Transportation System Development Charge Update has begun

Posted: Wednesday, March 2

In December 2016, Clackamas County and the City of Happy Valley began the process of updating Transportation System Develop Charges. TSDCs are one-time fees assessed when a developer applies for a permit to create a new development or redevelop an existing property. These fees are used to pay for needed improvements to the transportation system caused by the additional traffic estimated to be created by the new development. See the fact sheet (pdf, 123kb) for more information.
