Convex Mirrors

Will the City Install a Convex Mirror at my Intersection?

The City of Lafayette does not install convex mirrors at intersections or driveways due to liability concerns.  If a mirror is installed and then later becomes misaligned and a collision takes place, the city could face legal risks.  Additionally, mirrors can create a false sense of security, as different drivers may focus on different areas of reflection, leading to inconsistent use.

In City staff’s experience many of the locations where mirrors have been requested the site distance concerns can better be addressed through the removal and/or trimming of vegetation.  If this is the case residents are encouraged to make a code enforcement request to have the fronting property clear the vegetation in the public right of way to improve the sight distance.

Can Residents Install Convex Mirrors?

Yes, residents are able to install mirrors at their own expense, but different rules apply depending on the location:

Public Right-of-Way

If the location that the mirror would be installed is located in the public right-of-way, the fronting property owner must enter into an encroachment agreement with the City.  This agreement would be recorded on the title of the fronting property and would transfer legal liability associated with the mirror to the property owner.

Once approved, an encroachment permit would also be required before installation within the public right-of-way can take place.

Please note that our public utility providers do not permit mirrors or other structures to be attached to their infrastructure, including power poles.

More information on how to apply for an encroachment agreement and encroachment permit can be found here. 

Private Right-of-Way

Residents are permitted to install convex mirrors on their own property  without an encroachment agreement.  However, the property owner would assume all legal liability for the mirror.  Please note that private property lines are usually located several feet back (and sometimes 15 to 20 feet back) from a public road.

Call the Engineering Department at (925) 284-1951 to determine whether property is located in the public or private right-of-way.
