CITY OF EL MIRAGE SPEED CUSHION INSTALLATION PROGRAM  
 
Dated: July 1, 2020 
Revised: February 4, 2025 
 
Request & Evaluation - Residents may request speed cushions through a petition process to 
address speeding concerns. An engineering and safety evaluation of any speed cushion request 
will be made by the City of El Mirage to determine that the guidelines listed below are met. 
Since speed cushions have a wide-ranging impact not only on the vehicles crossing them, but 
also on the residents living on the immediate and nearby streets, the installation will be studied 
within the context of an overall Neighborhood Traffic Management Study. Speed cushion 
requests will be handled in the order in which they are received. City staff will coordinate with a 
Traffic Engineer to select the proposed locations for installation. The cost of the evaluation and 
the installation of any approved speed cushions will be paid for by the City based on the funding 
available. 
 
Speed - Speed cushions will be considered on local or collector streets where the posted speed 
limit does not exceed 30 mph. See Page 7 for Street Classifications and Page 8 for Speed Limits. 
Should the 85th percentile speed on these streets exceed the posted speed limit by 5 mph or more 
on any day or in any direction, speed cushions may be considered. If the speed requirements are 
not met at the time of the initial study, a second study may be requested twelve months later. 
Traffic Volumes – Each individual street location should be evaluated to justify installing speed 
cushions. Streets with total volumes (both directions) less than 400 vehicles per day will not be 
considered for speed cushions. However, if a study shows that area drivers are using a street as a 
"cut-through" route, then speed cushions may be installed regardless of speed or volumes. 
Emergency and Transit Routes – Prior to approving the speed cushion installation, the 
proposed locations will be reviewed with police, fire, and other emergency services. In addition, 
consideration may also be given to other potentially affected groups such as transit agencies, 
school districts, refuse collection agencies, etc. Should the proposed installation of speed 
cushions have a significant impact on providing emergency services or other critical services, the 
request for the installation may be denied. 
Neighborhood Surveys – Once it is determined that speed cushions are warranted, a petition 
process will be used where the individual or group that made the request (the “Requestor”) will 
be required to gather signatures from properties that have frontage along the affected street. City 
staff will determine the Petition Area and provide the Requestor with the signature form that will 
include the property addresses and a map of the proposed cushion locations. Within the Petition 
Area, sixty percent (60%) of the properties must approve the installation of the cushions. 
Signatures from either the owner or the occupant are acceptable. Petitions shall be completed and 
returned to the City of El Mirage within three months.

Several items of note regarding the Neighborhood Survey are as follows: 
• Either property owners or tenants may sign the petition 
• The City will attempt to contact the owner of any vacant lots for a vote 
• Properties that have rear frontage along the Petition Area will be included in the survey 
• If no response is received from a property, occupied or vacant, it will be considered a 
“no” vote 
Speed Cushion Installation – After obtaining all studies, approvals, and the Neighborhood 
Survey, City staff will present the project to City Council for approval. Upon Council approval, 
City staff will arrange to have its contractor install the speed cushions at the City’s expense. 
Appropriate signage and striping will be installed by the City. 
Speed Cushion Removal – Installations cannot be considered for removal for at least one year 
after installation. The process to remove the cushions must follow the same petition requirements 
and Council approval used in the original installation.
