Appendix A5.1 Initial Study Appendices — Riverside City Council, July 5, 2022 (part 2 of 7)

City or would commute in from neighboring jurisdictions, this analysis conservatively assumes all 746 future employees would move into the City for employment.

Based on an average household size of 3.283, the project would result in an indirect population increase of approximately 2,446 persons.

SCAG growth forecasts in the 2016-2040 RTP/SCS estimate the City’s population to reach 386,600 persons by 2040, representing a total increase of 75,900 persons between 2012 and 2040.4 The
project’s potential indirect population growth (2,446 persons) represents 3.22 percent of the City’s anticipated population increase by 2040, and only 0.63 percent of the City’s total projected 2040 population.

Additionally, SCAG growth forecasts in the 2016-2040 RTP/SCS estimate the City’s employment to reach 200,500 jobs by 2040, representing a total increase of 80,500 jobs between 2012 and 2040.5 The approximately 746 project-generated jobs represent 0.93 percent of the City’s anticipated jobs increase by 2040, and only 0.37 percent of the City’s total projected 2040 employment.

Therefore, the project would not cause the General Plan buildout population or employment forecasts to be exceeded. The population, housing, and employment forecasts, which are adopted by SCAG’s Regional Council, are based on the local plans and policies applicable to the City. Additionally, as the SCAQMD has incorporated these same projections into the 2016 AQMP, it can be concluded that the proposed project would be consistent with the projections. b) Would the project implement all feasible air quality mitigation measures? The proposed project would result in less than significant air quality impacts. Compliance with all feasible emission reduction rules and measures identified by the SCAQMD would be required as identified in Impact Statements AQ-2 and AQ-3. As such, the proposed project meets this 2016 AQMP consistency criterion.
c) Would the project be consistent with the land use planning strategies set forth in the AQMP? Land use planning strategies set forth in the 2016 AQMP are primarily based on the 2016-2040 RTP/SCS. The project is an expansion of the existing Kaiser Permanente Riverside Medical Center to address the need for a bed tower to convert existing double occupancy beds to single occupancy; increase capacity in neonatal intensive care unit beds, operating rooms, and interventional radiology; and resolve critical functional deficiencies in key clinical services, including the emergency department and other services. The Kaiser Permanente Riverside Medical Center is a major employment center within the City and is sited near the La Sierra Metrolink Station and local Riverside Transit lines. The project would generate approximately 746 jobs in a jobs-rich area of the City near commercial, residential, office, medical, and business park uses, thus enhancing the La Sierra District as a transit-oriented, mixed-use employment center.

As such, the project would be consistent with the actions and strategies of the 2016-2040 RTP/SCS. Furthermore, project consistency with the 2016-2040 RTP/SCS and the 2016 AQMP would promote the City’s goal to protect air quality by incorporating General Plan Air Quality 3 Ibid. 4 Southern California Association of Governments, 2016-2040 Regional Transportation Plan/Sustainable Communities Strategy Demographics & Growth Forecast Appendix, dated April 2016. 5 Ibid.

Element objectives and policies. As such, the proposed project would meet this AQMP consistency criterion.

In conclusion, the determination of 2016 AQMP consistency is primarily concerned with the long-term influence of a project on air quality in the Basin. The proposed project would not result in a long-term impact on the region’s ability to meet State and Federal air quality standards. Also, the proposed project would be consistent with the goals and policies of the 2016 AQMP for control of fugitive dust; refer to Impact Statement AQ-2. As discussed above, the proposed project’s long-term influence would also be consistent with the SCAQMD and SCAG’s goals and policies and is, therefore, considered consistent with the 2016 AQMP.

Mitigation Measures: No mitigation is required.

Impact AQ-2: Would the project result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable Federal or State ambient air quality standard?
Less Than Significant Impact.

Short-Term Construction
The project involves construction activities associated with demolition, grading, building construction, paving, and architectural coating applications. Construction of the project is anticipated to occur over an approximate 58-month timeframe from the onset of demolition through final construction. Demolition and construction would be completed in seven phases. Phase 1-4 would be completed in approximately 18 months and Phase 5-7 would be completed in approximately 40 months.

Demolition and construction would be accomplished with cranes, dozers, and other heavy equipment.

Waste materials would be uploaded onto large trucks using small cranes, forklifts, and other construction equipment as needed. Demolition equipment would be delivered to the site on low-bed trucks unless the equipment can be driven to the site (e.g., on boom trucks). Refer to Appendix A, Air Quality Emissions Data, for a detailed equipment list. The proposed construction schedule is shown in Table 7, Construction Schedule; and the proposed equipment list is shown in Table 8, Construction Equipment List.

Notes:

1. Emissions were calculated using CalEEMod version 2020.4.0, as recommended by the SCAQMD. Winter emissions represent worst-case scenario and is therefore presented as a conservative analysis.

2. The reduction/credits for construction emissions are based on adjustments to CalEEMod and are required by the SCAQMD Rules. The adjustments applied in CalEEMod includes the following: properly maintain mobile and other construction equipment; replace ground cover in disturbed areas quickly; water exposed surfaces three times daily; cover stockpiles with tarps; and limit speeds on unpaved roads to 15 miles per hour.

3. Construction thresholds apply to both the South Coast Air Basin and Coachella Valley (Salton Sea and Mojave Desert Air Basins). Source: South Coast AQMD, CEQA Handbook, 1993.

Fugitive Dust Emissions
Construction activities are a source of fugitive dust emissions that may have a substantial, temporary impact on local air quality. In addition, fugitive dust may be a nuisance to those living and working in the project area. Fugitive dust emissions are associated with land clearing, ground excavation, cut-and-fill, and truck travel on unpaved roadways. Fugitive dust emissions vary substantially from day to day, depending on the level of activity, specific operations, and weather conditions. Fugitive dust from site preparation, grading, and construction is expected to be short-term and would cease upon project completion. It should be noted that most of this material is inert silicates, rather than the complex organic particulates released from combustion sources, which are more harmful to health.

Dust (larger than 10 microns) generated by such activities usually becomes more of a local nuisance than a serious health problem. Of particular health concern is the amount of PM10 generated as a part of fugitive dust emissions. PM10 poses a serious health hazard alone or in combination with other pollutants.

PM2.5 is mostly produced by mechanical processes. These include automobile tire wear, industrial processes such as cutting and grinding, and re-suspension of particles from the ground or road surfaces by wind and human activities such as construction or agriculture. PM2.5 is mostly derived from combustion sources, such as automobiles, trucks, and other vehicle exhaust, as well as from stationary sources. These particles are either directly emitted or are formed in the atmosphere from the combustion of gases such as NOX and SOX combining with ammonia. PM2.5 components from material in the earth’s crust, such as dust, are also present, with the amount varying in different locations.

Construction activities would comply with SCAQMD Rule 402, which requires implementation of dust suppression techniques to prevent fugitive dust from creating a nuisance off-site, and Rule 403, which requires that excessive fugitive dust emissions be controlled by regular watering or other dust prevention measures. Adherence to SCAQMD Rule 403 would greatly reduce PM10 and PM2.5 concentrations. It should be noted that these estimated reductions were applied in CalEEMod.

Kaiser Permanente Riverside Medical Center Expansion Project Air Quality Technical Memorandum

Page 23 ends

As depicted in Table 9, total PM10 and PM2.5 emissions would not exceed the SCAQMD thresholds during construction. Therefore, particulate matter impacts during construction would be less than significant.

Construction Equipment and Worker Vehicle Exhaust
Exhaust emissions from construction activities include emissions associated with the transport of machinery and supplies to and from the project site, emissions produced on-site as the equipment is used, and emissions from trucks transporting materials to and from the site. Standard SCAQMD regulations, such as maintaining all construction equipment in proper tune and shutting down equipment when not in use for extended periods of time, would be implemented. Construction equipment and worker vehicle exhaust emissions have been accounted for within the daily short-term construction emissions (refer to Table5) and would be below the established SCAQMD thresholds. Therefore, air quality impacts from equipment and vehicle exhaust emission would be less than significant.

ROG Emissions
In addition to gaseous and particulate emissions, the application of asphalt and surface coatings creates ROG emissions, which are O3 precursors. In accordance with the methodology prescribed by the SCAQMD, the ROG emissions associated with paving and architectural coating have been quantified with the CalEEMod model. As required by SCAQMD Regulation XI, Rule 1113 – Architectural Coating, all architectural coatings for the proposed structures would comply with specifications on painting practices as well as regulation on the ROG (also refer to as VOC) content of paint. ROG emissions associated with the proposed project would be less than significant; refer to Table 9.

Total Daily Construction Emissions
In accordance with the SCAQMD Guidelines, CalEEMod was utilized to model construction emissions for ROG, NOX, CO, SOX, PM10, and PM2.5. As indicated in Table 9, criteria pollutant emissions during construction of the proposed project would not exceed the SCAQMD significance thresholds. Thus, total construction related air emissions impacts would be less than significant.

Naturally Occurring Asbestos
Asbestos is a term used for several types of naturally occurring fibrous minerals that are a human health hazard when airborne. The most common type of asbestos is chrysotile, but other types such as tremolite and actinolite are also found in California. Asbestos is classified as a known human carcinogen by State, Federal, and international agencies and was identified as a toxic air contaminant by CARB in 1986.

Asbestos can be released from serpentinite and ultramafic rocks when the rock is broken or crushed. At the point of release, the asbestos fibers may become airborne, causing air quality and human health hazards. These rocks have been commonly used for unpaved gravel roads, landscaping, fill projects, and other improvement projects in some localities. Asbestos may be released to the atmosphere due to vehicular traffic on unpaved roads, during grading for development projects, and at quarry operations. All of these activities may have the effect of releasing potentially harmful asbestos into the air. Natural weathering and erosion processes can act on asbestos bearing rock and make it easier for asbestos fibers to become airborne if such rock is disturbed.

Kaiser Permanente Riverside Medical Center Expansion Project Air Quality Technical Memorandum

Page 24 ends

According to the Department of Conservation Division of Mines and Geology, A General Location Guide for Ultramafic Rocks in California – Areas More Likely to Contain Naturally Occurring Asbestos Report6 ,
serpentinite and ultramafic rocks are not known to occur within the project area. Thus, there would be no impact in this regard.

Lead-based Paint
Lead-based paint (LBP) is recognized as a potential health risk because of its known toxics that affect the central nervous system, kidneys, and bloodstream. Lead-based paints were used in residential and commercial buildings until it was banned in 1978. Structures built in the U.S. before 1978 are likely to have some lead-based paint. Improper demolition of structures coated with lead-based paint can result in the release of lead containing particles from the project site and pose a potentially significant impact.

The project proposes to construct a hospital building and a parking structure. The project would involve demolition of some existing pavement, but would not involve the demolition of structures, including those built before 1978. Thus, there would be no impact in this regard.

Long-Term (Operational) Emissions
Long-term air quality impacts would consist of mobile source emissions generated from projectrelated traffic, and emissions from stationary area and energy sources. Emissions generated by the proposed project were calculated and are discussed below.

Mobile Source Emissions
Mobile sources are emissions from motor vehicles, including tailpipe and evaporative emissions.

Depending upon the pollutant being discussed, the potential air quality impact may be of either regional or local concern. For example, ROG, NOX, SOX, PM10, and PM2.5 are all pollutants of regional concern (NOX and ROG react with sunlight to form O3 [photochemical smog], and wind currents readily transport SOX, PM10, and PM2.5); however, CO tends to be a localized pollutant, dispersing rapidly at the source.

The project-generated vehicle emissions have been estimated using CalEEMod. Table 10, Long-Term Operational Air Emissions, presents the anticipated mobile source emissions. As shown in Table 10, emissions generated by vehicle traffic associated with the project would not exceed established SCAQMD thresholds. In addition, the project would include electric vehicle charging stations and parking spaces, ride sharing parking spaces, and bicycle parking spaces on-site to encourage alternative modes of transportation and reduce mobile source emissions. As such, impacts from mobile source air emissions would be less than significant.

Area Source Emissions
Area source emissions would be generated due to an increased demand for natural gas, consumer products, area architectural coatings, and landscaping equipment associated with the development of the proposed project; refer to Table 10.

Energy Source Emissions
Operational energy source emissions are generated as a result of electricity and natural gas usage associated with a project; refer to Table 10. The primary use of electricity and natural gas by the project would be for space heating and cooling, water heating, ventilation, lighting, appliances, and electronics.

Total Operational Emissions
As shown in Table 10, total operational emissions for both summer and winter would not exceed established SCAQMD thresholds. Therefore, impacts in this regard would be less than significant.

Air Quality Health Impacts
Adverse health effects induced by criteria pollutant emissions are highly dependent on a multitude of interconnected variables (e.g., cumulative concentrations, local meteorology and atmospheric conditions, and the number and character of exposed individual [e.g., age, gender]). In particular, ozone precursors ROGs and NOx affect air quality on a regional scale. Health effects related to ozone are therefore the product of emissions generated by numerous sources throughout a region. Existing models have limited sensitivity to small changes in criteria pollutant concentrations, and, as such, translating projectgenerated criteria pollutants to specific health effects or additional days of nonattainment would produce meaningless results. In other words, the project’s less than significant increases in regional air pollution from criteria air pollutants would have nominal or negligible impacts on human health.

As noted in the Brief of Amicus Curiae by the SCAQMD for the Sierra Club vs. County of Fresno, dated April 6, 2015, the SCAQMD acknowledged that it would be extremely difficult, if not impossible to quantify health impacts of criteria pollutants for various reasons including modeling limitations as well as where in Kaiser Permanente Riverside Medical Center Expansion Project Air Quality Technical Memorandum

Page 26 ends

the atmosphere air pollutants interact and form. 7 Further, as noted in the Brief of Amicus Curiae by the San Joaquin Valley Air Pollution Control District (SJVAPCD) for the Sierra Club vs. County of Fresno, SJVAPCD has acknowledged that currently available modeling tools are not equipped to provide a meaningful analysis of the correlation between an individual development project’s air emissions and specific human health impacts.8
The SCAQMD acknowledges that health effects quantification from ozone, as an example is correlated with the increases in ambient level of ozone in the air (concentration) that an individual person breathes.

SCAQMD’s Brief of Amicus Curiae states that it would take a large amount of additional emissions to cause a modeled increase in ambient ozone levels over the entire region. The SCAQMD states that based on their own modeling in the SCAQMD’s 2012 Air Quality Management Plan, a reduction of 432 tons (864,000 pounds) per day of NOX and a reduction of 187 tons (374,000 pounds) per day of VOCs would reduce ozone levels at highest monitored site by only nine parts per billion. As such, the SCAQMD concludes that it is not currently possible to accurately quantify ozone-related health impacts caused by NOX or VOC emissions from relatively small projects (defined as projects with regional scope) due to photochemistry and regional model limitations. Since the project would not exceed SCAQMD thresholds for construction and operational air emissions, the project would have a less than significant impact for air quality health impacts as well.

Mitigation Measures: No mitigation is required.

Impact AQ-3: Would the project expose sensitive receptors to substantial pollutant concentrations? Less Than Significant Impact. Localized Significance Thresholds (LSTs) were developed in response to SCAQMD Governing Boards’ Environmental Justice Enhancement Initiative (I-4). The SCAQMD provided the Final Localized Significance Threshold Methodology (dated June 2003 [revised 2008]) for guidance.

The LST methodology assists lead agencies in analyzing localized air quality impacts. The SCAQMD provides the LST lookup tables for one-, two-, and five-acre projects emitting CO, NOX, PM2.5, and/or PM10.

The LST methodology and associated mass rates are not designed to evaluate localized impacts from mobile sources traveling over the roadways. The SCAQMD recommends that any project over five acres should perform air quality dispersion modeling to assess impacts to nearby sensitive receptors. The project is located within Source Receptor Area (SRA) 23, Metropolitan Riverside. LST thresholds are provided for distances to sensitive receptors of 25, 50, 100, 200, and 500 meters. In order to identify impacts to sensitive receptors, the SCAQMD recommends addressing LSTs for construction and operational impacts (stationary sources only).

Sensitive Receptors
Sensitive receptors are defined as facilities or land uses that include members of the population that are particularly sensitive to the effects of air pollutants, such as children, the elderly, and people with illnesses.

Examples of these sensitive receptors are residences, schools, hospitals, and daycare centers. CARB has identified the following groups of individuals as the most likely to be affected by air pollution: the elderly over 65, children under 14, athletes, and persons with cardiovascular and chronic respiratory diseases such as asthma, emphysema, and bronchitis.

The nearest sensitive receptors to the project site are the single- and multi-family residences as well as a nursing home (Arlington Gardens Care Center) located to the north of the project site across Polk Street.

The single-family residences are located approximately 100 feet to the north of the project site across Polk Street, approximately 450 feet from the nearest project construction area.

Non-Residential Receptors
Commercial and industrial uses (i.e., non-residential receptors) are not included in the definition of sensitive receptor because employees and patrons do not typically remain on-site for a full 24 hours and are usually on-site for eight hours or less. However, the LST Methodology states that “LSTs based on shorter averaging periods, such as the NO2 and CO LSTs, could also be applied to receptors such as industrial or commercial facilities since it is reasonable to assume that a worker at these sites could be present for periods of one to eight hours.”9

The closest commercial use is a commercial building located to the west of the project site across Magnolia Avenue, approximately 170 feet from the project’s construction limit.

Construction LST
The SCAQMD’s guidance on applying CalEEMod to LSTs specifies the number of acres a particular piece of equipment would likely disturb per day. Based on default information provided by CalEEMod, the project is anticipated to disturb more than five acres per day during the grading phase. Therefore, the LST thresholds for five acres was utilized for the construction LST analysis. The nearest sensitive receptors is a commercial building located to the west of the project site across Magnolia Avenue, approximately 170 feet (51.8 meters) from the project’s construction limit (the proposed hospital tower). Therefore, LST values for 25 meters were conservatively used.

Table 11, Localized Emissions Significance, shows the localized construction-related emissions for NOX, CO, PM10, and PM2.5 compared to the LSTs for SRA 23. It is noted that the localized emissions presented in Table 11 are less than those in Table 9 because localized emissions include only on-site emissions (e.g., from construction equipment and fugitive dust) and do not include off-site emissions (e.g., from hauling activities). As shown in Table 11, the project’s localized construction emissions would not exceed the LSTs for SRA 23. Therefore, localized significance impacts from project-related construction activities would be less than significant.

Notes:

1. The 2022 Phase 1-4 grading phase emissions would present the worst-case scenario for NOX, CO, PM10, and PM2.5.

2. The reduction/credits for construction emissions applied in CalEEMod are based on the application of dust control techniques as required by SCAQMD Rule 403. The dust control techniques include the following: properly maintain mobile and other construction equipment; replace ground cover in disturbed areas quickly; water exposed surfaces twice daily; cover stockpiles with tarps; and limit speeds on unpaved roads to 15 miles per hour.

3. The Localized Significance Threshold was determined using Appendix C of the SCAQMD Final Localized Significant Threshold Methodology guidance document for pollutants NOX, CO, PM10, and PM2.5. The Localized Significance Threshold was based on the anticipated daily acreage disturbance for construction (more than five acres; therefore the 5-acre threshold was used) and Source Receptor Area 23.

Source: CalEEMod Version 2020.4.0. Refer to Appendix A for assumptions used in this analysis.

Operational LST
According to SCAQMD localized significance threshold methodology, LSTs would apply to the operational phase of a proposed project if the project includes stationary sources or attracts mobile sources that may spend extended periods queuing and idling at the site (e.g., warehouse or transfer facilities). The proposed project includes the expansion of a Kaiser Permanente medical facility. As such, nominal amount of truck trips is anticipated at the project site. These truck activities would be intermittent and would not include extended periods of idling time; therefore, idling emissions from truck trips would be minimal. Additionally, potential emergency vehicle trips to and from the project site would be sporadic and would not idle on-site or along adjacent roadways for long periods of time. The project would also include an emergency generator that would only be used during power outage. Although emergency generators have the potential to cause localized air quality impacts, due to the sporadic use of the proposed emergency generator, the impacts would be less than significant. In addition, before operation of the emergency generator, the project Applicant would be required to apply and obtain a stationary source permit from SCAQMD and report criteria pollutants emissions. Thus, due to the lack of major stationary source emissions, no long-term LST analysis is necessary. Operational LST impacts would be less than significant in this regard.

Carbon Monoxide Hotspots
CO emissions are a function of vehicle idling time, meteorological conditions, and traffic flow. Under certain extreme meteorological conditions, CO concentrations near a congested roadway or intersection may reach unhealthful levels (i.e., adversely affecting residents, school children, hospital patients, and the elderly).

The Basin is designated as an attainment/maintenance area for the Federal CO standards and an attainment area for State standards. There has been a decline in CO emissions even though vehicle miles traveled on U.S. urban and rural roads have increased nationwide; estimated anthropogenic CO emissions have decreased 68 percent between 1990 and 2014. In 2014, mobile sources accounted for 82 percent of the nation’s total anthropogenic CO emissions.10 Three major control programs have contributed to 10 United States Environmental Protection Agency¸ Carbon Monoxide Emissions, https://cfpub.epa.gov/roe/indicator_pdf.cfm?i=10, accessed January 11, 2021.

Kaiser Permanente Riverside Medical Center Expansion Project Air Quality Technical Memorandum

Page 29 ends

the reduced per-vehicle CO emissions: exhaust standards, cleaner burning fuels, and motor vehicle inspection/maintenance programs.

A detailed CO analysis was conducted in the Federal Attainment Plan for Carbon Monoxide (CO Plan) for the SCAQMD’s 2003 Air Quality Management Plan, which is the most recent AQMP that addresses CO concentrations. The locations selected for microscale modeling in the CO Plan are worst-case intersections in the Basin and would likely experience the highest CO concentrations. Thus, CO analysis within the CO Plan is utilized in a comparison to the proposed project, since it represents a worst-case scenario with heavy traffic volumes within the Basin.

Of these locations, the Wilshire Boulevard/Veteran Avenue intersection in Los Angeles County experienced the highest CO concentration (4.6 parts per million [ppm]), which is well below the 35-ppm one-hour CO Federal standard. The Wilshire Boulevard/Veteran Avenue intersection is one of the most congested intersections in southern California with an average daily trip volume of approximately 100,000 vehicles per day. As CO hotspots were not experienced at the Wilshire Boulevard/Veteran Avenue intersection, it can be reasonably inferred that CO hotspots would not be experienced at any intersections within the City of Riverside near the project site due to the comparatively low volume of traffic that would occur as a result of project implementation.
11 Therefore, impacts would be less than significant in this regard.

Localized Air Quality Health Impacts
As evaluated above, the project’s air emissions would not exceed the SCAQMD’s LST thresholds, and CO hotpots would not occur as a result of the proposed project. Therefore, the project would not exceed the most stringent applicable Federal or State ambient air quality standards for emissions of CO, NOX, PM10, or PM2.5. It should be noted that the ambient air quality standards are developed and represent levels at which the most susceptible persons (e.g., children and the elderly) are protected. In other words, the ambient air quality standards are purposefully set in a stringent manner to protect children, elderly, and those with existing respiratory problems. Thus, an air quality health impact would be less than significant in this regard.

Conclusion
In conclusion, the project would not expose sensitive receptors to substantial pollutant concentrations as the project would not exceed the SCAQMD LST thresholds, would not cause a CO hotspot, and would not create a localized air quality health impact. A less than significant impact would occur in this regard.

Mitigation Measures: No mitigation is required.

Impact AQ-4: Result in other emissions (such as those leading to odors) adversely affecting a substantial number of people?
Less Than Significant Impact. According to CARB’s Air Quality and Land Use Handbook12, land uses associated with odor complaints typically include agricultural uses, wastewater treatment plants, food processing plants, chemical plants, composting, refineries, landfills, dairies, and fiberglass molding. The proposed project does not include any uses identified by the CARB as being associated with odors.

Construction activities associated with the project may generate detectable odors from heavy-duty equipment exhaust and architectural coatings. However, construction-related odors would be short-term in nature and cease upon project completion. In addition, the project would be required to comply with 11 LSA Associates, Traffic Impact Analysis, Kaiser Permanente Riverside Medical Center Expansion, dated March 2021. 12 California Air Resources Board, Air Quality and Land Use Handbook, April 2005.

the California Code of Regulations, Title 13, Sections 2449(d)(3) and 2485, which minimizes the idling time of construction equipment either by shutting it off when not in use or by reducing the time of idling to no more than five minutes. This would further reduce the detectable odors from heavy-duty equipment exhaust. The project would also comply with the SCAQMD Regulation XI, Rule 1113 – Architectural Coating, which would minimize odor impacts from ROG emissions during architectural coating. Any impacts to existing adjacent land uses would be short-term and are less than significant.

Mitigation Measures: No mitigation is required.

CUMULATIVE IMPACTS
Air pollution is largely a cumulative impact. The nonattainment status of regional pollutants is a result of past and present development, and the SCAQMD develops and implements plans for future attainment of ambient air quality standards. Based on these considerations, project-level thresholds of significance for criteria pollutants are relevant in the determination of whether the project’s individual emissions would have a cumulatively significant impact on air quality. Cumulative air quality impacts may potentially result when the emissions from cumulative projects combine to degrade air quality conditions below attainment levels for the Basin, delay attainment of air quality standards, affect sensitive receptors, or subject surrounding areas to objectionable odors. The cumulative study area for air quality includes the Basin, which is contiguous with the County because air quality is evaluated at the air basin level.

Cumulative impacts on sensitive receptors and odors are more localized and include surrounding areas close to the project site.

With respect to the proposed project’s construction-related air quality emissions and cumulative Basinwide conditions, the SCAQMD adopted the 2016 AQMP which establishes a program of rules and regulations directed at reducing air pollutant emissions and achieving State and Federal air quality standards. As such, the proposed project would comply with SCAQMD rules and regulations, and the adopted 2016 AQMP emissions control measures. Per SCAQMD rules and mandates, as well as the CEQA requirement that significant impacts be mitigated to the extent feasible, these same requirements (i.e., rules and regulations compliance, the implementation of all feasible mitigation measures, and compliance with adopted 2016 AQMP emissions control measures) would also be imposed on construction projects throughout the Basin, including the proposed project.

With respect to the proposed project’s long-term air quality emissions and cumulative Basin-wide conditions, the proposed project would not result in short- or long-term air quality impacts, as emissions would not exceed the SCAQMD adopted thresholds; refer to Table 10, above. Additionally, adherence to SCAQMD rules and regulations would alleviate potential impacts related to cumulative conditions on a project-by-project basis. Emission reduction technology, strategies, and plans are constantly being developed. As a result, the proposed project would not contribute a cumulatively considerable net increase of any nonattainment criteria pollutant. Therefore, the project’s incremental operational impacts would be less than cumulatively considerable and impacts in this regard are less than significant.

MANAGEMENT SUMMARY
In 2020, ECORP Consulting, Inc. was retained to conduct a cultural resources inventory for the proposed Kaiser Permanente Riverside Medical Center Expansion Project in the City of Riverside, Riverside County, California. The proposed Project consists of the redevelopment of approximately 15.5 acres of the existing

37.5-acre Kaiser Permanente Riverside Medical Center property to expand acute care medical service facilities and ancillary use areas. The primary Project Area is within the existing Kaiser Permanente Riverside Medical Center campus (Assessor’s Parcel Number [APN] 138-470-010) located at 10800 Magnolia Avenue, west of Tyler Street, east of La Sierra Avenue, and north of Highway 91. Additional temporary staging areas will be located at 11510 Magnolia Avenue (APN 132-020-033), 10821 Magnolia Avenue (APN 142-293-028), and east of 10493 Magnolia Avenue (APNs 143-180-028 and 143-180-032).

The cultural resources inventory included a records search, literature review, and field survey. A records search of the California Historical Resources Information System at the Eastern Information Center revealed that 28 cultural resources investigations were previously conducted in or within one mile of the Project Area, one of which overlaps the Project Area. Sixteen cultural resources were previously recorded within one mile of the Project Area as a result of these investigations; however, no cultural resources have been previously identified within the Project Area itself. A search of the Sacred Lands File was completed by the California Native American Heritage Commission and resulted in a negative finding, meaning that no Native American Sacred Lands have been recorded in the Project Area. ECORP also performed a pedestrian survey of the on-site development footprint for the hospital buildings and parking structures, as well as a cursory (non-intensive) visit to each of the staging areas.

As a result of the field survey, no cultural resources were recorded in the Project Area. There are no Historical Resources, as defined by the California Environmental Quality Act or Historic Properties, as defined by the National Historic Preservation Act, present within the proposed Project Area.

Recommendations for the management of unanticipated discoveries are provided.

1.0 INTRODUCTION
In 2020, ECORP Consulting, Inc. was retained by Michael Baker International to conduct a cultural resources inventory of the proposed Kaiser Permanente Riverside Medical Center Expansion Project Area in the City of Riverside, California. A survey of the property was required to identify potentially eligible cultural resources (archaeological sites and historic-period buildings, structures, and objects) that could be affected by the Project. ECORP also completed cursory (non-intensive) site visits to proposed staging areas located at 11510 Magnolia Avenue, 10821 Magnolia Avenue, and 10493 Magnolia Avenue.

1.1 Project Location and Description
The primary Project Area consists of 37.5 acres of property located in Sections 18 and 19 of Township 3 South, Range 6 West, San Bernardino Base and Meridian, as depicted on the 1967 photorevised 1980 Riverside West, California, U.S. Geological Survey (USGS) 7.5-minute topographic quadrangle map (Figure 1). It is also known as APN 138-470-010. It is located 10800 Magnolia Avenue, west of Tyler Street, east of La Sierra Avenue and North of Highway 91 in the City of Riverside, Riverside County.

The Project Area is currently developed as the Kaiser Permanente Riverside Medical Center, constructed between 1980 and 1994. The existing medical center includes four buildings located in the center of the property. The existing buildings are surrounded by surface parking lots and one parking structure to the north. Kaiser Permanente is proposing the redevelopment of approximately 15.5 acres of the existing

37.5-acre medical center to expand acute care medical service facilities and ancillary use facilities. The expanded facilities and uses would consist of an approximately 318,433-square foot new multi-story hospital tower, a new diagnostic and treatment (D&T) building, a multi-story 1,200-stall above-ground parking structure, and upgrades to the existing central utility plant. The Project would also include ancillary features such as a new patient drop-off canopy, driveways, walkways, surface parking, landscaping, lighting, and signage as necessary for access, safety, security, and advertisement purposes.

Project construction would occur over an approximate 58-month time frame in two major build phases comprising seven subphases. Construction of the proposed project has two major phases: one for the parking structure and the other for the new hospital tower and D&T building. Table 1, Construction Phases, describes the activities undertaken in each of the two major construction phases and seven subphases. The construction sequences would be as follows: demolition and grading, underground utility work, construction of building structure, interior buildout, exterior façade work, and final site work such as paving, coating, finishing, and/or landscaping. Construction equipment would be delivered to the site on low-bed trucks (e.g., on boom trucks) unless the equipment can be driven to the site. All construction equipment and materials would be stored on-site in designated staging and laydown areas. It is anticipated that the work would be completed between the hours of 7:00 a.m. and 7:00 p.m. on weekdays and between the hours 8:00 a.m. and 5:00 p.m. on Saturdays in accordance with the construction time limitations in the City’s Municipal Code Section 7.35.020(G).

Phases 1-3
Make Ready – Parking
Structure
Phases 1 and 2 include reconfiguring the existing hospital ambulance driveway and hospital patient drop-off area.

A temporary patient drop-off canopy for the hospital and a new patient drop-off area for MOB 2 will be constructed as part of Phase 2.

Following the opening of the new patient drop-off areas, parking reconfiguration and restriping of the ADA parking spots south of MOB 3 and MOB 2 patient drop-off area
would be performed as part of Phase 3.
6 months
Phase 4 Parking Structure
Phase 4 would involve establishing parking structure
laydown areas, demolition of existing surface parking,
grading, construction of the cast-in-place concrete building structure, construction of the interior 2,500 square feet of office space on the first level, and exterior screening elements.
12 months
Phase 5 New Ambulance Driveway
Phase 5 involves the reconfiguration of the existing
hospital ambulance egress and the construction of the new emergency vehicle driveway that will provide access from Magnolia Avenue.
4 months
Phases 6-7
New Hospital Tower, D&T
Building and Entry Plaza
Construction
Phases 6 and 7 involve construction of the new hospital tower and correlating interior and exterior site work, D&T building, upgrades to the existing central utility plant, utility connections from the central utility plant to the new hospital tower and undergrounding of existing aboveground utilities, construction of a new patient entry and drop-off canopy, reconfigured driveways, and landscaping.
36 months
The majority of earthwork would be required during the construction of the basement for the new hospital tower. The total depth of excavation for the basement construction is anticipated to be up to 20 feet below the existing ground surface. Project earthwork would require approximately 9,650 cubic yards of cut and 18,500 cubic yards of fill; thus, approximately 8,850 cubic yards of soil import would be required. The material would be disposed of at an approved landfill facility approximately five miles from the Project site. Grading would be accomplished with scrapers, motor graders, water trucks, dozers, and compaction equipment. Building materials would be off-loaded and installed using small cranes, boom trucks, forklifts, rubber-tired loaders, rubber-tired backhoes, and other small- to medium-sized construction equipment as needed.

At the request of Michael Baker International, ECORP completed non-intensive visits to four proposed offsite staging areas located on Magnolia Avenue (APN 132-020-033, 142-293-028, 143-180-028, and 143- 180-032). The four discontiguous off-site staging areas total 18.9 acres in size. These staging areas will be utilized for the staging and temporary storage of construction equipment and materials during the Cultural Resources Report for the Kaiser Permanente Riverside Medical Center Expansion Project ECORP Consulting, Inc.

development of the proposed Project. The staging areas are either paved or covered with tall grasses that may require vegetation removal.

The City of Riverside (City) will act as the Lead Agency for the Project relative to the California Environmental Quality Act (CEQA).

1.2 Area of Potential Effects
The Area of Potential Effects (APE), or Project Area, consists of the horizontal and vertical limits of a project and includes the area within which significant impacts or adverse effects to Historical Resources or Historic Properties could occur as a result of the project. The APE is defined for projects subject to regulations implementing Section 106 (federal law and regulations). For projects subject to CEQA, the term Project Area is used rather than APE. For the purpose of this document, the terms APE and Project Area are interchangeable.

The horizontal APE consists of all areas where activities associated with a project are proposed and in the case of the current Project, equals the Project Area subject to environmental review under CEQA. This includes areas proposed for construction, vegetation removal, grading, trenching, stockpiling, staging, paving, and other elements described in the official Project description. The horizontal APE is shown on Figure 1 and also represents the survey coverage area. The primary Project Area where construction will take place encompasses 37.5 acres. The four proposed off-site staging areas comprise a total of 18.9 acres and would be primarily used for worker parking.

The vertical APE is described as the maximum depth below the surface to which excavations for project foundations and facilities will extend. Therefore, the vertical APE includes all subsurface areas where archaeological deposits could be affected. The subsurface vertical APE varies across the Project, depending on the depth of the grading or trenching for installation of facilities. This study assumes it could extend as deep as 20 feet below the current surface; therefore, review of geologic and soils maps was necessary to determine the potential for buried archaeological sites that cannot be seen on the surface. There is no anticipated ground disturbance planned for the off-site staging areas.

The vertical APE is also described as the maximum height of structures that could impact the physical integrity and integrity of setting of cultural resources, including districts and traditional cultural properties.

The current study assumes the above-surface vertical APE is up to 110 feet.

1.3 Regulatory Context
To meet the regulatory requirements of this Project, this cultural resources investigation was conducted pursuant to the provisions for the treatment of cultural resources contained within Section 106 of the National Historic Preservation Act (NHPA), CEQA (Public Resources Code [PRC] § 21000 et seq.), Title 20 of the Riverside Municipal Code and the Historic Preservation Element of the General Plan. The goal of NHPA and CEQA is to develop and maintain a high-quality environment that serves to identify the significant environmental effects of the actions of a proposed project and to either avoid or mitigate those significant effects where feasible. CEQA pertains to all proposed projects that require State or local government agency approval, including the enactment of zoning ordinances, the issuance of conditional Cultural Resources Report for the Kaiser Permanente Riverside Medical Center Expansion Project ECORP Consulting, Inc.

Kaiser Permanente Riverside 5

use permits, and the approval of development project maps. The NHPA pertains to projects that entail some degree of federal funding or permit approval.

The NHPA and CEQA (Title 14, California Code of Regulations [CCR], Article 5, § 15064.5) apply to cultural resources of the historical and pre-contact (prehistoric) periods. Any project with an effect that may cause a substantial adverse change in the significance of a cultural resource, either directly or indirectly, is a project that may have a significant effect on the environment. As a result, such a project would require avoidance or mitigation of impacts to those affected resources. Significant cultural resources must meet at least one of four criteria that define eligibility for listing on either the California Register of Historical Resources (CRHR) (PRC § 5024.1, Title 14 CCR, § 4852) or the National Register of Historic Places (NRHP) (36 Code of Federal Regulations [CFR] 60.4). Cultural resources eligible for listing on the NRHP are considered Historic Properties under CFR 36 Part 800 and are automatically eligible for the CRHR.

Resources listed on or eligible for inclusion in the CRHR are considered Historical Resources under CEQA.

Tribal Cultural Resources are defined in Section 21074 of the California PRC as sites, features, places, cultural landscapes (geographically defined in terms of the size and scope), sacred places, and objects with cultural value to a California Native American tribe that are either included in or determined to be eligible for inclusion in the CRHR, or are included in a local register of historical resources as defined in subdivision (k) of Section 5020.1, or are a resource determined by the Lead Agency, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision (c) of Section 5024.1. Section 1(b)(4) of Assembly Bill (AB) 52 established that only California Native American tribes, as defined in Section 21073 of the California PRC, are experts in the identification of Tribal Cultural Resources and impacts thereto. Because ECORP does not meet the definition of a California Native American tribe, this report only addresses information for which ECORP is qualified to identify and evaluate, and that which is needed to inform the cultural resources section of CEQA documents. This report, therefore, does not identify or evaluate Tribal Cultural Resources. Should California Native American tribes ascribe additional importance to or interpretation of archaeological resources described herein, or provide information about non-archeological Tribal Cultural Resources, that information is documented separately in the AB 52 tribal consultation record between the tribe(s) and Lead Agency, and summarized in the Tribal Cultural Resources section of the CEQA document, if applicable.

Title 20 of the Riverside Municipal Code is to promote the public health, safety, and general welfare by providing for the identification, protection, enhancement, perpetuation and use of improvements, buildings, structures, signs, objects, features, sites, places, areas, districts, neighborhoods, streets, works of art, natural features and significant permanent landscaping having special historical archaeological, cultural, architectural, community, aesthetic or artistic value in the City [of Riverside], as defined in Chapter

20.50 of Title 20, Riverside Code of Ordinances.

As a Certified Local Government, the City of Riverside’s historic preservation program as has been recognized by the State Office of Historic Preservation. The Riverside Historic Preservation Element of the Riverside General Plan reinforces the needs of the NHPA, CEQA, and Title 20, and implements these regulations to better preserve the historic nature of the City of Riverside. The General Plan also sets objectives and policies for historic preservation in the City of Riverside.

In accordance with the City of Riverside Consultant Requirements for Cultural Resources Survey, Studies, and Reports, ECORP sent request for information letters to Native American tribes on a list provided in the Native American Heritage Commission (NAHC) Sacred Lands File search results. Letters were sent to 21 tribes and tribal representatives requesting information regarding any archaeological resources, historic resources, or locations that are of cultural importance to the local Native American community located in or near the proposed Project Area.

This report was prepared as a co-compliant document meeting the cultural resources standards and implementing regulations for both NHPA and CEQA.

1.4 Report Organization
The following report documents the study and its findings and was prepared in conformance with the California Office of Historic Preservation’s (OHP) Archaeological Resource Management Reports:

Recommended Contents and Format. Attachment A includes a confirmation of the records search with the California Historical Resources Information System (CHRIS). Attachment B contains documentation of a search of the Sacred Lands File and correspondence with Native American tribes. Attachment C presents photographs of the Project Area. Attachment D contains resumes of report authors and contributing staff.

Sections 6253, 6254, and 6254.10 of the California Code authorize State agencies to exclude archaeological site information from public disclosure under the Public Records Act. In addition, the California Public Records Act (Government Code § 6250 et seq.) and California’s open meeting laws (The Brown Act, Government Code § 54950 et seq.) protect the confidentiality of Native American cultural place information. Under Exemption 3 of the federal Freedom of Information Act (5 U.S. Code [USC] 5), because the disclosure of cultural resources location information is prohibited by the Archaeological Resources Protection Act of 1979 (16 USC 470hh) and Section 307103 of the NHPA, it is also exempted from disclosure under the Freedom of Information Act. Likewise, the Information Centers of the CHRIS maintained by the OHP prohibit public dissemination of records search information.

2.0 SETTING

2.1 Environmental Setting
The primary Project Area is located in the City of Riverside on flat, developed land. The proposed off-site staging areas currently exist as previously disturbed, undeveloped land. The Project Area is located approximately 32 miles northeast of the Pacific Ocean and 96 miles north of the U.S.-Mexico international border in the County of Riverside, California.

2.2 Geology and Soils
Morton and Miller (2006) have mapped the underlying geology of the Project Area as old alluvial-fan deposits, Unit 3 dated to the Pleistocene (2.588-0.0117 Ma). This geologic unit varies across the region based on topographical differences of canyons and valleys, but it is described as moderately dissected interstratified sand and gravel capped soils transitioning to primarily sand- to boulder-sized clasts, Cultural Resources Report for the Kaiser Permanente Riverside Medical Center Expansion Project ECORP Consulting, Inc.

Kaiser Permanente Riverside 7

moderately consolidated and variably dissected. The underlying geology abuts and is overlain by Quaternary valley-fill alluvial deposits dating to both the Pleistocene and Holocene (Qv).

According to the U.S. Department of Agriculture’s Natural Resources Conservation Service (NRCS) Web Soil Survey (NRCS 2021), five soil types are located within the Project Area: Arlington fine sandy loam, deep, 2 to 8 percent slopes; Buchenau loam, slightly saline-alkali, 0-2 percent slopes; Buchenau loam, slightly saline-alkali, 2-8 percent slopes; Greenfield sandy loam, 0-2 percent slopes; and Hanford fine sandy loam, 0-2 percent slopes. These soils are classified as alluvials and result from flooding events in alluvial plains. The potential exists for buried pre-contact archaeological sites in the Project Area due to regional occupation by Native Americans contemporaneous with the emplacement of alluvial sediments during the Holocene.

3.0 CULTURAL CONTEXT

3.1 Regional Pre-Contact History
The archaeological history of southern California is remarkably complex, with a great deal of variation and the overlapping of specific technological and cultural traditions from the onset of documented human habitation in the terminal Pleistocene to the period of European contact in the Late Holocene. Today, archaeology and culture history are typically described according to geological epoch, with delineations in years before present (BP) between the Pleistocene (more than 10,000 BP), Early Holocene (10,000 to 6,500 BP), Middle Holocene (6,500 to 3,500 BP) and the Late Holocene (3,500 BP to present). This approach places human history squarely in the realm of greater ecology and geological history in a way that allows discussion of human activity through time without limitations imposed by provincial labels. In California, this distinct use of geological terminology is not entirely arbitrary, as elements of technological change and diversification in cultural practices are observable at the transition of temporal periods (Erlandson and Colten 1991). However, terminology that is generally accepted by California archaeologists and the California OHP is still helpful in describing ancient patterns of human activity. The predominant archaeological patterns through time in relation to behavioral traditions and temporal periods, and in specific reference to the Project Area, are discussed below.

3.2 Local Pre-Contact History

3.2.1 Paleo-Indian Period/Terminal Pleistocene (12,000 to 10,000 BP) The first inhabitants of southern California were big-game hunters and gatherers exploiting now-extinct species of Pleistocene megafauna (e.g., mammoth and other Rancholabrean fauna). Local "fluted point" assemblages comprised of large spear points or knives are stylistically and technologically similar to the Clovis Paleo-Indian cultural tradition dated to this period elsewhere in North America (Moratto 1984).

Archaeological evidence for this period in southern California is limited to a few small temporary camps with fluted points found around late Pleistocene lake margins in the Mojave Desert and around Tulare Lake in the southern San Joaquin Valley. Single points are reported from Ocotillo Wells and Cuyamaca Pass in eastern San Diego County and from the Yuha Desert in Imperial County (Rondeau et al. 2007).

3.2.2 Early Archaic Period/Early Holocene (10,000 to 8,500 BP) Approximately 10,000 years ago, at the beginning of the Holocene, warming temperatures, and the extinction of the megafauna resulted in changing subsistence strategies with an emphasis hunting smaller game and increasing reliance on plant gathering. Previously, Early Holocene sites were represented by only a few sites and isolates from the Lake Mojave and San Dieguito complexes found along former lakebeds and grasslands of the Mojave Desert and in inland San Diego County. More recently, southern California Early Holocene sites have been found along the Santa Barbara Channel (Erlandson 1994), in western Riverside County (Goldberg 2001, Grenda 1997), and along the San Diego County coast (Gallegos 1991, Koerper et al. 1991, Warren 1967).

The San Dieguito Complex was defined based on material found at the Harris site (CA-SDI-149) on the San Dieguito River near Lake Hodges in San Diego County. San Dieguito artifacts include large leafshaped points; leaf-shaped knives; large ovoid, domed, and rectangular end and side scrapers; engraving tools; and crescentics (Koerper et al. 1991). The San Dieguito Complex at the Harris site dates to 9,000 to 7,500 BP (Gallegos 1991:Figure 3.9). However, sites from this time period in coastal San Diego County have yielded artifacts and subsistence remains characteristic of the succeeding Encinitas Tradition, including manos, metates, core-cobble tools, and marine shell (Gallegos 1991; Koerper et al. 1991).

3.2.3 Encinitas Tradition or Milling Stone Period/Middle Holocene (8,500 to 1,250 BP) The Encinitas Tradition (Warren 1968) and the Milling Stone Period (Wallace 1955) refer to a long period of time during which small mobile bands of people who spoke an early Hokan language foraged for a wide variety of resources including hard seeds, berries, and roots/tubers (yucca in inland areas), rabbits and other small animals, and shellfish and fish in coastal areas. Sites from the Encinitas Tradition consist of residential bases and resource acquisition locations with no evidence for overnight stays. Residential bases have hearths and fire-affected rock indicating overnight stays and food preparation. Residential bases along the coast have large amounts of shell and are often termed shell middens.

The Encinitas Tradition as originally defined (Warren 1968) applied to all of the non-desert areas of southern California. Recently, four patterns within the Encinitas Tradition have been proposed that apply to different regions of southern California (Sutton and Gardner 2010). The Topanga Pattern includes archaeological material from the Los Angeles Basin and Orange County. The Greven Knoll Pattern pertains to southwestern San Bernardino County and western Riverside County (Sutton and Gardner 2010). Each of the patterns is divided into temporal phases. The Topanga Pattern included the Los Angeles Basin and Orange County. The Topanga I phase extends from 8,500 to 5,000 BP and Topanga II runs from 5,000 to 3,500 BP. The Topanga Pattern ended about 3,500 BP with the arrival of Takic speakers, except in the Santa Monica Mountains where the Topanga III phase lasted until about 2,000 BP.

The Encinitas Tradition in inland areas east of the Topanga Pattern (southwestern San Bernardino County and western Riverside County) is the Greven Knoll Pattern (Sutton and Gardner 2010). Greven Knoll I (9,400 to 4,000 BP) has abundant manos and metates. Projectile points are few and are mostly Pinto points. Greven Knoll II (4,000 to 3,000 BP) has abundant manos and metates and core tools. Projectile points are mostly Elko points. The Elsinore site on the east shore of Lake Elsinore was occupied during Cultural Resources Report for the Kaiser Permanente Riverside Medical Center Expansion Project ECORP Consulting, Inc.

Greven Knoll I and Greven Knoll II. During Greven Knoll I faunal processing (butchering) took place at the lakeshore and floral processing (seed grinding), cooking, and eating took place farther from the shore.

The primary foods were rabbit meat and seeds from grasses, sage, and ragweed. A few deer, waterfowl, and reptiles were consumed. The recovered archaeological material suggests that a highly mobile population visited the site at a specific time each year. It is possible that their seasonal round included the ocean coast at other times of the year. These people had an unspecialized technology as exemplified by the numerous crescents, a multi-purpose tool. The few projectile points suggest that most of the small game was trapped using nets and snares (Grenda 1997:279). During Greven Knoll II, which included a warmer drier climatic episode known as the Altithermal, it is thought that populations in interior southern California concentrated at oases and that Lake Elsinore was one of them. The Elsinore site (CA-RIV-2798) is one of five known Middle Holocene residential sites around Lake Elsinore. Tools were mostly manos, metates, and hammerstones. Scraper planes were absent. Flaked-stone tools consisted mostly of utilized flakes used as scrapers. The Elsinore site during the Middle Holocene was a “recurrent extended encampment” that could have been occupied during much of the year.

The Encinitas Tradition lasted longer in inland areas because Takic speakers did not move east into these areas until circa 1,000 BP. Greven Knoll III (3,000 to 1,000 BP) is present at the Liberty Grove site in Cucamonga (Salls 1983) and at sites in Cajon Pass that were defined as part of the Sayles Complex (Kowta 1969). Greven Knoll III sites have a large proportion of manos and metates and core tools as well as scraper planes. Kowta (1969) suggested the scraper planes may have been used to process yucca and agave. The faunal assemblage consists of large quantities of lagomorphs (rabbits and hares) and lesser quantities of deer, rodents, birds, carnivores, and reptiles.

3.2.4 Palomar Tradition (1,250 to 150 BP)
The native people of southern California (north of a line from Agua Hedionda to Lake Henshaw in San Diego County) spoke Takic languages, which form a branch or subfamily of the Uto-Aztecan language family. The Takic languages are divided into the Gabrielino-Fernandeño language, the Serrano-Kitanemuk group (the Serrano [includes the Vanyume dialect] and Kitanemuk languages), the Tataviam language, and the Cupan group (the Luiseño-Juaneño language, the Cahuilla Language, and the Cupeño language) (Golla 2011). According to Sutton (2009), Takic speakers occupied the southern San Joaquin Valley before 3,500 BP. Perhaps as a result of the arrival of Yokutsan speakers (a language in the Penutian language family) from the north, Takic speakers moved southeast. The ancestors of the Kitanemuk moved into the Tehachapi Mountains and the ancestors of the Tataviam moved into the upper Santa Clara River drainage.

The ancestors of the Gabrielino (Tongva) moved into the Los Angeles Basin about 3,500 BP, replacing the native Hokan speakers. Speakers of proto-Gabrielino reached the southern Channel Islands by 3,200 BP (Sutton 2009) and moved as far south as Aliso Creek in Orange County by 3,000 BP.

Takic people moved south into southern Orange County after 1,250 BP and became the ancestors of the Juaneño. Takic people moved inland from southern Orange County about 1,000 BP, becoming the ancestors of the Luiseño, Cupeño, and Cahuilla. Takic people from the Kitanemuk area moved east along the northern slopes of the San Gabriel Mountains and spread into the San Bernardino Mountains and along the Mojave River, becoming the ancestors of the Serrano and the Vanyume.

The material culture of the inland areas where Takic languages were spoken at the time of Spanish contact is part of the Palomar Tradition (Sutton 2011). San Luis Rey I Phase (1,000 to 500 BP) and San Luis Rey II Phase (500 to 150 BP) pertain to the area occupied by the Luiseño at the time of Spanish contact.

The Peninsular I (1,000 to 750 BP), II (750 to 300 BP), and III (300 to 150 BP) Phases are used in the areas occupied by the Cahuilla and Serrano (Sutton 2011).

San Luis Rey I is characterized by Cottonwood Triangular arrow points, use of bedrock mortars, stone pendants, shell beads, quartz crystals, and bone tools. San Luis Rey II sees the addition of ceramics, including ceramic cremation urns, red pictographs on boulders in village sites, and steatite arrow straighteners. San Luis Rey II represents the archaeological manifestation of the antecedents of the historically known Luiseño (Goldberg 2001:I-43). During San Luis Rey I there were a series of small permanent residential bases at water sources, each occupied by a kin group (probably a lineage). During San Luis Rey II people from several related residential bases moved into a large village located at the most reliable water source (Waugh 1986). Each village had a territory that included acorn harvesting camps at higher elevations. Villages have numerous bedrock mortars, large dense midden areas with a full range of flaked and ground stone tools, rock art, and a cemetery.

3.3 Ethnohistory
Ethnographic accounts of Native Americans indicate that the Project Area lies predominantly within the original territory of the Cahuilla (Bean 1978), although portions of the City of Riverside are also claimed by the Gabrieleno, Luiseño, and Serrano.

3.3.1 Cahuilla
The Cahuilla spoke a Takic language. The Takic group of languages is part of the Uto-Aztecan language family. The Cahuilla occupied a territory ranging from the San Bernardino Mountains in the north to the Chocolate Mountains and Borrego Springs in the south, and from the Colorado Desert in the east to Palomar Mountain in the west. They engaged in trade, marriage, shared rituals, and war with other groups of Native Americans whose territories they overlapped, primarily the Serrano and Gabrielino (Bean 1978, 1972; Kroeber 1925).

Cahuilla subsistence consisted of hunting, gathering, and fishing. Villages were often located near water sources, most commonly in canyons or near drainages on alluvial fans. Major villages were fully occupied during the winter, but during other seasons task groups made periodic forays to collect various plant foods, with larger groupings from several villages organizing for the annual acorn harvest (Bean and Saubel 1972). Bean and Saubel (1972) have recorded the use of several hundred species of plants used for food, building/artifact materials, and medicines. The major plant foods included acorns, pinyon nuts, and various seed-producing legumes. These were complemented by agave, wild fruits and berries, tubers, cactus bulbs, roots and greens, and seeds.

Hunting focused on both small to medium-sized mammals such as rodents and rabbits, and large mammals such as pronghorn sheep, mountain sheep, and mule deer. Hunting was done using the throwing stick or the bow and arrow, though nets and traps were also used for small animals (Bean 1972).

Cultural Resources Report for the Kaiser Permanente Riverside Medical Center Expansion Project ECORP Consulting, Inc.

Kaiser Permanente Riverside 11 June 20212020-233
Cahuilla buildings consisted of dome-shaped or rectangular houses, constructed of poles covered with brush and above-ground granaries (Bean 1978; Strong 1929). Other material culture included baskets, pottery, and grinding implements; stone tools, arrow shaft straighteners and bows; clothing (loincloths, blankets, rope, sandals, skirts, and diapers); and various ceremonial objects made from mineral, plant, and animal substances (Bean 1972).

As many as 10,000 Cahuilla may have existed at the time of European contact in the eighteenth century (Bean 1978). Circa 1900, Cahuilla lived in the settlements of La Mesa, Toro, and Martinez on the Augustin and Toro Indian Reservations east and southeast of the Project Area (USGS Indio Quad 1904). As of 1974, approximately 900 people claimed Cahuilla ancestry (Bean 1978).

There was no substantial Euro-American settlement in the Coachella Valley until the Southern Pacific Railroad completed its line from Los Angeles to Indio (then known as Indian Wells) in 1876. The railroad was completed to Yuma in 1877, linking southern California with Arizona and points east. Wells to supply water for the steam locomotives were dug at Indio, Coachella (originally named Woodspur), Thermal (originally named Kokell), and Mecca (originally named Walters). Settlement began around these wells and railroad stations, forming the nucleus of today’s Coachella Valley towns.

3.3.2 Gabrieleno
At the time of contact with Europeans, the Gabrieleno were the main occupants of the southern Channel Islands, the Los Angeles basin, much of Orange County, and extended as far east as the western San Bernardino Valley. The term “Gabrieleno” came from the group’s association with Mission San Gabriel Arcangel, established in 1771. The Gabrieleno are believed to have been one of the most populous and wealthy Native American tribes in southern California prior to European contact. (Bean and Smith 1978a; McCawley 1996; Moratto 1984). The Gabrielino spoke a Takic language. The Takic group of languages is part of the Uto-Aztecan language family.

The Gabrieleno occupied villages located along rivers and at the mouths of canyons. Populations ranged from 50 to 200 inhabitants. Residential structures within the villages were domed, circular, and made from thatched tule or other available wood. Gabrielino society was organized by kinship groups, with each group composed of several related families who together owned hunting and gathering territories.

Settlement patterns varied according to the availability of floral and faunal resources (Bean and Smith 1978a; McCawley 1996; Miller 1991).

Vegetal staples consisted of acorns, chia, seeds, piñon nuts, sage, cacti, roots, and bulbs. Animals hunted included deer, antelope, coyote, rabbits, squirrels, rodents, birds, and snakes. The Gabrieleno also fished and collected marine shellfish (Bean and Smith 1978a; McCawley 1996; Miller 1991).

By the late 18th century, Gabrieleno population had significantly dwindled due to introduced European diseases and dietary deficiencies. Gabrieleno communities disintegrated as families were taken to the missions (Bean and Smith 1978a; McCawley 1996; Miller 1991). However, current descendants of the Gabrieleno are preserving Gabrieleno culture.

3.3.3 Luiseño
The Luiseño are a Takic-speaking people who occupied what is now western Riverside County and northern San Diego County (the San Luis Rey River drainage) in prehistoric and historic times. The term Luiseño was given by the Spanish to the native groups who were living in this area and who were forcibly removed to Mission San Luis Rey. The Luiseño believe the world was created in the area now known as Temecula and that they have been here since the beginning of time.

The Luiseño lived in sedentary and autonomous village groups, each with specific subsistence territories encompassing hunting, collecting, and fishing areas. Villages were typically located in valley bottoms, along streams, or along coastal strands near mountain ranges where water was available and village defense was possible. Inland populations had access to fishing and gathering sites on the coast, which they used during the winter months (Bean and Shipek 1978).

Luiseño subsistence was centered around the gathering of acorns, seeds, greens, bulbs, roots, berries, and other vegetal foods. This was supplemented with hunting mammals such as deer, antelope, rabbit, woodrat, ground squirrels, and mice, as well as quail, doves, ducks, and other birds. Bands along the coast also exploited marine resources, such as sea mammals, fish, crustaceans, and mollusks. Inland, trout and other fish were taken from mountain streams (Bean and Shipek 1978).

Hunting was carried out both individually and by organized groups. Tool technology for food acquisition, storage, and preparation reflects the size and quantity of items procured. Small game was hunted with the use of curved throwing sticks, nets, slings, or traps. Bows and arrows were used for hunting larger game.

Dugout canoes, basketry fish traps, and shell hooks were used for near-shore ocean fishing. Coiled and twined baskets were made for food gathering, preparation, storing, and serving. Other items used for food processing included large shallow trays for winnowing chaff from grain, ceramic and basketry storage containers, manos and metates for grinding seeds, and ceramic jars for cooking (Bean and Shipek 1978).

Villages had hereditary chiefs who controlled religious, economic, and territorial activities (Bean and Shipek 1978, Boscana 1933). An advisory council of ritual specialists and shamans was consulted for environmental and other knowledge. large villages located along the coast or in inland valleys may have had more complex social and political structures than settlements controlling smaller territories (Bean and Shipek 1978, Strong 1929).

Most Luiseño villages contained a ceremonial structure, enclosed by circular fencing and located near the center of the village. Houses were semisubterranean and thatched with locally available brush, bark, or reeds. Earth-covered semisubterranean sweathouses were also common and were used for purification and curing rituals (Bean and Shipek 1978).

The Luiseño first came into contact with Europeans in 1769 when the expedition led by Gaspar de Portolá arrived in their territory. That same year, the San Diego Mission was established just to the south, followed by the San Juan Capistrano Mission in 1776 and the San Luis Rey Mission in 1798. Poor living conditions at the missions and introduced European diseases led to a rapid decline of the Luiseño population.

Following the Mission Period (1769-1834), Luiseño Indians scattered throughout southern California.

Some became serfs on the Mexican ranchos, others moved to newly founded pueblos established for them, some sought refuge among inland groups, and a few managed to acquire land grants. Later, many moved to or were forced onto reservations. Although many of their cultural traditions had been suppressed during the Mission Period, the Luiseño were successful at retaining their language and certain rituals and ceremonies. Starting in the 1970s, there was a revival of interest in the Luiseño language and classes were organized. Since then, traditional games, songs, and dances have been performed, traditional foods have been gathered and prepared, and traditional medicines and curing procedures have been practiced (Bean and Shipek 1978).

3.3.4 Serrano
The Serrano occupied an area in and around the San Bernardino Mountains and northward into the Mojave Desert. Their territory also extended west along the north slope of the San Gabriel Mountains, east as far as Twentynine Palms, north into the Victorville and Lucerne Valley areas, and south to the Yucaipa Valley and San Jacinto Valley (Cultural Systems Research 2005). The Serrano speakers in the Mojave Desert who lived along the Mojave River were known as Vanyume. Serrano is a language within the Takic family of the Uto-Aztecan language stock.

The Serrano were mainly hunters and gatherers who occasionally fished. Game hunted included mountain sheep, deer, antelope, rabbits, small rodents, and various birds, particularly quail. Vegetable staples consisted of acorns, pinyon nuts, bulbs and tubers, shoots and roots, juniper berries, mesquite, barrel cacti, and Joshua tree (Bean and Smith 1978b).

A variety of materials were used for hunting, gathering, and processing food, as well as for shelter, clothing, and luxury items. Shells, wood, bone, stone, plant materials, and animal skins and feathers were used for making baskets, pottery, blankets, mats, nets, bags and pouches, cordage, awls, bows, arrows, drills, stone pipes, musical instruments, and clothing (Bean and Smith 1978b).

Settlement locations were determined by water availability, and most Serranos lived in villages near water sources. Houses and ramadas were round and constructed of poles covered with bark and tule mats (Kroeber 1925). Most Serrano villages also had a ceremonial house used as a religious center. Other structures within the village might include granaries and sweathouses (Bean and Smith 1978b).

Serrano social and political units were clans, patrilineal exogamous territorial groups. Each clan was led by a chief who had both political and ceremonial roles. The chief lived in a principal village within the clan’s territory. The clans were part of a moiety system such that each clan was either a wildcat or coyote clan and marriages could only occur between members of opposite moieties (Earle 2004). On the north side of the San Bernardino Mountains, clan villages were located along the desert-mountain interface on Deep Creek, on the upper Mojave River, in Summit Valley, and in Cajon Pass. The principal plant food available near these villages was juniper berries. These villages also had access to mountain resources, such as acorns and pinyon nuts.

Partly due to their mountainous and desert inland territory, contact between Serrano and Euro-Americans was minimal prior to the early 1800s. In 1819, an asistencia (mission outpost) was established near present-day Redlands and was used to help relocate many Serrano to Mission San Gabriel. However, Cultural Resources Report for the Kaiser Permanente Riverside Medical Center Expansion Project ECORP Consulting, Inc.

Kaiser Permanente Riverside 14 June 20212020-233
small groups of Serrano remained in the area northeast of the San Gorgonio Pass and were able to preserve some of their native culture. Today, most Serrano live either on the Morongo or San Manuel reservations (Bean and Smith 1978).

3.4 Regional History
The first significant European settlement of California began during the Spanish Period (1769 to 1821) when 21 missions and four presidios were established between San Diego and Sonoma. Although located primarily along the coast, the missions dominated the majority of the California region during this period.

The purpose of the missions and presidios was to establish Spanish economic, military, political, and religious control over the Alta California territory. This included the forced conversion of the native population to Spanish colonial society and Catholicism, which often consisted of subjugating Indians into a life of servitude to Spanish citizens (Castillo 1978; Cleland 1941).

The Mexican Period (1821 to 1848) began with the success of the Mexican Revolution in 1821, but changes to the mission system were slow to follow. When secularization of the missions occurred in the 1830s, the vast land holdings of the missions in California were divided into large land grants called ranchos. The Mexican government granted ranchos throughout California to Spanish and Hispanic soldiers and settlers (Castillo 1978).

In 1848, the Treaty of Guadalupe Hidalgo ended the Mexican-American War and marked the beginning of the American Period (1848 to present). The discovery of gold the same year initiated the 1849 California Gold Rush, bringing thousands of miners and settlers to California, most of who settled in the north. For those settlers who chose to come to southern California, much of their economic prosperity was fueled by cattle ranching rather than by gold. This prosperity, however, came to a halt in the 1860s as a result of severe floods and droughts, which put many ranchers into bankruptcy (Castillo 1978; Cleland 1941).

3.5 Local History
La Placita (Agua Mansa) was the earliest community to be founded in what was later to become Riverside County. Hispanicized Indian settlers from Abiquiu, New Mexico, traveled the Old Spanish Trail following an invitation from the Lugo family of Rancho San Bernardino. In exchange for land, the New Mexican immigrants were to protect the rancho’s cattle and other assets from theft by local Indians and others.

The settlers formed a colony in 1843, but disputes soon arose with the Lugos over water and irrigation rights. In 1844 or 1845, Don Juan Bandini of Rancho Jurupa offered the settlers better land and water rights on the south bank of the Santa Ana River. The New Mexicans, disappointed in their dealings with the Lugos, accepted the offer, known as the Bandini Donation. Led by Lorenzo Trujillo, the settlers formed the community of La Placita (Gunther 1984; Harley 1991; Waitman 1991). The riverbank location proved to be ill-chosen when the adobe town was wiped out during the disastrous flood of 1862 (Clark 1978/1979; Ahlborn 1982). However, the residents of La Placita quickly rebuilt.

The area of La Sierra adjacent to the Project Area was originally a part of the Mexican land grant La Sierra (Sepulveda) as granted by Governor Pio Pico to Vicente Sepulveda in 1846, and patented to Vicente Sepulveda in 1877 (Lech 2012). By 1909, Willits Hole owned the entirety of the La Sierra (Sepulveda) Cultural Resources Report for the Kaiser Permanente Riverside Medical Center Expansion Project ECORP Consulting, Inc.

Kaiser Permanente Riverside 15 June 20212020-233
rancho, and he began to sell off approximately 6,000 acres while developing Hole Ranch. Hole Ranch was primarily centered on agriculture and the accompanying irrigation infrastructure (Tibbet et al. 2008).

In 1870, a few years after La Placita was rebuilt following the flood, the community of Riverside was founded two miles to the south. Due to a few select deaths of those involved in the beginnings of silk production of the area, John North and the Southern California Colony Association purchased the land in 1870 to begin a settlement where education and harmony went hand-in-hand (Lech 2020) This became known as the Colony. In 1883, Riverside Heights, later known as Merrill, and finally as Highgrove, was established (Gunther 1984). The area became one of the first citrus growing centers in the country, an activity helped by the arrival of the Southern Pacific Railroad in the 1870s and the Santa Fe Railroad in the 1880s. Communications, travel, and shipping were opened by the railroad between the Riverside/San Bernardino area and Los Angeles, as well as other regions of the country. A land boom brought about by cheap rail fares and aggressive real estate promotions were in progress by the late 1880s. Irrigation was expanded with construction of the Riverside Upper and Lower Canals, both dug in the 1870s, and the Riverside-Warm Creek Canal, dug in 1886. In 1893, Riverside became the seat of government when Riverside County was formed (Gunther 1984; Brown 1985).

In the following decades, the local citrus industry grew and agriculture was the predominant economy of the area. The Great Depression in the 1930s, however, brought hardships to the region and some farmers were forced to sell their orchards. During the U.S. involvement in World War II, the San Bernardino area was made headquarters of the Western Defense Command because of its safe distance from the threat of an aircraft carrier-based aerial attack and its status as a regional rail, highway, and communications hub.

The economy of the Riverside/San Bernardino area was boosted by military establishments such as the U.S. Army Air Depot (Norton Air Force Base) and the U.S. Army Base General Depot (Camp Ono) in San Bernardino, and March Field (March Air Force Base) south of Riverside (Belden 1963; Brown 1985).

Following World War II, agriculture declined as industrial and suburban development increased. In the 1950s and 1960s, in particular, construction of State Highways 91 and 60 through the area stimulated new housing and commercial growth, and Riverside stretched southward and northward along the freeway. By the 1980s, the expanding city limits had reached northward to the Riverside/San Bernardino County Line (Brown 1985). Agriculture had nearly disappeared.

4.3 Sacred Lands File Coordination Methods
ECORP contacted the California NAHC on January 05, 2021 to request a search of the Sacred Lands File for the Project Area (Attachment B). This search will determine whether or not Sacred Lands have been recorded by California Native American tribes within the APE, because the Sacred Lands File is populated by members of the Native American community who have knowledge about the locations of tribal resources. In requesting a search of the Sacred Lands File, ECORP solicited information from the Native American community regarding tribal cultural resources, but the responsibility to formally consult with the Native American community lies exclusively with the federal and local agencies under applicable State and federal law. ECORP was not delegated authority by the lead agency to conduct tribal consultation.

4.4 Field Methods
On February 26, 2021, ECORP subjected the 37.5-acre primary Project Area to a pedestrian survey under the guidance of the Secretary of the Interior's Standards for the Identification of Historic Properties (NPS 1983). At that time, exposed ground surfaces were examined for indications of surface or subsurface cultural resources. The general morphological characteristics of the ground surface were inspected for indications of subsurface deposits that may be manifested on the surface, such as circular depressions or ditches. Whenever possible, the locations of subsurface exposures caused by such factors as rodent activity, water or soil erosion, or vegetation disturbances were examined for artifacts or for indications of buried deposits. No subsurface investigations or artifact collections were undertaken during the pedestrian survey of the primary Project Area.

At the request of Michael Baker International, ECORP also completed cursory site visits to the four proposed staging areas located on Magnolia Avenue, properties totaling 18.9 acres in size. These staging areas were not subjected to an intensive pedestrian survey but were examined briefly from the edge of the public right-of-way and through historic aerial photographs and maps. Proposed staging areas Cultural Resources Report for the Kaiser Permanente Riverside Medical Center Expansion Project ECORP Consulting, Inc.

include both paved and unpaved surfaces. No construction-related ground disturbance is proposed for the staging areas, though vegetation removal may be necessary in unpaved portions of the staging areas.

5.0 RESULTS

5.1 Records Search
The results of the CHRIS records search were received by ECORP on February 19, 2021 (Attachment A).

The records search consisted of a review of previous research and literature, and records on file with the EIC for previously recorded cultural resources within one mile of the Project Area.

5.1.1 Previous Research
Twenty-eight previous cultural resource investigations have been conducted within one mile of the Project Area between 1994 and 2016. One previous cultural resources investigation overlaps the Project Area (RI-05965). The previous study was a cultural resources overview study and archaeological sensitivity assessment completed in 2003. A pedestrian survey was warranted as part of the current inventory because the previous investigation encompassing the Project Area was completed 18 years ago as a broad reconnaissance-level study. A list of previous cultural resource investigations identified during this records search may be found in Attachment A.

The CHRIS records search also determined that 16 previously recorded cultural resources are located within one mile of the Project Area (Table 2). Previously recorded resources are comprised of four precontact sites, 11 historic-period sites and features, and one multi-component site. No previously recorded resources are located within the Project Area. Details of all nine previously recorded resources are included in Table 2.

5.1.2 Map Review and Aerial Photographs
The review of historic aerial photographs and maps of the Project Area provide information on the past land uses of the property and potential for buried archaeological sites. Based on this information, the property was in use as agricultural land as recent as 1967. However, structures are also visible in the main Project Area and staging areas in the 1966 and 1967 historic aerial photographs.

Following is a summary of the review of historical maps and photographs.  The 1901 USGS Riverside, California 15-minute series topographic quadrangle map (1:62,500 scale) depicts the primary Project Area as undeveloped. The Project Area is located within the City of Riverside. Magnolia Street is visible on this map.
 The 1942 USGS Riverside West, California 1:31600 scale topographic quadrangle map shows one structure at staging area APN 132-020-033.
 The 1953 (photorevised 1962) USGS Riverside West, California 7.5-minute series topographic quadrangle map shows La Sierra Street as named Taylor Street.  The 1967 (photorevised 1969) USGS Riverside West, California 7.5-minute series topographic quadrangle map shows three structures at staging area APN 132-020-033.  An aerial photograph from 1942 shows the hospital campus and the staging areas as agricultural.

One structure is visible at staging area APN 132-020-033.  An aerial photograph from 1966 shows three structures at staging area APN 132-020-033; agriculture and one structure on the hospital campus; agriculture and one structure at staging areas APN 143-180-028 and APN 143-180-032; and one structure at staging area APN 142-293- 028.
 An aerial photograph from 1967 is the same as in 1966.  An aerial photograph from 1980 shows the main hospital campus as agriculture with one structure; three structures at staging area APN 132-020-033; a developed commercial lot with a large building and parking areas at APN 143-180-028 and smaller structures with parking lots at APN 143-180-032; and a structure at staging area APN 142-293-028.  An aerial photograph from 1994 shows the Kaiser main campus developed in its current location within the Project Area.

In summary, the property was used for agriculture beginning in the 1900s and by 1942 a residence was constructed at APN 132-020-033, with other structures built on other areas of the Project Area prior to 1970. No structures exist at the off-site staging areas today. The Kaiser Permanente Riverside Medical Facility was constructed between 1980 and 1994.

5.2 Sacred Lands File Results
The results of the Sacred Lands File search by the NAHC were received on January 20, 2021. The search of the Sacred Lands File was negative and indicated no known presence of Native American cultural resources in the APE. A record of all correspondence is provided in Attachment B.

In accordance with the City of Riverside Consultant Requirements for Cultural Resources Survey, Studies, and Reports, ECORP sent request for information letters to Native American tribes on the list provided in the NAHC Sacred Lands File search results. Letters were sent to 21 tribes and tribal representatives on February 12, 2021, requesting information regarding any archaeological resources, historic resources, or locations that are of cultural importance to the local Native American community located in or near the proposed Project Area. Information was requested within 30 days of receipt of the letter.

As of the time of submission of this report, three responses have been received by ECORP. Jill McCormick of the Quechan Tribe of the Fort Yuma Reservation responded by email on February 17, 2021 and stated that the tribe had no comments on the Project and defers to other tribes. Cheryl Madrigal of the Rincon Band of Luiseño Indians responded by email on February 24, 2021, stating that Rincon does not have knowledge of cultural resources in the area; however, the tribe requests that an archaeological records search be completed and that the results of the records search be sent to the tribe. Documentation of this request may be found in Attachment B. ECORP did not transmit any project-related documents to the tribe. Arysa Gonzalez Romero of the Agua Caliente Band of Cahuilla Indians responded on March 11, 2021 and stated that the Project Area is not located within Agua Caliente’s traditional use area and deferred to other tribes regarding any consultation. All tribal correspondence may be found in Attachment B.

5.3 Field Survey Results
ECORP surveyed the 37.5-acre primary Project Area and additional staging areas on February 26, 2021.

The pedestrian survey was conducted by walking all accessible areas of the Project Area in east-to-west transects where possible and examining both permeable and impermeable surfaces throughout. ECORP expended one-half person-day in the field.

All areas of the Project Area were developed or previously modified (i.e., graded), and no unmodified natural or native surfaces were apparent during the survey (Figures 2 through 6). The majority of the primary Project Area is currently developed with modern buildings and appurtenant features as part of the Kaiser Permanente Riverside Medical Center complex. Staging areas are comprised of previously developed land that has since been cleared and graded. Invasive weeds and other plants have taken root in permeable surfaces and are dispersed intermittently across the staging area parcels. The Project Area is surrounded by recently developed multi-unit residential and commercial properties.

Overall, the surface visibility throughout open areas of the Project Area was excellent (approximately 90 to 100 percent). The majority of the Project Area surface was comprised of impermeable concrete and asphalt paving. Visible soil appeared as highly disturbed local material that has been graded or transported throughout the Project Area, though fill material may have been imported at some point in the past to build up the grade in this highly developed region. No pre-contact or historic-period cultural resources were identified as a result of the field survey.

6.0 MANAGEMENT CONSIDERATIONS

6.1 Conclusions
ECORP conducted a cultural resources inventory consisting of a CHRIS records search, a search of the Sacred Lands File by the NAHC, a field survey of the primary Project Area, and a cursory field visit of the proposed off-site staging areas. No previously recorded cultural resources were identified in the Project Area by the CHRIS records search. No sacred lands were identified during the NAHC search of the Sacred Lands File. No pre-contact or historic-period cultural resources were identified during the field survey or cursory field visits.

Based on these findings, the proposed Project will not disturb any known Historical Resources as defined under CEQA or Historic Properties as defined by Section 106 of NHPA. No ground disturbance should occur until the lead agencies concur with this finding.

6.2 Likelihood for Subsurface Cultural Resources
All portions of the Project Area are highly developed with modern buildings and appurtenant features or highly disturbed due to prior development and demolition, grading, and other relatively recent modification activities. The off-site staging areas were not subjected to intensive pedestrian survey but exhibit a lower likelihood for the presence of cultural resources. However, the potential still exists for buried cultural resources within the Project Area. The CHRIS records search results revealed 16 cultural resources within a one-mile radius of the Project Area. Five of these previously recorded resources have Cultural Resources Report for the Kaiser Permanente Riverside Medical Center Expansion Project ECORP Consulting, Inc.

Kaiser Permanente Riverside 25 June 20212020-233
pre-contact components associated with Native American occupation of the region prior to European contact. Surface sediments in the Project Area consist of Pleistocene and Holocene surficial sediments contemporaneous with human occupation of the region. Due to the disturbed and developed nature of the Project Area, there is a low potential for both historic-period and pre-contact resources to exist subsurface. Post-review discovery procedures are outlined below.

6.3 Recommended Mitigation Measures

6.3.1 Post-Review Discovery Procedures
If subsurface deposits believed to be cultural or human in origin are discovered during construction, all work must halt within a 50-foot radius of the discovery. A qualified professional archaeologist, meeting the Secretary of the Interior’s Professional Qualification Standards for prehistoric and historic archaeology, shall be retained to evaluate the significance of the find, and shall have the authority to modify the nowork radius as appropriate, using professional judgment. The following notifications shall apply, depending on the nature of the find:
 If the professional archaeologist determines that the find does not represent a cultural resource, work may resume immediately and no agency notifications are required.  If the professional archaeologist determines that the find does represent a cultural resource from any time period or cultural affiliation, the archaeologist shall immediately notify the City. The agencies shall consult on a finding of eligibility and implement appropriate treatment measures if the find is determined to be a Historical Resource under CEQA, as defined in Section 15064.5(a) of the CEQA Guidelines, or a Historic Property, as defined in 36 CFR 60.4. Work may not resume within the no-work radius until the City, through consultation as appropriate, determines that the site either: 1) is not a Historical Resource under CEQA or a Historic Property under Section 106 of NHPA, or 2) that the treatment measures have been completed to its satisfaction.  If the find includes human remains, or remains that are potentially human, the professional archaeologist shall ensure reasonable protection measures are taken to protect the discovery from disturbance (AB 2641). The archaeologist shall notify the Riverside County Coroner (per § 7050.5 of the Health and Safety Code). The provisions of § 7050.5 of the California Health and Safety Code, § 5097.98 of the California PRC, and AB 2641 will be implemented. If the Coroner determines the remains are Native American and not the result of a crime scene, the Coroner will notify the NAHC, which then will designate a Native American Most Likely Descendant (MLD) for the project (§ 5097.98 of the PRC). The designated MLD will have 48 hours from the time access to the property is granted to make recommendations concerning treatment of the remains. If the landowner does not agree with the recommendations of the MLD, the NAHC may mediate (§ 5097.94 of the PRC). If no agreement is reached, the landowner must rebury the remains where they will not be further disturbed (§ 5097.98 of the PRC). This will also include either recording the site with the NAHC or the appropriate Information Center; using an open space or conservation zoning designation or easement; or recording a reinternment document with the county in which the property is located (AB 2641). Work may not resume within the no-work radius until the lead Cultural Resources Report for the Kaiser Permanente Riverside Medical Center Expansion Project ECORP Consulting, Inc.

Kaiser Permanente Riverside 26 June 20212020-233
agencies, through consultation as appropriate, determine that the treatment measures have been completed to their satisfaction.

The Lead Agency is responsible for ensuring compliance with these mitigation measures because damage to significant cultural resources is in violation of CEQA and Section 106. Section 15097 of Title 14, Chapter 3, Article 7 of CEQA, Mitigation Monitoring or Reporting, “the public agency shall adopt a program for monitoring or reporting on the revisions which it has required in the project and the measures it has imposed to mitigate or avoid significant environmental effects. A public agency may delegate reporting or monitoring responsibilities to another public agency or to a private entity which accepts the delegation; however, until mitigation measures have been completed the lead agency remains responsible for ensuring that implementation of the mitigation measures occurs in accordance with the program.” Cultural Resources Report for the Kaiser Permanente Riverside Medical Center Expansion Project ECORP Consulting, Inc.
