Expansion plans for the Cabrillo Marine Aquarium will be discussed at a community meeting today.
Proposals include a 1-million-gallon swimming tank where ocean life from around Santa Catalina Island and the shores of Los Angeles can be viewed up close.
But first improvements would be made to Cabrillo Beach, with a plan to turn it into an educational and recreational park.
The expansion is expected to occur in phases over the next 10 years and to cost about $45 million in private and public funds, said aquarium spokeswoman Susanne Lawrenz-Miller.
Other likely additions include new marine education laboratories and classrooms, a restaurant, a home for rescued sea otters and more touch tanks.
The facility belongs to the Los Angeles Department of Recreation and Parks.
The 7 p.m. meeting will be in the John M. Olguin Auditorium of the aquarium at 3720 Stephen White Drive.
