Austin's light rail project cleared a key federal review in January, marking a "major milestone" in the multibillion-dollar transit system's ongoing development.

The details: Roughly half of the light rail's $7.1 billion price tag will be covered through federal grants that require an extensive Federal Transit Administration review and approval. As one step in that funding process, Austin Light Rail entered the FTA's National Environmental Policy Act, or NEPA, review about two years ago. The federal agency has now issued its record of decision for the transit system's Final Environmental Impact Statement, or FEIS, advancing the light rail program's planning and moving it closer to securing needed federal grants.

Quote of note: "Completing the Final Environmental Impact Statement and earning the FTA’s Record of Decision in under two years is a major achievement for Austin Transit Partnership and the community we serve,” ATP CEO Greg Canally said in a statement.

Austin's rail became the first major transit initiative to finish its FEIS within a federal guideline of two years, according to the ATP.

Austin ISD has again asked self-driving car company Waymo to cease its operations during morning and afternoon school bus hours.

The big picture: The district has reported 24 school bus traffic violations by Waymo vehicles this school year. Four of these incidents occurred after Waymo issued a voluntary software recall in early December amid a federal investigation into the company by the National Highway Traffic Safety Administration.

What happened: During the week of Dec. 8, Waymo issued a voluntary software recall for its autonomous vehicles after AISD recorded 20 incidents of Waymo cars illegally passing district buses, averaging 1.5 violations a week, according to a letter from AISD to Waymo.

The update: As of Jan. 14, the district had recorded 24 school bus traffic violations by Waymo vehicles this school year, an AISD spokesperson said. Since Waymo announced its December software recall, the district recorded violations from Waymo vehicles Dec. 11, 12 and 19 as well as Jan. 12, according to AISD information.
