What Are Traffic Impact Fees? When a person or business develops property in unincorporated Pierce County, they pay traffic impact fees (TIF). The fees are charges on new development that creates higher travel demand. They help pay for transportation system improvements needed by the new development.
Fees can only be used to add transportation system capacity required to support new development. They are not used for maintenance or operations work.
Traffic impact fees are used to help:
Reduce traffic congestion
Reduce delays at intersections
Build more roadway connections
Encourage economic development

Transportation Service Areas Pierce County is split and mapped into four Transportation Service Areas under the updated program. These mapped areas are based on future land use, growth, and transportation needs. Traffic impact fees by type of development vary within the mapped areas.
Projects The total cost of roadway and intersection projects to support future transportation needs is $700 million. Traffic Impact Fees are expected to bring in $253 million for these projects.
The projects include:
Road projects that address:
Concurrency (keeping roadways within allowed congestion levels)
Corridors and connectors (linking roadways to improve traffic flow)
Plateau corridors (Tehaleh and nearby communities)
Mobility (economic development)
Finished projects (waiting for further Traffic Impact Fees)
TIF Deferral Program
On October 26, 2010, the Pierce County Council adopted two ordinances. The laws allow builders to defer Traffic Impact Fees, Park Impact Fees, and sewer connection charges.
