Medians: Median Islands

Median islands are raised landscaped areas located in the center of a roadway in the middle of a block. Median islands narrow the travel lanes and separate opposing traffic flows.

Median Island


  • May reduce the speed of vehicles as motorists travel around the median


  • Some on-street parking may be eliminated
  • May require right-of-way acquisition

Eligibility Considerations

  • No more than one travel lane in each direction
  • Signs and vegetation must conform to the Clear Vision Area ordinance
  • Neighborhood Association Landscape Maintenance Agreement required if landscaping is included


Reduced Speed One Star   Reduced Volume No Star
