The Metropolitan King County Council on Monday gave its unanimous approval to the next step in assisting the growing number of drivers behind the wheel of “green” vehicles. The council adopted legislation establishing a $5 maximum fee for plugging into a county recharging station for the owners of battery and plug in hybrid electric cars.

Last year, the council approved a program to install up to 200 charging stations at county-owned, leased or partnering organizations’ facilities, such as Metro Transit Park and Ride lots.

Local and state governments have started to work together to implement EV infrastructure along the I-5 corridor.
