This is a video from the Iowa DOT.
This is from Jeff Speck.
Both are great. I had a 4 to 3 conversion proposed but it did not get approved. The Iowa video would have been helpful because the emergency responders claimed it would be harder to get through the traffic and that is addressed in the Iowa video. Unfortunately, I did not know about these at the time. The local business owners did seem to understand that the conversion would make it easier for customers to get in and out of their businesses. If you could get a couple of small business owners to speak in favor of the plan it would be a good start.
