Flooding struck the area bordering lower Tributary 90 last Wednesday following the eight inches of rain that has fallen in this area during the month of March. A nursery was flooded, and the ball fields near the slough were inundated, as well. Tributary 90 comes down NE 146th Place and has jumped its bank near the Hollywood Schoolhouse several times in the past few years.
Mike and Christine Carlson, who own the nursery off of 148th Avenue NE, worked to contain the water and tried to direct it into a ditch bordering the Tolt Pipeline. But, before it was finally contained, the creek left another load of rock and silt on their land, which, before last January's floods, had been covered with reeds and grass. Now the field is covered with sediment.
The Carlsons said that the property had been used as a silt trap, and that the land should have been condemned. The couple explained that the land used to be a bulb farm, but the flooding which has struck the area in the last few years has left the land so wet that bulbs haven't been able to be planted there anymore. Their driveway has also flooded twice in one year.
Mike expressed frustration with the creek's path, saying there were too many 90-degree curves where the creek came up to 148th Avenue NE and then crossed under it again near the Tolt Pipeline. He proposed routing the creek down NE 145th Street.
Regulations regarding work on streams containing fish angered him, as well. He said Trib 90 was not a natural habitat for fish. "Somebody put the fish [there] in modern history," Mike said. "We have to figure out another way for the water to go."
The City of Woodinville recently signed an interlocal agreement with King County to work on lower sections of Trib 90. Plans include smoothing several 90-degree bends in the creek, enlarging culverts and the channel, and mitigating the project's impact on the fish habitat.
At the same time the Carlsons were working to prevent flooding, water poured into a ditch bordering several ball fields at the Sammamish River Regional Park. Everett Vonorden, field manager, noted that one of the fields had been recently re-sodded and games were scheduled to begin there Mar. 29. Of the water, Vonorden said, "We're going to leave it there and pray."
Near the Woodinville McDonald's, pipes taking water under 140th Avenue NE became jammed with rocks and sediment, which forced water out of a manhole, creating a large pool on the road. A description of the pipe obstruction was offered by a King County Public Works worker. "You've heard the saying 'solid as a rock?' Well, this is as solid as a ton of rocks," she said.
A high-pressure hose was brought in to free the blockage and after several minutess, water drained through the pipes again.
