  • Director of Public Works: Siobhan Foster

    Siobhan FosterAs the Director of Public Works for the City of Pasadena, Ms. Foster manages one of Pasadena’s largest departments overseeing six key areas including finance and management services, engineering, construction, street maintenance and integrated waste management, parks and natural resources, and building systems and fleet management.

    Prior to joining the City in October 2011, Ms. Foster served as Public Works Director for the City of Riverside for seven years. Examples of the “best practices” launched by Ms. Foster include the award winning Clean Up Riverside’s Environment (CURE), a comprehensive recycling and public education program. Another award winning initiative, the Grease-to-Gas to-Energy project injects restaurant grease into the anaerobic digestion process at the wastewater treatment plant to increase methane gas production and reduce the natural gas requirements of the cogeneration power plant by 80% as well as reducing sewer line overflows caused by restaurant grease blockages from 30% of all calls to less than 1%.

    Other accomplishments during Foster’s tenure in Riverside include completion of $269 million infrastructure projects as part of the city’s Riverside Renaissance initiative, with another $489 million of additional projects now in construction or final design. Projects include railroad grade separations, reconstruction of freeway interchanges, and rehabilitation of Victoria Avenue. Examples of other cost saving and innovative solutions include the introduction of Asphalt Rubber Aggregate Membrane in lieu of
    traditional asphalt for street paving, reducing costs by 50 percent, and the installation of the first fuel cell in California that uses 100 percent biogas to generate 1 MW of power at the Riverside Regional Water Quality Control Plant.
