Mr. Sohrweide said speed data was gathered using traffic counters in the area near the crosswalk.
The average vehicle speed ranged between 30 and 33 miles per hour and the 85"'percentile speed
was around 38 to 39 miles per hour. Speed data was also gathered using radar when children
were present. The average vehicle speed ranged between 30 and 32 miles per hour and the 85"'
percentile�speed was around 34 to 36 miles per hour.
Mr. Sohrweide explained that crossing the street requires gaps in the traffic. The Institute of
Transportation Engineers (ITE) has recommendations for school crossings and provides a
formula to calculate pedestrian delay. Mr. Sohrweide was on the site five different times. The
pedestrian delay measure during these times ranged from 12 to 48 percent. The ITE guidelines
would indicate a traffic control is necessary when the delay is 75 percent or greater.
The crosswalk is marked and there is advance signing. There is an issue for the line of sight as
vehicles approach from the west. Mr. Sohrweide explained that given the line of sight, the time
needed for a pedestrian to cross to the middle of the street would require a 20 miles per hour
approach speed of a vehicle. He said he would recommend a school speed of 20 miles per hour
when children are present.
Mr. Sohrweide said results of studies on flashing lights show different levels of effectiveness.
When new signs are posted, flags are posted with the signs for 30 days. He said enforcement
would also be required after making the change.
Mr. Sohrweide was asked to explain how the delay is calculated. He provided an example of a
ten-minute observation (600 total seconds observed). If the time during which gaps occurred was
200 seconds and the time in which there was no gap in traffic was 400 seconds, then the delay
would be 66.7% (or 400 divided by 600). He noted that a "gap" must be a minimum of 15
seconds between vehicles for this application. During his 11 minute observation, he noted 13 �
crossing opportunities, one as long as 52 seconds. In general, there was at least one gap per
minute. �
A resident aslced if the speed zone limit would apply during specific hours or when children are
physically present. Mr. Heuer said he understands the speed to apply during school hours when
children would be coming and going to school, not necessarily related to the physical proximity
of a child. Mr. Heuer noted that the tree foliage had been trimmed along the street to remove
potential obstructions. A resident asked about the use of speed infonnational signs. Mr. Heuer
said the City is cunently studying the effectiveness of such signs on Garden View Drive.
� MOTION: Mr. Asleson moved, second by Mr. Anglin, to recommend the establishment of a
school speed zone of 20 miles per hour on 142"d Street as recommended by the City's consulting
engineer. Motion passed 7—0.
Mr. Heuer said he expected the recommendation to be before the City Council on January 26"'.
Once approved, he estimated it would take approximately two weeks to receive the signs and
have them installed.
