In late 2018, the Construction Authority received proposals from four highly qualified design-build teams competing to build the Glendora to Montclair project. Through that process, the agency learned that the project would cost hundreds of millions of dollars more than what was already secured. As a result, the overall estimated budget for the project increased to $2.1 billion. Due to the funding shortfall, the project is currently undergoing an environmental review (see Planning) to evaluate the environmental impacts of possibly phasing the construction and operation of the Glendora to Montclair project. This in turn would allow the Construction Authority flexibility to build as far as possible with the available funding.
In December 2018, the LA Metro Board unanimously reaffirmed the agency’s commitment to completing the Foothill Gold Line from Glendora to Claremont (LA County portion) as a first priority project and to identify funding sources and approaches to fill the estimated $570 million funding gap identified by the Construction Authority through the currently on-going procurement. Then in January 2019, the Metro board agreed to ensure sufficient funding so the base project within the design-build contract can include the Pomona Station, reducing the total shortfall by $230 million.
The majority of the funds needed for the Los Angeles County portion of the project (Glendora to Claremont) will come from the Los Angeles County‘s Measure M half-cent sales tax, approved by LA County voters in November 2016, along with nearly $100 million of residual funds from the Measure R half-cent sales tax not used to complete the Pasadena to Azusa segment. Additionally, in April 2018, the project received a nearly $300 million grant from SB1, through the State of California’s Transit and Intercity Rail Capital Program to be used in both Los Angeles and San Bernardino Counties. The Construction Authority is working with the San Bernardino County Transportation Authority to finalize appropriation of funds to extend the line to Montclair (in San Bernardino County).
