Curb Extensions: Chicanes

Chicanes are mid-block curb extensions that alternate from one side of the street to the other, forming S-shaped curves. This measure should be only used on residential roadways with less than 500 vehicles per day if reducing the street width to only one lane.

  • Reduces impervious cover and has a positive environmental impact

Disadvantages

  • Some on-street parking may be eliminated
  • Bicyclists may briefly have to merge with vehicular traffic
  • Local street drainage may be impacted

Eligibility Considerations

  • Operating speeds of 35 mph or greater
  • 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
