In 2013, Shane L. Silsby, P.E., Director of OC Public Works begins on November 4th.
In 2008, RDMD was renamed to what it is known today, OC Public Works.
In 2004, the decision was made to merge PFRD and PDSD and create Resources and Development Management Department (RDMD).
In 1997, the Planning and Regulation Divisions of the former EMA were removed from the structure and now comprise the Planning and Development Services Department (PDSD). The remaining EMA functions were combined with public works functions of the GSA, calling this new organization the Public Facilities and Resources Department (PFRD).

• Geomatics (Survey)
• Engineering & Permit Services

In 1996, the Board of Supervisors formally adopted a CEO model of organization by County Ordinance and filled the position. The CEO submitted a report to the Board that focused on internal restructuring and was adopted in June.
In 1992/1993, the Housing Department was added to EMA.
In 1991, the Agricultural Commissioner was adopted to EMA.
In 1976, General Services Agency (GSA) was formed by a split of Public Facilities from EMA.
In 1975, the EMA organizational structure was developed that in some areas was centered on programs, such as building and safety and planning, and in other areas was organized functionally (engineering, public works, maintenance, etc.). The organization evolved into four major divisions, Road Department, OC Parks District, Flood Control District, and Planning Department. Two of the four divisions were Planning and Regulation, comprised of the former Planning and Building and Safety Departments. Each division was headed by an executive level Assistant EMA Director who reported to the director of the agency.
In 1974, the CAO recommended that the county adopt the agency model of organizational structure, and begin with the Environmental Management Agency (EMA).
In 1968, the Board of Supervisors established the County Administrative Office and appointed its first County Administrative Officers (CAO). In the 1960’s and 1970’s, Orange County experienced rapid growth, transforming rural and agricultural areas into new housing developments and communities such as Irvine, Lake Forest, Mission Viejo, and Laguna Niguel. The population soon surpassed one million people and became its own metropolitan region.
