Medians: Median Barriers
Median barriers are islands located in the center of a street that continue through an intersection to block left-turn and through movements.
Advantages
- Prohibits dangerous turning movements and improves safety
- Reduces the volume of vehicles on a cut-through route that crosses a major street
Disadvantages
- Limits turns to and from side streets for residents and emergency services
- Some on-street parking may be eliminated on narrower streets
Eligibility Considerations
- Street width must be minimum 32 feet wide
- Cut-through traffic should represent 25 percent or more of the total daily street volume
- Accident history that would support the installation of a median barrier
- Signs and vegetation must conform to the Clear Vision Area ordinance
- Neighborhood Association Landscape Maintenance Agreement required if landscaping is included
