It depends on what kind of civil engineer you want to be.
If you know you want to work with structures, like buildings and bridges, then UCSD could be a great choice. That’s their specialty.
If you know you want to work with other aspects of infrastructure, like roads, tunnels, drainage, water supply, pipelines, or environmental issues, then UCSD is probably not be a good choice. They specialize in structures, not these other things.
If you don’t yet know what kind of civil engineer you want to be, then UCSD may not be a good choice, because they don’t offer the full spectrum of options. Again, they specialize in structures.
