SUBJECT: TRAFFIC SIGNAL BATTERY BACKUP PROJECT — SPECIFICATION NO.
90079
CAO RECOMMENDATION
1) Approve specifications for "Traffic Signal Battery Backup Systems, Specification No.
90079."
2) Authorize staff to solicit bid for"Traffic Signal Battery Backup Systems, Specification No.
90079"
3) Allocate$4,300 from the CIP Reserve account for the remaining cost of the BBS projects.
4) Authorize the CAO to award a contract if the lowest responsible bidder is within engineer's
estimate.
DISCUSSION
On July 2, 2002, the Council approved a resolution authorizing staff to apply to the California
Energy Commission (CEC) for grant funding for battery backup system (BBS) projects. As
Council will remember, due to our use of light emitting diode (LED) lights at traffic signals, a BBS
that keeps signals operating during power outages is now feasible: Staff applied for, and will
receive funding for ten locations that met CEC criteria for the grant funds:
1) Madonna/Los Osos Valley
2) Foothill/Chorro/Broad
3) California/Foothill
4) Madonna/Oceanaire
5) Marsh/Higuera
6) Tank Farm/Higuera
7) Royal/Los Osos Valley
8) Madonna/Dalidio
9) Laguna/Los Osos Valley
10)Madonna/El Mercado
After receiving notice of grant award, staff began preparation of installation specifications. These
are now complete and ready to advertise for bidders.

FISCAL IMPACT
On July 2, 2002,the Council approved the following budget for the BBS projects:
Amount Source
$25,200 CEC Grant
$14,800 Required Match—Existing Battery Backup and
ticom Grant
$1,200 Existing Battery Backup and O ticom Grant
$40,000 Total
However,the estimated installation cost and budget is as follows:
Item Amount
Purchase and Installation of Hardware $43,000
Contingencies .$1,300
Total $44,300
Funding Available $40,000
Deficit $4,300
Funding the Deficit: The City has already appropriated$16,000 of its existing Opticom and Battery
Backup grant received from SLOCOG ($76,000 is currently unencumbered). Staff does not
recommend that the $4,300 be drawn from the existing Opticom and Battery Backup grant account
because this money will be necessary for implementation of recommendations made in the Annual
Traffic Safety Report and the forthcoming Traffic Signal Master Plan. It may also be necessary to
use some of these existing funds for mitigation associated with the Copeland's project. Therefore,
$4,300 of the CIP reserve should be allocated to cover the remaining costs of the purchase and
installation of the battery backup systems.
Staff therefore recommends $4,300 be allocated from the CEP reserve account to complete the
project; thereby taking advantage of the significant grant source (59 percent of the total project
cost).
The City will be reimbursed up to $25,200 by the CEC after installation of the BBS project is
complete.
ALTERNATIVES
1) Do not accept BBS grant funding and terminate the existing contract with the CEC. This
alternative results in the ten recommended traffic signals continuing to operate as they
currently do. If the power goes out,the signals will also go out.
2) Allocate the $4,300 from the existing Opticom and Battery Backup grant funding. This
alternative results in the project moving forward as planned, however it further depletes
