INTRODUCTION
This noise and vibration impact analysis has been prepared to evaluate the potential noise and vibration impacts and reduction measures associated with the proposed Zest 2.0 Project (project) in Covina, California. This report is intended to satisfy the City of Covina’s (City) requirement for a project-specific noise impact analysis by examining the impacts of the project site and evaluating noise reduction measures that the project may require.
PROJECT LOCATION AND DESCRIPTION
The proposed 2.77-acre project site is located within the central portion of the City of Covina. The project site is located at 747 N. Barranca Avenue (APN 8430-015-021), on the northwest corner of the Barranca Avenue and East Edna Place intersection. Local access is provided by N. Barranca Avenue, E. Cyprus Street, and East Edna Place. The Project site is currently developed with a 3,250 square foot (SF) commercial building, paving, and associated improvements. The project proposes to construct 75 single-family attached residential units within the 2.77-acre site for a density of 27.1 dwelling units per acre. Each residence would include a garage for the unit. The project would also include a driveway entrance from Barranca Avenue, private drives, landscaped areas, and recreational areas. See Figure 1, Project Location, and Figure 2, Site Plan, below.
The project includes approximately 28,776 SF of common open space throughout the site. The open space areas would be landscaped with two main recreation areas. The southwestern portion of the project site would include a tot lot and BBQ area with charcoal grills, seating, and a bocce court. The recreation area in the central portion of the Project site would include an activity lawn and seating.
In addition, each residence would include private open space with either patios or balconies for a total of 11,869 SF of private open space.
The Project site is located within the Town Center Specific Plan and therefore currently has a General Plan land use designation of Town Center Specific Plan (TCSP). The project site currently has a zoning designation of Transit Oriented Development/High-Density Residential (TOD/HDR).
According to the TCSP, the TOD/HDR Zone is a pedestrian-oriented, higher-density residential environment that supports and encourages transit use. Commercial and service uses provide resources to transit riders and to the immediate and neighboring residential areas. Public open spaces are an integral component of large mixed-use or commercial developments. The nonresidential uses provide services for residents that are not available in the Covina Town Center’s historic and commercial cores. Pedestrian connectivity between adjacent land uses is emphasized.
Construction activities would occur over a 13-month period and include the following: (1) demolition of the existing pavement, building, septic system and other infrastructure, and landscaping; (2) grading and excavation; (3) construction of drainage, utilities, and subgrade infrastructure; (4) building construction; and (5) paving and application of architectural coatings. The proposed excavation and grading of the Project site would result in a total import of 2,802 cubic yards of material. Construction activities would be limited to the hours between 7:00 am to 8:00 pm, Monday through Saturday, excluding federal holidays, which would be consistent with the City’s

NOISE AND VIBRATION FUNDAMENTALS
CHARACTERISTICS OF SOUND
Noise is usually defined as unwanted sound. Noise consists of any sound that may produce physiological or psychological damage and/or interfere with communication, work, rest, recreation, and sleep.
To the human ear, sound has two significant characteristics: pitch and loudness. Pitch is generally an annoyance, while loudness can affect the ability to hear. Pitch is the number of complete vibrations, or cycles per second, of a sound wave, which results in the tone’s range from high to low. Loudness is the strength of a sound, and it describes a noisy or quiet environment; it is measured by the amplitude of the sound wave. Loudness is determined by the intensity of the sound waves combined with the reception characteristics of the human ear. Sound intensity is the average rate of sound energy transmitted through a unit area perpendicular to the direction in which the sound waves are traveling. This characteristic of sound can be precisely measured with instruments. The analysis of a project defines the noise environment of the project area in terms of sound intensity and its effect on adjacent sensitive land uses.
MEASUREMENT OF SOUND
Sound intensity is measured with the A-weighted decibel (dBA) scale to correct for the relative frequency response of the human ear. That is, an A-weighted noise level de-emphasizes low and very high frequencies of sound, similar to the human ear’s de-emphasis of these frequencies.
Decibels (dB), unlike the linear scale (e.g., inches or pounds), are measured on a logarithmic scale representing points on a sharply rising curve.
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 sound’s loudness. 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 levels dissipate exponentially with distance from their noise sources.
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. Line-source sound levels decrease 4.5 dB for each doubling of distance in a relatively flat environment with absorptive vegetation.

P:\ESL2201.78\Product\NoiseAndVibrationReport_021424.docx «02/14/24» 9 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 human 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. CNEL is the time-weighted average 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 relaxation hours. CNEL and Ldn are within 1 dBA of each other and are normally interchangeable. The City uses the Ldn noise scale for long-term traffic noise impact assessment.
Other noise rating scales of importance when assessing the annoyance factor include the maximum instantaneous noise level (Lmax), which is the highest 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. It 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, which are 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.
Physiological Effects of Noise
Physical damage to human hearing begins at prolonged exposure to sound levels higher than 85 dBA. Exposure to high sound levels affects the entire system, with prolonged sound exposure in excess of 75 dBA increasing body tensions, thereby affecting blood pressure and functions of the heart and the nervous system. In comparison, extended periods of sound exposure above 90 dBA would result in permanent cell damage. When the sound level reaches 120 dBA, a tickling sensation occurs in the human ear, even with short-term exposure. This level of sound is called the threshold of feeling. As the sound reaches 140 dBA, the tickling sensation is replaced by a feeling of pain in the ear (i.e., the threshold of pain). A sound level of 160–165 dBA will result in dizziness or a loss of equilibrium. The ambient or background noise problem is widespread and generally more

Term Definitions
Decibel, dB A unit of sound measurement that denotes the ratio between two quantities that are proportional to power; the number of decibels is 10 times the logarithm (to the base 10) of this ratio.
Frequency, Hz Of a function periodic in time, the number of times that the quantity repeats itself in 1 second (i.e., the number of cycles per second).
A-Weighted Sound
Level, dBA
The sound level obtained by use of A-weighting. The A-weighting filter de-emphasizes the very low and very high frequency components of the sound in a manner similar to the frequency response of the human ear and correlates well with subjective reactions to noise. (All sound levels in this report are A-weighted unless reported otherwise.)

FUNDAMENTALS OF VIBRATION
Vibration refers to ground-borne noise and perceptible motion. Ground-borne vibration is almost exclusively a concern inside buildings and is rarely perceived as a problem outdoors, where the motion may not be discernible, but without the effects associated with the shaking of a building there is less adverse reaction. Vibration energy propagates from a source through intervening soil and rock layers to the foundations of nearby buildings. The vibration then propagates from the foundation throughout the remainder of the structure. Building vibration may be perceived by occupants as the motion of building surfaces, the rattling of items sitting on shelves or hanging on walls, or a low-frequency rumbling noise. The rumbling noise is caused by the vibration of walls, floors, and ceilings that radiate sound waves. Annoyance from vibration often occurs when the vibration exceeds the threshold of perception by 10 dB or less. This is an order of magnitude below the damage threshold for normal buildings.
Typical sources of ground-borne vibration are construction activities (e.g., blasting, pile-driving, and operating heavy-duty earthmoving equipment), steel-wheeled trains, and occasional traffic on rough roads. Problems with both ground-borne vibration and noise from these sources are usually localized to areas within approximately 100 feet (ft) from the vibration source, although there are examples of ground-borne vibration causing interference out to distances greater than 200 ft .
When roadways are smooth, vibration from traffic, even heavy trucks, is rarely perceptible. It is assumed for most projects that the roadway surface will be smooth enough that ground-borne

Ground-borne noise is not likely to be a problem because noise arriving via the normal airborne path will usually be greater than ground-borne noise.
Ground-borne vibration has the potential to disturb people and damage buildings. Although it is very rare for train-induced ground-borne vibration to cause even cosmetic building damage, it is not uncommon for construction processes such as blasting and pile-driving to cause vibration of sufficient amplitudes to damage nearby buildings. Ground-borne vibration is usually measured in terms of vibration velocity, either the root-mean-square (RMS) velocity or peak particle velocity (PPV). The RMS is best for characterizing human response to building vibration, and PPV is used to characterize the potential for damage. Decibel notation acts to compress the range of numbers required to describe vibration. Vibration velocity level in decibels is defined as:
Lv = 20 log10 [V/Vref]
where “Lv” is the vibration velocity in decibels (VdB), “V” is the RMS velocity amplitude, and “Vref” is the reference velocity amplitude, or 1 x 10-6 inches/second (in/sec) used in the United States.

APPLICABLE VIBRATION STANDARDS
Federal Transit Administration
Vibration standards included in the FTA Manual are used in this analysis for ground-borne vibration impacts on human annoyance. The criteria for environmental impact from ground-borne vibration and noise are based on the maximum levels for a single event. Table E provides the criteria for assessing the potential for interference or annoyance from vibration levels in a building.
Table F lists the potential vibration building damage criteria associated with construction activities, as suggested in the FTA Manual. FTA guidelines show that a vibration level of up to 0.5 in/sec in PPV is considered safe for buildings consisting of reinforced concrete, steel, or timber (no plaster) and would not result in any construction vibration damage. For non-engineered timber and masonry buildings, the construction building vibration damage criterion is 0.2 in/sec in PPV.

OVERVIEW OF THE EXISTING NOISE ENVIRONMENT
The primary existing noise sources in the project area are transportation facilities. Traffic on Barranca Avenue is a steady source of ambient noise.
AMBIENT NOISE MEASUREMENTS
Long-Term Noise Measurements
Long-term (24-hour) noise level measurements were conducted on January 4 and January 8, 2024, using three Larson Davis Spark 706RC Dosimeters. Table G provides a summary of the measured hourly noise levels from the long-term noise level measurements. Hourly noise levels at surrounding sensitive uses are as low as 40.7 dBA Leq during nighttime hours and 53.6 dBA Leq during daytime hours. Long-term noise monitoring data results are provided in Appendix A. Figure 3 shows the longterm monitoring locations.

EXISTING AIRCRAFT NOISE
Airport-related noise levels are primarily associated with aircraft engine noise made while aircraft are taking off, landing, or running their engines while still on the ground. The closest airport to the proposed project site is Brackett Field Airport located approximately 5.1 miles (mi) east of the project site. This is located well outside the limits of potential noise impact.

PROJECT IMPACT ANALYSIS
SHORT-TERM CONSTRUCTION NOISE IMPACTS
Two types of short-term noise impacts could occur during the construction of the proposed project.
First, construction crew commutes and the transport of construction equipment and materials to the site for the proposed project would incrementally increase noise levels on access roads leading to the site. Although there would be a relatively high single-event noise-exposure potential causing intermittent noise nuisance (passing trucks at 50 ft would generate up to 84 dBA Lmax), the effect on longer-term ambient noise levels would be small when compared to existing daily traffic volumes on Barranca Avenue. The results of the California Emissions Estimator Model (CalEEMod) for the proposed project indicate that during the grading phase, an additional 395 vehicles, consisting of worker and hauling trips, would be added to the roadway adjacent to the project site. Because the existing traffic volume on Barranca Avenue is considerably more than 395, construction-related vehicle trips would not approach existing daily traffic volumes and traffic noise would not increase by 3 dBA CNEL. A noise level increase of less than 3 dBA would not be perceptible to the human ear in an outdoor environment. Therefore, short-term, construction-related impacts associated with worker commute and equipment transport to the project site would be less than significant.
The second type of short-term noise impact is related to noise generated during construction, which includes demolition, site preparation, grading, building construction, paving, and architectural coating on the project site. Construction is completed in discrete steps, each of which has its own mix of equipment and, consequently, its own noise characteristics. These various sequential phases would change the character of the noise generated on the site and, therefore, the noise levels surrounding the site as construction progresses. Despite the variety in the type and size of construction equipment, similarities in the dominant noise sources and patterns of operation allow construction-related noise ranges to be categorized by work phase. Table H lists typical construction equipment noise levels recommended for noise impact assessments, based on a distance of 50 ft between the equipment and a noise receptor, taken from the Federal Highway Administration (FHWA) Roadway Construction Noise Model (FHWA 2006).
In addition to the reference maximum noise level, the usage factor provided in Table H is used to calculate the hourly noise level impact for each piece of equipment based on the following equation:
+= − 50 log20.).log(10..)( D quipL FULEe eq
where: Leq (equip) = Leq at a receiver resulting from the operation of a single piece of equipment over a specified time period.
E.L. = noise emission level of the particular piece of equipment at a reference distance of 50 ft.
U.F. = usage factor that accounts for the fraction of time that the equipment is in use over the specified period of time.
D = distance from the receiver to the piece of equipment.

Note: Noise levels reported in this table are rounded to the nearest whole number. 1 Usage factor is the percentage of time during a construction noise operation that a piece of construction equipment is operating at full power. 2 Maximum noise levels were developed based on Specification 721.560 from the Central Artery/ Tunnel program to be consistent with the City of Boston’s Noise Code for the “Big Dig” project.
FHWA = Federal Highway Administration
Lmax = maximum instantaneous sound level
Each piece of construction equipment operates as an individual point source. Using the following equation, a composite noise level can be calculated when multiple sources of noise operate simultaneously:
Using the equations from the methodology above, the reference information in Table H, and the construction equipment list provided, the composite noise level of each construction phase was calculated. The project construction composite noise levels at a distance of 50 feet would range from 74 dBA Leq to 88 dBA Leq, with the highest noise levels occurring during the demolition phase.

P:\ESL2201.78\Product\NoiseAndVibrationReport_021424.docx «02/14/24» 23 Once composite noise levels are calculated, reference noise levels can then be adjusted for distance using the following equation:
In general, this equation shows that doubling the distance would decrease noise levels by 6 dBA, while halving the distance would increase noise levels by 6 dBA.
Table I shows the nearest sensitive uses to the project site, their distance from the center of construction activities, and composite noise levels expected during construction. These noise level projections do not consider intervening topography or barriers. Construction equipment calculations are provided in Appendix B.

Source: Compiled by LSA (2024). 1 The composite construction noise level represents the demolition phase, which is expected to result in the greatest noise level as compared to other phases.
dBA = A-weighted decibels Leq = equivalent continuous sound level While construction noise will vary, it is expected that composite noise levels during construction at the nearest off-site residential uses to the south would reach an average noise level of 78 dBA Leq during daytime hours. These predicted noise levels would only occur when all construction equipment is operating simultaneously and, therefore, are assumed to be rather conservative in nature. While construction-related short-term noise levels have the potential to be higher than existing ambient noise levels in the project area under existing conditions, the noise impacts would no longer occur once project construction is completed.
As stated above, construction activities are regulated by the City’s Noise Ordinance. The proposed project would comply with the construction hours specified in the City’s Noise Ordinance, which states that construction activities are not allowed between the hours of 8 p.m. of any one day and 7 a.m. of the next day, or on Sundays or public holidays. As it relates to off-site uses, constructionrelated noise levels would remain below the daytime 80 dBA Leq 8-hour construction noise level criteria established by the FTA for residential and similar sensitive uses and, therefore, would be considered less than significant. In addition to compliance with the City’s Municipal Code allowed

P:\ESL2201.78\Product\NoiseAndVibrationReport_021424.docx «02/14/24» 24 hours of construction the following recommendations would reduce construction noise to the extent feasible:
• The project construction contractor should equip all construction equipment, fixed or mobile, with properly operating and maintained noise mufflers, consistent with manufacturer’s standards.
• The project construction contractor should locate staging areas away from off-site sensitive uses during the later phases of project development.
• The project construction contractor should place all stationary construction equipment so that emitted noise is directed away from sensitive receptors nearest the project site whenever feasible.
SHORT-TERM CONSTRUCTION VIBRATION IMPACTS
This construction vibration impact analysis discusses the level of human annoyance using vibration levels in VdB and assesses the potential for building damages using vibration levels in PPV (in/sec).
This is because vibration levels calculated in RMS are best for characterizing human response to building vibration, while calculating vibration levels in PPV is best for characterizing the potential for damage.
Table J shows the PPV and VdB values at 25 ft from the construction vibration source. As shown in Table J, bulldozers and other heavy-tracked construction equipment (expected to be used for this project) generate approximately 0.089 PPV in/sec or 87 VdB of ground-borne vibration when measured at 25 ft, based on the FTA Manual. The distance to the nearest buildings for vibration impact analysis is measured between the nearest off-site buildings and the project construction boundary (assuming the construction equipment would be used at or near the project setback line).
The formulae for vibration transmission are provided below, and Tables K and L provide a summary of off-site construction vibration levels.
LvdB (D) = LvdB (25 ft) – 30 Log (D/25)
PPVequip = PPVref x (25/D)1.5
As shown in Table E, above, the threshold at which vibration levels would result in annoyance would be 78 VdB for daytime residential uses. As shown in Table F, the FTA guidelines indicate that for a non-engineered timber and masonry building, the construction vibration damage criterion is
0.2 in/sec in PPV.

PPV = peak particle velocity
Based on the information provided in Table K, vibration levels are expected to approach 64 VdB at the closest residential uses located immediately south of the project site, which is below the 78 VdB threshold for annoyance.
Based on the information provided in Table L and heavy equipment operations presented in the project description, it is expected that construction activities utilizing heavy equipment would generate vibration levels approaching 0.174 which is less than 0.2 in/sec in PPV when operating within 10 ft of the property line or a distance of 16 feet from the nearest surrounding structures.
Vibration levels at all other buildings would be lower. Although construction vibration levels at the nearest buildings would have the potential to result in annoyance, these vibration levels would no longer occur once construction of the project is completed. Therefore, construction would not result in any vibration damage, and impacts would be less than significant.
Because construction activities are regulated by the City’s Municipal Code, which states that temporary construction, maintenance, or demolition activities are not allowed between the hours of 8 p.m. of any one day and 7 a.m. of the next day, or on Sundays or public holidays, vibration impacts would not occur during the more sensitive nighttime hours.
LONG-TERM OFF-SITE TRAFFIC NOISE IMPACTS
In order to assess the potential traffic impacts related to the proposed project, a Trip Generation and Vehicle Miles Traveled (VMT) Screening Analysis (EPD Solutions, Inc. 2023) has been prepared.
Based on the analysis results, it was determined that a net additional 533 average daily trips (ADT) would be generated by the proposed project. The existing (2019) traffic volume on the adjacent segment of Barranca Avenue is 21,732 (MIG, 2019). The following equation was used to determine the potential impacts of the project:

where: Vexisting = existing daily volumes
Ve+p = existing daily volumes plus project
Change in CNEL = increase in noise level due to the project The results of the calculations show that an increase of approximately 0.1 dBA Ldn is expected along the street adjacent to the project site. A noise level increase of less than 1 dBA would not be perceptible to the human ear; therefore, the traffic noise increase in the vicinity of the project site resulting from the proposed project would be less than significant. No mitigation is required.
LONG-TERM TRAFFIC-RELATED VIBRATION IMPACTS
The proposed project would not generate vibration levels related to on-site operations. In addition, vibration levels generated from project-related traffic on the adjacent roadways are unusual for onroad vehicles because the rubber tires and suspension systems of on-road vehicles provide vibration isolation. Based on a reference vibration level of 0.076 in/sec PPV, structures greater than 20 ft from the roadways that contain project trips would experience vibration levels below the most conservative standard of 0.12 in/sec PPV; therefore, vibration levels generated from project-related traffic on the adjacent roadways would be less than significant, and no mitigation measures are required.

LAND USE COMPATIBILITY
The dominant source of noise in the project vicinity is traffic noise from roadways in the vicinity of the project.
EXTERIOR NOISE ASSESSMENT
Based on the monitoring results shown in Table G and adjusting for distance, existing traffic noise levels at the project site are expected to approach 77 dBA Ldn at the building setbacks closest to Barranca Avenue. The southwestern portion of the Project site would include a tot lot and BBQ area with charcoal grills, seating, and a bocce court. The recreation area in the central portion of the Project site would include an activity lawn and seating. The proposed central recreation area is located approximately 250 ft away from the Barranca Avenue centerline. After distance attenuation and shielding from the proposed buildings, the noise levels at the amenities would be reduced below the normally acceptable level of 60 dBA Ldn. Additionally, the BBQ area is located farther and would be shielded by the proposed buildings. Therefore, noise levels at outdoor noise-sensitive uses would not exceed the City’s exterior allowable noise exposure level of 60 dBA Ldn.
INTERIOR NOISE ASSESSMENT
As discussed above, per the City’s Municipal Code, an interior noise level standard of 45 dBA Ldn or less is required for all noise-sensitive rooms. Based on the expected future exterior noise levels at the buildings closest to Barranca Avenue approaching 77 dBA Ldn, a minimum noise reduction of 32 dBA would be required.
Based on reference information from transmission loss test reports for various Milgard windows (Milgard 2008), the necessary reduction can be achieved with standard building construction and upgraded windows with Sound Transmission Class (STC) ratings of 30–35, depending on the window-to-glass ratio, at Building 1 and east of Building 6, which would not be shielded by a noise barrier. For all other buildings, which are farther from Barranca Avenue and would be shielded by the proposed buildings, with standard building construction along with standard windows (typically in the STC 25–28 range), interior noise levels of 45 dBA Ldn or less would be achieved.
Once final plans are available to detail the exterior wall construction and a window manufacturer has been chosen, a Final Acoustical Report would be required to confirm the reduction capability of the exterior façades and to identify any specific upgrades necessary to achieve an interior noise level of 45 dBA Ldn or below.

Site: Covina Recreational Center
Subject: Level of Service Screening Analysis
This technical memorandum evaluates the trip generation and need to prepare a level of service (LOS) analysis for the proposed recreational center located at 747 N Barranca Avenue in the City of Covina. The Project proposes to construct 75 Townhomes (“Project”). The Project would construct 75 townhome units on the 2.77-acre site for a density of 27.1 dwelling units per acre. Each townhome would include a 2-car garage for the unit, the Project would provide parking at a rate of 2.3 spaces per home with 128 garage spaces, 25 guest spaces, and 18 driveway spaces for a total of 171 parking spaces. Access to the Project would be provided by a full access driveway entrance from Barranca Avenue. The Project site plan is shown in Figure 1.
Project Trip Generation and TIA Screening
The Project trip generation was prepared using trip rates from the Institute of Transportation Engineers (ITE)1.for Single Family Attached Housing (Land Use Code 215) Table 1 presents the trip generation estimate for the proposed project. As shown in Table 1, the project is forecast to generate 540 daily trips including 36 trips during the AM peak hour and 43 trips during the PM peak hour.
LOS Screening Analysis
As detailed in the ‘Introduction’ Section (page 8) of the City’s TIA Guidelines for Vehicles Miles Traveled and Level of Service Assessment, a TIA that includes an LOS analysis is not required for projects that generate less than 50 vehicle trips during either the AM or PM peak hour. As shown in Table 1, the project is forecast to generate 36 AM peak hour trips and 43 PM peak hour trips. Therefore, the proposed project would not generate 50 or more vehicle trips during the peak hour, and a TIA that includes an LOS analysis is not required.
Summary
As shown in Table 1, the Project is forecast to generate 540 daily trips including 36 trips during the AM peak hour and 43 trips during the PM peak hour.
Using the LOS Guidelines, the Project would generate significant impacts. Thus, a TIA LOS analysis would not be required for the Project.

Subject: Trip Generation and Vehicle Miles Traveled (VMT) Screening Analysis This technical memorandum evaluates the trip generation and need to prepare a vehicle-miles traveled (VMT) analysis for the proposed Zest 2.0 residential Project located at 747 N Barranca Avenue in the City of Covina. The Project proposes to construct 75 townhomes (“Project”). The Project would construct 75 townhome units on the 2.77-acre site for a density of 27.1 dwelling units per acre. All of the homes are designed with a minimum 1-car garage for smaller 1-bedroom units and 2-car garage for the larger onebedroom and multi-bedroom units, the Project would provide parking at a rate of 2.3 spaces per home with 128 garage spaces, 25 guest spaces, and 18 driveway spaces for a total of 171 parking spaces. Access to the Project would be provided by a full access driveway entrance from Barranca Avenue. The Project site plan is shown in Figure 1.
Project Trip Generation and TIA Screening
The Project trip generation was prepared using trip rates from the Institute of Transportation Engineers (ITE)1 for Single Family Attached Housing (Land Use Code 215). Table 1 presents the trip generation estimate for the proposed Project. As shown in Table 1, the project is forecast to generate 540 daily trips including 36 trips during the AM peak hour and 43 trips during the PM peak hour.
VMT Screening Analysis
Senate Bill (SB) 743 was signed by Governor Brown in 2013 and required the Governor’s Office of Planning and Research (OPR) to amend the CEQA Guidelines to provide an alternative to LOS for evaluating Transportation impacts. SB743 specified that the new criteria should promote the reduction of greenhouse gas emissions, the development of multimodal transportation networks and a diversity of land uses. The bill also specified that delay-based level of service could no longer be considered an indicator of a significant impact on the environment. In response, Section 15064.3 was added to the CEQA Guidelines beginning January 1, 2019. Section 15064.3 - Determining the Significance of Transportation Impacts states that Vehicle Miles Traveled (VMT) is the most appropriate measure of transportation impacts and provides lead agencies with the discretion to choose the most appropriate methodology and thresholds for evaluating VMT.
Section 15064.3(c) states that the provisions of the section shall apply statewide beginning on July 1, 2020.
The City of Covina adopted VMT guidelines referenced in the Transportation Study Guidelines for Vehicle Miles Traveled and Level of Service Assessment (VMT Guidelines October 2020). The VMT Guidelines identify screening thresholds to determine if projects would require a full VMT analysis. If a project meets one of the following criteria, then the VMT impact of the project is considered less-than significant and no further analysis of VMT would be required:
1. The project is located within a Transit Priority Area (TPA).
2. The project is located in a low VMT generating area.
3. The project is locally serving or generates less than 110 daily vehicle trips. 1 Trip Generation, 11th Edition, Institute of Transportation Engineers (ITE). 2021.

VMT Screening Analysis

The applicability of each criterion to the proposed Project is discussed below.
Screening Criteria 1 - Transit Priority Area Screening: The project is located in a TPA, as shown in Figure 2; however, to qualify for the Transit Priority Area Screening, the Project must also not meet the following criteria:
1. Has a Floor Area Ratio (FAR) of less than 0.75: the Project has an FAR of approximately 0.94, which is above the 0.75 threshold.
2. Provide more parking for use by residents of the project than required by the City: All of the townhomes are designed with a minimum 1-car garage for smaller one-bedroom units and 2-car garage for the larger one-bedroom and multi-bedroom units, within the minimum requirement set by the City of Covina for townhomes.
3. Is inconsistent with the applicable Sustainable Communities Strategy (as determined by the lead agency, with input from the Southern California Association of Governments [SCAG]): The Sustainable Communities Strategy uses growth assumptions based on the City’s General Plan land use designations. The Project site’s land use designation is consistent with the proposed development; therefore, the Project would be consistent with the Sustainable Communities Strategy.
4. Replace affordable residential units with a smaller number of moderate- or high-income residential units: The Project location does not have affordable housing located on site; therefore, the Project would not replace any affordable residential units.
As the Project is within a TPA and does not meet any of the criteria set in the City VMT Guidelines, the Project would meet Screening Criteria 1.
Screening Criteria 2 - Low VMT Area Screening: According to the City’s guidelines, residential and office projects may be presumed to have a less than significant impact absent substantial evidence to the contrary.
The SGVCOG (San Gabriel Valley Council of Governments ) VMT Evaluation Tool was used to determine if the proposed Project lies in a low VMT area. The Project’s site is not located in a VMT area lower than the City average as shown in Appendix A. Therefore, the Project would not meet Screening Criteria 2.
Screening Criteria 3 – Local Serving Land Use or Trip Generation Screening: According to the City’s guidelines, projects that serve the local community or generate less than 110 daily vehicle trips and have the potential to reduce VMT would not be required to complete a VMT assessment. These types of projects include K-12 schools, local serving retail, day care centers, student housing and other community institutions.
The Project proposes 75 townhome units, which is not considered a locally serving use, and is expected to generate over 110 daily trips. Therefore, the Project would not meet Screening Criteria 3.
Summary
As shown in Table 1, the Project is forecast to generate 540 daily trips including 36 trips during the AM peak hour and 43 trips during the PM peak hour.
Using the City’s VMT Guidelines, while the Project would not satisfy Screening Criteria 2 and 3; however, the Project would satisfy Criteria 1. Therefore, the proposed Project would screen out of further VMT analysis and have a less than significant VMT impact.

SECTION 3. After giving full consideration to all evidence presented at the public hearing, both oral and written, and after being fully informed, the City Council does hereby find and decide, with regards to Vesting Tentative Tract Map (VTTM) 84311 and pursuant to Covina Municipal Code (CMC) Section 16.08.140 finds that:
1. The proposed subdivision is consistent with the General Plan as follows:
Facts: The Vesting Tentative Tract Map (VTTM) proposes the development of residential lots, parkways, on-street parking, private drives, curb, gutter, sidewalk and storm drain improvements, wet and dry utilities, and related infrastructure improvements. The residential component of the development Project encompasses the residential development of seventy-five (75) “for-sale” condominium townhouse units (2.77 acres).
The residential units will provide between one to three-bedroom units. On-site amenities for the residences include open space areas and paseos, an outdoor grilling area with multiple grills and a food preparation area, picnic tables, an overhead shade structure, a Bocce Ball Court, and a butterfly garden. The Project is consistent with the General Plan, Covina Town Center Specific Plan (CTCSP), and all applicable codes and regulations. The CTCSP allows a more flexible application of development standards while maintaining compatibility with existing surrounding uses and consistency with the General Plan. The proposed Project has been designed to be consistent with the CTCSP zoning designation of Transit Oriented Development/High Density Residential (TOD/HDR). The TOD/HDR designation allows for 26-40 du/acre residential densities for stand-alone residential parcels larger than 0.51 acre. The Project proposes stand-alone residential on the 2.77-acre site for a density of 27.1 du/acre, which is within the designation's limit. (Land Use Element Policy
2.6) Within the CTCSP, the purpose of the TOD/HDR zone is to provide a pedestrianoriented, higher-density residential environment that supports and encourages transit use.
The proposed Project is located 0.27 miles from the existing Metrolink Covina Station. It will provide pedestrian access to the station via a pedestrian connection through the adjacent multi-family residential development (Zest 1.0) and recreation facilities (Kelby Park and future Covina Recreation Village Park). (Land Use Element Policy 1.22 and
Resolution CC 2024-45 Page 4 of 11
2.17). Therefore, this criterion has been met.
2. The design and improvements of the proposed subdivision are consistent with the General Plan.
Facts: The Project Site has a General Plan designation of Covina Town Center Specific Plan (CTCSP) and is zoned Transit Oriented Development/High-Density Residential (TOD/HDR). The CTCSP adopted density ranges that reflect existing and desired scales of development in the community, allow for moderate future growth, address the intent of regional housing obligations, and will not inhibit the City’s ability to meet street capacities and to provide other infrastructure, utilities, and adequate community services (Land Use Element Policy 2.17). The Project also captures potential benefits from the Metrolink Commuter Train Station, downtown revitalization, and other major programs/efforts (Land Use Element Policy 1.22). The Project proposes stand-alone residential on the 2.77-acre site for a density of 27.1 du/acre, which is within the designation's limit. Within the CTCSP, the purpose of the TOD/HDR zone is to provide a pedestrian-oriented, higher-density residential environment that supports and encourages transit use. The proposed Project is located 0.27 miles from the existing Metrolink Covina Station. It will provide pedestrian access to the station via a pedestrian connection through the adjacent multi-family residential development (Zest 1.0) and future recreation facilities (Kelby Park and future Covina Recreation Village Park).
3. The tentative map proposes to divide land which is subject to a contract entered into pursuant to the California Land Conservation Act of 1965, or the land is subject to a Land Conservation Act contract and the resulting parcels following division of the land will be too small to sustain their agricultural use.
Facts: The Project Site is within the CTCSP, with a zoning designation of Transit Oriented Development/High-Density Residential (TOD/HDR, which does not permit agricultural uses, and no agricultural uses currently exist on-site. In addition, the Project Site is not part of a Williamson Act contract or any other sort of deed or land use restriction intended to preserve or foster agricultural uses. Therefore, the Project would not conflict with existing zoning for agricultural use or a Williamson Act contract, an no impact would occur.
4. The subdivision is physically suitable for the type and proposed density of development proposed by the tentative map.
Facts: The proposed Project has been designed to be consistent with the CTCSP zoning designation of Transit Oriented Development/High-Density Residential (TOD/HDR). The TOD/HDR designation allows for 26-40 du/acre residential densities for stand-alone residential parcels larger than 0.51 acre. The Project proposes stand-alone residential on the 2.77-acre site for a density of 27.1 du/acre, which is within the designation's limit. The proposed Vesting Tentative Tract Map encompasses the residential development of 75 residential units, which will create one horizontal residential lot with associated site improvements consisting of parkways, on-street parking, private drives, curb, gutter, sidewalk, and storm drain improvements, wet and dry utilities, and related infrastructure improvements. Access to the site will be provided via a driveway along Barranca Avenue.
Onsite Private Drives “A” through “D” will provide residents and guests access to guest spaces and garages. Infrastructure improvements will include an onsite water system
Resolution CC 2024-45 Page 5 of 11
comprised of 6-inch water lines that would connect to the existing 10-inch water main in Barranca Avenue. An onsite sewer system comprises 8-inch gravity sewer lines that will connect to the existing 8-inch sewer line southwest of the Project site on Red Ruby Drive.
Stormwater will be conveyed as surface flow to the Project’s backbone storm drain system, conveyed westerly and then southerly to the southwesterly corner of the Project site. The Project would include installing onsite storm drain lines that connect onsite flows to the existing City storm drain line to the southwest of the Project site in Red Ruby Drive. The Project would also include a subsurface infiltration facility in the site's southwestern corner. The subsurface infiltration facility would include pre-treatment of stormwater using a Storm-trap vault. Therefore, this criterion has been met.
5. The design of the subdivision and proposed improvements, with conditions of approval, will not be likely to cause significant environmental damage or substantially and avoidably injure fish or wildlife or their habitat.
Facts: The Project site is approximately 2.77 acres in size, in a predominantly urban location, and is surrounded by existing single-family homes to the west, Kelby Park to the north, residential and commercial uses to the south, and commercial and industrial uses to the east. The Project site is currently used for equipment storage in a vacant commercial building. The site is not a designated fish or wildlife habitat or located nearby to any such territory. Therefore, the subdivision will not likely cause significant environmental damage or substantially and avoidably injure fish or wildlife or their habitat. Therefore, this criterion has been met.
6. The design of the subdivision and the type of improvements are not likely to cause serious public health problems.
Facts: As previously described within the “Project Analysis” portion of the staff report and summarized in Tables 2 and 3, the proposed Project has been designed to be consistent with the CTCSP zoning designation of Transit Oriented Development/High-Density Residential (TOD/HDR). The TOD/HDR designation allows for 26-40 du/acre residential densities for stand-alone residential parcels larger than 0.51 acre. The Project proposes stand-alone residential on the 2.77-acre site for a density of 27.1 du/acre, which is within the designation's limit. Within the CTCSP, the purpose of the TOD/HDR zone is to provide a pedestrian-oriented, higher-density residential environment that supports and encourages transit use. The proposed Project is located 0.27 miles from the existing Metrolink Covina Station. It will provide pedestrian access to the station via a pedestrian connection through the adjacent multi-family residential development (Zest 1.0) and recreation facilities (Kelby Park and future Covina Recreation Village Park. The design of the Project will provide 28,776 SF of common open space throughout the site, including an outdoor grilling area with multiple grills and a food preparation area, picnic tables, an overhead shade structure, a Bocce Ball Court, and a butterfly garden. The overall subdivision design, the proposed uses, the types of improvements, and the Conditions of Approval will ensure the development is in harmony with surrounding land uses and will not cause serious public health problems. Therefore, this criterion has been met.
7. The design of the subdivision provides for future passive or natural heating and cooling opportunities in the subdivision to the extent feasible.
Resolution CC 2024-45 Page 6 of 11
Facts: The design of the subdivision provides for both passive and natural heating and cooling opportunities. The residential development with 75 “for-sale” condominium townhouse units will have operable windows for passive and natural heating. The residential development will require compliance with Title 24 of the Uniform Building Code. Therefore, this criterion has been met.
8. The design of the subdivision and the type of improvements will conflict with easements acquired by the public at large for access through or use of property within the proposed subdivision, or the design of the alternate easements which are substantially equivalent to those previously acquired by the public will not be provided.
Facts: The Project will include constructing an onsite water system comprised of 4-inch and 6-inch water lines connecting to the existing 10-inch water main in Barranca Avenue.
The Project will also include constructing 8-inch private fire systems that supply water to four proposed fire hydrants and the onsite sprinkler system. The proposed 8-inch fire water lines will connect to the existing 10-inch water main in Barranca Avenue and an 8-inch water line in the easement along the site's southern boundary. The Project will also include constructing an onsite sewer system comprised of 6-inch and 8-inch gravity sewer lines that connect to the existing 8-inch sewer line in N. Citrus Avenue and the 15-inch sewer line in N. Barranca Avenue. Drainage improvements will involve stormwater being conveyed as surface flow to the Project’s backbone storm drain system and conveyed westerly and then southerly to the southwestern corner of the Project site. The Project will include approximately 400 feet of new storm drain lines connecting onsite flows to the existing City storm drain line. The Project will also include two subsurface infiltration basins located in the center of the site. The subsurface infiltration basins will include pretreatment of stormwater using bio-filtration units. The proposed stormwater system will specifically serve the residential development site and the future Covina Recreation Village site (“Leg Portion”). Therefore, the future maintenance of the system will be the responsibility of both the property owners within the proposed residential project and the City of Covina (for the future Covina Recreation Village portion). Future maintenance activities would include ongoing routine maintenance of the system and future replacement/repair of portions of the system as necessary. As a condition of approval, the Property (Zest 2.0) shall generate, through their Homeowners Association, funds to pay for a pro-rata share of ongoing maintenance, as well as future repair/replacement of Stormwater Infiltration and Conveyance System infrastructure through the creation of an Assessment District to be applied to the future property owners. Lastly, a formal annexation vote was sent to the HOA for their approval, with a deadline to submit all ballots by May 22, 2024. To incorporate the property (Zest-2) within the community (Zest-1), 67% of the community owners must approve the annexation of Zest-2. This annexation will include pedestrian connections, shared access between residential developments to the future Recreation Village and Kelby Park facilities, additional guest parking, common area amenities, and infrastructure connections, resulting in one unified development. With an approved annexation, there will be no conflict with easements acquired by the public at large for access through or the use of the subdivision or with the design of alternate easements that are substantially equivalent to those previously acquired by the public. In the event the Community (Zest-1) does not approve the annexation, the development of
Resolution CC 2024-45 Page 7 of 11
Zest-2 will continue and be developed as a separate project with a separate HOA. The Zest2 Project will not share any on-site amenities or parking or provide pedestrian access between each site, and Zest-1 will continue to operate with no changes. Therefore, this criterion has been met.
9. The Project's subdivision design is consistent with the city’s parkland dedication requirements (Quimby Act—Chapter 16.28 CMC).
Facts: The Project is subject to Parkland Impact Fee to the City, pursuant to the City’s Quimby Act Ordinance (CMC Chapter 16.28). Therefore, this criterion has been met.
10. The Applicant has demonstrated that a sufficient water supply will be available to serve the subdivision in accordance with California Government Code Section 66473.7.
Facts: The Project will include constructing an onsite water system comprised of 6-inch water lines that will connect to the existing 10-inch water main in Barranca Avenue. The onsite water system would be compliant with the California Plumbing Code (Title 24) for efficient use of water. The Project is required to comply with Covina Municipal Code Chapter 17.82 regarding Water Efficient Landscape Regulations and the State July 2015 Model Water Efficient Landscape Ordinance (MWELO) as amended. The Project will include several exterior water conservation measures, including but not limited to the following: Smart Irrigation Controllers, Central Computer Irrigation Controllers for Common Areas, Soil Moisture Sensor Systems, Large Rotary Nozzles, bubblers, microsprays, and drip irrigation. Interior water conservation strategies will include low-flow fixtures (faucets) and appliances (tank toilets and clothes washers). According to the City’s Public Works Department, the City has sufficient capacity to provide water to serve the subdivision without negative impact on other properties in the City, based on Covina’s 2015 Urban Water Management Plan. Therefore, this criterion has been met.
SECTION 4. After giving full consideration to all evidence presented at the public hearing, both oral and written, and after being fully informed, the City Council does hereby find and decide, with regards to Site Plan Review (SPR) 23-253 and pursuant to Title 17.64.070 of the Covina Municipal Code, that:
1. All provisions of Title 17 of the Covina Municipal Code are complied with.
Facts: As previously described within the “Project Analysis” portion of the staff report, the proposed Project has been designed to be consistent with the CTCSP zoning designation of Transit Oriented Development/High-Density Residential (TOD/HDR). The redevelopment of an existing commercial site to allow the construction of a 75-unit, threestory, Multi-Family Residential Condominium Townhome Development will increase the number of housing units and residents in the area, stimulating development on vacant infill and under-utilized properties, allow for moderate future growth, address regional housing obligations, and will not inhibit the City’s ability to meet street capacities and to provide other infrastructure, utilities, and adequate community services (Land Use Element Policy
2.17). Therefore, this criterion has been met.
2. The design and layout of the proposed development are consistent with the general
Resolution CC 2024-45 Page 8 of 11
plan, zoning code, development standards of the applicable zoning district, specific plans, design guidelines and objective design standards; Facts: The Project site is located within the Town Center Specific Plan and a General Plan land use designation of Town Center Specific Plan (TCSP). The Project site currently has a zoning designation of Transit Oriented Development/High-Density Residential (TOD/HDR). According to the TCSP, the TOD/HDR Zone is a pedestrian-oriented, higherdensity residential environment that supports and encourages transit use. Commercial and service uses provide resources to transit riders and to the immediate and neighboring residential areas. Public open spaces are an integral component of large mixed-use or commercial developments. The nonresidential uses provide services for residents that are not available in the Covina Town Center’s historic and commercial cores. Pedestrian connectivity between adjacent land uses is emphasized. The proposed Project is located
0.27 miles from the existing Metrolink Covina Station. It will provide pedestrian access to the station via a pedestrian connection through the adjacent multi-family residential development (Zest 1.0) and recreation facilities (Kelby Park and future Covina Recreation Village Park). Access to the site would be provided via a driveway along Barranca Avenue.
Onsite Private Drives “A” through “D” will provide residents and guests access to guest spaces and garages.
3. The design of the proposed development or the alterations to existing structures will not interfere with the use and enjoyment of existing neighborhood and future development, and will not create traffic or pedestrian hazards; Facts: The Project is situated within the CTCSP zoning designation of Transit Oriented Development/High-Density Residential (TOD/HDR), oriented within a designated medium- and high-density use zone, such as apartments, condominiums, townhomes, and mobile home parks, in and/or around the downtown and in areas where such developments now can exist (Land Use Element Policy 2.6). The Project also captures potential benefits from the Metrolink Commuter Train Station, downtown revitalization, and other major programs/efforts (Land Use Element Policy 1.22). Within the CTCSP, the purpose of the TOD/HDR zone is to provide a pedestrian-oriented, higher-density residential environment that supports and encourages transit use. The proposed Project is located 0.27 miles from the existing Metrolink Covina Station. The Project will provide pedestrian access to the station via a pedestrian connection through the adjacent multi-family residential development (Zest 1.0) and recreation facilities (Kelby Park and future Covina Recreation Village Park). Access to the site would be provided via a driveway along Barranca Avenue.
Onsite Private Drives “A” through “D” will provide residents and guests access to guest spaces and garages.
4. The proposed development has been reviewed in compliance with the provisions of the California Environmental Quality Act (CEQA);
Facts: A memorandum was prepared analyzing the proposed Project to determine its eligibility to be exempt from further CEQA review based on its infill characteristics and pursuant to its consistency with the adopted Specific Plan and certified Environmental Impact Report (EIR). Development. Development Projects that are undertaken pursuant to a specific plan for which an EIR was previously paired are exempt from further CEQA review if the projects are in conformity with that specific plan and the conditions described
Resolution CC 2024-45 Page 9 of 11
in CEQA Guidelines section 15162 are not present. Based on the proposed Project description, knowledge of the Project site, and findings of the CTCSP EIR, the City has concluded that the proposed Project would not result in any new or increased impacts not previously disclosed in the CTCSP EIR. For these reasons, the staff has concluded that the Project qualifies for a Class 32 Exemption because it is (1) consistent with the General Plan designation and polices and zoning regulations, (2) is located within the City limits, surrounded by urban uses and is less than 5 acres in size; (3) has no value for endangered, rare or threatened specifies; (4) would not result in any significant effects related to traffic, noise, air quality or water quality; and (5) can be adequately served by all required utilities and public services.
5. The proposed development will not be detrimental to the public health, safety or welfare or materially injurious to the properties or improvements in the vicinity; Facts: Construction activities during the design of the subdivision and the type of improvements are not likely to cause serious public health problems. All potentially hazardous materials used during project construction will be disposed of in accordance with manufacturers’ specifications and instructions, thereby reducing the risk of hazardous materials use. In addition, the Project would comply with all applicable federal, state, and local requirements concerning the use, storage, and management of hazardous materials, including but not limited to the Resource Conservation and Recovery Act, California Hazardous Waste Control Law, federal and state Occupational Safety and Health Acts, SCAQMD rules, and permits and associated conditions issued by the Building and Safety Division.
6. The development complies with the provisions for dedications, public improvements and undergrounding utilities pursuant to CMC 17.64.140 and congestion management and transportation demand management requirements pursuant to CMC 17.64.150.
Facts: The Project would include construction of an onsite water system comprised of 6- inch water lines that would connect to the existing 10-inch water main in Barranca Avenue.
The Project would include construction of an onsite sewer system comprised of 8-inch gravity sewer lines that would connect to the existing 8-inch sewer line southwest of the Project site in Red Ruby Drive. In the proposed condition, stormwater would be conveyed as surface flow to the Project’s backbone storm drain system and conveyed westerly and then southerly to the southwestern corner of the Project site. The Project would include installation of onsite storm drain lines that would connect onsite flows to the existing City storm drain line to the southwest of the Project site in Red Ruby Drive. The Project would also include a subsurface infiltration facility located in the southwestern corner of the site.
The subsurface infiltration facility would include pre-treatment of stormwater via the use of a Storm-trap vault. All new utility service lines that are installed to serve the new building development shall be placed underground. Utility service lines include service for electricity, telephone communications, and cable television. The Applicant shall make all necessary arrangements with the serving utility company to provide underground services.

C. VESTING TENTATIVE TRACT MAP (VTTM) 83178
1. The Project shall annex into Community Facilities District 2007-01 (the "CFD") for the purpose of financing the Project's proportionate share of the cost for police response, fire and emergency medical response, and park services. The Applicant shall petition the City to annex to the City’s existing CFD under the California Mello-Roos Community Facilities Act (Government Code, Section 53311 et seq.) (the Act"). The annexation process places a special tax on the property owner’s tax bill. In FY23-24 the tax is as follows:
Tax Class Description Maximum Special Tax
1 Single-Family Residential $832.13 per unit
2 Multi-Family Residential $623.70 per unit
3 Mixed-Use Property $623.70 per unit
CFD calculation of annual cost for FY2023-2024:
Land Use Tax 2020-2021 No. of Units Annual Tax
Single-Family Residential $832.13 X =
Multi-Family Residential $623.70 X 75 = $46,777.50
Note: This amount may be adjusted annually by the Annual Escalator factor, which is the greater of two percent (2%) or the percent change in the Consumer Price Index for the calendar year ending in December of the prior fiscal year.
CITY OF COVINA
CONDITIONS OF APPROVAL

12923-0001\2973529v2.doc
The annexation process takes approximately two months and includes two City Council meetings, one of which is a public hearing and a special election. The annexation shall be completed prior to issuance of building permits for any units. The applicant is responsible for the cost incurred by the City to annex the development to the CFD. The cost of the annexation process is approximately $3,500.
Alternatively, at the Applicant's option, in lieu of annexation to the CFD as set forth above, Applicant may make a lump sum payment to the City (“In Lieu Payment") representing the Project's proportionate share of the cost for police response, fire and emergency medical response, and park services. In Lieu Payment shall be calculated based upon the net present value of the special tax that would be levied upon the Project under the CFD over the term of the CFD special tax. If the applicant wishes to make an In-Lieu Payment, the applicant will be required to provide a deposit to the City to fund the cost for calculating the In-Lieu Payment.
The In Lieu Payment must be paid not later than prior to release of occupancy for the first lot/dwelling unit, including the model homes, within the Project.
