Dear Ladies and Gentlemen:

o CC EIVE PSEP172002
My wife and I reside at 77-600 Avenida Fernando where we have lived for 15 years. Our
house and property are next door to the Davis residence at 77-500 Avenida Fernando.
Both our properties are located across the street from the La Quinta Hotel & Resort.
Approximately ten years ago we obtained a variance from the City granting us approval
to install a wall along the front and side of our property. Since that time the truck traffic
on Fernando has increased dramatically.
It is our understanding that Mr. & Mrs. Davis are now seeking a similar variance for a
wall along the front of their property. This letter is to advise you that we are entirely
supportive of the Davis application as the very high wall contemplated would help deflect
some of the noise and exhaust fumes from the truck traffic. We would strongly urge you
to grant the permit to construct the wall that Mr. Davis is requesting.
Please feel free to call us if you have any questions.

Subject: 'La Quinta Resort Traffic and Noise Issues
Dear Mr. Derr:
This letter provides our assessment of the. Traffic and Noise issues
associated with The La Quinta Resort on the neighbo.rinq
residential property located at 77-500 Avenida Fernando. Exhibit -A
illustrates the project location and Exhibit B shows the project study
area. Under current conditions, Avenida Fernando is used by the
La Quinta Resort for commercial deliveries, employee shuttle
services, trash pickups, maintenance activities and hotel guest
traffic. The photos included in Appendix "A" show the vehicle
activity observations. In addition, Avenida Fernando provides
access to The Enclave, Mountain Estates and Tennis Villa
residential communities as well as driveway access for 77-500
Avenida Fernando. As a result of the early morning heavy vehicle
activity, the employee shuttle services and commercial deliveries,
the neighboring residential homes have expressed concerns
related to noise and traffic issues.
TRAFFIC IMPACT ASSESSMENT
To assess the traffic impacts associated with the operation of the
La Quinta Resort, Urban Crossroads, Inc. reviewed the La Quinta
Resort Specific Plan Amendment #4 Traffic Impact Analysis and
surveyed the traffic conditions along Avenida Fernando on April 15,
2002.
Mr. Jay Derr

Road Capacity
According to the City of La Quinta General Plan, Avenida Fernando is a private road
and as such has a functional capacity of no more than 3,000 average daily vehicles,
the limit for an unclassified local public road). The existing curb to curb pavement
width is 30 feet, slightly narrower than the standard for a local public road and narrower
than the standard for a private road. According to the La Quinta Resort Specific Plan
Amendment #4 Traffic Impact Analysis, prepared by Endo Engineering in August 1997,
Avenida Fernando was projected to serve approximately 3,350 vehicles, and "exceed
the capacity for a local street by 11.7 percent."
According to the Endo Study, the capacity of a local street is determined by the
environmental" capacity of the roadway, which reflect the need to reduce traffic in
areas where vehicles back out of driveways and pedestrian activity occurs. The
environmental" capacity incorporates consideration of the character of the existing
residential development in the area, public safety concerns such as emergency access
and bicycle and pedestrian hazards, and the perception of area residents that high
environmental standards should be set to maintain their quality of life.
The study also stated that a residential street must also serve the needs of the people
who live on the street. These concerns typically include: (1) being able to safely ingress
and egress their property, (2) safe pedestrian travel along and crossing .the street, (3)
safety for school -aged children and (4) noise issues.
Vehicle Mix
Traffic conditions on local residential streets are predominately associated with private
vehicle activity. The majority of the commercial vehicles and heavy truck activity is
intended to occur on arterial roadways. As part of the General Plan Update, the City of
t
Mr. Jay Derr
BUCK & GORDON

La Quinta identified three locations that were used to identify the distribution
percentages of automobile, medium trucks and heavy trucks. The vehicle mix survey
was taken on September 9, 1999 at 42nd Street east of Adams, Washington Street
north of 50th Avenue and Jefferson Street north of Avenue 54. Table 1 presents the
City of La Quinta hourly traffic flow distribution. The results of this survey concluded
that trucks represent 2% of the total daily traffic, and autos comprise the remaining 98%
of the traffic. These counts reflect the vehicle mix on an'arterial road that is designed to
carry a higher proportion of heavy vehicles.
As noted above, Avenida Fernando is a private street, a lesser classification than the
arterials described in the previous paragraph. As such, it should have a vehicle mix
with. fewer trucks. To identify the vehicle mix on Avenida Fernando, a manual count
was taken for 15 minutes during the early morning delivery hours on April 15, 2002.
Table 2 presents a summary 'of the manual .vehicle mix count. The count data
presented in Table 2 indicates that private automobile traffic represents only 53% of the
total traffic monitored during this period. The. remaining 47% of the vehicle traffic
consisted of a variety of commercial traffic, medium trucks, heavy trucks and
maintenance carts. This count reflects a far greater percentage of trucks on this private
street than the counts for the nearby arterials..
This manual count suggests that the vehicle activity on Avenida Fernando is
inconsistent with the character and nature of a private local residential street. In
addition, this vehicle mix may impact the local residential street structural roadway
pavement section. In other words, this street was likely not designed to accommodate
vehicle traffic with heavier axle loadings. These loads may result in a higher traffic
index (used to design the roadway base and pavement section thickness). It is unlikely
this local road was designed for utilization by the substantial number of medium and
heavy duty trucks on Avenida Fernando.
Mr. Jay DerrL
BUCK & GORDON

The manual vehicle mix counts were collected to identify existing vehicle mix during the
morning studied. According to the adjacent residential property owner, the morning
studied did not have the level of truck activity that often occurs during the peak season
Thanksgiving -Easter). To better understand the actual daily vehicle mix, a 24-hour
tube count may be appropriate, especially during the peak activity season.
NOISE IMPACT ASSESSMENT
A noise assessment has been completed to determine the noise impacts associated with
the current operations of the La Quinta Resort in the neighboring residential community.
The purpose of this noise assessment is to identify the noise impacts experienced at 77-
500 Avenida Fernando. To evaluate the "worst-case" noise condition, existing ambient
noise level measurements were taken between 6:50 a.m. and 9:00 a.m. on a typical
weekday. This particular study was conducted just after the end of the peak season.
Peak season activity and noise levels may, in fact, be greater than those measured in this
study. Additional monitoring during the peak season would be the only way to verify this.
The noise level measurements taken on the residential property (approximately 30 from
the street centerline of Avenida Fernando) ranged from 51.5 dBA L50 to 52.5 dBA Leo•
Based on these results, the noise impacts associated with the La Quinta Resort currently
exceed the City of La Quinta exterior nighttime (10:00 p.m. to 7:00 a.m.) residential noise
ordinance standard of 50 dBA.
Measurement'Procedure and Criteria
Noise measurements were taken using a LARSON-DAVIS. Model 700 precision
integrating sound level meter, programmed, in "slow" mode, to record noise levels in "A"
weighted form. The sound level meter was .calibrated before and after the monitoring
using a LARSON-DAVIS calibrator, Model CAL 150. The sound level meter and

microphone were mounted on a tripod, five feet above the ground and equipped with a
windscreen during all measurements.
Noise Measurement Locations
Noise monitoring locations were selected based on their respective impact potential.
Site 1 was located approximately 30 feet from the centerline of Avenida Fernando
adjacent to the existing hedge row. Site 2 was located at the fagade of 77-500 Avenida
Fernando. Exhibit C identifies the noise monitoring locations.
Noise Measurement Results
The results of the ambient noise level measurements are presented in Table 3. Each
site was monitored for a minimum time period of 10 minutes based on the suggested
measurement duration outlined in Table N-3320.1 of the Caltrans Technical Noise
Supplement. Since the variations in the displayed Leq were less than 0.5 dBA, each
measurement was concluded after a ten-minute duration period.
The existing noise levels in the residential community, consist of vehicle noise from
Avenida Fernando, truck deliveries, trash truck activities, employee shuttle drops that
occur every 10 minutes, truck backup alarms, and background generators / air
conditioning units for the temporary conference facilities.
Noise Fundamentals
Noise has been simply defined is "unwanted sound." It is an undesirable by-product of
transportation systems and industrial activities within a community. The full effect of such
noise on individuals and the community will vary with its duration, its intensity, and the
tolerance level of the exposed individuals. Physical health, psychological well-being,
Mr. Jay Derr
BUCK & GORDON
June 17, 2002

social cohesion, property values and economic productivity can- all be affected by
excessive..amounts of noise.
Airborne sound is the .result of a very rapid change in air pressure from the surrounding
normal" atmospheric pressure. The combination of noise from all sources near and far is
the Ambient Noise Level'. For purposes of this discussion, the ambient noise level at a
given . location is termed "environmental noise". Understanding environmental noise
requires some familiarity with the physical description of noise. The important physical
characteristics of sound include its frequency range, intensity/loudness and
temporal/time-varying aspect. The decibel A -weighted level (dBA), and Community Noise
Equivalency Level (CNEL) are all units of measurement used to describe and numerically
weight noise. The following terms common in noise evaluation. work are defined for the
reader's information:
A -Weighted Sound Level - (dBA): The sound pressure level in decibels are
measured on a sound meter using the A -Weighting filter network. The A -
Weighting filter de-emphasizes the very low and very high frequency
components of the sound in a manner similar to the response of the human ear
and gives accurate correlation with subjective reactions to noise.
Ambient Noise Level: The composite of noise from all sources near and far. In
this context, the ambient noise level constitutes the normal or existing level of
environmental noise at a given location.

Decibel (dB): A unit for measuring the amplitude of sound, equal to 20 times the
logarithm to the base 10 of the ratio of the pressure of the sound measured to the
reference pressure, which is 20 micro -Pascal's.
Equivalent Energy Level (Leg): The sound level corresponding to a steady state
sound level containing the same total energy as a time varying signal over a given
sample period.
Noise: Any unwanted sound or sound which is undesirable because it interferes
with speech and hearing, or is intense enough to damage hearing, or is otherwise
annoying.
Sound Level Meter: An instrument, including a microphone, an amplifier, an
output meter, and frequency weighing networks for `the measurement and
determination of noise and sound levels.
Noise Standards
The City of La Quinta has identified two separate types of noise sources: (1)
transportation, and (2) stationary. To control transportation related noise sources such as
freeways, airports and railroads, the City of La Quinta has established guidelines for
acceptable community noise levels in the Noise Element of the General Plan. The most
effective method to control community noise .impacts from non -transportation noise
sources (such as speakerphones, trash compactors, air-conditioning units, etc.) is
through the application of a community noise ordinance. In the context of this noise
analysis, the noise impacts associated with the La Quinta Resort are controlled by the
City noise ordinance.
Mr. Jay Derr
BUCK & GORDON
June 17, 2002
Page 8
Section 9.100.200 of the City of La Quinta Municipal Code outlines performance
standards to control stationary source / non -transportation related noise impacts in
residential areas. The standards establish a maximum allowable exterior noise level of
60 dBA for residential living areas during typical daytime hours of 7 a.m. to 10 p.m.. To
account for the increased noise sensitivity during the nighttime hours of 10 p.m. to 7 a.m.,
the noise standards are reduced to 50 dBA for the exterior residential living areas. The
City of La Quinta Exterior noisestandards are included in Appendix "B".
Noise Analysis
A comparison of the existing noise level measurements and the nighttime (10:00 p.m. to
7:00 a.m.) noise level standards indicates that the current noise levels before 7:00 a.m.
exceed the City of La Quinta Noise ordinance standards. The noise impacts experienced
in the neighboring residential community are primarily associated with the commercial,
medium and heavy truck activity and employee shuttles on Avenida Fernando. The noise
impacts associated with heavy trucks are not consistent with the residertial character of
the local street that provides access to 77-500 Avenida Fernando. These unmitigated
impacts result primarily from the heavy truck activity the produces noise levels
substantially higher than the. typical automobiles one would expect on a local residential
street.
The activities at La Quinta Resort begin in the early morning well before 7:00 a.m. r
The
activities include truck deliveries, trash. truck activities, employee shuttle drops that
occur every 10 minutes, truck backup alarms, and background generators / air
conditioning units for the temporary conference facilities.

SUMMARY OF RECOMMENDATIONS
The following recommendations were developed to minimize the potential noise impacts
resulting from the La Quinta Resort.
1. Operations at the La Quinta Resort shall comply with the City of La Quinta noise
ordinance standards. . Modifications to the operations should be required as
necessary to meet these standards.
2. All vehicles or equipment fixed or mobile shall be equipped with properly operating
and maintained mufflers and best efforts should be made to locate stockpiling,
vehicle staging and maneuvering areas as far as practicable from existing
residential dwellings on Avenida Fernando.
3. Construct a noise barrier capable of.breaking the line -of -sight from a heavy truck
with a stack height of 11.5 feet at 77-500 Avenida Fernando.. We recommend a
barrier height in excess of the truck stack height to best accomplish adequate
noise attenuation. The designed noise barrier may only be accomplished if the
barriers weight is at least.3.5 pounds per square foot of face area and have no
decorative cutouts or line -of -site openings between shielded areas and the
roadways. The barrier must present a solid face from top to bottom. Unnecessary
openings or decorative cutouts should not be made. All gaps (except for weep
holes) should be filled grout or caulking.
4. An asphalt rubber hot mix (ARHM) overlay should be considered to reduce the
noise impacts associated with vehicle tires traveling over pavement for Avenida
Fernando. Studies have shown that the use of an asphalt rubber hot mix (ARHM)
overlay can provide a significant 4 dBA noise reduction in traffic noise levels as
Mr. Jay Derr
BUCK & GORDON
June 17, 2002
Page 10
compared to the conventional asphalt overlay. This noise attenuation represents a
60% reduction in the traffic noise energy, and is a results in a clearly perceptible
decrease in traffic noise
5. Reduce the noise impacts associated with'the employee drop-off by relocating the
employee staging area to less sensitive location.
6. Operate Clean -air vehicle shuttles and eliminate the use of the current diesel
shuttle buses.
7. For special events operate quiet portable generators for use of the temporary
conference facilities. These generators should be located away from the sensitive
residential receptors on Avenida Fernando, perhaps in the parking area underneath
the convention center or on the south side of the convention center. These quiet
generators would substantially reduce the noise impacts currently produced by the
standard" generators.
