Disaster Preparedness Managers ask Community Hearing on Early
Warning Siren System
November 15, 2005
President Peskin and members of the Disaster Council,
Thank you for your attention to San Francisco's efforts to create
the nation's most innovative Early Warning Siren System. As you
know, the system has a number of unique functions, including the
ability to broadcast different messages in different neighborhoods,
to broadcast in different languages, and to broadcast from remote
locations with wireless devices.
During the initial implementation phase of the siren project,
technical staff of the Department of Telecommunication and Information
Services (DTIS) discovered mechanical shortcomings in the sirens
while performing quality assurance tests. DTIS then secured an
independent auditory expert to verify and detail technical constraints
of the hardware. DTIS recently received the report from this expert
and has apprised the contractor that provided the siren hardware
of the need to repair or replace this hardware. Additionally during
this process, several repairs were made to the existing system.
It is important to note that at no time has the siren system been
non-functional while these refinements and repairs have been made.
Additionally, DTIS staff has built redundancy into the siren
system that has allowed it to function without interruption, as
verified by the fact that weekly tests continued to occur every
Tuesday at noon during this initial implementation phase.
We believe that a public hearing to share information with our
residents is the best way to ensure that there are no misconceptions
about the city's siren system. It is important that local residents
are made aware of this innovative project, as well as refinements
and modifications that are being made currently and additional
future actions to test and refine the system. Given the recent
anxiety in our country around tsunamis and floods, we would like
to schedule the hearing in the Western part of our city, specifically
in the Sunset neighborhood.
We respectfully request that you partner with us to hold this
public hearing in the community to ensure that our citizens are
kept informed of this important disaster preparedness project.
