From: City Administrator
Subject:

RESOLUTION APPROVING AMENDMENT NO. 4 TO THE DESIGN-BUILD-OPERATE-

MAINTAIN AGREEMENT FOR FREEWAY-ORIENTED CITY ENTRY/DISPLAY SIGN AND ADOPTION OF A CLASS 32 CATEGORICAL EXEMPTION PURSUANT TO SECTION 15332 OF THE CALIFORNIA ENVIRONMENTAL QUALITY ACT
Financial Impact:

Fiscal Impact:

The proposed sign is expected to generate a minimum of $150,000 annually for each "Changeable Message Digital Display" panel installed, totaling $300,000 per year in General Fund revenue for the City ("Base Compensation"). Additional revenue may be provided to the City if the Base Compensation exceeds twenty-five percent (25%) of the advertising company’s total annual net revenue from the site.

Summary:

The Riverside/Orange County metropolitan area is a key hub for commerce, and the City of Placentia benefits greatly from its strategic position within this marketplace. The State Route 91 (SR-91) freeway, which runs through both counties, serves as a vital corridor for businesses looking to establish their brand and visibility. Placentia has a unique opportunity to leverage its location along a small segment of the SR-91 Freeway to enhance its exposure. By doing so, the City can maximize this visibility to diversify and strengthen its municipal revenue streams.

This action will approve a Resolution authorizing Amendment No. 4 to the Design-Build- Operate-Maintain (DBOM) Agreement for the installation of one (1) Freeway-Oriented City Entry/Display Sign featuring two digital displays at 1470 S. Placentia Avenue, while also adopting a Class 32 Categorical Exemption pursuant to Section 15332 of the State California Environmental Quality Act (CEQA) Guidelines.

Recommendation:

Recommended Action: It is recommended that the City Council:

1. Adopt Resolution No. R-2025-73, A Resolution of the City Council of the City of Placentia, California adopting a Class 32 Categorial Exemption pursuant to the California Environmental Quality Act (CEQA) set forth in Title 14 CCR § 15332 (Class 32 - In-Fill Development Projects) and the City of Placentia CEQA Guidelines and approving Amendment No. 4 to the Design, Build Operate and Maintain Agreement between the 1 City of Placentia and Lamar Central Outdoor, LLC for the construction and operation of one (1) Freeway-Oriented Entry Sign; and

2. Authorize the City Administrator, or her designee, to execute all necessary documents, in a form approved by the City Attorney.

Strategic Plan Statement:

This item is consistent with the City Council approved Five Year Strategic Plan Goal 1: Ensure Long-Term Fiscal Sustainability, specifically, Objective 1.4: Protect and preserve existing economic development/property nodes throughout the City to maximize revenue opportunities and Objective 1.5: Continue seeking ways to diversify the City’s revenue sources to prevent over-reliance on any one source (Measure U/Property Tax).

Discussion:

Many municipalities have recognized advertising revenue as a valuable funding source to support municipal operations and supplement traditional revenue streams. For Placentia, opportunities to increase existing revenues are limited, making the cultivation of new revenue sources especially important. Diversifying revenue helps enhance the City's fiscal stability, aligning with the recommendations made by the Citizens Fiscal Sustainability Task Force to the City Council in May 2015.

The City owns certain parcel of real property located on the northeast side of Placentia Avenue between the SR-91 freeway at 1470 S. Placentia Avenue, Placentia, CA 92870 (APN 344-037-01), as depicted on Exhibit A of Attachment 1. The City proposes to install one (1) freeway-oriented entry sign with two digital display capabilities on this parcel. This will allow the City to provide public service announcements and messages. This includes messages by those sponsored by non-profit organizations, City promotional announcements of City sponsored and co-sponsored events such as celebrations, festivals, special events, park and public facility openings as well as to promote economic development within the City, including placement of ads for key local businesses.

Planning Commission Review
On November 10, 2025, the Planning Commission evaluated the addition of a freeway- oriented entry sign with digital/static display capabilities, located on City-owned property directly northeast of Placentia Avenue and SR-91 freeway. The Planning Commission adopted a Resolution making certain findings with respect to the consistency of the proposed installation of the sign with the City of Placentia General Plan pursuant to California Government Code § 65402.

Compliance with California Environmental Quality Act (CEQA) The proposed billboard at 1470 S. Placentia Avenue, meets all criteria for a Class 32 Categorical Exemption pursuant to Section 15332, of the State CEQA Guidelines and no exceptions are applicable.

Fiscal Impact Summary:

The proposed sign is expected to generate a minimum of $150,000 annually for each 2 "Changeable Message Digital Display" panel installed, totaling $300,000 per year in General Fund revenue for the City ("Base Compensation"). Additional revenue may be provided to the City if the Base Compensation is more than twenty-five percent (25%) of the advertising company’s total annual net revenue.

CATEGORICAL EXEMPTION REPORT
This report serves as the technical documentation of an environmental analysis performed by PGN, for the proposed 1470 S. Placentia Avenue Billboard project in the City of Placentia. The intent of the analysis is to document whether the project is eligible for a Class 32 Categorical Exemption (CE). The report provides an introduction, environmental checklist, and evaluation of the project’s consistency with the requirements for a Class 32 exemption.

1. INTRODUCTION
The California Environmental Quality Act (CEQA) states that a Class 32 CE is allowed when:
(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.
(b) The proposed development occurs within city limits on a project site of no more than five acres substantially surrounded by urban uses. (c) The 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.
(e) The site can be adequately served by all required utilities and public services.

Additionally, State CEQA Guidelines Section 15300.2 requires a review for exceptions including hazardous waste sites, historic resources, scenic highways, cumulative effect and significant effects as a result of the project. PGN evaluated the project’s consistency with the above requirements, including its potential impacts in the areas of air quality, biological resources, hazardous waste sites, historic resources, noise, traffic, and water quality to confirm the project’s eligibility for the Class 32 exemption.

Other Public Agencies whose approval is required: Approval by the Placentia City Council is required for the proposed Agreement and adoption of a Notice of Exemption.

The City of Placentia will also be responsible for the issuance of a building permit by the City’s Development Services Department prior to installation of the proposed structure.

The California Department of Transportation (Caltrans) is a responsible agency and a general outdoor advertising display visible from the State Highway System requires an Outdoor Advertising Permit prior to construction.

Have California Native American tribes traditionally and culturally affiliated with the project area requested consultation pursuant to Public Resources Code Section 21080.3.1? If so, is there a plan for consultation that includes, for example, the determination of significance of impacts to tribal cultural resources, procedures regarding confidentiality, etc.? No. Projects exempt from CEQA are not required to enter into a tribal cultural resource consultation. 3 | Page

24 Proposed 1470 S. Placentia Billboard Project CEQA Class 32 Categorical Exemption Report Evaluation of Environmental Impacts
The following instructions are for the evaluation of project impacts in the Environmental Checklist:

1. A brief explanation is required for all answers except "No Impact" answers that are adequately supported by the information sources the City cites in the parentheses following each question. A "No Impact" answer is adequately supported if the referenced information sources show that the impact simply does not apply to projects like the one involved (e.g., the project falls outside a fault rupture zone). A "No Impact" answer should be explained where it is based on project-specific factors as well as general standards (e.g., the project will not expose sensitive receptors to pollutants, based on a project-specific screening analysis).

2. All answers must take account of the whole action involved, including off-site as well as on-site, cumulative as well as project-level, indirect as well as direct, and construction as well as operational impacts.

3. For the purpose of this checklist, “prior EIR” means the environmental impacts report certified for a planning level decision, as supplemented by any subsequent or supplemental environmental impact reports, negative declarations, or addenda to those documents. “Planning level decision” means the enactment or amendment of a general plan, community plan, specific plan, or zoning code. (State CEQA Guidelines Section 15183.3(e).)

4. Once the City staff has determined that a particular physical impact may occur as a result of a project, then the checklist answers must indicate whether the impact has already been analyzed in a prior EIR. If the effect of the project is not more significant than what has already been analyzed, that effect of the project is not subject to CEQA.

The brief explanation accompanying this determination should include page and section references to the portions of the prior EIR containing the analysis of that effect. The brief explanation shall also indicate whether the prior EIR included any mitigation measures to substantially lessen that effect and whether those measures have been incorporated into the project.

5. If the project would cause a significant adverse effect that either is specific to the project or project site and was not analyzed in a prior EIR, or is more significant than was analyzed in a prior EIR, the City must determine whether uniformly applicable development policies or standards that have been adopted by the City would substantially mitigate that effect. If so, the checklist shall explain how the project’s implementation of the uniformly applicable development policies will substantially mitigate the effect. That effect of the project is not subject to CEQA if the City makes a finding, based upon substantial evidence, that the development policies or standards will substantially mitigate that effect.

6. If all effects of a project were either analyzed in a prior EIR or are substantially mitigated by uniformly applicable development policies or standards, CEQA does not apply to the project, and the City shall file a Notice of Exemption.

7. Effects of a project that either have not been analyzed in a prior EIR, or that uniformly applicable development policies or standards do not substantially mitigate, are subject to CEQA. With respect to those effects of the project that are subject to CEQA, the checklist shall indicate whether those effects are significant, less than significant with 10 | Page
25 Proposed 1470 S. Placentia Billboard Project CEQA Class 32 Categorical Exemption Report mitigation, or less than significant. If there are one or more “Significant Impact” entries when the determination is made, a EIR is required. The EIR should be limited to analysis of those effects determined to be significant. (State CEQA Guidelines Sections 15128, 15183.3(d).)

8. Mitigation measures required by the General Plan EIR or other relevant CEQA document relied on for environmental review of this Project will be implemented as discussed below.

9. The explanation of each issue should identify:
a. the significance criteria or threshold, if any, used to evaluate each question; and b. the mitigation measure identified, if any, to reduce the impact to less than

significance.

Source: City of Placentia General Plan and GP EIR, 2019 and Daktronics Lighting Analysis dated October 2, 2025.
a) Analyzed in the Prior GP EIR. The Placentia General Plan does not identify any scenic vistas within the City boundaries. Additionally, the General Plan EIR states that the City is approaching full buildout with 98 percent of the city developed and that the City does not offer any scenic resources. The proposed sign location is within a highly urbanized area along to S. Placentia Avenue and adjacent to SR-91 freeway corridor and no scenic vistas exist at these locations; therefore, the construction of the proposed sign would have a less than significant effect on a scenic vista. No mitigation measures are required.
b) Analyzed in the Prior GP EIR. The project site is located in an urban setting characterized by a mix of single-family residential, commercial and industrial development. Views of the existing streetscape are characterized by low height (one-story to two-story) buildings, utilities (including utility lines, poles, and street lights) and landscaping. There are no designated scenic highways or scenic resources in the vicinity of the proposed sign. Impacts would be less than significant and no mitigation measures are required.
c) Analyzed in the Prior GP EIR. The Placentia General Plan does not identify any scenic vistas within the City boundaries. The construction of the proposed sign would not conflict with General Plan policies relating to scenic resources. The project will be consistent with applicable zoning regulations for the Manufacturing District. No mitigation measures are required.
d) Substantially Mitigated by Uniformly Applicable Development Policies. The area adjacent to the proposed sign is fully urbanized with a significant amount of existing light and glare. The proposed sign would incrementally add to the existing level of light 12 | Page
27 Proposed 1470 S. Placentia Billboard Project CEQA Class 32 Categorical Exemption Report and glare in the area. The lighting intensity of billboards adjacent to highways is regulated by California Vehicle Code § 21466.5, which requires the intensity level of billboard copy to be adjusted based on ambient light levels, as follows:
“No person shall place or maintain or display, upon or in view of any highway, any light of any color of such brilliance as to impair the vision of drivers upon the highway. A light source shall be considered vision impairing when its brilliance exceeds the values listed below. The brightness reading of an objectionable light source shall be measured with a 1-1/2-degree photoelectric brightness meter placed at the driver's point of view. The maximum measured brightness of the light source within 10 degrees from the driver's normal line of sight shall not be more than 1,000 times the minimum measured brightness in the driver's field of view, except that when the minimum measured brightness in the field of view is 10 foot-lamberts or less, the measured brightness of the light source in foot-lambert shall not exceed 500 plus 100 times the angle, in degrees, between the driver's line of sight and the light source.” A lighting analysis (see Appendix A) has been prepared analyzing light intensity levels of the proposed billboard faces at various angles and distances from the proposed sign. The nearest residences to the proposed sign are located approximately 47 feet downslope to the east. The highest estimated lighting intensity at these residences would be approximately 0.3 foot-candles assuming an all -white display and absolute darkness in the vicinity of the sign. A foot-candle is the light intensity emitted by one candle at a distance of one foot. The presence of nighttime ambient light, such as roadway lighting, residential lighting, commercial lighting, the moon, etc. would diminish the impact of the light output from the sign. In the context of the highly urbanized setting, this level of lighting intensity is not considered to be a significant source of light or glare that would adversely affect day or nighttime views. In addition, the following mitigation measures would require the lighting intensity level of the proposed sign to comply with state regulations and also require periodic monitoring, which would reduce this potential impact to a level that is less than significant.

AES-1 Lighting intensity levels for the sign shall not exceed the current standards set forth in the California Vehicle Code, California Outdoor Advertising Act, or Federal Highway Administration guidelines or regulations, whichever is most restrictive, as they may be amended from time to time. Prior to issuance of building permits for the sign, evidence shall be submitted in a manner acceptable to the City Engineer demonstrating that the design and operational characteristics of the sign comply with all state and federal standards, and all required Caltrans permits have been obtained.

AES-2 To ensure that the lighting intensity level is consistent with those described in the lighting analysis (Appendix A), quarterly field monitoring shall be conducted by a qualified technician approved by the City using the method described in the OAAA publication titled “Digital Billboard Foot-Candle Measurement”. If field monitoring indicates that the lighting intensity level exceeds those described in the lighting analysis, the City Engineer shall immediately cause the sign’s operation be modified to conform to the lighting analysis.

29 Proposed 1470 S. Placentia Billboard Project CEQA Class 32 Categorical Exemption Report August 18, 2015 and California Emission Estimator Model (CalEEMod), Version 2022.1.1.30, 2025.
a) Less Than Significant. The South Coast 2022 AQMP incorporates land use assumptions from local general plans and regional growth projections developed by the SCAG to estimate stationary and mobile air emissions associated with projected population and planned land uses. If the proposed land use is consistent with the local general plan, then the impact of the project is presumed to have been accounted for in the AQMP. This is because the land use and transportation control sections of the AQMP are based on the SCAG regional growth forecasts, which incorporate projections from local general plans. The project is consistent with the General Plan land use designation of Industrial. Therefore, the land use would continue to be consistent with the local general plan and the impacts of the project are still accounted for in the AQMP. Another measurement tool in evaluating consistency with the AQMP is to determine whether a project would generate population and employment growth and, if so, whether that growth would exceed the growth rates forecasted in the AQMP and how the project would accommodate the expected increase in population or employment. The project would create minimal increase in population and overall vehicle miles traveled (VMT) during construction and operations, which would be included in the growth rates forecasted in the AQMP.
b) Less Than Significant with Mitigation Measures. Since the SCAB is currently in nonattainment for ozone and PM 2.5 , related projects may exceed an air quality standard or contribute to an existing or projected air quality exceedance. The SCAQMD neither recommends quantified analyses of construction and/or operational emissions from multiple development projects nor provides methodologies or thresholds of significance to be used to assess the cumulative emissions generated by multiple cumulative projects.

Instead, the District recommends that a project’s potential contribution to cumulative impacts be assessed by utilizing the same significance criteria as those for project- specific impacts. Furthermore, the SCAQMD states that if an individual development project generates less-than-significant construction or operational emissions impacts, then the development project would not contribute to a cumulatively considerable increase in emissions for those pollutants for which the Basin is in nonattainment.

Potential impacts to air quality could occur during sign construction and during on-going operations. The following discussion is based on the air quality impact analysis conducted by Giroux and Associates as part of the CEQA analysis for a similar sign project at 380 S.

Placentia Avenue. The Giroux air quality study was part of the IS/MND certified by the City on October 6, 2015. The City finds that because the type of equipment to be used, the duration of construction activities, and ongoing operational characteristics for the proposed 1470 S. Placentia Avenue sign would be substantially similar to those for the 380 S. Placentia Avenue sign, the findings from the 2015 air quality analysis accurately reflect potential impacts that would result from the proposed 1470 S. Placentia sign.

Construction Emissions
During construction, emissions would be generated by gasoline-or diesel-powered construction equipment. Fugitive dust emissions could also occur during site preparation and excavation. Based upon the anticipated duration of construction being 4 days and the type of equipment used (1 drill/bore rig, 1 loader/backhoe, and 1 crane), the following table summarizes the projected levels of emissions that would be expected to occur compared to the thresholds of significance established by the SCAQMD. As seen in the table, the total projected emissions for the sign would be substantially less than 15 | Page
30 Proposed 1470 S. Placentia Billboard Project CEQA Class 32 Categorical Exemption Report SCAQMD thresholds for all categories of pollutants based on modeling using the California Emissions Estimator Model (CalEEMod) Version 2022.1.1.30.

Construction Emissions 0.69 6.44 11.2 0.02 0.32 0.25
SCAQMD Thresholds 75 100 550 150 150 55
Although emissions would be less than significant without mitigation, the following measures are required by AQMD regulations and will be required by the City in order to minimize potential impacts.

Mitigation Measures
AQ-1 During construction, the following requirements shall be enforced by the City Building Official in order to reduce fugitive dust emissions:

1. Prepare a high wind dust control plan.

2. Cover all stock piles with tarps at the end of each day or as needed.

3. Provide water spray during loading and unloading of earthen materials.

4. Minimize in-out traffic from construction zone.

5. Sweep streets daily if visible soil material is carried out from the construction site.

AQ-2 During construction, the following requirements shall be enforced by the City Building Official to reduce equipment exhaust emissions:

1. Utilize well-tuned off-road construction equipment.

2. Establish a preference for contractors using Tier 3 or better heavy equipment.

3. Enforce 5-minute idling limits for both on-road trucks and off-road equipment.

Prior to issuance of any building permits the Building Official shall ensure that these requirements are noted on the construction drawings, and the Building Inspector shall confirm that they are adhered to throughout the construction phase.

Operational Emissions
The proposed sign would be hard-wired to the electrical grid and no on-site generators would be used during operation, therefore the sign would not directly generate emissions on site. Off-site emissions could increase incrementally due to an increased demand for electricity from electrical generation facilities. However, electrical consumption has no single uniquely related air pollution emissions source because power is supplied to and drawn from a regional grid. Electrical power is generated regionally by a combination of non-combustion (nuclear, hydroelectric, solar, wind, geothermal, etc.) and fossil fuel combustion sources. There is no direct nexus between consumption and the type of power source or the air basin where the source is located. Operational air pollution emissions from electrical generation are not 16 | Page
31 Proposed 1470 S. Placentia Billboard Project CEQA Class 32 Categorical Exemption Report attributable on a project-specific basis and therefore are considered less than significant.

In addition, emissions from fossil fuel generation facilities are expected to decline over time as older plants are upgraded with new pollution control technology or are replaced with cleaner power plants.

During operation, the routine monthly maintenance is assumed to involve light-duty truck traffic to the site, or approximately 12 trips per year. As seen in the following table, total projected emissions for ongoing maintenance operations would be substantially less than SCAQMD thresholds for all categories of pollutants.

Operations Emissions 0.00 0.00 0.00 0.00 0.00 0.00
SCAQMD Thresholds 55 55 550 150 150 55
Maintenance vehicles must comply with state and federal emissions regulations, and potential impacts related to ongoing operation would be less than significant. No mitigation measures are required.
c) - d) Less Than Significant. During construction, dust and other air pollutants and odors could be generated by gasoline-or diesel-powered equipment. Required compliance with AQMD regulations (e.g., watering to suppress dust, regular maintenance and tune-ups of construction equipment and vehicle engines, location of staging areas as far as practical from sensitive land uses) and Mitigation Measure AQ-1 would reduce these potential impacts to a level that is less than significant. 2-4 BIOLOGICAL RESOURCES

b) Less Than Significant with Mitigation. Construction of the sign foundation would involve subsurface excavation, which has the potential to disturb archaeological resources that could be present. However, the project site is not located within a known area of archaeological sensitivity. In the event that archaeological artifacts were uncovered during construction, Mitigation Measure CUL-1 would reduce this potential impact to a level that is less than significant.

The Building Official shall ensure that a note describing this requirement is placed on all grading and building plans.
c) Less Than Significant with Mitigation. The project site has been disturbed during prior construction of the S.

However, should any human remains be uncovered during construction, Mitigation Measure CUL-2 would reduce impacts in this regard to a level that is less than significant.

CUL-2 Should any human bone be encountered during excavation, all activity shall cease immediately and the contractor shall notify the City Building Official. The Building Official shall notify the County Coroner pursuant to §§5097.98 and 5097.99 of the Public Resources Code relative to Native American remains. Should the Coroner determine the human remains to be Native American, the Native American Heritage Commission shall be contacted pursuant to Public Resources Code §5097.98, and a mitigation plan shall be developed and implemented pursuant to state law.

Source: City of Placentia General Plan and GP EIR, 2019 a) Less Than Significant. According to the CEQA Guidelines § 15126.2(d), “uses of nonrenewable resources during the initial and continued phases of the project may be irreversible since a large commitment of such resources makes removal or nonuse thereafter unlikely. Primary impacts and, particularly, secondary impacts (such as highway improvement that provides access to a previously inaccessible area) generally commit future generations to similar uses. Also, irreversible damage can result from environmental accidents associated with the project. Irretrievable commitments of resources should be evaluated to assure that such current consumption is justified.” Therefore, the purpose of this analysis is to identify any significant irreversible environmental effects of project implementation that cannot be avoided. 19 | Page
34 Proposed 1470 S. Placentia Billboard Project CEQA Class 32 Categorical Exemption Report Both construction and operation of the project would lead to the consumption of limited, slowly renewable, and non-renewable resources, committing such resources to uses that future generations would be unable to reverse. The new development would require the commitment of resources that include (1) building materials, (2) fuel and operational materials/resources and (3) the transportation of goods and people to and from the project.

During project construction, energy would be consumed in the form of electricity associated with the conveyance of water used for dust control and, on a limited basis, powering lights, electronic equipment, or other construction activities necessitating electrical power. Construction activities for the erection of an outdoor advertising display typically do not involve the consumption of natural gas. Project construction would also consume energy in the form of petroleum-based fuels associated with the use of off-road construction vehicles and equipment on the project site, construction worker travel to and from the project site, and delivery and haul truck trips hauling solid waste from and delivering building materials to the project site. During project operation, energy would be consumed for powering the outdoor advertising display and maintenance vehicle trips.

Estimated project operation total and per-capita energy usage, which was estimated by CalEEMod as part of the greenhouse gas emissions analysis, is shown in Section 2-8.

Vehicle miles traveled (VMT) were used as a surrogate for energy from consumption of transportation fuels. While a variety of factors govern the relationship between VMT and fuel energy, in general, an increase in VMT results from an increase in motor vehicle energy use. The project would comply with all applicable regulations and codes which require achievement of various levels of energy efficiency in construction and operation.

The commitment of resources required for the construction and operation of the project would limit the availability of such resources for future generations or for other uses during the life of the project. However, the use of such resources would be reduced when compared to what they would be in the absence of complying with Building Codes.

Therefore, energy consumption would not result in a substantial increase in energy production for energy providers and the energy demand associated with the project would be less than significant.
b) No Impact. The City of Placentia does not have local energy plans. Therefore, there would be no conflict, and there would be less than significant impacts. 20 | Page

Source: City of Placentia General Plan and GP EIR, 2019 a) Analyzed in the Prior GP EIR. The Alquist-Priolo Earthquake Fault Zoning Act was passed in 1972 to mitigate the hazard of surface faulting to structures for human occupancy. The Act’s main purpose is to prevent the construction of buildings used for 21 | Page
36 Proposed 1470 S. Placentia Billboard Project CEQA Class 32 Categorical Exemption Report human occupancy on the surface trace of active faults. The law requires the State Geologist to establish regulatory zones (known as Earthquake Fault Zones) around the surface traces of active faults and to issue appropriate maps. According to California Department of Conservation maps, the City of Placentia is not affected by any State- established Earthquake Fault Zone. According to the Placentia General Plan, the Whittier Fault forms the northerly extension of the Elsinore Fault (a major active zone). The Whittier Fault is considered potentially active requiring appropriate construction setbacks from its surface trace. Whittier Fault is at least 1,000 feet north of the City limits; therefore, it is not expected to have any direct impact on the proposed sign. Potential impacts related to Alquist-Priolo zones would be less than significant and no mitigation measures are required.
b) Analyzed in the Prior GP EIR. Placentia is located within a seismically active region of Southern California. The region’s major active faults include the San Andreas, Norwalk, Whittier/Elsinore, Newport/Inglewood, and Sierra Madre/San Fernando faults, among others, which are potential sources of seismic ground shaking within the city. Due to Placentia’s location with respect to the known active and potentially active faults present in Southern California, the potential for ground shaking in the city is considered generally moderate. The intensity of ground shaking would depend upon the magnitude of the earthquake, distance to the epicenter, and the geology of the area between the epicenter and the site. The General Plan concluded that although ground rupture is not considered to be a major concern for the City of Placentia, it is still likely that the city will be subject to some moderate to severe seismic shaking. The intensity of ground-shaking would depend upon the magnitude of the earthquake, distance to the epicenter and the geology of the area between the epicenter and the City. Some degree of structural damage is likely to occur due to strong seismic shaking; however, the risk of substantial damage can be reduced through adherence to seismic design codes (California Building Code 2022 or subsequently adopted version). According to the California Division of Mines and Geology’s Seismic Hazard Zones Maps (Anaheim and Orange Quadrangles) and in in Figure 4.8-2, Potential Liquefaction and Landslide Hazard Zones of the General Plan EIR, the site is not located in any seismic hazard zone, including liquefaction. The proposed sign would not be occupied, and therefore the only risk due to seismic activity would occur if the structure were to fall onto an occupied building, a person outside a building, or onto a roadway creating a traffic hazard.

The City regulates all development under the requirements of the current 2022 California Building Code (see PMC Title 20) and will follow the 2025 Code upon its effective date of January 1, 2026. The effects of ground shaking, landslides and soil conditions would be substantially mitigated through design and construction in conformance with the Building Code and applicable engineering standards. Therefore, the proposed sign would not expose people or structures to significant adverse impacts involving strong seismic ground shaking. No mitigation measures are required.
c) Less Than Significant. Clearing, grading and excavation during construction of the proposed sign could expose soils to short-term erosion by wind and water, and loss of topsoil. Grading and building plans are required to include drainage and erosion control measures to minimize the impacts from erosion and sedimentation during excavation.

Required compliance with the National Pollutant Discharge Elimination System (NPDES) and PMC Chapter 16.20, Stormwater Runoff and Urban Pollutant Control, as well as NPDES requirements for erosion control, grading, and soil remediation, would reduce potential impacts to a level that is less than significant. No mitigation measures are necessary.

e) No Impact. Expansive soils have the potential to expand when water is added and shrink when water is lost and can result in damage to overlying structures and infrastructure. The site is not located on a geologic unit or soil that is unstable or expansive. No mitigation measures are required.
f) No Impact. No septic tanks or wastewater systems are proposed in connection with the project. No impacts would occur and no mitigation measures are necessary. g) Less Than Significant with Mitigation Measures. Construction of the sign foundation would involve subsurface excavation, which has the potential to disturb paleontological resources that could be present. However, the project site is not located within a known area of paleontologic sensitivity (Orange County General Plan, Figure VI 9). In the event that paleontological artifacts were uncovered during construction, Mitigation Measure GEO-1 would reduce this potential impact to a level that is less than significant.

GEO-1 If evidence of subsurface paleontological resources or artifacts is uncovered during excavation, work shall be halted immediately and the City Building Official shall be notified. The Building Official shall require that a paleontological resources investigation is conducted by a qualified investigator and if the find is determined to be significant, a mitigation plan shall be implemented to meet the requirements of CEQA Guidelines §15064.5. The Building Official shall ensure that a note describing this requirement is placed on all grading and building plans.

Potential impacts related to greenhouse gas emissions could occur during sign construction and during on-going operation. The following discussion is based on the air quality impact analysis conducted by Giroux and Associates as part of the CEQA analysis 23 | Page
38 Proposed 1470 S. Placentia Billboard Project CEQA Class 32 Categorical Exemption Report for a similar sign project at 380 S. Placentia Avenue. The Giroux air quality study was part of the IS/MND certified by the City on October 6, 2015. The City finds that because the type of equipment to be used, the duration of construction activities, and ongoing operational characteristics for the proposed 1470 S. Placentia Avenue sign would be substantially similar to those for the 380 S. Placentia Avenue sign, the findings from the 2015 air quality analysis accurately reflect potential impacts that would result from the proposed 1470 S. Placentia sign.
a) Less Than Significant. The CEQA Guidelines require a lead agency to make a good- faith effort based, to the extent possible, on scientific and factual data in order to describe, calculate, or estimate the amount of greenhouse gas (GHG) emissions resulting from a project. In 2008, the SCAQMD adopted an Interim Quantitative GHG Significance Threshold for industrial projects where the SCAQMD is the lead agency (e.g., stationary source permit projects, rules, plans, etc.) of 10,000 Metric Tons (MT) CO2 equivalent/year. In 2010, the SCAQMD Working Group released revisions which recommended a threshold of 3,000 MT CO2e for all land use type projects. This more conservative 3,000 MT/year recommendation has been used as a guideline for this analysis. In the absence of an adopted numerical threshold of significance, project related GHG emissions in excess of the guideline level are presumed to trigger a requirement for enhanced GHG reduction at the project level.

Construction Emissions
During construction, emissions would be generated by gasoline-or diesel-powered construction equipment. The anticipated duration of construction for the proposed sign is expected to be approximately 3 days. Estimated total GHG emissions would be 2.12 MT CO2e, or less than 0.1 percent of the SCAQMD threshold. Although emissions would be far below the level of significance, required compliance with Mitigation Measure AQ-1 during construction would further reduce GHG emissions.

Operational Emissions
The proposed sign would be hard-wired to the electrical grid and no on-site generators would be used. As discussed in the Air Quality analysis, monthly maintenance trips are assumed. Vehicular emissions from 12 maintenance trips per year are estimated to be

0.0 MT CO2e per year.

Indirect emissions would also result from electrical generation for sign lighting.

Electricity is generated from a variety of resources at various locations in the western United States. The California Climate Action Registry Protocol (2009) states that each megawatt-hour (MW-HR) of electricity consumption in California results in the release of

0.331 MT of CO2e. The proposed sign is expected to consume 100 MW-HR/year, which would result in total emissions of 33.1 MT CO2e.

Total operational emissions from both maintenance and electrical generation is estimated to be approximately 33.1 MT CO2e, which is substantially less than the SCAQMD recommended significance threshold of 3,000 MT/yr. Impacts would be less than significant and no mitigation measures are required.
b) No Impact. There are no City policies or regulations for greenhouse gas emissions, therefore the applicable GHG planning guidance is Assembly Bill 32. As discussed in a) above, impacts from construction and operation of the proposed sign would be less than significant and would not conflict with any applicable plan, policy or regulation related to 24 | Page

Source: City of Placentia General Plan and GP EIR, 2019 a) Less Than Significant. During construction, flammable fuels and materials would be used on-site. Existing City building and fire regulations requiring proper safety precautions would reduce this potential impact to a level that is less than significant. No hazardous materials would be expected to be used or stored on-site after completion of construction. Therefore, impacts regarding transport, use or disposal of hazardous materials would be less than significant. No mitigation measures are required. b) Less Than Significant. As noted in a) above, flammable or hazardous materials could be used during construction; however, standard safety protocols required under City regulations would reduce this potential impact to a level that is less than significant.

No mitigation measures are required.
25 | Page
40 Proposed 1470 S. Placentia Billboard Project CEQA Class 32 Categorical Exemption Report c) Less Than Significant. There are no schools located within one-quarter mile of the project site. Since the proposed sign would not emit hazardous emissions or handle acutely hazardous materials, the requirements noted in a) and b), above, would reduce impacts to a level that is less than significant. No mitigation measures are required. d) No Impact. There are no sites in Placentia on a hazardous materials sites list. No impacts would occur and no mitigation measures are necessary. e) No Impact. There are no airports located within the city or in its immediate vicinity.

The nearest airport (Fullerton Municipal Airport) is located approximately 6.7 miles northwest of the project site. The project site is outside the Height Restriction Zone area for Fullerton Airport. Therefore, the proposed project would not result in a safety hazard related to aircraft operations. No impacts would occur and no mitigation measures are required.

a) Less Than Significant. Grading and excavation for the proposed sign could expose loose soil to wind and water erosion. If not controlled, the transport of these materials to local waterways could temporarily increase suspended sediment concentrations and release pollutants attached to sediment particles into local waterways. Required compliance with standard grading and building permit erosion control and water quality requirements (e.g., berms, sediment basins and traps, silt fences, straw dikes) would reduce these potential impacts to a level that is less than significant. No mitigation measures are necessary.
b) No Impact. The proposed sign would not use water, other than for dust suppression during construction, nor substantially interfere with groundwater recharge. There will be no impacts and no mitigation measures are necessary.

b) Less Than Significant Impact. The City of Placentia and the California Department of Transportation (Caltrans) have jurisdiction over the proposed project. Section 2-1, d) above (Aesthetics/Light and Glare) also addresses the issues subject to Caltrans jurisdiction. There are no potential conflicts with applicable plans, policies and regulations of the City of Placentia. The project site is not within a habitat conservation plan or NCCP area. The lighting intensity would be limited in conformance with state regulations regarding signage along freeways.

State Standards:

The Outdoor Advertising Act (Business and Professions Code Sec. 5200 et seq.) establishes locational standards for advertising displays along highways. Signs in business areas within 660 feet of a highway under Caltrans jurisdiction must be separated by at least 500 feet (static displays) or 1,000 feet (digital displays) on the same side of the highway. Since the proposed sign would be within 660 feet of the right of-way of a highway facility under Caltrans jurisdiction, it is subject to Caltrans 28 | Page
43 Proposed 1470 S. Placentia Billboard Project CEQA Class 32 Categorical Exemption Report permitting requirements. The proposed sign would not conflict with those requirements because it would be located on property that is zoned industrial and would not violate applicable spacing requirements.

construction of the proposed sign.

Short-Term Construction Impacts
City noise standards are established in Chapter 23.76 of the Placentia Municipal

Code; however, Section 23.76.070.8 of the Code exempts construction noise from

those standards during the hours of 7 a.m. to 7 p.m. Monday through Friday and

9:00 a.m. to 6:00 p.m. on Saturday. Noise levels during construction can be

estimated based upon the type of construction equipment and duration of

construction. No blasting or pile driving would be permitted in connection with sign

construction. The following table summarizes typical noise levels for the types of

construction equipment expected to be used during sign construction:

Table 4

NOISE SOURCES

Principal Noise Sources Reference Noise Level, (Lmax in dBA at 50 feet) Drill Rig 79
Crane 81
Loader/Backhoe 78
Flat Bed Truck 74
Source: FHWA, 2011
The nearest noise-sensitive use to the project site is the residential neighborhood to the east (downslope from the project) and the closest homes are approximately 47 feet from the proposed sign location. These noise levels are based on a direct line-of-sight path between the noise source and the receptor. These estimated noise levels would be less than significant when considering that grading/construction activity would be expected to last only 3 to 5 days and City noise regulations limit construction to daytime hours. No mitigation measures are required.
c) Less Than Significant. Construction activities generate ground-borne vibration when heavy equipment travels over unpaved surfaces or when it is engaged in soil movement. Excessive groundborne vibration is typically caused by activities such as blasting in mining operations or pile driving. No blasting or pile driving would occur during construction of the proposed sign. The effects of ground-borne vibration include discernable movement of building floors, rattling of windows, shaking of items on shelves or hanging on walls, and rumbling sounds. Vibration-related problems generally occur due to resonances in the structural components of a building because structures amplify groundborne vibration. Within the “soft” sedimentary surfaces of much of Southern California, ground vibration is quickly damped out. Groundborne vibration is almost never annoying to people who are outdoors. Groundborne vibration from construction activities rarely reaches levels that can damage structures. Because vibration is typically not an issue, very few jurisdictions have adopted vibration significance thresholds. Vibration thresholds have been adopted for major public works construction projects, but these relate mostly to structural protection (cracking foundations or stucco) rather than to human annoyance. The nearest residence is approximately 50 feet from the construction site. When considering that construction is expected to last only 3 to 5 days and is 30 | Page

The proposed sign would have no effect on the use or safety of public transit, bicycles or pedestrian facilities. The project would not conflict with transportation related plans, programs ordinances or policies.

Therefore, there will be no impacts on the performance of the circulation system. No mitigation measures are necessary.
b) No Impact. The City’s Traffic Impact Study Guidelines include screening criteria for project types that can be presumed to result in a less-than-significant transportation impact. This is also consistent with the recommendations in OPR’s Technical Advisory.

Based on the City’s Guidelines and recommendations in the OPR Technical Advisory, the project can be screened out from a full VMT assessment as it is presumed to result in a less-than-significant transportation impact due to the number of projected vehicle trips.

The project is anticipated to have 12 operational trips annually. No mitigation measures are necessary.
c) Less Than Significant. Billboard signs visible from roadways have the potential to distract drivers and result in safety hazards; however, existing state and federal regulations and guidelines for digital billboards would reduce these potential impacts to a level that is less than significant.

The Federal Highway Administration (FHWA) has issued recommendations regarding outdoor advertising signs adjacent to highways (FHWA, 2007) and the California Department of Transportation (Caltrans) implements the permit requirements of the state Outdoor Advertising Act (Business and Professions Code, §2240 et seq.) affecting the operation of digital billboards. A permit from Caltrans is required to place an outdoor advertising sign adjacent to a state highway. State standards relating to highway safety include the following:
• Must be outside the right of way of any highway.
• Display must be 500 feet from any other permitted display on same side of any highway that is a freeway.
• An electronic changeable message center display must meet the above spacing requirements and be 1,000 feet from another electronic message center display. • Maximum height for the advertising display area is 25 feet in height and 60 feet in length, not to exceed an overall maximum of 1,200 square feet. • The lighting intensity of digital displays is regulated by California Vehicle Code Sec. 21466.5.

In addition to these state standards, the FHWA has issued recommendations regarding digital billboards, including the following:
• Duration of message display of between 4 and 10 seconds, with 8 seconds recommended.
• Transition between messages between 1 and 4 seconds, with 1-2 seconds recommended.
• Brightness should be adjusted in response to changes in light levels so that the signs are not unreasonably bright for the safety of the motoring public. 33 | Page

3. CONSISTENCY ANALYSIS
Criterion (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.

Permitted Uses. According to the City of Placentia General Plan Land Use Map, the project site is designated as Industrial. The Industrial land use designation provides for industrial uses with a maximum FAR of 1.0. Industrial uses are high traffic generators and adequate access to these uses and buffering from surrounding sensitive uses should be provided. Zoning classifications compatible with the Industrial designation include Manufacturing (M) and Planned Manufacturing (PMD). Further the property is within Manufacturing Zoning District. The purpose of the “M” district is to provide for industrial uses and their related facilities while maintaining an environment free from objectionable noise, odor, dust or other nuisances.

General Plan Consistency. The General Plan has several land-use policies that are relevant to the proposed project. Table 5 presents an evaluation of the project’s consistency with applicable Placentia General Plan policies.

Table 5

Consistency with Placentia General Plan Policies

LU - 1.4: Preserve and improve industrial
uses that provide manufacturing
employment opportunities, through
infrastructure upgrades, enhanced
aesthetics, and new business
development strategies.

Consistent: The project is an infill
development that would serve to improve
an industrial vacant parcel of land for use
with an outdoor advertising display.

LU - 3.1: Encourage opportunities for
redevelopment and improvements in the
Old Town area, the TOD district, industrial
areas, neighborhoods in the southern
sector of the City, and commercial
centers along major roadway corridors.

Consistent: The project is an infill
development on a vacant industrial parcel
of land.

LU - 3.2: Support the provision of Consistent: The City of Placentia is working incentives for private development (as with Lamar Advertising Company on a appropriate), joint public privateDesign-Build-Operate-Maintain (DBOM) partnerships, and public improvements. Agreement to allow construction and ongoing operation and maintenance of a
double-sided freeway-oriented entry sign
with digital/static display capabilities on
City-owned property.
39 | Page
54 Proposed 1470 S. Placentia Billboard Project CEQA Class 32 Categorical Exemption Report LU -5.7: Promote exterior signage and
lighting that is subdued in character and
non-intrusive upon neighboring uses.

Consistent: The project would provide
lighting that is shielded to prevent spillage
onto neighboring properties and signage
will meet PMC standards. The proposed
project would respect the existing
neighborhood, and infrastructure
coordination will be required to lessen
impacts to adjacent parcels.

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

The project site is located within the City limits of Placentia. The triangular shaped

0.54-acre project site is bordered on the north by W. La Jolla Street, on the east by the Saddleback Gardens Planned Residential Development, to the south by SR-91 and to the west industrial development in the City of Anaheim. The proposed sign would be located on the embankment on the east side of the S. Placentia Avenue freeway overpass just northeast of the SR-91 freeway.

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

The subject site is an unimproved, vacant lot with a sparse covering of weeds and grasses along with a few small trees. It is located within a highly developed urban area that lacks habitat suitable for sensitive animal or plant species. This project location’s environment does not provide habitat for sensitive species due to its small size and highly urban context.

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

Based on the checklist contained in Section 2, the project will not result in significant effects relating to traffic, noise, air quality, or water quality.

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

The project would be located in an existing urban area served by existing public utilities and services. A substantial increase in demand for services or utilities would not be anticipated with implementation of the proposed project. Electrical services would continue to be provided to the proposed project by Southern California Edison, the existing service provider. Thus, the project meets this criterion for exemption.

Section 15300.2 Exceptions
State CEQA Guidelines Section 15300.2 requires a review for exceptions including hazardous waste sites, historic resources, scenic highways, cumulative effect and significant effects as a result of the project. 40 | Page
55 Proposed 1470 S. Placentia Billboard Project CEQA Class 32 Categorical Exemption Report A. HAZARDOUS WASTE SITES
State CEQA Guidelines Section 15300.2(e) states that “ a categorical exemption shall not be used for a project located on a site which is included on any list compiled pursuant to Section 65962.5 of the Government Code.”
The project site is not included on any list complied pursuant to Section 65962.5 of the Government Code. No impact will result. No mitigation measures are required.

B. HISTORIC RESOURCES
State CEQA Guidelines Section 15300.2(f) states that “a categorical exemption shall not be used for a project which may cause a substantial adverse change in the significance of a historical resource.”
T he project site is an unimproved, vacant lot. The project site is not known to be associated with events that have made a significant contribution to California’s history and cultural heritage nor with the lives of persons who have historic importance. The project site does not appear to be eligible for listing on the National Register of Historic Places or the California Register of Historical Resources, or for designation as a City landmark. The proposed project would not result in a substantial adverse change in the significance of a historic resource.

C. SCENIC HIGHWAYS
State CEQA Guidelines Section 15300.2(d) states that “a categorical exemption shall not be used for a project which 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 project is not adjacent to a designated state scenic highway or eligible state scenic highway as identified on the California Scenic Highway Mapping System. Thus, the proposed project would not damage the integrity of existing visual resources or historic buildings located along a State Scenic Highway. A less than significant impact on scenic resources, including but not limited to, trees, rock outcroppings, and historic buildings within a State Scenic Highway, would result. The project site is located in a developed, urbanized area, and contains no scenic resources. Due to the absence of on-site scenic resources, a less than significant impact would occur and no further analysis is required.

D. CUMULATIVE IMPACT
State CEQA Guidelines Section 15300.2(b) states that “all exemptions for these classes are inapplicable when the cumulative impact of successive projects of the same type in the same place, over time is significant.”
Cumulative impacts can result from the interactions of environmental changes resulting from one proposed project with changes resulting from other past, present, and future projects that affect the same resources, utilities and infrastructure systems, public services, transportation network elements, air basin, watershed, or other physical conditions. Such impacts could be short-term and temporary, usually consisting of overlapping construction impacts, as well as long term, due to the permanent land use changes involved in the project. The proposed project will generally result in less than significant environmental impacts, as discussed herein. Impacts related to traffic, noise, 41 | Page
56 Proposed 1470 S. Placentia Billboard Project CEQA Class 32 Categorical Exemption Report and water quality will be less than significant and therefore will not contribute substantially to any other concurrent construction programs that may be occurring in the vicinity. Short-term impacts related to pollutant emissions will be less than significant and will not exceed maximum thresholds.

The proposed project would not significantly cumulatively affect the environment. The proposed project would not result in any significant traffic impacts to transportation.

Long-term cumulative effects will have a less than significant impact on air quality.

Adherence to all conditions recommended, the cumulative impacts can be less than significant. The project would not contribute to any cumulative growth effects beyond what is anticipated for the City’s future in the General Plan.

E. SIGNIFICANT EFFECT
State CEQA Guidelines Section 15300.2(c) states that “a categorical exemption shall not be used for an activity where there is a reasonable possibility that the activity will have a significant effect on the environment due to unusual circumstances.” Based on the analysis of the proposed project’s impacts in the responses to items above, there is no indication that this project could result in substantial adverse effects on human beings. The land use requirements of this project would not directly or indirectly cause any substantial adverse effects on human beings. For this reason, the City has concluded that this project can be implemented without causing significant adverse environmental effects and determined that the Categorical Exemption (Class 32) is the appropriate type of CEQA documentation.

4. SUMMARY
Based on this analysis, the proposed 1470 S. Placentia Billboard meets all criteria for a Class 32 Categorical Exemption pursuant to Section 15332 of the State CEQA Guidelines and no exceptions are applicable.

Re: Lighting Analysis for Daktronics Light Mitigation 14' x 48' Orange County, City of Placentia, CA
Coordinates: 33.854138,-117.884624
The attached lighting analysis pertains to the digital display manufactured by Daktronics, Inc., and proposed for installation at Lamar Outdoor, Orange County, City of Placentia, CA. The following is an explanation of the analysis:
l. Units of Measurement. A foot-candle (or foot-candle, fc, lm/ft2, or ft-c) is a measurement of light intensity. One foot-candle is defined as enough light to saturate a one-foot square with one lumen of light. For example, where the display illuminates at 0.06 foot -candles, it has a light intensity of approximately 6% of a single wax candle as viewed from 1 foot away.

2. Assumptions: The accompanying graph depicts illumination levels in foot candles that the display will produce based on nighttime running levels at a measurement height of 75 feet in elevation. The measurements assume total darkness with regards to the surrounding light and an all-white content on the display. These assumptions provide for the worst-case scenario, not the more likely application.

3. Practical Application: Typical content runs at 25-35% of the brightness of all -white content, therefore, the actual levels of illumination will nearly always be markedly lower than that shown in the graph.

4. Ambient Light Effects. The presence of ambient light producing elements at night including, but not limited to, roadway and traffic lighting, commercial lighting from nearby commercial properties, the moon, etc., will further diminish the impact of the light output from the display in question.

5. Other Limiting Factors. The Daktronics digital display is equipped with a light sensor allowing for automatic dimming utilizing 256 levels of dimming. The display's dimming capabilities are designed to ensure that it does not exceed 0.3 foot candles above ambient light as measured from an appropriate distance from the sign. The 0.3 foot candles metric is a leading industry standard and has been adopted in numerous states and municipalities throughout the U.S.

6. Light Mitigation (DB7000LD ). The light mitigation technology has a +/-30 ° viewable area as seen on the East facing billboard . As an added benefit, the light impact at the residence located at 100' (directly below the display) will be reduced impact .

7. Standard (DB7000). The West facing billboard has a standard +/-80° viewable area. 63 DAKTRONICS.COM

; Please note, while the sign's brightness during daylight hours would be almost always incidental, there may be times in which the sign would produce illumination levels above ambient light during such hours. Examples when such an occurrence could happen would be during a very dark and stormy day. It is important to note, however, that the sign is equipped with a working photo -sensor that automatically adjusts its brightness based on ambient light. The photo-sensor adjusts the sign's brightness to lower levels, preventing the sign from appearing overly bright during those rare occasions where its brightness would exceed ambient light
