  1. Growth of Traffic Stressin El Dorado Hills • First sequence of 3 maps highlights road segments operating at LOS F in 2011, 2016, and 2021. • Second sequence of 3 maps highlights road segments operating at 80% of LOS F in 2011, 2016, and 2021. Forecasts are based on linear extrapolation of actual traffic counts from two time periods: • Forecasts from long term data use ADT traffic counts from 1999 through 2011. • Forecasts from short term data use ADT traffic counts from 2008 through 2011.
