Human Impacts at Brackett's Landing

I visited Brackett's Landing in Edmonds. It is the beach right next to the Edmonds-Kingston Ferry. The tide was very high, there is a rocky area that jets out into the water. There is a large bathroom and changing room shelter and a big spigot/ outdoor shower. There is an underwater dive park here as well. One of the major impacts you first notice is the ferry and other boats. Boats have the potential of leaking oil into the water, running over animals, and some people are not responsible and can end up having litter fly out of their boats and into the water. Another impact that I think is worth mentioning is the human scuba divers. Although I'm sure most divers are trained and knowledgable about not disturbing wildlife in the underwater dive park, I'm sure there are some that are not. I was surprised to not see any litter. There are many garbage cans so that might be why. I did found a tarp-like thing sticking out of the sand, but I think that was put there when the beach was built, because I am 90% sure most of the sand at Brackett's Landing was brought in from elsewhere. I could see seagulls trying to peck at this tarp which could end up injuring them or end up with them swallowing pieces of tarp leading to intestinal problems. Something I think that could be done about the ferry boat is to have less trips back and forth across the water. I'm not sure what could be done about the private boats people own, maybe only have certain times that the boats can go out to reduce boat activity in the area. I hypothesize that if boating activity was decreased, the disturbance of the ecosystem in the area would decrease.
