COTTLEVILLE, Missouri — A proposal from Saeger Middle School sixth-grader Delia Nevatt helped change where residents can ride e-bikes and electric scooters in Cottleville. Aldermen approved the measure unanimously in October, the Francis Howell School District said Friday.

The measure permits qualifying devices on public sidewalks, trails and roadways under safety rules that include wearing a helmet and observing a 15 mph speed limit. The city named the measure for Nevatt.

Nevatt was in fifth grade at Warren Elementary when she addressed the Board of Aldermen in February. She and her father put her proposal in writing, and Mayor Stephen Thompson invited her to present it to the board.

Nevatt told the district that she organized her presentation around two points: why the restrictions mattered to her and what the city could change. The board’s October vote followed that initial public appeal.
