The Cajun Navy is sailing from a command post in Oakland this summer, bringing relief to Louisiana victims of August’s flooding that destroyed tens of thousands of homes and interrupted the new school year.

Beau Bergeron, 31, a native of Baton Rouge living in West Oakland, is dispatching $50,000 of cash aid to seven nonprofits that are helping out.

“I’m loyal to the Bay Area; this is where I want to be for a long time,” the graphic designer said by phone.

“But I’ll always be from Baton Rouge. My family is there still,” he said.

The money comes from sales of Bergeron’s T-shirts that honor boat-owning volunteers who rescued some of the 30,000 people who needed evacuation when tropical storm rains began falling Aug. 12 and did not stop until 7.1 trillion gallons of water had inundated the state in the nation’s worst natural disaster since 2012’s Hurricane Sandy tore up the East Coast.

Along with his work doing Web design and branding, Bergeron came up with 30 T-shirt designs.

The designs include a series that resemble Andy Warhol’s iconic Campbell’s soup cans, except the brand is Louisiana and the images include red beans and rice, collard greens, crawfish etouffe, chicken jambalaya, seafood gumbo and alligator stew.

Others show maps of Louisiana, some with images of Cajun Navy volunteers plying the waters.

Bergeron got the effort started with a simple post on Facebook to his 1,000 followers. “It went very viral,” he said, and was soon shared 5,000 times.

In Baton Rouge, kids are just getting back to classes. Schools have had to merge and stagger their hours to accommodate children and teachers who no longer have a building to attend. Students, faculty and staff have all had to cope with the disruption.

“The governor’s office estimates that 10,000 seniors have been displaced,” the East Baton Rouge Council on Aging wrote in thanking Bergeron for his contribution.

“Many more will need assistance from our agency,” it said.

Bergeron and his partner in the project, custom T-shirt distributor Teespring, have sent the nonprofit almost $10,000.

Other aid recipients are the Companion Animal Rescue of Ascension, which looks out for lost animals; Together Baton Rouge; St. Vincent De Paul; the Junior League of Louisiana, which has focused on infants; the Baton Rouge Food Bank; and Habitat for Humanity.

It is a drop in the bucket in terms of what is needed to restore the region, but an impressive effort nonetheless.

Others have come forward with aid. AT&T provided $100,000 to two organizations, while singer Taylor Swift has offered $1 million, and other performers, such as Harry Connick Jr. and Randy Jackson, organized a Labor Day concert to benefit the Red Cross Louisiana Flood Relief fund.

Teespring is selling Bergeron’s tees, sweatshirts, tote bags and tanktops for $21.99 to $26.99. They are available at https://teespring.com/stores/cajun-cool.

All proceeds are headed south.
