6. Climate Risk Detailed Report

6.1. Climate Risk Summary
Cal-Adapt midcentury 2040–2059 average projections for four hazards are reported below for your project location. These are under Representation Concentration Pathway (RCP) 8.5 which assumes GHG emissions will continue to rise strongly through 2050 and then plateau around 2100.

Climate Hazard Result for Project Location Unit
Lawndale General Plan Update Detailed Report, 7/11/2023 287 / 293
Temperature and Extreme Heat 5.38 annual days of extreme heat Extreme Precipitation 4.70 annual days with precipitation above 20 mm Sea Level Rise 0.00 meters of inundation depth
Wildfire 0.00 annual hectares burned
Temperature and Extreme Heat data are for grid cell in which your project are located. The projection is based on the 98th historical percentile of daily maximum/minimum temperatures from observed historical data (32 climate model ensemble from Cal-Adapt, 2040–2059 average under RCP 8.5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Extreme Precipitation data are for the grid cell in which your project are located. The threshold of 20 mm is equivalent to about ¾ an inch of rain, which would be light to moderate rainfall if received over a full day or heavy rain if received over a period of 2 to 4 hours. Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Sea Level Rise data are for the grid cell in which your project are located. The projections are from Radke et al. (2017), as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider different increments of sea level rise coupled with extreme storm events. Users may select from four model simulations to view the range in potential inundation depth for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 50 meters (m) by 50 m, or about 164 feet (ft) by 164 ft.

Wildfire data are for the grid cell in which your project are located. The projections are from UC Davis, as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider historical data of climate, vegetation, population density, and large (> 400 ha) fire history. Users may select from four model simulations to view the range in potential wildfire probabilities for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

MANAGEMENT SUMMARY
DUKE Cultural Resources Management, LLC (DUKE C R M ) is under contract to De Novo Planning Group, to conduct a cultural and paleontological resources assessment for the Lawndale General Plan Update and Hawthorne Specific Plan Update (Project). The Project includes the City of Lawndale (City) and a length of Hawthorne Boulevard and limited side streets in total comprising approximately 1,260 acres.

The purpose of this report is to inventory the previously recorded paleontological and cultural resources in the City and Specific Plan area to assess the potential for impacts to these resources during implementation of the Project. This effort was completed in compliance with the California Environmental Quality Act (CEQA).

DUKE CRM requested paleontological records searches for the Project from the Natural History Museum of Los Angeles County and fossil localities within a three 3 mile radius were investigated on the online University of California Museum of Paleontology collections, Paleobiology Database, FAUNMAP, and other available published resources. Fossil localities have been recorded in deposits similar in age to those underlying the Project.

DUKE CRM requested a records search from the South Central Coastal Information Center (SCCIC).

Records from the SCCIC indicate that there are at least 12 built environment historic resources mapped within the City of which nine are listed in the Built Environment Resource Directory maintained by the State Office of Historic Preservation. No prehistoric or historic archaeological resources have been previously recorded in the Project boundaries. A city-wide reconnaissance resource survey was conducted. A combination of digital, windshield, and reconnaissance survey methods were employed. No cultural resources were recorded.

1 INTRODUCTION
DUKE Cultural Resources Management, LLC (DUKE C R M ) is under contract to De Novo Planning Group to conduct a cultural and paleontological resources assessment for the Lawndale General Plan Update and Hawthorne Boulevard Specific Plan Update Project (Project). The General Plan area consists of the City of Lawndale (City) comprising approximately 1,260 acres. The Hawthorne Boulevard Specific Plan is entirely within the General Plan and does not add any acreage to the General Plan. The purpose of this report is to inventory recorded paleontological, cultural, and historical resources in order to assess the potential for impacts to them during the implementation of the Project and to assist the City in managing these resources in their long term growth and development. This effort was completed in compliance with the California Environmental Quality Act (CEQA).

Project Location
The City of Lawndale is in the Los Angeles Basin situated approximately 26 miles southwest of downtown Los Angeles, and three miles from the Pacific Ocean (Appendix A, Map 1). Regional access is provided by the Interstate 405 (I-405), State Route 78 (SR 107), and SR 91. The City is located in the former Sausal Redondo Rancho in Township 3 south, Range 14 west in what would be sections 20, 21, and 28, as depicted on the USGS Torrance, Calif. 7.5 Minute Quadrangles (see Appendix A, Map 2). The central artery of the City is Hawthorne Boulevard. The Hawthorne Boulevard Specific Plan Update is located between Rosecrans Boulevard on the north and Redondo Beach Boulevard on the south. It also includes small segments of Redondo Beach Boulevard and other side streets. Generally, the area of the Project is nestled between the Cities of Hawthorne to the north, Redondo Beach to the west and south, and Torrance to the south and east. (Appendix A, Map 3).

Project Description
The project includes a comprehensive update to the City’s General Plan (1992) and the Hawthorne Boulevard Specific Plan (1999) goals and polices to assist the City with their long-term growth and development. A Program Environmental Impact Report will be prepared to analyze the potential impacts associated with implementation of the new General Plan and Specific Plan.

Cultural Resource: Cultural resources are tangible remains of past human activity. These may include buildings, structures, prehistoric and historic archaeological sites, historic or prehistoric objects, rock art, earthworks, canals, and landscapes. These nonrenewable resources may yield unique information about past societies and environments and provide answers for modern day social and conservation problems. A cultural resource is not necessarily significant and is not necessarily eligible for the California Register of Historical Resources (CRHR).

Historical Resource: A historical resource is defined as any cultural resource that is either listed in or determined eligible for the CRHR, included in a local register of historical resources, or identified as significant in a historical resources survey (CEQA, PRC § 21084.1), and can be any of the above-listed types of cultural resources.

Tribal Cultural Resource: Tribal Cultural Resources (TCRs) are defined as sites, features, places, cultural landscapes, sacred places, and objects with cultural value to a California Native American tribe that are either included or determined to be eligible for inclusion in the CRHR or included in a local register of historical resources, or a resource determined by the lead agency, in its discretion and supported by substantial evidence, to be significant (CEQA, PRC § 21074).

Paleontological Resource: The term paleontological resource refers to any fossilized remains, traces, or imprints of organisms, preserved in or on the earth's crust, that are of paleontological interest and that provide information about the history of life on earth (SVP 2019).

2 Regulatory Setting
State Regulations
California Environmental Quality Act of 1970, as amended The California Environmental Quality Act of 1970 (CEQA) is legislation that requires a Lead Agency to evaluate if a proposed project would have a significant adverse effect on the environment, including historical resources (defined above). CEQA Guidelines pertaining to historical resources (Section 15064.5(b)(1)) state that “A substantial adverse change in the significance of a historical resource means physical demolition, destruction, relocation, or alteration of the resource or its immediate surroundings such that the significance of an historical resource would be materially impaired”.

California Register of Historical Resources
The CRHR is the state-maintained list of cultural resources found to be historically significant. The CRHR is maintained by the California Department of Parks and Recreation. Much like the NRHP, the CRHR has four major criteria that a cultural resource must meet to be eligible for inclusion on the list:

1. Is associated with events that have made a significant contribution to the broad patterns of California’s history and cultural heritage;

2. Is associated with the lives of persons important in our past;

3. Embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of an important creative individual or possesses high artistic values; or,

4. Has yielded, or may be likely to yield, information important in prehistory or history.

To be considered eligible for the CRHR a historical resource should also possess integrity of location, design, setting, materials, workmanship, feeling and association. As used here, integrity is defined as the ability of a historical resource to convey its significance. To determine which of these factors are most important will depend on the property being evaluated and which particular CRHR criterion under which the resource is considered eligible for listing. The period of significance is the period of time in which significant events or themes occurred. Alterations and impacts that affect the period of significance and overall integrity of the resource and its eligibility for the CRHR.

Furthermore, CEQA requires the lead agency consider whether or not a project will significantly affect unique archaeological resources that may be ineligible for listing in the CRHR and to avoid these unique archaeological resources when possible or mitigate any effects to less than significant levels (PRC 21083.2). As stated by CEQA, a unique archaeological resource means an archaeological artifact, object, or site that clearly demonstrates with a high probability that it meets, without merely adding to the current body of knowledge, any of the following criteria:

1. Contains information needed to answer important scientific research questions and that there is a demonstrable public interest in that information.

2. Has a special and particular quality such as being the oldest of its type or the best available example of its type.

3. Is directly associated with a scientifically recognized important prehistoric or historic event or person.

Impacts to non-unique archaeological resources are generally not considered a significant environmental impact (PRC section 21083.2(a); CEQA Guidelines section 15064.5(c)(4).) However, if a non-unique archaeological resource qualifies as a TCR (PRC 21074(c); 21083.2(h)), further consideration of significant impacts is required.

In addition, excavation must be stopped whenever human remains are uncovered, and the county coroner must be called in to assess the remains (Section 15064.5[e] of the CEQA Guidelines). If the county coroner determines that the remains are those of a Native American, the Native American Heritage Commission (NAHC) must be contacted within 24 hours, and the provisions for treating or disposing of the remains and any associated grave goods as described in Section 15064.5 of the CEQA Guidelines must be followed.

3 California Historical Landmarks
California Historical Landmarks (CHLs) are buildings, structures, sites, or places that have been determined to have statewide historical significance. These resources are evaluated according to four criteria:

1. The first, last, only, or most significant of its type in the state or within a large geographic region (Northern, Central, or Southern California).

2. Associated with an individual or group having a profound influence on the history of California.

3. A prototype of, or an outstanding example of, a period, style, architectural movement or construction; or is one of the more notable works, or the best surviving work in a region, of a pioneer architect, designer, or master builder.

CHLs must also be approved for designation by the County Board of Supervisors or the City/Town Council in which the resource is located; must be recommended by the State Historical Resources Commission; and be officially designated by the Director of California State Parks. The effect of designation on a property or resource is:
• Limited protection against alteration or demolition. Environmental review may be required under CEQA if a property is threatened by a project. The relevant local planning agency should be contacted for more information.
• If the municipality or local government participates in the Mills Act Program, then a historic property owner may enter into a contract with the local assessor for property tax reduction. • Local building inspector must grant code alternative provided under the California Historical Building Code (CHBC). Registration will be recorded on the property deed. • Automatic listing in CRHR.
• Bronze plaque at site (underwritten by local sponsor) ordered through the California Office of Historic Preservation (OHP); highway directional sign available through local Department of Transportation (Caltrans) district office.

A designated CHL needs to have the written consent of the property owner, and the local government is given 60 days for comment on any application for designation prior to the State Historical Resources Commission considers the nomination.

California Points of Historic Interest
California Points of Historical Interest (CPHI) are sites, buildings, features, or events that are of local (City or County) significance and have anthropological, cultural, military, political, architectural, economic, scientific or technical, religious, experimental, or other value. CPHIs designated after December 1997 and recommended by the State Historical Resources Commission are also listed in the CRHR.

No resource may be designated as both a CHL and a CPHI. If a CPHI is subsequently granted status as a CHL, the CPHI designation will be retired. To be eligible for designation as a CPHI, a resource must meet at least one of the following criteria:

1. The first, last, only, or most significant of its type within the local geographic region (City or County).

2. Associated with an individual or group having a profound influence on the history of the local area.

3. A prototype of, or an outstanding example of, a period, style, architectural movement or construction or is one of the more notable works or the best surviving work in the local region of a pioneer architect, designer or master builder.

The effect of designation on a property or resource is:
• Limited protection against alteration or demolition. Environmental review may be required under CEQA if a property is threatened by a project. The relevant local planning agency should be contacted for more information.

DUKE Cultural Resources Management
4 • If the municipality or local government participates in the Mills Act Program, then a historic property owner may enter into a contract with the local assessor for property tax reduction. • Local building inspector must grant code alternative provided under State Historic Building Code.

Registration will be recorded on the property deed.

A designated CPHI needs to have the written consent of the property owner, and the local government is given 60 days for comment on any application for designation prior to the State Historical Resources Commission considers the nomination.

California Historical Building Code
The California Historical Building Code (CHBC) is defined by Sections 18950 to 18961 of Division 13, Part

2.7 of the Health and Safety Code. The CHBC provides guidelines and regulations for the preservation and contemporary use of historic structures and buildings that are considered “qualified historical buildings or structures.” The CHBC specifically provides alternative building regulations and guidelines for permitting repairs, alterations and additions necessary for preservation, rehabilitation, relocation, related construction, change of use, or continued use.

Section 8-201 of the CHBC (2016) defines a “qualified historical building or structure” as “any structure or property, collection of structures, and their associated sites deemed of importance to the history, architecture, or culture of an area by an appropriate local or state governmental jurisdiction. This includes structures on existing or future national, state or local historical registers or official inventories, such as the National Register of Historic Places (NRHP), CHL, CPHI, and city or county registers or inventories of historical or architecturally significant sites, places, historic districts, or landmarks.

Mills Act
The City of Lawndale authorized the creation of a Mills Act Program in 2010 for the preservation of historically significant properties. The Mills Act of 1972 is an economic incentive program by the State of California to encourage private property owners to restore and preserve qualified historic buildings. Local governments (Counties and Municipalities) can choose to implement and administer contracts with property owners to provide tax abatement, establish their own criteria for qualified historic buildings, and determine how many contracts they will allow in their jurisdiction. California State Codes relating to the Mills Act include the California Government Code, Article 12, Sections 50280 – 50290 and the California Revenue and Taxation Code, Article 1.9, Sections 439 – 439.4.

The Mills Act also known as the Historical Property Contract, is a formal agreement executed between the City of Lawndale and the property owner for a revolving, automatic ten-year term. Owners of qualified historic properties may apply for the program if they pledge to rehabilitate and maintain the historical and architectural character of their properties for the minimum ten-year life of the contract. A qualified historic property in the City of Lawndale is a property listed on the NRHP, the CRHR, or CHL.

Contracts are renewed each year so that the term of the contract can extend for ten years automatically.

Under this contract, property owners agree to restore, maintain, and protect the property in accordance with specific historic preservation standards and other conditions identified in the contract. Periodic inspections by City and County of Los Angeles officials ensure proper upkeep of the property to the standards included in the contract. Either the property owner or the City may elect not to renew for any reason. The effect of nonrenewal is to terminate the contract at the end of the current ten-year term. The owner may also petition the City to initiate an immediate cancellation. If cancelled, a penalty is imposed. The City may also cancel the contract, but only in the case of breach of the contract conditions. The contract is transferred to new owners if the property is sold and is binding to all successive owners.

Participation in the Mills Act is a benefit to qualified property owners, especially for recent buyers of historic properties but also for current owners of historic buildings who have made major improvements to their properties. An income approach to value rather than by the standard market approach determines the appraised value. The income approach, divided by a capitalization rate, determines the assessed value of the DUKE Cultural Resources Management
5 property. In general, the income potential for an owner-occupied residential property is calculated by examining comparable rents for similar properties in the area, while the income amount on a commercial property is based on actual rent received. Because rental values vary from area to area, actual property savings may vary. In addition, as counties are required to assess all property annually, Mills Act properties may realize slight increases in property taxes each year.

Senate Bill 18
Senate Bill 18 (SB 18) states that prior to the amendment or adoption of any general plan or specific plan or the designation of open space land proposed on or after March 1, 2005, the local or county government shall conduct consultation with California Native American tribes for the purpose of preserving or mitigating impacts to Cultural Places. A Cultural Place is defined as:
• Native American sanctified cemetery, place of worship, religious or ceremonial site, or sacred shrine (PRC 5097.9), or;
• Native American historic, cultural, or sacred site, that is listed or may be eligible for listing in the CRHR pursuant to Section 5024.1, including any historic or prehistoric ruins, any burial ground, or any archaeological or historic site (PRC Section 5067.995).

The intent of SB 18 is to establish “meaningful consultation” between tribal governments and local governments (government-to-government) at the earliest possible point in the planning process so that Cultural Places can be identified and preserved and to determine the necessary levels of confidentiality regarding Cultural Place locations and uses. SB 18 is not part of CEQA.

Assembly Bill 52
Assembly Bill 52 (AB 52) required an update to Appendix G (Initial Study Checklist) of the CEQA Guidelines to include questions related to impacts to TCRs. The law went into effect on July 1, 2015 with the changes to Appendix G approved on September 27, 2016. The Lead Agency would now also be charged with engaging with tribal governments at the earliest possible point in the planning process so that TCRs can be identified and preserved and to determine the necessary levels of confidentiality regarding TCR locations and uses.

Municipal Regulations
City of Lawndale General Plan 1992
The 1992 Lawndale General Plan addresses cultural resources in Chapter III, Resource Management, Section 2, Conservation Element. The addition of a conservation element is mandated under state government code section 65302(d). The overall purpose of Chapter 2 is to address increasing public concern for environmental quality, such as clean water and air, and the prevention and control of pollution, in light of growth and urbanization. The conservation element intends to:
• Promote the protection, maintenance and use of the state’s natural resources; • Prevent the wasteful exploitation, destruction, and neglect of the state’s natural resources; and • Recognize the natural resources must be maintained for the ecological value as well as for their direct benefits to the public.

The General Plan (1992:2-2) found that:
“The City of Lawndale is a highly urbanized area that functions primarily as bedroom community within the surrounding Los Angeles South Bay region. Because of the City’s high degree of urbanization, there are few natural resources remaining.” The General Plan (1992:2-5) identified several private residences that, at the time, were believed to be of “local historical interest”. Mentioned among these was the First Congregational Church at 4521 W. 147th Street built in 1906 and the first church in the City. No other historic in age (50+ years or older) civic or public structures were known to exist within the City. Importantly, it was asserted that in terms of potential significant residential development that:

DUKE Cultural Resources Management
6 “Many of the significant residential buildings were moved into Lawndale from other areas within the Los Angeles region. Many of these buildings are unknown and unrecognizable to the community because they are not located in one general area of the City, and many are concealed behind mature landscaping, or by remodeling that has ‘modernized’ or significantly customized their appearance.” (City of Lawndale 1992:2-5) The 1992 General Plan established Goal 4 for Cultural Resources:
“Promote the preservation and rehabilitation of cultural resources that are significant to the Lawndale community because of their age, architecture, history, or symbolism.” The City adopted six related policies for implementation of the above Goal:
• Policy 4a: Promote the preservation and/or conservation of historic structures, places, and or architectural features.
• Policy 4b: Investigate the appropriateness and feasibility of implementation a Historic Preservation Ordinance for the preservation of historic structures.
• Policy 4c: Investigate the feasibility of implementing a local historic registry program. • Policy 4d: Encourage the preservation of historic structures on their existing sites, or relocation if necessary and feasible.
• Policy 4e: Discourage the demolition or movement of historic structures without an evaluation of the condition of the structure, the cost of rehabilitation, and feasibility of preservation or conservation alternatives.
• Policy 4f: Encourage the adaptive re-use of historic structures.

The General Plan (1992) also details the implementation programs for cultural resources:
• 4.1 Historic Preservation: The City shall develop and implement a Historic Preservation Ordinance for the preservation of historic residences and structures. • 4.2 Historic Registry: Establish the feasibility of implementing a local historic registry program that provides incentives for retrofitting and maintenance, as well as public recognition, of the local resource.
• 4.3 Demolition Review: The City shall prohibit the demolition or movement of historic structures without an evaluation of the condition of the structure, the costs of rehabilitation, and the feasibility of preservation or conservation alternatives.

SETTING
The setting of the Project, composed of environmental, cultural, and historic backgrounds contextualize the findings of the current study. The Project covers 1,260 acres that overlap a limited number of geological, geomorphological, topographic components. Various other factors of the natural setting include water accessibility, climate, and broad patterns of soil development. The prehistoric, ethnographic and historical settings form the backdrop to human occupation of the Project. Each of the contextual elements to this study are considered below.

Geomorphological Setting
California is divided into 11 geomorphic provinces, each naturally defined by unique geologic and geomorphic characteristics. The Project is located on the western end of the Peninsular Ranges geomorphic province. The Peninsular Ranges province is distinguished by northwest trending mountain ranges and valleys following faults branching from the San Andreas Fault. The Peninsular Ranges are bound to the east by the Colorado Desert and extend north to the San Bernardino – Riverside County line (Norris and Webb 1976), west into the submarine continental shelf, and south to the California state line.

DUKE Cultural Resources Management
7 Locally, the City of Lawndale is located within the western end of the inland portion of the Los Angeles Basin, an actively subsiding basin bound by the Santa Monica and San Gabriel Mountains to the north, the Santa Ana Mountains to the east, and the Palos Verdes Hills to the south (Yerkes et al. 1965). The City is in the southwestern block of the Los Angeles Basin, which was the site of initial basin deformation, and is currently dominated by folded marine strata (Hauksson 1990). The geologic units underlying the Project record coastal and inland deposition during the Pleistocene Epoch (2.5 million years ago to 11,700 years ago).

Information regarding the specific geologic units and their paleontological sensitivity are discussed in detail in the results section of this report.

Environmental
The Project is broadly located within the Southern California/Northern Baja Coast region and it is composed of coastal and alluvial plains, marine terraces, and low hills within an area extending over 200 miles south into Baja California. The area has been largely cleared through overgrazing, agriculture and urban development.

Before these modern and historic processes occurred, coastal sage scrub and chaparral vegetation communities with many endemic species once were widespread. Plant species in coastal sage scrub communities includes coastal cholla, white sage, golden yarrow, California buckwheat, black sage, and chamise. The chaparral communities on the low hills include mountain-mahogany, ceanothus, manzanita, and scrub oak though stands of coast and canyon live oaks, poison oak, and black walnut can also be present.

Specifically, the Project is located within the Los Angeles Plain ecoregion. Ecoregions denote general similarity in ecosystems and environmental resources. Moist and cool marine air greatly moderates temperatures and rainfall in the Los Angeles Plain with annual precipitation ranging from 10 to 17 inches.

The ecoregion is nearly level with flat floodplains and terraces and very gently to gently sloping alluvial fans.

The soil temperature regime is thermic and soil moisture regime is xeric. Hydrology has been greatly modified and channelized. The Los Angeles River drains the San Fernando Valley and San Gabriel Mountains (Griffith et al. 2016).

Cultural
Prehistory
Of the many chronological sequences proposed for southern California, two primary regional syntheses are commonly used in the archaeological literature. The first, advanced by Wallace (1955), defines four cultural horizons for the southern California coastal province, each with characteristic local variations:

I. Early Man (~9000–8500 B.P.)
II. Milling Stone (8500–4000 B.P.)
III. Intermediate (4000–1500 B.P.)
IV. Late Prehistoric (1500~200 B.P.)
Warren (1968:1) chose instead to define “traditions” (La Jolla, Encinitas, Campbell, and Chumash, Yuman, or Shoshonean) that are “a generic unit comprising of historically related phases. Cultural traditions are identified and distinguished from one another on the basis of differences in cultural patterns reflected in differences in artifact types and assemblages and difference in cultural features”. While Warren (1968) keeps environment and cultural traditions distinct, his efforts marked that the relationship between them, through time was important for archaeological study. These two chronologies are still commonly used in tandem to discuss the chronology of southern California.

King (1990), in his work in the Santa Barbara Channel region, introduced yet another chronological scheme that was based on the seriation of shell beads and grave goods backed by radiocarbon dates. King’s chronology is divided into three periods, Early, Middle, and Late with date ranges for each. King’s chronology is widely used in the Santa Barbara region and has been heavily employed in the discussion of the nature of the emergence of social complexity on the southern California coast (Arnold 1992; Arnold and Munns 1994; Gamble 2005; Kennett and Kennett 2000; Raab and Larson 1997). King (1990) argued that correlations can be made between the physical characteristics of beads and the social contexts in which they were used. King DUKE Cultural Resources Management
8 analyzed beads and other artifacts, in addition to mortuary practices to demonstrate that changes in material culture reflect changes in society.

The works of Wallace (1955), Warren (1968) and King (1990) reflect a variety of methods to develop temporal sequences for describing archaeological remains. Refinements in methods, specifically the application of radiocarbon dating has significantly improved chronology building. In addition, applying successful models used in other regions, such as King’s (1990) application of the Bennyhoff and Hughes (1987) method of shell bead seriation to the southern California region has aided in the refinement of chronology building for the region. Complications such as the timing of the adaptation of “marker” artifact types, arise when broad regional chronologies are applied to small local areas that do not fit neatly into large macro schemes. Likewise, the subtle, yet significant nuances of local , micro-chronologies often complicate attempts to create a simple chronology that can be applied to a large region, such as southern California.

The project is located within the boundaries of Gabrielino or Tongva Indians. The Gabrielino Indians are named because of their association with the Mission San Gabriel Arcángel. The Gabrielino are one of the least known Native American groups in California. Generally, their territory included all of the Los Angeles Basin, parts of the Santa Ana and Santa Monica Mountains, along the coast from Aliso Creek in the south to Topanga Canyon in the north, and San Clemente, San Nicolas, and Santa Catalina Islands.

The Gabrielino spoke a dialect of the Cupan group of the Takic language family. This language was part of the larger Uto-Aztecan language stock which migrated west from the Great Basin. The Gabrielino shared this language with their neighboring groups to the south and east (Bean and Smith 1978, Shipley 1978).

Groups of Gabrielino lived in villages that were autonomous from other villages. Each village had access to hunting, collecting, and fishing areas (Bean and Smith 1978). Villages were typically located in protected coves or canyons near water. Acorns were the most important food for the Gabrielino, although the types and quantity of different foods varied by season and locale. Other important sources of food were grass and many other seed types, deer, rabbit, jackrabbit, woodrat, mice, ground squirrels, quail, doves, ducks and other fowl, fish, shellfish, and marine mammals.

Typically, Gabrielino women gathered and men hunted, although work tasks often overlapped. Each village had a chief who controlled religious, economic, and warfare authorities. The chief had an assistant and an advisory council who assisted in important decisions and rituals. Each of these positions was hereditary being passed down from generation to generation (Bean and Smith 1978). According to mapping of Gabrielino villages undertaken by McCawley (1996), no known villages would be located with the City. The two nearest Gabrielino villages, which may compose large areas rather than just a single location, are Swaanga approximately 10 miles to the southeast and Waachnga approximately five miles to the northwest (McCawley 1996:Map 8). The Kirkman-Harriman Pictorial and Historical Map of Los Angeles (1938) also does not identify any Gabrielino villages within the City.

History
In California, the historic era is generally divided into three periods: the Spanish or Mission Period (1769 to 1821), the Mexican or Rancho Period (1821 to 1848), and the American Period (1848 to present). The first Europeans in California were the Spanish. In 1542 Juan Rodriguez Cabrillo entered what was to become known as San Diego Harbor (Rolle 2003) where he met a group of Kumeyaay Indians while on shore. Over the next few hundred years there were several maritime excursions along the California coast, but it would be more than 225 years until the Spanish established a permanent settlement. To protect its interests, Spain sent four excursions into California, two by land and two by sea. The entire expedition was led by Captain Gaspar de Portolá, military commander of California (Rolle 2003). Portolá came through the Los Angeles basin area in 1769 while travelling from San Diego to Monterey. To fulfill some of the religious goals of the expedition Father Junípero Serra was sent to California to establish a system of Catholic Missions. It was not until two years later on September 8, 1771 that Mission San Gabriel Arcángel was established by Fathers Pedro Cambon and Angel Somera (Hoover et al. 1990).

DUKE Cultural Resources Management
9 Ten years later on September 4, 1781, Los Angeles was founded. Early settlers farmed and they built a system of zanjas, or irrigation ditches, to transport water from the Los Angeles River to plots of land. With Mexican Independence in 1821, Los Angeles and California experienced great economic independence and growth (Rolle 2003). By 1822, the Mexican government began to grant permits to its citizens along the southern coast for animal pasture. Governor of Alta California, Juan Alvarado, gave the Rancho Sausal Redondo land grant to Antonio Ignacio Ávila, son of Spanish soldier Cornelio Ávila, that encompassed the present-day cities of Lawndale, Inglewood, Hawthorne, Redondo Beach, Manhattan Beach, and Hermosa Beach. The total acreage of the land grant was roughly 40,000 acres; but when the United States Land Commission confirmed title, Rancho Sausal Redondo was reduced to 22,000 acres. The City of Lawndale is located in what was the southwestern corner of Rancho Sausal Redondo. Between 1820 and 1841 the population of Los Angeles tripled to 1,680. California was ceded to the U.S. in 1848 with the signing of the Treaty of Guadalupe Hidalgo (City of Lawndale 2020).

The Treaty of Guadalupe Hidalgo assured owners that prior, valid land grants would be honored if a claim was filed as required by the Land Act of 1851. Soon after, Antonio Ignacio Ávila filed a claim for Rancho Sausal Redondo and was awarded a patent in 1855 by the Public Land Commission. He later died in 1858 and his heirs sold the Rancho to pay for the probate costs. In 1868, ten years after his death, a Scottish nobleman named Sir Robert Burnett purchased the land grant from Ávila’s heirs. Having also acquired the Aquaje de la Centinela parcel, Burnett combined both areas and named it Centinela Ranch. After doing so, Burnett gradually slowed cattle ranching and began to incorporate his prior specialization of sheep raising. In 1873, Burnett leased Centinela Ranch to Daniel and Catherine Freeman and retuned to his home in Scotland. The Freeman’s continued to raise sheep but after a tumultuous two-year drought from 1875-1876, they began to plant barley along with several thousand citrus, almond, olive, and eucalyptus trees. The Freeman’s made dryland farming profitable and exported 3,000,000 bushels of barley and other crops to Liverpool and London well in to the 1880’s (City of Lawndale 2020).

The history of what later would be Lawndale begins with the opening of the Redondo seaport in 1890 and the railroad service created between the port and Los Angeles. By 1902, the Los Angeles and Redondo railways passed along in what is now Hawthorne Boulevard, extending from Inglewood to Railroad Avenue.

In March of 1905, real estate developer Charles B. Hopper subdivided and opened the southern portion of Centinela Ranch and named it Lawndale. It was marketed as an ideal poultry farming location for early settlers, but unfortunately a lack of buyers forced Hopper to change to smaller lots a year later. When the US Census was taken in 1910, the unincorporated town of Lawndale had already reached 142 residents. In the 1920’s the discovery of oil transformed the Lawndale community into a town that built oil derricks, though the Great Depression muted this economic development. After WWII, Lawndale boomed primarily due to subsidized veteran housing and increased accessibility of the Harbor Freeway. Also, the Businessman’s Group Association created zoning policies to promote and advertise the residential, commercial, and industrial advantages of Lawndale. Amid rapid commercial growth and urbanization of the Centinela Valley in 1958, zoning restrictions officially abolished agriculture in the community. On December 28, 1959, Lawndale was incorporated as a City in Los Angeles County, but long had a unique history and character (City of Lawndale 2020).

METHODS
The focus and purpose of this report are to support the CEQA process as part of the Project and, therefore are broad and programmatic in scope. Baseline paleontological, archaeological and historical data was compiled from record searches at various research facilities and online. Multiple survey methods, including desktop and field reconnaissance, were employed. Survey was limited due to lack of access to resources on private property and the shutdown of the Hawthorne Historical Society due to the Novel Coronavirus Pandemic. Research was also limited due to the same pandemic. The South Central Coastal Information at California State University, Fullerton was only able to respond with partial information as not all records are digital and therefore accessible.

10 Paleontological Resources Records Search
The geology of the Lawndale area has been mapped by Saucedo and others (2016) at a scale of 1:100,000. A paleontological records search were requested from the Natural History Museum of Los Angeles County (LACM). Fossil localities within 3 miles of the Project were investigated by DUKE CRM using the online University of California Museum of Paleontology collections, Paleobiology Database, FAUNMAP, and other published resources (Miller 1971; Jefferson 1991a, b). Additional background research was conducted in the Journal of Vertebrate Paleontology.

Cultural Resources Records Search
On April 9, 2020, Nicholas F. Hearth of DUKE C R M requested a records search at the South Central Coastal Information Center (SCCIC). The SCCIC provided the records search results on June 9, 2020. The SCCIC is part of the California Historical Resources Information System (CHRIS) and is located at California State University, Fullerton. The SCCIC records search included a review of all recorded historic and prehistoric archaeological sites within the City including the California OHP’s Historic Resources Inventory (HRI) directory, as well as a review of known cultural resource survey and excavation reports. The California State Historic Property Data File (HPDF) was examined, which includes the NRHP, CRHR, CHL, and CPHI. The Built Environment Resource Directory (BERD) was also consulted.

Research
Throughout the course of the Project, research was conducted in an effort to assess cultural sensitivity and focus field efforts. This included both published and unpublished materials. The following online resources were reviewed:
• Historic aerial photos and maps

On April 29, 2020, a combination of reconnaissance and pedestrian archaeological and historic resource field survey was performed within the City. Survey efforts attempted to relocate potential resources that were generally indicated upon the 1992 General Plan Update for the City. Access to these potential resources was through public roads. The resources’ status was determined by the presence/absence of appearance of a potential historic built environment resource, and/or basic level of development and.

RESULTS
Paleontological Resources Records Search
The City of Lawndale is underlain by two geologic units. Individual units, and their paleontological sensitivity, are described below.

Old alluvium, undivided (Qoa)
Old alluvium underlies the majority of the Project. It is composed of moderately well-consolidated, poorlysorted, permeable, slightly dissected gravel, sand, silt, and clay. These sediments were deposited on canyon floors by fluvial activity in the late to middle Pleistocene Epoch (Saucedo et al. 2016).

Old eolian deposits (Qoe)
Old eolian deposits underlie the northwest and southwest corners of the Project. It is composed of poorly consolidated, dense to very dense, well-sorted, fine- to coarse-grained sand and silty sand. These sediments were deposited as eolian coastal dunes in the late to middle Pleistocene (Saucedo et al. 2016) but the dune formation processes are now inactive (Poland et al. 1959).

The climate of Southern California during the Pleistocene was cooler and moister than the modern Mediterranean climate (Lamb 1989). In contrast to the harsh, cold conditions in high latitudes near the ice sheets, Southern California experienced a relatively milder climate during this time (Calder 1983). During this time, the area was inhabited by the familiar Pleistocene or “Ice Age” fauna, such as mammoth, mastodons, horses, camelids, and ground sloths (Stock 2001).

Deposits from the Pleistocene Epoch have not produced any fossil localities within the Project, but have produced two fossil localities within 3 miles:
• The “Mobile Oil Refinery” locality produced cetacean (whale) and Equus (horse) material from two miles southeast of the Project (Jefferson 1991b) and • Locality LACM 2035 produced Mammuthus columbi (Columbian mammoth) on 139th St, one mile north of the Project (Miller 1971).

Due to fossil material being previously discovered in deposits from the Pleistocene Epoch in vicinity of the Project, both old alluvium and old eolian deposits have a high paleontological sensitivity at the surface and at depth.

All historic built environment resources are located within the City surrounded by paved asphalt parking lots, commercial buildings, and single-family residential homes. None of the resources were accompanied by any historic archaeological deposits. Nor were any prehistoric cultural resources identified. The records of three built environment resources were provided by the SCCIC, below is a brief description of three of the historic built environment resources within the City.

P-19-188892
Resource P-19-188892 is the Lawndale High School Campus complex. First constructed in 1959, it was built to accommodate the postwar growing population needs of the newly founded City of Lawndale. The core campus consists of an administration building, a cafeteria, classroom buildings, support buildings, athletic fields, and a parking lot (McKenna et al. 2010). The original campus was a series of one- and two-story brick and cinder block buildings with low pitched roofs constructed on concrete pads. Windows consisted of steel framed fixed and casements. The campus complex was recommended not historically significant (McKenna et al. 2010).

P-19-188893
Resource P-19-188893 is the Leuzinger High School complex. It is the earliest high school built in the City in 1930, shortly after the Great Depression. It consisted of a main administration building, a cafeteria, an Olympian gym and a classroom building. It was named in honor of Adolph Leuzinger, who was a member of the Inglewood Union High School District Board of Trustees for 25 consecutive years. The campus was later expanded in 1956 with the addition of a new cafeteria, locker rooms north of the Olympic gymnasium, and classroom buildings 2, 3, 4, and 5 (McKenna el al. 2011). By 1976, a locker room, the Thompson gym, and DUKE Cultural Resources Management
13 classroom buildings 6, 7, and 8 (McKenna et al. 2011) had been added. Leuzinger High School was recommended to be considered a significant cultural resource under CEQA, therefore qualifies as a historical resource eligible for listing in the CRHR. Additionally, it was recommended that any additional alterations or demolition to the Olympic Gymnasium and/or Memorial Garden be avoided while any alterations to the interior of the Main Administration Building be kept to a minimum (McKenna et al. 2011).

P-19-190021
Located in a commercial zone in the City of Lawndale, 16720 Hawthorne Boulevard is a two-story retail building and a 10-vehicle parking lot first constructed in 1947. Designated as Tract 8293, Lot Number 106 and 107, this 6,000 square foot retail building measures roughly 50 feet wide by 105 feet long. Much of the construction is reinforced masonry on a concrete foundation and clad with stucco (Johnson 2012). The building has a flat roof covered with asphalt and gravel. The roof has a stepped parapet and fenestration that consists of an enframed window wall on the front with metal frames that span the length of the building.

There are no records of the original site plan or building permit, however, by 1970 a building permit indicates that the building was used for office space by the Mattel Toymakers Federal Credit Union (Johnson 2012). By 2003, building permits show the building was remodeled with the addition of a bathroom, a storefront, and stairs, as well as the demolition of a partition wall. The property does not appear to qualify for the NRHP (Johnson 2012).

Cultural Resource Studies
Based on the research from the SCCIC, five cultural resources studies have been completed in the Project area. Cultural resource studies date from 1991 to the present. Most of these projects relate to upgrading development of a highway, water reclamation and the Leuzinger High School. The bibliography from the SCCIC for cultural resource studies within the City is provided in Appendix C.

Additional Research
Supplemental additional research was conducted referencing online resources of maps, land grants, and aerial photographs. The earliest map of the Lawndale area found during research is a circa 1840s Diseño del Rancho Sausal Redondo that depicts a not-to-scale corral, mountain ranges to the west, and a broad flat area for the majority of the diseño (Calisphere 2011). The location of the Project is unclear due to the mapping inaccuracies common with diseño sketches.

General Land Office (GLO) plat maps of the area from original and supplemental survey dating from 1869 was reviewed for historic land ownership information and other pertinent historical locations within the Project (GLO 1869). Most of the Project is within Township 3 south, Range 14 west, and if plotted what would be Sections 21 and 28 though a small portion is in Section 20. The entire Project was plotted as within the Rancho Sausal Redondo and no features within the Rancho were mapped. It was noted that “George Harrison’s survey of the Sausal Redondo was decided to be the correct survey by the Secretary of the Interior, October 31, 1871”. Data was on file for the 1858 Mexican Land Grant Survey and the 1875 State of California Survey, but no plat images were available. No other GLO plat maps were available.

A minimum level of development consisting of widely spaced roads, is indicated in the Project on the 1880 map of the Los Angeles Basin (Rumsey Map 2020). Historic USGS maps of the City date from 1896 through the modern era as late as 1981 (USGS 2020). The following maps were reviewed:
• Redondo, Calif. 7.5 minute (1:24,000 scale), 1896;
• Torrance, Calif. 7.5 minute (1:24,000 scale), 1924, 1934; • Inglewood, Calif. 7.5 minute (1:24,000 scale), 1950, 1952, 1964, 1972, and 1981; • Southern California Map Sheet No. 1. (1:250,000 scale), 1901, 1904; and • Long Beach, California (1:250,000 scale), 1949, 1957, 1960.

These maps track the growth of the Lawndale area over late 19th through the 20th century. The late 19th and early 20th century maps indicate the area that would later become the City of Lawndale is rural and largely devoid of roads even, except around its borders. The 1924 Torrance, Calif. Map covers most of the Project and DUKE Cultural Resources Management
14 indicates that the area is known as Lawndale. Approximately 100 structures including what likely are residences, a school and a rail line are indicated though in essence the area indicate as Lawndale retains a largely rural character. The 1934 version of the same map indicates a greater number of structures, especially in the southern end of the Project, but the rural character is largely retained due to the low density of the development. The single school on this later map shows that it has been moved to the center of town. A single 1938 aerial image (UCSB) indicated an even greater level of development than the 1934 USGS.

By the mid-20th century, USGS maps and many aerial photographs are available to consult (UCSB 2020).

Urban levels of development of Lawndale dates to the mid-20th century as show on maps and aerial photography. A major transportation-related development is Highway 405, which is apparent on maps by 1957. The nearly complete urbanization is evident by the 1964 USGS maps.

Cultural Resources Field Survey
On April 29, 2020, a reconnaissance-level overview of the City was conducted by Nicholas F. Hearth of DUKE CRM. Reconnaissance survey consisted of surveying the City to get a general sense of the potential for the historical nature and visits to locations of built environment resources indicated in the previous General Plan (City of Lawndale 1992:Figure B). Revisits to site and resource locations were cursorial in effort.

The goal was to determine if the resource was present and if the surrounding area of the resource has been disturbed. Photographs were taken, and field notes were taken to document the findings. The reconnaissancelevel survey of the City revealed that land use within Lawndale is predominantly residential though commercial development is also present especially along Hawthorne Boulevard, see Figures 2-4.

A total of 12 built environment resources have been previously recorded within the City and are on-file with the SCCIC and BERD. In the City’s (1992:Figure B) General Plan 32 locations of historic structures were indicated. Of these 32 locations, 17 were visited during the field survey, see Table 3, and Figures 5 - 10. The remaining 15 historic structures noted in the 1992 General Plan appear to be removed or are so altered as to be unrecognizable.

RECOMMENDATIONS
The unique environment, events, people, and places of Lawndale have shaped its history, archaeology and paleontology. The traces of these events, people, and places are cultural and paleontological resources that are the physical remains of past activities. DUKE CRM recommends compliance with CEQA that requires a Lead Agency to evaluate if a proposed project would have a significant adverse effect on the environment, including historical resources. CEQA Guidelines pertaining to historical resources (Section 15064.5(b)(1)) state that “A substantial adverse change in the significance of a historical resource means physical demolition, destruction, relocation, or alteration of the resource or its immediate surroundings such that the significance of an historical resource would be materially impaired”. The following recommendations build on the previous goals and policies regarding the treatment of paleontological, archaeological, and historic resources.

Historic Resources
Historic built environment resources are the tangible evidence of past human activity, but are limited to buildings, structures, objects, linear features such as railroads or canals, and other types of earthworks. Twelve built environment resources are recorded at the SCCIC and in the BERD. The City’s 1992 General Plan lists 32 historic structures. Through the reconnaissance survey it was determined 17 of the 32 structures are extant, the remaining 15 have either been demolished or are so disturbed so as to be unrecognizable. Four of these 17 were also listed at the SCCIC/BERD bringing the total historic structures recorded in the City to 25.

None are listed on the NRHP or CRHR. The following recommendations for built environment resources should be applied to all projects conducted within the jurisdiction of the City of Lawndale.

1. If there is a building/structure that is 50 years or older, it should be evaluated for significance and eligibility for the CRHR.

2. If the building/structure is eligible for the CRHR preservation is the preferred treatment.

3. If preservation is not accomplished, minimization of impacts is recommended.

4. Mitigation of impacts is recommended for any impacts to historical resources, DUKE Cultural Resources Management
20 Archaeological Resources
Archaeological resources are tangible remains of past human activity. These may include prehistoric and historic sites, artifacts, rock art, ruins, features, and landscapes. These nonrenewable resources may yield unique information about past societies and environments, and provide answers for modern day social and conservation problems. Within the City, no archaeological resources are previously recorded. This situation seems highly likely to be a consequence of development occurring prior to the implementation of CEQA, rather than a lack of archaeological sites. The following recommendations for archaeological resources should be applied to all projects conducted within the jurisdiction of the City of Lawndale.

1. The project/property should be reviewed for archaeological sensitivity. This will involve a qualified archaeologist reviewing geology and soils reports and maps, historic maps, and as-built plans of the project/property.

2. The qualified archaeologist should make a recommendation of high, moderate, low, or no sensitivity for archaeological resources.

3. In areas of high sensitivity, buried sites testing is recommended prior to construction. Alternatively, full-time monitoring could be implemented during construction activities. In any event, if an archaeological site is discovered it should be evaluated/excavated to determine significance, this would include artifact analysis, interpretation, and a technical report. If the site is significant, preservation is the preferred treatment. If preservation is not accomplished, then treatment and/or mitigation of the site would be required.

4. In areas of moderate sensitivity, part-time monitoring during construction activities is recommended.

If an archaeological site is discovered it should be evaluated/excavated to determine significance, this would include artifact analysis, interpretation, and a technical report. If the site is significant, preservation is the preferred treatment. If preservation is not accomplished, then treatment and/or mitigation of the site would be required.

5. In areas of low sensitivity, spot-check monitoring during construction activities is recommended. If an archaeological site is discovered it should be evaluated/excavated to determine significance, this would include artifact analysis, interpretation, and a technical report. If the site is significant, preservation is the preferred treatment. If preservation is not accomplished, then treatment and/or mitigation of the site would be required.

6. In areas of no sensitivity, no monitoring during construction activities is recommended. If an archaeological site is discovered a qualified archaeologist should be retained to evaluate/excavate the site to determine significance, this would include artifact analysis, interpretation, and a technical report. If the site is significant, preservation is the preferred treatment. If preservation is not accomplished, then treatment and/or mitigation of the site would be required.

A qualified archaeologist is a person with a M.A. in anthropology or archaeology (or closely related filed) with at least one year of full-time professional experience in the field of archaeology, who has completed a supervised field school, who possess a demonstrated ability to conduct research to completion, and who maintains one year in a supervisory level in archaeological study; and/or who is a Registered Professional Archaeologist (RPA).

Paleontological Resources
The paleontological resources research indicates that the geologic formations in the City are known to contain paleontological localities with rare, well-preserved fossil materials that offer important information about the plant or animal and/or its evolutionary history. Both formations have been determined to be highly sensitive for paleontological resources. These important resources are most often destroyed as a result of construction, such as excavation, trenching, and tunneling. Impacts can be mitigated through preconstruction and construction mitigation programs. The following recommendations for paleontological resources should be applied to all projects conducted within the jurisdiction of the City of Lawndale.

1. The project/property should be reviewed for paleontological sensitivity. This will involve a qualified paleontologist reviewing geology and soils reports and maps, historic maps, and as-built plans of the project/property.

DUKE Cultural Resources Management
21 2. The qualified paleontologist should make a recommendation of high, moderate, low, or no sensitivity for paleontological resources.

3. In areas of high sensitivity, full-time monitoring should be implemented during construction activities. If a paleontological site is discovered it should be evaluated/excavated to determine significance. If it is significant, preservation is the preferred treatment. If preservation is not accomplished, then treatment and/or mitigation of the fossil would be required.

4. In areas of moderate sensitivity, part-time monitoring should be implemented during construction activities. If a paleontological site is discovered, it should be evaluated/excavated to determine significance. If it is significant, preservation is the preferred treatment. If preservation is not accomplished, then treatment and/or mitigation of the fossil would be required.

5. In areas of low sensitivity, spot-check monitoring should be implemented during construction activities. If a paleontological site is discovered, it should be evaluated/excavated to determine significance. If it is significant, preservation is the preferred treatment. If preservation is not accomplished, then treatment and/or mitigation of the fossil would be required.

6. In areas of no sensitivity, no monitoring during construction activities is recommended. If a paleontological site is discovered, a qualified paleontologist should be retained to evaluate/excavate the discovery to determine significance. If it is significant, preservation is the preferred treatment. If preservation is not accomplished, then treatment and/or mitigation of the fossil would be required.

A qualified paleontologist is a person with a B.S. or B.A. in geology, or closely related discipline with an emphasis in paleontology and demonstrated experience and competence in paleontological research, fieldwork, reporting, and curation.

CONCLUSIONS
DUKE CRM has conducted a cultural (archaeological and historical) and paleontological resources assessment for Project for the City, comprising approximately 1,260 acres. The purpose of this report is to inventory the previously recorded paleontological and cultural resources in the City, to assess the potential for impacts to these resources during implementation of the Project. This effort was completed in compliance with the CEQA.

DUKE CRM requested cultural and paleontological records searches. There are at least 12 cultural resources mapped within the City and all are historic built environment resources. No historic or prehistoric archaeological resources have been previously recorded within the City. Additionally, fossil localities have not been recorded in the City. The entire City is underlain by Pleistocene-age alluvium and Pleistocene-age eolian deposits that are considered to have a high sensitivity for paleontological resources due to the discovery of these resources near the City in similar deposits.

DUKE CRM recommends compliance with the resource management regulations in CEQA. Tribal Cultural Resources are recommended to be added to the City’s categories of cultural resources which reflect changes to CEQA.

1 1.0 Introduction

1.1 Purpose of Analysis and Study Objectives
This noise assessment was prepared to evaluate the potential noise impacts for the Project Area and to recommend noise mitigation measures, if necessary, to minimize the potential noise impacts. The assessment was conducted and compared to the noise standards set forth by the Federal, State, and Local agencies. Consistent with the City’s Noise Guidelines, the Project must demonstrate compliance to the applicable noise criterion as outlined within the City’s existing Noise Element and proposed Public Safety Element and Municipal Code.

The following is provided in this report:
 A description of the Project Area and the proposed Project  Information regarding the fundamentals of noise and vibration  A description of the local noise and vibration guidelines and standards  An analysis of traffic noise impacts to and from the project site  An analysis of stationary noise impacts to and from the project site  An analysis of construction noise impacts
 An analysis of ground-borne vibration impacts to and from the project site  Suggested mitigation measures to reduce impacts

1.2 Site Location and Project Area
The City of Lawndale is located in the South Bay area of Los Angeles County, approximately 10 miles southwest of downtown Los Angeles. The City is approximately 1.9 square miles (1,241 acres) and is bounded by the City of Hawthorne to the north and west, by unincorporated areas of Los Angeles County and the City of Gardena to the east, by the City of Torrance to the south, and by the City of Redondo Beach to the south and west. Regional access to the City is provided by Interstate 405, a major northsouth highway which provides access to Lawndale and the greater Los Angeles region.

The General Plan Update Study Area, as shown in Exhibit A, includes the entire City limits (approximately 1,241 acres) as well as the City of Lawndale’s Sphere of Influence (approximately 314 acres); the entire Study Area is approximately 1,555 acres.

1.3 Proposed Project Description
The City of Lawndale is preparing a comprehensive update to its existing General Plan. The updated Lawndale General Plan is expected to be adopted in 2023 and will guide the City’s development, growth, and conservation through land use objectives and policy guidance. The General Plan Update is intended to be an expression of the community’s vision for the City and Study Area, and constitutes the policy and regulatory framework by which future development projects will be reviewed, and public improvements will be implemented. The City will implement the General Plan Update by requiring development, infrastructure improvements, and other projects to be consistent with its policies and by implementing the actions included in the General Plan Update.

General Plan Update
Noise Impact Study
City of Lawndale, CA Introduction
2 This report will aid in the development of the noise portion of the Public Safety Element of the General Plan Update. The Public Safety Element establishes goals, policies, and actions to protect the community from risk associated with geologic, fire, and flood hazards, as well as setting standards for emergency preparedness. The Public Safety Element supports the City’s participation in the Lawndale Local Hazard Mitigation Plan, the County of Los Angeles All-Hazards Mitigation Plan, and the Lawndale Climate Action Plan. This Element also addresses the required topics related to noise, including standards and policies to protect the community from the harmful and annoying effects of exposure to excessive noise levels.

This Element includes strategies to reduce land use conflicts that may result in exposure to unacceptable noise levels.

1.4 General Plan Update Buildout Assumptions
Buildout of the General Plan could yield a total of up to 15,405 housing units, a population of 47,430 people, approximately 5.35 million square feet of non-residential building square footage, and 9,208 jobs within the Planning Area. As shown in Table 1, this represents development growth over existing conditions of up to approximately 3,942 new housing units, 9,482 people, 808,864 square feet of new non-residential building square footage, and 738 jobs.

The analysis of the General Plan Update is based on various assumptions regarding existing and future conditions in Lawndale. Unless otherwise stated, the assumptions are as specified in Table 1, which are based on the General Plan 2045 Buildout.

7 2.0 Fundamentals of Noise
This section of the report provides basic information about noise and presents some of the terms used within the report.

2.1 Sound, Noise, and Acoustics
Sound is a disturbance created by a moving or vibrating source and is capable of being detected by the hearing organs. Sound may be thought of as mechanical energy of a moving object transmitted by pressure waves through a medium to a human ear. For traffic or stationary noise, the medium of concern is air. Noise is defined as sound that is loud, unpleasant, unexpected, or unwanted.

2.2 Frequency and Hertz
A continuous sound is described by its frequency (pitch) and its amplitude (loudness). Frequency relates to the number of pressure oscillations per second. Low-frequency sounds are low in pitch (bass sounding) and high-frequency sounds are high in pitch (squeak). These oscillations per second (cycles) are commonly referred to as Hertz (Hz). The human ear can hear from the bass pitch starting at 20 Hz to the high pitch of 20,000 Hz.

2.3 Sound Pressure Levels and Decibels
The amplitude of a sound determines its loudness. The loudness of sound increases or decreases as the amplitude increases or decreases. Sound pressure amplitude is measured in units of micro-Newton per square meter (µN/m2), also called micro-Pascal (µPa). One µPa is approximately one hundred billionths (0.00000000001) of normal atmospheric pressure. Sound pressure level (SPL or Lp) is used to describe in logarithmic units the ratio of actual sound pressures to a reference pressure squared. These units are called decibels abbreviated dB.

2.4 Addition of Decibels
Because decibels are on a logarithmic scale, sound pressure levels cannot be added or subtracted by simple plus or minus addition. When two sounds of equal SPL are combined, they will produce an SPL 3 dB greater than the single SPL. In other words, sound energy that is doubled produces a 3 dB increase.

If two sounds differ by approximately 10 dB, the higher sound level is the predominant sound. When combining sound levels, estimates shown in Table 2 may be utilized.

Table 2: Decibel Addition
When Two Decibel Values Differ by: Add This Amount to Higher Value Example 0 or 1 dB 3 dB 70+69=73 dB
2 or 3 dB 2 dB 74+71=76 dB
4 to 9 dB 1 dB 66+60=67 dB
10 dB or more 0 dB 65+55=65 dB

8 2.5 Human Response to Changes in Noise Levels
In general, the healthy human ear is most sensitive to sounds between 1,000 Hz and 5,000 Hz, and it perceives a sound within that range as being more intense than a sound with a higher or lower frequency with the same magnitude. For purposes of this report as well as with most environmental documents, A-scale weighting is typically used and is reported in terms of the A-weighted decibel (dBA). The A-scale was designed to account for the frequency-dependent sensitivity of the human ear. Typical A-weighted noise levels are shown in Table 3.

In general, the human ear can barely perceive a change in the noise level of 3 dB. As shown in Table 4, a change in 5 dB is readily perceptible, and a change in 10 dB is perceived as being twice or half as loud.

As previously discussed, a doubling of sound energy results in a 3 dB increase in sound, which means that a doubling of sound energy (e.g., doubling the volume of traffic on a highway) would result in a barely perceptible change in sound level.

2.6 Noise Descriptors
Noise in our daily environment fluctuates over time. Some noise levels occur in regular patterns, and others are random. Some noise levels are constant, while others are sporadic. Noise descriptors were created to describe the different time-varying noise levels.

A-Weighted Sound Level: The sound pressure level in decibels as measured on a sound level meter using the A-weighted filter network. The A-weighting filter de-emphasizes the very low and very highfrequency components of the sound in a manner similar to the response of the human ear. A numerical method of rating human judgment of loudness.

Ambient Noise Level: The composite of noise from all sources, near and far. In this context, the ambient noise level constitutes the normal or existing level of environmental noise at a given location.

Community Noise Equivalent Level (CNEL): The average equivalent A-weighted sound level during a 24- hour day, obtained after the addition of five (5) decibels to sound levels in the evening from 7:00 to 10:00 PM and after the addition of ten (10) decibels to sound levels in the night between 10:00 PM and 7:00 AM.

Decibel (dB): A unit for measuring the amplitude of a sound, equal to 20 times the logarithm to the base 10 of the ratio of the pressure of the sound measured to the reference pressure, which is 20 micropascals. dBA: A-weighted sound level (see definition above).

Equivalent Sound Level (LEQ): The sound level corresponding to a steady noise level over a given sample period with the same amount of acoustic energy as the actual time-varying noise level. The energy average noise level during the sample period.

Habitable Room: Any room meeting the requirements of the California Building Code or other applicable regulations which is intended to be used for sleeping, living, cooking, or dining purposes, excluding such enclosed spaces as closets, pantries, bath or toilet rooms, service rooms, connecting corridors, laundries, unfinished attics, foyers, storage spaces, cellars, utility rooms, and similar spaces.

General Plan Update
Noise Impact Study
City of Lawndale, CA Fundamentals of Noise
10 L(n): The A-weighted sound level exceeded during a certain percentage of the sample time. For example, L10 in the sound level exceeded 10 percent of the sample time. Similarly, L50, L90, L99, etc.

Noise: Any unwanted sound or sound which is undesirable because it interferes with speech and hearing, is intense enough to damage hearing, or is otherwise annoying. The State Noise Control Act defines noise as “...excessive undesirable sound...”.

Outdoor Living Area: Outdoor spaces that are associated with residential land uses typically used for passive recreational activities or other noise-sensitive uses. Such spaces include patio areas, barbecue areas, jacuzzi areas, etc. associated with residential uses; outdoor patient recovery or resting areas associated with hospitals, convalescent hospitals, or rest homes; outdoor areas associated with places of worship which have a significant role in services or other noise-sensitive activities; and outdoor school facilities routinely used for educational purposes which may be adversely impacted by noise. Outdoor areas usually not included in this definition are: front yard areas, driveways, greenbelts, maintenance areas and storage areas associated with residential land uses; exterior areas at hospitals that are not used for patient activities; outdoor areas associated with places of worship and principally used for shortterm social gatherings; and, outdoor areas associated with school facilities that are not typically associated with educational uses prone to adverse noise impacts (for example, school play yard areas).

Percent Noise Levels: See L(n).

Sound Level (Noise Level): The weighted sound pressure level obtained by use of a sound level meter having a standard frequency filter for attenuating part of the sound spectrum.

Sound Level Meter: An instrument, including a microphone, an amplifier, an output meter, and frequency weighting networks for the measurement and determination of noise and sound levels.

Single Event Noise Exposure Level (SENEL): The dBA level which, if it lasted for one second, would produce the same A-weighted sound energy as the actual event.

2.7 Tonal Sounds
A pure tone sound is a sound produced at or near a single frequency. Laboratory tests have shown that humans are more perceptible to changes in sound levels of a pure tone. For a noise source to contain a “pure tone,” there must be a significantly higher A-weighted sound energy in a given frequency band than in the neighboring bands, thereby causing the noise source to “stand out” against other noise sources. A pure tone occurs if the sound pressure level in the one-third octave band with the tone exceeds the average of the sound pressure levels of the two contagious one-third octave bands by 5 dB for center frequencies of 500 Hertz (Hz) and above; by 8 dB for center frequencies between 160 and 400 Hz; and by 15 dB for center frequencies of 125 Hz or less.

2.8 Sound Propagation
As sound propagates from a source it spreads geometrically. Sound from a small, localized source (i.e., a point source) radiates uniformly outward as it travels away from the source in a spherical pattern. The General Plan Update
Noise Impact Study
City of Lawndale, CA Fundamentals of Noise
11 sound level attenuates at a rate of 6 dB per doubling of distance. The movement of vehicles down a roadway makes the source of the sound appear to propagate from a line (i.e., line source) rather than a point source. This line source results in the noise propagating from a roadway in a cylindrical spreading versus a spherical spreading that results from a point source. The sound level attenuates for a line source at a rate of 3 dB per doubling of distance.

Research has demonstrated that atmospheric conditions can have a significant effect on noise levels when noise receivers are located 200 feet or more from a noise source. Wind, temperature, air humidity, and turbulence can further impact have far sound can travel.

2.9 Ground Absorption
As noise propagates from the source, it is affected by the ground and atmosphere. Noise models use hard site (reflective surfaces) and soft site (absorptive surfaces) to help calculate predicted noise levels.

Hard site conditions assume no excessive ground absorption between the noise source and the receiver.

Soft site conditions such as grass, soft dirt, or landscaping attenuate noise at a rate of 1.5 dB per doubling of distance. When added to the geometric spreading, the excess ground attenuation results in an overall noise attenuation of 4.5 dB per doubling of distance for a line source and 7.5 dB per doubling of distance for a point source.

2.10 Sound Attenuation
Noise-related land use issues are typically composed of three basic elements: (1) the noise source, (2) a transmission path, and (3) a receiver.

The appropriate acoustical treatment for a given project should consider the nature of the noise source and the sensitivity of the receiver. When the potential for a noise-related problem is present, either avoidance of the noise-related problem or noise control techniques should be selected to provide an acceptable noise environment for the receiver while remaining consistent with local aesthetic standards and practical structural and economic limits. Fundamental noise control options are described below.

2.10.1 Noise Barriers
Effective noise barriers can reduce noise levels by 10 to 15 dBA, cutting the loudness of traffic noise in half. To achieve that reduction, the barrier must be high enough and long enough to block the line-ofsight of the vehicles on the road. A noise barrier can still achieve a 5 dBA noise level reduction when it is tall enough to barely allow a line-of-sight of the vehicles. A noise barrier is most effective when placed close to the noise source or receiver. When the noise barrier is an earthen berm instead of a wall, the noise attenuation can be increased by another 3 dBA.

2.10.2 Setbacks
Noise exposure may be reduced by increasing the setback distance between the noise source and the receiving use. Setback areas can take the form of open space, frontage roads, recreational areas, and storage yards. The available noise attenuation from this technique is limited by the characteristics of the noise source but generally ranges between 4 and 6 dBA.

General Plan Update
Noise Impact Study
City of Lawndale, CA Fundamentals of Noise
12 2.10.3 Site Design
Buildings can be placed on a property to shield other structures or areas affected by noise and to prevent an increase in noise levels caused by reflections. The use of one building to shield another can significantly reduce overall noise control costs, particularly if the shielding structure is insensitive to noise. An example would be placing a detached garage nearest the noise source to shield the house or backyard. Site design should guard against creating reflecting surfaces that may increase onsite noise levels. For example, two buildings placed at an angle facing a noise source may cause noise levels within that angle to increase by up to 3 dBA. The open end of U-shaped buildings should point away from noise sources for the same reason. Landscaping walls or noise barriers located within a development may inadvertently reflect noise to a noise-sensitive area unless carefully located.

2.10.4 Building Facades
When interior noise levels are of concern in a noisy environment, noise reduction may be obtained through the acoustical design of building facades. Standard construction practices provide a noise reduction of 10–15 dBA for building facades with open windows and a noise reduction of approximately 25 dBA when windows are closed (Table 5). An exterior-to-interior noise reduction of 25 dBA can be obtained by requiring that building design include adequate ventilation systems, which would allow windows facing a noise source to remain closed, even during periods of excessively warm weather.

Where greater noise reduction is required, acoustical treatment of the building facade may be necessary.

Reducing relative window area is the most effective control technique, followed by providing acoustical glazing (e.g., thicker glass or increased air space between panes) within frames with low air infiltration rates, using fixed (i.e., non-movable) acoustical glazing, or eliminating windows. Noise transmitted through walls can be reduced by increasing wall mass (e.g., using stucco or brick in lieu of wood siding), or isolating wall members by using double or staggered stud walls, while noise transmitted through doorways can be lessened by reducing door area, using solid-core doors, or sealing door perimeters with suitable gaskets. Noise-reducing roof treatments include using plywood sheathing under roofing materials.

13 2.10.5 Landscaping
While the use of trees and other vegetation is often thought to provide significant noise attenuation, approximately 100 feet of dense foliage – with no visual path extending through the foliage – is required to achieve a 5 dBA attenuation of traffic noise. Thus, the use of vegetation as a noise barrier is not considered a practical method of noise control unless large tracts of dense foliage are part of the existing landscape.

Vegetation can be used, however, to acoustically “soften” intervening ground between a noise source and a receiver, increasing ground absorption of sound, and thus, increasing the attenuation of sound with distance. Planting trees and shrubs also offers aesthetic and psychological value, and it may reduce adverse public reaction to a noise source by removing the source from view, even though noise levels would be largely unaffected.

3.1 Vibration Descriptors
Ground-borne vibrations consist of rapidly fluctuating motions within the ground that have an average motion of zero. The effects of ground-borne vibrations typically only cause a nuisance to people, but at extreme vibration levels, damage to buildings may occur. Although ground-borne vibration can be felt outdoors, it is typically only an annoyance to people indoors, where the associated effects of the shaking of a building can be notable. Ground-borne noise is an effect of ground-borne vibration and mainly exists indoors since it is produced from noise radiated from the motion of the walls and floors of a room and may also consist of the rattling of windows or dishes on shelves. Several different methods are used to quantify vibration amplitude. Typical human reaction and effect on buildings due to ground-borne vibration is shown in Table 6. Exhibit E illustrates common vibration sources and the human and structural responses to ground-borne vibration.

PPV – Known as the peak particle velocity (PPV) which is the maximum instantaneous peak in vibration velocity, typically given in inches per second.

RMS – Known as root mean squared (RMS) can be used to denote vibration amplitude VdB – A commonly used abbreviation to describe the vibration level (VdB) for a vibration source.

Typically, developed areas are continuously affected by vibration velocities of 50 VdB or lower. These continuous vibrations are not noticeable to humans whose threshold of perception is around 65 VdB.

Outdoor sources that may produce perceptible vibrations are usually caused by construction equipment, steel-wheeled trains, and traffic on rough roads, while smooth roads rarely produce perceptible groundborne noise or vibration.

The California Department of Transportation has published one of the seminal works for the analysis of ground-borne noise and vibration relating to transportation- and construction-induced vibrations and although the Project is not subject to these regulations, it serves as useful tools to evaluate vibration impacts. (California Department of Transportation, 2020).

3.3 Vibration Propagation
There are three main types of vibration propagation: surface, compression, and shear waves. Surface waves, or Rayleigh waves, travel along the ground’s surface. These waves carry most of their energy along an expanding circular wave front, similar to ripples produced by throwing a rock into a pool of water. P-waves, or compression waves, are body waves that carry their energy along an expanding spherical wave front. The particle motion in these waves is longitudinal (i.e., in a “push-pull” fashion). Pwaves are analogous to airborne sound waves. S-waves, or shear waves, are also body waves that carry energy along an expanding spherical wave front. However, unlike P-waves, the particle motion is transverse, or side-to-side and perpendicular to the direction of propagation. As vibration waves propagate from a source, the vibration energy decreases in a logarithmic nature and the vibration levels typically decrease by 6 VdB per doubling of the distance from the vibration source. This drop-off rate can vary greatly depending on the soil but has been shown to be effective enough for screening purposes, in order to identify potential vibration impacts that may need to be studied through actual field tests.

17 4.0 Regulatory Setting
The proposed Project is located in the City of Lawndale, and noise regulations are addressed through the efforts of various federal, state, and local government agencies. The agencies responsible for regulating noise are discussed below.

4.1 Federal Regulations

4.1.1 Noise Control Act of 1972
The Federal Office of Noise Abatement and Control (ONAC) was originally tasked with implementing the Noise Control Act. However, it was eventually eliminated leaving other federal agencies and committees to develop noise policies and programs. Some examples of these agencies are as follows:
• The Department of Transportation (DOT) assumed a significant role in noise control through its various agencies.
• The Federal Aviation Agency (FAA) regulates noise from aircraft and airports. • The Federal Highway Administration (FHWA) regulates noise from the interstate highway system.
• The Occupational Safety and Health Administration (OSHA) is responsible for the prohibition of excessive noise exposure to workers.

The federal government advocates that local jurisdictions use their land use regulatory authority to arrange new development in such a way that “noise sensitive” uses are either prohibited from being constructed adjacent to a highway or that the developments are planned and constructed in such a manner that potential noise impacts are minimized.

Since the federal government has preempted the setting of standards for noise levels that can be emitted by the transportation source, the City is restricted to regulating the noise generated by the transportation system through nuisance abatement Codes and land use planning.

The intent of a General Plan Noise Element or Section is to set goals to limit and reduce the effects of noise intrusion and to set acceptable noise levels for varying types of land uses. To this end, the City has the authority to set land use noise standards and restrict private activities that generate excessive or intrusive noise. However, it should be recognized that the City does not have the authority to regulate all sources of noise within the City and various other agencies may supersede City authority. The following is a summary of some federal agency requirements that apply to noise within the Project Area.

4.1.2 Federal Highway Administration
Federal Highway Administration State routes and freeways that run through the City are subject to Federal funding and, as such, are under the purview of the Federal Highway Administration (FHWA). The FHWA has developed noise standards that are typically used for Federally funded roadway projects or projects that require either Federal or Caltrans review. These noise standards are based on Leq and L10 values and are included in Table 7, FHWA Design Noise Levels.

Notes: Either Leq or L10 (but not both) design noise levels may be used on a project.

U.S. Department of Housing and Urban Development
The Department of Housing and Urban Development (HUD) issues formal requirements related specifically to standards for exterior noise levels along with policies for approving HUD-supported or assisted housing projects in high noise areas. In general, these requirements established three zones.

These include:
• 65 dBA Ldn or less - an acceptable zone where all projects could be approved, • Exceeding 65 dBA Ldn but not exceeding 75 dBA Ldn - a normally unacceptable zone where mitigation measures would be required, and each Project would have to be individually evaluated for approval or denial. These measures must provide 5 dBA of attenuation above the attenuation provided by standard construction required in a 65 to 70 dBA Ldn area and 10 dBA of attenuation in a 70 to 75 dBA Ldn area, and
• Exceeding 75 dBA Ldn - an unacceptable zone in which projects would not, as a rule, be approved.

4.1.3 The Federal Interagency Committee on Noise
The Federal Interagency Committee on Noise (FICON) developed guidance for the assessment of projectgenerated increases in noise levels that consider the ambient noise level. The FICON recommendations are based on studies of the percentage of persons highly annoyed by aircraft noise. These recommendations are often used for different types of environmental noise such as traffic noise. A readily perceptible 5 dBA or greater project-related noise level increase is considered a significant impact General Plan Update
Noise Impact Study
City of Lawndale, CA Regulatory Setting
19 when the noise criteria for a given land use is exceeded. In areas where the existing noise levels range from 60 to 65 dBA Ldn, a 3 dBA barely perceptible noise level increase is considered significant. When the existing noise levels already exceed 65 dBA Ldn, any increase in community noise louder than 1.5 dBA or greater is considered a significant impact since it likely contributes to an existing noise exposure exceedance.

4.2 State Regulations

4.2.1 California Department of Health Services
The California Department of Health Services (DHS) Office of Noise Control studied the correlation between noise levels and their effects on various land uses. As a result, the DHS established four categories for judging the severity of noise intrusion on specified land uses. These categories are presented in the State Land Use Compatibility for Community Noise Exposure table (California Office of Noise Control, 2017).

4.2.2 The California Building Code
Section 1206.4 of the 2022 California Building Code (Cal. Code Regs., Title 24, Part 2), Chapter 12 (Interior Environment), establishes an interior noise criterion of 45 dBA CNEL in any habitable room. Per California Building Code, Chapter 2 (Definitions), a habitable space is A space in a building for living, sleeping, eating or cooking. Bathrooms, toilet rooms, closets, halls, storage or utility spaces and similar areas are not considered habitable spaces. This section applies to dwelling and sleeping units.

4.2.3 California Green Building Standards Code
California Green Building Standards Code (2022), Chapter 5 (Non-residential Mandatory Measures) Section 5.507.4 (Acoustical Control), applies to all proposed buildings that people may occupy but are not residential dwelling units, with the exception of factories, stadiums, storage, enclosed parking structures, and utility buildings.

Buildings must comply with Section 5.507.4.1 or Section 5.507.4.2. Section 5.507.4.1 requires wall and roof-ceiling assemblies exposed to the noise source making up the building, or addition envelope or altered envelope, shall meet a composite Sound Transmission Class (STC) rating of at least 50 or a composite Outdoor to Indoor Transmission Class (OITC) rating of no less than 40, with exterior windows of a minimum STC of 40 or OITC of 30 when within the 65 CNEL noise contour of an airport, freeway, expressway, railroad, industrial source, or fixed-guideway source. If contours are not available, buildings exposed to 65 dB Leq(h) must meet a composite STC rating of at least 45 or OITC of 35 with exterior windows of at least STC 40 or OITC 30. Section 5.507.4.2 requires that the interior noise attributable to exterior sources must not exceed 50 dBA Leq(h) during any hour of operation. Section 5.507.4.3 requires that assemblies separating tenant spaces from tenant spaces or public places must have an STC of at least 40.

Existing planning policies and noise regulations applicable to noise within the City of Lawndale are presented in the Noise Plan of the City of Lawndale General Plan 1992 and within the City of Lawndale Municipal Code. Applicable goals, policies, and regulations are presented below.

4.3.1 City of Lawndale General Plan 1992
General Plan Goals, Policies and Actions
The 1992 General Plan Noise Plan includes the following goals, policies and implementation programs that are intended to avoid or reduce noise impacts related to transportation, stationary, and construction related noise sources.

Noise Goal 1: To achieve and maintain an environment which is free from excessive or harmful noise through identification, control and abatement.

Policies
Policy 1a: Control and abate undesirable sounds through the development of land use compatibility guidelines and a noise ordinance.

Policy 1b: Encourage the development of industrial and commercial land uses which do not produce excessive noise.

Policy 1c: Discourage development of noise sensitive land uses in area impacted by high noise levels.

Policy 1d: Ensure that sensitive land uses are not subjected to inappropriate noise levels resulting from transportation systems.

Policy 1e: Maintain coordination of noise control policies and standards with the surrounding cities and Caltrans.

Policy 1f: Provide for implementation, periodic review and revision of the Noise Element.

Policy 1g: Provide for the education of the community in the nature and extent of noise in the City of Lawndale.

Implementation Programs

1.1 Comprehensive Noise Ordinance Adoption: Adopt a comprehensive noise ordinance to prohibit unwanted and unnecessary sound. The ordinance shall identify acceptable property line sound level limits and control noise sources such as barking dogs, mechanical equipment, amplified music, construction activity and other noise identified as disturbing, excessive or offensive.

1.2 Noise Compatibility Standards: Adopt the land use noise compatibility standards presented in Figure A for general planning and zoning purposes.

1.3 Noise Insulation Standards: Enforce the California Administrative Code, Title 24, Noise Insulation Standards. Title 24 requires that an acoustical analysis be performed for all new multi-family construction in areas where the exterior sound level exceeds 60 CNEL. The analysis shall ensure that the building design limits the interior noise environment to 45 CNEL or below.

City of Lawndale, CA Regulatory Setting
21 1.4 Noise Insulation Standards for Single-Family Dwellings: Adopt a policy or implementation ordinance making California Administrative Code, Title 24, Noise Insulation Standards applicable to new single0family dwellings.

1.5 Project Review: Review actions or projects that may have the potential to generate noise impacts which may impact existing land uses.

1.6 Acoustical Analysis: Require noise studies for projects where exterior noise levels exceed 60 dB CNEL to identify potential noise impacts, analyze mitigation alternatives, and identify methods to monitor the effectiveness of the mitigation following implementation.

1.7 Transportation Noise Standards: Develop noise standards for use in reviewing the construction and improvement of any roadway, railroad, or other transit system.

1.8 Enforce Motor Vehicle Code: Enforce the provisions of the State Motor Vehicle Code which requires that all vehicles be equipped with a properly maintained muffler and that the exhaust system not be modified.

1.9 Regulate Traffic Flow: Review traffic flow systems and synchronize signals to avoid traffic stops which produce excessive noise wherever possible.

1.10 Limit Truck Noise: Limit truck traffic in noise sensitive areas.  Increasing the distance from the noise source to sensitive receptors by creation of setbacks;
 Placing non-noise sensitive uses such as parking lots and utility areas between the noise source and receiver; and
 Orient usable outdoor living space such as balconies, patios, and children play areas away from roadways.

Noise/Land Use Compatibility
Exhibit F, Noise and Land Use Compatibility presents a land use compatibility chart for community noise originally prepared by the California Office of Noise Control (1987). The table identifies “normally acceptable,” “conditionally acceptable,” “normally unacceptable,” and “clearly unacceptable” exterior noise levels for various land uses. A “conditionally acceptable” designation implies new construction or development should be undertaken only after a detailed analysis of the noise reduction requirements for each land use is made and needed noise insulation features are incorporated in the design. By comparison, a “normally acceptable” designation indicates that standard construction can occur with no special noise reduction requirements. This land use compatibility chart is based on the 24-hour descriptor CNEL.

The following Goal, Policies, and Actions are proposed for the 2023 City of Lawndale General Plan.

Goal PS-6: An environment where excessive or harmful noise pollution is limited.

Noise levels within the community can affect the quality of life experienced by people living and working in Lawndale. High noise levels can create stress and irritation. The following policies and actions address other potential sources of excessive noise by creating effective strategies to reduce and limit the community’s exposure to loud sources of noise.

PS-6 Policies
PS-6.1 California Building Code. Adhere to the latest standards related to noise in the most current edition of the California Building Code to avoid or minimize noise pollution in the community.

PS-6.2 Noise Exposure. Consider the noise compatibility of existing and future development when making land use planning decisions. Require development and infrastructure projects to be consistent with the land use compatibility standards contained in Table PS-1 and the Lawndale Municipal Code to facilitate acceptable noise exposure levels for existing and future development.

PS-6.3 Noise Mitigation. Require new development to mitigate excessive noise to the standards indicated in Table PS-1 and the Lawndale Municipal Code through best practices, including building location and orientation, building design features, placement of noise-generating equipment away from sensitive receptors, shielding of noise-generating equipment, placement of noise-tolerant features between noise sources and sensitive receptors, and use of noiseminimizing materials.

PS-6.4 Acoustical Studies. Require acoustical studies for new discretionary developments and transportation improvements that have the potential to affect existing noise-sensitive uses such as schools, hospitals, libraries, care facilities, and residential areas; and for projects that would introduce new noise-sensitive uses into an area where existing noise levels may exceed the thresholds identified in this element. For projects that are required to prepare an acoustical study, the following mobile and stationary noise source criteria shall be used to determine the significance of those impacts.

A. Mobile Noise Sources:
● Where existing traffic noise levels are within or below the “normally acceptable” noise criteria at the affected land use (see Table PS-1), a readily perceptible 5 dBA CNEL or greater increase in roadway noise will be considered significant; ● Where existing traffic noise levels falls within the “conditionally acceptable” noise criteria at the sensitive land use, a +3 dBA CNEL or greater increase in roadway noise levels will be considered significant; and

Noise Impact Study
City of Lawndale, CA Regulatory Setting
24 ● Where existing traffic noise levels exceed the “conditionally acceptable” noise criteria at the sensitive land use, a + 1.5 dBA CNEL or greater increase in roadway noise levels will be considered significant
B. Stationary and Non-Transportation Noise Sources
A significant impact will occur if the project results in an exceedance of the noise level standards contained in this element, or the project will result in an increase in ambient noise levels by more than 3 dB, whichever is greater.

PS-6.5 Roadway Noise. Encourage nonmotorized transportation alternatives for local trips and the implementation of noise sensitivity measures in the public realm, including traffic-calming road design, lateral separation, natural buffers, and setbacks to decrease excessive motor vehicle noise.

PS-6.6 Freeway Noise. Coordinate with the California Department of Transportation (Caltrans) to achieve maximum noise abatement in the design of new freeway projects or improvements along I-405.

PS-6.7 Railroad Noise. Coordinate with Burlington Northern and Santa Fe Rail (BNSF) to support and maintain reasonable limits on the use of bells and whistles, and the speed and hours of rail operation in affected areas of the City, and maintain adequate setbacks and buffer zones along rail lines to reduce adverse noise impacts on sensitive receptors.

PS-6.8 Commercial Noise. Require the use of noise attenuation measures, including screening and buffering techniques, for all new commercial development expected to produce excessive noise; in existing cases where the City’s noise standards are exceeded, work with Code Enforcement to require compliance.

PS-6.9 Construction Noise. Require construction activities to reduce noise impacts on adjacent uses to the criteria identified to the maximum extent feasible by complying with Chapter 8.20 of the Lawndale Municipal Code and use best practices.

PS-6.10 Special Events. Temporary special events which generate noise in excess of local noise standards including, but not limited to, festivals, concerts, parades, and other similar activities may be considered on a case-by-case basis through issuance of a temporary use permit.

PS-6.11 Temporary Emergency Operations and Emergency Equipment Usage. Temporary emergency operations or emergency equipment usage are exempt from noise standard criteria set by this element.

PS-6.12 Interjurisdictional and Multiagency Coordination. Coordinate with neighboring cities and transportation providers such as Caltrans to minimize noise conflicts between land uses along the City's boundaries.

PS-6.13 Community Education. Provide education to the community regarding potential noise sources and how to reduce them or report violations.
