SUMMARY
The City Council will consider an appeal of the Planning Commission’s decision to deny the adoption Mitigated Negative Declaration (MND) No. 951, the Mitigation Monitoring and Reporting Program (MMRP) and Conditional Use Permit (CUP) Case No. 21-008; a request to develop a gated 60-unit attached residential condominium development on a 2.45-acre Successor Agency owned lot located at 930 W. Compton Blvd

BACKGROUND
On May 11, 2022, the Planning Commission held a public hearing on the above-listed requests.

After due consideration, the Planning Commission did not adopt Mitigated Negative Declaration (MND) No. 951 & Mitigation Monitoring and Reporting Program (MMRP) and denied Conditional Use Permit (CUP) Case No. 21-008. As a result, City Ventures (the applicant) has appealed that decision to City Council. Planning Commission appeals must be considered at a public hearing in accordance with Section 30-26 of the Compton Municipal Code. The project also is requesting approval of a General Plan Amendment, Change of Zone and Tentative Tract Map.

PROJECT DESCRIPTION
The City Ventures Company is requesting the approval of the above applications to develop a gated 60-unit three-story condominium community on a vacant 2.45-acre successor agency owned property located at 930 W. Compton Blvd. (southeast corner of Compton Blvd. and Kemp Avenue).

There will three types of units with three to four bedrooms, 2.5 to 4 bathrooms and an attached twocar garage in either a standard side-by-side format or tandem format. Two common open space areas are proposed with amenities along with 15 guest parking spaces and 10 affordable units. This project will develop the entire block bordered by Compton Blvd., Kemp Ave., 151st Street and Dwight Ave.

1. Staff Report – City Council Appeal of CUP Case No. 21-008 and MND No. 951 June 28, 2022

STATEMENT OF THE ISSUE
General Plan Amendment
The applicant is proposing a General Plan Amendment (GPA) for three specific reasons:

1. To bring the existing General Plan land use designation for the site into a higher level of consistency with the existing Limited Commercial zoning.

2. To remove the existing general plan designation of Medium Density Residential and replace it with the General Commercial land Use designation. The existing Medium Density Residential land use designation has a maximum density of 17 units per acre whereas the General Commercial land use designation has a maximum density of 29 units. This will permit the proposed project density of 25 units per acre.

The proposed GPA to General Commercial is appropriate for the site and the surrounding area as the site is currently zoned Limited Commercial. The surrounding area is a combination of traditional single family detached residential and multi-family residential to the south, west and east. The proposed GPA will allow the proposed project to develop a vacant successor agency owned property into 50 new market rate and 10 affordable housing units.

Change of Zone
The project is requesting a zone change to remove the existing Parking overlay zoning (P) on the southern half of the site resulting in a site with only Limited Commercial zoning (100%). The proposed zone change will give the site a single Limited Commercial (CL) zoning that permits high density residential development with a Conditional Use Permit.

Conditional Use Permit
The proposed CUP is to permit the development of a gated 60-unit attached condominium unit project with attached two car garages, a common open space area, and 15 guest parking spaces in the Limited Commercial zone. Zoning code section 30-12.2(b) permits residential development in the Limited Commercial zone subject to an approved Conditional Use Permit.

Access/Circulation
Vehicle ingress/egress to the development will be from two gated access points on 151st Street with a secondary emergency access from Compton Blvd. also proposed. The primary access into the site will be from the gated entrance 60 feet from Kemp Street. This access is designed with a 25-foot radius circular turn around with a gate set back 50 feet from the property line allowing for two vehicles to que without blocking the sidewalk. Residents will have remote access to the gate, but there will also be a key pad for guests. Visitors denied entrance would use the turn around to exit the site without having to back up.

The other gated access point will also be on 151st street 60 feet from Dwight Street (SEC) and serve primarily as an exit only, but will permit resident only ingress by remote. The two access driveways from 151st Street connect to the primary internal driveway aisle providing one continuous path of two-way travel. Connecting from this primary internal street are four smaller 22-foot wide driveways that will provide direct access to each garage. There is 28 feet of back up distance behind each garage door to provide sufficient back up room. The driveways range in depth from 40 to 95 feet Staff Report – City Council Appeal of CUP Case No. 21-008 and MND No. 951 June 28, 2022

serving from three to ten units. The emergency access proposed for the NWC of Compton Blvd. and Dwight will remain closed and only opened by the Fire Department if needed.

Proposed Units
There will be four building types identified as either a 5-Plex, 6 plex, 8 plex or 10-Plex. These building types will contain either five, six, eight or ten units in a single building with a mix of three different unit types, (P1, P2 and P3).

The proposed units will have three and four bedrooms with three to four bathrooms. All units have an attached 2-car side by side or tandem garage. Each ground floor unit will have a front porch space, and a second-floor balcony for private space with the exception of units 44, 45, 54, 55 that will have second floor balconies only. Some units will also have a third-floor balcony in addition to a patio and second floor balcony.

Refer to the table below for the unit type breakdown.

(Tandem
Amenities
Amenities are not required by zoning code for multi-family development in the CL zone. Projects are only required to provide a minimum of 100 square feet of usable accessible open space per unit.

The common open space proposed by the project is divided into two areas. The larger 40 x 95 foot area is located in the center of the site. The smaller area is located at the western end of the site adjacent the gated entrance and units 59 and 60. The total common open space area proposed is approximately 7,284 square feet and contains amenities such as a grass area, BBQ’s, tables, and shade structure. In addition to the common open space, the project is proposing 13,583 square feet of private open space consisting of patios and balconies. The combination of the 13,583 square foot private and 7,284 square foot common open space totals 20,867 square feet and more than satisfies the required minimum of 5,700 square feet (100 square feet per unit) of common open space. The mailboxes for the project are also located at the edge of the common open space area.

Staff has reviewed the private/common open space and amenities proposed and finds them acceptable and exceeds the minimum requirements of the zoning code.

Guest Parking
The project is proposing 15 guest parking spaces in four areas. Guest parking will be near each access point and in the center of the project to facilitate easy use by visiting guests. This meets the code minimum of 15 spaces.

Tentative Tract Map
Staff Report – City Council Appeal of CUP Case No. 21-008 and MND No. 951 June 28, 2022

The proposed condominium Tentative Tract Map is needed in order to facilitate the creation of condominiums and allow the units to be sold individually. One master lot is proposed with airspace rights for 60 dwelling units.

Traffic Impact Study
A Traffic Impact Analysis/Study was prepared for the proposed development by TJW Engineering Inc. The report evaluated the potential traffic impacts created by the proposed development. The study identified that the project will not have any adverse impact to circulation.

A Mitigated Negative Declaration was prepared for the project. The Initial Study/Mitigated Negative Declaration No. 951 was posted with the Los Angeles County Clerk’s office in Norwalk, circulated for a 20-day public review period from November 16, 2021 to December 5, 202. The proposed project will not cause any negative impacts.

FINANCIAL IMPACT
None. No City funds will be used for this project.

RECOMMENDATION
Staff makes no recommendation regarding this appeal. Pursuant to Section 30-26.5(k) of the Compton Municipal Code, the City Council shall render its decision on the appeal within thirty (30) days after conclusion of the appeal hearing and has the power to:
 Affirm the decision of the Planning Commission; or
 Amend the decision of the Planning Commission; or
 Overturn the decision of the Planning Commission; or
 If in the opinion of the Council, the matter requires further consideration, refer the matter back to the Planning Commission for further consideration (without a decision by the Council) with any recommendations the Council may desire.

1 1.0 Introduction

1.1 Purpose of Analysis and Study Objectives
This air quality and greenhouse gas (GHG) analysis was prepared to evaluate whether the estimated criteria pollutants and GHG emissions generated from the project would cause a significant impact to the air resources in the project area. This assessment was conducted within the context of the California Environmental Quality Act (CEQA, California Public Resources Code Sections 21000, et seq.). The assessment is consistent with the methodology and emission factors endorsed by South Coast Air Quality Management District (SCAQMD), California Air Resource Board (CARB), and the United States Environmental Protection Agency (US EPA).

1.2 Project Summary

1.2.1 Site Location
The project site is located at 930 W. Compton Boulevard in Compton, California, as shown in Exhibit A.

The site is currently zoned as Limited Commercial (CL) and Parking (P) and classified as Medium Density Residential (8.1-17.0 dwelling units per acre) in the City of Compton General Plan. The project includes a Change of Zone to General Commercial – Limited Commercial and Planned Development (C-L-D).The proposed use is multi-family residential at approximately 24.5 dwelling units per acre. Land uses surrounding the site include single-family residential uses to the south (across 151st Street), single-family residential uses and commercial uses to the west (across Dwight Avenue), mixed-use commercial and residential uses to the north (across Compton Boulevard), and multi-family residential uses to the east (across Kemp Avenue).

1.2.2 Project Description
The Project proposes the development of the approximately 2.45-acre site with 60 single-family (attached) townhomes. Exhibit B demonstrates the site plan for the project.

Construction activities within the Project area will consist of on-site grading, building, paving, and architectural coating. Table 1 summarizes the land use description for the Project Site.

2 1
The Traffic & Parking Analysis for the Compton & Kemp Residential Project (TJW Engineering, Inc., March 3, 2021) utilized land use code Multi-Family Housing (Low-Rise) ITE 220. Therefore, the project was modeled with the closest land use code available in CalEEMod, Apartments Low Rise (ITE 221).

1.2.3 Sensitive Receptors
Sensitive receptors are considered land uses or other types of population groups that are more sensitive to air pollution than others due to their exposure. Sensitive population groups include children, the elderly, the acutely and chronically ill, and those with cardio-respiratory diseases. For CEQA purposes, a sensitive receptor would be a location where a sensitive individual could remain for 24-hours or longer, such as residencies, hospitals, and schools (etc).

The closest existing sensitive receptors (to the site area) are multiple-family residential land useslocated approximately 35 feet southeast and 50 foot east of the project site (across Kemp Avenue). In addition, single-family residential land uses are located approximately 50 feet south of the project site (across 151st Street), 50 feet west of the project site (across Dwight Avenue), and 165 feet north of the project site.

1.3 Executive Summary of Findings and Mitigation Measures The following is a summary of the analysis results:

Construction-Source Emissions
Project construction-source emissions would not exceed applicable regional thresholds of significance established by the SCAQMD. For localized emissions, the project will not exceed applicable Localized Significance Thresholds (LSTs) established by the SCAQMD.

Project construction-source emissions would not conflict with the Basin Air Quality Management Plan (AQMP). As discussed herein, the project will comply with all applicable SCAQMD construction-source emission reduction rules and guidelines. Project construction source emissions would not cause or substantively contribute to violation of the California Ambient Air Quality Standards (CAAQS) or National Ambient Air Quality Standards (NAAQS).

Established requirements addressing construction equipment operations, and construction material use, storage, and disposal requirements act to minimize odor impacts that may result from construction activities. Moreover, construction-source odor emissions would be temporary, short-term, and intermittent in nature and would not result in persistent impacts that would affect substantial numbers of people. Potential construction-source odor impacts are therefore considered less-than-significant.

Operational-Source Emissions
The project operational-sourced emissions would not exceed applicable regional thresholds of significance established by the SCAQMD. Project operational-source emissions would not result in or cause a significant localized air quality impact as discussed in the Operations-Related Local Air Quality Impacts section of this report. Additionally, project-related traffic will not cause or result in CO concentrations exceeding applicable state and/or federal standards (CO “hotspots). Project operational- Compton Residential Development
Air Quality and Greenhouse Gas Impact Study
City of Compton, CA Introduction
3 source emissions would therefore not adversely affect sensitive receptors within the vicinity of the project.

Project operational-source emissions would not conflict with the Basin Air Quality Management Plan (AQMP). The project's emissions meet SCAQMD regional thresholds and will not result in a significant cumulative impact. The project does not propose any such uses or activities that would result in potentially significant operational-source odor impacts. Potential operational-source odor impacts are therefore considered less-than significant.

Project-related GHG emissions meet the SCAQMD draft threshold and are also considered to be less than significant. The project also complies with the goals of the CARB Scoping Plan, AB-32, and SB-32.

Mitigation Measures
A. Construction Measures
Adherence to SCAQMD Rule 403 is required.

No construction mitigation required.

B. Operational Measures
No operational mitigation required.

City of Compton, CA Regulatory Framework and Background 6 2.0 Regulatory Framework and Background

2.1 Air Quality Regulatory Setting
Air pollutants are regulated at the national, state, and air basin level; each agency has a different level of regulatory responsibility. The United States Environmental Protection Agency (EPA) regulates at the national level. The California Air Resources Board (ARB) regulates at the state level. The South Coast Air Quality Management District (SCAQMD) regulates at the air basin level.

2.1.1 National and State
The EPA is responsible for global, international, and interstate air pollution issues and policies. The EPA sets national vehicle and stationary source emission standards, oversees approval of all State Implementation Plans, provides research and guidance for air pollution programs, and sets National Air Quality Standards, also known as federal standards. There are six common air pollutants, called criteria pollutants, which were identified from the provisions of the Clean Air Act of 1970. • Ozone
• Nitrogen Dioxide
• Lead
• Particulate Matter (PM10 and PM2.5)
• Carbon Monoxide
• Particulate Matter
• Sulfur Dioxide
The federal standards were set to protect public health, including that of sensitive individuals; thus, the standards continue to change as more medical research is available regarding the health effects of the criteria pollutants. Primary federal standards are the levels of air quality necessary, with an adequate margin of safety, to project the public health.

A State Implementation Plan is a document prepared by each state describing existing air quality conditions and measures that will be followed to attain and maintain federal standards. The State Implementation Plan for the State of California is administered by the ARB, which has overall responsibility for statewide air quality maintenance and air pollution prevention. California’s State Implementation Plan incorporates individual federal attainment plans for regional air districts—air district prepares their federal attainment plan, which sent to ARB to be approved and incorporated into the California State Implementation Plan. Federal attainment plans include the technical foundation for understanding air quality (e.g., emission inventories and air quality monitoring), control measures and strategies, and enforcement mechanisms. See http://www.arb.ca.gov/research/aaqs/aaqs.htm for additional information on criteria pollutants and air quality standards.

The federal and state ambient air quality standards are summarized in Table 2 and can also be found at http://www.arb.ca.gov/research/aaqs/aaqs2.pdf.

1. California standards for ozone, carbon monoxide (except 8-hour Lake Tahoe), sulfur dioxide (1 and 24 hour), nitrogen dioxide, and particulate matter (PM10, PM2.5, and visibility reducing particles), are values that are not to be exceeded. All others are not to be equaled or exceeded. California ambient air quality standards are listed in the Table of Standards in Section 70200 of Title 17 of the California Code of Regulations.

2. National standards (other than ozone, particulate matter, and those based on annual arithmetic mean) are not to be exceeded more than once a year.

The ozone standard is attained when the fourth highest 8-hour concentration measured at each site in a year, averaged over three years, is equal to or less than the standard. For PM10, the 24 hour standard is attained when the expected number of days per calendar year with a 24-hour average concentration above 150 μg/m3is equal to or less than one. For PM2.5, the 24 hour standard is attained when 98 percent of the daily concentrations, averaged over three years, are equal to or less than the standard. Contact the U.S. EPA for further clarification and current national policies.

3. Concentration expressed first in units in which it was promulgated. Equivalent units given in parentheses are based upon a reference temperature of 25°C and a reference pressure of 760 torr. Most measurements of air quality are to be corrected to a reference temperature of 25°C and a reference pressure of 760 torr; ppm in this table refers to ppm by volume, or micromoles of pollutant per mole of gas.

4. Any equivalent measurement method which can be shown to the satisfaction of the ARB to give equivalent results at or near the level of the air quality standard may be used.

5. National Primary Standards: The levels of air quality necessary, with an adequate margin of safety to protect the public health.

6. National Secondary Standards: The levels of air quality necessary to protect the public welfare from any known or anticipated adverse effects of a pollutant.

7. Reference method as described by the U.S. EPA. An “equivalent method” of measurement may be used but must have a “consistent relationship to the reference method” and must be approved by the U.S. EPA.

Compton Residential Development
Air Quality and Greenhouse Gas Impact Study
City of Compton, CA Regulatory Framework and Background 8 8. On December 14, 2012, the national annual PM2.5 primary standard was lowered from 15 μg/m3to 12.0 μg/m3. The existing national 24-hour PM2.5 standards (primary and secondary) were retained at 35 μg/m3, as was the annual secondary standard of 15 μg/m3. The existing 24-hour PM10 standards (primary and secondary) of 150 μg/m3also were retained. The form of the annual primary and secondary standards is the annual mean, averaged over 3 years.

9. To attain the 1-hour national standard, the 3-year average of the annual 98th percentile of the 1-hour daily maximum concentrations at each site must not exceed 100 ppb. Note that the national 1-hour standard is in units of parts per billion (ppb). California standards are in units of parts per million (ppm). To directly compare the national 1-hour standard to the California standards the units can be converted from ppb to ppm. In this case, the national standard of 100 ppb is identical to 0.100 ppm.

10. On June 2, 2010, a new 1-hour SO2 standard was established and the existing 24-hour and annual primary standards were revoked. To attain the 1- hour national standard, the 3-year average of the annual 99th percentile of the 1-hour daily maximum concentrations at each site must not exceed 75 ppb. The 1971 SO2 national standards (24-hour and annual) remain in effect until one year after an area is designated for the 2010 standard, except that in areas designated nonattainment for the 1971 standards, the 1971 standards remain in effect until implementation plans to attain or maintain the 2010 standards are approved.

Note that the 1-hour national standard is in units of parts per billion (ppb). California standards are in units of parts per million (ppm). To directly compare the 1-hour national standard to the California standard the units can be converted to ppm. In this case, the national standard of 75 ppb is identical to 0.075 ppm.

11. The ARB has identified lead and vinyl chloride as 'toxic air contaminants' with no threshold level of exposure for adverse health effects determined.

These actions allow for the implementation of control measures at levels below the ambient concentrations specified for these pollutants.

12. The national standard for lead was revised on October 15, 2008 to a rolling 3-month average. The 1978 lead standard (1.5 μg/m3as a quarterly average) remains in effect until one year after an area is designated for the 2008 standard, except that in areas designated nonattainment for the 1978 standard, the 1978 standard remains in effect until implementation plans to attain or maintain the 2008 standard are approved.

13. In 1989, the ARB converted both the general statewide 10-mile visibility standard and the Lake Tahoe 30-mile visibility standard to instrumental equivalents, which are "extinction of 0.23 per kilometer" and "extinction of 0.07 per kilometer" for the statewide and Lake Tahoe Air Basin standards, respectively.

Several pollutants listed in Table 2 are not addressed in this analysis. Analysis of lead is not included in this report because the project is not anticipated to emit lead. Visibility-reducing particles are not explicitly addressed in this analysis because particulate matter is addressed. The project is not expected to generate or be exposed to vinyl chloride because proposed project uses do not utilize the chemical processes that create this pollutant and there are no such uses in the project vicinity. The proposed project is not expected to cause exposure to hydrogen sulfide because it would not generate hydrogen sulfide in any substantial quantity.

2.1.2 South Coast Air Quality Management District
The agency for air pollution control for the South Coast Air Basin (basin) is the South Coast Air Quality Management District (SCAQMD). SCAQMD is responsible for controlling emissions primarily from stationary sources. SCAQMD maintains air quality monitoring stations throughout the basin. SCAQMD, in coordination with the Southern California Association of Governments, is also responsible for developing, updating, and implementing the Air Quality Management Plan (AQMP) for the basin. An AQMP is a plan prepared and implemented by an air pollution district for a county or region designated as nonattainment of the federal and/or California ambient air quality standards. The term nonattainment area is used to refer to an air basin where one or more ambient air quality standards are exceeded.

Every three (3) years the SCAQMD prepares a new AQMP, updating the previous plan and having a 20- year horizon.

Compton Residential Development
Air Quality and Greenhouse Gas Impact Study
City of Compton, CA Regulatory Framework and Background 9 On March 23, 2017 CARB approved the 2016 AQMP. The 2016 AQMP is a regional blueprint for achieving the federal air quality standards and healthful air. The Plan was approved by the EPA on June 15, 2017.

The 2016 AQMP includes both stationary and mobile source strategies to ensure that rapidly approaching attainment deadlines are met, that public health is protected to the maximum extent feasible, and that the region is not faced with burdensome sanctions if the Plan is not approved or if the NAAQS are not met on time. As with every AQMP, a comprehensive analysis of emissions, meteorology, atmospheric chemistry, regional growth projections, and the impact of existing control measures is updated with the latest data and methods. The most significant air quality challenge in the Basin is to reduce nitrogen oxide (NOx) emissions sufficiently to meet the upcoming ozone standard deadlines. The primary goal of this Air Quality Management Plan is to meet clean air standards and protect public health, including ensuring benefits to environmental justice and disadvantaged communities. The Plan was approved by the EPA on June 15, 2017
The 2012 AQMP built upon the approaches taken in the 2007 AQMP for the attainment of federal PM and ozone standards, and highlights the significant amount of reductions needed and the need to engage in interagency coordinated planning of mobile sources to meet all of the federal criteria pollutant standards. Compared with the 2007 AQMP, the 2012 AQMP utilized revised emissions inventory projections that use 2008 as the base year. On-road emissions are calculated using CARB EMFAC2011 emission factors and the transportation activity data provided by SCAG from their 2012 Regional Transportation Plan (2012 RTP). Off-road emissions were updated using CARB’s 2011 In-Use Off-Road Fleet Inventory Model. Since the 2007 AQMP was finalized new area source categories such as liquid propane gas (LPG) transmission losses, storage tank and pipeline cleaning and degassing, and architectural colorants, were created and included in the emissions inventories. The 2012 AQMP also includes analysis of several additional sources of GHG emissions such as landfills and could also assist in reaching the GHG target goals in the AB32 Scoping Plan.

South Coast Air Quality Management District Rules
The AQMP for the basin establishes a program of rules and regulations administered by SCAQMD to obtain attainment of the state and federal standards. Some of the rules and regulations that apply to this Project include, but are not limited to, the following:

SCAQMD Rule 402 prohibits a person from discharging from any source whatsoever such quantities of air contaminants or other material which cause injury, detriment, nuisance, or annoyance to any considerable number of persons or to the public, or which endanger the comfort, repose, health or safety of any such persons or the public, or which cause, or have a natural tendency to cause, injury or damage to business or property.

SCAQMD Rule 403 governs emissions of fugitive dust during construction and operation activities.

Compliance with this rule is achieved through application of standard Best Management Practices, such as application of water or chemical stabilizers to disturbed soils, covering haul vehicles, restricting vehicle speeds on unpaved roads to 15 miles per hour, sweeping loose dirt from paved site access roadways, cessation of construction activity when winds exceed 25 mph, and establishing a permanent ground cover on finished sites.

Compton Residential Development
Air Quality and Greenhouse Gas Impact Study
City of Compton, CA Regulatory Framework and Background 10 Rule 403 requires that fugitive dust be controlled with best available control measures so that the presence of such dust does not remain visible in the atmosphere beyond the property line of the emission source. In addition, Rule 403 requires implementation of dust suppression techniques to prevent fugitive dust from creating a nuisance off site. Applicable suppression techniques are indicated below and include but are not limited to the following:
• Apply nontoxic chemical soil stabilizers according to manufacturers’ specifications to all inactive construction areas (previously graded areas in active for 10 days or more). • Water active sites at least three times daily.
• Cover all trucks hauling dirt, san, soil, or other loose materials, or maintain at least 2 feet of freeboard in accordance with the requirements of California Vehicle Code (CVC) section 23114. • Pave construction access roads at least 100 feet onto the site from the main road. • Reduce traffic speeds on all unpaved roads to 15 mph or less. • Suspension of all grading activities when wind speeds (including instantaneous wind gusts) exceed 25 mph.
• Bumper strips or similar best management practices shall be provided where vehicles enter and exit the construction site onto paved roads or wash off trucks and any equipment leaving the site each trip.
• Replanting disturbed areas as soon as practical.
• During all construction activities, construction contractors shall sweep on-site and off-iste streets if silt is carried to adjacent public thoroughfares, to reduce the amount of particulate matter on public streets.

SCAQMD Rule 1113 governs the sale, use, and manufacturing of architectural coating and limits the VOC content in paints and paint solvents. This rule regulates the VOC content of paints available during construction. Therefore, all paints and solvents used during construction and operation of project must comply with Rule 1113.

Idling Diesel Vehicle Trucks – Idling for more than 5 minutes in any one location is prohibited within California borders.

Rule 2702. The SCAQMD adopted Rule 2702 on February 6, 2009, which establishes a voluntary air quality investment program from which SCAQMD can collect funds from parties that desire certified GHG emission reductions, pool those funds, and use them to purchase or fund GHG emission reduction projects within two years, unless extended by the Governing Board. Priority will be given to projects that result in co-benefit emission reductions of GHG emissions and criteria or toxic air pollutants within environmental justice areas. Further, this voluntary program may compete with the cap-and-trade program identified for implementation in CARB’s Scoping Plan, or a Federal cap and trade program.

Air Quality and Greenhouse Gas Impact Study
City of Compton, CA Regulatory Framework and Background 11 2.2 Greenhouse Gas Regulatory Setting

2.2.1 International
Many countries around the globe have made an effort to reduce GHGs since climate change is a global issue.

Intergovernmental Panel on Climate Change. In 1988, the United Nations and the World Meteorological Organization established the Intergovernmental Panel on Climate Change to assess the scientific, technical and socio-economic information relevant to understanding the scientific basis of risk of humaninduced climate change, its potential impacts, and options for adaptation and mitigation.

United Nations. The United States participates in the United Nations Framework Convention on Climate Change (UNFCCC) (signed on March 21, 1994). Under the Convention, governments gather and share information on greenhouse gas emissions, national policies, and best practices; launch national strategies for addressing greenhouse gas emissions and adapting to expected impacts, including the provision of financial and technological support to developing countries; and cooperate in preparing for adaptation to the impacts of climate change.

The 2014 UN Climate Change Conference in Lima Peru provided a unique opportunity to engage all countries to assess how developed countries are implementing actions to reduce emissions.

Kyoto Protocol. The Kyoto Protocol is a treaty made under the UNFCCC and was the first international agreement to regulate GHG emissions. It has been estimated that if the commitments outlined in the Kyoto Protocol are met, global GHG emissions could be reduced by an estimated 5 percent from 1990 levels during the first commitment period of 2008 – 2012 (UNFCCC 1997). On December 8, 2012, the Doha Amendment to the Kyoto Protocol was adopted. The amendment includes: New commitments for Annex I Parties to the Kyoto Protocol who agreed to take on commitments in a second commitment period from 2013 – 2020; a revised list of greenhouse gases (GHG) to be reported on by Parties in the second commitment period; and Amendments to several articles of the Kyoto Protocol which specifically referenced issues pertaining to the first commitment period and which needed to be updated for the second commitment period.

2.2.2 National
Greenhouse Gas Endangerment. On December 2, 2009, the EPA announced that GHGs threaten the public health and welfare of the American people. The EPA also states that GHG emissions from on-road vehicles contribute to that threat. The decision was based on Massachusetts v. EPA (Supreme Court Case 05-1120) which argued that GHGs are air pollutants covered by the Clean Air Act and that the EPA has authority to regulate those emissions.

Clean Vehicles. Congress first passed the Corporate Average Fuel Economy law in 1975 to increase the fuel economy of cars and light duty trucks. The law has become more stringent over time. On May 19, 2009, President Obama put in motion a new national policy to increase fuel economy for all new cars and trucks sold in the United States. On April 1, 2010, the EPA and the Department of Transportation’s Compton Residential Development
Air Quality and Greenhouse Gas Impact Study
City of Compton, CA Regulatory Framework and Background 12 National Highway Safety Administration announced a joint final rule establishing a national program that would reduce greenhouse gas emissions and improve fuel economy for new cars and trucks sold in the United States.

The first phase of the national program would apply to passenger cars, light-duty trucks, and mediumduty passenger vehicles, covering model years 2012 through 2016. They require these vehicles to meet an estimated combined average emissions level of 250 grams of carbon dioxide per mile, equivalent to

35.5 miles per gallon if the automobile industry were to meet this carbon dioxide level solely through fuel economy improvements. Together, these standards would cut carbon dioxide emissions by an estimated 960 million metric tons and 1.8 billion barrels of oil over the lifetime of the vehicles sold under the program (model years 2012-2016). The second phase of the national program would involve proposing new fuel economy and greenhouse gas standards for model years 2017 – 2025 by September 1, 2011.

On October 25, 2010, the EPA and the U.S. Department of Transportation proposed the first national standards to reduce greenhouse gas emissions and improve fuel efficiency of heavy-duty trucks and buses. For combination tractors, the agencies are proposing engine and vehicle standards that begin in the 2014 model year and achieve up to a 20 percent reduction in carbon dioxide emissions and fuel consumption by the 2018 model year. For heavy-duty pickup trucks and vans, the agencies are proposing separate gasoline and diesel truck standards, which phase in starting in the 2014 model year and achieve up to a 10 percent reduction for gasoline vehicles and 15 percent reduction for diesel vehicles by 2018 model year (12 and 17 percent respectively if accounting for air conditioning leakage). Lastly, for vocational vehicles, the agencies are proposing engine and vehicle standards starting in the 2014 model year which would achieve up to a 10 percent reduction in fuel consumption and carbon dioxide emissions by 2018 model year.

Mandatory Reporting of Greenhouse Gases. On January 1, 2010, the EPA started requiring large emitters of heat-trapping emissions to begin collecting GHG data under a new reporting system. Under the rule, suppliers of fossil fuels or industrial greenhouse gases, manufacturers of vehicles and engines, and facilities that emit 25,000 metric tons or more per year of greenhouse gas emissions are required to submit annual reports to the EPA.

Climate Adaption Plan. The EPA Plan identifies priority actions the Agency will take to incorporate considerations of climate change into its programs, policies, rules and operations to ensure they are effective under future climatic conditions.

2.2.3 California
California Code of Regulations (CCR) Title 24, Part 6. CCR Title 24, Part 6: California’s Energy Efficiency Standards for Residential and Nonresidential Buildings (Title 24) were first established in 1978 in response to a legislative mandate to reduce California’s energy consumption. The standards are updated periodically to allow consideration and possible incorporation of new energy efficiency technologies and methods. Although it was not originally intended to reduce GHG emissions, electricity production by Compton Residential Development
Air Quality and Greenhouse Gas Impact Study
City of Compton, CA Regulatory Framework and Background 13 fossil fuels results in GHG emissions and energy efficient buildings require less electricity. Therefore, increased energy efficiency results in decreased GHG emissions.

The Energy Commission adopted 2008 Standards on April 23, 2008 and Building Standards Commission approved them for publication on September 11, 2008. These updates became effective on August 1, 2009. 2013 and 2016 standards have been approved and became effective July 1, 2014 and January 1, 2016, respectively.

California Code of Regulations (CCR) Title 24, Part 11. All buildings for which an application for a building permit is submitted on or after January 1, 2020 must follow the 2019 standards. Energy efficient buildings require less electricity; therefore, increased energy efficiency reduces fossil fuel consumption and decreases greenhouse gas emissions. The following links provide more information on Title 24, Part 11:
https://www.dgs.ca.gov/BSC/Codes
https://www.energy.ca.gov/sites/default/files/2020-03/Title_24_2019_Building_Standards_FAQ_ada.pdf California Green Building Standards. On January 12, 2010, the State Building Standards Commission unanimously adopted updates to the California Green Building Standards Code, which went into effect on January 1, 2011. The Housing and Community Development (HCD) updated CALGreen through the 2015 Triennial Code Adoption Cycle, during the 2016 to 2017 fiscal year. During the 2019-2020 fiscal year, the Department of Housing and Community Development (HCD) updated CALGreen through the 2019 Triennial Code Adoption Cycle.

The Code is a comprehensive and uniform regulatory code for all residential, commercial and school buildings. CCR Title 24, Part 11: California Green Building Standards (Title 24) became effective in 2001 in response to continued efforts to reduce GHG emissions associated with energy consumption. CCR Title 24, Part 11 now require that new buildings reduce water consumption, employ building commissioning to increase building system efficiencies, divert construction waste from landfills, and install low pollutant-emitting finish materials. One focus of CCR Title 24, Part 11 is water conservation measures, which reduce GHG emissions by reducing electrical consumption associated with pumping and treating water. CCR Title 24, Part 11 has approximately 52 nonresidential mandatory measures and an additional 130 provisions for optional use. Some key mandatory measures for commercial occupancies include specified parking for clean air vehicles, a 20 percent reduction of potable water use within buildings, a 50 percent construction waste diversion from landfills, use of building finish materials that emit low levels of volatile organic compounds, and commissioning for new, nonresidential buildings over 10,000 square feet.

The 2019 CalGreen Code includes the following changes and/or additional regulations:

Single-family homes built with the 2019 standards will use about 7 percent less energy due to energy efficiency measures versus those built under the 2016 standards. Once rooftop solar electricity generation is factored in, homes built under the 2019 standards will use about 53 percent less energy Compton Residential Development

City of Compton, CA Regulatory Framework and Background 14 than those under the 2016 standards. Nonresidential buildings will use about 30 percent less energy due mainly to lighting upgrades1.

HCD modified the best management practices for stormwater pollution prevention adding Section

5.106.2 for projects that disturb one or more acres of land. This section requires projects that disturb one acre or more of land or less than one acre of land but are part of a larger common plan of development or sale must comply with the post-construction requirement detailed in the applicable National Pollutant Discharge Elimination System (NPDES) General Permit for Stormwater Discharges Associated with Construction and Land Disturbance Activities issued by the State Water Resources Control Board. The NPDES permits require post-construction runoff (post-project hydrology) to match the preconstruction runoff pre-project hydrology) with installation of post-construction stormwater management measures.

HCD added sections 5.106.4.1.3 and 5.106.4.1.5 in regards to bicycle parking. Section 5.106.4.1.3 requires new buildings with tenant spaces that have 10 or more tenant-occupants, provide secure bicycle parking for 5 percent of the tenant-occupant vehicular parking spaces with a minimum of one bicycle parking facility. In addition, Section 5.106.4.1.5 states that acceptable bicycle parking facility for Sections 5.106.4.1.2 through 5.106.4.1.4 shall be convenient from the street and shall meeting one of the following: (1) covered, lockable enclosures with permanently anchored racks for bicycles; (2) lockable bicycle rooms with permanently anchored racks; or (3) lockable, permanently anchored bicycle lockers.

HCD amended section 5.106.5.3.5 allowing future charging spaces to qualify as designated parking for clean air vehicles.

HCD updated section 5.303.3.3 in regards to showerhead flow rates. This update reduced the flow rate to 1.8 GPM.

HCD amended section 5.304.1 for outdoor potable water use in landscape areas and repealed sections

5.304.2 and 5.304.3. The update requires nonresidential developments to comply with a local water efficient landscape ordinance or the current California Department of Water Resource’s’ Model Water Efficient Landscape Ordinance (MWELO), whichever is more stringent. Some updates were also made in regards to the outdoor potable water use in landscape areas for public schools and community colleges.

HCD updated Section 5.504.5.3 in regards to the use of MERV filters in mechanically ventilated buildings.

This update changed the filter use from MERV 8 to MERV 13.

The California Green Building Standards Code does not prevent a local jurisdiction from adopting a more stringent code as state law provides methods for local enhancements.

Executive Order S-3-05. California Governor issued Executive Order S-3-05, GHG Emission, in June 2005, which established the following targets:
• By 2010, California shall reduce greenhouse gas emissions to 2000 levels; • By 2020, California shall reduce greenhouse gas emissions to 1990 levels. • By 2050, California shall reduce greenhouse gas emissions to 80 percent below 1990 levels.

The executive order directed the secretary of the California Environmental Protection Agency (CalEPA) to coordinate a multi-agency effort to reduce GHG emissions to the target levels. To comply with the Executive Order, the secretary of CalEPA created the California Climate Action Team (CAT), made up of members from various state agencies and commissions. The team released its first report in March 2006. The report proposed to achieve the targets by building on the voluntary actions of businesses, local governments, and communities and through State incentive and regulatory programs.

Executive Order S-01-07. Executive Order S-1-07 was issued in 2007 and proclaims that the transportation sector is the main source of GHG emissions in the State, since it generates more than 40 percent of the State’s GHG emissions. It establishes a goal to reduce the carbon intensity of transportation fuels sold in the State by at least ten percent by 2020. This Order also directs CARB to determine whether this Low Carbon Fuel Standard (LCFS) could be adopted as a discrete early-action measure as part of the effort to meet the mandates in AB 32.

On April 23, 2009 CARB approved the proposed regulation to implement the low carbon fuel standard.

The low carbon fuel standard is anticipated to reduce GHG emissions by about 16 MMT per year by 2020.

The low carbon fuel standard is designed to provide a framework that uses market mechanisms to spur the steady introduction of lower carbon fuels. The framework establishes performance standards that fuel producers and importers must meet each year beginning in 2011. Separate standards are established for gasoline and diesel fuels and the alternative fuels that can replace each. The standards are “back-loaded”, with more reductions required in the last five years, than the first five years. This schedule allows for the development of advanced fuels that are lower in carbon than today’s fuels and the market penetration of plug-in hybrid electric vehicles, battery electric vehicles, fuel cell vehicles, and flexible fuel vehicles. It is anticipated that compliance with the low carbon fuel standard will be based on a combination of both lower carbon fuels and more efficient vehicles.

Reformulated gasoline mixed with corn-derived ethanol at ten percent by volume and low sulfur diesel fuel represent the baseline fuels. Lower carbon fuels may be ethanol, biodiesel, renewable diesel, or Compton Residential Development
Air Quality and Greenhouse Gas Impact Study
City of Compton, CA Regulatory Framework and Background 16 blends of these fuels with gasoline or diesel as appropriate. Compressed natural gas and liquefied natural gas also may be low carbon fuels. Hydrogen and electricity, when used in fuel cells or electric vehicles are also considered as low carbon fuels for the low carbon fuel standard.

SB 97. Senate Bill 97 (SB 97) was adopted August 2007 and acknowledges that climate change is a prominent environmental issue that requires analysis under CEQA. SB 97 directed the Governor’s Office of Planning and Research (OPR), which is part of the State Resource Agency, to prepare, develop, and transmit to CARB guidelines for the feasible mitigation of GHG emissions or the effects of GHG emissions, as required by CEQA, by July 1, 2009. The Resources Agency was required to certify and adopt those guidelines by January 1, 2010.

Pursuant to the requirements of SB 97 as stated above, on December 30, 2009 the Natural Resources Agency adopted amendments to the state CEQA guidelines that address GHG emissions. The CEQA Guidelines Amendments changed 14 sections of the CEQA Guidelines and incorporate GHG language throughout the Guidelines. However, no GHG emissions thresholds of significance are provided and no specific mitigation measures are identified. The GHG emission reduction amendments went into effect on March 18, 2010 and are summarized below:
• Climate action plans and other greenhouse gas reduction plans can be used to determine whether a project has significant impacts, based upon its compliance with the plan. • Local governments are encouraged to quantify the greenhouse gas emissions of proposed projects, noting that they have the freedom to select the models and methodologies that best meet their needs and circumstances. The section also recommends consideration of several qualitative factors that may be used in the determination of significance, such as the extent to which the given project complies with state, regional, or local GHG reduction plans and policies. OPR does not set or dictate specific thresholds of significance. Consistent with existing CEQA Guidelines, OPR encourages local governments to develop and publish their own thresholds of significance for GHG impacts assessment.
• When creating their own thresholds of significance, local governments may consider the thresholds of significance adopted or recommended by other public agencies, or recommended by experts. • New amendments include guidelines for determining methods to mitigate the effects of greenhouse gas emissions in Appendix F of the CEQA Guidelines.
• OPR is clear to state that “to qualify as mitigation, specific measures from an existing plan must be identified and incorporated into the project; general compliance with a plan, by itself, is not mitigation.”
• OPR’s emphasizes the advantages of analyzing GHG impacts on an institutional, programmatic level.

OPR therefore approves tiering of environmental analyses and highlights some benefits of such an approach.
• Environmental impact reports (EIRs) must specifically consider a project's energy use and energy efficiency potential.

AB 32. The California State Legislature enacted AB 32, the California Global Warming Solutions Act of 2006. AB 32 requires that greenhouse gases emitted in California be reduced to 1990 levels by the year Compton Residential Development
Air Quality and Greenhouse Gas Impact Study
City of Compton, CA Regulatory Framework and Background 17 2020. “Greenhouse gases” as defined under AB 32 include carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride. ARB is the state agency charged with monitoring and regulating sources of greenhouse gases. AB 32 states the following:

Global warming poses a serious threat to the economic well-being, public health, natural resources, and the environment of California. The potential adverse impacts of global warming include the exacerbation of air quality problems, a reduction in the quality and supply of water to the state from the Sierra snowpack, a rise in sea levels resulting in the displacement of thousands of coastal businesses and residences, damage to marine ecosystems and the natural environment, and an increase in the incidences of infectious diseases, asthma, and other human health-related problems.

The ARB Board approved the 1990 greenhouse gas emissions level of 427 million metric tons of carbon dioxide equivalent (MMTCO2e) on December 6, 2007 (California Air Resources Board 2007). Therefore, emissions generated in California in 2020 are required to be equal to or less than 427 MMTCO2e.

Emissions in 2020 in a “business as usual” scenario are estimated to be 596 MMTCO2e.

Under AB 32, the ARB published its Final Expanded List of Early Action Measures to Reduce Greenhouse Gas Emissions in California. Discrete early action measures are currently underway or are enforceable by January 1, 2010. The ARB has 44 early action measures that apply to the transportation, commercial, forestry, agriculture, cement, oil and gas, fire suppression, fuels, education, energy efficiency, electricity, and waste sectors. Of these early action measures, nine are considered discrete early action measures, as they are regulatory and enforceable by January 1, 2010. The ARB estimates that the 44 recommendations are expected to result in reductions of at least 42 MMTCO2e by 2020, representing approximately 25 percent of the 2020 target.

The ARB’s Climate Change Scoping Plan (Scoping Plan) contains measures designed to reduce the State’s emissions to 1990 levels by the year 2020 (California Air Resources Board 2008). The Scoping Plan identifies recommended measures for multiple greenhouse gas emission sectors and the associated emission reductions needed to achieve the year 2020 emissions target—each sector has a different emission reduction target. Most of the measures target the transportation and electricity sectors. As stated in the Scoping Plan, the key elements of the strategy for achieving the 2020 greenhouse gas target include:
• Expanding and strengthening existing energy efficiency programs as well as building and appliance standards;
• Achieving a statewide renewables energy mix of 33 percent; • Developing a California cap-and-trade program that links with other Western Climate Initiative partner programs to create a regional market system;
• Establishing targets for transportation-related greenhouse gas emissions for regions throughout California and pursuing policies and incentives to achieve those targets; • Adopting and implementing measures pursuant to existing State laws and policies, Including California’s clean car standards, goods movement measures, and the Low Carbon Fuel Standard; and Compton Residential Development
Air Quality and Greenhouse Gas Impact Study
City of Compton, CA Regulatory Framework and Background 18 • Creating targeted fees, including a public goods charge on water use, fees on high global warming potential gases, and a fee to fund the administrative costs of the State’s long-term commitment to AB 32 implementation.

In addition, the Scoping Plan differentiates between “capped” and “uncapped” strategies. “Capped” strategies are subject to the proposed cap-and-trade program. The Scoping Plan states that the inclusion of these emissions within the cap-and trade program will help ensure that the year 2020 emission targets are met despite some degree of uncertainty in the emission reduction estimates for any individual measure. Implementation of the capped strategies is calculated to achieve a sufficient amount of reductions by 2020 to achieve the emission target contained in AB 32. “Uncapped” strategies that will not be subject to the cap-and-trade emissions caps and requirements are provided as a margin of safety by accounting for additional greenhouse gas emission reductions.4 Senate Bill 100. Senate Bill 100 (SB 100) requires 100 percent of total retail sales of electricity in California to come from eligible renewable energy resources and zero-carbon resources by December 31, 2045. SB 100 was adopted September 2018.

The interim thresholds from prior Senate Bills and Executive Orders would also remain in effect. These include Senate Bill 1078 (SB 1078), which requires retail sellers of electricity, including investor-owned utilities and community choice aggregators, to provide at least 20 percent of their supply from renewable sources by 2017. Senate Bill 107 (SB 107) which changed the target date to 2010. Executive Order S-14- 08, which was signed on November 2008 and expanded the State’s Renewable Energy Standard to 33 percent renewable energy by 2020. Executive Order S-21-09 directed the CARB to adopt regulations by July 31, 2010 to enforce S-14-08. Senate Bill X1-2 codifies the 33 percent renewable energy requirement by 2020.

SB 375. Senate Bill 375 (SB 375) was adopted September 2008 and aligns regional transportation planning efforts, regional GHG emission reduction targets, and land use and housing allocation. SB 375 requires Metropolitan Planning Organizations (MPO) to adopt a sustainable communities strategy (SCS) or alternate planning strategy (APS) that will prescribe land use allocation in that MPOs Regional Transportation Plan (RTP). CARB, in consultation with each MPO, will provide each affected region with reduction targets for GHGs emitted by passenger cars and light trucks in the region for the years 2020 and 2035. These reduction targets will be updated every eight years but can be updated every four years if advancements in emissions technologies affect the reduction strategies to achieve the targets. CARB is also charged with reviewing each MPO’s sustainable communities strategy or alternate planning strategy for consistency with its assigned targets.

The proposed project is located within the Southern California Association of Governments (SCAG), which has authority to develop the SCS or APS. For the SCAG region, the targets set by CARB are at eight percent below 2005 per capita GHG emissions levels by 2020 and 13 percent below 2005 per capita GHG emissions levels by 2035. On April 4, 2012, SCAG adopted the 2012-2035 Regional Transportation Plan / Sustainable Communities Strategy (RTP/SCS), which meets the CARB emission reduction requirements.

The Housing Element Update is required by the State to be completed within 18 months after RTP/SCS adoption or by October 2013.

Compton Residential Development

City of Compton, CA Regulatory Framework and Background 19 City and County land use policies, including General Plans, are not required to be consistent with the RTP and associated SCS or APS. However, new provisions of CEQA would incentivize, through streamlining and other provisions, qualified projects that are consistent with an approved SCS or APS and categorized as “transit priority projects.”
Assembly Bill 939 and Senate Bill 1374. Assembly Bill 939 (AB 939) requires that each jurisdiction in California to divert at least 50 percent of its waste away from landfills, whether through waste reduction, recycling or other means. Senate Bill 1374 (SB 1374) requires the California Integrated Waste Management Board to adopt a model ordinance by March 1, 2004 suitable for adoption by any local agency to require 50 to 75 percent diversion of construction and demolition of waste materials from landfills.

Executive Order S-13-08. Executive Order S-13-08 indicates that “climate change in California during the next century is expected to shift precipitation patterns, accelerate sea level rise and increase temperatures, thereby posing a serious threat to California’s economy, to the health and welfare of its population and to its natural resources.” Pursuant to the requirements in the order, the 2009 California Climate Adaptation Strategy (California Natural Resource Agency 2009) was adopted, which is the “… first statewide, multi-sector, region-specific, and information-based climate change in California, identifying and exploring strategies to adapt to climate change, and specifying a direction for future research.

Executive Order B-30-15. Executive Order B-30-15, establishing a new interim statewide greenhouse gas emission reduction target to reduce greenhouse gas emissions to 40 percent below 1990 levels by 2030, was signed by Governor Brown in April 2015.

Executive Order B-29-15. Executive Order B-29-15, mandates a statewide 25% reduction in potable water usage and was signed into law on April 1, 2015.

Executive Order B-37-16. Executive Order B-37-16, continuing the State’s adopted water reduction, was signed into law on May 9, 2016. The water reduction builds off the mandatory 25% reduction called for in EO B-29-15.

2.2.4 South Coast Air Quality Management District
The Project is within the South Coast Air Basin, which is under the jurisdiction of the South Coast Air Quality Management District (SCAQMD). SCAQMD Regulation XXVII currently includes three rules:
• The purpose of Rule 2700 is to define terms and post global warming potentials. • The purpose of Rule 2701, SoCal Climate Solutions Exchange, is to establish a voluntary program to encourage, quantify, and certify voluntary, high quality certified greenhouse gas emission reductions in the SCAQMD.
• Rule 2702, Greenhouse Gas Reduction Program, was adopted on February 6, 2009. The purpose of this rule is to create a Greenhouse Gas Reduction Program for greenhouse gas emission reductions Compton Residential Development

City of Compton, CA Regulatory Framework and Background 20 in the SCAQMD. The SCAQMD will fund projects through contracts in response to requests for proposals or purchase reductions from other parties.

SCAQMD Threshold Development
The SCAQMD has established recommended significance thresholds for greenhouse gases for local lead agency consideration (“SCAQMD draft local agency threshold”). SCAQMD has published a five-tiered draft GHG threshold which includes a 10,000 metric ton of CO2e per year for stationary/industrial sources and 3,000 metric tons of CO2e per year significance threshold for residential/commercial projects (South Coast Air Quality Management District 2010c). Tier 3 is anticipated to be the primary tier by which the SCAQMD will determine significance for projects. The Tier 3 screening level for stationary sources is based on an emission capture rate of 90 percent for all new or modified projects. A 90-precent emission capture rate means that 90 percent of total emissions from all new or modified stationary source projects would be subject to CEQA analysis. The 90-percent capture rate GHG significance screening level in Tier 3 for stationary sources was derived using the SCAQMD’s annual Emissions Reporting Program.

The current draft thresholds consist of the following tiered approach:
• Tier 1 consists of evaluating whether or not the project qualifies for any applicable exemption under CEQA.
• Tier 2 consists of determining whether or not the project is consistent with a greenhouse gas reduction plan. If a project is consistent with a qualifying local greenhouse gas reduction plan, it does not have significant greenhouse gas emissions.
• Tier 3 consists of screening values, which the lead agency can choose but must be consistent. A project’s construction emissions are averaged over 30 years and are added to a project’s operational emissions. If a project’s emissions are under one of the following screening thresholds, then the project is less than significant:
- All land use types: 3,000 MTCO2e per year
- Based on land use types: residential is 3,500 MTCO2e per year; commercial is 1,400 MTCO2e per year; and mixed use is 3,000 MTCO2e per year
• Tier 4 has the following options:
- Option 1: Reduce emissions from business as usual by a certain percentage; this percentage is currently undefined
- Option 2: Early implementation of applicable AB 32 Scoping Plan measures - Option 3: Year 2020 target for service populations (SP), which includes residents and employees:

4.8 MTCO2e/SP/year for projects and 6.6 MTCO2e/SP/year for plans; - Option 3, 2035 target: 3.0 MTCO2e/SP/year for projects and 4.1 MTCO2e/SP/year for plans • Tier 5 involves mitigation offsets to achieve target significance threshold.

2.2.5 City of Compton
City of Compton General Plan
Compton Residential Development
Air Quality and Greenhouse Gas Impact Study
City of Compton, CA Regulatory Framework and Background 21 Local jurisdictions, such as the City of Compton, have the authority and responsibility to reduce air pollution through its police power and decision-making authority. Specifically, the City is responsible for the assessment and mitigation of air emissions resulting from its land use decisions. The City is also responsible for the implementation of transportation control measures as outlined in the 2016 AQMP.

Examples of such measures include bus turnouts, energy-efficient streetlights, and synchronized traffic signals. In accordance with CEQA requirements and the CEQA review process, the City assesses the air quality impacts of new development projects, requires mitigation of potentially significant air quality impacts by conditioning discretionary permits, and monitors and enforces implementation of such mitigation.

In accordance with the CEQA requirements, the City does not, however, have the expertise to develop plans, programs, procedures, and methodologies to ensure that air quality within the City and region will meet federal and state standards. Instead, the City relies on the expertise of the SCAQMD and utilizes the SCAQMD CEQA Handbook as the guidance document for the environmental review of plans and development proposals within its jurisdiction.

The Draft Compton General Plan 2030 Air Quality Element, contains the following air quality-related goals and policies that are applicable to the proposed project:

Goal 1 Reduce automobile use.

Policies

1.2 The City of Compton will implement programs that reduce automobile use by City residents.

1.4 The City of Compton will increase ridership on the local transit system by making it more user-friendly by providing safe, attractive places to wait that include route maps.

Goal 2 Reduce peak-hour roadway congestion.

Goal 3 Reduce emissions associated with vehicle miles traveled by providing a balance of jobs and housing.

Goal 4 Reduce emissions associated with energy consumption.

Policies

4.2 The City of Compton will encourage incorporation of energy features, including passive solar, in the construction and rehabilitation of new and existing structures.

4.3 The City of Compton will support recycling programs which reduce emissions associated with manufacturing and waste disposal.

5.5 The City of Compton will reduce the exposure of sensitive receptors to dust and odors to the maximum extent feasible.

City of Compton Climate Action Plan
The City of Compton does not currently have a Climate Action Plan.

Therefore, to determine whether the project's GHG emissions are significant, this analysis uses the SCAQMD draft local agency tier 3 screening threshold of 3,000 MTCO2e per year for all land use types.

The project will be subject to the latest requirements of the California Green Building and Title 24 Energy Efficiency Standards (currently 2019) which would reduce project-related greenhouse gas emissions.

23 3.0 Setting

3.1 Existing Physical Setting
The project site is located in the City of Compton, which is part of the South Coast Air Basin (SCAB) that includes all of Orange County as well as the non-desert portions of Los Angeles, Riverside, and San Bernardino Counties. The South Coast Air Basin islocated on a coastal plain with connecting broad valleys and low hills to the east. Regionally, the South Coast Air Basin is bounded by the Pacific Ocean to the southwest and high mountains to the east forming the inland perimeter.

3.1.1 Local Climate and Meteorology
Dominant airflows provide the driving mechanism for transport and dispersion of air pollution. The mountains surrounding the region form natural horizontal barriers to the dispersion of air contaminants.

Air pollution created in the coastal areas and around the Los Angeles area is transported inland until it reaches the mountains where the combination of mountains and inversion layers generally prevent further dispersion. This poor ventilation results in a gradual degradation of air quality from the coastal areas to inland areas. Air stagnation may occur during the early evening and early morning periods of transition between day and nighttime flows. The region also experiences periods of hot, dry winds from the desert, known as Santa Ana winds. If the Santa Ana winds are strong, they can surpass the sea breeze, which blows from the ocean to the land, and carry the suspended dust and pollutants out to the ocean. If the winds are weak, they are opposed by the sea breeze and cause stagnation, resulting in high pollution events.

The annual average temperature varies little throughout much of the basin, ranging from the low to middle 60s, measured in degrees Fahrenheit (°F). With more pronounced oceanic influence, coastal areas show less variability in annual minimum and maximum temperatures than inland areas where the project site is located. The majority of the annual rainfall in the basin occurs between November and April. Summer rainfall is minimal and is generally limited to scattered thunderstorms in the coastal regions and slightly heavier showers in the eastern portion of the basin along the coastal side of the mountains. Year-to-year patterns in rainfall are unpredictable because of fluctuations in the weather.

Temperature inversions limit the vertical depth through which pollution can be mixed. Among the most common temperature inversions in the basin are radiation inversions, which form on clear winter nights when cold air off mountains sink to the valley floor while the air aloft over the valley remains warm.

These inversions, in conjunction with calm winds, trap pollutants near the source. Other types of temperature inversions that affect the basin include marine, subsidence, and high-pressure inversions.

Summers are often periods of hazy visibility and occasionally unhealthful air. Strong temperature inversions may occur that limit the vertical depth through which air pollution can be dispersed. Air pollutants concentrate because they cannot rise through the inversion layer and disperse. These inversions are more common and persistent during the summer months. Over time, sunlight produces photochemical reactions within this inversion layer that creates ozone, a particularly harmful air pollutant. Occasionally, strong thermal convections occur which allows the air pollutants to rise high Compton Residential Development

24 enough to pass over the mountains and ultimately dilute the smog cloudtrap pollutants such as automobile exhaust near their source. While these inversions may lead to air pollution “hot spots” in heavily developed coastal areas of the basin, there is not enough traffic in inland valleys to cause any winter air pollution problems. Despite light wind conditions, especially at night and in the early morning, winter is generally a period of good air quality in the project vicinity.

In the winter, light nocturnal winds result mainly from the drainage of cool air off of the mountains toward the valley floor while the air aloft over the valley remains warm. This forms a type of inversion known as a radiation inversion. Such winds are characterized by stagnation and poor local mixing and trap pollutants such as automobile exhaust near their source. While these inversions may lead to air pollution “hot spots” in heavily developed coastal areas of the basin, there is not enough traffic to cause any winter air pollution problems. Despite light wind conditions, especially at night and in the early morning, winter is generally a period of good air quality in the project vicinity.

The temperature and precipitation levels for the City of Torrance, closest monitoring station to the project site, are in Table 3. Table 3 shows that August is typically the warmest month and January and December are typically the coolest months. Rainfall in the project area varies considerably in both time and space. Almost all the annual rainfall comes from the fringes of mid-latitude storms from late November to early April, with summers being almost completely dry.

The next nearest monitoring station to the project site is the Long Beach-2425 Webster Street Station (Long Beach Station). The Long Beach Station is located approximately 6.56 miles southeast of the project site. The Long Beach Station was used to provide the existing PM2.5 levels. Additional data was also pulled from the SCAQMD historical data for the South Central LA County (Area 12) for both sulfur dioxide and carbon monoxide to provide the existing levels. Table 4 presents the monitored pollutant levels within the vicinity. However, it should be noted that due to the air monitoring station distance from the project site, recorded air pollution levels at the air monitoring station reflect with varying degrees of accuracy, local air quality conditions at the project site.

The monitoring data presented in Table 4 shows that ozone and particulate matter (PM10 and PM2.5) are the air pollutants of primary concern in the project area, which are detailed below.

Ozone
During the 2017 to 2019 monitoring period, the State 1-hour concentration standard for ozone has been exceeded for one day in 2019 at the Compton Station. Both the Federal and the State 8-hour ozone standard (0.07 ppm) have been exceeded between one and five days each year over the past three years at the Compton Station.

Ozone is a secondary pollutant as it is not directly emitted. Ozone is the result of chemical reactions between other pollutants, most importantly hydrocarbons and NO2, which occur only in the presence of bright sunlight. Pollutants emitted from upwind cities react during transport downwind to produce the oxidant concentrations experienced in the area. Many areas of the SCAQMD contribute to the ozone levels experienced at the monitoring station, with the more significant areas being those directly upwind.

Carbon Monoxide
CO is another important pollutant that is due mainly to motor vehicles. The South Central LA County Area did not record an exceedance of the state or federal 1-hour or 8-hour CO standards for the last three years.

Nitrogen Dioxide
The Compton Station did not record an exceedance of the State or Federal NO2 standards for the last three years.

Sulfur Dioxide
The South Central LA County Area did not record an exceedance of the State SO2 standards for the last three years.

Particulate Matter
During the 2017 to 2019 monitoring period, the State 24-hour concentration standard for PM10 was exceeded between four and ten days each year at the Long Beach Station. Over the same time period the Federal 24-hour and Federal annual standards for PM10 have not been exceeded at the Long Beach Station.

The Federal 24-hour standard for PM2.5 was exceeded between one and five days each year during the 2017 to 2019 monitoring period at the Compton Station.

According to the EPA, some people are much more sensitive than others to breathing fine particles (PM10 and PM2.5). People with influenza, chronic respiratory and cardiovascular diseases, and the elderly may suffer worsening illness and premature death due to breathing these fine particles. People with bronchitis can expect aggravated symptoms from breathing in fine particles. Children may Compton Residential Development

27 experience decline in lung function due to breathing in PM10 and PM2.5. Other groups considered sensitive are smokers and people who cannot breathe well through their noses. Exercising athletes are also considered sensitive, because many breathe through their mouths during exercise.

3.1.3 Attainment Status
The EPA and the ARB designate air basins where ambient air quality standards are exceeded as “nonattainment” areas. If standards are met, the area is designated as an “attainment” area. If there is inadequate or inconclusive data to make a definitive attainment designation, they are considered “unclassified.” National nonattainment areas are further designated as marginal, moderate, serious, severe, or extreme as a function of deviation from standards. Each standard has a different definition, or ‘form’ of what constitutes attainment, based on specific air quality statistics. For example, the Federal 8-hour CO standard is not to be exceeded more than once per year; therefore, an area is in attainment of the CO standard if no more than one 8-hour ambient air monitoring values exceeds the threshold per year. In contrast, the federal annual PM2.5 standard is met if the three-year average of the annual average PM2.5 concentration is less than or equal to the standard. Table 5 lists the attainment status for the criteria pollutants in the basin.

3.2 Greenhouse Gases
Constituent gases of the Earth’s atmosphere, called atmospheric greenhouse gases (GHG), play a critical role in the Earth’s radiation amount by trapping infrared radiation emitted from the Earth’s surface, which otherwise would have escaped to space. Prominent greenhouse gases contributing to this process include carbon dioxide (CO2), methane (CH4), ozone, water vapor, nitrous oxide (N2O), and chlorofluorocarbons (CFCs). This phenomenon, known as the Greenhouse Effect, is responsible for maintaining a habitable climate. Anthropogenic (caused or produced by humans) emissions of these greenhouse gases in excess of natural ambient concentrations are responsible for the enhancement of the Greenhouse Effect and have led to a trend of unnatural warming of the Earth’s natural climate, known as global warming or climate change. Emissions of gases that induce global warming are attributable to human activities associated with industrial/manufacturing, agriculture, utilities, transportation, and residential land uses. Transportation is responsible for 41 percent of the State’s greenhouse gas emissions, followed by electricity generation. Emissions of CO2 and nitrous oxide (NO2) are byproducts of fossil fuel combustion. Methane, a potent greenhouse gas, results from off-gassing associated with agricultural practices and landfills. Sinks of CO2, where CO2 is stored outside of the atmosphere, include uptake by vegetation and dissolution into the ocean. Table 6 provides a description of each of the greenhouse gases and their global warming potential.

30 Table 6: Description of Greenhouse Gases
Greenhouse Gas Description and Physical Properties Sources Nitrous oxide
Nitrous oxide (N20),also known as laughing gas is a
colorless gas. It has a lifetime of 114 years. Its global warming potential is 298.

Microbial processes in soil and water,
fuel combustion, and industrial
processes. In addition to agricultural
sources, some industrial processes
(nylon production, nitric acid
production) also emit N20.

Methane
Methane (CH4) is a flammable gas and is the main
component of natural gas. It has a lifetime of 12 years.

Its global warming potential is 25.

A natural source of CH4 is from the
decay of organic matter. Methane is
extracted from geological deposits
(natural gas fields). Other sources are
from the decay of organic material in
landfills, fermentation of manure, and
cattle farming.

Carbon dioxide
Carbon dioxide (CO2) is an odorless, colorless, natural greenhouse gas. Carbon dioxide’s global warming
potential is 1. The concentration in 2005 was 379 parts per million (ppm), which is an increase of about 1.4
ppm per year since 1960.

Natural sources include decomposition
of dead organic matter; respiration of
bacteria, plants, animals, and fungus;
evaporation from oceans; and volcanic
outgassing. Anthropogenic sources are
from burning coal, oil, natural gas, and
wood.

Chlorofluorocarbons
CFCs are nontoxic, nonflammable, insoluble, and
chemically unreactive in the troposphere (the level of
air at the earth’s surface). They are gases formed
synthetically by replacing all hydrogen atoms in
methane or methane with chlorine and/or fluorine
atoms. Global warming potentials range from 3,800 to
8,100.

Chlorofluorocarbons were synthesized
in 1928 for use as refrigerants, aerosol
propellants, and cleaning solvents. They
destroy stratospheric ozone, therefore
their production was stopped as
required by the Montreal Protocol.

Hydrofluorocarbons
Hydrofluorocarbons (HFCs) are a group of greenhouse
gases containing carbon, chlorine, and at least one
hydrogen atom. Global warming potentials range from
140 to 11,700.

Hydrofluorocarbons are synthetic
manmade chemicals used as a
substitute for chlorofluorocarbons in
applications such as automobile air
conditioners and refrigerants.

Perfluorocarbons
Perfluorocarbons (PFCs) have stable molecular
structures and only break down by ultraviolet rays
about 60 kilometers above the Earth's surface. They
have a lifetime 10,000 to 50,000 years. They have a
global warming potential range of 6,200 to 9,500.

Two main sources of perfluorocarbons
are primary aluminum production and
semiconductor manufacturing.

Sulfur
hexafluoride
Sulfur hexafluoride (SF6) is an inorganic, odorless,
colorless, and nontoxic, nonflammable gas. It has a
lifetime of 3,200 years. It has a high global warming
potential, 23,900.

This gas is manmade and used for
insulation in electric power
transmission equipment, in the
magnesium industry, in semiconductor
manufacturing, and as a tracer gas for
leak detection.

City of Compton, CA Modeling Parameters and Assumptions 31 4.0 Modeling Parameters and Assumptions

4.1 Construction
Typical emission rates from construction activities were obtained from CalEEMod Version 2016.3.2 CalEEMod is a computer model published by the SCAQMD for estimating air pollutant emissions. The CalEEMod program uses the EMFAC2014 computer program to calculate the emission rates specific for the southern portion of Los Angeles County for construction-related employee vehicle trips and the OFFROAD2011 computer program to calculate emission rates for heavy truck operations. EMFAC2014 and OFFROAD2011 are computer programs generated by CARB that calculates composite emission rates for vehicles. Emission rates are reported by the program in grams per trip and grams per mile or grams per running hour. Using CalEEMod, the peak daily air pollutant emissions were calculated and presented below. These emissions represent the highest level of emissions for each of the construction phases in terms of air pollutant emissions.

The analysis assesses the emissions associated with the construction of the proposed project as indicated in Table 1. Construction is anticipated to begin early 2022 and be completed by late 2023; therefore, construction was estimated to start no sooner than January 2022 and end by mid-December 2023. The phases of the construction activities which have been analyzed below are: 1) grading, 2) building, 3) paving, and 4) architectural coating. For details on construction modeling and construction equipment for each phase, please see Appendix A.

The project will be required to comply with existing SCAQMD rules for the reduction of fugitive dust emissions. SCAQMD Rule 403 establishes these procedures. Compliance with this rule is achieved through application of standard best management practices in construction and operation activities, such as application of water or chemical stabilizers to disturbed soils, managing haul road dust by application of water, covering haul vehicles, restricting vehicle speeds on unpaved roads to 15 mph, sweeping loose dirt from paved site access roadways, cessation of construction activity when winds exceed 25 mph and establishing a permanent, stabilizing ground cover on finished sites. In addition, projects that disturb 50 acres or more of soil or move 5,000 cubic yards of materials per day are required to submit a Fugitive Dust Control Plan or a Large Operation Notification Form to SCAQMD. Based on the size of the Project area (approximately 2.45 acres) and the fact that the project won’t export more than 5,000 cubic yards of material a day a Fugitive Dust Control Plan or Large Operation Notification would not be required.

SCAQMD’s Rule 403 minimum requirements require that the application of the best available dust control measures are used for all grading operations and include the application of water or other soil stabilizers in sufficient quantity to prevent the generation of visible dust plumes. Compliance with Rule 403 would require the use of water trucks during all phases where earth moving operations would occur.

Compliance with Rule 403 is required.

Compton Residential Development
Air Quality and Greenhouse Gas Impact Study
City of Compton, CA Modeling Parameters and Assumptions 32 4.2 Operations
Operational or long-term emissions occur over the life of the Project. Both mobile and area sources generate operational emissions. Area source emissions arise from consumer product usage, heaters that consume natural gas, gasoline-powered landscape equipment, and architectural coatings (painting).

Mobile source emissions from motor vehicles are the largest single long-term source of air pollutants from the operation of the Project. Small amounts of emissions would also occur from area sources such as the consumption of natural gas for heating, hearths, from landscaping emissions, and consumer product usage. The operational emissions were estimated using the latest version of CalEEMod.

Mobile Sources
Mobile sources include emissions from the additional vehicle miles generated from the proposed project. The vehicle trips associated with the proposed project are based upon the trip generation rates given in the project-specific traffic and parking analysis (TJW Engineering, Inc.) which uses the ITE 10th Trip Generation Manual. The traffic and parking analysis shows a trip generation rate of 7.32 trips per dwelling unit.

The program then applies the emission factors for each trip which is provided by the EMFAC2014 model to determine the vehicular traffic pollutant emissions. The CalEEMod default trip lengths were used in this analysis. Please see CalEEMod output comments sections in Appendix A and B for details.

Area Sources
Area sources include emissions from consumer products, landscape equipment and architectural coatings. Landscape maintenance includes fuel combustion emissions from equipment such as lawn mowers, rototillers, shredders/grinders, blowers, trimmers, chain saws, and hedge trimmers, as well as air compressors, generators, and pumps. As specifics were not known about the landscaping equipment fleet, CalEEMod defaults were used to estimate emissions from landscaping equipment.

Per SCAQMD Rule 1113 as amended on June 3, 2011, the architectural coatings that would be applied after January 1, 2014 will be limited to an average of 50 grams per liter or less and the CalEEMod model default was utilized.

Energy Usage
2016.3.2 CalEEMod defaults were utilized.

4.3 Localized Construction Analysis
The SCAQMD has published a “Fact Sheet for Applying CalEEMod to Localized Significance Thresholds” (South Coast Air Quality Management District 2011b). CalEEMod calculates construction emissions based on the number of equipment hours and the maximum daily disturbance activity possible for each piece of equipment. In order to compare CalEEMod reported emissions against the localized significance threshold lookup tables, the CEQA document should contain in its project design features or its mitigation measures the following parameters:

The local air quality emissions from construction were analyzed using the SCAQMD’s Mass Rate Localized Significant Threshold Look-up Tables and the methodology described in Localized Significance Threshold Methodology, prepared by SCAQMD, revised July 2008. The Look-up Tables were developed by the SCAQMD in order to readily determine if the daily emissions of CO, NOx, PM10, and PM2.5 from the proposed project could result in a significant impact to the local air quality. The emission thresholds were based on the South Central Los Angeles County source receptor area (SRA 12) and a disturbance of 2 acres per day at a distance of 25 meters (82 feet). According to LST methodology, any receptor located closer than 25 meters should be based on the 25 meter threshold. The closest receptors are the multiplefamily residential land uses located approximately 35 feet (~11 meters) southeast and 50 feet (~15 meters) east of the project site and the single-family residential land uses located approximately 50 feet (~15 meters) south of the project site.

4.4 Localized Operational Analysis
According to SCAQMD LST methodology, LSTs would apply to the operational phase of a project, if the project includes stationary sources, or attracts mobile sources (such as heavy-duty trucks) that may spend long periods queuing and idling at the site; such as industrial warehouse/transfer facilities. The proposed project is a residential project and does not include such uses. Therefore, due to the lack of stationary source emissions, no long-term localized significance threshold analysis is warranted.

Compton Residential Development
Air Quality and Greenhouse Gas Impact Study
City of Compton, CA Thresholds of Significance
34 5.0 Thresholds of Significance

5.1 Air Quality Thresholds of Significance

5.1.1 CEQA Guidelines for Air Quality
The CEQA Guidelines define a significant effect on the environment as “a substantial, or potentially substantial, adverse change in the environment.” To determine if a project would have a significant impact on air quality, the type, level, and impact of emissions generated by the project must be evaluated.

The following air quality significance thresholds are contained in Appendix G of the CEQA Guidelines. A significant impact would occur if the project would:
a) Conflict with or obstruct implementation of the applicable air quality plan; b) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is nonattainment under an applicable national or state ambient air quality standard; c) Expose sensitive receptors to substantial pollutant concentrations; or d) Result in other emissions (such as those leading to odors) adversely affecting a substantial number of people.

While the final determination of whether a project is significant is within the purview of the Lead Agency pursuant to Section 15064(b) of the CEQA Guidelines, SCAQMD recommends that its quantitative air pollution thresholds be used to determine the significance of project emissions. If the Lead Agency finds that the project has the potential to exceed these air pollution thresholds, the project should be considered to have significant air quality impacts. There are daily emission thresholds for construction and operation of a proposed project in the basin.

5.1.2 Regional Significance Thresholds for Construction Emissions The following CEQA significance thresholds for construction emissions are established for the Basin:
• 75 pounds per day (lbs/day) of VOC
• 100 lbs/day of NOx
• 550 lbs/day of CO
• 150 lbs/day of PM10
• 55 lbs/day of PM2.5
• 150 lbs/day of SO2
Projects in the basin with construction-related emissions that exceed any of the emission thresholds are considered to be significant under SCAQMD guidelines.

5.1.3 Regional Significance Thresholds for Operational Emissions The daily operational emissions significance thresholds for the basin are as follows:

Compton Residential Development
Air Quality and Greenhouse Gas Impact Study
City of Compton, CA Thresholds of Significance
35 • 55 pounds per day (lbs/day) of VOC
• 55 lbs/day of NOx
• 550 lbs/day of CO
• 150 lbs/day of PM10
• 55 lbs/day of PM2.5
• 150 lbs/day of SO2
Local Microscale Concentration Standards The significance of localized project impacts under CEQA depends on whether ambient CO levels in the vicinity of the project are above or below State and federal CO standards. If ambient levels are below the standards, a project is considered to have a significant impact if project emissions result in an exceedance of one or more of these standards. If ambient levels already exceed a State or federal standard, project emissions are considered significant if they increase 1-hour CO concentrations by 1.0 ppm or more or 8-hour CO concentrations by 0.45 ppm or more. The following are applicable local emission concentration standards for CO:
• California State 1-hour CO standard of 20.0 ppm
• California State 8-hour CO standard of 9.0 ppm

5.1.4 Thresholds for Localized Significance
Project-related construction air emissions may have the potential to exceed the State and Federal air quality standards in the project vicinity, even though these pollutant emissions may not be significant enough to create a regional impact to the South Coast Air Basin. In order to assess local air quality impacts the SCAQMD has developed Localized Significant Thresholds (LSTs) to assess the project-related air emissions in the project vicinity. The SCAQMD has also provided Final Localized Significant Threshold Methodology (LST Methodology), June 2003, which details the methodology to analyze local air emission impacts. The Localized Significant Threshold Methodology found that the primary emissions of concern are NO2, CO, PM10, and PM2.5.

The emission thresholds were calculated based on the South Central Los Angeles County source receptor area (SRA 12) and a disturbance of 2 acres per day at a distance of 25 meters (82 feet), for construction.

5.2 Greenhouse Gas Thresholds of Significance

5.2.1 CEQA Guidelines for Greenhouse Gas
CEQA Guidelines define a significant effect on the environment as “a substantial, or potentially substantial, adverse change in the environment.” To determine if a project would have a significant impact on greenhouse gases, the type, level, and impact of emissions generated by the project must be evaluated.

The following greenhouse gas significance thresholds are contained in Appendix G of the CEQA Guidelines, which were amendments adopted into the Guidelines on March 18, 2010, pursuant to SB 97. A significant impact would occur if the project would:
(a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment; or
Compton Residential Development
Air Quality and Greenhouse Gas Impact Study
City of Compton, CA Thresholds of Significance
36 (b) Conflict with any applicable plan, policy or regulation of an agency adopted for the purpose of reducing the emissions of greenhouse gases.

However, despite this, currently neither the CEQA statutes, OPR guidelines, nor the draft proposed changes to the CEQA Guidelines prescribe thresholds of significance or a particular methodology for performing an impact analysis; as with most environmental topics, significance criteria are left to the judgment and discretion of the Lead Agency. As previously discussed (Section 2.2.4 of this report), SCAQMD has drafted interim thresholds. The screening threshold of 3,000 MTCO2e per year for all land uses was used in this analysis.

37 6.0 Air Quality Emissions Impact

6.1 Construction Air Quality Emissions Impact
The latest version of CalEEMod was used to estimate the onsite and offsite construction emissions. The emissions incorporate Rule 402 and 403. Rule 402 and 403 (fugitive dust) are not considered mitigation measures as the project by default is required to incorporate these rules during construction.

6.1.1 Regional Construction Emissions
The construction emissions for the project would not exceed the SCAQMD’s daily emission thresholds at the regional level as demonstrated in Table 8, and therefore would be considered less than significant.

Notes:
1 Source: Calculated from CalEEMod and SCAQMD’s Mass Rate Look-up Tables for two acres in South Central Los Angeles County Source Receptor Area (SRA 12). Project will disturb a maximum of 2 acres per day (see Table 7). 2 The nearest sensitive receptors are the multiple-family residential land uses located approximately 35 feet (~11 meters) southeast and 50 feet (~15 meters) east of the project site and the single-family residential land uses located approximately 50 feet (~15 meters) south of the project site; however, according to LST methodology any receptor located closer than 25 meters should be based on the 25 meter threshold.

6.1.3 Odors
Potential sources that may emit odors during construction activities include the application of materials such as asphalt pavement. The objectionable odors that may be produced during the construction process are of short-term in nature and the odor emissions are expected cease upon the drying or hardening of the odor producing materials. Diesel exhaust and VOCs would be emitted during construction of the project, which are objectionable to some; however, emissions would disperse rapidly from the project site and therefore should not reach an objectionable level at the nearest sensitive receptors. Due to the short-term nature and limited amounts of odor producing materials being utilized, no significant impact related to odors would occur during construction of the proposed project.

The SCAQMD recommends that odor impacts be addressed in a qualitative manner. Such an analysis shall determine whether the project would result in excessive nuisance odors, as defined under the California Code of Regulations and Section 41700 of the California Health and Safety Code, and thus would constitute a public nuisance related to air quality.

Potential sources that may emit odors during the on-going operations of the proposed project would include odor emissions from trash storage areas. Due to the distance of the nearest receptors from the project site and through compliance with SCAQMD’s Rule 402 no significant impact related to odors would occur during the on-going operations of the proposed project.

6.1.4 Construction-Related Toxic Air Contaminant Impact The greatest potential for toxic air contaminant emissions would be related to diesel particulate emissions associated with heavy equipment operations during construction of the proposed project. The Office of Environmental Health Hazard Assessment (OEHHA) has issued the Air Toxic Hot Spots Program Risk Assessment Guidelines and Guidance Manual for the Preparation of Health Risk Assessments, February 2015 to provide a description of the algorithms, recommended exposure variates, cancer and noncancer health values, and the air modeling protocols needed to perform a health risk assessment Compton Residential Development

39 (HRA) under the Air Toxics Hot Spots Information and Assessment Act of 1987. Hazard identification includes identifying all substances that are evaluated for cancer risk and/or non-cancer acute, 8-hour, and chronic health impacts. In addition, identifying any multi-pathway substances that present a cancer risk or chronic non-cancer hazard via non-inhalation routes of exposure.

Given the relatively limited number of heavy-duty construction equipment and construction schedule, the proposed project would not result in a long-term substantial source of toxic air containment emissions and corresponding individual cancer risk. Furthermore, construction-based particulate matter (PM) emissions (including diesel exhaust emissions) do not exceed any local or regional thresholds.

Therefore, no significant short-term toxic air contaminant impacts would occur during construction of the proposed project.

6.2 Operational Air Quality Emissions Impact

6.2.1 Regional Operational Emissions
The operations-related criteria air quality impacts created by the proposed project have been analyzed through the use of CalEEMod model. The operating emissions were based on year 2023, which is the anticipated opening year for the project. The summer and winter emissions created by the proposed project’s long-term operations were calculated and the highest emissions from either summer or winter are summarized in Table 10.

2 Area sources consist of emissions from consumer products, architectural coatings, and landscaping equipment. 3 Energy usage consists of emissions from on-site natural gas usage. 4 Mobile sources consist of emissions from vehicles and road dust.

Table 10 provides the project's unmitigated operational emissions. Table 10 shows that the project does not exceed the SCAQMD daily emission threshold and regional operational emissions are considered to be less than significant.

6.2.2 Localized Operational Emissions
Project-related air emissions from on-site sources such as architectural coatings, landscaping equipment, on-site usage of natural gas appliances as well as the operation of vehicles on-site may have the potential Compton Residential Development
Air Quality and Greenhouse Gas Impact Study
City of Compton, CA Air Quality Emissions Impact
40 to exceed the State and Federal air quality standards in the project vicinity, even though these pollutant emissions may not be significant enough to create a regional impact to the Air Basin.

As stated previously, according to SCAQMD LST methodology, LSTs would apply to the operational phase of a project, if the project includes stationary sources, or attracts mobile sources (such as heavy-duty trucks) that may spend long periods queuing and idling at the site; such as industrial warehouse/transfer facilities. The proposed project is a residential project and does not include such uses. Therefore, due to the lack of stationary source emissions, no long-term localized significance threshold analysis is warranted.

6.3 CO Hot Spot Emissions
CO is the pollutant of major concern along roadways because the most notable source of CO is motor vehicles. For this reason, CO concentrations are usually indicative of the local air quality generated by a roadway network and are used as an indicator of potential local air quality impacts. Local air quality impacts can be assessed by comparing future without and with project CO levels to the State and Federal CO standards which were presented in above in Section 5.0.

To determine if the proposed project could cause emission levels in excess of the CO standards discussed above in Section 5.0, a sensitivity analysis is typically conducted to determine the potential for CO “hot spots” at a number of intersections in the general project vicinity. Because of reduced speeds and vehicle queuing, “hot spots” potentially can occur at high traffic volume intersections with a Level of Service E or worse.

Micro-scale air quality emissions have traditionally been analyzed in environmental documents where the air basin was a non-attainment area for CO. However, the SCAQMD has demonstrated in the CO attainment redesignation request to EPA that there are no “hot spots” anywhere in the air basin, even at intersections with much higher volumes, much worse congestion, and much higher background CO levels than anywhere in Riverside County. If the worst-case intersections in the air basin have no “hot spot” potential, any local impacts will be below thresholds.

The project-specific traffic and parking analysis (TJW Engineering, Inc.) showed that the project would generate a maximum of approximately 439 vehicle trips per day. The 1992 Federal Attainment Plan for Carbon Monoxide (1992 CO Plan) showed that an intersection which has a daily traffic volume of approximately 100,000 vehicles per day would not violate the CO standard. Therefore, as the project only includes a maximum of 439 daily vehicle trips, no CO “hot spot” modeling was performed and no significant long-term air quality impact is anticipated to local air quality with the on-going use of the proposed project.

6.4 Cumulative Regional Air Quality Impacts
Cumulative projects include local development as well as general growth within the project area.

However, as with most development, the greatest source of emissions is from mobile sources, which travel well out of the local area. Therefore, from an air quality standpoint, the cumulative analysis would Compton Residential Development
Air Quality and Greenhouse Gas Impact Study
City of Compton, CA Air Quality Emissions Impact
41 extend beyond any local projects and when wind patterns are considered, would cover an even larger area. Accordingly, the cumulative analysis for the project’s air quality must be generic by nature.

The project area is out of attainment for both ozone and PM10 particulate matter. Construction and operation of cumulative projects will further degrade the local air quality, as well as the air quality of the South Coast Air Basin. The greatest cumulative impact on the quality of regional air cell will be the incremental addition of pollutants mainly from increased traffic from residential, commercial, and industrial development and the use of heavy equipment and trucks associated with the construction of these projects. Air quality will be temporarily degraded during construction activities that occur separately or simultaneously. However, in accordance with the SCAQMD methodology, projects that do not exceed the SCAQMD criteria or can be mitigated to less than criteria levels are not significant and do not add to the overall cumulative impact. The project does not exceed any of the thresholds of significance and therefore is considered less than significant.

6.5 Air Quality Compliance
The California Environmental Quality Act (CEQA) requires a discussion of any inconsistencies between a proposed project and applicable General Plans and Regional Plans (CEQA Guidelines Section 15125). The regional plan that applies to the proposed project includes the SCAQMD Air Quality Management Plan (AQMP). Therefore, this section discusses any potential inconsistencies of the proposed project with the AQMP.

The purpose of this discussion is to set forth the issues regarding consistency with the assumptions and objectives of the AQMP and discuss whether the proposed project would interfere with the region’s ability to comply with Federal and State air quality standards. If the decision-makers determine that the proposed project is inconsistent, the lead agency may consider project modifications or inclusion of mitigation to eliminate the inconsistency.

The SCAQMD CEQA Handbook states that "New or amended General Plan Elements (including land use zoning and density amendments), Specific Plans, and significant projects must be analyzed for consistency with the AQMP." Strict consistency with all aspects of the plan is usually not required A proposed project should be considered to be consistent with the AQMP if it furthers one or more policies and does not obstruct other policies. The SCAQMD CEQA Handbook identifies two key indicators of consistency:
(1) Whether the project will result in an increase in the frequency or severity of existing air quality violations or cause or contribute to new violations, or delay timely attainment of air quality standards or the interim emission reductions specified in the AQMP. (2) Whether the project will exceed the assumptions in the AQMP in 2016 or increments based on the year of project buildout and phase.

Both of these criteria are evaluated in the following sections.

A. Criterion 1 - Increase in the Frequency or Severity of Violations Compton Residential Development
Air Quality and Greenhouse Gas Impact Study
City of Compton, CA Air Quality Emissions Impact
42 Based on the air quality modeling analysis contained in this Air Analysis, neither short-term construction impacts, nor long-term operations will result in significant impacts based on the SCAQMD regional and local thresholds of significance.

Therefore, the proposed project is not projected to contribute to the exceedance of any air pollutant concentration standards and is found to be consistent with the AQMP for the first criterion.

B. Criterion 2 - Exceed Assumptions in the AQMP?
Consistency with the AQMP assumptions is determined by performing an analysis of the proposed project with the assumptions in the AQMP. The emphasis of this criterion is to ensure that the analyses conducted for the proposed project are based on the same forecasts as the AQMP. The 2016-2040 Regional Transportation/Sustainable Communities Strategy, prepared by SCAG, 2016, includes chapters on: the challenges in a changing region, creating a plan for our future, and the road to greater mobility and sustainable growth. These chapters currently respond directly to federal and state requirements placed on SCAG. Local governments are required to use these as the basis of their plans for purposes of consistency with applicable regional plans under CEQA. For this project, the City of Compton Land Use Plan defines the assumptions that are represented in the AQMP.

The proposed project is currently zoned as Limited Commercial (CL) and Parking (P) and has a land use classification of Medium Density Residential (8.1-17.0 dwelling units per acre) in the City of Compton General Plan. The project includes a General Plan Amendment to General Commercial (GC) and a Change of Zone to Limited Commercial and Planned Development Zones (C-L-D). The project is proposing to develop the approximately 2.45-acre project site with 60 single-family (attached) townhomes at 24.5 dwelling units per acre. Therefore, the proposed project is not currently consistent with the existing land use designation and zoning.

The General Commercial (1.00 FAR maximum) category allows for a wide range of retail and service commercial uses designed to meet communitywide and sub-regional shopping and service needs.

Typical permitted uses include retail businesses, personal service establishments, food and beverage sales, hotels and motels, automotive sales, and repair businesses, as well as low-intensity professional offices and financial institutions. Any use permitted in the Medium- Density and High-Density Residential categories is also allowed in General Commercial. The High-Density Residential General Plan land use designation permits 17.1 to 34 dwelling unit per net acre; therefore, the as the project is proposing 24 dwelling units per acre it would be consistent with the proposed General Commercial land use designation.

Therefore, once the General Plan Amendment and Change of Zone is approved, the project would be consistent with the City’s land use and zoning designations. Although the project may initially result in an inconsistency with the AQMP on paper, the inconsistency would not necessarily constitute a conflict with the AQMP. The SCAQMD acknowledges that strict consistency with all aspects of the AQMP is not required in order to make a finding of no conflict. Rather, a project is considered to be consistent with the AQMP if it furthers one or more policies and does not obstruct other policies. The project would implement contemporary energy-efficient technologies and regulatory/operational programs required per Title 24, CalGreen and City standards. Generally, compliance with SCAQMD emissions reductions and Compton Residential Development
Air Quality and Greenhouse Gas Impact Study
City of Compton, CA Air Quality Emissions Impact
43 control requirements also act to reduce project air pollutant emissions. Project compliance with regulatory/operational programs is consistent with and supports overarching AQMP air pollution reduction strategies. Project support of these strategies promotes timely attainment of AQMP air quality standards and would bring the project into conformance with the AQMP. Therefore, the proposed project is not anticipated to exceed the AQMP assumptions for the project site and is found to be consistent with the AQMP for the second criterion.

Based on the above, the proposed project will not result in an inconsistency with the SCAQMD AQMP.

Therefore, a less than significant impact will occur.

The greenhouse gas emissions from project construction equipment and worker vehicles are shown in Table 11. The emissions are from all phases of construction. The total construction emissions amortized over a period of 30 years are estimated at 24.54 metric tons of CO2e per year. Annual CalEEMod output calculations are provided in Appendix B.

7.2 Operational Greenhouse Gas Emissions Impact
Operational emissions occur over the life of the project. The unmitigated operational emissions for the project are 833.41 metric tons of CO2e per year as shown in Table 12. Therefore, the project’s GHG emissions do not exceed the SCAQMD draft threshold of 3,000 metric tons CO2e per year for all land uses. Therefore, the proposed project’s GHG emissions are considered to be less than significant. <Table 12 next page>

7.3 Greenhouse Gas Plan Consistency
The proposed project would have the potential to conflict with any applicable plan, policy or regulation of an agency adopted for the purpose of reducing the emissions of greenhouse gases. As stated previously, the City of Compton does not currently have a Climate Action Plan; therefore, the project has been compared to the goals of the CARB Scoping Plan and the GHG emissions reduction goal of SB-32.

Scoping Plan
Emission reductions in California alone would not be able to stabilize the concentration of greenhouse gases in the earth’s atmosphere. However, California’s actions set an example and drive progress towards a reduction in greenhouse gases elsewhere. If other states and countries were to follow California’s emission reduction targets, this could avoid medium or higher ranges of global temperature increases. Thus, severe consequences of climate change could also be avoided.

The ARB Board approved a Climate Change Scoping Plan in December 2008. The Scoping Plan outlines the State’s strategy to achieve the 2020 greenhouse gas emissions limit. The Scoping Plan “proposes a comprehensive set of actions designed to reduce overall greenhouse gas emissions in California, improve our environment, reduce our dependence on oil, diversify our energy sources, save energy, create new jobs, and enhance public health” (California Air Resources Board 2008). The measures in the Scoping Plan have been in place since 2012.

This Scoping Plan calls for an “ambitious but achievable” reduction in California’s greenhouse gas emissions, cutting approximately 30 percent from business-as-usual emission levels projected for 2020, or about 10 percent from today’s levels. On a per-capita basis, that means reducing annual emissions of Compton Residential Development
Air Quality and Greenhouse Gas Impact Study
City of Compton, CA Greenhouse Gas Impact Analysis
46 14 tons of carbon dioxide for every man, woman and child in California down to about 10 tons per person by 2020.

In May 2014, CARB released its First Update to the Climate Change Scoping Plan (CARB 2014). This Update identifies the next steps for California’s leadership on climate change. While California continues on its path to meet the near-term 2020 greenhouse gas limit, it must also set a clear path toward longterm, deep GHG emission reductions. This report highlights California’s success to date in reducing its GHG emissions and lays the foundation for establishing a broad framework for continued emission reductions beyond 2020, on the path to 80 percent below 1990 levels by 2050.

In November 2017, CARB release the 2017 Scoping Plan. This Scoping Plan incorporates, coordinates, and leverages many existing and ongoing efforts and identifies new policies and actions to accomplish the State’s climate goals, and includes a description of a suite of specific actions to meet the State’s 2030 GHG limit. In addition, Chapter 4 provides a broader description of the many actions and proposals being explored across the sectors, including the natural resources sector, to achieve the State’s mid and longterm climate goals.

Guided by legislative direction, the actions identified in the 2017 Scoping Plan reduce overall GHG emissions in California and deliver policy signals that will continue to drive investment and certainty in a low carbon economy. The 2017 Scoping Plan builds upon the successful framework established by the Initial Scoping Plan and First Update, while identifying new, technologically feasible, and cost-effective strategies to ensure that California meets its GHG reduction targets in a way that promotes and rewards innovation, continues to foster economic growth, and delivers improvements to the environment and public health, including in disadvantaged communities. The Plan includes policies to require direct GHG reductions at some of the State’s largest stationary sources and mobile sources. These policies include the use of lower GHG fuels, efficiency regulations, and the Cap-and Trade Program, which constrains and reduces emissions at covered sources.

As the latest, 2017 Scoping Plan builds upon previous versions, project consistency with applicable strategies of both the 2008 and 2017 Plan are assessed in Table 13. As shown in Table 13, the project is consistent with the applicable strategies and would result in a less than significant impact.

SB-32
SB-32 requires the state board to ensure that statewide greenhouse gas emissions are reduced to 40 percent below the 1990 level by 2030. SCAQMD's thresholds used Executive Order S-3-05 goal as the basis for deriving the screening level. The California Governor issued Executive Order S-3-05, GHG Emission, in June 2005, which established the following reduction targets:
• 2010: Reduce greenhouse gas emissions to 2000 levels
• 2020: Reduce greenhouse gas emissions to 1990 levels
• 2050: Reduce greenhouse gas emissions to 80 percent below 1990 levels.

Compton Residential Development
Air Quality and Greenhouse Gas Impact Study
City of Compton, CA Greenhouse Gas Impact Analysis
47 As the SCAQMD uses EO S-3-05 as the basis for their screening level, and EO S-3-05 includes the longterm goal to reduce greenhouse gas emissions to 80 percent below 1990 levels by 2050, the project would also be consistent with the goal of SB 32 (to reduce greenhouse gas emissions to 40 percent below 1990 levels by 2030). Therefore, projects that meet the current interim emissions targets/thresholds established by SCAQMD would also be on track to meet the reduction targets for 2030. Furthermore, all of the post 2020 reductions in GHG emissions are addressed via regulatory requirements at the State level and the project will be required to comply with these regulations as they come into effect.

Therefore, as the project's emissions do not exceed the SCAQMD draft GHG emissions threshold of 3,000 metric tons CO2e per year, the project would not conflict with any applicable plan, policy or regulation of an agency adopted for the purpose of reducing the emissions of greenhouse gases. Furthermore, the project will comply with applicable Green Building Standards and City of Compton’s policies regarding sustainability (as dictated by the City's General Plan). <Table 13 next page>

8. Existing General Plan Vision 2010: Medium Density Residential (8.1 to 17 du/acre net)
The Medium Density Residential (MDR), General Plan designation, allows for residential development up to 17 units per net acre and a population density of up to 66 persons per acre. Development typically consists of low-rise apartments, townhomes and condominiums, and single-family patio homes on small lots. Uses and development densities permitted in the Low-Density Residential category are also appropriate for Medium Density Residential areas (see Figure B – General Plan).

9. Existing Zoning: C-L – Limited Commercial & P – Automobile Parking The Limited Commercial Zone (C-L) is established to provide neighborhood, community, and regional retail business areas with related uses. The Automobile Parking Zone (P) is established to provide for off-street parking for residential, commercial, industrial, public, and other uses in the City (see Figure C – Zoning).

Currently, the existing zoning is not consistent with the General Plan.

11. Description of the Site and Project:

Environmental Setting
The Project site consists of approximately 2.45 acres of vacant land. A records review of aerial photography performed for the Phase I Environmental Site Assessment prepared by Stantec Consulting Services, Inc. determined the Project site was used for light agricultural purposes between 1928 and 1963. Then by 1977, the property was developed with a convalescent hospital and associated parking.

By 2005 the convalescent hospital had been demolished, and the property has been vacant ever since. It is noted that the City Planning Commission adopted Resolution 3828 on June 13, 2007, for a Conditional Use Permit (CUP) case number 2589, Variance case number 2590, and Tentative Tract Map 67558 to build a Planned Unit Development of 41 townhouse units. However, this project was not built.

Concord Residential Project Page 3 City of Compton
The site is bounded by West Compton Boulevard to the north, South Kemp Avenue to the east, South Dwight Avenue to the west, and West 151st Street to the south.

Curb, gutter, and sidewalk already exist on West Compton Boulevard, South Kemp Avenue, and South Dwight Avenue. As well, seven (7) mature trees exist in the right-of-way on West Compton Boulevard. The trees include five (5) Ficus (Moraceae) and two (2) Jacaranda mimosifolia trees.

Regionally, the subject site is in the Peninsular Ranges geomorphic province, characterizing southern California’s southwest portion. It is in these areas where major right-lateral active fault zones predominately trend northwest to southeast. The Peninsular Ranges province comprises plutonic and metamorphic rock, with lesser amounts of Tertiary volcanic and sedimentary rock, Quaternary drainage in-fills, and sedimentary veneers.

The Project site is underlain by undocumented artificial fills and young Quaternary alluvium. Elevations onsite range between approximately 81 feet to 85 feet above mean sea level, with a relative low point near the site’s northeast corner. Existing site drainage is generally directed as sheet flow in the northeast direction and overflows into West Compton Boulevard and South Kemp Avenue’s rights-of-way.

Within West Compton Boulevard and South Kemp Avenue, two (2) existing catch basins capture and convey stormwater to an existing Los Angeles County Flood Control District (LACFCD) 66” storm drain facility, which flows in the easterly direction and outlets to the existing Compton Creek. Compton Creek drains to the existing Los Angeles River and, ultimately, the Pacific Ocean at San Pedro Bay.

Project Description
The Project consists of the construction of 60 townhomes with private garages, private drive aisles, sidewalks, guest parking areas, and common landscaped areas. The Project site will be accessible via two (2) entrances/exits along West 151st Street. The project is being built under an air space condominium map TM82807.

The Project has been designed to provide housing for larger families with three (3) and four (4) bedroom floor plan designs. The design includes solar roofs, and the townhomes will be all-electric with no natural gas. Ten (10) of the units will be for moderate-income families, with the other fifty (50) units being market rate.

The Project includes the following discretionary approvals. • GPA 21-001 – General Plan Map Amendment (GPA) – The amendment changes the land use designation on the subject property from Medium Density Residential (MDR) to General Commercial (GC).
• COZ 21-003 – Change of Zone (CZ) – Change of Zone changes the existing C-L – Limited Commercial & P – Automobile Parking Zones to the C-L – Limited Commercial Zone.
• CUP 21-008 – Conditional Use Permit (CUP) – Conditional Use Permit to permit a condominium development in the C-L – Commercial Limited Zone. • TTM 21-001 – Tentative Tract Map 82807 – the map subdivides the 2.45- acres to create a single air space condominium map.

Concord Residential Project Page 4 City of Compton
In addition, the following approvals will also be needed to process the project. • Development Agreement – The agreement covers the details of the City’s sale of the land known as Assessor’s Parcel Number (APN) 6161-001-902 to City Ventures to develop sixty (60) single-family townhomes. • Density Bonus – Parking Ratio – Tandem Parking pursuant to Government Code Section 65915 (p) (5) a development providing affordable units may provide onsite parking through tandem parking.
• Undergrounding Exemption – The requested exemption regards the undergrounding of utilities on West Compton Boulevard pursuant to Chapter 26 – Undergrounding of Utilities Facilities of the Municipal Code. • Street Tree Removal – The request to remove the seven (7) mature street trees on West Compton Boulevard should pursuant to Section 30-43.7 – Removal of Landscaping or Trees of the Municipal Code.

GPA 21-001 – General Plan Map Amendment (GPA) – (Figure B – General Plan) The underlying General Plan designation of MDR – Medium-Density Residential is inconsistent with the existing zoning of C-L – Commercial Limited and P – Parking.

To create consistency with the General Plan and the Zoning designation of C-L – Commercial Limited while permitting a 60-unit townhome condominium Project the applicant is proposing to change the General Plan land use designation to General Commercial.

The General Commercial (1.00 FAR maximum) category allows for a wide range of retail and service commercial uses designed to meet communitywide and subregional shopping and service needs. Typical permitted uses include retail businesses, personal service establishments, food and beverage sales, hotels and motels, automotive sales, and repair businesses, as well as low-intensity professional offices and financial institutions. Any use permitted in the Medium-Density and High-Density Residential categories is also allowed in General Commercial.

Since the High-Density Residential General Plan land use designation permits

17.1 to 34 du/acre net, the General Commercial land use designation is an appropriate designation for this Project, which proposes 24.5 du/acre.

COZ 21-003 – Change of Zone (CZ) – (Figure C – Zoning)
The Project proposes to change the existing C-L – Limited Commercial & P – Automobile Parking Zones to the C-L – Limited Commercial Zone. The Limited Commercial Zone (C-L) is established to provide neighborhood, community, and regional retail business areas with related uses.

CUP 21-003 – Conditional Use Permit (CUP) – (Figure E – Conceptual Site Plan) In the C-L Zone, specific uses are permitted subject to a CUP obtained pursuant to the provisions of Section 30-26 – Conditional Use Permits (CUP) of the City’s Municipal Code. permitted with a CUP. Therefore, this Project is being processed under a CUP.

Concord Residential Project Page 5 City of Compton
The development proposes sixty (60) townhome units with private garages, private drive aisles, sidewalks, guest parking areas, and common and private landscaped areas. The Project site will utilize two driveways off West 151st Street.

The Project has eight (8) three-story buildings, including four (4) ten-plexes and four (4) five-plexes. There are two plan types: Plan 1 at 1,404-square-feet and Plan 2 at 1,664-square-feet. Plan 1 has a two-car tandem parked private garage on the 1st floor and livable space on the 2nd and 3rd floors. Plan 2 has a two-car side-by-side parked private garage plus livable space on the 1st floor and livable space on the 2nd and 3rd floors. Second and third-floor living spaces for both units will further benefit from private outdoor decks (see Figures F through I).

The building’s architectural style is “Transitional,” blending both Traditional and Contemporary styles. Exterior façade materials are composed of a stucco field with board & batten siding accents. The roof level is distinguished by a perimeter, asphalt shingled hip roof punctuated with projecting gables and parapets. Architectural accents include aesthetically placed wood trellises, wood guardrails, bracket-supported awning roofs, and contemporary coach lights (see Figures F through I).

TTM 21-001 – Tentative Tract Map 82807 – (Figure D – TTM-82807) The map proposes to subdivide the property into a single air space condominium lot for townhome purposes. On-site streets will be provided as easements.

Development Agreement
The City and City Ventures are entering into a Development Agreement that will provide the details of the City’s sale of the land to City Ventures to develop a sixty (60) unit, townhome air space condominium Project.

Density Bonus – Parking Ratio – Tandem Parking
Although the applicant is not requesting a density increase under Density Bonus Law (Government Code 65915) they are providing ten units affordable to moderate income families and are requesting to utilize the tandem parking provision of Density Bonus Law pursuant to Government Code Section 65915 (p) (5). As noted in 65915 (f) the definition of “Density Bonus” for the purpose of the law does not require the increase in density.

Concord Residential Project Page 6 City of Compton
Undergrounding Exemption
SCE has overhead transmission lines on four (4) 80-foot-tall poles along the West Compton Boulevard frontage of the Project site. These poles hold sixteen (16) different lines at six (6) different heights on the poles ranging from 12kV to 66kV and including lines for AT&T and Charter. The lines extend to the east and west of the Project site along West Compton Boulevard. All other utilities are underground.

The developer is requesting an exemption from the undergrounding of utilities requirement pursuant to Chapter 26 – Undergrounding of Utilities Facilities of the Municipal Code.

Street Tree Removal
Seven (7) mature trees exist in the right-of-way on West Compton Boulevard. The trees include five (5) Ficus (Moraceae) and two (2) Jacaranda mimosifolia trees.

The developer proposes to replace the trees with 36” box trees at a one-to-three (1:3) ratio. The developer is seeking approval to remove the damaged tree(s) in accordance with Section 30-43.7 – Removal of Landscaping or Trees of the Municipal Code.

Construction Characteristics
Construction activities within the Project area will consist of on-site grading, building, paving, and architectural coating. Per the Project-specific scoping agreement (TJW Engineering, Inc.), the Project is to be operational in 2022; therefore, construction is estimated to start no sooner than February 2022.

Proposed site drainage will be collected and conveyed by two (2) proposed curbinlet catch basins and an area drain system to two (2) proposed underground Concord Residential Project Page 7 City of Compton
detention systems, which will discharge to the existing LACFCD 66” storm drain at two (2) points of connection. Low flows will be directed to proposed Modular Wetlands System (MWS) Biofiltration Vaults for water quality treatment prior to entering the proposed detention systems. During larger storm events, stormwater runoff will bypass the treatment systems and be conveyed directly to the proposed detention system. The detention system will be equipped with an orifice to mitigate the peak discharge rate to the allowable peak flow rate (Allowable Q) provided Los Angeles County Department of Public Works (LACDPW). Excess flows will be temporarily detained as they are released at the Allowable Q. Refer to Appendix H of the Preliminary Hydrology and Hydraulics Study for the Allowable Q provided by LACFCD.

Although the property is relatively flat, the Project will export approximately 4,320 cubic yards of dirt in approximately 308 truckloads. Required street improvements will include the following:
• There will be new sidewalk installed on Compton Boulevard, South Kemp Avenue and Dwight Avenue.
• Curb and gutter will remain unless damaged and directed to be replaced for Compton Boulevard, Dwight Avenue and South Kemp Avenue. • West 151st Street will receive new curb, gutter and sidewalk. • There will be new curb returns and curb ramps installed at all four corners of the Project.

The Project includes preliminary grading, drainage, and water quality management plans.

12. Have California Native American tribes traditionally and culturally affiliated with the project area requested consultation pursuant to Public Resources Code section 21080.3.1? If so, is there a plan for consultation that includes, for example, the determination of significance of impacts to tribal cultural resources, procedures regarding confidentiality, etc.? Note: Conducting consultation early in the CEQA process allows tribal governments, lead agencies, and project proponents to discuss the level of environmental review, identify and address potential adverse impacts to tribal cultural resources, and reduce the potential for delay and conflict in the environmental review process. (See Public Resources Code section 21080.3.2.) Information may also be available from the California Native American Heritage Commission’s Sacred Lands File per Public Resources Code section 5097.96 and the California Historical Resources Information System administered by the California Office of Historic Preservation. Please also note that Public Resources Code section 21082.3(c) contains provisions specific to confidentiality.

Pursuant to California Public Resources Code §21080.3.1(Assembly Bill (AB) 52 of 2014), which requires local governments to conduct meaningful consultation with California Native American tribes that have requested to be notified by lead agencies of proposed projects in the geographic area with which the tribe is traditionally and culturally affiliated, the City is requesting to conduct AB 52 tribal consultation with your tribe. It is understood that the time allotted for a Native American Tribe to respond to a lead agency and request consultation in writing was recently extended by an additional 30-days in California Public Resources Code §21080.3.1, for a total of 60-days for any housing development project application, determined to be complete on or after March 4, 2020, and before December 31, 2021, under Assembly Bill 1561 approved by the Governor September 28, 2020.

Concord Residential Project Page 8 City of Compton
In addition, the Project includes a General Plan Land Use Map change and, therefore, must also comply with California Public Resources Code §65352.3 - 65352.4 (Senate Bill (SB) 18), which requires local governments to conduct meaningful consultation with California Native American tribes on the contact list maintained by the Native American Heritage Commission prior to the adoption or amendment of a city or county general plan to protect Native American cultural places on lands that may be affected by the proposal.

Consultation under AB 52 and SB 18 commenced on April 19, 2021, with six (6) tribes.
• Gabrieleno Band of Mission Indians - Kizh Nation
• Gabrieleno/Tongva San Gabriel Band of Mission Indians • Gabrielino/Tongva Nation
• Gabrielino Tongva Indians of California Tribal Council • Gabrielino Tongva Tribe
• Soboba Band of Luiseño Indians
The 60-day response period for AB 52 will end on June 18, 2021. The 90-day response period for SB 18 will end on July 19, 2021. The City will consult with all tribes requesting a consultation and will coordinate the appropriate mitigation if any.

On the basis of this initial evaluation:

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

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

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

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

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

EVALUATION OF ENVIRONMENTAL IMPACTS:
1) A brief explanation is required for all answers except “No Impact” answers that are adequately supported by the information sources a Lead Agency cites in the parentheses following each question. A “No Impact” answer is adequately supported if the referenced information sources show that the impact simply does not apply to projects like the one involved (e.g., the project falls outside a fault rupture zone).

A “No Impact” answer should be explained where it is based on project-specific factors as well as general standards (e.g., the project will not expose sensitive receptors to pollutants, based on a project-specific screening analysis). 2) All answers must take account of the whole action involved, including off-site as well as on-site, cumulative as well as project-level, indirect as well as direct, and construction as well as operational impacts.
3) Once the Lead Agency has determined that a particular physical impact may occur, then the checklist answers must indicate whether the impact is potentially significant, less than significant with mitigation, or less than significant. “Potentially Significant Impact” is appropriate if there is substantial evidence that an effect is significant. If there are one or more “Potentially Significant Impact” entries when the determination is made, an EIR is required.
4) Less Than Significant with Mitigation Incorporated” applies where the incorporation of mitigation measures has reduced an effect from “Potentially Significant Impact” to a “Less than Significant Impact.” The Lead Agency must describe the mitigation measures, and briefly explain how they reduce the effect to a less than significant level (mitigation measures from Section XVII, “Earlier Analyses,” may be crossreferenced). 5) Earlier analyses may be used where, pursuant to the tiering, program EIR, or another CEQA process, an effect has been adequately analyzed in an earlier EIR or negative declaration. Section 15063(c)(3)(D). In this case, a brief discussion should identify the following:
a) Earlier Analyses Used. Identify and state where they are available for review. b) Impacts Adequately Addressed. Identify which effects from the above checklist were within the scope of and adequately analyzed in an earlier document pursuant to applicable legal standards, and state whether such effects were addressed by mitigation measures based on the earlier analysis. c) Mitigation Measures. For effects that are “Less than Significant with Mitigation Measures Incorporated,” describe the mitigation measures which were incorporated or refined from the earlier document and the extent to which they address site-specific conditions for the project.
6) Lead agencies are encouraged to incorporate into the checklist references to information sources for potential impacts (e.g., general plans, zoning ordinances).

Reference to a previously prepared or outside document should, where appropriate, include a reference to the page or pages where the statement is substantiated.

Concord Residential Project Page 26 City of Compton
7) Supporting Information Sources. A source list should be attached, and other sources used, or individuals contacted should be cited in the discussion. 8) This is only a suggested form, and lead agencies are free to use different formats; however, lead agencies should normally address the questions from this checklist that are relevant to a project’s environmental effects in whatever format is selected. 9) The explanation of each issue should identify:
a) the significance criteria or threshold, if any, used to evaluate each question; and
b) the mitigation measure identified, if any, to reduce the impact to less than significance.

I. AESTHETICS – Except as provided in Public Resources Code Section 21099 – Modernization of Transportation Analysis for Transit-Oriented Infill Projects – Would the project:
a) Have a substantial adverse effect on a scenic
vista?
Response:

The Project site is relatively flat, vacant, and surrounded by urban development. The proposed threestory residential buildings will complement the surrounding area and will not affect a scenic vista.

The City has evaluated the Project against City standards. The Project has been found, as conditioned, to meet all standards. Therefore, the Project will have a less than significant impact, directly, indirectly, or cumulatively on scenic vistas.
b) Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway?
Response:

The site is bounded by West Compton Boulevard to the north, South Kemp Avenue to the east, South Dwight Avenue to the west, and West 151st Street to the south. Curb, gutter, and sidewalk already exist on West Compton Boulevard, South Kemp Avenue, and South Dwight Avenue. As well, seven (7) mature trees exist in the right-of-way on West Compton Boulevard. The trees include five (5) Ficus (Moraceae) and two (2) Jacaranda mimosifolia trees. These trees will be removed during Project construction and replaced with 36” box trees. There will be a one-to-one (1:3) ratio of replacement for each tree. The provisions of Section 30-43.7 – Removal of Landscaping or Trees of the Municipal Code will be followed.

Per a review of the CalTrans Scenic Highways Program, no state scenic highways exist in the City of Compton. However, several roadway corridors were highlighted for improvement by the City through design guidelines and regulations, public investment, and private incentives under the 1998 Corridor Improvement Plan. Compton Boulevard is one (1) of these corridors. The City Public Works Department is currently working on the Compton Boulevard Street Design Project, which covers Compton Boulevard between the east and the west City limits. The Public Works Department has reviewed the Project design for consistency with this program.

City staff will ensure that the Project is designed consistent with the City’s requirements and the surrounding area. Therefore, the Project will have a less than significant impact, directly, indirectly, or cumulatively, on scenic resources within a state or City designated scenic highway/corridor. c) In non-urbanized areas, substantially degrade
the existing visual character or quality of public
views of the site and its surroundings? (Public
views are those that are experienced from publicly accessible vantage point). If the project is in an urbanized area, would the project conflict
with applicable zoning and other regulations
governing scenic quality?
Response:

The Project is in an urbanized area and has been designed to meet all applicable zoning requirements and other City regulations governing scenic quality. Therefore, the Project will have a less than significant impact, directly, indirectly, or cumulatively, on the existing visual character. d) Create a new source of substantial light or glare
which would adversely affect day or nighttime
views in the area?
Response:

To reduce impacts related to light pollution, the City requires that all developments introducing new light sources, or modifications to existing light sources, to shield all such devices. An exterior lighting plan has been submitted to City for approval. A photometric study and manufacturer’s cut sheets of all exterior Concord Residential Project Page 28 City of Compton

lighting on the buildings, landscaped areas, and parking lots was submitted with the exterior lighting plan.

All on-site lighting provides a minimum intensity of one-foot-candle at ground level and maximum intensity of ten-foot-candles at ground level throughout the areas serving the public and used for parking, with a ratio of average light to minimum light of four-to-one (4:1). The light sources are shielded to minimize off-site glare, and do not direct light skyward, and are to be directed away from adjacent properties and public rights-of-ways. Lights proposed to be mounted on buildings will be down-lights.

The proposed buildings are designed using an earth tone palette, and the site will include landscaping.

Therefore, glare from the buildings should be minimal. Mitigation Measure, MM AES-1, will ensure that glare is not a potential issue.

As designed, conditioned, and mitigated, the impacts of lighting and glare will be less than significant with mitigation, directly, indirectly, and cumulatively.

MM AES-1: Prior to building permit issuance, the developer shall ensure that the design of the buildings shall reduce the number of reflective surfaces used in the construction to minimize new sources of glare. Exterior building materials shall use earth tone light colors with low reflectance. Any bare metallic surfaces found on infrastructures such as pipes and poles shall be painted to minimize reflectance and glare.

AGRICULTURE AND FOREST RESOURCES – In determining whether impacts to agricultural resources are significant environmental effects, lead agencies may refer to the California Agricultural Land Evaluation and Site Assessment Model (1997) prepared by the California Dept. of Conservation as an optional model to use in assessing impacts on agriculture and farmland. In determining whether impacts to forest resources, including timberland, are significant environmental effects, lead agencies may refer to information compiled by the California Department of Forestry and Fire Protection regarding the state’s inventory of forest land, including the Forest and Range Assessment Project and the Forest Legacy Assessment project; and forest carbon measurement methodology provided in Forest protocols adopted by the California Air Resources Board. – Would the project:
a) Convert Prime Farmland, Unique Farmland, or
Farmland of Statewide Importance (Farmland),
as shown on the maps prepared pursuant to the
Farmland Mapping and Monitoring Program of
the California Resources Agency, to non-agricultural use? Response:

The subject site is “not mapped” on the Farmland Mapping and Monitoring Program. The “not mapped” designation means an area that falls outside of the California Department of Conservation soil survey.

The adjacent properties on all four sides are developed with single-family residential and commercial uses making agricultural uses on the subject site problematic. Development, particularly residential development, can make farming more difficult or costly due to conflicts between non-agricultural and agricultural activities. For example, residents may complain about noise, dust, odors, and low-flying aircraft used to dust or spray crops. Increased restrictions on agriculture processes and other aspects of encroachment on agricultural areas can lower productivity, increase costs, and otherwise impair agricultural operations. The site has been vacant since at least 2005 and was used for a convalescent hospital prior to that time between 1977 and 2005. It is noted that the site was used for light agricultural purposes Concord Residential Project Page 29 City of Compton

between 1928 and 1963. Therefore, the Project will have no impact, directly, indirectly, or cumulatively on farmland.
b) Conflict with existing zoning for agricultural use,
or a Williamson Act contract?
Response:

The City is primarily an urban environment with no agricultural land under commercial cultivation. The Residential Agriculture (R-A) zoned areas in the City permit private and commercial field crops, orchards, horticultural nurseries, and similar agricultural uses. However, the subject site is zoned C-L and P and is proposed to be zoned R-M-SP-1. These zones do not permit agricultural uses. As well, the site is not subject to a Williamson Act Contract. Therefore, the Project will have no impact, directly, indirectly, or cumulatively, on zoning for agricultural use or on a Williamson Act contract. c) Conflict with existing zoning for, or cause rezoning of, forest land (as defined in Public Resources Code Section 12220(g)), timberland (as defined by Public Resources Code Section
4526), or timberland zoned Timberland Production (as defined by Government Code Section 51104(g))?
Response:

In Southern California, including the City of Compton, climate and topography limit the types and locations of forest lands and their potential for commercial or industrial timber utilization. Accordingly, there is no existing or currently proposed zoning of forest land, timberland, or Timberland Production Zones within the City. Therefore, the Project would not conflict with the existing zoning for, or cause rezoning of, forest land, timberland, or timberland zoned Timberland Production. The Project will have no impact, directly, indirectly, or cumulatively.
d) Result in the loss of forest land or conversion of
forest land to non-forest use?
Response:

There is no commercial forestry or timber production industry within the City. Therefore, the Project would not result in the loss of forest land or the conversion of forest land to a non-forest use. The Project will have no impact, directly, indirectly, or cumulatively. e) Involve other changes in the existing environment which, due to their location or nature, could result in the conversion of Farmland, to non-agricultural use or conversion of forest land to nonforest use? Response:

As previously indicated, the Project site has not been used for agricultural purposes since 1977 and due to the adjacent residential and commercial uses. Agricultural uses on this site would be problematic.

Therefore, the Project would not result in the conversion of farmland to non-agricultural use and will have no significant impact, directly, indirectly, or cumulatively.

An Air Quality and Greenhouse Gas Impact Study was prepared for the Project by MD Acoustics. The results follow below.

The SCAQMD CEQA Handbook states that “New or amended General Plan Elements (including landuse zoning and density amendments), Specific Plans, and significant projects must be analyzed for consistency with the AQMP.” Strict consistency with all aspects of the plan is usually not required. A proposed project should be consistent with the AQMP if it furthers one or more policies and does not obstruct other policies. The SCAQMD CEQA Handbook identifies two key indicators of consistency:
(1) Whether the project will result in an increase in the frequency or severity of existing air quality violations or cause or contribute to new violations or delay timely attainment of air quality standards or the interim emission reductions specified in the AQMP. (2) Whether the project will exceed the assumptions in the AQMP in 2016 or increments based on the year of project buildout and phase.

Both of these criteria are evaluated in the following sections.

A. Criterion 1 - Increase in the Frequency or Severity of Violations Based on the air quality modeling analysis in the Compton Residential Development Air Quality and Greenhouse Gas Impact Study, neither short-term construction impacts nor long-term operations will result in significant impacts based on the SCAQMD regional and local thresholds of significance.

Therefore, the proposed Project is not projected to contribute to the exceedance of any air pollutant concentration standards and is found to be consistent with the AQMP for the first criterion.

B. Criterion 2 - Exceed Assumptions in the AQMP?
Consistency with the AQMP assumptions is determined by performing an analysis of the proposed Project with the assumptions in the AQMP. The emphasis of this criterion is to ensure that the analyses conducted for the proposed Project are based on the same forecasts as the AQMP. The 2016-2040 Regional Transportation/Sustainable Communities Strategy, prepared by SCAG, 2016, includes chapters on: the challenges in a changing region, creating a plan for our future, and the road to greater mobility and sustainable growth. These chapters currently respond directly to federal and state requirements placed on SCAG. Local governments are required to use these as the basis of their plans for consistency with applicable regional plans under CEQA. For this Project, the City of Compton Land Use Plan defines the assumptions represented in the AQMP.

The proposed Project is currently zoned as Limited Commercial (C-L) and Parking (P). It has a land-use classification of Medium Density Residential (8.1-17.0 dwelling units per acre) in the City of Compton General Plan. The Project includes a General Plan Amendment to General Commercial (GC) and a Change of Zone to Limited Commercial Zone (C-L). The Project proposes developing the approximately

2.45-acre Project site with 60 single-family (attached) townhomes at 24.5 dwelling units per acre. Therefore, the proposed Project is not currently consistent with the existing land use designation and zoning.

The General Commercial (1.00 FAR maximum) category allows for a wide range of retail and service commercial uses designed to meet communitywide and sub-regional shopping and service needs. Typical permitted uses include retail businesses, personal service establishments, food and beverage sales, hotels and motels, automotive sales, and repair businesses, as well as low-intensity professional offices and financial institutions. Any use permitted in the Medium-Density and High-Density Residential categories is also allowed in General Commercial. The High-Density Residential General Plan land use designation permits 17.1 to 34 dwelling units per net acre; therefore, as the Project proposes 24.5 dwelling units per acre, it would be consistent with the proposed General Commercial land use designation.

Therefore, once the General Plan Amendment and Change of Zone are approved, the Project would be consistent with the City’s land use and zoning designations. Although the Project may initially result in an inconsistency with the AQMP on paper, the inconsistency would not necessarily constitute a conflict Concord Residential Project Page 31 City of Compton

with the AQMP. The SCAQMD acknowledges that strict consistency with all aspects of the AQMP is not required in order to make a finding of no conflict. Instead, a project is considered consistent with the AQMP if it furthers one or more policies and does not obstruct other policies. The Project would implement contemporary energy-efficient technologies and regulatory/operational programs required per Title 24, CalGreen, and City standards. Generally, compliance with SCAQMD emissions reductions and control requirements also act to reduce project air pollutant emissions. Project compliance with regulatory/operational programs is consistent with and supports overarching AQMP air pollution reduction strategies. Project support of these strategies promotes timely attainment of AQMP air quality standards and would bring the Project into conformance with the AQMP. Therefore, the proposed Project is not anticipated to exceed the AQMP assumptions for the Project site and is found to be consistent with the AQMP for the second criterion.

Based on the above, the proposed Project will not result in an inconsistency with the SCAQMD AQMP.

Therefore, a less than significant impact will occur on the SCAQMD AQMP directly, indirectly, or cumulatively. b) 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? Response:

Cumulative projects include local development as well as general growth within the Project area. However, as with most development, the greatest source of emissions is from mobile sources, which travel well out of the local area. Therefore, from an air quality standpoint, the cumulative analysis would extend beyond any local projects and, when wind patterns are considered, would cover an even larger area.

Accordingly, the cumulative analysis for the Project’s air quality must be generic by nature.

The Project area is out of attainment for both ozone and PM10 particulate matter. Construction and operation of cumulative projects will further degrade the local air quality and the air quality of the South Coast Air Basin. The greatest cumulative impact on the quality of regional air cell will be the incremental addition of pollutants mainly from increased traffic from residential, commercial, and industrial development and the use of heavy equipment and trucks associated with the construction of these projects. Air quality will be temporarily degraded during construction activities that occur separately or simultaneously.

However, in accordance with the SCAQMD methodology, projects that do not exceed the SCAQMD criteria or can be mitigated to less than criteria levels are not significant and do not add to the overall cumulative impact. The Project does not exceed any of the thresholds of significance and therefore is considered less than significant.
c) Expose sensitive receptors to substantial pollutant concentrations? Response:

Construction Air Quality Emissions Impact
The latest version of CalEEMod was used to estimate the onsite and offsite construction emissions. The emissions incorporate Rule 402 and 403. Rule 402 and 403 (fugitive dust) are not considered mitigation measures as the Project by default is required to incorporate these rules during construction.

Regional Significance Thresholds for Construction Emissions The following CEQA significance thresholds for construction emissions are established for the Basin:
• 75 pounds per day (lbs/day) of VOC • 150 lbs/day of PM10 • 100 lbs/day of NOx • 55 lbs/day of PM2.5
• 550 lbs/day of CO • 150 lbs/day of SO2
Projects in the basin with construction-related emissions exceeding any of the emission thresholds are considered significant under SCAQMD guidelines.

The table above provides the Project’s unmitigated operational emissions. The table shows that the Project does not exceed the SCAQMD daily emission threshold and regional operational emissions are less than significant.

The Project does not exceed any of the thresholds of significance and, therefore, is considered less than significant.

Regional Significance Thresholds for Operational Emissions The daily operational emissions significance thresholds for the basin are as follows:
• 55 pounds per day (lbs/day) of VOC • 150 lbs/day of PM10 • 55 lbs/day of NOx • 55 lbs/day of PM2.5
• 550 lbs/day of CO • 150 lbs/day of SO2
Local Microscale Concentration Standards
The significance of localized project impacts under CEQA depends on whether ambient CO levels in the vicinity of the project are above or below State and federal CO standards. If ambient levels are below the standards, a project is considered to significantly impact if project emissions result in an exceedance of one or more of these standards. If ambient levels already exceed a State or federal standard, project emissions are considered significant if they increase 1-hour CO concentrations by 1.0 ppm or more or 8-hour CO concentrations by 0.45 ppm or more. The following are applicable local emission concentration standards for CO:
• California State 1-hour CO standard of 20.0 ppm
• California State 8-hour CO standard of 9.0 ppm

5.1.4 Thresholds for Localized Significance
Project-related construction air emissions may have the potential to exceed the State and Federal air quality standards in the project vicinity, even though these pollutant emissions may not be significant enough to create a regional impact on the South Coast Air Basin. To assess local air quality impacts, the SCAQMD has developed Localized Significant Thresholds (LSTs) to assess the project-related air emissions in the project vicinity. The SCAQMD has also provided Final Localized Significant Threshold Methodology (LST Methodology), June 2003, which details the methodology to analyze local air emission impacts. The Localized Significant Threshold Methodology found that the primary emissions of concern are NO2, CO, PM10, and PM2.5.

The emission thresholds were calculated based on the South-Central Los Angeles County source receptor area (SRA 12) and a disturbance of two acres per day at a distance of 25 meters (82 feet) for construction.

Localized Construction Emissions
The data provided in the table below shows that none of the analyzed criteria pollutants would exceed the local emissions thresholds at the nearest sensitive receptors. Therefore, a less than significant local air quality impact would occur from constructing the proposed Project.

SCAQMD Threshold for 25 meters (82 feet) or less2 65 346 7 4 Exceeds Threshold? No No No No
Notes:
1 Source: Calculated from CalEEMod and SCAQMD’s Mass Rate Look-up Tables for two acres in South Central Los Angeles County Source Receptor Area (SRA 12). Project will disturb a maximum of two acres per day (see Table 7 in the Air Quality and Greenhouse Impact Study). 2 The nearest sensitive receptors are the multiple-family residential land uses located approximately 35 feet (~11 meters) southeast and 50 feet (~15 meters) east of the project site, and the single-family residential land uses located approximately 50 feet (~15 meters) south of the project site; however, according to LST methodology, any receptor located closer than 25 meters should be based on the 25-meter threshold.

Localized Operational Emissions
Project-related air emissions from on-site sources such as architectural coatings, landscaping equipment, on-site usage of natural gas appliances as well as the operation of vehicles on-site may have the potential to exceed the State and Federal air quality standards in the Project vicinity, even though these pollutant emissions may not be significant enough to create a regional impact to the Air Basin.

As stated previously, according to SCAQMD LST methodology, LSTs would apply to the operational phase of a project if the project includes stationary sources or attracts mobile sources (such as heavyduty trucks) that may spend long periods queuing and idling at the site; such as industrial warehouse/transfer facilities. The proposed Project is a residential project and does not include such uses.

Therefore, due to the lack of stationary source emissions, no long-term localized significance threshold analysis is warranted.

Construction-Related Toxic Air Contaminant Impact
The greatest potential for toxic air contaminant emissions would be related to diesel particulate emissions associated with heavy equipment operations during the proposed Project's construction. The Office of Environmental Health Hazard Assessment (OEHHA) has issued the Air Toxic Hot Spots Program Risk Assessment Guidelines and Guidance Manual for the Preparation of Health Risk Assessments, February 2015, to describe the algorithms, recommended exposure variates, cancer, and noncancer health values, and the air modeling protocols needed to perform a health risk assessment HRA) under the Air Toxics Hot Spots Information and Assessment Act of 1987. Hazard identification includes identifying all evaluated substances for cancer risk and/or non-cancer acute, 8-hour, and chronic health impacts. In addition, identifying any multi-pathway substances that present a cancer risk or chronic non-cancer hazard via non-inhalation routes of exposure.

Given the relatively limited number of heavy-duty construction equipment and construction schedule, the proposed Project would not result in a substantial long-term source of toxic air containment emissions and corresponding individual cancer risk. Furthermore, construction-based particulate matter (PM) emissions (including diesel exhaust emissions) do not exceed any local or regional thresholds. Therefore, no significant short-term toxic air contaminant impacts would occur during the construction of the proposed Project.

The Project will have a less than significant impact on the exposure of sensitive receptors to substantial pollutant concentrations. d) Result in other emissions (such as those leading
to odors adversely affecting a substantial number of people? Response:

Potential sources that may emit odors during construction activities include the application of materials such as asphalt pavement. The objectionable odors produced during the construction process are shortterm in nature. The odor emissions are expected to cease upon the drying or hardening of the odorproducing materials. Diesel exhaust and VOCs would be emitted during construction of the Project, which are objectionable to some; however, emissions would disperse rapidly from the Project site and therefore should not reach an objectionable level nearest sensitive receptors. Due to the short-term nature and limited amounts of odor-producing materials being utilized, no significant impact related to odors would occur during the proposed Project's construction.

The SCAQMD recommends that odor impacts be addressed in a qualitative manner. Such an analysis shall determine whether the Project would result in excessive nuisance odors, as defined under the California Code of Regulations and Section 41700 of the California Health and Safety Code, and thus would constitute a public nuisance related to air quality.

Potential sources that may emit odors during the proposed Project's ongoing operations would include odor emissions from trash storage areas. Due to the distance of the nearest receptors from the Project site and through compliance with SCAQMD’s Rule 402, no significant impact related to odors would occur during the proposed Project's ongoing operations.

Response:

The site is bounded by West Compton Boulevard to the north, South Kemp Avenue to the east, South Dwight Avenue to the west, and West 151st Street to the south. Curb, gutter, and sidewalk already exist on West Compton Boulevard, South Kemp Avenue, and South Dwight Avenue. As well, seven (7) mature trees exist in the right-of-way on West Compton Boulevard. The trees include five (5) Ficus (Moraceae) and two (2) Jacaranda mimosifolia trees. These trees will be replaced with 36” box trees at a oneto-one (1:3) ratio per the provisions of Section 30-43.7 – Removal of Landscaping or Trees of the Municipal Code.

Los Angeles County does have SEA’s throughout the County, but a review of the County of Los Angeles’ Geographical Information System files on September 13, 2019, found that the Project site was not located in a biologically sensitive area or a SEA.

A review of the National Register of Historic Places Geographic Information System, the California Office of Historic Preservation Website, and the City’s General Plan found that Compton is located on one of the oldest communities in Los Angeles County, dating back to 1784 when it was once a part of Rancho San Pedro. One of Compton’s first homes, the Heritage House, was built in 1869 and is a State Historic Landmark.

Aerial photographs of the site dating back to 1928 are provided in the Phase I Environmental Site Assessment 930 Compton Boulevard – prepared by Stantec Consulting Services, Inc. A records review of aerial photography performed for the Phase I Environmental Site Assessment determined the Project site was used for light agricultural purposes between 1928 and 1963. Then by 1977, the property was developed with a convalescent hospital and associated parking. By 2005 the convalescent hospital had been demolished, and the property has been vacant ever since. Therefore, there will be no impact on the significance of a historical resource.
b) Cause a substantial adverse change in the significance of an archaeological resource pursuant to §15064.5?
Response:

A review of the National Register of Historic Places Geographic Information System, the California Office of Historic Preservation Website, and the City’s General Plan found that Compton is located on one of the oldest communities in Los Angeles County, dating back to 1784 when it was once a part of Rancho San Pedro. Archaeological sites exist in the City, but none are located in the area of the subject site.

The site has been developed at one time with a convalescent hospital that has since been demolished.

The disturbance of the property during this previous construction and demolition did not produce any archaeological resources. Therefore, there will be no impact on the significance of an archaeological resource.
c) Disturb any human remains, including those interred outside of formally dedicated cemeteries? Response:

No cemeteries or human remains are known to occur on-site, and it is unlikely that human remains will be uncovered during Project development. Pursuant to CEQA Guidelines 15064.5 (e), in the event of the accidental discovery or recognition of any human remains in any location other than a dedicated cemetery, the following steps shall be taken:
(1) There shall be no further excavation or disturbance of the site or any nearby area reasonably suspected to overlie adjacent human remains until:

impact due to wasteful, inefficient, or unnecessary consumption of energy resources, during project construction or operation?
Response:

Construction of the sixty (60) townhomes would require the typical use of energy resources. Energy would be consumed during site clearing, excavation, grading, and construction. The construction process would be typical. No site conditions or Project features would require an inefficient or unnecessary consumption of energy.

• Solid Waste Management; and
• All other mandatory CalGreen requirements for residential development.

The operation of the proposed residential units would involve energy for heating, cooling, and equipment operation. These facilities would comply with all applicable California Energy Efficiency Standards and 2019 CALGreen Standards.

Neither the construction nor operation of the Project would result in wasteful, inefficient, or unnecessary consumption of energy or wasteful use of energy resources. Therefore, impacts related to wasteful energy use would be less than significant, directly, indirectly, or cumulatively. b) Conflict with or obstruct a state or local plan for
renewable energy or energy efficiency?
Response:

As noted above, the Project has been designed in compliance with California’s Energy Efficiency Standards and 2019 CALGreen Standards. The Project would not conflict with or obstruct a state or local plan for renewable energy or energy efficiency; therefore, impacts would be less than significant, directly, indirectly, or cumulatively.

Several large, active fault systems, including the Whittier-Elsinore, the Newport-Inglewood, and the San Andreas, occur in the region surrounding the site. These fault systems have been studied extensively and, in large part, control the geologic structure of southern California.

The subject site is located in southern California, which is a tectonically active area. The type and magnitude of seismic hazards affecting a site are dependent on the distance to the causative fault and the intensity and magnitude of the seismic event. The seismic hazard may be primary, such as surface rupture and/or ground shaking, or secondary, such as liquefaction and/or ground lurching.

The site is located on the Santa Ana sub-block, approximately 1.3 miles east of the Newport-Inglewood fault zone, 4.9 miles southwest of the Puente Hills fault zone, 9.1 miles north Of the Palos Verdes fault zone, 11.3 miles south of the Elysian Park fault zone, and 13.1 miles southwest of the Whittier-Elsinore fault zone.

Surface Rupture
Active faults are not known to exist within the Project area. A review of Special Publication 42 indicates the site is not within a California State designated Alquist-Priolo earthquake fault zone. Accordingly, the potential for fault surface rupture on the subject site is very low.

Based on this analysis, compliance with an approved Geotechnical report, the California Building Code, and the City of Compton Municipal Code will ensure that risks associated with primary surface ground rupture should be considered “low.” Therefore, the potential hazards associated with fault rupture are considered less than significant, directly, indirectly, and cumulatively. ii) Strong seismic ground shaking?
Response:

Ground shaking hazards caused by earthquakes along other active regional faults do exist. The 2016 California Building Code requires use­modified spectral accelerations and velocities for most structural designs.

The site has been identified as a “D” site class in accordance with section 1613.3.2 of the CBC 2016.

Utilizing this information, the computer program ATC Hazards by Location and ASCE 7-10 criterion, the spectral response accelerations that can be utilized for the Project are presented in Figure 1 of the Geotechnical Report. The structural engineer should verify these parameters. Additional parameters should be determined by the structural engineer based on the Occupancy Category of the proposed structures.

Based on this analysis, compliance with an approved Geotechnical report, California Building Code, and the City of Compton Municipal Code will ensure that risks associated with ground shaking are considered less than significant, directly, indirectly, and cumulatively. iii) Seismic-related ground failure, including liquefaction? Response:

Seismic agitation of relatively loose saturated sands, silty sands, and some silts can result in a buildup of pore pressure. If the pore pressure exceeds the overburden stresses, a temporary quick condition known as liquefaction can occur. Liquefaction effects can manifest in several ways, including 1) loss of bearing; 2) lateral spread; 3) dynamic settlement; and 4) flow failure. Lateral spreading has typically been the most damaging mode of failure.

The more recent sediment has been deposited, the more likely it will be susceptible to liquefaction. Other factors that must be considered are groundwater, confining stresses, relative density, and the intensity and duration of seismically induced ground shaking.

Groundwater was not encountered during the geotechnical subsurface investigation at a depth approximately 51.5 feet below the ground surface. The regional groundwater map indicates that the historic- Concord Residential Project Page 41 City of Compton

high groundwater level is 10 feet below the ground surface (CDMG, 1997). The site is located in a liquefaction zone per the seismic hazard maps (CDMG, 1997).

Alta performed a liquefication analysis utilizing data from the hollow stem auger borings and laboratory test results to analyze the liquefaction potential of the young Quaternary alluvium. A description of Alta’s analysis and calculations is presented in Appendix E of the Geotechnical Report. A groundwater level of 10 feet below the existing ground surface was assumed. Alta’s findings are discussed below under the headings of the specific types of liquefaction, which can be manifested during seismic shaking.

Loss of Bearing:

Liquefaction can potentially cause foundation bearing failure due to ground softening and near-failure in bearing. Based on the removal recommendations presented in the geotechnical Report, Alta anticipates that the potential for loss of bearing will be minimal.

Lateral Spreading:

The lateral displacement of surficial blocks of sediment can occur due to liquefaction in a subsurface layer. The most pervasive forms of lateral spreading typically involve sites located near a “free-face” (large slopes, channels, etc.); however, it has been noted that lateral spreading can occur on sites with gently sloping (1% or more) ground, such as the subject site.

Determination of the potential for lateral spread is based on the presence of continuous potentially liquefiable soil layers underneath the structures, the presence of lateral confinement, and various analyses such as empirical modeling. Bartlett, Hansen, and Youd (2002) states that surface manifestation of lateral spread is typically limited to sites with liquefiable soils within 10 meters (32 feet) of grade and that sites underlain by soils with (N1)60 values 15 and greater do not experience significant displacements from earthquakes with magnitudes less than 8.

There were no layers within 32 feet of the existing ground surface with (Nl)Go values less than 15 that are susceptible to liquefaction. As such, it is Alta’s opinion that the potential for lateral spread to occur onsite is considered minimal upon the completion of remedial grading.

Settlement:

Settlement due to seismic shaking can occur due to both liquefaction of saturated sediments or rearrangement of dry sand particles. Alta’s liquefaction analysis was performed utilizing SPT from the hollow-stem auger borings and laboratory test results to analyze the potential amount of settlement. A description of Alta’s analysis and calculations are presented in Appendix E of the Geotechnical Report.

The calculations indicated that the potential amount of dynamic settlement is less than 1-inch. Dynamic settlement design recommendations are presented in Section 7.1 of the Geotechnical Report.

Flow Failure:

Due to the relatively flat nature of the site and the relatively horizontal deposition of the underlying deposits, the potential for flow failure onsite is considered low.

Implementation of existing state and local laws and regulations concerning soil liquefaction and ground failure is required of all projects in the City. Therefore, impacts related to liquefaction and ground failure would be less than significant, directly, indirectly, and cumulatively. iv) Landslides?
Response:

The site is situated on relatively level ground and is not immediately adjacent to any slopes or hillsides that could be potentially susceptible to slope instability. No signs of slope instability in the form of landslides, rockfalls, earth flows, or slumps were observed at or near the subject site during Alta’s Concord Residential Project Page 42 City of Compton

investigation. As such, risks associated with slope instability should be considered "negligible." Therefore, there will be no impacts related to landsliding and slope failure, directly, indirectly, and cumulatively. b) Result in substantial soil erosion or the loss of
topsoil?
Response:

Erosion is a large-scale impact caused by human activity and disturbance of surface soil, wind, and water. Erosion cannot be eliminated, although existing regulations such as the CBC (which includes erosion control measures and best management practices) and NPDES permit requirements can reduce the potential impacts of erosion. No signs of erosion were observed during Alta’s field investigation.

Risks associated with flooding and erosion should be evaluated and mitigated by the project design Civil Engineer.

The Project does propose to export approximately 4,320 cubic yards of soil. No import of soil is expected.

Adherence to state and local regulations will reduce impacts related to erosion to less than significant, directly, indirectly, and cumulatively.
c) Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on- or off­site landslide, lateral spreading, subsidence,
liquefaction or collapse?
Response:

See Responses VII a iii and iv above, and d below for additional information.

Adherence to the recommendations of the geotechnical investigation will ensure that the Project will have a less than significant impact on on-site or off-site landslide, lateral spreading, subsidence, liquefaction, or collapse either directly, indirectly, or cumulatively. d) Be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code (1994), creating substantial direct or indirect risks to life
or property?
Response:

Expansive soils contain certain types of clay minerals that shrink or swell as the moisture content changes; the shrinking or swelling can shift, crack, or break structures built on such soils. Arid or semiarid areas with seasonal changes of soil moisture experience a much higher frequency of problems from expansive soils than areas with higher rainfall and more constant soil moisture.

The California Building Code (CBC) 2016, Volume 2, Chapter 18, Division 1 Section 1803.2 mandates that special foundation design consideration is employed if the soil expansion Index is 20 or greater in accordance with Table 18-1-B. The methodology and scope for a geotechnical investigation are described in UBC Section 1803 and require assessing various factors, such as slope stability, soil strength, adequacy of load-bearing soils, the presence of compressible or expansive soils, and the liquefaction potential. The required content of the geotechnical report includes recommendations for foundation type and design criteria. These recommendations can include foundation design provisions intended to mitigate the effects of expansive soils, liquefaction, and differential settlement. In general, mitigation can be accomplished by combining ground modification techniques (i.e., stone columns, reinforcing nails and anchors, deep soil mixing, etc.), selecting an appropriate foundation type and configuration, and using appropriate building/foundation structural systems. Section 1804.5 Excavation, Grading, and Fill require the preparation of a geotechnical report where a building will be constructed on compacted fill.

The International Building Code (IBC) replaced earlier regional building codes (including the Uniform Building Code) in 2000 and established consistent construction guidelines for the nation. In 2006, the IBC was incorporated into the 2007 California Building Code (CBC) and currently applies to all structures being constructed in California. The national model codes are therefore incorporated by reference into Concord Residential Project Page 43 City of Compton

the building codes of local municipalities. The CBC includes building design and construction criteria that take into consideration the State’s seismic conditions.

Through adherence to state and local seismic and structural regulations (i.e., California Seismic Hazards Mapping Act, California Building Code, Compton Municipal Code, and the NPDES Permit Requirements), the impacts of expansive soils will be less than significant, directly, indirectly, or cumulatively. e) Have soils incapable of adequately supporting
the use of septic tanks or alternative wastewater
disposal systems where sewers are not available for the disposal of wastewater? Response:

The Project will be served by the Los Angeles County Sanitation District (LACSD) sewer infrastructure.

C&V Consulting, Inc. has prepared a Sewer Area Study. The existing sewer system analyzed in the area study has a design capacity above the calculated cumulative flow. The peak discharge at the downstream end of the sewer system 15” pipe entering the County Sanitation District No. 1 existing 31.3” sewer trunk main is calculated to be a rate of 1.8465 cfs with a flow depth of 7.61 inches. Refer to Appendix B of the Sewer Area Study for calculations and tabulated results. Therefore, it is concluded that the existing sewer system has adequate capacity for the proposed development.

Therefore, the Project will have no impact, directly, indirectly, or cumulatively in regard to septic systems, and the existing sewer system has adequate capacity for the proposed development. f) Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature? Response:

The Project site and the surrounding area, because of its artificial fill and alluvial geology, are not considered to be likely candidates for the discovery of paleontological resources. The likelihood of discovering such materials is also considered low due to the previous disturbance that has occurred on the site and the presence of fill materials. Therefore, the Project will not disturb any paleontological resources, and no impacts are anticipated.

Response:

The proposed Project would have the potential to conflict with any applicable plan, policy or regulation of an agency adopted for the purpose of reducing the emissions of greenhouse gases. The City of Compton does not currently have a Climate Action Plan; therefore, the Project has been compared to the goals of the CARB Scoping Plan and the GHG emissions reduction goal of SB-32.

Scoping Plan
The Scoping Plan calls for an “ambitious but achievable” reduction in California’s greenhouse gas emissions, cutting approximately 30 percent from business-as-usual emission levels projected for 2020, or about 10 percent from today’s levels. On a per-capita basis, that means reducing annual emissions of 14 tons of carbon dioxide for every man, woman, and child in California down to about 10 tons per person by 2020.

In May 2014, CARB released its First Update to the Climate Change Scoping Plan (CARB 2014). This Update identifies the next steps for California’s leadership on climate change. While California continues on its path to meet the near-term 2020 greenhouse gas limit, it must also set a clear path toward longterm, deep GHG emission reductions. This report highlights California’s success to date in reducing its GHG emissions and lays the foundation for establishing a broad framework for continued emission reductions beyond 2020, on the path to 80 percent below 1990 levels by 2050.

In November 2017, CARB released the 2017 Scoping Plan. This Scoping Plan incorporates, coordinates, and leverages many existing and ongoing efforts and identifies new policies and actions to accomplish the State’s climate goals and includes a description of a suite of specific actions to meet the State’s 2030 GHG limit. In addition, Chapter 4 provides a broader description of the many actions and proposals being explored across the sectors, including the natural resources sector, to achieve the State’s mid and long-term climate goals.

Guided by legislative direction, the actions identified in the 2017 Scoping Plan reduce overall GHG emissions in California and deliver policy signals that will continue to drive investment and certainty in a low carbon economy. The 2017 Scoping Plan builds upon the successful framework established by the Initial Scoping Plan and First Update while identifying new, technologically feasible, and cost-effective strategies to ensure that California meets its GHG reduction targets in a way that promotes and rewards innovation, continues to foster economic growth, and delivers improvements to the environment and public health, including in disadvantaged communities. The Plan includes policies to require direct GHG reductions at some of the State’s largest stationary sources and mobile sources. These policies include the use of lower GHG fuels, efficiency regulations, and the Cap-and-Trade Program, which constrains and reduces emissions at covered sources.

As the latest 2017 Scoping Plan builds upon previous versions, project consistency with applicable strategies of both the 2008 and 2017 Plan are assessed in the table below. As shown in the table below, the Project is consistent with the applicable strategies and would result in a less than significant impact.

SB-32
SB-32 requires the state board to ensure that statewide greenhouse gas emissions are reduced to 40 percent below the 1990 level by 2030. SCAQMD's thresholds used Executive Order S-3-05 goal as the Concord Residential Project Page 47 City of Compton

the basis for deriving the screening level. The California Governor issued Executive Order S-3-05, GHG Emission, in June 2005, which established the following reduction targets:
• 2010: Reduce greenhouse gas emissions to 2000 levels
• 2020: Reduce greenhouse gas emissions to 1990 levels
• 2050: Reduce greenhouse gas emissions to 80 percent below 1990 levels.

As the SCAQMD uses EO S-3-05 as the basis for their screening level, and EO S-3-05 includes the longterm goal to reduce greenhouse gas emissions to 80 percent below 1990 levels by 2050, the Project would also be consistent with the goal of SB 32 (to reduce greenhouse gas emissions to 40 percent below 1990 levels by 2030). Therefore, projects that meet the current interim emissions targets/thresholds established by SCAQMD would also be on track to meet the reduction targets for 2030. Furthermore, all of the post-2020 reductions in GHG emissions are addressed via regulatory requirements at the State level. The Project will be required to comply with these regulations as they come into effect.

Therefore, as the Project's emissions do not exceed the SCAQMD draft GHG emissions threshold of 3,000 metric tons CO2e per year, the Project would not conflict with any applicable plan, policy or regulation of an agency adopted for the purpose of reducing the emissions of greenhouse gases. Furthermore, the Project will comply with applicable Green Building Standards and City of Compton’s policies regarding sustainability (as dictated by the City's General Plan) and, therefore, will have a less than significant impact as noted above.

IX. HAZARDS AND HAZARDOUS MATERIALS – Would the project:
a) Create a significant hazard to the public or the
environment through the routine transport, use,
or disposal of hazardous materials?
Response:

Hazardous materials are highly regulated in California, including how they are transported, used, and stored. The development of a residential project will not result in the transport, use, or storage of massive quantities of hazardous materials. The City relies on the Fire Department's assistance and the County’s Department of Environmental Health in the regulation of hazardous materials.

The residents of the Project will store and use various chemicals for routine housekeeping and landscaping purposes. Comparable products will be required for the common recreation areas and general Project maintenance. However, none of these chemicals will be used in sufficient quantities to pose a threat to humans or the environment. Therefore, there will be no project-related impacts associated with the hazardous materials, directly, indirectly, or cumulatively. b) Create a significant hazard to the public or the
environment through reasonably foreseeable
upset and accident conditions involving the release of hazardous materials into the environment? Response:

The Project will not create hazards to the public through upset or accident as through the construction process; any hazardous materials will be handled, stored, and used in compliance with all Federal, State, and City regulations. As noted above, the Project will create single-family residences that will store and use various chemicals for routine housekeeping and landscaping purposes. Comparable products will be required for the common recreation areas and general Project maintenance. However, none of these chemicals will be used in sufficient quantities to pose a threat to humans or the environment. Therefore Concord Residential Project Page 48 City of Compton

there will be no project-related impacts associated with the hazardous materials, directly, indirectly, or cumulatively.
c) Emit hazardous emissions or handle hazardous

Response:

The Laurel Street Elementary School (1321 West Laurel Street) is located approximately 641-feet from the closest point of the subject property or a little over a .12 of a mile. Any hazardous materials will be handled, stored, and used in compliance with all Federal, State, and City regulations through the construction process. As noted above, the Project will create single-family residences that will store and use various chemicals for routine housekeeping and landscaping purposes. Comparable products will be required for the common recreation areas and general Project maintenance. However, none of these chemicals will be used in sufficient quantities to pose a threat to humans or the environment. The Project will not emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste to cause danger to surrounding schools. Therefore, no impacts, directly, indirectly or cumulatively to schools will occur.
d) Be located on a site which is included on a list
of hazardous materials sites compiled pursuant
to Government Code section 65962.5 and, as a
result, would it create a significant hazard to the
public or the environment?
Response:

Per the Phase I Environmental Site Assessment prepared by Stantec, the subject property is not located on a site included in a list compiled pursuant to Government Code Section 65962.3. The EnviroStor database did indicate that there are sites in the vicinity that may represent Recognized Environmental Conditions (RECs), Historical Recognized Environmental Conditions (HRECs), or de minimis conditions; however, the distance of these other sites from the subject site with respect to and the groundwater flow direction, the native soils, and regulatory status, none of the other sites are expected to affect the soil or groundwater quality at the subject site.

Nevertheless, due to the historic use of the property for light agriculture, a Phase II Environmental Site Assessment was performed by Stantec, with six (6) borings occurring on April 24, 2019. Analysis of the borings concluded that the historical agricultural use of the property did not represent a REC or human health risk considering the contemplated residential use of the subject site.

It is noted that the City has numerous high-pressure natural gas and petroleum pipelines. One such line, a natural gas line, is located within West Compton Boulevard. The Office of Pipeline Safety of the U.S.

Department of Transportation is the primary agency responsible for inspecting and maintaining pipelines running through the City. To ensure safety during construction, all requirements of Section 20-3 – Street Excavations shall be required, as applicable.

Therefore, this Project will have no impact, directly, indirectly, or cumulatively, in creating a significant hazard to the public or the environment.
e) For a project located within an airport land use
plan or, where such a plan has not been
adopted, within two miles of a public airport or
public use airport, would the project result in a
safety hazard or excessive noise for people residing or working in the project area? Response:

The Project is not located within a Los Angeles County Airport Land Use Commission (ALUC) area. The closest Airport is the Compton/Woodley Airport, but the subject site is outside the airport influence area for this airport.

Given the above guidelines, the Project will have no impact on creating a safety hazard for people residing or working in the Project area from airport operations, directly, indirectly, and cumulatively. f) Impair implementation of or physically interfere
with an adopted emergency response plan or
emergency evacuation plan?
Response:

Los Angeles County adopted the All-Hazards Mitigation Plan (AHMP), providing a framework for emergency response. The City also maintains an Emergency Operations Plan (EOP) that documents City policies for responding to major emergencies that threaten life, safety, and property. The plan establishes a chain of command and outlines the responsibilities of various City departments in the event of an emergency. The General Plan establishes Compton Boulevard as an evacuation route.

Two (2) driveways will provide project access off West 151st Street. The Project site is bounded by West Compton Boulevard to the north, West 151st Street to the south, South Kemp Avenue to the east, and South Dwight Avenue to the west. These existing streets are within the City’s established street system.

The Project will not alter the existing circulation pattern in the Project area. Emergency access and evacuation routes will be unaffected by the Project. In addition, the Project will comply with Section 20- 6 – Temporary Street Closures of the Municipal Code should any of the four streets/sidewalks/bicycle lanes need to be temporarily closed during construction.

The Project provides adequate access for emergency vehicles, including adequate street widths and vertical clearance on new streets. Implementation of federal, state, and local laws and regulations in this Project's construction ensures no impact on an adopted emergency response plan or evacuation plan.
g) Expose people or structures, either directly or
indirectly, to a significant risk of loss, injury or
death involving wildland fires?
Response:

The Project site is not within a fire hazard zone, as defined by the Los Angeles County AHMP, Figure 7- 1 – Los Angeles County Very High Fire Hazard Severity Zones. The City maintains its own Fire Department. The Project will not expose people or structures to significant risks associated with wildfires and, therefore, no impact, directly, indirectly, or cumulatively will occur.

See responses in Section XVX below for further information on water and wastewater.

The existing site is currently vacant, pervious land. Elevations onsite range between approximately 81 feet to 85 feet above mean sea level, with a relative low point near the site's northeast corner. Existing site drainage is generally directed as sheet flow in the northeast direction and overflows into the rightsof-way of West Compton Boulevard and South Kemp Avenue. Within West Compton Boulevard and South Kemp Avenue, two (2) existing catch basins capture and convey stormwater to an existing Los Angeles County Flood Control District (LACFCD) 66” storm drain facility within West Compton Boulevard, which flows in the easterly direction and outlets to the existing Compton Creek. Compton Creek drains to the existing Los Angeles River and ultimately the Pacific Ocean at San Pedro Bay.

Proposed site drainage will be collected and conveyed by two (2) proposed curb-inlet catch basins and an area drain system to two (2) proposed underground detention systems, which will discharge to the existing LACFCD 66” storm drain at two (2) points of connection. Low flows will be directed to proposed Modular Wetlands System (MWS) Biofiltration Vaults for water quality treatment prior to entering the proposed detention systems. During larger storm events, stormwater runoff will bypass the treatment systems and be conveyed directly to the proposed detention system. The detention system will be equipped with an orifice to mitigate the peak discharge rate to the allowable peak flow rate (Allowable Q) provided by the Los Angeles County Department of Public Works (LACDPW). Excess flows will be temporarily detained as they are released at the Allowable Q. Refer to Appendix H of the Preliminary Hydrology and Hydraulics Study for the Allowable Q provided by LACFCD.

The Project will comply with the requirements of Chapter 31 – Runoff Pollution Control of the Municipal Code. As such, a Preliminary Low Impact Development (LID) Plan has been prepared consistent with the Los Angeles County Department of Public Works LID Manual and the intent of the NPDES stormwater requirements (State Water Resources Control Board (SWRCB) National Pollutant Discharge Elimination System (NPDES) General Permit for Storm Water Discharges Associated with Construction and Land Disturbance Activities, Order No. 2009-0009-DWQ, NPDES No. CAS000002, dated July 1, 2010).

The Project will be served by the Los Angeles County Sanitation District (LACSD) sewer infrastructure.

C&V Consulting, Inc. has prepared a Sewer Area Study. The existing sewer system analyzed in the area study has a design capacity above the calculated cumulative flow. The peak discharge at the downstream end of the sewer system 15” pipe entering the County Sanitation District No. 1 existing 31.3” sewer trunk main is calculated to be a rate of 1.8465 cfs with a flow depth of 7.61 inches. Refer to Appendix B of the Sewer Area Study for calculations and tabulated results. Therefore, it is concluded that the existing sewer system has adequate capacity for the proposed development.

The Project's design and compliance with existing federal, state, and local water quality laws and regulations related to water quality standards will ensure a less than significant impact, directly, indirectly, and cumulatively to water quality and discharge.
b) Substantially decrease groundwater supplies or
interfere substantially with groundwater recharge such that the project may impede sustainable groundwater management of the basin? Response:

The City is located in the Central Basin groundwater basin. The Central Subbasin occupies a large portion of the southeastern part of the Coastal Plain of Los Angeles Groundwater Basin. This subbasin is commonly referred to as the “Central Basin.” It is bounded on the north by a surface divide called the La Brea high and, on the northeast, and east by emergent, less permeable Tertiary rocks of the Elysian, Repetto, Merced, and Puente Hills. The southeast boundary between Central Basin and Orange County Groundwater Basin roughly follows Coyote Creek, a regional drainage province boundary. The southwest boundary is formed by the Newport Inglewood fault system and the associated folded rocks of the Newport Inglewood uplift. The Los Angeles and San Gabriel Rivers drain inland basins and pass across the surface of the Central Basin on their way to the Pacific Ocean. The average precipitation throughout the subbasin ranges from 11 to 13-inches, with an average of around 12-inches.

The City uses a blend of predominate groundwater from the Central Basin groundwater basin and surface water imported by the Metropolitan Water District of Southern California (MWD). MWD's imported water sources are a blend of State Water Project water from Northern California and water from the Colorado River Aqueduct. The City has court adjudicated water rights to pump approximately 70 percent of the City's water demand. The City utilizes eight (8) groundwater wells to pump potable water from a natural underground reservoir. The City also has three (3) imported water connections that help supplement the City's water demands.

The Project will be required to comply with City’s water-efficiency requirements, including the use of drought-tolerant planting materials and limited landscaping irrigation, as well as all water restrictions imposed by the Los Angeles County Department of Public Works (LACDPW) at the time the Project is constructed. Implementation of these and other applicable requirements, including those noted in Response X a) above, will assure that water-related impacts to groundwater recharge are reduced to less than significant, directly, indirectly, and cumulatively. c) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river or through the addition of impervious surfaces, in a manner which would:
i) Result in substantial erosion or siltation on- or
off-site?
Response:

There are no natural drainages on the Project site; the Project will not alter any existing drainage patterns. Proposed drainage will be directed as sheet flow overland and through a series of area drains toward proposed Modular Wetlands System (MWS) Biofiltration Vaults for water quality treatment prior to discharging to the existing LACFCD 66” storm drain within West Compton Boulevard. The proposed area drain system will collect surface runoff within landscaped and backyard areas and convey flows directly to the proposed MWS Biofiltration Vaults via the proposed underground storm drain. Street surface flows will be conveyed via the proposed curb and gutter toward two (2) proposed curb-inlet catch basins located along the private drive aisle. The proposed catch basins will be equipped with a Dvert system designed to divert low flows to the proposed MWS Biofiltration Vaults. Treated stormwater will be conveyed via proposed underground storm drain to proposed underground detention systems, which will be outflow controlled to mitigate peak discharge to the existing LACFCD storm drain within West Compton Boulevard. During larger storm events and when the MWS Biofiltration Vaults are at capacity, the Dvert system within the catch basins and an internal bypass within the MWS Biofiltration Vaults will allow for high flows to bypass treatment and flow directly to the proposed detention systems via the proposed storm drain system. Drainage from the site will be conveyed from the detention system to the existing LACFCD 66” storm drain at two (2) points of connection. Upon discharging to the existing LACFCD storm drain, site runoff will follow the historic drainage pattern.

Implementing Best Management Practices (BMPs) required by the City and implemented through the Project’s Low Impact Development (LID) Plan will mitigate potential erosion impacts to a less than significant level directly, indirectly, and cumulatively. ii) Substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or offsite?
Response:

In addition to Response X a) & b) above, the design and implementation of the basins will be reviewed and approved by the City Engineer as well as the Los Angeles County Department of Public Works (LACDPW) to assure compliance with all applicable local, state, and Federal standards.

Implementation of these and other applicable requirements will assure that drainage and stormwater will not create or contribute water, which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff. Therefore, the Project will have a less than significant impact, directly, indirectly, or cumulatively to the rate or amount of surface runoff in a manner that would result in flooding on- or off-site.

iii) Create or contribute runoff water which would
exceed the capacity of existing or planned
stormwater drainage systems or provide substantial additional sources of polluted runoff? Response:

See Response X a) & b) above.
iv) Impede or redirect flood flows?
Response:

No signs of flooding were observed when Alta did their field investigation for the Geotechnical Report.

As described throughout this section, the Project will be required to comply with all applicable water quality standards. To further minimize potential water quality degradation, the Project will be connected to the sewer system and on-site/off-site stormwater conveyance system. No impacts to Project-related water quality degradation will occur, directly, indirectly, and cumulatively. d) In flood hazard, tsunami, or seiche zones, risk
release of pollutants due to project inundation?
Response:

A seiche and tsunami are defined below. Since the Project site is not located near a body of water or the ocean, the Project is not subject to these hazards.

A seiche is a temporary disturbance or oscillation in the water level of a lake or partially enclosed body of water, especially one caused by changes in atmospheric pressure.

Tsunami is a long high sea wave caused by an earthquake, submarine landslide, or other disturbance.

The Project site is not located within a 100-year mapped flood zone (FEMA Flood Insurance Rate Map No. 06037C1815F (September 26, 2008). The Project would redirect on-site drainage patterns; however, it would not impede or redirect flood flows. As referenced, all drainage would be managed to ensure pre-construction flows off-site are maintained. The Project would not expose people or structures to flood hazards from severe storm events.

Compliance with existing federal, state, and local flood hazard laws and regulations pertaining to the design of the Project will ensure the Project will not be impacted by a flood hazard directly, indirectly, or cumulatively.
e) Conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan? Response:

As noted throughout this Section, the Project will comply with all City, County, state, and federal requirements for water quality and sustainable groundwater. Compliance with existing federal, state, and local flood hazard laws and regulations pertaining to the design of the Project will ensure that the Project will have result in no impact from a flood hazard impact, directly, indirectly, and cumulatively.

XI. LAND USE AND PLANNING – Would the project:
a) Physically divide an established community?
Response:

The Project site is vacant land with established single-family residential neighborhoods to the east and south and commercial development to the west and north. An additional sixty (60) townhomes will not divide an existing community but rather will expand an existing community. Therefore, no impact either directly, indirectly, or cumulatively will occur to an established community. b) Cause a significant environmental impact due to
a conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect?
Response:

The underlying General Plan designation of MDR – Medium-Density Residential is inconsistent with the existing zoning of C-L – Commercial Limited and P – Parking. To create consistency with the General Plan and the Zoning designation of C-L – Commercial Limited while permitting a 60-unit townhome condominium Project the applicant is proposing to change the General Plan land use designation to General Commercial.

The General Commercial category allows any use permitted in the Medium-Density and High-Density Residential categories. Since the High-Density Residential General Plan land use designation permits

17.1 to 34 du/acre net, the General Commercial land use designation is an appropriate designation for this Project, which proposes 24.5 du/acre.

In addition, the applicant is also proposing to change the existing C-L – Limited Commercial & P – Automobile Parking Zones to the C-L – Limited Commercial Zone. The Limited Commercial Zone (C-L) is established to provide neighborhood, community, and regional retail business areas with related uses.

The proposed General Plan land use designation and zone change will bring consistency between the two land-use maps while implementing the General Plan policies, including the following:

Land Use Element
Policy 2.1 (M): Provide increased market-rate housing opportunities.

Housing Element
Goal 1: The City of Compton will improve the housing supply and the choice of housing opportunities through private investment and, where necessary, through public action and financing.

Policy 2.3: The City of Compton will encourage variety in the supply of housing at costs affordable to the various income levels of the population.

XII. MINERAL RESOURCES – Would the project:
a) Result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the state? Response:

Mineral deposits are limited to clay deposits used for bricks within the City. However, the City is near a number of active oil fields. The Rosecrans oilfield is located approximately two miles to the west. The East Los Angeles oilfield is located approximately seven (7) miles to the northeast, and the Dominguez oilfield is located approximately five (5) miles to the south. There are also several oil and natural gas wells located in the City. Most of these wells are in the southern portion of the City.

Based on Alta's review of geologic literature and their subsurface investigation, the Project site is underlain by undocumented artificial fills and young Quaternary alluvium. The geologic units are briefly described below.

Artificial Fill (Map symbol af)
Artificial fill was found in the upper two (2) to five (5) feet. It consists of light to dark brown, silty clay in a dry to moist, stiff condition, with some areas containing concrete cobbles up to 11 inches in diameter.

Young Quaternary Alluvium (Map symbol Qya)
Young Quaternary alluvium underlies the artificial fill, which consists of light brown to brown, tan with some orange mottling, silty clay, clayey silt, sandy silt, sand, and silt in a moist, stiff to very stiff, and medium dense to dense condition. The unit was logged to a maximum depth of 51.5 feet below the ground surface.

The artificial fill is most likely a result of the previous convalescent hospital development. As such, the clay within the fill would not be beneficial for the making of brick.

The Surface Mining and Reclamation Act (SMARA) Mineral Land Classification system designates the City as being in the San Gabriel Production-Consumption Region. However, the Project site occurs in an urban setting and is not suitable for mineral resource land uses. The Project will have a less than significant impact, directly, indirectly, and cumulatively on mineral resources. b) Result in the loss of availability of a locallyimportant mineral resource recovery site delineated on a local general plan, specific plan, or other land use plan?
Response:

The Project site is not delineated on a local general plan, specific plan, or other land use plan and will, therefore, have no impact, directly, indirectly, and cumulatively on the availability of important mineral resources.

The Noise Impact Study analyzed future noise impacts to the Project and compared the results to the City’s Noise Standards. The analysis detailed the estimated exterior noise levels associated with traffic from adjacent roadway sources.

Off-site Traffic Noise Impact
The potential off-site noise impacts caused by the increase in vehicular traffic due to the Project were calculated at a distance of 50 feet. The distance to the 55, 60, 65, and 70 dBA CNEL noise contours are also provided for reference. The noise level at 50 feet is representative of approximate distances to existing homes along the subject roadway. The noise contours were calculated for the following scenarios and conditions:
• LOS D Condition: This scenario refers to the existing year traffic noise condition and is demonstrated in the table below.
• LOS D + Project Condition: This scenario refers to the existing year plus project traffic noise condition and is demonstrated in the table below.

LOS D/LOS D + Project Scenario Comparison
The table below provides the LOS D and LOS D + Project noise conditions and shows the change in noise level due to the proposed Project. As shown in the table, the increase in traffic noise for the Existing and Existing + Project scenario would have a nominal increase of 0.1 dBA at 50 feet from the centerline of the subject roadway.

Traffic noise from the local roadway network was evaluated and compared to the City’s Exterior Noise standard. Per the City’s Exterior Noise Standard (Table N-2 from the City’s General Plan, Noise Element), the residential noise limit is 65 dBA CNEL. As shown in the table above, Existing Plus Project traffic 65 dBA CNEL noise projections from Compton Boulevard will reach up to 79 feet from the centerline of the road. Residential structures are located approximately 50-feet away from the centerline of Compton Boulevard and have a projected noise level of 68 dBA. It should be noted that the existing noise level exceeds the 65 dBA noise limit, so 68 dBA becomes the standard.

2. A minimum of 12 dBA noise reduction is assumed with a "windows open" condition.

3. A minimum of 20 dBA noise reduction is assumed with a "windows closed" condition.

4. Indicates the required STC rating to meet the interior noise standard.

As shown in the table above, the interior noise level will range from 56 dBA CNEL with the windows open and 48 dBA CNEL with the windows closed.

To meet the City’s interior 45 dBA CNEL standard, a “windows closed” condition is required. The windows and sliding glass doors directly facing Compton Boulevard will require a minimum STC rating of 26 for the 1st and 2nd floors (MM NOI-1). A “windows closed” condition simply means that to achieve a 45 dBA CNEL interior noise level, the windows must be closed, and does not mean the windows must be fixed.

Therefore, the Project will have a less than significant impact with mitigation on interior noise.

MM NOI-1: The windows and sliding glass doors facing the West Compton Boulevard shall require a minimum STC rating of 26 for the 1st and 2nd floors.

Construction Noise Impact
The degree of construction noise may vary for different areas of the Project site and vary depending on the construction activities. Noise levels associated with the construction will vary with the different phases of construction.

Construction Noise
The Environmental Protection Agency (EPA) has compiled data regarding the noise-generated characteristics of typical construction activities. The data is presented in the table below.

Vibrators 68 - 82
Notes:
1 Referenced Noise Levels from the Environmental Protection Agency (EPA) Construction is anticipated to occur during the permissible hours according to the City’s General Plan.

Construction noise is considered a short-term impact and would be considered significant if construction activities are taken outside the allowable times described in the City’s General Plan (Section 7-12.22).

Construction noise will have a temporary or periodic increase in the ambient noise level above the existing noise level within the Project vicinity. Furthermore, noise reduction measures are provided to reduce construction noise further. The construction noise impact is considered less than significant; however, construction noise level projections are provided.

Typical operating cycles for these types of construction equipment may involve one or two minutes of full power operation followed by three to four minutes at lower power settings. Noise levels will be loudest during the grading phase. A likely worst-case construction noise scenario during grading assumes the use of a grader, a dozer, an excavator, and three (3) backhoes operating at 80 feet from the nearest sensitive receptor.

To ensure that construction activities do not disrupt the adjacent land uses, mitigation measures for noise reduction MM NOI-2 through MM NOI-6 shall be required.

The Project will have a less than significant impact with mitigation on the generation of temporary or permanent increases in ambient noise levels in the vicinity of the Project.

MM NOI-2: Construction shall occur during the hours of 7:00 AM to 7:00 PM.

MM NOI-3: Stationary construction noise sources such as generators or pumps should be located as far as feasibly possible from any existing adjacent residential units, as feasible.

MM NOI-4: Construction staging areas should be located as far as feasibly possible from any adjacent sensitive land uses as feasible.

MM NOI-5: During construction, the contactor shall ensure all construction equipment is equipped with appropriate noise attenuating devices.

MM NOI-6: Equipment shall be maintained so that vehicles and their loads are secured from rattling and banging.

MM NOI-7: Grading and construction contractors shall use quieter equipment as opposed to noisier equipment (such as rubber-tired equipment rather than track equipment), to the maximum extent feasible. b) Generation of excessive groundborne vibration
or groundborne noise levels?

Construction activities can produce a vibration that may be felt by adjacent land uses. The Project's construction would not require the use of equipment such as pile drivers, which are known to generate substantial construction vibration levels. The primary vibration source during construction may be from a bulldozer. A large bulldozer has a vibration impact of 0.089 inches per second peak particle velocity (PPV) at 25 feet, which is perceptible but below any risk to architectural damage.

The fundamental equation used to calculate vibration propagation through average soil conditions and distance is as follows:

PPVequipment = PPVref (100/Drec)n
Where: PPVref = reference PPV at 100ft.

Drec = distance from equipment to receiver in ft.
n = 1.1 (the value related to the attenuation rate through ground) The Caltrans Transportation and Construction Induced Vibration Guidance Manual thresholds in the table below provide general thresholds and guidelines as to the vibration damage potential from vibratory impacts.

Guideline Vibration Damage Potential Threshold Criteria Structure and Condition
Maximum PPV (in/sec)
Transient
Sources
Continuous/Frequent
Intermittent Sources
Extremely fragile historic buildings, ruins, ancient monuments 0.12 0.08 Fragile buildings 0.2 0.1
Historic and some old buildings 0.5 0.25
Older residential structures 0.5 0.3
New residential structures 1.0 0.5
Modern industrial/commercial buildings 2.0 0.5
Source: Table 19, Transportation and Construction Vibration Guidance Manual, Caltrans, Sept. 2013.

Note: Transient sources create a single isolated vibration event, such as blasting or drop balls. Continuous/frequent intermittent sources include impact pile drivers, pogo-stick compactors, crack-and-seat equipment, vibratory pile drivers, and vibratory compaction equipment.

At a distance of 80 feet, a large bulldozer would yield a worst-case 0.025 PPV (in/sec), which slightly perceptible, but sustainably below any risk of damage (0.5 in/sec PPV is the threshold of residential structures). The impact is less than significant, and no mitigation is required. c) For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two
miles of a public airport or public use airport,
would the project expose people residing or
working in the project area to excessive noise
levels?
Response:

The Project site is located outside the noise contours for the Compton/Woodley Airport and will have no impact on exposing people to excessive airport noise levels.

XIV. POPULATION AND HOUSING – Would the project:
a) Induce substantial unplanned population growth
in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of road or other
infrastructure)?
Response:

The City’s General Plan establishes the development potential of the City to accommodate the City’s growth. The Project, as proposed, will help to accommodate that growth but will not induce it.

The Project site is located on existing streets, and utilities and public facilities are all available in the immediate area. No new road or utility infrastructure is required. Project-related impacts are expected to be less than significant.
b) Displace substantial numbers of existing people
or housing, necessitating the construction of replacement housing elsewhere? Response:

The Project site is vacant and will not displace any persons or require the construction of replacement housing. Therefore, there is no impact on housing.

XV. PUBLIC SERVICES – Would the project:
a) 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:
i) Fire protection?
Response:

The Project is located approximately .9 miles from Fire Station #1, located at 201 South Acacia Avenue, three (3) minutes away. As a result, fire personnel will reach the site within the average 4.5-minute response time. The Fire Department will approve the Project site plan to ensure it meets applicable fire standards and regulations.

The Fire Department will review the Project for compliance with all Fire Codes. By implementing all regulations and City policies for development projects, the Project will have a less than significant impact on fire services, directly, indirectly, and cumulatively. ii) Police protection?
Response:

Police protection is provided by the Los Angeles County Sheriff’s Department. The Project site is served by the Compton Station, located at 301 South Willowbrook Avenue. Emergency response times throughout the City average 2.5-minutes.

The Project provides two (2) access points for the Police Department off of West 151st Street. The Police Department will review the Project for compliance with all Safety Codes. By implementing all regulations and City policies for development projects, the Project will have a less than significant impact on police services, directly, indirectly, and cumulatively.
iii) Schools?
Response:

The Project is located within the service area boundary of the Compton Unified School District. The closest school to the Project site is the Laurel Street Elementary School (1321 West Laurel Street), located approximately 641-feet from the closest point of the subject property or a little over a .12 of a mile. The Project is required to pay the state-mandated school fees in place at the time that development occurs. These fees are designed to mitigate impacts to schools by providing funds for the construction of new facilities. By implementing all regulations and City and School District policies for development projects, the Project will have a less than significant impact on schools, directly, indirectly, and cumulatively. iv) Parks?
Response:

The City of Compton Parks and Recreation Department maintains 14 local parks that encompass 60 acres of parkland. The nearest parks to the subject property are Gonzales, Walter R. Tucker, and Wilson Parks.

The Project will increase the demand for public parks. The City imposes a fee for residential projects of $4779.06 per unit. This fee is designed to reduce the impacts of new development on City park facilities.

By implementing all regulations and City policies for development projects, the Project will have a less than significant impact on parks, directly, indirectly, and cumulatively. v) Other public facilities?
Response:

The Project will result in a minor increase in demand for City services and facilities, including recreational trails and library services. This increase is consistent with the General Plan Vision 2010 projections for these facilities. It will be offset by the increased property and sales tax generated by the build-out of the Project. Therefore, impacts to other public facilities are less than significant, directly, indirectly, and cumulatively.

The Project will increase the demand for public parks. However, it will not increase the demand over that planned under the General Plan Vision 2010. The City imposes a fee for residential projects of $4779.06 per unit. This fee is designed to reduce the impacts of new development on City park facilities.

By implementing all regulations and City policies for development projects, the Project will have a less than significant impact on parks, directly, indirectly, and cumulatively. b) Does the project include recreational facilities or
require the construction or expansion of recreational facilities which have an adverse physical effect on the environment?
Response:

The Project does provide some open space areas. It will not require the construction or expansion of recreational facilities as the site was planned for residential development under the General Plan Vision 2010. Therefore, the Project will have no impact on recreational facilities, causing an adverse effect on the environment.

transit, roadway, bicycle and pedestrian facilities?
Response:

CITY OF COMPTON GENERAL PLAN 2010 – CIRCULATION ELEMENT

MASTER PLAN OF STREETS AND HIGHWAYS
Compton Boulevard is proposed in the General Plan as a Secondary Highway. A Secondary Highway has an 80-foot right-of-way with a 60-feet curb-to-curb. Currently, Compton Boulevard is already built and designed to the General Plan standards.

West 151st Street, South Kemp Avenue, and South Dwight Avenue are local streets, and the Project will build the half-width of each of these streets wherever it is currently missing.

ALTERNATIVE MODES OF TRANSPORTATION
Pedestrian and Bicycles
Sidewalks and curb ramps at intersections are present in the study area, except on the east side of South Dwight Avenue along the Project’s frontage and on the north side of West 151st Street along the Project’s frontage, where they are absent. The Project will complete sidewalks adjacent to the Project site for use by pedestrians.

The Bicycle Master Plan (May 2015) proposes a Class IV Protected Bicycle Lane on West Compton Boulevard. However, the Plan does not indicate which side of West Compton Boulevard the lane is proposed for, and the City Engineer has not requested that the Project accommodate such a lane.

Therefore, the Project will have a less than significant impact on on-site roadway and site access improvements.

The City of Compton is served by Los Angeles Metro, which provides bus service throughout Los Angeles County. The figure below shows the Metro routes in the vicinity of the City of Compton. Additionally, the Compton Renaissance Transit System provides limited local service within the City of Compton.

There is one bus route within one‐quarter mile of the Project site. Metro Route 51/351 travels between the Wilshire/Vermont Purple Lane Station to the Compton Transit Center. In the Project's vicinity, Route 51/351 runs along West Compton Boulevard with a stop at the West Compton Boulevard/South Dwight Avenue intersection adjacent to the Project site. Route 51/351 runs from 5:00 AM to 10:00 PM on weekdays with headways of 20‐35 minutes and weekends with 30‐45 minute headways.

TEMPORARY TRAFFIC IMPACTS FROM CONSTRUCTION
The Project will be export approximately 4,320-cubic yards of dirt during the grading stage of construction, which is approximately 308 truckloads. The Project will follow the requirements of Section 20-3.12 – Care of Excavated Material for trenching within the streets and Section 14-1.13 – Appendix Chapter 33 Excavation and Grading of the Municipal Code.

To ensure that construction trips will not significantly impact the area mitigation measure, MM TRAF-1 is proposed. Implementing MM TRAF-1 will ensure that construction trips will be less than significant with mitigation and will not significantly impact the roadway system.

MM TRAF-1: Prior to any lane closure or detour, the developer shall submit a Construction Traffic Management Plan per the California M.U.T.C.D. for review and approval by the City Engineer. The plan shall include, but not be limited to, signing, truck routes per the City of Compton Approved Truck Route Map (Figure C-4 of the General Plan Visions 2010), and construction hours of 7:00 a.m. to 7:00 p.m. Monday through Saturday per the Municipal Code Section 7-12. 22 – Construction or Repairing of Buildings, Pile Drivers, Hoists, Steam Shovels of the City of Compton Municipal Code.

CITY CAPITAL IMPROVEMENT PROGRAM (CIP)
There are no CIP projects proposed for West Compton Boulevard, South Kemp Avenue, West 151st Street, and South Dwight Street. Adherence to all Engineering requirements for the adjacent streets will ensure no impact on the City’s CIP, directly, indirectly, and cumulatively.

HIGHWAY SAFETY IMPROVEMENT PROJECT GRANTS FOR COMPTON BOULEVARD The City has received funding from two Highway Safety Improvement Project grants (HSIP Cycle 7 and 8) to improve Compton Boulevard. The Cycle 7 grant includes the installation of raised medians and Class II bicycle lanes on Compton Boulevard from Willowbrook Avenue to eastern City limits. The Cycle 8 grant includes the installation of bike lanes and lighting, as well as enhanced pedestrian crossings at 15 intersections on Compton Boulevard from Willowbrook Avenue to Central Avenue. Additional street improvements for the entire length of Compton Boulevard to complete both grants will utilize other various funding sources.

The City is currently in the design phase for Compton Boulevard and has not identified the type of street trees that would be included. Therefore, the streetscape for this project will be reviewed by the City for consistency with the development of the grant plans.

LOS ANGELES COUNTY METROPOLITAN TRANSPORTATION AUTHORITY CMP The Los Angeles County Metropolitan Transportation Authority Congestion Management Program (CMP) designates certain roadways as CMP facilities. West Compton Boulevard, South Kemp Avenue, West 151st Street, and South Dwight Avenue are not covered by the CMP.

Consistent with state statute, all local jurisdictions within Los Angeles County, including the County of Los Angeles, adopted and are currently implementing the Land Use Analysis Program. Generally, jurisdictions adopt resolutions or ordinances based on the model Land Use Analysis Program resolution in Appendix D of the CMP. Future modifications to the jurisdiction's adopted Land Use Analysis Program must be submitted to MTA prior to local adoption. These documents will be kept on file as evidence of local CMP implementation.

Techniques that jurisdictions have found useful in implementing and coordinating Land Use Analysis Program requirements include:
• Incorporating CMP Land Use Analysis Program requirements and related information into project/permit applications and guidance packages provided to project applicants. • Incorporating a CMP reference into Initial Study checklists. • Adding CMP-related requirements and information into standard Requests for Proposals and contracts for EIR consultants.
• Adding MTA and other area transit operators to standard mailing lists used for CEQA related notices.

Since this Project does not include any CMP-designated roadways or there would be no impact under the CMP’s guidelines, directly, indirectly, or cumulatively.

SUMMARY
Therefore, the Project as designed and conditioned will have a less than significant impact with mitigation, directly, indirectly, and cumulatively on any program plans, ordinances, or policies addressing the circulation system, including transit, roadway, bicycle and pedestrian facilities. b) Conflict or be inconsistent with CEQA Guidelines section 15064.3, subdivision (b)? Response:

Coordination with City staff has identified the use of OPR's Technical Advisory on Evaluating Transportation Impacts in CEQA (2018). OPR's Technical Advisory document outlines the screening criteria, a Concord Residential Project Page 65 City of Compton

threshold of significance, and requirements for VMT assessment of land use projects. Outlined in the Technical Advisory, the VMT threshold of significance has been identified as fifteen (15) percent below existing residential VMT per capita. In addition, the document outlines a variety of acceptable mitigation measures. This memorandum utilizes the California Air Pollution Control Officers Association (CAPCOA) Qualifying Greenhouse Gas Mitigation Measures (2010) for purposes of mitigation and VMT reduction.

The Project is surrounded by residential uses and will complement the adjacent area. Outlined in the CAPCOA document, travel demand measures are provided, reducing a project's VMT. Of particular note, LUT-01 references an increase in density and its impact on VMT; projects with increased densities reduce greenhouse gas emissions associated with traffic in several ways. Considering the proposed Project's density and applying the LUT-01, the Project's VMT can be reduced by 15.56%. As the Project's density can reduce the proposed Project's VMT by 15.56% (greater than 15%), it is assumed the project will have a less than significant transportation impact. c) Substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)?
Response:

Wherever necessary, roadways adjacent to the proposed project site and site access points should be constructed in compliance with recommended roadway classifications and respective cross-sections in the City of Compton General Plan Circulation Element or as directed by the City Engineer. The City Engineer has reviewed the Project, and the only possible hazard was one of stopping sight distance for the Project Driveways. As such, a Sight Distance Analysis was prepared.

Sight Distance Analysis
A sight distance analysis for the Project driveway has been prepared based on the “stopping sight distance” requirements determined by Topic 201 and Table 201.1 of the Caltrans Highway Design Manual (HDM), latest edition. The table below shows the minimum stopping sight distances based on the design speed, as displayed in Table 201.1 of the HDM.

Stopping Sight Distance
Design Speed (mph) Stopping Sight Distance
(ft)
25 150
30 200
35 250
40 300
45 360
50 430
Source: Table 201.1, Highway Design Manual (July 2, 2018) Note: mph = miles per hour; ft = feet
In this analysis, the movements being analyzed at the Project Driveway intersections are movements from the exiting vehicles onto West 151st Street. Since there is no posted speed limit on West 151st Street between South Dwight Avenue and South Kemp Avenue, the 85th percentile speed is assumed to be 25 miles per hour.

Exhibit 9 displays the sight distance conditions at the project driveway in relation to the existing sidewalk, striping, and parking on 151st Street. The exhibit shows the required 15-foot setback from the edge of travel way and the 15-feet of sight distance required based on the assumed 85th percentile speed of 25 miles per hour.

As shown in Exhibit 9, the stopping sight distance requirements would be impaired by existing parking 151st Street west and east of the driveways. To meet the stopping sight distance standard, approximately 348 feet of red-curb would need to be painted on the north side of 151st Street.

However, the traffic engineer, TJW, notes that Section 405.1 of the Highway Design Manual recommends that parking restrictions on urban driveways be set per California Manual on Uniform Traffic Control Devices (CA MUTCD) Section 3B.19. Section 3B.19 recommends a clearance of six-feet measured from the curb return should be provided at both sides of a driveway. It is TJW’s recommendation that the CA MUTCD guidance be followed and a clearance of 6-feet be provided at both sides of the driveway.

Therefore, with the implementation of mitigation measure, MM TRAF-2, the Project will have a less than significant impact on sight distance for the driveway on West 151st Street.

MM TRAF-2: Approximately six-feet of red‐curb shall be painted on both sides of the driveways and Section 3B.19 of Section 405.1 of the Highway Design Manual standards shall be applied. d) Result in inadequate emergency access?
Response:

The Project provides adequate access on-site for emergency vehicles (i.e., police and ambulance services) and can be accessed from all four sides by the Fire apparatus. The Project has been reviewed by the City Engineer and the City Fire Department and, as designed, will have no impact on emergency access.

A review of the National Register of Historic Places Geographic Information System, the California Office of Historic Preservation Website, and the City’s General Plan found that Compton is located on one of the oldest communities in Los Angeles County, dating back to 1784 when it was once a part of Rancho San Pedro. Archaeological sites exist in the City, but none are located in the area of the subject site.

The site has been developed at one time with a convalescent hospital that has since been demolished.

The disturbance of the property during this previous construction and demolition did not produce any archaeological resources.

Pursuant to AB 52 and SB 18 consultation with California Native American tribes requesting consultation within the City commenced on April 19, 2021. The six (6) tribes notified of this Project include the following tribes. • Gabrieleno Band of Mission Indians - Kizh Nation
• Gabrieleno/Tongva San Gabriel Band of Mission Indians • Gabrielino/Tongva Nation
• Gabrielino Tongva Indians of California Tribal Council • Gabrielino Tongva Tribe
• Soboba Band of Luiseño Indians
The 60-day response period for AB 52 will end on June 18, 2021. The 90-day response period for SB 18 will end on July 19, 2021. The City will consult with all tribes requesting a consultation and will coordinate the appropriate mitigation, if any into this environmental review.

Therefore, there will be no impact on 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).
ii) A resource determined by the lead agency, in
its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision (c) of Public Resources
Code Section 5024.1. In applying the criteria set
forth in subdivision (c) of Public Resources
Code Section 5024.1, the lead agency shall
consider the significance of the resource to a
California Native American tribe.

Response:

As noted above, archaeological sites exist in the City; however, none are located in the subject site as the site has been developed at one time with a convalescent hospital that has since been demolished.

The disturbance of the property during this previous construction and demolition did not produce any archaeological resources. As well, the City has started both AB 52 and SB 18 and AB 52 Tribal Consultations as noted above.

The disturbance of the property during this previous construction and demolition did not produce any archaeological resources. Therefore, it is anticipated the Project will have no impact on resources significant to a California Native American Tribe.

a) Require or result in the relocation or construction of new or expanded water, wastewater treatment or storm water drainage, electric
power, natural gas, or telecommunications facilities, the construction or relocation of which could cause significant environmental effects?
Response:

Water
See also responses Section X above and XIX b) below for additional information.

Water Supply Assessment
Senate Bill (SB) 610 (Chapter 643, Statutes of 2001; Water Code Sections 10910–10915) made changes to the Urban Water Management Planning Act to require additional information in UWMPs if groundwater is identified as a source available to the supplier. The information required includes a copy of any groundwater management plan adopted by the supplier, a copy of the adjudication order or decree for adjudicated basins, and if non-adjudicated, whether the basin has been identified as being over-drafted or projected to be over-drafted in the most current DWR publication on that basin. If the basin is in overdraft, that plan must include current efforts to eliminate any long-term overdraft. A key provision in SB 610 requires that large development projects supplied with water from a public water system and subject to CEQA be provided a specified water supply assessment, except as specified in the law. Large development projects include 500 or more residential units, 500,000 square feet of retail, commercial space, or 250,000 square feet of office commercial space. These assessments, prepared by “public water systems” responsible for service, address whether there are adequate existing or projected water supplies available to serve proposed projects, in addition to urban and agricultural demands and other anticipated development in the service area in which the project is located.

SB 221 (Chapter 642, Statutes of 2001; Government Code Section 66473.7) prohibits approval of subdivisions consisting of more than 500 dwelling units unless there is verification of sufficient water supplies for the project from the applicable water supplier(s). This requirement also applies to approvals that would increase the number of service connections by 10% or more for public water systems with less than 500 service connections. The law defines criteria for determining “sufficient water supply,” such as using normal, single-dry, and multiple-dry year hydrology and identifying the amount of water that the supplier can rely on to meet existing and future planned uses. Rights to extract additional groundwater, if used for the project, must be substantiated.

The Project proposes 60 townhomes served by the City of Compton Municipal Water District (CMWD).

Since the Project proposes less than 500 dwelling units, a water supply assessment (WSA) was not required.

The City of Compton Municipal Water District (CMWD) has two major sources of water. It currently has access to 5,780 acre-feet of groundwater that is supplied via seven (7) wells. Water is pumped from these wells and flows into a grid system, distributed using a gravity-fed system via 163 miles of 2 to 24- inch diameter pipes. In addition, the Metropolitan Water District of Southern California (MWD) supplies approximately 30-60% of the City’s water demand. MWD has three active interconnections to the City.

The purchased water from MWD augments the water from the wells via the distribution system and flows into four 3-million-gallon welded steel-plate storage tanks for a total of 12,000 million gallons of storage.

These tanks take up any fluctuations in system pressure or flow deficiencies.

CMWD will provide water to the site via one (1) six (6)-inch point of connection in West 151st Street at the westernmost driveway and one connection in Compton Boulevard. Per the CMWD’s 2010 Urban Water Management Plan (UWMP), CMWD has the supply needed to meet the demand of its customers through 2030 based on the land use designations of the General Plan Vision 2010. The conclusion is Concord Residential Project Page 69 City of Compton

based on the Metropolitan Water District (MWD) assurances that it would be able to supply member agency demands and the reliability of local groundwater supplies achieved through groundwater management plans. CMWD has committed to providing service to the planned uses of the General Plan, and this Project is consistent with the City’s General Plan. The Project will not require or result in the relocation or construction of new or expanded water lines or facilities, which could cause significant environmental effects. Therefore, the Project will have a less than significant effect, directly, indirectly, or cumulatively, on water facility expansion.

Wastewater Treatment
See also response Section X above and XIX c) below for additional information.

Sanitary sewage from the Project site will be connected to the existing 12-inch sanitary sewer line located in West Compton Boulevard through the new lines proposed within the newly created streets within the Project. The wastewater will then be transported to the Los Angeles County Sanitation District (LACSD) sewage system.

Wastewater in the City of Compton is collected by the LACSD sewage system and sent to one of eleven treatment or wastewater plants. At these plants, the wastewater goes through a three-stage treatment process consisting of primary, secondary, and tertiary treatment stages. After tertiary treatment, water is available for use to recycled water customers, use for groundwater recharge, or discharged into the ocean. Although the City of Compton is not part of a recycled water system, wastewater collected from the City is treated to recycled water standards and can be distributed through the LACSD’s recycled water supply system.

LACSD implements all requirements of the Regional Water Quality Control Board pertaining to water quality and wastewater discharge. LACSD’s Recycled Water System accepts approximately 500 million gallons per day of wastewater, which is sent to 11 wastewater treatment plants. The treated water is distributed throughout the recycled water distribution system.

LACSD has the capacity to process the wastewater planned under the General Plan Vision 2010, and this Project is consistent with the General Plan Vision 2010. The addition of the proposed Project will not significantly impact LACSD’s capacity, and impacts associated with wastewater treatment will be less than significant, directly, indirectly, and cumulatively.

All new development is required to comply with all provisions of the NPDES program and the City’s Municipal Separate Sewer Permit (MS4), as enforced by the Regional Water Quality Control Board (RWQCB). The Project is consistent with the General Plan proposing residential units. Compliance with the City’s, LACSD’s, all Waste Discharge Requirements outlined by the RWQCB, as well as requirements included in the NPDES permit, SWPPP, LID, and wastewater conveyance standards would ensure that wastewater discharges coming from the Project site and treated by the wastewater treatment facility system would not exceed applicable RWQCB wastewater treatment requirements or capacity.

Impacts would be less than significant with mitigation, directly, indirectly, or cumulatively.

Storm Water Drainage
The existing site is currently vacant, pervious land. Elevations onsite range between approximately 81 feet to 85 feet above mean sea level, with a relative low point near the site's northeast corner. Existing site drainage is generally directed as sheet flow in the northeast direction and overflows into the rightsof-way of West Compton Boulevard and South Kemp Avenue. Within West Compton Boulevard and South Kemp Avenue, two (2) existing catch basins capture and convey stormwater to an existing Los Angeles County Flood Control District (LACFCD) 66” storm drain facility within West Compton Boulevard, which flows in the easterly direction and outlets to the existing Compton Creek. Compton Creek drains to the existing Los Angeles River and ultimately the Pacific Ocean at San Pedro Bay.

Proposed site drainage will be collected and conveyed by two (2) proposed curb-inlet catch basins and an area drain system to two (2) proposed underground detention systems, which will discharge to the existing LACFCD 66” storm drain at two (2) points of connection. Low flows will be directed to proposed Concord Residential Project Page 70 City of Compton

Modular Wetlands System (MWS) Biofiltration Vaults for water quality treatment prior to entering the proposed detention systems. During larger storm events, stormwater runoff will bypass the treatment systems and be conveyed directly to the proposed detention system. The detention system will be equipped with an orifice to mitigate the peak discharge rate to the allowable peak flow rate (Allowable Q) provided by the Los Angeles County Department of Public Works (LACDPW). Excess flows will be temporarily detained as they are released at the Allowable Q. Refer to Appendix H of the Preliminary Hydrology and Hydraulics Study for the Allowable Q provided by LACFCD.

The Project will comply with the requirements of Chapter 31 – Runoff Pollution Control of the Municipal Code. As such, a Preliminary Low Impact Development (LID) Plan has been prepared consistent with the Los Angeles County Department of Public Works LID Manual and the intent of the NPDES stormwater requirements (State Water Resources Control Board (SWRCB) National Pollutant Discharge Elimination System (NPDES) General Permit for Storm Water Discharges Associated with Construction and Land Disturbance Activities, Order No. 2009-0009-DWQ, NPDES No. CAS000002, dated July 1, 2010.

The Project will not impact the existing stormwater management systems significantly. The Project will result in an incremental increase in the volume of stormwater; however, the City will require that the incremental increase in volume be managed on-site. The preparation of site-specific hydrology studies, water management plans, and Project design and compliance with existing federal, state, and local water quality laws and regulations related to water quality standards will ensure a less than significant impact, directly, indirectly, and cumulatively to stormwater facilities.

Electric Power
Electric power is provided to the site by Southern California Edison (SCE). The Project will utilize a 400- amp service for the 5-plex buildings and an 800-amp service for the 10-plex buildings. The services will be connected to existing 12kV 120/208, 3-phase distribution lines in West Compton Boulevard. SCE has committed to providing service to the planned uses of the General Plan, and this Project is consistent with the City’s General Plan. The Project will not require or result in the relocation or construction of new or expanded electric power, which could cause significant environmental effects. Therefore, the Project will have a less than significant effect on electric power expansion.

Natural Gas
The Project will not utilize natural gas. Southern California Gas Company has natural gas lines in West Compton Boulevard (four-inch) and within the adjacent streets (two-inch). The Project will not require or result in the relocation or construction of new or expanded natural gas facilities power, which could cause significant environmental effects. Therefore, the Project will have a less than significant effect on natural gas facility expansion.

Telecommunications Facilities
Both Charter and AT&T have lines on the existing 80-foot high poles along West Compton Boulevard.

These lines are to be protected in place. Therefore, the Project will have a less than significant effect on telecommunication facility expansion.

Summary
As noted above and in responses Section X and XIX b) above of this document, the Project will be less than significant directly, indirectly, or cumulatively, on the relocation or construction of new or expanded water, wastewater treatment or stormwater drainage, electric power, natural gas, or telecommunications facilities, the construction or relocation of which could cause significant environmental effects. b) Have sufficient water supplies available to serve
the project and reasonably foreseeable future
development during normal, dry, and multiple
dry years?

The Project proposes 60 townhomes; a water supply assessment from CMWD, the water purveyor, is not required.

As noted above, the water usage for the Project is consistent with the predicted use and growth identified in the UWMP, insofar as the CMWD based its planning on land use designations in its service district.

The Project will tie into existing domestic water lines in West 151st Street. No new wells or additional water infrastructure, or entitlements will be required.

The Project will be required to implement all water conservation measures imposed by CMWD under normal and drought conditions over the life of the Project. The Project will be required to implement any emergency measures in effect when the Project is developed.

As the Project is consistent with the General Plan Vision 2010 upon which CMWD has made their assumptions for planned water availability and compliance with all State and local regulations, impacts to water supplies will be less than significant, directly, indirectly, and cumulatively. c) Result in a determination by the wastewater
treatment provider which serves or may serve
the project that it has adequate capacity to
serve the project's projected demand in addition
to the provider's existing commitments?
Response:

See also response Section X and XIX a) above for additional information.

Sanitary sewage from the Project site will be connected to the existing 12-inch sanitary sewer line located in West Compton Boulevard through the new lines proposed within the newly created streets within the Project. The wastewater will then be transported to the Los Angeles County Sanitation District (LACSD) sewage system.

The Project will be served by the Los Angeles County Sanitation District (LACSD) sewer infrastructure.

C&V Consulting, Inc. has prepared a Sewer Area Study. The existing sewer system analyzed in the area study has a design capacity above the calculated cumulative flow. The peak discharge at the downstream end of the sewer system 15” pipe entering the County Sanitation District No. 1 existing 31.3” sewer trunk main is calculated to be a rate of 1.8465 cfs with a flow depth of 7.61 inches. Refer to Appendix B of the Sewer Area Study for calculations and tabulated results. Therefore, it is concluded that the existing sewer system has adequate capacity for the proposed development.

Wastewater in the City of Compton is collected by the LACSD sewage system and sent to one of eleven treatment or wastewater plants. At these plants, the wastewater goes through a three-stage treatment process consisting of primary, secondary, and tertiary treatment stages. After tertiary treatment, water is available for use to recycled water customers, use for groundwater recharge, or discharged into the ocean. Although the City of Compton is not part of a recycled water system, wastewater collected from the City is treated to recycled water standards and can be distributed through the LACSD’s recycled water supply system.

d) Generate solid waste in excess of State or local
standards, or in excess of the capacity of local
infrastructure, or otherwise impair the attainment of solid waste reduction goals? Response:

Republic Services will provide trash collection. Republic Services transports solid waste local transfer stations for recycling, with the non-recyclable waste disposed of at local landfills. With the implementation of the City’s and Republic Services recycling programs, the City continues to divert waste from the landfill. Therefore, landfill capacity is available to accommodate this Project, and the Project will have a less than significant impact, directly, indirectly, and cumulatively on landfills. e) Comply with federal, state, and local management and reduction statutes and regulations related to solid waste? Response:

Federal, State, and local statutes and regulations regarding solid waste generation, transport, and disposal are intended to assure adequate landfill capacity through mandatory reductions in solid waste quantities (for example, through recycling and composting of green waste) and the safe and efficient transportation of solid waste. The Project will comply with all regulatory requirements regarding solid waste, including AB 939 and AB 341. AB 939, which the California Department of Resources Recycling and Recovery administered, required local governments to achieve a landfill diversion rate of at least 50 percent by January 1, 2000, through source reduction, recycling, and composting activities. Moreover, AB 341 increases the minimum solid waste diversion rate to 75 percent by 2020. Such regulations will apply to this Project, and compliance is mandatory. Further, mandates set forth by the CALGreen Code aim to reduce solid waste generation and promote recycling and diversion design and activities, to which this Project is required to comply. There will be no impacts, directly, indirectly or cumulatively, regarding compliance with Federal, State, and local statutes and regulations related to solid waste.

The Project provides adequate access for emergency vehicles, including adequate street widths and vertical clearance on new streets. Implementation of federal, state, and local laws and regulations in this Project's construction ensures no impact on an adopted emergency response plan or evacuation plan.
b) Due to slope, prevailing winds, and other factors, exacerbate wildfire risks, and thereby expose project occupants to pollutant concentrations from a wildfire or the uncontrolled spread of a wildfire?
Response:

In addition to response Sections VII and IX above, the Project site is not located within a Very High Fire Hazard Classification area. As well, the site is relatively flat and surrounded by residential uses. Therefore, the Project will not exacerbate wildfire risks and will have no impact, directly, indirectly, or cumulatively, to the exposure of pollutant concentration from a wildfire or the uncontrolled spread of a wildfire. c) Require the installation or maintenance of associated infrastructure (such as roads, fuel breaks, emergency water sources, power lines,
or other utilities) that may exacerbate fire risk or
that may result in temporary or ongoing impacts
on the environment?
Response:

The Project will not require the installation or maintenance of the associated infrastructure that would exacerbate fire risk or that may result in temporary or ongoing impacts on the environment and as such, will have no impact, directly, indirectly, or cumulatively. d) Expose people or structures to significant risks,
including downslope or downstream flooding or
landslides, as a result of runoff, post-fire slope
instability, or drainage changes?
Response:

See Sections VII and IX above. The Project site is not located within a Very High Fire Hazard Classification area.

The site is situated on relatively level ground and is not immediately adjacent to any slopes or hillsides that could be potentially susceptible to slope instability. No signs of slope instability in the form of landslides, rockfalls, earth flows, or slumps were observed at or near the subject site during Sladden’s investigation.

The Project site is not located within a 100-year mapped flood zone (FEMA Flood Insurance Rate Map No. 06037C1815F (September 26, 2008). The Project would redirect on-site drainage patterns; however, it would not impede or redirect flood flows. As referenced, all drainage would be managed to ensure pre-construction flows off-site are maintained. The Project would not expose people or structures to flood hazards from severe storm events.

Therefore, the Project will have no impact, directly, indirectly, or cumulatively, as it is not expected to have a wildland fire on site and therefore, will not expose people or structures to significant risk from flooding or landslides as a result of a post-wildfire.

XXI. MANDATORY FINDINGS OF SIGNIFICANCE
a) 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 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?
Response:

In Section IV (Biological Resources), and Sections V (Cultural Resources), and XVIII (Tribal Cultural Resources), it is noted that the Project was once developed with a convalescent hospital and is surrounded by urban development. As such, the site does not provide biological habitat. Due to the previous ground disturbance, the Project will have no impact on biological resources or eliminate important examples of significant periods of California history or pre-history. b) Does the project have impacts that are individually limited, but cumulatively considerable? (“Cumulatively considerable” means that the incremental effects of a project are considerable when viewed in connection with the effects of
past projects, the effects of other current project, and the effects of probable future projects.)? Response:

The Project will contribute to the cumulative impacts of development in the City of Compton and the broader area. However, the Project is in conformance with the City’s General Plan, and therefore, it will have a less than significant impact cumulatively.
c) Does the project have environmental effects
which will cause substantial adverse effects on
human beings, either directly or indirectly?
Response:

Effects on human beings were evaluated as part of the Air Quality, Energy, Geology and Soils, Greenhouse Gas Emissions, Hazards, and Hazardous Materials, Hydrology and Water Quality, Land Use/Planning, Population and Housing, Public Services, Recreation, and Utilities sections of this Initial Study and were found to be less than significant for each of the above sections. The effects on human beings were evaluated as part of the Aesthetics, Noise, Transportation, and Wildfire sections of this Initial Study and were found to be less than significant with mitigation. Based on the analysis and conclusions in this Initial Study, the Project will not cause substantial adverse effects, directly or indirectly, to human beings. Therefore, potential direct and indirect impacts on human beings that result from the proposed Project are less than significant with mitigation measures MM AES-1, MM AES-2, MM NOI-1 through MM NOI-6, and MM TRAF-1 and MM TRAF-2.

Subject: Traffic & Parking Analysis: Compton & Kemp Residential Project – Supplemental Traffic Analysis
Dear Ms. Prijatel,
TJW ENGINEERING, INC. (TJW) is pleased to submit this supplemental traffic analysis for the proposed Compton & Kemp residential project in the City of Compton. The project site is bound by Compton Boulevard to the north, Kemp Avenue to the east, W 151st Street to the south and Dwight Avenue to the west. A Traffic Impact Analysis was completed for the project in September 2019. Since then, the proposed project has been modified from 24 single-family dwelling units to 60 multi-family dwelling units. This supplemental traffic analysis is to provide an overview of the modifications to the proposed project. The project is anticipated to be built and generating trips in 2022. Site access is planned at two driveways on W 151st Street. The Project’s site plan is shown in Exhibit 1.

All methodologies outlined in the September 2019 study are followed and utilized in this memorandum, including trip distribution. The 2019 peak turning movement volumes were used in this report and a 2% annual growth was applied to the 2019 data to establish the project baseline year for 2021.

Trip Generation Analysis
Table 1 shows the revised trip generation of the proposed project. Dwight Avenue at Compton Boulevard was the study intersection previously analyzed for its level of service which include the following study scenarios; project baseline year, opening year without project, and opening year with project. The proposed project’s anticipated trip generation has increased by 212 daily trips 10 AM peak hour trips and 10 PM peak hour trips from the September 2019 study.

Traffic Analysis – Level of Service (LOS)
Traffic volumes consist of (2019) traffic counts plus application of an annual ambient growth rate to establish the project baseline year, which in this case is (2021). The ambient growth rate used in this analysis is based on feedback provided on the scoping letter, which recommended a growth rate of 2% per year, applied for two years, to the (2019) traffic counts to account for ambient traffic growth.

Project baseline year traffic volumes (2021) = ((2019) traffic counts * 1.02^2) Project opening year traffic volume conditions include another 2.0 percent growth rate projected trips associated with ambient growth and any nearby cumulative projects, consistent with the September 2019 traffic impact analysis.

Project opening year traffic volumes (2022) = (project baseline year traffic volumes (2021* 1.02) The intersection analysis AM and PM peak hour results are shown in Table 2. ICU analysis sheets are attached to the Appendix for reference.

Table 2: Intersection Analysis
Note: ICU = Intersection Capacity Utilization. Delay shown in seconds for worst performing stop-controlled movement at driveways As shown in Table 2, the intersection is currently operating at an acceptable level of service for both AM and PM peak hours. The intersection is projected to continue to operate at an acceptable level of service during the AM and PM peak hours for project opening year (2022) without and with project conditions. Based on the City of Compton’s threshold of significance, the opening year with project (2022) conditions is not projected to have a significant impact at the study intersection.

Parking Analysis
The proposed project has been changed from 24 single-family dwelling units to 60 multi-family dwelling units.

Table 30.-21.A Parking Space Requirements in the City of Compton Zoning Code contains minimum parking requirements for various land uses in the City.

Condominiums and townhouses are required to provide two enclosed spaces per dwelling unit plus one guest space for every four units. The proposed project would be required to provide 120 enclosed parking spaces and 15 guest spaces. A total of 135 parking spaces are being proposed for the 60 multifamily dwelling units, meeting city parking code requirements.

As reported in the September 2019 study providing access to the proposed project will result in a loss of 6-8 on-street parking spaces on the north side of 151st Street between Dwight Avenue and Kemp Avenue due to the construction of two driveways with 6-feet of red curb on both sides of the driveways.

TJW collected on-street parking counts on the streets surrounding the project site in the afternoon and evening on Wednesday June 19th, 2019 from 4:00 PM to 12:00 AM to assess the existing parking inventory and occupancy. Evening hours were chosen since the overnight period is the peak period of parking demand for the residential uses adjacent to the site. Since the on-street parking supply is not striped, the inventory of each block face was projected based on observations in the field. And measurements of curb space.

The parking areas assessed were the south side of Compton Boulevard between Dwight Avenue and Kemp Avenue, both sides of Dwight Avenue between Compton Boulevard and 151St Street, both sides of 151st Street between Dwight Avenue and Kemp Avenue, and both sides Kemp Avenue between Compton Boulevard and 151st Street. A total of 94 on-street parking spaces were observed with a maximum demand of 61 vehicles (65 percent occupancy).

Although the project is expanding the number of dwelling units, the project will provide adequate parking per city parking code requirement. In addition, based on the parking data collection from the September 2019 report, there is adequate on-street parking availability nearby to accommodate any displacement from the loss of 6-8 on-street parking spaces on 151st Street.

VMT Analysis
Senate Bill (SB) 743 was adopted in 2013 requiring the Governor’s Office of Planning and Research (OPR) to identify new metrics for identifying and mitigating transportation impacts within the California Environmental Quality Act (CEQA). For land use projects, OPR has identified Vehicle Miles Traveled (VMT) as the new metric for transportation analysis under CEQA. The regulatory changes to the CEQA guidelines that implement SB 743 were approved on December 28th, 2018 with an implementation date of July 1st, 2020 as the new metric.

Coordination with City staff has identified the use of OPR's Technical Advisory on Evaluating Transportation Impacts in CEQA (2018). OPR's Technical Advisory document outlines the screening criteria, threshold of significance, and requirements for VMT assessment of land use projects. Outlined in the Technical Advisory, the VMT threshold of significance has been identified as fifteen (15) percent below existing residential VMT per capita. In addition, the document outlines a variety of acceptable mitigation measures. This memorandum utilizes the California Air Pollution Control Officers Association (CAPCOA) Qualifying Greenhouse Gas Mitigation Measures (2010) for purposes of mitigation and VMT reduction.

The project is surrounded by residential uses and will complement the adjacent area. Outlined in the CAPCOA document, travel demand measures are provided which can reduce a project's VMT. Of particular note, LUT01 references an increase in density and its impact to VMT; project's with increased densities reduces greenhouse gas emissions associated with traffic in several ways. Taking into consideration the proposed project's density and applying the LUT-01, the project's VMT can be reduced by 15.56% (Table 3, below). As the project's density can reduce the proposed project's VMT by 15.56% (greater than 15%), it is assumed the project will have a less than significant transportation impact.

1.0 EXECUTIVE SUMMARY

This traffic impact analysis (TIA) analyzes the projected traffic operations associated with the proposed Compton and Kemp Residential project in the City of Compton. The purpose of this TIA is to evaluate potential circulation system deficiencies that may result from development of the proposed project, and to recommend improvements to achieve acceptable operations, if applicable.

This analysis has been prepared pursuant to applicable City of Compton/Los Angeles County traffic impact analysis guidelines.

The proposed project is bounded by Compton Boulevard to the north, Kemp Avenue to the east, 151st Street to the south and Dwight Avenue to the west. The proposed project would consist of 24-single family dwelling units. The site, located at 930 West Compton Boulevard, is currently vacant. Site access is planned at two driveways on 151st Street.

The proposed project is anticipated to be built and generating trips in 2021.

The following signalized intersection in the vicinity of the project site has been included in the intersection level of service (LOS) analysis based on submission of a scoping letter and receipt of comments back from City staff.
• Dwight Avenue [runs north-south (NS)] at Compton Boulevard [runs east-west (EW)].

This traffic analysis follows the Los Angeles County Public Works Traffic Impact Analysis Report Guidelines (January 1, 1997).

1.1 SUMMARY OF ANALYSIS RESULTS
No significant impacts are projected in the study area as a result of the proposed project, based on the City of Compton’s thresholds of significance. Therefore, the proposed project should not be responsible for implementing any off-site improvements, except for improvements related to the project driveways.

The study intersection is projected to operate at an acceptable LOS (LOS D or better) for all analysis scenarios.

The proposed project will result in the loss of 6-8 on-street parking spaces on the north side of 151st Street between Dwight Avenue and Kemp Avenue based on California Manual on Uniform Traffic Control Devices (CA MUTCD) guidelines for urban driveways. There would still remain adequate onstreet parking capacity on the streets adjacent to the proposed project site. The proposed project satisfies minimum off-street parking requirements.
