DEVENS -- MassDevelopment is expected to hire a developer in a few months to construct 120 new housing units in the Grant Road neighborhood after six companies have expressed their interest in taking on the project.

The quasi-public economic-development agency said Monday it has received responses to its request for qualification for the project by the May 24 deadline. The project encompasses 70 acres in the northwest section of Devens, which is the last piece of residentially zoned land in the former Army-fort community. The project calls for 20 percent to 25 percent of the proposed units to be "affordable."

MassDevelopment declined to release the names of the applicants while continuing to review the submissions. The agency said, however, the responses came from "experienced regional and national developers."

The MassDevelopment Board of Directors is expected to vote for one or more developers to work on the project at their Aug. 7 meeting.

The project comes more than a year after the agency's attempt to contract with Trinity Financial of Boston to redevelop the historic but abandoned Army barracks at Vicksburg Square into 246 apartment units. The proposal to rezone Vicksburg Square for the housing project failed at the tri-town Town Meeting on March 28 last year. The Grant Road neighborhood, on the other hand, is already zoned residential.

With 3,200 workers employed at companies in Devens, MassDevelopment has said the 4,400-acre former Army-post community, now know for its industrial park, could use more housing.

"We're thrilled with the response we've received from developers interested in the latest Devens neighborhood, and we look forward to diving into these proposals and finding the best fit for the community," MassDevelopment Executive Vice President of Real Estate Richard Henderson said in a press release.
