HUDSON — The Hudson planning board reviewed a new self-storage project on Roosevelt Avenue Wednesday night. Meanwhile, work is beginning on an additional self-storage building in Derry that was approved in June.

On Wednesday, developer Jim Allard presented his plans to the Hudson planning board to build a 90,900-square-foot, three-story self-storage facility at 23 Roosevelt Ave. The plan is to combine the lots at 23 and 27 Roosevelt Ave. and demolish an existing 4,990-square-foot concrete building and parking lot before erecting the new building.

The new facility will also have a new parking lot with 19 spaces, and three detention ponds on the property.

“I’d like to be putting foundations in by late fall and erecting over the winter,” Allard said.

He said the existing building formerly housed a light manufacturing facility.

Allard, who is a contractor with experience renovating industrial and medical facilities, estimated the construction will cost about $3.5 million.

“This is my first self-storage,” Allard said.

He said the facility will feature climate-controlled units, two elevators, security cameras and high-tech access options.

Town Planner Brian Groth said only two neighbors spoke during the public input session, both in favor of the project.

Groth said the board recommended a few minor changes to the plans, including lowering the light fixtures and outlining the signage details. He also suggested developers draft a cross-section of the property to showcase the significant grade change between the property and nearby residential properties.

The fact that the self-storage property is much lower in height and surrounded by tall pine trees in the back will help reduce visibility, he said.

The board voted to continue the project to a public hearing on Aug. 14.

Meanwhile, developers for Derry Self Storage on Ashleigh Drive are building a third and final facility, which was approved by the planning board on June 5.

The developer for the project is Yvon Cormier Construction Corp., based in Andover, Mass.

Derry Town Planner George Sioras said developers are holding pre-construction meetings with the building department and the public works department. The building will replace an existing canopy.

The new two-story structure will have 25,000 square feet of space, with 182 storage units. The existing two-story buildings (40,000 and 32,000 square feet, respectively) are already 90 percent occupied, developers told the planning board.
