A controlled burn along portions of South Boulder Canyon Ditch will start at 9 a.m. today, the city of Lafayette said.
The controlled burn for portions of the ditch that run through the Indian Peaks Golf Course was scheduled for Monday, but it was postponed due to windy conditions that made the fire too risky.
The purpose of the burn is to control noxious weeds and improve water flow through the ditch to reduce the risk of flooding.
City officials said the burn would be discontinued if winds pick up later in the day.
The National Weather Service forecast calls for calm winds and clear skies Tuesday, and breezy conditions on Wednesday.
