Four lane, 50-foot wide undivided roadway with on-street parking on the east side. There are
two signals on this segment. No sidewalk on the west side of Alma. Uncontrolled crosswalk at
Forest Avenue. The railroad forms a barrier on the west side of Alma with limited crossings.
Results of attached engineering & traffic survey information support downgrading the 85th
percentile speed by 5mph due to the high accident rate. City will implement target speed traffic
calming measures. Maintain 25 mph speed limit.
