Today the Colorado House is hearing a bill to create a statewide turf replacement program (HB22-1151). I have an op-ed in Colorado Politics on why it is important to fund this program and help reduce urban water use in Colorado. Coloradoans can send a message to their elected leaders to support this bill with Western Resources Advocates’ action.
