Amazon.com's ( (AMZN) - Get Report  new Texas fulfillment center in San Marcos isn't open yet, but the company is already advertising for open positions.

Eventually more than 1,000 workers will be employed at the 855,000-square-foot facility, which San Marcos helped secure through business incentives. It's all part of a push to help expand business opportunities in the greater San Marcos region, one of the fastest growing areas of the U.S.

San Marcos is located along the busy I-35 corridor between San Antonio and Austin, which are both rapidly growing metropolitan areas.

San Marcos Mayor Daniel Guerrero said that a new company opening its doors in his city a few years go might have employed less than 100 workers. But that's changed now with bigger companies like Amazon setting up shop.

"Those are trends we're seeing more and more of -- greater investments and greater job counts," said Guerrero.

The city has worked with area universities and colleges to make sure employers can find skilled workers, and has also worked to keep taxes low. In addition, Texas does not have a state income tax.

San Marcos had to make infrastructure investments as a way to attract new industry. Guerrero said the city is exploring a possible new bond offering to finance additional expenses.

"We are looking at that. It's been a good while since we've gone out for a bond as a municipality. I believe it's been about five or six years. We actually have not raised taxes in almost eight years," said Guerrero.

The mayor added that he'd like to see state and federal funding of infrastructure projects that would benefit the San Marcos area.

"The pace of growth we've seen has been tremendous," said Guerrero. "So receiving that help from both the state and federal government is of significant urgency for us."
