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

Less than three weeks after a spokeswoman disclosed the Illinois-based pharmacy was no longer interested in building 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 chain drug store, said he is anticipating preliminary work on the building to begin sometime next month.

“I’m going to move forward,” he said today. “We plan on proceeding with the plan as presented to the town.”

Town officials confirmed Blank’s intentions. Town Planning Commission Chairman Lawrence DiLallo said he met with Blank today 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.

In 2005, developers proposed demolishing the kitschy 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.
