3.13 Noise
The proposed receiver site would extend from A Street to D Street in the city of Encinitas. The
Moonlight Beach recreation area and parking lot are east of the central part of the site. Sensitive
noise receptors include single and multi-family residences that are adjacent to the beach at the north
end. The east sides of these homes face 5th Street. The southernmost house is nominally at beach
level, with a porch adjacent to the receiver site. There is rip-rap protection approximately 10 feet
high and 8 feet deep at these houses. At the south end of the fill area, there is a day use park on a
bluff approximately 20 feet above the beach, and residences to the east of the park, on the east side of
Moonlight Lane.
Noise Levels
Table 3.13-8 shows the measured noise levels near the receptors north and south of the beach. Noise
levels were measured in early morning without other noise sources. Nighttime noise levels at the
homes close to the beach are estimated at 67-68 dBA.
