City of Issaquah officials are presently in negotiations with three north Issaquah property owners to acquire parcels vital to a planned road extension.

City Public Works engineering staff have planned to acquire properties from Bass and Bass Partnership, Reid Family Investments LLC and Puget Sound Energy to widen Southeast 62nd Street and install a roundabout at the intersection of 62nd, 221st Place Southeast and Fourth Avenue Northwest.

But with project design and permitting set to move forward in 2016 — and $6 million tied up in 2016’s share of project work, including property acquisitions — city staff are lining up their ducks to ensure the acquisitions happen no matter what.

On Monday, the Issaquah City Council will vote on whether to authorize the use of eminent domain if negotiations fail.

“All affected property owners have been notified of the project, the city’s right-of-way needs and of the agenda bill with the upcoming action at Monday’s council meeting,” senior engineer Brianne Ross said.

Public Works Engineering Director Sheldon Lynne told members of the City Council at a March 9 Infrastructure Committee meeting that eminent domain was standard “due diligence to protect the project and the schedule for whatever reason.”

The text of the agenda bill authorizing eminent domain noted that the city has already had “positive and collaborative” initial conversations with Puget Sound Energy and the Bass and Bass Partnership over property acquisitions.

The city has also established contact with an attorney for Reid Family Investments, city Public Works officials confirmed Monday.

The road widening is part of a planned extension of Southeast 62nd Street from East Lake Sammamish Parkway Southeast to Lake Drive in Pickering Place. The extension has been planned for more than two years and, in Oct. 2014, Costco Wholesale officials agreed to foot part of the bill on that and other north Issaquah transportation projects as part of a deal to expand its headquarters in Pickering Place.

Randy Bass of Bass and Bass Partnership was initially opposed to the taking of land from his truck rental and storage business on Southeast 62nd Street to accommodate the planned roundabout.

Bass spoke out repeatedly at City Council meetings in 2014 and his partnership filed a civil lawsuit against the city that same year.

Contracted appraisers are currently determining the value of the parcels under negotiation. They are expected to have their appraisals in May, Ross said.

On Monday, the City Council will also vote on whether to exempt the city from paying relocation assistance to property owners and tenants in addition to compensation for the parcels. The city can exempt itself from paying for relocation because the project is not federally funded, Lynne said.
