Would the project result in substantial adverse
physical impacts associated with the provision of
new or physically altered governmental facilities,
need for new or physically altered governmental
facilities, the construction of which could cause
significant environmental impacts, in order to
maintain acceptable service ratios, response times,
or other performance objectives for any of the
public services:
1) Fire Protection?
2) Police Protection?
3) Schools?
4) Parks?
5) Other Public Facilities?
Impact PS-1: The project would not result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times, or other performance objectives for fire protection services. (Less than Significant Impact) The development of the project would incrementally increase the local population and associated demand on fire protection services. The incremental increase in demand, however, would not, by itself, require new facilities or expansion of existing facilities to provide adequate fire protection services. The project would comply with General Plan Policies OSCCF 6.1, 6.3, and 6.4 which require that community service demands are met, response times for police and fire protection are comparable to similar jurisdictions within Santa Clara County, and that the City continue to work with nearby jurisdictions to provide sufficient emergency services. In addition, the project would be constructed in compliance with the current iterations of the CBC and the CFC to ensure the building is fire safe. The project would be reviewed by the Santa Clara County Fire District to ensure applicable Fire Code standards to reduce potential fire hazards are included in the project design when construction permits are issued, including sprinklers and smoke detectors. For these reasons, the project would not significantly impact fire protection services. (Less than Significant Impact) Impact PS-2: The project would not result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times, or other performance objectives for police protection services. (Less than Significant Impact) 257

330 Distel Circle Residential Project 129 Initial Study City of Los Altos July 2022
The project site is currently served by the Los Altos Police Department. Similar to fire protection services, the proposed project would incrementally increase the demand for police protection services at the project site. The incremental increase in demand for police protection services would not require new or expanded police protection facilities in order to maintain acceptable emergency service. As discussed in Impact PS-1, the project would comply with General Plan Policies OSCCF

6.1, 6.3, and 6.4, which would ensure adequate police protection services.

The project would be constructed in conformance with current codes and the project design would be reviewed by the Los Altos Police Department to ensure that it incorporates appropriate safety features to minimize criminal activity. For these reasons, the project would not significantly impact police protection services. (Less than Significant Impact) Impact PS-3: The project would not result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times, or other performance objectives for schools. (Less than Significant Impact)
The project would develop 90 multi-family residential units. Based on the student generation rate of

0.09 for elementary schools and junior high schools from the Los Altos School District, the project would generate about nine new elementary and middle school students .87 Based on the student generation rate of 0.312 students per unit for the Mountain View Los Altos High School District, the project would generate about 29 new high school students.88 As stated above in Section 4.15.1.2 Existing Conditions, Almond Elementary School is over capacity by 34 students and Egan Junior High School has an existing capacity for an additional 57 students.

Both Almond Elementary School and Egan Junior High School would be able to accommodate the existing student enrollment and the project-generated students with existing facilities.89 As stated above, the project would generate 29 new high school students. Los Altos High School is currently utilizing portable classrooms to meet their enrollment capacity and would continue to do so regardless of the project. New construction funded by Measure E bond program would build permanent classrooms to accommodate additional students.90 Los Altos High School has adequate capacity to meet the project’s demand.

As described above, the project itself would not trigger the need to construct or expand school facilities. The project is required to pay school impact fees in accordance with California Government Code Section 65996 to mitigate its impact to local school facilities to a less than significant level.

Impact PS-4: The project would not result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times, or other performance objectives for parks. (Less than Significant Impact)
The new residents from the project would incrementally increase the use of existing recreational facilities in the project area. The proposed project would include approximately 12,750 square feet of on-site outdoor amenity space that would be partially offset the project’s demand on park facilities.

Per a MOU by the City of Los Altos and the County of Santa Clara, the project would receive a 100 percent discount on park in lieu fees. The project’s MOU by the City and County would allow the project’s exemption from pay impact fees for applicable park improvements, including park in lieu fees, and therefore would not result in a significant impact on parks. (Less than Significant Impact) Impact PS-5: The project would not result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times, or other performance objectives for other public facilities. (Less than Significant Impact) New residents of the project would incrementally increase the use of nearby libraries and community centers, including the Los Altos Library, Grant Park Community Center, and Hillview Community Center. This incremental increase, however, would not necessitate the construction of new facilities or the expansion of existing facilities. For these reasons, the proposed project would not result in significant impacts to libraries, community centers, or other public facilities. (Less than Significant Impact)

4.16.1 Environmental Setting

4.16.1.1 Regulatory Framework
State
Government Code Section 66477
The Quimby Act (included within Government Code Section 66477) requires local governments to set aside parkland and open space for recreational purposes. It provides provisions for the dedication of parkland and/or payment of fees in lieu of parkland dedication to help mitigate the impacts from new residential developments. The Quimby Act authorizes local governments to establish ordinances requiring developers of new residential subdivisions to dedicate parks, pay a fee in lieu of parkland dedication, or perform a combination of the two.

Local
Los Altos General Plan
The following policies in the City’s General Plan have been adopted for the purposes of avoiding or reducing recreation impacts and are applicable to the project:

Policy Description
OSCCF 1.4 Require park dedication, public open space, or require fees in lieu thereof, for all new subdivisions and multi-family residential development in Los Altos.

OSCCF 4.1 Provide adequate level of maintenance for City parks, open space, and public property to ensure safety, aesthetics, and recreational enjoyment for Los Altos residents.

Los Altos Municipal Code
The City of Los Altos has established a Parkland Dedication Ordinance (Chapter 13.24.010 of the Municipal Code) requiring residential subdivisions to dedicate land for park or recreational purposes, or pay a fee in-lieu thereof, as a condition of approval for the final subdivision or parcel map. The intent of the ordinance is to allow development to occur within the City in a manner that meets the City’s parks and recreation goals.

Los Altos Parks Plan
The Los Altos Parks Plan, adopted in May of 2012, is intended to create a clear set of goals, policies, and objectives that will provide direction to the City Council and City staff for the development, improvement, and enhancement of the City’s park system for the next twenty to thirty years. The Parks Plan was designed to parallel the General Plan’s Open Space, Conservation, and Facilities Element by providing specific direction and recommendations related to parks in Los Altos. 260

Impact REC-1: The project would not increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated. (Less than Significant Impact)
As discussed under Impact PS-4 in Section 4.15 Public Services, the project would result in new residents on the project site that would incrementally increase demand on park and other recreational facilities. The project’s on-site outdoor amenity space, including interior courtyard and and compliance with the City’s Park Dedication Ordinance (Chapter 13.24.010 of the Municipal Code) would reduce its impact on parks and recreational facilities to a less than significant level. (Less than Significant Impact)
Impact REC-2: The project does not include recreational facilities or require the construction or expansion of recreational facilities which might have an adverse physical effect on the environment. (Less than Significant Impact) The proposed project would include approximately 12,750 square feet of outdoor amenity space onsite that could include landscaping, lounge areas, a children’s play space, vegetable gardens, and outdoor game areas. The physical impacts of these outdoor amenity spaces are evaluated as part of the project in this Initial Study. As discussed throughout this Initial Study, no significant impacts 261

4.17 TRANSPORTATION
The following is based, in part, on a Transportation Analysis (TA) prepared by Hexagon Transportation Consultants, Inc. dated July 19, 2022. This report is attached as Appendix F to this Initial Study.

4.17.1 Environmental Setting

4.17.1.1 Regulatory Framework
State
Regional Transportation Plan
MTC is the transportation planning, coordinating, and financing agency for the nine-county San Francisco Bay Area, including Santa Clara County. MTC is charged with regularly updating the Regional Transportation Plan, a comprehensive blueprint for the development of mass transit, highway, airport, seaport, railroad, bicycle, and pedestrian facilities in the region. MTC and ABAG adopted Plan Bay Area 2040 in July 2017, which includes a Regional Transportation Plan to guide regional transportation investment for revenues from federal, state, regional and local sources through 2040.

Senate Bill 743
SB 743 establishes criteria for determining the significance of transportation impacts using a vehicle miles traveled (VMT) metric intended to promote the reduction of GHG emissions, the development of multimodal transportation networks, and a diversity of land uses. Specifically, SB 743 requires analysis of VMT in determining the significance of transportation impacts. Local jurisdictions were required by Governor’s Office of Planning and Research (OPR) to implement a VMT policy by July 1, 2020.

SB 743 did not authorize OPR to set specific VMT impact thresholds, but it did direct OPR to develop guidelines for jurisdictions to utilize. CEQA Guidelines Section 15064.3(b)(1) describes factors that might indicate whether a development project’s VMT may be significant. Notably, projects located within 0.50 mile of transit should be considered to have a less than significant transportation impact based on OPR guidance.

Regional and Local
Congestion Management Program
VTA oversees the Congestion Management Program (CMP), which is aimed at reducing regional traffic congestion. The relevant state legislation requires that urbanized counties in California prepare a CMP in order to obtain each county’s share of gas tax revenues. State legislation requires that each CMP define traffic LOS standards, transit service standards, a trip reduction and transportation demand management plan, a land use impact analysis program, and a capital improvement element.

VTA has review responsibility for proposed development projects that are expected to affect CMPdesignated intersections. 263
Agenda Item # 10.
330 Distel Circle Residential Project 135 Initial Study City of Los Altos July 2022
Los Altos General Plan
The following policies in the City’s General Plan have been adopted for the purpose of reducing or avoiding impacts related to transportation and traffic and are applicable to the proposed project.

Policy Description
CE 2.4 Require development projects to mitigate their respective traffic and parking impacts by implementing practical and feasible street improvements CE 2.6 Implement and require developers to implement street improvements that accommodate and encourage the use of non-automobile travel modes including walking, bicycling, and transit.

CE 2.17 Maintain adequate emergency access for all land uses.

CE 2.20 Enhance driving safety in the community.

Los Altos Municipal Code
Title 14 of the City’s Municipal Code consists of the City’s zoning ordinance, which contains the development standards and land use regulations that guide development within Los Altos. Chapter

14.74 of the zoning ordinance describes the off-street parking and loading requirements for each zoning district in the City. These standards include the number of off-street parking spaces required, the number of loading spaces required, the required parking space dimensions, and the required driveway dimensions.

Los Altos Bicycle Transportation Plan
The City’s Bicycle Transportation Plan was adopted in 2012 with the stated goals of increasing the amount of bicycling in the City, improving access to bicycle infrastructure for students, improving commute routes and end-of-trip accommodations, and establishing Los Altos as a biking destination.

The Bicycle Transportation Plan provides a detailed analysis of existing infrastructure conditions, evaluates the needs of the community, provides potential improvements to be implemented, and outlines funding possibilities.

Los Altos Pedestrian Master Plan
The City’s Pedestrian Master Plan was adopted in 2015 to evaluate the existing pedestrian infrastructure in the City and recommend strategies and actions to improve pedestrian facilities. The Pedestrian Master Plan provides an analysis of existing infrastructure and safety conditions, evaluates the needs of the community, provides potential policy and project recommendations, outlines cost estimates and funding possibilities, and provides a strategy for evaluating and prioritizing the potential improvements in the Master Plan.

Neighborhood Traffic Management
In 1999, the City of Los Altos established a comprehensive neighborhood traffic management program (NTMP), which has been periodically updated since then. The most recently updated NTMP 264
Agenda Item # 10.
330 Distel Circle Residential Project 136 Initial Study City of Los Altos July 2022
from 2005 specifies a process for implementing traffic calming measures designed to reduce or manage volumes and travel speeds on local streets.

Los Altos Complete Streets Master Plan
The Complete Streets Master Plan is intended to build from the Bicycle and Pedestrian Master Plans that were previously adopted by the City. The Master Plan provides recommendations and strategies for developing a comprehensive bicycle and pedestrian network that facilitates easy and safe circulation throughout the City. The Master Plan outlines the existing conditions in the City, recommends improvements for the existing infrastructure, provides the Safe Routes to School Plan, and describes a strategy for evaluating and prioritizing suggested improvements.

Los Altos Draft VMT Policy
SB 743 requires local jurisdictions to implement a VMT policy that can utilize analysis of VMT for proposed projects to determine the significance of transportation impacts. The City does not currently have an adopted VMT policy. The City has a Draft VMT Policy that establishes screening criteria to identify projects (including 100 percent affordable) which are presumed to result in a less than significant VMT impact and are not required to prepare a VMT analysis. In lieu of an adopted policy, the City has developed an Interim VMT Policy to comply with state requirements. The Interim VMT Policy establishes procedures to evaluate projects based on their description, characteristics, and location. If a project is 15 percent below the regional average, a project is considered to not have a significant environmental impact.

4.17.1.2 Existing Conditions
Roadway Network
Regional and local roadways providing access to the project site are described below. Additional detail about the existing roadway network is provided in Appendix F. • SR 82, also known as El Camino Real, is a north-south arterial that extends from Daly City in the north to San Jose in the South. Within the Los Altos city limits, El Camino Real is primarily an east-west roadway. El Camino Real provides access to the project site via Distel Circle.
• San Antonio Road is a north-south arterial road that extends northward from Foothill Expressway to US 101. In the vicinity of the project site, it is four lanes wide and has landscaped medians with left-turn pockets at intersections. • Distel Drive is a north-south local street that extends southward from El Camino Real and ends in a cul-de-sac south of Marich Way. In the vicinity of the project site, it is two lanes wide and parking is allowed on both sides of the street. • Rengstorff Avenue is a north-south arterial that extends northward from El Camino Real to Charleston Road. In the vicinity of the project site, it is four lanes wide, has a left turning lanes at intersections, and a landscaped median.

Would the project:
1) Conflict with a program, plan, ordinance, or
policy addressing the circulation system,
including transit, roadways, bicycle lanes, and
pedestrian facilities?
2) Conflict or be inconsistent with CEQA
Guidelines Section 15064.3, subdivision (b)?
3) Substantially increase hazards due to a
geometric design feature (e.g., sharp curves or
dangerous intersections) or incompatible uses
(e.g., farm equipment)?
4) Result in inadequate emergency access?
Impact TRN-1: The project would not conflict with a program, plan, ordinance, or policy addressing the circulation system, including transit, roadways, bicycle lanes, and pedestrian facilities. (Less than Significant Impact) Roadway System
While a project’s effect on automobile delay is no longer considered an impact under CEQA, local jurisdictions have roadway LOS standards. As discussed in Section 4.17.3 Non-CEQA Effects and in more detail in Appendix F, the results of the LOS analysis show that, under near-term and cumulative conditions, several signalized intersections would have a substandard LOS with or without the project being constructed. Although these intersections would have a substandard LOS in the future, the increase in average critical delay would not be greater than four seconds. (Less than Significant Impact)
Bicycle Facilities
As discussed in Section 4.17.1.2, Class I, II, III, and IV bicycle facilities are located in the vicinity of the project site. These bicycle facilities would be unchanged by implementation of the project.

Therefore, the project would not conflict with a program, plan, ordinance, or policy addressing the bicycle circulation system. (Less than Significant Impact) Pedestrian Facilities
As discussed in Section 4.17.1.2, pedestrian facilities in immediate site vicinity include continuous sidewalks on both sides of most of the streets, crosswalks with pedestrian signals at signalized intersections, and a hybrid beacon signal at the intersection of El Camino Real and Distel Circle. As discussed in Section 3.1.2 Site Access and Parking, the project proposes to widen the sidewalk in front of the site from five feet wide to 14 feet wide and replace the existing gutters and curbs, install new landscaping and streetlighting, and construct a plaza for pedestrian use on the southeast corner 271

of the site. For these reasons, the project would not conflict with a program, plan, ordinance, or policy addressing the pedestrian circulation system. (Less than Significant Impact) would ensure
Transit Facilities
As discussed in Section 4.17.1.2 and shown on Figure 4.17-2, the project site is well served by transit services that operate in the nearby vicinity. The City of Mountain View is in the process of implementing the El Camino Real Streetscape Plan which includes a new “Bus Bulb” at the bus stop located at the intersection of Distel Circle and El Camino Real. This improvement would widen the sidewalk at the bus stop location, allowing for additional space for pedestrians. The proposed project would not interfere with the implementation of this planned improvement. The project would result in a slight increase in demand for transit services; however, this increase would be accommodated by existing transit facilities. Therefore, the project would not conflict with a program, plan, ordinance, or policy addressing the transit circulation system. (Less than Significant Impact) Impact TRN-2: The project would not conflict or be inconsistent with CEQA Guidelines Section 15064.3, subdivision (b). (Less than Significant Impact) This question pertains specifically to VMT as the means of analyzing transportation impacts of a project. As described in Section 4.17.1.1 Regulatory Framework, the City does not currently have an adopted VMT policy. The City’s Draft VMT Policy establishes several screening criteria for projects that are expected to result in a less than significant transportation impact under CEQA. Per the City’s Draft VMT Policy, projects with 100 percent affordable housing (such as the proposed project) are presumed to have a less than significant impact and are not required to prepare a VMT analysis.

Although the Draft VMT Policy is not in effect, the project would screen out of the significance thresholds of the draft policy.

Since the City’s Draft VMT Policy has not been adopted, the project is subject to the City’s Interim VMT Policy which sets a threshold of significance for residential VMT per capita at 15 percent below the regional average of 13.95 VMT per capita (or 11.86). Per the Santa Clara County VMT evaluation tool, the project site is located within an area with a residential VMT per capita of 9.51 without the project, which is below the threshold set forth in the City’s Interim VMT Policy.91 Therefore, the project would also be screened out from further analysis using the Interim VMT Policy threshold.

In addition, pursuant to CEQA Guidelines Section 15064.3, subdivision (b), land use projects within one-half mile of an existing major transit stop or a stop along a high-quality transit corridor are designated at TPAs and presumed to result in a less than significant transportation impact.92 As shown in Figure 4.17-2, the project site is within one-half mile of a major transit stop along El 91 Santa Clara Valley Transportation Authority.

Camino Real.93 For this reason, and given the project would screen out of both the City’sDraft VMT Policy and Interim VMT policy, the project is presumed to have a less than significant transportation impact regarding VMT, consistent with CEQA Guidelines Section 15064.3, subdivision (b). (Less than Significant Impact)
Impact TRN-3: The project would not 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) Access to the project site is currently provided via Distel Circle by two separate two-way driveways which lead to the surface parking area in front of the existing office building. The proposed project would remove the southern driveway and replace the northern driveway with a new 23-foot wide, two-way driveway that would lead to the parking garage of the proposed structure. The dimensions of the driveway would exceed the minimum width requirement of 18 feet established in Chapter

14.74 of the Los Altos Municipal Code. In order to ensure adequate sight distance for vehicles entering and exiting the driveway, it is recommended that on-street parking be prohibited 40 feet south and 35 feet north of the driveway entrance along the western side of Distel Circle to increase the level of visibility motorists would have while approaching the driveway.

As shown on Figure 2.4-3, the project site is surrounded by a mix of land uses, including office, commercial, and residential. The proposed residential use is not a new land use in the area. The project, therefore, does not propose a use that is incompatible with the existing mix of uses in the project area or propose a use that would bring unusual equipment on the roadways (e.g., farm equipment). For this reason, the project would not result in a significant impact due to incompatible uses. (Less than Significant Impact)
Impact TRN-4: The project would not result in inadequate emergency access. (Less than Significant Impact)
Emergency vehicles access to the project site would be provided via the new two-way driveway. The proposed development would be reviewed for consistency with applicable California Building Code and Fire Code requirements for access and safety. As such, the proposed project would have a less than significant emergency access impact. (Less than Significant Impact)

4.17.3 Non-CEQA Effects
Level of Service
As noted above in Section 4.17.1.2, a project’s effects on LOS shall no longer be considered an impact on the environment. This discussion on LOS is included because the City has adopted LOS goals, outside of the CEQA process. The LOS Standards for the studied intersections range from D to E, and an operation deficiency would be attributed to the project if the additional trips caused by project implementation would result in an increase in average delay at signalized study intersections by more than four seconds. In the event a project causes an LOS deficiency, the City has discretion 93 Metropolitan Transportation Commission. Transit Priority Areas (2021). Accessed June 28, 2022. https://opendata.mtc.ca.gov/datasets/transit-priority-areas-2021-1/explore?location=37.773000%2C122.191730%2C9.35. 273
Agenda Item # 10.
330 Distel Circle Residential Project 145 Initial Study City of Los Altos July 2022
whether to require a project to improve the level of service, and the relevant question under CEQA is whether those improvements would result in adverse physical changes to the environment, not whether LOS has degraded below the condition considered acceptable.

The magnitude of traffic produced by a new development and the locations where that traffic would appear are estimated using a three-step process: (1) trip generation, (2) trip distribution, and (3) trip assignment. In determining project trip generation, the magnitude of traffic entering and exiting the site is estimated for the AM and PM peak hours. Trips generated by the existing developments located at the project site are then subtracted from project-generated trips to determine the project’s true effect on intersection LOS. The project would generate 296 net new trips, including 14 during the AM peak hour and 24 during the PM peak hour. More information on how project trip generation was calculated, and a summary of the trip generation rates can be found in Appendix F.

The results of the LOS analysis show that, measured against applicable municipal and CMP LOS standards, all signalized study intersections are currently operating at an acceptable LOS during the morning and afternoon peak hours. Under near-term and cumulative conditions, several signalized intersections would have a substandard LOS with or without the project being constructed. Although these intersections would have a substandard LOS in the future, the increase in average critical delay would not be greater than four seconds, which is the threshold for determining whether a project’s trips would contribute to an operation deficiency. Extensive details about the Non-CEQA LOS analysis, including methodology, trip generation, trip distribution, trip assignment, and a summary of the existing, near-term, and cumulative plus project LOS conditions are included in Appendix F.

Unsignalized Intersection Analysis
The City of Los Altos does not have an established LOS standard for unsignalized intersections. Two of the unsignalized intersections (San Antonio Road/ Jordan Avenue and Distel Circle/ El Camino Real) in the project vicinity operate at an unacceptable level under existing conditions; therefore, a signal warrant check was conducted for these intersections. The analysis concluded that the signal warrant is not met at either intersection with or without the addition of project traffic. In addition, the availability of signalized intersections in the project vicinity that can be used by motorists negates the potential need for signalization of these intersections.

Intersection Queuing
An intersection queuing analysis was completed for the project for the following turn movements:
• westbound left-turn from El Camino Real onto Distel Circle • westbound left-turn from El Camino Real onto Distel Drive Under existing and near-term conditions with project traffic, the queue for the westbound left-turn from El Camino Real onto Distel Circle was projected to be less than the available storage capacity during peak hours. During the AM peak period, the westbound left-turn from El Camino Real onto Distel Drive has an existing deficiency where the queue exceeds the storage capacity by one car. As the project would result in fewer inbound trips during the AM peak period due to the change in land use, it would not contribute to this existing deficiency. 274

Parking Assessment
Vehicle Parking
According to the parking analysis included in Appendix F, the project is estimated to require 89 parking spaces. As discussed in Section 3.1.2 , the project would provide a total of 90 vehicle parking spaces in the ground-level garage. The garage would provide 84 parking spaces in 33 mechanical lift parking stalls, which provide multiple parking spaces per stall by stacking two cars vertically, and in some cases, with a third car stacked in a pit area below grade. The parking stall dimensions, drive aisle width, and height of the garage meet all applicable City standards and would adequately serve the proposed parking configuration.

Bicycle Parking
Per the Bike Technical Guidelines provided by the VTA, it is recommended that the project provide a minimum of 30 Class I (long-term secured) and six Class II (short-term) bicycle parking spaces. The project includes a total of 45 Class I bicycle parking spaces in a secure storage room on the ground floor of the building. These spaces can be accessed through the garage or the lobby area. The project would provide six Class II bicycle spaces.

4.18 TRIBAL CULTURAL RESOURCES

4.18.1 Environmental Setting

4.18.1.1 Regulatory Framework
State
Assembly Bill 52
AB 52, effective July 2015, established a new category of resources for consideration by public agencies called Tribal Cultural Resources (TCRs). AB 52 requires lead agencies to provide notice of projects to tribes that are traditionally and culturally affiliated with the geographic area if they have requested to be notified. Where a project may have a significant impact on a TCR, consultation is required until the parties agree to measures to mitigate or avoid a significant effect on a tribal cultural resource or until it is concluded that mutual agreement cannot be reached.

Under AB 52, TCRs are defined as follows:
• Sites, features, places, cultural landscapes, sacred places, and objects with cultural value to a California Native American tribe that are also either:
o Included or determined to be eligible for inclusion in the CRHR, or o Included in a local register of historical resources as defined in Public Resources Code Section 5020.1(k).
• A resource determined by the lead agency to be a TCR.

4.18.1.2 Existing Conditions
There are no known TCRs on the project sites.94 As discussed in Section 4.5 Cultural Resources, the project site is not archaeologically sensitive.

Section 21074 as either a site, feature, place,
cultural landscape that is geographically defined in
terms of the size and scope of the landscape,

Code Section 5024.1? In applying the criteria
set forth in subdivision (c) of Public Resources
Code Section 5024.1, the lead agency shall
consider the significance of the resource to a
California Native American tribe.

Impact TCR-1: The project would not cause a substantial adverse change in the significance of a tribal cultural resource that is listed or eligible for listing in the California Register of Historical Resources, or in a local register of historical resources as defined in Public Resources Code Section 5020.1(k). (Less than Significant Impact)
A Sacred Lands File Search was conducted through the Native American Heritage Commission (NAHC) for the project site in January 2022, the search result was negative. There are no known TCRs on-site.

As previously discussed in Section 4.5 Cultural Resources, there are no known archeological resources on-site and the site has a low possibility for uncovering archeological resources. The project, as proposed, includes the following standard construction-related measure identified in Section 3.1.5.1 Standard Construction Measures to reduce impacts to archaeological resources (if discovered on-site):
• In the event that buried, or previously unrecognized archaeological deposits or materials of any kind are inadvertently exposed during any construction activity, all activity within a 50- foot radius of the find would be stopped until a qualified archaeologist can assess the find and provide recommendations for further treatment, if warranted. Preservation in place is the 277
Agenda Item # 10.

preferred treatment of an archeological resource. When preservation in place of an archeological resource is not feasible, data recovery, in accord with a data recovery plan prepared and adopted by the City, is the appropriate action. Construction and potential impacts to the area within a radius determined by the archaeologist would not recommence until the assessment is complete.

The above proposed measure, which is typically implemented by development projects, would reduce impacts to archaeological resources (including TCRs if discovered on-site) to a less than significant level by stopping construction and preparing a research design and treatment plan if any archaeological resources are found, thereby protecting the resource. Therefore, the project would not cause a substantial adverse change to a TCR. (Less than Significant Impact) Impact TCR-2: The project would not cause a substantial adverse change in the significance of a tribal cultural resource that is determined by the lead agency, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision (c) of Public Resources Code Section 5024.1.

4.19 UTILITIES AND SERVICE SYSTEMS

4.19.1 Environmental Setting

4.19.1.1 Regulatory Framework
State
State Water Code
Pursuant to the State Water Code, water suppliers providing water for municipal purposes to more than 3,000 customers or supplying more than 3,000 acre-feet (approximately 980 million gallons) of water annually must prepare and adopt an urban water management plan (UWMP) and update it every five years. As part of a UWMP, water agencies are required to evaluate and describe their water resource supplies and projected needs over a 20-year planning horizon, water conservation, water service reliability, water recycling, opportunities for water transfers, and contingency plans for drought events. California Water Service adopted its most recent UWMP for the Los Altos Suburban District in June 2021.

Assembly Bill 939
The California Integrated Waste Management Act of 1989, or AB 939, established the Integrated Waste Management Board, required the implementation of integrated waste management plans, and mandated that local jurisdictions divert at least 50 percent of solid waste generated (from 1990 levels), beginning January 1, 2000, and divert at least 75 percent by 2010. Projects that would have an adverse effect on waste diversion goals are required to include waste diversion mitigation measures.

Assembly Bill 341
AB 341 sets forth the requirements of the statewide mandatory commercial recycling program.

Businesses that generate four or more cubic yards of garbage per week and multi-family dwellings with five or more units in California are required to recycle. AB 341 sets a statewide goal for 75 percent disposal reduction by the year 2020.

Senate Bill 1383
SB 1383 establishes targets to achieve a 50 percent reduction in the level of the statewide disposal of organic waste from the 2014 level by 2020 and a 75 percent reduction by 2025. The bill grants CalRecycle the regulatory authority required to achieve the organic waste disposal reduction targets and establishes an additional target that at least 20 percent of currently disposed edible food is recovered for human consumption by 2025.

AB 1826
AB 1826 requires that multi-family residential buildings with five or more dwelling units implement an organic waste recycling program to divert organic waste generated on-site. Organic waste includes food waste, green waste, landscape and pruning waste, nonhazardous wood waste, and food-soiled paper waste that is mixed in with food waste.

California Green Building Standards Code
In January 2010, the State of California adopted the California Green Building Standards Code, establishing mandatory green building standards for all buildings in California. The code covers five categories: planning and design, energy efficiency, water efficiency and conservation, material conservation and resources efficiency, and indoor environmental quality. These standards include the following mandatory set of measures, as well as more rigorous voluntary guidelines, for new construction projects to achieve specific green building performance levels:
• Reducing indoor water use by 20 percent;
• Reducing wastewater by 20 percent;
• Recycling and/or salvaging 50 percent of nonhazardous construction and demolition debris; and
• Providing readily accessible areas for recycling by occupants.

Regional and Local
Countywide Integrated Waste Management Plan
Pursuant to AB 939, solid waste facility compliance requires that each county prepare and adopt a Countywide Integrated Waste Management Plan. The Santa Clara County Integrated Waste Management Plan (CIWMP) was approved in 1996 and contains goals, policies, and objectives aimed to ensure an effective and efficient integrated waste management system. Public Resources Code Sections 41770 and 41822, and Title 24, California Code of Regulations Section 18788 require that each countywide or regional agency integrated waste management plan (CIWMP/RAIWMP), and elements thereof, be reviewed, revised (if necessary), and submitted to the CalRecycle every five years. The last such review was completed in 2016 and concluded that despite population growth, solid waste diversion has increased, Santa Clara County has adequate disposal capacity (i.e., greater than 15 years), and no revisions to the CIWMP are warranted.95 Los Altos General Plan
The following policies in the City’s General Plan have been adopted for the purpose of avoiding or reducing impacts on utilities and service systems and are applicable to the project:

Policy Description
IWD 1.3 Review development proposals to determine whether adequate water pressure exists for existing and new development.

IWD 2.2 Review development proposals to ensure that if a project is approved, adequate sewage collection and treatment capacity is available to support such proposals.

Los Altos Municipal Code
Chapter 6.12 of the City’s Municipal Code outlines the requirements for enrolling in solid waste collection services, proper waste storage, mandatory recycling programs for both commercial and residential properties, and enforcement procedures. Chapter 6.14 of the Municipal Code details the City’s requirements for disposing of solid waste that is generated during the demolition of existing structures and the construction of new buildings in the City. Projects that are valued at $25,000 or more must divert at least 65 percent of the construction and demolition debris associated with the project from landfills in order to help the City achieve their overall waste diversion goal of 78 percent

4.19.1.2 Existing Conditions
Water Supply
The project site is served by the California Water Service Company (Cal Water) and is located within Cal Water’s Los Altos Suburban (LAS) District. Water supply for the project site is sourced from a combination of groundwater and purchased water. Approximately 21 percent of the LAS District’s provided water comes from primary groundwater production and 79 percent comes from water purchases from the Valley Water, sourced from underground aquifers, reservoirs, and the San Joaquin-Sacramento River Delta. The LAS District system includes 297 miles of mains, 65 booster pumps, and 46 storage tanks.96 The LAS District 2020 UWMP found that Cal Water has more than sufficient well capacity to meet the demands unserved by Valley Water purchases through 2045.

The project site is currently developed with an office use that has an estimated water demand of approximately 3.47 million gallons per year, or 9,500 gallons per day.97 Water is supplied to the project site by an existing eight-inch water main in Distel Circle.

Sanitary Sewer/Wastewater Treatment
The City of Los Altos’ Department of Public Works is responsible for the wastewater collection system within the City. Wastewater is conveyed to the Palo Alto Regional Water Pollution Control Plant (PARWQCP) for treatment and disposal. The PARWQCP serves the wastewater management needs of the communities of Palo Alto, Los Altos, Mountain View, East Palo Alto, Los Altos Hills, Stanford University, and East Palo Alto Sanitary District. The City owns and maintains the collection system within the City and its sphere of influence and the trunk sewer that connects the City to the 96 California Water Service Company. “2020 Urban Water Management Plan – Los Altos Suburban District”.

PARWQCP master metering station. The City’s collection system includes approximately 140 miles of sewer pipes, most of which are six-inch and eight-inch vitrified clay pipe.98 The PARWQCP has an annual treatment capacity of 39 million gallons per day (mgd), with the municipalities of Los Altos, Mountain View, and Los Altos Hills estimated to generate 4,045 acrefeet per year, or 3.6 mgd of the plant’s treatment capacity (nine percent). The PARWQCP currently receives approximately 17 mgd from all its customers.99 The PARQQCP, therefore, has approximately 22 mgd of treatment capacity available.

The existing office building is estimated to generate approximately 2.95 million gallons of wastewater per year, or 8,100 gallons per day.100 An existing six-inch sanitary sewer main in Distel Circle serves the project site.

Storm Drainage
Runoff from the project site flows into the City of Los Altos’ municipal storm drainage system via an existing two-inch reinforced concrete storm drainpipe in Distel Circle. The existing on-site storm drainage system captures and conveys runoff from the project site to the City’s storm drain system.

Flows from the project site are discharged to Adobe Creek and ultimately, the San Francisco Bay.101 Solid Waste
Solid waste collection in the City of Los Altos is provided by Mission Trail Waste Systems through a contract with the City. Mission Trail Waste Systems provides residential, commercial, and industrial collection services for garbage, recycling, and organics for the City. Mission Trail Waste Systems operates a transfer station at 1313 Memorex Drive in Santa Clara. Solid waste generated in the City is disposed of at Newby Island Sanitary Landfill (NISL) in the City of San José. As of June 2022, Newby Island Landfill had approximately 12.8 million cubic yards of capacity remaining and an estimated closure year of 2035.102
It is estimated that the existing office use generates approximately 11.27 tons of solid waste per year.

The proposed project would connect to an existing eight-inch water main in Distel Circle via new six-inch lateral lines in order to provide domestic water to the residences. Lateral connections to water lines in nearby streets would be established during grading and result in minimal impacts. (Less than Significant Impact)
Sanitary Sewer Facilities/Wastewater Treatment
The project would connect to the City’s existing sanitary sewer system. The existing sanitary sewer lines in Distel Circle would be utilized by the project to convey wastewater flows from the project to the PARWQCP. It is estimated that the project would generate 22,265 gpd of wastewater, which is a 283
Agenda Item # 10.
330 Distel Circle Residential Project 155 Initial Study City of Los Altos July 2022
net increase in 14,173 gpd of wastewater compared to existing conditions. The City requires confirmation there is sufficient capacity in the existing sewer lines serving the site and downstream to accommodate project flows.

Conditions of Approval:
• The project applicant shall submit a Sewage Capacity Study with calculations showing that the City’s existing sewer line will not exceed two-thirds full due to the project’s sewer loads.

For any segment that is calculated to exceed two-thirds full for average daily flow or for any segment that the flow is surcharged in the main due to peak flow, the applicant shall replace the sewer line with a larger sewer line.

Implementation of the above Condition of Approval would require the construction of any additional sewer mains, sewer lines, and lateral connections to ensure sewer flow would not exceed two-thirds full for average daily flow. Installation of the sewer lines for the new building would occur during grading and result in minimal impacts. The availability of treatment capacity at the PARWQCP is discussed under Impact UTL-3, and the analysis concluded that there is adequate capacity at the PARWQCP to handle the increase in wastewater generated by the project. (Less than Significant Impact)
Storm Drainage Facilities
As discussed in 4.10 Hydrology and Water Quality, the project would reduce impervious surface area on-site compared to existing conditions, resulting in a corresponding reduction of site runoff. The project would utilize a bioretention area, storm drain treatment unit, and permeable pavement to treat stormwater runoff. Based on the project’s Stormwater Control Plan, the project would meet the affordable housing development criteria from the MRP. As a result, the existing storm drainage system would continue to be able to accommodate runoff from the project site. Therefore, the proposed project would not require the construction or relocation of storm drainage facilities, aside from the lateral connections to the existing 12-inch storm drain line in Distel Circle. (Less than Significant Impact)
Electric Power, Natural Gas, and Telecommunication Facilities The site is currently served by electric power, natural gas, and telecommunication utilities. The proposed redevelopment of the site would not require the expansion of these utilities. Therefore, the proposed project would not result in a significant impact from construction or relocation of new or expanded electric power, natural gas, or telecommunication facilities. (Less than Significant Impact)
Impact UTL-2: The project would have sufficient water supplies available to serve the project and reasonably foreseeable future development during normal, dry and multiple dry years. (Less than Significant Impact)
The existing uses on the project site have a water demand of approximately 3.47 million gallons per year. The proposed project would result in water demand of approximately 9.56 million gallons per 284
Agenda Item # 10.
330 Distel Circle Residential Project 156 Initial Study City of Los Altos July 2022
year, resulting in a net increase in water demand of 6.09 million gallons per year.104 The estimated water use of the project is likely conservative (i.e., over estimated) because the project would be required to adhere to the 2019 CALGreen Code and Chapter 12.36 of the Municipal Code, which includes water efficient landscape regulations.

Water is supplied to the LAS District by the Santa Clara Valley Water District. The CalWater LAS District did not identify any substantial supply deficiencies through 2040 in its UWMP. The average annual water demand in the District between 2016 and 2020 was 11,568 acre-feet per year (3.77 billion gallons). The District estimates that annual water demand in its jurisdiction would increase to 14,197 acre-feet per year (4.63 billion gallons) by the year 2045.105 This increase in demand would be met by the estimated equivalent amount of supply water. Under single and multiply dry year scenarios, there would be no supply deficiencies. With implementation of water shortage contingency measures outlined in the LAS District UWMP, the LAS District is expected to meet the City of Los Altos’ water demands in normal, single-dry, and multiple-dry year scenarios. The LAS District UWMP utilized General Plan land uses and projected development patterns (including the proposed project) to forecast local and regional water demands; therefore, the increase in water demand generated by the project has already been accounted for in the UWMP forecast. Based on this discussion, the project would have sufficient water supplies available to serve the project and reasonably foreseeable future development during normal, dry and multiple dry years. (Less than Significant Impact)
Impact UTL-3: The project would not result in a determination by the wastewater treatment provider which serves or may serve the project that it does not have adequate capacity to serve the project’s projected demand in addition to the provider’s existing commitments. (Less than Significant Impact)
Wastewater generated by the project would be conveyed to and treated at the PARWQCP. It is estimated that the project would generate 22,265 gpd of wastewater, which is a net increase in 14,173 gpd (or 0.014 mgd) of wastewater compared to existing conditions.106 The PARWQCP has approximately 22 mgd of treatment capacity available.107 Therefore, the increase in wastewater generated by the project (0.014 mgd) would not exceed the available treatment capacity (22 mgd) at the PARWQCP.

The project is estimated to generate approximately 41.4 tons of solid waste per year.108 This amounts to a net increase of 30.13 tons of solid waste per year compared to the waste generated by the existing office building on the site.109 Given NISL’s remaining capacity (12.8 million cubic yards) and the project’s net increase in solid waste generation (30.13 tons per year, which is equivalent to

32.6 cubic yards per year), there is sufficient capacity at NISL to serve the project.110 (Less than Significant Impact)
Impact UTL-5: The project would be compliant with federal, state, or local management and reduction statutes and regulations related to solid waste. (Less than Significant Impact)
The project’s compliance with the Chapter 6.12 of the Municipal Code would ensure that project operation meets state and federal solid waste statutes and regulations. Additionally, the project would be required to collect, recycle and dispose of waste generated from construction and demolition activities per Municipal Code Chapter 6.14. During project operation, green waste, organics, and recycling collection would be provided by Mission Trail Waste Systems. For these reasons, the project would comply with AB 939, AB 32, AB 341, SB 1383, and AB 1826 and the City’s 78 percent waste diversion goal. Therefore, the proposed project would not conflict with federal, state, and local solid waste statutes and regulations. (Less than Significant Impact)

108 CalEEMod. Appendix D – Table 10.1 Solid Waste Disposal Rates. September 2016. 109 Existing solid waste disposed on the project site equals 11.27 tons per year. The project proposes to generate waste at 41.4 tons of solid waste per year, which equals an increase in 30.13 tons of solid waste per year. Source:

4.20 WILDFIRE

4.20.1 Environmental Setting

4.20.1.1 Regulatory Framework
State
Fire Hazard Severity Zones
CAL FIRE is required by law to map areas of significant fire hazards based on fuels, terrain, weather, and other relevant factors. Referred to as Fire Hazard Severity Zones (FHSZs), these maps influence how people construct buildings and protect property to reduce risk associated with wildland fires.

FHSZs are divided into areas where the state has financial responsibility for wildland fire protection, known as state responsibility areas (SRAs), and areas where local governments have financial responsibility for wildland fire protection, known as local responsibility areas (LRAs). Homeowners living in an SRA are responsible for ensuring that their property is in compliance with California’s building and fire codes. Only lands zoned for very high fire hazard are identified within LRAs.

4.20.1.2 Existing Conditions
The project site is in an urban area surrounded by existing development. The project site is not located near wildlands that could present a fire hazard. The site is not located within an identified Very High Fire Hazard Severity Zone in an SRA or a LRA.111,112

Impact
No Impact
1) Does the project have the potential to
substantially degrade the quality of the
environment, substantially reduce the habitat
of a fish or wildlife species, cause a fish or
wildlife population to drop below selfsustaining levels, threaten to eliminate a plant or animal community, substantially reduce the
number or restrict the range of a rare or
endangered plant or animal, or eliminate
important examples of the major periods of
California history or prehistory?
2) Does the project have impacts that are
individually limited, but cumulatively
considerable? (“Cumulatively considerable”
means that the incremental effects of a project
are considerable when viewed in connection
with the effects of past projects, the effects of
other current projects, and the effects of
probable future projects.)
3) Does the project have environmental effects
which will cause substantial adverse effects on
human beings, either directly or indirectly?
Impact MFS-1: The project does not have the potential to substantially degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, substantially reduce the number or restrict the range of a rare or endangered plant or animal, or eliminate important examples of the major periods of California history or prehistory. (Less than Significant Impact)
As discussed in prior sections of this Initial Study, the project as proposed (including the measures identified in Section 3.1.5.1 Standard Construction Measures) would not degrade the quality of the environment. As discussed in Section 4.4 Biological Resources, the project as proposed (which includes measures to protect nesting birds if found on- or adjacent to the site during construction activities) would not substantially affect biological resources. As discussed in Section 4.5 Cultural Resources, the project as proposed (which includes measures to protect unknown archaeological resources and TCRs if encountered on-site) would not eliminate important examples of California history or prehistory. (Less than Significant Impact)

Agenda Item # 10.
330 Distel Circle Residential Project 161 Initial Study City of Los Altos July 2022
Impact MFS-2: The project does not have impacts that are individually limited, but cumulatively considerable. (Less than Significant Impact) Under Section 15065(a)(3) of the CEQA Guidelines, a lead agency shall find that a project may have a significant effect on the environment where there is substantial evidence that the project has potential environmental effects “that are individually limited, but cumulatively considerable.” As defined in Section 15065(a)(3) of the CEQA Guidelines, cumulatively considerable means “that the incremental effects of an individual project are significant when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects.”
As discussed in Sections 4.1, 4.2, 4.12, and 4.20, the project would result in no impact to aesthetics, agricultural or forestry resources, mineral resources, or wildfire. Therefore, the project would not contribute to a cumulative impact to these resources.

In general, an individual project’s impact on broader resources including air quality, energy, GHGs, and VMT are evaluated at a cumulative level. That is, if a project results in a significant impact to air quality (specifically criteria air pollutants), energy, GHG, and VMT, the project would be considered to have a significant cumulative impact to those resources. As discussed in Sections 4.3, 4.6, 4.8, and

4.17, the project would not result in significant (individual and cumulative) impacts to those resources.

The project would result in less than significant impacts to biological resources, cultural resources, geology and soils, hazards and hazardous materials, hydrology and water quality, land use, population and housing, public services, recreational facilities, transportation, tribal cultural resources, and utilities and service systems without the imposition of mitigation measures. Future cumulative development (including the project) would be required to comply the MBTA, Fish and Game Code, and CEQA to avoid and/or minimize impacts to nesting birds. Additionally, cumulative projects would conform to the City’s Tree Protection Ordinance, which requires replacement of protected trees. As a result, the cumulative projects would not result in significant cumulative impacts to biological resources. Future cumulative development would be subject to federal, state, and local regulations pertaining to the protection of cultural resources. As a result, the cumulative projects would not result in significant cumulative impacts to archaeological resources. Future development would adhere to the CBC and recommendations of a site-specific geotechnical report; therefore, cumulative projects would not result in a significant cumulative impact to geology and soils. Cumulative projects would be required to comply with all applicable standards and regulations put in place to minimize impacts from the transport, use, storage, and disposal of hazardous materials. Therefore, the cumulative projects would not result in a significant cumulative impact due to routine transport, use, or disposal of hazardous materials. Additionally, cumulative projects would be subject to the MRP Provision C.12.f and Los Altos Municipal Code Chapter 6.15, and other local, state, and federal laws that require PCB screening and lead-based paint surveys. Therefore, cumulative projects would not result in a significant cumulative impact to hazards and hazardous materials. Future cumulative projects would be subject to the NPDES Construction General Permit or CalGreen requirements, which require control measures to reduce construction stormwater.

Cumulative projects that add or replace more than 10,000 square feet of impervious surface area, and would be required to conform with Provision C.3 of the MRP and the City’s Municipal Code. As 290
Agenda Item # 10.
330 Distel Circle Residential Project 162 Initial Study City of Los Altos July 2022
such, cumulative hydrology and water quality impacts would be less than significant. Land uses in the City are regulated through the General Plan. Future cumulative projects would be subject to the City’s design review process to ensure the final site designs and layout are consistent with the City’s General Plan and other relevant standards. Growth in the City is guided by the City’s General Plan.

Project’s that are consistent with the General Plan are assumed to be consistent with the growth projections of the General Plan. Future cumulative projects would be reviewed during the design review process for consistency with the General Plan and to ensure the cumulative development does not remove obstacles that would result in unplanned growth. Future development project would comply with General Plan Policies OSCCF 6.1, 6.3, and 6.4 which would ensure adequate police and fire protection services. Additionally, cumulative residential development would be required to pay school impact fees in accordance with California Government Code Section 65996. For these reasons, cumulative projects would not contribute to a cumulative significant public services and recreation impact. Future cumulative projects would be required to confirm sufficient water supply and wastewater treatment capacity and would to detail the exact locations for all utility connections and utility plans as part of the design review process. Therefore, cumulative projects would not result in a significant cumulative utility and service impact.

Given the above considerations, the proposed project would not result in a cumulatively considerable contribution to a significant cumulative impact. (Less than Significant Cumulative Impact) Impact MFS-3: The project does not have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly. (Less than Significant Impact)
Consistent with Section 15065(a)(4) of the CEQA Guidelines, a lead agency shall find that a project may have a significant effect on the environment where there is substantial evidence that the project has the potential to cause substantial adverse effects on human beings, either directly or indirectly.

Under this standard, a change to the physical environment that might otherwise be minor must be treated as significant if people would be significantly affected. This factor relates to adverse changes to the environment of human beings generally, and not to effects on particular individuals. While changes to the environment that could indirectly affect human beings would be represented by all of the designated CEQA issue areas, those that could directly affect human beings include air quality, geology and soils, hazards and hazardous materials, and noise. As discussed in Sections 4.3, 4.7, 4.9, and 4.13, the project as proposed (including the measures identified in Section 3.1.5.1 Standard Construction Measures) would not result in significant impacts pertaining to those resources. No substantial adverse effects on human beings would result from the project. (Less than Significant Impact)

1 Introduction
The purpose of this report is to address air quality, community health risk, and greenhouse gas (GHG) impacts associated with residential project located at 330 Distel Circle in Los Altos, California. The air quality impacts and GHG emissions would be associated with the demolition of the existing land uses at the site, construction of new building and infrastructure, and operation of the project. Air pollutant and GHG emissions associated with the construction and operation of the project were estimated using appropriate computer models. In addition, the potential project health risk impact (includes construction and operation) and the impacts of existing toxic air contaminant (TAC) sources affecting the nearby and proposed sensitive receptors were evaluated.

This analysis addresses those issues following the guidance provided by the Bay Area Air Quality Management District (BAAQMD).1

Project Description
The project site is approximately 0.87-acres and currently developed with an approximately 12,120 square foot (sf) single-story office building, landscaping, and surface parking. The project would demolish existing office building and associated surface parking to construct a new five-story apartment building. The apartment building would include ninety, 100 percent affordable apartment units. Parking would be provided in a ground-level podium parking garage containing a total of 90 vehicle parking spaces.

Setting
The project is located in Santa Clara County, which is in the San Francisco Bay Area Air Basin.

Ambient air quality standards have been established at both the State and federal level. The Bay Area meets all ambient air quality standards with the exception of ground-level ozone, respirable particulate matter (PM10), and fine particulate matter (PM2.5).

Air Pollutants of Concern
High ozone levels are caused by the cumulative emissions of reactive organic gases (ROG) and nitrogen oxides (NOX). These precursor pollutants react under certain meteorological conditions to form high ozone levels. Controlling the emissions of these precursor pollutants is the focus of the Bay Area’s attempts to reduce ozone levels. The highest ozone levels in the Bay Area occur in the eastern and southern inland valleys that are downwind of air pollutant sources. High ozone levels aggravate respiratory and cardiovascular diseases, reduce lung function, and increase coughing and chest discomfort.

Particulate matter is another problematic air pollutant of the Bay Area. Particulate matter is assessed and measured in terms of respirable particulate matter or particles that have a diameter of 10 micrometers or less (PM10) and fine particulate matter where particles have a diameter of 2.5 micrometers or less (PM2.5). Elevated concentrations of PM10 and PM2.5 are the result of both region-wide (or cumulative) emissions and localized emissions. High particulate matter levels 1 Bay Area Air Quality Management District, CEQA Air Quality Guidelines, May 2017. 304
Agenda Item # 10.
2 aggravate respiratory and cardiovascular diseases, reduce lung function, increase mortality (e.g., lung cancer), and result in reduced lung function growth in children.

Toxic Air Contaminants
Toxic air contaminants (TAC) are a broad class of compounds known to cause morbidity or mortality. TACs are found in ambient air, especially in urban areas, and are caused by industry, agriculture, fuel combustion, and commercial operations (e.g., dry cleaners). TACs are typically found in low concentrations, even near their source (e.g., diesel particulate matter [DPM] near a freeway). Because chronic exposure can result in adverse health effects, TACs are regulated at the regional, State, and federal level.

Diesel exhaust is the predominant TAC in urban air and is estimated to represent about threequarters of the cancer risk from TACs (based on the Bay Area average). According to the California Air Resources Board (CARB), diesel exhaust is a complex mixture of gases, vapors, and fine particles. This complexity makes the evaluation of health effects of diesel exhaust a complex scientific issue. Some of the chemicals in diesel exhaust, such as benzene and formaldehyde, have been previously identified as TACs by the CARB, and are listed as carcinogens either under the State's Proposition 65 or under the Federal Hazardous Air Pollutants programs. The most recent Office of Environmental Health Hazard Assessment (OEHHA) risk assessment guidelines were published in February of 2015.2 See Attachment 1 for a detailed
description of the community risk modeling methodology used in this assessment.

Sensitive Receptors
There are groups of people more affected by air pollution than others. CARB has identified the following persons who are most likely to be affected by air pollution: children under 16, the elderly over 65, athletes, and people with cardiovascular and chronic respiratory diseases. These groups are classified as sensitive receptors. Locations that may contain a high concentration of these sensitive population groups include residential areas, hospitals, daycare facilities, elder care facilities, and elementary schools. For cancer risk assessments, infants and children are the most sensitive receptors, since they are more susceptible to cancer causing TACs. Residential locations are assumed to include infants and small children.

The closest sensitive receptors to the project site are the residents in the single-family homes to the southwest and south of the site. There are other single-and multi-family residences to the north, east, and west of the site at further distances. In addition, there are children at the Mountain ViewLos Altos Montessori Children's Center (2-6 years old) to the northeast of the site. This project would also introduce new sensitive receptors (i.e., residents).

3 Regulatory Agencies
Federal Regulations
The United States Environmental Protection Agency (EPA) sets nationwide emission standards for mobile sources, which include on-road (highway) motor vehicles such trucks, buses, and automobiles, and non-road (off-road) vehicles and equipment used in construction, agricultural, industrial, and mining activities (such as bulldozers and loaders). The EPA also sets nationwide fuel standards. California also has the ability to set motor vehicle emission standards and standards for fuel used in California, as long as they are the same or more stringent than the Federal standards.

In the past decade the EPA has established a number of emission standards for on- and non-road heavy-duty diesel engines used in trucks and other equipment. This was done in part because diesel engines are a significant source of nitrogen oxides, or NOX, and particulate matter (PM10 and PM2.5) and because the EPA has identified diesel particulate matter as a probable carcinogen.

Implementation of the heavy-duty diesel on-road vehicle standards and the non-road diesel engine standards are estimated to reduce PM and NOX emissions from diesel engines up to 95 percent in 2030 when the heavy-duty vehicle fleet is completely replaced with newer heavy-duty vehicles that comply with these emission standards.3
In concert with the diesel engine emission standards, the EPA has also substantially reduced the amount of sulfur allowed in diesel fuels. The sulfur contained in diesel fuel is a significant contributor to the formation of particulate matter in diesel-fueled engine exhaust. The new standards reduced the amount of sulfur allowed by 97 percent for highway diesel fuel (from 500 parts per million by weight [ppmw] to 15 ppmw), and by 99 percent for off-highway diesel fuel (from about 3,000 ppmw to 15 ppmw). The low sulfur highway fuel (15 ppmw sulfur), also called ultra-low sulfur diesel (ULSD) is currently required for use by all vehicles in the U.S.

All of the above Federal diesel engine and diesel fuel requirements have been adopted by California, in some cases with modifications making the requirements more stringent or the implementation dates sooner.

State Regulations
To address the issue of diesel emissions in the state, CARB developed the Risk Reduction Plan to Reduce Particulate Matter Emissions from Diesel-Fueled Engines and Vehicles4 . In addition to
requiring more stringent emission standards for new on-road and off-road mobile sources and stationary diesel-fueled engines to reduce particulate matter emissions by 90 percent, a significant component of the plan involves application of emission control strategies to existing diesel 3 USEPA, 2000. Regulatory Announcement, Heavy-Duty Engine and Vehicle Standards and Highway Diesel Fuel Sulfur Control Requirements. EPA420-F-00-057. December. 4 California Air Resources Board, 2000. Risk Reduction Plan to Reduce Particulate Matter Emissions from DieselFueled Engines and Vehicles. October. 306
Agenda Item # 10.
4 vehicles and equipment. Many of the measures of the Diesel Risk Reduction Plan have been approved and adopted, including the Federal on-road and non-road diesel engine emission standards for new engines, as well as adoption of regulations for low sulfur fuel in California.

CARB has adopted and implemented a number of regulations for stationary and mobile sources to reduce emissions of DPM. Several of these regulatory programs affect medium and heavy-duty diesel trucks that represent the bulk of DPM emissions from California highways. CARB regulations require on-road diesel trucks to be retrofitted with particulate matter controls or replaced to meet 2010 or later engine standards that have much lower DPM and PM2.5 emissions.

This regulation will substantially reduce these emissions between 2013 and 2023. While new trucks and buses will meet strict federal standards, this measure is intended to accelerate the rate at which the fleet either turns over so there are more cleaner vehicles on the road or i s retrofitted to meet similar standards. With this regulation, older, more polluting trucks would be removed from the roads sooner.

CARB has also adopted and implemented regulations to reduce DPM and NOX emissions from inuse (existing) and new off-road heavy-duty diesel vehicles (e.g., loaders, tractors, bulldozers, backhoes, off-highway trucks, etc.). The regulations apply to diesel-powered off-road vehicles with engines 25 horsepower (hp) or greater. The regulations are intended to reduce particulate matter and NOX exhaust emissions by requiring owners to turn over their fleet (replace older equipment with newer equipment) or retrofit existing equipment in order to achieve specified fleetaveraged emission rates. Implementation of this regulation, in conjunction with stringent Federal off-road equipment engine emission limits for new vehicles, will significantly reduce emissions of DPM and NOX in the future.

Bay Area Air Quality Management District (BAAQMD)
BAAQMD has jurisdiction over an approximately 5,600-square mile area, commonly referred to as the San Francisco Bay Area (Bay Area). The District’s boundary encompasses nine San Francisco Bay Area counties, including Alameda County, Contra Costa County, Marin County, San Francisco County, San Mateo County, Santa Clara County, Napa County, southwestern Solano County, and southern Sonoma County.

BAAQMD is the lead agency in developing plans to address attainment and maintenance of the National Ambient Air Quality Standards (NAAQS) and California Ambient Air Quality Standards (CAAQS). The District also has permit authority over most types of stationary equipment utilized for the proposed project. The BAAQMD is responsible for permitting and inspection of stationary sources; enforcement of regulations, including setting fees, levying fines, and enforcement actions; and ensuring that public nuisances are minimized.

BAAQMD’s Community Air Risk Evaluation (CARE) program was initiated in 2004 to evaluate and reduce health risks associated with exposures to outdoor TACs in the Bay Area.5 The program
examines TAC emissions from point sources, area sources, and on-road and off-road mobile sources with an emphasis on diesel exhaust, which is a major contributor to airborne health risk in 5 See BAAQMD: https://www.baaqmd.gov/community-health/community-health-protection-program/communityair-risk-evaluation-care-program , accessed 2/18/2021. 307

5 California. The CARE program is an on-going program that encourages community involvement and input. The technical analysis portion of the CARE program is being implemented in three phases that includes an assessment of the sources of TAC emissions, modeling and measurement programs to estimate concentrations of TAC, and an assessment of exposures and health risks.

Throughout the program, information derived from the technical analyses will be used to focus emission reduction measures in areas with high TAC exposures and high density of sensitive populations. Risk reduction activities associated with the CARE program are focused on the most at-risk communities in the Bay Area. Overburdened communities are areas located (i) within a census tract identified by the California Communities Environmental Health Screening Tool (CalEnviroScreen), Version 4.0 implemented by OEHHA, as having an overall CalEnviroScreen score at or above the 70th percentile, or (ii) within 1,000 feet of any such census tract. 6 The
BAAQMD has identified six communities as impacted: Concord, Richmond/San Pablo, Western Alameda County, San José, Redwood City/East Palo Alto, and Eastern San Francisco. The project site is not within a CARE area and not within a BAAQMD overburdened area as identified by CalEnviroScreen since the Project site is scored at the one percentile.

The BAAQMD California Environmental Quality Act (CEQA) Air Quality Guidelines7 were
prepared to assist in the evaluation of air quality impacts of projects and plans proposed within the Bay Area. The guidelines provide recommended procedures for evaluating potential air impacts during the environmental review process consistent with CEQA requirements including thresholds of significance, mitigation measures, and background air quality information. They also include assessment methodologies for TACs, odors, and greenhouse gas (GHG) emissions. Attachment 1 includes detailed community risk modeling methodology.

City of Los Altos General Plan 2002-2020
The City of Los Altos General Plan 2002-2020 includes goals, policies, and actions to reduce exposure of the City’s sensitive population to exposure of air pollution, toxic air contaminants, and GHG emissions. The following goals, policies, and actions are applicable to the proposed project:

Goal 8: Maintain or improve air quality in Los Altos.

Policy 8.1: Support the principles of reducing air pollutants through land use, transportation, and energy use planning.

Policy 8.2: Encourage transportation modes that minimize contaminant emissions from motor vehicle use.

Policy 8.3: Interpret and implement the General Plan to be consistent with the regional Bay Area Air Quality Management Plan, as periodically updated. 6 See BAAQMD: https://www.baaqmd.gov/~/media/dotgov/files/rules/reg-2-permits/2021- amendments/documents/20210722_01_appendixd_mapsofoverburdenedcommunities-pdf.pdf?la=en , accessed 10/1/2021.

Significance Thresholds
In June 2010, BAAQMD adopted thresholds of significance to assist in the review of projects under CEQA and these significance thresholds were contained in the District’s 2011 CEQA Air Quality Guidelines. These thresholds were designed to establish the level at which BAAQMD believed air pollution emissions would cause significant environmental impacts under CEQA. The thresholds were challenged through a series of court challenges and were mostly upheld.

BAAQMD updated the CEQA Air Quality Guidelines in 2017 to include the latest significance thresholds that were used in this analysis are summarized in Table 1. Community risks are considered significant if they exceed these levels.

7 NEPA/HUD Significance Thresholds
The Federal Clean Air Act governs air quality in the United States. In addition to being subject to federal requirements, air quality in California is also governed by more stringent regulations under the California Clean Air Act. At the Federal level, the United States Environmental Protection Agency (USEPA) administers the Clean Air Act. The California Clean Air Act is administered by the CARB at the State level and by the Air Quality Management Districts at the regional and local levels. BAAQMD regulates air quality at the regional level, which includes the nine-county Bay Area.

The federal Clean Air Act requires each state to identify areas that have ambient air quality in violation of federal standards. States are required to develop, adopt, and implement a state implementation plan (SIP) to achieve, maintain, and enforce federal ambient air quality standards in these nonattainment areas. SIP elements are developed on a pollutant-by-pollutant basis whenever one or more air quality standards are being violated. In California, local and regional air pollution control agencies have primary responsibility for developing SIPs, generally in coordination with local and regional land use and transportation planning agencies. BAAQMD is the responsible regional air pollution control agency in the San Francisco Bay Area.

An area’s compliance with national ambient air quality standards under the Clean Air Act is categorized as nonattainment, attainment (better than national standards), unclassifiable, or attainment/cannot be classified. The unclassified designation includes attainment areas that comply with federal standards, as well as areas for which monitoring data are lacking. Unclassified areas are treated as attainment areas for most regulatory purposes. Simple attainment designations generally are used only for areas that transition from nonattainment status to attainment status.

Areas that have been reclassified from nonattainment to attainment of federal air quality standards are automatically considered maintenance areas, although this designation is seldom noted in status listings. The San Francisco Bay Area is designated as nonattainment for the federal 8-hour ozone standard and the 24-hour PM2.5 standard. The San Francisco Bay Area is designated as attainment or unclassified for the other national ambient air quality standards.

With respect to the state ambient air quality standards, California classifies areas as attainment, nonattainment, nonattainment-transitional, or unclassified. The San Francisco Bay Area is designated as nonattainment for the state ozone, inhalable particulate matter (PM10), and PM2.5 standards and as attainment or unclassified for the other state ambient air quality standards. The predominant regulation that guides assessment of air quality impacts of federal actions is the General Conformity Rule, established under the Clean Air Act (Section 176(c)(4)). The General Conformity Rule ensures that the actions taken by federal agencies in nonattainment and maintenance areas do not interfere with a state’s plans to meet national standards for air quality.

The project area is located within the San Francisco Bay Area Air Basin, which is designated as a nonattainment area for the federal 8-hour ozone standard and the federal PM2.5 standard. The air basin is designated as a maintenance area with respect to the federal carbon monoxide (CO) standards.

In keeping with the General Conformity Rule process, this assessment applies the appropriate de minimis thresholds of the Rule as they apply to the San Francisco Bay Area Air Basin for ozone 310
Agenda Item # 10.
8 precursors, PM2.5, and CO. The de minimis thresholds for these three pollutants in the San Francisco Bay Area Air Basin are 100 tons per year for each pollutant or precursor pollutant (i.e., NOx, ROG, and PM2.5).

AIR QUALITY IMPACTS AND MITIGATION MEASURES
Impact AIR-1: Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or state ambient air quality standard? The Bay Area is considered a non-attainment area for ground-level O3 and PM2.5 under both the Federal Clean Air Act and the California Clean Air Act. The area is also considered non-attainment for PM10 under the California Clean Air Act, but not the federal act. The area has attained both State and Federal ambient air quality standards for carbon monoxide. As part of an effort to attain and maintain ambient air quality standards for O3, PM2.5 and PM10, the BAAQMD has established thresholds of significance for these air pollutants and their precursors. These thresholds are for O3 precursor pollutants (ROG and NOx), PM10, and PM2.5 and apply to both construction period and operational period impacts.

Construction Period Emissions
The California Emissions Estimator Model (CalEEMod) Version 2020.4.0 was used to estimate emissions from on-site construction activity, construction vehicle trips, and evaporative emissions.

The project land use types, size, and anticipated construction schedule were input to CalEEMod.

The CARB EMission FACtors 2021 (EMFAC2021) model was used to predict emissions from construction traffic, which includes worker travel, vendor trucks, and haul trucks.8 The CalEEMod model output along with construction inputs are included in Attachment 2 and EMFAC2021 vehicle emissions modeling outputs are included in Attachment 3.

CalEEMod Inputs
Land Use Inputs
The proposed project land uses were entered into CalEEMod as described in Table 2.

Project Land Uses Size Units Square Feet (sf) Acreage
Apartments Mid Rise 90 Dwelling Units 97,970 0.87 Enclosed Parking with Elevator 90 Parking Spaces 18,130 Construction Inputs

CalEEMod computes annual emissions for construction that are based on the project type, size, and acreage. The model provides emission estimates for both on-site and off-site construction 8 See CARB’s EMFAC2021 Emissions Inventory at https://arb.ca.gov/emfac/emissions-inventory 311
Agenda Item # 10.
9 activities. On-site activities are primarily made up of construction equipment emissions, while offsite activity includes worker, hauling, and vendor traffic.

The CalEEMod model generates a default set of construction assumptions for “typical construction site scenarios”; however, these are not appropriate for a project like this that involves demolition, excavation, and vertical construction on a relatively small site.9 For this project, the construction build-out scenario, including equipment list and schedule, were based on project-specific construction information provided by the project applicant. The project construction equipment worksheet provided by the applicant included the schedule for each phase (included in Attachment 2). Within each phase, the quantity of equipment to be used along with the average hours per day and total number of workdays was based on provided information. The construction schedule assumed that the earliest possible start date would be January 2023 and the project would be built out over a period of approximately 20 months or 583 construction workdays. The earliest year of operation was assumed to be 2025.

Construction Truck Traffic Emissions
Construction would produce traffic in the form of worker trips and truck traffic. The traffic-related emissions are based on worker and vendor trip estimates produced by CalEEMod and haul trips that were computed based on the estimate of demolition material to be exported, soil material imported and/or exported to the site, and the estimate of cement and asphalt truck trips. CalEEMod provides daily estimates of worker and vendor trips for each applicable phase. The total trips for those were computed by multiplying the daily trip rate by the number of days in that phase. Haul trips for demolition and grading were estimated from the provided demolition and grading volumes and assuming each truck could carry 10 tons per load. The number of concrete and asphalt total round haul trips were provided for the project and converted to total one-way trips, assuming two trips per delivery.

The latest version of the CalEEMod model is based on the older version of the CARB EMFAC2017 motor vehicle emission factor model. This model has been superseded by the EMFAC2021 model; however, CalEEMod has not been updated to include EMFAC2021. The construction traffic information was combined with EMFAC2021 motor vehicle emissions factors.

EMFAC2021 provides aggregate emission rates in grams per mile for each vehicle type. The vehicle mix for this study was based on CalEEMod defaults, where worker trips are assumed to be comprised of light-duty autos (EMFAC category LDA) and light duty trucks (EMFAC category LDT1 and LDT2). Vendor trips are comprised of delivery and large trucks (EMFAC category MHDT and HHDT) and haul trips, including cement trucks, are comprised of large trucks (EMFAC category HHDT). Travel distances are based on CalEEMod default lengths, which are

10.8 miles for worker travel, 7.3 miles for vendor trips and 20 miles for hauling (demolition material export and soil import/export). Since CalEEMod does not address cement or asphalt trucks, these were treated as vendor travel distances. Each trip was assumed to include an idle time of 5 minutes. Emissions associated with vehicle starts were also included. On-road emission rates 9 SCAQMD. 2005. Sample Construction Scenarios for Projects Less than Five Acres in Size February.

Summary of Computed Construction Emissions
Average daily emissions were annualized for each year of construction by dividing the annual construction emissions by the number of active workdays during that year. Table 4 shows the unmitigated annualized average daily construction emissions of ROG, NOX, PM10 exhaust, and PM2.5 exhaust during construction of the project. As indicated in Table 4, predicted unmitigated annualized project construction emissions would not exceed the BAAQMD significance thresholds during any year of construction. In addition, the calculated construction period emissions would not exceed the NEPA de minimis thresholds.

11 Construction activities, particularly during site preparation and grading, would temporarily generate fugitive dust in the form of PM10 and PM2.5. Sources of fugitive dust would include disturbed soils at the construction site and trucks carrying uncovered loads of soils. Unless properly controlled, vehicles leaving the site would deposit mud on local streets, which could be an additional source of airborne dust after it dries. The BAAQMD CEQA Air Quality Guidelines consider these impacts to be less-than-significant if best management practices are implemented to reduce these emissions. Mitigation Measure AQ-1 would implement BAAQMD-recommended standard and enhanced best management practices needed to control PM2.5 concentrations at nearby sensitive receptors.

Mitigation Measure AQ-1: Implement BAAQMD-Recommended Standard and Enhanced Measures to Control Particulate Matter Emissions during Construction.

Measures to reduce fugitive dust (i.e., PM2.5) emissions from construction are recommended to and ensure that health impacts to nearby sensitive receptors are minimized. During any construction period ground disturbance, the applicant shall ensure that the project contractor implements both basic and additional measures to control dust and exhaust. Implementation of the dust control measures recommended by BAAQMD and listed below would reduce the air quality impacts associated with grading and new construction to a less-than-significant level. The contractor shall implement the following standard and enhanced best management practices:

1. All exposed surfaces shall be watered at a frequency adequate to maintain minimum soil moisture of 12 percent. Moisture content can be verified by lab samples or moisture probe.

2. All haul trucks transporting soil, sand, or other loose material off-site shall be covered.

3. All visible mud or dirt track-out onto adjacent public roads shall be removed using wet power vacuum street sweepers at least once per day. The use of dry power sweeping is prohibited.

Effectiveness of Mitigation Measure AQ-1
Mitigation Measure AQ-1 represents standard and enhanced mitigation measures that would achieve greater than an 80 percent reduction in on-site fugitive PM2.5 emissions. These measures are consistent with recommendations in the BAAMQD CEQA Guidance for providing “best management practices” to control construction emissions.

Operational Period Emissions
Operational air emissions from the project would be generated primarily from autos driven by future residents. Evaporative ROG emissions from architectural coatings and maintenance products (classified as consumer products) are also associated with these types of projects.

CalEEMod was used to estimate emissions from operation of the proposed project assuming full build-out.

CalEEMod Inputs
Land Uses
The project land uses were input to CalEEMod as described above for the construction period modeling.

Model Year
Emissions associated with vehicle travel depend on the year of analysis because emission control technology requirements are phased-in over time. Therefore, the earlier the year analyzed in the model, the higher the emission rates utilized by CalEEMod. The earliest year of full operation would be 2025 if construction begins in 2023. Emissions associated with build-out later than 2025 would be lower.

Agenda Item # 10.
13 Traffic Information
CalEEMod allows the user to enter specific vehicle trip generation rates. Therefore, the projectspecific daily trip generation rate provided by the traffic consultant was entered into the model.10 The project would produce approximately 433 daily trips. When considering the Housing Near Major Bus Stop Reduction adjustments and the 131 existing use trips applied in the traffic analysis, the project would then produce 296 net daily trips. The daily trip generation was calculated using the size of the project and the adjusted total automobile trips. The Saturday and Sunday trip rates were adjusted by multiplying the ratio of the CalEEMod default rates for Saturday and Sunday trips to the default weekday rate with the project-specific daily weekday trip rate. The default trip lengths and trip types specified by CalEEMod were used.

EMFAC2021 Adjustment
The vehicle emission factors and fleet mix used in CalEEMod are based on EMFAC2017, which is an older CARB emission inventory for on road and off-road mobile sources. Since the release of CalEEMod Version 2020.4.0, new emission factors have been produced by CARB.

EMFAC2021 became available for use in January 2021. It includes the latest data on California’s car and truck fleets and travel activity. The CalEEMod default vehicle emission factors and fleet mix were updated using the emission rates and fleet mix from EMFAC2021. On road emission rates from 2025 Santa Clara County were used (See Attachment 3). More details about the updates in emissions calculation methodologies and data are available in the EMFAC2021 Technical Support Document.11
Energy
CalEEMod defaults for energy use were used, which include the 2019 Title 24 Building Standards.

GHG emissions modeling includes those indirect emissions from electricity consumption. The model has a default rate of 2 pounds of CO2 per megawatt of electricity produced, which is based on Silicon Valley Clean Energy (SVCE) 2019 emissions rate.

The City of Los Altos adopted reach code ordinances in November 2020 that promotes building electrification and prohibits the use of natural gas infrastructure in new buildings.12 This ordinance applies to any new residential and commercial construction starting January 26, 2021. All project natural gas use was set to zero and assigned to electricity use in CalEEMod.

Wood-Burning Devices
CalEEMod default inputs assume new residential construction would include woodburning fireplaces and stoves. The project would not include wood-burning devices, as these devices are 10 Email correspondence with Natalie Noyes, AICP, Senior Project Manager, David J. Powers & Associates, Inc., March 15, 2022.

14 prohibited by BAAQMD Regulation 6, Rule 3.13 Therefore, the number of woodstoves and woodburning fireplaces in CalEEMod were set to zero.

Other Inputs
Default model assumptions for emissions associated with solid waste generation and water/wastewater use were applied to the project. Water/wastewater use was changed to 100 percent aerobic/anerobic conditions to represent wastewater treatment plant conditions, as the project site would not send wastewater to septic tanks or facultative lagoons.

Existing Uses
The existing site consist of a single-story office building and associated surface parking. A CalEEMod model run was developed to compute emissions from use of the existing land uses in 2022. Inputs for the existing conditions scenario included 12,120-sf entered as “General Office Building” and 0.59 acres entered as “Parking Lot”. The existing trip generation rates and other inputs were applied to the existing modeling in the same manner described for the proposed project.

Summary of Computed Operational Emissions
Annual emissions were predicted using CalEEMod and daily emissions were estimating assuming 365 days of operation. Table 5 shows unmitigated net average daily operational emissions of ROG, NOX, total PM10, and total PM2.5 during operation of the project. The unmitigated operational period emissions would not exceed the BAAQMD significance thresholds. In addition, the calculated operational period emissions would not exceed the NEPA de minimis thresholds.

Impact AIR-2: Expose sensitive receptors to substantial pollutant concentrations? Project impacts related to increased community risk can occur either by introducing a new source of TACs with the potential to adversely affect existing sensitive receptors in the project vicinity or by significantly exacerbating existing cumulative TAC impacts. This project would introduce new 13 Bay Area Air Quality Management District, https://www.baaqmd.gov/~/media/dotgov/files/rules/regulation-6- rule-3/documents/20191120_r0603_final-pdf.pdf?la=en

Agenda Item # 10.
15 sources of TACs during construction (i.e., on-site construction and truck hauling emissions) and operation (i.e., mobile and stationary sources).

Project construction activity would generate dust and equipment exhaust that would affect nearby sensitive receptors. The project would not include the installation of any stationary TAC emissions sources (i.e., generators) but would generate some traffic consisting of mostly light-duty gasolinepowered vehicles, which would produce TAC and air pollutant emissions.

Project impacts to existing sensitive receptors were addressed for temporary construction activities and long-term operational conditions. There are also several sources of existing TACs and localized air pollutants in the vicinity of the project. The impact of the existing sources of TAC was also assessed in terms of the cumulative risk that includes the project contribution, as well as the risk on the new sensitive receptors introduced by the project.

Community Risk Methodology for Construction
Community risk impacts were addressed by predicting increased cancer risk, the increase in annual PM2.5 concentrations and computing the Hazard Index (HI) for non-cancer health risks. The risk impacts from the project are the combination of risks from construction and operation sources.

These sources include on-site construction activity, construction truck hauling, and increased traffic from the project. To evaluate the increased cancer risks from the project, a 30-year exposure period was used, per BAAQMD guidance,14 with the sensitive receptors being exposed to both project construction and operation emissions during this timeframe.

The project increased cancer risk is computed by summing the project construction cancer risk and operation cancer risk contributions. Unlike, the increased maximum cancer risk, the annual PM2.5 concentration and HI values are not additive but based on the annual maximum values for the entirety of the project. The project maximally exposed individual (MEI) is identified as the sensitive receptor that is most impacted by the project’s construction and operation.

The methodology for computing community risks impacts is contained in Attachment 1. This involved the calculation of TAC and PM2.5 emissions, dispersion modeling of these emissions, and computations of cancer risk and non-cancer health effects.

Modeled Sensitive Receptors

Receptors for this assessment included locations where sensitive populations would be present for extended periods of time (i.e., chronic exposures). This includes the existing residences surrounding the site and the students at the school to the northeast of the project site, as shown in Figure 1. Residential receptors are assumed to include all receptor groups (i.e., third trimester, infants, children, and adults) with almost continuous exposure to project emissions. Community risks were also computed for children at the Mountain View-Los Altos Montessori Children's Center (2-6 years old).

Agenda Item # 10.
16 Community Health Risk from Project Construction
Construction equipment and associated heavy-duty truck traffic generates diesel exhaust, which is a known TAC. These exhaust air pollutant emissions would not be considered to contribute substantially to existing or projected air quality violations. Construction exhaust emissions may still pose health risks for sensitive receptors such as surrounding residents. The primary community risk impacts associated with construction emissions are cancer risk and exposure to PM2.5. Diesel exhaust (i.e., DPM) poses both a potential health and nuisance impact to nearby receptors. A health risk assessment of the project construction activities was conducted that evaluated potential health effects to nearby sensitive receptors from construction emissions of DPM and PM2.5.
15 This assessment included dispersion modeling to predict the off-site and on-site concentrations resulting from project construction, so that increased cancer risks and non-cancer health effects could be evaluated.

Construction Emissions
The CalEEMod and EMFAC2021 models provided total annual PM10 exhaust emissions (assumed to be DPM) for the off-road construction equipment and for exhaust emissions from on-road vehicles, with total DPM emissions from all construction stages estimated to be 0.23 tons (463 pounds). The on-road emissions are a result of haul truck travel during demolition and grading activities, worker travel, and vendor deliveries during construction. A trip length of half a mile was used to represent vehicle travel while at or near the construction site. It was assumed that these emissions from on-road vehicles traveling at or near the site would occur at the construction site.

Fugitive PM2.5 dust emissions were calculated by CalEEMod and EMFAC2021 to be 0.36 tons (723 pounds) for the overall construction period.

Dispersion Modeling
The U.S. EPA AERMOD dispersion model was used to predict DPM and PM2.5 concentrations at sensitive receptors (i.e., residences, school) in the vicinity of the project construction area. The AERMOD dispersion model is a BAAQMD-recommended model for use in modeling analysis of these types of emission activities for CEQA projects. 16,17 Emission sources for the construction site were grouped into two categories: exhaust emissions of DPM and fugitive PM2.5 dust emissions.

Combustion equipment DPM exhaust emissions were modeled as a series of point sources with a nine-foot release height (construction equipment exhaust stack height) placed at 20 feet (6 meter) intervals throughout the construction site. This resulted in 107 individual point sources being used to represent mobile equipment DPM exhaust emissions in the construction area, with DPM emissions occurring throughout the project construction site. In addition, the following stack 15 DPM is identified by California as a toxic air contaminant due to the potential to cause cancer. 16 BAAQMD, 2012, Recommended Methods for Screening and Modeling Local Risks and Hazards, Version 3.0.

Agenda Item # 10.
17 parameters were used: a vertical release, a stack diameter of 2.5 inches, an exhaust temperature of 918˚F, and an exit velocity of 309 feet per second. Since these are point sources, plume rise is calculated by the AERMOD dispersion model. Emissions from vehicle travel on- and off-site were also distributed among the point sources throughout the site. The locations of the point sources used for the modeling are identified in Figure 1.

For modeling fugitive PM2.5 emissions, an area source was used with a near-ground level release height of 7 feet (2 meters). Fugitive dust emissions at construction sites come from a variety of sources, including truck and equipment travel, grading activities, truck loading (with loaders) and unloading (rear or bottom dumping), loaders and excavators moving and transferring soil and other materials, etc. All of these activities result in fugitive dust emissions at various heights at the point(s) of generation. Once generated, the dust plume will tend to rise as it moves downwind across the site and exit the site at a higher elevation than when it was generated. For all these reasons, a 7-foot release height was used as the average release height across the construction site.

Emissions from the construction equipment and on-road vehicle travel were distributed throughout the modeled area sources.

The modeling used a five-year data set (2013-2017) of hourly meteorological data from the Moffett Federal Airfield that was prepared for use with the AERMOD model by BAAQMD. Construction emissions were modeled as occurring daily between 7:00 a.m. to 4:00 p.m., when the majority of construction activity would occur as provided by the applicant. Annual DPM and PM2.5 concentrations from construction activities during the 2023-2024 period were calculated using the model. DPM and PM2.5 concentrations were calculated at nearby sensitive receptors. Receptor heights of 5 feet (1.5 meters) and 15 feet (4.5 meters) were used to represent the breathing height on the first and second floors of nearby single- and multi-family residences.18 A receptor height of 3 feet (1 meter) was used to represent the breathing height of children at the school.

Summary of Construction Community Risk Impacts
The maximum increased cancer risks were calculated using the modeled TAC concentrations combined with the OEHHA guidance for age sensitivity factors and exposure parameters as recommended by BAAQMD, as described in Attachment 1. Non-cancer health hazards and maximum PM2.5 concentrations were also calculated and identified. Age-sensitivity factors reflect the greater sensitivity of infants and small children to cancer causing TACs. Third trimester, infant, child, and adult exposures were assumed to occur at all residences during the entire construction period. Children at the school were assumed to be 2-6 years old. The child (ages 2 through 16 years old) cancer risk parameters were used to calculate the increased cancer risk for the school students.

The maximum modeled annual PM2.5 concentration was calculated based on combined exhaust and fugitive concentrations. The maximum computed HI values was based on the ratio of the maximum DPM concentration modeled and the chronic inhalation reference exposure level of 5 µg/m3. 18 Bay Area Air Quality Management District, 2012, Recommended Methods for Screening and Modeling Local Risks and Hazards, Version 3.0.

Agenda Item # 10.
18 The maximum modeled annual DPM and PM2.5 concentrations were identified at nearby sensitive receptors to find the maximally exposed individuals (MEI). Results of this assessment indicated that the construction MEI was located on the first floor (5 feet above ground) of a single-family residence to the south of the project. The location of the MEI and nearby sensitive receptors are shown in Figure 1. Table 6 summarizes the maximum cancer risks, PM2.5 concentrations, and health hazard indexes for project related construction activities. Attachment 4 to this report includes the emission calculations used for the construction modeling and the cancer risk calculations.

Additionally, modeling was conducted to predict the cancer risks, non-cancer health hazards, and maximum PM2.5 concentrations associated with construction activities at the nearby school. The maximum increased cancer risks were adjusted using child exposure parameters for receptors at the school. The unmitigated cancer risk, PM2.5 concentration, and HI at the nearby school does not exceed their respective BAAQMD single-source significance thresholds.

Community Risks from Project Operation
Stationary equipment that could emit substantial TACs (e.g., emergency generators) are not planned for this project. Diesel powered vehicles are the primary concern with local trafficgenerated TAC impacts. Per BAAQMD recommended risks and methodology, a road with less than 10,000 total vehicle per day is considered a low-impact source of TACs.19 This project would generate 433 daily trips or 296 net daily trips when taking into account the existing office land use.20 The project traffic would be dispersed on the roadway system with a majority of the trips being from light-duty vehicles (i.e., passenger automobiles), which is a fraction of 10,000 daily vehicles. In addition, projects with the potential to cause or contribute to increased cancer risk from traffic include those that have attract high numbers of diesel-powered on road trucks or use off-road diesel equipment on site, such as a distribution center, a quarry, or a manufacturing facility, may potentially expose existing or future planned receptors to substantial cancer risk levels and/or health hazards. This is not a project of concern for non-BAAQMD permitted mobile sources. Therefore, emissions from project traffic are considered negligible and not included within this analysis.

Summary of Project-Related Community Risks at the Off-Site Project MEI For this project, the sensitive receptor identified in Figure 1 as the construction MEI is also the project MEI. At this location, the MEI would be exposed to emissions from 2 years of construction.

The annual PM2.5 concentration and HI values are based on an annual maximum risk for the entirety of the project.

As shown in Table 6, the unmitigated maximum cancer risks and annual PM2.5 concentration from construction activities at the MEI location would exceed the respective BAAQMD single-source 19 BAAQMD, 2012, Recommended Methods for Screening and Modeling Local Risks and Hazards, Version 3.0.

19 significance thresholds. However, with the incorporation of the Mitigation Measure AQ-1 and AQ2, the mitigated cancer risk and annual PM2.5 concentration would no longer exceed the BAAQMD single-source significance thresholds. The unmitigated HI at the MEI does not exceed its respective BAAQMD single-source significance threshold.

20 Cumulative Community Risks of all TAC Sources at the Off-Site Project MEI Community health risk assessments typically look at all substantial sources of TACs that can affect sensitive receptors that are located within 1,000 feet of the project site (i.e., influence area). These sources include rail lines, freeways or highways, busy surface streets, and stationary sources identified by BAAQMD.

A review of the project area and based on provided traffic information indicated that traffic on El Camion Real would exceed 10,000 vehicles per day. Other nearby streets would have less than 10,000 vehicles per day. A review of BAAQMD’s stationary source map website identified no stationary sources with the potential to affect the project MEI. Figure 2 shows the location of the sources affecting the MEI. Community risk impacts from these sources upon the MEI are reported in Table 7. Details of the modeling and community risk calculations are included in Attachment 5.

Figure 2. Project Site and Nearby TAC and PM2.5 Sources Local Roadways – El Camino Real
A refined analysis of potential health impacts from vehicle traffic on the El Camino Real was conducted. This refined analysis involved predicting emissions for the traffic volume and mix of 323

21 vehicle types on the roadway near the project site and using an atmospheric dispersion model to predict exposure to TACs. The associated cancer risks were then computed based on the modeled exposures. Attachment 1 includes a description of how community risk impacts, including cancer risk are computed.

Traffic Emissions Modeling
This analysis involved the development of DPM, organic TACs, and PM2.5 emissions for traffic on El Camino Real using the Caltrans version of the CARB EMFAC2017 emissions model, known as CT-EMFAC2017. CT-EMFAC2017 provides emission factors for mobile source criteria pollutants and TACs, including DPM. Emission processes modeled include running exhaust for DPM, PM2.5 and total organic compounds (TOG), running evaporative losses for TOG, and tire and brake wear and fugitive road dust for PM2.5. All PM2.5 emissions from all vehicles were used, rather than just the PM2.5 fraction from diesel powered vehicles, because all vehicle types (i.e., gasoline and diesel powered) produce PM2.5. Additionally, PM2.5 emissions from vehicle tire and brake wear and from re-entrained roadway dust were included in these emissions. DPM emissions are projected to decrease in the future and are reflected in the CT-EMFAC2017 emissions data.

Inputs to the model include region (Santa Clara County), type of road (major/collector), truck percentage for non-state highways in Santa Clara County (3.51 percent),21 traffic mix assigned by CT-EMFAC2017 for the county, year of analysis (2023 – construction start year), and season (annual).

In order to estimate TAC and PM2.5 emissions over the 30-year exposure period used for calculating the increased cancer risks for sensitive receptors at the MEI and project site, the CTEMFAC2017 model was used to develop vehicle emission factors for the year 2023 (construction start year). Emissions associated with vehicle travel depend on the year of analysis because emission control technology requirements are phased-in over time. Therefore, the earlier the year analyzed in the model, the higher the emission rates utilized by CT-EMFAC2017. Year 2023 emissions were conservatively assumed as being representative of future conditions over the time period that cancer risks are evaluated since overall vehicle emissions, and in particular diesel truck emissions, will decrease in the future.

The average daily traffic (ADT) on El Camino Real was based on AM and PM peak-hour background plus project traffic volumes for the nearby roadway provided by the project’s traffic consultant.22 The calculated ADT on El Camino Real was 30,972 vehicles. Average hourly traffic distributions for Santa Clara County roadways were developed using the EMFAC model,23 which were then applied to the ADT volumes to obtain estimated hourly traffic volumes and emissions for the roadway. For all hours of the day, other than during peak AM and PM periods, an average speed of 35 mph on El Camino Real was assumed for all vehicles based on posted speed limit 21 Bay Area Air Quality Management District, 2012, Recommended Methods for Screening and Modeling Local Risks and Hazards, Version 3.0.

22 signs on the roadway. Traffic speeds during the peak AM and PM periods were assumed to be 10 miles per hour slower (i.e., 25 mph) to account for commute congestion and the amount of access in the area.

Dispersion Modeling
Dispersion modeling of TAC and PM2.5 emissions was conducted using the EPA AERMOD air quality dispersion model, which is recommended by the BAAQMD for this type of analysis.24 TAC and PM2.5 emissions from traffic on El Camino Real within about 1,000 feet of the project site was evaluated with the model. Emissions from vehicle traffic were modeled in AERMOD using a series of volume sources along a line (line volume sources), with line segments used to represent the opposing travel lanes on each roadway. The same meteorological data used in the construction dispersion modeling were used in the roadway modeling. Other inputs to the model included road geometry, hourly traffic emissions, and receptor locations and heights. Annual TAC and PM2.5 concentrations at the project MEI for 2023 from traffic on the roadway were calculated using receptor heights of 5 feet (1.5 meters) to represent the breathing heights on the first floor of the nearby single-family residence.

Computed Cancer and Non-Cancer Health Impacts
The cancer risk, PM2.5 concentration, and HI impacts from El Camino Real on the project MEI are shown in Table 7. Figure 2 shows the roadway links used for the modeling. Details of the emission calculations, dispersion modeling, and cancer risk calculations for the receptors with the maximum cancer risk from the roadways’ traffic are provided in Attachment 5.

BAAQMD Permitted Stationary Sources
Permitted stationary sources of air pollution near the project site were identified using BAAQMD’s Permitted Stationary Sources 2018 GIS website,25 which identifies the location of nearby stationary sources and their estimated risk and hazard impacts, including emissions and adjustments to account for new OEHHA guidance. No sources within the project’s 1,000-foot influence area were identified using this tool.

Summary of Cumulative Risks at the Project MEI
Table 7 reports both the project and cumulative community risk impacts at the sensitive receptors most affected by project construction (i.e., the MEI). The project would have an exceedance with respect to community risk caused by project construction activities, since the maximum unmitigated cancer risk and annual PM2.5 concentration exceed the BAAQMD single-source thresholds. With the implementation of Mitigation Measure AQ-1 and AQ-2, the project’s cancer risk and PM2.5 concentration would be lowered to levels below the single-source thresholds. The annual HI risk values, which include unmitigated and mitigated, do not exceed the single-source 24 BAAQMD. Recommended Methods for Screening and Modeling Local Risks and Hazards.

Implement a feasible plan to reduce diesel particulate matter emissions by 87 percent such that increased cancer risk and annual PM2.5 concentrations from construction would be reduced below TAC significance levels is as follows:

1. All construction equipment larger than 25 horsepower used at the site for more than two continuous days or 20 hours total shall meet U.S. EPA Tier 4 emission standards for PM (PM10 and PM2.5), if feasible, otherwise,
a. If use of Tier 4 equipment is not available, alternatively use equipment that meets U.S. EPA emission standards for Tier 3 engines and include particulate matter emissions control equivalent to CARB verifiable diesel emission control devices that altogether achieve an 87 percent reduction in particulate matter exhaust from the Project in comparison to uncontrolled equipment; alternatively (or in combination),

2. Provide line power to the site during the early phases of construction to minimize the use of diesel-powered stationary equipment.

3. Stationary cranes shall be powered by electricity.

4. All mobile diesel construction equipment used for the project shall be registered with CARB through DOORS and have an assigned unique Equipment Identification Number (EIN). The vehicles EIN label shall be clearly visible on the equipment so the public can use DOORS, the CARB online tool, to look up the equipment type, size, and age. 326
Agenda Item # 10.
24 Alternatively, the applicant may develop another construction operations plan demonstrating that the construction equipment used on-site would achieve a reduction in construction diesel particulate matter emissions by 87 percent or greater. Elements of the plan could include a combination of some of the following measures:
• Implementation of No. 1 above to use Tier 4 or alternatively fueled equipment, • Installation of electric power lines during early construction phases to avoid use of diesel generators and compressors,
• Use of electrically-powered equipment,
• Forklifts and aerial lifts used for exterior and interior building construction shall be electric or propane/natural gas powered,
• Change in construction build-out plans to lengthen phases, and • Application of different building methods that result in less diesel equipment usage.

Such a construction operations plan would be subject to review by an air quality expert and approved by the City prior to construction.

Effectiveness of Mitigation Measure AQ-1 and AQ-2
CalEEMod was used to compute emissions associated with this mitigation measure assuming that all equipment met U.S. EPA Tier 4 interim engines standards, electric cranes, and enhanced BAAQMD best management practices for construction were included. With these measures implemented, the project’s construction cancer risk levels (assuming infant exposure) would be reduced by 91 percent to 6.74 chances per million and PM2.5 concentrations would be reduced by 83 percent to 0.27 µg/m3
. A plan that reduces DPM emissions by 87 percent would reduce cancer risk to about 9.38 chances per million. As a result, the project’s construction risk impacts would be reduced to levels below the BAAQMD single-source threshold.

Non-CEQA: On-Site Community Risk Assessment for TAC Sources - New Project Residences
The City’s El Camino Real Precise Plan Mitigation Measure AIR-2 requires new residential/sensitive receptors projects within 500 feet of El Camino Real to conduct an evaluation of potential health risk exposure for the new sensitive receptors and incorporate effective mitigation into project designs to avoid significant risks to health and safety required when new residential uses are proposed near existing sources of TACs. BAAQMD’s recommended thresholds for health risks and hazards, shown in Table 1, are used to evaluate on-site exposure for new residents. A health risk assessment was completed to determine the impacts existing TAC sources would have on the new proposed sensitive receptors (residents) that that project would introduce. The same TAC sources identified above were used in this health risk assessment.26 Figure 3 shows the on-site sensitive receptors in relation to the nearby TAC sources. All on-site community task results are listed in Table 8. Attachment 5 includes the dispersion modeling and risk calculations for TAC source impacts upon the proposed on-site sensitive receptors. 26 The extent this analysis considers existing air quality issues in relation to the impact on future residents of the Project, it does so for informational purposes only pursuant to the judicial decisions in CBIA v. BAAQMD (2015) 62 Cal.4th 369, 386 and Ballona Wetlands Land Trust v. City of Los Angeles (2011) 201 Cal.App.4th 455, 473, which confirm that the impacts of the existing environment on a project are excluded from CEQA. 327

25 Local Roadways – El Camino Real
The roadway analysis for the project residents was conducted in the same manner as described above for the off-site MEI. However, year 2025 (operational year) emission factors were conservatively assumed as being representative of future conditions, instead of 2023 (construction start year). An analysis based on 2025 resulted in an increase of ADT on El Camino Real to 31,580 vehicles. On-site receptors were placed throughout the project area and were spaced every 20 feet (6 meters). Project residences would be located on the second floor and higher of the proposed new building. Roadway impacts were modeled at receptor heights of 22 feet (6.6 meters) and 32 feet (9.9 meters) representing sensitive receptors on the second and third floors (first and second residential levels) of the future residential building based on provided project plans. Project sensitive receptors higher than the third floor would have roadway impacts less than those on the third floor. The portions of El Camino Real included in the modeling are shown in Figure 3 along with the on-site receptor locations where impacts were modeled.

Maximum increased cancer risks were calculated for the residents at the project site using the maximum modeled TAC concentrations. A 30-year exposure period was used in calculating cancer risks assuming the residents would include third trimester pregnancy and infants/children and were assumed to be in the new buildings for 24 hours per day for 350 days per year. The highest impacts from El Camino Real occurred at a second-floor (first residential level) receptor in the northeast corner of the building closest to the roadway. Cancer risks associated with the roadway are greatest closest to the roadway and decrease with distance from the road. The roadway community risk impacts at the project site are shown in Table 8. Details of the emission calculations, dispersion modeling, and cancer risk calculations are contained in Attachment 5.

Stationary Sources
The stationary source screening analysis for the new project sensitive receptors was conducted in the same manner as described above for the construction MEI. No sources were located within the project’s 1000-foot influence area.

Cumulative Community Health Risk at Project Site
Community risk impacts from the combined sources upon the project site are reported in Table 8.

The TAC sources are compared against the BAAQMD single-source threshold and then combined and compared against the BAAQMD cumulative-source threshold. As shown, the cancer risk, PM2.5 concentration, and HI from the nearby sources do not exceed their single-source or cumulative-source thresholds.

27 GREENHOUSE GAS EMISSIONS
Setting
Gases that trap heat in the atmosphere, GHGs, regulate the earth’s temperature. This phenomenon, known as the greenhouse effect, is responsible for maintaining a habitable climate. The most common GHGs are carbon dioxide (CO2) and water vapor but there are also several others, most importantly methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6). These are released into the earth’s atmosphere through a variety of natural processes and human activities. Sources of GHGs are generally as follows:
 CO2, CH4, and N2O are byproducts of fossil fuel combustion.  N2O is associated with agricultural operations such as fertilization of crops.  CH4 is commonly created by off-gassing from agricultural practices (e.g., keeping livestock) and landfill operations.
 Chlorofluorocarbons (CFCs) were widely used as refrigerants, propellants, and cleaning solvents but their production has been stopped by international treaty.  HFCs are now used as a substitute for CFCs in refrigeration and cooling.  PFCs and sulfur hexafluoride emissions are commonly created by industries such as aluminum production and semi-conductor manufacturing.

Each GHG has its own potency and effect upon the earth’s energy balance. This is expressed in terms of a global warming potential (GWP), with CO2 being assigned a value of 1 and sulfur hexafluoride being several orders of magnitude stronger. In GHG emission inventories, the weight of each gas is multiplied by its GWP and is measured in units of CO2 equivalents (CO2e).

An expanding body of scientific research supports the theory that global climate change is currently affecting changes in weather patterns, average sea level, ocean acidification, chemical reaction rates, and precipitation rates, and that it will increasingly do so in the future. The climate and several naturally occurring resources within California are adversely affected by the global warming trend. Increased precipitation and sea level rise will increase coastal flooding, saltwater intrusion, and degradation of wetlands. Mass migration and/or loss of plant and animal species could also occur. Potential effects of global climate change that could adversely affect human health include more extreme heat waves and heat-related stress; an increase in climate-sensitive diseases; more frequent and intense natural disasters such as flooding, hurricanes and drought; and increased levels of air pollution.

Recent Regulatory Actions for GHG Emissions
Executive Order S-3-05 – California GHG Reduction Targets Executive Order (EO) S-3-05 was signed by Governor Arnold Schwarzenegger in 2005 to set GHG emission reduction targets for California. The three targets established by this EO are as follows:
(1) reduce California’s GHG emissions to 2000 levels by 2010, (2) reduce California’s GHG emissions to 1990 levels by 2020, and (3) reduce California’s GHG emissions by 80 percent below 1990 levels by 2050.
330
Agenda Item # 10.
28 Assembly Bill 32 – California Global Warming Solutions Act (2006) Assembly Bill (AB) 32, the Global Warming Solutions Act of 2006, codified the State’s GHG emissions target by directing CARB to reduce the State’s global warming emissions to 1990 levels by 2020. AB 32 was signed and passed into law by Governor Schwarzenegger on September 27, 2006. Since that time, the CARB, CEC, California Public Utilities Commission (CPUC), and Building Standards Commission have all been developing regulations that will help meet the goals of AB 32 and Executive Order S-3-05, which has a target of reducing GHG emissions 80 percent below 1990 levels.

A Scoping Plan for AB 32 was adopted by CARB in December 2008. It contains the State’s main strategies to reduce GHGs from business-as-usual emissions projected in 2020 back down to 1990 levels. Business-as-usual (BAU) is the projected emissions in 2020, including increases in emissions caused by growth, without any GHG reduction measures. The Scoping Plan has a range of GHG reduction actions, including direct regulations, alternative compliance mechanisms, monetary and non-monetary incentives, voluntary actions, and market-based mechanisms such as a cap-and-trade system.

As directed by AB 32, CARB has also approved a statewide GHG emissions limit. On December 6, 2007, CARB staff resolved an amount of 427 million metric tons (MMT) of CO2e as the total statewide GHG 1990 emissions level and 2020 emissions limit. The limit is a cumulative statewide limit, not a sector- or facility-specific limit. CARB updated the future 2020 BAU annual emissions forecast, in light of the economic downturn, to 545 MMT of CO2e. Two GHG emissions reduction measures currently enacted that were not previously included in the 2008 Scoping Plan baseline inventory were included, further reducing the baseline inventory to 507 MMT of CO2e. Thus, an estimated reduction of 80 MMT of CO2e is necessary to reduce statewide emissions to meet the AB 32 target by 2020.

Executive Order B-30-15 & Senate Bill 32 GHG Reduction Targets – 2030 GHG Reduction Target In April 2015, Governor Brown signed EO B-30-15, which extended the goals of AB 32, setting a greenhouse gas emissions target at 40 percent of 1990 levels by 2030. On September 8, 2016, Governor Brown signed Senate Bill (SB) 32, which legislatively established the GHG reduction target of 40 percent of 1990 levels by 2030. In November 2017, CARB issued California’s 2017 Climate Change Scoping Plan.
27 While the State is on track to exceed the AB 32 scoping plan 2020 targets, this plan is an update to reflect the enacted SB 32 reduction target.

SB 32 was passed in 2016, which codified a 2030 GHG emissions reduction target of 40 percent below 1990 levels. CARB is currently working on a second update to the Scoping Plan to reflect the 2030 target set by Executive Order B-30-15 and codified by SB 32. The proposed Scoping Plan Update was published on January 20, 2017 as directed by SB 32 companion legislation AB 197. The mid-term 2030 target is considered critical by CARB on the path to obtaining an even deeper GHG emissions target of 80 percent below 1990 levels by 2050, as directed in Executive 27 California Air Resource Board, 2017. California’s 2017 Climate Change Scoping Plan: The Strategy for Achieving California’s 2030 Greenhouse Gas Targets. November. Web:

Agenda Item # 10.
29 Order S-3-05. The Scoping Plan outlines the suite of policy measures, regulations, planning efforts, and investments in clean technologies and infrastructure, providing a blueprint to continue driving down GHG emissions and obtain the statewide goals.

The new Scoping Plan establishes a strategy that will reduce GHG emissions in California to meet the 2030 target (note that the AB 32 Scoping Plan only addressed 2020 targets and a long-term goal). Key features of this plan are:
 Cap and Trade program places a firm limit on 80 percent of the State’s emissions;  Achieving a 50-percent Renewable Portfolio Standard by 2030 (currently at about 29 percent statewide);
 Increase energy efficiency in existing buildings;
 Develop fuels with an 18-percent reduction in carbon intensity;  Develop more high-density, transit-oriented housing;
 Develop walkable and bikeable communities;
 Greatly increase the number of electric vehicles on the road and reduce oil demand in half;  Increase zero-emissions transit so that 100 percent of new buses are zero emissions;  Reduce freight-related emissions by transitioning to zero emissions where feasible and near-zero emissions with renewable fuels everywhere else; and  Reduce “super pollutants” by reducing methane and hydrofluorocarbons or HFCs by 40 percent.

In the updated Scoping Plan, CARB recommends statewide targets of no more than 6 metric tons (MT) CO2e per capita (statewide) by 2030 and no more than 2 metric tons CO2e per capita by 2050. The statewide per capita targets account for all emissions sectors in the State, statewide population forecasts, and the statewide reductions necessary to achieve the 2030 statewide target under SB 32 and the longer-term State emissions reduction goal of 80 percent below 1990 levels by 2050.

Executive Order B-55-18 – Carbon Neutrality
In 2018, a new statewide goal was established to achieve carbon neutrality as soon as possible, but no later than 2045, and to maintain net negative emissions thereafter. CARB and other relevant state agencies are tasked with establishing sequestration targets and create policies/programs that would meet this goal.

Senate Bill 375 – California's Regional Transportation and Land Use Planning Efforts (2008) California enacted legislation (SB 375) to expand the efforts of AB 32 by controlling indirect GHG emissions caused by urban sprawl. SB 375 provides incentives for local governments and applicants to implement new conscientiously planned growth patterns. This includes incentives for creating attractive, walkable, and sustainable communities and revitalizing existing communities.

The legislation also allows applicants to bypass certain environmental reviews under CEQA if they build projects consistent with the new sustainable community strategies. Development of more alternative transportation options that would reduce vehicle trips and miles traveled, along with traffic congestion, would be encouraged. SB 375 enhances CARB’s ability to reach the AB 32 332
Agenda Item # 10.
30 goals by directing the agency in developing regional GHG emission reduction targets to be achieved from the transportation sector for 2020 and 2035. CARB works with the metropolitan planning organizations (e.g. Association of Bay Area Governments [ABAG] and Metropolitan Transportation Commission [MTC]) to align their regional transportation, housing, and land use plans to reduce vehicle miles traveled and demonstrate the region's ability to attain its GHG reduction targets. A similar process is used to reduce transportation emissions of ozone precursor pollutants in the Bay Area.

Senate Bill 350 - Renewable Portfolio Standards
In September 2015, the California Legislature passed SB 350, which increases the states Renewables Portfolio Standard (RPS) for content of electrical generation from the 33 percent target for 2020 to a 50 percent renewables target by 2030.

Senate Bill 100 – Current Renewable Portfolio Standards In September 2018, SB 100 was signed by Governor Brown to revise California’s RPS program goals, furthering California’s focus on using renewable energy and carbon-free power sources for its energy needs. The bill would require all California utilities to supply a specific percentage of their retail sales from renewable resources by certain target years. By December 31, 2024, 44 percent of the retails sales would need to be from renewable energy sources, by December 31, 2026 the target would be 40 percent, by December 31, 2017 the target would be 52 percent, and by December 31, 2030 the target would be 60 percent. By December 31, 2045, all California utilities would be required to supply retail electricity that is 100 percent carbon-free and sourced from eligible renewable energy resource to all California end-use customers.

California Building Standards Code – Title 24 Part 11 & Part 6 The California Green Building Standards Code (CALGreen Code) is part of the California Building Standards Code under Title 24, Part 11.28 The CALGreen Code encourages sustainable construction standards that involve planning/design, energy efficiency, water efficiency resource efficiency, and environmental quality. These green building standard codes are mandatory statewide and are applicable to residential and non-residential developments. The most recent CALGreen Code (2019 California Building Standard Code) was effective as of January 1, 2020.

The California Building Energy Efficiency Standards (California Energy Code) is under Title 24, Part 6 and is overseen by the California Energy Commission (CEC). This code includes design requirements to conserve energy in new residential and non-residential developments, while being cost effective for homeowners. This Energy Code is enforced and verified by cities during the planning and building permit process. The current energy efficiency standards (2019 Energy Code) replaced the 2016 Energy Code as of January 1,2020. Under the 2019 standards, single-family homes are predicted to be 53 percent more efficient than homes built under the 2016 standard due more stringent energy-efficiency standards and mandatory installation of solar photovoltaic 28 See: https://www.dgs.ca.gov/BSC/Resources/Page-Content/Building-Standards-Commission-Resources-ListFolder/CALGreen#:~:text=CALGreen%20is%20the%20first%2Din,to%201990%20levels%20by%202020. 333

31 systems. For nonresidential developments, it is predicted that these buildings will use 30 percent less energy due to lightening upgrades.29
CEC studies have identified the most aggressive electrification scenario as putting the building sector on track to reach the carbon neutrality goal by 2045.30 Installing new natural gas infrastructure in new buildings will interfere with this goal. To meet the State’s goal, communities have been adopting “Reach” codes that prohibit natural gas connections in new and remodeled buildings.

Requirements for electric vehicle (EV) charging infrastructure are set forth in Title 24 of the California Code of Regulations and are regularly updated on a 3-year cycle. The CALGreen standards consist of a set of mandatory standards required for new development, as well as two more voluntary standards known as Tier 1 and Tier 2. The CalGreen standards have recently been updated (2022 version) to require deployment of additional EV chargers in various building types, including multifamily residential and nonresidential land uses. They include requirements for both EV capable parking spaces and the installation of Level 2 EV supply equipment for multifamily residential and nonresidential buildings. The 2022 CALGreen standards include requirements for both EV readiness and the actual installation of EV chargers. The 2022 CALGreen standards include both mandatory requirements and more aggressive voluntary Tier 1 and Tier 2 provisions.

Providing EV charging infrastructure that meets current CALGreen requirements will not be sufficient to power the anticipated more extensive level of EV penetration in the future that is needed to meet SB 30 climate goals.

SB 743 Transportation Impacts

Senate Bill 743 required lead agencies to abandon the old “level of service” metric for evaluating a project’s transportation impacts, which was based solely on the amount of delay experienced by motor vehicles. In response, the Governor’s Office of Planning and Research (OPR) developed a VMT metric that considered other factors such as reducing GHG emissions and developing multimodal transportation31. A VMT-per-capita metric was adopted into the CEQA Guidelines Section 15064.3 in November 2017. Given current baseline per-capita VMT levels computed by CARB in the 2030 Scoping Plan of 22.24 miles per day for light-duty vehicles and 24.61 miles per day for all vehicle types, the reductions needed to achieve the 2050 climate goal are 16.8 percent for light-duty vehicles and 14.3 percent for all vehicle types combined. Based on this analysis (as well as other factors), OPR recommended using a 15-percent reduction in per capita VMT as an appropriate threshold of significance for evaluating transportation impacts.

32 Federal and Statewide GHG Emissions
The U.S. EPA reported that in 2018, total gross nationwide GHG emissions were 6,676.6 million metric tons (MMT) carbon dioxide equivalent (CO2e).32 These emissions were lower than peak levels of 7,416 MMT that were emitted in 2007. CARB updates the statewide GHG emission inventory on an annual basis where the latest inventory includes 2000 through 2017 emissions.33 In 2017, GHG emissions from statewide emitting activities were 424 MMT. The 2017 emissions have decreased by 14 percent since peak levels in 2004 and are 7 MMT below the 1990 emissions level and the State’s 2020 GHG limit. Per capita GHG emissions in California have dropped from a 2001 peak of 14.1 MT per person to 10.7 MT per person in 2017. The most recent Bay Area emission inventory was computed for the year 2011.34 The Bay Area GHG emission were 87 MMT. As a point of comparison, statewide emissions were about 444 MMT in 2011 Los Altos Climate Action Plan and Climate Action and Adaptation Plan The City of Los Altos adopted a Climate Action Plan (CAP)35 in 2013 that included a goal to improve communitywide emissions efficiency by 15 percent over 2005 levels by 2020. In 2022 the City of Los Altos developed a Climate Action and Adaptation Plan (CAAP),36 which assesses the impacts of Los Altos on the climate, how Los Altos can reduce its impact on the climate and how Los Altos can adapt to the changing climate. The CAAP proposes a strategic roadmap of strategies goals, and actions to help reduce GHG emissions in order to reach a goal of Carbon Neutrality by 2035.

To implement and monitor the success of the CAP, the City of Los Altos requires all new projects to comply with their CAP checklist. This document helps city planners ensure that the new project would be consistent with the City’s GHG reduction goals. A project must incorporate all the Best management Practices (BMPs) identified in the checklist. This project’s CAP checklist is included in Attachment 6. However, the CAP and CAAP are not qualified GHG reductions plan and do not have specific metric ton or service population GHG threshold for project-level construction or operation. Therefore, the BAAQMD’s CEQA Air Quality Guideline’s thresholds are used.

BAAQMD GHG Significance Thresholds
The BAAQMD’s CEQA Air Quality Guidelines do not use quantified thresholds for projects that are in a jurisdiction with a qualified GHG reductions plan (i.e., a Climate Action Plan). The plan 32 United States Environmental Protection Agency, 2020. Inventory of U.S. Greenhouse Gas Emissions and Sinks 1990-2018. April.

33 has to address emissions associated with the period that the project would operate (e.g., beyond year 2020). For quantified emissions, the guidelines recommended a GHG threshold of 1,100 metric tons or 4.6 metric tons (MT) per capita. These thresholds were developed based on meeting the 2020 GHG targets set in the scoping plan that addressed AB 32. Development of the project would occur beyond 2020, so a threshold that addresses a future target is appropriate.

Although BAAQMD has not published a quantified threshold for 2030 yet, this assessment uses a “Substantial Progress” efficiency metric of 2.8 MT CO2e/year/service population and a bright-line threshold of 660 MT CO2e/year based on the GHG reduction goals of EO B-30-15. The service population metric of 2.8 is calculated for 2030 based on the 1990 inventory and the projected 2030 statewide population and employment levels. 37 The 2030 bright-line threshold is a 40 percent reduction of the 2020 1,100 MT CO2e/year threshold. Evidence published by the State indicates the AB 32 goal of reducing statewide GHG emissions to 1990 levels was met prior to 2020. Current State plans are to further reduce emissions to 40% below 1990 levels by 2030. Assuming statewide emissions are at 1990 levels or lower in 2020, it would be logical to reduce the BAAQMDrecommended threshold for meeting the AB 32 threshold by 40% to develop a threshold for 2030.

Impact GHG-1: Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment?
GHG emissions associated with development of the proposed project would occur over the shortterm from construction activities, consisting primarily of emissions from equipment exhaust and worker and vendor trips. There would also be long-term operational emissions associated with vehicular traffic within the project vicinity, energy and water usage, and solid waste disposal.

Emissions for the proposed project are discussed below and were analyzed using the methodology recommended in the BAAQMD CEQA Air Quality Guidelines.

CalEEMod Modeling
CalEEMod was used to predict GHG emissions from operation of the site assuming full build-out of the project. The project land use types and size and other project-specific information were input to the model, as described above within the operational period emissions. CalEEMod output is included in Attachment 2.

Service Population Emissions
The project service population efficiency rate is based on the number of future residents. For this project, the number of future residents was estimated by multiplying the total number of units (i.e., 90 units) by the persons per household rate for the City of Los Altos found in the California Department of Finance Population and Housing Estimate report.38 Using the 2.72-person per 37 Bay Area Air Quality Management District, 2016.

Agenda Item # 10.
34 household 2020 rate, the number of future residents was estimated to be 245 residents. This total service population was used to calculate the per capita emissions.

Construction Emissions
GHG emissions associated with construction were computed to be 977 MT of CO2e for the total construction period. These are the emissions from on-site operation of construction equipment, vendor and hauling truck trips, and worker trips. Neither the City nor BAAQMD have an adopted threshold of significance for construction-related GHG emissions, though BAAQMD recommends quantifying emissions and disclosing that GHG emissions would occur during construction.

BAAQMD also encourages the incorporation of best management practices to reduce GHG emissions during construction where feasible and applicable.

Operational Emissions
The CalEEMod model, along with the project vehicle trip generation rates, was used to estimate daily emissions associated with operation of the fully developed site under the proposed project.

As shown in Table 9, the net annual emissions resulting from operation of the proposed project are predicted to be 241 MT of CO2e in 2025 and 214 MT of CO2e in 2030. The service population emission for the year 2025 and 2030 are predicted to be 1.4 and 1.3 MT/CO2e/year/service population, respectively.

To be considered an exceedance, the project must exceed both the GHG significance threshold in metric tons per year and the service population significance threshold in the future year of 2030.

As shown in Table 8, the project would not exceed the annual emissions bright-line threshold of 660 MT CO2e/year in 2030 and would not exceed the per service population threshold of 2.8 MT of CO2e/year/service population in 2030. In addition, the project completed the City’s CAP checklist for new developments included in Attachment 6. Therefore, the project would not exceed thresholds for GHG emissions.

35 Impact GHG-2: Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases?
The proposed building would be constructed in conformance with CALGreen and the Title 24 Building Code, which requires high-efficiency water fixtures, water-efficient irrigation systems, and compliance with current energy efficacy standards. To avoid interference with statewide GHG reduction measures identified in CARB’s Scoping Plan and SB 100 goals, the Project should include the following measures:

1. Avoid construction of new natural gas connections for the residential building,  Conforms – compliance with City Reach Code would prohibit natural gas infrastructure in new buildings.

2. Avoid wasteful or inefficient use of electricity,
 Conforms – would meet CALGreen Building Standards Code requirements that are considered to be energy efficient.

3. Include electric vehicle charging infrastructure that meets current Building Code CALGreen Tier 2 compliance, and
 Conforms – project would provide electric vehicle charging infrastructure.

4. Reduce VMT per capita by 15 percent over baseline conditions.  Unknown – check with project traffic analysis.

Attachment 1: Health Risk Calculation Methodology
A health risk assessment (HRA) for exposure to Toxic Air Contaminates (TACs) requires the application of a risk characterization model to the results from the air dispersion model to estimate potential health risk at each sensitive receptor location. The State of California Office of Environmental Health Hazard Assessment (OEHHA) and California Air Resources Board (CARB) develop recommended methods for conducting health risk assessments. The most recent OEHHA risk assessment guidelines were published in February of 2015.39 These guidelines incorporate substantial changes designed to provide for enhanced protection of children, as required by State law, compared to previous published risk assessment guidelines. CARB has provided additional guidance on implementing OEHHA’s recommended methods.40 This HRA used the 2015 OEHHA risk assessment guidelines and CARB guidance. The BAAQMD has adopted recommended procedures for applying the newest OEHHA guidelines as part of Regulation 2, Rule 5: New Source Review of Toxic Air Contaminants.41 Exposure parameters from the OEHHA guidelines and the recent BAAQMD HRA Guidelines were used in this evaluation.

Cancer Risk
Potential increased cancer risk from inhalation of TACs is calculated based on the TAC concentration over the period of exposure, inhalation dose, the TAC cancer potency factor, and an age sensitivity factor to reflect the greater sensitivity of infants and children to cancer causing TACs. The inhalation dose depends on a person’s breathing rate, exposure time and frequency and duration of exposure. These parameters vary depending on the age, or age range, of the persons being exposed and whether the exposure is considered to occur at a residential location or other sensitive receptor location.

The current OEHHA guidance recommends that cancer risk be calculated by age groups to account for different breathing rates and sensitivity to TACs. Specifically, they recommend evaluating risks for the third trimester of pregnancy to age zero, ages zero to less than two (infant exposure), ages two to less than 16 (child exposure), and ages 16 to 70 (adult exposure). Age sensitivity factors (ASFs) associated with the different types of exposure are an ASF of 10 for the third trimester and infant exposures, an ASF of 3 for a child exposure, and an ASF of 1 for an adult exposure. Also associated with each exposure type are different breathing rates, expressed as liters per kilogram of body weight per day (L/kg-day) or liters per kilogram of body weight per 8-hour period for the case of worker or school child exposures. As recommended by the BAAQMD for residential exposures, 95th percentile breathing rates are used for the third trimester and infant exposures, and 80th percentile breathing rates for child and adult exposures. For children at schools and daycare facilities, BAAQMD recommends using the 95th percentile 8-hour breathing rates.

Additionally, CARB and the BAAQMD recommend the use of a residential exposure duration of 39 OEHHA, 2015.

30 years for sources with long-term emissions (e.g., roadways). For workers, assumed to be adults, a 25-year exposure period is recommended by the BAAQMD. For school children a 9-year exposure period is recommended by the BAAQMD.

Under previous OEHHA and BAAQMD HRA guidance, residential receptors are assumed to be at their home 24 hours a day, or 100 percent of the time. In the 2015 Risk Assessment Guidance, OEHHA includes adjustments to exposure duration to account for the fraction of time at home (FAH), which can be less than 100 percent of the time, based on updated population and activity statistics. The FAH factors are age-specific and are: 0.85 for third trimester of pregnancy to less than 2 years old, 0.72 for ages 2 to less than 16 years, and 0.73 for ages 16 to 70 years. Use of the FAH factors is allowed by the BAAQMD if there are no schools in the project vicinity have a cancer risk of one in a million or greater assuming 100 percent exposure (FAH = 1.0).

Functionally, cancer risk is calculated using the following parameters and formulas:

Cancer Risk (per million) = CPF x Inhalation Dose x ASF x ED/AT x FAH x 106 Where:

CPF = Cancer potency factor (mg/kg-day)-1
ASF = Age sensitivity factor for specified age group
ED = Exposure duration (years)
AT = Averaging time for lifetime cancer risk (years)
FAH = Fraction of time spent at home (unitless)
Inhalation Dose = Cair x DBR* x A x (EF/365) x 10-6
Where:

Cair = concentration in air (μg/m3)
DBR = daily breathing rate (L/kg body weight-day)
8HrBR = 8-hour breathing rate (L/kg body weight-8 hours) A = Inhalation absorption factor
EF = Exposure frequency (days/year)
10-6 = Conversion factor
* An 8-hour breathing rate (8HrBR) is used for worker and school child exposures.

The health risk parameters used in this evaluation are summarized as follows:

Non-Cancer Hazards
Non-cancer health risk is usually determined by comparing the predicted level of exposure to a chemical to the level of exposure that is not expected to cause any adverse effects (reference exposure level), even to the most susceptible people. Potential non-cancer health hazards from TAC exposure are expressed in terms of a hazard index (HI), which is the ratio of the TAC concentration to a reference exposure level (REL). OEHHA has defined acceptable concentration levels for contaminants that pose non-cancer health hazards. TAC concentrations below the REL are not expected to cause adverse health impacts, even for sensitive individuals. The total HI is calculated as the sum of the HIs for each TAC evaluated and the total HI is compared to the BAAQMD significance thresholds to determine whether a significant non-cancer health impact from a project would occur.

Typically, for residential projects located near roadways with substantial TAC emissions, the primary TAC of concern with non-cancer health effects is diesel particulate matter (DPM). For DPM, the chronic inhalation REL is 5 micrograms per cubic meter (μg/m3).

Annual PM2.5 Concentrations
While not a TAC, fine particulate matter (PM2.5) has been identified by the BAAQMD as a pollutant with potential non-cancer health effects that should be included when evaluating potential community health impacts under the California Environmental Quality Act (CEQA). The thresholds of significance for PM2.5 (project level and cumulative) are in terms of an increase in the annual average concentration. When considering PM2.5 impacts, the contribution from all sources of PM2.5 emissions should be included. For projects with potential impacts from nearby local roadways, the PM2.5 impacts should include those from vehicle exhaust emissions, PM2.5 generated from vehicle tire and brake wear, and fugitive emissions from re-suspended dust on the roads.

Cancer Risk Calculation Method
Cancer Risk (per million) =CPF x Inhalation Dose x ASF x ED/AT x FAH x 1.0E6 Where: CPF = Cancer potency factor (mg/kg-day)-1
ASF = Age sensitivity factor for specified age group
ED = Exposure duration (years)
AT = Averaging time for lifetime cancer risk (years)
FAH = Fraction of time spent at home (unitless)
Inhalation Dose = Cair x DBR x A x (EF/365) x 10-6
Where: Cair = concentration in air (μg/m3)
DBR = daily breathing rate (L/kg body weight-day)
A = Inhalation absorption factor
EF = Exposure frequency (days/year)
10-6 = Conversion factor

Cancer Risk Calculation Method
Cancer Risk (per million) =CPF x Inhalation Dose x ASF x ED/AT x FAH x 1.0E6 Where: CPF = Cancer potency factor (mg/kg-day)-1
ASF = Age sensitivity factor for specified age group
ED = Exposure duration (years)
AT = Averaging time for lifetime cancer risk (years)
FAH = Fraction of time spent at home (unitless)
Inhalation Dose = Cair x DBR x A x (EF/365) x 10-6
Where: Cair = concentration in air (μg/m3)
DBR = daily breathing rate (L/kg body weight-day)
A = Inhalation absorption factor
EF = Exposure frequency (days/year)
10-6 = Conversion factor

HortScience | Bartlett Consulting ● Divisions of The F.A. Bartlett Tree Expert Company Preliminary Arborist Report
330 Distel Circle, Los Altos CA
Introduction and Overview
EAH Housing is proposing to redevelop the property located at 330 Distel Circle, in Los Altos.

The plan proposes to construct affordable housing using modern, flexible and sustainable building approaches. HortScience | Bartlett Consulting (HBC), Divisions of The F. A. Bartlett Tree Expert Co. was asked to prepare a Preliminary Arborist Report to meet the City of Los Altos’ requirements.

This report provides the following information:

1. An assessment of trees within and immediately adjacent to the project site.

2. An assessment of the impacts of constructing the proposed project on the trees.

3. Preliminary recommendations for tree preservation and removal.

4. Preliminary guidelines for tree preservation during the design, construction and maintenance phases.

Assessment Methods
Trees were assessed on July 29, 2021. All trees measuring 6” or greater in diameter, within the project area or with portions of their crowns extending into the project area, were included (per City of Los Altos Chapter 11.08, Tree Protection Regulations). The assessment procedure consisted of the following steps:

1. Identifying the tree as to species;

2. Tagging each tree with an identifying number and recording its location on a map;

3. Measuring the trunk diameter at a point 48” above grade;

4. Evaluating the health and structural condition using a scale of 1–5:
5 - A healthy, vigorous tree, reasonably free of signs and symptoms of disease, with good structure and form typical of the species.
4 - Tree with slight decline in vigor, small amount of twig dieback, minor structural defects that could be corrected.
3 - Tree with moderate vigor, moderate twig and small branch dieback, thinning of crown, poor leaf color, moderate structural defects that might be mitigated with regular care.
2 - Tree in decline, epicormic growth, extensive dieback of medium to large branches, significant structural defects that cannot be abated. 1 - Tree in severe decline, dieback of scaffold branches and/or trunk; most of foliage from epicormics; extensive structural defects that cannot be abated.

5. Rating the suitability for preservation as ”high”, “moderate” or “low”. Suitability for preservation considers the health, age and structural condition of the tree, and its potential to remain an asset to the site for years to come.

High: Trees with good health and structural stability that have the potential for longevity at the site.

Moderate: Trees with somewhat declining health and/or structural defects than can be abated with treatment. The tree will require more intense management and monitoring, and may have shorter life span than those in ‘good’ category.

Low: Tree in poor health or with significant structural defects that cannot be mitigated. Tree is expected to continue to decline, regardless of treatment. The species or individual may have characteristics that are undesirable for landscapes, and generally are unsuited for use areas.

Arborist Report – September 2021 revised February 2022
EAH Housing - 330 Distel Circle, Los Altos Page 2
HortScience | Bartlett Consulting ● Divisions of The F.A. Bartlett Tree Expert Company Description of Trees
Twenty-seven (27) trees were assessed, representing 11 species (Table 1, following page).

Eight (8) off-site trees with portions of their crowns extending onto the development site were included in the assessment (#449, 450 and 452-457). Descriptions of each tree are found in the Tree Assessment Form and locations are plotted on the Tree Assessment Plan (see Exhibits).

The site was a single-story office building, with perimeter landscaping. Vegetation at the site was primarily exotic species, with a handful of native coast live oaks and coast redwoods.

Nine (9) holly oaks made up the
backbone of the landscaping, with
#431-435 on the north side of the
building and #440, 441, 445 and 450
(off-site) on the south side of the
building. The majority of these were
young to semi-mature, with trunk
diameters from 7” to 15”. Holly oak
#433 was mature at 20” in trunk
diameter and the only holly oak in
good condition (Photo 1). Most had
not been provided sufficient space for
full development and were crowded
by adjacent trees, producing onesided crowns and leaning trunks.

Seven holly oaks were in fair
condition, #435 was in poor and #433
was in good condition.

Four evergreen pears were growing adjacent to the building, with #437 and 438 on the west side and #443 and 444 on the east side. They were semi-mature (11” to 15” in trunk diameter) and primarily in fair condition, with #443 in good condition. Most leaned as a result of competition for light and #443 and 444 had been planted in close proximity to the existing building and parking lot, displacing the adjacent asphalt by an estimated 5”.

Three coast live oaks were assessed, with #436 located in the northwest corner of the site and #449 (off-site) and 451 located to the south of the building. Coast live oak #436 was young (9” in diameter) and in fair condition. Coast live oaks #449 and 451 were both mature and in good condition.

Sweetgums #447 and 448 were growing in the planter behind the sidewalk along Distal Circle.

Sweetgum #447 was young (10” in diameter) and #448 was semi-mature at 14” in diameter. Both were in fair condition, but #447 was in decline, with a very sparse crown.

Photo 1: Looking north at holly oak
#433. This was the only holly oak on
the site that was mature (20” in
diameter) and in good condition.

HortScience | Bartlett Consulting ● Divisions of The F.A. Bartlett Tree Expert Company The remaining species were represented by the following individuals:
• Mexican fan palm #439 was growing on the west side of the building. It was mature and in excellent condition.
• African fern pine #442 was growing in the planter in front of the building, adjacent to evergreen pears #443 and 444. It was mature (22” in diameter) and in good condition.

However, it too had been planted too close to the building and parking lot and was displacing the adjacent asphalt by an estimated 5”.
• Olive #446 was multi-stemmed and growing in the landscape along the Distal Circ.

Frontage. It was in good condition, with good form and structure and a slightly sparse canopy.
• Calif. sycamore #457 was located just off-site on the west side of the property. It was mature (24” in diameter) and leaned northwest. It had been planted in a very small space and the base was growing against both the wall and curb.

Average tree condition for the site was fair, with 18 trees or 66% of the population. Eight (8) trees were in good condition (30%) and holly oak #435 was the only tree in poor condition (4%). Table 1 (previous page) provides a summary of condition by species.

The City of Los Altos protects all trees with diameters of 15” or greater located on private property. Removal of any tree with a diameter of 15” or greater requires a permit issued by the City, per Chapter 11.08 (Tree Protection Regulations). Based on this definition, 13 of the trees assessed at the 330 Distal Circ. Site qualified as Protected. All Protected trees are identified in the Tree Assessment Form (see Exhibits).

Suitability for Preservation
Before evaluating the impacts that will occur during development, it is important to consider the quality of the tree resource itself, and the potential for individual trees to function well over an extended length of time. Trees that are preserved on development sites must be carefully selected to make sure that they may survive development impacts, adapt to a new environment and perform well in the landscape.

Our goal is to identify trees that have the potential for long-term health, structural stability and longevity. For trees growing in open fields, away from areas where people and property are present, structural defects and/or poor health presents a low risk of damage or injury if they fail.

However, we must be concerned about safety in use areas. Therefore, where development encroaches into existing plantings, we must consider their structural stability as well as their potential to grow and thrive in a new environment. Where development will not occur, the normal life cycles of decline, structural failure and death should be allowed to continue.

Evaluation of suitability for preservation considers several factors:
▪ Tree health
Healthy, vigorous trees are better able to tolerate impacts such as root injury, demolition of existing structures, changes in soil grade and moisture, and soil compaction than are non-vigorous trees.
▪ Structural integrity
Trees with significant amounts of wood decay and other structural defects that cannot be corrected are likely to fail. Such trees should not be preserved in areas where damage to people or property is likely. Holly oak #435 is an examples of such a tree. 518

HortScience | Bartlett Consulting ● Divisions of The F.A. Bartlett Tree Expert Company ▪ Species response
There is a wide variation in the response of individual species to construction impacts and changes in the environment. In our experience, for example, holly oak, coast live oak and coast redwood are tolerant of site disturbance, while sweetgum is more sensitive to site disturbance.
▪ Tree age and longevity
Old trees, while having significant emotional and aesthetic appeal, have limited physiological capacity to adjust to an altered environment. Young trees are better able to generate new tissue and respond to change.
▪ Invasiveness
Species which spread across a site and displace desired vegetation are not always appropriate for retention. This is particularly true when indigenous species are displaced. The California Invasive Plant Inventory Database (http://www.cal-ipc.org/paf/) lists species identified as being invasive. Los Altos is part of the Central West Floristic Province. Olive was the only species assessed at the 330 Distal Circ. site considered to have ‘Limited’ invasiveness.

Each tree was rated for suitability for preservation based upon its age, health, structural condition and ability to safely coexist within a development environment. Table 2 provides a summary of suitability ratings. Suitability ratings for individual trees are provided in the Tree Assessment Forms (see Exhibits).

We consider trees with high suitability for preservation to be the best candidates for preservation.

We do not recommend retention of trees with low suitability for preservation in areas where people or property will be present. Retention of trees with moderate suitability for preservation depends upon the intensity of proposed site changes.

Table 2: Tree Suitability for Preservation
330 Distel Circle, Los Altos
High These are trees with good health and structural stability that have the potential for longevity at the site. Three (3) of the trees were highly suitable for preservation, including Mexican fan palm #439, olive #446 and coast live oak #451.

Moderate Trees in this category have fair health and/or structural defects that may be abated with treatment. Trees in this category require more intense management and monitoring, and may have shorter life-spans than those in the “high” category. Sixteen (16) of the trees were of moderate suitability for preservation, including 4 holly oaks, 3 evergreen pears, 2 coast live oaks, 2 Hollywood junipers, 2 coast redwoods and one each of: African fern pine, xylosma and Calif. sycamore.

Low Trees in this category are in poor health or have significant defects in structure that cannot be abated with treatment. These trees can be expected to decline regardless of management. Eight (8) trees were of low suitability for preservation, including 5 holly oaks, sweetgums #447 and 448 and evergreen pear #437.

HortScience | Bartlett Consulting ● Divisions of The F.A. Bartlett Tree Expert Company Preliminary Evaluation of Impacts and Recommendations
Appropriate tree retention develops a practical match between the location and intensity of construction activities and the quality and health of trees. The Tree Assessment was the reference point for tree condition and quality. Impacts from construction were evaluated using the Preliminary Grading & Utility Plan C3.0, prepared by BKF Engineers dated October 18, 2021.

The plans were preliminary however, included utilities and accurate trunk locations. However, a final assessment is based on final plans.

The plan proposes to redevelop the site into 90 residential units in 5-stories, with ground floor amenities and vertical/mechanical lift parking. Site amenities would include a courtyard, community room, laundry facility and lounge. The main entry would be located along the northeast property boundary, providing access to parking in the north corner of the building. A utility box will be located at the south corner of the site.

Impacts from construction were estimated for each tree. Based on my review of the plans, all of the on-site trees will be removed to accommodate development plan, including eight Protected trees (#432, 433, 438-440, 442, 443, and 451). Table 3 (following page) provides the recommendations for each tree along with a description of the impacts and their Protected status.

Eight trees have been identified for preservation, all of which are off-site. Five of the trees identified for preservation qualified as Protected. Preservation of trees is predicated on following the Tree Preservation Guidelines provided on the following page.

Some amount of root and canopy pruning of off-site trees may be required for construction clearance. Recommendations for Tree Protection Zones are provided in the Tree Preservation Guidelines (following page).

Preliminary Tree Preservation Guidelines
The goal of tree preservation is not merely tree survival during development but maintenance of tree health and beauty for many years. Trees retained on sites that are either subject to extensive injury during construction or are inadequately maintained become a liability rather than an asset. The response of individual trees will depend on the amount of excavation and grading, the care with which demolition is undertaken, and the construction methods.

The following recommendations will help reduce impacts to trees from development and maintain and improve their health and vitality through the clearing, grading and construction phases.

Design recommendations

1. Any plan affecting trees should be reviewed by the Consulting Arborist with regard to tree impacts. These include, but are not limited to, improvement plans, utility and drainage plans, grading plans, landscape and irrigation plans and demolition plans.

2. A TREE PROTECTION ZONE must be established for trees to be preserved, in which no disturbance is permitted. No trenching, excavation, construction or storage of materials shall occur within that zone. No underground services including utilities, sub-drains, water or sewer shall be placed in the Tree Protection Zone. Spoil from trench, footing, utility or other excavation shall not be placed within the Tree Protection Zone, either temporarily or permanently. For design purposes, TREE PROTECTION ZONES for trees identified for preservation should be established at the dripline in all directions. As plans are refined, more specific TREE PROTECTION ZONES will be developed.

3. Tree Preservation Guidelines prepared by the Consulting Arborist should be included on all plans.

4. No underground services including utilities, sub-drains, water or sewer shall be placed in the TREE PROTECTION ZONE. To minimize impacts to trees, locate underground services to provide as much room as possible from trees identified for preservation.

5. Any herbicides placed under paving materials must be safe for use around trees and labeled for that use.

6. Irrigation systems must be designed to avoid trenching within the TREE PROTECTION ZONE.

7. Do not apply lime to soil for stabilization within 25’ of trees to be preserved. Lime is toxic to tree roots.

Pre-construction treatments and recommendations

1. The demolition contractor and construction superintendent shall meet with the Consulting Arborist before beginning work to discuss work procedures and tree protection. 521
Agenda Item # 10.

Arborist Report – September 2021 revised February 2022
EAH Housing - 330 Distel Circle, Los Altos Page 8
HortScience | Bartlett Consulting ● Divisions of The F.A. Bartlett Tree Expert Company

2. Fence all trees to be retained to completely enclose the TREE PROTECTION ZONE prior to demolition, grubbing or grading. Fences shall be 6’ chain link anchored firmly in the ground or on stanchions. Fences are to remain until all grading and construction is completed. Place weather proof signs, 2’ x 2’, on the fencing that read “Tree Protection Zone Keep Out” (eg. one sign for each of the four compass points).

3. Where possible, cap and abandon all existing underground utilities within the TPZ in place. Removal of utility boxes by hand is acceptable but no trenching should be performed within the TPZ in an effort to remove utilities, irrigation lines, etc.

4. Tree(s) to be removed that have branches extending into the canopy of tree(s) to remain must be removed by a qualified arborist and not by demolition or construction contractors. The qualified arborist shall remove the tree in a manner that causes no damage to the tree(s) and understory to remain. Stumps shall be ground below grade.

5. Any brush clearing required within the TREE PROTECTION ZONE shall be accomplished with hand-operated equipment.

6. Any work within the TREE PROTECTION ZONE shall be approved and monitored by the Consulting Arborist.

7. Prune trees to be preserved to provide adequate clearance and correct any existing defects in structure. All pruning shall be completed by a Certified Arborist or Tree Worker and adhere to the latest edition of the ANSI Z133 and A300 standards as well as the Best Management Practices -- Tree Pruning published by the International Society of Arboriculture.

8. All tree work shall comply with the Migratory Bird Treaty Act as well as California Fish and Wildlife code 3503-3513 to not disturb nesting birds. To the extent feasible tree pruning and removal should be scheduled outside of the breeding season. Breeding bird surveys should be conducted prior to tree work. Qualified biologists should be involved in establishing work buffers for active nests.

9. Apply and maintain 4-6” of wood chip mulch within the TREE PROTECTION ZONE.

Recommendations for tree protection during construction

1. Prior to beginning work, all contractors working in the vicinity of trees to be preserved are required to meet with the Consulting Arborist at the site to review all work procedures, access routes, storage areas and tree protection measures.

2. If injury should occur to any tree during construction, it should be evaluated as soon as possible by the Consulting Arborist so that appropriate treatments can be applied.

3. Fences have been erected to protect trees to be preserved. Fences define a specific TREE PROTECTION ZONE for each tree or group of trees. Fences are to remain until all site work has been completed. Fences may not be relocated or removed without permission of the Consulting Arborist.

4. Construction trailers, traffic and storage areas must remain outside fenced areas at all times.

5. Prior to grading, pad preparation, excavation for foundations/footings/walls, trenching, trees may require root pruning outside the TREE PROTECTION ZONE by cutting all roots cleanly to the depth of the excavation. Roots shall be cut by manually digging a trench 522
Agenda Item # 10.

Arborist Report – September 2021 revised February 2022
EAH Housing - 330 Distel Circle, Los Altos Page 9
HortScience | Bartlett Consulting ● Divisions of The F.A. Bartlett Tree Expert Company and cutting exposed roots with a saw, with a vibrating knife, rock saw, narrow trencher with sharp blades, or other approved root pruning equipment. The Consulting Arborist will identify where root pruning is required and monitor all root pruning activities

6. Any roots damaged during grading or construction shall be exposed to sound tissue and cut cleanly with a saw.

7. All underground utilities, drain lines or irrigation lines shall be routed outside the TREE PROTECTION ZONE. If lines must traverse through the protection area, they shall be tunneled or bored under the tree as directed by the Consulting Arborist.

8. No materials, equipment, spoil, waste or wash-out water may be deposited, stored, or parked within the TREE PROTECTION ZONE (fenced area).

9. Any additional tree pruning needed for clearance during construction must be performed by a qualified arborist and not by construction personnel.

Maintenance of impacted trees
Trees preserved at the 330 Distel Circ. site may experience a physical environment different from that pre-development. As a result, tree health and structural stability should be monitored.

Occasional pruning, fertilization, mulch, pest management, replanting and irrigation may be required. In addition, provisions for monitoring both tree health and structural stability following construction must be made a priority. As trees age, the likelihood of failure of branches or entire trees increases. Therefore, annual inspection for structural condition is recommended.
