File #: 23-0556
The proposed multiple family residential project is located within Planning Area 1 of the Dos Lagos Specific Plan. Planning Area 1 is zoned Commercial (“C”), which allows condominiums and apartments with approval of a conditional use permit (CUP), provided the total yield of multi-family residential units within all of Planning Area 1 does not exceed 450.

The project site, which is currently vacant, was part of a larger commercial project approved in 2018 (Precise Plan PP2018-0003), but not completed. PP2018-0003 approved a four-story hotel; a 2,500- square-foot restaurant with drive-through; 15,100 square feet of restaurant and retail space; and a gas station with a convenience store and drive-through car wash. The commercial site plan approved under PP2018-0003 is provided as Exhibit 3. The hotel, gas station, convenience store and drive-through car wash are constructed and operating. The proposed 50-unit residential project is intended to replace the restaurant with drive-through, and the restaurant/retail space, on the west side of Temescal Canyon Road, and on the north and south sides of Fashion Drive.

PROJECT DESCRIPTION
CUP2023-0002 is a site development plan to establish 50 multiple-family residential units within Planning Area 1 of the Dos Lagos Specific Plan. The proposed residential units are being referred to as Terrano Phase II, as they are intended to be a continuation of the existing 276-unit Terrano Apartment project located to the immediate west of the proposed project, which were approved under CUP16-002. Combined, Terrano Phase I and II comprise a total of 326 units, which is less than the maximum number of 450 units the Dos Lagos Specific Plan allows for Planning Area 1.

Site Plan
The project comprises of seven (7) residential buildings designed as either two-story townhomes or three-story stacked flats. The buildings reflect a modern architectural style. Exhibit 4 illustrates the proposed site plan with building placement, parking locations, and recreation amenities. Access to the project is from Fashion Drive, via Temescal Canyon Road and Dos Lagos Drive. Fashion Drive is an existing private street within the development, and it provides access to the other residential and commercial developments within Planning Area 1.

The proposed project is comprised of two areas, which are bisected by Fashion Drive. The north side of Fashion Drive is comprised of 20 attached two-story townhomes, and approximately 4,288 square feet of recreation area. The recreation area consists of a lawn and a pickleball court. The portion south of Fashion Drive is comprised of 10 attached two-story townhomes, 20 stacked flat units within three-story buildings, and approximately 1,270 square feet of recreation area. The recreation consists of two separate lawn areas. The site plan, as designed, meets the minimum building setback requirements from the streets, and the minimum building separation requirements, as prescribed by the Dos Lagos Specific Plan.

All of the two-story townhomes have either a single-car or two-car garage, with direct access from the garage to each unit’s living area. The buildings with the flat units have single-car garages, but there is no direct access from the garages to the units. Covered (carport) parking and uncovered guest spaces are provided within the north and south portions of the project. Table A summarizes the development proposal.

* Parking spaces within Buildings D are assigned at time of lease, which may be in the form of enclosed garage spaces or covered carport spaces.

Parking
The project is required to have 90 covered parking spaces and 10 guest parking spaces, for a total of 100 parking spaces. The project meets this requirement by providing 90 covered parking spaces (57 garages and 33 carport covered spaces), and 22 uncovered guest spaces.

The project’s parking is based on the City standards in effect at the time the applicant initially submitted the project’s preliminary application (Development Plan Review application) to the City, which was August 17, 2022. New parking standards didn’t go into effect until October 2, 2022. The old standards used for this project are:

City of Corona Page 3 of 8 Printed on 7/6/2023
powered by Legistar™
File #: 23-0556
· 1.5 covered parking space per unit, plus 1 uncovered guest space per 5 units · 2 covered parking spaces per unit, plus 1 uncovered guest space per 5 units · 2.5 covered parking spaces per unit, plus 1 uncovered guest space per 5 units The project is allowed to use the older parking standards through a provision under California Senate Bill (SB) 330 (Housing Crisis Act of 2019). Under this bill, a residential project is only subject to the development standards in effect at the time the developer submitted his/her preliminary application (DPR application) to the City. The applicant (Rexco) submitted their formal CUP application on February 13, 2023, 180 days from the DPR submittal, which complies with SB 330 deadlines.

For informational purposes only, if the project had been required to provide parking based on the recently adopted parking standards, the project would have been required to provide 96 covered parking spaces plus 10 guest parking spaces. The difference is that the new standard would require an additional six covered parking spaces more than the old standard.

Architecture
The Dos Lagos Specific Plan’s Architectural Design Guidelines (Guidelines) prescribes an Eclectic Mediterranean theme for development within the Specific Plan area. The Guidelines allow variations to accommodate residential design considerations. The residential buildings proposed for the project have smooth stucco walls, accented with stone veneer, metal railings and built-up flat roof. The architecture includes the use of strong color profiles and textured material to create contrast and visual interest; façade articulations to reduce building massing and volume; and deep recessed entryways to create a pedestrian friendly environment. The contemporary, streamlined exteriors present architectural features and a color scheme similar to the Home2 Suites hotel project to the north, and the Terrano Apartments Phase I project to the west. This results in a unified design style within Planning Area 1. Renderings for the proposed project are attached as Exhibit 6.

Access And Circulation
Access to the project site is provided from Fashion Drive, which connects to Temescal Canyon Road and Dos Lagos Drive. The entrance to the north and south portions of the project are located at the west perimeter of the project site. All internal drive aisles within the project are 24 to 28 feet in width. The main drive aisles are 28 feet in width, as required by the Fire Department. The applicant’s Circulation Plan is attached as Exhibit 7.

The section of Temescal Canyon Road adjacent to the project site is fully improved; therefore, no additional improvement within the right-of-way or widening of the street is required with the project.

Landscaping, Fencing, and Walls
Exhibit 8 illustrates the landscape concept and perimeter fencing for the project. The planting schedule includes California-friendly, low and medium water-use materials. The conceptual landscape plan provides larger tree species adjacent to Temescal Canyon Road, which enhances the residential project. Both sides of Fashion Drive leading into the project’s interior road are lined with shade trees, including evergreen African Sumac, deciduous Red Crape Myrtle, and evergreen Brisbane Box. The interior parking areas are enhanced with deciduous Glendora White Crape Myrtle trees, which have bright colors when in bloom; and deciduous London Plane trees, which are fast-growing. The project City of Corona Page 4 of 8 Printed on 7/6/2023

File #: 23-0556
bright colors when in bloom; and deciduous London Plane trees, which are fast-growing. The project also provides a row of planting hedge in front of carport spaces fronting Temescal Canyon Road, to reduce headlight glare impact.

Perimeter fencing, columns and driveway gates have consistent colors and designs as those existing at the Terrano Phase I project. This includes six-foot high tubular steel fencing, and steel framed driveway gates with seven-foot-high stone veneer pilasters. Pedestrian entries next to the driveway gates have perforated steel mesh for enhanced security.

Both areas on the north and south sides of Fashion Drive will have gated entrances. Per the applicant, the gates will be open during the daytime, and will be closed at night.

Site Amenities and Open Space
The project is required to provide a minimum of 100 square feet of common recreation area per unit, per the Dos Lagos Specific Plan. As proposed, the north portion of the project provides a lawn area and a pickleball court, totaling approximately 4,288-square-foot area. The south portion has approximately 1,270 square feet of open lawn area. In total, the project provides 5,558 square feet of recreation area, which complies with the Specific Plan’s requirement. Furthermore, the applicant has stated that residents of the existing Terrano Phase I and the proposed Terrano Phase II will have reciprocal access to each project’s amenities. The Terrano Phase I project has an on-site fitness center, a half basketball court, a barbeque island adjacent to a swimming pool, and a hot tub.

Each of the proposed residential units are required to have a minimum of 50 square feet of private open space. The proposed project provides open space in the form of uncovered decks accessible from each unit’s great room or living room. Units with a Plan 7 and 8 layout have open space in the form of a patio adjacent to each unit’s entrance.

Sign Program
The submitted site plan shows two entry monument signs at the intersection of Temescal Canyon Road and Fashion Drive. Each monument sign will be flanked by a palm trees. This is similar to the landscaping installed at the Encanto Apartment Homes’ entry signs located across Temescal Canyon Road, to the east of the project. Details of the signs have been provided yet. The sign will be reviewed for compliance with the Dos Lagos Specific Plan sign criteria at the time of permit issuance.

ENVIRONMENTAL ANALYSIS
The City approved the original commercial project (PP2018-0003) and adopted a mitigated negative declaration (MND) for the commercial project on August 20, 2018. Staff has prepared an Addendum to the previously adopted MND for the proposed project, pursuant to Section 15164 of the State CEQA (California Environmental Quality Act) Guidelines. The City, as the lead agency, determined that the proposed project and the Addendum demonstrate that the environmental analysis, impacts, and mitigation requirements identified in the previously adopted MND remain substantively unchanged despite project modifications. The proposed project does not raise any new issues or result in impacts not previously analyzed in the prior MND, and none of the conditions described in Section 15162 of the State CEQA Guidelines requiring the preparation of a subsequent MND exist.

The Addendum is attached as Exhibit 11.

FISCAL IMPACT
The applicant has paid the applicable application processing fees for the project.

PUBLIC NOTICE AND COMMENTS
A 10-day public notice was mailed to all property owners within a 500-foot radius of the project site, as well as advertised in the Sentinel Weekly News, and posted at the project site. As of the preparation of this report, staff has not received any correspondence regarding the proposed project.

STAFF ANALYSIS
CUP2023-0002 is the last undeveloped site within Planning Area 1. Due to change in market conditions, the applicant is proposing to develop 50 multi-family units in place of the approved restaurant and retail uses previous approved for the site under PP2018-0003. Located along both sides of Fashion Drive, the proposed multi-family residential use allows residents to be less car dependent and encourages pedestrian connectivity with recreational amenities and neighborhood serving commercial uses, which are within walking distance. The interior roads within Planning Area 1 provide safe sidewalks and landscaping buffer, creating a friendly village environment that facilitates people movements within Planning Area 1. The design of the proposed project complies with the minimum standards of the Dos Lagos Specific Plan, and is consistent and compatible with existing projects nearby.

The Planning and Development Department recommends approval of CUP2023-0003 based on the following findings of approval and the recommended Conditions of Approval, which are attached as Exhibit 9.

Re: CUP2023-0002 Applicant Letter to construct 50 apartment units May 11 2023
Terrano Plaza, LLC proposes a SO-unit addition to the existing Terrano Apartment project to be located on the North and South sides of Fashion Drive in the commercial designation of the Dos Lagos Specific plan. The Terrano phase 2 development would include (7) residential buildings with unit plans ranging from 600 SF to 1,265 SF. The proposed architectural and landscape design includes 2-story and 3-story buildings with color and design features similar to the first phase of the Terrano project. This project would include site amenities such as a new pickle-ball court and BBQ area. Residents of this phase will have equal access to the amenities at the completed Terrano phase 1 project. The location of Terrano Phase 2 puts it at the heart of the Dos Lagos residential and commercial community, providing its residents with additional amenities at the shops at Dos Lagos, including a gas station to the south, a hotel to the north, and a golf course to the east. This complex provides adequate site access and additional parking above the city's requirements, as well as perimeter fencing to give its residents a more private community experience with a complete range of public amenities nearby.

BACKGROUND & PROJECT DESCRIPTION:

The proposed 50-unit Multiple-Family project, known as Terrano II, is located on the west of Temescal Canyon Road and north of Dos Lagos Drive within Planning Area 1 of the Dos Lagos Specific Plan, in the City of Corona.

Within the Dos Lagos Specific Plan, Planning Area 1 allows a mix of land uses that include commercial, entertainment, office and residential with internal pedestrian connectivity. In June 2016, a 276-unit multiple-family project in 38 apartment buildings, Terrano I, was approved through a Conditional Use Permit review (CUP16-002) and an Initial Study/Mitigated Negative Declaration (IS/MND) was adopted for the project. Terrano I is located along the western edge of Planning Area 1, adjacent to Interstate-15. The eastern edge of the Planning Area 1 fronting Temescal Canyon Road was identified for commercial development. At a public hearing held on August 20, 2018, the commercial component envisioned for the remainder of Planning Area 1 was approved through Precise Plan review (PP2018-0003) and a separate IS/MND was adopted for the commercial project. The entitled commercial development included a 101-room, 4-story hotel; 11,000 square feet of restaurant space including a drive-through; 15,800 square feet of retail floor area including a convenience store with a 10-pump service station and a 2,000-square-foot ancillary drive-through carwash. The Terrano I apartment complex, hotel, and gas station with convenience store and car wash are completed and in operation.

PP2018-0003/CUP2023-0002
IS/MND Addendum July 10, 2023
The proposed Terrano II Multiple Family project consists of replacing the entitled 2,500-square foot drive-through restaurant and 15,100 square feet of restaurant and retail space with 50 multifamily apartment dwelling units in Planning Area 1, located specifically to the north and south sides of Fashion Drive. Figure 1 shows the proposed Terrano II Multiple-Family project location. It is the last development piece to Planning Area 1 of the Dos Lagos Specific Plan, therefore, access for the proposed apartments will be provided via the existing internal circulation system and no new public access driveway are proposed. For the purposes of this Addendum document, the Terrano II Multiple Family project (CUP2023-0002) is the “Modified Project”.

Figure 1:

The purpose of the Addendum is to evaluate the changes that are proposed to the original commercial development entitled under PP2018-0003. In connection with the Addendum, many of the previously approved technical studies have been updated to ensure the Addendum will not result in any environmental impacts not already analyzed in the MND that was previously adopted PP2018-0003/CUP2023-0002
IS/MND Addendum July 10, 2023
for PP2018-0003 or that was not known or could have been known in 2018. These updated studies include a noise assessment, a greenhouse gas assessment, an air quality report, a health risk assessment, and a traffic circulation update. The Addendum results in no additional or increased significant environmental impacts than those discussed in the 2018 MND or could have been discussed in 2018. However, the Addendum will reduce all of the impacts identified in the MND.

Thus, the Addendum is addressed in the Mitigated Negative Declaration, as all impacts of the Addendum are less than those analyzed in the adopted Mitigated Negative Declaration. The proposed modified Project does not result in new or increased significant impacts.

CEQA REQUIREMENTS FOR AN ADDENDUM: (CEQA Guidelines, § 15164(a).) (CEQA Guidelines, § 15162(a).)
As discussed above, the applicant has proposed to develop a 50-unit multi-family residential project to replace the previously entitled retail and restaurant uses within Planning Area 1 of the Dos Lagos Specific Plan. As the proposed residential project (Terrano II) modifies the previously adopted IS/MND, an addendum to the IS/MND is necessary to meet the requirements of the California Environmental Quality Act (CEQA).

The CEQA Guidelines (Sections 15162 and 15164) allow a lead agency t o prepare an addendum to a previously adopted IS/MND if minor technical changes or additions to the environmental evaluation are necessary, but none of the following occurs:

Substantial changes are proposed in the project which will require major revisions to the Environmental Impact Report or negative declaration due to the involvement of new significant effects;

1. Substantial changes occur with respect to the circumstances under which the project is undertaken which will require major revisions of the previous Environmental Impact Report or negative declaration due to involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects; or

2. New information of substantial importance, which was not known and could not have been known with the exercise of reasonable diligence at the time the previous Environmental Impact Report or negative declaration was adopted, shows any of the following:
a. The project will have one or more significant effect not discussed in the Environmental Impact Report;
b. Significant effects previously examined will be substantially more severe than shown;
c. Mitigation measures or alternatives previously found not to be feasible would in fact be feasible, and would substantially reduce one or more significant effects of the project, but the project proponents decline to adopt the mitigation measure or alternative; or
PP2018-0003/CUP2023-0002
IS/MND Addendum July 10, 2023
d. Mitigation measures or alternatives which are considerably different from those analyzed in the previous Environmental Impact Report or negative declaration would substantially reduce one or more significant effects on the environments, but the project proponents decline to adopt the mitigation measure or alternative.

This Addendum documents that included modifications to the approved Project do not trigger any of the conditions described above. Specifically, given the Project description and knowledge of s u p p l e m e n t a l a n a l y s e s c o m p a r i n g t h e proposed project with the previously entitled commercial component of Planning Area 1 that the proposed project intends to replace, the city has concluded that the Modified Project would not result in any new significant impacts not previously disclosed in the circulated IS/MND, nor would it result in a substantial increase in the magnitude of any significant environmental impact previously identified. For these reasons, an addendum to the adopted IS/MND is sufficient to meet the requirements of CEQA.

The Addendum need not be circulated for public review (CEQA Guidelines Section 15164[c]); however, an Addendum must be considered by the decision-making body prior to a decision on the project (CEQA Guidelines Section 15164[d]). This Addendum to the previously adopted IS/MND demonstrates that the environmental analysis, impacts, and mitigation requirements identified in the previously approved Final IS/MND remains substantively unchanged despite minor project refinements described herein and supports the finding that the proposed project does not raise any new issues and does not exceed the level of impacts identified and analyzed in the previously approved Final IS/MND.

The approved mitigation measures provided in the adopted IS/MND Mitigation Monitoring and Reporting Program (MMRP) have been incorporated by reference, with modifications (additions, deletions, renumbering/renaming, or other minor revisions) made as necessary to apply to the modified Project as shown in Appendix A. The adjusted mitigation measures do not change the original impact conclusions from the IS/MND, nor are they considerably different from that analyzed in the IS/MND.

ENVIRONMENTAL CHECKLIST:

CEQA Guidelines 15168(c)(4) recommends using a written checklist or similar device to confirm whether the environmental effects of a subsequent activity were adequately covered in an original project’s IS/MND. The focus of this analysis is on the identified changes associated with the proposed Modified Project (CUP2023-0002) and whether there would be any difference in identified impacts or required mitigation measures from those identified in the previously approved IS/MND.

The following analysis is used to: (1) compare the environmental impacts of the proposed Modified Project with impacts evaluated in the previously adopted IS/MND; (2) to identify whether the proposed Modified Project would result in new or more severe significant environmental impacts; and (3) to identify if there have been substantial changes with respect to the circumstances under which the Modified Project would be undertaken since adoption of the previously approved IS/MND that would result in new or more severe significant environmental effects.

PP2018-0003/CUP2023-0002
IS/MND Addendum July 10, 2023
This analysis confirms that the Modified Project is within the scope of the previously approved IS/MND, and the Modified Project would cause no new or more severe significant effects and no new mitigation measures are required.

The following discussion has been undertaken pursuant to the provisions of CEQA Guidelines Sections 15162 and 15164 to provide the factual basis for determining whether any changes associated with the Proposed Project Modifications, any changes in circumstance, or any new information since adoption of the previously approved IS/MND requires additional environmental review.

Discussion:

The previously adopted IS/MND concluded that the mixed-use commercial project will have no impact related to land use and planning and no mitigation is warranted for this topic.

Proposed Modified Project:

The modified Project will be constructed within Planning Area 1 of the Dos Lagos Specific Plan, which is intended to provide flexibility to market driven development that fosters opportunities for people to live in the same area where neighborhood supportive commercial, entertainment, shopping, and potentially employment are within walking distance reducing the need for vehicle trips. The residential project does not create land use incompatibility as it is consistent with the C (Commercial) zoning and Mixed-Use I General Plan designations. The residential project site is an infill location. It will not divide an established community and is consistent with local land use plans and development standards prescribed in the Dos Lagos Specific Plan. The modified Project will have no impact to land use and planning within Planning Area 1.

The proposed 50 dwelling units will provide rental housing opportunities in addition to the existing Terrano I project which included 276 rental units built in 2017. Overall, at completion of the proposed modified Project, there will be a total of 326 residential rental units available within Planning Area 1 which is below the maximum of 450 units previously evaluated with the master planning of the Dos Lagos area.Therefore, the modified Project will not induce substantial growth.

The modified Project provides additional residential rental units that do not exist presently; therefore,the project will not displace existing residents or remove existing housing units from the market. Therefore, no mitigation is warranted.

Expansive soils
Discussion:

The previous IS/MND disclosed that the project site is not located within an Alquist-Priolo Seismic Special Study Zone, and no known active or potentially active fault crosses the project site. It was also found that the site is not subject to liquefaction because of the soil conditions and combined with the relatively dense nature of the soils. Furthermore, the project site was previously rough graded for commercial development associated with the original project (PP2018-0003). The previous evaluation for the commercial project recognizes the site will need to be further graded in accordance with city’s grading regulation and finished in a manner that achieve positive drainage. Any potential impacts are mitigated by compliance with city’s grading ordinance through the grading permit and inspection process. The proposed modified Project is subject to implementation of an erosion control plan, grading permit 2 Environmental: CUP 2023-0002 Addendum to IS/MND for PP2018-0003 July 10, 2023 requirements and inspection; therefore, it does not cause new or increased significant impacts on geology and soils and no further mitigation is warranted with respect to geologic problems.

Discussion:

The previous IS/MND identified less than significant impact to the water quality standards and waste discharge requirements because the applicant is required to submit a final Water Quality Management Plan (WQMP) for review and approval by the Development Service Division. Additionally, the commercial project was required to implement on-site Best Management Practices (BMPs) identified in the WQMP, install underground stormwater detention and infiltration systems in order to minimize pollutant run-off into the city’s storm water drainage system. The full development entitled for Planning Area 1, both the residential units (Terrano I) and the commercial development were evaluated in a hydrology study and found that the project design at that time would result in less than significant impact provided that the storm water collection and conveyance systems identified in the hydrology study are implemented.

The proposed modified Project is subject to provision of an updated WQMP and hydrology study for review and approval by the Development Service Division. The previously evaluated WQMP accounted for the entirety of construction within Planning Area 1 and was found to be adequate in reducing water quality impacts to less than significant. The proposed modified Project is subject to on-site Best Management Practices and WQMP requirements based on the previous IS/MND which is has a similar or negligible increase of water flow, therefore with the implementation of previously required BMPs, stormwater collection and conveyance systems, the proposed modified Project does not cause new or increased significant impacts on water quality and drainage pattern, and no further mitigation is warranted.

Discussion:

The previous IS/MND provided evaluations of air quality based on based on the worst-case scenario related to trip generation of the mixed-use commercial project. As the proposed modified Project reduces daily trip generation by approximately 50%, as stated in the updated traffic circulation assessment (Linscott, Law & Greenspan, May 10, 2023), the project, at completion would generate far less operational air quality emissions. Measured in pounds per day, the criteria pollutants that are analyzed for operations of the Project include Respirable Particulate Matter (PM10/PM2s), Nitrogen Oxide (NOx), Sulfur Oxide (SOx), Carbon Monoxide (CO), and Reactive Organic Gases (ROG) When compared to the significance thresholds established by the SCAQMO, no pollutant was identified as expected to exceed such thresholds for the daily operational emissions (LDN Consulting, Inc., January 31, 2023, Table 5, Page 6). Likewise, when compared to the significance thresholds established for daily construction air quality emissions, no pollutant will exceed such thresholds (Ibid. Table 4, Page 5). Therefore, no impacts related to air quality emission are anticipated from the proposed modified Project.

Each unit shall be installed with mechanical air quality filtration system with fresh air intake having a minimum efficiency reporting value (MERV) of 13. Such system must be clearly displayed on all plans for plan check and construction.

The developer shall provide written disclosure in the leasing documents for each unit that is located within 300 feet of the existing gasoline station located to the south of the project site regarding the potential health risks to the residents associated with potential exposure to benzene that may be emitted from gasoline refueling operations.

An updated air quality health risk screening letter (LDN Consulting, Inc., January 31, 2023) identify the proposed modified Project’s health risk impacts resulting from exposure to toxic air contaminants (TACs). The project site is located north of Dos Lagos Drive and south of Cabot Drive with the I-15 Freeway located to the west, which is consider a source of pollutant. Generally, risks are stated to be greater for sensitive receptors within 500 feet of a freeway or busy traffic corridor calculated based on a 70-year lifetime exposure and meteorological data. The north portion of the project site is 700 feet from the eastern edge of the I-15 and the south portion is 600 feet from the eastern edge of the I-15. Given the close proximately to the I-15, the applicant stated that all residential units will have mechanical ventilation filtration systems as required by the latest building codes such as California’s Title 24 which required a Minimum Efficiency Reporting Value (MERV) rating of 13. The MERV 13 filtration systems was a mitigation measure for the existing residential component (Terrano I) within Planning Area I, entitled under CUP16-002. Along with written disclosure in the leasing agreement to inform residential of its close proximity to a gasoline station. Given the residential nature of the proposed modified Project and its location within Planning Area 1, the same mitigation measures remain applicable in order to reduce air quality impacts.

Conflict with alternative transportation policies (adopted policies, plans or programs for public transit, bicycle or pedestrian facilities) Discussion:

The previous IS/MND provided mitigation measures that remain applicable to the proposed modified Project as it pertains to the overall access of Planning Area 1. Additionally, updated traffic circulation assessment (Linscott, Law & Greenspan, May 10, 2023) provided a net trip generation comparison between the entitled, unbuilt commercial uses within Planning Area 1 and the proposed 50-unit residential use. The result is a reduction in 2-way daily net trip generation by 68% for the proposed modified Project. The proposed Project will utilize the existing internal circulation system and will not require new public access driveway. With implementation of the previously identified mitigation measures, the proposed modified Project will have no impacts to traffic, and circulation and no additional mitigation measures are warranted.

The table below compares the traffic generation rates and forecast between the proposed 50-unit residential project and the previously entitled commercial component that the proposed project intends to replace.

Discussion:

The previous IS/MND stated that temporary increase in ambient noise level is to be expected during the construction phase. This concern is addressed by strict adherence to city ordinance that regulate construction activities and noise. The prior analysis did not warrant special mitigation beyond city ordinance to prevent noise impacts.

A noise assessment for the proposed modified Project (LDN Consulting, Inc., January 31, 2023) found that city ordinance in regulating construction hours remain effective in preventing potential noise impact. The assessment also recommended that all equipment should be properly fitted with mufflers and all staging and maintenance should be conducted as far away from the existing residence as possible.

Construction vibrations impacting existing residential uses to the west (Terrano I) are found to be less than the Federal Transit Administration criteria for nuisance for nearby residential uses, therefore the assessment found the potential vibration impact o be less than significant. The assessment also recommended that the architectural plans to be designed to reduce interior noise to 45 dBA CNEL (Community Noise Exposure Level). These specific measures will be confirmed with the construction documents and during the plan check review process, prior to issuance of building permit. Therefore, the proposed modified Project will not result in any new or increased significant noise impacts.

Discussion:

The previous IS/MND for the commercial development did not consider the additional student enrollment in the Corona Norco Unified School District. As such the proposed modified Project has the potential to increase school enrollment not previously evaluated. The added 6 Environmental: CUP 2023-0002 Addendum to IS/MND for PP2018-0003 July 10, 2023 residential units is subject to payment of statutory school fees at the time of building permit issuance.

As the proposed modified Project and the implemented Terrano I project yield a total of 326 dwelling units, Planning Area 1 remains below the 450 residential units ascribed in the Specific Plan. The addition of 50 dwelling units does not change the demand for services that warrant the construction of additional fire facilities, police facilities, schools, or other similar facilities. To offset the cost of public services, the developer is required to applicable development impact fees at the time of issuance of building permits for the project. Therefore, no further mitigation is warranted.

The proposed modified Project increases the residential units within Planning Area 1 but Planning Area 1 will remain below the 450 units prescribed by the Specific Plan which is within the growth parameters of the city’s 2020-2024 General Plan. The developer is responsible for coordinating with utilities providers to provide service to the new residential units. Therefore, the proposed modified Project poses no new impact or increased impacts on public services or utilities and no mitigation measures are warranted. 13 AESTHETICS: Potentially

The project site is not considered a scenic vista per the City’s Environmental Resources Element of the General Plan, therefore development of the project site will not impact scenic vista.

The previous IS/MND evaluated a commercial design with retail and restaurant uses at the project site. The proposed modified Project is residential and adhere to design guidelines established for High Density Residential development, along with landscaping requirements for the site. The proposed site layout and exterior building design, including finishes treatments are similar to the existing residential project to the west (Terrano I) and the hotel to the immediate north. The proposed modified Project provides a sense of cohesiveness with existing development within Planning Area 1 and enhances the aesthetic along Temescal Canyon Road. The proposed modified Project will not result in impacts related to aesthetics and light pollution. Therefore, no mitigation is warranted. 7 Environmental: CUP 2023-0002 Addendum to IS/MND for PP2018-0003 July 10, 2023

Discussion:

The previous IS/MND reference a prior study related to Cultural Resources for the entire Dos Lagos Specific Plan area and concluded that the subject site has low potential for prehistoric or historic archaeological resources. The site was historically excavated and filled up to 14 feet and re-compacted in anticipation of future development However, the study still prescribes that if unanticipated cultural materials are unearthed during construction, work should be halted in the area until a qualified archaeologist can assess the significance of the find.

In accordance with standard mitigation required for the protection of cultural resources and in keeping with applicable laws, if human remains are encountered, State Health and Safety Code Section 7050.5 states that no further disturbance shall occur until the County Coroner has made a determination of origin and disposition pursuant to PRC Section 5097.98. Therefore, to ensure the preservation of any potential cultural or Paleontological resources, mitigation is warranted to ensure the project will have a less than significant effect on the environment with respect to cultural resources. The existing mitigation measures in the previously adopted MND for the original project remain applicable to the proposed modified Project.

Discussion:

The previous IS/MND did not identify negative impacts to fish or wildlife as the as the site contains no bodies of water or known wildlife habitat. The site is the remaining vacant areas (comprising of 2.96 acres) within Planning Area 1 and was previously rough graded with existing commercial development on the adjacent property to the north and major street frontage on three frontages including Interstate 15 along the west site boundary. There is no evidence before the city that the project will have an adverse effect on fish or wildlife resources or cumulatively considerable impacts.

The proposed modified Project will not cause any additional mandatory findings of significance. The significance conclusions under the proposed modified Project are the same as the previous IS/MND because the additional 50 dwelling units will not cause any new or increased significant impacts and in fact, will result in decreased impacts in many categories such as traffic, noise, and greenhouse gas emissions.

19. PREVIOUS ENVIRONMENTAL ANALYSIS:

Earlier analysis may be used when one or more of the environmental effects have been adequately analyzed in an earlier EIR or Negative Declaration (Section 15063).

One or more portions of this Initial Study may have relied upon previous analysis in the IS/MND prepared for PP2018-0003 and CUP2018-0007 adopted on August 20, 2018, containing pertinent evaluation related to the subject project site.

Subject: Traffic Circulation Assessment for the Proposed Terrano II Apartments at Dos Lagos Project
Corona, California
Dear Mr. Tritz:

Linscott, Law & Greenspan, Engineers (LLG) is pleased to submit the following Traffic Impact Assessment for the proposed Terrano II Apartments at Dos Lagos Project to replace the current entitlement on this portion of Planning Area 1 of Dos Lagos in the City of Corona, California. This analysis evaluates the potential traffic circulation impacts associated with the proposed multifamily residential replacement Project consistent with City of Corona requirements based on the City of Corona Traffic Impact Study Guidelines, (June 2006). It should be noted that this trip generation comparison analysis is based on the approved Traffic Impact Analysis (TIA) report for Planning Area 1 Terrano at Dos Lagos, prepared by LLG (May 21, 2018) and attached for reference.

PROJECT LOCATION AND DESCRIPTION
Planning Area 1 of the Dos Lagos Specific Plan was entitled in 2018 and included a 276-unit apartment complex, a 107 room hotel, 6,100 square-feet (SF) of commercial uses, 10,300 SF of restaurant uses (4,000 SF quality restaurant use and 6,300 SF high-turnover sit-down restaurant use), and a 20-fueling position gas station with convenience store and car wash, of which the apartment complex, hotel, and gas station are completed and opened. Figure 1 presents the proposed site plan for the Project, prepared by Summa Architecture, which shows the proposed apartment development and existing Planning Area 1 development. As shown in Figure 1, the proposed Project consists of replacing the entitled retail and restaurant uses with 50 multifamily (low-rise) apartment dwelling units within eight (8) buildings. Access for the proposed apartments will be provided via the existing internal circulation system and no new public access driveway are proposed.

PROJECT TRAFFIC CHARACTERISTICS
Trip Generation Forecast Comparison
Traffic generation is expressed in vehicle trip ends, defined as one-way vehicular movements, either entering or exiting the generating land use. Generation equations and/or rates used in the traffic forecasting procedure are found in the Eleventh Edition of Trip Generation, published by the Institute of Transportation Engineers (ITE) [Washington D.C., 2021].

Table 1, attached, summarizes the trip generation rates used in forecasting the vehicular trips generated for the proposed Project and entitled land use and also presents the proposed Project’s net forecast peak hour and daily traffic volumes. As shown in the upper portion of Table 1, the trip generation potential of the proposed Project was estimated using the using ITE Land Use 220: Multifamily Housing (LowRise) Not Close to Rail Transit trip rates whereas the entitled retail and restaurant uses trip generation is based on the trip generation forecast (Tables 5-1 and 5-2) contained in the approved LLG TIA (May 21, 2018) on Pages 13 and 14.. Review of the middle of Table 1 indicates that the proposed apartment Project is forecast to generate 337 daily trips, with 20 trips (5 inbound, 15 outbound) produced in the AM peak hour and 26 trips (16 inbound, 10 outbound) produced in the PM peak hour on a “typical” weekday.

Next, review of the following section of Table 1 indicates that the entitled 6,100 square-feet (SF) of commercial uses and 10,300 SF of restaurant uses (4,000 SF quality restaurant use and 6,300 SF high-turnover sit-down restaurant use) is forecast to generate 1,075 daily trips, with 63 trips 31 inbound, 32 outbound) produced in the AM peak hour and 63 trips (39 inbound, 24 outbound) produced in the PM peak hour on a “typical” weekday.

As shown on the last row of Table 1, the net trip generation potential of the proposed Project compared to the trip generation of the entitled retail and restaurant uses is 738 net fewer daily trips, with 43 net fewer trips (-26 inbound, -17 outbound) produced in the AM peak hour and 37 net fewer trips (-23 inbound, -14 outbound) produced in the PM peak hour on a “typical” weekday.

As a result, based on the negative net trip generation forecast for the proposed Project compared to the entitled uses for Planning Area 1 of the Dos Lagos development, the proposed Project will not significantly impact the surrounding transportation system and does not require the preparation of a traffic impact study including level of service.

CONCLUSION
Based on the results of the aforementioned net project trip generation forecast for the proposed Terrano II Apartments at Dos Lagos Project, which is 738 net fewer daily trips, with 43 net fewer trips (-26 inbound, -17 outbound) produced in the AM peak hour and 37 net fewer trips (-23 inbound, -14 outbound) produced in the PM peak hour on a “typical” weekday, we conclude that the proposed Project’s traffic circulation impact is considered “insignificant” based on the City of Corona TIS Guidelines.

Therefore, the Project would not require any specific traffic analysis including level of service.

Existing With Project Traffic Conditions
 For the Existing With Project traffic conditions, all ten (10) key study intersections are forecast to operate at acceptable levels of service (LOS D or better) during the AM and PM peak hours when compared to the LOS standards defined in this report.

Year 2020 With Project Traffic Conditions
 For the Year 2020 With Project traffic conditions, one (1) of the ten key study intersections (Temescal Canyon Road at Cajalco Road) is forecast to operate at an unacceptable level of service during the PM peak hour when compared to the LOS standards defined in this report, and will be significantly impacted for the Year 2020 With Project traffic conditions.

However, the implementation of the recommended improvements will offset the Project impacts and return the operating condition of the intersection to an acceptable level of service. The remaining key study intersections are projected to operate at acceptable service.  The following improvements listed below have been identified to mitigate the traffic impacts at the intersection impacted by Project traffic:
o Temescal Canyon Road at Cajalco Road: Restripe the northbound approach to provide a third exclusive northbound left-turn lane and restripe the shared northbound through/right-turn lane to an exclusive northbound right-turn lane. Install eastbound right-turn overlap traffic signal phasing that will yield to northbound U-turn movements.
 The Project’s fair share responsibility toward the restriping the northbound approach and the installation of an eastbound right-turn overlap is 30.36%. As the total cost of the improvements is estimated to be $20,000, the Project’s fair share contribution is approximately $6,072.00.
 The Project driveways are forecast to operate at acceptable levels of service during the AM and PM peak hours under the Year 2020 With Project traffic conditions.  The on-site circulation was evaluated in terms of vehicle-pedestrian conflicts. Based on our review of the preliminary site plan, the overall layout does not create significant vehiclepedestrian conflict points such that access for the residential and commercial components are not impacted by internal vehicle queuing/stacking. Project traffic is not anticipated to cause significant internal queuing/ stacking at the Project driveway. The on-site circulation is acceptable based on our review of the proposed site plan. The alignment and spacing of the Project driveway is also deemed adequate. Turning movements into and out of the Project site at the Project driveway are anticipated to operate at an acceptable service levels. As such, motorists entering and exiting the Project site from this driveway will be able to do so comfortably, safely, and without undue congestion.

PLANNING AREA 1

TERRANO AT DOS LAGOS
Corona, California
May 21, 2018
(Update of Report dated December 29, 2017)

1.0 INTRODUCTION
This traffic impact analysis evaluates the potential traffic impacts of the proposed Planning Area 1 Terrano at Dos Lagos project (hereinafter referred to as Project), on the area traffic circulation. The proposed Project consists of developing a 276-unit apartment complex, a 107 room hotel, 6,100 square-feet (SF) of commercial uses, 10,300 SF of restaurant uses, and a 20-fueling position gas station with convenience store and car wash. The Project site is located on the northwest quadrant of Temescal Canyon Road and Dos Lagos Drive, in the southeast area of the City of Corona, California. Project access will be provided via three (3) driveways along Temescal Canyon Road and one (1) driveway along Dos Lagos Drive. The Project is anticipated to be completed and fully occupied by Year 2020.

This report documents the findings and recommendations of a traffic impact analysis conducted by Linscott, Law & Greenspan, Engineers (LLG) to determine the potential impacts the Project may have on the local network in the vicinity of the Project site. The traffic impact analysis evaluates the operating conditions at ten (10) existing key study intersections and four (4) proposed Project driveways within the Project vicinity, estimates the trip generation potential of the Project and forecasts future (near-term) operating conditions without and with the Project.

The Project site has been visited and an inventory of adjacent area roadways and intersections was performed. Existing (i.e. baseline) peak hour traffic information has been collected at the ten (10) key study intersections on a “typical” weekday for use in the preparation of intersection level of service calculations. This traffic report analyzes existing (i.e. baseline) and future (near-term) weekday AM and PM peak hour traffic conditions for Existing (i.e. baseline) and Year 2020 traffic conditions without and with the proposed Project. Peak hour traffic forecasts for the Year 2020 traffic conditions have been projected by increasing existing traffic volumes by an annual growth rate of two percent (2%) per year and adding the traffic from nine (9) cumulative projects.

The work program for this traffic study was developed in conjunction with the City of Corona Public Works Department staff. Appendix A contains a copy of the approved City of Corona Traffic Impact Study Scoping Agreement.

 This route does not traverse any of study intersections analyzed in this report during weekdays, but the Red Line provides service to The Promenade Shops at Dos Lagos on Saturdays via Temescal Canyon Road from the north.

3.3 Existing Area Traffic Volumes
Existing AM and PM peak hour traffic volumes for the ten (10) key study intersections evaluated in this report, were collected by Counts Unlimited, Inc. in October 2017. Appendix C contains the existing intersection turning movement traffic count data.

Figures 3-3 and 3-4 present the existing AM and PM peak hour traffic volumes, respectively, for the ten (10) existing key study intersections.

3.4 Level Of Service (LOS) Analysis Methodologies
AM and PM peak hour operating conditions for the key study intersections were evaluated using the methodology outlined in Chapter 19 of the Highway Capacity Manual 6 (HCM 6) for signalized intersections and the methodology outlined in Chapter 20 of the HCM 6 for two-way stop-controlled intersections.

3.4.1 Highway Capacity Manual (HCM) Method of Analysis (Signalized Intersections) In conformance with City of Corona requirements, AM and PM peak hour operating conditions for the key study intersections were evaluated using the HCM operations method of analysis. Based on the HCM operations method of analysis, level of service for signalized intersections and approaches is defined in terms of control delay, which is a measure of the increase in travel time due to traffic signal control, driver discomfort, and fuel consumption. Control delay includes the delay associated with vehicles slowing in advance of an intersection, the time spent stopped on an intersection approach, the time spent as vehicles move up in the queue, and the time needed for vehicles to accelerate to their desired speed. LOS criteria for traffic signals are stated in terms of the control delay in seconds per vehicle. The LOS thresholds established for the automobile mode at a signalized intersection are shown in Table 3-1.

N:\3200\2123291 - Rexco Dos Lagos, Corona\Planning Area 1 - Terrano\Report\3291 - Planning Area 1 - Terrano at Dos Lagos, Corona TIA 05-21-18.doc 7 3.4.2 Highway Capacity Manual (HCM) Method of Analysis (Unsignalized Intersections) The HCM unsignalized methodology for stop-controlled intersections was utilized for the analysis of the unsignalized intersections. LOS criteria for unsignalized intersections differ from LOS criteria for signalized intersections as signalized intersections are designed for heavier traffic and therefore a greater delay. Unsignalized intersections are also associated with more uncertainty for users, as delays are less predictable, which can reduce users’ delay tolerance.

Two-way stop-controlled intersections are comprised of a major street, which is uncontrolled, and a minor street, which is controlled by stop signs. Level of service for a two-way stop-controlled intersection is determined by the computed or measured control delay. The control delay by movement, by approach, and for the intersection as a whole is estimated by the computed capacity for each movement. LOS is determined for each minor-street movement (or shared movement) as well as major-street left turns. The worst side street approach delay is reported. LOS is not defined for the intersection as a whole or for major-street approaches, as it is assumed that major-street through vehicles experience zero delay. The HCM control delay value range for two-way stopcontrolled intersections is shown in Table 3-2.

3.5 Impact Criteria and Thresholds

3.5.1 Intersections
The City of Corona considers LOS D to be the minimum acceptable LOS for all intersections that consist of collector and arterial roadways and LOS E for the Weirick Road at I-15 Ramp intersections based on the City of Corona General Plan Circulation Element Policy 6.1.6. In addition, the City of Corona considers LOS C to be the minimum acceptable LOS for local and collector streets in residential and industrial areas.

The City of Corona General Plan Circulation Element Policy 6.1.6 (adopted March 17, 2004) states:
 Maintain Level of Service D or better on arterial streets wherever possible. At some key locations, such as at heavily traveled freeway interchanges, LOS E may be adopted as the acceptable standard, on a case-by-case basis. Locations that may warrant the LOS E standard include Lincoln Avenue at SR-91, Main Street at SR-91, McKinley Avenue at SR-91, Hidden Valley Parkway at I-15, Cajalco Road at I-15 and Weirick Road at I-15. A higher standard such as Level of Service C or better may be adopted for local and collector streets in residential areas.

LEVEL OF SERVICE CRITERIA FOR SIGNALIZED INTERSECTIONS (HCM METHODOLOGY) 1 Level of Service
(LOS)
Control Delay Per Vehicle
(seconds/vehicle) Level of Service Description
A < 10.0
This level of service occurs when progression is
extremely favorable and most vehicles arrive during the green phase. Most vehicles do not stop at all. Short cycle lengths may also contribute to low delay.

B > 10.0 and < 20.0
This level generally occurs with good progression, short cycle lengths, or both. More vehicles stop than with LOS A, causing higher levels of average delay.

C > 20.0 and < 35.0
Average traffic delays. These higher delays may result
from fair progression, longer cycle lengths, or both.

Individual cycle failures may begin to appear at this level.

The number of vehicles stopping is significant at this
level, though many still pass through the intersection
without stopping.

D > 35.0 and < 55.0
Long traffic delays At level D, the influence of
congestion becomes more noticeable. Longer delays may
result from some combination of unfavorable progression, long cycle lengths, or high v/c ratios. Many vehicles stop and the proportion of vehicles not stopping declines.

Individual cycle failures are noticeable.

E > 55.0 and < 80.0
Very long traffic delays This level is considered by many agencies to be the limit of acceptable delay. These high delay values generally indicate poor progression, long
cycle lengths and high v/c ratios. Individual cycle failures are frequent occurrences.

F  80.0
Severe congestion This level, considered to be
unacceptable to most drivers, often occurs with over
saturation, that is, when arrival flow rates exceed the capacity of the intersection. It may also occur at high v/c ratios below 1.0 with many individual cycle failures. Poor progression and long cycle lengths may also be major
contributing factors to such delay levels.

In order to estimate the traffic impact characteristics of the Project, a multi-step process has been utilized. The first step is traffic generation, which estimates the total arriving and departing traffic on a peak hour and daily basis. The traffic generation potential is forecast by applying the appropriate vehicle trip generation equations and/or rates to the Project development tabulation.

The second step of the forecasting process is traffic distribution, which identifies the origins and destinations of inbound and outbound Project traffic. These origins and destinations are typically based on demographics and existing/expected future travel patterns in the study area.

The third step is traffic assignment, which involves the allocation of Project traffic to study area streets and intersections. Traffic assignment is typically based on minimization of travel time, which may or may not involve the shortest route, depending on prevailing operating conditions and travel speeds.

Traffic distribution patterns are indicated by general percentage orientation, while traffic assignment allocates specific volume forecasts to individual roadway segments and intersection turning movements throughout the study area.

With the forecasting process complete and Project traffic assignments developed, the impact of the Project is isolated by comparing operational (LOS) conditions at selected key intersections using expected future traffic volumes with and without forecast Project traffic. If necessary, the need for site-specific and/or cumulative local area traffic improvements can then be evaluated.

5.1 Project Trip Generation Forecast
Traffic generation is expressed in vehicle trip ends, defined as one-way vehicular movements, either entering or exiting the generating land use. Generation equations and/or rates used in the traffic forecasting procedure are found in the Ninth Edition of Trip Generation, published by the Institute of Transportation Engineers (ITE) [Washington D.C., 2012].

Table 5-1 summarizes the trip generation rates used in forecasting the vehicular trips generated by the proposed Project. The trip generation potential for the proposed Project was forecast using the ITE Land Use rates shown in Table 5-1.

Table 5-2 presents the forecast daily and peak hour Project traffic volumes for a "typical" weekday.

Applicable pass-by reduction and internal capture factors were incorporated into the daily, AM peak hour and PM peak hour traffic forecasts. The factors used in this report, which are summarized in the footnotes of Table 5-2, are based on information published in the Trip Generation Handbook, published by ITE, August 2014.

Hence, the net traffic generation potential of the proposed project totals 4,775 daily trips (one half arriving, one half departing), with 329 trips (134 inbound, 195 outbound) produced in the AM peak hour and 326 trips (192 inbound, 134 outbound) produced in the PM peak hour. The potential traffic impacts of the aforementioned net project trips are evaluated in the traffic analysis section of this report. The trip generation methodology and forecasts were approved by the City of Corona staff prior to proceeding with further analysis.

5.2 Project Trip Distribution and Assignment
The directional trip distribution patterns for the Residential and Commercial components of the Project are presented in Figures 5-1 and 5-2. Project traffic volumes, both entering and exiting the site, have been distributed and assigned to the adjacent street system based on the following considerations:
 the site's proximity to major traffic carriers (i.e. I-15 Freeway, Cajalco Road, etc…),  expected localized traffic flow patterns based on adjacent street channelization and presence of traffic signals;
 ingress/egress availability at the Project site; and
 the traffic-carrying capacity and travel speed available on roadways serving the Project site.

The Project trip distribution pattern was submitted to the City staff for their review and approval prior to proceeding with further analyses.

The anticipated AM and PM peak hour Project traffic volumes at the ten (10) key study intersections and four (4) Project driveways are presented in Figures 5-3 and 5-4, respectively. The traffic volume LINSCOTT, LAW & GREENSPAN, engineers LLG Ref. 2-12-3291-1 Planning Area 1 – Terrano at Dos Lagos, Corona

6.1 Existing With Project Traffic Volumes
The estimates of Project-generated traffic volumes were added to the Existing traffic conditions to develop traffic projections for the Existing With Project traffic conditions. Figures 6-1 and 6-2 present the anticipated AM and PM peak hour Existing With Project traffic volumes, respectively, at the ten (10) key study intersections and four (4) Project driveways.

6.2 Year 2020 Without Project Traffic Volumes

6.2.1 Ambient Growth Traffic
For future traffic conditions, background traffic growth estimates have been calculated using an ambient growth factor. The ambient growth factor is intended to include unknown and future cumulative projects in the study area, as well as account for regular growth in traffic volumes due to the development of projects outside the study area. The application of the two percent (2%) annual growth rate to baseline Year 2017 traffic volumes results in a six percent (6%) growth in existing baseline volumes at the ten (10) key study intersections to horizon Year 2020.

6.2.2 Cumulative Projects Traffic
The City of Corona and Riverside County have identified nine (9) cumulative projects within the Project study area. Cumulative projects, as defined by Section 15355 of the CEQA Guidelines, are “closely related past, present and reasonably foreseeable probable future projects.” The Traffic Impact Analysis assumes that these cumulative projects will be developed and operational when the proposed Project is operational, which is the most conservative approach, since the exact timing of each cumulative project is uncertain. In addition, impacts for these cumulative projects would likely be, or have been, subject to mitigation measures, which could reduce potential impacts. Under this analysis, however, those mitigation measures are not considered. The locations of these cumulative projects are presented in Figure 6-3.

Table 6-1 presents the location, description, and development totals of the cumulative projects.

Table 6-2 presents the resultant trip generation for cumulative projects. As shown in Table 6-2, the nine (9) cumulative projects are expected to generate 9,222 daily trips (one half arriving, one half departing) on a “typical” weekday, with 768 trips forecast during the AM peak hour and 913 trips forecast during the PM peak hour.

The anticipated AM and PM peak hour cumulative projects traffic volumes at the ten (10) key study intersections are presented in Figures 6-4 and 6-5, respectively. Figures 6-6 and 6-7 present Year 2020 Without Project AM and PM peak hour traffic volumes at the ten (10) key study intersections, respectively. It should be noted that Year 2020 Without Project traffic volumes include ambient traffic growth as well as the traffic from the nine (9) cumulative projects.

It should be emphasized that because this traffic impact analysis utilizes both an ambient growth factor along with a list of cumulative projects approach to analyze cumulative impacts, this traffic impact analysis is conservative and would tend to overstate cumulative traffic impacts.

The existing conditions analysis establishes the basis for the future forecasts for the Project. This analysis is based on existing intersection counts collected in October 2017. The existing conditions analysis reflects these counts as well as existing lane configurations for all analyzed intersections.

7.1 Existing Conditions Intersection Capacity Analysis
Table 7-1 summarizes the peak hour Level of Service results at the key study intersections for existing traffic conditions, with and without the Project. The first column (1) of Delay/LOS values in Table 7-1 presents a summary of Existing AM and PM peak hour traffic conditions. The second column (2) in Table 7-1 presents forecast Existing With Project traffic conditions. The third column (3) of Table 7-1 shows whether the traffic associated with the Project will have a significant impact based on the LOS standards and the significance impact criteria defined in this report. The fourth column (4) of Table 7-1 presents the Level of Service with the implementation of traffic mitigation improvements, if necessary.

7.1.1 Existing Traffic Conditions
Review of column (1) of Table 7-1 indicates that for the Existing traffic conditions, all ten (10) existing key study intersections currently operate at acceptable levels of service (LOS D or better) during the AM and PM peak hours when compared to the LOS standards defined in this report.

7.1.2 Existing With Project Traffic Conditions
Review of column (2) of Table 7-1 indicates that for the Existing With Project traffic conditions, all ten (10) key study intersections are forecast to operate at acceptable levels of service (LOS D or better) during the AM and PM peak hours when compared to the LOS standards defined in this report.

Review of column (3) of Table 7-1 indicates that none of the ten (10) key study intersections will be significantly impacted based on the LOS criteria defined in this report for the Existing With Project traffic conditions.

Appendix D contains the Delay/LOS calculation worksheets for the Existing Traffic Conditions.

The relative impacts of the added Project traffic volumes generated by proposed Project during the AM and PM peak hour conditions was evaluated based on analysis of future Year 2020 operating conditions at the ten (10) key study intersections, with and without the proposed Project. The previously discussed capacity analysis procedures were utilized to investigate the future Delay and service level characteristics at each study intersection. The significance of the potential impacts of the Project at each key intersection was then evaluated using the traffic impact criteria mentioned in this report.

8.1 Year 2020 Conditions Intersection Capacity Analysis Table 8-1 summarizes the AM and PM peak hour Level of Service results at the key study intersections for the Year 2020 traffic conditions. The first column (1) of Delay/LOS values in Table 8-1 presents a summary of existing AM and PM peak hour traffic conditions (which were also presented in Table 7-1). The second column (2) presents forecast Year 2020 Without Project traffic conditions and the third column (3) identifies forecast Year 2020 With Project traffic conditions. The fourth column (4) indicates whether the traffic associated with the Project will have a significant impact based on the significant impact criteria mentioned in this report. The fifth column (5) presents the resultant level of service with the inclusion of recommended traffic improvements, where needed, to achieve an acceptable level of service.

8.1.1 Year 2020 Without Project Traffic Conditions
Review of column (2) of Table 8-1 indicates that for the Year 2020 Without Project traffic conditions, one (1) of the ten (10) key study intersections is forecast to operate at an unacceptable level of service during the AM and PM peak hours when compared to the LOS standards defined in this report. This intersection, reported below, is forecast to continue to operate at an adverse level of service during the peak hours indicated:

For those intersections where projected traffic volumes are expected to result in unacceptable operating conditions, this report recommends improvement measures that change the intersection geometry to increase capacity. These capacity improvements may involve roadway widening and/or re-striping to reconfigure specific approaches of a key intersection. The identified improvements are expected to:
 mitigate the impact of existing traffic, Project traffic and future non-Project (ambient traffic growth and cumulative projects) traffic and
 improve Levels of Service to an acceptable range and/or to pre-Project conditions.

9.1 Existing With Project Traffic Conditions
The results of the Existing With Project intersection capacity analysis presented previously in Table 7-1 indicate that the proposed Project will not impact any of the key study intersections. As such, no improvements are recommended for the Existing With Project traffic conditions.

9.2 Year 2020 With Project Traffic Conditions
The results of the Year 2020 With Project intersection capacity analysis presented previously in Table 8-1 indicate that the proposed Project will impact one (1) of the key study intersections. The following improvements listed below have been identified to mitigate the traffic impacts at the intersection impacted by Project traffic:
 Temescal Canyon Road at Cajalco Road: Restripe the northbound approach to provide a third exclusive northbound left-turn lane and restripe the shared northbound through/right-turn lane to an exclusive northbound right-turn lane. Install eastbound right-turn overlap traffic signal phasing that will yield to northbound U-turn movements.

Figure 9-1 presents the recommended improvements at the key study intersections for the Year 2020 With Project traffic conditions.

The transportation impacts associated with the development of the proposed Project were determined based on the future conditions analysis with and without the proposed Project. The key study locations forecast to operate at adverse levels of service are discussed below. As such, the proposed Project’s “fair-share” of the recommended traffic improvements has been calculated for the key study locations that are forecast to operate at adverse levels of service in the Year 2020 traffic conditions.

10.1 Existing With Project Traffic Conditions
None of the ten (10) key study intersections are forecast to have a significant impact under Existing With Project traffic conditions when compared to the LOS criteria defined in this report. Thus, no mitigation measures are necessary.

10.2 Year 2020 With Project Traffic Conditions
Table 10-1 presents the AM and PM peak hour Project fair share percentage at the key study intersections that are forecast to operate at adverse levels of service in the Year 2020 With Project traffic conditions. As presented in Table 10-1, the first column (1) presents the increase in intersection delay due to Project traffic only. The second column (2) presents the total intersection delay of the intersection. The third column (3) presents the acceptable LOS delay as defined in Chapter 19 of the Highway Capacity Manual 6. The fourth column (4) represents the Project’s fair share based on the following formula:
 Project Fair Share (4) = Column (1)/[Column (2) – Column (3)]*100 The fifth column (5) presents the total estimated improvement cost for the recommended improvements. The sixth column (6) presents the Project’s fair share contribution, based on the fair share percentage and the total estimated improvement cost.

The Project fair share percentage (worse time period impacted) for the impacted intersection for the Year 2020 With Project traffic conditions is shown below:
 Temescal Canyon Road at Cajalco Road 30.36%
As shown in Table 10-1, the Project’s fair share responsibility toward the restriping the northbound approach and the installation of an eastbound right-turn overlap is 30.36%. As the total cost of the improvements is estimated to be $20,000, the Project’s fair share contribution is approximately $6,072.00.

11.1 Site Access
As previously detailed, Project access will be provided via three (3) driveways along Temescal Canyon Road and one (1) driveway along Dos Lagos Drive. Driveways 1 and 3 (located along Temescal Canyon Road) and Driveway 4 (located along Dos Lagos Road) will be stop-controlled right-in/right-out only driveways, while Driveway 2 (located along Temescal Canyon Road) will be a signalized (six-phase) full movement driveway.

11.1.1 Year 2020 With Project Traffic Conditions
Table 11-1 summarizes the levels of service at the Project driveways for Year 2020 With Project traffic conditions. The operations analysis for the Project access is based on the Highway Capacity Manual 6 (HCM 6) Method of Analysis for unsignalized intersections. As shown in column (1) of Table 11-1 the Project access is forecast to operate at acceptable levels of service during the AM and PM peak hours under the Year 2020 With Project traffic conditions. Appendix F contains the Delay/LOS calculation worksheets for the Year 2020 With Project Traffic Conditions.

11.2 Internal Circulation
The on-site circulation was evaluated in terms of vehicle-pedestrian conflicts. Based on our review of the preliminary site plan, the overall layout does not create significant vehicle-pedestrian conflict points such that access for the residential and commercial components are not impacted by internal vehicle queuing/stacking. Project traffic is not anticipated to cause significant internal queuing/ stacking at the Project driveway. The on-site circulation is acceptable based on our review of the proposed site plan. The alignment and spacing of the Project driveway is also deemed adequate.

Turning movements into and out of the Project site at the Project driveway are anticipated to operate at an acceptable service levels. As such, motorists entering and exiting the Project site from this driveway will be able to do so comfortably, safely, and without undue congestion.

To address City staff concerns regarding left-turn and right-turn stacking/storage lengths at several locations, a queuing evaluation was prepared for the following movements:
 Temescal Canyon Road at Project Driveway 1
o Eastbound Right-turn
 Temescal Canyon Road at Project Driveway 2
o Northbound Left-turn
o Southbound Right-turn
o Eastbound Left-turn
 Project Driveway 4 at Dos Lagos Drive
o Southbound Right-turn
Table 12-1 identifies the minimum required stacking/storage lengths for affected left-turn and rightturn lanes for the Project driveways for the Existing With Project and Year 2020 With Project traffic conditions. Column (1) shows the existing or proposed storage length, in feet. Column (2) shows the left-turn or right-turn queue (in vehicles per lane), the corresponding required storage necessary to accommodate the vehicles (in feet, assuming 25 feet per vehicle), and indicates whether or not the existing storage is sufficient based on the calculated 95th percentile queue for Existing With Project traffic conditions. Column (3) shows the left-turn or right-turn queue (in vehicles per lane), the corresponding required storage necessary to accommodate the vehicles (in feet, assuming 25 feet per vehicle), and indicates whether or not the existing storage is sufficient based on the calculated 95th percentile queue, for Year 2020 With Project traffic conditions.

12.1 Existing With Project Intersection Queuing Evaluation As presented in Column (2) of Table 12-1 under Existing With Project traffic conditions, all existing or proposed left-turn or right-turn storage is sufficient at the Project driveways along Temescal Canyon Road and Dos Lagos Drive.

12.2 Year 2020 With Project Intersection Queuing Evaluation As presented in Column (3) of Table 12-1 under Year 2020 With Project traffic conditions, all existing or proposed left-turn or right-turn storage is sufficient at the Project driveways along Temescal Canyon Road and Dos Lagos Drive.

RE: Terrano II Multi-Family Development at Dos Lagos Air Quality – City of Corona The purpose of this air quality screening letter is to identify air quality impacts, if any, which may be created from the construction and operation of the proposed 50-unit Apartment complex on a 2.96 acre project site within Planning Area 1 of the Dos Lagos Specific Plan. The site is located on the west of Temescal Canyon Road and north of Dos Lagos Drive in the City of Corona.

Planning Area 1 of the Dos Lagos Specific Plan was entitled in 2018 and included a 276-unit apartment complex, a 107 room hotel, 6,100 square-feet (SF) of commercial uses, 10,300 SF of restaurant uses (4,000 SF quality restaurant use and 6,300 SF high-turnover sit-down restaurant use), and a 20-fueling position gas station with convenience store and car wash, of which the apartment complex, hotel, and gas station are completed and opened.

The proposed Project consists of replacing the entitled retail and restaurant uses with 50 multifamily (low-rise) apartment dwelling units within eight (8) buildings. In addition, the Project would not install fireplaces or hearths of any type. Access for the proposed apartments will be provided via the existing internal circulation system and no new public access driveway are proposed. This project is the last development piece to Planning Area 1 of the Dos Lagos Specific Plan.

Construction within Dos Lagos Planning Area 1 is generally completed with the exception of this remaining lot. Construction would start early 2024 and be completed less than one year later.

Once construction is completed the proposed project would generate operational air quality emissions. These operational emissions would originate from daily vehicle operations, use of consumer products, and from landscaping equipment.

Air quality impacts related to construction and daily operations were calculated using the latest CalEEMod 2020.4.0 air quality and GHG model, which was developed by Breeze Software for South Coast Air Quality Management District (SCAQMD). The City of Corona recognizes the CalEEMod Version 2020.4.0 as an acceptable model for projects of this nature. The Air Quality modeling is proved as Attachment A to this report.

Regional Air Quality Significance Thresholds
Regional Air quality screening criteria for the City of Corona utilize South Coast Air Quality Management District’s (SQAQMD) Air Quality Thresholds. The screening thresholds for construction and daily operations are shown in Table 1.

Localized Significance Thresholds
In June 2003 the SCAQMD proposed a methodology for calculating Localized Significance Thresholds (LSTs) for NO2, CO, PM2.5 and PM10. The LST methodology was developed to be used as a tool to assist lead agencies to analyze localized impacts associated with project-specific level proposed projects and would not be applicable to regional projects such as general plans.

The LST methodology was last updated to incorporate the most recent ambient air quality Matt McKinlay

standards (July 2008). (South Coast Air Quality Management District, 2008). The LST methodology is often utilized by most agencies governed under SCAQMD CEQA review. SCAQMD developed mass rate look-up tables for projects to assist agencies with development of LSTs (South Coast Air Quality Management District, 2014).

Per the requirements of SCAQMDs LSTs methodology, emissions for gases in attainment such as NO2 and CO are calculated by adding emission impacts from the project development to the peak background ambient NO2 and CO concentrations and comparing the total concentration to the most stringent ambient air quality standards. Also, according to SCAQMD Rule 403, emissions for non-attainment particulate matter such as PM 10 and PM 2.5 can produce no more than 10.4 µg/m3
. The LSTs derived by SCAQMD differentiated by Source Receptor area for which the proposed Project is would be represented by SRA #22 within the City of Corona. The Project was analyzed using a worst-case construction schedule using the appropriate equipment and quantities for this scenario. The Project site would not actively disturb more than 2 acres at any given time. Table 2 shows the worst-case Project LST at 25 meters (SCAQMD, 2009).

Construction of the project would begin shortly after the approval of the Proposed Project subdivision. Mass grading of the lot has been previously completed as part of the master plan so all grading necessary will be minimal and would mainly consist of footing preparations and finish grading, paving and architectural coating. This analysis assumes construction begins in 2024 and would be completed in less than one year. CalEEMod default settings were used which are based on the project site size and number of units proposed. These inputs would be conservative since limited grading is required. The proposed construction schedule and construction equipment list is identified in Table 3.

Expected Construction emissions are based upon CalEEMod modeling assumptions for equipment and durations listed in Table 2 above.

CalEEMod Daily Summer and Winter output is attached to this letter.

Project Related Operational Emissions
As previously discussed, operational emissions from Area, Energy, Mobile sources are also calculated within CalEEMod. The program is largely based on default settings which are automatically populated throughout the model based on the imputed land use. Southern California Edison averages for utility emissions were utilized for the calculations throughout the model. The model assumes that residential units includes a mix of various hearth options. Since the Project would not install hearth options, all hearths were removed from the model.

Traffic Generation was estimated to be 337 average daily trips (LL&G, 2023) and was utilized within CalEEMod. The calculated operational emissions are identified in Table 5 below. In addition, Table 4 include regional SCAQMD significance thresholds and LSTs.

CalEEMod utilized the proposed land use and then estimates worst-case air quality emissions from trip generations built into the model and include vehicle emission rates from EMFAC. The EMFAC model is built into the CalEEMod software. Estimates are provided for both the Summer and Winter operational months.

Based on the findings of the Air Quality modeling in CalEEMod daily operational activities would generate less than significant LST impact and would also generate less than significant regional air quality impacts.

RE: Terrano II Multi-Family Development at Dos Lagos GHG Letter – City of Corona Planning Area 1 of the Dos Lagos Specific Plan was entitled in 2018 and included a 276-unit apartment complex, a 107 room hotel, 6,100 square-feet (SF) of commercial uses, 10,300 SF of restaurant uses (4,000 SF quality restaurant use and 6,300 SF high-turnover sit-down restaurant use), and a 20-fueling position gas station with convenience store and car wash, of which the apartment complex, hotel, and gas station are completed and opened.

The entitled 6,100 SF of commercial uses and the 10,300 SF of restaurant uses have not been constructed and a 2.96 acre undeveloped parcel remains within Planning Area 1. The proposed Project seeks to modify Planning Area 1 of the Dos Lagos Specific Plan and construct a 50-unit multi-family apartment development.

The purpose of this Greenhouse Gas (GHG) letter is to analyze the Project’s GHG emissions and evaluate its conformance with the City of Corona’s Climate Action Plan (CAP). As described in the City’s CAP, there is an existing framework of federal, State, regional, and local policies and regulations that identify GHG reduction requirements within the State. The CAP provides a plan for the City to meet these requirements and achieve local reduction requirements outlined in the CAP (City of Corona, 2019). In addition, showing consistency with the CAP would also demonstrate that the proposed Project would have a less than significant impact under the California Environmental Quality Act (CEQA).

The City of Corona guidelines for determining significance for GHGs under CEQA are identified in the CEQA Thresholds and Screening Tables prepared for the City of Corona by LSA in 2019.

Under this methodology, projects could demonstrate compliance with the City’s Climate Action Plan (CAP) by indicating how the project would achieve 100 points based on the City’s screening checklist guidance. Upon achieving 100 points, the project would equally be screened out with respect to GHG and have a less than significant impact under CEQA. The City’s screening tables give initial guidance for mitigating significance though does not specifically include a numerical screening threshold (City of Corona, 2019). The intent of achieving points essentially is to Matt McKinlay

implement project features to reduce energy consumption or improve the building’s envelope to reduce energy losses.

Since the overall goal of the City’s CAP is to reduce GHG emissions within the City of Corona, reducing GHG intensity from an approved land use would also ensure the City’s GHG inventories are reduced. This letter compares GHG emissions which could be expected should buildout of the remaining SP land uses are constructed and operated with the proposed multi-family residential project. If the proposed Project reduces GHG emission intensity for the remaining

2.96 acre buildout area, the project would have a less than significant GHG impact under CEQA.

GHG emissions from daily operations which would include sources such as Area, Energy, Mobile, Waste and Water uses. Area Sources include usage of consumer products, landscaping and architectural coatings as part of regular maintenance. Energy sources would be from uses such as electricity and natural gas. Solid waste generated in the form of trash is also considered as decomposition of organic material breaks down to form GHGs. GHGs from water are also indirectly generated through the conveyance of the resource via pumping throughout the state and as necessary for wastewater treatment. Finally, the project would also generate air quality emissions and GHG through the use of carbon fuel burning vehicles for transportation. Traffic Generation for the 50 unit apartment project was estimated to be 337 average daily trips (ADT) (LL&G, 2023) while the entitled SP project would generate 1,075 ADT (LL&G, 2023).

GHG impacts related to construction and daily operations for both the entitled development remaining and proposed multi-family developments were calculated using the latest CalEEMod 2020.4.0 air quality and GHG model, which was developed by Breeze Software for South Coast Air Quality Management District (SCAQMD) in 2021. The City of Corona recognizes the CalEEMod Version 2020.4.0 as an acceptable model for projects of this nature. Construction emissions for the site would essential be the same though minimal insignificant variation of GHG Emissions is expected. Given this, only yearly operational emissions are quantified in this analysis and presented for comparison. These models are provided as Attachments A and -B to this letter.

Entitled Commercial and Restaurant Operational Emissions As previously discussed, the remainder development at Dos Lagos Planning Area 1 allows for the construction of 6,100 square-feet (SF) of commercial uses and 10,300 SF of restaurant uses (4,000 SF quality restaurant use and 6,300 SF high-turnover sit-down restaurant use). GHG emissions generated from this land use scenario are shown in Table 1 below and include emissions from default Area, Energy, Solid Waste and Water sources. Mobile emissions were manually updated utilizing scenario based ADT provided by the Project Traffic Engineer (LL&G, 2023). The CalEEMod output for this scenario is provided as Attachment A to this letter.

Based upon the operations emissions modeling as calculated by CalEEMod, the proposed project would generally reduce GHG emissions by 53.7% compared to what would have been otherwise assumed for the 2.96 acre development site. This is largely due to the fact that the commercial and restaurant uses entitled would have a higher energy demand and would generate more traffic as identified by the Project Traffic Engineer. Since the Project would reduce GHG emissions by over half, the proposed Project action would have a less than significant impact on Climate Change and would be consistent with the goals and intent to reduce the City’s GHG emissions spelled out in the City’s CAP. Based on this, the project would not be required to implement GHG design features beyond those required by local state and City regulations.

Therefore, the project would be considered less than significant for GHG emissions.

If you have any questions, please do not hesitate to contact me directly at (760) 473-1253.

GLOSSARY OF COMMON TERMS
Sound Pressure Level (SPL): a ratio of one sound pressure to a reference pressure (Lref) of 20 μPa. Because of the dynamic range of the human ear, the ratio is calculated logarithmically by 20 log (L/Lref).

A-weighted Sound Pressure Level (dBA): Some frequencies of noise are more noticeable than others. To compensate for this fact, different sound frequencies are weighted more.

Minimum Sound Level (Lmin): Minimum SPL or the lowest SPL measured over the time interval using the A-weighted network and slow time weighting.

Maximum Sound Level (Lmax): Maximum SPL or the highest SPL measured over the time interval the A-weighted network and slow time weighting.

Equivalent sound level (Leq): the true equivalent sound level measured over the run time. Leq is the A-weighted steady sound level that contains the same total acoustical energy as the actual fluctuating sound level.

Day Night Sound Level (Ldn): Representing the Day/Night sound level, this measurement is a 24 –hour average sound level where 10 dB is added to all the readings that occur between 10 pm and 7 am. This is primarily used in community noise regulations where there is a 10 dB “Penalty” for nighttime noise. Typically, Ldn’s are measured using A weighting.

Community Noise Exposure Level (CNEL): The accumulated exposure to sound measured in a 24-hour sampling interval and artificially boosted during certain hours. For CNEL, samples taken between 7 pm and 10 pm are boosted by 5 dB; samples taken between 10 pm and 7 am are boosted by 10 dB.

Octave Band: An octave band is defined as a frequency band whose upper band-edge frequency is twice the lower band frequency.

Third-Octave Band: A third-octave band is defined as a frequency band whose upper bandedge frequency is 1.26 times the lower band frequency.

Response Time (F,S,I): The response time is a standardized exponential time weighting of the input signal according to fast (F), slow (S) or impulse (I) time response relationships. Time response can be described with a time constant. The time constants for fast, slow and impulse responses are 1.0 seconds, 0.125 seconds and 0.35 milliseconds, respectively. v

EXECUTIVE SUMMARY
This noise study has been completed to determine the noise impacts associated with the development of the proposed Terrano II Multi-Family Residential project within the approved Dos Lagos Specific Plan EIR. The project consists of developing a 50-unit apartment complex on 2.96 acres. The project site is located east of Interstate 15, north of Dos Lagos Drive and West of Temescal Canyon Road in Planning Area 1 of the Dos Lagos Specific Plan in the City of Corona, CA.

Construction Noise
Construction noise levels at an average distance of 100 feet would attenuate or be reduced 6.0 dBA. Given this and the spatial separation of the equipment, the noise levels are projected to comply with the 75 dBA Leq exterior noise standard over 8 hours at the property lines.

Additionally, Project construction noise levels are considered exempt if activities occur within the hours specified in the City of Corona Municipal Code, Section 17.84.040 of 7:00 a.m. and 8:00 p.m. Monday through Saturday and 10:00 a.m. 6:00 p.m. on Sundays and federal holidays. At the time of this analysis, no Project construction activity is planned outside of the specified hours.

Therefore, no impacts are anticipated and no mitigation is required during construction of the proposed Project. Additionally, all equipment should be properly fitted with mufflers and all staging and maintenance should be conducted as far away for the existing residence as possible.

Construction Vibration
The Federal Transit Administration (FTA) has determined vibration levels that would cause annoyance to a substantial number of people and potential damage to building structures. The FTA criterion for vibration induced structural damage is 0.20 in/sec for the peak particle velocity (PPV). The FTA criterion for infrequent vibration induced annoyance is 80 Vibration Velocity (VdB) for residential uses.

The nearest vibration-sensitive uses are the residences located to the west, 50 feet or more from the proposed construction. The average vibration levels that would be experienced at the nearest vibration sensitive land uses to the east from temporary construction activities were found to be below 0.2 in/sec. Project construction activities would result in PPV levels below the FTA’s criteria for vibration induced structural damage. Therefore, Project construction activities would not result in vibration induced structural damage to residential buildings near the demolition and construction areas. Construction activities were found to generate levels of vibration below 80 VdB and would not exceed the FTA criteria for nuisance for nearby residential uses. Therefore, vibration impacts would be less than significant.

Onsite Transportation Noise
It was determined that the outdoor use areas provided by the common recreation area and the private patios and balconies were found to comply with the City of Corona Noise standards of 65 dBA CNEL without mitigation measures.

An interior noise level reduction of 24 dBA CNEL is needed for the proposed residential units. Based on the preliminary architectural plans provided by Summa Architecture, to meet the 45 dBA CNEL interior noise standard, a minimum STC 28 rated dual pane windows and mechanical ventilation is needed to achieve the necessary interior noise reductions to meet the City’s standard for the residential units.

Once the final architectural plans are prepared, the proposed project site will require an interior noise study be prepared prior to the issuance of building permits to determine the detailed components to reduce interior noise to 45 dBA CNEL.

Offsite Transportation Noise
The Project does not create a direct and cumulative noise increase of more than 3 dBA CNEL on the nearby roadways. Therefore, the Project’s direct contributions to off-site roadway noise increases will not cause any significant impacts to any existing or future noise sensitive land uses. 1 Ldn Consulting, Inc. 1/31/23 22-161 Terrano II Noise

1.0 PROJECT INTRODUCTION

1.1 Purpose of this Study
The purpose of this Noise study is to determine any potential noise impacts due to the proposed construction of the proposed project and also to determine potential noise impacts (if any) to the proposed project generated from offsite sources. Should impacts be determined, the intent of this study would be to recommend suitable mitigation measures to bring those impacts to a level that would be considered less then significant.

1.2 Project Location
The Project site is located in the City of Corona, in the western portion of Riverside County. A general project vicinity map is shown in Figure 1-A. The project site is located east of Interstate 15 and north of Dos Lagos Drive, at the northwest and southwest intersection of Temescal Canyon Road and Fashion Drive in Planning Area 1 of the Dos Lagos Specific Plan within the City of Corona. The project site is bounded to the north by the Home2 Suites by Hilton Hotel, to the west by existing apartments, to the south by a 76 gas station, and to the east by Temescal Canyon Road. Existing retail uses are located further north along Temescal Canyon Road. Existing residential uses are located to the east across Temescal Canyon Road.

1.3 Project Description and Purpose
The proposed project will consist of 50 multi-family units consisting of two-story townhomes and three-story flats across 7 buildings as shown in the Project site configuration provided in Figure 1-B. The homes will range from approximately 700 square feet (s.f.) to 1,300 s.f. and feature one to three bedrooms, depending on the home plan and layout. 2 Ldn Consulting, Inc. 1/31/23 22-161 Terrano II Noise

2.0 FUNDAMENTALS

2.1 Acoustical Fundamentals
Noise is defined as unwanted or annoying sound which interferes with or disrupts normal activities. Exposure to high noise levels has been demonstrated to cause hearing loss. The individual human response to environmental noise is based on the sensitivity of that individual, the type of noise that occurs and when the noise occurs. Sound is measured on a logarithmic scale consisting of sound pressure levels known as a decibel (dB). The sounds heard by humans typically do not consist of a single frequency but of a broadband of frequencies having different sound pressure levels. The method for evaluating all the frequencies of the sound is to apply an A-weighting to reflect how the human ear responds to the different sound levels at different frequencies. The A-weighted sound level adequately describes the instantaneous noise whereas the equivalent sound level depicted as Leq represents a steady sound level containing the same total acoustical energy as the actual fluctuating sound level over a given time interval.

The Community Noise Equivalent Level (CNEL) is the 24-hour A-weighted average for sound, with corrections or penalties for evening and nighttime hours. The corrections require an addition of 5 decibels to sound levels in the evening hours between 7 p.m. and 10 p.m. and an addition of 10 decibels to sound levels at nighttime hours between 10 p.m. and 7 a.m. These additions are made to account for the increased sensitivity during the evening and nighttime hours when sounds appear louder.

A vehicles noise level is generated from a combination of noise produced by the engine, exhaust and tires. The cumulative traffic noise levels along a roadway segment are based on three primary factors: the amount of traffic, the travel speed of the traffic, and the vehicle mix ratio or number of medium and heavy trucks. The intensity of traffic noise is increased by higher traffic volumes, greater speeds and increased number of trucks.

Because mobile/traffic noise levels are calculated on a logarithmic scale, a doubling of the traffic noise or acoustical energy results in a noise level increase of 3 dBA. Therefore, the doubling of the traffic volume, without changing the vehicle speeds or mix ratio, results in a noise increase of 3 dBA. Mobile noise levels radiant in an almost oblique fashion from the source and drop off at a rate of 3 dBA for each doubling of distance under hard site conditions and at a rate of 4.5 dBA for soft site conditions.

Hard site conditions consist of concrete, asphalt and hard pack dirt while soft site conditions exist in areas having slight grade changes, landscaped areas and vegetation. On the other hand, fixed/point sources radiate outward uniformly as it travels away from the source. Their sound levels attenuate or drop off at a rate of 6 dBA for each doubling of distance. 5 Ldn Consulting, Inc. 1/31/23 22-161 Terrano II Noise
The most effective noise reduction methods consist of controlling the noise at the source, blocking the noise transmission with barriers or relocating the receiver. Any or all of these methods may be required to reduce noise levels to an acceptable level.

2.2 Vibration Fundamentals
Vibration is a trembling or oscillating motion of the ground. Like noise, vibration is transmitted in waves, but in this case through the ground or solid objects. Unlike noise, vibration is typically felt rather than heard. Vibration can be either natural as in the form of earthquakes, volcanic eruptions, or manmade as from explosions, heavy machinery, or trains. Both natural and manmade vibration may be continuous, such as from operating machinery; or infrequent, as from an explosion.

As with noise, vibration can be described by both its amplitude and frequency. Amplitude may be characterized in three ways: displacement, velocity, and acceleration. Particle displacement is a measure of the distance that a vibrated particle travels from its original position and for the purposes of soil displacement is typically measured in inches or millimeters. Particle velocity is the rate of speed at which soil particles move in inches per second or millimeters per second.

Particle acceleration is the rate of change in velocity with respect to time and is measured in inches per second or millimeters per second. Typically, particle velocity (measured in inches or millimeters per second) and/or acceleration (measured in gravities) are used to describe vibration.

Table 2-1 shows the human reaction to various levels of peak particle velocity.

Vibrations also vary in frequency and this affects perception. Typical construction vibrations fall in the 10 to 30 Hz range and usually occur around 15 Hz. Traffic vibrations exhibit a similar range of frequencies; however, due to their suspension systems, it is less common, to measure traffic frequencies above 30 Hz.

Propagation of ground-borne vibrations is complicated and difficult to predict because of the endless variations in the soil through which the waves travel. There are three main types of vibration propagation: surface, compression, and shear waves. Surface waves, or Rayleigh waves, travel along the ground’s surface. These waves carry most of their energy along an expanding circular wave front, similar to ripples produced by dropping an object into water. P-waves, or compression waves, are waves that carry their energy along an expanding spherical wave front.

The particle motion in these waves is longitudinal. S-waves, or shear waves, are also body waves that carry energy along an expanding spherical wave front. However, unlike P-waves, the particle motion is transverse, or side-to-side and perpendicular to the direction of propagation.

As vibration waves propagate from a source, the energy is spread over an ever-increasing area such that the energy level is reduced with the distance from the energy source. This geometric spreading loss is inversely proportional to the square of the distance. Wave energy is also reduced 6 Ldn Consulting, Inc. 1/31/23 22-161 Terrano II Noise
with distance as a result of material damping in the form of internal friction, soil layering, and special voids. The amount of attenuation provided by material damping varies with soil type and condition as well as the frequency of the wave.

3.0 SIGNIFICANCE THRESHOLDS AND STANDARDS

3.1 Construction Noise
To control noise impacts associated with the construction of the proposed Project, the City has established limits to the hours of operation. Section 17.84.040 of the City’s Municipal Code indicates that construction noise is prohibited between the hours of 8:00 p.m. to 7:00 a.m., Monday through Saturday and 6:00 p.m. to 10:00 a.m. on Sundays and federal holidays.

Construction noise is defined as noise which is disturbing, excessive or offensive and constitutes a nuisance involving discomfort or annoyance to persons of normal sensitivity residing in the area, which is generated by the use of any tools, machinery or equipment used in connection with construction operations. The City of Corona Municipal Code effectively considers construction noise as exempt if construction noise is limited to the permitted hours of activity.

Neither the General Plan nor Municipal Code establish numeric maximum acceptable construction source noise levels at potentially affected receivers, which would allow for a quantified determination of what CEQA constitutes a substantial temporary or periodic noise increase. To allow for a quantified determination of what the City of Corona Municipal Code constitutes as noise that may be detrimental to the public health, safety or general welfare due to Project construction activity, relevant stationary source noise standards established in Table 1 of Section 17.84.040 are used in this analysis to assess the Project construction noise levels at nearby sensitive receivers. Table 1 of Section 17.84.040 establishes a maximum allowable exterior noise level standard for residential land use of 55 dBA L50 for a cumulative period of more 30 minutes in any hour. This same noise standard limits the exterior noise levels to the noise standard (55 dBA) plus 20 dBA for any period of time. This effectively limits the maximum noise level to 75 dBA Lmax. Therefore, consistent with the City of Corona Municipal Code, an exterior noise level of 75 dBA Lmax is used to describe the maximum acceptable threshold for determining the impacts due to Project construction for sensitive receivers.

3.2 Transportation Noise Standards
To control transportation related noise sources such as arterial roads, freeways, airports and railroads; the City of Corona has established guidelines for acceptable community noise levels in the City of Corona General Plan and Municipal Code. For noise sensitive residential uses, the City has established acceptable exterior noise levels of less than 65 dBA CNEL for outdoor living areas of multi-family dwellings. The applicable thresholds of the City of Corona are provided in Figure 3-A.

California Noise Insulation Standards (California Code of Regulations, Title 24) and the City of Corona Noise Code establish an interior noise standard of 45 dBA for multiple unit and hotel/motel structures. Acoustical studies must be prepared for multiple unit residential and hotel/motel 8 Ldn Consulting, Inc. 1/31/23 22-161 Terrano II Noise
structures that are proposed to be located within the Community Noise Equivalent Level (CNEL) noise contours of 60 dBA or greater. In addition, the City requires all proposed residential structures located within the CNEL noise contours of 60 or greater to prepare an acoustical study.

The studies must demonstrate that the building is designed to reduce interior noise to 45 dBA (CNEL) or lower.

3.3 Construction Vibration Standards
The City of Corona has not identified or adopted vibration standards. However, the United States Department of Transportation Federal Transit Administration (FTA) provides guidelines for maximum-acceptable vibration criteria for different types of land uses. These guidelines allow 80 VdB for human annoyance and 90 VdB for building damage at noise-sensitive uses and buildings where people normally sleep. Construction activity can result in varying degrees of ground-borne vibration, depending on the equipment and methods used, distance to the affected structures and soil type. Construction vibration is generally associated with pile driving and rock blasting.

Occasionally large bulldozers and loaded trucks can cause perceptible vibration levels at close proximity. While not enforceable regulations within the City of Corona, the FTA guidelines of 80 VdB for annoyance and 90 VdB for building damage at sensitive land uses provide the basis for determining the relative significance of potential Project-related vibration impacts. 10 Ldn Consulting, Inc. 1/31/23 22-161 Terrano II Noise

4.0 CONSTRUCTION NOISE AND VIBRATION

4.1 Construction Noise Methodology
Construction noise represents a short-term impact on the ambient noise levels. Noise generated by construction equipment includes haul trucks, water trucks, graders, dozers, loaders and scrapers can reach relatively high levels. Grading activities typically represent one of the highest potential sources for noise impacts. The most effective method of controlling construction noise is through local control of construction hours and by limiting the hours of construction to normal weekday working hours.

The U.S. Environmental Protection Agency (U.S. EPA) has compiled data regarding the noise generating characteristics of specific types of construction equipment. Noise levels generated by heavy construction equipment can range from 60 dBA to in excess of 100 dBA when measured at 50 feet. However, these noise levels diminish rapidly with distance from the construction site at a rate of approximately 6 dBA per doubling of distance. For example, a noise level of 75 dBA measured at 50 feet from the noise source to the receptor would be reduced to 69 dBA at 100 feet from the source to the receptor and reduced to 63 dBA at 200 feet from the source. Additionally, sound levels are logarithmic not linear, so adding two sources of 68 dBA plus 68 dBA is equal to 71 dBA not 136 dBA.

Using a point-source noise prediction methodology, calculations of the expected construction noise impacts were completed using the equation below. The essential model input data for these performance equations include the source levels of each type of equipment, relative source to receiver horizontal and vertical separations, the amount of time the equipment is operating in a given day, also referred to as the duty-cycle and any transmission loss from topography or barriers.

For the grading phase, the equipment needed for the development will consist of a medium sized crawler type excavator, a small to medium sized road grader, a large rubber tired bulldozer, and two tractors/loaders/backhoes. Based on the EPA noise emissions, empirical data and the amount of equipment needed, worst case noise levels from the construction equipment for site preparation would occur during the grading operations.

4.2 Findings and Mitigation for Grading Activities
The grading activities will consist of the preparation of internal roadways, parking and the finished pads. The site has been previously mass graded and the existing grades are already at or near the proposed final grades, therefore, grading would be limited to precise grading activities. The 11 Ldn Consulting, Inc. 1/31/23 22-161 Terrano II Noise equipment will be spread out over the project site from distances near the occupied property lines to distances of 100 feet or more away. The nearest sensitive receptors are the existing residential land uses to the east. The list of equipment and the associated noise levels utilized in this analysis are shown in Table 4-1. The grading equipment will be spread out over the project site from distances near the occupied property lines to distances of 200 feet or more away. Based upon the site plan, on average, the grading operations will occur 100 feet from the property lines. This means that the average distance from all the equipment to the nearest property line is 100 feet.

As can be seen in Table 4-1, at an average distance of 100 feet from the construction activities to the nearest property line would result in a noise attenuation of -6.0 dBA without shielding.

Additionally, the amount of time equipment is operating during a normal work day, referred to as duty-cycle, was assumed to be 8 hours.

Given this, the noise levels will comply with the 75 dBA Leq exterior noise standard over 8 hours at the property lines. Additionally, Project construction noise levels are considered exempt if activities occur within the hours specified in the City of Corona Municipal Code, Section 17.84.040 of 7:00 a.m. and 8:00 p.m. Monday through Saturday and 10:00 a.m. 6:00 p.m. on Sundays and federal holidays. At the time of this analysis, no Project construction activity is planned outside of the specified hours. Therefore, no impacts are anticipated and no mitigation is required during construction of the proposed Project. Additionally, all equipment should be properly fitted with mufflers and all staging and maintenance should be conducted as far away from the existing residences as possible.

4.3 Findings and Mitigation for Construction Vibration
The nearest vibration-sensitive uses are the residences located to the west of the project site, 50 feet or more from the proposed construction. Table 4-2 lists the average vibration levels that would be experienced at the nearest vibration sensitive land uses to the east from temporary construction activities. Loaded trucks will be traveling along the western portion of the site and were assessed at a minimum distance of 50 feet from to be conservative.

The FTA has determined vibration levels that would cause annoyance to a substantial number of people and potential damage to building structures. The FTA criterion for vibration induced structural damage is 0.20 in/sec for the peak particle velocity (PPV). Project construction activities would result in PPV levels below the FTA’s criteria for vibration induced structural damage.

Therefore, Project construction activities would not result in vibration induced structural damage to residential buildings near the construction areas. The FTA criterion for infrequent vibration induced annoyance is 80 Vibration Velocity (VdB) for residential uses. Construction activities would generate levels of vibration that would not exceed the FTA criteria for nuisance for nearby residential uses. Therefore, vibration impacts would be less than significant.

5.0 TRANSPORTATION NOISE

5.1 Existing Noise Environment Onsite
Noise measurements were taken using a Larson-Davis Model LxT Type 1 precision sound level meter, programmed, in "slow" mode, to record noise levels in "A" weighted form. The sound level meter and microphone were mounted on a tripod, five feet above the ground and equipped with a windscreen during all measurements. The sound level meter was calibrated before and after the monitoring using a Larson-Davis calibrator, Model CAL 200.

Monitoring location 1 (ML1) was located at the eastern portion of the project site. The results of the noise level measurement are presented in Table 5-1.

The noise measurement was monitored for a time period of 15 minutes during typical traffic conditions. The existing noise levels in the project area consisted primarily of traffic from Temescal Canyon Road. The ambient Leq noise levels measured in the area of the Project during the afternoon hours was found to be 59.8 dBA. The statistical indicators Lmax, Lmin, L10, L50 and L90, are given for the monitoring location. As can be seen from the L90 data, 90% of the time the noise level is approximately 54 dBA from Temescal Canyon Road. The noise monitoring locations are provided graphically in Figure 5-A.

5.2 Future Onsite Noise Prediction
To determine the future noise environment and impact potentials the Caltrans Sound32 noise model was utilized. The critical model input parameters, which determine the projected vehicular traffic noise levels, include vehicle travel speeds, the percentages of automobiles, medium trucks and heavy trucks in the roadway volume, the site conditions (hard or soft) and the peak hour traffic volume. The peak hour traffic volumes along most roadways range between 6-10% of the average daily traffic (ADT). The capacity in a single freeway lane is 1,950 vehicles per hour due to shortened headways between vehicles (Source: Caltrans). Thus, peak hour traffic values along Interstate 15 were calculated using a worst-case scenario capacity of 1,950 vehicles per hour per lane operating at a Level of Service C.

Table 5-2 presents the roadway parameters used in the analysis. The vehicle mix provides the hourly distribution percentages of automobile, medium trucks and heavy trucks. A traffic mix of

94.39/1.95/3.66 was utilized for Interstate 15 based on Caltrans Annual Average Truck Trip volumes. The Buildout peak hour traffic volume forecasts along Dos Lagos Drive and Temescal Canyon Road were provided in the Terrano at Dos Lagos Traffic Impact Analysis Report by LLG, 2015. The peak hour traffic volumes range between 6-12% of the average daily traffic (ADT).

Per the Caltrans Technical Noise Supplement (November, 2009), 10 percent of the average daily traffic volumes were entered into the noise model to provide a CNEL-equivalent noise output.

The required coordinate information necessary for the Sound32 traffic noise prediction model input was taken from the conceptual site plans provided by Summa Architecture, January 2023.

To determine the future noise levels, the site plans were used to identify the pad elevations, the roadway elevations and the relationship between the noise source(s) and the receptors. To evaluate the future potential noise impacts on the proposed development, outdoor observers were located in the outdoor areas and modeled observers were placed five feet above the finished pad elevation.

The modeled observer locations for the most affected units are presented in Figure 5-B.

Table 5-2 on the following page describes the roadway parameters used in the analysis including the peak traffic volumes, vehicle speeds and the hourly traffic flow distribution (vehicle mix) for the future Buildout conditions. The vehicle mix provides the hourly percentages of automobile, medium trucks and heavy trucks for input into the model.

2 Typical Vehicle Mixed observed in Southern California was used for local roadways.

Outdoor usable space is provided by the common recreational area located in the northeast portion of the project site and by the private patios and balconies at the units. The proposed patios and balconies will be partially shielded from the roadways by the proposed building facades. Typically, three decibels of attenuation is allowed for the first row of buildings when they block 40 to 65% of the line of sight to the noise source, and three to five decibels of attenuation is allowed when the buildings obstruct more than 65% of the line of sight (Source: CALTRANS Technical Noise Supplement Section N-5515). Based on the architectural plans, the proposed patios and balconies will be tucked into the building and will be shielded on one or both sides by the proposed building facades, therefore a factor of 5 dBA was taken into account.

5.3 Exterior Noise Findings and Mitigation
The modeling results for the Buildout analysis are quantitatively shown in Table 5-3. The line of sight at the patios and balconies will be blocked by the proposed building facades, therefore a factor of 5 dBA was taken into account. Therefore, the outdoor use areas were found to comply with the City of Corona’s Noise Standard of 65 dBA CNEL without mitigation. The modeling inputs and outputs are provided as Attachment A.

5.4 Interior Noise Levels
The City requires for residential developments an interior noise limit of 45 dBA CNEL for all residential uses. Based on numerous studies and efficiency standards in current residential Title 24 standards, residential structures provide 15 decibels of reduction with the windows open to the indoor uses and 25 decibels of reduction with the windows closed. This assumes a minimum sound transmission rating (STC) of 28 on the glass assemblies, which is a standard assembly. To maintain a 45 dBA noise level within the residential structures, the building façade noise should be 70 dBA or less. It should be noted: if better/higher STC rated glass assemblies are installed the noise levels would be reduced more than 25 decibels. Therefore, this is a conservative approach.

5.5 Project Related Offsite Transportation Noise
To determine if direct or cumulative off-site noise level increases associated with the development of the proposed project would create noise impacts. The traffic volumes for the existing conditions were compared with the traffic volume increase of existing plus the proposed project. According to the Project traffic study (Linscott Law & Greenspan, 2023), the project is estimated to only generate 337 daily trips with a peak hour volume of 26 trips. The existing average daily traffic (ADT) volumes on the area roadways are more than several thousand ADT.

Typically it requires a project to double (or add 100%) the traffic volumes to have a direct impact of 3 dBA CNEL or be a major contributor to the cumulative traffic volumes. The project will add less than a 5% increase to the exiting roadway volumes and no direct or cumulative impacts are anticipated.

RE: Terrano II Multi-Family Development at Dos Lagos Health Risk - City of Corona The purpose of this Air Quality Heath Risk screening letter is to identify potential health risks at the proposed project site from toxic air contaminants (TACs) originating from Interstate-15 (I15). The proposed Project consists of developing a 50-unit apartment complex within the Dos Lagos Specific Plan. The project site is located within the City of Corona, CA.

This health risk analysis uses the California Office of Environmental Health Hazard Assessment (OEHHA) methodologies (Office of Environmental Health Hazard Assessment, 2015) as outlined by the California Air Pollution Control Officers Association (CAPCOA, July 2009).

Health risk impacts can exist when a project is exposed to toxic emissions and have the potential to impact nearby receptor. Sensitive receptors (and the facilities that house them) in proximity to sources of air pollutants that emit TACs are of particular concern. Exposure to TACs can increase the risk of contracting cancer or result in adverse non-cancer health effects. Non-cancer health risks associated with TAC exposure include birth defects and other reproductive damage, neurological disorders, and damage to the respiratory system (California Air Resources Board, 2005).

Generally, cancer risk can exist within 500-feet of a freeway or busy traffic corridor, but the risk will drop off with distance from a ground level pollution source. Freeways and busy traffic corridors are defined as traffic volume of over 100,000 vehicles per day in urban areas and 50,000 vehicles per day in rural areas (Education Code Section 17312). CARB studies show that air pollution levels can be significantly higher within 500 feet (150 meters) of freeways or busy traffic corridors (SCAQMD, 2005). Generally, in Riverside County, this is applied to education facilities however, it’s reasonable to assess impacts for residential uses as well.

The City of Corona is generally regulated by South Coast Air Quality Management District (SCAQMD). Under SCAQMD guidance, excess cancer risk significance threshold is set at 10 in a million (SCAQMD, 2015).

Cancer risk calculations are often presented on a 9, 30 or 70 year lifetime exposure duration.

The 9 year exposure scenario is based on exposure to children during the first 9 years of life.

Some districts use the 9 year exposure scenario to model short term projects. (CAPCOA, July 2009). For purposes of this analysis, it is reasonable to assume a 30 year duration. For purposes of modeling, AERMOD was used for air quality dispersion modeling and is the preferred/recommended U.S. Environmental Protection Agency (EPA) model for roadway modeling. The software has the ability to incorporate meteorological inputs as well as multiple source and receptor locations and is now used throughout the world. The model input/output is shown in Attachment A to this letter.

The project is adjacent to I-15 north of Dos Lagos Drive and south of Cajalco Road. According to Caltrans, the peak hour traffic is 11,400 trips and the average daily trips are 164,000 ADT (CALTRANS, 2013 Traffic Volumes on California State Highways, 2013). The EMFAC 2021 model was used to develop specific emissions rates for the ADT on the section modeled with AERMOD which was run for the 2025 scenario and is shown in Attachment B to this report. The County wide daily VMT from EMFAC was used to develop normalization factors to calculate ADTs by vehicle type (diesel specific) for the I-15 section analyzed which was ultimately used to derive the total diesel particulates in grams/day generated within the I-15 section analyzed. The emissions were then converted to grams/second which was utilized within AERMOD using a series of adjacent volume sources.

Modeling at the site included coordinates for I-15 and five receptor points which were selected from points on the project site (Receptors 1-5) and represent facility facades. The modeled locations are shown in Figure 1.

Based on discussions with the project applicant, all residential homes constructed as part of this project will have mechanical ventilation filtration systems consistent with the latest building codes such as California’s Title 24. Typical indoor air filtration systems used within todays heating and ventilation systems within California and consistent with Title 24 have a Minimum Efficiency Reporting Value (MERV) rating of 13 (California Energy Commission, 2019).

The US Environmental Protection Agency indicates that MERV 13 filtration systems reduce particulates between 1 and 3 microns by 85% and particles less than 10 microns (PM10) by 90% relative to outdoor ambient air (EPA, 2021).

The annual diesel particulate concentrations at the modeled receptors are summarized below in Table 1 and include the expected reductions within the interior of all residential structures which would have a minimum air filtration system of MERV 13. The modeled output emissions output curves from AERMOD are also shown in Figure 1 below.

Once the dispersed concentrations of diesel particulates are estimated in the surrounding air, they are used to evaluate estimated exposure to people. Cancer Risk Exposure is evaluated by calculating the dose in milligrams per kilogram body weight per day (mg/kg/d). For residential exposure, the breathing rates are determined for specific age groups, so inhalation dose (Doseair) is calculated for each of these age groups, 3rd trimester, 0<2, 2<9, 2<16, 16<30 and 16- 70 years. The following algorithms calculate this dose for exposure through the inhalation pathways. The worst case cancer risk dose calculation is defined in Equation 1 below (OEHHA, 2015):

Equation 1 Doseair=Cair*(BR/BW)*A*EF*(1x10-6 )
Doseair = Dose through inhalation (mg/kg/d)
Cair =
Concentration in air (μg/m3) Annual average DPM concentration in µg/m3 – AERMOD
BR/BW = Daily average breathing rates normalized to body weight (L/kg BW-day).

A = Inhalation absorption factor (assumed to be 1)
EF = Exposure frequency (unitless, days/365 days)
1x10-6 = Milligrams to micrograms conversion (10-3 mg/ μg), cubic meters to liters conversion (10-3 m3/l)
Once the dose is determined then you must calculate the cancer risk. The average daily inhalation dose (mg/kg-day) multiplied by the cancer potency factor (mg/kg-day)-1 will give the inhalation cancer risk (unitless), which is an expression of the chemical’s cancer risk during exposure. For example, an inhalation cancer risk of 5 x 10-6 is the same as stating that an Matt McKinlay

individual has an estimated probability of developing cancer from their exposure of 5 chances per million people exposed.

Cancer risk is calculated by multiplying the daily inhalation or oral dose, by a cancer potency factor, the age sensitivity factor, the frequency of time spent at home and the exposure duration divided by averaging time, to yield the excess cancer risk. As described below, the excess cancer risk is calculated separately for each age grouping and then summed to yield cancer risk for any given location. The worst-case cancer risk calculation is defined in Equation 2 below (OEHHA, 2015).

Equation 2 RISKinh-res=DOSEair × CPF × ASF × ED/AT × FAH RISKinh-res = Residential inhalation cancer risk
DOSEair = Daily inhalation dose (mg/kg-day)
CPF = Inhalation cancer potency factor (mg/kg-day
-1
)
ASF = Age sensitivity factor for a specified age group (unitless) ED = Exposure duration (in years) for a specified age group AT = Averaging time for lifetime cancer risk (years)
FAH = Fraction of time spent at home (unitless)
The results of the cancer risk calculations are shown in Table 2 below. The detailed model input/output is also provided as Attachment C to this report. Based on these calculations, cancer risks from DPM generated from SR-125 would not exceed the 10 per one million exposed thresholds within any units constructed within the Otay Village 8 area.
