Lebanon— A New England plumbing and heating company hopes to begin construction of a 74,000-square-foot warehouse and office building off of Route 120 next spring, according to documents submitted to the city.

F.W. Webb Co. won approval last week from the Lebanon Planning Board to build the new facility at 68 Etna Road, the former home of New Hampshire Industries.

New Hampshire Industries, which makes pulley systems and machining parts, recently moved to Claremont, leaving behind a roughly 43,000-square-foot building that F.W. Webb plans to demolish.

In its place, F.W. Webb would construct a facility that houses nearly 7,000 square feet of offices, a 12,000-square-foot wholesale area and 54,000 square feet of storage.

The company estimates 35 people would be employed there when construction wraps up.

It’s unclear how much F.W. Webb intends to pay for the 5.1-acre property, which is still owned by New Hampshire Industries and assessed at $2.4 million, according to city records.

The new building would free up space at the F.W. Webb showroom across the street, said James Petropulos, an engineer with Nashua-based Hayner/Swanson, Inc., in an audio recording of the Planning Board meeting.

The company will continue operations there, he said, but with room for more retail products and space to host training events for local contractors.

Parking would be contained to the front and south side of the new building in 55 spaces, Petropulos said. There will also be six truck loading docks to the rear.

The operation would draw 30 vehicles to Etna Road during the morning peak hour and 18 in the evening, according to a traffic report submitted by the Concord-based firm Stephen G. Pernaw and Company.

That would amount to a reduction in overall traffic from New Hampshire Industries, according to the report.

Members of the Planning Board were generally in favor of the new building during a review last week, with only board member Joan Monroe opposing the project.

During the meeting, she expressed worries that the larger building would intrude on nearby wetlands.

“This building has gone too far to the back. The pavement is too far to the back,” she said in an audio recording of the meeting, adding engineers should have designed a larger buffer zone with more plants.

However, engineers countered that a storm water management plan calls for two areas of “porous pavement,” designed to curb runoff from the parking lot.

Water from the remainder of the property would also be captured in catch basins and piped into two detention basins in the rear of the site, they said.

Ultimately, the board voted 8-1 to allow the project to go forward.
