STAFF REPORT
7/10/2024
TO: Honorable Mayor and City Council Members
FROM: Gabriel Perez, Development Services Director
SUBJECT: Coachella Valley Event Center
SPECIFICS: Adopt Resolution No. 2024-37 approving Entertainment Permit No. 22-04 for the Coachella Valley Event Center, an entertainment venue located on a 20-acre site at 46600 Tyler Street (APN# 603-130-001). Applicant: Edwart Rostamian STAFF RECOMMENDATION:

Staff recommends Council adopt Resolution No. PC 2024-37 approving Entertainment Permit No. 22-04, pursuant to the findings and conditions of approval contained in the attached resolution.

BACKGROUND:

The subject site is a 20-acre property 46600 Tyler Street located on a site that was formerly operated as the Corona Yacht Club, which includes on-site improvements that include an existing single-family residence, large covered structures for the event center, restrooms, lake, and an elevated walking path all located towards the northeast portion of the parcel. The Corona Yacht Club previously operated as an outdoor event venue that hosted weddings, quinceañeras, birthdays, and Coachella Festival related events. The site is also the location of a palm tree farm which also was the location of a fire incident in 2022.

The property ownership has shifted and the current owner/applicant, Edwart Rostamian, is interested in securing entitlements that allow special event operations to resume once again at the site and is awaiting City approval of the entertainment permit. Staff has met several times since the entertainment permit was submitted to the City to inspect the site and consistently observed unpermitted site, structural and electrical improvements during each visit. Furthermore, several unpermitted RVs were observed on-site and occupied for living purposes. The applicant is working with the City Building Official to ensure improvements at the site are permitted and inspected.

The subject property is in the Urban Neighborhood District of the General Plan, which includes allowed uses of residential at a density of 20-38 du/acre. The proposed use is consistent with the General Plan Vision of Subarea 11 Commercial Entertainment District that will contain much of the new development that attracts visitors to Coachella, including destination retail, hotels and resorts, and entertainment uses. The policies of the subarea encourage the City to act with strong discretion when approving projects, seeking unique, destination-oriented and visitor-serving entertainment and retail uses that would be enhanced by the subarea’s location. The proposed

Item 27.
special event venue would create a destination-oriented use. The applicant expressed future plans for multi-family residential and hotel development on the site.

Entertainment permits are permitted under Chapter 5.24 of the Coachella Municipal Code under Title 5 (Business Licenses and Regulations). Application for an entertainment permit require an investigation of the application by the City Manager and consideration of the proposal at a public hearing by the City Council. If the City elects to grant the entertainment permit, it may impose conditions that include:

1. The days and hours during which the entertainment establishment may operate.

2. The total number of persons including employees and entertainers allowed during its operation.

3. Traffic control measures including the number of parking spaces required for the entertainment establishment.

4. Noise control measures required in the entertainment establishment.

5. Security or safety measures of the patrons, employees, neighbors and general public of the entertainment establishment, including the number of security personnel which may be altered by the chief of police.

6. The placement and utilization of hand-held metal detectors at each entrance to the entertainment establishment for the purpose of ascertaining and removal of weapons from each and every person entering the entertainment establishment to the satisfaction of the chief of police.

DISCUSSION/ANALYSIS:

The applicant, Edwart Rostamian, submitted a request for an entertainment permit to allow the operation of an outdoor entertainment venue on a 20-acre site at 46600 Tyler Street. The zoning designation of the commercial center where the store is proposed is within the U-N (Urban Neighborhood) zone. The entertainment venue would accommodate a range of events that would be proposed to operate Monday-Thursday 9 a.m. to 12 p.m. and Friday-Sunday 10 a.m. to 2:00 a.m. and accommodate up to 500 guests.

Item 27.

Staff contacted the Lieutenant Vasquez with the Riverside County Sheriff regarding any concerns for the proposed business that the City Council may want to consider when making findings or including conditions of approval for the entertainment permit. Lieutenant Vasquez expressed concern about late night events on Sunday.

Hours of Operation:

The applicant has indicated event operating hours would be Monday-Thursday 9 a.m. to 12 p.m. and Friday-Sunday 10 a.m. to 2:00 a.m.

Environmental Setting:

The subject site is a vacant site that is substantially surrounded by urban uses, with adjoining zoning and land uses as follows:

North: General Commercial and Vista Del Agua Specific Plan Commercial Uses/ Residential uses.

South: Urban Neighborhood/ estate residential uses
East: Vista del Agua Specific Plan and vacant land
West: Vacant/ (R-C, Regional Commercial)
Site Plan / Parking and Circulation:

The site is accessed Tyler Street which is a Collector Street on the City’s circulation plan, which at full construction would accommodate 4 vehicular lanes and bike lanes. The existing Tyler Street is in good condition with two vehicular lanes and an improved roadway about 25 feet wide with unpaved shoulders. Vehicular access to the subject site would occur from a 692-foot long driveway and is required to be improved to 30’ wide. The driveway provides circulation around the event venue located toward the northeast portion of the parcel. A secondary driveway Tyler Street entrance exists on-site and is required for emergency purposes. There are two areas proposed parking areas a smaller one at the north side of the property for 10 parking spaces including 5 ADA spaces and a larger parking area that accommodates 122 parking spaces. The parking ordinance requires 150 parking spaces based on the assembly standards of one space for every 21 sq. ft. of assembly area. The total assembly area is assumed at 3,150 sq. ft.

The event area is largely elevated and centralized around an existing lake with existing improvements that include a covered patio (3,150 sq. ft.), deck (3,000 sq. ft.), walkways that circulate around the lake, restroom buildings, and an existing bridge to an island on the lake. A new 6,740 sq. ft. deck is proposed at the southside of the lake. Large ceremonies would be held on an existing turf area (2,563 sq. ft.) to the west of the elevated areas. The applicant identified a maximum occupancy of 500 guests. Due to the parking constraints on the proposed site plan, City staff will limit maximum occupancy to 275 persons.

Item 27.

Figure 1: Event Area around existing lake
Security:

The applicant proposes the use of on-site licensed security for all events and proposed to include 1 security guard for every 50 people. All private events that lease from the applicant will be required to use licensed security. The applicant is required to increase security personnel based on recommendations by the City Manager or Coachella Police.

Noise
The special event activities with use of amplified music are proposed and would generate noise on-site and therefore the applicant engaged Noise Monitoring Services to prepare a noise analysis.

The noise analysis was prepared to determine the maximum noise level that can be generated by the event venue to be consistent with the City of Coachella Municipal Code noise standards by identifying the noise impact to existing receptors that include residences to the north zoned General Commercial and residences to the south zoned Urban Neighborhood. The analysis assumed a maximum of 25 loudspeakers distributed around the edge of the lake and a noise model that accounts for factors such as the location, noise sources, terrain, buildings and barriers at the site.

The study concluded that the amplified sound from loudspeakers at the event venue could generate a maximum noise level of 76 dBA before 10:00 pm and no higher than 66 dBA after 10 p.m. when measured 25 feet in front of the loudspeakers for compliance with the City’s noise ordinance.

Recommendations from the study have been added as conditions of approval of the project. A condition of approval requires amplified sound for events under this permit to end by 10 p.m.

Item 27.

ENVIRONMENTAL REVIEW:

A determination was made by the Development Services Department that the project will not have a significant impact on the environment and determined that the proposed project is categorically exempt from environmental review pursuant to the guidelines of the California Environmental Quality Act as an “Existing Facilities” project (CEQA Guidelines, Section 15301a). The proposed project consists of the operation, licensing and minor alteration of an existing location involving no expansion of existing or former commercial use on the property. The subject site has been used as a special event venue and no expansions of floor area are proposed.

FISCAL IMPACT:

As conditioned, the proposed Entertainment Permit would not have any fiscal impacts upon the City of Coachella finances. There are no additional fees collected for this type of business other than normal licensing fees for the business. Visitor serving facilities such as the special event venue would support the local economy and small businesses that provide services for the special event venue.

ALTERNATIVES:
1) Adopt Resolution No. 2022-37 approving Entertainment Permit 22-04 with the staff recommendations.
2) Adopt Resolution No. 2022-37 with new or modified conditions of approval. 3) Make findings and Deny the Entertainment Permit.
4) Continue the item and provide staff direction.

RECOMMENDED ALTERNATIVE
Based on the analysis contained herein and the findings listed below, staff is recommending that the City Council approve Alternative #1.

Introduction
This report details the noise analysis performed for the Coachella Valley Events Center at 46600 Tyler Street in Coachella. The events center is an existing facility that is undergoing remodeling. The facility currently includes various guest congregation areas, a covered deck, patio, a lake, a stage an onsite building and offices. The remodeled facility will include the addition of parking areas, a loading zone and bathrooms. It is proposed that amplified music will be played at the stage and a distributed speaker system will be installed around the lake, which will play ambient music during events. The maximum capacity of the facility will be 750 people and the proposed operating hours are 11 am to 2 am. The noise study was performed to estimate noise levels of events and to determine the noise control measures required for compliance with the City’s noise ordinance. This report provides the City of Coachella Municipal Code noise standards, the existing noise levels at the site, estimated noise levels during an event, an assessment of impact, and recommendations to ensure compliance with the noise standards. The location of the project site is shown in Figure 1.

City of Coachella Noise Standards
Chapter 7.04 of the City of Coachella Municipal Code contains exterior sound limits that apply to the project. These limits are provided below:

7.04.030 - Sound level limits as related to fixed noise sources.

A. Regardless of whether an objective measurement by sound level meter is involved, it shall be unlawful for any person to make, continue, or cause to be made or continued, within the city limits any disturbing excessive or offensive noise or vibration which causes discomfort or annoyance to any reasonable person of normal sensitivity residing in the area or that is plainly audible at a distance greater than fifty (50) feet from the sources point for any purpose. The following ten-minute average sound level limits, unless otherwise specifically indicated, shall apply as indicated in the following table as it relates to a fixed noise source or leaf blowers pursuant to Section 7.04.075.

B. If the measured ambient noise level exceeds the applicable limit as noted in the table in subsection (A) of this section, the allowable average sound level shall be the ambient noise level. The ambient noise level shall be measured when the alleged noise violation sources are not operating.

C. The sound level limit between two zoning districts shall be measured at the higher allowable district.

7.05.020 - Loud or unruly gatherings—Public nuisance.

It shall be unlawful and a public nuisance to conduct a gathering of ten (10) or more persons on any private property in a manner which constitutes a substantial disturbance of the quiet enjoyment of private or public property in a significant segment of a neighborhood, as a result of conduct constituting a violation of law. Illustrative of such unlawful conduct is excessive noise or traffic, obstruction of public streets by crowds or vehicles, public drunkenness, the service of alcohol to minors, fights, disturbances of the peace, litter. A gathering constituting a public nuisance may be abated by the city by all reasonable means including, but not limited to, an order requiring the Zone Time

Noise measurements conducted to determine compliance with the above noise limits are performed at the property line of the property affected by the noise.

In addition to the objective noise limits above, the Municipal Code provides the following subjective noise regulations:

7.04.040 - Prohibited noise generally.

A. It is unlawful for any person or property owner within the city of Coachella to make, cause, or continue to make or cause, loud, excessive, impulsive or intrusive sound or noise that annoys or disturbs persons of ordinary sensibilities.

B. The factors, standards, and conditions that may be considered in determining whether a violation of the provisions of this section has been committed, include, but are not limited to, the following:

1. The level of the noise;

2. The level and intensity of the background (ambient) noise, if any;

3. The proximity of the noise to residential or commercial sleeping areas;

4. The nature, density and zoning of the area within which the noise emanates;

5. The density of inhabitation of the area within which the noise emanates;

6. The time of day and night the noise occurs;

7. The duration of the noise;

8. Whether the nature of the noise is natural or unnatural;

9. Whether the noise is constant, recurrent or intermittent; and

10. Whether the noise is produced by a commercial or noncommercial activity.

The City provides an exemption for outdoor gatherings, public dances, shows and sporting and entertainment events; provided the events are authorized by the city.

To ensure a conservative analysis, and to reduce the possibility of noise disturbances at nearby residences, our analysis assumes that the events center must comply with the residential noise limits at all nearby residences even though the residential properties to the north are within a commercial zone.

Page 410 ends

Existing Noise Environment
Ambient noise in the area is primarily due to traffic on I-10 and nearby surface streets, aircraft and wildlife. Two 24-hour ambient noise measurements were obtained at the north and south property boundaries of the site, at locations representative of the nearest residences.

The measurements were obtained with model SVAN 971 type 1 precision sound level meters manufactured by Svantek, which were calibrated before the measurements. The locations of the measurement are provided in Figure 1. The measurements were obtained from 3:00 pm on April 13, 2024 for a period of 24-hours. Figure 3 provide the 10 minute average noise levels measured at each location for the entire measurement period. Table 3 provides a summary of the results. This table provides the range of measured sound levels for the daytime and nighttime operational hours.

Table 1 Summary of ambient noise measurement results
Location Time period
Range of 10-minute A-weighted average
sound levels (dBA)
Location 1
Daytime operation (11 am to 10 pm) 46.3 to 59.9

Events Center Noise Analysis
The sound sources associated with the project include guests talking at the various onsite congregation areas, amplified music at the stage, and music played though the distributed speaker system around the lake. A computer noise model of the events center was generated to estimate the worst-case noise levels produced by the facility. The worst-case noise levels would occur during a full-capacity event, with guests generating noise through talking and shouting, amplified music at the stage and ambient music played though the speaker system around the lake. It was assumed there will be a maximum of 25 loudspeakers distributed around the edge of the lake (each directed towards the center of the lake) and two loudspeakers at the stage (directed west).

The noise model was constructed using SoundPlan three-dimensional noise modeling software, which takes into account the locations, levels and frequency spectra of the noise sources, and the terrain, buildings and barriers at the site. The model utilized reference sound measurements conducted at similar facilities.

Based on our analysis it was determined that the loudspeakers at the stage will be the greatest contributor of offsite noise. While the noise from guests and distributed speaker system will contribute to overall noise levels, compliance with the City’s noise limits can be achieved by controlling noise from the stage alone. Our analysis involved determining maximum sound levels of loudspeakers to ensure compliance with the City’s noise limits. The loudspeakers at the stage must produce a sound level no higher than 76 dBA before 10 pm, and no higher than 66 dBA after 10 pm, when measured 25 ft in front of the loudspeakers.

A summary of the results of exterior noise level analysis is provided in Table 2. The data provided in the table demonstrates compliance with the noise limits at all nearby properties during a worst-case event.

A noise map showing the worst-case noise levels of an event during the daytime hours (before 10 pm), with implementation of the 76 dBA daytime stage loudspeaker sound level limit, is provided in Figure 4.

A noise map showing the worst-case noise levels of an event during the nighttime hours (after 10 pm), with implementation of the 66 dBA nighttime stage loudspeaker sound level limit, is provided in Figure

Recommendations
The following noise control recommendations are provided to ensure compliance with the City of Coachella exterior noise limits:

1. The sound level of the music sound system at the stage should be adjusted so that the sound level is no higher than 76 dBA before 10 pm and no higher than 66 dBA after 10 pm when measured at a distance of 25 feet in front of the speakers. The sound system level control should be set so that the speaker sound level cannot exceed this requirement.

2. The sound level of the distributed ambient music sound system around the lake should be adjusted so that the sound level is no higher than 65 dBA at a distance of 5 feet in front of any single loudspeaker. The sound system level control should be set so that the loudspeaker sound level cannot exceed this requirement. The loudspeakers should be oriented so that they are directed towards the center of the lake.

3. Sound levels should be measured during an event to verify that the City’s noise limits are not exceeded. At a minimum, sound levels should be measured at the two measurement locations identified in Figure 1. If the event extends beyond 10 pm, measurements should be obtained after this time. If an exceedance of the noise limit is measured, the loudspeaker level limiters should be adjusted down to ensure that the noise limit is achieved. The measurements should be made in accordance with the requirements of the City of Coachella Municipal Code.

Conclusion
This report provides an analysis of the noise levels associated with the proposed Coachella Valley Events Center. Our analysis indicates that, with the implementation of the recommendations included in this report, the operational noise levels will comply with the City’s daytime and nighttime Municipal Code noise limits at all nearby properties. Furthermore, the noise levels will be lower than the existing ambient background noise levels in the area.

Glossary of Terms
The following is a list of definitions of terms commonly used in the field of acoustics. Some, or all, of these terms may have been used in the preceding report:

Ambient Noise: The all-encompassing noise associated with a given environment at a specified time, usually a composite of sound from many sources both near and far.

Average Sound Level: See Equivalent-Continuous Sound Level.

A-Weighted Sound Level, dB(A): The sound level obtained by use of A-weighting. Weighting systems were developed to measure sound in a way that more closely mimics the ear’s natural sensitivity. The A- weighting system is incorporated into the sound level meter to alter its sensitivity relative to frequency so that the instrument is less sensitive to noise at frequencies where the human ear is less sensitive and more sensitive at frequencies where the human ear is more sensitive. (Refer to Figure l-l for typical noise source levels.) Community Noise Equivalent Level (CNEL): A 24-hour A-weighted average sound level which takes into account the fact that a given level of noise may be more or less tolerable depending on when it occurs. The CNEL measure of noise exposure weights average hourly noise levels by 5 dB for the evening hours (between 7:00 p.m. and 10:00 p.m.), and 10 dB between 10:00 p.m. and 7:00 a.m., then combines the results with the daytime levels to produce the final CNEL value. It is measured in decibels, dB. (Refer to Figure l-2 for typical noise exposure levels.) CNEL: See Community Noise Equivalent Level.

Day-Night Average Sound Level (DNL or Ldn): A measure of noise exposure level that is similar to CNEL except that there is no weighting applied to the evening hours of 7:00 p.m. to 10:00 p.m. It is measured in decibels, dB. (Refer to Figure I-2 for typical noise exposure levels.)
Daytime Average Sound Level (Leq(12)): The time-averaged A-weighted sound level measured between the hours of 7:00 am to 7:00 pm. It is measured in decibels, dB.

Decay Rate: The time taken for the sound pressure level at a given frequency to decrease in a room. It is measured in decibels per second, dB/s.

Decibel (dB): The basic unit of measure for sound level.

Direct Sound: Sound that reaches a given location in a direct line from the source without any reflections.

Divergence: The spreading of sound waves from a source in a free field, resulting in a reduction in sound pressure level with increasing distance from the source.

Energy Basis: This refers to the procedure of summing or averaging sound pressure levels on the basis of their squared pressures. This method involves the conversion of decibels to pressures, then performing the necessary arithmetic calculations, and finally changing the pressures back to decibels.

Equivalent-Continuous Sound Level (Leq): The average sound level measured over a specified time period. It is a single-number measure of time-varying noise over a specified time period. It is the level of a steady sound that, in a stated time period and at a stated location, has the same A-weighted sound energy as the time-varying sound.

For example, a person who experiences an Leq of 60 dB(A) for a period of 10 minutes standing next to a busy street is exposed to the same amount of sound energy as if he had experienced a constant noise level of 60 dB(A) for 10 minutes rather than the time varying traffic noise level. It is measured in decibels, dB.

Fast Response: A setting on the sound level meter that determines how sound levels are averaged over time. A first sound level is always more strongly influenced by recent sounds, and less influenced by sounds occurring in the distant past, than the corresponding slow sound level. For the same non-steady sound, the maximum first sound level is generally greater than the corresponding maximum slow sound level. Fast response is typically used to measure impact sound levels.

Field Impact Insulation Class (IIC): A single number rating similar to the impact insulation class except that the impact sound pressure levels are measured in the field.

Field Sound Transmission Class (FSTC): A single number rating similar to sound transmission class except that the transmission loss values used to derive this class are measured in the field.

FIIC: See Field Impact Insulation Class.

Flanking Sound Transmission: The transmission of sound from a room in which a source is located to an adjacent receiving room by paths other than through the common partition. Also, the diffraction of noise around the ends of a barrier.

Frequency: The number of oscillations per second of a sound wave (i.e., the number of cycles per second). It is measured in hertz. Hz.

FSTC: See Field Sound Transmission Class.

Hertz (Hz): See Frequency.

Hourly Average Sound Level (HNL): The equivalent-continuous sound level, Leq, over a 1-hour time period. It is measured in decibels.

Impact Insulation Class (IIC): A single number rating used to compare the effectiveness of floor/ceiling assemblies in providing reduction of impact-generated sounds such as the sound of a person walking across the upstairs floor.

Impact Noise: The noise that results when two objects collide.

Impulse Noise: Noise of a transient nature due to a sudden impulse of pressure like that created by a gunshot or a balloon bursting.

Insertion Loss: The decrease in sound power level measured at the location of the receiver when an element (e.g., a noise barrier) is inserted in the transmission path between the sound source and the receiver. It is measured in decibels.

Inverse Square Law: A rule by which the sound intensity varies inversely with the square of the distance from the source. This results in a 6 dB decrease in sound pressure level for each doubling of distance from the source.

Noise Reduction Coefficient (NRC): A single number rating of the sound absorption properties of a material. It is the average of the sound absorption coefficients at 250, 500, 1000, and 2000 Hz, rounded to the nearest multiple of 0.05.

Normalized Noise Isolation Class (NNIC): A single number rating similar to the noise isolation class except that the measured noise reduction values are normalized to a reverberation time of 0.5 seconds.

Octave-Band Sound Level (Octave-Band Level): For an octave frequency band, the sound pressure level of the sound contained within that band. It is measured in decibels.

One-Third Octave: The frequency interval between two sounds whose frequency ratio is 21/3 (1.26). For example, the frequency interval between 200 Hz and 250 Hz is one-third octave.
