Serpentine Designs
Serpentine design refers to the use of a winding street pattern with built–in visual enhancements through a neighborhood, which allow for through movements while forcing vehicles to slow. The opportunities for significant landscaping can be used to create a park like atmosphere.
Such designs are usually implemented with construction of a new neighborhood street or during reconstruction of an existing street corridor. This type of design can be more expensive than other traffic calming options and needs to be coordinated with driveway access.
The serpentine street pictured above is a
curving roadway that helps slow traffic through the use of curbs
and landscaping.

Purpose:
• Changes the entire look of a street. Sends a significant message
to drivers that the nature of the road is not for fast driving.
• Often created where slow streets are being designed into new
neighborhood construction.
Considerations:
• Where costs are a concern, lower cost, equally effective traffic
calming strategies may be preferable.
• Most cost-effective to build as a new street or where a street
will soon undergo major reconstruction for utility or other purposes.
Estimated Cost:
The cost can be high ($60-90,000) to retrofit a street, but may be
no extra to build a new street with this design.
