Thompson, Public Works Director ATTACHMENTS: Specification to be available at City coUncil meeting RECOMMENDATI~.~~ Authorize Staff to solicit bids for Contract 02,18 FINANCIAL STATEMENT: The construction budget for this project is $132,300, of which $22,400 is reimbursable by a grant from the California Energy Commission. An additional $3,500 is budgeted in the Signal and Lighting Operating Budget to provide "countdown" type pedestrian signals at one intersection. DESCRIPTION: At the October 1st meeting, the City Council approved an agreement with the California Energy Commission regarding the grant funds for the traffic signal battery backup systems (BBS) project. Traffic signal battery backups are a safety feature proposed for eight of the City's more heavily traveled intersections. These units will allow the intersections to continue to operate for approximately two hours in the event of a poWer failUre. The eight intersections proposed to receive BBS units at this time are: Dublin Boulevard/San Ramon Road Dublin Boulevard/Regional Street Dublin Boulevard/Village Parkway Dublin Boulevard/Dougherty Road Hacienda Drive/Hacienda Crossings Dublin Boulevard/Tassajara Road Amador Valley Boulevard/San Ramon Road Amador Valley Boulevard/Village Parkway COPIES TO: ITEM NO. g:kmiscproj\bbs\agstauth The existing BBS at Dublin Boulevard/Hacienda Drive currently operates in flashing red mode and is proposed to be converted to full operation. The project further includes conversion of all yellow indications and the "walk" portion of pedestrian signals at these intersections to LED (light emitting diode), as well as provision of LED "bulbs" for the "programmed visibility" or "PV" signal heads which are intended to be seen only from specific lanes. Staff is also including the "countdown" type of pedestrian signal at the Dublin Boulevard/Village Parkway intersection. This type of pedestrian signal displays the number of seconds remaining to cross the street. This particular item is budgeted in the Signal and Lighting Operating Budget as a test, and if successful, may be proposed for other locations in the future. Staff recommends that the City Council authorize solicitation of bids for Contract 02-18, Traffic Signal Battery Backup Systems.
