Transportation Asset Management Case Studies
Economics in Asset Management, The Florida Experience
Hillsborough County (see map) has an area of approximately 1,100 square miles and a population of 1 million. It is characterized by high rates of growth and development. The county's annual budget exceeds $2.5 billion, and the county employs some 8,000 workers.
Data in the Asset Management system helped the county to anticipate and respond to hurricane damage in 2004.
The Public Works Department is charged with the responsibility for maintaining and upgrading the transportation and stormwater infrastructure throughout unincorporated Hillsborough County. In addition, the department is responsible for maintenance and upgrading of roadway assets on a number of roads within the county's three municipalities: Tampa, Temple Terrace, and Plant City. The department is located on the 22nd and 23rd floors of the County Center building in Tampa, as well as at 10 remote operational sites strategically situated throughout the county. The department is organized into three principal divisions: Engineering, Transportation Maintenance, and Traffic Services. It employs approximately 650 full-time workers countywide (the majority in Transportation Maintenance), plus a number of temporary personnel. The department controls an annual operating budget of $70 million, and is responsible for $247 million of the county's 6-year Capital Improvement Program.
