North Plaza Friction Slab Traffic Safety

At our Seattle Program Center, large courses using the friction slab often spill out into the nearby busy streets. Climb leaders are strongly encouraged to place cones during use of the friction slabs or when participants are crossing the street.

The North Plaza friction slabs at our Seattle Program Center have become a popular resource, and it's important we keep safety in mind during course instruction. We ask you, as leaders and participants, to be aware of large groups spilling out into nearby streets or frequently crossing the eastern roadway, as this creates the potential for a traffic accident. 

In the interest of safety for both slab users and drivers, climb leaders are strongly encouraged to place cones during use of the friction slab, or when participants are crossing the eastern roadway to practice glacier and climbing techniques on the grassy knoll across the street. 

Traffic cones are provided. These are located at: 

  • The friction slab gravel area 
  • The north storage area 
  • The Mountaineers basement

The following images are recommended examples of how to place traffic cones along the western and eastern roadways.

Western road facing north. Traffic cones divert traffic away from the area and warn drivers of the nearby activity.

 

Western road facing south. Traffic cones divert traffic away from the area and warn drivers of the nearby activity.

 

Eastern road facing south. Traffic cones divide traffic to slow speeds and warn drivers. 

 

Eastern road facing north. Traffic cones divide traffic to slow speeds and warn drivers.

While friction slab activities are the focus, those activities which circumnavigate the building also need advanced vigilance and protection.

Further suggest:
>>all twilight and later participants wear headlamp0s
>>paint a fog line and ask for forgiveness later
>>set up flag depots for crossing at several points
>>set up horses and caution tape between them to harness errant students and instructors
>>recruit Cascade Bicycle colleagues to do a ride in to slow traffic -- call the press first
>>Set up reader board (like US2) that displays number of days since last Close Call
>>Invite soon to be elected new Seattle City Council rep for our district to join the club
>>Reserve six to eight parking spots on W side of byway for Mountaineers cars that will sport rooftop, red flashing lights oriented to oncoming traffic
>>Park decommissioned police car on W side with obvious radar device
>>Erect sign with rotating messages: Beware Microspikes...Speeders Will Be Alpine Scrambled...Ball Nutz in Roadway...Alien Cams Reported
