Shelving a legal challenge to the construction of a new Van Nuys fire station, Los Angeles city officials are doing a detailed study of the proposed building.

City officials last year approved plans for a new 18,500-square-foot station at Oxnard Street and Vesper Avenue in Van Nuys. The approvals prompted a lawsuit from neighbors, who said that the city should have done a full environmental study of the proposed project.

In December, city officials agreed to go back and further study the plan, prompting the opponents to drop their litigation.

On Wednesday, Los Angeles City Council members took up the lawsuit but didn’t recommend any action since the legal matter had been resolved, according to those involved in the case.

Mark R. Wolfe, attorney for neighbors who sued, said in an interview this week his clients are happy with the outcome.

“It’s unlawful for the city to do this without an environmental review,” Wolfe said.

A group of homeowners calling themselves the Tiara Group challenged the project in July.

Their lawsuit cited potential impacts of noise and possible contaminants from the soil during construction. In some cases, residents’ backyards abutted the proposed station, leading to concerns about living so close to the project.

Firefighters say a new station is needed to replace the existing 1930s-era Fire Station 39 on Sylvan Street. The building will be preserved, officials said.

The new building will have space for two fire engines, one ladder truck, two rescue ambulances and a command vehicle. Also planned are living quarters for on-duty personnel, a fitness and wellness area, office space, a conference room and an above-ground 4,000-gallon fuel tank.
