Kenner has a new city attorney and a new City Council member.

Leigh Roussel became Kenner’s chief legal adviser after the City Council ratified her nomination for the position during a meeting Thursday. She will replace her former boss, Mike Power, who resigned to serve as the Jefferson Parish attorney under former Kenner Mayor Mike Yenni, who was sworn in Wednesday as the new parish president.

Roussel, 45, has worked for the City Attorney’s Office since it was created in 2006, most recently as deputy city attorney.

“I feel like I have been able to get a good grasp of things and will have a smooth transition,” she said. “I’m happy the council has placed its confidence in me.”

Roussel, whose salary was set at $111,000, will remain in her new role at least until Yenni’s permanent replacement is elected late this year.

The council also voted to hire former Assistant Jefferson Parish Attorney Renee Hatch Aguilar to assume some of Roussel’s former duties. Aguilar, who will earn $66,000, spent seven years with the Parish Attorney’s Office under the administrations of Aaron Broussard and John Young.

Also on Thursday, local insurance agent Brian Brennan took the oath of office as an appointed, temporary replacement for at-large City Councilman Keith Conley, who resigned to become the top aide in Yenni’s parish administration.

Brennan previously served on a committee created to recommend changes in the city’s charter, as well as Yenni’s transition team when he was first elected mayor. He ran unsuccessfully for a district council seat in 2010.

“I’ll work weekends, nights and after hours around my other employment to meet with whichever constituents need me,” he said Thursday. “I don’t intend to be here just for the council meetings. I look forward to working with everyone to move the city in the direction that we’ve all strived to see.”

There had been questions from Kenner civic activist Richard Brown about whether Brennan’s council appointment last month was premature because it was made a few days before Conley’s letter of resignation had been received by the secretary of state.

But Kenner officials said a Secretary of State’s Office attorney told the city it was free to swear Brennan in, despite a statement from the agency’s press office that his appointment appeared to be premature.
