The County Board of Supervisors Tuesday voted to move ahead with the idea. It means people who live closest to the river would pay up to $30 a year towards clean-up efforts.
But Supervisor Roger Dickinson says he thinks the county should adopt an assessment that would benefit all parks.
"We have a lot of other assets which frankly are just as badly under funded than the parkway and so the real question ultimately comes down to is: ‘is there any reasonable prospect that this can be expanded into something more in the future?’"
Supervisors directed staff to keep working on the plan.
The 23-mile parkway stretches through Sacramento, Rancho Cordova and Folsom.
