The SPRTA fee program began in 2002 to fund approximately $124.9 million for regional transportation projects.

In fall 2006, the SPRTA fees were amended to reflect current construction cost estimates and updated land use projections for the South Placer region, resulting in the SPRTA fee program funding $153.03 million in transportation improvements in South Placer.

In 2007, the SPRTA traffic impact fee program was updated to include additional roadway improvement projects in an effort to fund over $191million in transportation projects.

The SPRTA traffic impact fee program was updated again in 2009, 2012, 2014, and 2024.

Changes to the fee program or allocations of fees require unanimous vote of all four members of the SPRTA Board of Directors.

Bond Opportunities for Land Development (BOLD) Financing

The BOLD program was designed to help developers and local public agencies in California finance public infrastructure needed for new development using municipal bonds issued by the California Municipal Finance Authority. SPRTA participates in the BOLD program and charges a $250 administrative fee to process each reimbursement request under this program.

SPRTA Fee Districts

The SPRTA fee area is divided into 10 fee districts, with fees calculated on a nexus-basis via the South Placer traffic model. (The Town of Loomis is not a SPRTA member; it is excluded from the fee districts and developments in the Town of Loomis do not pay SPRTA fees.) Fees are assessed on all development, including residential, commercial, and industrial.
