The document proposes a road diet and roundabout for the 2nd Street corridor in Chico, California to enhance safety for all modes of transportation. Key aspects include reducing 2nd Street to three lanes to add bike lanes, converting some parallel parking to diagonal parking, and installing a roundabout at the intersection of 1st, 2nd, and Flume Streets to improve traffic flow and reduce conflicts. The goal is to create a "complete street" that better accommodates vehicles, pedestrians, bicycles, and transit users through the downtown area.
