Tensions rose between Sedgwick County commissioner Gwen Welshimer and Derby city manager Kathy Sexton this morning.

Sexton is a former assistant county manager.

Sexton was speaking against a zoning change and conditional use permit requested by the owners of Cook Airfield to expand their runway and build homes nearby. Welshimer accused Sexton of not telling Derby residents all the facts about the issue. She also said she was not allowed to speak at a Derby meeting.

Sexton countered by saying that she received a request from Welshimer to speak for 20 minutes at a meeting. Sexton said she then asked Welshimer what she wanted to speak about but didn’t hear anything back from Welshimer. Later, she said Welshimer responded she wanted to talk about the airport, but it was after the meeting in question.

Welshimer then said that was “neither here nor there” and focused on allegations that Sexton does not tell Derby residents all the information they need to form opinions on matters.

“Are you saying I’m not doing my job?” Sexton responded.

Commissioners have heard from several people in support of and against expanding the airport’s runway and rezoning the area.

Commissioners are expected to vote later today.
