land use designations are summarized in the " Surrounding Zoning & Land Uses " table located in the Technical Appendix of this report.

PROJECT ANALYSIS:

(1) Background — The Project site is located within LUA-2N (Arts District- North) of the MU-1 (Downtown Mixed Use) zoning district, requiring the preparation and approval of a Planned Unit Development (“PUD”) to establish the development standards and design guidelines for the site. The Applicant filed a request for approval of the Emporia Work/Live Lofts PUD, File No. PUD21-002, a Conditional Use Permit, File No. PCUP23-011, to establish a work/live operation, and a Development Plan , File No. PDEV21 -011, to construct 9 work/live lofts. On November 20, 2023, the Development Advisory Board recommended that the Planning Commission approve the subject Development Plan. Final approval of the Development Plan is contingent upon the City Council adopting the PUD for the Project site.

(2) Planned Unit Development (File No. PUD21-002) — The LUA- 2N (Arts District- North) of the MU-1 (Downtown Mixed-Use) zoning district, requires the preparation and approval of a PUD to establish the development standards and design guidelines for the site. The proposed Emporia Work/Live Lofts PUD, appended to the attached resolution as "Attachment A,” identifies the following components:

(a) Land Use and Development Regulations — The MU -1 (Downtown Mixed Use) zoning district allows for commercial and residential mixed -use development at a density of 25.1 to 75 dwelling units per acre and a building intensity of 2.0 Floor Area Ratio.

Consistent with the MU -1 zoning district and TOP Downtown District Place Type, the Emporia Work/Live Lofts PUD allows for development of joint work and live quarters, with a maximum building height of 35 feet (3 stories).

(b) Landscaping — The landscaping concept is centered around the use of sustainable and low water use plant materials. As an example, varying species of evergreen and deciduous trees with interest in form and foliage color may be integrated in the landscape design. Pattern and planting should create a visible connection to pedestrian pathways and sidewalks. The PUD also requires the landscaping and irrigation be drought tolerant and meet the current Water Use Classifications of Landscape Species requirements. Due to building placement, t he use of container landscapes is encouraged and may be used along street frontages.

(c) Parking and Circulation — Off- street parking requirements for the Project requires a minimum of 1 parking space per bedroom and 3 spaces per 1,000 gross floor area of works space. All parking space size and location requirements shall conform to the standards set forth in Section 6.03.045 (Off -street Parking Standards) of the Ontario Development Code.

(d) Access to Mass Transit — Omnitrans Route 61, also identified as the future West Valley Connector Bus Rapid Transit (BRT), has existing eastbound bus stops on West Holt Boulevard near South Vine Avenue and South Palm Avenue, and a westbound bus stop on West Holt Boulevard near South Vine Avenue which is less than one quarter of a mile from the Project site.

(e) Architectural Character — The PUD includes architectural design guidelines, specific to the downtown location and mixe d-use building type, and establishes the following design principles:

(i) Create an architectural character that reflects the various styles within the historic downtown by using similar proportions, building details and building material; and

(ii) Create compatibility between the mixed-use architecture and the residential architecture within the downtown area; the introduction of unifying elements such as similar materials and colors should be considered; however, “sameness” is discouraged.

(3) Development Plan (File No. PDEV21-011)

(a) Site Design/Building Layout — The Applicant proposes construction of 3 buildings comprised of 3-plex units for a total of 9 work/live units and is depicted in Exhibit B: Site Plan, attached. The alley-loaded buildings are oriented east to west with the front entries facing a common paseo or perimeter wall with garages located at the rear. The buildings will have 3-stories with an overall height of 34 feet, 6 inches and will be setback 5 feet from Emporia Street; 10 and 5 feet from interior property lines; and approximately 50 feet from the south property line. A single row of parking spaces is located on the southern end of the site.

The units will provide approximately 252 square feet of commercial workspace, bathroom, and a single-car garage for a total of 473 square feet located on the ground level. The second floor, also 473 square feet, is considered the primary living area equipped with a kitchen, dining area, bathroom and living area. Two bedrooms and two bathrooms are located on the third floor for a unit total of 946 square feet of living area and 473 square feet of work/garage area. The commercial workspace storefront entrance will serve as the primary entrance to the upper level r esidential area. Private garages will have direct access to the workspace and upper levels as depicted in Exhibit C: Floor Plans.

(b) Site Access/Circulation — The Project will have two pedestrian access points to the site that leads to the front entries from Emporia Street through common landscape pedestrian pathways. Primary vehicular access to the site is from a 2- way driveway, located on Emporia Street, that leads to a 24 -foot-wide drive aisle providing access to private garages and surface parking spaces.

Work/guest 1,467 3 spaces per 1,000 SF 5 6
TOTAL 23 24

(d) Architecture — The Project will be designed in a contemporary architectural style, as depicted in Exhibit D: Exterior Elevations. The 3 -story buildings will feature aluminum framed storefront glazing surrounded with brick veneer and a metal awning over the storefront that wraps the corner to the front door. The brick veneer continues along the base of the building along the primary view corridors. The main body of the building is finished with stucco and accented with horizontal siding placed near a combination of recessed and flush mounted windows. The building massing is scaled by varying degrees of wall projections, wood insets and recessed windows , creating visual relief. The Project illustrates the type of high-quality residential architecture promoted by the proposed Emporia Work/Live Lofts PUD and the Development Code. This is exemplified through the use of:

 Articulation in the building footprints, incorporating vertical and horizontal changes in the exterior building walls (combination of recessed or projected wall areas);
 Articulation in the varying heights of building roof lines and wall planes;  Recessed windows at key locations; and
 Architectural details, such as the use of decorative trim to compliment the transitions from brick veneer to stucco finishes, awnings above the front entries and windows to enhance openings, and decorative garage doors with windows.

(e) Landscaping — Landscaping is provided for the full length of the Project street frontage, side yards, alley, and pedestrian walkways for a total of 4,237 square feet (21 percent landscape coverage), which meets the minimum 15 percent landscape coverage requirement for the Project. A variety of accent and shade trees in 24-inch, 36- inch, and 48 -inch box and 15- gallon sizes, as well as 1, 5, and 15 - gallon size shrubs, groundcover, and vines will be planted in a variety of species throughout the site to create landscape areas that are aesthetically pleasing while having low or moderate 530

December 18, 2023

water usage. Decorative paving and lighting will be provided at entries, along motor courts, and pedestrian walkways, as depicted in Exhibit E: Landscape Plan.

(f) Signage — All Project signage is required to comply with sign regulations provided in Ontario Development Code Division 8.1. Prior to the issuance of a Building Permit for the installation of any new on-site signage, the Applicant is required to submit Sign Plans for Planning Department review and approval.

(g) Utilities (drainage, sewer) — Public utilities (water and sewer) are available to serve the Project. Furthermore, the Applicant has submitted a Preliminary Water Quality Management Plan ( "PWQMP"), which establishes the Project 's compliance with storm water discharge/water quality requirements. The PWQMP includes site design measures that capture runoff and pollutant transport by minimizing impervious surfaces and maximizes low impact development ( "LID") best management practices ("BMPs"), such as retention and infiltration, biotreatment, and evapotranspiration. The PWQMP proposes the use of an underground filtration system located on the southwest portion of the site .

Any overflow drainage will be conveyed to the public street by way of parkway drains and culverts.

(4) Conditional Use Permit (File No. PCUP2 3-011) —The Development Code requires approval of a Conditional Use Permit to operate work/live Units located within the MU-1 (Downtown- Mixed Use). In conjunction wit h the related Development Plan, the Applicant is proposing to establish 9 Work/Live units with commercial workspace located on the ground floor and residential on the upper 2 levels.

(a) Proposed Use — The work /live units are intended for artists, artisans, professionals, and similarly situated individuals. Artist includes a person who creates art, such as painting, sculpture, music, and performances using conscious skill and creative imagination. Boutique/Artisan Small-Scale and Micro Manufacturing Facilities includes all types of small-scale businesses that produce tangible goods, such as but not limited to , textiles, hardware and hardware prototyping, woodworking, metal working, 3D printing, consumer product design and prototyping, nonalcoholic beverage production, local food production and packaging, soaps, perfumes and lotions. Businesses may provide products directly to the consumer and/or to other businesses. Similarly situated individuals include, but are not limited to, professionals that are engaged i n accounting, legal, architecture, engineering, planning, bookkeeping, academic, and payroll professions.

Artist and artisans may participate in o n-premises sales of goods produced within the work/live unit, and the retail sales activity shall be incidental to the primary production work within the unit. These provisions will allow occasional open studio programs, gallery shows, and participation the Ontario Art Walk. Due to size of the work studio, assembly is limited to no more than 2 people on site for performance artists. All activity will be conducted with the enclosed work studio.

December 18, 2023

Work studio operators are required to reside within the work/live unit and no more than 4 people may reside within each unit. The proposed h ours of operation are Monday through Saturday from 8 am to 8 pm daily. However, the Zoning Administrator may restrict or modify hours of operation for specific business operators and may require a Conditional Use Permit to mitigate pote ntial adverse impacts . Residential interior noise levels may not exceed 45 decibels and exterior noise may not exceed 65 decibels beyond the property lines. The business operator/artist may have up to one employee on site and no more than 2 visitors at time during hours of operation. (b) Land Use Compatibility — The Conditional Use Permit review is required to ensure that the proposed use will be operated in a manner consistent with all local regulations and to ensure that the use will not be detrimental to the public health, safety, or welfare, or materially injurious to uses, properties, or improvements in the vicinity.

The Arts District- North zoning district accommodates a mix of single and multiple -family residential, work/live lofts, artisan co -ops, restaurants, galleries, breweries, and other commercial uses intended to strengthen the economic base of the area. The Project site is located within an existing neighborhood comprised of a mixture of single-family and multiple-family residential, warehouse, commercial and office land uses. The proposed use is consistent with the surrounding residential uses; therefore, no signif icant adverse impacts are anticipated.

Staff believes that the recommended conditions of approval will sufficiently mitigate potential impacts associated with the proposed use and the proposed use is compatible with adjacent land uses.

PUBLIC NOTIFICATION: The subject applications were advertised as a public hearing in at least one newspaper of general circulation in the City of Ontario (the Inland Valley Daily Bulletin newspaper). In addition, notices were mailed to all owners of real property located within a minimum of 300 feet of the exterior boundaries of the property that is the subject of the hearing, as shown on the records of the County Assessor.

CORRESPONDENCE: As of the preparation of this Agenda Report , Planning Department staff has not received any written or verbal communications from the owners or occupants of properties surrounding the Project site or from the public in general, regarding the subject application.

AGENCY/DEPARTMENT REVIEWS: Each City agency/department has been provided the opportunity to review and comment on the subject application and recommend conditions of approval to be imposed upon the application. At the time of the Decision preparation, recommended conditions of approval were provided and are appended to the attached Resolutions as "Attachment A."

AIRPORT LAND USE COMPATIBILITY PLAN (ALUCP) COMPLIANCE: The California State Aeronautics Act (Public Utilities Code Section 21670 et seq.) requires that an Airport Land 532
Planning Commission Agenda Report
File Nos.: PUD21-002, PDEV21-011, and PCUP23-011
December 18, 2023

Use Compatibility Plan be prepared for all public use airports in the State; and requires that local land use plans and individual development proposals must be consistent with the policies set forth in the adopted Airport Land Use Compatibility Plan.

On April 19, 2011, the City Council of the City of Ontario approved and adopted the ONT ALUCP, establishing the Airport Influence Area for Ontario International Airport, which encompasses lands within parts of San Bernardino, Riverside, and Los Angeles Counties, and limits future land uses and development within the Airport Influence Area, as they relate to noise, safety, airspace protection, and overflight impacts of current and future airport activity. As the recommending body for File No. PUD21 -002 and the decision - making body for File Nos. PCUP23 -011 and PDEV21 -011, the Planning Commission has reviewed and considered the facts and information contained in the Application and supporting documentation against the ONT ALUCP compatibility factors, including [1] Safety Criteria (ONT ALUCP Table 2-2) and Safety Zones (ONT ALUCP Map 2-2), [2] Noise Criteria (ONT ALUCP Table 2 -3) and Noise Impact Zones (ONT ALUCP Map 2 -3), [3] Airspace protection Zones (ONT ALUCP Map 2 -4), and [4] Overflight Notification Zones (ONT ALUCP Map 2 -5). As a result, the Planning Commission, therefore, finds and determines that the Project , when implemented in conjunction with the conditions of approval, will be consistent with the policies and criteria set forth within the ONT ALUCP.

COMPLIANCE WITH THE ONTARIO PLAN: The Project is consistent with the principles, goals and policies contained within the Vision, Governance, Policy Plan ( general plan), and City Council Priorities components of The Ontario Plan ("TOP"). More specifically, the goals and policies of TOP that are furthered by the proposed Project are as follows:

413 West Emporia Street Live/Work Project Draft Memorandum for the Record May 22, 2023 Sapphos Environmental, Inc.

EXECUTIVE SUMMARY

This Memorandum for the Record provides the substantial evidence to support the City of Ontario determination that the 413 West Emporia Steet Live/Work Project (proposed project) is eligible for categorical exemption pursuant to Section 15332, Class 32, “Urban Infill Development,” of the State of California Environmental Quality Act (CEQA) Guidelines. The proposed project would construct nine live/work units on an existing paved, vacant lot in the City of Ontario. Pursuant to the requirements of a Class 32 Categorical Exemption, the proposed project would construct an in-fill development project that:

(a) Is consistent with the applicable general plan designation and all applicable general plan policies as well as with applicable zoning designation and regulations. (b) Occurs within city limits on a project site of no more than 5 acres substantially surrounded by urban uses.
(c) Has no value as habitat for endangered, rare or threatened species. (d) Would not result in any significant effects relating to traffic, noise, air quality, or water quality.
(e) Can be adequately served by all required utilities and public services.

The proposed project does not trigger any of the exceptions for use of a categorical exemption, articulated in Section 15300.2 of the State CEQA Guidelines:

(a) Cumulative Impact. Based on a review of past, current, and future projects in the City, there is one street improvement project within 0.25 mile that may include construction simultaneous with the proposed project; however, it would not result in significant cumulative impacts when considered with the proposed project because the proposed project would not involve street closures or similar construction activities.

(b) Significant Effect. No unusual circumstances were identified associated with the baseline conditions that would result in the potential for significant effects as a result of construction, operation, or maintenance of the proposed project.

(c) Scenic Highways. The proposed project would not be visible from any designated or proposed scenic highway.

(d) Hazardous Waste Sites. There are no active listed hazardous waste sites pursuant to Section 65962.5 of the Government Code within the proposed project site.

(e) Historical Resources. The proposed project would not cause a substantial adverse change in the significance of a historical resource.

These determinations were made by Sapphos Environmental, Inc. under the supervision of Laura Male, CEQA Team Supervisor with over 10 years of experience preparing environmental documents pursuant to CEQA; and Rory Baker, who served as project manager, conducted compilation of the environmental data, and prepared the technical analysis.

413 West Emporia Street Live/Work Project Draft Memorandum for the Record May 22, 2023 Sapphos Environmental, Inc.

1.8 Background, Purpose, and Need

The proposed project would provide housing designed towards achieving the City’s goals related to increasing housing and meeting the Regional Housing Needs Assessment (RHNA) allocation.

The 2021-2029 Housing Element of the Policy Plan states that “an adequate supply of quality and affordable housing is fundamental to the economic and social well-being of the residents of Ontario.” The 2021-2029 Housing Element describes strategies proposed to address the RHNA by identifying available sites to accommodate housing. The analysis identified 233 parcels, divided into 10 Housing Opportunity Areas. The proposed project site is located within the Downtown Opportunity Area. The Downtown Opportunity Area was determined to be a convenient location for housing development due to its proximity to transit, existing and planned jobs and amenities, and grocery stores. Additionally, it is well served by infrastructure and utilities, and there are no known requirements for environmental mitigation. 4 The RHNA strategy for the
Downtown Opportunity Area estimates that 11 units within the MU-1 zoning district are expected to be developed within the 2021-2029 RHNA cycle, assuming that it is not built out at full residential capacity or maximum density. The proposed project would develop nine live/work units that would contribute to meeting the housing needs of the City and the RHNA allocation.

Live/work units allow commercial and residential uses within the same unit and typically cater to art-related individuals and businesses, consistent with the project’s location in the Arts District.

The flexibility of this type of housing allows artists and residents to live, work, display, and sell artwork or product in one unit, eliminating the need for maintaining separate residential and commercial spaces.

1.9 Proposed Project

The proposed project would develop nine 3-story live/work units (Attachment 1, Architectural Drawings and Site Plan ). Each unit would be three stories and total 1,109 square feet. The first floor would contain a single-car, single-bike garage, a studio workspace, and a bathroom; the second floor would contain living areas, a kitchen, and a bathroom; and the third floor would contain two bedrooms and two bathrooms. In addition to the 9 garage parking spaces, the site would provide 15 car parking spots and 3 bicycle parking spots. The proposed project would also construct a new, 6-foot-tall block wall on the southern and western perimeters of the site.

The proposed project would involve walkable landscaped areas with a concrete walkway, benches, and three new trees. The proposed project would also involve landscaped areas and nine new trees on the southern perimeter of the site where parking is proposed. Each unit would have three 32-gallon waste cans for refuse, recycling, and green waste. These cans would be stored in each garage and moved on the street for waste collection.

The proposed project would result in the removal of four existing trees: one 18-inch-diameter palm tree on the sidewalk, one 22-inch-diameter tree on the sidewalk, two 24-inch-diameter palm trees near the center of the property. It would also result in the removal of one shrub in the southwestern corner of the property.

The proposed project would include improvements to the sidewalk within the City ROW for the tree removals and for driveway improvements.

1.10 Construction Scenario

Construction assumptions for the proposed proj ect are based on reasonable predictions. Using the same assumptions from the Air Quality Assessment (Attachment 2, Air Quality Assessment and Health Risk Assessment), construction of the proposed project would commence in January 2024 and would take approximately 6 months. Project construction activities would include site preparation and grading (1 day), grading (2 days), tree removal (2 days), driveway improvements and building construction (5 months), paving (7 days), and architectural coating (14 days).

Anticipated construction equipment includes rubber-tired dozers, tractors, loaders, backhoes, graders, cranes, forklifts, pavers, rollers, haul trucks, earthmovers, and air compressors.

The construction staging area for the proposed project would be located within the existing site and would be fenced off from the public. Construction would not require street closures on Emporia Street or Fern Avenue. The proposed live/work development would be maintained by the property owner, including maintenance of the buildings and premises, landscaping, and watering vegetation and trees.

Construction equipment would be turned off when not in use. All heavy equipment would be moved out of the public view at night and would have no conflicts with circulation. The construction contractor would ensure that all construction and grading equipment is properly maintained. All stockpiles would be covered at all times when not in use. Site preparation and construction of the proposed project would be in accordance with all federal, state, and County building codes.

Project Design Features and Regulatory Compliance Measures

Biological Resources

Construction of the proposed project is scheduled to occur during the nesting bird season, which generally occurs between February 1 and September 15. To avoid effects to nesting birds protected under the Migratory Bird Treaty Act (MBTA), the following project design features are included for the proposed project (as applicable):

 If construction activities cannot avoid the nesting bird season, pre-construction nesting bird surveys shall be conducted by a qualified biologist no more than 3 days prior to the start of construction and shall include a 250-foot survey buffer area for non-raptors and a 500-foot buffer survey area for raptors.

 On the first day of construction at the project’s construction footprint, a qualified biologist shall perform a pre-construction “sweep” to identify any bird nests or other resources that may have appeared since the nesting bird survey.

 On each subsequent week of construction during the nesting season, a biological monitor shall first perform a weekly sweep at each work site to look for nesting birds. The weekly sweeps shall be conducted to identify new nests (partially built, active, or inactive) not detected during the preconstruction survey or clearance sweep.

 Should an active nest (containing eggs or chicks) be discovered within or adjacent to the construction footprint during these surveys, a nondisturbance buffer shall be placed around the active nest to prevent impacts to MBTA nesting birds. 558

413 West Emporia Street Live/Work Project Draft Memorandum for the Record May 22, 2023 Sapphos Environmental, Inc.

 Construction shall be halted within the nondisturbance buffer (typically 250 feet for nonraptor species and 500 feet for raptors) until the biologist has determined that the young have fledged and are flying well enough to avoid the proposed construction activities or if the proposed construction activities will not cause the nest to fail. Established buffer sizes depend on site-specific conditions, known tolerances of species, and individual bird behavior and shall be determined by the qualified biologist.

 Active MBTA nests near construction work areas shall be monitored by a qualified biologist. If a nesting bird appears to be stressed as a result of project activities and is at risk of abandoning its nest, the biologist shall halt activity in the immediate area until the bird resumes its normal behavior or until the nest has been determined to no longer be active.

The measures above will reduce the potential for the project to impact nesting birds and ensure compliance with the MBTA.

Construction of the proposed project includes the removal of four trees. In compliance with the City Department of Planning’s Landscape Design Guidelines, 5 the proposed project applicant
would ensure that a qualified landscape architect or certified arborist prepares and submits a tree report to the City which identifies the genus, species, trunk diameter at breast height (DBH), health condition, and reason for removal. The proposed project would also plant a minimum of 10 new 60-inch or 48-inch box size trees to replace the four removed trees at a 2:1 ratio. In addition to the Landscape Design Guidelines, the City provides the following list of measures that would be required for tree protection during construction:
6 1. Identify and preserve existing trees with protective fencing to form a Protected Root Zone (PRZ). This area encircles the tree at the outer most edge of the canopy and protects the roots growing typically within the top 18 to 24 inches of the soil. The PRZ is defined by its critical root radius.

2. Install protective fencing prior to any earthwork and until work is complete. Fencing shall be three feet to four feet in height and installed at the outer most edge of the canopy or PRZ. The temporary fencing shall be chain link fencing or other approved durable material.

Post “Tree Protection Zone – Keep Out” signs on the PRZ fencing.

3. No construction or staging equipment is allowed within the PRZ including heavy equipment that will compact and damage the roots.

4. No disposal of construction materials or by products including paint, plaster, or chemical solutions is allowed within the PRZ.

5. Maintain natural or preconstruction grade within the PRZ. At no time shall soil be in contact with the tree trunk above the root flare.

6. Irrigate the PRZ sufficiently with clean potable water to keep the tree in good health and vigor before during and after construction.

7. Apply a 4- to 6-inch layer of mulch in the PRZ, 1 foot away from the trunk, before construction begins.

8. Any work required to be conducted in the ground within the PRZ shall be accomplished with an air spade to make roots visible and use of hand tools.

9. Pruning for clearance, if needed, shall be done to prevent damaging branches with large equipment. All pruning shall be in accordance with industry standards (International Society of Arboriculture or ANSI A300) under the direction of a Certified Arborist.

10. A Certified Arborist shall be present if more than 33 percent of the root zone is impacted or roots greater than 2 inches or within 5 feet of the trunk will be cut, to ensure tree stability and health. Cuts shall be clean and made at right angles to the roots. Roots shall be cut back to a branching lateral.

11. Pruning cuts or damaged bark shall be cut clean to heal. No tree seal or paint is allowed.

12. Trenches for piping or utilities shall not be constructed with the tree protection zones but shall be rerouted or bored under trees at a minimum of 36 inches deep.

13. Protect soil and roots from compaction in landscape areas used for driveways, storage, or parking with a layer of geotextile fabric and 6 inches of crushed gravel.

14. Trees damaged or destroyed during demolition or construction shall be replaced per the Development Code Tree Preservation Policy and Protection Measures.

Water Quality

Project design features to reduce impacts to water quality would be incorporated into the design.

A Preliminary Water Quality Management Plan (PWQMP; Attachment 3, Preliminary Water Quality Management Plan) has been prepared for the proposed project. Based on review of the PWQMP, the following Best Management Practices (BMPs) would be implemented during construction and operation of the proposed project as project design features to ensure that impacts to hydrology and water quality are less than significant:

 Site Design and Low Impact Development (LID) Practice o Install surface retention basins or infiltration trenches to receive impervious area runoff.
o Install underground stormwater retention chambers where downstream landscaped areas are limited.
o Construct streets, sidewalks, and parking lot stalls to the minimum widths necessary.
 Source Control BMPs
o Minimize non-stormwater site runoff th rough efficient irrigation system design and controllers.
o Provide solid roofs over all trash enclosures.
o Site owner(s) / property manager / home owner’s association (HOA) or property owner’s association (POA) will be familiar with the project Water Quality Management Plan (WQMP) and stormwater BMPs.
o Owner or HOA or POA to provide education/training of site occupants and employees on stormwater BMPs.
o Install stormwater placards/stenciled messages with a “No Dumping” message on all on-site/off-site storm drain inlets.
 Treatment Control BMPs
o Utilize proprietary filter inserts for on-site storm drain inlets or retention basin/trench overflow drains

560

413 West Emporia Street Live/Work Project Draft Memorandum for the Record May 22, 2023 Sapphos Environmental, Inc.

To reduce water quality impacts during construction, the construction contractor shall implement BMPs consistent with the guidelines provided in the California Stormwater BMP Handbook:

Construction,7 for elimination of non-stormwater discharge from the project study area, such as:

 Retaining eroded sediments and other pollutants on the site;  Retaining stockpiles of earth and other construction-related materials on-site;  Proper storage of fuels, oils, solvents, and other toxic materials to prevent spills from being washed into the drainage system;
 Retaining concrete wastes on-site until they can be disposed as solid waste;  Proper covered storage of trash and construction related solid wastes to prevent contamination of rainwater and dispersal by wind;
 Stabilization of roadways to inhibit sediments from being deposited into the public way; and
 Stabilization of any slopes with disturbed soils or denuded of vegetation to inhibit erosion by wind and water.

Grading activities and construction phases of the proposed project would be undertaken during the normal rainy season (October 15 to April 15 for most of Southern California); therefore, BMPs to control surface runoff and soil erosion are required for construction taking place during rainy periods. The construction contractor would implement BMPs consistent with Section 3, “Erosion and Sediment Control BMPs,” of the California Stormwater BMP Handbook: Construction. 8 They
may include:

 Monitor the weather forecast for rainfall. As grading is anticipated to take 2 days, schedule grading operations on days not forecasted for rain.
 Sequence trenching activities so that most open portions are closed before new trenching begins.
 When rainfall is predicted, adjust the construction schedule to allow the implementation of soil stabilization and sediment treatment controls on all disturbed areas prior to the onset of rain.
 Apply soil binder to the soil at least 24 hours before to temporarily prevent water-induced erosion of exposed construction soils.
 Apply rolled erosion control products (RECPs) to cover the soil surface to reduce erosion from rainfall impact, hold soil in place, and absorb and hold moisture near the soil surface.  Outline the limits of the drainage and graded area and indicate proposed devices to control sediment-laden runoff. Sandbag check dams, sediment trap, or a sediment basin may be used.

1.11 Required Approvals

The City Planning Department has reviewed the proposed project and determined that the proposed project is contingent upon Planning Commission approval of the Development Plan and the Conditional Use Permit (CUP) and City Council approval of the Planned Unit Development (PUD). Due to the removal of four trees, the proposed project would be required to submit a tree plan prepared by a qualified landscape architect or certified arborist to the City Planning Department’s Landscape Planning Division. The proposed project also requires a PWQMP (Attachment 3) by the Santa Ana Regional Water Quality Control Board and a project-specific WQMP by the San Bernardino County Municipal Separate Storm Sewer System Permit (MS4 Permit).

2.0 CATEGORICAL EXEMPTION CLASS 32, INFILL DEVELOPMENT PROJECTS

Consistent with the provisions of Section 15332, Class 32, Infill Development Projects, of the 2023 State CEQA Guidelines, the proposed project would construct a live/work development within the urban context of the City. As described in the State CEQA Guidelines, this exemption applies to infill-development projects that meet the following criteria:

(a) The project is consistent with the applicable general plan designation and all applicable general plan policies as well as with applicable zoning designation and regulations.

As previously stated, the proposed project site is designated Mixed-Use by the Land Use Element of the Policy Plan (Figure 4).
9 The MU land use category accommodates a horizontal and/or vertical mixture of retail, service, office, restaurant, entertainment, cultural, and residential uses.

The Policy Plan also categorized the proposed project site as within the Downtown Mixed-Use Area,
10 which is “envisioned as an intensive vertic al and horizontal mixture of retail, office, and residential uses in a pedestrian friendly atmosphere.” 11 The proposed project would develop live/work units that accommodate these various land uses and is therefore consistent with the Policy Plan designation.

As previously stated, the City of Ontario Zoning Map shows that the proposed project site is situated within the MU-1 (Downtown Mixed Use) zoning district (Figure 5). 12 Chapter 5.0, Zoning
and Land Use, of the City of Ontario Development Code (Development Code) establishes the MU-1 zoning district to accommodate a fairly intensive mixture of vertical and horizontal retail and office uses at a development intensity of up to 2.0 floor area ratio (FAR), and residential uses at a density of 25 to 75 dwelling units per acre. The Development Code states that the MU-1 zoning district is consistent with and implements the Downtown Mixed Use Area land use designation of the Policy Plan.
13 The proposed project is consistent with the MU-1 zoning district, as live/work developments such as the proposed project are conditionally permitted in the MU-1 zoning district with a CUP, as shown in Table 5.02-1, Land Use Matrix, of the Development Code.14 Further, the proposed project site is situated in an area of the MU-1 zoning district that restricts land uses to

live/work units, light industrial uses, and commercial uses. 15 Within the MU-1 zoning district, the proposed project site is zoned LUA-2N (Arts District – North). 16 Arts District North is intended to accommodate a mix of work/live lofts, artisan co-ops, restaurants, galleries, breweries, and other commercial uses. Therefore, as a live/work development, the proposed project is consistent with the MU-1 zoning district and the LUA-2N zone.

Therefore, the project is consistent with the applicable general plan designation and all applicable general plan policies as well as with applicable zoning designation and regulations.

(b) The proposed development occurs within city limits on a project site of no more than five acres substantially surrounded by urban uses.

The proposed project site is located within the lim its of the City and is approximately 0.46-acre (Figures 1 and 2). It is substantially surrounded by urban uses, as it is located within the developed context of downtown Ontario. Based on a site visit and desktop review, the proposed project site is surrounded by residential land uses to the north that are designated Mixed Use, commercial land uses to the east and west that are designated Mixed Use, and rail tracks to the south. The land uses south of the rail tracks are designated Industrial. Therefore, the proposed development occurs within city limits on a project site of no more than 5 acres substantially surrounded by urban uses.

(c) The project site has no value as habitat for endangered, rare, or threatened species.

The proposed project site is developed and predominantly paved and has no value as habitat for endangered, rare, or threatened species. There is no designated or proposed critical habitat within the proposed project site. The proposed project would result in no impacts to biological resources regarding any species provided protection under federal, state, and local laws, regulations, policies, or plans. There would be no substantial adverse effect as a result of habitat modifications, nor take, harm, or harassment of any candidate, sensitive, or special status species.

The proposed project site is within a highly urbanized region, surrounded by developed areas consisting of paved streets, sidewalks, parking lots, existing buildings, and train tracks. Existing vegetation includes street trees with the site dominated by non-native weedy species. The proposed project would consist of construction on an existing paved site. All improvements would occur within previously developed areas and would not alter any native vegetation or special status species habitats.

To determine the potential for presence of State and federally listed plant and animal species, Species of Special Concern or wetland resources within the proposed project site, a records search was conducted on May 12, 2023, by Sapphos Environmental, Inc. Qualified Biologist (Ms.

Paulette Loubet), of the California Native Diversity Database (CNDDB) California Native Plant Society (CNPS) Rare Plant Inventory, and the U.S. Fish and Wildlife Service (USFWS) Critical

habitat mapper, and the National Wetlands Inventory (NWI) was queried to determine if jurisdictional wetland features occur within 500 feet of the property. A site visit was conducted on May 15, 2023, to assess the current conditions onsite. No USFWS-designated critical habitat exists within the boundaries of the proposed project site. The nearest USFWS-designated critical habitat is more than 7 miles northwest of the project site. Based on desktop analysis and absence of existing suitable habitat, no federal or California Endangered Species Act (FESA/CESA)–listed species or special status species would be anticipated to be present within the proposed project site.

The CNDDB, the NWI, and aerial imagery were reviewed to identify the nearest riparian habitats and sensitive natural communities near the proposed project site. Based on the desktop analysis and site visit, no riparian habitats or natural communities are present within the boundaries of the proposed project site. Therefore, the proposed project would not impact sensitive natural communities or riverine habitats.

The proposed project would result in no impacts to biological resources regarding the movement of any native resident or migratory fish and/or wildlife species or established native resident or migratory wildlife corridors, or native wildlife nursery sites. A desktop analysis, including review of aerial photographs, was conducted to identify any potential wildlife movement corridors and nursery sites within the proposed project site. No wildlife movement corridors or nurseries were identified in the vicinity of the proposed project. The proposed project site is located within a highly urbanized region surrounded by developed areas consisting of streets, sidewalks, parking lots, existing buildings, and an active railway line. Plant species observed include planted trees and non-native weedy species. The removal of four trees would not result in a significant impact, as these trees do not provide value as habitat for endangered, rare, or threatened species, and the project design features and compliance with the MBTA and City tree removal policies would ensure that impacts to biological resources would not be significant. The site is not directly connected to any native habitat or natural areas and does not function as passageway for wildlife movement; nor is there any contiguous natural habitat through which wildlife would be expected to move. The proposed project is in a highly developed, and proposed project activities would not alter the existing conditions so as to cause impact to biological resources regarding the movement of any native resident or migratory fish and/or wildlife species or established native resident or migratory wildlife corridors, or native wildlife nursery sites.

Therefore, the proposed project site has no value as habitat for endangered, rare, or threatened species.

(d) Approval of the project would not result in any significant effects relating to traffic, noise, air quality, or water quality.

Traffic

The proposed project would not result in conflict with a program, plan, ordinance, or policy addressing the circulation system. The proposed project would not involve any construction within City streets, as all construction would occur within the subject property and on the City sidewalk.

The proposed project would not involve street closures, and Emporia Street would be available for vehicular, bicycle, and pedestrian access during construction and operation of the proposed project. The entirety of Euclid Avenue is a des ignated truck route in the Mobility Element and 565

413 West Emporia Street Live/Work Project Draft Memorandum for the Record May 22, 2023 Sapphos Environmental, Inc.

connects to both Interstate 10 and State Route 60. 17 As such, haul trucks during construction would follow a route consistent with the Mobility Element of the Policy Plan and would use Euclid Avenue to access Emporia Street. Vehicular access for construction vehicles would be provided via Emporia Street, Euclid Avenue, and the proposed project’s two driveways.

The proposed project would not result in conflict in relation to CEQA Guidelines § 15064.3, subdivision (b). The City adopted new VMT thresholds and guidelines in 2020, which are based on guidance from the State Office of Planning and Research (OPR) to establish per capita vehicle miles traveled (VMT) as the primary metric for evaluating transportation impacts under CEQA Guidelines Section 15064.3(b) and Senate Bill (SB) 743. OPR determined that using VMT is a more suitable metric than level of service (LOS) in determining transportation impacts of a project.

The “Resolution Adopting Vehicle Miles Traveled Thresholds” (June 2020) outlines the methodology for VMT assessment for land use projects and defines adopted thresholds of significance for impact assessment (VMT Impact Thresholds). Based on review of the City’s VMT Impact Thresholds, the proposed project would be considered a “Low Trip Generating Use,” as it would provide less than 16 multifamily housing uni ts. As such, the VMT is anticipated to be less than 110 average daily trips and is presumed to be less than significant by the City. 18 The City’s VMT Impact Thresholds state that the cumulative impact of a Low Trip Generating Use is also presumed to be less than significant if it is consistent with the Southern California Association of Government’s (SCAG’s) 2020-2045 Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS), referred to as the Connect SoCal Plan. SCAG’s Connect SoCal Plan identifies several Priority Growth Areas in Ontario for High-Quality Transit Areas, Transit Priority Areas, Neighborhood Mobility Areas, and Livable Corridors, including the proposed project site.
19 The Ontario Plan 2050 (TOP 2050) promotes growth consistent with these Priority Growth Areas, as proposed land use changes under TOP 2050 are intended to encourage walking and biking, put residents in proximity to resources, and align future growth in Ontario with planned infrastructure improvements and regional transportation goals. 20 The proposed project is
a live/work development that would involve both residential and commercial uses on the same property. As residents would work from home or conduct business from the property, the proposed project would reduce VMT by eliminating the need to travel to work and reducing car dependency. Therefore, the proposed project would result in a net benefit for the City to meet the Mobility Element goals to reduce VMT and improve active and multimodal transportation. 21 The
proposed project is consistent with the implementation of TOP 2050; therefore, it is consistent with the SCAG Connect SoCal Plan, and cumulative VMT impacts would be less than significant.

Furthermore, the proposed project site is well-served by public transportation, as it is within 0.1 mile of the Bus Rapid Transit (BRT) corridor on Holt Boulevard and within 0.2 mile of the BRT corridor on Euclid Avenue. 22 The proposed project’s proximity to public transit would further reduce VMT generated by residents. Therefore, the proposed project would not result in conflict with a program, plan, ordinance, or policy addressing the circulation system, and it would not result in conflict with CEQA Guidelines § 15064.3, subdivision (b).

The proposed project would not result in a significant impact related to substantially increasing hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment). The proposed project involves no changes to the design or route of any streets or intersections. The existing sidewalk would temporarily undergo construction for tree removals and driveway improvements, after which it would remain open for pedestrian use. The driveways and sidewalks adjacent to the proposed project would be compatible with the existing street. The driveway throughout the property does not contain any sharp curves, roundabouts, or hazardous geometric design features. Emporia Street in front of the proposed project site currently allows par king for approximately seven vehicles. After the proposed project, approximately 68 feet along the front of the property would be designated “No Parking” at all times with the appropriate striping and signage, reducing street parking to approximately three vehicles. The removal of four street parking spaces would not result in a significant impact to parking in the area. Further, the proposed project would provide on-site parking for residents consistent with the City requirements, including 9 garage parking spaces and 15 additional parking spaces. The changes in parking from the existing conditions would not create a traffic hazard. Additionally, the proposed live/work development is similar to the surrounding residential and commercial land uses and would have compatible traffic patterns.

Therefore, the proposed project would not result in a significant impact related to substantially increasing hazards due to a geometric design feature or incompatible uses.

The proposed project would not result in inadequate emergency access. As previously stated, the proposed project would not involve any construction within City streets, all construction would occur within the subject property and on the City sidewalk, and the proposed project would not involve street closures. Therefore, Emporia Street and surrounding streets would be available for emergency access during construction and operation of the proposed project. During operations, emergency access to the proposed project site w ould continue to be available along Emporia Street and would be accessible on the property driveways. Therefore, the proposed project would not result in inadequate emergency access, and it would not result in a significant impact to traffic.

Noise

A Noise Assessment (Attachment 4, Noise Assessment) was prepared for the proposed project and determined that the proposed project would not a result in a significant impact due to noise.

The proposed project would not generate a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance.

The City Noise Ordinance also establishes an exterior noise standard of 70 A-weighted decibels (dBA) for the proposed mixed use residential project (Table 1, City Noise Ordinance Standards).

As stated in the Noise Assessment, construction noise levels are considered exempt by the City if the activities occur within the hours specified in the City of Ontario Municipal Code:

 7:00 a.m. and 6:00 p.m., Monday through Friday
 9:00 a.m. and 6:00 p.m., Saturday and Sunday

All construction activity from the proposed project would occur during the specified hours and would therefore be exempt from the 70 dBA noise standard. Therefore, there would be no impact regarding the generation of noise levels in excess of the Noise Ordinance.

The proposed project would not result in significant impacts in relation to generation of excessive groundborne vibration or groundborne noise levels. As stated in the Noise Assessment, ground- borne vibration from the anticipated construction activities and equipment at distances of 10 feet would not create vibration amplitudes that causes structural damage to nearby structures. Since the proposed project is not expected to employ any pile driving or rock blasting equipment, and the nearest sensitive receptor is located over 50 feet from the nearest point of construction activities, impacts from groundborne vibration would not be significant.

The proposed project would not result in significant impacts due to exposing people to excessive noise levels within two miles of an airport. The proposed project is located approximately 1.5 miles from the Ontario Airport and is located within the Ontario Airport Influence Area in the Land Use Element.
24 However, the Noise Assessment determined that the noise from the airport would not have a significant impact on the proposed project based on the Ontario International Airport Land Use Compatibility Plan (OIALUCP). According to the OIALUCP, the proposed project is located within the 60 to 65 dBA community noise equivalent level (CNEL) noise impact zone, at approximately the 64 dBA CNEL contour or lower, within the Airport Influence Area (AIA). Based on the proposed multi-family residential land use for the proposed project, the OIALUCP identifies noise policies and criteria to minimize the interior noise exposure generated by aircraft activity.

The noise criteria on Table 2-3 of the OIALUCP indicates that multi-family residential uses located within the 60 to 65 dBA CNEL noise impact zone are considered normally compatible land use and must satisfy an interior noise level standard of 45 dBA CNEL. Therefore, impacts due to the airport noise levels would not be significant, and the proposed project would not result in significant impacts due to noise.

Air Quality

The proposed project would result in less than significant impacts and was evaluated in consideration of Appendix G of the State CEQA Guidelines. An Air Quality Assessment was prepared by Ldn Consulting, Inc. for the proposed project (see Attachment 2). The evaluation is based on estimated emissions calculated using the California Emission Estimator Model® (CalEEMod) version 2022.1, a web-based software developed by the California Air Pollution Control Officers Association (CAPCOA) in collaboration with California air districts specifically for land use development projects. The CalEEMod input/output model is provided as an attachment to the Air Quality Assessment (Attachment 2). The proposed project’s construction emissions would result from off-road equipment usage, on-road vehicle travel, fugitive dust, architectural coating, and paving off-gassing; and operation emission would be generated from associated residential use and maintenance activities.

The construction schedule utilized in the analysis represents a “worst-case” analysis scenario as emission factors for construction equipment decrease as the phasing schedule time increases, due to improvements in technology and more stringent regulatory requirements. The duration of construction activities would be approximately 6 months, from January 2024 to June 2024, and the associated construction equipment represents a reasonable estimate of the construction fleet required. The construction scenario assumes construction activities would occur in the following phases: demolition, site preparation, grading, building construction, paving, and architectural coating. Construction equipment for the proposed project would include rubber-tired dozers, tractors/loaders/backhoes, graders, cranes, forklifts, paving equipment, rollers, and air compressors.

Air Quality Plans. The proposed project would be required to comply with the South Coast Air Quality Management District (SCAQMD) rules and regulations:
25 Rule 403 (Fugitive Dust), Rule
402 (Nuisance), Rule 403 (Fugitive Dust), Rule 1401 (New Source Review and Toxic Air Contaminants) and Rule 1113 (Architectural Coatings); and the 2022 SCAQMD Air Quality Management Plan (2022 AQMP). 26 The proposed project would be required to comply with all federal, state, and city regulations, including the California Green Building Code and City of Ontario Municipal Code.

2022 Air Quality Management Plan

The construction, operation, and maintenance of the proposed project would not cause a violation of the SCAQMD AQMP because it would not impede the ability of the basin to achieve the NAAQS attainment deadlines for those pollutants not in attainment. Designations for attainment are determined from the ambient air quality. The 2022 AQMP includes strategies to achieve the required NOx reductions through the extensive use of zero emission technologies across all stationary and mobile sources; and incorporates transportation strategies and control measures provided in the SCAG Connect SoCal Plan.

A significant air quality impact may occur if a project is inconsistent with the AQMP or would in some way represent a substantial hindrance to employing the policies or obtaining the goals of the plan. Construction of the proposed project would result in emissions from the use of construction equipment during each phase and vehicl e exhaust from worker and haul trips. The project’s daily construction and operation emi ssions associated would be below the SCAQMD daily emissions thresholds of significance (see Table 3, Estimated Daily Construction Emissions; Table 4, Estimated Daily Operational Emissions ). The maximum estimated daily emissions for each construction year would not exceed the daily construction significance threshold provided by SCAQMD.

Based on the results of the CalEEMod model, maximum daily construction emissions for the proposed project would contribute to less than 12 percent (0 to 12 percent, depending on pollutant) of the SCAQMD daily significance construction thresholds. Since construction activities would occur for a duration of 6 months and equipment would be utilized in accordance with the SCAQMD rules and regulations, construction activities are not anticipated to result in a substantial increase in emissions. The proposed project would also comply with all applicable construction standards and requirements including limiting c onstruction and maintenance activities to 7:00 a.m. to 6:00 p.m. on weekdays and between 9:00 a.m. and 6:00 p.m. on Saturdays and Sundays.

The implementation of additional best management practices would be implemented to further contain construction generated dust and reduce potential air quality impacts.

571

413 West Emporia Street Live/Work Project Draft Memorandum for the Record May 22, 2023 Sapphos Environmental, Inc.

Operational emissions were quantified using the same method as construction (see Attachment 2); operational and maintenance activities for the proposed project result in less than significant impacts to air quality and would not exceed the operation significance thresholds (see Table 4).

Maximum operational daily emissions for the proposed project would contribute to less than 1.5 percent of SCAQMD daily significance thresholds. The proposed project would not be considered a significant regional emissions contributor; would not violate any air quality standards or contribute to any existing or project air quality vi olations; and would not cause a violation of the SCAQMD AQMP because it would not impede the ability of the basin to achieve the NAAQS attainment deadlines for those pollutants not in attainment.

The proposed project would generate vehicle trips associated with new residents and visitors, but it would not result in a substantial increase in regional employment or population growth reflected in the AQMP assumptions. The proposed project is anticipated to result in an increase of 66 weekday vehicle trips per day during operation. Based on review of the City’s VMT Impact Thresholds, the proposed project would be considered a “Low Trip Generating Use,” as it would provide less than 16 multifamily housing units. As such, the VMT is anticipated to be less than 110 average daily trips and is presumed to be less than significant by the City. 28 The proposed
project would be consistent with the AQMP’s goals to invest in strategies that improve air quality by providing residential units next to commercial and mixed-used land uses, with enhanced pedestrian and public transit access.

2022 Community Climate Action Plan Update

The proposed project would be consistent with TOP 2050 and the 2022 Ontario Community Climate Action Plan (2022 CCAP) implemented under TOP 2050. The proposed project would provide residential units adjacent to mixed use areas, providing pedestrian access to commercial and employment opportunities. Operation of the proposed project would result in improvements to existing air quality by improving access between residential and commercial areas, utilizing the existing transportation network, and encouraging alternative transportation modes. The proposed project site is served by the Ontario train station and nine bus stops within a half-mile radius of the project site. While the proposed project would generate an increase in daily vehicle trips, the proposed project would result in reduced VMT by strategically developing residential units adjacent to existing access and connectivity to provisions. The proposed project would be consistent with regulations and the 2022 CCAP related to reducing greenhouse gas (GHG) emissions and would contribute to the cumulati ve decrease of emissions within the City. The proposed project would, therefore, be consistent with the 2022 CCAP.

Sensitive Receptors. The proposed project would result in less than significant impacts to air quality in relation to exposing sensitive receptors to substantial pollutant concentrations. Land uses identified to be sensitive receptors by SCAQMD in the CARB’s Air Quality Handbook include residences, schools, playgrounds, childcare centers, athletic facilities, long-term health care facilities, rehabilitation centers, convalescent centers, and retirement homes. 29 The project site is

surrounded by existing residential to the north across West Emporia Street, existing commercial uses to the east and west, and the Union Pacific Railroad to the south, which services the Metrolink Riverside Line and operates diesel-powered locomotives. The Ontario Station is located to the east across Euclid Avenue. The sensitive receptors surrounding the project site include mixed use areas with commercial and residential units surrounding the proposed project site. As previously stated, the construction of the proposed project would result in temporary and maximum operational daily emissions that would contribute to less than 1.5 percent of SCAQMD daily significance thresholds. Given that the estimated daily construction emissions are well below the SCAQMD thresholds, there would not be significant emissions produced by the proposed project in the vicinity of sensitive receptors, and impacts would be less than significant. Operation of the proposed project would be similar to surrounding uses and would not result in a substantial increase of air quality emissions to sensitive receptors.

In addition to the regional emissions analysis, Localized Significance Thresholds (LST) methodology was used to determine impacts to sensitive receptors. SCAQMD recommends using LST methodology for the Source Receptor Area (SRA) 32, which incorporates background ambient air quality data and sensitive receptor distance as a function of calculating impacts. The worst-case LST assumed for the proposed project is located 25 meters from the center of the proposed project area; and allowable emissions for 1-acre project site were used to evaluate the proposed 0.46-acre project site. The LST analysis uses a daily emissions threshold for NO x, CO,
PM2.5, and PM 10 (Table 5, Estimated Daily Construction Emissions – LST Analysis for 1 Acre ).

The proposed project would not exceed LST analysis screening thresholds and would have temporary, less than significant impacts during construction activities.

Odors. The Air Quality Assessment (Attachment 2) determined that the proposed project would not create any objectionable odors that would impact the sensitive receptors in the project vicinity or a substantial number of people. In determining the significance of other emissions (such as odors), potential impacts are based on what is known about the odor compound quantities resulting from a proposed use, the type of neighboring uses potentially affected, the distance between point sources and neighboring uses such as sensitive receptors, and the resultant concentrations at receptors. According to the CARB’s Air Quality Handbook, 30 land uses and
industrial operations associated with odor complaints include agricultural uses, wastewater treatment plants, food processing plants, chemical plants, composting, refineries, landfills, dairies,

and fiberglass molding. Construction of the proposed project would not be expected to generate objectionable odors and would not result in a significant impact. Long term operations of the proposed project would be associated with residential uses, which would not create any offensive odors resulting in nuisance. The proposed project is, therefore, not anticipated to result in objectionable odors and would have no impact.

To determine cumulatively considerable impacts to air quality, SCAQMD recommends an evaluation to determine if construction-rela ted emissions and operational emissions from individual development projects exceed the mass daily emissions thresholds for individual projects. The SCAQMD neither recommends quant ified analyses of the emissions generated by a set of cumulative development projects; however, estimated daily construction and operational emissions are well below the SCAQMD thresholds. The proposed project would not result in or require rezoning of the existing site and would be constructed to be compatible with the City of Ontario’s General Plan. The proposed project’s air quality impacts would be considered less than significant and would not result in cumulative ly considerable impacts, even though the region is nonattainment under applicable federal and state ambient air quality standards. Therefore, the proposed project would not result in a significant impact due to air quality.

Hydrology and Water Quality

The proposed project would result in less than significant impacts to hydrology and water quality in regard to water quality standards or waste discharge requirements and would not substantially degrade surface or groundwater quality. As stated above, project design features to reduce impacts to water quality would be incorporated. The construction contractor would implement BMPs consistent with the guidelines provided in the California Stormwater Best Management Practice Handbooks: Construction, for elimination of non-stormwater discharge from the project study area such as: retaining eroded sediments and other pollutants on the site; retaining stockpiles of earth and other construction-related materials on-site; proper storage of fuels, oils, solvents, and other toxic materials to prevent spills from being washed into the drainage system; retaining concrete wastes on-site until they can be disposed as solid waste; proper covered storage of trash and construction related solid wastes to prevent contamination of rainwater and dispersal by wind; stabilization of roadways to inhibit sediments from being deposited into the public way; and stabilization of any slopes with disturbed soils or denuded of vegetation to inhibit erosion by wind and water.

The proposed project is anticipated to begin construction in January 2024, with grading and other construction activities lasting up to 6 months. Grading activities and construction phases of the proposed project would be undertaken during the normal rainy season (October 15 to April 15 for most of Southern California); therefore, BMPs to control surface runoff and soil erosion shall be required for construction taking place during rainy periods (please see Section 1.10, Construction Scenario, for a list of erosion control BMPs).

As specified Section 1.10, the proposed project would incorporate appropriate BMPs that are designed to reduce the potential pollutants of concern in the project’s surface water runoff during both operation and construction. The PWQMP woul d be implemented to ensure that BMPs are functioning properly and are effective at treating runoff from the site throughout the life of the project. The project would incorporate BMPs that would actively or passively treat stormwater before discharging to the local storm drain system. Therefore, the proposed project would have less than significant impacts regarding violating water quality standards or waste discharge requirements or otherwise substantially degrade surface or groundwater quality.

413 West Emporia Street Live/Work Project Draft Memorandum for the Record May 22, 2023 Sapphos Environmental, Inc.

The proposed project site is approximately 0.46 acre and is currently a paved, flat, and vacant lot.

The site drains from north to south and has no offsite storm water contribution based on field topographic surveying completed by EGL Associates Inc in February 2023 (Attachment 5, Hydrology Analysis ). The PWQMP determined that the project site contains 0.36 acre of impermeable surface, or approximately 78 percent of the site (Attachment 3). The proposed project would reduce the impermeable surface area of the project site to 0.33 acre (72 percent) and increase groundwater recharge. The proposed project would not result in significant impacts regarding decreasing groundwater supplies or interference with groundwater recharge such that the project may impede sustainable groundwater management of the basin.

The proposed project is considered a priority project and is required by the Santa Ana Regional Water Quality Control Board to prepare a PWQMP (Attachment 3), as well as required by the San Bernardino County MS4 Permit to prepare a project-specific WQMP. The PWQMP anticipates installing underground stormwater retention chambers below the parking area to receive impervious area runoff. Therefore, the proposed project would not affect groundwater supplies nor interfere substantially with groundwater recharge. The PWQMP anticipates that surface water flows from the entire drainage area can be retained and infiltrated by the proposed stormwater retention chambers, which would be the StormTech MC-7200 underground infiltration system with Flogard Plus FGP-12F installed in the catch basin to prevent trash and debris from entering. Any overflow of stormwater would drain to the Em poria Street storm drain system and would follow the same drainage pattern as the existing conditions towards the East State Storm Drain. 31 The
amount and rate of runoff is anticipated to be less than that of the existing conditions, as the site would become more permeable, and stormwater would be retained and then infiltrated onsite.

Therefore, the proposed project would not substantially alter existing drainage patterns; nor would it substantially increase the rate amount of surface runoff in a manner that would result in flooding, create, or contribute runoff water which would exceed the capacity of existing or planned stormwater systems, or provide substantial additional sources of polluted runoff. Therefore, there would be no impact.

A Preliminary Hydrology Report (Attachment 5) and an Infiltration Study (Attachment 6, Report of Geotechnical Engineering Investigation) determined that the site has adequate infiltration should the project pursue an infiltration system for rainwater runoff at the site. The percolation test concluded that dispersal of on-site stormwater runoff by infiltration system is considered feasible from a geotechnical engineering standpoint (Attachment 6). The stormwater infiltration mechanisms outlined in the PWQMP would have a net benefit to groundwater recharge, decrease the rate and flow of runoff entering the storm drain system, and benefit existing drainage patterns by capturing and infiltrating stormwater flows from the site. Therefore, there would be no impact.

The proposed project would have no impact in regard to substantially altering the existing drainage pattern of the site or area including through the alteration of the course of a stream or river through the addition of impervious surfaces, in a manner that would result in substantial erosion or siltation on- or off-site; substantially increase the rate or amount of surface runoff in a manner that would result in flooding on- or off-site; create or contribute runoff water that would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff; impede or redirect flood flows; or be located in flood hazard, tsunami, or seiche zones. The slight increase of impervious surfaces would not be substantial enough to significantly alter the course of a stream, river, or existing drainage pattern. Grading of

the current site would be almost the same as the proposed project site. The BMPs used during the construction phase would significantly reduce the potential for erosion or siltation offsite.

According to the Federal Emergency Management Agen cy map, the project site is not located within a 100-year flood hazard zone or a special flood hazard area (Attachment 7, EDR Database Records Search Results ).32 Therefore, the proposed project would not result in a significant impact due to water quality.

(e) The site can be adequately served by all required utilities and public services.

Based on review of the Housing Element of the Policy Plan, water and wastewater services are provided by the Ontario Municipal Utilities Comp any (OMUC), which is a department of the City.

The City maintains a wastewater collection system and contracts with the Inland Empire Utilities Agency (IEUA) for wastewater treatment.
33 The Housing Element states that the City prioritizes water and sewer hook ups for all new residential developments.

The Housing Element evaluates the status of current infrastructure capabilities and capacities of different areas of the City. It states that the Downtown Housing Opportunity Area is well served by utilities infrastructure. The City installed sewer infrastructure along East Holt Boulevard to accommodate development projected under the Policy Plan, including the proposed project. It states that the sewer capacity is adequate to serve the projected new residential and commercial development in the Downtown Housing Opportunity Area. Additionally, it states that there is adequate water for the sites and no known environmental constraints. While storm drain capacity upgrades have been recommended, this is not anticipated to be a constraint to development. The City is also working to build OntarioNet, a new fiber-optic internet service throughout the city. The first fiber lines serving Ontario have already been installed in the areas around downtown, near where the proposed project is located. Each unit would be provided with three 32-gallon waste cans for refuse, recycling, and green waste to store in the garage. Occupants of each unit would move the waste cans to the street for collection by refuse vehicles. Solid waste collection and disposal in landfills is provided by the City’s Integrated Waste Department. Electricity is provided by Southern California Edison, and natural gas is provided by Southern California Gas Company.

Police protection services are provided to the City by the City Police Department in the West Area Command, and fire protection services are provided by the City Fire Department. The proposed project site is served by the Ontario-Montclair School District, within the service boundaries of Euclid Elementary School and Vira Danks Middle School.
34 It is also served by Chaffey Union
Joint High School District, within which the nearest high school is Chaffey High School.35

The population of the City is estimated to be approximately 177,963 persons. 36 The addition of
nine live/work units would result in a maximum population increase of 36 persons, as the City Development Code states that the “residential occupancy in any work/live unit shall not exceed 4

persons.”37 This would result in approximately 0.02 percent population growth, and it would not represent a significant increase in the population of the City such that it would result in a greater demand for utilities or publics services. As the proposed project site is located within the urbanized context of downtown Ontario and is surrounded by residential and commercial land uses, the existing utilities infrastructure and public services are available to serve the proposed project site.

As previously stated, the Housing Element states that the area is well-served by utilities and accommodates the development projected under the Policy Plan.

In addition, the project developer would be required under California Government Code 65995 and Education Code 17620 to pay the applicable developer fees towards utilities infrastructure and public services, including police, fire, streets, storm drainage, water, parks, libraries, sewer, solid waste, and school district. Paying these fees would ensure that the site would receive adequate service.

Therefore, the site can be adequately served by all required utilities and public services.

Therefore, the proposed project meets the eligibility requirements and would be consistent with the provisions of the applicable Categorical Exemption pursuant to Section 15332 of the 2023 State CEQA Guidelines.

3.0 EXCEPTIONS

It has been determined that the proposed project is eligible for use of the Categorical Exemption because it falls within the description of the categorical exemption and there are no applicable exceptions to the exemptions as provided in Section 15300.2 of the State CEQA Guidelines.

3.1 Cumulative Impact

Section 15300.2(b) of the State CEQA Guidelines establishes that all exemptions are inapplicable when the cumulative impact of successive projects of the same type in the same place over time is significant. To determine if the proposed project has the potential to result in a substantial adverse cumulative effect, other past, current, and reasonably foreseeable projects were reviewed. The potential for cumulative impacts was evaluated with regard to projects that could be reasonably expected to have significant ad verse impacts on people and environment in the same place (0.25-mile radius) over time.

This City Planning Department’s website provides a list of Environmental Impact Reports (EIRs) for current projects as well as past adopted EIRs. All 29 EIRs for development projects in the City were considered for the proposed project’s potential contribution towards cumulative impacts.

Two past, current, or future projects were found to be located within 0.25 mile of the proposed project site or contain the proposed project site:
38  Tessier Work/Live Project Final EIR (approved 2003, State Clearinghouse [SCH] No. 2002121078)
 TOP 2050 Final EIR (approved 2022, SCH No. 2021070364)

The Tessier Work/Live Project consists of restoring and renovating four vacant structures within the boundaries of Euclid Avenue to the east, Holt Avenue to the north, Vine Avenue to the west, and the trail tracks to the south.
39 As the Final EIR for the Tessier Work/Live Project was approved in 2003, construction would not overlap with construction of the proposed project, and there would be no cumulative construction impacts. A succession of live/work developments over time in the vicinity of the proposed project would result in a net benefit in support of the Downtown Arts District area.

The only programmatic document that Included the proposed project site was the TOP 2050 EIR.

The TOP 2050 EIR analyzed cumulative impacts due to housing projects within the City and determined that additional housing constructed under the Policy Plan (such as the proposed project) would not result in a significant adverse cumulative impact. 40 The TOP 2050 EIR states that implementation of the plan is designed to increase housing opportunities throughout the City, provide land use designations for a variety of housing types

and provide for additional residential opportunities throughout the City. 41 TOP 2050 includes policies that support an increase in the provision of housing and diversity of housing opportunities in the City (Table 6, Proposed Project Consistency with TOP 2050 Policies).42

TABLE 6
PROPOSED PROJECT CONSISTENCY WITH TOP 2050 POLICIES

Housing Element Policy Proposed Project Consistency
H-2.6: Infill Development. We support the revitalization of neighborhoods through the construction of higher-density residential developments on underutilized residential and commercial sites.

The proposed project is an in-fill development that would utilize an otherwise vacant site with limited opportunities for residential development, as its zoning restricts development to work/live projects, industrial uses, or commercial uses.

ER-4.1: Land Use. We reduce GHG and other local pollutant emissions through compact, mixed-use, and transit-oriented development and development that improves the regional
jobs-housing balance.

The proposed project is a mixed-use development that would provide residents with the space to conduct their job in the same area as they are provided housing. The proposed
project would result in a net reduction of GHG emissions and other local pollutants by placing residents at their place of work, eliminating the need to drive to work and reducing car dependence.

CE-1.6: Diversity of Housing. We collaborate with
residents, housing providers, and the development
community to provide housing opportunities for every stage of life; we plan for a variety of housing types and price points to encourage the development of housing supportive of our efforts to attract business in growing sectors of the
community while being respectful of existing viable uses.

The proposed project is a live/work development, which
would provide a less common type of housing opportunity that encourages both housing and jobs, therefore
contributing to a diversity of housing.

In addition, SCAG’s Connect SoCal Plan identifies several Priority Growth Areas in the City for High-Quality Transit Areas, Transit Priority Areas, Neighborhood Mobility Areas, and Livable Corridors, including the proposed project site.
43 TOP 2050 promotes growth consistent with these
Priority Growth Areas, as proposed land use changes under TOP 2050 are intended to encourage walking and biking, put residents in proximity to resources, and align future growth in Ontario with planned infrastructure improvements and regional transportation goals. 44 The proposed project is
consistent with SCAG’s Connect SoCal Plan, as it is located within one of the identified Priority Growth Areas and is consistent with the implementation of TOP 2050.

When considered cumulatively with other housing projects in the City, the proposed project would not result in a substantial adverse cumulative impact but, rather, a net benefit due to the increase

in housing. The proposed project is consistent with SCAG’s Connect SoCal Plan and TOP 2050, and it would result in a net benefit for the City.

Additionally, the City’s Capital Improvement Program (CIP) website was reviewed for any street, sidewalk, storm drain, utility relocation, and grade separation improvement projects throughout the City. There is one CIP project within 0.25 mile of the proposed project site: the Vine Avenue and B Street Bike Boulevard Project. This project will provide street lighting, traffic calming measures, and a designated bike lane connecting Ontario's historic downtown and City Hall area to established residential communities.
45 The improvements made in the proposed project’s
vicinity will be on Vine Avenue (less than 0.1 mile west) and will be minor improvements within the City right-of-way to improve traffic and connectivity in the City. Anticipated construction activities could involve striping, painting, curb cuts, light and signage installation, street and sidewalk repairs, and landscaping. While construction of both projects may be simultaneous, all construction work for the proposed 413 West Emporia Street Live/Work Project would occur within the subject property and would not result in any street closures. Additionally, the proposed project would not involve changes to street lanes that would result in a substantial adverse cumulative impact to traffic when considered with the Vine Avenue and B Street Bike Boulevard Project.

Therefore, the proposed project would not contribute to substantial adverse cumulative impacts due to successive projects of the same type in the same place over time.

3.2 Significant Effect due to Unusual Circumstances

Section 15300.2(c) of the State CEQA Guidelines establishes that a categorical exemption shall not be used for an activity where there is a reasonable possibility that the activity would have a significant effect on the environment due to unusual circumstances. The project description includes design features, regulatory compliance, avoidance measures, and BMPs to ensure that construction and operation of the proposed project w ould not result in significant environmental effects.

The Housing Element of the Policy Plan states that “there are no environmental constraints limiting development potential” within the Downtown Housing Opportunity Area, in which the proposed project site is located. It states that “there are no known natural or man-made environmental development concerns that would require mitigation.” 46 As such, the record does
not indicate that there are any unusual environment circumstances or environmental constraints that would result in a significant effect on the environment. There are no ecologically sensitive areas, cultural resources, or hazardous materials that would render the site inappropriate for developing the land, consistent with the land use designations and zoning. There are no Habitat Conservation Plans (HCP) or Natural Community Preservation Plans (NCCP) that intersect the proposed project site.

Construction of the proposed project would occur during the nesting bird season, which generally occurs between February 1 and September 15. Design features have been included in the proposed project to avoid effects to nesting birds protected under the MBTA. The NWI was reviewed to identify the nearest wetlands to the proposed project site subject to protection under

413 West Emporia Street Live/Work Project Draft Memorandum for the Record May 22, 2023 Sapphos Environmental, Inc.

Section 404 of the Clean Water Act. Based on the desktop analysis and site visit, no wetlands as defined by Section 404 of the Clean Water Act are present within the boundaries of the proposed project site. The closest feature is approximately 1.75 miles east of the project site and is a concrete-lined channel classified as riverine habitat. The proposed project would be limited to work in previously developed areas on the existing paved lot and on the existing sidewalk within the public right-of-way, and it would not result in impacts to biological resources in relation to federally protected wetlands as defined by Section 404 of the Clean Water Act through direct removal, filling, hydrological interruption, or other means.

The proposed project includes tree removals but would result in no impacts to biological resources due to compliance with local tree preservation policies or ordinances. There is currently one shrub in the southwestern corner of the parcel, two trees in the center of the parcel, and four “parkway trees” on the sidewalk adjacent to the parcel. The proposed project includes the removal of the two trees on the parcel and two of the parkway trees as they pose a direct conflict with necessary construction operations. The parkway trees are owned by the City and can only be trimmed or removed by the City.
47 The City Department of Planning provides Landscape Design Guidelines that state that “a tree report shall be provided by a qualified landscape architect or certified arborist for trees on site proposed to be removed.”
48 Additionally, the Landscape Design Guidelines stipulate that replacement trees shall be specimen sized (60-inch or 48-inch box size), and two new trees must be planted for each removed, or as approved by the Landscape Planning Division. Consistent with the Landscape Design Guidelines, the proposed project applicant would ensure that a qualified landscape architect or certified arborist prepares and submits a tree report to the City, and the proposed project would plant 12 new trees, more than the minimum of 8 new trees required to replace the 4 removed trees at a 2:1 ratio.

In addition to the Landscape Design Guidelines, the City provides a list of measures that are required for tree protection during construction.
49 The two parkway trees that would be protected
in place would comply with these measures (please see Section 1.10, Construction Scenario, for the list of Project Design Features and Regulatory Compliance Measures). As a result, no significant impacts would occur to biological resources due to noncompliance with tree preservation policies or ordinances, and tree removals do not constitute an unusual environmental constraint.

Therefore, there are no unusual environmental circumstances or environmental constraints that preclude the proposed project from the use of a categorical exemption.

3.3 Scenic Highways

Section 15300.2(d) of the State CEQA Guidelines establishes that, not including improvements required as mitigation by an adopted negative declaration or certified EIR, a categorical exemption

shall not be used for a project that may result in damage to scenic resources including, but not limited to, trees, historic buildings, rock outcroppings, or similar resources, within a highway officially designated as a state scenic highway. The proposed project site is not within the viewshed of a designated state scenic highway. The nearest officially designated state scenic highway is State Route 91 in Orange County (approximately 14.7 miles southwest). 50 The nearest
eligible state scenic highway is State Route 142 (approximately 7.0 miles southwest). These state scenic highways do not have a view of the proposed project site due to intervening distance, development, and topography. Therefore, the construction, operation, and maintenance of the proposed project would have no significant impact on state scenic highways in the area.

3.4 Hazardous Waste Sites

Section 15300.2(e) of the State CEQA Guidelines establishes that a categorical exemption shall not be used for a project located on a site that is included on any list compiled pursuant to Section 65962.5 of the Government Code. Based on an Environmental Data Resources, Inc. (EDR) search of all available federal, state, and local government records and databases, no active mapped hazardous waste sites or cleanup sites are present on the proposed project site pursuant to Government Code Section 65962.5 (see Attachment 7 for a complete list of nearby hazardous waste sites records).

The EDR database report returned one inactive record from the HAZNET and the Hazardous Waste Tracking System (HWTS), which is the California Department of Toxic Substances Control’s (DTSC) data repository for hazardous waste manifest and ID Number information. A hazardous waste manifest is the shipping document that travels with hazardous waste from the point of generation, through transportation, to the final treatment, storage, and disposal facility.

The proposed project site was listed as the generator address in 2003 under generator ID CAC002571209 and all hazardous waste was transported and disposed off-site. This record has been determined to be “Inactive” by the HWTS, as it expired in 2004. 51 Therefore, the proposed
project site is not actively listed on any hazardous waste site or cleanup site list.

The EDR report searched the DTSC EnviroStor database, revealing no federal Superfund, state response, voluntary cleanup, school cleanup, evaluation, school investigation, military evaluation, tiered permit, or corrective action sites at the proposed project site . Additionally, the EDR report searched the State Water Resources Control Board’s GeoTracker database, revealing no leaking underground storage tank (LUST) cleanup sites, cleanup program sites, military cleanup sites, DTSC cleanup sites, waste discharge requirements (WDR) sites, permitted underground storage tanks (USTs), DTSC hazardous waste sites, land disposal sites, or oil/gas sites at the proposed project site. Therefore, the proposed project would not result in a significant impact on people or property from risks associated with hazardous waste sites.

3.5 Historical Resources

Section 15300.2(f) of the State CEQA Guidelines establishes that a categorical exemption shall not be used for a project that may cause a substantial adverse change in the significance of a historical resource.

1. A resource listed in, or determined to be eligible by the State Historical Resources Commission for listing in, the California Register of Historical Resources (CRHR) (Public Resources Code [PRC] § 5024.1, 14 California Code of Regulations [CCR] § 4850 et seq.).

2. A resource included in a local register of historical resources, as defined in PRC Section 5020.1(k), or identified as significant in an historical resource survey meeting the requirements of PRC Section 5024.1(g), shall be presumed to be historically or culturally significant. Public agencies must treat any such resource as significant unless the preponderance of evidence demonstrates that it is not historically or culturally significant.

3. Any object, building, structure, site, area, place, record, or manuscript that a lead agency determines to be historically significant or significant in the architectural, engineering, scientific, economic, agricultural, educational, social, political, military, or cultural annals of California may be considered to be an historical resource, provided the lead agency’s determination is supported by substantial evidence in light of the whole record. Generally, a resource shall be considered by the lead agency to be “historically significant” if the resource meets the criteria for listing in the CRHR (PRC § 5024.1, 14 CCR § 4852) including the following:

(a) Is associated with events that have made a significant contribution to the broad patterns of California’s history and cultural heritage; (b) Is associated with the lives of persons important in our past; (c) Embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of an important creative individual, or possesses high artistic values; or
(d) Has yielded, or may be likely to yield, information important in prehistory or history.

4. The fact that a resource is not listed in, or determined to be eligible for listing in, the CRHR, not included in a local register of historical resources (pursuant to PRC § 5020.1(k)), or identified in a historical resources survey (meeting the criteria in PRC § 5024.1(g)) does not preclude a lead agency from determining that the resource may be an historical resource as defined in PRC Sections 5020.1(j) or 5024.1.

The project site is not listed in, nor is it eligible to be listed in, the CRHR or the National Register of Historic Places (NRHP). The City of Ontario Historic Preservation Program indicates that any potentially historic local sites are listed in the California Historical Resources Inventory Database (CHRID), which does not include a listing for the subject property.

The project site consists entirely of a surface parking lot, with commercial spaces on either (east and west) side; non-historic residences on the facing (north) side of Emporia Street; and a railroad 583

track to its immediate south. As an undistinguished stretch of asphalt, the subject property contains no significant historical, architectural, or engineering resources.

413 West Emporia Street, which was the site of an approximately 40- by 40-foot garage in the 1952 Sanborn map, does not appear in any searches of historic newspapers. The site is not associated with events that have made a significant contribution to the broad patterns of California’s history and cultural heritage. Nor is it associated with the lives of persons important in our past. Since there is no building or other potential resource on the property, it does not embody the distinctive characteristics of any method of construction; nor does it represent the work of an important creative individual; nor does it possess high artistic values. Given the site disruption that occurred during the grading and paving of the site, it is not likely to yield information important in prehistory or history. Nor is the site known to have yielded any such information in the past.

The project site does not meet any of the criteria for designation in the NRHP, the CRHR, or any local designation. Since the proposed site does not constitute a historical resource, the proposed project would not result in a substantial adverse change in the significance of a historical resource.

4.0 CONCLUSION

Consistent with the provisions of Section 15332, Class 32, In-fill Development Projects , of the State CEQA Guidelines, the proposed project would construct an in-fill development project that:

(f) Is consistent with the applicable general plan designation and all applicable general plan policies as well as with applicable zoning designation and regulations. (g) Occurs within city limits on a project site of no more than 5 acres substantially surrounded by urban uses.
(h) Has no value as habitat for endangered, rare, or threatened species. (i) Would not result in any significant effects relating to traffic, noise, air quality, or water quality.
(j) Can be adequately served by all required utilities and public services.

The proposed project would not fall under any of the exceptions to the use of a categorical exemption as set forth in Section 15300.2 of the State CEQA Guidelines. Based on a literature and records review, supplemented by site visit, the proposed project site is not located in a sensitive environment; there are no cumulative impacts, unusual circumstances, or other limiting factors; the project site is not located within an officially designated state scenic highway corridor or on an active hazardous waste site; and the project would not cause a substantial adverse change in the significance of a historical resource that would make the exemption inapplicable based on the project records. Specific design measures as a part of the proposed project would ensure compliance with regulations and ensure that there would be no substantial adverse impacts. Based on substantial evidence generated from a literature and records review, modeling, and site investigation, none of the factors identified in Section 15300.2, Exceptions, of the State CEQA Guidelines make the categorical exemptions inapplicable.

1.0 INTRODUCTION

1.1 Purpose of this Study

The purpose of this Air Quality study is to de termine potential significant air quality impacts (if any) that may be created by construction, area or operational emissions (short term or long term) from the proposed Project. Should impacts be determined, the intent of this study would be to recommend suitable measures to bring those impacts to a level that would be considered less than significant.

1.2 Project Location

The proposed Ontario 9U residential development is located on an approximate 0.46-acre project site located at 413 W. Emporia Street having an Assessor Parcel Number (APN) of 1049-059-03 in the City of Ontario, CA. The project is generally located west of Euclid Avenue (SR-83) between State Street and Holt Boulevard. Euclid Avenue provides regional access to the project site via Interstate 10 (I-10) to the north and State Route 60 (SR-60) to the south.

The project site is surrounded by existing resi dential to the north across W. Emporia Street, existing commercial uses to the east and west, and the Union Pacific Railroad to the south, which services the Metrolink Riverside Line an d operates diesel-powered locomotives. The Ontario Station is located to the east across Euclid Avenue. A project vicinity map and location map are shown in Figure 1-A.

1.3 Project Description

The project proposes the construction of thre e 3-story live/work buildings consisting of 9 live/work units and surface parking. The units will consist of a ground floor studio and two upper floor bedrooms. The conceptual site plan is shown on Figure 1-B of this report. The proposed project land use will not require a zone change or General Plan amendment.

Construction would begin in early 2024 and be completed roughly six months later. Full operations are expected as early as 2024.

Based on discussions with the project applicant, since the project vicinity is adjacent to the Union Pacific Railroad, all residential homes co nstructed as part of this project will have mechanical ventilation filtration systems consistent with a Minimum Efficiency Reporting Value (MERV) rating of 16 installed as a design feature (California Energy Commission, 2019).

2.0 EXISTING ENVI RONMENTAL SETTING

2.1 Existing Setting

The existing Project site is cu rrently vacant. Adjacent surro unding land uses are mixed use with commercial and residential surrounding the Project site. The site topography is relatively flat onsite with elevations approximately 990 feet above mean sea level. The project site is located adjacent to the Union Pacific Rail Line to the south.

2.2 Climate and Meteorology

Climate within the SCAB area often varies dramatically over short geographical distances due to the size and topography. Most of southe rn California is dominated by high-pressure systems for much of the year, which keeps Hi ghland mostly sunny and warm. Typically, during the winter months, the high-pressure system drops to the south and brings cooler, moister weather from the north.

It is common for inversion layers to develop within high-pressure areas, which mostly define pressure patterns over the SCAB. These invers ions are caused when a thin layer of the atmosphere increases in temperature with height . An inversion acts like a lid preventing vertical mixing of air through convective overturning.

Daytime temperature highs within the City of Ontario typically range between 68 ºF in the winter to approximately 90 ºF in the summer with the month of August usually being the hottest month. Ontario usually receives an average seasonal precipitation of 15 inches of rain per year with the months of February and March usually being the wettest months of the year (City Data, 2022)

2.3 Regulatory Standards

2.3.1 Federal Standards and Definitions

The Federal Air Quality Standards were developed per the requirements of The Federal Clean Air Act, which is a federal law that was passed in 1970 and further amended in 1990. This law provides the basis for the national air pollution control effort. An important element of the act included the development of national ambient air quality standards (NAAQS) for major air pollutants. The Clean Air Act established two types of air quality standards otherwise known as primary and secondary standards.

Primary Standards set limits for the intention
of protecting public health, which includes sensitive populations such as asthmatics, children 603

5 Ldn Consulting, Inc. 4/18/23 22-25 Ontario 9U Air Quality and elderly. Secondary Standards set limits to protect publ ic welfare to include the protection against decreased visibility, damage to animals, crops, vegetation and buildings.

The EPA Office of Air Quality Planning and Standards (OAQPS) has set National Ambient Air Quality Standards for principal pollutants, wh ich are called "criteria" pollutants. These pollutants are defined below:

1. Carbon Monoxide (CO): is a colorless, odorless, and tasteless gas and is produced from the partial combustion of carbon-containing compo unds, notably in internal-combustion engines.

Carbon monoxide usually forms when there is a reduced availability of oxygen present during the combustion process. Exposure to CO near the levels of the ambient air quality standards can lead to fatigue, headaches, confusion, and dizziness. CO interferes with the blood's ability to carry oxygen.

2. Lead (Pb): is a potent neurotoxin that accumulates in soft tissues and bone over time. The major sources of lead emissions have historically been motor vehicles (such as cars and trucks) and industrial sources. Because lead is only slowly excreted, exposures to small amounts of lead from a variety of sources can accumulate to harmful levels. Effects from inhalation of lead near the level of the ambient air quality standard include impaired blood formation and nerve conduction. Lead can adversely affect the ne rvous, reproductive, digestive, immune, and blood-forming systems. Symptoms can include fatigue, anxiety, short-term memory loss, depression, weakness in the extremities, and learning disabilities in children.

3. Nitrogen Dioxide (NO 2): is a reactive, oxidizing gas capable of damaging cells lining the respiratory tract and is one of the nitrogen oxides emitted from high-temperature combustion, such as those occurring in trucks, cars, power plants, home heaters, and gas stoves. In the presence of other air contaminants, NO 2 is usually visible as a reddish-brown air layer over urban areas. NO 2 along with other traffic-related pollutants is associated with respiratory symptoms, respiratory illness and respiratory impairment. Studie s in animals have reported biochemical, structural, and cellular changes in the lung when exposed to NO2 above the level of the current state air quality standard. Clinical studies of human subjects suggest that NO 2 exposure to levels near the current standard ma y worsen the effect of allergens in allergic asthmatics, especially in children.

4. Particulate Matter (PM10 or PM2.5): is a complex mixture of tiny particles that consists of dry solid fragments, solid cores with liquid coatings, and small droplets of liquid. These particles vary in shape, size and chemical composition, and can be made up of multiple materials such as metal, soot, soil, and dust. PM10 particles are 10 microns (μm) or less and PM2.5 particles are

2.5 (μm) or less. These particles can contribute significantly to regional haze and reduction of visibility in California. Exposure to PM levels exceeding current air quality standards increases the risk of allergies such as asthma and respiratory illness.

5. Ozone (O 3): is a highly oxidative unstable gas capa ble of damaging the linings of the respiratory tract. This pollutant forms in the atmosphere through reactions between chemicals 604

6 Ldn Consulting, Inc. 4/18/23 22-25 Ontario 9U Air Quality directly emitted from vehicles, industrial plants , and many other sources. Exposure to ozone above ambient air quality standards can lead to human health effects such as lung inflammation, tissue damage and impaired lung functioning. Ozone can also damage materials such as rubber, fabrics and plastics.

6. Sulfur Dioxide (SO 2): is a gaseous compound of sulfur and oxygen and is formed when sulfur-containing fuel is burned by mobile sources, such as locomotives, ships, and off-road diesel equipment. SO 2 is also emitted from several industrial processes, such as petroleum refining and metal processing. Effects from SO2 exposures at levels near the one-hour standard include bronchoconstriction accompanied by symptoms, which may include wheezing, shortness of breath and chest tightness, espe cially during exercise or physical activity.

Children, the elderly, and people with asthma, cardiovascular disease or chronic lung disease (such as bronchitis or emphysema) are most susceptible to these symptoms. Continued exposure at elevated levels of SO2 results in increased incidence of pulmonary symptoms and disease, decreased pulmonary function, and increased risk of mortality.

2.3.2 State Standards and Definitions

The State of California Air Resources Board (ARB) sets the laws and regulations for air quality on the state level. The California Ambient Air Quality Standards (CAAQS) are either the same as or more restrictive then the NAAQS and also restrict four additional contaminants. Table

2.1 on the following page identifies both the NAAQS and CAAQS. The additional contaminants as regulated by the CAAQS are defined below:

1. Visibility Reducing Particles: Particles in the Air that obstruct the visibility.

2. Sulfates: are salts of Sulfuric Acid. Sulfates occur as microscopic particles (aerosols) resulting from fossil fuel and biomass combustion. They increase the acidity of the atmosphere and form acid rain.

3. Hydrogen Sulfide (H2S): is a colorless, toxic and flammable gas with a recognizable smell of rotten eggs or flatulence. H 2S occurs naturally in crude petroleum, natural gas, volcanic gases, and hot springs. Usually, H 2S is formed from bacterial breakdown of organic matter.

Exposure to low concentrations of hydrogen sulfide may cause irritation to the eyes, nose, or throat. It may also cause difficulty in breathin g for some asthmatics. Brief exposures to high concentrations of hydrogen sulfide (greater than 500 ppm) can cause a loss of consciousness and possibly death.

4. Vinyl Chloride: also known as chloroethene and is a toxic, carcinogenic, colorless gas with a sweet odor. It is an industrial chemical mainly used to produce its polymer, polyvinyl chloride (PVC).

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

2. National standards (other than ozone, particulate matter, and those based on annual arithmetic mean) are not to be exceeded more than once a year. The ozone standard is attained when the fourth highest 8-hour concentration measured at each si te in a year, averaged over three years, is equal to or less th an the standard. For PM10, the 24-hour standard is attained when the expected number of days per calendar year with a 24-hour average concentration above 150 µg/m3 is equal to or less than one. For PM2.5, the 24-hour standard is attained when 98 percent of the daily concentrations, averaged over three years, are equal to or less than the standard. Con tact the U.S. EPA for further clarification and current national policies.

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

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

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

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

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

8. On October 1, 2015, the national 8-hour ozone primary and secondary standards were lowered from 0.075 to 0.070 ppm.

9. On December 14, 2012, the national annual PM2.5 primary standard was lowered from 15 μg/m3 to 12.0 μg/m3 . The existing national 24- hour PM2.5 standards (primary and secondary) were retained at 35 μg/m3 , as was the annual secondary standard of 15 μg/m3 . The existing 24-hour PM10 standards (primary and secondary) of 150 μg/m3 also were retained. The form of the annual primary and secondary standards is the annual mean, averaged over 3 years.

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

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

12. The CARB has identified lead and vinyl chloride as 'toxic air co ntaminants' with no threshold le vel of exposure for adverse hea lth effects determined. These actions allow for the implementation of control measures at levels below the ambient concentrations specified for these pollutants.

13. The national standard for lead was revised on October 15, 2008 to a rolling 3-month average. The 1978 lead standard (1.5 μg/m3 as a quarterly average) remains in effect until one year after an area is designated for the 2008 standard, except that in areas designated nonattainment for the 1978 standard, the 1978 standard remains in effect until implementation plans to attain or maintain the 2008 standard are approved.

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

2.3.3 Regional Standards

The State of California has 35 sp ecific air districts, which are each responsible for ensuring that the criteria pollutants are below the NAAQS and CAAQS. Air basins that exceed either the NAAQS or the CAAQS for any criteria pollutants for designated periods defined in the footnote of Table 2.1 above are designated as “non-attainment areas” for that pollutant.

Currently, there are 15 non-attainment areas for the federal ozone standard and two non- attainment areas for the PM 2.5 standard. The state therefore created the California State Implementation Plan (SIP), which is design ed to provide control measures needed for California Air basins to attain ambient air quality standards.

The SCAQMD has jurisdiction over an area of approximately 10,743 square miles, consisting of the SCAB, and the Riverside County portions of the Salton Sea Air Basin (SSAB) and Mojave Desert Air Basin (MDAB). The district prepares Air Quality Management Plans (AQMP) to demonstrate how the region will reduce air pollution emissions to meet the federal and state health-based standards to comply with Clean Air Act requirements and will be ultimately a part of the SIP. Currently the SCAQMD is in the process of updating the latest adopted Air Quality Management Plan (signed December 7, 2012), and is expected to be signed mid to late 2016 (SCAQMD, 2016).

More specifically, the AQMP identifies the path South Coast Air Basin must take for the attainment of federal PM and ozone standards, and highlights the significant amount of reductions needed and the urgent need to engage in interagency coordinated planning to identify additional strategies, especially in the area of mobile sources, to meet all federal criteria pollutant standards within the timeframes allowed under the federal Clean Air Act.

The City of Ontario lies within the SCAB. The SCAQMD is the government agency, which regulates sources of air pollution within the City of Ontario. A complete listing of the current attainment status by pollutants for the SCAB is shown on Table 2.2.

2.4 California Environmental Qualit y Act (CEQA) Significance Thresholds

The California Environmental Quality Act has provid ed a checklist to identify the significance of air quality impacts. These guidelines are found in a 2018 updated Appendix G of the CEQA guidelines (California, 2018) :

AIR QUALITY -- Where available, the significance criteria established by the applicable air quality management or air pollution control district may be relied upon to make the following determinations. Would the Project:

A: Conflict with or obstruct implementation of the SCAQMD AQMP or applicable portions of the State Implementation Plan (SIP)?
B: Result in a cumulatively considerable net increase of any criteria pollutant for which the Project region is non-attainment under an applicable Federal or State ambient air quality standard.

C: Expose sensitive receptors (including, but no t limited to, schools, hospitals, resident care facilities, or day-care centers) to substantial pollutant concentrations? D: Result in other emissions (such as those leading to odors) adversely affecting a substantial number of people?

2.5 Air Quality Impact Assessment Screening Thresholds

To determine whether a project would create potential air quality impacts, the City of Ontario uses SCAQMD Air Quality Thresholds. The screening thresholds for construction and daily operations are shown in Table 2.3 below. Demonstrating a projects compliance with SCAQMD Screening thresholds are a significant part of demonstrating compliance with SCAQMDs AQMP and is critical to insuring less than significant impacts to questions A and B identified in section

2.4 above.

2.6 Local Air Quality

Criteria pollutants are measured continuously throughout the SCAB. This data is used to track ambient air quality patterns throughout the surrounding area. As mentioned earlier, this data is also used to determine attainment status when compared to the NAAQS and CAAQS. The SCAPCD is responsible for monitoring and reporting monitoring data. The district operates approximately 30 monitoring sites that collected data on criteria pollutants within the SCAB.

Ambient Data was obtained from the Upland Monitoring Station as reported by the California Environmental Protection Agency’s Air Resources Board Website (California Air Resources Board, 2021) and is shown in Table 2.4.

2.7 Localized Significance Thresholds

In June 2003 the SCAQMD proposed a methodology for calculating LSTs for NO 2, 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 ambi ent air quality standards (July 2008). (South Coast Air Quality Management District, 2008). The LST methodology is often utilized by most agencies governed under SCAQMD CEQA re view. SCAQMD developed mass rate look-up tables for projects to assist agencies with development of LSTs (SCAQMD, 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 NO 2 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/m 3. The LSTs derived by SCAQMD differentiated by Source Receptor area for which the proposed project is would be represented by SRA #32 within the northwest San Bernardino Valley area. The project was analyzed using the Project construction schedule with a 1-acre disturbed area. Table 2.5 below shows the worst case project LST at 25 meters (SCAQMD, 2009).

2.8 Offsite Health Risks

Health risk impacts are generally broken up into two various types (Type A and -B). Type A risks are generated from a new source to an existing receptor and Type B risks are whenever you place a new receptor in the vicinity of exis ting toxic sources like freeways or high traffic roads. Based on this information the proposed project is classified as Type B (Office of Environmental Health Hazard Assessment, 2015).

For Type A projects, significance thresholds for TACs have been established under SCAQMDs “Hot Spots” and permitting program (Rule 14 02). Under this program, excess cancer risk significance threshold is set at 10 in a million and acute and chronic, non-carcinogenic health effect, a hazard index of one mu st not be exceeded (SCAQMD, 2 019). If a risk is less than 10 in a million, no further health risk reporting requirements are necessary.

For Type B projects, there are no clear signif icance thresholds. California Environmental Quality Act (CEQA) statutes encourage an air dist rict or any lead agency to establish Type B significance thresholds under CEQA for any po llutant. While there ar e considerations that support the establishment of thresholds, there is no obligation to do so. Significance thresholds for Type B projects within the City of Ontario have also not been defined.

According to CAPCOA Air districts have histor ically recommended CEQA thresholds for air pollutants in the context of the air district’s clean air attainment plan, or (in the case of toxic air pollutants) within the framework of a rule or policy that manages risks and exposures due to toxic pollutants such as SCAQMD Rules 1401 and 1402 for Type A projects. For purposes of this analysis significance thresholds will be assumed to be 10 in a million exposed due to the effects of the close proximity to rail activity on Union Pacific UP Tracks south of the site.

3.0 METHODOLOGY

3.1 Construction Emissions Calculations

Air Quality impacts related to construction an d daily operations were calculated using the latest CalEEMod air quality model, which was developed by Breeze Software for SCAQMD in 2021. The County of Riverside recognizes the CalEEMod 2020.4.0 as the model of choice for projects of this nature.

The construction module in CalEEMod is used to calculate the emissions associated with the construction of the project. Construction emi ssions have several diff erent types of sources which contribute to emissions of pollutants. These source types include off-road equipment usage, on-road vehicle travel, fugitive dust, architectural coating, and paving off-gassing. The CalEEMod construction module also uses OFFROAD2011 for default emission rates for construction equipment. The CalEEMod input/output model is shown in Attachment A to
this report.

Fugitive dust calculations for grading within CalEEMod are based on methodologies described in Section 11.9, Western Surface Coal Mining, of the USEPA AP-42 which estimates the emission factor of PM10 applying a scaling factor to that of PM

15. Similarly, the emission factor
of PM2.5 is scaled from that of total suspended particulates (TSP). This methodology was adopted by SCAQMD as the preferred method for fugitive dust emissions calculations. This method utilizes maximum area method based on assumed disturbed grading areas.

Significant health risks or increased risks of cancerous and non-cancerous health problems can occur when sensitive rece ptors are exposed to Toxic Air Contaminants (TAC) for a significant quantity of time. Normally these impacts are analyzed over a period of 9, 30 or 70 years of continuous exposure or what is typically referred to as full lifetime and encompasses periods of potentially increased susceptibilit y to adverse health ef fects from chemical exposure, particularly during infancy, childhood and the later years of life. From a practical standpoint, chronic exposure for humans is considered to be greater than 12% of a lifetime of 70 years or at least 8 years in 70 (Office of Environmental Health Hazard Assessment, August 2003).

3.2 Construction Assumptions

The Project construction dates were estimated based on an estimated construction kickoff starting in early 2024 and be completed roughly 6 months later. Table 3.1 shows the expected timeframes for the construction processes as well as the expected number of pieces of equipment to complete the project. As a desi gn feature and to be consistent with SCAQMD 612

14 Ldn Consulting, Inc. 4/18/23 22-25 Ontario 9U Air Quality rule 403, the project will wet the site regularly to minimize fugitive dust emissions (SCAQMD, 2005).

3.3 Operational Emissions

Once construction is completed the proposed project would generate emissions from daily operations which would include sources such as Area, Energy, Mobile, Waste and Water uses, which are also calculated within CalEEMod. Area Sources include consumer products, landscaping and architectural coatings as part of regular maintenance. Energy sources would be from uses such as electricity and natural gas. Finally, mobile or transportation related emissions are calculated in CalEEMod through the use of EMFAC2017 and is also shown in Attachment A to this report.

In the EMFAC model, the emission rates are multiplied with vehicle activity data provided by the regional transportation agencies to calculate the statewide or regional emission inventories. An emission inventory is based on the emission rate (e.g., grams per pollutant emitted over a mile) and vehicle activity (e.g., miles driven per day).

Area sources originate from daily onsite uses, which require either burning fuel to generate energy (i.e. natural gas furnaces, gas water heaters and small engines) or the evaporation of 613

15 Ldn Consulting, Inc. 4/18/23 22-25 Ontario 9U Air Quality organic gases such as from paints (architectu ral coatings). Consumer product emissions are generated by a wide range of product catego ries, including air fr esheners, automotive products, household cleaners, and personal care products. Emissions associated with these products primarily depend on the increased population associated with residential development. It should be no ted that none of the proposed residential units will include a fireplace and was modeled as such.

3.4 Odor Impacts

Potential onsite odor generators would include short term construction odors from activities such as paving and possibly painting. The construction odors would be considered short term and would not be considered an impact. Given this the Project will not have a potential to create offensive odors and would therefore not be considered an impact under CEQA.

3.5 Health Risks Calculations and Methodology

The project site is located approximately 55 feet north of the Union Pacific Railroad which services the Metrolink Riverside Line. The pr oposed building is located 120 feet from the centerline of the roadway. The Southern Cali fornia Association of Governments (SCAG) prepared the “Comprehensive Regional Goods Movement Plan and Implementation Strategy” (SCAG, 2011) which provides estimates for 2035 intensity on rail lines in Southern California.

Rail activities adjacent to the proposed Projec t would have a capacity to have as many as three (3) Amtrack passenger trains, 20 metro link passenger trains and up to 30 freight trains daily in 2035 or as many as 53 trains daily. Fr eight trains typically have an average of two locomotives and passenger trains typically have one locomotive in the area adjacent to the Project. Locomotives also range in powe r but are generally between 2,500 and 5,000 horsepower. For this assessment, it’s assumed as many as 23 locomotives would be used for passenger trains and 60 locomotives would be used for freight trains or a total of 83 locomotives daily and an average of 4,000 horsepower.

Emission rates vary for each locomotive and locomotive technology is continuously improving.

The Environmental Protection Agency (EPA) has established emission standards for oxides of nitrogen (NOx), hydrocarbons (HC), carbon monoxide (CO), particulate matter (PM) and smoke for newly manufactured and remanufactured locomotives. These standards, which are codified at 40 CFR part 1033, include severa l sets of emission standards with applicability dependent on the date a locomotive is first manufactured. The first set of standards (Tier 0) applies to most locomotives originally manufactured before 2001. The most stringent set of standards (Tier 4) applies to locomotives or iginally manufactured in 2015 and later (EPA, 2009). These standards are shown in Table 3. 2 below. Using this data and the weighted 614

16 Ldn Consulting, Inc. 4/18/23 22-25 Ontario 9U Air Quality averaging approach considering the fleet population breakdown as shown in Figure 3-A an average PM10 emission factor for locomotive exhaust would be 0.168 g/bhp-hr.

17 Ldn Consulting, Inc. 4/18/23 22-25 Ontario 9U Air Quality As noted in Section 3.1, Cancer risk calculations are based on a 70-year lifetime exposure.

For purposes of modeling, AERM OD was used for air quality dispersion modeling and is the preferred/recommended U.S. Environmental Protection Agency (EPA) model for line sources like railways and roadways. The software has the ability to incorporate meteorological inputs as well as multiple source and receptor loca tions and is now used throughout the world.

AERMOD inputs are based on an average train speed of 35 mile per hour and a load factor of

0.48 (Port of Long Beach, 2022). Based on this, the rail line would on average generate a daily emission of 0.00745 gram/second adjacent to the site. The calculation breakdown is provided in Attachment B to this report.

A graphical representation of the modeling locations is shown on a site aerial in Figure 3-B on the following page. The graphic depicts the discreet receptors (1 through -3) which are placed at the building façade adjacent to the adjacent rail line. Modeling for the rail is represented by multiple volume sources used by AERMOD to calculate roadway emissions and are identified as red squares, the black grid repres ents a receptor matrix made up of computer- generated receptors used by AERMOD to calculate emission values for contour and discreet outputs. The AERMOD model input/output is shown in
Attachment C to this report.

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 k ilogram body weight pe r day (mg/kg/d). For residential exposure, the breathing rates are determined for specific age groups, so inhalation dose (Dose-air) 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 norma lized 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)

19 Ldn Consulting, Inc. 4/18/23 22-25 Ontario 9U Air Quality 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 a 70-year lifespan of exposure. For example, an inhalation cancer risk of 5 x 10-6 is the same as stating that an individual has an estimate d 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)

4.2 Operational Findings

Once construction is completed the proposed project would generate air quality emissions from daily operations which are calculated within CalEEMod. Based on the input parameters identified in Section 3.2 of this report, no operational impacts would be expected. Operational emissions are shown in Table 4.2 on the following page.

4.3 Localized Significance Thresholds for Construction

SCAQMD also recommends using LST methodol ogy which incorporates background ambient air quality data. Based on the recommended methodologies, mobile offsite emission should not be included. Table 4.3 on the following page shows the modeled estimates for both construction and operations excluding offsite mobile emissions. Furthermore, the worst case LST is at 25 meters from the project centroid and will be utilized for this project. Since this is worst case, if the project complies at 25 meters , it will comply at all locations beyond this distance. Based on the modeling results, no LST impacts are expected.

Since no direct operation on construction impacts are expected, the proposed project would be consistent with the SIP and local AQMP. Gi ven this, less than significant cumulative operational impacts would be expected.

4.4 Odor Impact Findings

Odor impacts from construction operations would be considered short term events and would not be considered an impact. Long term operations will not create offensive odors and would not create any operational odor impacts.

4.5 Health Risk Findings

A graphical representation of the modeling outputs from AERMOD is shown on a site aerial in Figure 4-A below. These results include the proposed MERV 16 filtration systems and are required as a condition to this project since modeling assumes these design features included in the Project Description.

The EPA indicates that MERV 16 filtration systems can reduce PM 10 by 95% (EPA, 2023).

Based on modeling, it was found that MERV 16 ventilation systems would adequately reduce diesel particulate matter to a level considered less than significant from trucks along the rail tracks to the south. These assumptions were included within health risk modeling and a summary from outputs are shown in Table 4.4 below. It was found that DPM concentrations were less at the second and third levels of the structure and would also be less than significant with MERV 16 filtration.

The results of the cancer risk calculations account for heating and ventilation air filtration and are shown in Table 4.4. Detailed calculations are also provided in Attachment D to this report. These locations would be best described as the inside of the building with MERV 16 indoor air filtration. Based on these calculations, cancer risks would not exceed Level A significance thresholds of 10 per one million exposed and would be less than significant. Based on modeling, floors 2 and -3 have a lower expected emission concentration than the first floor and would also have a slightly lower cancer ri sk. Based on this, health risks on the second and third floors would be less than significant.

4.6 Conclusion of Findings

During construction of the proposed Project, fugitive dust emissions would be expected but would not exceed thresholds established by the SCAQMD. Given this, no construction mitigation will be required.

Additionally, emissions will be generated from op erational sources once the project is fully operational in 2024 though no air quality impacts would be expected. The project was analyzed under localized significance thresholds for both construction and operations and was found to generate less than significant impacts.

Health risk impacts are generally broken up into two various types (Type A and -B). Type A risks are generated from a new source to an existing receptor and Type B risks are whenever you place a new receptor in the vicinity of exis ting toxic sources like freeways or high traffic roads. Based on this information the proposed project is classified as Type B (Office of Environmental Health Hazard Assessment, 2015). It was found that rail activities adjacent to the site would generate less than significant health risk impacts. It should be noted again thought that because this analysis assumes MERV 16 air filtration systems would be installed within each unit, this would be a requirement for the Project.

623

25 Ldn Consulting, Inc. 4/18/23 22-25 Ontario 9U Air Quality

The proposed Project would not be expected to generate offensive odors and would therefore not impact any sensitive receptors.

Finally, the project does not seek a rezone and has been constructed to be compatible with the City of Ontario’s general plan. Based on this, no cumulative impa cts would be expected for air quality.

2 Preliminary Water Quality Management Plan (PW QMP)

1. Introduction
The
Preliminary Water Quality Management Plan (PWQMP) is a planning tool to improve integration of required water quality elements, stormwater management, water conservation, rainwater harvesting and re-use, and flood management in land use planning and the City’s development process. The Preliminary WQMP will assist project applicants and planners in properly designing and laying out project sites so that water quality may be incorporated in the most effective manner and at the lowest cost for the developer.

The San Bernardino County Municipal Separate Storm Sewer System Permit (MS4 Permit) requires project-specific Water Quality Management plans (WQMP) to be prepared for all priority new development and significant redevelopment projects listed in Section 2 of this document. The MS4 Permit stipulates that the City of Ontario require priority project applicants to submit a Preliminary project-specific WQMP, as early as possible, during the environmental review or planning phase of a development project and that the Preliminary WQMP be approved prior to the issuance of land use entitlement.

2. Priority Projects (requiring a Preliminary WQMP)
Land
Use entitlement shall not be issued for any of the listed projects, below, until a Preliminary WQMP has been approved by the City’s Engineering Department. For construction projects not going through entitlement, a Preliminary and Final project-specific WQMP shall be approved, prior to the issuance of construction permits:

Check the appropriate project category below, for this project:

Check
belo
w Project Categories

1. All significant re-development projects. Significant re-development is defined as the addition or replacement of 5,000 or more square feet of impervious surface on an already developed site subject to discretionary approval of the Permittee. Redevelopment does not include routine maintenance activities that are conducted to maintain original line and grade, hydraulic capacity, original purpose of the facility, or emergency redevelopment activity required to protect public health and safety. Where redevelopment results in an increase of less than fifty percent of the impervious surfaces of a previously existing developed site, and the existing development was not subject to WQMP requirements, the numeric sizing criteria discussed below applies only to the addition or replacement, and not to the entire developed site. Where redevelopment results in an increase of fifty percent or more of the impervious surfaces of a previously existing developed site, the numeric sizing criteria applies to the entire development (new and existing).
708

below P roject Categories

2. New development projects that create 10,000 square feet or more of impervious surface (collectively over the entire project site) including commercial, industrial, residential housing subdivisions (i.e., detached single family home subdivisions, multi-family attached subdivisions or townhomes, condominiums, apartments, etc.), mixed-use, and public projects. This category includes development projects on public and private land, which fall under the planning and building authority of the permitting agency.

3. Auto motive repair shops (with SIC codes 5013, 5014, 5541, 7532- 7534, 7536-7539).

4. Res taurants and Food Service Establishments where the land area of development is 5,000 square feet or more.

5. Dev
elopments of 2,500 square feet of impervious surface or more adjacent to (within 200 feet) or discharging directly into environmentally sensitive areas (ESA’s) such as areas designated in the Ocean Plan as areas of special biological significance or waterbodies listed on the CWA Section 303(d) list of impaired waters.

6. Par
king lots of 5,000 square feet or more exposed to storm water. Parking lot is defined as land area or facility for the temporary storage of motor vehicles.

7. Reta il Gasoline Outlets (RGOs) that are either 5,000 sq ft or more, or have a projected average daily traffic of 100 or more vehicles per day.

8. *This project is not covered under any of the categories listed above. * If t
he development is not covered under any of the project categories listed in Section 2, the project is not required to design and install Site Design/LID BMPs or Treatment Control BMPs to treat the design storm event (Design Capture Volume) described in Section 4.

3. Pr e
liminary WQMP Objectives
Throu
gh a combination of Site Design/LID BMPs (where feasible), Source Control, and/or Treatment Control BMPs, project-specific WQMPs shall address all identified pollutants and hydrologic conditions of concern from new development and significant re-development projects for the categories of projects (priority projects) listed in Section 2. Under each type of BMP, listed below, please indicate which BMPs are planned to be implemented and included in the Final WQMP for the project:

A. Site Design/LID (Low Impact Design) for Reducing Stormwater Runoff:

The MS4 Permit requires each priority development project to infiltrate, harvest and use, evapotranspire, or bio-treat the runoff from a 2-yr, 24-hour storm event (Design Capture Volume). If site conditions do not permit infiltration, harvest and use, evapotranspiration, and/or bio-treatment of the entire Design Capture Volume, at the project site, Site Design/LID techniques are required to be implemented to the Maximum Extent Practicable, at the project site, and the remainder of the DCV shall be infiltrated, harvested, bio-treated or treated by alternative measures.
709
4 Project applicants shall submit a Preliminary WQMP that documents the LID/Site Design BMPs, proposed for the project. Please indicate, in the table below, which Site Design/LID BMPs will be utilized on this project to accomplish this requirement:

Planned
Provide at least the minimum effective area required for LID BMPs, to comply with the WQMP (see Table 3-1 below).

Grade parking lot areas/drive aisles/roof drains to sheet flow runoff into landscaped swales, via curb cuts or zero-face curbs or otherwise disconnect direct drainage from MS4.

Design landscaped areas as swales and grade to accept
runoff from building roofs, parking lots and project roadways.

Install surface retention basins or infiltration trenches to receive impervious area runoff.

Install pervious pavement in parking stalls, alleys, driveways, gutters, walkways, trails or patios.

Install underground stormwater retention chambers where downstream landscaped areas are limited.

711
6 4. Volume-based calculation (approximate) for sizing on-site or off-site Stormwater Retention/Infiltration, Harvest & Re-Use or Biotreatment facilities 1) Calculate the “Watershed Imperviousness Ratio”, i, which is equal to the percent of impervious area in the BMP Drainage Area divided by 100. 2) Calculate the composite runoff coefficient C BMP for the Drainage Area above using the foll
owing equation:

CBMP = 0.858i
3 – 0.78i
2 + 0.774i + 0.04
where
: CBMP = composite runoff coefficient; and,
i = w
atershed imperviousness ratio.
3) Determine the area-averaged “6-hour Mean Storm Rainfall”, P 6, for the Drainage Area.

This
is calculated by multiplying the area averaged 2-year 1-hour value (0.55”-0.6”) by the appropriate regression coefficient from Table 1 (1.4807). The 2-yr, 1-hr value for southern Ontario is approximately to 0.5” (P 6 = 0.5*1.4807 = 0.74 and northern Ontario is a
pproximately 0.6” in/hr (P6 = 0.6*1.4807 = 0.89).
4) De
termine the appropriate drawdown time. Use the regression constant a = 1.582 for 24 hours and a = 1.963 for 48 hours. Note: Regression constants are provided for both 24 hour and 48 hour drawdown times; however, 48 hour drawdown times should be used in most areas of California. Drawdown times in excess of 48 hours should be used with caution as vector breeding can be a problem after water has stood in excess of 72 hours. (Use of the 24 hour drawdown time should be limited to drainage areas with coarse soils (Class ‘A’ soils, that readily drain.) 5) Calculate the “Maximized Detention Volume”, P 0, using the following equation:

P0 = a · CBMP · P6
where: P0 = Maximized Detention Volume, in inches
a = 1
.582 for 24 hour and a = 1.963 for 48 hour drawdown,
CBMP = composite runoff coefficient; and,
P6 = 6-hour Mean Storm Rainfall, in inches
6) Ca
lculate the “Target Capture Volume”, V 0, using the following equation:

V0 = (P0 · A) / 12
wher
e: V0 = Target Capture Volume, in acre-feet
P0 = Maximized Detention Volume, in inches; and,
A =
BMP Drainage Area, in acres

5. Hydrol
ogic Conditions of Concern (HCOC) and use of the on-line San Bernardino County HCOC Map for determining necessary mitigation steps necessary if there are HCOCs downstream of a project:

Project applicants may access the on-line HCOC Map at:
http://sbcounty.permitrack.com/WAP/ . The map will indicate any hydrology concerns with downstream waterways that are hydraulically connected to the project and will indicate if there are any approved regional projects downstream that could be utilized for off-site mitigation of HCOCs. Please indicate here if the project will or will not be able to retain/infilter, harvest and use or biotreat and detain the DCV, on-site, as calculated in Section 4 and if there are HCOCs identified downstream of the project:

Retain or Harvest/Use the DCV on site? Yes No
Biotreat the DCV but not infilter the runoff? Yes No
HCOCs identified downstream of site? Yes No
If the
entire DCV will not be retained on site, the DCV is biotreated but not infiltered or additional detention capacity is needed to address identified HCOCs, downstream of the site, please list here, what additional mitigation measures will be utilized (on-site or off-site) to address HCOCs (see Section 4.2.1-4.2.3 of the SB County WQMP Technical Guidance):

1 Precipitation frequency (PF) estimates in this table are based on frequency analysis of partial duration series (PDS).

Numbers in parenthesis are PF estimates at lower and upper bounds of the 90% confidence interval. The probability that precipitation frequency estimates (for a given duration and average recurrence interval) will be greater than the upper bound (or less than the lower bound) is 5%. Estimates at upper bounds are not checked against probable maximum precipitation (PMP) estimates and may be higher than currently valid PMP values.

Please refer to NOAA Atlas 14 document for more information.

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 (L max): 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 communi ty 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 band- edge 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. 726

EXECUTIVE SUMMARY

This noise study has been comple ted to determine the noise impacts to and from the proposed multi-family residential project. The project proposes the construction of a 3-story multi-family residential building consisting of 9 apartment units. The project is located at 413 W. Emporia Street (APN: 1049-059-03), in the City of Ontario within the County of San Bernardino.

Construction Noise

Project construction noise levels are considered exempt if activities occur within the hours specified in the City of Ontario Municipal Co de, Section 5-29.09 of 7:00 a.m. and 6:00 p.m., Monday through Friday, or 9:00 a.m. and 6:00 p.m., Saturday and Sunday unless approval is obtained from the City Building Official or City Engineer.

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.

Operational Noise

Based upon the property line noise levels determined in the analysis, none of the proposed noise sources directly or cumulatively exceeds the Ci ty’s property line standa rds at the residential property line to the north across W. Emporia Street. Therefore, the proposed developments related operational noise levels comply with the noise standards at the property lines. No Impacts are anticipated and no mitigation is required.

Transportation Noise Levels – Onsite

The noise levels determined for the train and airp ort activities were combined to determine the overall cumulative noise levels at the proposed outdoor use areas. As determined, the proposed outdoor use areas will be exposed to train noise levels of 58 dBA CNEL and aircraft noise levels of 64 dBA CNEL. The resultant cumulative noise levels from the train and airport activities were calculated to be 65 dBA CNEL and therefore would comply with the City of Ontario Noise standards of 65 dBA CNEL at the multi-family residences and outdoor useable areas.

Additionally, the project would be required to meet the City’s established interior noise limit of 45 dBA CNEL. To meet the interior noise limit of 45 dBA CNEL, all glass assemblies should have a minimum Sound Transmission Class (STC) rating of 28 or better. Exterior entry doors should be of solid core construction with a minimum STC rating of 28 or better.

1.0 PROJECT INTRODUCTION

1.1 Purpose of this Study

The purpose of this Noise study is to determine noise impacts, if any, to the Project from off-site sources (i.e., traffic) and from the project (i.e., construction, operational) onto surrounding uses.

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 proposed Ontario 9U residential development is located on an approximate 0.46-acre project site located at 413 W. Emporia Street having an Assessor Parcel Number (APN) of 1049-059-03 in the City of Ontario, CA. The project is generally located west of Euclid Avenue (SR-83) between State Street and Holt Boulevard. Euclid Avenue provides regional access to the project site via Interstate 10 (I-10) to the north and State Rout e 60 (SR-60) to the south. The project site is surrounded by existing residential to the north across W. Emporia Street, existing commercial uses to the east and west, and the Union Paci fic Railroad to the south, which services the Metrolink Riverside Line and operates diesel-powered locomotives. The Ontario Station is located to the east across Euclid Avenue. A project vicinity map is shown in Figure 1-A.

1.3 Project Description and Purpose

The project proposes the construction of a 3-stor y multi-family residential building consisting of 9 apartment units and surface pa rking. The units will consist of two and three-bedroom floor plans. The conceptual site plan is shown on Figure 1-B of this report. 728

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 U.S. Environmental Protection Agency (U.S . EPA) has compiled da ta 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. 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 a ll of these methods may be required to reduce noise levels to an acceptable level.

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.
731
5 Ldn Consulting, Inc. 3/23/22 22-25 Ontario 9U Noise
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 (m easured 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 affect s perception. Typical construction vibrations fall in the 10 to 30 Hz range and usually occurring ar ound 15 Hz. Traffic vibrations exhibit a similar range of frequencies; however, due to their susp ension systems, it is less common, to measure traffic frequencies above 30 Hz.

Propagation of ground-borne vibrations is comp licated 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 with distance as a result of material damping in the form of internal fr iction, 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

To limit population exposure to physically and/or psychologically damaging as well as intrusive noise levels, the federal government, the State of California, various county governments, and most municipalities in the state have establishe d standards and ordinances to control noise.

Roadway, Air and rail traffic, and commercial and industrial activities are typically the major sources of noise in some areas. Federal, state, and local agencies regulate different aspects of environmental noise. Federal and state agencies generally set noise standards for mobile sources such as aircraft and motor vehi cles. Local agencies generally se t noise standards or regulations of stationary sources.

3.1 Federal

Federal Transit Administration (FTA)

No federal regulations apply to noise or vibrat ion from the proposed project, but the United States Department of Transportation Federal Transit Administration (FTA) provides criteria for acceptable levels of groundborne vibration for various types of special buildings that are sensitive to vibration (Federal Transit Administration, 2018). For purposes of identifying potential project- related vibration impacts, the FTA criteria will be used. The human reaction to various levels of vibration is highly subjective. The upper end of the range shown for the threshold of perception, or roughly 65 VdB, may be considered annoying by some people. Vibration below 65 VdB may also cause secondary audible effects, such as a slight rattling of doors, suspended ceilings/fixtures, windows, and dishes, any of which may result in additional annoyance. Table 3-1 on the following page, shows the FTA groundborne vibration and noise impact criteria for human annoyance.

In addition to the vibration annoyance standards presented above, the FTA also applies the following standards for construction vibration da mage. As shown in Table 3-2 on the following page, structural damage is possible for typical residential construction when the peak particle velocity (PPV) exceeds 0.2 inch per second (in/sec). This criterion is the threshold at which there is a risk of damage to normal dwellings.

In the context of this analysis, the noise and vi bration impacts associated with the construction operations will be conditioned to comply with the thresholds stat ed above. The potential noise and vibration impacts are analyzed separately below.

1 “Frequent Events” are defined as more than 70 vibration events per day. Most rapid transit projects fall into this category. 2 “Occasional Events” are defined as between 30 and 70 vibration events of the same source per day. Most commuter truck lines have this many operations.
3 “Infrequent Events” are defined as fewer than 30 vibration events of the same kind per day. This category includes most commuter rail branch lines
4 This criterion limit is based on levels that are acceptable for most moderately sensitive equipment such as optical microscopes.

Vibration-sensitive manufacturing or research will require detailed evaluation to define the acceptable vibration levels. Ensuring lower vibration levels in a building often requires special design of the HVAC systems and stiffened floors. 5 Vibration-sensitive equipment is not sensitive to groundborne noise.

3.2 State of California

Community Noise Assessment Criteria

The following significance criteria are based on guidance provided by Appendix G of the California Environmental Quality Act (CEQA) Guidelines. For the purposes of this report, noise impacts would be potentially significant if the proposed Project is determined to result in or cause:

• Exposure of persons to or generation of noise levels in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies; • A substantial permanent increase in ambient noise levels in the Project vicinity above existing levels without the proposed Project; or
• A substantial temporary or periodic increase in ambient noise levels in the Project vicinity above noise levels existing without the proposed Project.

While the CEQA Guidelines and City of Ontari o noise standards provide direction on noise compatibility and establish noise standards by land use type, they do not define the levels at which increases above the ambient noise levels are considered substantial. However, the Federal Highway Administration and Caltrans both identify changes in noise levels of greater than 3 dBA as "barely perceptible," while changes of 5 dBA are considered "readily perceptible.” This is consistent with the community response to noise characteristics described in Section 3.3 below.

In a community situation, the noise exposure is extended over a long time period, and changes in noise levels occur over year s rather than the immediate comparison made in a laboratory situation. The level at which changes in communi ty noise levels become discernible is likely to be some value greater than 1 dBA, and 3 dBA appears to be appropriate for most people. On this basis, and for the purposes of this study, a substantial increase in noise levels attributable to operations of the Project would occur if:

1. Ambient conditions are below applicable st andards, and project-generated noise at receptor land uses would result in:

• An exceedance of the suggest ed land uses/noise compatibility guidelines for surface transportation sources presented in the City of Ontario Noise Element (mobile sources); or
• An exceedance of the exterior noise standards defined in the City of Ontario Noise Ordinance (area/stationary sources);

736
10 Ldn Consulting, Inc. 3/23/22 22-25 Ontario 9U Noise

2. If ambient noise conditions exceed applicable Noise Ordinance Standards and project- generated noise would create a “barely perceptible” 3 dBA or greater permanent increase in ambient exterior noise levels.

3. For construction noise, a substantial increase in noise would occur if project-related construction activities occur of on any week day outside the hours of 7:00 a.m. and 6:00 p.m. or on Saturday or Sunday outside the hours of 9:00 a.m. and 6:00 p.m.

California Building Standards Code

The California Building Standards Code is cont ained in Title 24 of the California Code of Regulations and consists of 11 different part s that set various construction and building requirements. Part 2, California Building Code , Section 1207, Sound Transmission, establishes sound transmission standards for interior wa lls, partitions, and floor/ceiling assemblies.

Specifically, Section 1207.4 establishes that interior noise levels attributable to exterior noise sources shall not exceed 45 dBA DNL or CNEL (as set by the local General Plan) in any habitable room.

Caltrans

The California Department of Transportation’s (Caltrans) Transportation and Construction Vibration Guidance Manual provides a summary of vibration criteria that have been reported by researchers, organizations, and governmental agencies (Caltrans, 2020). Chapters Six and Seven of this manual summarize vibration detection and annoyance criteria from various agencies and provide Caltrans recommended guidelines and thresholds for evaluating potential vibration impacts on buildings and humans from transportation and construction projects. These thresholds are summarized in Table 3-3 and Table 3-4.

3.3 Local Regulations

The City of Ontario General Plan and Municipal Code establishes the following applicable policies related to noise and vibration.

City of Ontario General Plan Noise Element

The Noise Element includes stan dards for land use compatibility for community noise exposure.

The Ontario Plan (City of Ontario, 2009) standa rds are derived from standards contained in the General Plan Guidelines, a publication of the California Office of Planning and Research. These standards are used by many California cities and counties.

The Noise Element specifies the maximum noise levels allowable for new developments impacted by transportation noise sources such as arterial roads, freeways, airports and railroads. For the purposes of this project, the noise impacts associated with traffic are controlled by the Ontario Plan Noise Element. For noise sensitive residential areas, the exterior noise levels should remain below 65 dBA CNEL, and the interior noise levels should remain below 45 dBA CNEL.

City of Ontario Municipal Code

Section 5-29.04 (a) of the City of Ontario Noise Ordinance (City of Ontario Municipal Code, 2021) states, as shown in Table 3-5 below, “the following exterior noise standards, unless otherwise specifically indicated, shall apply to all properties within a designated noise zone.

4.0 ENVIRONMENTAL SETTING S & EXISTING CONDITIONS

4.1 Settings & Locations

According to The Ontario Plan Zoning and Land Use Plan, the project is located within the Downtown Mixed-Use (MU-1) zoning district. The MU-1 zoning district is established to accommodate a fairly intensive mixture of vertic al and horizontal retail and office uses at a development intensity of up to 2.0 FAR, and residential uses at a density of 25 to 75 DU/AC.

Development projects are intended to maintain a pedestrian friendly at mosphere, while at the same time enhancing the historic character of the area. The most intensive uses are envisioned along Euclid Avenue and Holt Boulevard. The MU-1 zoning district is consistent with and implements the Downtown Mixed Use Area land use designation of the Policy Plan component of The Ontario Plan.

The surrounding land uses are also zoned MU-1 with commercial uses to the east and west and existing multi-family residences to the north of W. Emporia Street. The project site is adjacent to the Union Pacific Railroad to the south which prov ides service for the Me trolink Riverside Line.

The Metrolink Ontario Station is located to the east of Euclid Avenue.

4.2 Existing Noise Conditions

The project is adjacent to the Un ion Pacific Railroad to the south. Existing commercial uses are located adjacent to the project to the east and west and existing multi-family residences across W.

Emporia Street to the north.

4.3 Noise Measuring Methodology and Procedures

Long-term 24-hour measurements were taken at the project site having a relatively flat terrain and no obstruction from trees or structures. The no ise measurements were recorded on Wednesday February 16th to Thursday February 17th, 2022 by Ldn Consulting between approximately 1:00 p.m. and 1:00 p.m. the following day. Noise measurements were taken using a Larson-Davis Spark Model 706 Type 2 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.

Table 4-1 provides the hourly noise levels alon g with the average and CNEL values. The noise measurement locations were determined based on site access and noise impact potential to the proposed sensitive uses. Long-term monitoring location 1 (LT-1) was located at the northern portion of the project site. The noise monitoring locations are provided graphically in Figure 4-A. 742

5.0 RECEIVER LOCATIONS

To assess the potential for long-term operational and short-term construction and operational noise impacts, the following sensitive receiver locations, as identified below, was identified as representative locations for analysis. Sensitive receivers are generally defined as locations where people reside or where the presence of unwanted sound could otherwise adversely affect the use of the land. Noise-sensitive land uses are generally considered to include schools, hospitals, single- family dwellings, mobile home parks, churches, libraries, and recreation areas. Moderately noise- sensitive land uses typically include multi-family dwellings, hotels, motels, dormitories, out-patient clinics, cemeteries, golf courses, country clubs, athletic/tennis clubs, and equestrian clubs. Land uses that are considered relatively insensitive to noise include business, commercial, and professional developments. Land uses that are typically not affected by noise include: industrial, manufacturing, utilities, agriculture, undeveloped land, parking lots, warehousing, liquid and solid waste facilities, salvage yards, and transit terminals.

Receiver locations are located in outdoor living areas (e.g., backyards) at 10 feet from any existing or proposed barriers or at the building façade, whichever is closer to the Project site, based on FHWA guidance, and consistent with additional guidance provided by Caltrans and the FTA, as previously described in Section 3. Sensitive receiver locations in the Project study area include the residential uses along the length of the northern property line as described below. Other sensitive land uses in the Project study area that are located at greater distances than those identified in this noise study will experience lower noise levels than those presented in this report due to the additional attenuation from distance and the shielding of intervening structures. Distance is measured in a straight line from the project boundary to each receiver location.

R1: Located across W. Emporia Street, R1 represents the existing residential homes north of the project site. This location was chosen based on the relation to the center of the proposed project site.

6.0 CONSTRUCTION NOISE

6.1 Construction Noise Prediction 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 da ta 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.

The project site is generally flat with no existi ng structures on site. Therefore, no significant grading activities are anticipated. Grading activities would be limited to minor grade adjustments required for the preparation of paving activities for the internal parking areas and drive aisles.

6.2 Potential Construction Noise Impact

Project construction noise levels are considered exempt if activities occur within the hours specified in the City of Ontario Municipal Co de, Section 5-29.09 of 7:00 a.m. and 6:00 p.m., Monday through Friday, or 9:00 a.m. and 6:00 p.m., Saturday and Sunday unless approval is obtained from the City Building Official or City Engineer.

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.

6.3 Construction Vibration Findings and Mitigation

Construction activity can result in varying degrees of ground 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. To control short-term construction vibration related impacts, the City of Ontario has established “steady state” or long- 747
21 Ldn Consulting, Inc. 3/23/22 22-25 Ontario 9U Noise term vibration standards which are presented in Section 3.3. The vibration impacts associated with the operation of the proposed project construction equipment are considered short-term and will not present a long-term vibration impact.

According to the Transportation and Construction -Induced Vibration Guidance Manual prepared for Caltrans, ground-borne vibration from construction activities and equipment such as such as D-8 and D-9 Caterpillars bulldozers, earthmovers and haul trucks at distances of 10 feet do not create vibration amplitudes that causes structural damage to nearby structures. Since the proposed project is not expected to employ any pile driving or rock blasting equipment and with the nearest receivers located over 50 feet from the nearest point of construction activities, impacts from groundborne vibration are anticipated to be less-than-significant.

In addition to the construction related activities, operational activities at the proposed project site will not include nor require equipment, facilities, or activities that would result in perceptible ground borne vibration, thus creating no ground borne vibration impacts. 748

7.0 OPERATIONAL NOISE

7.1 Potential Noise Impacts

This section examines the potential stationar y noise source impacts associated with the development and operation of the proposed project. According to The Ontario Plan Zoning and Land Use Plan, the project is located within the Downtown Mixed-Use (MU-1) zoning district. The MU-1 zoning district is established to accommod ate a fairly intensive mixture of vertical and horizontal retail and office uses at a development intensity of up to 2.0 FAR, and residential uses at a density of 25 to 75 DU/AC. Development pr ojects are intended to maintain a pedestrian friendly atmosphere, while at the same time enhancing the historic character of the area. The most intensive uses are envisioned along Euclid Avenue and Holt Boulevard. The MU-1 zoning district is consistent with and implements the Downtown Mixed Use Area land use designation of the Policy Plan component of The Ontario Plan.

The surrounding land uses are also zoned MU-1 with commercial uses to the east and west and existing multi-family residences to the north of W. Emporia Street. The project site is adjacent to the Metrolink Riverside Line to the south.

The nearest noise sensitive residential land uses are located across W. Emporia Street to the north. The performance standards found in Section 5-29.04 (a) limit the exterior noise level at the existing multi-family residents to the north to the higher of the actual measured ambient noise level or 65 dBA Leq during the daytime hours, and 50 dBA Leq during the nighttime hours at the boundary of residential properties as described in Section 3.3 of this report. Additionally, since the measurement location is on the boundar y between two zones, the noise level limit of the lower category shall apply. Therefore, the threshold of 65 dBA Leq during the daytime and 50 dBA Leq during the nighttime shall apply.

Based on similar residential developments, a review of the proposed project indicates that noise sources from the roof-mounted mechanical ventila tion system (HVAC) is the primary source of stationary noise.

7.2 Reference Noise Levels

This section provides a detailed description of the reference noise level measurement results. It is important to note that the following projec ted noise levels assume the worst-case noise environment with all the mechanical ventilation uni ts all running at the same time. In reality, these noise levels will vary throughout the day. The mechanical ventilation units may operate during nighttime hours.

749

23 Ldn Consulting, Inc. 3/23/22 22-25 Ontario 9U Noise Air Conditioning Units

Rooftop mechanical ventilation units (HVAC) will be installed on the pr oposed buildings. The project anticipates installing Carrier CA15NA (S eries, 24-A) or equivalent HVAC units with a reference noise level of 71 dBA at 3-feet (Source: Carrier). The HVAC units will cycle on and off throughout the day. Typically, HVAC units run for approximately 20 minutes each operating cycle to provide the necessary heating or cooling. It is anticipated that the HVAC units will operate twice in any given hour or run for 40 minutes in any given hour. Noise levels drop 3 decibels each time the duration of the source is reduced in half. Therefore, hourly HVAC noise level over a 40 minute period would be reduced approximately 2 decibels to 69 dBA based on operational time.

To predict the property line noise level, a reference noise level of 69 dBA at 3-feet was used to represent the HVAC units.

The building could have as many as nine (9) temperature control units (HVAC) located along the south side of the building. No reductions from any parapet walls were incorporated into the modeling.

7.3 Findings

The HVAC noise levels along with the calculated hourly noise levels based upon individual operating times are shown below in Table 7-1 for the resident ial properties to the north. Also, included in Table 7-1 are the relative property line standards for clarity. No reductions from any parapet walls were incorporated into the modeling.

Based upon the property line noise levels determined above, the proposed developments related operational noise levels comply with the noise standards at the property lines. Additionally, Section 5-29.04 (a) of the City’s Municipal Code allows the property line standard to be the actual measured ambient level. It should be noted: as shown above in Table 4-1, average ambient noise levels are above the threshold. No Impacts are anticipated and no mitigation is required.

8.0 TRANSPORTATION NOISE LEVELS

8.1 Guidelines for the Determination of Significance

The Noise Element includes stan dards for land use compatibility for community noise exposure.

For the purposes of this project, the noise impacts associated with traffic are controlled by the Ontario Plan Noise Element. For noise sensitive residential areas, the exterior noise levels should remain below 65 dBA CNEL, and the interior noise levels should remain below 45 dBA CNEL.

8.2 Potential On-site Noise Impacts

To determine the future noise environment and im pact potential from the existing Union Pacific Railroad to the south, the results from the long-term noise measurements detailed in Section 4 were used to plot the future noise contours through the project site as shown in Figure 8-A. Based on the ambient noise measurements, the 65 dBA contour is located beyond the project limits without any shielding in the nort hern portion of the project site. Therefore, the noise sensitive uses including the front yard outdoor use areas could experience noise levels that exceed the City noise threshold of 65 dBA for multi-family residential uses.

The front yard outdoor use areas would be shielded from the existing rail line from the existing and proposed buildings. To determine the noise level reductions from the proposed building, the Fresnel Barrier Reduction Calculations based on distance, source height, receiver elevation and the top of barrier were modeled. The receptor wa s located 5 feet behind the proposed building.

It was determined that the proposed building would provided a minimum 14 dBA noise reduction.

Therefore, the proposed outdoor use areas are expected to be reduced to 58 dBA CNEL or lower, below the 65 dBA CNEL threshold with no additional mitigation. The Fresnel barrier reduction calculations for the building are provided in
Attachment A of this report.

8.3 Airport Related Noise

According to the Ontario International Airport Land Use Compatibility Plan, the Project is located within the 60 to 65 dBA CNEL noise impact zone, at approximately the 64 dBA CNEL contour or lower, within the Airport Influence Area (AIA), as shown on Exhibit 8-B. Based on the proposed multi-family residential land use for the proposed project, the ONT ALUCP identifies noise policies and criteria to minimize the interior noise expo sure generated by aircra ft activity. The noise criteria on Table 2-3 of the Ontario Internatio nal Airport Land Use Compatibility Plan indicates that multi-family residential uses located withi n the 60 to 65 dBA CNEL noise impact zone are considered normally compatible land use and must satisfy an interior noise level standard of 45 dBA CNEL.

8.4 Cumulative Onsite Noise Levels

The noise levels determined for the train and airp ort activities were combined to determine the overall cumulative noise levels at the proposed outdoor use areas. As determined above, the proposed outdoor use areas will be exposed to train noise levels of 58 dBA CNEL and aircraft noise levels of 64 dBA CNEL. The resultant cumulative noise levels from the train and airport activities were calculated to be 65 dBA CNEL and theref ore would comply with the City of Ontario Noise standards of 65 dBA CNEL at the multi-family residences and outdoor useable areas.

The City of Ontario as part of its noise guidelines also states, consistent with Title 24 of the California Code of Regulations (CCR), a project is required to perform an interior assessment on the portions of a project site where building façade noise levels are above 60 dBA CNEL in order to ensure a 45 dBA CNEL interior noise level. Based on the floor plans provided by JWDA-MS Architects, 2021, all sensitive living areas are located along the northern façade of the building away from the Union Pacific Railroad. Additionally, no glass assemb lies are proposed along the southern façade.

Therefore, to meet the interior noise limit of 45 dBA CNEL, all glass assemblies should have a minimum Sound Transmission Class (STC) rating of 28 or better. Exterior entry doors should be of solid core construction with a minimum STC rating of 28 or better.

8.5 Train Vibration

The project site is located approximately 55 feet north of the Union Pacific Railroad which services the Metrolink Riverside Line. The proposed building is located 120 feet from the centerline of the roadway. Rail-related noise comes from several potential sources. A locomotive engine’s propulsion system generates noise from mechanical and electrical systems. The interaction of wheels with the track produces various noises, particularly where the wheel encounters a flaw or defect along smooth wheel/track surfaces. Finally, train horn or bells and railroad crossing warning devices generate short but loud alerts pursuant to federal safety regulations.

The Los Angeles Economic Development Corporat ion prepared a "Los Angeles-Inland Empire Railroad Main Line Advanced Planning Study" in October of 2002. This study predicts that 33 freight trains will travel on the UPRR track in the ye ar 2025. Additionally, th e Southern California Association of Governments (SCAG) prepared the “Transportation System Passenger Rail” Technical Report stating that the Metrolink Riverside Line is currently only allowed 12 daily slots resulting in just six round trips per day along its corridor.

Train vibration depends on the weight of the train, travel speed, the condition of the track and soil characteristics. The proposed project build ings would be more than 120 feet from the centerline of the tracks. Federal Transit Administration Transit Noise and Vibration Impact Assessment Manual (FTA 2018) predicts that freight train vibration levels are as high as 74.4 754

28 Ldn Consulting, Inc. 3/23/22 22-25 Ontario 9U Noise VdB at 120 feet from the track centerline for a locomotive-powered freight train traveling at speeds of 50 MPH and up to 50.6 VdB for commuter rail train events at that speed.

Therefore, the occasional freight train activities will be below th e 75 VdB, occasional event for the freight train and the infrequent commuter train activities will be below the 80 VdB infrequent event annoyance thresholds as identified in Cate gory 2 of Table 3-1. Additionally, according to the SCAG report, average speeds along the Metrolink Riverside line is 41 mph. Due to the close proximity of the Transit Center, the commuter trains will be traveling at a slower speed of approximately 15 MPH, which would reduce the vibration levels 8 VdB and the freight train travel at speeds of 30 MPH or less which would reduce the vibration levels at least 4 VdB. Therefore, the train activities would have a less than significant impact on the proposed project.

The use of vibration dampening materials such as carpeting and upgraded windows and doors can significantly reduce the effects of groundborne vibration within the buildings. Measurements of impact isolation conducted by the FTA show that a vibration reduction for hard floor surfaces (such as tile or hardwood) is 2 VdB for each floor and at least 10 VdB for carpeted floors.

Additionally, the buildings are dependent on th e coupling of the building foundation to the soil and for wood framing would receive a 5 VdB reduction. The FTA guidelines also suggest a +6 VdB factor be included to account for amplification due to resonance of floors, walls and ceilings. 755

1. PROJECT DESCRIPTION

Project site consists of 0.46 acres of lot in size located at 413 W. Emporia St, Ontario.

The project site is currently vacant lot. The south of the property is near of a railroad, east is storage facility, the west side of the property is commercial building and the Emporia St is at the north of the project site. The site currently drains from north to south.

The project site has no offsite storm water contribution based on field topographic survey.

Proposed development of the site includes 9 units apartment. At post development, the drainage of the site will discharge to the Emporia Street via proposed drainage system.

STORMTECH MC-7200 will be used as underground infiltration basin for water quality purposes, and catch basin filter will be used for pretreatment, prior to draining into the infiltration system.

2. Purpose

The purpose of this study is to analyze the flows to and through the site and demonstrate that the flows leaving the site will not have an effect on downstream storm drain facilities.

3. Analysis

This report presents a hydrology analysis and effect on existing drainage systems for the proposed construction located at 413 Emporia St, Ontario. 100 yr has been taken as return period of rainfall intensity, and San Bernardino Hydrology manual was used for hydrology analysis. And also PWQMP report analyzes the volume of water to be stored on-site for water quality purposes. Post development flows will not exceed 80% of pre development one per city’s requirement.

1 row of 5 chamber and 2 end cap with 12” stone foundation will be used.

V = 1602.76 cf > 1481.04 cf (OK)

5. Percolation Rate Calculation

Per percolation report, infiltration rate, P=2.16 in/hr

A (Area of infiltration basin) = 443.05 sf

Drawdown Time (T) = (V/A)/(P/12)
= (1481.04/443.05)/(2.16/12) = 18.57 hr < 48.0 hr o.k.

6. ∆Q Analysis

Since City requires to limit the Q at post development as 80% of Q at pre development, find out the volume equivalent to ∆Q (=Q at post – 80% Q at pre) per hydrology analysis,

∆Q= Qpost- 0.8 x Qpre=2.65cfs – 0.8 x 2.66 cfs=0.52 cfs

100 year post-development peak flow will not exceed 80% of pre-development peak flow. Extra flows needs to be detained on site.

8. Conclusion

Based on analysis, Q at post development will be more than the discharge to 80% of Q at pre development. The extra flow will be detained on site by downstream storm-drain facilities and proposed underground infiltration basins have an enough capacity to carry the design Q from the project site.

1 Precipitation frequency (PF) estimates in this table are based on frequency analysis of partial duration series (PDS).

Numbers in parenthesis are PF estimates at lower and upper bounds of the 90% confidence interval. The probability that precipitation frequency estimates (for a given duration and average recurrence interval) will be greater than the upper bound (or less than the lower bound) is 5%. Estimates at upper bounds are not checked against probable maximum precipitation (PMP) estimates and may be higher than currently valid PMP values.

Please refer to NOAA Atlas 14 document for more information.

Surrounding sites were identified in the following databases.

Elevations have been determined from the USGS Digital Elevation Model and should be evaluated on a relative (not an absolute) basis. Relative elevation information between sites of close proximity should be field verified. Sites with an elevation equal to or higher than the target property have been differentiated below from sites with an elevation lower than the target property.

Page numbers and map identification numbers refer to the EDR Radius Map report where detailed data on individual sites can be reviewed.

Sites listed in bold italics are in multiple databases.

STANDARD ENVIRONMENTAL RECORDS
Lists of Federal CERCLA sites with NFRAP
SEMS-ARCHIVE: SEMS-ARCHIVE (Superfund Enterprise Management System Archive) tracks sites that have no further interest under the Federal Superfund Program based on available information. The list was formerly known as the CERCLIS-NFRAP, renamed to SEMS ARCHIVE by the EPA in 2015. EPA may perform a minimal level of assessment work at a site while it is archived if site conditions change and/or new information becomes available. Archived sites have been removed and archived from the inventory of SEMS sites. Archived status indicates that, to the best of EPA’s knowledge, assessment at a site has been completed and that EPA has determined no further steps will be taken to list the site on the National Priorities List (NPL), unless information indicates this decision was not appropriate or other considerations require a recommendation for listing at a later time. The decision does not necessarily mean that there is no hazard associated with a given site; it only means that. based upon available information, the location is not judged to be potential NPL site.

A review of the SEMS-ARCHIVE list, as provided by EDR, and dated 01/25/2023 has revealed that there is 1 SEMS-ARCHIVE site within approximately 0.5 miles of the target property.
