Any parks in Bellingham where people are generally respectful of on-leash requirements?

I wanted to take my dog out today to Marine park for a bit, and there's a guy playing with his dog off-leash for what seems like 394934843834983984 hours straight.

Correct me if I'm wrong, but this is a on-leash area, correct? I know I can't (however reasonable) expect people to be following on-leash requirements, so next question, is there a place where I can go where people are generally respectful of leash laws?

Just want to take my dog out for a bit without any unnecessary confrontation/dangers. Any advice appreciated! And any clarification on leash regulations that I might not be understanding correctly.
