The city is reviewing civil plans that would allow fixed-base operator Signature Aviation JAX to build a 42,100-square-foot hangar and office facility.

Plans submitted May 27 would be at Jacksonville International Airport at 14700 Yonge Drive where Signature Aviation has seven buildings.

The city initially began reviewing the FPO’s permit application April 4, but it was returned for corrections April 10 because the required civil plans were not included.

In aviation, an FBO — or fixed-base operator — is a private terminal at an airport that provides services for private and corporate aircraft and their passengers, including fueling, maintenance, hangar space and amenities such as lounges and catering.

The St. Johns River Water Management District is reviewing an environmental resources permit application submitted April 23. The permit is needed because the project involves wetlands. It had not been issued as of May 27.

City utility JEA approved a service availability request Jan. 6.

Schenkel Shultz of Winter Park is the civil engineer for the project.

Mike Mancuso is Signature Aviation JAX’s general manager.

Signature Aviation was formed in 1992 through the merger of Page AvJet and Butler Aviation. It is headquartered in Orlando and has more than 200 locations on five continents.

Renovations to Signature JAX’s fuel farm at JIA also are taking off.

The city issued a demolition permit May 12 valued at about $1.3 million to clear the way for improvements.

The project includes removing concrete pads and structures as well as fuel pumps and tanks.

Currier & Co., a mechanical engineering firm based in Los Angeles with an office in Tampa, is leading the work.

The renovation includes a 12,000-gallon self-contained storage tank and foundation, general spill containment, unloading equipment, piping system and supports and a fuel dispenser.

The city issued a permit May 14 for a 97.33-square-foot electrical building and concrete pad, valued at about $676,587.

On May 8, it approved a $634,373 permit to lay the foundation for the new storage tank.

On April 24, it permitted tanks and pumps for $9.6 million. On April 14, the city issued a permit for new containment positions to prevent spilled materials from spreading throughout the facility. That work is estimated at $515,853.

The fuel farm, at 2141 Cole Flyer Road south of the airport, services commercial airlines.
