The Islip Town Board will vote Tuesday on a proposal that would keep alive a bid to develop a former landfill in Bay Shore into a Costco store.

The resolution would authorize the town to enter into a contract to sell the 22-acre contaminated parcel at Sunrise Highway and Denver Avenue for $25,000 to North Babylon-based P&M Builders.

As part of the proposed deal, P&M would be required to remediate the site adjacent to the town's animal shelter.

P&M would construct the 140,000-square-foot Costco and build a new animal shelter nearby.

The passage of the resolution is critical to the future of the project, which has been in the pipeline since 2009, town officials said.

Councilwoman Trish Bergin Weichbrodt said the resolution is "an effort to help Costco and P&M facilitate their investors' concerns regarding their ability for this project to go forward and to get financing."

Bergin Weichbrodt, the deputy supervisor, said the low $25,000 proposed selling price is an acknowledgment of the estimated $25 million cost to remediate the site, which closed in 1982 after serving as an incinerator, a waste treatment facility and a construction landfill.

"This is a brownfield -- it's a contaminated site that we would like to see cleaned up and unfortunately municipalities don't have the money," Bergin Weichbrodt said. "And when you have a private company that would create jobs and a tax base, we get excited about that."

A representative from the Washington state-based mega-wholesaler Costco said the company does not comment on stores that are not under construction.

Officials from P&M Builders did not return a message seeking comment.

Islip Town officials have estimated that the store would create hundreds of jobs.

The project still needs zoning approval.

The Islip Town Planning Board held a public hearing on the requested rezoning from industrial to business in November.

No one from the public raised concerns.

The application is still pending.

The town board, which voted in June to enter into exclusive negotiations with P&M, gives final approval to all zoning applications.
