Policies Consistency Analysis
Growth Management Element
Policy GM-2.1: Maintain a
Level of Service “D” or
better along all City arterials
and at intersections during
peak hours.

Consistent. The proposed project would not adversely affect the level of service (LOS) of the project limits intersections, and would slightly improve traffic delays under current and future scenarios. Further, the proposed project would improve the existing traffic queuing issue and would ensure that queues do not exceed the storage capacities of the turn pockets in all but one turning scenario, which would improve the flow of traffic within the project limits.

Therefore, the proposed project would be consistent with Policy GM-2.1 of the City’s General Plan Growth Management Element.

Land Use Element
Policy LU-4.2: Promote an
attractive streetscape and
public right-of-way through
citywide drought
tolerant/low water use
landscape improvements
and maintenance.

Consistent. Although the proposed project would require vegetation removal in order to accommodate the proposed widening and other improvements, areas to be restored would be replicated with the previously present species. Areas of new landscaping would consist of drought tolerant trees, shrubs, perennials, and grasses pursuant to guidelines set forth by LMAD. Therefore, once the proposed project is operational, the project limits’ landscaped curb and median areas would contain attractive and drought tolerant streetscape features.

Therefore, the proposed project would be consistent with Policy LU-4.2 of the City’s General Plan Land Use Element.

Source: City of Yorba Linda General Plan (City of Yorba Linda, October 2016).

Though the YLTC Specific Plan does not set forth specific goals and policies that would be applicable to the proposed project, the proposed project would relieve congestion and improve mobility along Yorba Linda Boulevard as it intersects with Imperial Highway and Lakeview Avenue, and would therefore have positive effects on traffic circulation in the vicinity of the YLTC Specific Plan Area.

Therefore, the proposed project would be consistent with the YLTC Specific Plan.

Based on the analysis presented above, the proposed project would be consistent with all applicable land use plans, policies, and regulations, and impacts would be less than significant. No mitigation is required.

Would the project:

Impact Analysis
(a) Would the project result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the state?
No Impact. In 1975, the California Legislature enacted the Surface Mining and Reclamation Act (SMARA), which, among other things, provided guidelines for the classification and designation of mineral lands. Areas are classified on the basis of geologic factors without regard to existing land use and land ownership. The areas are categorized into four Mineral Resource Zones (MRZs):
• MRZ-1: An area where adequate information indicates that no significant mineral deposits are present, or where it is judged that little likelihood exists for their presence. • MRZ-2: An area where adequate information indicates that significant mineral deposits are present, or where it is judged that a high likelihood exists for their presence. • MRZ-3: An area containing mineral deposits, the significance of which cannot be evaluated. • MRZ-4: An area where available information is inadequate for assignment to any other MRZ zone.

Of the four categories, lands classified as MRZ-2 are of the greatest importance. Such areas are underlain by demonstrated mineral resources or are located where geologic data indicate that significant measured or indicated resources are present. MRZ-2 areas are designated by the State of California Mining and Geology Board as being “regionally significant.” Such designations require that a Lead Agency’s land use decisions involving designated areas are to be made in accordance with its mineral resource management policies and that it considers the importance of the mineral resource to the region or the State as a whole, not just to the lead agency’s jurisdiction.

As indicated in the City of Yorba Linda’s General Plan Conservation Element, the City contains mineral resources in the form of potential aggregate sources, which would be used as construction materials.
60 These materials are generally concentrated in MRZ-2 areas along the Santa Ana River, 60 City of Yorba Linda. 2016. General Plan Conservation Element. October. Website: https://www.yorba lindaca.gov/DocumentCenter/View/476/2016-GP-Conservation-Element?bidId= (accessed February 21, 2024).

which is located approximately 2.25 miles south of the project limits according to Exhibit CN-3 of the Conservation Element.

The City contains two specific Resource Sectors designated as Regionally Significant Aggregate by the California Department of Conservation Division of Mines and Geology. Both Resource Sectors are located near Featherly Regional Park and are not located within the vicinity of the project limits.

Further, the aggregate located within both Resource Sectors is unavailable because both areas were developed with land uses that preclude mining activities.

Therefore, development of the proposed project would not result in impacts related to the loss of availability of a known mineral resource that would be of value to the region and residents of the State, and no mitigation is required.
(b) Would the project result in the loss of availability of a locally important mineral resource recovery site delineated on a local general plan, specific plan or other land use plan? No Impact. As stated in Response 4.12(a), the area within the project limits is not considered a mineral resource zone containing any known valuable mineral resources or previously utilized as a mineral resource recovery site. Further, the City’s General Plan Conservation Element states that no active quarries exist within the City’s boundaries.61 Therefore, the proposed project does not contain any mineral resource recovery sites, and the proposed project would not result in the loss of availability of such a site. No impact would occur, and no mitigation is required. 61 City of Yorba Linda. 2016. General Plan Conservation Element. October.

Would the project result in:
(a) Generation of 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, or applicable standards of other
agencies?
(b) Generation of excessive groundborne vibration or
groundborne noise levels?
(c) For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within 2 miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels?
The analysis presented in the following section is based upon the Noise and Vibration Impact Analysis Memorandum (Noise Memo) prepared for the proposed project, which isincluded within this IS/MND as Appendix G.

Characteristics of Sound. Sound intensity is measured through the A-weighted scale to correct for the relative frequency response of the human ear. That is, an A-weighted noise level deemphasizes low and very high frequencies of sound similar to the human ear’s deemphasis of these frequencies.

Decibels (dB), unlike the linear scale (e.g., inches or pounds), are measured on a logarithmic scale, which is a scale based on powers of 10.

For example, 10 dB is 10 times more intense than 0 dB, 20 dB is 100 times more intense than 0 dB, and 30 dB is 1,000 times more intense than 0 dB. Thirty decibels (30 dB) represents 1,000 times as much acoustic energy as 0 dB. The decibel scale increases as the square of the change, representing the sound pressure energy. A sound as soft as human breathing is about 10 times greater than 0 dB.

The decibel system of measuring sound gives a rough connection between the physical intensity of sound and its perceived loudness to the human ear. A 10 dB increase in sound level is perceived by the human ear as only a doubling of the loudness of the sound. Ambient sounds generally range from 30 dB (very quiet) to 100 dB (very loud).

Sound levels are generated from a source, and their decibel level decreases as the distance from that source increases. Sound dissipates exponentially with distance from the noise source. For a single point source, sound levels decrease approximately 6 dB for each doubling of distance from the source.

This drop-off rate is appropriate for noise generated by stationary equipment. If noise is produced by a line source (e.g., highway traffic or railroad operations), the sound decreases 3 dB for each doubling of distance in a hard site environment; however, line source noise in a relatively flat environment with absorptive vegetation decreases 4.5 dB for each doubling of distance.

There are many ways to rate noise for various time periods, but an appropriate rating of ambient noise affecting humans also accounts for the annoying effects of sound. The equivalent continuous sound level (Leq) is the total sound energy of time-varying noise over a sample period. However, the

predominant rating scales for communities in the State of California are the Leq and Community Noise Equivalent Level (CNEL) or the day-night average noise level (Ldn) based on A-weighted decibels (dBA).

CNEL is the time-varying noise over a 24-hour period, with a 5 dBA weighting factor applied to the hourly Leq for noises occurring from 7:00 p.m. to 10:00 p.m. (defined as relaxation hours), and a 10 dBA weighting factor applied to noises occurring from 10:00 p.m. to 7:00 a.m. (defined as sleeping hours).

Ldn is similar to the CNEL scale but without the adjustment for events occurring during the evening hours.

CNEL and Ldn are within 1 dBA of each other and are normally interchangeable. The City of Yorba Linda uses the CNEL noise scale for long-term noise impact assessment.

Other noise rating scales of importance when assessing the annoyance factor include the maximum noise level (Lmax), which is the highest exponential time-averaged sound level that occurs during a stated time period. The noise environments discussed in this analysis for short-term noise impacts are specified in terms of maximum levels denoted by Lmax, which reflects peak operating conditions and addresses the annoying aspects of intermittent noise. Lmax is often used together with another noise scale, or noise standards in terms of percentile noise levels, in noise ordinances for enforcement purposes. For example, the L10 noise level represents the noise level exceeded 10 percent of the time during a stated period. The L50 noise level represents the median noise level. Half the time the noise level exceeds this level, and half the time it is less than this level. The L90 noise level represents the noise level exceeded 90 percent of the time and is considered the background noise level during a monitoring period. For a relatively constant noise source, the Leq and L50 are approximately the same.

Noise impacts can be described in three categories. The first category includes audible impacts that refer to increases in noise levels noticeable to humans. Audible increases in noise levels generally refer to a change of 3 dB or greater because this level has been found to be barely perceptible in exterior environments. The second category, potentially audible, refers to a change in the noise level between 1 dB and 3 dB. This range of noise levels has been found to be noticeable only in laboratory environments. The last category includes changes in noise levels of less than 1 dB, which are inaudible to the human ear. Only audible changes in existing ambient or background noise levels are considered potentially significant.

Existing Setting. The primary existing noise sources in the vicinity of the project limits are transportation facilities. Traffic on Yorba Linda Boulevard, Imperial Highway, and Lakeview Avenue is a steady source of ambient noise in the project vicinity. Land uses located adjacent to the intersections of Yorba Linda Boulevard and Imperial Highway and Yorba Linda Boulevard and Lakeview Avenue include primarily commercial uses; however, some residential uses also exist in the area.

Two long‐term (24‐hour) noise level measurements (LT‐1 and LT‐2) were conducted on January 10, 2024, using Larson Davis Spark 706RC dosimeters to document the existing noise environment within the project limits. Table 4.13.A summarizes the results of the long‐term noise level measurements along with a description of the measurement locations and noise sources that occurred during the measurements. As shown in Table 4.13.A, the calculated CNEL levels at LT‐1 and LT‐2 were 68.5 dBA and 68.8 dBA, respectively. In addition, the daytime noise levels ranged from 65.0 to 68.3 dBA Leq, evening noise levels ranged from 62.7 to 64.8 dBA Leq, and nighttime average noise levels ranged from 49.4 to 66.8 Leq. Also, the daytime maximum instantaneous noise levels ranged from 78.2 to 96.0 dBA, evening maximum instantaneous noise levels ranged from 78.2 to 83.7 dBA, and the nighttime maximum instantaneous noise levels ranged from 67.4 to 89.7 dBA.

Traffic Noise. The Federal Highway Administration (FHWA) Highway Traffic Noise Prediction Model (FHWA RD-77-108)62 was used to evaluate existing traffic-related noise conditions in the vicinity of the project limits. This model requires various parameters (including traffic volumes, vehicle mix, vehicle speed, and roadway geometry) to compute typical equivalent noise levels during daytime, evening, and nighttime hours. The resultant noise levels are weighted and summed over 24-hour periods to determine the CNEL values. The existing average daily traffic (ADT) volumes were obtained from the Yorba Linda Widening Traffic Impact Study63 prepared for the proposed project. The standard vehicle mix for Southern California roadways was used for traffic on these roadway segments. Table 4.13.B shows the existing traffic noise levels along Yorba Linda Boulevard in the project vicinity. These noise levels represent worst-case scenarios, which assume that no shielding is provided between the traffic and the location where the noise contours are drawn. The specific assumptions used in developing these noise levels and the model printouts are provided in Appendix G.

Impact Analysis
(a) Would the project result in generation of 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, or applicable standards of other agencies? Less Than Significant Impact.

Construction. Two types of short-term noise impacts would occur during project construction. The first type would be from construction crew commutes and the transport of construction equipment and materials to the project limits and would incrementally raise noise levels on roadways leading to the site. The pieces of construction equipment for construction activities would move on site, would remain for the duration of each construction phase, and would not add to the daily traffic volume in the project vicinity. Although there would be a relatively high single-event noise exposure potential causing intermittent noise nuisance (passing trucks at 50 feet would generate up to a maximum of 84 dBA), the effect on longer-term ambient noise levels would be small because the daily constructionrelated vehicle trips would be relatively small when compared to the existing daily traffic volume on Yorba Linda Boulevard. The grubbing and land clearing phase would generate the most trips of all the construction phases, at 777 trips per day based on the California Emissions Estimator Model (CalEEMod, Version 2022.1) in Appendix A to this IS/MND. Based on the Yorba Linda Widening Traffic Impact Study,
64 Yorba Linda Boulevard has an estimated existing ADT volume of 20,080 near the project limits. Based on the information above, construction‐related traffic would increase noise by up to 0.2 dBA. A noise level increase of less than 3 dBA would not be perceptible to the human ear in an outdoor environment. Therefore, no short-term construction-related impacts associated with worker commutes and transport of construction equipment and material to the project limits would occur, and no noise reduction measures would be required.

The second type of short-term noise impact is related to noise generated from construction activities.

Construction is performed in discrete steps, each of which has its own mix of equipment and, consequently, its own noise characteristics. The proposed project anticipates site preparation, grading, building construction, paving, and architectural coating phases of construction. These various sequential phases change the character of the noise generated on a project site. Therefore, the noise levels vary as construction progresses. Despite the variety in the type and size of construction 64 W.G. Zimmerman Engineering, Inc. (WGZE). 2024. Yorba Linda Widening Traffic Impact Study. January 31.

The site preparation phase, which includes excavation and grading of the site, tends to generate the highest noise levels because the noisiest construction equipment is earthmoving equipment.

Earthmoving equipment includes excavating machinery, such as backfillers, bulldozers, draglines, and front loaders. Earthmoving and compacting equipment includes compactors, scrapers, and graders.

Typical operating cycles for these types of construction equipment may involve 1 or 2 minutes of fullpower operation, followed by 3 or 4 minutes at lower power settings. 65 Federal Highway Administration (FHWA). 2006.

Construction of the proposed project is expected to require on-site use of bulldozers, front-end loaders, and water/pickup trucks. Noise associated with the use of construction equipment is estimated to be between 55 and 85 dBA Lmax at a distance of 50 feet from the active construction area during grading/ excavation. As shown in Table 4.13.C, the maximum noise level generated by each bulldozer is assumed to be approximately 85 dBA Lmax at 50 feet from the bulldozer. Each front-end loader would generate approximately 80 dBA Lmax at 50 feet. The maximum noise level generated by water trucks/pickup trucks is approximately 55 dBA Lmax at 50 feet from these vehicles. Each doubling of the sound source with equal strength increases the noise level by 3 dBA. Assuming that each piece of construction equipment operates at some distance from the other equipment, the worst-case combined noise level during this phase of construction would be 86 dBA Lmax at a distance of 50 feet from the active construction area. Based on a usage factor of 40 percent, the worst-case combined noise level during this phase of construction would be 82 dBA Leq at a distance of 50 feet from the active construction area.

The closest residence is located within 50 feet of the project construction area. Therefore, these receptor locations may be subject to short-term noise reaching 86 dBA Lmax (82 dBA Leq) or higher generated by construction activities in the project area. Although the noise generated by project construction activities would be higher than the ambient noise levels and would result in a temporary increase in the ambient noise levels, construction noise would stop once project construction is completed. Construction activities shall be limited to between the hours of 7:00 a.m. and 8:00 p.m. on weekdays, including Saturdays pursuant to Section 8.32.090(d) of the City’s Municipal Code. The implementation of construction hour limits would minimize construction noise. Therefore, noise generated from project construction activities would be less than significant.

Operation. The FHWA Highway Traffic Noise Prediction Model (FHWA-RD-77 108) 66 was used to
evaluate traffic-related noise conditions along Yorba Linda Boulevard. This model requires various parameters, including traffic volumes, vehicle mix, vehicle speed, and roadway geometry to compute typical equivalent noise levels during daytime, evening, and nighttime hours. The resultant noise levels are weighted and summed over 24-hour periods to determine the CNEL values. The existing (2023) and future (2025) ADT volumes were obtained from the Yorba Linda Widening Traffic Impact Study. 67 The standard vehicle mix for Southern California roadways was used for traffic on these roadway segments. Tables 4.13.D and 4.13.E show the existing (2023) and future (2025) traffic noise levels without and with the project, respectively. These noise levels represent the worst-case scenario, which assumes that no shielding is provided between traffic and the location where the noise contours are drawn.

As shown in Tables 4.13.D and 4.13.E, the project-related traffic noise on Yorba Linda Boulevard would increase by up to 0.4 dBA. Noise level increases below 3 dBA would not be perceptible to the human ear in an outdoor environment. Therefore, noise impacts from project-related traffic to off-site sensitive receptors would be less than significant, and no mitigation measures are required. 66 Federal Highway Administration (FHWA). 1977.

(b) Would the project result in generation of excessive groundborne vibration or groundborne noise levels?
Less Than Significant Impact.

Construction. Vibration generated by construction equipment can result in varying degrees of ground vibration, depending on the equipment. The operation of construction equipment causes ground vibrations that spread through the ground and diminish in strength with distance. Buildings on soil near an active construction area respond to these vibrations, which range from imperceptible to low rumbling sounds with perceptible vibrations and slight damage at the highest vibration levels.

Typically, construction-related vibration does not reach vibration levels that would result in damage to nearby structures.

The California Department of Transportation (Caltrans) Transportation and Construction Vibration Guidance Manual68 shows that the vibration damage threshold for continuous/frequent intermittent sources is 0.25 peak-particle velocity (PPV) (inches per second [in/sec]) for historic and old buildings.

The manual shows the vibration annoyance potential criteria to be barely perceptible at 0.01 PPV (in/sec), distinctly perceptible at 0.04 PPV (in/sec), and strongly perceptible at 0.10 PPV (in/sec) for continuous/frequent intermittent sources. These thresholds were used to evaluate the potential for short-term construction-related ground-borne vibration during construction of the proposed project.

The formula for vibration transmission is provided below. In the equation, D represents the distance of interest, PPVequip is the calculated peak particle velocity in units of in/sec of the construction equipment type at the distance of interest, PPVref is the reference vibration level for that type of construction heavy equipment in in/sec at the reference distance of 25 feet:

PPVequip = PPVref x (25/D)1.5
Bulldozers and trucks used for construction of the proposed project would generate the highest ground-borne vibration levels. Table 4.13.F shows the reference vibration levels at a distance of 25 feet for each type of standard construction equipment from the Caltrans Transportation and Construction Vibration Guidance Manual.
69 As shown in Table 4.13.F, the use of large bulldozers and loaded trucks associated with construction of the proposed project would generate ground-borne vibration levels of up to 0.089 PPV (in/sec) and

0.076 PPV (in/sec), respectively, when measured at 25 feet. The closest building structure is a commercial building approximately 15 feet from the project construction boundary that would experience vibration levels of up to 0.191 PPV (in/sec). Although this vibration level would be strongly perceptible, vibration levels would not exceed the damage threshold of 0.3 PPV (in/sec) because the condition of the commercial building would be equivalent to or better than older residential structures. Therefore, short-term construction impacts related to ground-borne vibration or groundborne noise would be less than significant. 68 California Department of Transportation (Caltrans). 2020.

Operation. Roads with smooth surface are not typically major sources of ground-borne noise or vibration. Ground-borne vibration is mostly associated with passenger vehicles and trucks traveling on roads with poor conditions, such as potholes, bumps, expansion joints, or other discontinuities in the road surface. Passenger vehicles and trucks would cause effects such as rattling of windows, and the sources are almost always airborne noise. The proposed project would include new asphalt pavement with proper maintenance. As a result, there would be no potholes, bumps, or other discontinuities in the road surface that would generate ground-borne vibration or noise impacts from vehicular traffic traveling on Yorba Linda Boulevard within the project limits. Therefore, ground-borne vibration and noise impacts generated by vehicles traveling on Yorba Linda Boulevard within the project limits would be less than significant. No mitigation measures are required. (c) For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within 2 miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? No Impact. The closest airport to the project limitsis Fullerton Municipal Airport, a commercial service airport located approximately 9.7 miles west of the project limits. Further, the project limits are located well beyond the 60 dBA CNEL airport noise contour and are not located within any airport impact zones based on the Airport Environs Land Use Plan (AELUP) for Fullerton Municipal Airport. 70 In addition, the proposed project is not located in the vicinity of a private airstrip. The proposed project is a transportation improvement project and would not involve the introduction of residential or employment uses in the project limits. Therefore, the project would not expose people residing or working in the project vicinity to aviation-related excessive noise levels, and no impacts would occur. 70 Airport Land Use Commission (ALUC). 2008.

elsewhere?
Impact Analysis
(a) Would the project induce substantial unplanned population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)?
No Impact. The proposed project would include various improvements to Yorba Linda Boulevard as it intersects with Imperial Highway and Lakeview Avenue in order to serve existing users of the roadway and does not propose any new inhabitable structures. The proposed project would not cause or result in direct population growth because the proposed project would not provide or remove housing on or nearby the project limits. The proposed project is not anticipated to generate any new permanent employment, though it would provide temporary employment throughout the duration of project construction.

Operation of the proposed project would not induce substantial population growth or accelerate development in an underdeveloped area, and no impacts to population growth would occur. No mitigation is required.
(b) Would the project displace substantial numbers of existing people or housing, necessitating the construction of replacement housing elsewhere?
Less Than Significant Impact. As previously stated, the project proposes to improve various roadway features of Yorba Linda Boulevard within the project limits. Partial property acquisitions associated with widening Yorba Linda Boulevard to accommodate the proposed intersection widening would affect seven parcels, consisting of Assessor’s Parcel Numbers (APNs) 334-391-07, 334-281-27, 348-161-01, 348-161-12, 348-161-13, 348-162-15, and 348-162-16. These parcels generally contain commercial establishments and associated parking facilities, and do not contain any residences.

Further, these partial acquisitions would affect small portions of each parcel and would not result in the demolition or repurposing of any existing structures. Because none of the affected parcels contain any housing units and existing commercial structures within the affected parcels would remain intact, the proposed project would not displace any housing or people, nor require or necessitate the development of replacement housing elsewhere. Impacts would be less than significant, and no mitigation would be required.

i. Fire protection?
Less Than Significant Impact. The Orange County Fire Authority (OCFA) is a Joint Powers Authority that serves the City of Yorba Linda and is responsible for reducing loss of lives and property from fire, medical, and environmental emergencies occurring within the City. OCFA provides fire protection, emergency medical and rescue services, hazardous materials inspection and response, and public education activities to its service area of 1,894,382 residents throughout 24 cities and unincorporated Orange County.71 OCFA Operations Division 4 includes Battalions 2 and 3, which are assigned to serve the Cities of Tustin, Villa Park, and Yorba Linda. The City of Yorba Linda is within the service area of Battalion 2. Currently, OCFA has a total of 78 stations, including two specialty stations, located throughout Orange County. OCFA Reserve Firefighters also work as part of ten different stations in Orange County. Three OCFA fire stations serve the City of Yorba Linda: Station 10, Station 32, and Station 53. The OCFA station located nearest the project limits is Fire Station 10, which is located less than 1,000 feet north of the project limits at 18422 Lemon Drive.72 The daily staffing of Station No. 10 71 Orange County Fire Authority (OCFA). 2023b.

includes 3 fire captains, 3 fire apparatus engineers, and 6 firefighters, and the total station staffing is 15 employees.
73 Fire Station 10 is served by Medic Engine 10 and Patrol 10.

In Fiscal Year 2023/2024, OCFA had 1,615 full-time equivalent uniformed and civilian personnel budgeted.74 The ratio of OCFA firefighters per 10,000 residents has remained steady over the past five fiscal years and has most recently been recorded as a ratio of 6.06.75 Over the past ten fiscal years, the emergency call load has increased by 62 percent, which was partially due to additional cities such as Garden Grove and Santa Ana joining the OCFA. According to OCFA’s 2022 Statistical Annual Report, OCFA responded to a total of 170,934 incidents throughout its service area, 130,653 of which were relayed to emergency medical services (EMS).76 Within the City of Yorba Linda, OCFA responded to 4,892 incidents, 3,744 of which were relayed to EMS.77
The proposed project consists of roadway improvements and would not increase employment or result in additional residents within the City. Therefore, project implementation would not trigger the need for new fire protection facilities. However, it should be noted that in order to accommodate the proposed widening of Yorba Linda Boulevard, three fire hydrants would be relocated during construction of the proposed project. The specific fire hydrants to be relocated are as follows:
• The fire hydrant on the south side of Yorba Linda Boulevard west of Imperial Highway in front of the Chili's Restaurant;
• The fire hydrant on the south side of Yorba Linda Boulevard in between Imperial Highway and Lakeview Avenue on the west side of the driveway into the Galleria de Yorba shopping center; and
• The fire hydrant on the south side of Yorba Linda Boulevard east of Lakeview Avenue in front of the Yorba Linda Palms Apartments.

However, these fire hydrants would be relocated in similar locations in order to align with the new curb alignment, and would not otherwise undergo any physical alterations. Once construction of the proposed project is complete, the three fire hydrants would continue to operate as they do under existing conditions. Therefore, the proposed project would not result in substantial adverse physical impacts associated with the provision of or need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain 73 City of Yorba Linda. 2016.

acceptable service ratios, response times, or other performance objectives for fire protection. Impacts would be less than significant, and no mitigation is required. ii. Police protection?
No Impact. The City of Yorba Linda contracts with the Orange County Sheriff’s Department (OCSD) for police protection services.78 OCSD provides 24-hour contract law enforcement services to the City, including the project limits. The Orange County Sheriff's Department consists of five organizational Commands comprised of 23 Divisions.79 The North Operations Division covers the City of Yorba Linda, in addition to the Cities of Stanton and Villa Park. The City of Yorba Linda Police Services building is located at 20994 Yorba Linda Boulevard, approximately 2.5 miles west of the project limits. In 2022, approximately 18,437 calls for police services were made within the City.

The proposed project consists of roadway improvements and would not increase employment or result in additional residents within the City. Therefore, project implementation would not trigger the need for new or physically altered police facilities. The proposed project would not result in substantial adverse physical impacts associated with the provision of or need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times, or other performance objectives for police protection. Therefore, the proposed project would have no impact to police facilities, and no mitigation is required.
iii. Schools?
No Impact. The Placentia-Yorba Linda Unified School District (PYLUSD) contains 34 school sites, including elementary (K–6), middle (7–8), high (9–12), and alternative schools, between the Cities of Yorba Linda, Placentia, Anaheim, Fullerton, and Brea.80 The student population of PYLUSD for the 2023–2024 school year was approximately 22,500 students.

Yorba Linda Boulevard serves as the attendance boundary for several schools within the PYLUSD. The closest PYLUSD elementary school to the proposed project is Mabel Paine Elementary School, located approximately 0.5 mile north of the project limits. According to the PYLUSD website, this elementary school feeds into Yorba Linda Middle School, located at 4777 Casa Loma Avenue approximately 0.6 mile west of the project limits. Yorba Linda Middle School then generally feeds into Yorba Linda High School, located at 19900 Bastanchury Road approximately 1.1 mile northeast of the project limits.

The proposed project consists of roadway improvements and would not increase employment or result in additional residents within the City. Therefore, the proposed project would not introduce any new school-age children to the project limits or the City, and would not trigger the need for new or physically altered school facilities.

The nearest park to the project limits is Richard Nixon Park, which consists of a lawn, trees, and a walking path. Richard Nixon Park is located directly north of the project limits, separated from Yorba Linda Boulevard by Mimi’s Café and a surface parking lot. The proposed project would not expand or otherwise physically alter Richard Nixon Park. Further, the proposed project consists of roadway improvements and would not increase employment or result in additional residents within the City.

Therefore, project implementation would not trigger the need for new or physically altered park facilities, including Richard Nixon Park. The proposed project would not result in substantial adverse physical impacts associated with the provision of or need for new or physically altered park facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable recreational opportunities for City residents. Therefore, the proposed project would have no impacts to park facilities, and no mitigation is required. v. Other public facilities?
No Impact. Implementation of the proposed project would not increase demand for other public services including libraries, community centers, and public health care facilities. As previously discussed, the proposed project consists of roadway improvements and does not include development of residential uses or a permanent increase in employment and would therefore not result in increased demand for other public facilities. Therefore, the proposed project would result in no impacts related to other public facilities, and no mitigation is required.

local parkland in order to meet the local neighborhood and community parkland standard, and identified several strategies for achieving this standard.

According to the map of recreational trails provided in Exhibit OR-2 of the City’s General Plan Open Space and Recreation Element, the project limits do not contain any trails, multipurpose trails, or County of Orange bicycle paths. Yorba Linda Boulevard within the project limits does not contain bicycle lanes in either direction.

The nearest recreational facility to the project limits is Richard Nixon Park, which consists of a lawn, trees, and a walking path. Richard Nixon Park is located directly north of the project limits, separated from Yorba Linda Boulevard by Mimi’s Café and a surface parking lot.

During construction of the proposed project, temporary delays may affect those using Yorba Linda Boulevard to access Richard Nixon Park. However, these impacts would be temporary and less than significant, as discussed in more detail in Section 4.17, Transportation.

As previously discussed, the proposed project does not include development of residential uses or a permanent increase in employment and would therefore not result in increased demand for recreational facilities, including neighborhood parks or regional parks. Further, because the proposed project would not contribute to a population increase, it would not accelerate substantial physical deterioration of nearby recreational facilities. As such, the proposed project would result in less than significant impacts to existing recreational facilities, and no mitigation is required. (b) Does the project include recreational facilities or require the construction or expansion of recreational facilities which might have an adverse physical effect on the environment? Less Than Significant Impact. As discussed in Section 4.15, Public Services, in Response 4.15(a)(iv), the project limits are adjacent to one existing recreational facility within the City: Richard Nixon Park.

Richard Nixon Park would not be affected by the property acquisitions necessitated by the proposed project. While no changes to Richard Nixon Park are proposed under the project, temporary construction-related lane closures may occur but would not result in significant adverse impacts pertaining to access to recreational facilities within the City including Richard Nixon Park.

Further, the proposed project would not develop any new recreational facilities that would require the construction or expansion of existing recreational facilities that might have an adverse effect on the environment. Therefore, impacts to recreation facilities would be less than significant, and no mitigation is required.

This section is based on the information presented in both the Traffic Impact Study and the Yorba Linda Boulevard Traffic Operations Study, prepared for the proposed project by W.G. Zimmerman Engineering, Inc. in January 2024. These documents are included as Appendix H to this IS/MND.

Impact Analysis
(a) Would the project conflict with a program plan, ordinance or policy addressing the circulation system, including transit, roadway, bicycle and pedestrian facilities? Less Than Significant Impact. As stated in Section 4.11, Land Use and Planning, of this IS/MND, the proposed project would be required to comply with the Orange County Congestion Management Program (CMP), which identifies Imperial Highway as part of the CMP Highway System. 86 However,
there are no specific CMP requirements for roadway segment monitoring.87 Further, Figure 5, Summary of Conformance, in the Orange County CMP, states that no CMP intersections currently exist within the City of Yorba Linda. Based on this, and the fact that the proposed project would ultimately contribute to the achievement of traffic congestion reduction goals set forth in the CMP, the proposed project would be consistent with the Orange County CMP.

The proposed project would be required to comply with the City’s General Plan goals and policies addressing the circulation system, including transit, roadway, bicycle, and pedestrian facilities. The Circulation Element of the City of Yorba Linda General Plan guides the development of the City's circulation system in a manner that supports the citywide objectives of the General Plan.

As previously stated, the City’s General Plan Circulation Element classifies Yorba Linda Boulevard as a Modified Major Arterial between the western city limit and Fairmont Boulevard. This type of roadway provides six travel lanes with a daily capacity of 56,300 vehicles at a modified right-of-way width of 86 Orange County Transportation Authority (OCTA). 2023. 2023 Orange County Congestion Management Program Report. November. Website: https://www.octa.net/pdf/2023CMP.pdf?n=202311 (accessed March 13, 2024). 87 City of Yorba Linda. 2016. General Plan Circulation Element. October.

100 feet. Due to this relatively narrow right-of-way, the roadway does not contain any bicycle lanes and does not permit on-street parking. An Orange County Transportation Authority (OCTA) bus stop is located along the northern curb of Yorba Linda Boulevard, just west of the roadway’s intersection with Imperial Highway. This bus stop would be shifted to meet the proposed roadway realignment, but would not experience any adverse effects once the proposed project is operational.

Other roadways to be affected by the proposed project are Imperial Highway and Lakeview Avenue.

Imperial Highway is classified as a Smart Street with six lanes north of Yorba Linda Boulevard and four lanes south of Yorba Linda Boulevard. North of Yorba Linda Boulevard, the curb-to-curb street width is approximately 90 feet, with three lanes in both directions with a dual left-turn lane and a shared through/right-turn lane at the intersection. South of the intersection, the street width is approximately 84 feet, with two lanes in each direction with a left-turn lane and a shared through/ right-turn lane at the intersection. Parking is not allowed on the street, and there is a raised concrete median that separates each direction of traffic.

Lakeview Avenue is a four-lane (two lanes in each direction) facility. North of Yorba Linda Boulevard, Lakeview Avenue has a curb-to-curb width of 70 feet and is classified as a Secondary Arterial and south of the intersection, it is classified as a Primary Arterial. The lane geometrics consist of two lanes in each direction with dual left turns northbound and southbound at the intersection. Parking is not allowed on the street, and there are Class II Bike Lanes north of the intersection.

Level of Service (LOS) is a qualitative measure of the effect of traffic flow factors, such as speed, travel time, interruptions, freedom to maneuver, driver comfort, and convenience. The City has established Level of Service (LOS) D as the threshold or lowest acceptable level of roadway and intersection operation for planning purposes.88 The criteria for LOS used in the following analysis are based on the ICU (intersection capacity utilization) methodology for signalized intersections which categorizes Level of Service by the V/C ratio (volume to capacity) of the intersection, which is the methodology presented in the City’s Circulation Element to explain the various LOS ratings, as follows:
• Level A – V/C ratio of 0.00–0.60. Primarily free-flow conditions at average travel speeds. Vehicles are seldom impeded in their ability to maneuver in the traffic stream. Delays at intersections are minimal.
• Level B – V/C ratio of 0.61–0.70. The control delay ranges from 10 to 15 seconds per vehicle.

Unimpeded operations at average travel speeds. The ability to maneuver in the traffic stream is slightly restricted; delays are not bothersome.
• Level C – V/C ratio of 0.71–0.80. The control delay ranges from 15 to 25 seconds per vehicle.

Stable operations; however, ability to change lanes and maneuver may be more restricted than LOS B, and longer queues are experienced at intersections. 88 City of Yorba Linda. 2016.

• Level D – V/C ratio of 0.81–0.90. The control delay ranges from 25 to 35 seconds per vehicle.

Congestion occurs and a small change in volume increases delays substantially. • Level E – V/C ratio of 0.91–1.00. Severe congestion occurs with extensive delays accompanied by low travel speeds.
• Level F – V/C ratio greater than 1.00. Extremely low speeds and intersection congestion occurs with high delays and extensive queuing.

Existing peak hour traffic volumes are based upon morning and evening peak period intersection turning movement counts obtained from Counts Unlimited on November 30, 2022, during typical weekday conditions. The morning peak period was collected between 7:00 AM and 9:00 AM and the evening peak period was collected between 4:00 PM and 6:00 PM. These traffic volume counts were used to evaluate the intersections’ existing and future LOS within the project limits. The primary measures of evaluation include LOS and delay. The study intersections’ LOS were calculated using Synchro software, which is based on the Highway Capacity Manual method for signalized and unsignalized intersections. The AM and PM peak hour LOS were calculated based on the following conditions:
• Existing conditions (2023)
• Existing conditions (2023) plus project
• Future conditions (2025)
• Future conditions (2025) plus project
Table 4.17.A summarizes the results of the existing weekday morning and evening peak hour V/C ratio and corresponding LOS at each intersection. As shown in Table 4.17.A, the proposed project is forecasted to result in no significant traffic impact at the study intersections, as both intersections experience no change in LOS in the Existing Plus Project scenario, and even experience slight delay improvements.

As shown in Tables 4.17.A, 4.17.B, and 4.17C, the proposed project would not adversely affect the LOS of the intersections within the project limits, and would actually slightly improve traffic delays under the existing and future scenarios. Further, the proposed project would improve the existing traffic queuing issue and would ensure that queues do not exceed the storage capacities of the turn pockets in all but one turning scenario. As such, the proposed project would be consistent with the LOS metrics and other circulation-related goals set forth in the City’s General Plan Circulation Element.

Based on the analysis presented above, the proposed project would not conflict with plans addressing the circulation system of the project limits. The proposed project’s impacts to adopted plans, policies, or regulations would be less than significant, and no mitigation is required.

(b) Would the project conflict or be inconsistent with CEQA Guidelines §15064.3, subdivision (b)? Less Than Significant Impact. On September 27, 2013, Governor Jerry Brown signed Senate Bill (SB) 743 into law, which directed the Governor’s Office of Planning and Research (OPR) to establish new CEQA guidance for jurisdictions that remove the level of service (LOS) method, which focuses on automobile vehicle delay and other similar measures of vehicular capacity or traffic congestion, from CEQA transportation analysis. Rather, vehicle miles traveled (VMT), or other measures that promote “the reduction of greenhouse gas emissions, the development of multimodal transportation networks, and a diversity of land uses,” are now used as the basis for determining significant transportation impacts in the State.

As part of a January 2018 update to the State CEQA Guidelines, Section 15064.3 codifies that projectrelated transportation impacts are typically best measured by evaluating the project’s VMT.

Specifically, subdivision (b) focuses on specific criteria related to transportation analysis. Subdivision (b)(2) addresses VMT associated with transportation projects and states that projects that reduce VMT, such as pedestrian, bicycle, and transit projects, should be presumed to have a less than significant impact. Subdivision (b)(4) stipulates that lead agencies have the discretion to formulate a methodology that would appropriately analyze a project’s VMT. The City of Anaheim Traffic Impact Analysis Guidelines for California Environmental Quality Act Analysis89 and the City of Yorba Linda Traffic Impact Analysis Guidelines90 establish thresholds for land development projects, but do not establish thresholds for transportation projects. However, the State provides sufficient guidance to evaluate transportation project impacts related to VMT.

The Technical Advisory on Evaluating Transportation Impacts in CEQA (Technical Advisory) published by the Governor’s Office of Planning and Research in December 2018 states the following:

Projects that would not likely lead to a substantial or measurable increase in vehicle travel, and therefore generally should not require an induced travel analysis, include [in addition to various other examples]:
• Roadside safety devices or hardware installation such as median barriers and guardrails.
• Installation, removal, or reconfiguration of traffic lanes that are not for through traffic, such as left, right, and U-turn pockets, two-way left-turn lanes, or emergency breakdown lanes that are not utilized as through lanes. 91 89 City of Anaheim. 2020.

The proposed project would realign Yorba Linda Boulevard and modify the existing median to facilitate the construction of a second eastbound left-turn lane at the roadway’s intersections with Imperial Highway and Lakeview Avenue. Both left-turn lanes would be approximately 125 feet in length providing 250 feet of storage compared to 135 feet in the existing condition. Westbound Yorba Linda Boulevard at the roadway’s intersection would be modified to provide dual left-turn lanes and preserve the alignment of westbound lanes across the intersection. An exclusive eastbound right-turn lane approximately 275 feet in length would also be constructed as part of the project. No additional through lane capacity is proposed under the project.

In summary, the proposed project would create three additional turn lanes: a second eastbound leftturn, a second westbound left-turn, and an exclusive eastbound right-turn. The proposed project would therefore be considered as the installation or reconfiguration of traffic lanes that are not for through capacity. The three additional turn lanes address queueing and stacking issues and would not add through capacity to Yorba Linda Boulevard, which would continue to provide six through lanes west of Lakeview Avenue. As such, the proposed project would not likely lead to a substantial increase in vehicle travel and would not require an induced travel analysis, according to the OPR Technical Advisory. As such, the proposed project is exempt from requiring a detailed VMT analysis, and impacts pertaining to Section 15064.3 of the State CEQA Guidelines would be less than significant. No mitigation is required.
(c) Would the project substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? Less Than Significant Impact. As stated above in Response 4.17(b), the proposed project would reduce queuing and stacking issues within the project limits through the proposed turn lane additions and roadway realignment. Under current conditions, the closely spaced intersections within the project limits face an existing safety issue of spillover from turn lane traffic into through lanes. The proposed project would therefore reduce the presence of hazards within the project limits. Further, the proposed project would include partial acquisitions of parcels surrounding the project limits in order to accommodate the additional space needed for the proposed road widening and ensure that the no potentially hazardous sharp curves or turns are introduced to the project limits.

Aside from the improvements discussed above, the proposed project would continue existing roadway uses and would not introduce any new incompatible land uses. No new hazardous geometric design features or incompatible land uses would be included as part of the proposed project. Based on the preceding information, impacts related to increased hazards due to a geometric design feature or incompatible uses would be less than significant, and no mitigation is required. (d) Would the project result in inadequate emergency access? Less Than Significant Impact. Under current conditions, Yorba Linda Boulevard has two closely spaced intersections, with Imperial Highway and Lakeview Avenue. The signalized intersection of Imperial Highway/Yorba Linda Boulevard is located approximately 500 feet west of the signalized intersection of Lakeview Avenue/Yorba Linda Boulevard. Driveways for shopping areas west of Imperial Highway create further closely spaced intersections along Yorba Linda Boulevard. As a result, limited space is available to provide storage for turning movements and stacking can occur, which would impede emergency access. As previously stated, the proposed project would reduce queuing and stacking

issues within the project limits through the proposed turn lane additions and roadway realignment.

Therefore, once the proposed project is operational, emergency access along Yorba Linda Boulevard, Imperial Highway, and Lakeview Avenue would be equivalent to or improved compared to existing conditions.

The proposed project would achieve continued mobility along Yorba Linda Boulevard during the construction phase through the use of temporary lane closures and lane shifts. These shifts could result in temporary delays but would allow the roadway to remain open the entire duration of the proposed project’s construction. Therefore, the proposed project’s impacts to emergency vehicle access would be less than significant. No mitigation is required.

Impact Analysis
Assembly Bill (AB) 52 requires meaningful consultation with California Native American Tribes on potential impacts to tribal cultural resources, as defined in Public Resources Code (PRC) Section 21074 as sites, features, places, cultural landscapes, sacred places, and objects with cultural value to a California Native American tribe that are eligible for inclusion in the California Register of Historical Resources or included in a local register of historical resources. Per PRC Section 21080.3.1, a tribe must submit a written request to the relevant lead agency if it wishes to be notified of proposed projects in its traditionally and culturally affiliated area. Lead agencies must provide written formal notification to the tribes that have requested it within 14 days of determining that a project application is complete or of deciding to undertake a project. The tribe must respond to the lead agency within 30 days of receipt of the notification if it wishes to engage in consultation on the project, and the lead agency must begin the consultation process within 30 days of receiving the request for consultation. Consultation concludes when either (1) the parties agree to mitigation measures to avoid a significant effect, if one exists, on a tribal cultural resource, or (2) a party, acting in good faith and after reasonable effort, concludes that mutual agreement cannot be reached. AB 52 also addresses confidentiality during tribal consultation per PRC Section 21082.3(c). (a) Would the project cause a substantial adverse change in the significance of a tribal cultural resource, defined in Public Resources Code Section 21074 as either a site, feature, place, cultural landscape that is geographically defined in terms of the size and scope of the landscape, sacred place, or object with cultural value to a California Native American tribe, and that is:

Less Than Significant with Mitigation Incorporated. The Native American Heritage Commission (NAHC) is a State agency that maintains the Sacred Lands File (SLF), an official list of sites that are of cultural and religious importance to California Native American tribes. The NAHC was contacted on October 10, 2023, in order to request a SLF search for the project limits, as well as a list of potential Native American contacts for consultation. The NAHC responded on November 27, 2023, stating that the SLF search returned positive results for the project limits. The NAHC also provided a list of suggested Native American contacts for consultation outreach efforts.

In compliance with AB 52, letters have been distributed to the 13 Native American tribal contacts identified by the NAHC in its inquiry response dated November 27, 2023. The letters, which were sent via certified mail on December 15, 2023, provided each tribe with an opportunity to request consultation with the City regarding the proposed project. The purpose of this effort was to provide Native American tribes with the opportunity for meaningful participation and to identify known tribal cultural resources on or near the project limits. Please refer to Table 4.18.A below for a list of recipients of the letters sent on December 15, 2023. The record of tribal consultation efforts is included as Appendix I to this IS/MND.

In compliance with AB 52, the tribes had 30 days from the date of receipt of notification to request consultation on the proposed project. Information provided through the AB 52 tribal consultation process typically informs the assessment as to whether tribal cultural resources are present within the project limits and the significance of any potential impacts to such resources. A response was received from Andrew Salas, Chairperson of the Gabrieleño Band of Mission Indians - Kizh Nation, on December 20, 2023. In this response, Chairperson Salas requested to initiate consultation with the City regarding the proposed project. A consultation meeting was held between representatives of the Gabrieleño Band, the City, and the City’s consultants on February 22, 2024. The meeting concluded with the understanding that that consultation would remain open throughout the design and construction of the proposed project.

No other responses were received from the 12 other individuals listed in Table 4.18.A below, and no other requests for consultation were received prior to the close of the 30-day period. A follow-up message was sent via email to the tribal contacts on January 10, 2024, providing an additional invitation to consult with the City regarding the proposed project. No responses to this follow-up email have been received to date. As such, no tribal cultural resources have currently been identified within or in the vicinity of the project limits. However, ongoing coordination between the City of Yorba Linda and the Gabrieleño Band of Mission Indians - Kizh Nation will continue throughout future stages

of the proposed project, including construction. Specifically, during construction of the proposed project, a representative from the Gabrieleño Band of Mission Indians - Kizh Nation would be present within the project limits to monitor ground-disturbing activities, as set forth in Mitigation Measure (MM) TCR-1, detailed below.

Further, as discussed in Section 4.5, Cultural Resources, of this IS/MND, no known cultural resources have been documented within the project limits or in the direct vicinity of the proposed project based on archival research and a pedestrian field survey. Further, low potential exists for the proposed project to impact tribal cultural resources due to significant prior disturbance from past grading and development activities within the project limits and in the surrounding area. Regulatory Compliance Measure (RCM) CUL-1, identified in Section 4.5, sets forth procedures for handling inadvertent discoveries of human remains, including those determined to be Native American. MM TCR-1 would set forth procedures for monitoring of ground-disturbing activities associated with the proposed project by a Tribal representative.

Adherence to RCM CUL-1 and MM TCR-1 would ensure that impacts related to the inadvertent discovery of Native American cultural resources or human remains would be less than significant.

With this adherence, and based on the fact that tribal consultation efforts did not yield any

information regarding the presence of tribal cultural resources within the project limits, impacts to tribal cultural resources would be less than significant, and no mitigation is required.

Mitigation Measure
MM TCR-1 Prior to issuance of a grading permit, the City of Yorba Linda Public Works Department shall retain a Native American Monitor prior to commencement of ground-disturbing activities:

A. The City of Yorba Linda Public Works Department shall retain a Native American Monitor from or approved by the Gabrieleño Band of Mission Indians – Kizh Nation (Kizh Nation). The monitor shall be retained prior to the commencement of any “grounddisturbing activity” for the project at all project locations (i.e., both on-site and any off-site locations that are included in the project description/definition and/or required in connection with the project, such as public improvement work). “Grounddisturbing activity” shall include, but is not limited to, demolition, pavement removal, potholing, auguring, grubbing, tree removal, boring, grading, excavation, drilling, and trenching.

B. A copy of the executed monitoring agreement shall be submitted to the lead agency prior to the commencement of any grounddisturbing activity, or the issuance of any permit necessary to commence a ground-disturbing activity, whichever is earlier.

C. The monitor shall complete daily monitoring logs that will provide descriptions of the relevant ground-disturbing activities, the type of construction activities performed, locations of ground-disturbing activities, soil types, cultural-related materials, and any other facts, conditions, materials, or discoveries of significance to the Kizh Nation. Monitor logs shall identify and describe any discovered TCRs, including but not limited to, Native American cultural and historical artifacts, remains, places of significance, etc., (collectively, tribal cultural resources, or “TCRs”), as well as any discovered Native American (ancestral) human remains and burial goods. Copies of monitor logs shall be provided to the lead agency upon written request to the Kizh Nation.

D. On-site tribal monitoring shall conclude upon the latter of the following: (1) written confirmation to the Kizh Nation from a designated point of contact for the lead agency that all grounddisturbing activities and phases that may involve grounddisturbing activities within the project limits or in connection with the project are complete; or (2) a determination and written

Water. A majority of the City of Yorba Linda is served by the Yorba Linda Water District (YLWD), but small portions are served by Golden State Water Company.92 The project limits fall within the service boundaries of the YLWD, which is a non-profit agency licensed by the State Water Resources Control Board (SWRCB).93 In June 2021, the YLWD updated its Urban Water Management Plan and Water Shortage Contingency Plan to submit to the California Department of Water Resources (DWR) to satisfy the Urban Water Management Plan (UWMP) Act of 1983 (UWMP Act) and subsequent 92 City of Yorba Linda. n.d.

California Water Code (Water Code) requirements. UWMPs are comprehensive documents that present an evaluation of a water supplier’s reliability over a long-term (20–25 year) horizon. 94 According to the UWMP, the YLWD’s main source of water supply is groundwater from the Lower Santa Ana River Groundwater Basin,95 comprising approximately 53 percent of the supply mix. The remaining 47 percent is imported from sources including the Colorado River and the State Water Project, which is provided to the YLWD by the Metropolitan Water District of Southern California. It is projected that by 2045, the YLWD’s water supply mix will consist of approximately 85 percent groundwater and 15 percent imported water.96
According to the UWMP, the City’s projected water supply will be able to meet 100 percent of the projected water demand in 2025, 2030, 2035, 2040, and 2045.97 Therefore, the City’s existing water supplies are projected to meet full service demands through the year 2045.

The proposed project would not result in any new land uses that would consume water or generate wastewater. Water would be used during construction to reduce fugitive dust in compliance with SCAQMD Rules 402 and 403 and during operation for irrigation of landscaped curb areas. Landscaping for the project limits, which would include drought-tolerant species, would not represent a substantial increase in water used for irrigation in comparison to existing conditions in the project limits.

Further, the proposed project would be required to comply with Chapter 16.12, Water Efficient Landscape Regulations, of the City’s Municipal Code. The proposed project would satisfy requirement (A)(2) under Section 16.12, Applicability, as it would consist of landscape rehabilitation and contains an aggregate landscaped area of 2,500 square feet or more. As such, the proposed project would be subject to the landscape water use standards set forth in Chapter 16.12, which would ensure that the proposed project would not involve inefficient use of water supply.

The amount of water used during construction and operation would be minimal, and water use for construction would cease when construction is completed. Therefore, the proposed project would not require or result in the construction of new water treatment facilities or the expansion of existing facilities.

In order to accommodate the proposed road widening, several water infrastructure features would be relocated, including the following:

• The water valves, and water meters on the south side of Yorba Linda Boulevard west of Imperial Highway in front of the Chili's Restaurant;
• The underground backflow preventer on the south side of the Yorba Linda Boulevard west of Imperial Highway in the grassy area in front of the Chili's Restaurant; • The YLWD water enclosure and valve on the south side of Yorba Linda Boulevard east of the driveway to the Firestone Village shopping center; and
• The water meter on the south side of Yorba Linda Boulevard east of Lakeview Avenue in front of the Yorba Linda Palms Apartments.

However, it is anticipated that these facilities would be relocated to similar locations along the new curb and median alignments, and would not mark a substantial change from existing conditions that could cause a significant environmental effect. Therefore, once the proposed project is operational, impacts to existing water and water treatment facilities as a result of the proposed project would be less than significant.

Wastewater. In addition to providing water services to the City as discussed above, the YLWD maintains the nearly 150 miles of sewer systems within the City.98 Wastewater collected within the City is conveyed by this sewer system to the Orange County Sanitation District (OC San) trunk sewer line for treatment and disposal. Once conveyed to the OC San system, wastewater flows by gravity to the OC San Reclamation Plant No. 1 in Fountain Valley for treatment. 99 Reclamation Plant No. 1 treats
wastewater using advanced primary and secondary treatment and supplies secondary-treated water to the Orange County Water District, which further treats and distributes the water for various uses, including groundwater recharge.

As stated previously, the proposed project includes improvements to an existing roadway. None of the components of the proposed project would introduce wastewater-generating uses to the project limits. As such, development of the proposed project would not contribute to the wastewater received by the City’s wastewater infrastructure or the OC San Reclamation Plant No. 1. The proposed project therefore would not require, nor would it result in, the construction or relocation of new or expanded wastewater treatment or collection facilities, and no impact would occur.

Stormwater and Drainage Facilities. The City of Yorba Linda Department of Public Works is responsible for the maintenance of the City’ storm drain system, as well as the design and construction of new storm drain infrastructure. The City’s storm drain system flows directly to local creeks and rivers, including the Santa Ana River, and ultimately discharge into the Pacific Ocean. 98 City of Yorba Linda. 2016.

Implementation of the proposed project would increase the impervious surface area within the project limits by approximately 0.13 acre, which would result in a slight increase in stormwater runoff from the project limits. With implementation of the proposed project, any curb inlets affected by the proposed curb shift or road widening would be replaced along the new alignment to ensure that drainage properties within the project limits is not adversely affected. Specifically, the existing catch basin on the north side of Yorba Linda Boulevard west of Imperial Highway in front of the Mimi’s Café Restaurant would be shifted to align with the proposed curb position. Therefore, the proposed project would not decrease the capacity of the existing stormwater drainage system through the permanent removal of any drainage facilities. As such, the curb inlets identified in Section 4.10, Hydrology and Water Quality, of this IS/MND would continue to accommodate runoff water originating from the project limits. As previously discussed, the project limits currently consist of a roadway already developed with predominantly impervious surface area and the proposed project would result in a nominal increase of surface runoff in comparison to existing conditions. Therefore, the proposed project would not necessitate the expansion of existing facilities beyond the improvements included as part of the proposed project. Therefore, impacts to stormwater drainage facilities would be less than significant. No mitigation is required.

Electric Power. The City, and the project limits, are located within the service territory of Southern California Edison (SCE). In order to accommodate the proposed road widening, several electrical infrastructure features would be relocated, including transformers, electrical vaults, and electrical cabinets. Specifically, the following features would be relocated:
• The transformer on the north side of Yorba Linda Boulevard west of Imperial Highway in the grassy area south of Mimi's Café;
• Street lights along Yorba Linda Boulevard;
• The traffic signal poles and their associated pull boxes, cabinets, and lines at the northwestern, southwestern, and southeastern corners of the intersection of Yorba Linda Boulevard and Imperial Highway and at the southwestern and southeastern corners of the intersection of Yorba Linda Boulevard and Lakeview Avenue;
• The junction box on the south side of Yorba Linda Boulevard east of Imperial Highway in front of the El Pollo Loco drive-through;
• The SCE vault on the south side of Yorba Linda Boulevard east of Imperial Highway in front of the Galleria de Yorba sign;
• The electrical vault on the south side of Yorba Linda Boulevard west of Lakeview Avenue in front of the T-Mobile;
• The SCE vault on the south side of Yorba Linda Boulevard east of Lakeview Avenue and west of the driveway into the Firestone Village shopping center; • The SCE Cabinet on the south side of Yorba Linda Boulevard east of the driveway to the Firestone Village shopping center;

However, it is anticipated that these facilities would be relocated to similar locations along the new curb and median alignments, and would not mark a substantial change from existing conditions that could cause a significant environmental effect.

Please refer to Section 4.6, Energy, for more background information regarding the proposed project’s electricity use. As discussed in Section 4.6, the proposed project involves roadway improvements and therefore would not increase the demand for electricity when compared to existing site conditions.

Therefore, the proposed project would not require or result in the construction of new or expanded electric power facilities, and impacts would be less than significant.

Natural Gas. Natural gas for the City of Yorba Linda is provided by Southern California Gas Company (SoCalGas). SoCalGas provides natural gas services to around 21.1 million consumers across 500 communities.100
The proposed project consists of roadway improvements, and no natural gas usage would occur as a result of construction or operation of the proposed project. Therefore, the proposed project would not require or result in the relocation or construction of new or expanded natural gas facilities, and no impact would occur.

Telecommunication Facilities. Cable, internet, and telephone services are provided to the City’s residents by major third-party purveyors. Cellular services provided by all major cellular networks are available in the City. Construction activities associated with the proposed project would not increase the demand for telecommunications facilities. In addition, the proposed project would not involve the construction or relocation of new or expanded telecommunications facilities. Further, the proposed roadway improvements do not propose any habitable structures and would not introduce any new residents to the telecommunications service area. Therefore, implementation of the proposed project would not result in impacts related to the construction or relocation of existing telecommunications facilities, and no mitigation would be required.
(b) Would the project have sufficient water supplies available to serve the project and reasonably foreseeable future development during normal, dry and multiple dry years? No Impact. Refer to the Water subsection of Response 4.19(a), above. As discussed, water use during construction and operation would be minimal, and water supplies for construction activities would be temporary in nature, ceasing upon construction completion. In addition, the minor increase in water use during operation for irrigation would not require additional entitlements or resources. Further, the YLWD UWMP states that projected water supplies will be able to meet 100 percent of projected 100 Southern California Gas (SoCalGas). n.d. Company Profile.

service area water demand in 2025, 2030, 2035, 2040, and 2045.101 Therefore, the City’s existing water supplies are projected to meet full service demands through the year 2045. Further, construction and operation of the proposed improvements would not affect existing water supply infrastructure or require expansion of such infrastructure, and no impact would occur. (c) Would the project result in a determination by the wastewater treatment provider which serves or may serve the project that it has adequate capacity to serve the project’s projected demand in addition to the provider’s existing commitments?
No Impact. Refer to the Wastewater subsection of Response 4.19(a), above. The proposed project consists of roadway improvements and would not introduce any new sources of wastewater. No wastewater would be generated as a result of construction or operation of the proposed project.

Therefore, the project would not require or result in the construction of new wastewater treatment facilities or the expansion of existing facilities, and no impact would occur. (d) Would the project generate solid waste in excess of State or local standards, or in excess of the capacity of local infrastructure, or otherwise impair the attainment of solid waste reduction goals? Less Than Significant Impact. The proposed project would consist of roadway improvements and would generate minimal waste throughout operations. However, the proposed project would generate construction waste that would require processing in local recycling facilities and disposal in local landfills.

Waste and recycling services within the City of Yorba Linda are provided exclusively by Republic Services as part of a Citywide Franchise Agreement that became effective in April 2015.102 Republic Services provides waste, recycling, and compost collection and disposal services to the City’s residents.

The closest Orange County landfill to the project limits is the Olinda Alpha Landfill, located approximately 3.4 miles northwest of the project limits at 1942 Valencia Avenue in Brea. Solid waste/refuse collected in the City by Republic Services is transported to the Olinda Alpha Landfill, a Class III Sanitary Landfill owned and operated by Orange County Waste & Recycling. The Olinda Alpha Landfill spans 565 acres and has a projected capacity to serve Orange County until approximately 2030. Its maximum permitted solid waste intake is 8,000 tons per day (TPD) and its average rate is 7,000 TPD.103
Chapter 8.20.080 of the City’s Municipal Code requires any person generating solid waste in connection with construction and demolition activities to arrange for solid waste collection by Republic Services or be registered to self-haul.

is to reuse or recycle at least 65 percent of project-related waste.104 Therefore, the proposed project’s construction-related waste would be appropriately hauled and a majority of the waste would be diverted from the Olinda Alpha Landfill. Further, the solid waste generation estimate for the operation of the proposed project would have a negligible contribution to the daily tonnage processed at the Prima Deshecha Landfill.

Based on the capacity and maximum permitted solid waste intake of the Olinda Alpha Landfill, it would provide adequate waste disposal services to accept construction waste and minimal operations waste generated by the proposed project, and project impacts to local solid waste standards and infrastructure would be less than significant. No mitigation is required. (e) Would the project comply with federal, State, and local management and reduction statutes and regulations related to solid wastes?
No Impact. As discussed in Response 4.19(d), waste generated during construction of the proposed project would generally be limited to construction debris and would not generate an excessive amount of solid waste that would exceed the capacity of the Olinda Alpha Landfill.

Many federal, State, and local waste management regulations would not apply to the proposed project because they pertain to organic waste, building demolition debris, and other elements that would not be present under the proposed project. As previously discussed, Section 8.20.080 of the City’s Municipal Code regulates construction-related solid waste collection and requires that the waste be collected by Republic Services or self-hauled in accordance with the self-hauling standards laid out in Chapter 8.20. Further, the City’s Building Division mandates that all projects that include demolition prepare a Construction Waste Management Plan (CWMP) and verify that at least 65 percent of project waste has been recycled or enlist Republic Services for collection prior to permit issuance. Because the proposed project would involve approximately 161,627 square feet of road and pavement demolition, it would be required to comply with these local regulations.

Construction waste would be disposed of in accordance with federal, State, and local regulations related to solid waste, including the California Integrated Waste Management Act of 1989 (Assembly Bill [AB] 939), which requires each jurisdiction in California to divert at least 50 percent of its waste stream away from landfills either through waste reduction, recycling, or other means.105 Further, waste collected during maintenance of the roadway, once the proposed project is operational, would be collected and disposed of consistent with City policies. Therefore, the proposed project would comply with all federal, State, and local statutes and regulations related to solid waste, and no impact would occur.

The following response addresses Thresholds 4.20(a), (b), (c), and (d), as outlined above.

No Impact. The California Department of Forestry and Fire Protection (CAL FIRE) has mapped areas of significant fire hazards in the State through its Fire and Resources Assessment Program (FRAP). These maps place areas of California into different fire hazard severity zones (FHSZ), based on a hazard scoring system using subjective criteria for fuels, fire history, terrain influences, housing densities, and occurrence of severe fire weather where urban conflagration could result in catastrophic losses. As part of this mapping system, CAL FIRE is responsible for wildland fire protection for land areas that are generally unincorporated and they are classified as State Responsibility Areas (SRAs). In areas where local fire protection agencies (e.g., Orange County Fire Authority [OCFA]) are responsible for wildfire protection, the lands are classified as Local Responsibility Areas (LRAs). CAL FIRE currently identifies the project limits, and the City of Yorba Linda in its entirety, as a Local Responsibility Area,

The project limits are located within a developed area and the proposed project would not introduce any new habitable structures or include any characteristics that would impair emergency response or evacuation or which would expose occupants to increased risks resulting from a wildfire.

Improvements proposed under the project include road widening, median and curb modifications, restriping, utility relocations, and construction of a new retaining wall. However, these features would not substantially increase the scale of the project limits’ development from existing conditions, and would not exacerbate the fire risk of the project limits. Further, the project limits are generally flat, within an urbanized portion of the City, and lack combustible materials and vegetation necessary for the uncontrolled spread of a wildfire. Overall, due to the project limits’ characteristics and distance from the nearest VHFHSZ, the proposed project would have no impacts related to wildfire. No mitigation is required.

(a) Does the project have the potential to substantially degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, substantially reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the
major periods of California history or prehistory?
(b) Does the project have impacts that are individually limited, but cumulatively considerable? (“Cumulatively
considerable” means that the incremental effects of a
project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects?) (c) Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly?
Impact Analysis
(a) Does the project have the potential to substantially degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, substantially reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory? Less Than Significant with Mitigation Incorporated. The project limits are located in a developed urban environment characterized by a variety of residential, commercial, and transportation land uses. As discussed previously in the Chapter 4.0 sections of this IS/MND, development of the proposed project would not have the potential to degrade the quality of the natural environment.

As discussed in Section 4.4, Biological Resources, no special-status species have been observed within the project limits and are not anticipated to be present due to lack of suitable habitat and/or conditions. The existing landscaped median and curb areas contain ornamental landscaping and nonnative trees, which could potentially support nests and roosting for bird species. With the implementation of Regulatory Compliance Measures (RCMs) BIO-1 through BIO-3, potential impacts to nesting birds, roosting bats, and trees would ensure that the proposed project would not degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self‐sustaining levels, threaten to eliminate a plant or animal community, or reduce the number or restrict the range of a rare or endangered plant or animal.

It is not anticipated that the proposed project would eliminate important examples of the major periods of California history or prehistory because the project limits has been previously disturbed when the existing roadway and adjacent urban development were completed, and the likelihood of

encountering significant historic or prehistoric artifacts during grading, excavation, and site development activities would be minimal. To ensure that potential impacts to undiscovered paleontological resources remain less than significant, preparation of a Paleontological Resources Impacts Mitigation Program, paleontological monitoring of construction activities, appropriate treatment of newly discovered resources, and preparation of a final paleontological monitoring report would be required, as outlined in Mitigation Measure (MM) GEO-1. To ensure that potential impacts to undiscovered tribal cultural resources remain less than significant, a Native American monitor associated with the Gabrieleño Band of Mission Indians – Kizh Nation (Kizh Nation) would be retained during ground-disturbing activities pursuant to MM TCR-1. Additionally, construction contractors are required to adhere to California Code of Regulations (CCR) Section 15064.5(e), Public Resources Code (PRC) Section 5097, and Section 7050.5 of the State’s Health and Safety Code, ensuring proper treatment of burials in the event of an unanticipated discovery of a burial, human bone, or suspected human bone. The law requires that all excavation or grading in the vicinity of the find halt immediately, the area of the find be protected, and the contractor immediately notify the County Coroner of the find. Therefore, the proposed project would not eliminate important examples of the major periods of California history or prehistory. Overall, the City’s implementation of compliance measures and mitigation measures as part of the project would minimize the impacts on the environment as indicated throughout this environmental analysis, and the project’s impacts would be considered less than significant.
(b) Does the project have impacts that are individually limited, but cumulatively considerable? (“Cumulatively considerable” means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects?)
Less Than Significant Impact. The project limits are located in a fully developed urban environment characterized by a variety of residential, commercial, and transportation land uses. In the existing condition, the project limits are currently developed with the Yorba Linda Boulevard roadway. As discussed in Section 4.11, Land Use and Planning, of this IS/MND, the proposed project would be consistent with the City’s circulation goals and policies and therefore cumulative land use impacts would be less than significant. Further, Section 4.17, Transportation, reiterates that the proposed project would reduce delays and would not have adverse level of service (LOS) or vehicle miles traveled (VMT) impacts; therefore, the proposed project would not conflict with plans addressing the circulation of the project limits and would therefore not contribute to cumulative LOS delays or VMT.

As described in Section 4.3, Air Quality, the proposed project would be consistent with the South Coast Air Quality Management District (SCAQMD) Air Quality Management Plan (AQMP) and would not result in air quality impacts that would be considered cumulatively considerable. As described in Section 4.8, Greenhouse Gas Emissions, the proposed project would not generate greenhouse gas (GHG) emissions that would have a significant impact on the environment and would not conflict with any GHG-related plans; therefore, GHG emissions generated by the proposed project would not be cumulatively considerable.

In addition, impacts from the proposed project related to aesthetics, biological resources, cultural resources, energy, hazards and hazardous materials, hydrology and water quality, noise, public services, recreation, and utilities and service systems would be less than significant and therefore would not result in cumulatively considerable impacts.

The proposed project would not have any impacts related to agriculturalresources, mineralresources, population and housing, and wildfire, and would therefore not have any cumulatively significant impacts related to these topics.

Impacts from the proposed project related to geology and soils and tribal cultural resources can be reduced to a less than significant level with mitigation. Therefore, the proposed project would not cumulatively contribute to significant impacts related to these environmental topics.

In summary, the proposed project would maintain and improve the existing Yorba Linda Boulevard roadway and does not propose any features that would substantially change the site’s current characteristics or cause significant adverse environmental effects. Therefore, impacts from the proposed project would not be cumulatively considerable. (c) Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly?
Less Than Significant Impact. The project limits contain an existing roadway located in a fully developed urban environment characterized by a variety of residential, commercial, and transportation land uses. Development of the proposed project would not be expected to result in adverse impacts to human beings, either directly or indirectly. As such, impacts to human beings are not expected to occur, and a less than significant impact would result.

5.0 MITIGATION MONITORING AND REPORTING PROGRAM

5.1 MITIGATION MONITORING REQUIREMENTS
Public Resources Code (PRC) Section 21081.6 (enacted by the passage of Assembly Bill 3180) mandates that where significant effects have been identified, the following requirements shall apply to all reporting or mitigation monitoring programs:
• The public agency shall adopt a reporting or monitoring program for the changes made to the project or conditions of project approval in order to mitigate or avoid significant effects on the environment. The reporting or monitoring program shall be designed to ensure compliance during project implementation. For those changes that have been required or incorporated into the project at the request of a responsible agency or a public agency having jurisdiction by law over natural resources affected by the project, that agency shall, if so requested by the lead agency or a responsible agency, prepare and submit a proposed reporting or monitoring program. • The lead agency shall specify the location and custodian of the documents or other materials that constitute the record of proceedings upon which its decision is based. • A public agency shall provide measures to mitigate or avoid significant effects on the environment that are fully enforceable through permit conditions, agreements, or other measures. Conditions of project approval may be set forth in referenced documents that address required mitigation measures or, in the case of the adoption of a plan, policy, regulation, or other project, by incorporating the mitigation measures into the plan, policy, regulation, or project design. • Prior to the close of the public review period for a Draft Initial Study/Mitigated Negative Declaration (IS/MND), a responsible agency, or a public agency having jurisdiction over natural resources affected by the project, shall either (1) submit to the lead agency complete and detailed performance objectives for mitigation measures that would address the significant effects on the environment identified by the responsible agency or agency having jurisdiction over natural resources affected by the project, or (2) refer the lead agency to appropriate, readily available guidelines or reference documents. Any mitigation measures submitted to a lead agency by a responsible agency or an agency having jurisdiction over natural resources affected by the project shall be limited to measures that mitigate impacts to resources that are subject to the statutory authority of, and definitions applicable to, that agency. Compliance or noncompliance with that requirement by a responsible agency or agency having jurisdiction over natural resources affected by a project shall not limit the authority of the responsible agency or agency having jurisdiction over natural resources affected by a project, or the authority of the lead agency, to approve, condition, or deny projects as provided by this division or any other provision of law.

RCM BIO-1 Construction Activity. If possible, vegetation removal should be avoided during the nesting bird season (February 1–August 31). If nesting bird season is unavoidable, prior to construction activities, including vegetation removal, a pre-construction nesting bird survey will be conducted by a qualified biologist no more than 3 days (72 hours) prior to any construction activities and vegetation removal. Should nesting birds be found, an exclusionary buffer will be established by the qualified biologist. The buffer will be clearly marked in the field by construction personnel under guidance of the qualified biologist. No construction activities will be allowed within this zone until the qualified biologist determines that the young have fledged, or the nest is no longer active.

RCM BIO-3 Night Work Lighting. If possible, night work should be avoided during the nesting bird season (February 1–August 31). If night work (i.e., between dusk and dawn) is anticipated within 100 feet of an active bird nest and/or nest exclusionary buffer, night lighting will be used only in areas of active work and focused on the direct area(s) of work and away from nesting locations to the greatest extent practicable. The qualified biologist may adjust the exclusionary buffer size to decrease the possibility of disturbance by night work, if warranted. This measure would minimize disturbance and prevent nest failure. If birds are showing signs of distress, such as flushing from their nests, work activities shall be modified to prevent the nest from being abandoned.

SUBJECT: AUTHORIZATION TO BEGIN PREPARATIONS FOR THE 2025 JULY 4TH

FIREWORKS SHOW

RECOMMENDATION
It is recommended that the City Council direct staff to initiate planning efforts for the 2025 July 4th Fireworks Show and authorize staff to execute payment to Pyro Spectaculars, Inc. in an amount not-to-exceed $35,226.

BACKGROUND
Since 1989, the City of Yorba Linda has conducted the July 4th Spectacular on the day of the holiday. The festivities take place at Yorba Linda Middle School and Veterans Park and culminate with a fireworks display. Staff recommends contracting with Pyro Spectaculars because they are recognized as the premier fireworks company in the industry. The City of Yorba Linda has contracted with Pyro Spectaculars for all but one of the fireworks shows since the inception of this event.

DISCUSSION
Pyro Spectaculars, Inc. requires a partial payment to ensure we are placed on their busy July 4th calendar. A deposit in the amount of $17,613 and signed agreement is due by April

1. The City Manager is authorized in the City’s purchasing policy to execute the agreement; however, this event will take place in the next fiscal year.

FISCAL IMPACT
The total cost for this event is projected at $110,000. This includes all program costs consisting of personnel, equipment, fireworks, stage, sound, lighting, and live entertainment.

Staff will request funding for the event during the budget process for fiscal year 25/26.

ALTERNATIVES
The alternative is for the City Council to not authorize staff to begin planning for the July 4th Fireworks Show, not approve payment to Pyro Spectacular, and direct staff to either cancel the event or develop an alternate plan to celebrate Independence Day.

3.3 Expenses – PYRO shall pay all normal expenses directly related to the Production including freight, insurance as outlined, pyrotechnic products, pyrotechnic equipment, experienced pyrotechnic personnel to set up and discharge the pyrotechnics and those additional items as outlined as PYRO’s responsibility in the Scope of Work. CLIENT shall pay all costs related to the Production not supplied by PYRO including, but not limited to, those items outlined as CLIENT’s responsibility in this Agreement and Scope of Work.

4. Proprietary Rights - PYRO represents and warrants that it owns all copyrights, including performance rights, to this Production, except that PYRO does not own CLIENT-owned material or third-party-owned material that has been included in the Production, and as to such CLIENT-owned and third-partyowned material, CLIENT assumes full responsibility therefore. CLIENT agrees that PYRO shall retain ownership of, and all copyrights and other rights to, the Production, except that PYRO shall not acquire or retain any ownership or other rights in or to CLIENT-owned material and third-party-owned material and shall not be responsible in any way for such material. If applicable, CLIENT consents to the use of CLIENT-owned material and represents that it has or will obtain any permission from appropriate third parties sufficient to authorize public exhibition of any such material in connection with this Production.

6. Security - CLIENT shall provide adequate security personnel, barricades, and Police Department services as may be necessary to preclude individuals other than those authorized by PYRO from entering an area to be designated by PYRO as the area for the set-up and discharge of the Production, including a fallout area satisfactory to PYRO where the pyrotechnics may safely rise and any debris may safely fall.

8. Permits - PYRO agrees to apply for permits for the firing of pyrotechnics only from the Orange County Fire Authority, FAA, and USCG, if required. CLIENT shall be responsible for any fees associated with these permits including standby fees. CLIENT shall be responsible for obtaining any other necessary permits, paying associated fees, and making other appropriate arrangements for Police Departments, other Fire Departments, road closures, event/activity or land use permits or any permission or permit required by any Local, Regional, State or Federal Government.

9. Insurance - PYRO shall at all times during the performance of services herein ensure that the following insurance is maintained in connection with PYRO’s performance of this Agreement: (1) commercial general liability insurance, including products, completed operations, and contractual liability under this Agreement; (2) automobile liability insurance, (3) workers’ compensation insurance and employer liability insurance. Such insurance is to protect CLIENT from claims for bodily injury, including death, personal injury, and from claims of property damage, which may arise from PYRO’s performance of this Agreement, only. The types and amounts of coverage shall be as set forth in the Scope of Work. Such insurance shall not include claims which arise from CLIENT’s negligence or willful conduct or from failure of CLIENT to perform its obligations under this Agreement, coverage for which shall be provided by CLIENT.

The coverage of these policies shall be subject to reasonable inspection by CLIENT. Certificates of Insurance evidencing the required general liability coverage shall be furnished to CLIENT prior to the rendering of services hereunder and shall include that the following are named as additionally insured: CLIENT; Sponsors, Landowners, Barge Owners, if any; and Permitting Authorities, with respect to the operations of PYRO at the Production. Pyrotechnic subcontractors or providers, if any, not covered under policies of insurance required hereby, shall secure, maintain and provide their own insurance coverage with respect to their respective operations and services.

10. Indemnification - PYRO represents and warrants that it is capable of furnishing the necessary experience, personnel, equipment, materials, providers, and expertise to produce the Production in a safe and professional manner. Notwithstanding anything in this Agreement to the contrary, PYRO shall indemnify, hold harmless, and defend CLIENT and the additional insureds from and against any and all claims, actions, damages, liabilities and expenses, including but not limited to, attorney and other professional fees and court costs, in connection with the loss of life, personal injury, and/or damage to property, arising from or out of the Production and the presentation thereof to the extent such are occasioned by any act or omission of PYRO, their officers, agents, contractors, providers, or employees. CLIENT shall indemnify, hold harmless, and defend PYRO from and against any and all claims, actions, damages, liability and expenses, including but not limited to, attorney and other professional fees and court costs in connection with the loss of life, personal injury, and/or damage to property, arising from or out of the Production and the presentation thereof to the extent such are occasioned by any act or omission of CLIENT, its officers, agents, contractors, providers, or employees. In no event shall either party be liable for the consequential damages of the other party.

11. Limitation of Damages for Ordinary Breach - Except in the case of bodily injury and property damage as provided in the insurance and indemnification provisions of Paragraphs 9 and 10, above, in the event CLIENT claims that PYRO has breached this Agreement or was otherwise negligent in performing the Production provided for herein, CLIENT shall not be entitled to claim or recover monetary damages from PYRO beyond the amount CLIENT has paid to PYRO under this Agreement, and shall not be entitled to claim or recover any consequential damages from PYRO including, without limitation, damages for loss of income, business or profits.

12. Force Majeure - CLIENT agrees to assume the risks of weather, strike, civil unrest, terrorism, military action, governmental action, and any other causes beyond the control of PYRO which may prevent the Production from being safely discharged on the scheduled date, which may cause the cancellation of any event for which CLIENT has purchased the Production, or which may affect or damage such portion of the exhibits as must be placed and exposed a necessary time before the Production. If, for any such reason, PYRO is not reasonably able to safely discharge the Production on the scheduled date, or at the scheduled time, or should any event for which CLIENT has purchased the Production be canceled as a result of such causes, CLIENT may (i) reschedule the Production and pay PYRO such sums as provided in Paragraph 13, or (ii) cancel the Production and pay PYRO such sums as provided in Paragraph 14, based upon when the Production is canceled.

13. Rescheduling Of Event - If CLIENT elects to reschedule the Production, PYRO shall be paid the original Fee plus all additional expenses made necessary by rescheduling plus a 15% service fee on such additional expenses. Said expenses will be invoiced separately and payment will be due in full within 5 days of receipt. CLIENT and PYRO shall agree upon the rescheduled date taking into consideration availability of permits, materials, equipment, transportation and labor. The Production shall be rescheduled for a date not more than 90 Days subsequent to the date first set for the Production. The Production shall not be rescheduled to a date, or for an event, that historically has involved a fireworks production. The Production shall not be rescheduled between June 15th and July 15th unless the original date was July 4th of that same year, or between December 15th and January 15th unless the original date was December 31st of the earlier year unless PYRO agrees that such rescheduling will not adversely affect normal business operations during those periods.

14. Right To Cancel – CLIENT shall have the option to unilaterally cancel the Production prior to the scheduled date. If CLIENT exercises this option, CLIENT agrees to pay to PYRO, as liquidated damages, the following percentages of the Fee as set forth in Paragraph 3.1. 1) 50% if cancellation occurs 30 or more days prior to the scheduled date, 2) 75% if cancellation occurs 15 to 29 days prior to the scheduled date, 3) 100% thereafter. In the event CLIENT cancels the Production, it will be impractical or extremely difficult to fix actual amount of PYRO’s damages. The foregoing represents a reasonable estimate of the damages PYRO will suffer if CLIENT cancels the Production.

TO: HONORABLE MAYOR AND MEMBERS OF THE CITY COUNCIL
FROM: NATE FARNSWORTH, COMMUNITY DEVELOPMENT DIRECTOR
PREPARED BY: JIM SOWERS, CBO
SUBJECT: DEMOLITION PERMIT REQUEST FOR 16612 LOIE STREET

RECOMMENDATION
It is recommended that City Council approve the demolition permit request for 16612 Loie Street.

BACKGROUND
The City has received a request for a partial demolition of an existing single-family dwelling located at 16612 Loie Street. The existing structure is a single story, 2,239 square foot residence with 3-bedrooms, 2-baths and a 564 square foot attached garage. The residence is wood framed construction with stucco, and brick veneer, and located on a 0.43-acre lot.

The applicant is proposing to demolish approximately 80% of the existing exterior walls and 100% of interior walls. The project also has an existing 300 square foot detached doghouse located on the west side yard, which is scheduled for demolition. This property is currently connected to the Yorba Linda public sewer system, Southern California Edison and Southern California Gas.

The new plan includes a 1020 square foot addition, with a 545 square foot garage, and a new foundation system to support the proposed construction. There will be an attempt to reuse portions of the existing foundation for the rebuild the existing home and blend the foundation into a cohesive unit.

DISCUSSION
In accordance with the City Council’s P-4 policy, the demolition permit has been analyzed to determine whether there is any historic significance with the existing property. The existing residence is a single story 2,239 square foot home. The structure was built in 1961, according to the 2010 City Wide Historic Resources Survey. The home does not reflect any historical significance. Prior to permit issuance, a demolition request will be reviewed by the Engineering Division for compliance with storm water prevention as well as compliance with best management practices. Additionally, an asbestos survey will be performed, and if the findings are positive, appropriate abatement measures will be required, and the South Coast Air Quality Management District notified.

SUBJECT: DENIAL OF CLAIM FOR DAMAGES- ADNAN NAQVI, SHERRI NAQVI,

ESTATE OF NOAH HUSAIN NAQVI AND SETTLEMENT REQUEST FOR

HERBERT WARREN

RECOMMENDATION
It is recommended that the City Council of the City of Yorba Linda deny the claims for damages filed by Adnan Naqvi, Sherri Naqvi, and the Estate of Noah Husain Naqvi, and settle the claim for damages filed by Herbert Warren.

BACKGROUND
Claims for damages filed against the City are reviewed and investigated by City staff and a third-party claims administrator with George Hills Company, Inc. George Hills Company specializes in claims management and risk management services. These services are provided through the City’s contract membership in the California Insurance Pool Authority.

City staff make recommendations to the Council for settlement or denial based on the investigatory findings. A claimant’s failure to provide evidence of and/or supporting documents to substantiate the claim for damages will also result in a recommendation for denial of the claim.

DISCUSSION
The following claims for damages have been recommended for denial based on the investigations by City staff and the third-party claims administrator. Further details for each claim are available upon request.

Adnan Naqvi, Sherri Naqvi, and Estate of Noah Husain Naqvi The City has received three wrongful death claims arising from a traffic collision on Yorba Linda Boulevard. The incident involved a motorcyclist operating a 2024 Kawasaki ZX6R eastbound in the #3 lane of Yorba Linda Boulevard and a 2004 Chevy Pickup traveling westbound in the unraised center median. The pickup turned left across eastbound traffic to enter a private apartment complex and was struck by the motorcyclist. The motorcyclist

HUSAIN NAQVI AND SETTLEMENT REQUEST FOR HERBERT WARREN
P a g e | 2
sustained catastrophic injuries that led to their death. The claimants allege that a dangerous condition of public property contributed to the vehicle accident. Specific concerns include inadequate roadway design, insufficient sight distance, improper speed limitations, and lane widths that fail to safely accommodate left-turning motor vehicle traffic.

The third-party claims administrator and City staff recommend denying these claims and issuing a Rejection Notice to the claimant’s attorneys. This action will formally commence the six-month statute of limitations for any further legal action.

Herbert Warren
The following claim for damages is recommended for settlement based on investigations conducted by City staff and the third-party claims administrator.

The claimant alleges that their vehicle was rear-ended by a City vehicle at Kellogg Drive near the Yorba Linda Country Club golf course. The accident investigation confirms the allegation, including that a City employee operating a City vehicle in the course and scope of their employment caused the collision.

The claimant seeks a total of $5,846.76 in damages. After reviewing the claim and the supporting documentation, the third-party claims administrator and City staff recommend that the City Council approve settlement authority to resolve the claim.

FISCAL IMPACT
Acceptance of the Herbert Warren claim will result in a fiscal impact of $5,846.76.

ALTERNATIVES
As an alternative to staff’s recommendations for the denial of the claims, the City Council has the following options:

1. Accept liability for the claims and pay the amount specified in the claim forms.

2. Grant settlement authority up to a certain amount and direct the claims adjuster to enter into settlement negotiations with the claimants.

STATE ROUTE 73 CATALINA VIEW IMPROVEMENTS PROJECT

COOPERATIVE AGREEMENT
The San Joaquin Hill Transportation Corridor Agency (SJHTCA) Board of Directors authorized Transportation Corridor Agencies’ (TCA) CEO to execute an agreement with California Department of Transportation (Caltrans) for the State Route (SR) 73 Catalina View Improvements Project Initiation Document phase and Project Approval and Environmental Document phase.

The SR 73 Catalina View Improvements Project is part of the Boards’ adopted Fiscal Year 2025 Capital Improvement Plan as a proposed capital project, anticipated to be completed by 2030. To advance the project development and meet the 2030 delivery schedule, a cooperative agreement with Caltrans is necessary to engage Caltrans staff in project development efforts.

OUTGOING BOARD MEMBER RECOGNITION
SJHTCA Chair Janine Heft and Director Farrah Kahn were honored at the December Board Meeting for their leadership and service on the Boards of Directors.

Chair Heft has represented the city of Laguna Hills since 2018, generously serving as Vice Chair and Chair of the SJHTCA, as well as on numerous committees – chairing the Toll Operations Committee and serving as a member of the Joint Finance and Investment Committee, Strategic Planning Committee, Environmental Committee, and External Affairs Committee.

Director Kahn has served on the Boards of Directors of the SJHTCA and the Foothill/Eastern Transportation Corridor Agency (F/ETCA) as the representative from the City of Irvine since 2021, and served as a member on several committees, including the Joint Capital Programs and Projects Committee, Joint Strategic Planning Committee, Joint Toll Operations Committee, Joint External Affairs Committee, and the Joint Finance and Investment Committee.

F/ETCA Chair Taylor, along with CEO Ryan Chamberlain thanked both Directors for their leadership and unwavering commitment to regional mobility and public service to the people of Orange County.

COMMUNITY ENGAGEMENT ACTIVITIES REACH OVER 240,000 RESIDENTS Staff presented TCA’s community outreach efforts for 2024. The Community Engagement team has been active in member cities as part of the Boards’ adopted Strategic Plan.

Since the beginning of 2024, the Community Engagement team hosted booths at 48 regional events, attended 165 city and chambers of commerce meetings, attended member city state of the city events, and provided monthly updates about The Toll Roads at various community meetings with an estimated public attendance of over 240,000 people.

Communications and public engagement are a focus for the Agencies and one of the key pillars of the Strategic Plan.

At events, staff engages with the community to address questions, provides information on upcoming projects and programs, and gathers feedback to improve overall communications. Page 510 of 1177 CEO UPDATES AND 2024 HIGHLIGHTS
CEO Chamberlain shared an upcoming Request for Information (RFI) set to be released by the end of the year for the Toll Plaza Reuse Plan. As a result of a shift to all-electronic tolling in 2014, the current TCA toll plazas are no longer in use. The Toll Plaza Reuse Request for Information is part of the Boards’ approved Strategic Plan initiative to explore other concepts for the underutilized space. The RFI request will be distributed to several bid-engine platforms and TCA staff with work with stakeholders to review.

During the Board Meeting, CEO Chamberlain also shared a Year in Review video showcasing the Agencies’ notable progress, milestones, and achievements in 2024. The video can be viewed here.

When completed, this new tolled facility will provide drivers with a direct connection between the 241 Toll Road and the 91 Express Lanes, helping to improve traffic flow on the 241 Toll Road and in the general-purpose lanes on SR91. The project is a multi-agency collaboration between TCA, California Department of Transportation (Caltrans), Orange County Transportation Authority (OCTA), and Riverside County Transportation Commission (RCTC).

Ms. Blanco highlighted that significant progress has been made over the past year with project partners, noting that the next major milestone will be the execution of the project’s Master and Operational agreements in spring 2025.

NATIONWIDE PHISHING SCAM UPDATE
CEO Ryan Chamberlain provided an update to the Boards of Directors about the nationwide phishing scam where California tolling agencies, including TCA, have been recently targeted by scammers sending fraudulent text messages to the public attempting to collect outstanding tolls. The texts claims that an individual owes FasTrak® charges, links to a website and asks for online payment. This scam is designed to deceive drivers into entering banking or credit card information into a website. In response, TCA staff has deployed a communications campaign to inform consumers of the scam and the necessary steps to report the fraudulent activity to the FBI’s Internet Crime Complaint Center at www.ic3.gov.

TCA, as with most toll operators, does not send text messages to customers demanding payment, and does not send text messages to non-accountholders. If the public receives a text like this, do not click on the links and treat it as a phishing scam.

South Coast Air Quality Management District Newsletter Fall 2024 Carlos Rodriguez
Cities of Orange County
Governing Board Member
Welcome to my newsletter for the residents and businesses of Orange County. My goal is to help
keep you informed about the policies
and programs at South Coast AQMD
that improve the air quality in our basin.

If you have suggestions for improving
air quality, or on how we do business at
South Coast AQMD, please feel free to
contact me at
[email protected].

Sincerely,
Councilmember Carlos Rodriguez,
Yorba Linda City Council
South Coast AQMD Governing Board Adopts Rail Yards
Indirect Source Rule
It was my pleasure to speak on
behalf of South Coast AQMD at
an event held at Travis Ranch
School in Yorba Linda on October
23rd with Placentia-Yorba Linda
Unified School District (USD) to
showcase its new electric school
buses.

At the event, the school district
leadership team and some
student participants were excited
to ride the bus to feel and hear the
difference. The bus drivers highly
praised the new features of the
electric model and were pleased
on how easily the buses operate.

In 2021, my fellow South Coast
AQMD Board members and
I awarded funding to replace
older diesel, high-emitting,
public school buses with new
alternative fuel or zero-emission
school buses to reduce students’
exposure to cancer-causing
and smog-forming pollution.

Placentia-Yorba Linda USD
received over $2.7 million to
replace seven old diesel school
buses with new zero-emission
electric buses and to install
supporting infrastructure. All
seven zero emission electric
school buses have now been
successfully delivered, and
newly installed charging
stations are fully operational.

This project will provide
emission reductions of
approximately 2.7 tons per
year of smog-forming nitrogen
oxides and 0.2 ton per year of
particulate matter.

The buses will service 15
schools, including Travis Ranch
School, Tynes Elementary, Mabel
Paine Elementary, Rose Drive
Elementary, Wagner Elementary,
Venture Academy, Topaz
Elementary, El Camino School,
Linda Vista Elementary, Morse
Elementary, Kraemer Middle
School, Valencia High School,
Yorba Linda Middle School,
El Dorado High School, and
Woodsboro Elementary.

Greetings!
On August 2nd, my fellow South Coast AQMD
Board members and I adopted Rule 2306,
otherwise known as the Freight Rail Yards
Indirect Source Rule (ISR), which requires rail
yard operators to take actions to meet specific
emission reduction targets.

The rule is expected to reduce nitrogen oxides
(NOx) emissions associated with freight rail
yards by about 10.5 tons per day between
2027 and 2050. The rule will work together
with regulations recently adopted by the
California Air Resources Board (CARB) and
will ensure that rail yards in the South Coast
Air Basin reduce emissions. Freight rail yards
subject to the rule will be required to achieve
up to 82 percent emissions reductions by
2037 through a variety of
actions, including using
cleaner technologies
or lower-emitting
equipment associated
with rail yards.

More than 80 percent
of NOx emissions in the
South Coast Air Basin
come from mobile sources,
with nearly half linked to
goods movement. Cutting NOx is
critical for reducing smog and meeting federal
air quality standards. Communities near rail
yards are especially impacted by ozone and
fine particulate matter from mobile sources.

Emissions tied to rail yards account
for about 9 percent of the region’s
smog-forming emissions. The
Rail Yards ISR covers about 25
facilities located throughout
South Coast AQMD’s
jurisdiction.

The Rail Yards ISR will
become effective after the
U.S. Environmental Protection
Agency approves the Rail Yards
ISR and CARB’s associated rules on
locomotives and drayage truck fleets. For

South Coast AQMD Approves Rule to Accelerate the
Transition to Zero-Emission Building Water Heaters
South Coast AQMD to Receive $500 Million U.S. EPA Grant for ZeroEmission Technologies to Reduce Air Pollution from Goods Movement In June, South Coast AQMD’s Governing Board approved updates to Rule 1146.2 that will require new and existing buildings to transition to zero-emission residential and commercial building water heaters. For the first time ever, natural gas-fired pool heaters, larger water heaters, small commercial water heaters, boilers, and process heaters must meet a zero-emission nitrogen oxides (NOx) standard when replaced.

Combustion sources in residential and commercial buildings are one of many sources of NOx emissions (a precursor to smog) in the region.

Implementing the new amendments to this groundbreaking rule will reduce about 5.6 tons per day of NOx.

The amendments to Rule 1146.2 will impact about one million units across the South Coast AQMD’s four-county jurisdiction. About 710,000 of the impacted units are natural gas-fired residential pool and spa heaters, which have not had NOx limits lowered since the rule’s adoption in 1998. The first compliance deadline under Rule 1146.2 begins on January 1, 2026, following a three-phased schedule, with the final phase concluding by January 1, 2033.

To help offset some of the costs of transition, South Coast AQMD is developing a Zero-Emission Rebate Program that will assist residential and some commercial buildings to transition to zero NOx emission space and water heating, with a focus on overburdened communities.

Future incentives may include other appliances such as cooking or laundry equipment. The program is anticipated to launch by early 2025.

At a press event held on July 22nd, U.S. Senator Alex Padilla, along with the U.S. Environmental Protection Agency (U.S.

EPA), announced a $500 million Climate Pollution Reduction Grant (CPRG) award to South Coast AQMD. The grant was the largest award in the nation and the largest single air-related grant awarded by the U.S. EPA to date.

South Coast AQMD’s CPRG grant titled, INVEST CLEAN is
a transformational initiative aimed at overcoming barriers to transitioning Southern California goods movement to zeroemission (ZE) technologies to reduce greenhouse gas emissions (GHG) and criteria and hazardous air pollutants. INVEST CLEAN will accelerate the adoption of heavy-duty ZE technologies by focusing on building infrastructure to complement the deployment of battery-electric heavy-duty vehicles and equipment to replace older, polluting diesel models.

Transportation accounts for over 50 percent of GHG emissions and nearly 80 percent of the air pollution within the South Coast region. Over the next 25 years, benefits from projects funded under South Coast AQMD’s CPRG grant will create green jobs, foster economic growth, and result in substantial emission reductions.

The U.S. EPA’s CPRG program is a competitive $4.6 billion national grant created under the Inflation Reduction Act. For more information, visit South Coast AQMD’s CPRG program webpage. Page 517 of 1177

SUBJECT: RESOLUTION NO. 2025-5925 APPROVING YORBA LINDA-PLACENTIA

ACTIVE TRANSPORTATION PLAN AND GENERAL PLAN AMENDMENT

TO UPDATE CIRCULATION ELEMENT AND OPEN SPACE AND

RECREATION ELEMENT

RECOMMENDATION
It is recommended that the City Council

1. Approve the Yorba Linda-Placentia Active Transportation Plan.

2. Approve General Plan Amendment to update Circulation Element and Open Space and Recreational Element to implement the Yorba Linda Active Transportation Plan and Update of the Riding, Hiking, and Bikeway Trails component of the General Plan

BACKGROUND
The Yorba Linda-Placentia Active Transportation Plan (ATP) is a collaborative effort between the City of Yorba Linda, the City of Placentia, and the Placentia-Yorba Linda Unified School District to create a community-supported, implementable plan that enhances safety and connectivity within communities in both cities. The plan was made possible by a grant awarded to both cities from the California Department of Transportation (Caltrans).

The plan reflects each city’s unique challenges and opportunities as well as addressing active transportation mobility gaps that negatively impact community access to schools, parks, hospitals, retail centers, and regional and local transit options. Additionally, the plan analyzes existing conditions in both Yorba Linda and Placentia that present communitywide challenges and builds upon previous planning efforts to address them. Public input has been used to better understand the existing and future transportation network needs, and active transportation improvements are recommended to promote healthier and more vibrant communities. In addition to bicycle and pedestrian recommendations in priority areas, the plan also evaluates all public schools in Yorba Linda and Placentia and recommends infrastructure and programming to improve Safe Routes to School.

improvements are prioritized to enable swift implementation to achieve citywide connectivity with pedestrian and bicycle facilities. Additionally, the plan includes an update to the 2005 Yorba Linda’s Riding, Hiking, and Bikeway Trails Component of the General Plan (Master Plan of Trails) to enhance mapping legibility and identify any new recommendations that will help complete the City’s trail network.

On August 28, 2024, this item was brought to the Planning Commission pursuant to Chapter

18.36 of the Zoning Code. As a result of the creation of the ATP and Update to the Master Plan of Trails, the Bicycle and Pedestrians Facilities section of Circulation Element, and Yorba Linda Trails section of Open Space and Recreation Element will need to be amended in the General Plan. During this meeting, the Planning Commission began the first step of the process with the adoption of a resolution initiating the General Plan update.

DISCUSSION
The Draft Yorba Linda-Placentia ATP consists of two major volumes (Attachment 2). Volume 1 is for the ATP which includes Safe Routes to School recommendations, while Volume 2 is for the updated Master Plan of Trails. Any modifications to the ATP need to be accurately reflected within the Yorba Linda General Plan.

The proposed changes in the Bicycle and Pedestrians Facilities section of Circulation Element (Attachment 3) are as follows:
 Add Savi Ranch Parkway from Yorba Linda Boulevard to Mirage and Yorba Linda Boulevard from La Palma Avenue to Savi Ranch Parkway as proposed Class I bikeways. This is a part of the Yorba Linda Boulevard widening project currently in the Capital Improvement Program. Class I bikeways are off-road paths that are separated from vehicular traffic and are for the exclusive use of bicycles and pedestrians.
 Add 40+ street segments for Class II and Class III. Class II (bike lane) is a dedicated lane for bicycle travel separated from a motor vehicle travel lane.

Where feasible, a painted buffer that increases comfort for users would be installed. Class III (bike route/bicycle boulevard) is a bike route that bicyclists share with motor vehicles. It may include pavement markings and traffic calming features such as speed humps and traffic diverters. Class III bikeways are recommended for streets with low vehicle volumes and speeds.  Add the bikeway currently on Fairmont Connector as Class IV. This existing bikeway was constructed as part of the OC Loop project. Class IV bikeways are protected bike lanes that are physically separated from vehicle traffic by vertical barriers such as curbs, bollards, or planters. They are also known as cycle tracks.

The Updated Trails Master Plan (Attachment 4) is a separate, but complementary part of the ATP. This 2024 Plan includes the review of the 2005 Riding, Hiking and Bikeway Trails Component (Master Plan of Trails) Plan, updating it to reflect the current state of trails in the city, including enhancing trail maps and describing the implementation status of previously

recommended trails. Since 2005, many housing developments have been constructed and connections to Yorba Linda’s trails have been completed. This 2024 General Plan update will reflect those trail segments that have since been completed or are in progress.

The 2005 Update was extensive; however, this 2024 General Plan update serves to: 1) identify trail segments that have since been completed or are in progress, 2) fix the readability of the segment maps and 3) make recommendations for future trail connections at a very high-level planning effort. The scope of the Trail Update did not include construction plans or costs associated with any trail recommendations.

There are five (5) new trail recommendations (Segments 51-55) in the 2024 Master Plan of Trails Update found in Attachment 4. Bikeway recommendations in the ATP are also included in the updated Master Plan of Trails. The following trail segments are recommended:

Segment #51:
 Ohio Street is currently a paved road/path
 Requested from outreach with equestrian group and neighbors  Connects to the El Cajon Trail
 Long-term recommendation
This segment would link two trails; the Ohio St. Trail north of Yorba Linda Blvd. and the El Cajon Trail. There is limited right-of-way width along Ohio Street for a paved path or trail, and there is currently a City Council Policy P-6 which states this street is to remain “semirural”, with no sidewalks, curbs, or lighting, thus putting some constraints on building a path in this neighborhood. Due to strong equestrian community support and a couple of adjacent residents, we recommend this path in the Plan, so it may be implemented if constraints are eventually resolved.

Segments #52, 54 and 55:
 Carbon Creek Trail
 Paved path is within boundaries of Yorba Linda, Placentia, and Brea o Recommendation within Yorba Linda boundaries are between Malcolm Lane and Mimosa Drive; and at the crossing of Bastanchury Road Segment #53:
 Earthen path along the south side of Bastanchury Road  Complements existing bike lanes and earthen path on the north side of the road  Connects to existing trails at Emerald Downs Drive and Gun Club Trail Parks and Recreation Commission, Traffic Commission and Planning Commission reviews took place leading up to the City Council Meeting. On October 17, 2024, the Parks and Recreation Commission provided their feedback regarding the update to the Master Plan of Trails component. Then on October 24, 2024, the Traffic Commission provided their input regarding the draft ATP. Due to the fact that the recommended improvements in the ATP

and Master Plan of Trails would result in technical changes to a couple of General Plan mapping exhibits, the Planning Commission then reviewed and recommended approval for the General Plan Amendment 2024-03 on November 13, 2024. Although General Plan amendments are a public hearing matter, no public comments were received regarding the proposed General Plan Amendment 2024-03. The Planning Commission provided a recommendation of approval to the City Council.

FISCAL IMPACT
Capital Projects related to the Active Transportation Plan will be included in future years in the City’s biennial budget process for inclusion in the Seven-Year Capital Improvement Program.

ALTERNATIVES

1. Do not approve the Active Transportation Plan. However, staff does not recommend that as it serves as a roadmap for improving walking, biking and riding conditions and would also allow the city to further pursue state and federal grants to help implement recommended improvements.

2. Other options as directed by the City Council.

Introduction 8 Yorba Linda-Placentia
This Plan analyzes existing conditions in
both Yorba Linda and Placentia that present
community-wide challenges, and it builds
on previous planning efforts to address
these challenges. Public and stakeholder
input is used to understand existing and
future transportation network needs, and
active transportation improvements are
recommended to create healthier and more
vibrant communities. In addition to network
bicycle recommendations, and pedestrian
recommendations in priority areas, this Plan
also evaluates all public schools in Yorba Linda
and Placentia and recommends infrastructure
and programming to improve Safe Routes to
School. Recommended improvements are
prioritized to enable swift implementation to
achieve citywide connectivity with pedestrian
and bicycle facilities.

The Plan allows for modifications and updates
as needed following adoption to address
evolving needs, opportunities, and challenges.

An addendum to the Plan may be incorporated
as warranted to ensure continued relevance
and responsiveness to the communities’
transportation goals.

Purpose of the Plan
The Yorba Linda-Placentia Active
Transportation Plan (Plan) is a collaborative
effort between the City of Yorba Linda, the City
of Placentia, and the Placentia-Yorba Linda
Unified School District to create a communitysupported, implementable plan that will bring safety and connectivity to communities in
Yorba Linda and Placentia. The Plan reflects
the unique challenges and opportunities in
the cities of Yorba Linda and Placentia and
addresses active transportation mobility gaps
that negatively impact access to neighborhood
schools, parks, hospitals, retail centers, and
regional and local transit options.

Active Transportation Plan 9 Introduction
The two cities include integral components
of the greater Orange County active
transportation network, each offering unique
opportunities and challenges for enhancing
connectivity and mobility. Yorba Linda,
characterized by expansive residential
neighborhoods and scenic recreation
destinations, presents an opportunity to
develop safe and accessible walking and
biking paths linking residents to the city’s
expansive trail network, parks, and local
destinations. With its historic downtown
and more compact urban form, Placentia
presents opportunities to prioritize pedestrianfriendly streetscapes and bike infrastructure that cater to residents and visitors alike. By
integrating innovative active transportation
recommendations and community
engagement strategies, this Plan aims to
enhance the quality of life in both cities,
fostering healthier lifestyles and strengthening
community ties through enhanced accessibility
and connectivity.

Study Area
Yorba Linda and Placentia are separate but
neighboring cities in northern Orange County,
CA. The cities are bordered by Brea to the
northwest, Fullerton to the west, Anaheim
to the south, and Chino Hills State Park to
the east and northeast. California State
Route 57 (Orange Freeway) runs along the
western border of both cities and State Route
91 runs along Placentia’s southern border.

Additionally, Imperial Highway (State Route
90) passes through both Yorba Linda and
Placentia at-grade and the two-lane State
Route 142 (Carbon Canyon Road) connects
northern Yorba Linda to Chino Hills in San
Bernardino County. While both cities are
characterized by low- and medium-density
residential communities, Placentia contains
a concentration of industrial and office land
use along its southern end while Yorba Linda
features ample open space.

This Plan includes active transportation
recommendations for both Yorba Linda and
Placentia. These recommendations work to
complement existing and proposed active
transportation facilities in both cities.

The Plan also includes an update to the City
of Yorba Linda’s Master Plan for Riding,
Hiking, and Bikeway Trails (Trails Plan). The
Trails Plan inventories earthen and paved
trails in Yorba Linda that can be used by
pedestrians, bicyclists, and equestrians.

The Trails Plan update recommends
additional trails that complement the active
transportation recommendations in this Plan.

The Trails Plan is included as Volume II of the
Yorba Linda-Placentia Multi-Agency Active
Transportation Plan.
