County Roads Division builds 'salmon expressway' on Rock Creek
King County Road Services Division staff look on as a
school of salmon (insert) makes its way up Rock Creek.The projects completed by the
King County Road Services Division in unincorporated areas not only benefit
motorists and pedestrians, but often they also enhance the natural environment
for fish.
That was the case on a
recent project
near Maple Valley that brought together improvements for Southeast 248th
Street, the Cedar River Trail, and a section of Rock Creek.
When the roadway on Southeast 248th Street began cracking and
sinking, road crews discovered that the 100-year-old wooden culvert that carries
water from Rock Creek under the road had crumbled and collapsed. And, the wooden
trestle – also a century old – that provides trail access over the road needed
to be replaced, as well..
In order to repair the road and replace the culvert and trestle, the county
had to navigate through a lengthy permit approval process that included federal,
state and local agencies due to the project’s proximity to a salmon-bearing
stream.
The old culvert, which was originally a timber flume, was narrow and cramped.
Few salmon were ever able to make it through the culvert to spawn upstream. So,
the county used the opportunity to create a much better fish passage.
"The new concrete culvert has now been installed and is as wide as two lanes
of freeway," said Project Manager Kok-Wah Tung, an engineer in the Road Services
Division. "We went from a five-foot wide culvert to one that is 26 feet wide –
more like a salmon expressway."
It’s obvious that the salmon are enjoying the new culvert and rebuilt stream
banks that are now more fish friendly and less prone to erosion. On a recent
rainy Monday, there were Coho and Chinook in the stream on both sides of the
roadway. Gravel for spawning has been placed throughout the streambed to further
improve habitat.
It is not always an easy task to design road improvements that also improve
fish habitat, but the Road Services Division has been tackling increasingly
challenging projects and is earning a reputation for this type of quality
environmental work.

Airport drill tests readiness at KCIA
King County
International Airport/Boeing Field held a mock disaster drill last Saturday
complete with a fake airplane crash and volunteer victims.The federally
mandated drill was designed to test the response of Airport Rescue Firefighters
and mutual responders in the event of an aircraft emergency involving serious
injury to the airplane and passengers.
The drill is conducted every three years and known as a Triennial Exercise.
It is required by the Federal Aviation Administration to enable the Airport to
maintain its operating certificate. All airports operating under regulations
known as FAR-139 certification are required to develop an emergency plan and
conduct such drills.
"This exercise was conducted to enhance the airport's training for response in
the event of an aircraft emergency, as well as providing an opportunity to
ensure the coordination between mutual aid departments and surrounding
hospitals," said Mike Colmant, KCIA Assistant Airport Director.
Other agencies participating in the mock exercise included the Seattle,
Tukwila, and Boeing Company fire departments, the King County Sheriff’s Office
and local police departments, the FAA, and the King County Office of Emergency
Management.

Hyde Shuttle now ready to serve seniors
Two new innovative and free transportation services are now
available to senior citizens and to people registered with
King County
Metro’s ACCESS transportation program in Southeast Seattle.
The
Hyde
Shuttle, named in honor of longtime Beacon Hill resident Lillian Hyde, went
into operation on Oct. 1. In her will, Hyde bequeathed $403,839 to King County
Metro’s ACCESS program to establish a shuttle service for seniors and people
with disabilities who reside in Beacon Hill and Southeast Seattle.
The shuttle van is lift-equipped and available on weekdays on a first-come,
first-served basis by calling (206) 727-6262, or TTY (206) 296-3701. It is being
operated by Senior Services, a non-profit organization serving seniors
throughout King County.
Hyde’s donation is also responsible for the creation of the new
Ride Options Hotline, a free telephone service for seniors and ACCESS riders
living in the area. The Ride Options Hotline connects callers with travel
advocates from Senior Services. The Ride Options Hotline is available weekdays
from 9 a.m. to 5 p.m. by calling (206) 296-3700, or TTY (206) 296-3701.

100 bridge inspections in a single day
In the wake of last week’s flooding, two engineering teams
and several bridge maintenance crew teams from the
King County Road Services
Division raced around the county on Oct. 21, inspecting more than 100 bridges
and looking for damage or flood debris hung up on bridge piers.Inspections
were concentrated in the north half of the county where rainfall was heaviest.
The bridges fared well, thanks in part to the level of the Snoqualmie River,
which held off from spilling across the entire width of the valley. Bridges in
the Skykomish River area also withstood the conditions, despite the highest
flows in that river since 1990. About a dozen bridges that were submerged,
inaccessible due to closed roads, or suspected to have scour-related problems
were slated for follow-up inspections as the water receded.
Floods actually provide a good education for bridge engineers. After each
high water event, engineers measure water heights and learn more about how the
bridges perform in high water, allowing them to prioritize future flood
inspections and repairs
And,
remember that 17-foot diameter pipe recently installed at Judd Creek on Vashon
Island? Here is a photo of the water flowing through the pipe early morning of
Oct. 21. According to Roads staff, if the new pipe had not been in place, it is
very likely the road would have been completely lost.
