District 4 Supervisor
Warren Slocum
Representative for the Fourth District

I’m Warren Slocum and I serve on the San Mateo County Board of Supervisors as the representative of the residents of the 4th Supervisorial District. First elected to this office on November 5, 2012, my term began on January 7, 2013. Without opposition in my bid for a second term (which began January 3, 2017), I am honored to continue to serve the residents of San Mateo County and the 4th Supervisorial District for the next four years.

My Priorities

As the 4th District's Supervisor, I represent the cities of Redwood City, East Palo Alto, the areas of the City of Menlo Park east of El Camino Real and the unincorporated community of North Fair Oaks. I am committed to improving the quality of life for the residents of my district as well as the county as a whole. 

It has been my privilege to work closely with residents in the unincorporated community of North Fair Oaks as well as partner with non-profit organizations and elected leaders in the City of East Palo Alto, which was incorporated in 1983 and is the newest city in the County. These two areas are among the most culturally diverse in our County and have much in common—residents committed to strengthening families, advancing educational achievement, and fostering community connections.

In 2010, the County began a long-range visioning process which resulted in the development of the North Fair Oaks Community Plan – a policy document to establish goals and policies for land use, housing, health and wellness, parks and recreation, traffic circulation and infrastructure. It is the first update of the area plan for North Fair Oaks in 40 years. In July of 2013, the Board of Supervisors approved $12.5 million from Measure A funding to redesign Middlefield Road, in the heart of North Fair Oaks, from Pacific Avenue to 5th Avenue. The redesign will include the undergrounding of utilities, new street lights, and other streetscape changes which were approved by the North Fair Oaks Community Council and Board of Supervisors, and include a 3-lane roadway, wider sidewalks, and the addition of bike lanes.

I have been working closely with people from every quarter of the community – faith-based, business, youth, renters, homeowners, schools, nonprofits and interested individuals. I am impressed with the talent, passion and commitment that is being dedicated to ensure that the community is well-informed and has the opportunity to choose their future.

I wish to recognize the leadership of the North Fair Oaks Community Council, Sheriff Carlos Bolanos, our county departments, the California Highway Patrol, Menlo Park Fire District and the neighboring cities. Working together with our community partners, I believe we can make lasting and important changes to improve the quality of life for all.

Periodically, I hold office hours to meet with constituents and hear their concerns. To ensure that people can access the County and its services, Irving Torres, my bilingual Legislative Aide, helps overcome some of the linguistic access challenges. He helps ensure that Spanish-speaking residents have a voice.

We are fortunate that the voters approved Measure A in 2012 and reaffirmed an extension of this half cent sales tax for the next 20 years by a vote in the November 2016 election. The additional sales tax revenue, now known as Measure K, is helping fund special concerns like housing, preschool education through The Big Lift, deferred maintenance and infrastructure needs, and restore programs that were severely cut back during the 2008 Recession. And, through my District 4 discretionary funds, it has been my honor to partner with local organizations to address critical needs in our community. We still face some difficult financial decisions amidst an environment with unknown and uncertain federal and state funding and a new administration. We must remain prudent and wise to make sure that things work not just for today, but also for tomorrow. I will be listening to you as we make important financial decisions and looking for cost-effective measures to ensure the long-term fiscal health of the County.

Prior Service

Prior to my election to the Board of Supervisors, I served as the Chief Elections Officer & Assessor-County Clerk-Recorder of San Mateo County. It was exciting and challenging office; I transitioned the work in the Assessor’s Office from typewriters and adding machines to the modern era with online parcel information lookups, assessment information and mapping. As County Clerk, I was the first in the nation to offer couples the opportunity to broadcast their wedding ceremonies on the internet so that families and friends all over the world could share these special moments.

As the Chief Elections Officer, I introduced accessible voting equipment with language and adaptive features to ensure that ALL voters could participate in fair, private and secure elections. I also served as an officially appointed Election Observer in Albania at a time when democratic traditions were just taking hold. It was an honor to work with my team of observers. It made me keenly aware of the strengths of our electoral system; I also witnessed firsthand the commitment that people displayed to actively exercising their right to vote. 

As Recorder, I oversaw the conversion of recorded paper documents to recorded electronic documents and the creation of a publicly searchable database which made it easy to research property information. I took special measures to preserve the official record and make the content easily accessible. The office websites were rich with content designed to help residents and citizens conduct business online, find information, and get the latest updates in these areas. I was mindful of advances that made the office more efficient, the work environment more productive and safe, and that would cost the taxpayers less money over time. It was my privilege to serve in this capacity. 

About me

I have a passion for family, public service, technology, and history. My wife, Maria Diaz-Slocum, and our two sons (and our dog, Crockett and cat, Max) have made our home in Redwood City for more than 30 years.  Our sons were educated in the public school system and my wife is an elected Trustee of the Redwood City School District. We love this community and feel so fortunate to call the Peninsula home. I’ve watched our communities survive the tough economic times and revitalize, becoming more culturally, economically, and ethnically diverse and stronger than ever before.  We live in a special place.

As a young man, I was raised by a single father and we lived in San Diego. After graduation, I enlisted in the Army and served in Vietnam for one year – I was honorably discharged in 1969. I then attended San Diego State University where I earned my B.S. Degree in History. I have a reverence for people who serve their country in the military as they offer themselves in sacrifice to our country. I will work with others to make sure that our communities welcome home the veterans of today’s wars.
