REQUEST
The applicant, Harvard 826 Property, LLC, requests a Minor Use Permit (MUP), Development Review (DR), and Architectural Design Review (ADR) to construct the Promenade Flats MixedUse Project on a 1.53-acre site at 26111-26135 Bouquet Canyon Road (APNs 2811-003-016, - 017, and -018), within the Mixed-Use Corridor (MXC) zone.

BACKGROUND
One Stop Review
On June 6, 2019, the applicant submitted a preliminary One Stop Review to the Planning Division for a new four-story mixed use building to be located in the parking lot of the existing commercial shopping center (Santa Clarita Plaza) located at 26111-26135 Bouquet Canyon Road

Page 2 ends

(APNs 2811-003-016, -017, and -018) (project site). The One Stop was completed August 1, 2019.

Formal Project Submittal
On April 3, 2021, the applicant submitted a formal application for an MUP, an ADR, and a DR for the proposed project. The formal submittal included revisions to address One Stop comments, including setting the building back from residential uses, reconfiguring on-site circulation, and proposing architecture consistent with the existing center. The project underwent multiple reviews by the City’s Development Review Committee (DRC) and the applicant has worked to address comments provided throughout the DRC process. The current Project Description is summarized below under Project Description.

Project Setting
The project site is an existing commercial shopping center known as Santa Clarita Plaza. The shopping center totals 4.84 acres, and is located at 26111 to 26135 Bouquet Canyon Road (APNs 2811-003-016, -017, and -018). Santa Clarita Plaza includes several single-story commercial buildings located around courtyard areas, as well as a standalone restaurant building, occupied by IHOP. Parking is provided via 253 stalls located on all sides of the existing commercial center, including a large parking lot in the northwest corner of the site (behind the existing IHOP). APN 2811-003-016 is an undeveloped, vacant lot located directly west of the existing commercial center.

PROJECT DESCRIPTION
The proposed project would be located on a 1.53-acre portion of the site. The four-story mixeduse building would be located in the existing parking lot behind the IHOP restaurant. No existing commercial structures would be demolished or removed by the project. The first floor would include new commercial space, divided into several tenant spaces and totaling 7,234 square feet, as well as utility space and access to the upper residential floors. The upper floors include 26 one-bedroom apartments along with four live-work units and common space for residents. The live-work units would provide a total of 1,640 square feet of additional commercial space. A rooftop outdoor space would also be provided for residents. Covered resident parking would be constructed on the north and west sides of the new building. These carports would be screened from public view.

The project would also include construction of a new parking lot on vacant land in the southwest corner of the commercial center. This parking lot would construct 40 new parking stalls for use by commercial tenants and customers in the center. The parking lot also provides paved access to an existing gate for the Las Flores apartment complex, located immediately to the west, behind the existing shopping center. This complex also has existing access via the north drive aisle of the project site. Parking would be provided on site for the new project. A summary of parking for existing uses and the proposed project is provided in Table 1 below.

 A concern that the existing property and landscaping are not being adequately maintained.

ZONING AND LAND USES
The subject property has a General Plan designation and zoning designation of Mixed Use Corridor (MXC). The MXC zone is “intended for mixed use development, which is encouraged along specified commercial corridors in which revitalization of underutilized parcels or aging buildings is desired, subject to the applicable requirements of the code” (UDC Section

17.35.010). This designation contemplates both residential and commercial development, and establishes both minimum and maximum residential densities and commercial floor-area ratios (FARs) for development proposals.

The project site is surrounded by developed properties with a mixture of multifamily and commercial uses. Table 2 below summarizes the land use and zoning designations and current land uses for nearby properties.

ANALYSIS
General Plan Consistency
As described above, the project site’s land use designation of MXC is intended to encourage revitalization of underutilized parcels. The proposed project would introduce mixed-use development into an existing commercial site consisting of single-story development and surface parking.

The proposed project would be consistent with the goals, objectives, and policies of the General Plan, including, without limitation:

Objective LU 2.1: Provide adequate, suitable sites for housing, employment, business, shopping, public facilities, public utility facilities, and community services to meet current needs and the anticipated needs of future growth.

Objective LU 2.3: Increase mixed-use development where appropriate to create more livable neighborhoods, walkable business districts, and to reduce vehicle trips, while ensuring land use compatibility, through mixed-use zoning.

Page 5 ends

Policy LU 3.1.2: Provide a mix of housing types within neighborhoods that accommodate households with varied income levels.

Policy LU 3.1.3: Promote opportunities for live-work units to accommodate residents with home-based businesses.

The development proposal is consistent with the intent and goals of the MXC land use designation. The project would provide opportunities for both housing and new commercial uses in an area intended for mixed-use development, and would provide both one-bedroom apartments along with live-work housing types. The proposed development increases the mix of uses on site and in the immediate surroundings.

Unified Development Code Consistency
The project meets the definition of a housing development project in accordance with the Housing Crisis Act of 2019 (Government Code section 66300; added by Senate Bill 330). As such, the objective standards of the UDC for the MXC zone, as well as the City’s Community Character and Design Guidelines (CCDG), were applied to this project. The project complies with these objective standards.

Allowable Density and Floor Area Ratio (FAR)
The MXC zone establishes both minimum and maximum allowable residential densities and commercial square footages. The zone allows for a minimum of 11 units per acre, and a maximum of 30 units per acre. This translates to a minimum of 16 dwelling units, and a maximum of 45 dwelling units, on the 1.53-acre project site. The proposed 30-unit development is consistent with these required residential densities.

The minimum allowable commercial FAR in the MXC zone is 0.25 and the maximum FAR is

1.0. This translates to a minimum of 16,662 square feet of commercial space. The proposed project would provide 8,874 square feet of new commercial space, in addition to the 5,448 square feet provided by the existing IHOP restaurant building. The resulting 14,322 square feet of commercial space does not meet the minimum for the MXC zone, and thus an MUP is required. The provision of less commercial square footage lessens the parking demand of the overall project. Therefore, with the granting of an MUP, the proposed commercial square footage is consistent with the MXC zone’s standards.

Parking Standards
The development proposal would provide 249 parking spaces to accommodate the existing and proposed uses on site. As demonstrated in the attached parking analysis, the mixture of existing and proposed uses on site would require 249 parking stalls. As a result, the provided parking satisfies the UDC’s requirements. The project includes 34 covered parking stalls for the residential units, and, with the granting of a Minor Use Permit, the proposed carports would be consistent with the UDC requirements for residential parking. The project also includes 16 parking stalls for residential guests and 199 parking stalls to support the commercial uses on site.

Page 6 ends

Parking is provided at a ratio of 1 space per 200 square feet for the new commercial space.

In addition to meeting the UDC requirements for parking, the applicant has prepared a parking demand study (attached) evaluating the proposed mixture of uses on site. The parking demand study utilized industry-standard calculations and determined that, at the peak (e.g. busiest) hours on both weekdays and weekends, surplus parking would be available based on anticipated demand. During the weekday peak hour a surplus of 19 stalls would be available, and during the weekend peak hour, a surplus of 16 stalls would be available. The applicant has also proposed a parking management plan (attached) in order to regulate and enforce parking on site. The proposed plan would include assigning residential spaces and prohibiting residents from parking in commercial parking spaces. The conditions of approval include a condition requiring the applicant to implement a parking management plan to address the parking concerns raised during the public noticing process.

Architecture and Site Planning
The proposed building is consistent with the 50-foot height limit permitted in the MXC zone, and is sufficiently set back from the right-of-way and adjacent properties. The development proposal also includes sufficient landscaping, as required by the UDC. New lighting would be provided on site, and would be shielded and directed to minimize light spillover and glare on the public rightof-way and adjacent properties. New drive aisles are a minimum of 26 feet wide.

Concerns were raised in the requests for a hearing regarding the ingress and egress from the project site. The project utilizes the two existing and permitted driveways for the existing center.

The applicant would be required to dedicate easements and to improve these driveways to meet current Americans with Disabilities Act (ADA) standards (refer to conditions EN11 and EN 12 in the draft conditions of approval, attached in Exhibit B). The City’s Traffic Engineering Division has reviewed the existing driveways and the project is conditioned to refurbish the existing no stopping zone adjacent to the northern driveway, and to extend the existing no stopping zone adjacent to the southern driveway, to ensure that sufficient sight lines are provided for ingress and egress. In addition, 40 parking stalls would be constructed in the vacant southwest corner of the site. The project would provide access through this new parking lot to a second gated entrance to Las Flores apartments (to the west of the project site), improving access to the southern drive aisle for those residents.

Staff worked with the applicant throughout the DRC process to ensure that the proposed architecture is consistent with the requirements of the CCDG. In response, the applicant prepared several iterations of proposed architecture throughout the development review process, resulting in the final proposed architecture. The proposed building design incorporates key design elements required for the Valencia community, including the use of earth tones for paint and materials, incorporation of towers and other elements to provide vertical and horizontal articulation, and integration of curved balconies. The architecture also incorporates a substantial amount of brick to provide additional texture and to tie the new building into the existing shopping center’s architecture. As a result, the proposed architecture is complementary to the existing architecture on site and is consistent with the CCDG.

Compliance with Other Governmental Agencies
In addition to obtaining the necessary local land use entitlements, the applicant is required to comply with all applicable requirements of other government agencies that include the Los Angeles County Fire Department.

ENVIRONMENTAL STATUS
The project is exempt from the California Environmental Quality Act as a Class 32 In-Fill Development Projects exemption, pursuant to CEQA Guidelines Section 15332. A Class 32 exemption consists of projects characterized as in-fill development. The Notice of Exemption and supporting documentation is attached for reference.

PUBLIC NOTICING
On February 26, 2024, as required by UDC Sections 17.24.120 (D) and 17.06.100, public notices regarding the proposed project were mailed to all tenants of the project site along with adjacent property owners. Public notices regarding the administrative hearing were subsequently mailed on April 4, 2024 to all original recipients of public notices, along with all commenters.

Three requests for an administrative hearing, along with two other comment letters, were received during the public noticing. After the close of the noticing period, six support letters were received from tenants in the Santa Clarita Plaza shopping center. All requests and comments are attached for reference.

CONCLUSION
The proposed project is consistent with the City’s General Plan and UDC, would not endanger the public, and is physically suited for the subject site. Therefore, staff has drafted the necessary findings for approval as detailed in the “Findings” document (Exhibit A), attached to this staff report.

FINDINGS
MASTER CASE 21-086
MINOR USE PERMIT 21-012, ARCHITECTURAL DESIGN REVIEW 21-015, AND DEVELOPMENT REVIEW 21-011
On April 17, 2024, the Administrative Hearing Officer held a duly noticed hearing regarding Master Case 21-086, Minor Use Permit 21-012, Architectural Design Review 21-015, and Development Review 21-011. Based upon the written staff report, the testimony, and the evidence presented at this hearing, the Administrative Hearing Officer determines as follows:

GENERAL FINDINGS FOR MASTER CASE 21-086

1. That the proposal is consistent with the General Plan.

The project site is designated as Mixed Use Corridor (MXC) under the Santa Clarita General Plan, which states that mixed-use development “will be encouraged along specified commercial corridors in which revitalization of underutilized parcels or aging buildings is desired, as shown on the Land Use Map, subject to the applicable requirements of the zoning ordinance.” The proposed project would introduce mixed-use development into an existing commercial site consisting of single-story development and surface parking.

The proposed project would be consistent with the goals, objectives, and policies of the General Plan, including without limitation:

Policy LU 3.1.2: Provide a mix of housing types within neighborhoods that accommodate households with varied income levels.

Policy LU 3.1.3: Promote opportunities for live-work units to accommodate residents with home-based businesses.

Findings for Master Case 21-086
Minor Use Permit 21-012, Architectural Design Review 21-015, and Development Review 21-011

Page 2 of 3 ends

2. The proposal is allowed within the applicable underlying zone and complies with all other applicable provisions of the UDC.

A Multifamily Dwelling residential land use is permitted by right in the MXC zone. In addition, commercial and mixed-use development is permitted in the MXC zone, subject to the development standards in UDC Chapters 17.51 and 17.55. Any future tenants in the new commercial spaces constructed by the project will be subject to the requirements of UDC Section 17.35.010(B), the permitted use chart for the MXC zone. The proposed project complies with the development standards for the MXC zone and is located on an existing parking lot and a vacant lot within an existing shopping center.

The UDC requires the project to provide 249 parking spaces, and 249 parking spaces are provided. The building meets the MXC zone’s height requirement of 50 feet, and would comply with the drive aisle, parking lot, and landscaping requirements for mixed-use development. The project provides an appropriate residential density for the MXC zone, and although the project provides less commercial square footage than required by the MXC zone, with the approval of an MUP, the project would be consistent with the underlying zoning requirements.

3. The proposal will not endanger, jeopardize, or otherwise constitute a hazard to the public convenience, health, interest, safety, or general welfare, or be materially detrimental or injurious to the improvements, persons, property, or uses in the vicinity and zone in which the property is located.

The proposed project is not located on a hazardous site and would not include any hazardous materials. Standard construction materials and methods would be utilized to ensure safety during construction. The applicant will be required to comply with all applicable laws, ordinances, and regulations, including, without limitation: the California Building Standards Code and Fire Code. Sufficient access for firefighting purposes has been provided and verified by the Los Angeles County Fire Department (LACFD), and the applicant is conditioned to comply with all LACFD requirements. As described above, the proposed project complies with the zoning regulations for the MXC zone, including FAR, building height, residential density, and parking.

4. The proposal is physically suitable for the site. The factors related to the proposal’s physical suitability for the site shall include, but are not limited to, the following:
a) The design, location, shape, size, and operating characteristics are suitable for the proposed use;
The subject property includes existing commercial development and surface parking, along with a vacant lot. The proposed building and parking areas comply with the City’s standards for mixed-use development, including compliance with setbacks, building height, drive aisle width, and landscaping. The parking analysis for the project demonstrates that sufficient parking is provided for both the existing and proposed uses on site as required by the UDC. In addition, a parking demand analysis Findings for Master Case 21-086
Minor Use Permit 21-012, Architectural Design Review 21-015, and Development Review 21-011

for the project determined that at the peak hours on both weekdays and weekends, sufficient parking will be available on site.

b) The highways or streets that provide access to the site are of sufficient width and are improved as necessary to carry the kind and quantity of traffic such proposal would generate;
The project is accessed via the existing Bouquet Canyon Road, and no improvements to the roadway are required. The applicant is conditioned to comply with all Cityimposed engineering requirements when constructing any improvements in the rightof-way, such as sewer laterals, parkway tree installation, and ADA paths of travel at the driveways. The project will not have a significant effect on vehicle miles traveled (VMT) or traffic, and existing driveway ingress and egress from the site will be maintained.
c) Public protection services (e.g., Fire protection, Sheriff protection, etc.) are readily available; and
The Project will have public protection services provided by both the Los Angeles County Sheriff’s Department (LASD) and LACFD, and will not require any additional resources or services from those organizations as a result of its operation.

The proposal would also be required to comply with all applicable requirements of the LACFD and LASD.
d) The provision of utilities (e.g., potable water, schools, solid waste collection and disposal, storm drainage, wastewater collection, treatment, and disposal, etc.) is adequate to serve the site.

The proposed use would be located within an existing commercial center, which is located within a developed area with available and adequate utilities to serve the site.

The proposed project would connect to this existing infrastructure on site. As analyzed in the Class 32 California Environmental Quality Act exemption, water and sewer capacity is available to serve the proposed project.

Element of the General Plan as a means of mitigating the traffic impact of this project. This project is located in the Valencia B&T District. The current rate for this District is $28,710. The B&T rate is subject to change and is based on the rate at the time of payment.

Standard B&T Fee Calculation:

B&T District fees for non-residential uses on an under-utilized parcel that does not include a land division will be calculated as follows:

Retail Commercial = 14,321 sf x $28,710 x 5 = $ 125,850 16,335
Apartment = the number of units (30) x the district rate ($28,710) x 0.7 = $602,910
Total = $125,850 + $602,910 = $728,760
Note: Live/Work units may result in reduced B&T Fee.

NOTICE OF APPLICATION AND NOTICE OF ACTION FOR A MINOR USE PERMIT DATE: February 26, 2024
APPLICATION: Master Case 21-086: Minor Use Permit 21-012, Architectural Design Review 21-015, and Development Review 21-011
PROJECT LOCATION: 26111-26135 Bouquet Canyon Road
(Assessor’s Parcel Numbers 2811-003-016, -017, and -018) PROJECT APPLICANT: Harvard 826 Property, LLC
PROJECT DESCRIPTION: The applicant, Harvard 826 Property, LLC, is requesting a Minor Use Permit (MUP) to construct the Promenade Flats Mixed-Use Project on a 1.2-acre site at 26111-26135 Bouquet Canyon Road. The project would construct a new four-story mixed-use building in the parking lot behind the existing IHOP restaurant and would also construct a new parking lot on vacant land in the southwest corner of the commercial center. The new building would include 7,234 square feet of commercial space on the first floor with 30 one-bedroom apartments on the upper floors, along with rooftop amenity space for residents. Four of the apartments would be live-work units, providing an additional 1,640 square feet of commercial space. The project site is within the Mixed-Use Corridor (MX-C) zone.

No existing commercial businesses would be demolished by the project. Sufficient parking is provided on site to meet the requirements of the City of Santa Clarita’s (City) Unified Development Code (UDC). In addition, the applicant has prepared a parking study confirming that sufficient parking is provided during peak hours and has provided a parking management plan to enforce parking requirements. The proposed height of 50 feet is permitted in the MX-C zone. The applicant is requesting an MUP to provide less commercial square footage on site than the MX-C zone requires, as well as to incorporate live-work units and carports for residential covered parking into the project.

ENVIRONMENTAL REVIEW: The project is exempt from the California Environmental Quality Act as a Class 32 In-Fill Development Projects exemption, pursuant to Article 19 Categorical Exemptions, Section 15332. A Class 32 exemption consists of projects characterized as in-fill development.

In order to give the use regulations the flexibility necessary to achieve the objectives of the City’s UDC, certain uses are permitted, subject to the granting of an MUP. Because of their unusual characteristics, these specific uses require special consideration so that they may be located properly with respect to the objectives of the UDC, and with respect to their effects on surrounding properties. In order to achieve these goals, the Director of Community Development is empowered to grant approval with conditions, defer the decision to the Hearing Officer, or deny applications for an MUP.

Should you have any concerns or comments regarding this request, or wish to request the application be heard before the Hearing Officer, please forward your correspondence to the Planning Division, in writing, prior to 5:30 p.m. on March 12, 2024. If a written request for an administrative hearing is received, then the Director of Community Development may refer the project to an administrative hearing before the Hearing Officer.

If a written request for an administrative hearing is not received, the Director of Community Development will take action on this project on or after March 13, 2024. Following the date of action, there will be a 15-day period in which any interested party may appeal the action to the Planning Commission. Appeals must be made in writing and submitted, with the appropriate fee, to the Department of Community Development. If you wish to challenge the action taken on this matter in court, you may be limited to raising only those issues you or someone else raised by written correspondence delivered to the City of Santa Clarita prior to the date of action.

For further information regarding this proposal, please contact the project planner at the City of Santa Clarita Permit Center, 23920 Valencia Blvd., Suite 140, Santa Clarita, CA 91355. Telephone: (661) 255- 4330. Website: www.santaclarita.gov/planning. Send written correspondence to: 23920 Valencia Blvd., Suite 302, Santa Clarita, CA 91355.

Subject: Santa Clarita Plaza - Questions for Planning - Master Case 21-086 Importance: High
CITY WARNING: This email was sent from an external server. Use caution clicking links or opening attachments.

Patrick and Andy,
With regard to Promenade Flats Mixed Use Project at 26111‐26135 Bouquet Canyon Road, we have the following concerns with regard to the project:
1) How many new parking stalls are being added for the new building with 30 apartments, 7,000/SF of retail and the extra live work space of 3,000/SF. Last I saw was 41 parking stalls. That seems very under‐parked given the size of the building, but I am not sure I have the updated information on the development. Is the project surfaced parked, or is there subterranean parking?
2) Where will people park to go to IHOP (26811 Bouquet Canyon)? 3) Las Flores Apartments have residents and visitors that do not park behind the gate because there is not enough parking, so where will that parking spill into?
4) Has a parking study been completed for Santa Clarita Plaza to ensure that the center is parked at 4‐5/1,000, just for the existing and built out space?
5) How many additional spots will be picked up by paving the back dirt lot? In the southwest corner of the property.

We would like the project to be heard by a larger group, so many of these concerns can be addressed.

As it sits today, we have people that park in our lot and walk over to visit IHOP because of the lack of parking, so this will most certainly exacerbate the issue and is cost prohibitive to have a guard on our site daily for 8‐10 hours per day, just to monitor who comes in and out of our lot.

The ownership group of 23300 Cinema Drive has a number of concerns that they would like addressed, all relating to the above.

Thank you!

Hello Andy,
Thank you very much for calling me and listening to our concerns, as well as addressing them with the applicant. I know our concerns are shared with many other tenants in the complex. We want to stress that we are very confident that there will not be enough parking for all the businesses, residents, and guests of residents that would be using this center.

I also wanted to share another issue that may be of concern with the new project. Stonefire Grill is located in the adjacent complex and they smoke meats throughout the morning and day. The smoke typically blows into our area and is pretty significant at times. If there would be apartments with windows on the north side of the building close to Stonefire, the smoke would most certainly be an issue for the tenants. That may be something to look into.

Thank you again for following up with me, and please don’t hesitate to reach out to me with further questions.

Thank You,
Jennifer Larson

Good Morning Andy,
My name is Jennifer Larson and I am the office manager for Santa Clarita Valley Teachers Association / UniServ. We have an office in Building H in the retail complex on the property owned by Harvard 826 Property, LLC. We have some concerns about the proposed construction of a multi‐use project in the existing parking lot of the retail center. Here are some of our concerns:

1. We are a regional office for the California Teachers Association and our local teachers union chapters use our office to hold their monthly meetings. The meetings can be typically up to 30 people at a time in our conference rooms. I am including a picture of the parking lot where the building is proposed to be built. It is a busy morning here at the retail center and it is easy to see that the parking lot is quite full. We rely on the available parking to hold our meetings, so we are concerned about valuable parking being taken away adjacent to our office.

1. <image009.jpg>

2. We are also concerned about Harvard 826 Property LLC building another structure here because their existing buildings, including the one we are currently in (Building H) are in disrepair. If you were to walk around the complex, you will see that all the wood trims and arbors are dry‐rotted, chipping, and pealing. I have brought it to managements attention but nothing has been done.

1. <image010.jpg>

2. <image011.jpg>

3. <image012.jpg>

4. <image013.jpg>

3. Also, the lack of proper landscaping maintenance has been a continuous problem. You can ask many of the tenants, especially IHOP about how poorly maintained the landscaping has been in the past. I regularly have to ask that overgrowth be addressed from around our offices. I am including some pictures that I sent to management back in June and August of last year, 2023.

They have since brought in gardeners to pull out a lot of the overgrowth, but they have shown a real lack of care in the whole process, especially with the large redwood and pine trees which were butchered in the process.

1. <image014.jpg>

2. <image015.jpg>

3. <image016.jpg>

Finally, I want to mention that our rent is very high here at our offices, and for the amount of rent we pay there is very little done to maintain the complex other than the roof leaks. We are responsible for maintaining the air conditioning and heating and any electrical or plumbing issues. How will Harvard 826 Property LLC maintain and manage another building with multiple renters on this property?

I invite you to come and walk this retail complex and surrounding area yourself and really take the time to question whether adding more structures on this property is in the best interest of our city and the existing tenants of this property.

Thank you for your time, and feel free to reach out to me with any questions. 3 Best Regards,

Regarding…
Master Case 21‐086: Minor use Permit 21‐012, Architectural Design Review 21‐015, and Development Review 21‐011 Project Location: 26111‐26135 Bouquet Canyon Rd
Project Applicant: Harvard 826 Property, LLC

Dear Andy Olson and Associates,
I am writing in response to the letter from the City of Santa Clarita regarding the proposed action for a minor use permit. As the owner of Jill’s Cake Creations, which has been a proud resident of the Santa Fe Plaza for over 24 years, I would like to express my concerns about the current parking situation.

The proposed application for improvements to the property has raised several issues. Specifically, I am troubled by the lack of adequate parking. As a cake shop owner, our business frequently involves transporting large cakes to our customers’ vehicles. Unfortunately, we have been informed that we will be required to use the new parking lot at the rear of the building. This arrangement poses challenges for both our customers and their precious cake orders.

Initially, when this matter was discussed with the tenants of the plaza, it was presented as a two-story building with rooftop access. However, the most recent paperwork indicates a four-story building with rooftop access, including 30 one-bedroom apartments and 4 commercial spaces. If even half of the new apartments have two occupants, along with one resident per unit in the rest, and businesses requiring four spaces each, this would necessitate an additional 52 parking spots.

Currently, the existing parking lot is often at full capacity, especially on Saturdays—our busiest day of the week. As a result, we find ourselves carrying large cakes to the street or the far back of the complex. Furthermore, the parking area is shared with neighboring businesses and apartments. Despite management’s attempts to restrict access during evenings, cars have consistently returned after monitoring ceases. Regrettably, this situation has led to our business vehicle and my personal vehicle being towed away while we were working at the shop after hours. 3 In addition to parking concerns, we also face challenges related to access in and out of the center itself. The two existing entrances have become hazardous, with accidents occurring regularly. While I have suggested eliminating street parking to alleviate some of these issues, I recognize that this would create further parking challenges.

I kindly request that the City of Santa Clarita carefully consider the impact of these proposed changes on businesses like ours. Adequate parking and safe access are crucial for the success of local businesses and the well-being of our community.

Thank you for your attention to this matter. I look forward to hearing from you soon.

Sincerely,
Jill P Cox
Owner of Jill’s Cake Creations

NOTICE OF ADMINISTRATIVE HEARING FOR A MINOR USE PERMIT DATE: April 4, 2024
APPLICATION: Master Case 21-086: Minor Use Permit 21-012, Architectural Design Review 21-015, and Development Review 21-011
PROJECT LOCATION: 26111-26135 Bouquet Canyon Road
(Assessor’s Parcel Numbers 2811-003-016, -017, and -018)

PROJECT APPLICANT: Harvard 826 Property, LLC
PROJECT DESCRIPTION: The applicant, Harvard 826 Property, LLC, is requesting a Minor Use Permit (MUP) to construct the Promenade Flats Mixed-Use Project on a 1.2-acre site at 26111-26135 Bouquet Canyon Road. The project would construct a new four-story mixed-use building in the parking lot behind the existing IHOP restaurant and would also construct a new parking lot on vacant land in the southwest corner of the commercial center. The new building would include 7,234 square feet of commercial space on the first floor with 30 one-bedroom apartments on the upper floors, along with rooftop amenity space for residents. Four of the apartments would be live-work units, providing an additional 1,640 square feet of commercial space. The project site is within the Mixed Use Corridor (MXC) zone.

No existing commercial businesses would be demolished by the project. Parking is provided on site to meet the requirements of the City of Santa Clarita’s (City) Unified Development Code (UDC). In addition, the applicant has prepared a parking study confirming that sufficient parking is provided during peak hours and has provided a parking management plan to enforce parking requirements. The proposed height of 50 feet is permitted in the MXC zone. The applicant is requesting an MUP to provide less commercial square footage on site than the MXC zone requires, as well as to incorporate live-work units and carports for residential covered parking into the project.

Because written requests for an administrative hearing were submitted during the original noticing period for the application, an administrative hearing before the Hearing Officer has been scheduled. The written requests cite concerns about parking, safety, and traffic.

The City of Santa Clarita Hearing Officer will conduct an administrative hearing on this matter on the following date:

HEARING DATE: April 17, 2024
TIME: At or after 2:00 p.m.

LOCATION: The Centre, Oak Room
20880 Centre Pointe Parkway
Santa Clarita, CA 91350
If you wish to challenge the action taken on this matter in court, you may be limited to raising only those issues you or someone else raised at the administrative hearing described in this notice, or written correspondence delivered to the City of Santa Clarita at, or prior to, the public hearings.

RE: Promenade Flats Mixed-Use Project 26111-26135 Bouquet Canyon Road To Whom It May Concern:

I am one of the tenants of Santa Clarita Plaza, who is set to move in by April 1, 2024. I decided to hold office and establish my place of business in this location because of the Center’s excellent condition.

The owners have notified that they plan to build a new mixed-use apartment building on the parking lot next to IHOP and connect the abandoned land on our side of the building to approximately 40 parking spaces.

I think doing that will provide more than enough parking spaces for our clients and our employees. Adding the new building will help increase our business and get more clients.

I fully support this new project.

Subject: Promenade Flats Project – Shared Parking Analysis Dear Mr. Olson:

LSA is pleased to submit this shared parking analysis for the proposed Promenade Flats project (project) at 26135 Bouquet Canyon Road in Santa Clarita. The proposed project includes the development of 26 multifamily (one‐bedroom) residential units, 4 live‐work units, 7,266 square feet (sf) of first‐floor retail space and 1,640 sf of commercial live‐work space in a four‐story building within the existing Santa Clarita Plaza. The existing commercial uses would remain. In addition, the proposed project and the existing uses would share 250 total parking spaces on site.

The purpose of this shared parking analysis is to identify the forecast parking demand of the proposed project and the existing commercial uses and determine whether adequate parking would be provided on site for all uses.

PROPOSED PROJECT
The proposed project would construct 30 total multifamily residential units (26 one‐bedroom and 4 live‐work units) and 8,906 sf of commercial uses (7,266 sf of first‐floor retail space and 1,640 sf of commercial live‐work space) within the Santa Clarita Plaza.

The existing Santa Clarita Plaza includes 38,518 sf of commercial uses (8,498 sf of medical, 14,255 sf of office, 1,806 sf of salon, 5,438 sf of retail, and 8,521 sf of restaurant uses) that would remain with the project. A total of 250 parking spaces would be shared between the proposed project and the existing uses on site.

The City of Santa Clarita (City) Municipal Code states that parking shall be provided at the rate of one space per one‐bedroom residential unit, two spaces per live‐work unit, one‐half space per unit, and one space per 200 sf of commercial use. These parking rates have been applied to the proposed project uses.

It should be noted that the parking rates and parking supply for the existing uses (e.g., specific units) were previously approved by the City and/or the County of Los Angeles.

Table A (all tables attached) summarizes the parking requirements of the proposed project, the existing uses, and the entire site.
10/6/23 «P:\HAV2001\Traffic\Shared Parking Analysis2.docx» 2 The total parking supply required by the City would be 250 spaces for the proposed project and the existing commercial uses. With a total supply of 250 parking spaces, the site would meet the City’s parking requirements.

SHARED PARKING ANALYSIS
Shared parking is the use of a parking space to serve two or more individual land uses without conflict because of variations in the parking accumulation of vehicles by hour, by day. A shared parking analysis was prepared consistent with the methodology presented in Shared Parking, 3rd Edition (Urban Land Institute 2020). This shared parking analysis identifies the hourly parking demand of each individual use type within the Santa Clarita Plaza and determines whether a parking supply of 250 spaces could adequately be shared by all uses on site.

For purposes of this shared parking analysis, the forecast parking demand for the proposed project is based on the City’s Municipal Code parking requirements for residential use (one‐bedroom and live‐work units) and commercial use (first‐floor and live‐work space). The estimated parking demand for the existing medical, office, salon, retail, and restaurant uses is based on the previous site approvals and entitlement. The hourly parking demand of the proposed project and the existing commercial uses was added to determine the total parking demand on site. The hourly parking utilization for each use is based on Urban Land Institute’s Shared Parking.

The results of this shared parking analysis are presented in Tables B and C for a weekday and weekend, respectively. Table B shows a peak parking demand of 230 spaces (1:00 p.m.) on a weekday; therefore, a parking surplus of 20 spaces would occur compared to a parking supply of 250 spaces. The weekend peak parking demand of 233 spaces (11:00 a.m.) is shown in Table C.

Based on a parking supply of 250 spaces, this would result in a parking surplus of 17 spaces.

CONCLUSIONS
Based on the shared parking analysis, a parking supply of 250 spaces would adequately accommodate the total parking demand of the proposed project and the existing commercial uses on site. A parking surplus would be provided on a weekday (20 spaces) and a weekend (17 spaces) with implementation of the proposed project.

If you have any questions, please call me at (949) 553‐0666.

Sincerely,
LSA Associates, Inc.

MEMORANDUM
DATE: January 30, 2024
TO: Andy Olson, AICP, Associate Planner, City of Santa Clarita FROM: Dean Arizabal, Principal, LSA
SUBJECT: Parking Management Plan for the Promenade Flats Project (LSA Project No. HAV2001)
LSA developed a Parking Management Plan (PMP) as required by the City of Santa Clarita (City) for the proposed Promenade Flats Project (project). The PMP was conducted to ensure that adequate and convenient parking for residents and guests of the proposed project is provided. This PMP has been prepared based on prior work experience on similar projects and LSA’s understanding of the City Municipal Code parking requirements. This PMP will set forth the framework to ensure more than adequate parking is provided for the proposed project.

Project Description
Harvard 826 Property LLC is proposing to construct 30 multifamily residential units (26 one‐bedroom apartments and 4 live‐work units) and 8,906 square feet (sf) of commercial use (7,266 sf of first‐floor retail space and 1,640 sf of commercial live‐work space) in a four‐story building at 26135 Bouquet Canyon Road in Santa Clarita. The proposed project also includes 250 parking spaces. The approximately 1.2‐acre project site is located along the west side of Bouquet Canyon Road, north of Magic Mountain Parkway and south of Cinema Drive (Assessor’s Parcel No. 2811‐003‐018) in the community of Valencia. Access to the project site will be provided via an existing full‐access driveway on Bouquet Canyon Road. The conceptual site plan (provided in Attachment A) illustrates the proposed parking layout.

Project Parking Requirement by the City
According to City Municipal Code Section 17.55.050 (Parking Requirements), the proposed project is required to provide 250 parking spaces as shown in Table A (provided in Attachment B), including 50 spaces for the proposed residential use (34 resident and 16 guest spaces), 45 spaces for the proposed commercial use, and 155 spaces for the existing commercial use. Therefore, in compliance with the City Municipal Code, the proposed project will provide 250 total parking spaces. 1/30/24 «P:\HAV2001\Traffic\PMP\PMP Memo3.docx» 2
Allocation of Provided Parking Spaces
As shown on the conceptual site plan, the proposed project will provide 250 total parking spaces, including 34 resident‐only spaces, 200 commercial‐only spaces, and 16 shared spaces for residential guests and commercial uses. Subject to approval by the Director of Community Development, residential guest parking may be used to supplement the parking for the commercial component of a mixed‐use development.

Parking Management Plan Measures
The following elements will be implemented by on‐site management in order to manage parking utilization on‐site:

1. The designations of the 250 parking spaces shall be clearly identified by the property owner or property management company (i.e., resident‐only [34], commercial‐only [200], and shared for residential guests and commercial uses [16]) by signage and/or pavement markings placed at each individual parking space. The property owner or the property management company shall maintain the parking space designations at all times.

2. The property owner or the property management company shall provide each resident with comprehensive parking plans (indicating locations and space designations) and detailed parking permit and guest pass requirements and procedures (including the number of permits and guest passes that are available and how to obtain a permit or guest pass). These materials shall be provided upon a prospective resident tour and/or at lease signing. In addition, this parking information could be presented as reminders in resident newsletters and emails.

3. Upon the residents’ request of a residential parking permit, the property owner or the property management company shall issue 1 parking permit for each of the 26 one‐bedroom apartments and 2 parking permits for each of the 4 one‐bedroom, live‐work units). A residential parking permit could be a sticker/decal on a windshield or a hang tag on the rearview mirror. In any case, these permits would be clearly visible for monitoring or inventory of residential parking.

4. As shown in Table A, there will be 26 one‐bedroom apartments and 4 one‐bedroom, live‐work units. Following the issuance of 1 parking permit for each apartment and 2 parking permits for each live‐work unit, there will be an excess of 1 parking space. An additional parking permit can be issued upon request to an apartment resident on a first‐come/first‐served basis, as long as the City Municipal Code parking requirement is maintained (34 total resident parking spaces for the 26 apartments and 4 live‐work units).

5. Guest parking passes shall be obtained from the property owner or the property management company on a first‐come/first‐served basis. Similar to residential parking permits, temporary parking passes for guest visits could be a hang tag on the rearview mirror that are issued and collected upon guest arrivals and departures.

6. Residential parking shall be implemented and regulated through a parking enforcement company.
1/30/24 «P:\HAV2001\Traffic\PMP\PMP Memo3.docx» 3

7. The property owner, property management company, or parking enforcement company shall continuously monitor and ensure that the total number of issued residential parking permits does not exceed the parking supply.

8. The property owner, property management company, or parking enforcement company shall work with adjacent retail property owners and/or retail property tenants to minimize residential parking in adjacent retail parking spaces and take appropriate remediation measures such as towing vehicles in violation at the vehicle owner’s expense.

9. All vehicles will be required to have residential parking permits or guest parking passes. Vehicles parked in residential spaces without a residential permit or guest pass will be towed at the vehicle owner’s expense.

10. The parking for the proposed project shall be monitored and evaluated on a quarterly basis by the property management and appropriate actions shall be taken to ensure that the necessary PMP measures are being implemented and enforced. This includes the towing of vehicles in violation of the designated parking spaces at the vehicle owner’s expense.

Parking Management Plan Objectives
The PMP for the proposed project emphasizes key objectives that include identifying and assigning parking spaces, clearly reserving spaces for various users, and implementing parking control measures to ensure parking availability and enforcement. These objectives are described below.

PMP Objective –The PMP shall identify the location of specific parking facilities and the number of parking spaces in such facilities that are available to meet the parking demand of the site.  Project Compliance: Per Section 17.55.050 (Parking Requirements), the proposed project is required to provide 250 parking spaces. The proposed project will provide 250 total parking spaces, as shown in Table A and illustrated on the conceptual site plan. The 250 parking spaces will be comprised of 34 resident‐only spaces, 200 commercial‐only spaces, and 16 shared spaces for residential guests and commercial uses. Therefore, the proposed project will meet the City Municipal Code parking requirement. There are no extraordinary features of the proposed project that necessitate more parking than required by the City Municipal Code. In addition, the parking spaces are intended for use by motorcycles, moped, and passenger vehicles only. Non‐ passenger vehicle parking will not be permitted on site.

PMP Objective – Parking on site shall be delineated as being reserved for the various users, and whether other control measures are used to ensure the availability and enforcement of the plan.  Project Compliance: Resident‐only, commercial only, and shared (residential guest and commercial) parking spaces are denoted on the on the conceptual site plan. These dedicated parking spaces will be designated by proper signage and/or pavement markings. Vehicles in violation of the designated parking spaces, the residential parking permits, and the guest parking passes will be towed at the vehicle owner’s expense. 1/30/24 «P:\HAV2001\Traffic\PMP\PMP Memo3.docx» 4
PMP Objective – The owner or manager designee of the site shall provide an accurate and current record of the uses and parking allocation for the site. The Director of Community Development may require this record to be provided or updated annually if it is determined that parking for the proposed use is impacting adjacent properties or street, and when the owner applies for a change in use or development plan review for the subject site.
 Project Compliance: The property owner or the property management company will monitor the project parking on a quarterly basis. The property owner will also provide an accurate and current record of the uses and parking allocation for the site. The property owner or the property management company will provide this record or update annually upon request of the Director of Community Development, or when the property owner applies for a change in use or development plan review.

To: City of Santa Clarita Planning Department
From: Envicom Corporation, CEQA Environmental Consultants Subj: Assessment of Santa Clarita Plaza Apartments Project for a Categorical Exemption as a Class 32 In-Fill Development (Envicom Project No. 2021-053-01) This document has been prepared for the City of Santa Clarita, as the CEQA lead agency, for consideration of the proposed Santa Clarita Plaza Apartments Project (the project) located at 26111 Bouquet Canyon Road in the City of Santa Clarita as eligible for a Class 32 Categorical Exemption under the California Environmental Quality Act (CEQA) as an infill project. The following documentation and justifications have been compiled pursuant to the 2023 CEQA updates.

Categorical exemptions are defined in CEQA for various types of projects which the Secretary of the Resources Agency of the State of California has determined do not have a significant effect on the environment, and therefore are not subject to further environmental review under CEQA.

The Class 32 exemption (Section 15332 of the State CEQA Guidelines) is intended to promote infill development within urbanized areas. The class consists of environmentally benign infill projects, which are consistent with local general plan and zoning requirements.

Pursuant to Section 15332 of the State CEQA Guidelines, for a project to be eligible for a Categorical Exemption as a Class 32 In-fill Development project, it must meet the following conditions or “Criteria”:

A. The project is consistent with the applicable general plan designation and all applicable general plan policies as well as with applicable zoning designation and regulations.

B. The proposed development occurs within city limits on a project site of no more than five acres substantially surrounded by urban uses.

C. The project site has no value as habitat for endangered, rare or threatened species.

D. Approval of the project would not result in any significant effects relating to traffic, noise, air quality, or water quality.

E. The site can be adequately served by all required utilities and public services.

The justification for use of a Class 32 Categorical Exemption for the proposed project as an infill development in compliance with CEQA is provided below in the following format: I. Project Description, II. Evaluation of Class 32 Exemption Criteria, III. Consideration of Exceptions, and IV. Conclusion.

I. PROJECT DESCRIPTION
Existing Conditions
The project site comprises a total of approximately 1.2 acres located on an existing parking lot for the Santa Clarita Plaza, a small, one-story shopping center with an address of 26111 Bouquet Canyon Road in the Saugus community of the City of Santa Clarita. The project site is located between Santa Clarita Plaza to the south, Cinema Park shopping center to the north, the Las Flores Apartments to the west and an IHOP restaurant to the east. The proposed building is located on the same parcel as the IHOP restaurant. Access is provided from two existing driveways to Bouquet Canyon Road. Bouquet Canyon Road is a six-lane major arterial running north-south. It connects to Valencia Boulevard, a nine-lane major arterial, approximately 0.25 miles to the north. West of the intersection Valencia Boulevard curves south behind the project site approximately 0.25 miles away. Cinema Drive, a three-lane road located 200 feet north of the project site, runs east-west and connects Bouquet Canyon Road to Valencia Boulevard. Magic Mountain Parkway, another major arterial connects to Bouquet Canyon Road approximately .25 miles south.

The south fork of the Santa Clara River is approximately 400 feet west of the project site, and the Santa Clara River itself a little over .25 miles to the north. To the east on the other side of Bouquet Canyon Road are railroad tracks and a series of hills. Apart from these physical barriers buildable land surrounding the project site is mostly developed. Industrial, light industrial, and commercial uses are located south of the site below Magic Mountain Parkway. Southwest of the site below the Parkway are large residential subdivisions. North and west of the site commercial developments appear to occupy all of the available buildable land.

Project
The proposed project consists of the construction, operation, and maintenance of a 52,418 squarefoot, four-story mixed-use building with 26 one-bedroom residential units, four one-bedroom live/work units, and seven commercial suites. Total residential floor area is 43,512 square-feet and total commercial floor area is 14,394 square-feet. Commercial floor area includes 7,266 square-feet of commercial suites, 1,640 of live/work area, and 5,488 square-feet for the existing IHOP restaurant located on the east end of the parcel. The first floor of the new building will contain the commercial suites plus a residential lobby, the second and third floors will contain eight one-bedroom units, two live/work units, and a residential amenity room, the fourth floor will contain 10 one-bedroom units plus a terrace, and there will be a deck with BBQ area on the rooftop for residents. In addition to the mixed-use building 41 new parking spaces will be built on a 0.33-acre vacant parcel south of the project site behind (west) the Santa Clarita Plaza shopping center.

The project would require the following land use entitlements from the City of Santa Clarita:
• A Development Review (DR) to review the proposed development; • An Architectural Design Review (ADR) to review the proposed architecture; and, • Minor Use Permit (MUP) for development in the MXC zone that does not meet the minimum commercial square footage and for live/work quarters.

Construction
The site of the proposed building is previously developed, and the site of the proposed parking lot has been previously graded. The asphalt parking lot will be removed, but no import or export of soil is proposed as earthwork is expected to be balanced on site with existing soils excavated and recompacted.

II. EVALUATION OF CLASS 32 EXEMPTION CRITERIA
The following subsections provide discussion and analysis of the project’s consistency with the criteria listed in Section 15332 of the State CEQA Guidelines, for a project to be eligible for a Categorical Exemption as a Class 32 In-fill Development project.

A. The project is consistent with the applicable general plan designation and all applicable general plan policies as well as with applicable zoning designation and regulations.

The project site is zoned MXC (Mixed-Use Corridor), and the land use designation is Mixed-Use Corridor (MXC)1. Both the zoning and the land use designation allow a residential density up to 30 dwelling units per acre and maximum FAR of 1.0 for a non-residential component. The proposed project has 25 units per acre and a FAR of approximately 0.27. 1 City of Santa Clarita, Mapping Your City application, Accessed June 21, 2023 at https://maps.santaclarita.com/portal/apps/webappviewer/index.html?id=4b3cfb271314475db6518999b4747876 November 16, 2023

Page 4 ends

The project meets the development standards for the zone and is contextually appropriate for the location given the existing adjacent commercial and residential uses, and therefore is consistent with the applicable policies and regulations of the General Plan and zoning designation and meets criteria A.

B. The proposed development occurs within city limits on a project site of no more than five acres substantially surrounded by urban uses.

The project site is approximately 1.2 acres and is located within an urbanized area within the City of Santa Clarita. The project site is an existing parking lot located between Santa Clarita Plaza shopping center to the south, Cinema Park shopping center to the north, the Las Flores Apartments to the west and an IHOP restaurant to the east. Physical barriers such as the Santa Clara River and its south fork to the north, south and west, and railroad tracks and hills to the east preclude development in those locations, but the area is otherwise nearly completely urbanized.

The area bordered by Valencia Boulevard to the north and west, Bouquet Canyon Road to the East, and Magic Mountain Parkway to the south, where the project site is located, is fully developed primarily with commercial uses, but also includes some multi-family residential south of the project site. East of Valencia Boulevard along Magic Mountain Parkway are a string of auto dealerships and more large commercial shopping centers. Therefore, the project meets criteria B.

C. The project site has no value as habitat for endangered, rare or threatened species.

The site of the proposed mixed-use building is a paved parking lot with some minor landscaping.

There is no potential habitat for endangered, rare or threatened species on the site. The vacant lot where the new parking will be constructed is surrounded by asphalt pavement and buildings and is covered in non-native annual grasses and ruderal species. There are no shrubs or trees or native flowering plants that may attract native species for nesting or feeding, and therefore no habitat that could potentially support some endangered, rare or threatened species, as these are species with specific habitat needs. The project therefore meets criteria C.

D. Approval of the project would not result in any significant effects relating to traffic, noise, air quality, or water quality.

Traffic Effects
The project would have a significant impact if it would conflict or be inconsistent with CEQA Guidelines section 15064.3(b)(1) relating to Vehicle Miles Traveled (VMT). A transportation memorandum by LSA2 determined, per the City’s Transportation Analysis Updates in Santa Clarita document published May 2020, that the project meets the City’s VMT screening criteria.

The Transportation Analysis Updates in Santa Clarita recommends that locally serving retail uses (less than 50,000 sf) and residential uses located in a low VMT area are screened from a VMT analysis. The project is located in a low VMT area and includes 8,906 square-feet of commercial floor space in the building (first floor commercial plus live/workspace). If the existing IHOP 2 Transportation Memorandum for the Santa Clarita Plaza Project, LSA, April 28, 2022.

restaurant located on the same parcel was included in the calculation the total would only amount to 14,394 square-feet, well below the screening criteria. Because construction traffic is temporary, there is no permanent increase in VMT and effectively no VMT related impacts. The memorandum discusses other transportation considerations but for the purposes of a Class 32 Categorical Exemption traffic impacts are limited to CEQA Guidelines section 15064.3(b)(1).

Therefore, there would be no significant effects relating to traffic.

Noise Effects
A noise study was prepared for the project by LSA Associates to evaluate potential noise impacts expected to result from the proposed project.3 Both construction and operational impacts were assessed.

Existing Conditions
Short-term and long-term noise measurements were made in order to determine existing ambient noise levels in the vicinity of the project site. Short term noise measurements were conducted on a Wednesday and Thursday, January 25 and 26, 2021 at three locations adjacent to the project site. Long term noise measurements were conducted on the same dates for 24 hours at two locations. The results are shown in Table 1, Project Site Ambient Noise Measurements.

Noise Standards
Section 11.44.040 of the City’s Municipal Code has established daytime and nighttime exterior noise limits in regions designated as residential, and commercial and manufacturing, as shown in Table 2, Santa Clarita Maximum Exterior Noise Limits.

Table 2
Santa Clarita Maximum Exterior Noise Limits

Day 7AM – 9PM 80
Night 9PM-7AM 70
Source: Santa Clarita MC Section 11.44.040
Construction
The Santa Clarita Municipal Code requires construction to take place between 7:00 AM to 7:00 PM on weekdays, 8:00 AM to 6:00 PM on Saturdays, and no construction is allowed on Sundays or national holidays (SCMC Section 11.44.080). The City does not set any limits on the level of construction noise, only allowed hours. Provided the project respects the allowed construction hours, as it must, it would comply with the standards. However, a significant increase in noise above accepted nuisance thresholds could constitute an impact. Therefore, project construction noise was estimated and compared to the 80 dBA Leq standard for noise impacts at a residential use utilized by the Federal Transit Administration (FTA). The FTA does not have jurisdiction over the project, however, it is helpful to compare the project to a standardized threshold to evaluate potential impacts.

The noise study calculates that the worst-case combined noise level during construction would be during the grading phase if/when a grader, bulldozer, and water truck are in use at the same time.

The combined noise generated during such a scenario would be 88 dBA Lmax at a distance of 50 feet from the active construction area. When the usage factor of the equipment is added to the equation (the percentage of time during construction that a piece of equipment is operating at full power, i.e., producing peak noise), the worst-case scenario drops to 84 dBA Leq at a distance of 50 feet. Noise energy dissipates over distance so any receptor further than 50 feet away would experience less noise than the projected Lmax and Leq. The nearest residences are approximately 175 feet west of the proposed new building, and 75 feet north of the proposed new parking lot.

Max noise emanating from the site of the new building would be 73 dBA Leq (77 Lmax) at the residences, and max noise emanating from the site of the new parking lot would be 78 dBA Leq (82 Lmax) at the residences. The average noise level (Leq) in both instances would be below the 80 dBA Leq FTA standard, therefore, project construction would not result in significant effects relating to noise.

Operation
The project will introduce new traffic trips to the area which will add to existing traffic noise, and introduce new stationary equipment, such as HVAC equipment, to the project site. Existing traffic noise on Bouquet Canyon Road was calculated in the Noise Study. With an estimated ADT (average daily trips) of 37,650 daily trips at 112 feet from the centerline of the road the noise level is calculated at 70 dBA CNEL. The project is anticipated to add 636 ADT to the area, resulting in an estimated 38,286 ADT. This increase would not change perceptible noise levels as a doubling of traffic is necessary to produce a 3 dBA increase in noise, which is a change perceptible to the human ear only in an enclosed environment. The addition of 636 ADT would only increase noise by 0.07 dBA and therefore would not be perceptible and not result in an impact. Noise generated by the coming-and-going of vehicles from the new development would add to noise in the existing driveways and parking lots, however, the amount of activity would not be intense enough to create a doubling of noise in the immediate area and should not create a perceptible increase in noise. Vehicles traveling at a slow speed, as through a parking lot, do not generate the same amount of noise as high speed traffic, and impacts from the general activity of the proposed project would not result in a significant noise impact.

New stationary noise sources introduced by the project would primarily be 40 new HVAC units on the rooftop. According to the noise study each commercial HVAC unit would generate a sound power level (SWL) that ranges between 76.0 dBA and 79.0 dBA, which would be equivalent to noise levels of 44.4 dBA Leq and 47.4 dBA Leq at a distance of 50 ft. Each HVAC unit associated with residential uses would generate a sound pressure level (SPL) ranging between 36.3 dBA Leq and 39.3 dBA Leq at a distance of 50 ft. The composite noise level of all 40 HVAC units would be 56.2 dBA at a distance of 50 ft. As the units are on top of the roof they are attenuated by the roofline, and the parapet surrounding the roofline, which would reduce noise by a minimum of 8 dBA. At the existing residential units the noise generated by HVAC units on the proposed building would result in 37.6 dBA Leq, and the nearest commercial structure would experience 49.1 dBA Leq. The amount of noise generated by HVAC units would therefore be below the noise measured (Leq) at each short-term monitoring location as shown in Table 1.

Therefore, noise from the HVAC units would not result in a noticeable change in the intensity of noise (3 dBA or greater), would not violate City noise limits shown in Table 2, and would not result in a significant impact.

Therefore, as demonstrated, neither project construction nor project operation would not result in significant noise impacts.

Potential vibration impacts were also assessed in the noise study but are not presented here as they are not considered in the evaluation of a Categorical Exemption. The study found no significant impacts according to thresholds not applicable to the project’s Class 32 exemption.

Air Quality Effects
An air quality study was prepared for the project by LSA Associates to evaluate potential air quality impacts expected to result from the proposed project.4 Both project construction and operations were assessed.

Air Quality
The primary regulator of air quality in the area is the South Coast Air Quality Management District (SCAQMD), the agency responsible for air pollution control within the South Coast Air Basin (SCAB), of which Los Angeles County is part of. Rules and regulations promulgated by the SCAQMD are derived from the federal Clean Air Act and state Clean Air Act which mimics the federal legislation and provides stricter controls in certain instances. The primarily regulatory and policy document the SCAQMD is tasked with implementing is the Air Quality Management Plan (AQMP) which is developed by the SCAQMD and the Southern California Association of Governments (SCAG). SCAG develops portions of the AQMP that address transportation control measures, land use, and growth projections within districts that have not met air quality standards.

The 2022 AQMP relies on the growth estimates and transportation control measures found in the SCAG 2020-2045 Regional Transportation Plan/Sustainable Communities Strategy (2020-2045 RTP/SCS). The SCAQMD has established project-level significance thresholds which are used to assess regional and localized impacts of project-related criteria pollutant emissions. Nonexceedance of these thresholds is used to determine consistency with the AQMP. According to the AQMP, the principal contributor to air quality challenges in the air basin is mobile source emissions.

The project’s maximum daily emissions of criteria air pollutants during construction were estimated using the California Emissions Estimator Model (CalEEMod) version 2011.1. Projects in the SCAQMD with daily emissions that exceed any of the following emission thresholds may be considered significant for purposes of an evaluation under CEQA.

Source: Air Quality and Greenhouse Gas Emissions Impact Analysis Memorandum, Attachment C 1 Construction emissions reflect required compliance with fugitive dust control per SCAQMD Rule 403.

As shown in the table, the project would not exceed SCAQMD significance thresholds for air quality impacts.

Localized Significance Thresholds (LSTs) were developed to evaluate ambient air quality on a local level in addition to the more regional emissions-based thresholds of significance. The LST methodology addresses specific emissions, namely oxides of nitrogen (NOx), carbon monoxide (CO), and particulate matter (PM-10 and PM-2.5). LSTs represent the maximum emissions from a project that are not expected to cause or contribute to an exceedance of the most stringent applicable federal or state ambient air quality standard, and they are developed based on the ambient concentrations of that pollutant for each source receptor area and distance to the nearest sensitive receptor. Sensitive receptors are populations with the greatest sensitivity to air pollution exposure and include elderly, young children, the acutely and chronically ill, and persons engaged in strenuous work or exercise. The closest sensitive receptors that could potentially be subject to localized air quality impacts associated with construction of the proposed project would be the residences to the west, because they may be occupied for extended periods, and residents may be outdoors when exposure is highest.

This evaluation is based on maximum daily onsite construction emissions that would occur during any phase of project construction. Daily averages would be lower than the reported maximum amounts. Table 5, Project Construction Related LST Evaluation below shows the relevant threshold and the estimated peak daily onsite emissions during the construction phases that would generate the highest level of onsite emissions for each pollutant evaluated for LST impacts.

As shown in the table, the project’s maximum daily onsite construction emissions would not exceed the relevant LST screening table thresholds for LST-related criteria pollutants, and impacts would be less than significant.

Operational air quality impacts were assessed and the results are presented in Table 6, Maximum Daily Operations Emissions (pounds/day).

Table 6
Maximum Daily Operations Emissions (pounds/day)
As shown above, project operations would not result in the violation of any SCAQMD thresholds and there would be no significant impacts.

Odors
During construction heavy‐duty equipment use would emit odors, however, construction‐ produced odors would be intermittent and cease to occur after each workday and once construction is completed. No other sources of objectionable odors would be present during construction. During operations the project would not be expected to produce objectionable odors as the use, residential units and a commercial component are not the type of use that results in the production of significant odor impacts such as oil refineries, agricultural use, or some industrial uses. Odor impacts would be less than significant.

Potential greenhouse gas impacts were also assessed in the LSA study but are not presented here as they are not considered in the evaluation of a Categorical Exemption. The study found no significant impacts according to analysis that is not applicable to the project’s Class 32 exemption.

Water Quality Effects
The proposed project would add a structure and landscaping to a site that is currently covered by impervious surfaces and would add an impervious surface to a lot that is currently undeveloped.

This will not result in significant effects to water quality either during construction or postconstruction. According to Section 10.04.070 of the Santa Clarita Municipal Code the project must produce a Stormwater Pollution Prevention Plan (SWPPP) prior to issuance of grading or building permits. The plan must demonstrate which Best Management Practices (BMPs) are to be employed to retain sediments from areas disturbed by construction; retain construction-related materials, wastes, spills, or residues; contain runoff from equipment and vehicle washing; and control any potential erosion. The project will be required to submit a SWPPP, to demonstrate code compliance to the satisfaction of the City prior to final plan approval. Compliance with these regulations would ensure no significantly impacts to water quality during construction.

A hydrology report from CRC Enterprises5 evaluated the existing conditions of the site, the proposed conditions, and the proposed stormwater system and determined the project meets the requirements of the Los Angeles County Department of Public Works LID Manual. The proposed building is not adding any new impervious surfaces to the site, as the site is currently paved. As such, runoff from the new building will be routed into the existing drainage network as the system adequately handles the required 50-year storm event threshold (0.95 inches). The new parking lot adds new impervious area to the site and as such adds an underground infiltration trench within the confines of the new lot to capture stormwater from a 0.95 inch rain event within its drainage area. The report determines the overall drainage design of the site is adequately designed to handle runoff from a 50-year storm event, and is consistent with the requirements of the County of Los Angeles, Department of Public Works. Therefore, operation of the project would not result in significant impacts to water quality.

E. The site can be adequately served by all required utilities and public services.

The project site is located within an existing shopping center surrounded by commercial buildings to the north, south, and east, and a multifamily residential complex to the west. All necessary utilities are present and serving the shopping center or existing apartment complex and will be available for the new development. Water and sewer capacity is available for the project. As stated in the SCV Water 2020 Urban Water Management Plan existing and planned water supplies are adequate to meet demand during normal, single and multiple-dry year periods through 2050 within the SCV Water service area, based upon their growth assumptions. Project sewage will be treated at the Saugus Water Reclamation Plant which has a design capacity of 6.5 million gallons of wastewater per day (MGD) and is currently processing 5.2 MGD, and therefore has capacity to serve the project.6

A small mixed-use residential building would not require an expansion of any necessary public services, such as police, fire, or garbage collection, all of which currently serve the site and area.

Therefore, the site can be adequately served by required utilities and public services.

III. CONSIDERATION OF EXCEPTIONS
Section 15300.2 of the CEQA Statutes and Guidelines provides a list of exceptions for consideration of a project as categorically exempt. As listed in the City’s Class 32 Requirements, those exceptions relevant to the Class 32 Categorical Exemption, and justification that none of the Exceptions would apply to the proposed project are discussed below:

A. Cumulative Impact – The project and successive projects of the same type in the same place would not result in cumulative impacts.

The project would be constructed within an urbanized area of the City on a previously developed site, consistent with the General Plan land use designation and zoning, and consistent with the land use assumptions that underlie the Southern California Association of Governments (SCAG) 2020-2045 Regional Transportation Plan/Sustainable Communities Strategy, the regional document certified by CARB to meet the State’s 2035 GHG reduction targets. The project therefore falls within anticipated growth rates for the City and region. In the 6th cycle Regional Housing Needs Allocation Santa Clarita has been allocated 10,031 housing units for which it must identify suitable sites to accommodate that amount of new housing. The project provides 30 housing units toward the allocation and projects of the same type in the same area would add more. As infill redevelopment the project is providing new housing and commercial space in the most efficient and environmentally benign manner possible. As such, the project and others of its type would contribute to the required housing needs of the City in an efficient manner and would not be anticipated to result in cumulative impacts.

B. Unusual Circumstances – There are no unusual circumstances that would create a reasonable possibility of significant effects.

The project site is already developed, as are the parcels surrounding it, and the existing shopping center and apartments have been in operation for decades. There is nothing unusual about the project site or setting with the exception of the south fork of the Santa Clara River west of the project site. This is unusual only in that it is not typical. All of the development in the immediate area is in proximity to the south fork or the main channel, and as far as the project is concerned, as infill redevelopment surrounded by development that is near the south fork, it is not an unusual circumstance of concern. Regardless, the presence of the south fork nearby is not an unusual circumstance that could reasonably be argued to result in the project creating a significant impact.

C. Scenic Highways – The project would not result in damage to scenic resources, including, but not limited to, trees, historic buildings, rock outcroppings, or similar resources, within an officially designated scenic highway.

The closest potential State Scenic Highway to the project site is a portion of Interstate 5 that is eligible for designation, beginning where it intersects Highway 14 and ending where it intersects November 16, 2023
Santa Clarita Plaza Apartments Project for a Categorical Exemption as a Class 32 In-Fill Development (Envicom Project No. 2021-053-01)

Page 13 ends

Highway 126. The project site is not near or visible from the interstate and would not result in damage to any scenic resources associated with it.

D. Hazardous Waste Sites – The project is not located on a site that the Department of Toxic Substances Control and the Secretary of the Environmental Protection have identified, pursuant to Government Code section 65962.5, as being affected by hazardous wastes or clean-up problems.

The Department of Toxic Substance Control (DTSC) EnviroStor database7 indicates there are no existing or past hazardous waste facilities or cleanup sites within 1,000 feet of the project site.

The State Water Resources Control Board’s GeoTracker8 database indicates that the United Oil gas station located at 26015 Bouquet Canyon Road is the site of a former LUST (leaking underground storage tank) cleanup. A leak was detected in 1986 and a vapor extraction well was installed in 1987. The site underwent soil vapor extraction from 1989 to 1991. The USTs present at the site were all removed and replaced in 1999. The case was closed in 2006 when there were no detectable traces of pollutants in nearby monitoring wells.

The project site itself is not associated with any record in the Cortese List (the resource list compiled pursuant to Government Code section 65962.5), as indicated via the EnviroStor database and the State Water Resources Control Board’s GeoTracker database. The United Oil station is not close enough to the project site to have been affected by it, and the case has been closed at the satisfaction of the DTSC. Therefore, the project is not located on a site that the Department of Toxic Substances Control and the Secretary of the Environmental Protection have identified, pursuant to Government Code section 65962.5, as being affected by hazardous wastes or clean-up problems.

E. Historical Resources – The project would not cause a substantial adverse change in the significance of an historical resource.

Neither the project site nor any properties in the immediate vicinity of the project site have been designated as historic resources or identified as a potential historic resources in the Cultural and Historical Resources section of the Conservation and Open Space element of the General Plan, or the Historic Preservation Survey & Planning Analysis from August 2009. There are no structures on the site, construction of the project would not require demolition or modification of any structures, and none of the adjacent structures are identified as potential historic resources nor would they be eligible as such as all were constructed in or after 1987, therefore, the project would not cause a substantial adverse change in the significance of an historical resource. 7 Department of Toxic Substances Control, EnviroStor, Accessed June 22, 2023 at:

MEMORANDUM
DATE: April 28, 2022
TO: Robert Neman, Harvard 826 Property LLC, Manager
FROM: Dean Arizabal, LSA, Principal
SUBJECT: Transportation Memorandum for the Santa Clarita Plaza Project (LSA Project No. HAV2001)
The purpose of this transportation memorandum is to describe and document potential transportation impacts associated with the implementation of the proposed Santa Clarita Plaza Project (project). This technical information is provided for project review under the California Environmental Quality Act (CEQA).

PROJECT DESCRIPTION
Harvard 826 Property LLC is proposing to construct 30 multifamily residential units (inclusive of four live/work units), 7,266.1 square feet (sf) of first‐floor retail space, and a 3,027.4 sf rooftop yoga studio in a four‐story building at 26135 Bouquet Canyon Road in Santa Clarita (Figures 1 and 2; all figures are in Attachment A). The approximately 1.2‐acre project site is located along the west side of Bouquet Canyon Road, north of Magic Mountain Parkway and south of Cinema Drive (Assessor’s Parcel No. 2811‐003‐018) in the community of Valencia. Access to the project site will be provided via an existing full‐access driveway on Bouquet Canyon Road.

TRANSPORTATION ANALYSIS
This section includes an analysis of the project’s impacts to the transportation system based on the significance thresholds in Appendix G of the State CEQA Guidelines and provides a thorough justification for the conclusions provided herein.

Regulatory Setting
The following is a summary of State, regional, and local regulations that apply to transportation and circulation within the project study area.

State
Senate Bill 743. On September 27, 2013, Governor Jerry Brown signed Senate Bill (SB) 743 into law and codified a process that revises the approach to determining transportation impacts and mitigation measures under CEQA. SB 743 directed the Governor’s Office of Planning and Research (OPR) to administer new CEQA guidance for jurisdictions by replacing the focus on automobile vehicle delay and level of service (LOS) or other similar measures of vehicular capacity or traffic 4/28/22 «P:\HAV2001\Traffic\Transportation Memo2.docx» 2 congestion in the transportation impact analysis with vehicle miles traveled (VMT). This change shifts the focus of the transportation impact analysis from measuring impacts to drivers, such as the amount of delay and LOS at an intersection, to measuring the impact of driving on the local, regional, and statewide circulation system and the environment. This shift in focus is expected to better align the transportation impact analysis with the statewide goals related to reducing greenhouse gas emissions, encouraging infill development, and promoting public health through active transportation. As a result of SB 743, the California Office of Administrative Law cleared the revised State CEQA Guidelines on December 28, 2018, with a statewide implementation date of July 1, 2020. The OPR Technical Advisory on Evaluating Transportation Impacts in CEQA (OPR Technical Advisory)1 provides a resource for agencies to use at their discretion.

Regional
Southern California Association of Governments. The Southern California Association of Governments (SCAG) is an association of county and city governments to address regional transportation issues. Its members include six counties (Imperial, Los Angeles, Orange, Riverside, San Bernardino, and Ventura) and 191 cities in an area covering more than 38,000 square miles. As the federally designated Metropolitan Planning Organization and the State‐designated Regional Transportation Planning Agency, SCAG is responsible for developing long‐range regional transportation plans, including sustainable communities strategy and growth forecast components, regional transportation improvement programs, regional housing needs allocations, and a portion of the South Coast Air Quality Management District plans.

Local
City of Santa Clarita. The project is located in Santa Clarita. As such, the Circulation Element of the City of Santa Clarita General Plan2 and Transportation Analysis Updates in Santa Clarita3 are the guidance documents for the City of Santa Clarita (City) transportation system. These guidelines are intended to ensure that the traffic impacts of a development proposal on the existing and/or planned major street system are adequately addressed. Transportation Analysis Updates in Santa Clarita states that intersections where a project would add 50 or more net new trips during the a.m. and p.m. peak hours should be included in a Local Transportation Assessment (LTA).4

4/28/22 «P:\HAV2001\Traffic\Transportation Memo2.docx» 3 Environmental Setting
Existing Circulation System
Bouquet Canyon Road is a five‐lane, north‐south roadway (three northbound lanes and three southbound lanes) along the project frontage. Bouquet Canyon Road is classified as a Major Highway in the Circulation Element of the City of Santa Clarita General Plan.1 A sidewalk is provided on the west side of the street. On‐street parking is permitted in select locations on the west side of the street.

Impact Analysis
a. Would the project conflict with a program, plan, ordinance, or policy addressing the circulation system, including transit, roadway, bicycle and pedestrian facilities? Less Than Significant Impact. In order to assess the impact of the project on the surrounding circulation system, vehicle trips were generated for temporary construction activities based on the anticipated number of workers and trucks, as well as for typical operations of the project.

Construction of the project is anticipated to take approximately 66 weeks and will include the following five phases (daily worker and truck estimates and phase durations):
 Phase 1: Site Preparation (8 workers per day for 1 week)  Phase 2: Grading (10 workers per day for 1 week)
 Phase 3: Building Construction (32 workers and 7 vendor trucks per day for 58 weeks)  Phase 4: Paving (15 workers per day for 3 weeks)
 Phase 5: Architectural Coating (6 workers per day for 3 weeks) It is assumed that workers would arrive at the site in the a.m. peak hour and depart the site during the p.m. peak hour. Truck trips are anticipated to occur throughout the day. A passenger car equivalent (PCE) factor of 2.0 has been applied to the trucks.

Tables A and B (all tables provided in Attachment B) present the construction and operational trip generation for the project.

As shown in Table A, Phase 3 (Building Construction) is the period of construction with the highest trip generation. Over approximately 58 weeks, Phase 3 is anticipated to generate 92 average daily trips (ADT), including 36 trips (34 inbound and 2 outbound) in the a.m. peak hour and 36 trips (2 inbound and 34 outbound) in the p.m. peak hour, in PCEs. All other construction phases would generate 30 or fewer ADT, including 15 or fewer peak‐hour trips, in PCEs.

1 City of Santa Clarita. 2011. Circulation Element. City of Santa Clarita General Plan. June. Website:
https://www.codepublishing.com/CA/SantaClarita/html/SantaClaritaGP/4%20‐%20Circulation%20 Element.pdf (accessed December 2020).
4/28/22 «P:\HAV2001\Traffic\Transportation Memo2.docx» 4 The Institute of Transportation Engineers (ITE) Trip Generation Manual, 11th Edition,1 is a nationally recognized source for estimating site‐specific trip generation. The ITE trip rates for Land Use Code 221 (Multifamily Housing [Mid‐Rise]), Land Use Code 822 (Strip Retail Plaza), and Land Use Code 492 (Health/Fitness Club) were applied to the project uses. As shown on Table B, the project has the potential to generate 636 ADT, including 32 trips (15 inbound and 17 outbound) in the a.m. peak hour and 70 trips (37 inbound and 33 outbound) in the p.m. peak hour.

The project would generate a maximum of 36 peak‐hour trips for any period of construction and a maximum of 32 a.m. and 70 p.m. peak‐hour trips once the project is operational. According to Transportation Analysis Updates in Santa Clarita, intersections where a project would add 50 or more net new trips during the a.m. and p.m. peak hours should be included in an LTA.2 The project would not generate 50 or more trips during both peak hours, and the project would not contribute 50 or more peak‐hour trips to any surrounding intersections. As such, the project is not anticipated to result in any LOS or operational deficiencies to the surrounding circulation system based on its low number of trips for temporary construction and typical operations.

The project would not make any changes to the public right‐of way in the project vicinity or generate a substantial number of daily or peak‐hour vehicle trips for construction or typical operations to warrant modifications to any transportation facilities (e.g., vehicular, transit, bicycle, or pedestrian). The project would not preclude alternative modes of transportation or facilities (e.g., transit, bicycle, or pedestrian). Therefore, the project would not conflict with the Circulation Element of the City of Santa Clarita General Plan. No mitigation is required. b. Would the project conflict or be inconsistent with CEQA Guidelines Section 15064.3, Subdivision (b)?
Less Than Significant Impact. State CEQA Guidelines Section 15064.3, subdivision (b), states that transportation impacts for land use projects are to be measured by evaluating the project’s VMT or the amount and distance of automobile travel attributable to the project, as outlined in the following:

Vehicle miles traveled exceeding an applicable threshold of significance may indicate a significant impact. Generally, projects within one‐half mile of either an existing major transit stop or a stop along an existing high‐quality transit corridor should be presumed to cause a less than significant transportation impact.

The OPR Technical Advisory and Transportation Analysis Updates in Santa Clarita both provide guidance for screening land use projects from a detailed VMT analysis and the presumption of a less than significant transportation impact, such as project size, locally serving retail use, and project located in a low VMT area.

1 Institute of Transportation Engineers. 2021. Trip Generation Manual. 11th ed. 2 City of Santa Clarita. 2020. Transportation Analysis Updates in Santa Clarita. May. Website: https://santa‐ clarita.com/Home/ShowDocument?id=18536 (accessed December 2020). 4/28/22 «P:\HAV2001\Traffic\Transportation Memo2.docx» 5 Transportation Analysis Updates in Santa Clarita recommends that locally serving retail uses (less than 50,000 sf) and residential uses located in a low VMT area (a City‐identified area that is already 15 percent below the baseline VMT) are screened from a VMT analysis.1 The project includes 10,293.5 sf of locally serving retail use (7,2661 sf of first‐floor retail space and a 3,027.4 sf yoga studio) and is located in a low VMT area (as shown in Figure 5 of Transportation Analysis Updates in Santa Clarita [provided in Attachment C]). Because the project meets the City’s VMT screening criteria, it is not subject to a VMT analysis and is presumed to have a less than significant transportation impact.

As such, the proposed would not conflict or be inconsistent with State CEQA Guidelines Section 15064.3(b). Potential impacts would be less than significant, and no mitigation is required. c. Would the project substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? Less Than Significant Impact. Regional access to the project is provided by Bouquet Canyon Road.

Site access is provided via an existing full‐access driveway on Bouquet Canyon Road. Access would not change as part of the project. As such, the project would not substantially increase hazards for vehicles due to a geometric design feature or incompatible uses, and impacts would be less than significant. No mitigation is required.
d. Would the project result in inadequate emergency access? Less Than Significant Impact. Site access would not change as part of the project and would continue to be provided from a full‐access driveway on Bouquet Canyon Road. Since the project would not modify the existing configuration of the driveway along Bouquet Canyon Road, emergency access to the site would not be affected. Therefore, impacts associated with emergency access would be less than significant. No mitigation is required.

MEMORANDUM
DATE: August 9, 2023
TO: Robert Neman, Harvard 826 Property, LLC
FROM: Jason Lui, Associate/Senior Noise Specialist
SUBJECT: Noise and Vibration Impact Analysis Memorandum for the proposed Promenade Flats Project at 26135 Bouquet Canyon Road in Santa Clarita, California

INTRODUCTION
This noise and vibration impact analysis has been prepared to evaluate the potential noise and vibration impacts associated with the proposed Promenade Flats Project in Santa Clarita, California (project). This report is intended to satisfy the City of Santa Clarita (City) requirement and the California Environmental Quality Act (CEQA) for a project‐specific noise and vibration impact analysis by examining the impacts of the proposed uses on the project site and determining whether reduction measures would be required to reduce noise and vibration impacts.

PROJECT LOCATION
The project site is located along the west side of Bouquet Canyon Road, north of Magic Mountain Parkway and south of Cinema Drive at 26135 Bouquet Canyon Road (Assessor’s Parcel Number 2811‐003‐018) in the community of Valencia. The project site has a Mixed Use Corridor (MXC) zoning designation. Figure 1, below, shows the project location.

PROJECT DESCRIPTION
The proposed project would remove a portion of the existing parking lot to accommodate a new four‐story, mixed‐use building on 1.2 acres. The proposed project would include a total of 15,741.50 square feet (ft) of commercial use consisting of a 7,266.10 sf first‐floor retail space, a 3,027.40 sf rooftop yoga studio, and the existing 5,448 sf International House of Pancakes (IHOP) restaurant. In addition to the new commercial uses, the proposed building would include four live/work units and 26 one‐bedroom units on floors two through four. Additionally, a new 14,359 sf (0.33 acre) parking lot would be constructed on an adjacent vacant parcel to offset the parking that would be removed as part of the project. Construction of the proposed project would start in August 2022 and would be completed in approximately 16 months. Figure 2 shows the site plan. Figures 3 through 5 show the floor plans of the proposed mixed‐use building.

CHARACTERISTICS OF SOUND
Sound is increasing to such disagreeable levels in the environment that it can threaten quality of life.

Noise is usually defined as unwanted sound. Noise consists of any sound that may produce physiological or psychological damage and/or interfere with communication, work, rest, recreation, and sleep.

To the human ear, sound has two significant characteristics: pitch and loudness. Pitch is generally an annoyance, while loudness can affect the ability to hear. Pitch is the number of complete vibrations, or cycles per second, of a wave resulting in the tone’s range from high to low. Loudness is the strength of a sound that describes a noisy or quiet environment and is measured by the amplitude of the sound wave. Loudness is determined by the intensity of the sound waves combined with the reception characteristics of the human ear. Sound intensity refers to how hard the sound wave strikes an object, which in turn produces the sound’s effect. This characteristic of sound can be precisely measured with instruments. The analysis of a project defines the noise environment of the project area in terms of sound intensity and its effect on adjacent sensitive land uses.

Measurement of Sound
Sound intensity is measured through the A‐weighted scale to correct for the relative frequency response of the human ear. That is, an A‐weighted noise level de‐emphasizes low and very high frequencies of sound similar to the human ear’s de‐emphasis of these frequencies. Decibels, unlike the linear scale (e.g., inches or pounds), are measured on a logarithmic scale, which is a scale based on powers of 10.

For example, 10 decibels (dB) is 10 times more intense than 0 dB, 20 dB is 100 times more intense than 0 dB, and 30 dB is 1,000 times more intense than 0 dB. Thirty decibels (30 dB) represents 1,000 times as much acoustic energy as 0 dB. The decibel scale increases as the square of the change, representing the sound pressure energy. A sound as soft as human breathing is about 10 times greater than 0 dB. The decibel system of measuring sound gives a rough connection between the physical intensity of sound and its perceived loudness to the human ear. A 10 dB increase in sound level is perceived by the human ear as only a doubling of the loudness of the sound. Ambient sounds generally range from 30 dB (very quiet) to 100 dB (very loud).

Sound levels are generated from a source, and their decibel level decreases as the distance from that source increases. Sound dissipates exponentially with distance from the noise source. For a single point source, sound levels decrease approximately 6 dB for each doubling of distance from the source. This drop‐off rate is appropriate for noise generated by stationary equipment. If noise is produced by a line source (e.g., highway traffic or railroad operations), the sound decreases 3 dB for each doubling of distance in a hard‐site environment; however, line source noise in a relatively flat environment with absorptive vegetation decreases 4.5 dB for each doubling of distance.

There are many ways to rate noise for various time periods, but an appropriate rating of ambient noise affecting humans also accounts for the annoying effects of sound. The equivalent continuous sound level (Leq) is the total sound energy of time‐varying noise over a sample period. However, the predominant rating scales for human communities in the State of California are Leq and the Community Noise Equivalent Level (CNEL) or the day‐night average noise level (Ldn) based on A‐weighted decibels (dBA). CNEL is the time‐varying noise over a 24‐hour period, with a 5 dBA 10/9/23 «P:\HAV2001\Noise\Product\Noise Memo_20231009.docx» 8 weighting factor applied to the hourly Leq for noises occurring from 7:00 p.m. to 10:00 p.m. (defined as relaxation hours), and a 10 dBA weighting factor applied to noises occurring from 10:00 p.m. to 7:00 a.m. (defined as sleeping hours). Ldn is similar to the CNEL scale but without the adjustment for events occurring during relaxation hours. CNEL and Ldn are within 1 dBA of each other and are normally interchangeable. The City uses the CNEL noise scale for long‐term noise impact assessment.

Other noise rating scales of importance during assessment of the annoyance factor include the maximum noise level (Lmax), which is the highest exponential time‐averaged sound level that occurs during a stated time period. The noise environments discussed in this analysis for short‐term noise impacts are specified in terms of maximum levels denoted by Lmax, which reflects peak operating conditions and addresses the annoying aspects of intermittent noise. It is often used together with another noise scale, or noise standards in terms of percentile noise levels, in noise ordinances for enforcement purposes. For example, the L10 noise level represents the noise level exceeded 10 percent of the time during a stated period. The L50 noise level represents the median noise level.

Half the time the noise level exceeds this level, and half the time it is less than this level. The L90 noise level represents the noise level exceeded 90 percent of the time and is considered the background noise level during a monitoring period. For a relatively constant noise source, Leq and L50 are approximately the same.

Noise impacts can be described in three categories. The first category includes audible impacts, which refers to increases in noise levels noticeable to humans. Audible increases in noise levels generally refer to a change of 3 dB or greater because this level has been found to be barely perceptible in exterior environments. The second category, potentially audible, refers to a change in the noise level between 1 dB and 3 dB. This range of noise levels has been found to be noticeable only in laboratory environments. The last category includes changes in noise levels of less than 1 dB, which are inaudible to the human ear. Only audible changes in existing ambient or background noise levels are considered potentially significant.

Physiological Effects of Noise
Physical damage to human hearing begins at prolonged exposure to noise levels higher than 85 dBA.

Exposure to high noise levels affects the entire system, with prolonged noise exposure in excess of 75 dBA increasing body tensions, thereby affecting blood pressure and functions of the heart and the nervous system. In comparison, extended periods of noise exposure above 90 dBA would result in permanent cell damage. When the noise level reaches 120 dBA, a tickling sensation occurs in the human ear, even with short‐term exposure. This level of noise is called the threshold of feeling. As the sound reaches 140 dBA, the tickling sensation is replaced by the feeling of pain in the ear (the threshold of pain). A sound level of 160–165 dBA will result in dizziness or loss of equilibrium. The ambient or background noise problem is widespread and generally more concentrated in urban areas than in outlying, less developed area. Table A lists definitions of acoustical terms, and Table B shows common sound levels and their sources.

Community Noise
Equivalent Level, CNEL
The 24‐hour A‐weighted average sound level from midnight to midnight, obtained after the addition of 5 dBA to sound levels occurring in the evening from 7:00 PM to 10:00 PM and after the addition of 10 dBA to sound levels occurring in the night between 10:00 PM and 7:00 AM.

Lmax, Lmin The maximum and minimum A‐weighted sound levels measured on a sound level meter, during a designated time interval, using fast time averaging.

Ambient Noise Level The all‐encompassing noise associated with a given environment at a specified time, usually a composite of sound from many sources from many directions, near and far; no particular sound is dominant.

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

FUNDAMENTALS OF VIBRATION
Vibration refers to ground‐borne noise and perceptible motion. Ground‐borne vibration is almost exclusively a concern inside buildings and is rarely perceived as a problem outdoors. Outdoors, the 10/9/23 «P:\HAV2001\Noise\Product\Noise Memo_20231009.docx» 10 motion may be discernible, but without the effects associated with the shaking of a building, there is less adverse reaction. Vibration energy propagates from a source through intervening soil and rock layers to the foundations of nearby buildings. The vibration then propagates from the foundation throughout the remainder of the structure. Building vibration may be perceived by occupants as the motion of building surfaces, the rattling of items on shelves or hanging on walls, or a low‐frequency rumbling noise. The rumbling noise is caused by the vibration of walls, floors, and ceilings that radiate sound waves. Annoyance from vibration often occurs when the vibration exceeds the threshold of perception by 10 vibration velocity decibels (VdB) or less. This is an order of magnitude below the damage threshold for normal buildings.

Typical sources of ground‐borne vibration are construction activities (e.g., blasting, pile driving, and operating heavy‐duty earthmoving equipment), steel‐wheeled trains, and occasional traffic on rough roads. Ground‐borne vibration and noise from these sources are usually localized to areas within approximately 100 feet (ft) from the vibration source, although there are examples of ground‐borne vibration causing interference out to distances greater than 200 ft (FTA 2018). When roadways are smooth, vibration from traffic, even heavy trucks, is rarely perceptible. It is assumed for most projects that the roadway surface will be smooth enough that ground‐borne vibration from street traffic will not exceed the impact criteria; however, both construction of a project and freight train operations on railroad tracks could result in ground‐borne vibration that may be perceptible and annoying.

Ground‐borne noise is not likely to be a problem because noise arriving via the normal airborne path will usually be greater than ground‐borne noise. Ground‐borne vibration has the potential to disturb people and damage buildings. Although it is very rare for train‐induced ground‐borne vibration to cause cosmetic building damage, it is not uncommon for heavy‐duty construction processes (e.g., blasting and pile driving) to cause vibration of sufficient amplitudes to damage nearby buildings (FTA 2018). Ground‐borne vibration is usually measured in terms of vibration velocity, either the root‐ mean‐square (RMS) velocity or peak particle velocity (PPV). The RMS velocity is best for characterizing human response to building vibration, and PPV is used to characterize potential for damage. Decibel notation acts to compress the range of numbers required to describe vibration.

Vibration velocity level in decibels is defined as the following:

Lv = 20 log10 [V/Vref]
where Lv is the VdB, V is the RMS velocity amplitude, and Vref is the reference velocity amplitude, or 1 x 10‐6 inches/second (in/sec) used in the United States.

Noise. The construction noise criteria included in the Federal Transit Administration (FTA) Transit Noise and Vibration Impact Assessment Manual (2018) was used to evaluated potential construction noise impacts because Section 11.44.080 of the City’s Municipal Code does not have daytime construction noise level limits for activities that occur within the specified hours. Table C shows the FTA’s Detailed Assessment Daytime Construction Noise Criteria based on the composite noise levels for each construction phase.

Vibration. Vibration standards included in the Federal Transit Administration (FTA) Transit Noise and Vibration Impact Assessment Manual (2018) are used in this analysis for ground‐borne vibration impacts on human annoyance. Table D provides the criteria for assessing the potential for interference or annoyance from vibration levels in a building.

The criteria for environmental impact from ground‐borne vibration and noise are based on the maximum levels for a single event. Table E lists the potential vibration building damage criteria associated with construction activities, as suggested in the Transit Noise and Vibration Impact Assessment Manual (FTA 2018). FTA guidelines show that a vibration level of up to 102 VdB (equivalent to 0.5 in/sec in PPV [FTA 2018]) is considered safe for buildings consisting of reinforced concrete, steel, or timber (no plaster), and would not result in any construction vibration damage.

For non‐engineered timber and masonry buildings, the construction building vibration damage criterion is 94 VdB (0.2 in/sec in PPV).

Noise Element. The City’s General Plan Noise Element lists the objectives and policies required to meet the City’s noise‐related goals. The following lists the applicable goals, objectives, and policies, for the proposed project.
 Goal N1: A healthy and safe noise environment for Santa Clarita Valley residents, employees, and visitors.
○ Objective N1.1: Protect the health and safety of the residents of the Santa Clarita Valley by the elimination, mitigation, and prevention of significant existing and future noise levels. ■ Policy N1.1.1. Use the Noise and Land Use Compatibility Guidelines contained in Table F (Exhibit N‐8 in the Noise Element of the General Plan), which are consistent with State guidelines, as a policy basis for decisions on land use and development proposals related to noise.
■ Policy N1.1.4. Control noise sources adjacent to residential, recreational, and community facilities, and those land uses classified as noise sensitive.  Goal N2: Protect residents and sensitive receptors from traffic‐generated noise. ○ Objective N2.1: Prevent and mitigate adverse effects of noise generated from traffic on arterial streets and highways through implementing noise reduction standards and programs.
■ Policy N2.1.1. Encourage owners of existing noise‐sensitive uses, and require owners of proposed noise sensitive land uses, to construct sound barriers to protect users from significant noise levels, where feasible and appropriate. ■ Policy N2.1.2. Encourage the use of noise absorbing barriers, where appropriate.  Goal N3: Protect residential neighborhoods from excessive noise. ○ Objective N3.1: Prevent and mitigate significant noise levels in residential neighborhoods. ■ Policy N3.1.1. Require that developers of new single‐family and multi‐family residential neighborhoods in areas where the ambient noise levels exceed 60 dBA CNEL provide mitigation measures for the new residences to reduce interior noise levels to 45 dBA CNEL, based on future traffic and railroad noise levels. ■ Policy N3.1.2. Require that developers of new single‐family and multi‐family residential neighborhoods in areas where the projected noise levels exceed 65 dBA CNEL provide mitigation measures (which may include noise barriers, setbacks, and site design) for new residences to reduce outdoor noise levels to 65 dBA CNEL, based on future traffic conditions. This requirement would apply to rear yards areas for single‐family developments, and to private open space and common recreational and open space areas for multi‐family developments.

Through enforcement of the applicable Noise Ordinance, protect residential neighborhoods from noise generated by machinery or activities that produce significant discernable noise exceeding recommended levels for residential uses. ■ Policy N3.1.4. Require that those responsible for construction activities develop techniques to mitigate or minimize the noise impacts on residences, and adopt standards that regulate noise from construction activities that occur in or near residential neighborhoods.
■ Policy N3.1.9. Implement a buyer and renter notification program for new residential developments where appropriate, to educate and inform potential buyers and renters of the sources of noise in the area and/or new sources of noise that may occur in the future. As determined by the reviewing authority, notification may be appropriate in the following areas:
a. Within one mile of Six Flags Magic Mountain theme park, potential buyers and renters should receive notice that noise may occasionally be generated from this facility and that the frequency and loudness of noise events may change over time. b. Within 1,000 feet of the railroad, potential buyers and renters should receive notice that noise may occasionally be generated from this facility and that the frequency and loudness of noise events may change over time.
c. Within 200 feet of commercial uses in mixed‐use developments, potential buyers and renters should receive notice that the commercial uses within the mixed‐use developments may generate noise in excess of levels typically found in residential areas, that the commercial uses may change over time, and the associated noise levels and frequency of noise events may change along with the use. d. Within 1,000 feet of the Saugus Speedway, in the event speedway operations are resumed in the future.

Municipal Code. Section 11.44.040 of the City’s Municipal Code has established daytime and nighttime exterior noise limits in regions designated as residential, and commercial and manufacturing, as shown in Table G.

EXISTING SETTING
Land Uses in the Project Vicinity
Land uses surrounding the proposed building include residences to the west and commercial uses to the north, east, and south. Land uses surrounding the new parking lot include residences to the north and southeast and commercial uses to the east, south, and west. Bouquet Canyon Road and the Metrolink rail are located east of the project.

Overview of the Existing Noise Environment
Transportation facilities make up the primary existing noise sources in the project area. Traffic on Bouquet Canyon Road and other roadways in the vicinity are a steady source of ambient noise. The Metrolink rail line to the east is a source of intermittent noise. Other sources of noise in the project area include commercial activity.

Ambient Noise Measurements
Short‐Term Noise Measurements
Short‐term (15‐minute) noise level measurements were conducted on January 25 and 26, 2021, using a Larson Davis Model 831 Type 1 sound level meter. Table H shows the results of the short‐ term noise level measurements along with a description of the measurement locations and noise sources that occurred during the measurement. As shown in Table H, the measured average noise levels in the project vicinity range from 51.8 to 69.1 dBA Leq, and the instantaneous maximum noise levels range from 66.4 to 84.0 dBA Lmax. Figure 6 shows the short‐term monitoring locations.

Long‐Term Noise Measurements
Two long‐term (24‐hour) noise level measurements were conducted from January 25 to January 26, 2021, using a Larson Davis Spark 706RC Dosimeter. Tables I and J show the hourly Leq, Lmax, and Lmin results from the long‐term noise level measurements, and Table K summarizes the long‐term noise level measurements. As shown in Table K, the noise levels on the project site range from 46.1 to

61.9 dBA Leq and calculated CNEL levels range from 60.4 to 62.0 dBA. Figure 6 shows the long‐term monitoring locations.

Existing Aircraft Noise
The Whiteman, Agua Dulce, and Van Nuys Airports are approximately 12.8 miles southwest, 13.8 miles northeast, and 14 miles south of the project site, respectively. Based on the airport influence area map in the Los Angeles County Airport Land Use Plan (Los Angeles County ALUC 2004), the project site is well beyond the airport influence areas for any of these airports.

Existing Traffic Noise
The Federal Highway Administration (FHWA) Highway Traffic Noise Prediction Model (FHWA‐RD‐77‐ 108) was used to evaluate highway traffic‐related noise conditions along roadway segments in the project vicinity. This model requires various parameters, including traffic volumes, vehicle mix, vehicle speed, and roadway geometry to compute typical equivalent noise levels during daytime, evening, and nighttime hours. The resultant noise levels are weighted and summed over 24‐hour periods to determine the CNEL values. The standard vehicle mix for Southern California roadways was used for traffic on these roadway segments. The 2008 average daily traffic (ADT) volume of 37,650 on Bouquet Canyon Road was obtained from the City’s Traffic Flow Map (City of Santa Clarita 2013). The City’s Traffic Flow Map show that the ADT volumes decreased greatly from 2008 to 2013 and were not projected to the existing 2021 year. For the reasons described above, the existing 2021 ADT volumes were assumed to be equivalent to the 2008 ADT volumes. Table L shows the modeled 24‐hour CNEL levels for the existing conditions. These noise levels represent the worst‐ case scenario, which assumes no shielding is provided between the traffic and the location where the noise contours are drawn. The specific assumptions used in developing these noise levels and model printouts are provided in Attachment B.

As shown in Table L, traffic noise levels along Bouquet Canyon Road directly adjacent to the project site are moderately high, with the 70, 65, and 60 dBA CNEL noise contours extending 112 ft, 344 ft, and 1,084 ft, respectively, from the roadway centerline. 10/9/23 «P:\HAV2001\Noise\Product\Noise Memo_20231009.docx» 21 Table L: Existing Traffic Noise Levels

IMPACTS
Short‐Term Construction Noise Impacts
Two types of short‐term noise impacts would occur during project construction. The first type would be from construction crew commutes and the transport of construction equipment and materials to the project site and would incrementally raise noise levels on roadways leading to the site. The pieces of construction equipment for construction activities would move on site, would remain for the duration of each construction phase, and would not add to the daily traffic volume in the project vicinity. Although there would be a relatively high single‐event noise exposure potential causing intermittent noise nuisance (passing trucks at 50 ft would generate up to a maximum of 84 dBA), the effect on longer‐term ambient noise levels would be small because the number of daily construction‐related vehicle trips is small compared to existing daily traffic volume on Bouquet Canyon Road. The demolition phase would generate the most trips of all of the construction phases, at a Passenger Car Equivalent (PCE) of 260 trips per day based on the California Emissions Estimator Model (Version 2022.1). Based on Table L, Bouquet Canyon Road has an estimated existing ADT volume of 37,650 adjacent to the project site. Based on the information above, construction‐related traffic noise would increase by 0.03 dBA. A noise level increase of less than 3 dBA would not be perceptible to the human ear in an outdoor environment. Therefore, no short‐term, construction‐ related impacts associated with worker commutes and transport of construction equipment and material to the project site would occur, and no noise reduction measures would be required.

The second type of short‐term noise impact is related to noise generated from construction activities. The proposed project anticipates site preparation, grading, building construction, paving, and architectural coating phases of construction. Construction is performed in discrete steps, each of which has its own mix of equipment and, consequently, its own noise characteristics. These various sequential phases change the character of the noise generated on a project site. Therefore, the noise levels vary as construction progresses. Despite the variety in the type and size of construction equipment, similarities in the dominant noise sources and patterns of operation allow construction‐related noise ranges to be categorized by work phase. Table M lists the Lmax recommended for noise impact assessments for typical construction equipment included in the FHWA’s Highway Construction Noise Handbook (2006), based on a distance of 50 ft between the equipment and a noise receptor.

Note: The noise levels reported in this table are rounded to the nearest whole number. 1 The usage factor is the percentage of time during a construction noise operation that a piece of construction equipment is operating at full power. 2 Maximum noise levels were developed based on Specification 721.560 from the CA/T program to be consistent with the City of Boston, Massachusetts, Noise Code for the “Big Dig” project.

CA/T = Central Artery/Tunnel
FHWA = Federal Highway Administration
ft = foot/feet
Lmax = maximum instantaneous noise level
Typical noise levels range up to 88 dBA Lmax at 50 ft during the noisiest construction phases. The site preparation and grading phase tends to generate the highest noise levels because the noisiest construction equipment is earthmoving equipment. Earthmoving equipment includes excavating machinery such as backhoes, bulldozers, excavators, and front‐end loaders. Earthmoving and compacting equipment include compactors, scrapers, and graders. Typical operating cycles for these types of construction equipment may involve 1 to 2 minutes of full‐power operation followed by 3 to 4 minutes at lower power settings.

Project construction is expected to require the use of a grader, bulldozer, and water truck/pickup truck. Noise associated with the use of construction equipment is estimated to be between 55 dBA Lmax and 85 dBA Lmax at a distance of 50 ft from the active construction area for the site preparation and grading phase. As shown in Table M, the maximum noise level generated by a grader is assumed to be approximately 85 dBA Lmax at 50 ft from the grader. The dozer would generate approximately 85 dBA Lmax at 50 ft. The maximum noise level generated by a water truck/pickup truck is approximately 55 dBA Lmax at 50 ft. Each doubling of the sound sources with equal strength increases the noise level by 3 dBA. Assuming that each piece of construction equipment operates at some distance from the other equipment, the worst‐ case combined noise level during construction would 10/9/23 «P:\HAV2001\Noise\Product\Noise Memo_20231009.docx» 23 be 88 dBA Lmax at a distance of 50 ft from the active construction area. Based on a usage factor of 40 percent, the worst‐case combined noise level during construction would be 84 dBA Leq at a distance of 50 ft from the active construction area.

The closest residences are located approximately 175 ft west from the center of the proposed building and approximately 75 ft north from the center of the new parking area, which may be subject to short‐term construction noise reaching 77 dBA Lmax (73 dBA Leq) and 82 dBA Lmax (78 dBA Leq), respectively. Construction noise is temporary and would stop once project construction is completed. The project would be required to comply with the construction hours allowed under the City’s Municipal Code Noise Ordinance, and standard conditions for construction listed below would minimize construction noise. Furthermore, construction related noise levels would be below the FTA noise level standard of 80 dBA Leq for residential uses. Therefore, no noise impacts from construction activities would occur, and no noise reduction measures are required.  The construction contractor shall limit construction activities to between the hours of 7:00 a.m. and 7:00 p.m. Monday through Friday and between the hours of 8:00 a.m. and 6:00 p.m. on Saturday. No construction shall be permitted outside of these hours or on Sundays and New Year’s Day, Independence Day, Thanksgiving, Christmas, Memorial Day, and Labor Day.  During all project site excavation and grading, the project contractors shall equip all construction equipment, fixed or mobile, with properly operating and maintained mufflers consistent with manufacturers’ standards.
 The construction contractor shall locate equipment staging in areas that will create the greatest distance between construction‐related noise sources and most noise‐sensitive receptors nearest the project site during all project construction.
 The construction contractor shall place all stationary construction equipment so that the emitted noise is directed away from the sensitive receptors nearest the project site.

Short‐Term Construction Vibration Impacts
This construction vibration impact analysis discusses the level of human annoyance using vibration levels in VdB and will assess the potential for building damages using vibration levels in PPV (in/sec) because vibration levels calculated in RMS are best for characterizing human response to building vibration whereas vibration level in PPV is best used to characterize potential for damage. As shown previously in Table E, the FTA guidelines indicate that a vibration level up to 102 VdB (equivalent to

0.5 PPV [in/sec]) is considered safe for buildings consisting of reinforced concrete, steel, or timber (no plaster) and would not result in any construction vibration damage (FTA 2018). For a non‐ engineered timber and masonry building, the construction vibration damage criterion is 94 VdB (0.2 PPV [in/sec]). For a fragile building, the construction vibration damage criterion is 90 VdB (0.12 PPV [in/sec]).
10/9/23 «P:\HAV2001\Noise\Product\Noise Memo_20231009.docx» 24 Table N shows the reference vibration levels at a distance of 25 ft for each type of standard construction equipment from the FTA’s Transit Noise and Vibration Impact Assessment Manual (2018). Outdoor site preparation and grading for the proposed project are expected to require the use of a small bulldozer (with rubber tires) and loaded trucks, which would generate ground‐borne vibrations of up to 58 VdB (0.003 PPV [in/sec]) and 86 VdB (0.076 PPV [in/sec]), respectively, when measured at 25 ft.

The greatest vibration levels are anticipated to occur during the site preparation and grading phase.

All other phases are expected to result in lower vibration levels. The distance to the nearest buildings for vibration impact analysis is measured between the nearest off‐site buildings and the project boundary (assuming the construction equipment would be used at or near the project boundary), because vibration impacts normally occur within the buildings. An exception to this would be the location of loaded trucks. Loaded trucks would be limited to certain areas on the project site and would not operate at the project construction boundary.

The following provides the formula for vibration transmission:

As shown in Table O, the closest residential buildings are located west of the proposed building and southeast of the proposed parking lot site and would experience vibration levels of up to 84 VdB (0.058 PPV [in/sec]) and 93 VdB (0.164 PPV [in/sec]), respectively. These vibration levels have the potential to result in community annoyance because vibration levels would exceed the FTA annoyance threshold of 78 VdB for daytime residences.

would not have the potential to result in building damage because vibration levels would not exceed the FTA damage threshold of 94 VdB (0.2 PPV [in/sec]) since the residential buildings would be constructed of non‐engineered timber and masonry.

Also, Table O shows that the closest commercial buildings, which are located north and east of the proposed building and west of the proposed parking lot site, would experience vibration levels of up to 84 VdB (0.058 PPV [in/sec]). This vibration level would not have the potential to result in community annoyance because the vibration levels would exceed the FTA annoyance threshold of 84 VdB for buildings not as sensitive to vibration. In addition, this vibration level would not have the potential to result in building damage because vibration levels would not exceed the FTA damage threshold of 94 VdB (0.2 PPV [in/sec]) since the commercial buildings would be constructed of non‐ engineered timber and masonry. Other adjacent buildings to the project site are farther away and would experience lower vibration levels. Therefore, no construction vibration impacts would occur, and no vibration reduction measures are required.

Long‐Term Aircraft Noise Impacts
As discussed above, the Whiteman, Agua Dulce, and Van Nuys Airports are approximately 12.8 miles southeast, 13.8 miles northeast, and 14 miles south of the project site, respectively. Based on the airport influence area map for these airports in the Los Angeles County Airport Land Use Plan (Los Angeles County ALUC 2004), the project site is well beyond the airport influence area for noise impacts. Therefore, the project would not expose people working or residing in the project area to excessive noise levels.
10/9/23 «P:\HAV2001\Noise\Product\Noise Memo_20231009.docx» 26 Long‐Term Traffic Noise Impacts
The proposed project is estimated to generate an ADT volume of 636 based on the proposed 7,266.10 sf of retail, 3,027.40 sf of rooftop yoga studio (health/fitness club), and 30 multifamily residential units from the Institute of Transportation Engineers (ITE) Trip Generation Manual, 11th Edition (2021). As discussed above, the existing 2021 ADT volume on Bouquet Canyon Road is assumed to be 37,650. It takes a doubling of traffic to increase traffic noise levels by 3 dBA. The project‐related traffic would increase traffic noise along Bouquet Canyon Road by up to 0.07 dBA. A noise level increase of less than 3 dBA would not be perceptible to the human ear in an outdoor environment. Therefore, no traffic noise impacts from project‐related traffic on off‐site sensitive receptors would occur, and no noise reduction measures are required.

Land Use Compatibility
The proposed project’s on‐site uses were assessed based on the City’s exterior noise standard of 65 dBA CNEL contained in the Noise Element of the City’s General Plan and an interior noise standard of 45 dBA CNEL, which is consistent with the State’s noise insulation standards.

Exterior Noise Levels
As discussed above, exterior noise levels in the project area include traffic on Bouquet Canyon Road, train noise from the Metrolink rail line, and commercial activity. The project site is located well beyond the airport influence area of the closest airports and the contribution of aircraft noise in the project area would be minimal to negligible. The long‐term noise level measurements at LT‐1 and LT‐2 are composite noise levels of all the noise sources in the project area described above, and the calculated CNEL levels at LT‐1 and LT‐2 were 62.0 and 60.4 dBA, respectively.

To assess the future exterior noise levels on the project site, the composite existing exterior noise level at the ground floor of Receptors R‐1 and R‐2 were calculated based on traffic noise on Bouquet Canyon Road and train noise from the Metrolink rail line to ensure that it is consistent with the measured noise level. Figure 7 shows the modeled receptor locations. Receptor R‐1 represents the area east of the proposed building, which is in the approximate location of LT‐1. Receptor R‐2 represents the area west of the proposed building, which is in the approximate location of LT‐2.

Existing traffic noise levels on Bouquet Canyon Road are shown in Table L, which has a traffic noise level of 65 dBA CNEL at 344 ft from the roadway centerline. The existing commercial buildings north, east, and south of the project site would provide an estimated traffic noise reduction of 5 dBA and 3 dBA at Receptors R‐1 and R‐2, respectively. The existing train noise was estimated to be 62.4 dBA CNEL at 50 ft based on a reference noise level of 57 dBA Leq at 50 ft with 21 daytime trips, 4 evening trips, and 5 nighttime trips. The existing commercial buildings north, east, and south of the project site would provide an estimated train noise reduction of 6 dBA and 4 dBA at Receptors R‐1 and R‐2, respectively.

Table P shows that the calculated existing composite noise levels at Receptors R‐1 and R‐2 are 63 and 61 dBA CNEL, respectively, which are levels considered in agreement with the measured noise levels at LT‐1 and LT‐2. Table C‐1 in Attachment C shows the detailed noise calculations for the existing ground floor noise levels at Receptors R‐1 and R‐2.

Interior noise levels were calculated using an exterior‐to interior noise reduction of 12 dBA based on the EPA’s Protective Noise Levels (EPA 1978) and standard construction in California (warm climate) with a combination of exterior walls, doors, and windows. 2 Numbers shown in bold exceed the interior noise standard of 45 dBA CNEL.

dBA = A‐weighted decibels

The existing and future upper floor exterior noise levels were then calculated at Receptors R‐1 and R‐2 without shielding from the existing commercial buildings to the north, east, and south because the proposed residences would be located on the upper floors (floors 2 through 4) and the existing commercial buildings would not provide any noise reduction. The future traffic volume on Bouquet Canyon Road was estimated to have an average daily traffic (ADT) volume of 45,000 based on an ADT capacity of 9,000 vehicles per lane from the General Plan Circulation Element (City of Santa Clarita 2011a) and an existing five‐lane divided roadway (three lanes in the northbound direction and two lanes in the southbound direction) on Bouquet Canyon Road in the project area. The future ADT volume of 45,000 would have a traffic noise level of 65 dBA CNEL at a distance of 411 ft based on the FHWA Traffic Noise Prediction Model (FHWA‐RD‐77‐108). This noise level represents the worst‐case scenario, which assumes no shielding is provided between the traffic and the location where the noise contours are drawn. The specific assumptions used in developing the noise level and model printout are provided in Attachment B.

Table P shows the existing and future upper floor exterior noise levels at R‐1 and R‐2. Tables C‐2 and C‐3 in Attachment C shows the detailed noise calculations for the existing and future upper floor noise levels at Receptors R‐1 and R‐2. As shown in Table P, future upper floor exterior noise levels at Receptors R‐1 and R‐2 are predicted to be 69.0 dBA CNEL and 65.0 dBA CNEL, respectively. The proposed outdoor private living areas (e.g., balconies or common outdoor areas) would have exterior noise levels that exceed the City’s exterior noise standard of 65 dBA CNEL for residential uses in the future as traffic increases. A minimum barrier height of 6 ft surrounding the private balconies of residential dwelling units and the rooftop terrace would provide a minimum noise reduction of 5 dBA and would reduce exterior noise levels to 65 dBA CNEL or below. In addition, the project would comply with Policy N3.1.9 in the Noise Element of the General Plan by providing notification to all potential buyers or renters of the residential dwelling units of noise sources in the area, new noise sources that may occur in the future, commercial uses that may generate noise in excess of levels for residential uses, that commercial uses may change over time, and that noise levels and frequency of noise events may change along with the change in commercial use because the proposed project would be located within 1,000 ft of the Metrolink rail line and within 200 ft of commercial uses. Therefore, no exterior noise impacts would occur with implementation of balcony barriers and rooftop terrace barriers and compliance with Policy N3.1.9 in the City’s General Plan Noise Element.

Interior noise levels were calculated using an exterior‐to interior noise reduction of 12 dBA based on the EPA’s Protective Noise Levels (EPA 1978) and standard construction in California (warm climate) with a combination of exterior walls, doors, and windows. 2 Numbers shown in bold exceed the interior noise standard of 45 dBA CNEL.

CNEL = Community Noise Equivalent Level

Interior Noise Levels
Table P shows the interior noise levels with windows and doors open for Receptors R‐1 and R‐2.

Interior noise levels with windows and doors open were calculated using an exterior‐to‐interior noise reduction of 12 dBA based on the United States Environmental Protection Agency (EPA) Protective Noise Levels (EPA 1978) and standard construction in California (warm climate) with a combination of exterior walls, doors, and windows. As shown in Table P, interior noise levels with windows and doors open would range from 53 to 57 dBA CNEL, which would exceed the interior noise standard of 45 dBA CNEL. Therefore, mechanical ventilation systems such as air conditioning would be required for all residential units so that windows and doors could remain closed for a prolonged period of time. Because the project plans show that air conditioning systems are included as part of the project, no additional measures are required.

Table P also shows that an exterior‐to‐interior noise reduction of 20 to 24 dBA is required to meet the interior noise standard of 45 dBA CNEL. To calculate and estimate the noise reduction provided by an exterior wall assembly, the transmission loss at the octave band frequencies for wall material by type is combined to provide an overall noise reduction. The rating of the wall and window or windows within the assembly will often be referred to as a sound transmission class (STC) rating.

The program INSUL was used to estimate the window ratings to ensure that compliance is achieved.

Based on wall details presented in the project plans, the following elements make up the assumed exterior wall assembly:
 7/8‐inch‐thick, three‐coat stucco
 One layer of 0.5‐inch‐thick plywood or oriented strand board (OSB)  One layer of 5/8‐inch‐thick gypsum board
 2‐inch x 6‐inch wood stud wall channels spaced at 16 inches and a minimum R‐19 fiberglass insulation
 One layer of 5/8‐inch‐thick gypsum board
In addition to the wall construction details, information from the VPI Quality Windows Endurance Series, which is energy and sound rated, was used to determine window STC ratings. The required window STC ratings and the composite noise level reduction are provided for the sensitive rooms based on the project floor plans. Attachment D provides the results of the INSUL model. 10/9/23 «P:\HAV2001\Noise\Product\Noise Memo_20231009.docx» 30 The results of the analysis indicated that for the living room of the corner units facing east towards Bouquet Canyon Road, windows and glass doors with a minimum rating of STC‐31 are required due to the high wall exposure area and high window‐to‐wall ratio. For all other noise‐sensitive rooms within the project site (i.e., living room and bedrooms), windows and glass doors with a minimum rating of STC‐28 would achieve interior noise levels of 45 dBA CNEL or below.

Long‐Term Off‐Site Stationary Noise Impacts
The project would be potentially exposed to stationary source noise impacts from truck deliveries and unloading activities, parking lot activities, and heating, ventilation, and air conditioning (HVAC) equipment. The following provides a detailed noise analysis and discussion of each stationary noise source.

Truck Delivery and Truck Unloading Activities
The project would include truck delivery and unloading activities associated with the first floor retail space. Truck delivery and truck unloading activities would occur in the designated parking space near the IHOP restaurant or near the south side of the proposed building. Existing truck delivery and truck unloading activities occur in the project area for the IHOP restaurant and the commercial uses to the south. Noise levels generated by truck deliveries and truck unloading activities from the proposed retail uses would occur at a similar location as the existing commercial uses to the south and would not increase the ambient noise environment in the project area. Therefore, no noise impacts from truck deliveries and truck unloading activities would occur, and no noise reduction measures are required.

Parking Lot Activity
The proposed project would include a total of 41 new parking spaces located on an adjacent parcel.

Noise generated from parking lot activities would include noise generated by vehicles traveling at slow speeds, engine start‐up noise, car door slams, car horns, car alarms, and tire squeals. The existing residences north of the new parking spaces are already exposed to noise levels generated from parking activities associated with their own parking spaces and from the commercial uses to the east. Noise levels generated by parking activities from the new parking spaces would not increase the ambient noise environment in the project area. Therefore, no noise impacts from parking activities would occur, and no noise reduction measures are required.

HVAC Equipment
The proposed project would include a total of 40 rooftop HVAC units for the proposed residential/ retail building. The HVAC equipment could operate 24 hours per day. Each HVAC unit associated with the retail spaces would generate a sound power level (SWL) that ranges between 76.0 dBA and

79.0 dBA, which would be equivalent to noise levels of 44.4 dBA Leq and 47.4 dBA Leq at a distance of 50 ft. Each HVAC unit associated with residential uses would generate a sound pressure level (SPL) ranging between 60.0 dBA Leq and 63.0 dBA Leq at a distance of 3.3 ft. At a distance of 50 ft, noise levels would range between 36.3 dBA Leq and 39.3 dBA Leq. The composite noise level of all 40 HVAC units would be 56.2 dBA at a distance of 50 ft. The composite HVAC noise calculations are provided in Attachment E.
10/9/23 «P:\HAV2001\Noise\Product\Noise Memo_20231009.docx» 31 The 40 rooftop HVAC units would be shielded by the roofline and parapet, which would provide a minimum noise reduction of 8 dBA. Table Q summarizes the noise levels generated by the rooftop HVAC units at the adjacent land uses. As shown in Table Q, noise levels generated by the rooftop HVAC units would range from 37.6 to 49.1 dBA Leq. These noise levels would not exceed the City’s daytime and nighttime exterior noise standards of 65 dBA and 55 dBA for residential uses, respectively. In addition, these noise levels would not exceed the City’s daytime and nighttime exterior noise standard of 80 dBA and 70 dBA for commercial uses, respectively. Therefore, no noise impacts from on‐site HVAC equipment would occur, and no noise reduction measures are required.

Long‐Term Ground‐Borne Noise and Vibration
The proposed project would not generate vibration levels. In addition, vibration levels generated from project‐related traffic on the adjacent roadway (Bouquet Canyon Road) are unusual for on‐road vehicles because the rubber tires and suspension systems of on‐road vehicles provide vibration isolation. Therefore, no long‐term vibration impacts from long‐term operations of the project would occur, and no vibration reduction measures are required.

STANDARD CONDITIONS AND REGULATORY COMPLIANCE
Short‐Term Construction Noise Impacts
The following measures would further minimize construction noise:
 The construction contractor shall limit construction activities to between the hours of 7:00 a.m. and 7:00 p.m. Monday through Friday and between the hours of 8:00 a.m. and 6:00 p.m. on Saturday. No work shall be performed outside of these hours or on Sundays, New Year’s Day, Independence Day, Thanksgiving, Christmas, Memorial Day, and Labor Day.  During all project site excavation and grading, the project contractors shall equip all construction equipment, fixed or mobile, with properly operating and maintained mufflers consistent with manufacturers’ standards.
 The construction contractor shall locate equipment staging in areas that will create the greatest distance between construction‐related noise sources and most noise‐sensitive receptors nearest the project site during all project construction.
10/9/23 «P:\HAV2001\Noise\Product\Noise Memo_20231009.docx» 32  The construction contractor shall place all stationary construction equipment so that the emitted noise is directed away from the sensitive receptors nearest the project site.

MEMORANDUM
DATE: August 23, 2023
TO: Robert Neman, Harvard 826 Property LLC
FROM: Ronald Brugger, Senior Air Quality Specialist
SUBJECT: Air Quality and Greenhouse Gas Emissions Impact Analysis Memorandum for the proposed Promenade Flats Project in Santa Clarita, California

INTRODUCTION
This air quality and greenhouse gas (GHG) emissions impact analysis for the proposed Promenade Flats Project at 26135 Bouquet Canyon Road in Santa Clarita, California (project) has been prepared using methods and assumptions recommended in the South Coast Air Quality Management District’s (SCAQMD) CEQA Air Quality Handbook (SCAQMD 1993). This analysis includes a description of existing regulatory framework, an assessment of project operational air quality emissions, and an assessment of GHG emissions. Measures to reduce or eliminate significant impacts are identified, where appropriate. All references cited in the memorandum are included in Attachment A.

Project Location
The project site is located along the west side of Bouquet Canyon Road, north of Magic Mountain Parkway and south of Cinema Drive at (Assessor’s Parcel Number 2811‐003‐018), 26135 Bouquet Canyon Road in the community of Valencia. The project site has a Mixed‐Use Corridor (MXC) zoning designation. Figure 1 shows the project location (all figures are in Attachment B).

Project Description
The proposed project would remove a portion of the existing parking lot to accommodate a new four‐story, mixed‐use building on 1.2 acres. The proposed project would include a total of 15,741.50 square feet (sf) of commercial use consisting of a 7,266.10 sf first‐floor retail space, a 3,027.40 sf rooftop yoga studio, and the existing 5,448 sf International House of Pancakes (IHOP) restaurant. In addition to the new commercial uses, the proposed building would include four live/work units and 26 one‐bedroom units on floors two through four. A new 14,359 sf (0.33 acre) parking lot would be constructed on an adjacent vacant parcel to offset the parking that would be removed as part of the project. Construction of the proposed project would start in January 2024 and would be completed in approximately 12 months. Figure 2 shows the site plan. Project traffic is described in the Transportation Memorandum (LSA 2022).

Land Uses in the Project Vicinity
Land uses surrounding the proposed building include the Las Flores Apartments and the Global Prep Academy to the west of the project site. The new parking lot would be just south of the Las Flores 10/9/23 «P:\HAV2001\AQ‐GHG\Products\HAV2001 AQ‐GHG Memo_20231006.docx» 2 Apartments. Otherwise, there are commercial uses to the north, east, and south. Bouquet Canyon Road and the Metrolink rail are located east of the project.

Climate/Meteorology
Air quality in the planning area is affected not only by various emission sources (e.g., mobile and industry) but also by atmospheric conditions (e.g., wind speed, wind direction, temperature, and rainfall). The combination of topography, low mixing height, abundant sunshine, and emissions from the second‐largest urban area in the United States gives the South Coast Air Basin (Basin) some of the worst air pollution problems in the nation.

The Santa Clarita Valley is surrounded by the Santa Susana and San Gabriel mountain ranges on the south, east and west, and the Sierra Pelona Mountains on the north. The Valley lies in a transitional microclimatic zone of the Basin between the “valley marginal” and “high desert” climate types.

Situated far enough from the ocean to escape coastal influences, the Valley’s climate is generally mild with hot summers and sunny, warm winters. Average annual precipitation is about 13 inches, usually received between November and March, although some mountain areas south of the Valley may receive up to 24 inches of precipitation per year.

However, transport of the pollution that is emitted in the southern parts of the Basin and in the San Fernando Valley gets transported by onshore winds up through the Newhall Pass up toward the Santa Clarita Valley results in high levels of ground‐level ozone every summer. Though Santa Clarita sits between two of the largest pollution areas, Los Angeles and Bakersfield, most of the air quality readings for the Santa Clarita Valley range between 58 to 78 percent below the state average.

REGULATORY FRAMEWORK
Air quality and GHG standards and the regulatory framework are discussed below.

Federal Regulations
Pursuant to the federal Clean Air Act (CAA) of 1970, the United States Environmental Protection Agency (EPA) established the National Ambient Air Quality Standards (NAAQS). The NAAQS were established for six major pollutants, termed “criteria” pollutants. Criteria pollutants are defined as those pollutants for which the federal and State governments have established AAQS, or criteria, for outdoor concentrations to protect public health.

The EPA has designated the Southern California Association of Governments (SCAG) as the Metropolitan Planning Organization responsible for ensuring compliance with the requirements of the CAA for the Basin.

The United States has historically had a voluntary approach to reducing GHG emissions; however, on April 2, 2007, the United States Supreme Court ruled that the EPA has the authority to regulate carbon dioxide (CO2) emissions under the CAA. The Supreme Court ruled that GHGs fit within the CAA’s definition of a pollutant and that the EPA did not have a valid rationale for not regulating GHGs. In December 2009, the EPA issued an endangerment finding for GHGs under the CAA. 10/9/23 «P:\HAV2001\AQ‐GHG\Products\HAV2001 AQ‐GHG Memo_20231006.docx» 3 On December 7, 2009, the EPA Administrator signed a final action under the CAA, finding that six GHGs (i.e., CO2, methane [CH4], nitrous oxide [N2O], hydrofluorocarbons [HFCs], perfluorocarbons [PFCs], and sulfur hexafluoride [SF6]) constitute a threat to public health and welfare and that the combined emissions from motor vehicles cause and contribute to global climate change (GCC).

Multistate
The Western Regional Climate Action Initiative
The Western Regional Climate Action Initiative is a partnership among seven states including California and four Canadian provinces to implement a regional, economy‐wide cap‐and‐trade system to reduce global warming pollution. The Western Regional Climate Action Initiative will cap GHG emissions from the region’s electricity, industrial, and transportation sectors with the goal to reduce the heat trapping emissions that cause global warming to 15% below 2005 levels by 2020.

When the Western Regional Climate Action Initiative adopted this goal in 2007, it estimated this would require 2007 levels to be reduced worldwide between 50% and 85% by 2050. California is working closely with the other states and provinces to design a regional GHG reduction program that includes a cap‐and‐trade approach.

The California Air Resources Board (CARB) has implemented a cap‐and‐trade program that is also intended to link California and the other member states and provinces. The cap‐and‐trade regulation, which is a key element of California’s climate plan, took effect in January 2012 and compliance obligation began in January 2013. The cap‐and‐trade program sets a statewide limit on sources responsible for 85% of California’s GHG emissions and establishes a price signal needed to drive long‐term investment in cleaner fuels and more efficient use of energy. As of January 1, 2014, California’s cap‐and‐trade program is linked to Quebec’s pursuant to the Agreement Between the CARB and the Gouvernement du Québec Concerning the Harmonization and Integration of Cap‐and‐ Trade Programs Reducing Greenhouse Gas Emissions, in accordance with the direction in CARB Board Resolution 13‐7 (CARB 2013). As of January 1, 2018, California’s cap‐and‐trade program and Québec’s program linked with Ontario’s cap‐and‐trade program. However, on July 3, 2018, the Ontario government revoked its cap‐and‐trade regulation. With Ontario’s withdrawal from the linked program, California and Québec will work together to ensure that the environmental integrity and stringency of the cap‐and‐trade program/market is sustained (CARB n.d.‐a).

The program is designed to provide covered entities the flexibility to seek out and implement the lowest‐cost options to reduce emissions. The first phase of the cap‐and‐trade regulation included electricity generated in and imported into California, large combustion sources (i.e., generally those emitting more than 25,000 metric tons [MT] of carbon dioxide equivalent [CO2e] per year), and certain industrial sectors. The second phase added providers of transportation fuels and other combustion fuels (e.g., natural gas, propane) to the cap‐and‐trade program. The regulation requires that emissions generated by these facilities and combustion of fuels be reduced over time under a declining cap.

Pacific Coast Action Plan on Climate and Energy
On October 28, 2013, the Governors of California, Oregon, and Washington and the Premier of British Columbia signed a clean energy pact, known as the Pacific Coast Action Plan on Climate and Energy. Although the Pacific Coast Action Plan does not impose legally enforceable obligations and 10/9/23 «P:\HAV2001\AQ‐GHG\Products\HAV2001 AQ‐GHG Memo_20231006.docx» 4 lacks a specific schedule for implementation, the pact sets out a number of goals and aspirational measures. The Pacific Coast Action Plan calls upon each of the parties to undertake a number of measures to address the use of carbon‐based fuels in the transportation sector, including the adoption or maintenance of low‐carbon fuel standards, the development of targets and action plans in order to encourage public and private investment in low‐carbon commercial fleets that use alternative fields, and the expansion of the sale of zero‐emissions vehicles to a goal of 10% of new vehicle purchases by 2016.

California Air Resources Board
In 1967, the State Legislature passed the Mulford‐Carrell Act, which combined two Department of Health bureaus (i.e., the Bureau of Air Sanitation and the Motor Vehicle Pollution Control Board) to establish CARB. Since its formation, CARB has worked with the public, the business sector, and local governments to find solutions to the State’s air pollution problems. California adopted the California Clean Air Act (CCAA) in 1988. CARB administers the California Ambient Air Quality Standards (CAAQS) for the 10 air pollutants designated in the CCAA. These 10 State air pollutants are the 6 criteria pollutants designated by the federal CAA as well as 4 others: visibility‐reducing particulates, hydrogen sulfide (H2S), sulfates, and vinyl chloride.

The California Global Warming Solutions Act of 2006, widely known as Assembly Bill (AB) 32, requires CARB to develop and enforce regulations for the reporting and verification of statewide GHG emissions. CARB was directed to set a statewide GHG emissions limit and set a timeline for adopting a scoping plan for achieving GHG reductions in a technologically and economically feasible manner.

The heart of the bill is the requirement that statewide GHG emissions be reduced to 1990 levels by 2020. The bill requires CARB to adopt rules and regulations in an open public process to achieve the maximum technologically feasible and cost‐effective GHG reductions.

In 2016, the Legislature passed and Governor Jerry Brown signed, Senate Bill (SB) 32 and AB 197.

SB 32 affirms the importance of addressing climate change by codifying into statute the GHG emissions reductions target of at least 40 percent below 1990 levels by 2030 contained in Governor Brown’s April 2015 Executive Order (EO) B‐30‐15. SB 32 builds on AB 32 and keeps California on the path toward achieving the State’s 2050 objective of reducing emissions to 80 percent below 1990 levels, consistent with an Intergovernmental Panel on Climate Change (IPCC) analysis of the emissions trajectory that would stabilize atmospheric GHG concentrations at 450 parts per million (ppm) CO2e and reduce the likelihood of catastrophic impacts from climate change (IPCC 2023). The companion bill to SB 32, AB 197, provides additional direction to CARB related to the adoption of strategies to reduce GHG emissions.

CARB adopted the 2022 Scoping Plan Update on December 15, 2022. The 2022 Scoping Plan Update assesses progress toward the statutory 2030 target, while laying out a path to achieving carbon neutrality no later than 2045. The 2022 Scoping Plan Update focuses on outcomes needed to achieve carbon neutrality by assessing paths for clean technology, energy deployment, natural and working lands, and others and is designed to meet the State’s long‐term climate objectives and support a range of economic, environmental, energy security, environmental justice, and public health priorities. Appendix D of the Scoping Plan includes information about project attributes that 10/9/23 «P:\HAV2001\AQ‐GHG\Products\HAV2001 AQ‐GHG Memo_20231006.docx» 5 would reduce operational GHG emissions and accommodate growth in a manner consistent with State GHG reduction and equity prioritization goals.

Although the 2022 Scoping Plan does not impose any specific mandates or policies that specifically apply to individual development projects such as the proposed project, the Scoping Plan encourages local municipalities to update building codes and establish sustainable development practices for accommodating future growth. Key policies that involve the residential and commercial building sectors that are indirectly applicable to the proposed Project include the implementation of SB 275 (promoting infill development and high‐density housing in high quality transit areas), implementing green building practices (i.e., the California Green Building Standards Code), energy efficiency and water conservation policies, and waste diversion efforts.

Senate Bill 97 and CEQA Guidelines
In August 2007, the Legislature adopted SB 97, requiring the Office of Planning and Research (OPR) to prepare and transmit new California Environmental Quality Act (CEQA) guidelines for the mitigation of GHG emissions or the effects of GHG emissions to the California Natural Resources Agency. OPR submitted its proposed guidelines to the Secretary for Natural Resources on April 13, 2009, and the CEQA Guidelines amendments were adopted on December 30, 2009 and became effective on March 18, 2010.

The CEQA Guidelines amendments do not specify a threshold of significance for GHG emissions or prescribe assessment methodologies or specific mitigation measures. Instead, the amendments encourage lead agencies to consider many factors in performing a CEQA analysis but rely on the lead agencies in making their own significance determinations based upon substantial evidence. The CEQA Guidelines amendments also encourage public agencies to make use of programmatic mitigation plans and programs from which to tier when they perform individual project analyses.

The CEQA Guidelines amendments require a lead agency to make a good‐faith effort based on the extent possible on scientific and factual data to describe, calculate or estimate the amount of GHG emissions resulting from a project. The CEQA Guidelines amendments give discretion to the lead agency whether to (1) use a model or methodology to quantify GHG emissions resulting from a project and which model or methodology to use and/or (2) rely on a qualitative analysis or performance‐based standards. The California Natural Resources Agency is required to periodically update the guidelines to incorporate new information or criteria established by CARB pursuant to AB 32.

California Green Building Standards
The California Green Building Standards Code, which is Part 11 of the California Code of Regulations, is commonly referred to as the CALGreen Code. The first edition of the CALGreen Code was released in 2008 and contained only voluntary standards. The 2022 CALGreen Code was updated in 2022, became effective on January 1, 2023, and applies to non‐residential and residential developments.

The CALGreen Code contains requirements for construction site selection, stormwater control during construction, construction waste reduction, indoor water use reduction, material selection, natural resource conservation, site irrigation conservation, and more. The CALGreen Code provides for design options allowing the designer to determine how best to achieve compliance for a given site or building condition. The CALGreen Code also requires building commissioning, which is a 10/9/23 «P:\HAV2001\AQ‐GHG\Products\HAV2001 AQ‐GHG Memo_20231006.docx» 6 process for the verification that all building systems, such as heating and cooling equipment and lighting systems, function at their maximum efficiency. The proposed project would be subject to the 2022 CALGreen Code that became effective on January 1, 2023. Requirements of the 2022 CALGreen Code that are applicable to the proposed project include the following:

4.106.4 Electric Vehicle (EV) charging. New construction shall comply with Section 4.106.4.1 or 4.106.4.2 to facilitate future installation and use of EV chargers. Electric vehicle supply equipment (EVSE) shall be installed in accordance with the California Electrical Code, Article 625.

4.303.1 Water Conserving Plumbing Fixtures and Fittings. All water fixtures shall comply with the California Code of Regulations, Title 20, (Appliance Efficiency Regulations), Section 1605.1(h)(4) and Section 1605.3(h)(4)(A).

4.304.1 Outdoor Potable Water Use in Landscape Areas. Residential developments shall comply with a local water efficient landscape ordinance or the current California Department of Water Resources’ Model Water Efficient Landscape Ordinance (MWELO), whichever is more stringent.

4.408.1 Construction Waste Management. Recycle and/or salvage for reuse a minimum of 65 percent of the nonhazardous construction and demolition waste in accordance with Section 5.408.1.1, 5.408.1.2, or 5.408.1.3, or meet the City’s construction and demolition waste management ordinance, whichever is more stringent.

4.410.2 Recycling by Occupants. Where 5 or more multifamily units are constructed on a building site, provide readily accessible areas that serve all buildings on the site and are identified for the depositing, storage, and collection of non‐hazardous materials for recycling, including (at a minimum) paper, corrugated cardboard, glass, plastics, organic waste, and metals, or meet the City’s local recycling ordinance, whichever is more restrictive.

Regional Air Quality Planning Framework
SCAG is a council of governments for Imperial, Los Angeles, Orange, Riverside, San Bernardino, and Ventura Counties. SCAG is a regional planning agency and a forum for regional issues relating to transportation, the economy and community development, and the environment. Although SCAG is not an air quality management agency, it is responsible for developing transportation, land use, and energy conservation measures that affect air quality.

On September 3, 2020, the Regional Council of SCAG adopted Connect SoCal, also known as the 2020–2045 Regional Transportation Plan/Sustainable Communities Strategy: A Plan for Mobility, Accessibility, Sustainability, and High Quality of Life (a.k.a., 2020–2045 RTP/SCS). The 2020–2045 RTP/SCS is a long‐range visioning plan that balances future mobility and housing needs with economic, environmental and public health goals. Connect SoCal embodies a collective vision for the region’s future and is developed with input from local governments, county transportation commissions (CTCs), tribal governments, non‐profit organizations, businesses and local stakeholders within the counties of Imperial, Los Angeles, Orange, Riverside, San Bernardino and Ventura. 10/9/23 «P:\HAV2001\AQ‐GHG\Products\HAV2001 AQ‐GHG Memo_20231006.docx» 7 South Coast Air Quality Management District
The SCAQMD is the agency principally responsible for comprehensive air pollution control in the Basin. To that end, the SCAQMD, a regional agency, works directly with SCAG, county transportation commissions and local governments, and cooperates actively with State and federal government agencies. The SCAQMD develops air quality‐related rules and regulations, establishes permitting requirements, inspects emissions sources, and provides regulatory enforcement through such measures as educational programs or fines, when necessary.

Regional Air Quality Management Plan
SCAQMD and SCAG are responsible for formulating and implementing the Air Quality Management Plan (AQMP) for the Basin. The main purpose of an AQMP is to bring the area into compliance with federal and State air quality standards. SCAQMD prepares a new AQMP every 3 years, updating the previous plan and a 20‐year horizon.

The latest plan is the 2022 AQMP (SCAQMD 2022), adopted December 2, 2022. On October 1, 2015, the EPA strengthened the NAAQS for ground‐level ozone, lowering the primary and secondary ozone standard levels to 70 parts per billion (ppb). The Basin is classified as an “extreme” nonattainment area. The 2022 AQMP was developed to address the requirements for meeting this standard. SCAQMD adopts rules and regulations to implement portions of the AQMP. Several of these rules may apply to project construction or operation. For example, SCAQMD Rule 403 requires the implementation of the best‐available fugitive dust control measure during active construction periods capable of generating fugitive dust emissions from on‐site earth‐moving activities, construction/demolition activities, and construction equipment travel on paved and unpaved roads.

Although SCAQMD is responsible for regional air quality planning efforts, it does not have the authority to directly regulate the air quality issues associated with new development projects within the Basin, such as the proposed project. Instead, SCAQMD published the CEQA Air Quality Handbook (SCAQMD 1993) to assist lead agencies, as well as consultants, project proponents, and other interested parties in evaluating potential air quality impacts of projects proposed in the Basin. The CEQA Air Quality Handbook provides standards, methodologies, and procedures for conducting air quality analyses in Environmental Impact Reports and was used extensively in the preparation of this analysis. SCAQMD is currently in the process of replacing the CEQA Air Quality Handbook (1993) with the Air Quality Analysis Guidance Handbook (SCAQMD n.d.).

To assist the CEQA practitioner in conducting an air quality analysis in the interim while the replacement Air Quality Analysis Guidance Handbook is being prepared, supplemental guidance/ information is provided on the SCAQMD website and includes (1) on‐road vehicle emission factors, (2) background carbon monoxide (CO) concentrations, (3) localized significance thresholds (LSTs), (4) mitigation measures and control efficiencies, (5) mobile‐source toxics analysis, (6) off‐road mobile‐ source emission factors, (7) particulate matter less than 2.5 microns in size [PM2.5] significance thresholds and calculation methodology, and (8) updated SCAQMD Air Quality Significance Thresholds. SCAQMD also recommends using approved models to calculate emissions from land use projects, such as the California Emissions Estimator Model (CalEEMod). These recommendations were followed in the preparation of this analysis.

The following SCAQMD rules and regulations would apply to the proposed project:
10/9/23 «P:\HAV2001\AQ‐GHG\Products\HAV2001 AQ‐GHG Memo_20231006.docx» 8  SCAQMD Rule 403 (SCAQMD 2005) requires projects to incorporate fugitive dust control measures.
 SCAQMD Rule 1113 (SCAQMD 2016) limits the volatile organic compound (VOC) content of architectural coatings.

Local Regulations
City of Santa Clarita General Plan
Local jurisdictions, such as the City of Santa Clarita, have the authority and responsibility to reduce air pollution through their police power and decision‐making authority. Specifically, the City is responsible for the assessment and mitigation of air emissions resulting from its land use decisions.

The City is also responsible for implementation of the transportation control measures in the AQMP, such as bus turnouts, energy‐efficient streetlights, and synchronized traffic signals.

The Conservation and Open Space Element of the City of Santa Clarita General Plan has identified goals, objectives, and policies aimed at greenhouse gas reduction at the citywide level (City of Santa Clarita 2011).

City of Santa Clarita Climate Action Plan
The City developed and published its Final Climate Action Plan (CAP) in August 2012. The CAP, part of the General Plan, serves as a component of the general plan document for the City to address GHG emissions. Using the goals, objectives, and policies of the General Plan as a starting point, the CAP identifies mitigation measures that can be quantified and translated into significant reductions in the GHG emissions by the year 2020. Measures identified in the City’s CAP will not only meet but exceed the State’s Global Warming Solutions Act of 2006 (AB 32) GHG emission reduction mandate (City of Santa Clarita 2012).

The CAP defines a local threshold of significance for GHG emissions for project level submittals that trigger review by CEQA. Because goals, objectives, and policies approved under the General Plan are forecast to meet the GHG emission reduction targets mandated by AB 32, development projects that are able to demonstrate consistency with the General Plan and zoning ordinance will by association demonstrate consistency with the CAP. However, because the CAP is only certified through 2020 it is not utilized for CEQA streamlining in this analysis.

THRESHOLDS OF SIGNIFICANCE
Certain air districts (e.g., SCAQMD) have created guidelines and requirements to conduct air quality analyses. SCAQMD’s current guidelines, the CEQA Air Quality Handbook (SCAQMD 1993) with associated updates, were followed in this assessment of air quality and climate impacts for the proposed project.

Based on the State CEQA Guidelines, Appendix G (Public Resources Code Sections 15000–15387), a project would normally be considered to have a significant effect on air quality if the project would violate any CAAQS, contribute substantially to an existing air quality violation, expose sensitive receptors to substantial pollutants concentrations, or conflict with adopted environmental plans and goals of the community in which it is located.
10/9/23 «P:\HAV2001\AQ‐GHG\Products\HAV2001 AQ‐GHG Memo_20231006.docx» 9 Pollutants with Regional Effects
SCAQMD has established daily emissions thresholds for construction and operation of a proposed project in the Basin. The emissions thresholds were established based on the attainment status of the Basin with regard to air quality standards for specific criteria pollutants. Because the concentration standards were set at a level that protects public health with an adequate margin of safety (SCAQMD 2022), these emissions thresholds are regarded as conservative and would overstate an individual project’s contribution to health risks. Table 1 lists the CEQA significance thresholds for construction and operational emissions established for the Basin.

Localized Impacts Analysis
SCAQMD published its Final Localized Significance Threshold Methodology in June 2003 and updated it in July 2008 (SCAQMD 2008), recommending that all air quality analyses include an assessment of both construction and operational impacts on the air quality of nearby sensitive receptors. LSTs represent the maximum emissions from a project site that are not expected to result in an exceedance of the NAAQS or the CAAQS for CO, nitrogen dioxide (NO2), particulate matter less than 10 microns in size (PM10), and PM2.5. LSTs are based on the ambient concentrations of that pollutant within the project’s Source Receptor Area (SRA) and the distance to the nearest sensitive receptor.

For this project, the appropriate SRA is the Santa Clarita Valley area (SRA 13). Sensitive receptors include residences, schools, hospitals, and similar uses that are sensitive to adverse air quality. As described above, the closest sensitive receptors are the Las Flores Apartments, which are approximately 80 feet (ft) from the west boundary of the building construction and approximately 45 ft from the north boundary of the parking lot construction.

If the total acreage disturbed is less than or equal to 5 acres (ac) per day, then the SCAQMD’s screening look‐up tables can be used to determine if a project has the potential to result in a significant impact. The project site is approximately 1.2 ac and the parking lot is 0.43 ac. The emissions from the larger site would be greater than the smaller and the minimum distance the LST 10/9/23 «P:\HAV2001\AQ‐GHG\Products\HAV2001 AQ‐GHG Memo_20231006.docx» 10 methodology is designed to assess is 25 meters (or 80 ft). Therefore, 1.2 ac LSTs at 80 ft distance (derived by interpolation) were used for construction emissions from both sites.

Table 2 lists the emissions thresholds that apply during project construction.

Greenhouse Gas Emissions
State CEQA Guidelines Section 15064(b) provides that the “determination of whether a project may have a significant effect on the environment calls for careful judgment on the part of the public agency involved, based to the extent possible on scientific and factual data”, and further states that an “ironclad definition of significant effect is not always possible because the significance of an activity may vary with the setting.”
Appendix G of the State CEQA Guidelines includes significance thresholds for GHG emissions. A project would normally have a significant effect on the environment if it would do either of the following:
 Generate GHG emissions, either directly or indirectly, that may have a significant impact on the environment; or
 Conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing the emissions of GHGs.

Currently, there is no statewide GHG emissions threshold that has been used to determine the potential GHG emissions impacts of a project. Threshold methodology and thresholds are still being developed and revised by air districts in California.

As described above, the City published its Final CAP in August 2012. The CAP identified measures to support meeting the 2020 GHG emissions goals. However, since the CAP hasn’t been updated to be consistent with State goals detailed in SB 32, EO B‐30‐15, and EO S 3‐05 to reduce GHG emissions by 40 percent below 1990 levels by 2030, the SCAQMD threshold described below was used.

To provide guidance to local lead agencies on determining significance for GHG emissions in their CEQA documents, SCAQMD convened a GHG CEQA Significance Threshold Working Group (Working Group) in 2008. This Working Group proposed a tiered approach for evaluating GHG emissions for development projects where SCAQMD is not the lead agency. The applicable tier for this project is Tier 3, which states that if GHG emissions are less than 3,000 MT CO2e per year, project‐level and cumulative GHG emissions would be less than significant. 10/9/23 «P:\HAV2001\AQ‐GHG\Products\HAV2001 AQ‐GHG Memo_20231006.docx» 11

IMPACTS AND MITIGATION MEASURES
Emissions would include criteria air pollutants and GHG emissions. The sections below describe the proposed project’s consistency with applicable air quality plans, estimated project emissions, and the significance of impacts with respect to SCAQMD thresholds.

Air Quality Impacts
Consistency with Applicable Air Quality Plans
A consistency determination plays an essential role in local‐agency project review by linking local planning and unique individual projects to the air quality plans. A consistency determination fulfills the CEQA goal of fully informing local‐agency decision‐makers of the environmental costs of the project under consideration at a stage early enough to ensure that air quality concerns are addressed. Only new or amended General Plan elements, Specific Plans, and significantly unique projects need to undergo a consistency review due to the air quality plan strategy being based on projections from local General Plans.

The AQMP is based on regional growth projections developed by SCAG. The proposed project is a mixed‐use development that would not house more than 1,000 persons, occupy more than 40 ac of land, or encompass more than 650,000 sf of floor area. Thus, the proposed project would not be defined as a regionally significant project under CEQA; therefore, it does not meet SCAG’s Intergovernmental Review criteria.

The proposed land use is consistent with the General Plan zoning. Thus, the proposed project, as analyzed, would result in air emissions that are consistent with the City’s plans. The City’s General Plan is consistent with the SCAG Regional Comprehensive Plan Guidelines and the SCAQMD AQMP.

Pursuant to the methodology provided in Chapter 12 of the 1993 SCAQMD CEQA Air Quality Handbook, consistency with the Basin 2016 AQMP is affirmed when a project would not increase the frequency or severity of an air quality standards violation or cause a new violation, and is consistent with the growth assumptions in the AQMP. Consistency review is presented as follows:

1. The project would result in short‐term construction and long‐term operational pollutant emissions that are all less than the CEQA significance emissions thresholds established by SCAQMD, as demonstrated above. Therefore, the project would not result in an increase in the frequency or severity of an air quality standard violation or cause a new air quality standard violation.

2. The CEQA Air Quality Handbook (SCAQMD 1993) indicates that consistency with AQMP growth assumptions must be analyzed for new or amended General Plan elements, Specific Plans, and significant projects. Significant projects include airports, electricity‐generating facilities, petroleum and gas refineries, designation of oil‐drilling districts, water ports, solid‐waste disposal sites, and offshore‐drilling facilities; therefore, as a small coffee shop, the proposed project is not defined as significant.

Based on the consistency analysis presented above, the proposed project would be consistent with the regional AQMP.

The Basin is designated as non‐attainment for ozone (O3) and PM2.5 for federal standards and non‐ attainment for O3, PM10, and PM2.5 for State standards. The SCAQMD’s nonattainment status is attributed to the region’s development history. Past, present, and future development projects contribute to the region’s adverse air quality impacts on a cumulative basis. By its very nature, air pollution is largely a cumulative impact. No single project is sufficient in size to, by itself, result in nonattainment of ambient air quality standards. Instead, a project’s individual emissions contribute to existing cumulatively significant adverse air quality impacts. If a project’s contribution to the cumulative impact is considerable, then the project’s impact on air quality would be considered significant.

In developing thresholds of significance for air pollutants, the SCAQMD considered the emission levels for which a project’s individual emissions would be cumulatively considerable. If a project exceeds the identified significance thresholds, its emissions would be cumulatively considerable, resulting in significant adverse air quality impacts to the region’s existing air quality conditions.

Construction Emissions. Construction activities produce combustion emissions from various sources (utility engines, tenant improvements, and motor vehicles transporting the construction crew). Exhaust emissions from construction activities envisioned on site would vary daily as construction activity levels change.

The construction analysis includes estimating the construction equipment that would be used during each construction activity, the hours of use for that construction equipment, the quantities of earth and debris to be moved, and the on‐road vehicle trips (e.g., worker, soil‐hauling, and vendor trips).

The proposed demolition of the existing 10,645 sf parking lot was estimated by assuming the pavement is 145 pounds per sf, resulting in 772 tons of material to haul. The proposed earthwork for the project assumes the site would be balanced (no import or export needed). CalEEMod defaults are assumed for the construction activities, off‐road equipment, and on‐road construction fleet mix and trip lengths. It is expected that construction would start in January 2024 and finish in approximately 16 months. Table 3 lists the tentative project construction schedule.

CalEEMod = California Emissions Estimator Model
The emissions rates shown in Table 5 are from the CalEEMod output tables listed as “Mitigated Construction,” even though the only measures that have been applied to the analysis are the required construction emissions control measures, or standard conditions. They are also the combination of the on‐ and off‐site emissions and the greater of summer and winter emissions. No exceedances of any criteria pollutants are expected. Standard measures are documented in the CalEEMod output in Attachment C.

Fugitive Dust. Fugitive dust emissions are generally associated with land clearing and exposure of soils to the air and wind, as well as cut‐and‐fill grading operations. Dust generated during construction varies substantially on a project‐by‐project basis, depending on the level of activity, the specific operations, and weather conditions at the time of construction. 10/9/23 «P:\HAV2001\AQ‐GHG\Products\HAV2001 AQ‐GHG Memo_20231006.docx» 14 Table 5: Short‐Term Regional Construction Emissions

The construction calculations prepared for this project assumed that dust control measures (watering a minimum of two times daily consistent with SCAQMD Rule 403) would be employed to reduce emissions of fugitive dust during site grading. Furthermore, all construction would need to comply with SCAQMD Rule 403 regarding the emission of fugitive dust. Table 5 lists total construction emissions (i.e., fugitive dust emissions and construction equipment exhausts) that have incorporated the following Rule 403 measures that would be implemented to significantly reduce PM10 emissions from construction:
 Water active sites at least twice daily (locations where grading is to occur shall be thoroughly watered prior to earthmoving).
 Cover all trucks hauling dirt, sand, soil, or other loose materials, or maintain at least 2 ft (0.6 meter) of freeboard (vertical space between the top of the load and the top of the trailer) in accordance with the requirements of California Vehicle Code Section 23114.  Reduce traffic speeds on all unpaved roads to 15 miles per hour (mph) or less.

These Rule 403 measures were incorporated in the CalEEMod analysis.

Architectural Coatings. Architectural coatings contain VOCs that are part of the O3 precursors.

Based on the proposed project, it is estimated that application of the architectural coatings for the proposed peak construction day would result in a peak of 4 pounds per day (lbs/day) of VOCs. Therefore, VOC emissions from architectural‐coating application would not exceed the SCAQMD VOC threshold of 75 lbs/day.

Localized Impacts Analysis. Table 6 shows the portion of the construction emissions that would be produced on the project sites compared to the LSTs. Table 6 shows that the localized construction emissions would not result in a locally significant air quality impact. 10/9/23 «P:\HAV2001\AQ‐GHG\Products\HAV2001 AQ‐GHG Memo_20231006.docx» 15 Table 6: Construction Localized Impacts Analysis

Odors from Construction Activities. Heavy‐duty equipment in the project area during construction would emit odors, primarily from the equipment exhaust. However, the construction‐produced odors would cease to occur after individual construction is completed.

No other sources of objectionable odors have been identified for the proposed project, and no mitigation measures are required.

SCAQMD Rule 402 regarding nuisances states,
“A person shall not discharge from any source whatsoever such quantities of air contaminants or other material which cause injury, detriment, nuisance, or annoyance to any considerable number of persons or to the public, or which endanger the comfort, repose, health or safety of any such persons or the public, or which cause, or have a natural tendency to cause, injury or damage to business or property.”
The proposed uses are not anticipated to emit any objectionable odors. Therefore, objectionable odors posing a health risk to potential on‐site and existing off‐site uses would not occur as a result of the proposed project.

Naturally Occurring Asbestos. The proposed project site is in Los Angeles County, which is among the counties found to have serpentine and ultramafic rock in their soils (California Department of Conservation 2023). However, according to the California Geological Survey, no such rock has been identified in the project vicinity. Therefore, the potential risk for naturally occurring asbestos during project construction is small and less than significant.

Construction Emissions Conclusions. Tables 5 and 6 show that daily regional construction emissions would not exceed the daily thresholds of any criteria pollutant emission thresholds established by SCAQMD; thus, during construction, there would be no air quality impacts.

Operational Emissions
Long‐term air pollutant emission impacts are those associated with mobile sources (e.g., vehicle trips), energy sources (e.g., electricity and natural gas) and area sources (e.g., architectural coatings and the use of landscape maintenance equipment) related to the proposed project. 10/9/23 «P:\HAV2001\AQ‐GHG\Products\HAV2001 AQ‐GHG Memo_20231006.docx» 16 PM10 emissions result from running exhaust, tire and brake wear, and the entrainment of dust into the atmosphere from vehicles traveling on paved roadways. Entrainment of PM10 occurs when vehicle tires pulverize small rocks and pavement and the vehicle wakes generate airborne dust. The contribution of tire and brake wear is small compared to the other PM emission processes.

Gasoline‐powered engines have small rates of particulate matter emissions compared with diesel‐ powered vehicles. Project traffic is described in the Transportation Memorandum (LSA 2022).

Energy source emissions result from activities in buildings for which electricity and natural gas are used. The quantity of emissions is the product of usage intensity (i.e., the amount of electricity or natural gas) and the emission factor of the fuel source. Major sources of energy demand include building mechanical systems, such as heating and air conditioning, lighting, and plug‐in electronics, such as refrigerators or computers. Greater building or appliance efficiency reduces the amount of energy for a given activity and thus lowers the resultant emissions. The emission factor is determined by the fuel source, with cleaner energy sources, like renewable energy, producing fewer emissions than conventional sources.

Typically, area source emissions consist of direct sources of air emissions located at the project site, including architectural coatings and the use of landscape maintenance equipment. Area source emissions associated with the project would include emissions from the use of landscaping equipment and the use of consumer products.

Emission estimates for operation of the project were calculated using CalEEMod and are shown in Table 7, below. The primary emissions associated with the project are regional in nature, meaning that air pollutants are rapidly dispersed on release. The peak daily emissions associated with project operations are identified in Table 7 for reactive organic gas (ROG), nitrogen oxides (NOx), CO, sulfur oxides (SOx), PM10, and PM2.5.

The results shown in Table 7 indicate the project would not exceed the significance criteria for annual ROG, NOx, CO, SOx, PM10, and PM2.5 emissions; therefore, operation of the proposed project would not result in a cumulatively considerable net increase of any criteria pollutant for which the project region is in nonattainment under an applicable federal or State AAQS. The CalEEMod emission calculations sheets are included in Attachment C. 10/9/23 «P:\HAV2001\AQ‐GHG\Products\HAV2001 AQ‐GHG Memo_20231006.docx» 17 Objectionable Odors. The SCAQMD addresses odor criteria within the CEQA Handbook. The district has not established a rule or standard regarding odor emissions, rather, the district has a nuisance rule: “Any project with the potential to frequently expose members of the public to objectionable odors should be deemed to have a significant impact.”
The proposed project would not include any activities or operations that would generate objectionable odors. Therefore, the proposed project would not result in other emissions (such as those leading to odors) adversely affecting a substantial number of people.

Greenhouse Gas Impacts
Generate Greenhouse Gas Emissions
This section discusses the project’s impacts related to the release of GHG emissions for the construction and operational phases of the project.

Construction Activities. Construction activities associated with maximum buildout would produce combustion emissions from various sources. During construction, GHGs would be emitted through the operation of construction equipment and from worker and builder supply vendor vehicles, each of which typically use fossil‐based fuels to operate. The combustion of fossil‐based fuels creates GHGs such as CO2, CH4, and N2O. Furthermore, CH4 is emitted during the fueling of heavy equipment. Exhaust emissions from on‐site construction activities would vary daily as construction activity levels change.

The SCAQMD does not have an adopted threshold of significance for construction‐related GHG emissions. Based on SCAQMD guidance, construction emissions were amortized over 30 years (a typical project lifetime) to be added to the total project operational emissions. Using CalEEMod, it is estimated that construction activities would generate approximately 278 metric tons of CO2e. Thus, the amortized annual construction emissions would be approximately 9 MT of CO2e per year.

Operational GHG Emissions. Long‐term GHG emissions are typically generated from mobile sources (e.g., cars, trucks and buses), area sources (e.g., maintenance activities and landscaping), indirect emissions from sources associated with energy consumption, waste sources (land filling and waste disposal), and water sources (water supply and conveyance, treatment, and distribution). Mobile‐ source GHG emissions would include project‐generated vehicle and truck trips to and from the project. Area‐source emissions would be associated with activities such as landscaping and maintenance on the project site. Energy source emissions would be generated at off‐site utility providers as a result of increased electricity demand generated by the project. Waste source emissions generated by the proposed project include energy generated by land filling and other methods of disposal related to transporting and managing project generated waste. In addition, water source emissions associated with the proposed project are generated by water supply and conveyance, water treatment, water distribution, and wastewater treatment.

As described above, this analysis evaluates potential operational emissions associated with the proposed project. Operational GHG emissions were estimated using CalEEMod and the results are presented in Table 8.

As shown in Table 8, the project would generate 670 metric tons of CO2e per year. This is less than SCAQMD’s Tier 3 threshold of 3,000 MT CO2e/yr.

Consistency with Greenhouse Gas Reduction Plans
The following discussion evaluates the proposed project according to the goals of the 2022 Scoping Plan, EO B‐30‐15, SB 32, and AB 197.

EO B‐30‐15 added the immediate target of reducing GHG emissions to 40 percent below 1990 levels by 2030. CARB released a second update to the Scoping Plan, the 2017 Scoping Plan, to reflect the 2030 target set by EO B‐30‐15 and codified by SB 32. SB 32 affirms the importance of addressing climate change by codifying into statute the GHG emissions reductions target of at least 40 percent below 1990 levels by 2030 contained in EO B‐30‐15. SB 32 builds on AB 32 and keeps us on the path toward achieving the State’s 2050 objective of reducing emissions to 80 percent below 1990 levels.

The companion bill to SB 32, AB 197, provides additional direction to the CARB related to the adoption of strategies to reduce GHG emissions. Additional direction in AB 197 intended to provide easier public access to air emissions data that are collected by CARB was posted in December 2016.

In addition, the 2022 Scoping Plan assesses progress toward the statutory 2030 target, while laying out a path to achieving carbon neutrality no later than 2045. The 2022 Scoping Plan focuses on outcomes needed to achieve carbon neutrality by assessing paths for clean technology, energy deployment, natural and working lands, and others, and is designed to meet the State’s long‐term climate objectives and support a range of economic, environmental, energy security, environmental justice, and public health priorities.

The 2022 Scoping Plan focuses on building clean energy production and distribution infrastructure for a carbon‐neutral future, including transitioning existing energy production and transmission infrastructure to produce zero‐carbon electricity and hydrogen, and utilizing biogas resulting from wildfire management or landfill and dairy operations, among other substitutes. The 2022 Scoping Plan states that in almost all sectors, electrification will play an important role. The 2022 Scoping 10/9/23 «P:\HAV2001\AQ‐GHG\Products\HAV2001 AQ‐GHG Memo_20231006.docx» 19 Plan evaluates clean energy and technology options and the transition away from fossil fuels, including adding four times the solar and wind capacity by 2045 and about 1,700 times the amount of current hydrogen supply. As discussed in the 2022 Scoping Plan, EO N‐79‐20 requires that all new passenger vehicles sold in California will be zero‐emission by 2035, and all other fleets will have transitioned to zero‐emission as fully possible by 2045, which will reduce the percentage of fossil fuel combustion vehicles.

Energy efficient measures are intended to maximize energy efficiency building and appliance standards, pursue additional efficiency efforts including new technologies and new policy and implementation mechanisms, and pursue comparable investment in energy efficiency from all retail providers of electricity in California. In addition, these measures are designed to expand the use of green building practices to reduce the carbon footprint of California’s new and existing inventory of buildings. As discussed above, the proposed project would comply with the CALGreen Code, regarding energy conservation and green building standards. Therefore, the proposed project would comply with applicable energy measures.

Water conservation and efficiency measures are intended to continue efficiency programs and use cleaner energy sources to move and treat water. Increasing the efficiency of water transport and reducing water use would reduce GHG emissions. As noted above, the project would comply with the CALGreen Code, which includes a variety of different measures, including reduction of wastewater and water use. In addition, the proposed project would be required to comply with the California Model Water Efficient Landscape Ordinance. Therefore, the proposed project would not conflict with any of the water conservation and efficiency measures.

The goal of transportation and motor vehicle measures is to develop regional GHG emissions reduction targets for passenger vehicles. Specific regional emission targets for transportation emissions would not directly apply to the proposed project. The second phase of Pavley standards will reduce GHG emissions from new cars by 34 percent from 2016 levels by 2025, resulting in a 3 percent decrease in average vehicle emissions for all vehicles by 2020. Vehicles traveling to the project site would comply with the Pavley II (LEV III) Advanced Clean Cars Program (CARB n.d.‐b).

Therefore, the proposed project would not conflict with the identified transportation and motor vehicle measures.

The CARB’s 2022 Scoping Plan provides Table 3 “Key Residential and Mixed‐Use Project Attributes that Reduce GHGs” in Appendix D. The table is provided by CARB for use in determining whether a proposed residential or mixed‐use residential development would align with the State’s climate goals, absent a locally or regionally adopted CEQA‐qualified CAP. Table 9 shows the project’s consistency with these attributes.

As described in CARB’s 2022 Scoping Plan, residential and mixed‐use development projects that incorporate all of the applicable key project attributes are aligned with the State’s priority GHG reduction strategies for local climate action and with the State’s climate and housing goals. As shown in Table 9, the project would be considered to be consistent with the Scoping Plan. 10/9/23 «P:\HAV2001\AQ‐GHG\Products\HAV2001 AQ‐GHG Memo_20231006.docx» 20 Table 9: Key Residential and Mixed‐Use Project Attributes that Reduce GHGs Priority Areas Key Project Attribute Project Consistency Transportation

Per CARB guidance, as included in Appendix D of the CARB 2022 Scoping Plan, since the proposed project includes the applicable Local Actions included in Table 9 it would therefore also be considered consistent with the goals of the State and the 2022 Scoping Plan. As such, the proposed project is considered to be consistent with other plans, policies, or regulations adopted for the purposes of reducing GHGs. Furthermore, as the proposed project would meet all requirements of 10/9/23 «P:\HAV2001\AQ‐GHG\Products\HAV2001 AQ‐GHG Memo_20231006.docx» 21 Title 24, CalGreen, and the City’s municipal code, and would incorporate the emission reduction measures included in the City’s CAP, the proposed project would not conflict with the goals of the City’s General Plan or CAP.

In addition, the 2020–2045 RTP/SCS was determined by CARB to achieve CARB’s 2035 GHG reduction targets; therefore, consistency with the RTP/SCS would demonstrate consistency with the 2022 Scoping Plan. As further discussed in the Transportation Memorandum prepared for the proposed project (LSA 2022), the proposed project meets the City’s vehicle miles traveled screening criteria and would have a less than significant impact on the transportation system based on the significance thresholds in Appendix G of the State CEQA Guidelines. Furthermore, the proposed project includes infrastructure to support electrification, and introduces a mix of land uses in an urban area, with residential housing located near workspaces and retail shopping. Therefore, the proposed project would not conflict with the goals of the RTP/SCS.

The low level of project GHG emissions shown in Table 8 combined with the attributes shown in Table 9 indicate that the project would be compliant with all City, regional, and State GHG emissions reduction plans. Therefore, the proposed project’s GHG emissions would not result in a significant impact.

STANDARD CONDITIONS
Construction
The project is required to comply with regional rules that assist in reducing short‐term air pollutant emissions. SCAQMD Rule 403 requires that fugitive dust be controlled with the best‐available control measures so that the presence of such dust does not remain visible in the atmosphere beyond the property line of the emission source (SCAQMD 2005). In addition, SCAQMD Rule 403 requires implementation of dust suppression techniques to prevent fugitive dust from creating a nuisance off site. Applicable dust suppression techniques from Rule 403 are summarized below.

Implementation of these dust suppression techniques can reduce the fugitive dust generation (and thus the PM10 component). Compliance with these rules would reduce impacts on nearby sensitive receptors (SCAQMD 2005). As shown in Table 5, implementation of Rule 403 measures results in dust emissions below SCAQMD thresholds.

The applicable Rule 403 measures are as follows:
 Apply nontoxic chemical soil stabilizers according to manufacturers’ specifications to all inactive construction areas (previously graded areas inactive for 10 days or more).  Water active sites at least twice daily (locations where grading is to occur shall be thoroughly watered prior to earthmoving).
 Cover all trucks hauling dirt, sand, soil, or other loose materials, or maintain at least 2 feet (0.6 meter) of freeboard (vertical space between the top of the load and the top of the trailer) in accordance with the requirements of California Vehicle Code Section 23114.  Pave construction access roads at least 100 feet (30 meters) onto the site from the main road. 10/9/23 «P:\HAV2001\AQ‐GHG\Products\HAV2001 AQ‐GHG Memo_20231006.docx» 22  Reduce traffic speeds on all unpaved roads to 15 mph or less.

The applicable California Department of Resources Recycling and Recovery (CalRecycle) Sustainable (Green) Building Program Measures are:
 Recycle/reuse at least 50 percent of the construction material (including, but not limited to, soil, mulch, vegetation, concrete, lumber, metal, and cardboard) (CalRecycle 2019a).  Use “green building materials” such as those materials that are rapidly renewable or resource‐ efficient, and recycled and manufactured in an environmentally friendly way, for at least 10 percent of the project, as specified on the CalRecycle website (CalRecycle 2019b).

Operations
The proposed project is required to comply with the CALGreen Code and Title 24 of the California Code of Regulations established by the California Energy Commission regarding energy conservation and green building standards.

CONCLUSION
Based on the analysis presented above, the construction and operational emissions associated with the proposed project would not exceed SCAQMD established significance thresholds. The proposed project is not expected to produce significant emissions that would affect nearby sensitive receptors. The proposed project would also not result in objectionable odors affecting a substantial number of people. GHG emissions released during operation of the project are estimated to be lower than significance thresholds and would not be cumulatively considerable. Additionally, the project would not conflict with the goals and objectives of State or regional plan, policy or regulation of an agency adopted for the purpose of reducing GHG emissions.
