First thing that comes to mind is side strip / end strip nozzles for pop up spray bodies ...however they typically come in 4' x 10' or 5' x 15' sizes. You can dial them down, but i would doubt they would go down to only 1'. I have seen pop up bodies for micro misters, this might be your best bet. Not sure what brand or even if they are still available, head to your local distributor and ask about options. You are definitely going to want something that retracts back into the lawn.
