Got the big basshorns going, do you?
Honestly, you have a tough problem to solve. Generally, you can either absorb the sound or contain it, but both are pretty hard to do at bass frequencies. Best if you can go with a solution that covers both bases, a large concrete wall for isolation, and a lossy membrane between you and that wall for absorption. It's going to be expensive.
