No Significant Environmental Impacts?

Ordinance No. 2006-09
"The City Council of the City of Escondido, California, DOES HEREBY ORDAIN as follows:
. . .
"SECTION 2. That the City Council has reviewed and considered the Addendum to the Final Environmental Impact Report for the Escondido Research and Technology Center (City Log No. ER-2001-12) and Mitigation Monitoring Report prepared for this project and has determined that all environmental issues associated with the project have been addressed and no significant environmental impacts will result from approving this project."

Has the City Council really reviewed the ERTC EIR Addendum? I quote from the ERTC EIR Addendum, Attachment 4, pages 7-8:

"3.2 Emergency Helicopter Operations Noise Impact
. . .
The maximum instantaneous noise levels would range from approximately 80 to 90 dB at the closest residences located west and northwest of the site. This maximum instantaneous noise level range is similar to a heavy truck at a distance of 50 feet. The maximum instantaneous noise level contours associated with helicopter landings or takeoffs are shown in Figure 5. The maximum instantaneous noise level inside the closest homes would vary depending if the windows are open or closed. If the windows are open, it is anticipated that th maximum sound level inside the closest homes could reach 75 dB. If the windows are closed, the maximum sound level could reach 70 dB. These noise levels could result in sleep disturbance for some of the occupants. Based on the recent helicopter records described in the previous paragraph, approximately four to five nighttime flights per month would be anticipated."

Is being subjected to sleep disturbances several times a month signficant?

The Escondido City Council has declared the following:
Escondido Municipal Code
"Sec. 17-226. General provisions.
(a) The city council of the City of Escondido finds and declares that:
(1) Inadequately controlled noise presents a growing danger to the health and welfare of the residents of the City of Escondido;
(2) The making and creating of disturbing, excessive, offensive or unusually loud noises within the jurisdictional limits of the City of Escondido is a condition which has persisted and the level and frequency of occurrence of such noises continue to increase;
(3) The making, creation or continuance of such excessive noises which are prolonged or unusual in their time, place and use effect and are a detriment to the public health, comfort, convenience, safety, welfare and prosperity of the residents of the City of Escondido;
(4) Every person is entitled to an environment in which the noise is not detrimental to his or her life, health and enjoyment of property; and
(5) The necessity in the public interest for the provisions and prohibitions hereinafter contained and enacted is declared to be a matter of legislative determination and public policy and it is further declared that the provisions and prohibitions hereinafter contained and enacted are in the pursuance of and for the purpose of securing and promoting the public health, comfort, convenience, safety, welfare, prosperity, peace and quiet of the City of Escondido and its inhabitants.
. . .
This decibel (dB) table compares some common sounds and shows how they rank in potential harm to hearing. Note that 70 dB is the point at which noise begins to harm hearing, that 60 dB is the threshold of stress response, and 45 dB disturbs sleep. To the ear, each 10 dB seems twice as loud."
