The registry starts the screening process for local businesses that want to help build the ExxonMobil and SABIC plant.
Johnson and his colleague Tracy Ross hope it will bring years of work.
"It's a huge investment, we just want to be part of it," said Ross, Area Sales Director. "We'll move more product, hire more people. We're going to expand."
They say local vendors are often left out of big projects, but they think that will change with the Exxon plant.
"They seem like they want to be a good neighbor, take care of the local people. Which sometimes we don't get to participate in all of that, but it looks like they're going to try and do something about that," Ross said.
At Gulf Coast Growth Ventures, they say that is exactly the idea.
"It does ensure local businesses will get consideration for the competitive bidding that's going to take place over the next year," said John Mabry, Operations Manager. "It's good for us too, because local businesses have infrastructure here."
Mabry says they hope several thousand local businesses will join the project.
"Wide range of businesses. So anything from on-site services, which would be construction crafts, industrial cleaning, that sort of thing. To off-site services as well, which could be caterers, hotels, office supplies. So really, anyone can apply," he said.
If those businesses need help getting qualified, Del Mar College's Small Business Development Center has partnered with the project.
"Any stumbling blocks along the way a business might run into, we're here as a resource to help them work through those," said Director Ann Fierova. "We want to see as many small businesses get involved and see returns on these opportunities."
The project is expected to generate billions of dollars in business activity.
"They'll be here 60 years, and we'll be here 60 years," Johnson said. "We think there's going to be a lot of growth in this area going forward."
The first phase of registration will last through June 30th, then that list of pre-screened companies will be sent over to contractors for consideration. Vendors can still register on the online portal after the June deadline.
