Measure BB Transportation Sales Tax and Alameda Countywide 2014 Transportation Expenditure Plan

On November 4th, 2014 Alameda County Voters approved Measure BB, the Transportation Sales Tax

Measure B, Alameda County’s one-half cent sales tax for transportation was first approved by voters in 1986 and reauthorized in 2000. On November 4, 2014 Alameda County voters reauthorized and augmented this one-half cent the sales tax measure and associated countywide Transportation Expenditure Plan (TEP).  Measure BB will provide nearly $8 billion over 30 years for transportation improvements throughout Alameda County; the sales tax will sunset in 2045.

For the City of Livermore, reauthorization of Measure BB and the new TEP will nearly double the City’s funding to maintain and improve our local transportation system. This will result in new and improved freeway interchanges, better maintained roads and trails, new pedestrian and bicycle facilities, funding to help bring BART to Isabel Avenue in the I-580 median, and will restore and expand bus and train services. Below is a partial list of Livermore and Tri-Valley projects included in the TEP that will receive Measure BB funds.

  • BART extension to Livermore in the I-580 median to Isabel Avenue ($400 million)
  • State Route 84 widening and interchange improvements between Pigeon Pass and I-680 ($130 million)
  • Livermore Local Streets and Roads improvements ($1.74 million annually)
  • Livermore Bike and Pedestrian Projects ($420,000 annually)
  • I-580 improvements including I-580/I-680, I-580/Vasco Road, I-580/Greenville Road, and I-580 Isabel Phase 2 interchanges ($480 million)
  • Major Commute Corridor Projects such as widening Greenville Road, Dublin Boulevard, Dougherty Road, and El Charro Road ($639 million)
  • I-680 northbound carpool/high-occupancy lanes from SR-237 to Alcosta Boulevard ($60 million)
  • Iron Horse Trail bicycle and pedestrian gap closure projects
  • Freight corridor improvements on I-580
  • LAVTA operations and maintenance for Wheels transit service ($1.3 million annually)
  • ACE operations and maintenance ($2.6 million annually)
  • Student transit pass program and other projects to increase access to transit
  • Modernization of BART stations and system maintenance and expansion
Since inception, Measure B funds helped fund the following Tri-Valley projects:
  • I-580/Isabel Interchange
  • BART to Livermore studies
  • New alignment for State Route 84 (SR-84) (now Isabel Avenue) including extension of SR-84 from Stanley Boulevard to Jack London Boulevard, widening of SR-84 from I-580 to Vallecitos Road, and improvements through Pigeon Pass
  • BART extension to Dublin/Pleasanton
  • I-580/I-680 interchange flyover
  • I-580 eastbound auxiliary lane from Santa Rita Road to Isabel Avenue/SR-84
  • Local Streets and Roads, Mass Transit, Bicycle and Pedestrian, and Paratransit Improvements 
Why Measure BB is Proposed

Measure BB and the associated TEP was considered because all of the major projects approved by the voters and funded in the 2000 Measure B are either underway or complete. Measure B funded the top transportation priorities in the County but did not include enough money to fully meet our transportation needs. As our population and related transportation needs continue to grow, more funding is needed to meet these demands. State and Federal funds are not enough to meet local needs, and have become less reliable over time. Local funding mechanisms both increase local control over local dollars and position our County to attract external dollars. Extending Measure BB funds allows for the planning of long-range mobility needs in Livermore, and Alameda County as a whole.

A key feature of the countywide sales tax is that it cannot be used for any purpose other than local transportation needs. It cannot be taken by the state or by any other governmental agency under any circumstance, and over the life of this TEP the funds can only be used for the purposes described in the TEP, or as amended.

The TEP was unanimously approved by each of Alameda County's 14 cities and the Alameda County Transportation Commission. Livermore approved the TEP on March 10, 2014, a link to City Council report can be found here. It was then approved by the Alameda County Board of Supervisors on July 8th to be placed on the ballot November 4, 2014.

Oversight of Measure BB

The TEP is a 30-year plan that includes strict accountability measures to ensure all $8 billion are spent on approved projects. The TEP requires an open and transparent public process to allocate the funds, annual independent audits, and independent watchdog committee made up of people who live in Alameda County, and annual compliance reports distributed to the public that detail costs and how specific performance measures are met.

Fact Sheets about the Transportation Expenditure Plan:

City of Livermore recognized as national leader in creating streets that work for everyone

The City recently received national recognition for its Complete Streets Policy which helps implement the City’s vision to make streets safer and more convenient for everyone who uses them.  Smart Growth America is a national organization that has been reviewing and ranking Complete Street policies annually since 2006. In 2013 more than 80 communities adopted Complete Street policies. Livermore’s policy was ranked 11th and was one of only three California cities ranked in the top 15. Smart Growth America’s report of the Best Complete Streets Policies of 2013 features a cover photo of First street in Downtown Livermore and can be read here:

The national recognition is based on the City of Livermore’s Complete Streets Policy  which the City Council unanimously passed on January 28, 2013. Through this policy, the City of Livermore is committed to creating and maintaining Complete Streets that provide safe, comfortable, and convenient travel through a comprehensive, integrated transportation network that serves all categories of users, including pedestrians, bicyclists, persons with disabilities, motorists, movers of commercial goods, users and operators of public transportation, emergency responders, seniors, children, youth, and families. This policy was developed to provide guidance for residents, decision makers, staff, and various partners to ensure that multimodal elements are incorporated into all transportation improvement projects. Potential improvements that will be considered with these goals include travel lanes that accommodate commercial and transit vehicles, sidewalks, shared use paths, bicycle lanes, bicycle routes, paved shoulders, traffic signals, trails, street trees and landscaping, planting strips, accessible curb ramps, crosswalks, refuge islands, pedestrian signals, signs, street furniture, bicycle parking facilities and lockers, public transportation stops and facilities, transit priority signalization, and other features assisting in the provision of safe travel for all users.
