The McReynolds property lies south of Palomar Airport Road, within Zone 20 of the city
of Carlsbad (Figures 1 and 2). It is about 2,000 feet west of future Alga Road and 2,000
feet east of Interstate 5. The property was included in the Specific Plan prepared for
Zone 20.
The property is approximately 34.3 acres and consists of the northern extent of a finger
of land overlooking Encinas Canyon to the north. The northern extent of the project area
is within the 60 A-weighted decibel community noise equivalent level (dBA CNEL)
contour for the McClellan-Palomar Airport.
With the adoption of the environmental impact report (EIR) for the Specific Plan for
Zone 20, conditions were established for assessing noise impacts. Planning Commission
Resolution Number 3525 presented four conditions to address potential adverse noise
effects on projects within Zone 20. These conditions were superseded by the
development of the City of Carlsbad Draft Noise Guidelines Manual, and revisions
outlined for the Noise Element of the General Plan.. The Noise Element required that a
noise study be submitted for all discretionary applications for residential projects
potentially within the 60 dBA contour of a prime arterial or within the 55 dBA contour
for a non-prime arterial circulation element road. For the current project, this
requirement necessitates a noise study for potential effects from Palomar Airport Road
and Paseo del Norte. The former is a prime arterial and the latter a secondary arterial
circulation element roadway.
Potential sources of noise analyzed in this report include traffic on Palomar Airport Road
and Paseo del Norte, and aircraft operating out of McClellan-Palomar Airport. The
analysis applied the criteria proposed in the draft Noise Element of the General Plan and
the supporting procedures and information in the City of Carlsbad Draft Noise
Guidelines Manual (1993).
As a result of the analysis, a limited area at the northern end of the project could be
exposed to noise levels in excess of 60 dBA CNEL as a result of traffic on Palomar
Airport Road. Noise levels from air traffic at Palomar Airport could result in noise levels
on the site of between 60 and 65 dBA CNEL. There are no areas on the project site
which are projected to be in excess of 65 dBA CNEL.
Construction of a noise barrier can reduce exterior noise levels to below the standards set
by the City of Carlsbad. Typical construction practices, with the provision of forced air
circulation or air conditioning, will insure that interior levels are within the noise limits
required by the City. The area is within the Noise Impact Notification Area (NINA)
established in the Comprehensive Land Use Plan for the McClellan-Palomar Airport. As

A. Applicable Standards and Definitions of Terms
Impacts to future and existing sensitive receptors (residences) within the project site were
evaluated in relation to the noise level standards promulgated in the City of Carlsbad's
Noise Element for the General Plan and the Draft Noise Guidelines Manual. The
standards applied for this project are presented in paragraph C.5. of the proposed general
plan element. This policy states:
Enforce the policy of the City that sixty (60) dBA CNEL is the exterior noise level to
which all residential units should be mitigated. Interior noise levels should be mitigated
to 45 dBA CNEL when openings to the exterior of the residence are open or closed. The
CNEL is a 24-hour cumulative measure of community noise exposure based on the A-
weighted decibel. A-weighting is a frequency correction that correlates noise levels with
the frequency response of the human hearing system. The CNEL adds 10 decibels (dBA)
to the average noise levels (L^) between the nighttime hours of 10:00 P.M. and 7:00 A.M.
and 5 dBA to the evening hours between 7:00 P.M. and 10:00 P.M. to account for the
added sensitivity to noise during these time periods.
B. Traffic Noise Analysis
Traffic noise generated by circulation element roadways on-site were analyzed using the
STAMINA 2.0 model from Vanderbilt University (1991). This model is a computerized
version of the Federal Highway Administration Noise Prediction Model (FHWA-RD-77-
108) (1979), which uses California vehicle noise emission (Calveno) levels (California
Department of Transportation [Caltrans] 1983). This model calculates noise levels at
selected receiver locations using input parameter estimates such as projected hourly
average traffic rates; vehicle mix, distribution, and speed; roadway lengths and gradients;
distances between sources, barriers, and receivers; and shielding provided by intervening
terrain, barriers, and structures.
Future average daily traffic volumes (ADTs) for the circulation element roadways
(Palomar Airport Road and Paseo del Norte) were obtained from the City (Wickham,
personal communication, 1994) and were based on information from the San Diego
Association of Governments. Traffic volumes for Palomar Airport Road east of Paseo
del Norte are projected to be 41,500 ADTs in the year 2010. On Paseo del Norte, south
of Palomar Airport Road, volumes are predicted to be 10,500 ADT. The speeds used
were was 55 and 35 miles per hour (mph), respectively.

Traffic mixes for the roadways surrounding the project were obtained from the Draft
Noise Guidelines Manual (1993). The traffic mixes were the average mixes for truck
routes and nontruck routes recorded in the city. Palomar Airport Road was identified as
a truck route, with an average 95.24 percent cars, 3.52 percent medium trucks, and 1.24
percent heavy trucks. Paseo del None was a non-truck route with an average 97.89
percent cars, 1.83 percent medium trucks, and 0.28 percent heavy trucks.
Day/evening/night percentages used were 85 percent, 2 percent, and 13 percent,
respectively. Using these figures, the CNEL is approximately 1.2 decibels higher than
the daytime hourly L^.
Pad elevations and on-site circulation element roadway alignments and elevations were
obtained from the 1"=100' scale tentative map supplied by the project engineer, and a
1"=400' scale orthrophoto with topography for the general areas. Receivers, roadways,
and barriers were input into the STAMINA program using three-dimensional
coordinates. State plane coordinate system and elevations were used as the coordinate
base for the analysis.
Exterior traffic noise levels to receptors, placed five feet above ground, were calculated
and the need for mitigation measures to achieve City standards was evaluated.
Figure 3 shows the location of the receptors analyzed along with the topography and lot
configuration for the project Figure 4 provides typical cross sections for the topographic
conditions between the project site and Palomar Airport Road and Paseo del Norte.
C. Aircraft Noise
Operations at McClellan-Palomar Airport number about 19,000 per month (M. Frank,
personal communication, 1992). An operation consists of a takeoff and a landing. The
airport operates 24 hours per day, with about 10 percent of the operations occurring at
night. Weekends are the busiest days. The majority of the aircraft using the airport are
small, private multi-engine propeller planes. There are also some light jets and corporate
planes.
The San Diego Association of Governments has prepared a map of projected noise
contours for the airport (Figure 5). This figure is reproduced in the Draft Noise
Guidelines Manual and is used as the basis for assessing the potential impact form
aircraft overflights in the vicinity of the project This map shows the 60-decibel contour
crossing of the property. The 65 dBA contour lies off the property to the north.
The project is within the NINA for McClellan-Palomar Airport. The NINA is an area
three miles in radius around the airport and the BORILS corridors to the east and west.

The Comprehensive Land Use Plan for McClellan-Palomar Airport Carlsbad California
states:
/
To ensure that new residential discretionary projects are conditioned to
notify new property owners of their proximity to the airport, and that their
property may be subject to aircraft overflight operating from McClellan-
Palomar Airport, the NINA has been established. All new residential
projects located within the NINA ... shall be required to record a notice
concerning aircraft environmental impacts, clarifying that the property is
subject to overflight, sight and sound of aircraft operating from
McClellan-Palomar (SANDAG 1994:13).
The comprehensive plan provides a sample form for this notification, a copy of which is
attached to this report (Attachment 2).

Future Acoustical Environment
Traffic Noise
Figure 6 shows the future unattenuated traffic noise contours on the project. Detailed
results of the STAMINA analyses are provided in Attachment 1. Table 1 presents the
daytime hourly L^ and the CNEL for each receptor. Receptors are labeled consecutively
within lots (e.g., Receptor 291 is the first receptor in Lot 29).
The traffic volumes on Palomar Airport Road would generate noise of 61 dBA CNEL on
the northern area of the project in the year 2010. Combined noise resulting from traffic
on both Paseo del Norte and Palomar Airport Road cause the predicted 55 dBA contour
to occur in the central portion of the property.
Since the Palomar Airport Road will cause predicted noise levels in excess of 60 dBA
CNEL there is a potential for a significant adverse noise impact. Since Paseo del Norte
will not cause predicted noise levels in excess of 60 dBA CNEL, no significant adverse
traffic noise impacts will result from approval of this project.
Future-projected noise contours of McClellan-Palomar Airport show that the 65 CNEL
contour line would not reach the project site. As such it will not exceed the standard set
in the Noise Element of the General Plan.

Mitigation
Because a limited area of the project site will be exposed to noise levels in excess of 60
dBA CNEL, a noise barrier is required to meet the City of Carlsbad criteria. The
construction of a four-foot-high wall or berm in the location is illustrated on Figure 7.
With the inclusion of this barrier, ground floor noise levels due to traffic on Palomar
Airport Road will be below 60 dBA CNEL.
The noise standards for the City of Carlsbad also call for interior levels due to exterior
sources to be below 45 dBA CNEL. Common construction techniques allow for a 15- to
20-decibel reduction when windows are kept closed. With the provision of forced air
circulation or air conditioning in the units exterior noise levels as high as 65 dBA CNEL
would be in conformance with the 45 dBA CNEL standard.
In addition, notification of future property owners in conformance to the Comprehensive
Land Use Plan for the airport on a form similar to that attached to this report will insure
that no adverse impacts occur as a result of air traffic associated with the McClellan-
Palomar Airport.
