Since January, the Ballard on the Park/QFC development has been the source of noise complaints from the neighborhood over the HVAC (heating, ventilating and air conditioning) units on the roof and the ventilation system from the parking garage.

In January, Jeanne Muir, spokesperson for the developers of the Ballard on the Park Apartments, told the Ballard News-Tribune the HVAC units, which can be heard humming from the adjacent Ballard Commons Park, would be visually and audibly dampened in March.

That schedule has since been moved back to April.

Muir said the shell of the HVAC dampening structure will be lifted into place on April 12. The rest of the structure will be assembled over the following weeks, she said.

The garage ventilation was causing noise issues for the apartments across from the north side of the development. Though Muir said she only heard complaints from one neighbor, she agreed with her.

"It was loud and needed to be fixed," Muir said.

She said an acoustical liner that was meant to be installed in the garage air shafts was never installed. The liner is on order and will be installed in a few weeks, she said.

Ballard on the Park's 268 units at 5700 24th Ave. N.W. opened for leasing in February. The QFC below the apartments opened in January.
