Eastern Bank has provided a $28.37 million financing package and MassDevelopment has provided a $6.5 million New Markets Tax Credit financing and $3 million leveraged loan for Riverwalk Partners LLC, which is redeveloping the Riverwalk Mill complex in Lawrence.

The funds will help Sal Lupoli construct 210,000 square feet of new and redeveloped commercial space in two office buildings, including renovating 350 Merrimack St. and constructing a new building at 290 Merrimack St., as part of the second phase of this project.

"Eastern Bank is excited to be taking part in Lawrence’s revitalization, both through our financial commitment to the Riverwalk project and through the recent opening of our 96th branch location on Essex Street in Downtown Lawrence," said Jan Miller, executive vice president of commercial lending for Eastern Bank. "We are particularly pleased to be partnering with Sal Lupoli, a man with unparalleled commitment to improving our communities through job creation and responsible growth."

NxStage Medical, which had planned to leave Massachusetts, will instead move to 350 Merrimack St. and bring 400 jobs to the site. The company plans to add another 400 jobs over the next several years. Tenants at the new building at 290 Merrimack St. expect to add another 100 jobs. Officials estimate the project will create 166 construction jobs, according to a statement.

"This project marks another major milestone in the transformation of Lawrence’s historic mill buildings undertaken by Sal Lupoli," said MassDevelopment President and CEO Marty Jones. "MassDevelopment is pleased to help this visionary developer create and keep jobs in this key Gateway City."
