Home My WebLink AboutMINUTES - 10012013 - D.2RECOMMENDATION(S): ACCEPT the Draft TriLink Feasibility Study Report and REQUEST comments from the Board of Supervisors for the final report, as recommended by Supervisor Piepho. FISCAL IMPACT: No fiscal impact. BACKGROUND: TriLink (State Route 239) is a potential new high quality transportation facility that would connect State Route 4 near Brentwood to the Interstate 580/205 corridor near Tracy. Over the past 18 months, multiple local agencies, together with environmental and business advocates, have collaborated to study the feasibility of constructing the TriLink facilities. This work has culminated in a draft report which is now available for public review. The purpose of this presentation is to summarize the key findings for the Contra Costa County Board of Supervisors and to solicit comment. See attached presentation materials on the Draft TriLink Feasibility Study. CHILDREN'S IMPACT STATEMENT: Not Applicable.

What did we do? Coordinate with habitat conservation initiatives, including East Contra Costa HCP/NCCP, EACCS, and SJMSCP. Segment Costs Airport Connector $30 - 50 million South Link $80 - 120 million North Link $70 - 100 million I-580 Link $450 - 500 million Transit Varies by type Examined Implementation Scenarios – Preliminary Cost Estimates What did we do? 12 Examined Implementation Scenarios Evaluated possible options for organizational structure, including: ¾Cooperative arrangements between existing authorities ¾Joint Powers Authority (JPA) ¾Memorandum of Understanding (MOU) Compared project delivery methods, including: ¾Traditional publicly-funded approach ¾Innovative financing strategies (public-private partnerships, CTFA bonds, tolling) ¾Alternative delivery methods What did we do? Examined Implementation Scenarios – Available Source Funding Local Funds ($158.4 Billion) 65% State Funds ($53.1 Billion) 22% Federal Funds ($30.9 Billion) 13% Identified Projects TriLink would be an expansion project estimated at $630 – $770 million 2011 – 2020 : $ 242.2 B What did we do? 13 Transportation impact fee program Measure J reauthorization Tolling, user-fees and private financing Funding initiatives (new) What did we do? Examined Implementation Scenarios – Potential Supplementary Sources Engaged Stakeholders Engaged a wide range of stakeholders ¾Public officials from communities in the study area ¾Environmental and business advocates ¾Technical staff from State and local agencies Stakeholders reviewed TriLink traffic and job/housing projections Stakeholders contributed input that informed development of potential routes What did we do? 14 Involved the General Public Feasibility study involved a robust public outreach process Public open house meetings in Brentwood, Tracy, and Mountain House Online “virtual workshop” targeting people unable to attend in person Print and online in the Contra Costa Times, the Tracy Press, and other local media TriLink website: www.trilink239.org What did we do? What did we find? Improve Connectivity and Relieve Congestion Support Local Job Growth Enhance Goods Movement Improve Roadway Safety and Emergency Access Reduce VMT and GHG Emissions 15 Improve Connectivity and Relieve Congestion Without TriLink, peak hour traffic volumes are forecasted to exceed current roadway capacity TriLink would divert traffic from existing roadways and ease congestion What did we find? Support Local Job Growth Communities in east Contra Costa and west San Joaquin counties have planned for job growth There are opportunities in the manufacturing, wholesale, and transportation sectors What did we find? These industries rely heavily on transportation infrastructure TriLink would provide transportation connections needed to make job growth possible 16 Enhance Goods Movement TriLink would be an effective alternative for trips to east Contra Costa County and the northeast portion of the Bay Area Today Byron Highway, Vasco Road, and SR-4 carry higher than normal volumes of truck traffic Truck transport of agricultural produce and consumer goods will increase as Bay Area population grows TriLink improvements would offer significant time savings – 16 minutes on an AM peak hour trip from Tracy to Martinez What did we find? Route: I-580/I-680 I-580 Link/SR-4 Miles 46 43 AM Peak Minutes 82 66 Improve Roadway Safety Sharp curves, narrow lanes, steep grades, lack of passing options, and high traffic volumes create safety concerns on study area roadways TriLink will improve safety with ¾Left-turn bays to provide a refuge for turning vehicles ¾Medians to provide separation between the opposing lanes of traffic ¾Standard shoulder widths providing a buffer from roadside obstacles ¾Two travel lanes in each direction ¾Dedicated facilities for pedestrians and cyclists. What did we find? 17 Improve Emergency Access Mountain House, Knightsen, Discovery Bay, Oakley, and Antioch are all in flood-prone areas TriLink could serve as an emergency evacuation route in the event of a natural disaster TriLink would also be a route into the area for response and recovery assistance. What did we find? Reduce VMT and GHG Emissions Overall VMT reductions of 3.4% Daily VMT decreases by ~ 4 million miles Annual CO2 decreases by ~ 400,000 metric tons Annual fuel savings of over 40 million gallons (over $160 million/year) Annual vehicle hours of delay (VHD) decreases by 57% VMT and GHG modeling indicate that a ‘2040 with TriLink Scenario’ would result in: What did we find? 18 Where are we going?
