New figures from King County show traffic volumes during the Brightwater wastewater treatment facilities will be greater than first anticipated.
County officials are also looking at the possibility of barging pipeline construction materials to an existing dock at Chevron’s Point Wells facility.
Shoreline officials support the potential barging in of pipeline construction materials to a dock at Chevron’s Point Wells facility. This is preferable to having materials arrive from the roadway, according to Shoreline director of planning, Tim Stewart.
“That would be the ideal situation, to avoid the use of Richmond Beach Road as much as possible,” Stewart said.
The big issue, Stewart said, is determining how dirt will be transported away from Point Wells once it has accumulated from the digging of the tunnels. He said the city would be very supportive of removing materials, such as the dirt from the tunnels, by barge as well. The portal site is located near the dock.
The new figures are in an addendum to the final environmental impact statement King County issued for the Brightwater project. The addendum includes some new information about both construction traffic and temporary barge docking at the Point Wells pipeline portal on Puget Sound.
The information does not substantially change the analysis of significant impacts and alternatives in the final EIS, said Christie True, capital improvement projects manager for the county’s Wastewater Treatment Division.
“This is not unusual for a project of this size at this stage of the project,” True said. The new information includes a higher background traffic growth rate to analyze proposed volumes and possible construction-related traffic impacts for the Brightwater system.
