Buying property and building a new public safety building for the city of Bainbridge Island will cost between $13.8 million and $14.6 million, according to city officials.

The city is currently contemplating selling a number of city-owned properties — including the land known as the Suzuki property, the existing police station site near the ferry terminal, and surplus parcels at Head-of-the-Bay — to help pay for the project.

The Bainbridge city council has met multiple times in recent months behind closed doors in executive session to talk about land acquisition and other issues involved in the project. The council is expected to choose a location for the new combined police station/municipal court facility at its meeting Tuesday.

A timeline prepared for the council shows the city pursing a November election to pay for the project. City officials are considering a 20-year-bond measure that would raise property taxes to cover the costs of the project.

Two sites are under consideration, both located on Madison Avenue.

Costs for putting a new public safety on the site closest to downtown Winslow, on land just north of city hall, could cost between $13.8 million to $14.6 million, according to preliminary figures compiled by the city.

The costs of developing the other site, land owned by the Sakai family just north of the acreage on Madison Avenue recently sold to the Bainbridge parks system for the development of a central island park, would cost between $13.6 million to $14.2 million, according to the city.

The sale of city properties, including the Suzuki property, the current location of the police station on Winslow Way and the surplus lands at Head-of-the-Bay, will net approximately $4.5 million, according to a June 4 memo from Deputy Manager Morgan Smith to the council.

The city has had the surplus properties appraised, according to the memo, as well as most of the parcels that make up the two sites under consideration for the new facility.

The Sakai property, which spans 8.98 acres, has been appraised and the purchase price is expected to fall between $3 million to $3.5 million in preliminary estimates.

Land just north of city hall, which includes three parcels that total .75 acres, has an expected purchase price of $2 million to $2.5 million. Just one of the three parcels has already been appraised.

Beyond choosing a site for the new facility, the council will also be updated on the prospects for a November ballot measure to gain public approval of the project.

At the council’s meeting next week, council members will review funding options and make a decision on selling city land.

A ballot proposition calling for the election is expected to come before the council July 7.

If approved by voters, construction would begin of the new public safety facility by late 2016 or early 2017.
