APPROVAL OF THE TUSTIN AUTO CENTER LOUDSPEAKER CRITERIA
RECOI~ENDED ACTION:
Pleasure of the Council.
BACKGROUND:
This item was appealed to the City Council and first heard at the June 16, 1986
meeting. At that time, the local residents presented their own noise study and
discussion ensued regarding the use of a loudspeaker system. The item was
continued by the Council to allow the citizens and the Company to meet and
discuss the new noise study and the overall loudspeaker system criteria.
DISCUSSION:
Representatives from The Irvine Company and the local citizens have met to
discuss this issue; in addition, a member of Community Development staff was
present at this meeting. The noise consultant {Marshall Long, Assoc.) reviewed
the citizens' noise study.
According to the noise consultant, the citizen noise study was valid, but
lacking information, was incorrect in several key areas that would skew the
noise data. Those areas included:
1. The study assumed a speaker noise level of 83 dba, instead of the mandatory
75 dba limit.
The study assumed all 36 speakers would be used at once; the consultant
used the 16 speakers nearest the residential units, with the remaining
speakers creating no appreciable effect.
e
The study stacked all twelve dealers at one location (McLean site), and did
not take into account that dealers located further away would have a noise
drop-off from a combination of distances and obstructions.

Taking these items together, the overall sum of noise reduction from the ctttzen
study would be 22 dba. This puts the noise impact to adjoining residents along
Jamboree at approximately 35.2 dba to 46.3 dba.
Regardless of the amount of "technical fog" generated as a result of numerous
studies on either side, the attempt of the meeting was 'co understand the basic
criteria and if possible, improve on lt. After a three hour discussion, it is
hoped that the local citizens understand that the criteria that was generated by
the consultant, amended and recommended by staff, and approved by the Planning
Commission, represents a more restrictive set of regulations than the current
City's noise ordinance. That the tntent of the c~tteria is to authorize a
loudspeaker system that is used at times when it will not impact or disturb the
residents of the City of Tustin. Additionally, from the Company's standpoint,
it is in their own interest to avoid any potential impacts along Jamboree since
they own the housing units adjacent to the McLean dealership.
One additional criteria that came out 'of the meeting was restricting the use of
loudspeakers on holidays. ~Staff supports this addition, and encourages the
Council to add this criteria.~ + ~'
No loudspeakers can be used on is determined to
be the official list of holidays the City of Tustin recognizes.
A summary of the approved Planning Commission criteria includes:
1. Hours and days of operation
8:00 a.m. to 6:00 p.m., Monday through Friday.
2. A volume level no higher than 75 dba for outdoor speakers.
3. Dealers must have a combination of pagers and loudspeakers.
4. Dealers must use a "zone" loudspeaker system.
5. Whenever possible, loudspeakers must be placed in service buildings.
6. Prior to installation, systems require a review and approval of Community
Development.
7. Prior to actual use, system will

APPROVAL OF THE TUSTIN AUTO CENTER LOUDSPEAKER CRITERIA
REC01~ENDED ACTION:
Pleasure of the Council.
SUMMARY:
On April 28, 1986, the Irvfne Company presented the Tustin Auto Center
Paging Impacts Study to the Planning Commission. At this time, the
Commission requested that the item be noticed in the Tustin News and that
certain concerned residents be notified through the mail.
On May 27, t986, a public hearing was conducted to consider the Loudspeaker
Criteria. Numerous revisions were made to the original request and public
input was given. Staff recommended that the amended criteria be adopted
and the Commission by a vote of two ayes to one noe, adopted Resolution
No. 2334 approving the amended criteria {attached). At the June~2nd
meeting of the City Council, this item was appealed by the Council for
further study.
As a part of this report, an acoustical engineer will present a computer
analysis of the loudspeaker impacts.
ANALYSIS AND CONCLUSIONS:
The original Loudspeaker Criteria for the Auto Center was presented to the
Planning Commission in July 1985. This criteria was not adopted by the
Commission due to a lack of information regarding the use of handheld
paging systems. The Irvine Company prepared the attached Paging System
Study and this was presented to the Commission on April 28, 1986. Staff
recommended the "Pleasure of the Commission" and to direct preparation of
an appropriate Resolution.

The Commission requested that this item be advertised in the Tusttn News
and that nottces be mafled to interested citizens. On May 27, 1986, staff
presented Resolution No. 2334 to the Commlssion. This Resolution contained
numerous revisions to the orfgtnal criteria as outlined in the attached
staff report dated May 27, 1986.'
The publtc hearing was conducted and numerous citizens spoke on the item.
Further revisions were made to' the Resolution of approval and 1ts ftnal
adopted form is attached. The Planning Commission followed staff's
recommendation and confirmed that the revised Loudspeaker Crtterta was
appropriate for adoption and approved the criteria by adoption of
Resolution No. 2334.
On June 2, 1986, during the City Council meettng, further concerns were
raised regarding the Planning Commission's adoption of .this crtterla. The
Ctty Council appealed this Item for further study.. Staff has mailed
notices to the same citizens who were previously notified. This list is
attached in the May 27, 1986, staff report to the Planntng Commission.
As part of thls hearing, the Irvlne. Company will present'a computer
analysis of the loudspeaker tmpacts. Attached is a.copy of the Pagtng
Systems Study which includes all pertinent information re:gardfng this
issue.

Exhibit "A"
SOUND SYSTE~ STANDARDS
Any sound system 1nstellation within the Tustfn Auto Center shall conform
to the following standards:
Se
All dealers are encouraged to use a hand held pagtng system. In the
event that use of outdoor loudspeakers ts necessary, no dealer wtll be
authorized for an exclusive-use of outdoor loudspeakers, a combination
of loudspeakers and hand held paging may be authorized upon review of
the system by the City of Tusttn.
In the event that loudspeakers must be used, a dealer's lot shall be
covered by multiple zones so that enunciation through a loudspeaker
occurs on a controlled area of the parcel rather than across the entire
lot.
Should a dealer choose to use some outdoor loudspeakers, the use of
this system is limited to operation between the hours of 8:00 a.m. to
6:00 p.m., Monday through Friday. Should a dealer wish to either
expand these hours or days of use, approval of the Planning Commission
must be obtained. In no event shall any use of outdoor speakers be
authorized for operation on Sundays.
All loudspeakers shall be mounted at a 75 degree angle facing the
ground to avoid voice travel. All loudspeakers mounted on perimeter
walls shall be located at least two (2) feet below the ~op of the wall.
All loudspeakers shall be directed toward the interior of each lot.
Each speaker layout system shall .be subject to review and approval by
the Community Development Oepartment.
Whenever possible, loudspeakers shall be placed within service
buildings'rather than on the outside of the structure.
Whenever possible, loudspeakers shall be placed in such a manner to
prevent "bouncing" of sound off a nearby building.
All outdoor loudspeakers shall be set at a volume level no louder than
75 dB(A).
Prior to installation of a loudspeaker system, each dealer shall obtain
any necessary building permit(s) from the City of Tustin. Upon
installation of the system and as a condition of final approval of work
authorized by these permit(s), sound readings shall be taken of that
dealership's loudspeaker impacts on adjacent land uses, and the speaker
volumes shall be adjusted so that they do not exceed the impacts
stipulated below. Further, the speaker installer or sound engineer
shall advise the City in writing that the loudspeaker volume adjustment
has been mechanically or electrically locked off at 75 dB(A) or lower,
to preclude arbitrari.ly increasing the volumes at a later date.

ITEM ~ 7
RECOI~E#DEDACTIO#:
That the Planning Commission approve the revised Loudspeaker Criteria for- the
Tustln Auto Center by the adoption of Resolution No. 2334.
$~WdlARY:
On April 28, 1986, the Planntng Commission revtewed The Tusttn Auto Center
Loudspeaker Crl'terta. At thts time, the ]rvtne Company presented a computer
analysts and paging system study for the Commission's consideration.
Staff had r~commended 'chat the Commission dtrect staff to prepare an acceptable
resolution of approval for the Criteria. However, the Commission had requested
that this item be noticed for public hearing In the Tusttn News and also that
nottces be sent to interested parties. A list of the public nottce circulation
has been attached for your review.
At this time, the Loudspeaker Criteria ts presented as' a public hearing.
Another presentation will be made by the Irvtne Company and the sound
analyst, David Dubbtnk Associates. Both public and Commission comments will be
taken to ensure proper coverage of all issues involved in this matter.
As requested by the Commission, staff has prepared Resolution No. 2334. This
resolution includes numerous revisions to the previously presented criteria as
outlined below. The proposed revisions were presented to The Irvtne Company
prior to this hearing.
ANALYSIS AND CONCLUSION:
As covered in Exhibit No. 1, the revisions to the Loudspeaker Criteria are
found in the sound system standards section of the previously submitted cri tera
(Exhibit No. 2). The revisions to the sound system standards include:
P1 ann1 ng Commission Report
May 27, 1986
· Page 13~o
Dealers are encouraged to use' either a hand held paging system or a
combination of loudspeakers and hand held pagers. Exclusive use of
loudspeakers is prohibited.
The hours of operation of the loudspeakers have been 11mired to 8:00
a.m. to 6:00 p.m., Monday through Friday. An expansion of the days or
hours of operation must be approved by the Planning Commission. In no
event shall any loudspeaker system be used on Sundays.
All loudspeakers shall be mounted at a 75% angle facing the ground to
avoid noise travel.
e
No speakers shall face Auto Center Drive unless blocked by another
building.
All loudspeakers shall be set at 75 db(A) as opposed to the previously
proposed 80 db(A) level.
The City shall inspect all louUspeaker systems for compliance to all
Sound'System Standards and to ensure that the volume level is
"locked-off".
The City may make random periodic inspections of all loudspeaker
systems used in the Auto Center. Should any violations be found, the
use of loudspeakers shall be discontinued until all standards have been
met.
Staff contends that these revisions will reduce the overall impact of the
loudspeaker systems on the existing and future Tustin residents. As revised,
the Loudspeaker Criteria, will provide for an acceptable mix of pagers and
loudspeakers considered appropriate for the Tustin Auto Center.

Maximum sound levels at adjacent property lines shall be:
35 dB(A) to any residence along Browning Avenue;
55 dB(A) to the outside of the soundwall along the property
line of any residence abutting Jamboree Road; and
65 dB(A) to any adjacent commercial uses which occur outside
of the AUto Center. (This level is limited to five (S)
minutes in any hour, overall a maximum of 60 dBA is allowed).
TUSTIN AUTO CENTER
LOUDSPEAKER CRITERIA
In light of the City's and the Developer's mutual concern to protect nearby
residents and future land users from undue noise intrusion by the Tustin
Auto Center, the following Criteria has been developed for the use of any
amplification system(s) within the project. The Criteria is based on an
acoustical analysis prepared by Marshall Long S Associates for the McLean
Cadillac paging system, which will be the dealership located nearest to any
existing or future residences. A copy of this report is attached for reference,
and is summarized as follows:
Per Tustin Noise Ordinance adopted July :21, 1980, noise impacts
to any residential area shall not exceed 55 dB(A) from the hour's
of-7-=.00 =..~m. - 10:00-p,m. Any speech or simple tone noise shall
require a further noise level reduction of 5 dB(A). Conversely,
the allowable noise level shall be increased by 10 dB(A) for any
sound impacts which occur 5 minutes or less per hour, as is typical
for auto dealers' paging systems. Cumulatively, these standards
allow a maximum noise impact from a typically operated amplification
system of 60 dB(A).
2. The analysis is based on the following conditions and is thereby
considered "worst-case":
ae
No allowance has been made for future background traffic
noise along Jamboree Road, which will eventually reduce
impacts of noise generated within the Auto Center.
No allowance has been made for any sound *attenuation measures
which will be taken by the future residential project to be built
between Browning and Jamboree Roads. Due to major noise
impacts to that project from traffic on the freeway, on Jamboree
Road, and on Laguna Road, the residential development will be
enclosed by a sound wall and will include other noise attenuation
measures which cumulatively serve to reduce noise levels by at
least 7 dB(A) to the nearest backyard along Jamboree Road and
at least 25 dB(A) inside the nearest unit. These noise reductions
are not taken into account in the noise limits established by this
Criteria.
The noise analysis assumes that loudspeakers on the project's
perimeter are located 2~ below the perimeter wall, are directed
away from the perimeter wall, and are set at 80 dR(A).
Computer analysis establishes that in light of the above conditions,
worst-case impact of loudspeakers placed along the Jamboree Road
dealer's property line will be as follows:
35 dB(A) to the nearest Browning Avenue resident prior to
the construction of any housing units within the future resi-
dential project which separates Browning Avenue from the Auto
Center. According to the "Typical Noise Levels (A-Weighted
Scale)" exhibit which was prepared under the project's EIR in
1984, 35 dB(A) is equivalent to the sounds, to be heard inside
a library or during a quiet rural night. Noise measurements
which were taken on September 17, 1984 by John Hillard S
Associates of Tustin indicated' that at three points measured
along Browning Avenue between Bryan Avenue and Laguna
Road, the present daytime sound levels range from the Iow -
high 60 dB(A) levels. Consequently, 35 dB(A) impacts from
the Auto Center will be perceived as insignificant.
0
60 dB(A) maximum impact to the nearest residential property
line along Jamboree Road prior to the construction of the
residential sound wall or other attenuation measures. By law
the noise impacts to this property cannot exceed 65 CNEL,
which is a 24-hour averaged noise measurement. The Auto
Center's maximum impa~:t of 60 dB(A) occurring for five minutes
per hour between 7:00 a.m. and 10;00 p.m. is the equivalent
of a CNEL level of 48.6 dB, and is consequently well below
allowable limits and below the traffic impacts created along
Jamboree Road or the freeway.
Table #10 of'the Marshall Long analysis represents specific
test data under which a paging system set at 80 dB(A) was
measured at the nearest residential property line at levels
which ranged between 49.3 and 54.6 dB. This further confirms
that the 60 dB(A) impact would be both a maximum and a worst-
case condition.
SOUND SYSTEM STANDARDS
In light of the above data, any sound system installation within the Tustin
Auto Center shall conform to the following standards:
1. Whenever possible, dealers are encouraged to use hand-held paging
devices rather than loudspeaker systems for maximum sound attenuation.
In the event that loudspeakers must be used, a dealer's lot shall
be covered by multiple zones so that enunciation through a loud-
speaker occurs on a controlled area of the parcel rather than across
the entire lot.
Loudspeakers may not be used prior to 8:00 a.m. or after 7:00 p.m.
If, at any time, a dealer shall deem it critical to his/her business
operation to use any loudspeakers at an earlier or later hour, specific
Planning Commission approval must first be obtained.
#. Loudspeakers along the perimeter of the project or that are not
directly shielded by a building shall be placed at least 2' below
the top of the perimeter wall which surrounds that dealer's property.
5. Ail loudspeakers shall be directed toward the interior of the project
and away from the perimeter property line(s}.
Whenever possible, loudspeakers shall be placed within service
buildings rather than on the outside of the structure.
Whenever possible, loudspeakers shall be placed in such a manner
to prevent "bouncing" of sound off of a nearby building.
Prior to installation of a loudspeaker system, each dealer shall obtain
any necessary building permit(s) from the City of Tustin. Upon
installation of the system and as a condition of final approval of work
authorized by these permit(s}, sound readings shall be taken of that
dealership's loudspeaker impacts on adjacent land uses, and the speake~
volumes shall be adjusted so that they do not exceed the impacts
stipulated below. Further,' the speaker installer or sound engineer'
shall advise the City in writing that the loudspeaker volume adjustment
has been mechanically or electrically locked off' to preclude arbitrarily
increasing the volumes at a later date.
Maximum sound levels at adjacent property lines shall be:
a. 35 dB[A] to any residence along Browning Avenue.
b. 55 dB(A) to the outside of the soundwail along the
property line of any residence abutting Jamboree Rd.
c. 65 dB(A) to any adjacent commercial Uses which occur
outside of the Auto Center.
