Fifty-two trees to be moved for Expo Line in Santa Monica (Santa Monica Mirror)

Before Expo Phase 2 construction begins along the right-of-way, the city of Santa Monica will remove 52 trees from the southern edge of Olympic Boulevard between Stewart Street and Cloverfield Boulevard. Fear not, 38 of them — palms, ficuses and others — will be finding a new home nearby. The Mirror cites a Santa Monica staff report stating that the city may use some of the trees to create a “buffer” between the new Expo maintenance facility and surrounding homes. Note: The coral trees in the center median of Olympic are not the trees being moved.

U.S. Conference of Mayors report: nation’s transportation infrastructure needs to keep pace with growing exports (Progressive Railroading)

U.S. exports are on the rise and that’s good news for the local economy. After all, the Ports of L.A. and Long Beach combined handle more cargo than any other port in the country. But that also means more freight moving on our local rails and roads, and more congestion as a result. That has Antonio Villaraigosa — in his capacity as L.A Mayor, Metro Board Chair and U.S. Conference of Mayors head — championing more federal investment in the infrastructure that helps move freight from ports to local warehouses and those throughout the country.

Report from last week’s DTLA bike sting (L.A. Streetsblog)

How effective has the new bright green Spring Street bike lane been at keeping bikes and cars at a safe distance? The LAPD sought to determine that last week through an enforcement operation against rule breakers. Streetsblog writer Carlos Morales checked in on the “sting” and found some clueless drivers, obstructing film crews and the occasional confused cyclists — on top of everyone else who was getting along well enough. My thought: If the bike lanes were physically separated from traffic — a la those in Long Beach, Montreal, New York — a lot of these problems would be engineered away.
