Traffic Mitigation Fees

Napa Valley Business Park

All new development, or improvements to existing development, that will generate additional traffic within the Napa Valley Business Park (formerly known as the Airport Industrial Area) are subject to a traffic mitigation fee. The fee must be paid in full before any building permits for the development are issued.

Fees are determined based on the land use information found in the Trip Generation Manual published by the Institute of Transportation Engineers. The most common land uses are General Light Industrial and Business Park. Land uses that do not fall under the definitions for either of these most common uses are determined based on other information from the Trip Generation Manual or a site-specific trip generation study.
