TSDC Rate Studies with project list

With extensive public input, the City has identified a list of growth-oriented, multi-modal transportation improvement projects that will guide the spending of TSDC revenues over the next 10 to 20 years. 

The rate studies indicate projects to be constructed with TSDC revenues.  About one-quarter of the projects’ costs, representing that portion of new capacity projects that will serve new transportation trips, will be paid with TSDC revenues.  The remainder of project costs will be paid with other revenues, in part because a portion of needed investments address existing transportation needs (and TSDCs cannot be used for those). 

If the City does not collect as much money as anticipated, some projects will not be built or the City Council may choose to update and renew the project lists.  The City will ultimately determine which projects to fund as part of its annual Capital Improvement Plan process.  TSDC revenue can only be used for new capacity improvements.

Below are the links to the rate studies for the Citywide and Overlay TSDCs:
