I have attached the plan that contains the boat launch and access road and an aerial photo. , Hopefully you can open it. planno0914922.pdf
The boat launch and the access road are owned by the city. The property line on the southern boundary of the condo complex appears to be on the existing fence.
Anyway, what we don't know with certainty is who is putting up the chain. If it is the condo people or their security firm who is doing it then it is likely unlawful unless they have an agreement with the city. I am looking into that. Regards
