About Us

The Roads and Airports Department is primarily funded by state and federal gasoline taxes and a portion of these taxes is returned directly to the County in amounts determined by statutory formulas.   In addition to this funding, some of special road and infrastructure development projects are funded through grant programs.  The Airports​ Division of Roads and Airport Department, is funded through the Airport Enterprise Fund which consists of the revenue generated from aircraft storage revenue.   In addition to this funding, some special airport projects are funded by the Federal Aviation Administration (FAA) and Caltrans. 

 The Roads and Airports department is comprised of 4 divisions; Administration Services, Infrastructure Development, Road and Signal Operations and Airport Operations.  Each division plays a key role to provide the traveling public with safe County roads by ensuring that the County maintained roads and airports are well maintained and meet the increasing demand of all types of users who travel in the Santa Clara County Roads system.
