ROTTERDAM — Plans for a Walgreens at the former Capitol Plaza in Rotterdam are back on the table.

Less than three weeks after a spokeswoman disclosed that the Illinois-based pharmacy was no longer interested in a project to build a 14,700-square-foot store on the bustling corner of Altamont Avenue and Curry Road, a developer under contract with the company said plans are back on track. Bob Blank, a principal with HDB and a developer for the drugstore chain, said he is anticipating preliminary work on the building to begin sometime next month.

“I’m going to move forward,” he said during a phone interview Thursday. “We plan on proceeding with the plan as presented to the town.”

Town officials confirmed Blank’s intentions. Rotterdam Planning Commission Chairman Lawrence DiLallo said he met with Blank Thursday to discuss advancing the project in accordance with what the town approved in 2006.

“He’s telling us he’s confident in the next couple of weeks he’ll be able to resolve his contract issues with [Capitol Plaza owner] Jeff Musiker and go forward with the deal,” he said.

The Walgreens project is slated to be discussed by the commission during their first meeting in September. DiLallo said Blank must reapply for a special-use permit he had received to add a drive-through to the building, since it expired earlier this year.

Town Planner Peter Comenzo said Blank seemed earnest in his efforts to build the Walgreens and even presented final drawings to the town during their meeting.

Attempts to contact Walgreens were unsuccessful Thursday.

In 2005, developers proposed demolishing the 1950s-era shopping plaza to make way for the chain pharmacy and a 65-space parking lot. The project faced numerous setbacks, including a lengthy relocation of the plaza’s 14 business tenants and the acquisition of a sliver of state Department of Transportation-owned land adjacent to the plaza.

The last business left the plaza in February, and Blank had initially discussed demolishing the structure in March. Then nearly five months later, a Walgreens spokeswoman disclosed that the company was no longer interested in locating a store in Rotterdam.

Initial reports of the deal’s apparent failure perplexed Blank, Musiker and town officials. At the time, Blank insisted that he would pursue the project, but not without Walgreens on board.

Blank said the apparent problems with the deal arose when Walgreens removed the project from their active project list. He said the company routinely opens about 400 stores per year, so it’s not difficult for some of the longer-term projects to fall out of their purview.

“The [Rotterdam] store had been removed from the list because it was put on hold,” he explained.

Blank said his discussions with Musiker have been in an attempt to make the project economically feasible. And while the deal hasn’t closed, he’s confident that the project will advance to the demolition phase sometime this fall.

“It’s been a bit of a dance,” he said of the ongoing project.
