PROJECT ANALYSIS

Project Summary

The Sierra Canyon School proposes the expansion of bleacher seating for the Athletic Field from the current 300 seats to 1,630 seats, a net increase of 1,330 seats. Maximum attendance would be a total of 1,680 players and spectators. The Project would not result in any changes to the use of the existing Athletic Field as authorized by CPC-2008-3537-CU, which allows for up to seven Varsity football home games per season (late August through early December), occurring between 7:00 PM and 10:00 PM on Friday evenings. The Project also includes a request to allow the sharing of 236 parking spaces located on the Upper Campus across De Soto Avenue from the Athletic Field. No protected trees would be impacted as part of the Project. The Project proposes grading quantities in the amount of 1,075 cubic yards of cut, 180 cubic yards of fill, 300 cubic yards to be removed and re-compacted, and 895 cubic yards of export.

Background

Sierra Canyon School owns multiple parcels with a total lot area of approximately 32-acres zoned A2-1, RA-1, RE11-1, and (T)RE11-1, located on Rinaldi Street and De Soto Avenue in Chatsworth. The Sierra Canyon School consists of: . the Lower Campus for grades early K through 6th, is comprised of six parcels of land located west of the Los Angeles County Flood Control Channel/Brown’s Creek.

. the Upper Campus for grades 7th through 12th, is comprised of five parcels of land located on the east side of De Soto Avenue.

. the Athletic Fields are comprised of four parcels of land located on the west side of De Soto Avenue and east of the Los Angeles County Flood Control Channel/Brown’s Creek.

All three facilities are located north of Rinaldi Street and are within 1,200 feet of each other. The subject site is located within a Hillside Area, an Equine Keeping Area, a Very High Fire Severity Zone, a High Wind Velocity Area, a Special Grading Area, and a Liquefaction Area. On Rinaldi Street, on the south side of the school, is a public equestrian trail and sidewalk between Independence Avenue to De Soto Avenue. Cars going to the Sierra Canyon Athletic Fields and Upper Campus can access the sites by driving north or south along De Soto Avenue and turning west into the Athletic Fields parking lots or turning east onto Rinaldi Street to access the Upper Campus. The Athletic Fields parking lots, provide a total of 90 parking spaces (Athletic Field Parking), are comprised of two lots including a 75-space parking lot abutting Rinaldi Street (Rinaldi Parking Lot) and a 15-space parking lot along De Soto Avenue (De Soto Parking Lot). The Rinaldi Parking Lot is used for short-term parking for drop-off and pick-up of Lower School students during the morning and early afternoon and Lower School parents may not park at the Athletic Fields parking lot after 4 pm. The Upper Campus parking lots provide a total of 236 parking spaces (Upper Campus Parking) and are comprised of three lots including a 50-space parking lot behind the gymnasium known as Parking Lot A; a 74-space parking lot under the classrooms known as Parking Lot B; and, a 112- space parking lot west of the classrooms known as Parking Lot C. Between the Athletic Field Parking and the Upper Campus Parking, Sierra Canyon provides approximately 326 parking spaces. When measured from lot line to lot line along the streets between the two sites, the distance between the Athletic Field and the Upper Campus is approximately 600 feet.

CPC-2019-627-CU-ZAD-SPR A-2

Sierra Canyon proposes to expand the number of bleacher seats for the Athletic Fields from the current 300 bleacher seats to 1,420 bleacher seats for the home team; and, add 210 bleacher seats for the visiting team. In total, the Athletic Fields would contain a total of 1,630 bleacher seats. The Athletic Fields were previously approved for 300 bleacher seats under CPC-2008- 3537-CU and reviewed through subsequent Plan Approvals. This project represents an expansion of this previously approved Conditional Use related to a private school. The additional bleacher seats are not considered floor area as defined by the Los Angeles Municipal Code. However, there are parking requirements associated with assembly seating. Table 1 below outlines the Project’s parking requirements. Table 1 – Project Vehicle Parking Parking Code Requirement Calculation Required Proposed Stadium 1 per five seats 1,630 seats / 5 seats 326 326 Total 326 326* * = Parking provided by shared parking of existing Sierra Canyon spaces

Properties located north of the subject property are zoned PF-1XL and improved with California State Route 118; properties to the west and south are zoned RA-1 and developed with single- family dwellings; and properties to the east across De Soto Avenue are zoned RE11-1, A2-1 and RA-1, and consist of a mix of single-family dwellings, vacant land and a Department of Water and Power (DWP) water storage facility.

De Soto Avenue is a Boulevard II dedicated to a width of 110 feet, and improved on the west side with sidewalk, curb and gutter.

Rinaldi Street is an Avenue I improved at the southerly boundary of the athletic field with a public horse trail and pedestrian sidewalk, but no through roadway. It is improved at the southerly boundary of the Lower School with a variable width, 75-foot to 109-foot right-of-way, and improved with roadway, curb and gutter, which terminates at the westerly property line of the athletic field, sidewalk and horse trail.

Independence Avenue is a Local Street dedicated to a width of 60 feet and a roadway width of 36 feet and terminates at Rinaldi Street.

Variel Avenue is a Local Street dedicated to a width of 60 feet with a 36-foot roadway.

Issues

Traffic

On May 26, 2019 the Los Angeles Department of Transportation (LADOT) reviewed an analysis prepared by Overland Traffic Consultants, dated May 2019, which found a net increase of 1,120 daily trips, and 453 p.m. peak hour trips, based on land use factors for the proposed numbers of seats. LADOT’s analysis concluded that the project would not result in significant impacts at any of the 9 intersections studied.

CPC-2019-627-CU-ZAD-SPR A-4

Attachment A to Exhibit D2 summarizing intersection-level Volume to Capacity Ratios and Levels of Service

Further, the potential effects on public rights-of-way and other transportation infrastructure resulting from the bleacher seats will be reduced in severity as the expanded bleacher seating is proposed to be utilized only for 5 home football games (and potentially 2 playoff games), as conditioned by this grant under Condition 4. The review by LADOT is attached as Exhibit D2.

As discussed at the public hearing on February 28, 2020, and further supplement by a letter from the applicant’s representative received March 6, 2020 and attached as part of Exhibit D5, the applicant will voluntarily make the following a part of their operations plan on game days:

• Provide crossing guards and traffic control officers at the Rinaldi/De-Soto Intersection for the Athletic Field driveway and at the Upper Campus parking lot driveways from 6 p.m. to 7:30 p.m. and from 9 p.m. to 10:30 p.m.

• Provide golf cart-type shuttles, or other means, to assist attendees with limited mobility to travel from the Upper Campus to the Athletic Field.

• Provide a location for ride-share drop-off and pick-up (Uber, Lyft, etc.).

CPC-2019-627-CU-ZAD-SPR A-5

Parking

The Upper Campus Parking has 236 parking spaces that are used primarily during school hours on weekdays and various hours on the weekends, whereas existing Athletic Field parking is 90 spaces. Sierra Canyon proposes to allow the use of the Upper Campus Parking for events at the Athletic Fields after school hours, not overlapping with the use of the school.

A Parking Demand/Shared Parking Study was prepared by Overland Traffic Consultants, Inc. for the proposed shared use of the Athletic Field Parking, Upper Campus Parking, and, if needed, street parking (attached as Exhibit D3). The study was conducted from Wednesday, November 13, 2019 to Tuesday, November 19, 2019 to identify typical parking demands for a week of operation. It found that peak parking demand for that period occurred at 2:00 p.m. on Thursday, November 14, 2019, with a parking surplus of 81 spaces between both parking areas. Observed peak demand from this study, combined with estimated peak demand during games resulted in a shortfall only during the 8:00 p.m. hour, and only of three (3) spaces. This observed and estimated peak demand would be mitigated through Condition 4 of this grant which limits the ability of other events and activities to take place during games.

The distance between the Athletic Field and the Upper Campus is approximately 600 feet. There are no reserved or restricted spaces in the parking areas. The Athletic Field Parking will continue to be used for parking during athletic events and drop-off/pick-up during school hours whereas the Upper School Parking would continue to be utilized as the required parking for that campus. During events at the Athletic Field, parents/guardians would have the option to use either parking lot. This grant would not affect the use of the parking spaces in the either area during school hours. There would also be no increase in student enrollment or operational changes of the Lower School or the athletic fields associated with this entitlement.

See above section for voluntary measures the applicant intends to implement to reduce Project externalities related to traffic and parking.

Noise and Lighting

A pair of issues raised at the public hearing on February 28, 2020, as well as in written comments submitted to the case file, related to the spillover effects of game-day noise and field lighting to adjacent neighbors. In its letter dated March 6, 2020 and attached as part of Exhibit D5, the applicant volunteered that no bands would play during game days. Further, the applicant’s representative stated at the public hearing that no new lighting would be part of the project. Additionally, the project has been conditioned to comply with the City Noise Ordinance, prohibit amplified speakers, and that any replacement for the existing lighting be designed and installed with shielding, such that the light source does not illuminate any adjacent properties, the public right-of-way, or the above night skies.

Entitlement Request

An issue raised at the public hearing was the sufficiency of the applicant’s request for a Conditional Use for the requested use (under LAMC 12.24 U.24), rather than a Plan Approval to modify the conditions of approval through the previous Conditional Use granted through Case Numbers CPC-2005-6118-VCU-SPR, CPC-2008-3537-CU, CPC-2015-2664-CU. Comments related to the athletic field as a valid Conditional Use request, as well as whether the applicant should have been required to file a Plan Approval to the prior grant rather than a new Conditional Use. As discussed in the applicant’s response to comments, submitted to the case file and attached in Exhibit D5, the school’s athletic field meets the definition of an accessory use to a school as defined in LAMC 12.03. While the use was previously approved as an accessory use

CPC-2019-627-CU-ZAD-SPR A-6 to a Conditional Use through prior cases, the extent of the increase in seating of greater than 20% necessitates a new Conditional Use approval.

Environmental Analysis

Another issue raised at the public hearing and through written comments was the sufficiency of a Class 14 Categorical Exemption as the environmental clearance for the Project. Class 14 Categorical Exemptions, as regulated in the California Code of Regulations Section 15314, consists of “minor additions to existing schools within existing school grounds where the addition does not increase original student capacity by more than 25% or ten classrooms, whichever is less. The addition of portable classrooms is included in this exemption.” As discussed above, athletic fields are a typical accessory use incidental to the operations of a school. As such, expansion of the athletic field seating is the expansion of an incidental use to the school use, and as the physical impacts are limited to the existing school grounds without increasing enrollment, the definition of the Categorical Exemption is met and the Project is thus exempt from CEQA. Supplemental comments in relation to the Project’s environmental analysis have been submitted by the applicant as part of Exhibit D5.

Conclusion

Based on the information submitted, the existing use on-site, and the fact that the project will not result in an increase in enrollment, the Department of City Planning recommends that the City Planning Commission approve the requested Conditional Use, Zoning Administrator’s Determination, and Site Plan Review for the expansion of bleacher seating and sharing of existing on-site parking resources. To maintain reduced impacts of the school on the surrounding community, conditions have been recommended to better coordinate the use and management of on-site parking spaces and to coordinate parking for special events. Such conditions are intended to reduce vehicular impacts on the surrounding area and support the continued efficiencies of the high school campus.

The proposed use is consistent with the site’s underlying zoning and the new construction will facilitate an upgrade to the high school’s athletic programming which is consistent with the ongoing use of the school. The additional seating will allow for enhanced extracurricular activities that will serve Sierra Canyon School’s existing and future student population, while the sharing of existing parking resources will limit off-site impacts on local streets. As such, the Planning Department is in support of the proposed improvement to the campus and recommends approval of the requested entitlements.

FINDINGS

CEQA FINDING

Based on the whole of the administrative record, as supported by the justification prepared and found in the environmental case file, the project is exempt from the California Environmental Quality Act (CEQA) pursuant to State CEQA Guidelines, Article 19, Section 15314, Class 14, and there is no substantial evidence demonstrating that any exceptions contained in Section 15300.2 of the State CEQA Guidelines regarding location, cumulative impacts, significant effects or unusual circumstances, scenic highways, or hazardous waste sites, or historical resources applies.

GENERAL PLAN/CHARTER FINDINGS

1. General Plan Land Use Designation.

The Property is located within the area covered by the Chatsworth-Porter Ranch Community Plan, updated and adopted by the City Council on September 4, 1993. The Plan designates the subject property as Very Low I Density Residential with corresponding zones of A2-1 and RA-1. The existing zoning is consistent with the land use designation of the General Plan as reflected in the adopted community plan.

2. General Plan Text.

The proposed location is recognized as being consistent with the various applicable elements and objectives of the General Plan, per prior approvals for the athletic field and bleachers, as well as the campus as a whole.

Overall, implementation of the Project would not detract from the valued visual character of the community or area; nor introduce inappropriate contrast between proposed Project elements and adjacent and nearby development; nor remove existing features that substantially contribute to the character of or image of the community; or nor be materially inconsistent with the goals and policies of the Chatsworth – Porter Ranch Community Plan.

The Project is the extension of an existing accessory use to an educational use that is compatible and consistent with the existing School and school-related athletic land uses in the vicinity. Structure heights would be consistent with the height of other existing structures in the Project vicinity. The Project site is separated from residential neighborhoods by distance, terrain, and by open space and other institutional uses in the vicinity. Therefore, the Project would not adversely change the existing relationships between numerous land uses or properties in an established neighborhood or community or have the long-term effect of adversely altering a neighborhood or community through ongoing disruption, diversion or isolation.

A stated goal of the Community Plan is "to encourage the preservation and enhancement of the varied and distinctive residential character of the Community." The proposed project is located adjacent to educational, public facility, and residential uses, with single-family homes located primarily south and east of the site. These adjacent uses have been thoroughly considered by the previous decision makers when designing the campus layout and school operation. School buildings, landscape treatments, and fencing have been sited to ensure the adequate screening and buffering of noise from exterior activity areas.

CPC-2019-627-CU-ZAD-SPR F-2

The Community Plan is intended to promote an arrangement of land use, circulation, and services which will:

Encourage and contribute to the economic, social and physical health, safety, welfare, and convenience of the Community; guide the development, betterment, and change of the Community to meet existing and anticipated needs and conditions; contribute to a healthful and pleasant environment; balance growth and stability; reflect economic potentialities and limitations, land development and other trends; and protect investment to the extent reasonable and feasible.

The proposed project will accomplish this by allowing Sierra Canyon School to further contribute to the operational, physical, and entertainment needs of their shared student body. The subject site will not only be available to the students and teachers of the two schools, but to the surrounding communities both directly through the applicant allowing the community to use the site for events and indirectly through the students who attend the schools and live in the surrounding communities. Finally, the proposed Project will not be detrimental to the character of development in the immediate neighborhood because the proposed athletic field and supporting facilities will be consistent with other institutional uses within the Community Plan.

3. Charter Findings.

Pursuant to Section 556 of the City Charter, the subject Conditional Use is in substantial conformance with the purposes, intent and provisions of the General Plan. The Los Angeles Municipal Code permits the filing, review, and determination of conditional use applications as outlined in Section 12.24. Provided findings of fact are made herein.

CONDITIONAL USE FINDINGS

4. The project will enhance the built environment in the surrounding neighborhood or will perform a function or provide a service that is essential or beneficial to the community, city, or region.

The Sierra Canyon School Athletic Fields were previously approved for 300 seats at the football field under CPC-2008-3537-CU. The instant request would represent an expansion of this use by 1,330 seats to a total of 1,630 seats. The school has previously demonstrated substantial compliance with the conditions of approval imposed in prior Conditional Use permits, including evidence that the school is operating near full capacity and providing essential educational services to both immediate residents and general residents of the San Fernando Valley.

Adjacent/proximate uses include Sierra Canyon Campuses to the west and east, single- family residences to the south and California State Route 118 to the north. The areas to the west and south are single-family residential. Properties across De Soto Avenue immediately to the east include a vacant parcel, two single-family homes fronting on Rinaldi Street, and Los Angeles Department of Water and Power land that includes a sunken reservoir. Most notably, Sierra Canyon Secondary School (grades 7-12) is on the north side of Rinaldi Street.

The north Chatsworth area, west of De Soto Avenue and east of Mason Avenue, is primarily designated for Very Low I Residential uses, corresponding to the RE20 (Residential Estate) and RA (Residential Agriculture) zones designated in the Chatsworth-Porter Ranch

CPC-2019-627-CU-ZAD-SPR F-3

Community Plan. The rural quality of the region is enhanced by the proximity of equestrian trails and some unpaved local streets. Within the north De Soto Avenue corridor, newer residential subdivisions are generally located east of De Soto Avenue, between De Soto and Mason Avenues, while horse-keeping properties are generally located west of De Soto Avenue. Since the 1970s, higher density single-family subdivisions have been built in lower density agricultural neighborhoods (formerly operating truck farms and small ranches) and new local streets were developed to serve these subdivisions. Porter Ranch, a community adjacent to SR-118, is largely built-out east of Corbin Avenue. More recently, development of more residential uses has extended west of Mason Avenue. The proposed use supports the educational and operational needs of Sierra Canyon.

The proposed Project will enhance the built environment in the surrounding neighborhood and will perform a function and a service that is beneficial to the community. The fields themselves and the events taking place thereon would not be expanded in scope or occurrence; rather, the Project represents an expansion of attendee seating and a more efficient use of parking resources to better serve the expanded seating. The improvement of the athletic fields would provide athletic facilities and general open space that would relieve any potential burden to City operated recreational facilities that would otherwise be used for School competitive athletic events. Further, the enhanced facilities do not represent an expansion in student enrollment; rather, the Project will serve to enhance extracurricular facilities for existing students, parents, and visitors.

Therefore, the continued use and proposed expansion of the existing school will provide a service that is both essential and beneficial to the community.

5. The project’s location, size, height, operations, and other significant features will be compatible with and will not adversely affect or further degrade adjacent properties, the surrounding neighborhoods, or the public health, welfare, and safety.

The location, size, height, operations and other significant features of the proposed Project will be compatible with and will not adversely affect or further degrade adjacent properties, the surrounding neighborhood, or the public health, welfare, and safety. The proposed expansion of bleacher seating does not represent a new use, but the expansion of an existing one. Events taking place on the enhanced fields would not be changed in type, timing, or number of occurrences. The project would allow the school to maintain and enhance its physical built environment and the services provided to the student body in a way that will not adversely affect or further degrade adjacent properties or surrounding neighborhoods. Improvement of the athletic fields will help to provide greater and enhanced educational experiences for Sierra Canyon's students, thereby enriching and benefiting the students, the City and the region as a whole.

For the reasons identified above, the project would be desirable to the public convenience and welfare. The Project is designed to protect the surrounding communities and neighborhoods while allowing a reasonable use of the subject site. The site, once developed, will be self-sustaining. Any events at this site will have a minimal impact on the surrounding communities.

6. The project substantially conforms to the purpose, intent, and provisions of the General Plan, the applicable community plan, and any specific plan.

CPC-2019-627-CU-ZAD-SPR F-4

LAMC requirements. Except for the entitlement described herein, the Project does not propose to deviate from any other LAMC requirements. The General Plan is comprised of the Framework Element, seven state-mandated elements, and four additional elements. The Framework Element establishes the broad overall policy and direction for the General Plan. The Mobility Plan 2035 provides the policy foundation for achieving a transportation system that balances the needs of all road users. The proposed project meets the following goals, objectives and programs of the Mobility Plan:

Policy 3.3 Land Use Access and Mix: Promote equitable land use decisions that result in fewer vehicle trips by providing greater proximity and access to jobs, destinations, and other neighborhood services.

Policy 3.9 Increased Network Access: Streets, alleys, stairways, and other public right-of- ways play an important role in the City's mobility system by facilitating better connectivity. Increased network access improves the mobility of travelers by breaking up long blocks and providing short-cuts that reduce the distance required to get from one point to another.

Policy 4.13 Parking and Land Use Management: Balance on-street and off street parking supply with other transportation and land use objectives. Parking in Los Angeles is a crucial but often overlooked element of the larger mobility system in the City and region at large, with significant implications for travel behavior as well as urban form ... When planning for parking-related needs, it is important to consider ways of effectively managing parking demand.

Program PK.1 Creative Parking Solutions: " ... to identify and implement creative strategies to resolve parking conflicts in areas with high-parking demand".

Program PK.12 Shared Off-Street Parking: Facilitate the shared utilization of privately owned off-street parking facilities.

Program S.3 Safe Routes to School: Although the Mobility Element discusses partnering with LAUSD, in the subject proposal working with Sierra Canyon School can achieve the same program goal "to calm traffic in communities surrounding all elementary, middle and high schools to maximize pedestrian and bicycle convenience and safety".

The Health and Wellness Element of the City’s General Plan is designed to elevate health as a priority for the City’s future growth and development. As a recreational use, this Project meets the following goals, objectives, and programs of the Health and Wellness Element:

Policy 2.5 Schools as centers of health and well-being: Support strategies that make schools centers of health and well-being by creating economic, environmental, social, and physical conditions in and around local schools that are safe, abundant in healthy goods and services, and offer opportunities for physical activity and recreation.

The Land Use Element of the City's General Plan divides the City into 35 Community Plan areas. The Chatsworth-Porter Ranch Community Plan designates the property for Very Low I Residential land uses with corresponding zones of RE20 and RA. The property is not in a Specific Plan Area.

The proposed project meets the following goals, objectives and programs of the Chatsworth- Porter Ranch Community Plan:

CPC-2019-627-CU-ZAD-SPR F-5

Objective 6: To make provisions for a circulation system coordinated with land uses and densities and adequate to accommodate traffic; and to encourage the expansion and improvement of public transportation service.

Objective 7: To encourage open space for recreational uses, and to promote the preservation of views, natural character and topography of mountainous parts of the Community for the enjoyment of both local residents and persons throughout the Los Angeles region.

The community plan is silent regarding shared parking agreements. The school received a conditional use permit in July of 2009 for the athletic field and a conditional use in 1982 establishing the school. The City Council found that the school/athletic field was designed in a manner that was compatible with the adjacent residential uses and it was in conformance with the General Plan. The proposed shared parking agreement does not include construction, expansion, or reduction in required parking and therefore substantially conforms to the purpose, intent and provisions of the General Plan and the Chatsworth- Porter Ranch Community Plan.

ZONING ADMINISTRATOR’S DETERMINATION FINDINGS

7. The project will enhance the built environment in the surrounding neighborhood or will perform a function or provide a service that is essential or beneficial to the community, city, or region.

Sierra Canyon is requesting a determination to permit the shared parking of the 236 parking spaces in the Upper Campus Parking during events at the Athletic Fields, while the Athletic Fields Parking would provide the remaining 90 parking spaces, for a total of 326 parking spaces available for event attendees.

The shared use of the Upper Campus Parking during the hours the Upper Campus is closed would provide the benefit of relieving any potential burden to City operated recreational facilities that would otherwise be used for school competitive athletic events. The shared parking would best utilize existing resources and activate the pedestrian streetscape by having students and parents/guardians walking to an event at the Athletic Fields, reinforcing activation of the school’s pathways.

CPC-2019-627-CU-ZAD-SPR F-6

8. The project’s location, size, height, operations, and other significant features will be compatible with and will not adversely affect or further degrade adjacent properties, the surrounding neighborhoods, or the public health, welfare, and safety.

A Parking Demand/Shared Parking Study was prepared by Overland Traffic Consultants, Inc. for the proposed shared use of the Athletic Field Parking, Upper Campus Parking, and, if needed, street parking (attached as Exhibit D2). The study was conducted from Wednesday, November 13, 2019 to Tuesday, November 19, 2019 to identify typical parking demands for a week of operation. It found that peak parking demand for that period occurred at 2:00 p.m. on Thursday, November 14, 2019, with a parking surplus of 81 spaces between both parking areas. Observed peak demand from this study, combined with estimated peak demand during games resulted in a shortfall only during the 8:00 p.m. hour, and only of three (3) spaces. This observed and estimated peak demand would be mitigated through Condition 4 of this grant which limits the ability of other events and activities to take place during games.

Approval of the request would allow drivers to have more options for parking and would reduce the use of local streets for parking. The shared parking between the Athletic Field and the Upper Campus would supplement (not replace or reduce) the parking required for the Upper Campus. The shared parking would not result in any change in the facilities, or permitted use of the property, and would not adversely affect or further degrade adjacent properties, the surrounding neighborhood, or the public health welfare and safety.

9. The project substantially conforms to the purpose, intent, and provisions of the General Plan, the applicable community plan, and any specific plan.

The General Plan is the City's roadmap for future growth and development. The General Plan Elements establish goals, policies, purposes, and programs that provide for the regulatory environment in managing the City, and for addressing environmental concerns and problems. The majority of the policies derived from these elements are in the form of LAMC requirements. Except for the entitlement described herein, the Project does not propose to deviate from any other LAMC requirements. The General Plan is comprised of the Framework Element, seven state-mandated elements, and four additional elements. The Framework Element establishes the broad overall policy and direction for the General Plan. The Mobility Plan 2035 provides the policy foundation for achieving a transportation system that balances the needs of all road users. The proposed project meets the following goals, objectives and programs of the Mobility Plan:

CPC-2019-627-CU-ZAD-SPR F-7

Program PK.1 Creative Parking Solutions: " ... to identify and implement creative strategies to resolve parking conflicts in areas with high-parking demand".

Program PK.12 Shared Off-Street Parking: Facilitate the shared utilization of privately owned off-street parking facilities.

The proposed project meets the following goals, objectives and programs of the Chatsworth- Porter Ranch Community Plan:

CPC-2019-627-CU-ZAD-SPR F-8

10. A total number of parking spaces will provide adequate parking for the uses on the site.

As previously stated, the required parking for the Project will remain in the Athletic Field Parking and Upper Campus Parking with 326 parking spaces. The shared use of the 326 parking spaces as requested would only be used during event hours after school. The Athletic Field is located approximately 600 feet from the Upper Campus, which is within the 750 feet required per LAMC Section 12.21.A 4(g). Typical school hours are from 8:30 am to 2:30/3:00 p.m. for all students in Sierra Canyon and the Athletic Field is used mostly after the Upper Campus is released (3:00 p.m.).

As stated above, a consultant conducted an analysis of the parking lot demand that found that the athletic field parking lot exceeded capacity during one hour and by a minor amount, which would be mitigated through appropriate conditions. Therefore, during the event hours, the 326 parking spaces would provide adequate parking for the Athletic Field.

SITE PLAN REVIEW FINDINGS

11. The project is in substantial conformance with the purposes, intent and provisions of the General Plan, applicable community plan, and any applicable specific plan.

CPC-2019-627-CU-ZAD-SPR F-9

with significant implications for travel behavior as well as urban form ... When planning for parking-related needs, it is important to consider ways of effectively managing parking demand.

Program PK.1 Creative Parking Solutions: " ... to identify and implement creative strategies to resolve parking conflicts in areas with high-parking demand".

Program PK.12 Shared Off-Street Parking: Facilitate the shared utilization of privately owned off-street parking facilities.

The proposed project meets the following goals, objectives and programs of the Chatsworth- Porter Ranch Community Plan:

The community plan is silent regarding shared parking agreements. The school received a conditional use permit in July of 2009 for the athletic field and a conditional use in 1982 establishing the school. On June 7, 2006, the City Council denied appeals and approved a conditional use for the Upper School at 20801 Rinaldi Street under case number CPC-2005- 6118-CU-SPR. Through these actions, the City Council found that the school/athletic field was designed in a manner that was compatible with the adjacent residential uses and in conformance with the General Plan. The proposed shared parking agreement does not include construction, expansion, or reduction in required parking and therefore substantially conforms to the purpose, intent and provisions of the General Plan and the Chatsworth- Porter Ranch Community Plan.

12. The project consists of an arrangement of buildings and structures (including height, bulk and setbacks), off-street parking facilities, loading areas, lighting, landscaping,

CPC-2019-627-CU-ZAD-SPR F-10

trash collection, and other such pertinent improvements, that is or will be compatible with existing and future development on adjacent properties and neighboring properties.

The Project would not provide any new buildings, off-street parking facilities, loading areas, trash collection, and other such pertinent improvements. Instead, the Project only proposes to provide additional bleachers for the school, which would be designed consistently with the overall appearance and character of the school buildings and their uses.

13. The residential project provides recreational and service amenities to improve habitability for its residents and minimize impacts on neighboring properties.

This finding is not applicable as the project contains no residential uses.

CPC-2019-627-CU-ZAD-SPR P-1

PUBLIC HEARING AND COMMUNICATIONS

The public hearing was held on February 28, 2020 at approximately 10:00 a.m. at Marvin Braude San Fernando Valley Consistent Service Center, 6262 N. Van Nuys Boulevard, Room 1B, Los Angeles, CA 91401. The hearing was conducted by the Hearing Officer, Andrew Jorgensen on behalf of the City Planning Commission in taking testimony for Case No. CPC-2019-627-CU-ZAD- SPR. All interested parties were invited to attend the public hearing at which they could listen, ask questions, or present testimony regarding the project. The purpose of the hearing was to obtain testimony from affected and/or interested parties regarding this application. Interested parties are also invited to submit written comments regarding the request prior to hearing. The hearing notice was mailed on February 4, 2020, published in the newspaper on February 3, 2020, and posted on-site on February 11, 2020, in accordance with Los Angeles Municipal Code noticing requirements.

The public hearing was attended by the applicant’s representative (Edgar Khalatian) and approximately four (4) other members from the applicant team, and approximately six (6) members from the community. Six (6) speaker cards were submitted for the hearing, including two (2) speaker cards in opposition of the project, two (2) in favor, and a representative from Council District No. 12. A letter of support was submitted to the case file from the Chatsworth Neighborhood Council.

Applicant Presentation

• The applicant provided a presentation which describes the Project, the instant entitlement request, and discussed technical studies. This presentation has been attached as part of Exhibit D5. • The ability to conduct games has already been granted through previous approvals. • The request is for the expansion of attendance, not the number of games. • Campus has 3 components – the Upper Campus, the Lower Campus, and the Athletic Fields; the Project does not include the Lower Campus. • Physical impacts limited to the Athletic Fields. • A shared parking analysis was conducted which justifies the shared parking request. • No events will occur concurrently with football games. • A press box will be installed. • Some California Sycamore trees, previously intentionally planted and thus not subject to the protected tree ordinance, will be replaced onsite. • No new lighting or speakers will be installed. • Analyzed shared parking at a ratio of 1 space for every 5 seats. • Limited mobility/special needs parking will be provided. • Security guards will be used to direct event attendees to park on-campus, rather than in the neighborhood. • Signage will also be provided.

Comments in Opposition of the Project:

• Jeanie Plumb, a resident of Chatsworth living on De Soto Avenue, provided comments in opposition to the Project: o CEQA Class 14 is an inadequate exemption; project bears no relation to student enrollment. o Full CEQA review is needed.

CPC-2019-627-CU-ZAD-SPR P-2

o Project is a facility and the request is a change in the operation of this facility, increasing seating by more than 400%. o Significant effects are triggered. o Current level of traffic congestion is a unique circumstance. o The entitlement request is faulty; should be an amendment to the existing CUP. o Request that conditions from prior approvals be included. o CPC-2008-3537 required filing of compliance reports; the first was filed, but the second never was, showing the school is out of compliance. • Clara Woll, a resident of Chatsworth living on Candice Place, provided comments in opposition to the Project: o Have several concerns, especially with traffic and pedestrian access. o Estimate based on the number of seats that approximately 1,180 people will be crossing De Soto Avenue to attend games. o The nearby intersection is the first south of the 118 Freeway. o Sidewalk and crosswalks are inadequate for the number of people crossing and will cause backup to/from the Freeway. o Request the inclusion of a railed, elevated staircase to prevent crossings of active driveways. o Signage should be put up when lots are full to discourage circling. o ADA parking at Athletic Fields is inadequate; should provide a full shuttle with phone number for use. o Parking provided is inadequate; neighborhood impacts will result. About 1/3 more spaces are needed if DOT rates 3.12 people per vehicle are used. o A new restroom building should be built at this time.

Comments in Support of the Project:

• Dan Huffman, a resident of Chatsworth living on Devonshire Boulevard, provided two comments in support of the project, one on behalf of the Chatsworth Neighborhood Council, and one on behalf of himself. o On behalf of Chatsworth Neighborhood Council: . Voted to support the request on June 5, 2019; letter submitted to case file. . Traffic, noise, lighting, parking, and safety were identified as issues. . The applicant’s representative addressed the Neighborhood Council’s concerns. . No games Sunday. . Portable restrooms will be provided. . Applicant will look for ways to improve traffic lighting/signaling. . Security staff will aid crossing before and after games. . A suggestion for a stop sign was looked at to replace a current yield sign, but there were concerns that this might cause traffic to back up. . Lighting should be downward pointing. . Meets required parking. . Dedicated rideshare parking and shuttles/golf carts should be provided. . Some public street parking is available. . No baseball games/practice at the same time as games. . The school is well regarded and provides a community asset; the expanded seating will allow for more family attendance to support student athletes. o On behalf of himself: . The request will serve students and community. . As a lifelong resident/neighborhood advocate have seen how well Sierra Canyon manages its parking and traffic planning.

CPC-2019-627-CU-ZAD-SPR P-3

. Sierra Canyon produces excellent students and athletes acting as a boon to the community. . Provides adequate seating for personal and family involvement. . Requests are appropriate and reasonable.

General Comments in relation to the Project:

• Martin Woll, a resident of Chatsworth living on Candice Place, provided general comments in relation to the Project: o LADOT conclusion/analysis is flawed. o Traffic impacts of 1,000+ pedestrians have not been considered. o Measured signal timing and pedestrian button stops traffic for 34 seconds. o 60 or so crossings would be required for attendees to walk from shared parking during rush hour. o De Soto/Chatsworth is graded an F intersection using Level of Service analysis. o Buses/shuttles are one solution. o Current hammerhead turnaround does fit buses. o A pedestrian underpass/overpass should be considered.

Council Office Comments:

• The following comments were provided by Council District 12: o Thanked Sierra Canyon for being a good community partner. o Thanked neighborhood stakeholders for taking the time to attend and share their valid concerns.

Applicant’s Response to Public Comments:

• The applicant’s representative provided the following comments in response: o There is no substantial evidence questioning the Categorical Exemption or the entitlement findings. o Not requesting to expand the number or type of events. o 7 sycamores to be removed, 1 live oak to be removed. o Intend to use golf carts to transport attendees with mobility needs. o Volunteered conditions include no activities conflicting with football games and to use crossing/security guards to direct attendees where to park and to aid in safe crossings.

WRITTEN CORRESPONDENCE

• In addition to written comments submitted on the day of the hearing mirroring the public comments summarized above, four letters were received after the hearing. All written comments are attached as Exhibit D5. • A letter was received from Scott Munson, with 27 signatories, expressing concerns with noise, provision of sufficient parking supply, whether the right entitlement request was filed, parking for event participants, overflow parking, technical aspects of the shared parking analysis, existing conditions of approval, sanitation, traffic, access, and sufficient CEQA analysis. • A letter was received from Martin Woll mirroring his comments at the hearing related to traffic impacts from pedestrian crossings. • A letter was received from Philip J. Hess, attorney for Jeanie Plumb, stating that the instant Conditional Use request is not the correct entitlement.

CPC-2019-627-CU-ZAD-SPR P-4

• A letter was received from the applicant’s representative offering voluntary conditions and responding to comments made at the public hearing.

JUSTIFICATION FOR PROJECT EXEMPTION CASE NO. ENV-2019-628-CE

Project Description:

Sierra Canyon School is proposing to add bleacher seats to the existing Athletic Field located in the Sierra Canyon School Athletic Complex is located at 11047–11055 North De Soto Avenue within the community of Chatsworth in the City of Los Angeles (City), directly south of State Route (SR) 118. The Athletic Complex currently contains a baseball field, football/soccer field (referred herein as “Athletic Field”), and other associated improvements as permitted by Condition Use Permit (CUP) CPC-2008-3537-CU. The existing Athletic Field includes approximately 300 bleacher seats along the eastern side of the field and a restroom facility. The existing Athletic Field also includes other features typical of a school football/soccer athletic field, including goal posts, light standards, scoreboard, and chain-link fencing.

The Athletic Field currently contains approximately 300 seats on the home (eastern) side of the Athletic Field. The Project would replace these existing seats on the home side with 1,420 seats and would add 210 seats on the visitor’s side, along the western side of the Athletic Field adjacent to Brown’s Canyon Wash. In total, these additions to the Athletic Field would contain 1,630 seats. The Project also includes the construction of a press box, egress stairs, retaining walls, and a decomposed granite path leading to the new visitor-side bleachers.

The Project would not result in any changes to the use of the existing Athletic Field as authorized by CPC-2008-3537-CU, which allows for up to seven varsity football home games per season (late August through early December), occurring between 7:00 PM and 10:00 PM on Friday evenings. Home team players would walk to the Athletic Field from the Upper Campus on the east side of De Soto Avenue for these games. The visitor’s team would arrive on a bus from their school. Each team would consist of approximately 25 persons. The maximum attendance for Friday night games would include a total of 1,680 players and spectators.

Parking for the existing Athletic Field would be provided by existing Parking Lot D near the Athletic Field. The Project also includes incorporation of a shared parking agreement that would provide for the shared use of 236 existing parking spaces located on the Upper Campus east of De Soto Avenue. As shown in Figure 3, parking on the Upper Campus is currently split between three lots: a 50-space parking lot behind the gymnasium known as Parking Lot A, a 74-space parking lot known as Parking Lot B; and a 112-space parking lot west of the classroom building known as Parking Lot C. Thus, the shared parking agreement would provide for a total of 326 parking on the Sierra Canyon School campus available for the athletic events currently permitted on the Project Site. ENV-2019-628-CE January 13, 2020

To enhance pedestrian and vehicle safety during athletic events, the Sierra Canyon High School would provide traffic control officers at the Athletic Field driveway (located on the west side of De Soto Avenue at Rinaldi Street) and Upper Campus driveways along Rinaldi Street during peak arrival and departure times on game days, likely from 6:00 PM to 7:30 PM and from 9:00 PM to 10:30 PM.

CEQA DETERMINATION – CLASS 14, CATEGORY 15300.2. CATEGORICAL EXEMPTION APPLIES

Class 14 consists of minor additions to existing schools within existing school grounds where the addition does not increase original student capacity by more than 25 percent or ten classrooms, whichever is less. The addition of portable classrooms is included in this exemption.

As a project involving approval of a Conditional Use Permit for the modification of conditions of approval under CPC-2005-6118-VCU-SPR and CPC-2008-3537-CU to allow the 1,630 bleacher seats; a determination to permit shared parking using the 236 parking spaces at the Upper Campus for the Athletic Field’s sports events by event attendees during the late afternoon and evening and a Site Plan Review due to the addition to an existing use, other than a Drive-Through Fast-food Establishment, which results in a net increase of 1,000 or more average daily trips as determined by the trip generation factors defined by the Department of Transportation to allow for a non-significant change of use in an existing facility, the project qualifies for a Categorical Exemption set forth at CEQA Guidelines, Sections 15314 and under City CEQA Guidelines, Article 3, Section 1, Class 14.

CEQA SECTION 15300.2 EXCEPTIONS TO THE USE OF CATEGORICAL EXEMPTIONS

The City has further considered whether the proposed project is subject to any of the six exceptions set forth in State CEQA Guidelines Section 15300.2, that would prohibit the use of any categorical exemption. None of the exceptions are triggered for the following reasons:

A. Location. Classes 3, 4, 5, 6, and 11 are qualified by consideration of where the project is to be located. A project that is ordinarily insignificant in its effect on the environment may in a particularly sensitive environment be significant. Therefore, these classes may not be utilized where the project may impact on an environmental resource of hazardous or critical concern where designated, precisely mapped, and officially adopted pursuant to law by federal, state, or local agencies.

This exception applies to Classes 3, 4, 5, 6 and 11 and not to Class 14, the Class applicable to this proposed Project. For this reason, this exception is not applicable

B. Cumulative Impact. The exception applies when, although a particular project may not have a significant impact, the impact of successive projects, of the same type, in the same place, over time is significant. The Project consists of modifications to the existing Sierra Canyon School Athletic Field with no increase or modification to the permitted uses. The shared parking agreement would not include the construction, expansion, or reduction in required parking on the existing campus.

The Project complies with the existing General Plan land uses and zoning designations for the site and permits issued for the facility. In addition, the Project promotes the City’s policies for promoting a mix of land uses and access; increasing network access; balancing parking and land use management; creating parking solutions; facilitating the shared utilization of privately owned off- street parking facilities; and promoting safe routes to school programs within the community. The Project would not adversely change the existing relationships among land uses or properties in the community; nor is the Project part of a series of successive projects of the same type in the immediate area that would result in significant impacts.

A ZIMAS case history search of properties within 1,000 feet of the Sierra Canyon Athletic Complex did not identify any requests for approval of modifications to an approved Conditional Use Permit, ENV-2019-628-CE January 13, 2020

or approval of a shared parking study, or a Site Plan Review for projects that would have the potential to result in cumulative impacts when considered with the proposed Project. The Traffic Impact Analysis for the Sierra Canyon Athletic Fields (Overland Traffic Consultants, May 3, 2019) includes analysis of potential cumulative traffic impacts from three related projects that have the potential to contribute traffic to the 3 intersections potentially affected by traffic generated by the proposed Project. The related projects considered in the traffic analysis include a 125 room hotel with 20,000 square feet of restaurant space at 9733 Mason Avenue, approximately 1.75 miles southeast of the Project Site, and 2 single family residential projects located north of SR 118 that include 193 and 314 units. These projects do not represent projects of the same type as the proposed Project. No significant cumulative traffic impacts were identified. Therefore, the impact of successive projects of the same type, in the same place, over time is less than significant.

C. Significant Effect Due To Unusual Circumstances. This exception applies when, although the project may otherwise be exempt, there is a reasonable possibility that the project will have a significant effect due to unusual circumstances. The Project consists of minor improvements to the existing Athletic Field located in the Sierra Canyon School Athletic Complex. The Project Site is not unusual in terms of size or other physical characteristics. There are no known unusual circumstances associated with the proposed Project or the Project Site. As described below no significant effects have been identified for the full range of environmental topics from the Initial Study Checklist.

Aesthetics The proposed Project site consists of minor Athletic Field improvements on an existing school campus, including the addition of bleacher seats, a press box, egress stairs, retaining walls, and a decomposed granite path. Implementation of the Project would not adversely affect the existing visual character of the community or area; introduce inappropriate contrast between proposed Project elements and adjacent and nearby development; or remove existing features that substantially contribute to the character of or image of the community. In addition, the design of the Project would complement the existing design of the school and associated athletic facilities, as well as the surrounding neighborhood. The Project would not introduce any new sources of light or glare. Therefore, the Project would not result in any significant aesthetic impacts.

Air Quality Construction Emissions - Air emissions that would be generated by construction activities were estimated based on the type and number of pieces of heavy construction equipment that would be used to: (1) replace the existing bleachers with two new bleachers to seat 1,420 spectators and 210 spectators, respectively; (2) press box and egress stairs installation; (3) retaining wall installation; (4) excavation and grading; and (5) decomposing granite path. Emissions calculations assumed that construction activities would be conducted in compliance with the South Coast Air Quality Management District (SCAQMD) rules pertaining to Fugitive Dust (Rule 403)1 and Architectural Coatings (Rule 1113),2 and that heavy-duty diesel equipment would meet minimum CARB off-road fleet requirements.

The analysis of daily construction emissions was prepared utilizing the California Emissions Estimator Model (CalEEMod) recommended by the SCAQMD. Table 1: Maximum Daily Construction Emissions presents the maximum estimated daily emissions anticipated to occur during Project construction. Emissions of volatile organic compounds, nitrogen oxides, carbon monoxide, sulfur oxides, and particulate matter are compared against the applicable SCAQMD mass daily thresholds of significance. As shown in Table 1, maximum daily emissions during construction would be below the applicable SCAQMD maximum daily emission thresholds. Accordingly, air quality emissions associated with construction of the Project would not have a significant effect on the environment.

Notes: Refer to Appendix A: Air Quality and Greenhouse Gas Background and Modeling Data. CO = carbon monoxide; NOx = nitrogen oxides; PM10 = particulate matter less than 10 microns; PM2.5 = particulate matter less than 2.5 microns; ROG = reactive organic gases; SOx = sulfur oxides.

Agricultural and Forestry Resources The surrounding area is an urbanized neighborhood along a major regional freeway. While a portion of the Project Site is zoned A2-1 (Agricultural Zone), the Project would not result in any changes to the existing uses currently permitted for the site under the CUP. The proposed Project does not contain any farmland or agricultural land that could potentially be impacted.

Biological Resources The Project Site is a fully improved site and does not contain any natural habitat of value for endangered, rare, or threatened species. In addition, the Project would not result in the removal, replacement, relocation, or impact to any trees on the Project Site. While the Project Site is adjacent to the Brown’s Canyon Wash, this portion of the wash is fully improved for flood control purposes and does not contain any natural riparian habitat. For these reasons, impacts would be less than significant.

Cultural Resources The Project Site does not contain any known cultural resources. The depth and extent of ground disturbing activities would be negligible. If subsurface cultural resources are inadvertently unearthed, the City has regulations on how artifacts found during construction must be handled. As such, no significant impacts to cultural resources would occur.

Geology and Soils The Project Site is not located within a State of California–identified Preliminary Fault Rupture Study Area. The Project Site is not located in a designated Earthquake Fault Zone.3 While the Project Site is located within a liquefaction zone as defined by the California Geological Survey,4 the proposed Project would be designed in accordance with the applicable California Building Code and applicable local codes. As such, the potential for hazardous events related to flooding, subsidence, slope instability, and seismic activity is considered low. Thus, the proposed Project would not result in any significant geology and soils impacts.

Greenhouse Gas Emissions Summaries of the greenhouse gas (GHG) emissions that would be generated construction of the Project are provided in Table 2: Project Greenhouse Gas Emissions. Total construction emissions would be approximately 31 metric tons of carbon dioxide equivalent (MTCO2e). Construction emissions amortized over 30 years would be approximately 1 MTCO2e/year.

The primary measure of whether a project would have an impact on GHG emissions is whether it would conflict with applicable regulatory plans and policies intended to reduce GHG emissions, in this case specifically the Southern California Association of Governments’ (SCAG) 2016–2040 Regional Transportation Plan/Sustainable Communities Strategy (2016 RTP/SCS). Key policies of SCAG’s 2016 RTP/SCS include improving access and mobility by encouraging efficient transportation infrastructure and pedestrian improvements. The Project is a field improvement project that would facilitate a more efficient use of existing school facilities to ensure travel safety and reliability for people in the region. As such, the Project would not have a significant impact on GHG emissions.

MTCO2e = metric tons of carbon dioxide equivalent. *N2O emissions are negligible.

Hazards and Hazardous Materials The Project would not involve the routine use, handling or transport of hazardous materials that would create a substantial risk to the public. The Project would not exacerbate hazardous conditions related to airports or wildland fires. Roadways used for emergency evacuation would not be obstructed. As such, impacts from hazards would not be significant.

Hydrology and Water Quality The portions of the Project Site that would be primarily affected by the Project is currently mostly impervious surfaces. The Project would be required to implement drainage measures that comply with the City’s regulatory requirements. The Project would also not place housing or residents within a flood zone. As such, impacts on hydrology would not be significant.

Land Use and Planning No alteration of street pattern is proposed, and no separation of existing uses or disruption of access would occur from the addition of seating to the existing Athletic Field. The Project Site is not located within a habitat conservation plan or natural community conservation plan. The Project would not result in any changes to existing uses on the Project Site as currently permitted by the CUP. Therefore, no significant land use or planning impacts would result from the Project.

Mineral Resources The Project area does not contain any known mineral resources, and the Project would not result in the loss of availability of a known mineral resource or locally important mineral resource recovery site. The Project Site is not located within an Oil Drilling/Surface Mining Supplemental Use District or an Oil Field/Drilling Area.5 Therefore, no impacts on mineral resources would occur.

Noise The Los Angeles Municipal Code (LAMC) section 41.40 regulates noise from demolition and construction activities. Exterior demolition and construction activities that generate noise are prohibited between the hours of 9:00 PM and 7:00 AM Monday through Friday, and between 6:00 PM and 8:00 AM on Saturday. Construction is prohibited on Sundays and all federal holidays.

Pursuant to the City Noise Ordinance (LAMC Section 112.05), construction noise levels are exempt from the 75-dBA noise threshold if all technically feasible noise attenuation measures are implemented. Pursuant to Section 112.05, the operation of any powered equipment or powered hand tool that produces a maximum noise level exceeding 75 dBA at a distance of 50 feet from the source of the noise is prohibited between the hours of 7:00 AM and 9:00 PM when the source is located within 500 feet of a residential zone. Compliance with Section 112.05 of the LAMC includes the use of mufflers, shields, sound barriers, and/or other noise reduction devices or techniques. All construction equipment, fixed or mobile, must be equipped with properly operating and maintained mufflers and other State-required noise attenuation devices. Additionally, equipment would be required to be shut down after 5 minutes of idling. Moreover, City Noise Ordinances 144,331 and 161,574 prohibit the emission or creation of noise beyond certain levels at adjacent uses unless technically infeasible. As such, no impacts from noise would occur.

Population and Housing The Project consists of minor Athletic Field improvements on an existing school campus. There be no change to the existing number of students and faculty on the campus. For this reason, the Project would not result in any substantial change in the number of employment opportunities or indirect population growth. Therefore, impacts on population and housing would be less than significant.

Public Services and Recreation Fire protection and emergency medical services to the Project Site would continue to be served by Los Angeles Fire Department (LAFD) Station 107, located at 20225 Devonshire Street, approximately 1.25 miles southeast of the Project Site. No changes to the permitted uses and no changes to access to the Athletic Field are proposed that would affect the ability of the LAFD to provide service to the site.

The Project Site is located within the area served by the Devonshire Community Station of the Los Angeles Police Department (LAPD). The Devonshire Division provides police protection services to the areas within the Canoga Park, Chatsworth, Granada Hills, Northridge, North Hills, Porter Ranch, West Hills, and Winnetka. The Devonshire Community Police Station is located at 10250 Etiwanda Avenue, approximately 3.5 miles southeast from the Project Site. No changes to the permitted uses and no changes to access to the Athletic Field are proposed that would affect the ability of the LAPD to provide service to the site.

The Project would not result in a substantial increase in demand for fire, police or other public services that would result in the need to construct new or physically altered facilities that could result in significant impacts.

Transportation The Traffic Report prepared for this Project (The Traffic Impact Analysis for the Sierra Canyon Athletic Fields (Overland Traffic Consultants, May 3, 2019) identified that the traffic conditions with implementation of the proposed Project would not impact the traffic flow at any of the study intersections in the Project vicinity. In addition, the traffic control officers that would be provided at the Athletic Field driveway and Upper Campus driveways during peak travel time would minimize on-street delays. The Project would also make no changes to or have direct effects on nearby transit services, roadways, or bicycle facilities. Roadway design and access would be equivalent to the existing network and would comply with City standards. As such, no significant impacts to transportation would occur.

Tribal Cultural Resources The Project Site does not contain any known cultural resources. The depth and extent of grading and excavation would be limited. If subsurface cultural resources are unearthed, the Project would comply with City regulations on how artifacts found during construction must be handled. As such, no significant impacts to tribal cultural resources occur. ENV-2019-628-CE January 13, 2020

Utilities and Service Systems The Project consists of minor Athletic Field improvements on an existing school campus. The proposed improvements would connect to the existing utility infrastructure that serves the Project Site. The Project would not result in an increase in demand for water, wastewater, solid waste, and energy demand from what is currently permitted on the Project Site under the CUP.

Wildfires While the Project Site is located in a State responsibility area classified as a Very High Fire Hazard Severity Zone,6 the minor improvements to the Athletic Field proposed would not result in any changes to the Athletic Field that would change or increase fire risks. In addition, no changes to the access to the Athletic Field are proposed that would affect the ability of the LAFD to access the site or affect the ability of students and visitors to exit the Athletic Field in the event of a fire event.

D. Scenic Highways. This exception applies when, although the project may otherwise be exempt, there may be damage to scenic resources, including but not limited to, trees, historic buildings, rock outcroppings, or similar resources, within a highway officially designated as a state scenic highway.

Based on a review of the California Scenic Highway Mapping System (http://www.dot.ca.gov/hq/LandArch/16_livability/ scenic highways/), the Project Site is adjacent to a segment of SR 118 designated as State scenic highway and appearing in Appendix B to the City’s General Plan Mobility Element, views of the Project Site are currently limited due to the substantial elevation change from the freeway. For this reason, the placement of the additional bleacher seats at the Athletic Field would not obstruct or adversely affect any existing views across the San Fernando Valley from SR 118. Accordingly, this exception does not apply.

E. Hazardous Waste Sites. Projects located on a site or facility listed pursuant to California Government Code 65962.5.

Based on a review of the California Department of Toxic Substances Control "Envirostor Database" (http://www.envirostor.dtsc.ca.gov/public/), no known hazardous waste sites are located on or proximate to the project site. In addition, the Project Site has been developed with school and associated Athletic Field uses since 1982. Based on this, the project will not result in a significant effect due hazardous waste and this exception does not apply.

F. Historical Resources. Projects that may cause a substantial adverse change in the significance of an historical resource. The Project Site does not contain any features that are listed or eligible for listing in the California Register of Historical Resources or in a local register of historical resources. The former structures that were on the site have previously been removed. Based on a review of HistoricPlacesLA, the nearest designated historic resource are the Stoney Point Outcroppings along Topanga Canyon Blvd, between Chatsworth Street and SR 118, which is designated as a Los Angeles Historic-Cultural Monument and is located approximately 0.6 miles west of the Project Site. Due to the nature of the Project, implementation of the Project would not result in any physical alteration to the nearby historic building and would not alter the context of the historic building. Therefore, the Project would not adversely affect the design, character, or feeling associated with any nearby historic resource. As such, this exception does not apply.

CONCLUSION

In conclusion, since the project meets all of the requirements of the categorical exemptions set forth at CEQA Guidelines, Sections 15314 and under City CEQA Guidelines, Article 3, Section 1, Class 14, and none of the applicable exceptions to the use of these exemptions apply to the project, it is appropriate to determine this project is categorically exempt from the requirements of CEQA.

EXECUTIVE SUMMARY

This report documents the results of a shared parking study for the proposed Sierra Canyon Athletic Field Bleacher seating expansion. The Sierra Canyon High School proposes to expand the current number of 300 bleacher seats to 1,420 bleacher seats for the home team and 210 bleacher seats for the visiting team (total 1,620 bleacher seats). Parking is proposed with 90 spaces in the Athletic Fields parking lot and 240 spaces located at the existing Sierra Canyon High School located at 20801 Rinaldi Street east of the Athletic Fields.

The focus of this parking study is to document the peak parking demand created by a Friday night home football game, determine the code parking required, and determine if the high school parking lots will provide sufficient space to accommodate the parking demand after school hours. To determine the actual peak parking demand during a football game, the City’s code requirements for assembly areas was used with anticipated hourly demand prior to a football game. The parking demand for the high school from 5:00 PM to 8:30 PM was determined based on physical counts of parked vehicles during Friday November 2, 2018 when no event was taking place at the school after hours.

Peak Parking Demand

The peak hourly parking demand for after school Sierra Canyon High School and Friday night Varsity Football Games has been added together in a shared parking model to estimate the overall parking demand. The results of the shared parking model show a peak parking demand of 336 parking spaces occurring between 7:30 and 8:30 PM.

Parking Supply

A total of 90 parking spaces are provided at the Athletic Fields parking lot, a total of 240 parking spaces are provided at Sierra Canyon High School, and a total of 37 to 50 legal

parking spaces are provided along Rinaldi Street’s High School frontage on the north side of the street and west of De Soto Avenue on the south side of the street. A combined total of 367 to 380 parking spaces are available during Friday night Varsity Football games.

Shared Parking Findings

Sufficient parking is provided to meet or exceed anticipated parking demand for Sierra Canyon High School after school hours and a Friday night Varsity Football Game.

No parking impact are anticipated with the Project.

SECTION 1 INTRODUCTION

Sierra Canyon High School has Athletic Fields provided on the north west corner of Rinaldi Street and De Soto Avenue. Athletes walk to/from the High School for practices and games. The existing Sierra Canyon Athletic Fields provide 300 bleacher seats at the football field. Currently, practices, Freshman (Frosh) and Junior Varsity (JV) games are held at the football fields during the school’s football season. Sierra Canyon High School would like to expand the number of seats from 300 bleacher seats to 1,420 bleacher seats for the home team and 210 bleacher seats for the visiting team (total 1,620 bleacher seats) in order to host home Varsity Football games. This would be the use that creates the greatest number of spectators. The following report presents the analysis of the parking supply and projected peak parking demands to ensure that the expansion of the amount of bleacher seating spaces at the Sierra Canyon Athletic Fields provides sufficient parking to accommodate the parking demand during a Varsity Football Game and still accommodate after school hours parking at Sierra Canyon High School.

Parking is currently provided with 90 spaces in the Athletic Field’s parking lot. There are 240 parking spaces at the existing Sierra Canyon High School located at 20801 Rinaldi Street east of the Athletic Fields. The High School parking areas would be used along with the Athletic Fields parking for the Varsity Home games providing a total of 330 parking spaces. In addition, 37 to 50 pubic parking spaces are available along Rinaldi Street along the school frontage on the north side of the street and east of DeSoto Avenue along the south side of the street. Home games would occur from 7:00 PM to 9:30 PM on seven Fridays per year between late August and early December. No other school events will be scheduled on the same day and time as these evening football games.

The location of the project site is shown in Figure 1. Figure 2 displays the current Sierra Canyon Athletic Fields and High School. This provides a visual display of the distance between the two properties. Sierra Canyon Athletic Fields 3 January 2019 Shared Parking Study Introduction

Figure 2 – Sierra Canyon Fields and High School

Parking availability on-site is as follows:  Behind Gymnasium, Parking Lot A has 56 parking spaces and a 120-foot loading zone.  Under the Classroom Building, Parking Lot B, there are 77 parking spaces.  West of the Classroom Building, Parking Lot C, there are 107 parking spaces.  Athletic Field, Parking Lot D, has 90 parking spaces.

A total of 330 parking spaces with 240 parking spaces at the school and 90 parking spaces at the Athletic Fields are available. Note that on-street public parking is also permitted with approximately 601 feet available on the north side of Rinaldi Street along the High School frontage and 158 feet available on the south side of Rinaldi Street

immediately east of De Soto Avenue. This adds and additional 37 to 50 parking spaces (dependent on spacing) in the vicinity of the Athletic Fields. This would not be for the exclusive use of the High School and available for public parking. However, it is apparent that this parking is not readily used other than by the school.

The concept site plan for the football field’s bleacher seating expansion is illustrated in Figure 3.

SECTION 2 CITY CODE PARKING REQUIREMENTS

City parking requirements for the Athletic Fields seating have been calculated by the applying the zoning code per Section 12.21 A. 4. (e & f). The code states that a high school stadium is required to provide one parking space per 35 square feet or one per 5 fixed seats. Upon completion, the Athletic Fields will provide project will provide 1,630 bleacher seats. As shown below in Table 1, a total of 326 parking spaces has been determined based on full occupancy of the seats.

Table 1 City of Los Angeles Code Parking Requirements

Parking Land UseSize Parking Requirement Required Bleacher Seating 1,630 seats 1 per 35 sf or 1 per 5 seats 326

The parking for the Athletic Fields football game will be provided on site with 90 spaces and at the Sierra Canyon High School that has 240 parking spaces. When the school parking lots are not in use, a total of 330 off street parking spaces would be available for Friday night Varsity football games. This is 4 spaces over the required number of parking spaces.

SECTION 3 SHARED PARKING DEMAND ANALYSIS

As stated previously, to determine the availability to park on the Sierra Canyon High School parking lots during games, the physical parking demand for the High School was determined and the individual hourly demand on a Friday game night was determined to evaluate the opportunity for the Athletic Fields to share the High School’s parking lots. Estimating the overall parking demand for the High School and Athletic Field Friday game night parking demand simply by adding the peak parking demand for the two uses produces an estimate that is too high. By adding each individual peak together, even though they occur at different times of day, creates an overabundance of parking.

The concept for shared parking is that a single parking space can be used to serve two or more uses without conflict since their parking demand differs throughout the day. A shared parking analysis shows that combining compatible land uses, such as the school use and evening football games, results in less parking demand. A Zoning Administrator may, upon application, permit two or more uses to share their off-street parking spaces, if the Zoning Administrator determines that a lower total number of parking spaces than would otherwise be required will provide adequate parking for these uses.

Peak parking demands differ between the High School and Athletic Field. This occurs because the parking demand for the High School parking peaks in the morning through the afternoon but the Athletic Field Friday Night game peaks at 7:30 PM. The current parking demand at Sierra Canyon High School from 5PM to 8:30 PM was determined based on physical counts on Friday, November 2, 2018 when no events were scheduled. This data, along with a parking supply inventory, is available in Attachment A. The estimated parking demand for the Athletic Field when a Varsity Friday night game is scheduled was based on estimated arrival and departure patterns. The hourly parking demand before, during and after a Friday night Varsity Football game 5:00 PM to 10:00 PM were then added to determine the adequacy of the parking supply.

It is estimated that 80% of those attending the Varsity Football game (typically running between 7:30 PM and 9:30 PM) will arrive between 6:30 PM and 7:30 PM. It is further estimated that 15% will arrive prior to 6:30 PM and 5% will arrive after the start of the game between 7:30 and 8:00 PM. Although some may occur, conservatively no departure was estimated between the start of the game through 8:30 PM. It was then estimated that 10% would leave prior to end of game between 8:30 PM and 9:30 PM with the balance, 90%, departing between 9:00 PM and 10:00 PM. The number of vehicles parked, hourly, for the Friday Varsity Football games was estimated using the hourly arrival and departure and City Code required parking of 326 parking spaces, at full occupancy

Table 3 displays the estimated percentage of peak demand hourly for arrival and departure of the Friday football games and the number of cars that will be parked hourly.

model to estimate the overall parking demand. The results of the shared parking model are shown in Table 5 for a Friday Varsity Football Game night. This table shows a peak parking demand of 336 parking spaces between 7:30 to 8:30 PM. This would create a deficiency of 6 vehicle spaces for off street parking.

Parking demand was counted at School between 5:00 PM to 8:30 PM when Athletic Field Demand would start to dissipate Conservatively Estimated with 10 parked cars at school between 8:30 to 10:30

As shown in Table 4, there is a potential for 10 vehicles to still be parked at the school during after hours without a football game in progress. This parking demand creates a deficiency of 6 off-street parking spaces to accommodate the combined parking demand. However, as mentioned previously, there is ample on-street parking near the school and athletic fields. Parking is permitted on the north side of Rinaldi Street along the bulk of the school frontage (601 feet). There is also parking permitted along the south side of Rinaldi Street from east of De Soto Avenue to 158 feet easterly. With an estimate space of 20 feet to 15 feet for each car, this would allow for 30 to 40 cars to be parked along the school frontage and 7 to 10 cars to be parked along the south side of Rinaldi Street. Rinaldi Street

on-street parking allows for an additional 37 to 50 vehicles to park. An evaluation of the number of vehicles parking along this public street parking between 5:00 PM to 8:50 PM was conducted on the same days as the school parking demand counts. Table 5 displays the combined parking demand for the Athletic Field, the High School, and on street parking along Rinaldi Street during a Friday night football game at the Athletic Field. Note that no vehicles were observed parked along Rinaldi Street in this area between 5PM and 8:30 PM.

Parking demand was counted at School between 5:00 PM to 8:30 PM when Athletic Field Demand would start to dissipate Conservatively Estimated with 10 parked cars at school between 8:30 to 10:30

As shown in Table 5, it appears that the on-street parking along the school frontage and along the south side of Rinaldi east of DeSoto is not needed by the school or surrounding community in the evenings. With this public on-street parking, conservatively estimated at the lower range with less than optimal parking spacing, sufficient parking is available for peak parking demand for a Friday night Varsity Football game with the High School residual after school demand with 31 spaces to spare during the peak period.

RE: Supplemental Parking Demand Evaluation for Sierra Canyon School Athletic Fields Bleacher Seating Increase Dear Mr. Jorgensen,

As requested by the City of Los Angeles Department of City Planning, Overland Traffic Consultants conducted a parking demand analysis for 24 hours per day for seven consecutive days for the Sierra Canyon Middle and Upper School (the “Upper Campus”), located at 11047 N. De Soto Avenue, Chatsworth, and its Athletic Field, located on De Soto Avenue at the terminus of Rinaldi Street. This demand analysis (“Supplemental Parking Demand Evaluation”) has been completed to supplement the previously submitted Shared Parking Study for the Sierra Canyon Athletic Fields Seating Project dated March 2019 (“Shared Parking Study”).

Background

The City previously approved Sierra Canyon to use its Athletic Field without limit on Mondays through Friday from 8:00 AM to 6:00 PM, up to five Friday night uses from 6:00 PM to 10:00 PM per calendar year1, and up to five night uses for any day of the week from 6:00 PM to 10:00 PM per calendar year.

Sierra Canyon currently proposes to increase the bleacher seats at the Athletic Field from 300 seats to 1,630 bleacher sets of which 1,420 seats are for the home team and 210 seats are for the visiting team. The Shared Parking Study was conducted to document the peak parking demand created by a Friday night "at-home" football game, to determine the code parking required, and to determine if the parking lots would provide sufficient space to accommodate the parking demand for these “at-home” football games. The peak hourly parking demand for the Upper School and Friday night football games were then added together in a shared parking model to estimate the overall parking demand.

1 An additional two Friday night uses are allowed from 6:00 PM to 10:00 PM per year for official football play-off games, if applicable.

Letter to Department of City Planning Overland Traffic Consultants, Inc. December 20, 2019 Page 2

The Shared Parking Study’s results for the shared parking model show a peak parking demand of 328 to 336 parking spaces occurring between 7:30 and 8:30 PM.

LAMC Section 12.21-A.4(e) requires one parking space for every five seats. Here, the City would require at least 326 parking spaces for the proposed 1,630 bleacher seats. The Athletic Field’s parking lot provides 90 parking spaces and the Upper Campus’s parking lots provide a total of 236 parking spaces, which provide a combined supply of 326 parking spaces. The Shared Parking Study concluded that there is sufficient parking provided and available to meet the anticipated parking demand for the Upper School for the Friday night football games.

Methodology

This Supplemental Parking Demand Evaluation is based on data collected using video and metered monitoring at the two Upper Campus driveways and the Athletic Field driveway for 24 hours per day for seven consecutive days. The number of vehicles entering and exiting the driveways were counted from Wednesday, November 13, 2019, to Tuesday, November 19, 2019, and this data is provided in Attachment 1.

The number of cars parked at the Upper Campus and the Athletic Field parking lots was determined hourly by subtracting the number of vehicles leaving the site from the number of vehicles accumulated on the site. For example, at the beginning of the day (hour 1) if two cars entered the site and one left then there would be a parking demand for 1 vehicle at the end of that hour. During hour 2, if three more cars entered and two left, there would be an accumulated parking demand for two vehicles (1 parked car from hour 1 + 3 cars entering – 2 cars leaving = 2 parked cars). Other than security personnel conducting security checks, the Upper Campus and Athletic Field parking lots were empty at midnight. In order to not have data showing negative demand and to have 0 vehicles at midnight, a “seed” number of cars was occasionally needed to determine the hourly parking demand. The hourly parking demand for the week, as determined from the Upper Campus Main Driveway, from the Secondary Upper Campus Driveway and from the Athletic Field Driveway, is presented in Attachment 2.

The parking demand, as presented in Attachment 2, was combined for each of the three driveways to determine the overall parking demand (the “Parking Demand”).

Data Collected

The Parking Demand shows the school’s parking demand for a typical week of operation. This includes a Junior-class college night on Wednesday, November 13th at 6:30 PM with approximately 200 people in attendance; volleyball playoffs on Thursday, November 14th at 6:00 PM with approximately 250 people in attendance; an admissions open house on Saturday, November 16th at 9:00 AM with approximately 400 people in attendance; and volleyball playoffs on Saturday, November 16th at 6:00 PM with approximately 250 people in attendance. Table 1, below, presents the week’s peak parking demand for each day, the time the peak parking demand occurred, and the number of surplus parking spaces.

The parking supply was short three spaces at 8:00 PM. At all other times on Friday night, the parking supply proved to be more than sufficient. When Sierra Canyon hosts a football game, it will not schedule any other activities on-site, so during the football games, the parking spaces will be used exclusively by those attending the football game. Therefore, the three vehicles that were parked on the school property when the counts were taken would not be parked on the school property during a football game and thus, there will be sufficient parking during football games.

Please contact me if you have any questions.

Sincerely,

Liz Fleming

Re: Athletic Field Improvement Project, Sierra Canyon School 20801 West Rinaldi Street, Chatsworth, California 91311

EXECUTIVE SUMMARY

This tree report was prepared in accordance with the City of Los Angeles Tree Preservation Ordinance No. 177,404 (Chapter IV, Article 6 of the Los Angeles Municipal Code, the "Ordinance") and the City’s Planning Division requirements. The Ordinance defines “protected” trees as coast live oak, western sycamore, Southern California black walnut, or California bay laurel with trunk diameters (measured at 4.5 feet above grade) of 4 inches or greater but this definition does not include (i) any tree grown or held for sale by a licensed nursery, or (ii) trees planted or grown as part of a tree planting program. “Significant” trees are any tree with a trunk diameter of 8 inches or larger.

We inventoried seven California sycamores and one coast live oak in or adjacent to the proposed site improvement area. We have determined through historic aerial imagery that these trees were intentionally planted as part of Sierra Canyon School's tree planting program and are therefore not protected by the City’s Ordinance (see pp. 7-8). All of the sycamores will be removed to accommodate the construction of the proposed site improvements. The single coast live oak will be preserved in place. There are no rights-of-way trees associated with the project.

BACKGROUND AND ASSIGNMENT

Sierra Canyon School is proposing new bleachers and other site improvements to the southwest portion of the existing football field. The eight inventoried private property trees are located on the western portion of the property on the southwest portion of the football field. We were retained to evaluate any trees considered “protected” or “significant” within and adjacent to the area of improvements (see Figure 1), and prepare a Protected Tree Report in accordance with the City’s ordinance. We visited the property, identified and inventoried all protected and significant trees meeting the trunk measurement thresholds. This report is based on our site visit on August 7, 2019.

Fig. 1 Highlighted zone of improvements

OBSERVATIONS AND DISCUSSION

Seven California sycamore trees were inventoried within the zone of improvements and one coast live oak located immediately outside of the area of improvements. Tree trunks were recorded in the field, from grade, and mapped on a Zimas aerial image. All trees were evaluated from the ground, without invasive testing, root crown examination, or any other form of advanced inspection. Captioned photographs and exhibits at the conclusion of this report illustrate site context, tree locations, tree structure, and vigor.

Table 1 is a summary of the tree species comprising the eight trees. Tree locations are graphically represented on the ‘Tree Location Exhibit’. The impacted trees are represented in the Tree Impact Exhibit.

CONCLUSION

There are eight private property trees within and near the zone of improvements. All seven California sycamores will need to be removed to accommodate the proposed site improvements. The coast live oak (tree #8) is outside of the zone of improvements and will be preserved in place. These trees were planted sometime during 2013-4 and are therefore not considered protected by the City’s ordinance.

HEALTH AND STRUCTURE GRADE DEFINITIONS

Health and structure ratings of the trees are based on the archetype tree of the same species through a subjective evaluation of its physiological health, aesthetic quality, and structural integrity.

Overall physiological condition (health) and structural condition were rated A-F:

Health

A. Outstanding – Exceptional trees of good growth form and vigor for their age class; exhibiting very good to excellent health as evidenced by normal to exceptional shoot growth during current season, good bud development and leaf color, lack of leaf, twig or branch dieback throughout the crown, and the absence of decay, bleeding, or cankers. Common leaf and/or twig pests may be noted at very minor levels. B. Above average – Good to very good trees that exhibit minor necrotic or physiological symptoms of stress and/or disease; shoot growth is less than reasonably expected, leaf color is less than optimal in some areas, the crown may be thinning, minor levels of leaf, twig, and branch dieback may be present, and minor areas of decay, bleeding, or cankers may be manifesting. Minor amounts of epicormic growth may be present. Minor amounts of fire damage or mechanical damage may be present. Still healthy, but with moderately diminished vigor and vitality. No significant decline noted. C. Average – Average, moderately good trees whose growth habit and physiological or fire- induced symptoms indicate an equal chance to either decline or continue with good health into the near future. Most of these trees exhibit moderate to significant small deadwood in outer crown areas, decreased shoot growth and diminished leaf color and mass. Some stem and branch dieback is usually present and epicormic growth may be moderate to extensive. Cavities, pockets of decay, relatively significant fire damage, bark exfoliation, or cracks may be present. Moderate to significant amounts of insect or disease symptoms may be present; the tree may be shaded or crowded in such a way that it is expected to negatively impact the lifespan of the tree. Tree may be in early decline. D. Below Average/Poor - trees whose growth habit and physiological or fire-induced symptoms indicate significant, irreversible decline. Most of these trees exhibit significant dieback of wood in the crown, possibly accompanied by significant epicormic sprouting. Shoot growth and leaf color and mass is either significantly diminished or nonexistent throughout the crown. Cavities, pockets of decay, significant fire damage, bark exfoliation, and/or cracks may be present. Significant amounts of insect or disease symptoms may be present; the tree may be shaded or crowded in such a way that it has negatively impacted the lifespan of the tree. Tree appears to be in irreversible decline. F. Dead or in spiral of decline – this tree exhibits very little to no signs of life.

Structure

A. Outstanding – Trees with outstanding structure for their species exhibit trunk and branch arrangement and orientation that result in a sturdy form or architecture that resists failure under normal circumstances. The spacing, orientation, and size of the branches relative to the trunk are quintessential for the species and free from defects. No outward sign of decay

S E P T E M B E R 1 9 , 2 0 1 9 / MERIDIAN CONSULTANTS LLC. PAGE 12 ATHLETIC FIELD IMPROVEMENT PROJECT, SIERRA CANYON SCHOOL – TREE REPORT

or pathological disease is present. Some trees exhibit naturally inherent branching defects, like multiple, narrow points of attachment from one point on the trunk, which would preclude them from achieving an “A” grade. B. Above average - Trees with good to very good structure for their species. They exhibit trunk and branch arrangement and orientation that result in a relatively sturdy form or architecture that resists failure under normal circumstances, but may have some mechanical damage, over-pruning, or other minor structural defects. The spacing, orientation, and size of the branches relative to the trunk are still in the normal range for the species, but they exhibit a minor degree of defects. Minor, sub-critical levels of decay or pathological disease may be present, but the degree of damage is not yet structurally significant. Trees that exhibit naturally inherent branching defects, like multiple, narrow points of attachment from one point on the trunk, would generally fall in to this category. A small percentage of the canopy may be shaded or crowded, but not in such a way that it is expected to negatively impact the structural integrity or lifespan of the tree. C. Average - Trees with moderately good structure for their species, but with obvious defects. They exhibit trunk and branch arrangement and orientation that result in a less than sturdy form or architecture, which reduces their resistance to failure under normal circumstances. Moderate levels of mechanical damage, over-pruning, or other structural defects may be present. The spacing, orientation, and size of some of the branches relative to the trunk are not in the normal range for the species. Moderate to significant levels of decay or pathological disease may be present that increase the likelihood of structural instability. Influences such as an excessive trunk lean, slope erosion, root pruning, or other growth- inhibiting factors may be present. A moderate to significant percentage of the canopy may be shaded or crowded in such a way that it is expected to negatively impact the structural integrity or lifespan of the tree. Risk of full or partial failure in the near future appears to be moderately elevated. D. Well Below Average/Poor - Trees poor structure for their species and with obvious defects. They exhibit trunk and branch arrangement and orientation that result in a significantly less than sturdy form or architecture, significantly reducing their resistance to failure under normal circumstances. Significant levels of mechanical damage, over-pruning, or other structural defects may be present. The spacing, orientation, and size of many of the branches relative to the trunk are not in the normal range for the species. Significant levels of decay or pathological disease may be present that increase the likelihood of structural instability. Influences such as an excessive trunk lean, slope erosion, root pruning, or other growth-inhibiting factors may be present. A significant percentage of the canopy may be shaded or crowded in such a way that it is expected to negatively impact the structural integrity or lifespan of the tree. Risk of full or partial failure in the near future appears to be advanced. F. Severely Compromised – trees with very poor structure and numerous or severe defects due to growing conditions, historical or recent pruning, mechanical damage, history of limb or trunk failures, advanced and irreparable decay, disease, or severe fire damage. Trees with this rating are in severe, irreparable decline, or are barely alive. Risk of full or partial failures in the near future may be severe.

Supplemental Submission - Case No. CPC-2019-627-CU-ZAD-SPR 3 messages

Philip J. Hess Wed, Mar 4, 2020 at 12:07 PM To: [email protected]

I am the attorney for Jeannie Plumb, a resident of Chatsworth who appeared and testified at the February 28, 2020 hearing on the above-referenced case. On behalf of Ms. Plumb I submit the following supplemental comments for your consideration.

Ms. Plumb advised me that at the conclusion of the public hearing the representative of the school expressly confirmed that the application before you was for a modification to the current land use permits granted to the Sierra Canyon School athletic field. This statement cannot be reconciled with the submissions from the applicant that are in the case file or with the Notice of Public Hearing for this matter.

The application in the case file includes a page discussing the Project Overview and the opening portion of a section entitled "Requests" and labeled section "c." The first item under this Requests section, numbered "i, " reads as follows:

i. Pursuant to LAMC Section 12.24-U.24, a Conditional Use Permit for the modification of conditions of approval under CPC-2005-6116-VCU-SPR and CPC-2008-3537-CU to allow the 1,620 bleacher seats for a school's athletic field.

Please note the strikeout portion of the above passage conforms to the original document, and the italicized portion is a handwritten insertion. A copy of this page of the application is attached for your review.

This statement is unintelligible. LAMC Section 12.2.4 U.24 authorizes special permits for "schools" of various types. It says nothing about, and does not authorize, modifications to previously granted Conditional Use Permits. An application to modify an existing permit must be sought as a Plan Amendment under LAMC Section 12.24 M. As previously noted by Ms. Plumb in her February 28, 2020 testimony, even if treated as an application for a new land use approval, what is being sought by Sierra Canyon cannot come within the scope of LAMC Section 12.2.4 U.24. The term "school" is defined by LAMC Section 12.03 and is unrelated to stadiums or stadium seating. The seating expansion sought by the school cannot be considered "an institution of learning which offers instruction in several branches of learning and study required to be taught in the public schools by the Education Code of the State of Californa" which is the definition of a "school" for purposes of Section 12.24 U.24.

The statement by the representative of Sierra Canyon at the conclusion of the February 28, 2020 public hearing also casts doubt on the validity of the public review process conducted on this matter to date. The Notice of Public Hearing describes the Requested Actions as including, under Item 2, "(p)ursuant to Los Angeles Municipal Code Section 12.24.U.24, a Conditional Use https://mail.google.com/mail/u/0?ik=d3f96ce06b&view=pt&search=all&permthid=thread-f%3A1660265359969260135&simpl=msg-f%3A16602653599… 1/3 3/9/2020 City of Los Angeles Mail - Supplemental Submission - Case No. CPC-2019-627-CU-ZAD-SPR Permit. . . ." That puts the public on notice that what is being sought is a new Conditional Use Permit, not a Plan Amendment under 12.24 M. If the applicant wishes to correct its filing to seek approval for a Plan Amendment under the correct code section Ms. Plumb respectfully requests that a new application be filed designating the proper code section, and a new public hearing be held on that application.

Thank you for consideration of these comments.
