At the lake where I ride, they were forced to drain one of the soggy wetland ends, pull out all kinds of plants, and put gravel down there because a doctor walking through the soggy trail threatened to sue the city and state if he ever tripped and injured himself because of the poor trail upkeep.

He didn't even actually get hurt, just threatened a lawsuit. I have to think if people in your park have actually been hurt - and it could just as easily have been the cyclist forced off the road and into a tree who broke a bone (I shared a story here a long time ago about a young friend of my daughter's who went over a 12-foot embankment because a clueless pedestrian didn't yield the lane) - that there are threats of legal action flying about. That's enough to make the higher-ups make all sorts of official restrictions, if only to cover their collective posteriors in case of lawsuits.

There's a posted 15mph speed limit at our lake, and there are huge signs posted at both entry points telling people to keep right. (Not that it works - that clueless pedestrian didn't pay attention.) It's a MUP, including cars and trucks heading down to the fishing holes. Maybe you could recommend something like that to your council people.
