HANSVILLE — One major public project in Hansville is wrapping up this month, just in time for another to begin.

Kitsap County Public works expects to fully open Hansville’s southern entrance this week as it completes reconstruction of Cliffside Road. Meanwhile, the state Department of Ecology is set to begin a toxins cleanup project in downtown, which will interrupt traffic on Twin Spits Road, the northern entrance to Hansville.

The county is completing the three-month, $917,000 Cliffside project several weeks ahead of schedule, said Kitsap County Public Works Construction Manager Jacques Dean. That means the county’s work will be done before Ecology begins the cleanup project, scheduled to start Sept. 20.

“We should be done and out of there by the time they begin,” Dean said.

Contractors widened and straightened Cliffside Road, between Hood Canal Drive and Little Boston Road. Cliffside is now a throughway, while a stop sign was installed on Little Boston Road. The county also improved stormwater catchments on the road.

Crews repaved Cliffside Road this week. Miscellaneous work will continue through September, including adding guard rails and new signs.

The county never fully closed Cliffside Road, but traffic was often alternated through the worksite and wait times of 20 minutes or more were common. Dean said his office received only a few complaints and all were traffic-related.

As the county wraps up work on Cliffside, the state Department of Ecology is finalizing a contract for the Hansville toxins cleanup project.

The roughly $1 million, federally-funded project will remove contaminated soil and groundwater from the area of the Hansville Grocery and Provision Company. The soil was contaminated by diesel and gasoline fuel that seeped out of buried tanks at a former service station on the site. The contractor will scoop out up to 2,100 cubic yards of soil from beneath and around the store, according to the action plan for the project.

Hansville Grocery will remain open during the work. Twin Spits road will be limited to one lane during parts of the project, which is expected to last several months.

Project Manager Mark Adams said Snohomished-based Wyser Construction was the low bidder for the work and Ecology is negotiating a contract with the company.

Adams said the drizzly weather was to be expected for a fall project. Ecology moved the start date of the project to September to accommodate the concerns of Hansville business owners.

“September can be a really good month or a little rainy,” Adams said. “This is Washington. Work goes on.”
