OCTA issued a call for projects through the Regional Traffic Signal Synchronization Program to coordinate traffic signals across jurisdictional boundaries in the county.  Two corridors, Garden Grove Boulevard and Katella Avenue, were identified as heavily traveled corridors that would benefit from traffic signal coordination.

The proposed Garden Grove Boulevard project spans approximately 8.6 miles and includes 34 traffic signals.  It would begin at Valley View Street in the City of Westminster and terminate at Bristol Street in the City of Santa Ana (see attached map – Exhibit A).  The Garden Grove Boulevard project cost is estimated at $2,514,688.  The City currently has jurisdiction of 20 traffic signals on Garden Grove Boulevard and the project subtotal for the City of Garden Grove is $2,274,762.  The local match is $454,952.  The project will include the development and implementation of signal timing, traffic signal equipment upgrades, communications upgrades, and two years of traffic signal timing maintenance. The project is anticipated to begin September 2018.

The proposed Katella Avenue project spans approximately 19.6 miles and includes 73 traffic signals.  It would begin at the I-605 in the City of Los Alamitos and terminate at Jamboree Street in the City of Orange (see attached map – Exhibit B).  The Katella Avenue project cost is estimated at $4,884,134.  The City currently has jurisdiction of two traffic signals on Katella Avenue and the project subtotal for the City of Garden Grove is $50,100.  The local match is $10,020.  The project will include the development and implementation of signal timing, traffic signal equipment upgrades, and 2 years of traffic signal timing maintenance.  The project is anticipated to begin September 2018.

There is no impact to the General Fund.  The City of Garden Grove’s financial responsibility towards the two projects is estimated at $464,972.  Public Works will be funding the projects through Traffic Mitigation Fees and Measure M2 Local Fair Share.

It is recommended that the City Council:

• Adopt the attached Resolution approving the submittal of the Garden Grove Boulevard and Katella Street Synchronization Improvement Projects to the Orange County Transportation Authority for funding under the CTFP.
