Safety improvements planned along Trib 90

   WOODINVILLE--Few, if any, accidents have occurred there, but vehicles and pedestrians may soon be better protected from sliding off a roadway into a deep ditch near the Hollywood Hill Schoolhouse.
  
   This Monday, the Woodinville City Council will look at placing either guardrails or concrete barriers along 148th Ave. N.E. where it parallels the creek known as Trib 90.
  
   Safety has worried the council, city staff and King County since Trib 90's streambed was widened and deepened last summer.
  
   "We do need to take care of that," said Mayor Don Brocha. "It needs to be much safer."
  
   Right now, only plastic barricades and a thin strip of pavement separate cars and walkers from an up to six-foot drop into the creek bed inside the city limits.
  
   Deborah Knight, city public services assistant, says there are pluses and minuses to both types of barriers.
  
   Concrete would be cheaper as well as easier to install and remove, she said, while guardrails would require working with Puget Sound Energy because of a buried gas line.
  
   The posts and galvanized metal beam would look better, but construction would probably also impact traffic, she added.
  
   A barrier between traffic and the creek wasn't included in the original plans agreed to by Woodinville and King County when they teamed to work on the creek to prevent road damage from flooding. Only during excavation of the channel to 100-year flood standards did it became apparent that something had to be done.

   Afterwards, there were disagreements between the city and county on who was responsible for designing safety accommodations there.
  
   Now, the county is planning to guardrail 148th north of 147th Pl. N.E.

   The city is also proposing that a 230-foot path with a handrail be built in the city right-of-way just east of the creek to ensure pedestrian safety.
  
   The county will ask the city to sign an amended project agreement that would allow both parties to spend up to $200,000 more to finish work on Trib 90.
  
   Woodinville would be responsible for half with the other half split between the county's Road Services and Water and Land Resources divisions. Knight hopes to have something in place this fall.
  
   Despite the imposing plunge, police could only recall one accident where a car went into the ditch.
  
   Last January, a Nissan Sentra was struck and shoved into the creek bed by a Chevy Astro van.
  
   Nobody was injured.
