Metro Board Advances Sepulveda Transit Corridor as C Line South Bay Extension Remains Under Review
The Los Angeles Metro Board meeting addressed progress on two key rail projects: the approved underground Sepulveda Transit Corridor, enhancing regional connectivity, and the debated extension of the Metro C Line into the South Bay, which remains undecided.
The future of Los Angeles transit was the focus of a recent Los Angeles County Metropolitan Transportation Authority (Metro) Board meeting, where directors considered progress on two major rail projects: the Sepulveda Transit Corridor and the long-planned extension of the Metro C Line into the South Bay.
While the meeting resulted in a decisive vote on one project, the other continues to generate debate among Metro officials, local cities, and residents.
Sepulveda Transit Corridor: Underground Heavy Rail Moves Forward
The Metro Board unanimously approved the Locally Preferred Alternative (LPA) for the Sepulveda Transit Corridor, marking a major milestone for a project that has been discussed for decades.
The approved alternative calls for a fully underground heavy rail subway connecting the San Fernando Valley to the Westside, running from the Van Nuys Metrolink Station to the Metro E Line’s Expo/Sepulveda Station. The line would pass beneath the Sepulveda Pass, UCLA, and other high-demand travel areas.
Metro officials emphasized that the underground alignment offers the fastest travel times, highest passenger capacity, and the fewest surface-level impacts when compared with earlier aerial or monorail alternatives. The project is expected to significantly reduce congestion along the 405 Freeway corridor and improve regional connectivity.
With the LPA now selected, the Sepulveda Transit Corridor advances toward final environmental clearance, engineering, and eventual construction — a process that will continue over the coming years.
Metro C Line Extension: South Bay Alignment Debate Continues
The Board also discussed the Metro C Line extension into the South Bay, a project intended to extend light rail service approximately 4.5 miles from the current Redondo Beach station to the Torrance Transit Center.
Metro has released the project’s Final Environmental Impact Report (FEIR), which incorporates years of technical analysis and public input. However, unlike the Sepulveda project, the Board did not take final action to certify the FEIR or formally adopt a locally preferred alignment at this meeting.
Hawthorne Boulevard vs. Metro Right-of-Way
At the center of the C Line discussion is the question of alignment.
Metro staff has identified a “hybrid” alignment using an existing Metro-owned rail right-of-way as the preferred option. This route would largely follow the historic Harbor Subdivision corridor, minimizing new street disruptions while blending at-grade, elevated, and below-grade segments.
Some South Bay cities, however, continue to advocate for a Hawthorne Boulevard alignment, which would place rail tracks within the median of the busy commercial corridor. Supporters argue it offers better street-level access, while Metro has cited higher costs, longer construction timelines, and greater traffic impacts as key concerns.
Metro officials indicated that additional coordination with local jurisdictions and further Board action will be needed before a final decision is made.
What This Means for LA Transit
The contrast between the two projects was clear at the meeting: the Sepulveda Transit Corridor is now firmly on a defined path forward, while the C Line extension remains in a critical decision-making phase.
Together, the projects highlight both the ambition and complexity of expanding transit in Los Angeles County — balancing regional mobility goals, neighborhood impacts, and long-term funding realities.

Where Does Federal Money Go? The Biggest Costs Behind the Budget
Where does federal money go? Part two of our National Debt Explained series examines the biggest expenses in the 2025 budget and how spending connects to government borrowing.
Last Updated on October 13, 2026 by Daily News Staff
The Knowledge | National Debt Explained, Part 2
When discussing debt, ask: Who borrowed the money? That question helps distinguish a family’s finances from the federal budget. Our first episode explained why your credit card balance is separate from the national debt. Now comes the next question: What does the federal government spend money on?
Much of it pays for retirement benefits, health coverage, national defense, public services, and interest on previous borrowing.
Social Security was the largest individual program in fiscal year 2025, costing approximately $1.6 trillion. But combine the major health care programs—including Medicare, Medicaid, and health insurance subsidies—and their spending reached about $1.8 trillion, exceeding Social Security alone. cbo.gov
The figures below cover October 1, 2024, through September 30, 2025.Major expense FY 2025 spending What it supports Social Security About $1.6 trillion Retirement, survivor, and disability benefits Medicare, net $988 billion Health coverage for older adults and certain people with disabilities Net interest $970 billion Cost of servicing publicly held federal debt, after subtracting interest income Discretionary defense $893 billion Military personnel, operations, equipment, and research Medicaid $668 billion Federal contribution toward health coverage and care for eligible people
These are selected expenses, not the entire budget. Medicare spending is shown after premiums and other offsetting receipts. The combined health care total already includes Medicare and Medicaid, so it should not be added to those rows. cbo.gov
The government also supports veterans’ health care, transportation, education, housing assistance, courts, law enforcement, scientific research, disaster response, and environmental protection. Nondefense discretionary spending totaled approximately $980 billion in 2025, covering many of these services. Some funding for these areas falls elsewhere in the budget. cbo.gov
Federal spending falls into three broad groups:
- Mandatory spending: Payments governed by existing eligibility rules and benefit formulas, including Social Security and major health programs.
- Discretionary spending: Funding lawmakers control through appropriations legislation, including most defense spending and many public services.
- Net interest: The expense of servicing publicly held federal debt, minus government interest income. cbo.gov
Interest deserves attention because it pays for borrowing already undertaken. In 2025, net interest exceeded discretionary defense spending. Congressional Budget Office
A program’s cost does not automatically translate into an equal increase in national debt. Taxes and other receipts finance much of federal spending. Social Security and Medicare’s hospital insurance program receive dedicated payroll taxes, while Medicare also collects premiums.
In 2025, federal spending totaled approximately $7 trillion, compared with $5.2 trillion in revenue. The roughly $1.8 trillion shortfall was the deficit, requiring borrowing. Understanding national debt therefore means examining both what government spends and what it collects. cbo.gov

Whose Debt Is the National Debt?
The national debt isn’t Americans’ credit card balances added together. This simple explainer separates federal borrowing from household debt and explains the difference between debt and a deficit.
Last Updated on October 11, 2026 by Daily News Staff
The Knowledge | STM Daily News
When you hear “national debt,” do you picture everyone’s credit card balances added together? The name can create that impression, but the national debt and household debt measure different borrowing.
The U.S. national debt is money the federal government owes. Your personal credit card balance is not included.
Federal debt versus household debt
The Treasury defines national debt as the federal government’s total outstanding borrowing accumulated over the country’s history. Household debt covers borrowing by individuals and families, including mortgages, credit cards, auto loans, and student loans.
|Type of debt |Who borrowed? |Examples |
|————–|————————|————————————————–|
|National debt |Federal government |Outstanding Treasury securities |
|Household debt|Individuals and families|Credit cards, mortgages, auto loans, student loans|
Putting a $500 purchase on your credit card increases your personal balance. It does not add $500 to the national debt.
How does the national debt grow?
When federal spending exceeds tax collections and other revenue, the government runs a budget deficit. Treasury sells securities to borrow money to cover the gap.
Consider a simplified, hypothetical example: the government collects $5 trillion and spends $6 trillion in one year. That leaves a $1 trillion deficit requiring financing.
A deficit measures a shortfall over a period, usually a year. Debt measures outstanding borrowing accumulated over time. Repeated deficits generally increase that debt. Interest on existing borrowing is also a federal expense.
Does paying off your credit card reduce the national debt?
Paying off a card reduces what you owe your lender. It does not directly repay Treasury borrowing. Household debt and government debt can influence the same economy, but they remain separate obligations.
When discussing debt, ask: Who borrowed the money? That one question helps distinguish a family’s finances from the federal budget.

October Meteor Showers Give Phoenix Skywatchers a Reason to Look Up
Phoenix skywatchers have several chances to catch October’s meteor showers. Here’s when to watch the Taurids and Orionids—and how moonlight affects the view.
Last Updated on October 10, 2026 by Daily News Staff
PHOENIX — October is bringing several opportunities to spot shooting stars over the Valley, with the Draconids reaching their October 8–9 peak and more meteor activity ahead.
The Draconids remain active through October 10, although viewers should expect a light display as the peak passes. Under favorable conditions, the shower typically produces only a handful of meteors per hour. timeanddate.com
Next, the Southern Taurids have an annual activity peak around October 14. Known for occasional bright fireballs, the shower continues into November. The stronger Orionids peak on the night of October 21 into the morning of October 22, typically producing 10–20 meteors per hour under dark skies. A bright Moon will interfere with this year’s display. American Meteor Society
The Orionids originate from debris left by Halley’s Comet. For Phoenix viewers, the best opportunity will be after moonset and before dawn, weather permitting. City lights will further reduce the number visible. amsmeteors.org
NASA recommends finding a viewing area away from streetlights, allowing about 30 minutes for eyes to adjust, and watching a broad stretch of sky. No telescope is needed—just a comfortable chair and patience. NASA Science
