WEST SEATTLE -- Every seven or eight minutes, a King County Metro bus rumbles down 26th Avenue Southwest.

With each passing bus -- hundreds of them each day -- Bob and Sue Lintott feel the shaking and rumbling.

"It's not peaceful and pleasant," said Sue, who worries the thumping is even affecting her pacemaker. "It makes me uneasy."

Down the block, Matt Kelleher also fees the rumble with each passing bus.

"It wreaks havoc on the street," said Kelleher. "All of our houses shake when a bus goes by."

Both Kelleher and Lintott point out new cracks in their ceilings and walls within the past several months.

They, along with more than a dozen other neighbors near Westwood Village, say the problems started when King County Metro expanded its Rapid Ride service from the new hub at Westwood Village a few years ago.

Chris Stripinis, who lives on Roxbury Street Southwest, was the first neighbor to take action.

He borrowed a seismometer to measure earthquake-level vibration on his living room floor as buses passed by.

"I'm glad the buses are here," said Stripinis. "But we can't have our homes crumbling and shaking because the buses drive by."

According to Seattle Department of Transportation spokesman Rick Sheridan, the city wants Puget Sound Energy to pay to replace roadway panels.

King County Metro started ordering drivers to slow down on 26th Avenue at the beginning of the year. Now they must drive 20  mph  -- 10 mph slower than the speed limit.

There are no plans for route adjustments, says a spokesman.

The city is also trying to make improvements to the road itself.
