El Dorado Hills Traffic:
It's about 44% of all traffic on El Dorado County's West Slope
... and EDH's share is still growing


Statistics for issuance of building permits for new housing continue to show more than half of all new housing in El Dorado County being directed to El Dorado Hills. This is reflected in El Dorado Hills' share of total traffic in the County. It is likely that EDH will have more than half of the County's total surface street traffic no later than 2020, possibly as early as 2015.

The graphs below are derived from county-wide traffic count data covering 10 years (1999-2009) from the El Dorado County Department of Transportation. The data depicts annually sampled traffic counts for specific locations on County roads.

Overview of El Dorado County traffic levels

Graphs and pie charts below associate traffic count data from each measurement point on the road system with either a "RAD" or an "Area". RAD definitions are as shown above, with boundaries defined by SACOG:  The Sacramento Area Council Of Governments.  An Area is loosely equivalent to a Community Region or a Rural Center and its surrounding rural territory, as defined in the El Dorado County General Plan. If desired, contact Paul Raveling for a more detailed discussion of Area definitions, including significance of the Census Designated Place boundaries for El Dorado Hills and Cameron Park.

This map is based on maps in the Regional Transportation Plan, which do not depict the two largest cities on the West Slope because both are still unincorporated:  El Dorado Hills and Cameron Park. The variant shown here adds approximate outlines of them based on their Census Designated Place boundaries.
