Mayor and City Council

Subject: Request for stop signs and speed bumps
On 4-30-98 Chief Zerwas and myself met with Council Member Thompson regarding
speed and stop sign complaints in the new Hillside Estate Additions off of 193rc1. We
toured the area in response to recent complaints regarding excessive speeds in the area.
We discovered that most of the development was void of stop signs in the area north of
193rc1 in the Hillside fifth, sixth, and seventh additions. The developer may yet correct
this, but we feel strongly that there were specific areas that demand stop signs and they
need to be pointed out.
The identified areas were noted and the recommended placements are noted on maps
enclosed with this memo.
The areas to be signed are:
Auburn at 196th Street
196th Street at Wilson
Wilson at 196th Avenue
196th Avenue and Auburn
Baldwin Circle and 196th Street
Auburn Circle and Auburn
In addition, we found the curves and hills on Auburn between 196th and 193rc1 actually
encourage traffic to cut the angle of the curve and speed through the downgrade. This
is very hazardous and there was evidence of vehicles leaving the roadway and driving
through yards.
We strongly recommend speed bumps be installed on Auburn on the north and south
sides of the hill area between 196th and 193rc1.
There is an identical problem on Dodge south of 193rc1. There is a request to add two
speed bumps on the opposite sides of the grade and curve south of 193rc1 as well. (See
attached maps for exact locations)
We did investigate the use of a recessed concrete speed bump instead of the standard
raised asphalt bump. In meeting with City Staff we discovered that from an engineering
standpoint, the recessed bump would not facilitate drainage; in fact it would more than
likely hasten road decay and would be an expensive and lengthy project to implement.
The raised bumps are easier to install and removal at a future date is much easier than
the recessed kind.

The suggested use of speed bumps as a means of slowing traffic down is unique to this
area. Auburn is one of only a few city blocks in Elk River which exceeds the maximum
length for a city block as dictated by ordinance. There are no cross intersections to erect
stop signs at and safety concerns prevent us from suggesting a mid-block stop sign from
being erected. The only other over size blocks are in areas or developments which do
not or will not have heavy traffic patterns or speed problems. We suggest using a
criteria for any future requests for speed bumps, that the block exceed the city size
limit; traffic flow be high and at excessive speeds and no cross streets exist which would
allow use of stop signs. The chances of other similar streets or situations existing is very
slim.
In addition, if these bumps do not work during a trial period of several months, they can
be removed by milling them off with little noticeable impact to the existing street
surface.
In checking other frequent areas of concern, we would request a four way stop be made
at Lowell and Highland. Recent reports of speeder in that area by Council Member
Farber resulted in targeted enforcement that netted a number of speed violators. A 4-
way stop would help insure speeds stay down as well as slowing down traffic at a key
area - the north driveway to the junior high. A fairly large number of students cross
Highland at the north driveway before and after school as well as during athletic events
and after school activities.
Our final request would be to re-evaluate Third and Gates - a frequent area of concern.
A traffic study was done last year and we feel that a new study should be done to
evaluate the current traffic flow to determine if the warrants exist for a four way stop. If
the warrants do not exist there are alternatives which the council may wish to look at.
These were brought up several years ago and include redesign of the intersection;
closing of the intersection and installation of a new sidewalk.
