This article from the Sacramento Bee examining the continuing problem of speeding bicyclists on the multi-use trail through the Parkway, is a good presentation of the issue.
This is an issue we believe can best be addressed by separating the multi-uses so that each of the various Parkway users—runners/walkers, bicyclists, and equestrians, can more safely enjoy the beauty of meandering, or racing, along the river.
The best model we have seen is that developed by the Central Valley Rails to Trails Foundation who have designed a conceptual trail space approximately 40 feet wide, with 12 feet for bikes, 3 feet of plantings, 10 feet for walkers, 3 feet of plantings, and 12 feet for horses.
An excerpt from the Bee article.
“Cyclists who zip along the American River Parkway faster than the 15 mph speed limit may find their free-wheeling ways costing them $50.
“Starting as early as this weekend, Sacramento County rangers will be lying in wait – a LiDAR speed gun in one hand, a citation book in the other – to clock, warn and eventually cite cyclists who treat the crowded trail as a racetrack.
“If cyclists want to open it up, they really need to go out on the roadway,” County Regional Parks Chief Ranger Stan Lumsden said. “This is a multiuse trail with pedestrians, dogs, horses, strollers and joggers.”
“Cyclists have long been allowed to ride faster than the posted limit, often doing it safely. But as the parkway has gotten crowded, Lumsden said, rangers have noted more speed-related crashes, including some serious head-on collisions.
“Lumsden said parkway groups and users complain about unsafe riders, especially clusters of cyclists hitting speeds of 30 mph.
“People say it’s a long time coming,” Lumsden said. He acknowledged the effort will be controversial. “Yeah, but everything we do is.”
“The citations will be issued under the county park code. They will not be reported to the Department of Motor Vehicles, and will not affect a cyclist’s driver’s license standing or car insurance, Lumsden said.
“County officials said the fine will be $50 for a first violation, and $100 for a second violation of the same ordinance within one year.”
