Memorandum
TO: Mayor & City Council
Mark McNeill, City Administrator
FROM: Bruce Loney, Public Works Director
SUBJECT: Consider Traffic Study for Shakopee Avenue and Dakota Street
DATE: November 9, 2010
INTRODUCTION:
Attached is a traffic study for the intersection of Shakopee Avenue and Dakota Street, as
previously directed by the City Council. Staff will present the results of the study and
recommendation.
BACKGROUND:
;3D1.
The intersection of Shakopee Avenue and Dakota Street currently has stop signs on Dakota
Street legs. Recently, a sidewalk was installed on the east side of Dakota Street for a pedestrian
connection to Pearson Elementary School and 10` Avenue.
Also, during school arrival and departure, the school has crossing guards stopping traffic at the
intersection to allow children to cross the street.
Attached is the traffic and pedestrian volumes for this intersection. The traffic volume is such
that there is fairly equal volumes of each leg with Shakopee Avenue being 895 average daily
total (ADT) to 779 ADT for Dakota Street.
In review of this intersection, the warrants for traffic volume is not met for a four -way stop.
During the peak morning and afternoon hours, there is significant pedestrian and vehicle traffic
from all four legs. With the crossing guards working during these hours, the intersection does
act like a four -way stop.
One problem area staff did discover in studying this intersection is the parking along Shakopee
Avenue on the south side and close to the intersection of Dakota Street. This parking does cause
a sight distance problem for operation of this intersection. Staff is proposing parking restrictions
on Shakopee Avenue near Dakota Street to provide adequate sight distance.
Staff did meet with the Pearson School principal, Mr. Doug Schlief, and he was in agreement
with restricting parking near this intersection. The school will also continue their school
crossing guard program which has been very successful.
