South Carlsbad North
The proposed receiver site would extend from approximately the intersection of Palomar Airport
Road and Carlsbad Boulevard, on the north, southward for a distance of approximately 2,800 feet. In
this area, there are no residences or other sensitive noise receptors adjacent to the beach. The nearest
sensitive noise receptors include single residences that are east of Carlsbad Boulevard on Oceanview
Drive, at a distance of approximately 500 feet.
Noise Levels
Table 3.13-5 shows the measured noise levels in the South Carlsbad North receiver site area. From
this data, it may be assumed that nighttime noise levels would be 52-62 dBA at the north end of the
residential area, and 50-51 dBA Leq at the south end of the area. The large range for noise levels at
the north end reflects the variability in traffic noise, which is the dominant source.
