    Michele Martinez

    Southern California Association of Governments Representative

    Council Member,
    City of Santa Ana

    Michele Martinez was raised in Santa Ana since the age of 11 and was the first person in her family to graduate from high school and earn a college degree; she attended Spurgeon Intermediate, Santa Ana High School, Santa Ana College and California State University Fullerton. Growing up in Santa Ana, Michele witnessed close family members and friends fall victim to drug abuse, gang violence and hopelessness. But Michele worked hard, never gave up on herself and realized at an early age that education was her only chance to get ahead.

    Inspired by a desire to give back to the community that helped raise her, Michele ran for Santa Ana City Council in 2006. She personally knocked on over 7,000 doors and to the surprise of the political establishment, won the election and became one of the youngest elected leaders in Santa Ana history. She was re-elected without opposition in 2010.

    Under Michele's leadership and hard work on the City Council since 2006, Santa Ana has seen a 32 percent drop in crime. In fact, Forbes Magazine recently listed Santa Ana as the 4th Safest City in the country among cities of similar population. Michele was instrumental in stabilizing the city budget by creating the first fiscal reserve policy. The general fund reserves have grown from 3 million to 41.8 million in the past four years. Michele is most proud of championing the city’s first, five-year Strategic Plan and Economic Development Strategic Plan. Finally, Michele kept her promise and helped the city increase its open space by 22 acres, and helped the city secure millions of dollars for active transportation to ensure pedestrian and bike safety, and improved and repaired nearly 300 miles of residential streets.

    Michele's priorities on the council include economic development, public health and safety and active transportation. Michele currently chairs the Finance, Economic Development & Technology City Council Committee and serves on the following City Council Committees: Development and Transportation, Public Safety, Legislative, and the Strategic Planning Sub-Committee.

    Michele also represents the City of Santa Ana on several regional boards; she currently is the 2nd Vice President for the Southern California Association of Governments (SCAG), the nation's largest metropolitan planning organization representing six counties, 189 cities and more than 19 million residents. She is an at-large member for the California League of Cities Orange County Division and also represents the Orange County Division on the League of California Cities, Transportation, Communication and Public Works Policy Committee. Michele is a board member for the Orange County Waste Management Commission. She is also the City’s representative on Orange County Council of Governments (OCCOG), a joint powers authority established to monitor, analyze and provide Orange County's technical and policy recommendations on all SCAG plans and programs. Michele also represents the City on the Transportation Corridor Agencies Committee (TCA). TCA are two joint powers authorities formed by the California legislature in 1986 to plan, finance, construct, and operate Orange County's toll roads.

    Lastly, she is a board member with the National Association of Latino Elected and Appointed Officials (NALEO); Michele also recently became a board member for the Southern California Latino Policy Center, a non-partisan, policy education and research organization.

    Michele graduated from California State University, Fullerton where she earned a B.A. degree in Criminal Justice. She is currently pursuing a Master's Degree in Public Health at Cal State Fullerton. In her spare time, Michele enjoys traveling, riding her bike and going to the movies.

    Ben Benoit

    South Coast Air Quality Management District Representative
    Councilmember, City of Wildomar

    Growing up in the Coachella Valley and starting his own computer networking business in 2001, Councilmember Benoit moved to the City of Wildomar in 2004. After personally going though the development process of building a house off of an unmaintained dirt road in Wildomar, he became a strong supporter of the effort to incorporate Wildomar as a City in order to bring local control to the community.

    Having been involved in Rotary and the Chamber of Commerce, Councilmember Benoit was encouraged to run for the Wildomar City Council in 2010 and was elected. He also served as Mayor Pro Tem in 2011 and 2014 and as Mayor in 2012 and 2015.

    Councilmember Benoit serves as Vice Chair for Western Riverside Council of Governments (WRCOG) and was a part of the Board when it won the President’s Award for Excellence from Southern California Association of Governments (SCAG) for WRCOG's HERO program. The HERO Financing Program is the nation’s largest Property Assessed Clean Energy (PACE) program, and Councilmember Benoit is a strong supporter of bringing this program to other municipalities throughout California.

    Serving on Riverside County Transportation Commission (RCTC), Councilmember Benoit has been a strong supporter of helping further Metrolink's reach into Riverside County. He sits on the Perris Valley Line (PVL) ad hoc committee, and is proud of his participation in bringing such an important project to fruition.

    In addition, serving on two conservation boards, Western Riverside County Regional Conservation Authority (RCA) and as Vice-Chair of Riverside County Habitat Conservation Agency (RCHCA), Councilmember Benoit understands the need to meet Federal mandates while supporting local businesses.

    Councilmember Benoit’s community involvement is motivated by his family. "My daughter Abby is the primary reason I decided to become politically involved. Wanting to ensure a better quality of life for her is the primary reason I spend so much time focused on improving our community."
