About Jeff Hewitt
Jeff Hewitt was born in 1953 in Redlands, California and has spent most of his life in the Inland Empire. He graduated from Yucaipa High School and pursued his Bachelor of Science in Biology at the California State University, San Bernardino. While in college, Jeff started his own company by creating new applications for existing technology, then eventually applied what he learned to pool construction, including excavation, electrical, and plumbing. Since 1985 he has built his small business into the success that it is today. Jeff has six children and has seven grandchildren raised in Riverside County and has been married for 30 years to his wife, Wendy. The Hewitt family enjoys a semi-rural lifestyle with numerous horses, pigs, dogs, and cats that add to their quality of life and reinforce their roots in the Inland Empire.
In 2004, Jeff Hewitt was asked to serve on the Calimesa Planning Commission where he contributed to the development of the city for six years, working his way up to Chairman of the Planning Commission. In 2010, Jeff ran for a seat on the City Council with the vision to help residents cope with the rising cost of living. As a result of his determination to improve the quality of life for residents, he was elected mayor for three consecutive terms by his peers on the Council.
During 2016, Calimesa was facing a difficult financial situation that would inevitably lead them on a course toward bankruptcy. County fire services were taking a significant portion of the city budget, limiting the Council’s ability to provide basic services. With the support of Council members, Jeff spear-headed a project to carefully research all possible alternatives to move the city back toward fiscal solvency. Jeff took on leadership of the monumental task to create a professional City Fire Department on behalf of the Calimesa taxpayers, and saw it through to completion. This bold decision saved almost $3 million in the first two years while doubling the number of crew members on each dispatch. Most importantly, Jeff was able to improve the quality of life for residents without increasing taxes or fees.
In 2018, Jeff Hewitt was elected to the seat of County Supervisor for the Fifth District of the Riverside County, representing over 2.4 million residents. The Fifth District includes six incorporated cities (Moreno Valley, Calimesa, Beaumont, Banning, Perris, and Menifee) and over twenty-five unincorporated communities. In this geographically diverse landscape, Supervisor Hewitt has the opportunity to alleviate many of the problems and concerns raised by residents in the Fifth District and throughout the entire county of Riverside.

About Riverside County and District 5
Riverside County is the fourth largest county in the state of California and the eleventh largest in the nation with a population of 2.3 million residents. Its land mass stretches from just 14 miles away from the Pacific Ocean all the way to the Colorado River, encompassing, 7,200 square miles. Its governmental history can be traced to the 18th Century, when Spanish colonizers began to settle in the area. Prior to that several Native American tribes, including the Serranos, the Luisenos, the Cupenos, the Chemehuevi, and the Cahuillas occupied the land. In 1848, the signing of the Treaty of Guadalupe Hidalgo made California a territory of the United States and by 1893, residents living in the area carved out portions of San Bernardino and San Diego County to form Riverside County with its own Board of Supervisors.
The Fifth District of Riverside County is unique for various reasons, it has six diverse cities: Calimesa, Banning, Beaumont, Perris, Menifee, and Moreno Valley, the second largest city in the county. For residents in unincorporated areas, Municipal Advisory Councils (MAC) were developed to improve the quality of life for those outside city limits. In addition, the Fifth District is home to March Air Reserve Base, the Southern California Railway Museum, Lake Perris, and countless other destinations that make this place one-of-a-kind.
