Speed Bumps and City Policy
City has established a policy whereby requests for the installation
of speed bumps (road undulations) can be processed and analyzed.
This policy establishes procedures and criteria for the installation
of these road undulations on public streets. What follows
is a summary of the procedure and criteria.
How to request a speed bump.
A request must originate from the residents
of the street upon which the undulation is intended and must
take the form of a formal petition in a format provided by
the City. These are circulated on all streets the City establishes
might be affected by the undulation. At least 75% of the
residents must sign the petition for the process to continue. Once a valid petition is received and accepted,
certain criteria (warrants) must be met for the undulation
to be approved.
Warrants which must be satisfied include
such things as: traffic volumes must range between 500 and
2500 vehicles per day, the speed limit must be 25 MPH, more
than 2/3 of the motorists exceed the speed limit or 85% must
exceed the limit by more than 10 MPH, the street must have
good visibility, the street must be residential in nature,
street lighting must be present and the installation won't
result in diversion of traffic to other residential streets.
The procedure for processing the request
includes verification of the petitions, collecting the necessary
traffic data to analyze the warrants, verifying compliance
with the warrants, making recommendations to the City Council
for approval and then field locating each undulation prior
The City will have an annual contract for installation
of road undulations which will be constructed per adopted
design standards. Installation will include all appropriate
striping, signing and road markings.
Prior to installation, the sponsoring group
of residents shall deposit with the City the required unit
cost for a road undulation under the annual contract. The
group has the option of obtaining a private Contractor to
install the undulations. The Contractor will be required
to obtain a permit and adhere to all elements of the standards.
