On January 28 Quentin Kopp sent a letter to Senator Dianne Feinstein's office listing potential HSR construction projects that "can currently be commenced". Included grade crossings in the La Mirada area of Southern California that Metrolink has planned and that HSR would use, although as Kopp notes, "a certain amount of additional engineering will be required to accommodate our project." Also listed is work at San Bruno, ROW acquisition and site prep in the Central Valley, and Caltrain electrification. You can read the letter here (PDF), and the list of proposed projects is below:
LA-Anaheim grade separations:
Passons Blvd/Serapis St: $43.4 million
Pioneer Blvd: $45 million
Norwalk Blvd: $150 million
Lakeland Rd: $40 million
Rosecrans Ave: $150 million
Valley View Ave: $72 million
San Bruno projects: $250-$300 million
Includes separations at San Bruno Ave, San Mateo Ave, and Angus Street; Pedestrian crossings at Euclid and Sylvan Avenues, and an elevated station
By September 2011 the Authority will have underway the right-of-way purchase and construction grading of a heavy maintenance facility in the Central Valley and two storage "layover" facilities, one in the Bay Area and one in the Los Angeles Basin at an estimated cost of $200 million.
Additionally, the Caltrain Electrification Project is scheduled to commence by fall 2011. That includes design and procurement for the electrification of the system from San Jose to San Francisco, train controls, and commuter vehicles at an estimated cost of $1.5 billion.
Others in comments on recent posts have noted that San Jose Diridon Station is in line for some of the HSR stimulus funds, but that wasn't specifically included in this one letter.
It's worth noting that this letter was written before it was known that the final stimulus figure for HSR would be $8 billion, or that the deadline on spending that money would actually be September 2012. That may change things somewhat, but at least the letter gives us an idea of what we might see the stimulus pay for in terms of California high speed rail.
