  • Development and Transportation Director

     

    Development and Transportation Director Jeanie RossillonJeanie Rossillon is the director of Development and Transportation (D&T) for Jefferson County, Colorado. She has served in this role since 2010.

    As department director, Jeanie oversees Planning & Zoning, Building Safety, Road & Bridge, Transportation & Engineering and the Rocky Mountain Metropolitan Airport. With 29 year of experience at Jefferson County, Jeanie has had several roles and leadership positions, including development review engineer and supervisor of both the design section and traffic & transportation group.

    According to county administrator Ralph Schell,“Jeanie works strategically, demonstrating strengths in planning, transportation and public policy; and always works to ensure what is best for Jefferson County.”

    Jeanie sees both upcoming challenges and opportunities in Jefferson County’s transportation issues. Citizens have started to demand transportation that accommodates multiple modes of transportation, which entails working not only with cyclists and pedestrians but also other citizens who are impacted by this demand. Most mountain roads were never designed for anything but cars, but lifestyles are changing and cyclists are increasingly using these roads, causing safety issues and accessibility concerns. This is a fundamental shift in the way the county plans transportation. However, it is now critical to retrofit the infrastructure already in place to fit the needs of the future.

    Additionally, the county has shifted from rapid development to one that is almost built out. As with everything, infrastructure continues to age and become outdated. Jefferson County has bridges that are 50 to 60 years old and will be in need of major repair. Bridges need to be repaired or rebuilt with an eye to how citizens now use our roadways. Many traffic signals are 20 to 30 years old, with controllers that run on old technology. This technology and others used to improve safety continue to change and Jefferson County has an opportunity to change with it.

    Jeanie has a Bachelor of Science degree in civil engineering from Colorado State University and a master’s degree in engineering from the University of Colorado at Denver.
