, implementation of the project would not substantially degrade scenic resources within a state scenic highway and impacts would be less than significant. c) Would the project substantially degrade the existing visual character or quality of the site and its surroundings?

The project site consists of natural turf athletics fields surrounded by mature trees. The athletic fields are bordered by 6-foot-high chain-link fencing along Brabham Street, Fury Lane, and the southern boundary with the adjacent multifamily residential development. Three dirt infield baseball/softball diamonds with metallic, chain-link-fence-style backstops are located on the northwestern, northeastern, and southeastern corners of the project site. Hillsdale County Park, a small, oval-shaped park featuring a children’s playground, picnic tables, and an oval-shaped walking path is located to the southwest of the baseball/softball field and abuts Fury Lane. The football/soccer field is located in the eastern portion of the project site and consists of an oval-shaped grass field surrounded by a dirt track. A rectangular paved area is located in the eastern extent of the football/soccer field.

11022 33 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

Uses near the project site include single-family homes to the north across Brabham Street, Hillsdale Middle School tennis and basketball courts and the Hillsdale Middle School main campus to the east, multifamily residential homes to the south, and Hillsdale County Park, Fury Lane and an undeveloped swath of vegetated land to the west of the site. One- and two-story tract homes to the north of Brabham Street are situated approximately 10 feet higher in elevation than the athletic fields on the project site. The northern side of Brabham Street is lined by a row of tall, mature, and regularly spaced palm trees and an approximately 20-foot-wide landscape slope. The Hillsdale Middle School campus features a cluster of primarily one- and two-story buildings that feature landscaping around building perimeters. A large concrete area defines the built boundary of the middle school and is bordered by vegetated lands, access roads, and relatively small parking lots along the eastern extent of campus. The La Vida Real retirement community is located to the east of the Hillsdale Middle School campus. The two- to three-story white stucco exterior and red-tile-roof-topped buildings of the development extend out from the centrally located rental office on the landscaped property. The retirement community is accessible from Via Rancho San Diego and Brabham Street.

Existing photographs of the project site and residences located to the north across Brabham Street are included on Figure 6, Existing Conditions.

Multifamily residential development to the south of the project site consist of a collection of rectangular, two-story buildings painted in neutral exterior colors. In addition to buildings, the development includes pedestrian paths and other hardscape areas, turf and tree landscaping, and paved surface parking lots. A retail shopping center (Rancho San Diego Town and Country) is located south of these apartment complexes near Jamacha Road and Fury Lane and includes several stores and restaurants, a large surface parking lot, and landscaped areas. These stores and restaurants occupy one-story buildings with white painted exteriors and brown terracotta roofs.

Hillsdale County Park is located to the immediate west of the southernmost baseball field located on the project site and consists of a small child’s playground surrounding by sand and a circular pedestrian path. To the west of the project site and across Fury Lane, there is an undeveloped area associated with a Cuyamaca College water easement. The easement area contains low-lying grasses, shrubs, mature trees, and a system of informal and narrow dirt trails. A vegetated riparian corridor is located to the southwest of this undeveloped area within the Cuyamaca College campus. The main Cuyamaca Campus and large parking lot are located to the west and northwest, and the Villa Monte Vina multifamily residential development is located to the south and southwest.

INTENTIONALLY LEFT BLANK

11022 36 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

Construction and operation of new lighting fixtures would alter the existing visual character of the athletics fields by introducing new nighttime lighting and tall metal poles. However, no new land uses are proposed on site, and the athletic fields would continue to support local athletic practices and events. While the fields do not currently feature light poles, tall and thin palm trees dot the Brabham Street corridor and Fury Lane, and new light poles would display a similar thin, vertical form. Regarding lighting, use of the fields would occur 7 days per week. Use would be subject to a facilities use permit from the District, and timers would be installed and programmed to shut off the lights at 8:30 p.m. on weekdays and 5:00 p.m. on weekends (when seasonally needed). In addition, field lighting is relatively commonplace on athletic fields around the County (field lights are installed at nearby Valhalla High School), and the addition of tall and thin vertical features to the fields would be consistent with the character of existing athletic fields in the area. Lastly, due to the thin form of the lighting structures, light poles would not result in substantial blockage of views.

The operation of field lighting would not substantially degrade the existing visual character and quality of the site and surrounding area. The site consists of existing athletic fields of Hillsdale Middle School and is bordered by landscaped roadway corridors to the north and west and by the main Hillsdale Middle School campus and multifamily residential development to the east and south, respectively. As proposed, the tall and thin form of up to 14 light poles (60–80 feet tall) and rectangular banks of luminaires would be visible and would alter the character of the existing athletic fields. Despite the visibility of the poles from nearby roads and land uses, the underlying use of the site would not change and the fields would continue to support practices and sporting events. While no field lights are currently installed on site, the light poles would display a similar form and scale as existing tall and thin palm trees along Brabham Street and Fury Lane. In addition, timers would be installed to limit nighttime lighting effects on nearby land uses. For the reasons described above, the introduction of field lighting would not substantially degrade the existing character and quality of the site and surroundings, and impacts would be less than significant. d) Would the project create a new source of substantial light or glare which would adversely affect day or nighttime views in the area?

Existing sources of nighttime lighting near the project site includes lighting from residences to the north and south of the project site, streetlights installed along Brabham Street, lighting from the Hillsdale Middle school campus, and parking lot lighting from the Cuyamaca College parking lot to the west of the project site across Fury Lane. Commercial development within the Rancho San Diego Town and Country development and streetlights along Jamacha Road also contribute nighttime lighting to the local area

11022 37 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project landscape. Existing sources of glare are relatively limited and generally consist of similar lighting sources as described above.

Construction of the project would take approximately 2 months to complete and would occur Monday through Friday 7:00 a.m. to 3:30 p.m. Because construction activities would cease at 3:30 p.m., the use of temporary lighting sources during construction would not be required.

A photometric study was conducted by Musco Lighting to determine projected light levels from the project. The purpose of the study was to determine potential nighttime lighting impacts associated with project lighting and spillover to nearby residential properties and public roads. According to the study, proposed light fixtures would generate a maximum of 12.6 maintained horizontal foot-candles of light at the base of a single light pole (i.e., A2) installed along the northern extent of the field and would generate an average of 0.83 maintained horizontal foot-candles of light along the boundary of the athletic fields (Musco 2018). The average light levels along the perimeter of the athletic fields would be relatively low, and the use of the field lights would be controlled by timers and lights would be shut off at 8:30 p.m. or 5:00 p.m., depending on season. In addition, the lights would be fully shielded and downward directed to minimize light spillover onto adjacent properties for focus lighting onto fields of play. Use of timers and downward directing of lighting would also reduce opportunities for sky glow and unnecessary illumination of nighttime skies.

Potential impacts associated with lighting would be further reduced through adherence to local lighting regulations. For example, Chapter 6, Conservation, of the Valle de Oro Community Plan contains policies that aim to prevent light spillover impacts (San Diego County 2011a). These include Policy 24, which requires that outdoor lighting fixtures be shaded on top so that all light shines downward, and Policy 25, which requires cut-off luminaires that eliminate unwanted light spillover to be used for outdoor lighting (San Diego County 2011a). In addition, Chapter 2, Light Pollution, of the San Diego County Municipal Code (also referred to as the Light Pollution Code, San Diego County 2018) includes several policies intended to minimize light pollution impacts within the County. The Light

11022 38 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

Pollution Code identifies lighting used for recreational facilities or other similar applications, where color rendition is important for commercial or safety purposes, as Class I lighting. Furthermore, the Light Pollution Code divides the County into two zones for lighting impact evaluation purposes: Zone A is the area within a 15- mile radius of the center of the Palomar Observatory and the area within a 15-mile radius of the center of Mount Laguna Observatory. Zone B refers to all areas within the unincorporated area of the County not included in Zone A. The project site is located in Zone B. Chapter 2 requires Class I lighting that is above 4050 lumens and occurs within Zone B to be fully shielded. As project lighting would be used to illuminate recreational facilities and would include lighting fixtures above 4050 lumens, the project would be subject to Class I lighting regulations applicable to Zone B and lighting would be fully shielded.

District controlled timers would be installed and would limit use of athletic field lighting to 8:30 p.m. on weekdays and 5:00 p.m. on weekends (when seasonally needed). Proposed lights would be fully shielded and downward directed to minimize light spillover onto adjacent properties for focus lighting onto fields of play. In addition, the project would comply with local policies and regulations pertaining to light trespass. The potential generation of glare during operation of the lights would be limited due to the installation of hooded and shielded lighting and limitation of field lighting use associated with the installation of District-controlled timers. For the reasons described above, project lighting and glare impacts would be less than significant and would not adversely affect existing nighttime and daytime views in the area.

3.2 Agriculture and Forestry Resources a) Would the project convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non-agricultural use?

The project site consists of developed recreational fields located on the Hillsdale Middle School campus. Farmland, forest land or timberlands are not located on the project site and construction and operation of the project would not result in the conversion of farmland, forest land or timberland to non-agricultural use. No impact would occur.

11022 39 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project b) Would the project conflict with existing zoning for agricultural use, or a Williamson Act contract?

Please refer to Section 3.2 (a). The project site is zoned for Residential – Variable (RU) and is not in a Williamson Act contract. Therefore, no impact would occur. c) Would the project conflict with existing zoning for, or cause rezoning of, forest land (as defined in Public Resources Code section 12220(g)), timberland (as defined by Public Resources Code section 4526), or timberland zoned Timberland Production (as defined by Government Code section 51104(g))?

Please refer to Section 3.2(a). No impacts to forest land or timberland would occur. d) Would the project result in the loss of forest land or conversion of forest land to non-forest use?

Please refer to Section 3.2(a). No impacts to forest land would occur. e) Would the project involve other changes in the existing environment which, due to their location or nature, could result in conversion of Farmland, to non-agricultural use or conversion of forest land to non-forest use?

Please refer to Section 3.2(a). No impacts to farmland or forest land would occur.

3.3 Air Quality a) Would the project conflict with or obstruct implementation of the applicable air quality plan?

The project is located within the San Diego Air Basin (SDAB), which is under the jurisdiction of the San Diego Air Pollution Control District (SDAPCD). The most recent applicable air quality plans are the San Diego Regional Air Quality Strategy (RAQS) and the San Diego portion of the California Station Implementation Plan (SIP), which aim to reduce local air pollutant emissions for which the SDAB is nonattainment. These plans are based on the San Diego Association of Government’s (SANDAG) population estimates for the region. Therefore, projects that are consistent with SANDAG’s growth projections for the region would not conflict with these plans.

The project would install LED light fixtures atop 14 new steel poles on the perimeter of athletic fields on the Hillsdale Middle School campus. Construction of the project would take approximately 2 months to complete. The project would not induce population

11022 40 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

growth or substantially increase vehicle travel to the project site. Air quality emissions during project construction would not be substantial, due to the minimal amount of earthwork required and limited duration of construction activities. Therefore, the project would not conflict with or obstruct implementation of the RAQS or SIP. Impacts would be less than significant. b) Would the project violate any air quality standard or contribute substantially to an existing or projected air quality violation?

The project would install field lighting around the perimeter of athletic fields at Hillsdale Middle School. Up to 32 total LED fixtures would be installed atop 4 new steel poles that would be erected near the school’s football/soccer field. Lighting for the school’s baseball/softball fields would include up to 60 total LED fixtures installed atop 10 new galvanized steel poles. The project would be required to comply with all relevant federal, state, and local air quality regulations. Nonetheless, the project may generate short-term criteria air pollutant emissions associated with movement of soil, pollutant emissions associated with entrained dust (earth movement), and internal combustion engines used by on-site construction equipment and from off-site worker vehicles and truck trips. However, due to the short duration of construction activities (i.e., 2 months) and limited number of equipment anticipated to be used, construction emissions would be below the SDAPCD daily emission thresholds. Therefore, the project would not violate an air quality standard or contribute to an existing or projected air quality violation. Impacts would be less than significant. c) Would the project result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors)?

The SDAB is designated as a nonattainment area for federal ozone (O3) standards and for state particulate matter 10 microns or less in diameter (PM10) standards and particulate matter 2.5 microns or less in diameter (PM2.5) standards. Movement of soil and pollutant emissions associated with entrained dust (earth movement) and internal combustion engines used by on-site construction equipment and from off-site worker vehicles and truck trips during project construction have the potential to release short-term criteria air pollutants. However, due to the short duration of construction activities, the project would not result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment. The project would not change the land use of

11022 41 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

the project site or produce criteria pollutant emissions during project operation. Therefore, impacts would be less than significant. d) Would the project expose sensitive receptors to substantial pollutant concentrations?

Sensitive receptors in the project vicinity include Hillsdale Middle School students and residences to the north, east, and south of the project site. The nearest residents to the site are located immediately adjacent to the site’s southern boundary. Residences are also located approximately 85 feet to the north of the project site across Brabham Street. Hillsdale County Park is located immediately west of the southern portion of the project site and is bordered by Fury Lane to the west. Lastly, Rancho San Diego Elementary School is located approximately 0.3-mile north of the project site.

Emissions associated with the project would be limited to short-term emissions from on- site earthwork, entrained dust, and internal combustion engines used by on-site construction equipment and from off-site worker vehicles and truck trips during project construction. The project would comply with SDAPCD Rule 55, Fugitive Dust Control, which sets forth provisions for construction activities to reduce visible dust emissions through track-out/carry-out and erosion control measures (SDAPCD 2009). The project would also comply with SDAPCD Rule 50, Visible Emissions, which regulates discharge of visible emissions, and SDAPCD Rule 51, Nuisance, which prohibits discharge of air contaminants that result in injury, detriment, nuisance, or annoyance to a considerable number of people, the public, or to a business or property. Lastly, the project would comply with SDAPCD Rule 52, Particulate Matter, which regulates discharge of particulate matter, and Rule 54, Dust and Fumes, which prohibits emissions of dust or fumes into the atmosphere. Emissions from project construction are temporary and neither construction nor operational emissions would reach a level of significance. Construction and operational emissions would not generate an ongoing, substantial source of emissions that could adversely affect surrounding receptors. As the project would adhere to all applicable policies and standards related to air pollutant emissions and would generate minimal air pollutants during project construction and operations, impacts would be less than significant. e) Would the project create objectionable odors affecting a substantial number of people?

Typical odor generating land uses include manufacturing plants, rendering plants, coffee roasters, wastewater treatment plants, sanitary landfills, and solid waste transfer stations. The project would install field lighting at the existing Hillsdale Middle School football/soccer field and existing baseball/softball fields. Therefore, the project would not include uses that

11022 42 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

would have potential sources of objectionable odors. During construction, the various diesel- powered vehicles and equipment used on site could create localized odors. These odors would be temporary and would not likely be noticeable for extended periods of time beyond the project’s site boundaries. No impact would occur.

3.4 Biological Resources a) Would the project have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Service?

The project site is located in an urbanized area comprised of developed athletic fields on the Hillsdale Middle School campus. The site contains turf athletics fields, baseball/softball diamonds with dirt infields, a dirt track and mature trees that border the north, west and southern site boundary. The site is primarily surrounded by urban development consisting of residential land uses to the north, south, and east. The main Hillsdale Middle School campus is located immediately to the east of the site. An undeveloped swath of land consisting of a water easement and vegetated riparian corridor on the Cuyamaca College campus is located across Fury Lane to the west of the project site. Cuyamaca College, located approximately 95 feet to the west of the project site, also contains a large nature preserve area in the northern and western portions of the campus.

The Grossmont-Cuyamaca Community College District 2013 Facilities Master Plan (GCCCD Master Plan) states that nine California native plant communities exist within the Cuyamaca College site along with six recognized sensitive plant and animal species: the coastal California gnatcatcher, yellow warbler, orange-throated whiptail, coastal whiptail, San Diego blacktailed jackrabbit, and San Diego sunflower (GCCCD 2013). The GCCCD Master Plan states that the northern portion of the water easement located west of the project site and Fury Lane contains disturbed Diegan Coastal Sage Scrub habitat, and the southern portion of the easement contains non-native grassland, coastal scrub, and non-native vegetation. Cuyamaca College proposes to construct a system of decomposed granite trails, raised boardwalks, and observation decks within the water easement and riparian habitat areas. Furthermore, a paved parking lot and community field are proposed to be constructed within the water easement along the eastern boundary of the Cuyamaca College campus adjacent to Fury Lane (GCCCD 2013). As proposed, the community field would be sized to accommodate soccer games and will include restrooms and lighting.

11022 43 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

Due to the severity of past disturbance associated with development of the athletic fields, ongoing active use of the fields and regular field maintenance activities, it is unlikely that special-status plants or animals occur on the project site. However, mature trees are present along the north, west and southern project site boundary and therefore, the District would comply with the Migratory Bird Treaty Act and other applicable regulations protecting nesting and migratory bird species during construction. Therefore, impacts to candidate, sensitive, or special status species would be less than significant. b) Would the project have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Service?

The project site is located in a developed area and supports existing athletic fields at the Hillsdale Middle School campus. There are no riparian or wetland areas on the project site. No impact would occur. c) Would the project have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means?

Refer to Section 3.4(b). There are no federally protected wetlands on the site. No impact would occur. d) Would the project interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites?

Refer to Sections 3.4(a) and (b). The project site is located in a developed area containing recreational fields that are surrounded by residential and school uses. An undeveloped swath of land and vegetated riparian corridor on the Cuyamaca College campus is located to the west of the project site across Fury Lane. Open space areas on the Cuyamaca College campus support several sensitive plant and animal species, including the coastal California gnatcatcher, yellow warbler, orange-throated whiptail, coastal whiptail, San Diego blacktailed jackrabbit, and San Diego sunflower (GCCCD 2013). While the Cuyamaca College campus provides habitat for native resident and migratory wildlife species, the project site is physically separated from the Cuyamaca College campus by Fury Lane. In addition, the project site does not support and is not connected to an established wildlife corridor or nursery site. Therefore, implementation of the project

11022 44 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

would not interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites. Impacts would be less than significant. e) Would the project conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance?

Vegetation on the project site primarily consists of disturbed non-native grass and mature trees that border the athletic fields. The project would install field lighting at athletic fields on the Hillsdale Middle School campus. No trees would be removed as a result of the project. Therefore, the project would not conflict with any local policies or ordinances protecting biological resources. No impact would occur. f) Would the project conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan?

The County adopted the Multiple Species Conservation Plan (MSCP) in 1998 to plan for the preservation of natural vegetation communities and multiple species in the County. The MSCP covers a 900-square-mile area in southwestern San Diego County and includes the City of San Diego, portions of the unincorporated San Diego County, 10 additional city jurisdictions, and several independent special districts (San Diego County 1998). Local jurisdictions implement the MSCP through subarea plans adopted by each jurisdiction, which outline specific implementation measures for the MSCP. The combination of the MSCP and subarea plans (only the South County Subarea Plan has been approved to date) serve as a multiple species Habitat Conservation Plan (HCP) pursuant to Section 10(a)(1)(B) of the federal Endangered Species Act and a Natural Community Conservation Plan (NCCP) pursuant to the California NCCP Act of 1991 and the state Endangered Species Act (San Diego County 1998).

The project site is within the boundaries of the South County Subarea Plan of the MSCP. The South County Subarea Plan proposes several guidelines for development located immediately adjacent to the MSCP preserve. This includes the requirement that lighting within 100 feet of the preserve boundary be confined to areas necessary to ensure public safety, and be low pressure sodium fixtures that are shielded and directed away from the preserve where possible (San Diego County 1997). The project site is located in an urbanized area containing recreational fields surrounded by residential and school uses, and would not be located within 100 feet of the preserve edge.

11022 45 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

The project site is located in an urbanized area containing recreational fields surrounded by residential and school uses. The project would install field lighting at athletic fields on the Hillsdale Middle School campus and would not entail the removal of sensitive habitat from the Subarea Plan or Subarea Plan preserves. Further, LED lighting installed on the athletic fields would shielded and directed onto the field as opposed to off-site and towards distant preserve areas identified in the Subarea Plan. Due to the location of the project site within a developed area containing disturbed vegetation and the installation of shielded and downward directed field lighting, the project would not conflict with an adopted HCP, NCCP, or any other approved local, regional, or state habitat conservation plan. Furthermore, the project site is not within a Resource Conservation Area as defined by the San Diego County General Plan (San Diego County 2010b). Therefore, impacts would be less than significant.

3.5 Cultural Resources a) Would the project cause a substantial adverse change in the significance of a historical resource as defined in §15064.5?

A Negative Phase I Cultural Resources Study Letter report was prepared for the project. The letter report is included as Appendix A to this IS/MND.

The project site has been subject to previous disturbance associated with development of the existing athletic fields including the installation of irrigation lines. The project site encompasses existing athletic fields and does not support historical or built environment resources. Two historic properties are located within the 1-mile search radius of the project site (see Appendix A) and these properties would not be affected during construction or operation of the project. Therefore, no impact to historic resources would occur. b) Would the project cause a substantial adverse change in the significance of an archaeological resource pursuant to §15064.5?

A records search of the project area and a 1-mile radius around the project was conducted by Dudek staff at the California Historic Resources Inventory System (CHRIS) South Coast Information Center (SCIC) at San Diego State University. These records indicate that eight previous studies have intersected or covered the current project area, and no previously recorded resources were identified within the project APE. Please refer to Appendix A for additional detail regarding records search results.

11022 46 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

While SCIC records did not identify any cultural resources within the project APE, there are 29 previous cultural resources recorded in the 1-mile record search area. In total, 15 of the resources are prehistoric resources, including 6 habitation/midden sites, 5 lithic sites, 3 bedrock milling sites, and 1 artifact scatter. Four of the previously recorded resources are multicomponent sites including both prehistoric and historic resources. The remaining 10 historic resources include 2 residential properties and 8 commercial buildings/structures identified in the search buffer.

The entire project APE has been developed as athletic fields, and the SCIC records search, NAHC Sacred Lands File search and Native American outreach did not identify cultural resources within the project APE. As such, no known cultural resources would be impacted by the project, and there is very low potential for the inadvertent discovery of cultural resources during ground breaking activities. However, if previously unknown archaeological materials are uncovered during construction, potentially significant impacts to archaeological resources may occur. Therefore, Mitigation Measure CUL-1 is provided and would be implemented if previously unknown archaeological materials are encountered during construction. With implementation of Mitigation Measure CUL-1, impacts to archaeological resources would be less than significant with mitigation incorporated.

Mitigation Measure CUL-1: In the unlikely event that archaeological materials are identified in the area during earth moving activities, work should be temporarily halted in the vicinity, and archaeologists should be consulted. A qualified archaeologist should be retained to assess any unanticipated discovery and evaluation efforts of said resource for CRHR and NRHP listing if required. Should human remains be discovered, work will halt in that area, and procedures set forth in the California Public Resources Code (Section 5097.98) and California Health and Safety Code (Section 7050.5) will be followed, beginning with notification to the County Coroner. If Native American remains are present, the County Coroner will contact the Native American Heritage Commission to designate a most likely descendent, who will provide recommendations for the dignified disposition and treatment of the remains. c) Would the project directly or indirectly destroy a unique paleontological resource or site or unique geologic feature?

According to surficial geological mapping by Todd et al. (2004) at a scale of 1:100,000, the project site is underlain by Pleistocene (~2.6 million years to 12,000 years ago) to Holocene (< 12,000 years ago) undivided older and younger alluvium and colluvium (map unit Qu). Older (Pleistocene) alluvium and colluvium has yielded significant Ice Age vertebrates,

11022 47 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project including mammoths, mastodons, horses, camels, rabbits, rodents, wolves, saber-toothed cats, birds, turtles, lizards, snakes, frogs, and salamanders, which have been recovered from numerous localities throughout Southern California (Jefferson 1991).

A paleontological records search was requested from the San Diego Natural History Museum (SDNHM) on April 27, 2018, and the results received on May 1, 2018. The paleontological records search is included as Appendix B to this IS/MND. The SDNHM did not report any paleontological localities within a 1-mile radius of the project; however, the older, Pleistocene layers were reported to have produced well-preserved specimens of pond turtle, passenger pigeon, hawk, mole, gopher, squirrel, rabbit, and horse along the southern side of Sweetwater Valley in the Bonita area to the west of the project site (McComas 2018). The surficial deposits are assigned moderate paleontological sensitivity and are likely underlain by Cretaceous (~145 to 66 million years ago) plutonic igneous rocks that have no paleontological sensitivity (McComas 2018). Due to the presence of surficial deposits with moderate paleontological sensitivity in the project area, the SDNHM recommended a complete paleontological mitigation program, which includes paleontological monitoring of excavations into undisturbed, undivided older and younger alluvium and colluvium. Therefore, potential impacts to paleontological resources are considered potentially significant, and Mitigation Measure CUL-2 is provided. With implementation of Mitigation Measure CUL-2, impacts to paleontological resources due to implementation of the project are considered less than significant with mitigation incorporated.

The undivided older and younger alluvium and colluvium underlying the project site is not considered a unique geological feature; therefore, no impact to unique geological features is anticipated with implementation of the project.

11022 48 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project d) Would the project disturb any human remains, including those interred outside of dedicated cemeteries?

As discussed above in Sections 3.5(a)–(c), the project site encompasses existing athletics fields and has previously undergone grading. While human remains are not anticipated to be encountered during construction activities given previous disturbance of the project, Mitigation Measure CUL-1 includes standard procedures that would be implemented if human remains are inadvertently discovered during construction. Per Section 7050.5 of the California Health and Safety Code, if human remains are discovered during project construction, no further work shall occur in the immediate vicinity of the discovered remains until the County Coroner has made the necessary findings as to the origin of the remains. Furthermore, pursuant to California Public Resources Code Section 5097.98(b), remains shall be left in place and free from disturbance until recommendations for treatment have been made. As such, Mitigation Measure CUL-1 has been included and would be implemented to ensure that potential impacts are less than significant with mitigation incorporated by providing standard procedures in the event that human remains are encountered during project construction. 3.6 Geology and Soils a) Would the project expose people or structures to potential substantial adverse effects, including the risk of loss, injury, or death involving:

i. Rupture of a known earthquake fault, as delineated on the most recent Alquist- Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault? Refer to Division of Mines and Geology Special Publication 42.

The Multi-Jurisdictional Hazard Mitigation Plan (MJHMP) for San Diego County shows that the project site is located within the La Nacion Earthquake Fault Zone (San Diego County 2017). The site is located within an area of the fault zone that has the lowest probabilistic peak ground acceleration (PGA) of 0.15% acceleration of gravity (g). The Rose Canyon Fault Zone is located approximately 14.8 miles west of the project site.

The project would install field lighting at athletic fields at Hillsdale Middle School and would not construct any buildings. The project would be designed and constructed to meet the California Building Code (CBC) seismic standards in order to reduce potential damage due to fault rupture. Adherence to the CBC would ensure maximum practicable protection available for users of the project

11022 49 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

site. With compliance with these requirements and recommendations, impacts would be less than significant. ii. Strong seismic ground shaking?

As previously discussed, the project site is located within the La Nacion Fault Zone, an area that is seismically active with numerous known active faults traversing the region. In the event of a major earthquake, ground shaking is a main cause of structural damage. The strength of ground shaking depends on the magnitude of the earthquake, type of fault, and distance from the epicenter. The project is required by state law to comply with the CBC. In addition, compliance with the current regulations would ensure that all lighting structures are designed and built to current standards to minimize impacts associated with ground shaking. Therefore, impacts would be less than significant. iii. Seismic-related ground failure, including liquefaction?

The project site is located in an area that is seismically active with numerous known active faults traversing the region. Ground failure and liquefaction can potentially occur during an earthquake-induced ground-shaking event and can be a main cause of structure damage. Liquefaction occurs when ground shaking causes wet granular soils to change from a solid state to a liquid state, resulting in the collapse of buildings. People and structures are at risk when the ground begins to liquefy and can no longer support structures.

The project would install LED fixtures atop 60–80 foot steel poles at the Hillsdale Middle School athletics fields. According to the MJHMP Liquefaction Map, the project site is located in an area with low liquefaction potential (San Diego County 2017). The MJHMP specifies that liquefaction is not known to have historically occurred within the County (San Diego County 2017). Therefore, it is unlikely that the project site would be susceptible to liquefaction. However, the project is required to comply with the CBC, which outlines specific design, engineering, and development standards for structures proposed in areas with unstable soils. Compliance with the current regulations would ensure that all structures are designed and built to current standards to minimize impacts associated with seismic-related ground failure, including liquefaction. Therefore, impacts would be less than significant. iv. Landslides?

Areas at risk from landslides include locations on or close to steep hills and steep road cuts or excavations, or areas where existing landslides have previously

11022 50 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

occurred. The project site is located on relatively flat ground and is approximately 0.7-mile north of the nearest hills located to the south of the Sweetwater River and north of SR-94. Based on the absence of significant slopes on or within the vicinity of the subject site, the potential for slope failure that could affect the project site is considered negligible. The flat nature of the project site and the distance between the project site and the surrounding hillsides would reduce the risk of landslide hazards. Further, the project is required to comply with the CBC, which outlines specific design, engineering, and development standards for structures proposed in areas with unstable soils. Compliance with current regulations would ensure that all structures are designed and built to current standards to minimize impacts associated with seismic-related ground failure, including landslides. Therefore, impacts would be less than significant. b) Would the project result in substantial soil erosion or the loss of topsoil?

Construction activities associated with the installation of field lights would include utility trenching to extend electrical to light pole locations, excavation of pole locations, installation of pre-cast concrete bases with integrated grounding at pole location, assembly of luminaires and installation of luminaires on poles, and installation on poles on pre-cast concrete basins with the use of a crane. Construction activities would be localized to the area of lighting fixture installation and utility extension. No grading or significant exposure of subsurface soils would occur. Therefore, the project is not expected to result in substantial soil erosion or the loss of topsoil, and impacts would be less than significant. c) Would the project be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction or collapse?

As discussed above, the project site is not expected to be susceptible to geologic hazards such as landslides and liquefaction. In addition, the project is required to comply with the CBC, which outlines specific design, engineering, and development standards for structures proposed in areas with unstable soils. Compliance with current regulations would ensure that buildings would be designed and engineered to withstand impacts of expansive and unstable soils. Therefore, impacts would be less than significant.

11022 51 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project d) Would the project be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code (1994), creating substantial risks to life or property?

The Natural Resources Conservation Service (NRCS) Web Soil Survey identifies three soils on the project site: Fallbrook sandy loam (9%–15% slopes, eroded); Placentia sandy loam, thick surface (2%–9% slopes); and Visalia sandy loam (0%–2% slopes) (NRCS 2017). The majority of the project site is characterized by Visalia sandy loam. This soil possesses a low shrink-swell potential. As described above, the project is required to comply with the CBC, which outlines specific design, engineering, and development standards for structures proposed in areas with unstable and expansive soils. Compliance with current regulations would ensure that buildings would be designed and engineered to withstand impacts of expansive and unstable soils. Therefore, impacts would be less than significant. e) Would the project have soils incapable of adequately supporting the use of septic tanks or alternative waste water disposal systems where sewers are not available for the disposal of waste water?

No septic systems or alternative wastewater disposal systems would be used on the project site. Therefore, no impact would occur. 3.7 Greenhouse Gas Emissions a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment?

The California Air Pollution Control Officers Association (CAPCOA) has published guidance on determining the significance of impacts from project greenhouse gas (GHG) emissions under CEQA in its white paper CEQA and Climate Change (CAPCOA 2008). This white paper includes screening thresholds that can be used to determine whether additional analysis and mitigation are required regarding GHG impacts. The County uses the

annual 900 metric tons of carbon dioxide equivalent (MT CO2e) screening threshold proposed by the CAPCOA white paper to determine if project impacts are significant.

The project would install LED fixtures atop new steel poles near the Hillsdale Middle School football field and baseball/softball fields. The project site does not contain existing lighting. Therefore, the project would generate GHG emissions associated with short-term construction activities and long-term operational activities.

GHG emissions generated by project construction would be temporary in nature and would cease upon completion of the construction phase. GHG emissions during project construction would primarily result from operation of diesel and gasoline-fueled

11022 52 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

construction equipment and vehicles. Project construction would take approximately 2 months to complete. Equipment to be used during construction would include a trencher, small excavator, small truck, drill rig, forklift, and small crane. Due to the short duration of construction and limited number of construction equipment to be used on site, project

construction is anticipated to produce less than the 900 MT CO2e per year threshold.

During project operation, GHG-generating activities are primarily associated with generation of electricity to power the proposed LED light fixtures. According to the U.S. Department of Energy (DOE), LED lighting is a highly energy-efficient form of lighting and consumes considerably less energy than incandescent bulbs (DOE 2018). Musco Lighting estimates that project lighting would have a total energy load of 89.70 kilowatts. Once installed, new lighting is expected to be on during nighttime hours until 8:30 p.m. Monday through Friday, and until 5:00 p.m. on Saturdays and Sundays. Sunset times vary throughout the year between 5:00 p.m. and 8:00 p.m. at the project site. Therefore, project lighting would be used between 0.5 and 3.5 hours per day on average during the week. Assuming that project lighting is used for 3.5 hours every day Monday through Friday, the project would use approximately 81,940.95 kilowatt-hours (kWh) in 1 year. Energy generation associated with these light fixtures would be approximately 61 MT

CO2e per year (EPA 2018). Therefore, project GHG emissions would be considerably less than the CAPCOA GHG emissions threshold of 900 MT CO2e per year, and impacts would be less than significant. b) Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases?

The Scoping Plan, approved by CARB in 2008 (CARB 2008) and updated in 2014 and 2017, provides a framework for actions to reduce California’s GHG emissions and requires CARB and other state agencies to adopt regulations and other initiatives to reduce GHGs. The Scoping Plan is not directly applicable to specific projects, nor is it intended to be used for project-level evaluations. Relatedly, in the Final Statement of Reasons for the Amendments to the CEQA Guidelines, the California Natural Resources Agency (CNRA) observed that “the [Scoping Plan] may not be appropriate for use in determining the significance of individual projects because it is conceptual at this stage and relies on the future development of regulations to implement the strategies identified in the Scoping Plan” (CARB 2008). However, under the Scoping Plan there are several state regulatory measures aimed at the identification and reduction of GHG emissions. CARB and other state agencies have adopted many of the measures identified in the Scoping Plan. Most of these measures focus on area source emissions (e.g., energy usage, high Global Warming Potential GHGs in consumer products) and changes to the vehicle fleet (i.e., hybrid, electric, and more fuel-efficient

11022 53 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

vehicles) and associated fuels (e.g., low-carbon fuel standard), among others. The project would comply with all applicable regulations adopted in furtherance of the Scoping Plan to the extent required by law.

Regarding consistency with post-2020 statewide targets, specifically Senate Bill 32 (goal of reducing GHG emissions to 40% below 1990 levels by 2030) and Executive Order S-3-05 (goal of reducing GHG emissions to 80% below 1990 levels by 2050), there are no established protocols or thresholds of significance for that future-year analysis. However, CARB forecasts that compliance with the current Scoping Plan puts the state on a trajectory of meeting these long-term GHG goals, although the specific path to compliance is unknown. The Scoping Plan Second Update reaffirms that the state is on the path toward achieving the 2050 objective of reducing GHG emissions to 80% below 1990 after the adoption of Senate Bill 32 and Assembly Bill 197 in 2016.

As discussed previously, the project would generate minimal short-term GHG emissions and long-term operational GHG emissions. Operational GHG emissions would be considerably less

than the CAPCOA GHG emissions threshold of 900 MT CO2e per year and as such, construction and operation of the project would not conflict with the state’s trajectory toward future GHG reductions. With respect to future GHG targets under Senate Bill 32 and Executive Order S-3-05, CARB has also made clear its legal interpretation that it has the requisite authority to adopt whatever regulations are necessary, beyond the Assembly Bill 32 horizon year of 2020, to meet the reduction targets in 2030 and in 2050. This legal interpretation by an expert agency provides evidence that future regulations will be adopted to continue the state on its trajectory toward meeting these future GHG targets. Based on the preceding considerations, the project would not conflict with an applicable plan, policy, or regulation adopted to reduce the emissions of GHGs, and impacts would be less than significant. 3.8 Hazards and Hazardous Materials a) Would the project create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials?

During construction activities, a variety of hazardous substances and wastes including fuels for machinery and vehicles would be used on the project site. Construction activities associated with the installation of field lights would include utility trenching to extend electrical to light pole locations, excavation of pole locations, installation of pre-cast concrete bases with integrated grounding at pole location, assembly of luminaires and installation of luminaires on poles, and installation on poles on pre-cast concrete basins with the use of a crane. No uses are proposed that would create a public hazard through transport, use, or disposal. Provisions to comply with existing regulations governing

11022 54 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

transport, use and disposal of hazardous materials and proper management of hazardous substances and wastes during construction are included in construction specifications and are the responsibility of the construction contractors. Therefore, adherence to applicable local, state and federal standards associated with hazardous materials transport, use, and disposal would ensure that these impacts would be less than significant. b) Would the project create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment?

Construction at the project site would involve the temporary use of hazardous and/or flammable materials, including gasoline, and other oils and lubricants. The use, storage, transport, and disposal of these materials during construction and maintenance activities would comply with all existing local, state, and federal regulations, as described above.

A Hazards Assessment Memorandum was prepared by Dudek for the project and is included as Appendix C to this IS/MND. Based on the review of historical aerial photographs, the project site was used for agriculture and was undeveloped or partially developed with secondary roads from 1949 until at least 1979. During initial development of Hillsdale Middle School and its athletic fields, the Department of Toxic Substances Control required that the District remediate any residual pesticides, insecticides, or fertilizers occurring in shallow soils on the site. As such, the District has addressed previous occurrences of residual pesticides, insecticides, or fertilizers resulting from historic use of the school and fields site. According to the District, “Turf Supreme” by Best is currently used to fertilize the athletic fields and is not commonly known as a fertilizer with elevated levels of metals. During construction, the contractor would follow all applicable Occupational Safety and Health Administration (OSHA) regulations for construction and there is low potential for particularly hazardous contaminants to be present in the soil and released into the environment during construction. Therefore, impacts would be less than significant. c) Would the project emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school?

The project would be located on the athletics fields of the Hillsdale Middle School campus. All hazardous materials used during project construction would be handled, stored, transported, used, and disposed of according to all existing local, state, and federal regulations. The project would not involve the routine use, transport, or disposal of hazardous materials during project operation. Therefore, impacts would be less than significant.

11022 55 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project d) Would the project be located on a site that is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment?

As a component of the Hazards Assessment Memorandum (Appendix C to this IS/MND), a search of regulatory records was conducted by Environmental Data Resources (EDR) on April 27, 2018. The search was conducted according to the American Society for Testing and Materials (ASTM) E 1527-13 using standard search radii, which are listed in the EDR report. The EDR report gives a listing of sites within an approximately 1-mile radius of the project site that are known to be chemical handlers, hazardous waste generators, or polluters.

The project site was not found on a list of hazardous material/waste sites pursuant to Government Code Section 65962.5. Hillsdale Middle School was listed in one regulatory databases searched by EDR, HAZNET. The HAZNET database contains information from hazardous waste manifests processed by the Department of Toxic Substances Control. Information for the school indicated that laboratory chemicals were used and sent off site for disposal in 2014. It is likely that this listing is associated with activities in the school buildings and not the athletic fields/project site.

Sixteen (16) sites at ten (10) unique addresses were identified within the ASTM-specified search distances of the project site. The 10 unique sites were listed in 1 or more databases. These databases included LUST, San Diego Co. SAM, SLIC, HAZNET, FINDS, ECHO, EMI, San Diego Co. HMMD, RCRA-SQG, RCRA-CESQG, SWRCY, DRYCLEANERS, AST, UST, SWEEPS UST, HIST CORTESE, and EDR HIST CLEANER. The definitions of these databases can be found in the Hazards Assessment Memorandum. Information provided did not indicate that the project site has been impacted by contamination from any of these nearby sites.

Based on the results from EDR Report for the project site and identified addresses within the ASTM-specified search distances of the project site, construction and operational activities on the site would not create a significant hazard to the public or environment. Impacts would be less than significant. e) 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 result in a safety hazard for people residing or working in the project area?

Lamps Airport, an abandoned and inactive airfield, is located within 0.8-mile of the project site. The nearest active airport to the project site is Gillespie Field, which is located approximately 5.8 miles northwest of the project site. According to the Gillespie Field

11022 56 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

Airport Land Use Compatibility Plan (ALUCP), the project site is not within the Airport Influence Area or within any safety hazard areas (ALUC 2010). The project site is not within 2 miles of an active airport, and project activities would not result in safety hazards for people residing or working in the project area. Therefore, no impact would occur. f) For a project within the vicinity of a private airstrip, would the project result in a safety hazard for people residing or working in the project area?

The project site is not located in the vicinity of a private airstrip. The nearest private airstrip is John Nichols Field, which is located approximately 8.3 miles southeast of the project site. Because the project site is located over 8 miles from the nearest private airstrip, project implementation and the installation of field lights would not result in a safety hazard for people residing or working in the area. Therefore, no impact would occur because of the project. g) Would the project impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan?

Regional access within the project area is provided by SR-94 through Campo Road, Jamacha Road/SR-54, and Jamacha Boulevard. Fury Lane, Willow Glen Drive, Steele Canyon Road, and Jamul Drive are also major roads within the project area. Fury Lane, which borders the project site on the west, is designated as a Major Road from Jamacha Road/SR-54 to Avocado Boulevard (Figure M-A-22; San Diego County 2011a). The project would not require closure of any streets and would not interfere with emergency access to the project site or surrounding area. During project construction, vehicles would access athletics fields directly and would not be staged on the street. Therefore, impacts related to interference with an adopted emergency response plan or emergency evacuation plan would be less than significant. h) Would the project expose people or structures to a significant risk of loss, injury or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands?

The project site is located within a local responsibility area and is not located within a Very High Fire Hazard Severity Zone as designated by the California Department of Forestry and Fire Protection (CAL FIRE) (CAL FIRE 2009). Fire suppression services in the project area would continue to be provided by the San Miguel Consolidated Fire Protection District. As the project is located in a developed urban area and not within a Very High Fire Hazard Severity Zone, construction and operation of the project is not

11022 57 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

anticipated to expose people or structures to a significant risk of loss, injury, or death involving wildfires. Therefore, impacts would be less than significant.

3.9 Hydrology and Water Quality a) Would the project violate any water quality standards or waste discharge requirements?

Construction activities associated with the installation of field lights would include utility trenching to extend electrical to light pole locations, excavation of pole locations, installation of pre-cast concrete bases with integrated grounding at pole location, assembly of luminaires and installation of luminaires on poles, and installation of poles on pre-cast concrete basins with the use of a crane. Soil excavation associated with utility trenching and pole installation could expose disturbed areas to rainfall and stormwater runoff. In addition, accidental/incidental spills of construction-related contaminants (e.g., fuels and oils) could also occur during project construction, thereby degrading water quality. During site operations, surface runoff conditions would be similar to existing conditions.

The County’s Storm Water Management and Discharge Control Ordinance sets forth requirements to protect water resources within the County through the use of best management practices (BMPs) to reduce polluted runoff. The ordinance prohibits polluted non-stormwater discharges to the stormwater conveyance system and requires BMPs that reduce stormwater pollutants to be implemented. Furthermore, the County’s Storm Water Runoff and Drainage Regulations require development to establish erosion prevention, sediment control, and phased grading measures to reduce potential erosion, sedimentation, and water pollution impacts. The project would comply with all applicable local, state, and federal regulations and policies related to the protection of water quality. As a result, impacts to water quality would be less than significant. b) Would the project substantially deplete groundwater supplies or interfere substantially with groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table level (i.e., the production rate of pre-existing nearby wells would drop to a level that would not support existing land uses or planned uses for which permits have been granted)?

The project does not include any uses that would require groundwater and would not impact groundwater recharge within the project site. In addition, construction of project features would not significantly alter the amount of impervious surface area on the project site or result in a substantial increase in staff or customers on the project site that would heighten water demand. The project would not use groundwater nor would it

11022 58 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

substantially interfere with groundwater recharge; therefore, the project would result in a less than significant impact. c) Would the project substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, in a manner which would result in substantial erosion or siltation on- or off-site?

There are no streams or rivers located on or immediately adjacent to the project site. Sweetwater River is located approximately 1,500 feet to the south of the project site.

Construction of project features would not significantly alter the amount of impervious surface area on the project site. The area associated with pre-cast concrete bases at each pole location would be relatively small. As such, the project would not significantly alter the existing drainage pattern of the site or area. As stated previously, project construction would involve some earth-disturbing activities that could expose on-site soils to short- term erosion and surface water runoff. However, inclusion of project BMPs in accordance with the County’s Storm Water Management and Discharge Control Ordinance and Storm Water Runoff and Drainage Regulations, would reduce short-term erosion and siltation from the project site occurring from project construction activities. Installation of project features would not significantly change the amount of impervious surface area on the project site. Therefore, the project would not significantly alter the existing drainage pattern of the site or area in a manner that would result in on- or off-site siltation or erosion; a less than significant impact would occur. d) Would the project substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, or substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or off-site?

As described above, there are no streams or rivers located on or immediately adjacent to the project site. Construction of project features would not significantly alter the amount of impervious surface area on the project site. Stormwater from the project site would continue to be directed into existing drainage features installed below the athletic fields or to storm drains near the project site. The project would not substantially change the drainage pattern on site or increase the rate or amount of surface runoff such that flooding would result on or off site; therefore, a less than significant impact would occur.

11022 59 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project e) Would the project create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff? f) Would the project otherwise substantially degrade water quality?

Response to threshold e) and f). The amount of impervious surfaces subsequent to construction would generally be the same as existing conditions, with the exception of small, pre-cast concrete bases at the light pole locations. The project would not significantly change the amount of impervious surface area on the project site, and the project would not substantially increase the volume of stormwater runoff from the project site. The project would implement BMPs to reduce stormwater pollutants from the site in accordance with the County’s Storm Water Management and Discharge Control Ordinance and Storm Water Runoff and Drainage Regulations. Because the amount of runoff from the project site would not significantly change as a result of the project, and stormwater quality protection measures would be implemented during project construction, the project would not create or contribute runoff water that would exceed the capacity of the local stormwater drainage systems or provide substantial additional sources of polluted runoff from the project site. Therefore, impacts would be less than significant impact. g) Would the project place housing within a 100-year flood hazard area as mapped on a federal Flood Hazard Boundary or Flood Insurance Rate Map or other flood hazard delineation map?

According to the Federal Emergency Management Agency’s Flood Map Number 06073C1931G, dated May 16, 2012, the project site is located in Zone X, which is designated as an area of minimal flood hazard (FEMA 2012). The project does not include housing. Because the project does not include housing or future residents that could be impacted by flooding, no impact regarding the placement of housing within a 100-year flood hazard area would occur. h) Would the project place within a 100-year flood hazard area structures which would impede or redirect flood flows?

As described above, the project is located in an area of minimal flood hazard. Therefore, the project would not place structures within a 100-year flood hazard area that would impede or redirect flood flows, and no impact would occur.

11022 60 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project i) Would the project expose people or structures to a significant risk of loss, injury or death involving flooding, including flooding as a result of the failure of a levee or dam?

As described previously, the project site is located in an area of minimal flood hazard. Furthermore, the San Diego County MJHMP does not designate the project site as being within a dam inundation area or near a dam with a significant risk of failure (San Diego County 2017). Therefore, the project would not expose people or structures to significant loss related to flooding, and no impact would occur. j) Inundation by seiche, tsunami, or mudflow?

According to the San Diego County MJHMP, the project site is located outside the limits of the maximum projected tsunami run-up. Furthermore, the risk potential for damage to the project site caused by seiches is relatively low (San Diego County 2017). The project site is physically removed from any large body of water and is not subject to inundation by seiche, tsunami, or mudflow. The project would have no impact related to these water-related hazards.

3.10 Land Use and Planning a) Would the project physically divide an established community?

The project would be located on a developed and fenced site that currently supports the Hillsdale Middle School football/soccer and baseball/softball fields. The project would install LED light fixtures atop 60- to 80-foot-tall steel poles around the perimeter of the school’s athletic fields. Connectivity between the project site and surrounding areas would be maintained, and no division of an established community would occur. Therefore, no impact would occur. b) Would the project conflict with any applicable land use plan, policy, or regulation of an agency with jurisdiction over the project (including, but not limited to the general plan, specific plan, local coastal program, or zoning ordinance) adopted for the purpose of avoiding or mitigating an environmental effect?

The project site consists of the Hillsdale Middle School football/soccer fields and baseball/softball fields. The site is designated as Public/Semi-Public Facilities (P-SP) on the San Diego County General Plan Land Use Map and is zoned Residential – Variable (RU) (see Figures 3 and 4). The site is bordered by Brabham Street to the north, Fury Lane to the west, and multifamily apartment developments and Via Rancho San Diego to the south and east. Single-family residential uses are located to the north of Brabham

11022 61 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

Street, and a swath of vacant, undeveloped property and the main Cuyamaca College campus are located to the west of Fury Lane. A large commercial shopping center, Rancho San Diego Town and Country, is located to the south of Via Rancho San Diego. Businesses include restaurants, auto care facilities, animal clinics, and a range of personal services. The project would install LED light fixtures atop 60- to 80-foot-high steel poles around the perimeter of the school’s athletic fields.

The San Diego County General Plan sets forth several goals and policies that aim to protect dark skies from lighting and glare impacts. Goal COS-13 aims to preserve dark skies to maintain rural character and is necessary for local observatories. Policy COS-13.2 requires development to restrict exterior light sources within the impact area of the Palomar and Mount Laguna Observatories to minimize impacts on dark skies, and Policy COS-13.3 requires collaboration with adjacent federal and state agencies, local jurisdictions, and tribal governments to reduce light pollution (San Diego County 2011b). In addition, Chapter 6, Conservation, of the Valle de Oro Community Plan contains several policies that aim to prevent light spillover impacts (San Diego County 2011a). These include Policy 24, which requires that outdoor lighting fixtures be shaded on top so that all light shines downward, and Policy 25, which requires cut-off luminaires that eliminate unwanted light spillover to be used for outdoor lighting (San Diego County 2011b). Furthermore, Chapter 2, Light Pollution, of the San Diego County Code of Regulatory Ordinances sets forth policies intended to minimize light pollution impacts within the County. Chapter 2 requires Class I lighting that is above 4050 lumens and occurs within Zone B to be fully shielded, and prohibits these fixtures within Zone A (San Diego County 2018). As the project would not be located within 15 miles of the Palomar Observatory or Mount Laguna Observatory, new lighting would be used to illuminate recreational facilities, and new lighting fixtures would be above 4050 lumens, the project would be subject Chapter 2 requirements concerning full shielding of lighting. The County Municipal Code also requires that all Class I lighting be off between 11:00 p.m. and sunrise, with certain exceptions, including allowing an organized recreational event in progress to be completed if the event and the facility comply with County permits, laws, and regulations.

As described in Section 3.1(d), the project would adhere to applicable local, state, and federal regulations and policies and would not conflict with any applicable land use plan, policy, or regulation of an agency with jurisdiction over the project. Please refer to Section 3.1(d) regarding the project and project features that would minimize lighting and glare impacts. Therefore, impacts would be less than significant .

11022 62 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project c) Would the project conflict with any applicable habitat conservation plan or natural community conservation plan?

The project site is within the boundaries of the San Diego County MSCP. The South County Subarea Plan implements the San Diego County MSCP for the project area. The South County Subarea Plan proposes several guidelines for development located immediately adjacent to the MSCP preserve. This includes the requirement that lighting within 100 feet of the preserve boundary be confined to areas necessary to ensure public safety, and be low pressure sodium fixtures that are shielded and directed away from the preserve where possible (San Diego County 1997). The project site is located in an urbanized area containing recreational fields surrounded by residential and school uses, and would not be located within 100 feet of the preserve edge.

The project would install field lighting at athletic fields on the Hillsdale Middle School campus. As described in Section 3.1(d), the project would be subject to Class I lighting regulations applicable to Zone B, and lighting installed on the project site would be downward directed and fully shielded. In addition, District-controlled timers would be installed and would limit use of athletic field lighting to 8:30 p.m. on weekdays and 5:00 p.m. on weekends (when seasonally needed). Due to the location of the project site within a developed area supporting existing athletic fields, and because athletic field lights would be directed downwards and shielded, the project would not conflict with an adopted HCP, NCCP, or any other approved local, regional, or state habitat conservation plan. Therefore, impacts related to conflicts with an adopted plan would be less than significant . 3.11 Mineral Resources a) Would the project result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the state?

The project site is currently developed with the existing Hillsdale Middle School athletics fields and does not serve as a mineral resource recovery site. According to California Department of Conservation (CDOC) Mineral Land Classification Maps, the project site is located within MRZ-1, an area where adequate information indicates than no significant mineral deposits are present, or where it is judged that little likelihood exists for their presence (CDOC 1983). Because the project site is developed with existing athletic fields, and the project site does not contain significant mineral deposits, the project would not result in the loss of availability of a known mineral resource. No impact would occur.

11022 63 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project b) Would the project result in the loss of availability of a locally important mineral resource recovery site delineated on a local general plan, specific plan, or other land use plan?

See Section 3.11(a). No impact would occur regarding the loss of availability of a locally important mineral resource recovery site. 3.12 Noise

A site visit was conducted on April 30, 2018, to measure ambient sound levels in the project vicinity. The sound level measurement program included short-term (approximately 10- or 15- minute) measurements. Figure 7 shows the measurement locations (ST1, ST2, and ST3) marked on a site map and illustrates the proximity of existing residential land uses to the project site.

The project vicinity is occupied by existing residential, recreational, and educational uses. Existing noise sources affecting the noise environment in the project area include traffic noise from adjacent roadways and noise generated by existing residential land uses in the project vicinity.

Short-term (ST) measurements were conducted with a calibrated Rion NL-62 sound level meter placed on a tripod with the microphone positioned approximately 5 feet above the ground. The Rion NL-62 is a Type 1 precision sound level meter. Table 2 presents the results of the short- term noise measurements. Ambient sound level measurements and other data gathered during fieldwork is included in Appendix D.

The short-term measurement results varied depending on the nearby traffic. ST2 is located along

Fury Lane where the highest noise levels were measured at 60.5 dBA Leq. ST3 is located in the residential area south of the site and away from Fury Lane. The lowest noise levels were measured at this location at 52.4 dBA Leq. a) Would the project result in 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?

The project site is located in the Valle de Oro Community Plan area of San Diego County. Noise regulations established in the County Code of Regulatory Ordinance are applicable to the project and referenced (where applicable) in the analysis below.

The project would generate short-term noise during construction and long-term noise during operation. Sources of construction and operational noise, and typical and modeled noise levels, are described below.

Construction Noise

Section 36.408 of the County’s Code of Regulatory Ordinances sets forth limitations on hours of operation of construction equipment. Except for emergency work, it shall be unlawful for any person to operate, or cause to be operated, construction equipment between 7:00 p.m. and 7:00 a.m. or on a Sunday or a holiday.

Section 36.409 of the County’s Code of Regulatory Ordinances sets forth sound level limitations on construction equipment. Except for emergency work, it shall be unlawful for any person to operate construction equipment, or cause construction equipment to be operated, that exceeds an average sound level of 75 decibels for an 8-hour period between 7:00 a.m. and 7:00 p.m. when measured at the boundary line of the property where the noise source is located or on any occupied property where the noise is being received.

Construction of the project would generate noise that could expose nearby receptors to elevated noise levels that may disrupt communication and routine activities. The magnitude of the impact would depend on the type of construction activity, equipment, duration of the construction, distance between the noise source and receiver, and intervening structures.

Equipment that would be in operation during construction would include trencher, excavators, drill rig, carpentry tools, hand tools, lifts, and cranes. None of the equipment would produce high levels of impact-type noise (which would be generated by pile driving,

11022 67 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

for example). Typically, construction equipment operates in alternating cycles of full power and low power, producing average noise levels less than the maximum noise level. The average sound level of construction activity also depends on the amount of time that the equipment operates and the intensity of the construction activities during that time.

The typical noise levels for various pieces of construction equipment at a distance of 50 feet are presented in Table 3. For example, the measured maximum sound level from a backhoe is 78 dBA at a distance of 50 feet.

Table 3 Construction Equipment Noise Levels

Measured Lmax at 50 Feet Equipment Description Acoustical Use Factor (%) (dBA, slow) Compressor (air) 40 78 Crane 16 81 Dump truck 40 76 Excavator 40 81 Flat-bed truck 40 74 Front-end loader 40 79 Man lift 20 75 Paver 50 77 Pickup truck 40 75 Pneumatic tools 50 85 Warning horn 5 83 Welder/torch 40 74 Source: DOT 2006.

The FHWA Roadway Construction Noise Model (RCNM) (FHWA 2008) was used to estimate construction noise levels at the nearest existing noise-sensitive land uses. Although the model was funded and promulgated by the FHWA, the RCNM is often used for non- roadway projects because the same types of construction equipment used for roadway projects are also used for other project types. Input variables for the RCNM consist of the receiver/land use types, the equipment type and number of each (e.g., two graders, a loader, a tractor), the duty cycle for each piece of equipment (e.g., percentage the equipment typically works in a given time period), and the distance from the construction equipment/activity to the noise-sensitive receiver. No topographical or structural shielding was assumed in the modeling. The RCNM has default duty-cycle values for the various pieces of equipment, which were derived from an extensive study of typical construction activity patterns. Those default duty-cycle values were used for this noise analysis. Table 4 provides a summary of the assumed construction equipment used for the different phases of construction.

Table 4 Construction Equipment By Phase

Construction Phase Equipment Utility trenching Trencher Excavator Excavation of pole locations Drill rig Excavator Installation of concrete base Carpentry tools Assembly of luminaries and installation on poles Hand tools Forklift Installation of poles into concrete base Small crane

Using the FHWA RCNM construction noise model and construction information (types and number of construction equipment by phase), the estimated noise levels from construction were calculated for a representative range of distances, as presented in Table 5. Table 5 shows the results from the RCNM analysis conducted for the project. R1 represents a receiver approximately 10 feet from the nearest construction operations. This receiver analysis is intended to represent a worst case when construction operations are occurring near the site boundary with the existing residences adjacent to the project site. R2 represents the typical distance from construction activities to noise sensitive receivers of approximately 200 feet.

The RCNM inputs and outputs are provided in Appendix D.

Table 5 Construction Noise Modeling Summary Results

As presented in Table 5, the highest noise levels (97 dBA) are predicted to occur during the installation of the concrete base phase for the adjacent noise-sensitive land use. For the more typical source-receiver distance, the highest noise levels are also expected during the concrete

base installation phase, when typical noise levels would be approximately 71 dBA Leq.

11022 69 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

Average noise levels from construction activities may be annoying since levels are expected to be higher than the ambient noise levels in the site vicinity. Temporary increases in daytime noise levels from construction could approach 97 dB at the nearest noise- sensitive receptors; however, these levels are unlikely to be sustained over the workday and would fluctuate as activities start and stop and as workers and equipment move around the site. However, given the proximity of residential land uses to the project site and noise levels anticipated during construction, this analysis conservatively assumes that a potentially significant noise impact could occur during construction. Construction activities are anticipated to take place over a 2 month (or shorter) period and would generally occur between 7:00 a.m. and 3:30 p.m. Monday through Friday. The County’s Code of Regulator Ordinances limits construction activities to between 7:00 a.m. and 7:00 p.m., Monday through Saturday. Limiting construction activities to daytime hours would avoid noise impacts during evening and nighttime when most people are resting or sleeping. Further, the District would require the Contractor to implement measures and methods that would ensure compliance with the County Noise Ordinance’s average sound level limits. As such, temporary construction noise levels would not exceed levels established by the County’s Noise Ordinance and noise impacts during the daytime would be less than significant.

Operational Noise Section 36.404 of the County’s Code of Regulatory Ordinances sets forth general sound level limitations that are associated with the underlying zoning designation. As shown on Figure 4, Zoning, the closest residential land uses are located to the south and are zoned RU. In accordance with Section 36.404, the following 1-hour average sound level limits (dBA) are established for the RU zone:

 7:00 a.m. to 10:00 p.m.: 55 dBA  10:00 p.m. to 7:00 a.m.: 50 dBA

Section 36.404 also contains the following standards:

 If the measured ambient noise level exceeds the applicable limits [above] the allowable one-hour average sound level shall be the one-hour average ambient noise level, plus three decibels. The ambient noise level shall be measured when the alleged noise violation source is not operating.

The field is currently used on a daily basis. On weekdays, activities end at approximately 6:00 p.m. during standard daylight time and 8:30 p.m. during daylight savings time. On weekends, activities typically end at approximately 5:00 p.m. Facilities use permits are

11022 70 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

required for organizations that wish to use the field. Field use is anticipated to be similar upon completion of the project, with the exception that use would be extended to 8:30 p.m. on weekdays during standard daylight time. Field use is currently limited by darkness after sunset during this time of year, such that all uses ceases by no later than 6:00 p.m. Once lighting is installed, field use would be required to end no later than 8:30 p.m. The school district would install timers that would be programmed to shut off the lights at 8:30 p.m. The primary use of the field after school hours is for youth soccer leagues.

Once the project is operational, exterior noise levels from traffic are expected to be unchanged due to the project. While vehicles might leave later due to the extended use hours of the field, the average daily traffic is expected to remain unchanged. Thus, operational traffic noise impacts are expected to be less than significant. However, noise levels from events (specifically field games played later into the evening hours past sunset) could extend to later periods of the day once the project is complete.

Previous measurements of youth soccer games during a tournament show that typical noise

levels (Leq) from similar events are approximately 54 dBA at 100 feet from the center of field (Mikel 2010). The nearest residences are approximately 130 feet from the center of the soccer field and farther from the center of the baseball fields that would also be illuminated as part of the project. Thus, with the distance between the adjacent noise-sensitive receivers and game activities being greater than 100 feet, game noise levels from crowds and other

activities are expected to be less than 54 dBA Leq. This noise level is similar to the range of ambient noise levels measured on the site, which ranged from 52 to 60 dBA (shown in Table 2). Given the soccer and baseball fields presently exist and are regularly used, the increase over existing activity would be limited to the evening hours past sunset; this additional period would consist of no more than 2 hours and 30 minutes daily during times of the year when the sun sets earlier in the evening. Therefore, operational noise would not exceed the County standard for the RU zone (i.e., 55 dBA between 7:00 a.m. to 10:00 p.m.) during operations, and impacts would be less than significant. b) Would the project result in exposure of persons to or generation of excessive groundborne vibration or groundborne noise levels?

Construction activities that might expose persons to excessive groundborne vibration or groundborne noise have the potential to cause a significant impact. Groundborne vibration information related to construction/heavy equipment activities has been collected by the California Department of Transportation (Caltrans). Information from Caltrans indicates that transient vibrations (such as from demolition activity) with a peak

11022 71 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

particle velocity (PPV) of approximately 0.035 inches per second may be characterized as barely perceptible, and vibration levels of 0.24 inches per second may be characterized as distinctly perceptible (Caltrans 2013). Caltrans (2004) uses a damage threshold of 0.2 inches per second PPV for conventional buildings.

Groundborne vibration is typically attenuated over relatively short distances. At the nearest distance from an existing residence to the construction area (approximately 10 feet), and with the anticipated construction equipment, construction-related vibration levels would be approximately 0.095 inches per second PPV. This vibration would be above the threshold of “barely perceptible” level of 0.035 inches per second PPV. However, this vibration level is well below the distinctly perceptible level of 0.24 inches per second PPV (DOT 2006). The expected vibration level at the residential buildings is also expected to be below the Caltrans damage threshold for conventional buildings. Therefore, impacts related to groundborne vibration would be less than significant. c) Would the project result in a substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project?

Guidance regarding the determination of a substantial permanent increase in ambient noise levels in the project vicinity above existing levels is provided by the Federal Highway Administration (FHWA) and California Department of Transportation (Caltrans). In Title 23 Part 772 of the Code of Federal Regulations (23 CFR 772), a substantial noise increase for federally funded transportation projects is defined as a range (to be determined by each state’s transportation department) between 5 and 15 dBA above existing ambient levels. In the State of California, Caltrans defines a substantial noise increase as 12 dBA or more (Caltrans 2011). Because the project is located in California, the threshold of 12 dBA or more is used to define a substantial increase.

With the expected field noise levels similar to the measured existing ambient noise levels, and given the limited extended hours of use, the operational noise impact of the project would be expected to result in less than a 3 dBA increase in the ambient hourly Leq and CNEL in the area. With the expected change in the ambient noise levels (in terms of Leq and CNEL) less than a perceptible level change for an average person in an outdoor environment, the project would not result in a substantial permanent increase in ambient noise levels. Therefore, the increase in operational noise levels are considered less than significant.

11022 72 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project d) Would the project result in a substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels existing without the project?

Section 36.410 of the County’s Code of Regulatory Ordinances sets forth sound level limitations on impulsive noise. In addition to the general limitations on sound levels in Section 36.404 of the County’s Code of Regulatory Ordinances and the limitations on construction equipment in Section 36.409 of the County’s Code of Regulatory Ordinances, the following additional sound level limitations shall apply:

A. Except for emergency work or work on a public road project, no person shall produce or cause to be produced an impulsive noise that exceeds the maximum sound level shown in [Table 7 of Section 36.409], when measured at the boundary line of the property where the noise source is located or on any occupied property where the noise is received, for 25% of the minutes in the measurement period. The maximum sound level depends on the use being made of the occupied property.

For residential occupied land uses (such as those located to the south of the project site), the maximum allowable sound level (impulsive) measured at the property is 82 dBA.

Construction activities would result in a temporary increase in ambient noise levels. Specifically, temporary increases in daytime noise levels from construction could exceed 12 dB at the nearest noise-sensitive receptors. However, construction is expected to take place over a relatively brief duration and would generally occur during between 7:00 a.m. and 3:30 p.m. Monday through Friday. Limiting construction hours to only daytime hours would avoid noise impacts during evening and nighttime, when most people are resting or sleeping. Further, the District would require the Contractor to implement measures and methods that would ensure compliance with the County Noise Ordinance’s average sound level limits. Therefore, the Contractor would be required to ensure compliance with the County Noise Ordinance’s average sound level limits for construction and impacts associated with the temporary increase in ambient noise levels during construction would be less than significant. e) Would the project be 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?

The nearest active airport to the project site is Gillespie Field, located approximately 5.8 miles northwest of the project site. According to the Gillespie Field Airport Land Use

11022 73 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

Compatibility Plan (ALUCP), the project site is not within the noise exposure area or Airport Influence Area (ALUC 2010). Montgomery Field Airport is located approximately 12.7 miles to the northwest of the project site, and the San Diego International Airport is approximately 15 miles west of the project site. Due to distance from these airports, the project would not expose people residing or working in the project area to excessive noise levels. Therefore, no impact would occur. f) Would the project be within the vicinity of a private airstrip, would the project expose people residing or working in the project area to excessive noise levels?

The nearest private airstrip is the John Nichols Field, located approximately 8.3 miles southeast of the project site. The project site is not located near a private airstrip. Therefore, the project would not expose people residing or working in the project area to excessive noise levels, and no impact would occur.

3.13 Population and Housing a) Would the project induce substantial population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)?

The installation of field lighting at the project site would serve the existing school and surrounding community population and would not involve extension of utilities or services that would induce population growth. Therefore, the project would have a less than significant impact on population growth in the area. b) Would the project displace substantial numbers of existing housing, necessitating the construction of replacement housing elsewhere?

There is no existing housing on the project site. Existing athletics fields on the Hillsdale Middle School campus occupy the project site. Therefore, no housing would be displaced, and there would be no impact to existing housing. c) Would the project displace substantial numbers of people, necessitating the construction of replacement housing elsewhere?

The project site does not include any existing housing as it is developed with the existing Hillsdale Middle School athletics fields. No persons would be displaced by the project; therefore, there would be no impact necessitating the construction of replacement housing elsewhere.

11022 74 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

3.14 Public Services a) Would the project result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, 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?

Fire protection for the project site is provided by the San Miguel Consolidated Fire Protection District. The project would not generate population growth or add people to the area. Thus, the project would not generate the need for additional fire services that would require new or physically altered facilities. No impact to fire services would occur.

Police protection?

Police protection for the project site is provided by the County Sheriff’s Department. The project would not generate population growth or add people to the area. Thus, the project would not generate the need for additional police services that would require new or physically altered facilities. No impact to police services would occur.

Schools?

The project would install field lighting at athletics fields at Hillsdale Middle School. The project would serve the County’s existing population and would not induce population growth. Therefore, the project would not increase demand for schools or necessitate construction of new school facilities. No impact would occur.

Parks?

Other public facilities?

The project would install field lighting at athletics fields at Hillsdale Middle School. The project would serve the County’s existing population and would not induce population

11022 75 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

growth. Therefore, the project would not increase demand for other public facilities or services. No impact would occur. 3.15 Recreation a) Would the project increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated?

The project would install field lighting at athletics fields at Hillsdale Middle School. The project would serve the County’s existing population and would not induce population growth. However, new lighting installed at the athletic fields would facilitate nighttime use of the soccer/football field and baseball/softball fields. Nighttime use of fields would occur 7 days per week, and hours of operation would be until 8:30 p.m. Monday through Friday and until 5:00 p.m. on Saturday and Sunday. While the project would extend the hours of operation/use of the athletic fields throughout the week, regular and continued maintenance of the fields by District field maintenance staff would ensure that substantial deterioration of the fields would not occur or be accelerated. Therefore, impacts would be less than significant. b) Does the project include recreational facilities or require the construction or expansion of recreational facilities, which might have an adverse physical effect on the environment?

Please refer to Section 3.15(a). The project would not demolish existing recreational facilities and would not construct new or expand current recreational facilities. The project would install field lights on the existing Hillsdale Middle School athletic fields. The project does not include recreational facilities and would not require the construction or expansion of recreational facilities. Therefore, no impact would occur. 3.16 Transportation and Traffic a. Would the project conflict with an applicable plan, ordinance or policy establishing measures of effectiveness for the performance of the circulation system, taking into account all modes of transportation including mass transit and non-motorized travel and relevant components of the circulation system, including but not limited to intersections, streets, highways and freeways, pedestrian and bicycle paths, and mass transit?

Fury Lane, which occurs to the west of the project site, is classified as a 4.1A Major Road by the Valle de Oro Community Plan and supported 13,600 average daily trips (ADT) in 2013 (San Diego County 2011a; SANDAG 2013). According to the San Diego County Public Road Standards, this pertains to a level of service (LOS) A classification (San Diego County

11022 76 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

2012). Brabham Street, to the north of the project site, is a light collector with one continuous left turn lane and had a 2013 roadway volume of 10,200 ADT (SANDAG 2013). This pertains to a LOS D classification (San Diego County 2012). The Highway Capacity Manual methodology assigns an LOS grade to an intersection based on estimated delay at that intersection, with LOS A representing the shortest delay and LOS F representing the longest. LOS E and LOS F are generally considered significant levels of traffic delay.

Project construction activities associated with the installation of field lights would occur over a period of 2 months. During this period, the project would not require closure of any streets or interfere with vehicle, pedestrian, bicycle, or mass transit access. During project construction, vehicles would access athletics fields directly and would not be staged on the street. Due to the low number of workers required during construction (approximately 18 workers would be required during the 2-month construction period; see Table 1) and the hours of construction (7:00 a.m. to 3:30 p.m.), construction traffic would not substantially change the number vehicle trips on the surrounding roadway network. Therefore, project construction would not cause changes to vehicle LOS at any intersection, roadway segment, or freeway segment.

During operations, the extended hours of field use enabled by the proposed field lighting could result in additional trips in the local area to the athletics fields. However, because use of the fields is limited to sports leagues and is subject to a facilities use permit issued by the District, the increase in traffic would not be substantial. The project would not change the existing land use and would not cause a substantial change in trip generation compared to existing conditions. Because the project would not substantially change the number of vehicle trips on the surrounding roadway network, the project would not cause changes to vehicle LOS at any intersection, roadway segment, or freeway segment.

Because the project would not result in a substantial increase in traffic on local streets and would not impact an existing LOS standard or a travel demand measure, impacts related to conflicts with an applicable plan, ordinance, or policy establishing measures of effectiveness for the performance of the circulation system would be less than significant. b) Would the project conflict with an applicable congestion management program, including, but not limited to level of service standards and travel demand measures, or other standards established by the county congestion management agency for designated roads or highways?

Please refer to Section 3.16(a). The project would install field lighting at athletics fields at Hillsdale Middle School. The extended hours of field use enabled by the proposed field lighting could result in additional trips in the local area to the athletics fields. Use of the

11022 77 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

fields is limited to sports leagues and is subject to a facilities use permit issued by the District. Therefore, an increases in traffic associated with extended hours of operation/use would not be substantial, and impacts would be less than significant. c) Would the project result in a change in air traffic patterns, including either an increase in traffic levels or a change in location that results in substantial safety risks?

The nearest active airport to the project site is Gillespie Field, located approximately 5.8 miles northwest of the project site. According to the Gillespie Field Airport Land Use Compatibility Plan (ALUCP), the project site is not within the Airport Influence Area or within any safety hazard areas (ALUC 2010). Montgomery Field Airport is located approximately 12.7 miles to the northwest of the project site, and San Diego International Airport is approximately 15 miles west of the project site. Due to distance from these airports, the project would not result in safety risks due to a change in air traffic patterns. Therefore, no impact would occur. d) Would the project substantially increase hazards due to a design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)?

The project would install field lighting at athletics fields at Hillsdale Middle School. The project would not result in changes to or interfere with the County’s vehicular, bicycle, or pedestrian transportation system or increase hazards or incompatible uses. Therefore, there would be no impact regarding hazards due to a design feature or incompatible use. e) Would the project result in inadequate emergency access?

Regional access within the project area is provided by SR-94 through Campo Road, Jamacha Road/SR-54, and Jamacha Boulevard. Fury Lane, Willow Glen Drive, Steele Canyon Road, and Jamul Drive are also major roads within the project area. Fury Lane, which borders the project site on the west, is considered a major road from Jamacha Road to SR-54 and a collector road west to Avocado Boulevard (San Diego County 2011a). The project would not require closure of any streets and would not interfere with emergency access to the project site or surrounding area. During project construction, vehicles would access athletics fields directly and would not be staged on the street. Therefore, no impact related to interference with an adopted emergency response plan or emergency evacuation plan would occur.

11022 78 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project f) Would the project conflict with adopted policies, plans, or programs regarding public transit, bicycle, or pedestrian facilities, or otherwise decrease the performance or safety of such facilities?

The project would not result in changes to or interference with the County’s vehicular, bicycle, or pedestrian transportation system or conflict with adopted policies, plans or programs regarding transportation. The project would install field lighting at athletics fields at Hillsdale Middle School. Therefore, there would be no impact.

3.17 Tribal Cultural Resources a. Would the project cause a substantial adverse change in the significance of a tribal cultural resource, defined in Public Resources Code section 21074 as either a site, feature, place, cultural landscape that is geographically defined in terms of the size and scope of the landscape, sacred place, or object with cultural value to a California Native American tribe, and that is:

i. Listed or eligible for listing in the California Register of Historical Resources, or in a local register of historical resources as defined in Public Resources Code section 5020.1(k)?

Please refer to Section 3.5(a). As described in Section 3.5(a), two historic properties are located within the 1-mile search radius of the project site, and these properties would not be affected during construction or operation of the project. Further, as described in Section 3.5(b), Native American outreach conducted for the project did not identify any specific cultural resources in the project APE.

A search of the NAHC Sacred Lands File was requested by Dudek on April 26, 2018. The NAHC response (received April 27, 2018) failed to indicate the presence of Native American cultural places within the project area or the surrounding 1-mile records search area. Contact information for potentially interested Native American representatives was provided and Dudek mailed information request letters to the contacts listed in the NAHC response on May 2, 2018. As of June 19, 2018, one tribal contact response had been received.

On May 14, 2018, Resource Manager Ray Teran with the Viejas Band of Kumeyaay Indians responded and determined that the project area has cultural significance or ties to Viejas. While they have no additional information regarding sacred sites, they have requested to have a Kumeyaay cultural monitor present during ground disturbing activities, and requested updated information concerning

11022 79 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

discoveries and new developments for the project. The District will allow Viejas to have a monitor present during earth-disturbing activities. However, due to the prior disturbance of the project site during development of the existing athletic fields, the potential for construction activities to encounter or unearth previously unknown cultural artifacts, cremation sites, or human remains is low. In addition and as detailed in Section 3.12, Mitigation Measure CUL-1 would be implemented during construction in the event of an inadvertent discovery of archaeological resources to allow for assessment and evaluation of the resources. Mitigation Measure CUL-1 also contains protocol to be implemented should construction activities to uncover human remains. Due to the low potential for inadvertent discovery of unknown archaeological resources and because Mitigation Measure CUL-1 would be implement in the event of an inadvertent discovery of archaeological resources, additional monitoring would not be implemented by the District.

Therefore, impacts would be less than significant.

ii. A resource determined by the lead agency, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision (c) of Public Resources Code Section 5024.1. In applying the criteria set forth in subdivision (c) of Public Resource Code Section 5024.1, the lead agency shall consider the significance of the resource to a California Native American tribe.

Please refer to Section 3.17(a)(i). Impacts would be less than significant.

3.18 Utilities and Service Systems a) Would the project exceed wastewater treatment requirements of the applicable Regional Water Quality Control Board?

The project would install field lighting at athletics fields at Hillsdale Middle School. The project site would serve the County’s existing population and would continue to be served by the Spring Valley Sanitation District and San Diego Metropolitan System. The project would not produce wastewater and would not result in an increase of wastewater generation at the site. No impact would occur.

11022 80 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project b) Would the project require or result in the construction of new water or wastewater treatment facilities or expansion of existing facilities, the construction of which could cause significant environmental effects?

Otay Water District provides water supply and treatment services within the project area, including the project site. The project would install field lighting at athletics fields at Hillsdale Middle School. The project would not require water or produce wastewater. Therefore, there would be no impacts related to water or wastewater treatment facilities. c) Would the project require or result in the construction of new storm water drainage facilities or expansion of existing facilities, the construction of which could cause significant environmental effects?

The project site is located on the developed Hillsdale Middle School campus and is currently developed with the school’s existing athletics fields. As described in Section 3.9, Hydrology and Water Quality, the project would not substantially alter existing drainage patterns or cause increased runoff from the project site. Because the project would not substantially change the volume of runoff from the project site, the project would not create or contribute stormwater runoff that would exacerbate any existing deficiencies in the existing storm drain system or provide substantial additional sources of polluted runoff. Therefore, there would be no impacts related to stormwater drainage facilities. d) Would the project have sufficient water supplies available to serve the project from existing entitlements and resources, or are new or expanded entitlements needed?

As discussed in Section 3.18(b), Otay Water District provides potable water to the project site. The project would install field lighting at athletics fields at Hillsdale Middle School. The project (i.e., operation of field lighting) would not require new entitlements of water. Thus, the project would not result in a significant increase in water use at the site, and no new or expanded entitlements would be required. No impact would occur. e) Would the project result in a determination by the wastewater treatment provider, which serves or may serve the project that it has adequate capacity to serve the project’s projected demand in addition to the provider’s existing commitments?

As described in Sections 3.18(a) and (b), the project would install field lighting at the Hillsdale Middle School athletics fields and would not produce wastewater. As such, the project would not change the existing wastewater flow to local wastewater treatment plants. Therefore, no impact to wastewater treatment capacity would result from the project.

11022 81 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project f) Would the project be served by a landfill with sufficient permitted capacity to accommodate the project’s solid waste disposal needs?

Construction of the project would produce minimal quantities of solid waste during project construction. Operation of the project would not result in a substantial increase in solid waste generation from the project site and field use permits require permitees to properly dispose of their trash. Therefore, the amount of solid waste generated by the project would be similar to the amount of solid waste currently generated by the project site, and would not contribute substantial quantities of solid waste to a landfill. Therefore, solid waste impacts resulting from construction and operation of the project would be less than significant. g) Would the project comply with federal, state, and local statutes and regulations related to solid waste?

As described previously, the project would install field lighting and would produce minimal quantities of solid waste during project construction. The project would comply with federal, state, and local statutes and regulations related to solid waste during project construction and operation. Therefore, no impacts related to solid waste regulations would result with implementation of the project. 3.19 Mandatory Findings of Significance a) Does the project have the potential to degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal, or eliminate important examples of the major periods of California history or prehistory?

As described in Section 3.4(a), due to the severity of past disturbance associated with development of the athletic fields, ongoing active use of the fields and regular field maintenance activities, it is unlikely that special-status plants or animals occur on the project site. However, mature trees are present along the north, west and southern project site boundary and therefore, the District would comply with the Migratory Bird Treaty Act and other applicable regulations protecting nesting and migratory bird species during construction.

The project’s potential to degrade, threaten, or otherwise eliminate important historical or archaeological resources is analyzed in Section 3.5, Cultural Resources, and Section 3.17,

11022 82 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

Tribal Cultural Resources. The entire project APE has been developed as athletic fields, and the SCIC records search, a NAHC Sacred Lands File search, and Native American outreach did not identify any cultural resources in the project APE. As such, no known cultural resources would be impacted by the project and there is very low potential for the inadvertent discovery of cultural resources during ground-disturbing activities. Therefore, no further studies would be required. However, if previously unknown archaeological materials are uncovered during construction, potentially significant impacts to archaeological resources may occur. Mitigation Measure CUL-1 would be implemented if previously unknown archaeological materials are encountered during construction. With implementation of Mitigation Measure CUL-1, impacts to archaeological resources would be less than significant with mitigation incorporated.

Despite previous ground-disturbing activities that have occurred on site, the project area is considered to have cultural significance or ties to a local Native American tribe (i.e., the Viejas Band of Kumeyaay Indians). Therefore, construction activities could result in impacts to a tribal cultural resource. As described in Section 3, the potential for construction activities to encounter or unearth previously unknown cultural artifacts, cremation sites, or human remains is low due. In addition, Mitigation Measure CUL-1 would be implemented during construction in the event of an inadvertent discovery of archaeological resources to allow for assessment and evaluation of the resources. Mitigation Measure CUL-1 also contains protocol to be implemented should construction activities uncover human remains. Due to the low potential for inadvertent discovery of unknown archaeological resources and because Mitigation Measure CUL-1 would be implement in the event of an inadvertent discovery of archaeological resources, additional monitoring would not be implemented by the District. Thererfore, impacts to tribal cultural resources would be less than significant. b) Does the project have impacts that are individually limited, but cumulatively considerable? (“Cumulatively considerable” means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects)?

As analyzed in Section 3, the project would result in less-than-significant impacts or no impact to aesthetics, agriculture and forestry resources, air quality, biological resources, geology and soils, GHG emissions, hazardous materials, hydrology and water quality, land use and planning, mineral resources, population and housing, public services, recreation, transportation and traffic, tribal cultural resources, and utilities and service systems. Due to incorporation of the recommended mitigation measures, potentially

11022 83 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

significant impacts related to cultural resources (including paleontological resources), and noise would be reduced to a level below significance.

The project proposes the installation of field lighting at Hillsdale Middle School. All potential impacts associated with the construction activities would be short term and temporary in nature and would occur over an approximate 2-month period. Once installed, new lighting would facilitate nighttime use of the soccer/football field and baseball/softball fields and District-controlled timers would be installed and programmed to shut off the lights at 8:30 p.m. on weekdays and 5:00 p.m. on weekends (when seasonally needed).

As indicated in GCCCD Master Plan, a paved parking lot and community field are proposed to be constructed within the water easement along the eastern boundary of the Cuyamaca College campus adjacent to Fury Lane (GCCCD 2013). As proposed, the community field would be sized to accommodate soccer games and will include restrooms and lighting. Combined with the project, future lighting of the community field would result in increased nighttime lighting in the project area. However, both the project and the proposed community field would be located in a developed area of Rancho San Diego in which existing sources of nighttime lighting operate. In addition, lighting associated with the project would be limited and controlled by District-installed timers, and both project lighting and future lighting associated with the proposed community field would be subject to compliance with local policies including San Diego County Light Pollution Code. Among other requirements, the Valle de Oro Community Plan requires that outdoor lighting fixtures be shaded on top so that all light shines downward. In addition, the Light Pollution Code requires that Class I lighting above 4050 lumens and within Zone B to be fully shielded. Further, both sources of lighting would be directed downward onto athletic fields and would be shielded to minimize sky glow and light trespass onto adjacent properties.

As demonstrated in Section 3 and above, the project does not have impacts that are individually limited but cumulatively considerable. Impacts would be less than significant. c) Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly?

Direct and indirect environmental effects on human beings were analyzed in the following sections: aesthetics, air quality, geology and soils, hazards and hazardous materials, hydrology and water quality, land use and planning, noise, population and housing, and transportation and traffic. As found in discussion of each relevant section, all potential impacts to human beings would be less than significant or no impact.

11022 84 June 2018 Initial Study/Mitigated Negative Declaration Hillsdale Middle School Field Lighting Project

Potential impacts would occur over the approximate 2-month construction period and would consist of potential exposure of receptors to noise levels in excess of daytime standards established by the County of San Diego. However, the project would comply with applicable federal, state, and local policies and regulations (including the County Noise Ordinance). For example, the District require the Contractor to implement measures and methods that would ensure compliance with the County Noise Ordinance’s average sound level limits. As such, temporary construction noise levels would not exceed levels established by the County’s Noise Ordinance. As such, the project would not result in environmental effects that will cause substantial adverse effects on human beings and impact would be less than significant.

Pre Post Const. Post Mitigation Measure During Const. Mitigation Measure CUL-1: In the unlikely event that archaeological X District materials are identified in the area during earth moving activities, work /contractor should be temporary halted in the vicinity and archaeologists consulted. A qualified archaeologist should be retained to assess any unanticipated discovery and evaluation efforts of said resource for CRHR and NRHP listing if required. Should human remains be discovered, work will halt in that area and procedures set forth in the California Public Resources Code (Section 5097.98) and California Health and Safety Code (Section 7050.5) will be followed, beginning with notification to the County Coroner. If Native American remains are present, the County Coroner will contact the Native American Heritage Commission to designate a Most Likely Descendent, who will provide recommendations for the dignified disposition and treatment of the remains. Mitigation Measure CUL-2: Since the project is not anticipated to X X X Qualified exceed the County’s 2,500 cubic yard grading threshold within paleontologist undisturbed substratum or deeper bedrock with high or moderate potential, the applicant shall designate a standard monitor to observe all excavations into native, undisturbed sediments to watch for fossils per the County (2009) guidelines. The use of a standard monitor ensures the project is in compliance with Section 87.430 of the Grading Ordinance. If a fossil is recovered that is larger than 12 inches in any dimension, work must be halted in the area of discovery, the Department of Planning and Land Use Permit Compliance Coordinator notified, and a project paleontologist retained by the applicant to assess the significance of the find. If the project paleontologist determines the find to be significant, they shall determine the program for fossil salvage, which includes salvaging, cleaning, and curating the fossil(s), and documenting the find.
