Traffic Impact Fee Program
Current and past fees can be found here!
The fees collected by the Traffic Impact Fee (TIF) Program (formerly known as the TIM Fee Program) are used to fund transportation improvements needed to accommodate growth anticipated by the County’s General Plan. The TIF Program requirements shall be applicable to all new development located within the Western Slope boundaries of the County.
Improvements funded by the TIF Program include, but are not limited to, new roadways, roadway widenings, roadway intersection improvements and transit. A TIF program is legally required to meet guidelines as established by Assembly Bill 1600 (California Government Code Sections 66000-66008). The Board of Supervisors receives annual reports establishing compliance with these guidelines; current and previous reports can be found
here.
