NASHUA — A large brick mill building on East Hollis Street could soon be transformed into 80 apartment units.

On Thursday, city planners will review a proposal to convert the former Henry Hanger Company of America factory building into an apartment complex developed by East Hollis Street Acquisitions, LLC.

According to Linda McGhee, deputy planning manager, the site at 110 East Hollis St. is being considered for 80 apartments — a mix of studio, one-bedroom and two-bedroom units.

“Renovation of this structure for housing will bring the building into code compliance, will enable accessible access to the building, will improve the building and provide a use that will enable the existing building to survive as an important piece of downtown infrastructure while simultaneously activating the streetscape with increased pedestrian activity,” Robert Harbeson of Market Square Architects states in the plans on file at Nashua City Hall.

He said the project, if approved, would enable the long-term sustainability of an important existing mill building for the neighborhood, and also provide a density of walkable pedestrian activity complete with a bus stop and within walking distance of a site previously eyed as a future train station.

“The development of 110 East Hollis St. has many benefits to the city of Nashua,” said Harbeson. “It will be a significant redevelopment of an existing building in the Transit Oriented Overlay District, and will act as a catalyst for future development.”

The site, which sits on a nearly one-acre parcel, includes the existing five-story, 90,000-square-feet mill building that was constructed in 1990 and previously occupied by the Henry Hanger Company of America.

“Access to the site will be provided by two existing driveways that intersect the north side of East Hollis Street. A portion of the building is to be razed and a part of the existing pavement will be removed to install landscaping,” McGhee said in a staff report to the planning board.

If approved, there will be about 68 parking spaces, with some of those located in a remote parking area that is to be constructed on the south side of Temple Street, according to McGhee.

Aside from the proposed apartments, a site plan suitability report states that the first floor of the building has the infrastructure to accept future first-floor commercial uses as more development occurs in the district.

“This project will breathe new life into a tired building, ensuring its long-term viability to survive as an anchor for the neighborhood and to work within this zoning toward its goals,” said Harbeson, adding the development will add market-rate housing to the downtown area, improve the connectivity of neighborhoods and add consumers for downtown businesses.

A traffic analysis has been conducted to determine how the proposed project would impact traffic flow. According to the analysis, the apartment complex would generate about 28 vehicle trips during weekday peak hours in the morning and about 36 vehicle trips during weekday peak hours in the afternoon.

Thursday’s planning board meeting begins at 7 p.m. at Nashua City Hall.
