Purpose and Recommended Action
Recommendation
This is a request for City Council to authorize the City Manager to enter into Amendment No. 1 to the Intergovernmental Agreement (IGA) with Arizona Department of Transportation (ADOT) for the 67th Avenue from Glendale Avenue to Cholla Street Intelligent Transportation Systems (ITS) Enhancements Project. This Amendment will increase the amount of federal funding from $904,164 to $971,144, and will reduce the city’s funding amount from $187,500 to $88,702. This will change the total estimated construction cost of the project from $1,091,664 to $1,059,846. All other provisions of the original agreement shall remain in place.
Background
The city has made a significant investment in deployment of ITS infrastructure along arterial and collector streets to enhance the management of traffic. These improvements enable Transportation staff to remotely monitor traffic and adjust signal timing based on current traffic patterns, or in response to resident requests. Additionally, drivers can receive real-time information on event traffic conditions and travel times via dynamic message signs (DMS).
The city’s ITS infrastructure is currently comprised of over 100 miles of fiber optic cable that provides communication to 160 of the city’s 198 traffic signals, 115 closed-circuit television (CCTV) cameras, and 14 DMS. Future infrastructure expansions include 51st Avenue, Olive Avenue, Northern Avenue, and Maryland Avenue.
Analysis
This project to install ITS infrastructure along 67th Avenue, from Glendale Avenue to Cholla Street, was identified in the city’s ITS Strategic Plan and will close a gap in the traffic management system. Once completed, all signals on 59th and 67th Avenues, north of Glendale Avenue, will be connected to the central signal system. This project is identified in the Maricopa Association of Governments’ Transportation Improvement Program, and federal funds for construction have been secured for federal FY 2016. The city applied for and was granted additional 2016 federal funding that reduced the city’s local match.
Previous Related Council Action
On October 8, 2013, Council approved an IGA with ADOT for project administration, design review, construction bidding and construction administration of ITS infrastructure along 67th Avenue, between Glendale Avenue and Cholla Street.
On December 11, 2012, Council approved a Professional Services Agreement with Stanley Consultants, Inc., for the design of ITS infrastructure on 67th Avenue, between Glendale Avenue and Cholla Street.
Community Benefit/Public Involvement
Technology enhancements will continue to provide efficient traffic management for the traveling public, and this design project will address improvements to the ITS infrastructure along one of Glendale’s most critical north-south corridors.
Budget and Financial Impacts
The total estimated construction cost of the project is $1,059,846, including a $30,000 ADOT fee to administer the project on behalf of the city. Of the total anticipated cost, $971,144 is available through the federal Congestion Mitigation and Air Quality program. The required city match of $58,702 and the $30,000 ADOT fee are available in the GO Transportation Program Smart Traffic Signals account. On October 8, 2013, Council approved a local match of $187,500; this Amendment will reduce that amount to $88,702. Additional operating and maintenance costs will be absorbed by the GO Program ITS operating budget.
While staff does not anticipate additional project costs, should this project exceed the estimate outlined in the IGA, the City will be responsible for the additional costs. Since the funds listed in the IGA are estimates, staff requests flexibility in spending up to 10 percent of the total project cost in additional funds for construction cost overruns.
