Marco Gonzalez of the Coastal Environmental Rights Foundation said the cove is the wrong place for fireworks.

"The entire shoreline in La Jolla per the La Jolla community plan is a sensitive resource. It's highly protected," said Gonzalez.

For months, Gonzalez has been issuing warnings about the need for environmental studies and proper permits.

"Basically, they've dropped the ball on even trying to get the permits, which we believe cannot be issued even if they had applied for them on time," said Gonzalez.

With the legal battle heating up, the La Jolla Community Fireworks Foundation, who is organizing the show, declined 10News' interview requests. However, the nonprofit group's website told people to spread the word that the show is on. The group stated: "We have been assured by our legal advisors that there is a very small chance of any legal efforts canceling our beloved Fireworks … There is no definitive evidence suggesting Fireworks launched from our Cove pollute or pose any dangers ..."

"I'm very confident that they should stop it in San Diego County. You never know what the courts are going to do, but we will be filing a lawsuit this week," said Gonzalez.

Some local residents don't see what the big deal is.

"I don't really understand what their gripe is. One time a year, and it really causes that much damage," said La Jolla resident Anthony Paula.

San Diego City Councilwoman Sherri Lightner, who represents the La Jolla area, called the July 4 fireworks a signature event for the community.

"We made sure they got their permit from the city of San Diego and they had their vetting for the event, and we're trying to do their fundraising. At the present time they're still fundraising for the event," said Lightner.

As for the possibility the show could be canceled, Lightner said, "I sincerely hope not. I think all parties involved are well aware of the possibilities here."

Gonzalez said if there are fireworks at La Jolla Cove on July 4, he said he would be there with police and a restraining order.

Legal challenges against fireworks shows at the Del Mar Fairgrounds and the Port of San Diego are still being worked out, but those shows are no longer in jeopardy of being canceled this year.
