I hate spell check. I am so sorry. This is the copy of the presentation with the typo corrected. Of course
the typo was on the last page that would be on the screen longer.

Tania and Cheri, this is the presentation I already sent to you for Judy Hovjacky for April
12 Planning Commission meeting. If you do this in screen show mode, you can launch
the video on the last page. This is for presentation 7.
Please let me know if this is the way you want to do this. Again, you must tolerate an ad
for 5 seconds and then you can skip it.
Thank you very much.

Noise Impacts at Coral
Mountain

EIR States there will be no adverse noise
impact
• The noise engineer explained that based on Federal Highway
Administration guidance and studies, noise bouncing off a hard
surface can cause noise increases of no more than 1-2 dBA, which is
not perceptible to the human ear. Given the distance between the
Wave Basin and Coral Mountain (approximately 650 feet), the soft
surfaces over that distance that absorb sound, and the maximum,
worst -case noise levels generated at the Wave Basin (75.7 dBA), the
Wave Basin will not cause significant noise levels or noise impacts at
Coral Mountain or in the surrounding communities.

shows 375.1 feet not 650 feet, plus the wave mechanism is

Two Important Noise Measurements
• The dBA unit A -weighted sound level does not measure low
frequencies. In this setting, the meter primarily measures in the 500
to 10,000 Hz range.
• The dBC unit C-weighted sound level does not discriminate against
low frequencies and measures uniformly over the frequency range of
30 to 10,000 Hz. This weighting scale is useful for monitoring sources
such as engines and machinery. dBC frequencies can travel further
and are harder to mitigate.

Sounds from Lemoore — especially listen for the
humming — this is what everyone will hear 7AM to
1OPM or longer, 365 days a year. And it is right next
to Coral Mountain so it will echo.
