Slowly, Downtown Los Angeles is becoming the place to be.

It is a place that has seen many a makeover in its time, slowly evolving from a work-centric hub, to an entertainment epicenter.

And in just 15 years, a whole lot more could be different, experts say.

The city is expected to see an unprecedented growth in its population — more than doubling over that period of time.

Transportation is the culprit. Finally, a reliable, easily accessible line of rails will carry passengers around the 15 different districts and neighborhoods.

Experts also contribute the change toward an evolving demographic group, which favors urban life and its wealth of activities to the suburbs and “backyard work.”

Of those 15 districts, the Historic Core — once lined with popular movie palaces — might see the most change. Remnants of those movie palaces still remain, but most no longer show films. A new streetcar and councilman Jose Huizar’s “Bringing Back Broadway” campaign could make it a more popular destination for Angelinos and tourists.

AECOM is also focusing much of its work on the Fashion District, hoping to make it a little more desirable to the entertainment crowd.

Much of that entertainment crowd has found delight in the fairly new LA Live center in downtown’s South Park district. AEG — which owns LA Live and the Staples Center — hopes to further transform South Park with its proposed Farmers Field football stadium.

The prospect of that stadium is already drawing much retail interest to South Park, which has not seen much of the growth experienced throughout downtown in the last decade.

More lofts, more entertainment, more of everything is on its way, experts say.
